Chemistry Lab Report Conductimetric Sample

Chemistry Lab Report Conductimetric Paper The aim of this experiment it to analyze the solution of Baa(OH)2 of an unknown concentration. In order to obtain the quantitative analysis, the exact amount of a particular compound or element present in sample, two procedures were performed. The first procedure was by conductivities titration and by gravimetric determination. The conductivity was analyzed during the reaction between the sulfuric acid (HOSES) and barium hydroxide (Baa(OH)2). Through the conductivity, the equivalence point can be determined; from there, the concentration of the Baa(OH)2 solution can be found. The final product of the reaction between sulfuric acid and barium hydroxide is insoluble. According to the lab manual, during the reaction, the total number of dissociated ions in solution is greatly reduced as a precipitate is formed. With the Conductivity Probe, the changes in conductivity of the solution will be analyzed. The collection of Baa(OH)2 precipitate, allowing it to dry, and carefully weighing it will allow for the calculations of the amount of barium ion(from original sample) of unknown concentration, which will aid in finding the concentration. These procedures are pendent on gravimetric analysis (the most accurate and reliable procedures). Important requirements for a successful gravimetric analysis include: a pure compound with an identifiable geochemistry, the precipitation reaction must be complete, specificity of precipitation reagent in sample, the solid sample should be a reasonable-sized crystal, and the molecular weight should be reasonable enough for a good weight of the precipitate generated. For the full formation of the precipitate, it will need to be flocculated. The final outcome of this experiment is to handle, isolate, and analyze chemical samples carefully and thoroughly.

Exoskeletons for Human Performance Augmentation

Exoskeletons for Human Performance Augmentation By definition, an exoskeleton is a skeleton on the outside of the body. One example of an exoskeleton is the hard outer covering that makes up the skeleton of many insects. However, today there is a new invention that claims the name of exoskeleton. Exoskeletons for human performance augmentation is a new type of body army being developed for soldiers that will significantly increase their capacity. An exoskeleton will allow you to carry more without feeling the weight, and move faster too. History of Exoskeleton General Electric developed the first exoskeleton device in the 1960s. Called the Hardiman, it was a hydraulic and electrical body suit, however, it was too heavy and bulky to be of military use. Currently, exoskeleton development is being done by DARPA under their Exoskeletons for Human Performance Augmentation Program lead by Dr. John Main. DARPA began phase I of the exoskeleton program in 2001. Phase I contractors included Sarcos Research Corporation, University of California, Berkeley, and the Oak Ridge National Laboratory. DARPA selected two contractors to enter the program’s second phase in 2003, Sarcos Research Corporation and the University of California, Berkeley. The program’s final phase, which began in 2004, is being conducted by the Sarcos Research Corporation and focuses on development of a fast-moving, heavily armored, high-power lower and upper body system. Sarcos Research Corporation The Sarcos exoskeleton being developed for DARPA utilizes a number of technological innovations, including. A combustion-based driver to support advanced hydraulic actuators that produce robotic limb movements with very high strength, speed, bandwidth, and efficiency; and,A control system that allows the operator to move naturally, unencumbered and without additional fatigue, while the exoskeleton carries the payload. Application-specific packages can be attached to the exoskeleton. These packages could include mission-specific supplies, protective outer coverings capable of operation in extreme threat and weather conditions, various electronic systems, weapons, or supplies and instrumentation for medical support and surveillance. The exoskeleton could also be used to move material in places inaccessible to vehicles, on board ships, and where forklifts are not available.

Effect of Taxation on the Economy Essay Example | Topics and Well Written Essays - 1750 words

