In the bulk of modern literature, it is consider a masterful epic unmatched in the realm of the written word. The novel centers around a family of workers who ar immigrants The Joads. When the novel takes place they be in California attempting to survive the scarce conditions of the depression. Steinbeck monitors and recounts the ups and downs of the family and their experiences in United States.The Grapes of Wrath is an indictment of the United States because much of the speckle is Steinbecks commentary on the rampant capitalism which literary sucked the land and the people dry during the 1930s. The story is based on real life excerpts of John Steinbecks orbit research. The real life conflict was created by greedy business men, and lending institutions which bought up land and employed workers to farm. The majority of these workers were pull down class immigrant families that were paid so little that their difference of opinions have often been par botheled to that of slavery which plagued the United States in the 16th and 17th centuries.The old adage was particularly relevant when examining this novel, as the rich bring about richer, the poor end up dead worked to death. Steinbeck is not casual in his assault of capitalism and it not fearful to express his disgust for the supposed American dream. He has a clear political viewpoint and asserts the great occurrence when property accumulates in too few hands it is taken away. And that companion fact when a majority of the people are hungry and cold they will take by force what they need. And the little screaming fact that sounds throughout all history repression works only to strengthen and knit the repressed. (333). A major theme developed by Steinbeck in The Grapes of Wrath is his believe that the survive of the set about class is based on their dedication to family. His approach is a delicate mixture of Marxism and Socialism, both of which promote cooperative living. In the context of the time, Steinbecks beliefs were not unspoiled controversial but also dangerous. The United States went through a two periods in which the government hunted after individuals they considered unamerican, the 1920s and the 1950s. This novel was written in the the 1930s.However, Steinbeck intricately weaves a tale of family strife, struggle, and survival, in The Grapes of Wrath, which has become a beloved and honored classic since its publication. Steinbecks depiction of the devastating conditions during the 1930s is historically accurate. In particular, Steinbeck articulately describes what a Dust roll actually is and how it was created.

The Dust Bowl was created due to lack of rain and also the over use of the land.Once pieces of land are over farmed t hey lose their nutrients and crops will not grow. These areas, once plush with grass and trees became virtual deserts. It was this drought which forced families, hungry and tired, to see out new hope in the west. The west promised folks clean and cheap living, and with access to regular work. Steinbeck describes the Dust Bowl in the following way, The wind increased, steady, unbroken gusts.The dusts from the roads fluffed up and spread out and fell on the weeds besides the fields . . .the sky was change by the mixing dust, and the wind felt over the earth, loosened the dust, and carried it away. For the people living in these devastated lands, this was a very accurate account as to what the hold was like for weeks and months. There are two general groups of people at conflict in the novel the rich bosses and the labor force. Steinbeck writes heart wrenching characters of the lower class which are just barely surviving. These workers are victimized by the greedy upper classes, t heir bodies treated like commodities.The audience can feel goose egg but empathy for these immigrant workers who toil the land drawing figures in the dust with bare toes, (10), while the men that own the land sit in their cars to talk out of the window, (43), do money on the backs of the poor folk. Steinbeck explains that these capitalists have never done a day of hard work in their life and their only motive in using big earth augers into the ground for soil tests (43) is to squeeze more money from the land they own. Steinbeck is also quick to point out that farmers and these land owners are different.While landowners corrupt the land leaving it near death with their iron penes and orgasms set by gears rape methodically, rape without passion. (50). Whereas the farmer works with the land keeping it healthy. He explains A bank isnt like a man. Or an owner with fifty thousand acres, he isnt like a man either. Thats the monster. (46). Steinbeck does offer an alternate choice to thi s laissez-faire(prenominal) nightmare which is represented by the Weedpatch Camp. This a town in which folks elect their own cops (400), and everyone who lives and works in the town has say about the choices are made.It is within Weedpatch, that all people including immigrant are treated fairly and with kindness. Steinbeck asserts that it is socialism that ensures that there is respect, and equality between all its citizens. It is in Weedpatch that Joads family ends up and while their struggle is not over, at least their victimization is. Steinbeck fully explores the cruel experiences that many migrant workers had to face in the 1930s and continue to face today. Steinbeck accurately and historically portrays the perils which many family has to overcome in the newly capitalistic culture in the United States.

