Real-World Green Chemistry Examples

Reals Green chemistry seeks to develop products and processes that are kind to the environment. This can involve reducing the waste a process creates, using renewable materials, lessening the energy required to form a product, etc. The US Environmental Protection Agency (EPA) sponsors an annual challenge for the most innovative green chemistry inventions, plus you can find examples of green chemistry in many of the products you buy and use. Here are some interesting sustainable chemistry achievements: Biodegradable Plastics Plastics being developed from eco-friendly renewable sources, plus some modern plastics are biodegradable. The combination of innovations reduces our dependence on petroleum products, protects humans and wildlife from undesirable chemicals in old plastics, and reduces waste and impact on the environment. Scientists at  NatureWorks  of Minnetonka, Minnesota, makes food containers from a polymer called polylactic acid, made using  microorganisms to convert cornstarch into a resin. The resulting polymer is used to replace rigid petroleum-based plastic used in yogurt containers and water bottles. Advances in Medicine Pharmaceuticals are expensive to produce in part because of the complicated and exacting synthesis mechanisms required to produce some drugs. Green chemistry seeks to streamline production processes, reduce the environmental impact of drugs and their metabolites, and minimize toxic chemicals used in reactions. Professor Yi Tang, of the University of California,  devised an improved  synthesis process to make  Zocor ®, which is the brand name for  the drug, Simvastatin, used to treat high cholesterol. The previous process used hazardous chemicals and released a large volume of toxic waste. Professor Tangs process uses  an engineered enzyme and a low-cost feedstock. The company Codexis, then took the mechanism and  optimized the enzyme and synthesis process so the drug could be manufactured more safely, less expensively, and with less of an environmental impact. Research and Development Scientific research employs a number of techniques that use hazardous chemicals and release waste into the environment. New greener processes keep research and tech on track while making it safer, cheaper, and less wasteful. Life Technologies  developed a three-step, one-pot synthesis method for polymerase chain reaction (PCR), used in genetic testing. The new process is more efficient, consuming  up to 95 percent less organic solvent and releasing up to 65 percent less waste compared with the conventional protocol. Using the new process, Life Technologies  eliminates about  1.5 million pounds of hazardous waste each year. Paint and Pigment Chemistry Green paints go way beyond eliminating lead from formulations! Modern paints reduce toxic chemicals released as paints dry, substitute safer pigments for some poisonous colors, and reduce toxins when the paint is removed. Procter Gamble and Cook Composites and Polymers formulated a soya oil and sugar mixture to replace petroleum-derived paint resins and solvents. Formulations using the mixture release 50% fewer hazardous volatile compounds.Sherwin-Williams created water-based acrylic alkyd paints that contain low levels of volatile organic compounds  (VOCs). The acrylic paint is made from a mixture of acrylics, soybean oil, and recycled PET bottles. Manufacturing Many of the processes used to make products rely on toxic chemicals or could be streamlined to reduce the use of resources and release of waste. Green chemistry seeks to develop new processes and improve conventional production methods. Faraday has developed a plating process to make high-performance chrome coatings from trivalent chromium instead of highly toxic hexavalent chromium.

Toilet Paper Icebreaker Games

Toilet Paper Icebreaker Games Social and business gatherings can be awkward at first, especially if participants dont know each other. Icebreaker games can help a host solve that problem and motivate guests  to break through their initial social fears, leading to a productive meeting or event. Try this toilet paper game to grease the social wheels. Grab a Roll Youll need little preparation. Just grab a full roll of toilet paper from the bathroom, and then: Take the roll of toilet paper, pull off several squares before handing it to another person and asking him to do the same.Continue this until all guests have grabbed a few pieces.Once everyone in the room has taken some toilet paper, each person counts the number of squares that she has grabbed and then tells everyone that number things about herself.For example, if someone has three squares, he would share three things about himself. Give an Example If you have a particularly shy group, spark the discussion with an example, suggests  Beat by Beat, a website focusing on drama and theater. The website gives the following example: If Isabel took five sheets, then, she might say: I like to dance.My favorite color is purple.I have a dog named Sammy.This summer I went to Hawaii.I’m really afraid of snakes. Beat by Beat says that you will also learn about participants personalities based on who took a greater number of sheets compared to those who tore off only a few. Extending the Game Leadership Geeks, a website focusing on leadership skills and team building, suggests extending this seemingly simple game to foster team-building, work habits, and social skills. After all of the  participants have torn off a few pieces of toilet paper and you have explained the rules of the game, notes the website: You may hear laughter and groaning when some realize they took too many squares.End the session by sharing a humorous moral: â€Å"Sometimes excess can be bad for you!†Ask participants: How many of you took more than what you knew you would need just in case? What does that say about your approach to life in general?What are some interesting things you have learned about your fellow participants? You can dissolve uncomfortable distinctions between those hoarding a large number of pieces and those who only grabbed two or three. Afterward, have everyone throw their sheets into the center, says Beat by Beat. This represents all the new information we now know about each other. Its amazing how much social traction you can gain with a simple bathroom supply. And, regardless of how many sheets participants tore off, youre likely to have plenty of paper left on the roll for your next event.