Effect of Taxation on the Economy - Essay Example This also leads to a less desirable allocation of the society's resources, thereby bringing about an additional loss in the overall well being. This loss is often referred to as the excess burden of the tax. It is a measure of the inefficiency of the tax, which is to say that it takes more than 1 of private output resource and income to finance 1 of public expenditure. Estimates predict that the taxes would positively use resources only to a certain extent after which these resources will escape into informal sector and diminish tax growth and efficiency. This paper examines the effects of different types of taxes as well as the tax rates on the economic efficiency of the country. It will first give an overview of the types of taxes that are levied and their relevance after which it will compare the tax revenues and the tax rates. It will be followed by a case study to amplify the effects of taxation on the economy. Taxes are direct and indirect in nature of collection. If the taxes are collected directly from the individuals and organisations on whom they are imposed then we refer to them as direct taxes while the taxes that are collected from person other than the one on whom it is imposed it is referred to as indirect tax. Taxes can be divided into two major categories. ... It is often argued that if the present system of levying income tax is replaced with the broad consumption based tax system it would greatly improve the economic efficiency on many accounts. It would eliminate the influence of taxes on the timing of consumption and it may also subject different sources of income to be included in the tax base and similar tax rates which would have otherwise not come under the tax net. A broader tax base would also help in lowering the overall marginal tax rates hence giving a wider choice to the consumer. (James,2006) The lesser the tax system influences the economic choices of the firms and the consumers the more efficient it will be.Income tax by its nature affects two major house hold decisions. Firstly it reduces the price of current leisure in relation to its current consumption. This induces the households to cut back on their consumption and labor supply and increase the leisure. Secondly by taxing the capital income, the income tax brings dow n the price of current consumption in comparison to the future consumption thus discouraging house holds to save more thereby lowering the investment potential of the economy. (Tuomala 1990) On the other hand the consumption based tax influences only the buying decision of the individuals and the returns to the capital income are left untaxed. To make a tax base broader and more neutral it is imperative to lower marginal tax rates. This way the comprehensive tax will improve the economic efficiency to a large extent. Tax Rates v/s Tax Revenues. Higher tax rates levied by the government equally affects all individuals in the society. The

Film--Fog Of War Essay Example | Topics and Well Written Essays - 500 words

Film--Fog Of War - Essay Example The first pointer involves the role of the U.S in the Vietnam War. McNamara was one of the principal U.S leaders that orchestrated the war which resulted in the deaths of 3 million Vietnamese and 58,000 Americans. In the documentary, 85 year old McNamara (playing himself), speaks about the Congressional resolution that gave credence and legality to the Vietnam War. It was later learnt that the U.S Congress, Kennedy and McNamara himself all wrongly interpreted the torpedo incident in the Gulf of Tonkin, which never took place in the exaggerated fashion it was reported (Petrakis). The second pointer to the film’s theme involves the firebombing of 67 Japanese cities by the U.S in 1945 that killed nearly 1 million Japanese (Turan), including a single event in which about 100,000 Japanese were scorched to death in Tokyo. Colonel Curtis Le May, who directed the military operations, along with McNamara (his assistant at that time), were both convinced that the firebombing would bring about a speedy end to World War II. McNamara supports the decision of LeMay and himself that led to so many horrific Japanese deaths by exemplifying it to one of the 11 lessons he learnt in life, namely, â€Å"In Order to Do Good, You May Have to Engage in Evil† (Petrakis). The last pointer to the documentary’s theme involves the Cuban missile crisis in 1962. Colonel Curtis LeMay and McNamara actively featured in it. This time however, the two leaders managed to pull back inches from the brink of what would have been an outright nuclear war between the U.S and the Soviet Union. Leaders of both superpowers were certain of their individual interpretations of the crisis that did not deserve such certitude, and if it were not for Nikita Khrushev’s backing down and withdrawing Soviet missiles from Cuba, and Kennedy’s decision to take the advice of Tommy Thompson who had an acute insight into