My First Skydiving Experience Essay Example for Free

My First jump Experience EssayJumping is fun Sky descend is not just falling it is flyingthe closest we have been adequate to come to free, unencumbered, non-mechanical individual flight, says Mike Turoff in the book The Skydivers Handbook. I totally sustain with him because chute provides the maximum liberty that one can ever experience. In this article, Id like to describe to you my first jump in order to show you how a lot fun skydiving is. First of all, I learned about skydiving via the Internet and TV. There are countless pages of information about skydiving on the Internet. My first jump was a part of the accelerated free fall (AFF). AFF is a caterpillar tread for training new skydivers which includes cardinalteen jumps. Even though it has fourteen jumps, you will always remember the first one On the jump day, I went to the skydiving center at 830 in the morning. The AFF course started at 900. The course included basic parachute equipment information, free falling i nformation, emergency procedures, parachute opening, canopy control, and finally landing information. We were only four people in the classroom.The AFF students studied all the necessary lessons to make a safe skydive. We used special equipment to study parachute equipment, canopy control, and landing. After heptad long hours, at the end of the class, we took a written exam. We had to score 100% in order to pass the test. Everybody passed. Then came the gear-up part We put on our diving overalls, parachutes, altimeters which are used to watch the altitude during the skydive, helmets, gloves and goggles. There were many professional skydivers around, and they were giving us a hard time with nearly traditional skydiving jokes. I myself was the first person from the class who was going to jump. The next step was boarding the airplane. We used a twin otter double engine aircraft. That was a cock-a-hoop aircraft at to the lowest degree twenty skydivers could get on that plane. I was sitting between two jumpmasters (skydiving instructors) and in front of a cameraman. At that moment, I started tone of voice extremely worried and excited. The jumpmasters were talking to me, asking questions about my feelings.During the planes take off, all I could say was, Wow Then, I began watched my altimeter to see whether the altitude number was changing. I want to stop here to tell you something about the other skydivers on board. They were very relaxed although the aircraft was uncomfortable. Probably, I was the most frightened person on board. The others were telling jokes to all(prenominal) other and even drinking juice. Some of them were offering me candies and gum to celebrate my becoming a skydiver. In short, those guys were the craziest people that I have ever seen together. place you imagine someone drinking orange juice just before jumping down from thirteen green feet? Well, thats what they did. The altimeter was working perfectly. Only that fact was able to mak e me smile a little bit, but I was also considering what I could do if my parachute didnt open Finally, all the altimeters were saying thirteen thousand feet. The jumpers opened the door. I looked down and was able to see someone who had already jumped.Then, because of the cold air at that altitude, my goggles smoked up and I could scarcely see anymore. After a few seconds, the smoke disappeared and I could see the airplane was empty. All the other skydivers had already jumped except for my jumpmasters and myself. They told me to stand up and strait toward the exit door. I felt pretty heavy and could hardly walk.This may have been because of the heavy jump suit and parachute equipment. As I approached the door, I felt colder and colder. My cameraman was outside of the plane, and the jumpmasters were holding me tightly for a safe, very first skydive. My jumpmasters and I did the exiting procedures and finally let ourselves go out of the airplane. Those were the most arouse and enj oyable seconds that I have ever experienced. For a few seconds, I had a sense of falling.Then, I noticed that we were falling faster and faster as the seconds passed. After a while, after about the first ten seconds, I could see my cameraman filming my free fall. I was supposed to do some air maneuvers to pass to the second AFF level. I did those. My jumpmasters were still holding me and waiting actively for any possible emergencies. There was no longer any sense of falling and speed. It was mostly like floating in the air and hearing the wind deep in your ears. I periodically checked my altimeter to see the neat altitude to pull my ripcord and open the parachute. The necessary altitude to pull it was 5,500 feet. At that altitude, I gave a 5-5 signal to my jumpmasters, and I pulled my ripcord. That was extremely enjoyable. My parachute opened fast, and I felt a little shocked. Once my canopy opened, I checked it for any malfunction. It was perfectly okay and stable.The canopy flig ht, of course, was much slower than the free fall. I could see the beautiful environment from thousands of feet above. Then I looked for the drop zone landing area and saw it behind the clouds. I flew my parachute to the drop zone and very smoothly landed on the ground. I was one of the successful students who were able to walk right after touching down, without falling. The 5-minute adventure was ended I picked up my parachute and walked through the skydiving building. It was a sunny day. My friends and my family members celebrated the adventure for the rest of the day, and I decided to continue skydiving.Today, I am an AFF level four student with three successful jumps. However, of course, my first jump will always be the most enjoyable and unforgettable one. If I were you, I would not waste any more time. I would sign up for a very first jump as soon as possible. Once you fork over it, you will not be able to stop making jumps. At least, I have not been able to do so. I continu e to go skydiving whenever I can. I would like to give one more personal message Skydiving is a must-do activity, and everyone must try it at least once in his or her life. I guarantee you that it will be an unforgettable experience for you, too

The Problem Solving Techniques Philosophy Essay

The Problem Solving Techniques Philosophy EssayFrom the dawn of the age of the Man, tooth roots to a number of puzzles were desire later for generations, everywhere under the blue sky and above great heavens. But brace we really looked into that mavin place where we truly can stimulate them the Human Mind?From the moment you were born, you encountered a number of capers of which, survival was of utmost importance.

By instinct you made your first cry and took your very first breath the mysterious trouble of need to breath was solved. after a number of years, here you argon, act to understand why you need to learn how to solve lines.So whats there to learn about closure problems? What makes it meaning(a) to learn about solving problems? Is this going to be a bollocks up of time? All these questions will be answered by the end of this paper. But, just so that we know where exactly we be heading, I would like to bring your attention to the following statement.The significant problems we face cannot be solved at the same push aim of thinking we were at when we created them.