The assessment should look at the basic human resource functions including the management of performance, recognition and reward, and compensation. The assessment should also involve the employee handbook and his or her policies, the workforce planning, development and training, work climate and employee engagements among other functions. It should be by interviewing the staffs, using questionnaires to collect data, review of relevant documentation, compiling the data, making a written report, and making recommendations. The assessments above are for managers and employees get to know the impact the organization will have if they pursue the organizational goals in performance.

Such also applies the case 5 wh ere the company should train employees on the use of office equipments and infrastructure. Question One (b). If the HR practitioners come to the attention to be lacking in strategic skills, the management should come up with incentives that will give such HR practitioners to strive to attain the set standards of the organization. One of the incentives that will give evidence in the effectiveness of the HR practitioners is the recognition and reward, and the compensation or promotion. In addition, the management should demonstrate evidence by offering training and development in the areas the practitioners lack in skills, and devising some plans of employee engagements in order to improve the sharing of skills amongst the workforce. This will also improve the work climate as conducive. The incentives will provide employees with the necessary skills that the organization requires, and for the organization competence. It enables them also to improve in their personal skills that will b e of advantage to them in wherever they purpose to pursue their dreams. A good example from the case studies involves the OZ international, whereby the company is under embroil in employee low morale. This is significant in demonstrating that the employees lack some strategic skills to propel the goals of the company. Therefore, the management should come up with training and development incentives, including coming with incentives such as rewards in recognitions of their efforts in performance. The management should also provide training to the employees concerning the several laws that they might violate if they take should actions like firing the old employees, which in any case will bring negative implications to the company. Question Two. Appraising and Managing Employee Performance This involves the systematic and periodic process in which the assessment takes place in each employee’s performance and efficiency. This is in relation to some pre-established organizationâ €™s goals and criteria. It may also involve the assessing such aspects as organization’s citizenship behavior, strengths and weaknesses, accomplishments, the possibility of future improvements among other aspects. Some of the methods that are in use in the collection of the data include the objective productions, judgmental evaluation

FYY_SAT_E1 Essay Example | Topics and Well Written Essays - 500 words

FYY_SAT_E1 - Essay Example In order to make the children grow up into responsible and considerate adults, it is imperative that they are shown the world in its true colors right from the very early years of life. Concepts developed in the childhood become stronger later. In the childhood, movies and plays based on myths are children’s favorite. But as they grow up, they tend to loose their association with such movies and plays because they become more practical in their approach towards the world. As grown-ups, they know the world too well to believe in the fantasies portrayed by childish movies and plays. Same holds true for fairy tales. Tales like the Little Red Riding Hood or The Beauty & The Beast used to be my all-time-favorite books when I was a child because there used to be morals at the end of the story. But now they and other stories like them do not at all attract me because as an adult, I would rather read stuff that would increase the knowledge I would need in my everyday life, and not the good-for-nothing fairy tales. History is my favorite subject. Books on such subjects let me know my past better. It is essential for me to know my history in order to learn the reality.

Lucy vs. Zehmer Essay Example | Topics and Well Written Essays - 1250 words

Lucy vs. Zehmer - Essay Example The instrument the Lucys were seeking to enforce stated: â€Å"We hereby agree to sell to W.O. Lucy the Ferguson Farm complete for $50,000, title satisfactory to buyer.† It was written by A.H. Zehmer, and was duly signed by both A.H. and I.S. Zehmer. The defense of A.H. Zehmer was that he considered the offer of Lucy to purchase Ferguson as a joke, and at the time they signed the document both of the respondents were drunk. Zehmer also stated that while he did write the document, to him it was more of a response to a dare, as he did not believe that Lucy could afford $50,000, something he outrightly told the latter. In fact, although Zehmer wrote the contract, he did not deliver it, but Lucy picked it up, read it and put it in his pocket. At this point, Lucy offered $5 earnest money to seal the contract, but realizing he was serious, Zehmer refused to accept the money and instead told Lucy that had no intentions to sell Ferguson. On the other hand, Lucy contended that the sale was a done deal. He argued that at no time did he believe Zehmer to be joking. When Zehmer mentioned that Lucy would not be able to afford his price, Lucy assured him that he could. This was the reason Lucy immediately thereafter asked the help of his brother who agreed to share interests in the purchase. The lower court decided that Lucy had not proven his right to specific performance, and the case was dismissed. ... However, if the contract remains valid, then the Lucys are entitled to its specific performance. 3. The court's decision on those issues The Supreme Court of Virginia ruled that a valid contract had been created when the Zehmers set their signatures to the instrument, creating an obligation on either side to meet its terms as contained in the document. The claim of Zehmer that he was merely drunk, and at the same time only joking (i.e., did not really intend to sell), is not sufficient to invalidate the existing contract. The complainants are entitled to the specific performance of the contested contract. The decision of the lower court is therefore reversed, and the case is remanded. 4. The rationale the court used in reaching those decisions The Supreme Court decided that Zehmer’s contention that he did not really intend to offer his property for sale does not hold water. It is true that normally, the law of contracts requires that the parties to the contract mutually consen ted to it. However, given certain cases such as this one, it is not so important for the parties to mentally agree to the forming of the contract; what is important is that the acts and words of one of the parties convey the reasonable meaning of such intention to the other party, that is, that the parties appeared serious in their intent to transact (Patterson, p. 74). A binding contract of sale therefore existed between the two parties, whether or not the response of the Zehmers was serious or in jest, because one party (Lucy) made a serious offer, and took their response to be likewise a serious answer to his offer. â€Å"Intentions of the parties to a contract are determined by a reasonable interpretation of their manifest conduct and expression.