Three Distinct Types Of Enduring Self Philosophy Essay

Three Distinct Types Of Enduring Self Philosophy Essay 1. It is believed that there are three distinct types of enduring self happened to both Stelios and the claimant, judging by the experience they have had using the teletransporter. In Stelios case, despite the fact that he got transported to the Mars and brought back to earth, he claims that he is still the same person as he is before. That said, this has shown that bodily continuity is what makes him the same now and earlier he was being transported to Mars. According to Diotima, the body is what who we really are. If the body changes, it will be still the same you. Just like a house which is vacant and then occupied again over several times, renovations are made in the owners best interest. No matter how much is being added and removed from the house, the house forever remains the same house, the house is the self whereas the occupants and furniture are physical features in a body that changes continually. So, he is having a hard time believe that the claimant is correct. Because a fter he used the teletransporter, he still looks and feels the same. However, on the claimants side, things are world apart from Stelio, memory constitutes a large role in what he had said. According to Locke, he believed that memories are what we really are. Ironically, he actually remembered the process where he got killed and being substituted by a clone. Consequently, thats what drove him into bringing his murder case to the court knowing the teletransporter had killed him. He can recall every single detail in his memory and able to present it to the court. In addition to memory, the enduring self is a soul stated by Descartes is related to the claimant side of story. Looking from the claimants perspective, the teletransporter might design to transport your body to Mars, but the soul is left behind on Earth. The soul feels inadequate without the body, hence the soul feels dead. When his body is transported back to earth, the soul and body is reunited. Again, he felt complete bec ause his soul was reattached to the body but doubted whether it is the same body he carried before. 2. Both of us had the same perception that memory makes the self endure over time. Nevertheless, there is a slightly different interpretation of memory for each of us. In Jia Yiis point of view, Memories are what we really are. How we react to different kinds of situations, how we judge things from our own aspects, our characters. When we were first born, we had no memory. And as we grow, we acquire sweet and bitter memories. As we grow older, we tend to gain experience from the happenings we faced in our daily lives. And with that, the memories influence us. It builds our character. Lets say you are a very cheerful person. But then, one fine day, your parents went crazy and started torturing you since then. Would your character be affected? Im pretty sure it would because the bitter memories you bear in your mind haunt you almost every day. That would make you see things different from the way you see things before. Lets say if a person is brought up in a very happy and cheerful family. Of course this persons character would be a cheerful person. And lets say if a person is brought up in a family where the parents always threw their tantrums at th eir child, that person would of course being a very pessimistic. These characters were built differently because of their memories and experiences they had during their childhood. In Jessicas point of view, without memory, we are just like a program that is shut down and never able to be retrieved back again. A handful of critics might not concur with this concept and stipulated that if we dont remember part of our past, therefore we are not ourselves. I would like to go one step ahead and elaborate further to what they have said. Memory and brain is intricately linked and highly dependent on each other. However, our brain is not capable of storing every information that is present to us, but those that appears happening, outlandish and appears important to us turns a memory memorable. Shortly put, our brain and memory is similar to a filter. Bits of information is filtered and the residues left on the filter are those unforgettable memories. Those that are channeled out from the filter is conceived to be menial by the brain. Take this for an example, I was strolling down a park one day, along the curbs I saw neatly trimmed grasses, flowers that smell like can dy, a man sitting on a beach reading a book. All of a sudden, a stray dog aimlessly chased after me and I eventually got taken over by the dog. Chances are, ten years later, when you happened to bumped into the same park, the first thing that comes to mind is that you remembered being chased by a dog. The rest of the details you experienced earlier didnt crossed your mind. Notwithstanding, we remained the same person as before. For the most part, the memory of the past evokes us into becoming a better person or the other way round depending on how well we extract the lesson from it. All in all, memory is precursor to how to change the way we live and ultimately, choose to character we desire to be. Part B 1. The passage is stating that we humans are nothing more than just a body who doesnt have purpose and meaning in life because in the end, we died and that is that. All our entire lives were fixed at the notion that we humans are unique because of we are rational, conscious, have purpose in life when in fact that is not the case. These abilities that are supposed to be designated at a particular way might not be it is meant to be. From young, these inheritable abilities run in our veins and to reject these unique abilities sounds implausible. Therefore, everybody living in this earth considered to be living a wrong life due to the fact that their abilities arent supposed to work like everybody else does. Who knows the instinct, senses, motivation that we have been told arent what they really are. They are all reducible to only physical body, and only that. That being said, this concept of human are worth nothing propels the Nazis to build the concentration camps and exterminate the h umans. Why the Nazis themselves werent killed was they perceive themselves as beyond the normal human beings. They are superior than the prisoners and believed to have more developed abilities the humans, and above all, invincible. The idea of mass killing the humans is as if they destined to be getting rid of. This truly shows that the Nazis treat human nature as non-human. Basically, we are nothing but objects and materials to them. Due to their perception of this, many human lives were lost. This whole passage is set on the materialists view that human is just a physical entity with no immaterial mind. Also, Charles Darwins theory stated that human nature has no purpose and not unique could be partly linked to this passage. 2. of blood and soil is that humans are just plain body without purpose in life, therefore are meant to be killed. On the other hand, at the desks and in lecture halls of nihilistic scientists and philosophers means that all this problem of mass killing of humans stems from the fact that the philosopher and scientists believe that humans have no value. It was not started from ministry but from education by nihilistic scientists. Thats why not everyone is being influence. Because its not at order, its just lectures and teachings. This triggers the Nazis to build a world of their own and decide to kill those human beings. Part C Jessicas response: 1. No, I could be in the perfect virtual reality machine and not know it No, I cant be sure Im awake No, I cant be sure Im not in the Matrix No, its a real possibility I believe that there is a reality independent of my experience, and that it is a real possibility that we dont have knowledge of this reality. Nevertheless, I believe that it will be possible to answer the skeptics. We will find a way to know were not living in the matrix. You selected the heroic response 2. This activity really intrigued me because for the very first time, it allows me to see reflect about the real world were living in. This activity, too in a way lets me to set things into new perspective and taught me a lesson of learning to sink in and open up to new possibilities although sometimes they contradicts my belief. However, as I was halfway through the activity, I had a funny feeling that this activity was disturbing and intrusive because it pervades my original concept of this world. Before this activity, I already have a vivid picture of what Im going to do in the future. Everything seemed impeccable until this activity came along. To say Im living in matrix sounds absurd, near impossible. This is all because what Im doing in the past or right now worth nothing. After every experience I have been through, be it good or bad, is not genuine, but rather controlled by a ultra-sophisticated machine that inseminate you the experience. In other words, experience is contrive d. Whats more, the judgment, ideas, arguments every human has come up with is all formed by this machine, to create the machine thinks is a more vibrant and livable world. I am merely just a character selected by the machine playing in this game of life. Whats inside you is just instructions and algorithms that is written by the machine and you just simply adhere it. Even our families and friends arent truly our families and friends, they happened to be the same exactly like me, selected by machine. In this case, essence is prior to existence. The essence itself is skillfully structured out by the machine, they have crafted the future for us. Yes, unless science has proven were not living in a matrix, I am convinced we are living in a virtual reality, plugged into a computer without us even noticing we are being plugged. For one, there are never any 100% absolute truth in a single theory. For instance, some researchers might show that exercise will make you lose weight while some ot hers disagree. This is to exemplify that there is never a consensus among us human. To deny the fact we are living in a real world and no such possible as matrix is to suggest that we refuse to open up to any possibilities. Truth is, we cant be entirely sure of everything, but rather everything is unsure and not fully been tapped into. Jia Yiis Response : No, I could be in the perfect virtual reality machine and not know it Yes, I know I am awake. No, I cant be sure Im not inside the matrix. No, Its a real posibility. 2. I believe that there is a reality independent of my experience, and that it is a real posibility that we dont have knowledge of this reality. Nevertheless, I believe that it will be possible to answer the sceptics. We will find a way to know were not living in the Matrix. You selected the heroic response For my opinion, I think this is activity is basically fun. It made me thinks twice of what I am doing now. Somehow, Im having doubts of it. What I did everything for the 19 years of my life, was it worth doing it I even thought that was it worth living in this world Somehow, it also made me thought that, was there another world exist that is greater than the world we living in right now This activity made me thought something that I had never thought before. I dont think I could be living in a virtual world. If I am really being controlled by computers, why created so many negative happenings in my life Why always repeating the same thing again and again and again Why do we cry, laugh or angry? Why would we have doubts in making a decision or a choice? If we are controlled by computers we shouldnt had emotions and doubts. For example, if you know the game of The Sims, well, its about how we build our virtual characters and build their lives. If its for me, I wouldnt create an unhappy life for my virtual characters. Because its painful. No one controls us but ourselves. We make our own decisions and choices.