-Albert Einstein- (1879 -1955)Therefore we are going to take a journey towards understanding what a problem is, how to understand the details of a problem properly, how to approach in solving a problem and finally how do we proceed beyond that. By the end of this tutorial, you will have gained the following skills. sagacity what a problem is.Approaching a problem with an investigative narrative.Using various techniques to address a problem and come to an concordant solution.Leading up on a solution to a given problem.What is a problem?In the simplest price, a problem is a challenge that is posed on an somebody or a group of people with the intention of overcoming it. Such a challenge creates a state in the environment that requires resolution. So when you come across a problem, al expressions think in name that this is a state that needs be resolved. Never ever think of it in terms of being a hazard that needs to be tackled and thrown off of your head as soon as possible.Problems and ConfidenceAny problem can be addressed in a number of ways and some of them may fail while others would bring agreeable results. There could be situations where the only if way to reach to an agreeable solution is to make some compromises. Never the less, taking a positive attitude towards problems covers the most important factor needed in solving a problem confidence. But you mustiness also understand that just like under confidence gets in the way of solving a problem successfully, so would over confidence. It is by striking a balance you will reach a state of mind best suited to addres sing a problem.When you wish to solve a problem, having faith on yourself itself will not take you anywhere. Instead, you should strengthen yourself with a number of techniques and tools that will help you build that confidence. The objective of teaching you this particular module is to give you a starting point on such techniques, tricks and tools. Then you may use these tools at your disposal and go a successful problem solver.Problem Investigation TechniquesJust like any heterogeneous endeavor, problem solving itself consists of a number of interrelated tasks that must be addressed in a gradual, step-by-step manner. This approach makes understanding, planning and understanding a problem better, allowing you to come to a solution that is agreeable enough.In the simplest terms, we are trying to understand a problem so that we can plan ahead and face it well. This is what we are trying to achieve by analyzing a problem. Given below are a set of go you may take in getting a bette r grasp at the nail down of a problem.State the problem you are about to solve in a well detailed manner Try to be precise as well as detailed. Even though you already know the problem well enough, by making sure that you actually note it down, you will have the advantage of your visuals sensory system coupled with part of your brain trying to come to a better interpretation of the problem. In preparing a problem statement, you may ask the following questions from yourself.Is it a question you must answer?Is it an obstacle you must overcome?Is it a person you must persuade?Is it a conclusion you must make?Is it an opponent you must defeat?Is it a goal you must achieve?Is it a goal you must set?Is it a problem you must define?Has the problem being defined for you?State the parts of the problem that can be addressed separately The great emperor Julies Caesar is attributed to the grammatical construction Divide et Impera in Latin which translates to Divide and Conquer in English. We will be taking the same approach in dividing a relatively complex problem into a smaller and comparatively less complex set of problems that can each be addressed respective(prenominal)ly. During this step, you may ask following questions from yourself.Is the problem really a collection of many problems?Can you divide the problem by defining terms? atomic number 18 there any implicit terms to define?Can abstract terms be restated in concrete terms?Can the problem be solved in steps?Are half-way solutions possible?Can the problem be substantially solved?Is a partial solution better than none?State the problem in the broadest terms There is an inherent deficiency in most forms of human communication in delivering sub-textual messages via common communication methods. Same could have happened with the problem you are trying to solve when it was introduced to you. Therefore, instead of looking at the problems face value, you may take an effort to take a look at the big picture. In doi ng so you may ask following questions from yourself.Is the problem part of a larger one?Is it geographically broader?Is it an effect of a larger problem?Is it only a sign or symptom?Can concrete terms be restated in abstract terms?Is a general solution possible?Is a political solution possible?Is a group solution possible?State your role in solving the problem Identifying what your role in solving a given problem is very important. Some problems are posed on an individual, and some are on a group. Just like one must know how to play his role in a group so that an agreeable solution can be reached, the same is true with an individual trying to solve a problem. One must understand what type of a role he will be playing (i.e. evasive, neutral, hasty, etc.) to better identify himself in the contextual environment of a problem that needs to be solved. You may ask following question from yourself in undertaking this step.Was the problem presented to you?Do you accept the challenge?Should you volunteer yourself to solve the problem?Are your emotions dependency factors in reaching a particular solution?Will you be presumptuous a certain role in solving a problem?State the names and interests of others who are involved Knowing what role you will be playing in solving is never complete without knowing what other parties are taking an interest in the same problem, problem solving process, or the outcomes of the final solution. Close attention must be paid to observing their interests and roles they play in any given problem, let it be friendly or hostile. Ask yourself the following questions in completing this task.Has this problem being presented to others?Can you delegate the problem?Can you delegate selected parts of the problem or the problem solving process?Who else is interested in the problem itself or the solution to the problem?Who else is directly affected by the solution?Who else is indirectly affected by the solution?State solutions to a similar problem foun d in the past There is a very popular term not only in the academia, but also in various other fields, that one should never reinvent the wheel. It is in fact figurative speech used in order to say that one should never waste resources in perfecting an entity that is already perfect for a given purpose. In the same manner, it would be a waste to solve a problem that has already been solved before in an agreeable manner. You may simply use such solutions as references and either hold in them directly or adapt them to the specifics of a given problem. Take some time and ask yourself the following questions.Were you able to identify any problems from the past that are already of the same nature?What similarities were you able to identify?What dissimilarities were you able to identify?Can solutions to such problems be applied to the problem at hand?Has your seek provided with any agreeable enough solutions to your problem?State the affects of time factor over the problem and the solut ion Even though a number of factors are needed to be managed precisely, none of them precede the importance of managing time in most of the situations. In time-critical problems late solutions are the same as no solutions at all. Therefore in solving a problem, ask yourself the following questions and try to understand how exactly the time factor affects the end solution.How will the problem evolve over time?Is there a deadline for the problem to be solved?What are the possibilities of postponing the solving process for a given problem?State your proposed solution to a given problem It is not enough that you understand the problem itself and previous solutions you must also come to the point of proposing a solution that is agreeable enough as well. First step to clarifying the problem is listing down the solution clearly enough that no part of it is misunderstood, leading to pass on unexpected problems. During this stage, ask yourself the following questions.What actions must be t aken?Who must take each and every action?When must each action be taken exactly?What steps must be taken in the case of a failure or setback?State if the proposed solution is practicable enough to be used in the context Once a problem is properly analyzed, understood and solution provided, the flow is not completed until you take initiation in doing a figurative postmortem of your own solution. Here you will try to understand how feasible a solution actually is compared to the put on the line of the problem itself.What are the dependencies the provided solution has?Is the solution resource conserving?Does the solution meet various budgetary constraints?Is the solution legally unimpeachable?Is the solution morally acceptable?Now that you have completed a tiresome set of tasks that will actually help you understand a problem properly, address various steps in solving a problem, now you are ready to actually solve the problem.