HYPNOTHERAPY & NEURO LINGUISTIC PROGRAMMING Essay - 1

HYPNOTHERAPY & NEURO LINGUISTIC PROGRAMMING - Essay Example Therefore, all the suggestions are entered to the subconscious without conscious intervention. Once conscious faculties are sure that monotonous stimuli unlikely to endanger their subject, they become complacent and irresponsible. With attention gone there can be no conscious intervention which leads to the state of conscious suspension. Conscious faculties are alert and vigilant to check the security or any danger from external stimuli. Therefore, the conscious faculties intervene when suggestions are on their way to the subconscious. To produce monotony to the sense of feeling, the subject should be made very comfortable by reducing all possible external stimuli. The pressure on the subjects body should be released by avoiding any unpleasant sensation commonly known as pins and needles. The subject should be instructed to sit properly without the legs crossed. The room environment should be calm and temperature should be maintained at constant level. If the emotional force generated by thoughts or perceptions is not discharged through appropriate action, the pressure will build up and escape where it finds least barrier. If it is not discharged, building of such a force might lead to destructive level of pressure. Hypnotist displays posters before his performance which claims to possess mysterious hypnotic powers, the power to control minds, and the power to control the actions of others. At the actual show, special stage props, a carefully planned presentation, and the impressive appearance of the hypnotist, all play a part in contributing still further to building up emotion in the audience. In normal situations the emotion is discharged through appropriate action. The builded pressure escapes where it finds least barrier. When the asserting pressure is moderate, feelings such as satisfaction, dislikes etc. are released. It can render the conscious faculties inefficient and incapable of carrying out their normal duties. In our working model of the

Reflection on The Use of Force Essay Example for Free

Reflection on The Use of Force Essay The short story The Use of Force is a story which is narrated by a character, the doctor. The main character is a normal doctor which appreciates his job and is ready to fulfill his duty; to find out what his patients problems are. In the story, he seems to care allot about the childs health. At one point, he gets mad because all his cooperation with the youngster is getting them nowhere. Anger starts to be felt in the doctors cabinet; this is when the patient will have to be forced to get examined by the doctor. The doctor in the story knows how to apprehend patients, he starts out smoothly with the girl, knowing that children usually respond with a good attitude if you are friendly with them. The doctors duty is to know exactly what you are sick of, which the girl, for unknown reasons didnt want to be examined closely. She refused to admit she had a sore throat. The fact that her ignorance could kill her made the doctor insane, he then became more insistent about using physical force to help her out. Even though the doctors effort didnt work, he knew that if he had the full support of her parents, they finally would come to an end with the problem. The doctor enjoyed the feeling of insane anger towards the child; it made him go through the hard struggle of opening the childs mouth. The anger expressed by him was not directly linked to the girl, but to the situation, he did want to help out the ignorant, suffering girl from the sickness she was hiding. The two characters which bring an essence to the main goal of the story are the doctor and the child. The Doctor then finds pleasure in using force in diagnosing the unpleasant child, which happens to cause her pain. The child therefore, still is fighting back and will not abandon her cause. The child creates the turmoil without being conscious, she is being a painful patient and she is not able to tell whether what she does is good or wrong. It shows us that she is probably a spoiled and rebellious girl, who easily stands out when things arent what she wants. The doctor is also part of the undesired situation, he is a key element in the turmoil. He enjoys using force upon  the child to help her out, he wants to prove her she is wrong to act as such. The doctor feels no remorse’s of the actions he took for the child, all he seeks for is satisfaction by proving himself he is helping the young child. The use of force was needed to resolve the situation. It was necessary to have a proper diagnosis of her health to save her. What really came down to the use of force was that the doctor was determined to find out what troubled the parents of the child. It was also that she made him so angry about being stubborn and so hard to handle that he became more and more persistent. To conclude, both of the characters want to win a fight, with misconduct. The doctor is faced with a problem of self discipline and the young girl has a lack of obedience.