Personal Leadership Philosophy Essay -- definition of leadership

In developing this idea of what leadership is, I examined what was most important to me in being a leader. Since leadership is such a broad term, this could not be a process whereby I could generalize leadership for everyone. Rather, the task is to determine who I am as a leader. I asked myself, what is it that shapes the vision? What are the factors that comprise a leader, and what makes these things add up to create something larger than ourselves as leaders? Thoughtful reflections on these things lead me to generate the following definition of leadership: Leadership is about more than simply having followers; it is not a title, and it is not achieved by just following a few principles. Leadership is complex, though at its core, it is having the courage to make the right choices – not just the popular ones, engaging others in a vision, and empowering followers to pursue a shared purpose of achieving a positive, lasting impact. My leadership philosophy has been shaped by several factors, the first of which is the knowledge of self. I am a firm believer that until you know yourself first, you are not able to meet your fullest potential as a leader. The greatest relationships exist when each person knows first themselves and what they bring to the table, impacting all leader/follower relationships. The leader approaches the relationship confidently, knowing that the leader and follower can mutually benefit from their interaction. One of the most important things that I have done in terms of my personal development is to identify my core values. Possibly the most critical step to becoming an effective leader is to determine and understand one’s core values. Many of my values are a result of my childhood; however, t... ...d is constantly changing, and to keep up, one must be prepared to take on opportunities that will result in continued growth and learning. Ultimately, these values are all inter†connected. It takes great courage to lead with authenticity and integrity. Integrity inspires service and respect for others. Living authentically and with integrity enables the leader to develop their passions, resulting in a commitment to hard work and dedication, as well as growth and learning. Pushing through the challenges of a full commitment to this lifestyle of leadership requires a sense of humor, and a willingness to re†align one’s life to one’s passions. I think that when we truly commit ourselves to understanding ourselves as leaders, as well as learn to understand our followers and the relationship that exists between leader and follower, there is potential for great change.