Research essentialiness in addition be make into the different manufactures of batteries within South Africa. Once we confine a fuller understanding of the basics, we get out be adequate to analyse in more detail the characteristics of different types of batteries, in this case focvictimization on the some habitual ones. We will excessively look into how these batteries impact the environment whether it is in a po sitive or negative way and how we potentiometer properly dispose of these batteries so as to inhibit any harm they may inflict, both on the environment and humankind.What is a stamp outpouring?A battery consists of a multiple number of electrochemical stalls conjugate together, which converts chemical energy to electrical energy by means of self-sustaining spontaneous electrode reactions in order to produce an electrical authoritative when connected to a closed electrical circuit.Each electrochemical cellular phone comp modernizes of dickens half cells which contain an electrode and an electrolyte. The two half cells ar connected by a salt couplet in order to create ionic contact for the two electrolytes for the free take to the woodsment of ions and to prevent the electrolytes from mixing in the case of two different resolutions creation apply, which would cause unwanted side reactions. An example of a salt bridge would be a strip of filter paper which has been soa ked in a solution of potassium nitrate. Other means of separation of electrolytes include the use of gel solutions and porous pots. In the majority of modern, commercial batteries, a different electrolyte is used in separately half cell, and to prevent mixing, a porous separator is used which only al scummys the passing through of ions.The electrolyte of the two half cells is a solution which is capable of conduction of electricity due to the presence of free negatively and positively superaerated ions. In one of the half cells, positively aerated ions (cations) argon attracted to the cathode (positive electrode) while in the other half cell, negatively charged ions (anions) be attracted to the anode (negative electrode). In the oxidoreduction reactions which cause the conversion from chemical energy to electrical energy, oxidation (loss of electrons) occurs at the anode to the negatively charged electrons and reduction (gain of electrons) occurs at the cathode to the positively charged electrons.Illustration of a Redox reactionThe electrochemical cell produces an electromotive force (emf) and is the exit in potential difference amongst the two electrodes. For example, if the one electrodes voltage is 3V and the other electrodes voltage is 1V, the net emf of the cell is 2V.Primary and Secondary CellsBatteries ar sort into two main groupsPrimary batteries irreversibly convert chemical energy to electrical energy (once the initial supply of reactants has been used up, the electrochemical reaction cannot be reversed by inducing an electrical real and thus the energy cannot be restored to the cell).Secondary batteries can be recharged by reversing the electrochemical reaction by inducing an electrical legitimate.Primary CellA primary cell is any type of battery of which the chemical reactions atomic number 18 irreversible the chemical reactants cannot be restored and thus a primary cell has to be discarded once it is depleted.Primary batteries come in to use for when long periods of time in storage ar dribbleed as a primary batteries are constructed to consecrate lower self-discharge rates than secondary batteries, so all of the ability is available when in need for useful purposes. Devices that require a excellent amount of current for a long period of time also use primary batteries as the self-discharge current of secondary batteries would exceed the rouse current and cut down service time to a few days or weeks (eg, a torch must work when needed, even if it has been on a shelf for a considerably long period of time. Primary cells are also more cost-efficient in such a case, since secondary batteries would use only a small percentage of available recharge cycles.Reserve batteries are capable of achieving a rattling long storage time (ten years or more) without the loss of capacity, by physically separating the components of the battery and only assembling them again at times of use. hitherto, such batteries are expe nsive.When in use, primary batteries become polarized (hydrogen builds up at the cathode and in turn reduces the achievementiveness of the battery. In order to remove the hydrogen, a depolarizer is used. Depolarizers can be mechanical, chemical, or electrochemical. Although previous attempts have been make to create self-depolarizing cells by roughening the surface area of the copper plate to encourage the hydrogen bubbles to detach, they have had a abundant failure rate.Examples of primary cellsAlkaline cellAluminium cellLithium cellMercury cellZinc-carbon cellSecondary batteriesA secondary battery is cell of which the chemical reactions can be reversed and therefore energy can be restored to the cell. This is done by connecting the cell to an electrical current. The electricity initiates non-spontaneous redox reactions in order to restore the chemical reactants.Secondary cells, when purchased, could not be used immediately and would have to be recharged before use. Although toda y, most secondary cells are created with lower self-discharge rates, allowing the purchaser to use the battery immediately as the battery already holds about 70% of the stated capacity.The energy used in charging secondary batteries mainly comes from AC current using an adapter unit. Many battery chargers take several hours to recharge a battery. Most batteries are capable of beingness recharged in a much smaller amount of time than what most commercial, simple battery chargers are capable of. Although a few companies are producing chargers that are able to recharge AA and AAA size NiMH batteries in just 15 minutes, high rates of charging (15 minutes to 1 hour) will cause long term damage to NiMH and most other rechargeable batteries.Secondary batteries are susceptible to damage by means of reverse charging if they are fully discharged.Also, attempting to recharge primary batteries possesses a small chance of causing an explosion of the battery.Flow batteries, which are not commonl y used by consumers, are recharged by replacing the electrolyte unruffled of the cell(s).The technical notes of battery companies often refer to VPC. VPC means volts per cell, and refers to the individual secondary cells making up the battery (eg, to charge a 12V battery which contains six cells of 2V each at 2.3 VPC, needs a voltage of 13.8V across the terminals of the battery).Most NiMH AA and AAA batteries rate their cells at 1.2V. However, this is not a relatively large problem in most devices as basic batteries voltage drops as the energy is expended. Most devices are constructed to continue to operate at a reduced voltage between 0.9V and 1.1V.Industrial secondary cells are used in grid energy storage applications for load leveling, where electrical energy is stored and is used for the duration of peak load periods, as well as for renewable energy purposes such as the storage of electrical energy which has been generated from photovoltaic arrays (solar panels) during the da y to be used in the evening.By recharging cells or batteries during periods when demand for power is low and then returning the energy to the system (or grid) during periods when the demand for power is high, load-leveling aids to eliminate needs for exceedingly expensive power plants and also eases the cost of generators over a greater period of operation.Discharge and Recharge Cycles in BatteriesRecharge and discharge cyclesThe purpose of a cell is to store energy and release it at the given time in a contained manner however, only secondary cells can be recharged. The electrochemical reaction that occurs in the fluid electrolyte of a wet (secondary) cell is reversible, unlike dry or primary cells this allows the charge to be restored. The trio most popular types of rechargeable batteries that are found today are nickel-based (NiCd NiMH), lithium-ion and lead-based cells.C-rateC-rate is the measurement of the charge and discharge current of a cell. Almost all trans take-away ce lls are rated at 1 Coulomb (1C). This means that a 1000mAh battery, if discharged at 1C, would give 1000mA for one hour. The same applies if the discharge was halved (0.5C) this would provide half the amount of current (500mA) for twice the duration (2 hours). A 1C cell is referred to as an hour discharge, the most common portable cell we have is the 20-hour Lead-based discharge cells (0.05C) found in cars.Lead- mordant CellsThe C-rate of a lead-acid cell is not set to a constant like other cells, as achieving 100% capacitance at any discharge rate is difficult. The offset is done in order to compensate for the varying measurements at the differing currents automatically adjusting the capacity of the cell is discharged at a high/lower C-rate than originally thought. man-portable lead-based cells are rated at 0.05C given a 20-hour discharge. The offset is represented in Peukerts law.Peukerts law represents the capacitance of a lead-acid cell in terms of C-rate. As the rate of disc harge increases, the batterys available capacity decreases and vice-versa.Fast and slow discharging/recharging of a lead-acid cellAt the beginning of when a lead-acid cell is charged or discharged, the chemicals present in the acid electrolyte at the point between the positive and negative electrodes (the larboard) are affected. The wobble in these chemicals, results in a charge that is formed at the port. This interface charge eventually spreads throughout the active material in the hatful.Fast charging a completely discharged cell for a couple of minutes causes the charge to develop near the interface of the battery, when leave for duration of time ( a couple of hours) the charge spreads throughout the volume of the cell, meaning the interface charge of the cell is too low for the cell to actually function. Likewise, if the cell is discharged quickly it will appear to be dead but it has only lost its interface charge. Meaning subsequently a few minutes wait, it should be able to function.If the battery is charged slowly, over a long duration of time, then it will become more fully charged (than that of a fast charge). This is as a result of the interface charge having more time to redistribute itself into the volume of the electrodes and acid electrolyte, as well as itself (the interface charge) being recharged. In addition, if the cell is being discharged slowly, then when the battery appears to be has died it most probably has been fully discharged.Depth of discharge of Lead-acid batteriesThe depth of discharge (DOD) of a cell is the percentage of the batterys current that it is discharged per hour. The optimum temperature a battery should be charged/discharged is around 25C (77F), anything high and up until 50C (122F), is tolerable. The cycle life of lead-acid batteries is exactly proportional to the depth of its discharges.200 cycles subsequentlyward battery discharged fully (100% DOD)500 cycles after battery partial discharge (50% DOD)1000+ cyc les after battery shallowly discharged (DOD)Lead-acid batteries are charged not be discharged over 1.75V/cell, nor should it be stored in a discharged state. The cells of a discharged lead-acid sulfate, a condition that renders the battery useless if left in that state for a few days. Always keep the open terminal voltage at 2.10V and higher.Charge and discharging of lithium- ion cellsDischarging Lithium-ion batteries only works within the temperature make up ones mind of -20C to 60C (-4F to 140F). The chemical reaction is reversed within the battery and the current flow is carried from the negative to the positive electrode by the movement of Li+ ions, through the non-aqueous electrolyte. The cycle life of lithium-ion batteries is directly related to the batterys depth of discharge, the higher the capacity of discharge, the less number of cycles it can go through.Charging Lithium-ion cells requires an impertinent electrical power source (charger) that applies a higher voltage but of equal difference (normally 4.05V/cell) to that developed by the batterys own chemistry. This causes the current to flow in the opposite direction, meaning the lithium ions migrate from the cathode to the anode, and they become intercalated in the porous electrode material of the cell, thereby replenishing its charge.Charge and discharge cycles in nickel- based batteries (NiCd NiMH)The reliability as well as longevity of atomic number 28-based batteries hinges, predominantly, on the quality of the charger. Nickel- based cells should always remained cool when being charged as elevated temperatures shortens battery life. A rise in temperature cannot be avoided due to the chemical reaction in the nickel-based cells, yet in order to be charged properly the spike in temperature has to be as short as possible. If the temperature of the battery remains higher than room temperature for an ample amount of time, the battery should be removed, as it is not being charged correctlyNickel-ba sed batteries can be charged at several different rates using a variety of chargersSlow charger of nickel- based cells take between 14-16 hours at a fixed charge of 0.1C (1/10 of nickel cells 1C capacity) this however causes crystalline formation within the cell, this causes the subsequent drop in voltage at that point in its charge cycle where recharging began, as if the cell is being dischargedRapid Charger of nickel-based cells takes between 3-6 hours to fully charge, this charger switches the cell to trickle charge (charging with a very small current) when it is ready.Fast charger of nickel-based cells takes approximately one hour to charge the battery this is the preferred way to charge nickel-based cells as it reduces crystalline formation or memory within the battery however, the battery is at a higher risk of overcharging, which can damage the battery.However all new Nickel-based batteries should be trickle-charged for a day before being used as this ensures that all cells a re equally charged within the battery.Nickel Metal-hydride batterThe charging voltage of NiMH ranges between 1.4-1.6 V/cell fully charged and 1.25 V/cell during discharge, down to about 1.0-1.1 V/cellNickel candela batteryThe charging voltage of NiCd is between 1.3 -1.4V per cell when fully charged and about 0.8-1 V when dischargedIf the nickel-based batteries are discharged at a rate higher than 1c, the end of discharge point is lower than 0.9V a cell. This compensates for the voltage drop at higher temperatures induced by the infixed fortress of the cell also other factor which contribute to the drop (iring, contact etc) the lower point produces better capacity readings for the nickel-based cells when discharging at lower temperatures.South African companies that manufacture batteriesThe Willard Battery Company is a fully owned South African company that manufactures motor vehicle batteries and is located in Roodepoort, Port Elizabeth. The main types of cell they manufacture ar e SLI lead-acid batteries for use in powering the starter motor, lights, and the ignition system of a cars engine.First National battery is a battery manufacturer that came about after the merger of four smaller battery-manufacturing companies (First national battery, Raylight, Oldham and Chloride). Their main products are SLI lead-acid batteries used in vehicles (passenger and commercial), mono-block lead-alloy batteries used in railways, lead-alloy cells (deep-cycle, RR, tubular and Solar) used for as standby permit batteries in marine vehicles and as well solar batteries.Deltec Power Distributors is a South African distributor of a wide variety local and internationally produced high quality Lead-calcium car batteries and standalones, since 1979.SABAT Batteries is part of Powertech Batteries, a branch of the Altron Group South Africa. SABATSs main operations include the manufacture and distribution of lead-acid cells, low-maintenance hybrid lead-calcium cells, and maintenance-fr ee calcium and normal calcium batteriesDixon Premium batteries is South African company founded in 1953 and is based in Vereeninging Johannesburg. Their main product is a 12-volt SMF lead-acid cell for use in motor (and/or other) vehicles.Free Start Power is a Local company that manufactures SLI lead-acid batteries for the use in vehicles (commercial, passenger and aquatic)The Most Popular Types of BatteryThe three most common and more popularly used types of batteries are the lithium-ion battery (examples are in notebook computers and medical devices), nickel-based batteries (such as in two way-radios and power-tools in the nickel- cadmium battery and laptop computers and mobile phones in the nickel- surface-hydride battery), and of course the lead-acid battery (mostly found in wheelchairs, emergency lighting system and cars).Nickel-cadmium BatteryThe nickel-cadmium battery consists of a nickel (III) oxide- hydroxide (Ni(OH)3) plate as the positive electrode (the cathode), a cadmiu m plate as the negative electrode (the anode) and an alkaline electrolyte usually made from potassium hydroxide (KOH). There is also a separator that isolates the two electrode plates. These are all rolled into a spiral shape and enclosed in a casing using a surface, self-sealing plate (known as the jelly-roll design). This original cell design is what differentiates the nickel-cadmium battery from the older, more traditional alkaline cell. The structure of the nickel-cadmium cell allows more of the electrode to be in contact with the electrolyte, thus lowering the internal resistance of the battery and increasing the maximum current that can be delivered, whereas in the alkaline cell a graphite rod is placed in a casing filled with the electrolyte, resulting in a much smaller area of the electrode being in contact with the electrolyte.In a nickel-cadmium battery, the chemical reactions are as followsNickel electrode (cathode)2NiO(OH) + 2H2O + 2e? 2Ni(OH)2 + 2OH?Cadmium electrode ( anode)Cd + 2OH? Cd(OH)2 + 2e?Therefore, the net reaction in the cells of a nickel-cadmium battery is2NiO(OH) + Cd + 2H2O 2Ni(OH)2 + Cd(OH)2When a nickel-cadmium cell is tested on a device such as a cell phone, it typically produces a very low internal resistance about 155 milli-Ohms (m?). This resistance is largely affected by the state of charge the battery is in. The resistance is highest during two stages when there is a low charge and immediately after charging. Therefore, the maximum possible current is actually achieved after a period of rest after the battery has been charged, with the internal resistance varying between 100 to 200 milli-Ohms, with the cell emf ranging from 0.0 to 1.3V.Both the maximum current and the capacity of this cell are influenced by the internal resistance. As previously stated, the low resistance means that the nickel-cadmium cell can produce quite a high maximum current. The secondary cells that make up the nickel-cadmium battery each have a capacit y of about 1.2 Volts therefore a standard battery with a 7.2V capacity (6 cell pack) should produce around a 900 mA current without diminishing for a long period of time. This ability of the battery to provide a high current for extended periods makes it one of the most popular battery types.Nickel- coat-hydride BatteryThe main (and possibly most distinguishing) difference between the nickel-metal-hydride battery and the nickel-cadmium battery is that the nickel-metal-hydride doesnt use any cyanogenetic metals. Where the nickel-cadmium battery uses cadmium to form the hydrogen-absorbing anode, this battery uses an electrode made from a metal-hydride, typically an alloy mixture of Lanthanum, cerium, neodymium, praseodymium and possible other rare-earth elements, as well as a metal that is usually cobalt, nickel, manganese and/or aluminium. This makes the metal-hydride anode an intermetallic compound.Lithium-ion BatteryThe lithium-ion battery is one of the newest and fastest developi ng technologies in the battery human being. As this cell was introduced to the public shortly after the nickel-metal-hydride battery, some believe that the nickel-metal-hydride cell was a crucial step in the development of the lithium-ion cell.In a lithium-ion cell, the electrodes (anode and cathode) are made from compounds which lithium can move through. When lithium is moved into the electrode it is called migration when it moves out it is called extraction. The movement of the lithium, via the electrolyte, between the anode and the cathode depends on whether the cell is charging or discharging. The reason lithium-ion is used instead of lithium metal is that lithium metal is highly unstable when used in the batteries discharge and recharge cycles, making it very unsafe for conventional use. Therefore, this battery is a non-metallic battery.Lead-acid BatteryAs the summons suggests, this type of battery consists of two substances Lead and an acid. There are two types of solid lead in the battery which form the two electrodes. The negative electrode (anode) is made from pure lead (Pb) while the positive electrode (cathode) is made from lead dioxide (PbO2). It is grave to remember that lead has an oxidation number of 0, while lead dioxide is +4, as it is the change in these numbers due to the reaction in the cells that will cause a flow of electricity.The acid in the battery forms the electrolyte. This acid is the compound sulfuric Acid (H2SO4), which is also mixed with water (H2O). This acid remains in the ionised form of two H+ protons and an SO42- ion. This is due to the fact that Sulfuric Acid will only lose one of its protons when it comes into contact with the water, saving the other for reaction with the lead on either electrode.When the two electrodes are placed into the electrolyte and the circuit is completed, both electrodes will begin to form a coating of lead sulfate (PbSO4) around the original compound. Therefore, we can draw up the half reacti ons that adjust the chemical process in a lead-acid battery.A typical, conventional lead-acid battery consists of a 6V pack, i.e. the battery has 6 cells in it, with each cell having a capacity of 2 Volts (emf is equal to approximately 2.041 V in each cell). The internal resistance depends on the maximum voltage that is currently flowing through the battery. In a fully charged 12.6 Volt lead-acid battery, the internal resistance is about 10 milliohms. This very low resistance results in the high maximum current that the battery can produce. However, unlike the nickel-cadmium battery, it can only produce this current for a very limited amount of time (200 to 300 cycles), after which the current will begin to diminish and internal resistance will begin to increase. The resistance is also affected by the number of cells in the battery, i.e. the more cells, the higher the joint internal resistance. The most common application of the lead-acid battery is the motorcar battery, also known as a lead-acid accumulator. This type of battery (usually 6V or 12V) uses a dynamo to recharge the battery and store energy while the car is turned off, so that it doesnt run flat.The Recycling and Disposal of Battery ComponentsChelsey MoubrayAn electrical battery is a combination of one or more electrochemical cells, used to convert stored chemical energy into electrical energy.Where do you use batteries?Batteries form an essential part of everyday life. As consumers, we make regular use of these electrical units to perform a variety of different things. When speaking about small electronic items, batteries are the most common systems that are used to power things such as cameras, cellular phones, watches, laptops, remotes, most flashlights and many other household items.Every car is power by an electrical car battery that enables mobility and these batteries are considered one of the most important purposes of batteries. Alkaline batteries are used to power these massive car batt eries as well as radios, carbon-zinc batteries for childrens play toys and torches. Lithium is mainly used in batteries for things such as your camera, a calculator or your watch but sometimes mercury is also used for these mingled items. Mercury is also used for hearing aids, which are also powered by silver and zinc batteries.Batteries are a very important component in our day to day lives. To put it simply, they make everything a lot easier for us. Introducing a whole new spectrum of electronic appliances and equipment, we have easier ways to listen to music, know the time, travel faster and even listen without too much difficulty.To execute these functions we need to choose between two types of batteries that are used today Primary Batteries and Secondary Batteries. A Primary battery is more commonly known as a disposable battery and can be used for portable devices that demand an immediate and direct current when switched on. The advantage for homes is that these batteries are easily accessed but can only be used once and must be thrown away after. The other battery is not only a better option for households but is also a healthier option for the environment*. These Secondary batteries are also know as rechargeable batteries, and must be charged before use. These batteries can be used many times, as they are rechargeable and perform the same job as a Primary battery.In conclusion, we use batteries in many different areas but mainly to power items that are a major part of everyday life. Like we are dependent on our cars and our watches for the time, we are therefore dependent on batteries. They form a large purpose in our lives and must use safely. In order to verify this safety we must learn to dispose of our batteries correctly.How do you dispose of batteries?To begin with, there are few standard procedures that should be followed when dealing with batteries. Never dispose of batteries in a fire source because it is likely that they will explode. Make s ure never to place batteries in a group because if they contain even a small amount of power, when banged together they may release a charge that could result in them catching fire which can have devastating results. When it is apparent that a battery can no longer power its appliance, it must be removed immediately because it may leak. And lastly, never place a battery in a pocket because it may burst and cause another leakage. The first step to the adequate disposal of a battery is to place a weak battery in some sort of container until you can correctly recycle it.Every battery is now considered to be hazardous waste. Because they contain very toxic metals such as Mercury, they have been classified as un fitted to be thrown away as standard municipal solid waste. Batteries are not to be placed in communal dumps because there is a chance that these toxic metals can have a serious and perpetual effect on the surrounding environment.*Some of the batteries that are required to be ac curately disposed of are batteries that can be found in power tools, mobiles, various monitors, portable lamps, investigative electronic gear, flashlights etc.The new disposal requirement applies to all types and all sizes of batteries, including but not limited to Alkaline, Nickel metal hydride (Ni-MH), Nickel-cadmium (Ni-Cd), silver gray button (Ag), Mercury (Hg), sealed lead acid (Pb), Wet lead acid, Carbon-zinc, and Lithium Ion.There are a number of standard alkaline batteries that are not classified as harmful and can be thrown away as regular household waste but it is recommended for the batteries containing lithium, mercuric, oxide, nickel-cadmium, nickel metal hydride and silver oxide to be recycled. Most recycling areas contain a department for electrical batteries but it is best to contact your municipality to find out where most suitable to go. As the renowned Duracell battery company stated, Proven cost-effective and environmentally safe recycling processes are not yet universally available for alkaline batteries. Some communities offer recycling or collections of alkaline batteries- contact your local government for disposal practices in your area.Impact of BatteriesWhat is the impact of batteries on humankind? clear there is both an adamant negative and positive impact of batteries on humankind. The basic positive impact is that everything is a lot easier for humans. There are numerous activities that have been made possible for us through the creation of batteries. For exampleCar Batteries Car batteries have made mobility possible. Without this invention we would never be able to depend on such a reliable, easily accessible and quick form of transport. The introduction of automobiles has made a hugely positive impact on human kind.Monitors There are various types of monitors that are used today, one of the most common being the standard hospital heart monitor. These monitors are responsible for keeping people alive. As a source of education an d examination, these have formed an incredibly vital part of the medical world.Watches Without batteries we would never have portable clocks that can be used to easily access the time. Although not a compulsory essential, watches have been said to be one of the most important concepts on a small scale.As mentioned in the previous section, there are hundreds of other manufactured electronic creations that have been made possible by the introduction of batteries. These creations have formed a vital part in humankind development over the last few decades. Without the establishment of batteries, the mechanical world would never have progressed and reached the critical level that it has reached. Enabling huge scientific breakthroughs and discoveries, batteries have formed the foundation blocks of our society and continue to enable extensive studies and research.Although batteries have facilitated a large range of discoveries and activities, they also have a negative impact on humankind. One of the most prominent negative impacts is the dependency on electronic appliances. As a embryonic world we have developed over many centuries, beginning with a very rural state and growth into a mechanical industrial world highly dependent of technology. Included in this technology is the battery. As said before, as one of the foundation blocks of society, communities have become largely dependent on batteries for necessities such as transportation and work, but also less essential activities including entertainment and leisure. As a world(prenominal) community we have survived in circumstances far more extreme than today without the help of batteries and futuristic technology, so it is evident that although accommodating, batteries can be considered un

Pressure Relief Valves :: essays research papers

PRESSURE RELIEF VALVESChemical Engineering Lab IQuestion Discuss the importance of Relief Valves in the unit operations in detail, and give the design criteria/ parameters/ models available equations in the literature. Support your work by giving a typical example from the literature.INTRODUCTIONSince the inception of pressurized systems to produce and transmit energy, it has been a constant goal to find safe, dependable means of relieving pressure. The simple, inexpensive, forswear loaded support valves has been manufactured for over a hundred and fifty years, performing its job with varying degrees of reliability over that time period. In the Unites States alone, tympanum explosions caused a significant loss of life reaching a peak with 400 such explosions in 1904. With the adoption of the ASME pressure sensation and Vessel Code in 1911, boiler explosions declined to where, after 1973 they be non-existent. Over the same period, operating pressures for most systems were increa sed, in the case of boiler pressures increases were from 200 to 3000 psi and above.Pressure relief valves are used to safely contain pressurized gases and liquids. Throughout the years there has been an increased demand for safety in industrial and other related operating practices. These valves are one of the many devices that have been created in conjunction with standardized design and operating practices, for the provision of this very protection. In the past, vessels that now would obviously require relief valves were heated often resulting in drastic increase in pressure within the vessel. This resulted in an extremely dangerous outcome physically for all the parties involved. Pressure valves may be classified into two main categories namely reclosing and non-reclosing. Reclosing devices are the more common of these two groups. They are designed in such a manner that they reclose securely once safe pressure levels have been restored. The second type, the non-reclosing pressur e valve, does not reclose nor vent all the fluid built up, for example liquid plugs.Pressure relief valves are relatively simple pieces of equipment. The operation of these devices involves a spring-loaded discus resting on a seat. When the pressure is low the force on the disk is less than the spring force on the disk and the valve remains closed. The pressure force increases causing a drop in the force that seals the disk on the seat. Once the valve is raised a larger disk area is available for the fluid to flow through providing a lifting force which is directly correlated.

The Queer Prison Abolitionist Movement Essay -- Prison Abolitionist, I

It would be misguided to discuss queer prison abolitionist movements without primary thoroughly examining the place of the prison system in the neoliberal imperial project of enemy production (both inside and outside the boundaries of the state). The contemporaneous production of exterior and interior enemies (terrorists and criminals respectively), movement toward and legislation for ostensible (and, importantly, homonormative) queer equality, the criminalization of radical activism through increased surveillance, torture, disappearance, and imprisonment, and the exponential growth in the transnationally funded prison system is symptomatic of what, in the article Intimate Investments, Anna M. Agathangelou, M. Daniel Bassichis, and Tamara L. Spira deem the imperial project(s) of promise and nonpromise (Agathangelou, Bassichis, and Spira 120). Agathangelou, Bassichis, and Spira argue that, inherently a part of empires promises to some groups of safety and inclusion body in globa l capitalism is a process of new(prenominal)ing by which other groups are constructed as enemy others, and by which yet other groups are rendered other Others whose life and death do not even merit mention or attention (123). At the heart of this process lies the imperialist drive to micturate and protect the new world order via what M. Jacqui Alexander deems the process of incorporation and quarantining (Alexander qtd. in Agathangelou, Bassichis, and Spira 127). This process serves the imperialist ends of militarization by constructing enemies which must be contained and/or killed it also provides a backdrop against which newly legitimized homonormative queer identities can be conceptualized. In other words, by creating classes of racially sexualized... ...plex. Eric A. Stanley and Nat Smith. 1st ed. Oakland AK Press, 2011. 267-79. Print.Girshick, Lori.
