The History of the Hygrometer

The History of the Hygrometer A hygrometer is an instrument used to measure the moisture content – that is, the humidity –  of air or any other gas. The hygrometer is a device that has had many incarnations. Leonardo da Vinci built the first crude hygrometer in the 1400s. Francesco Folli invented a more practical hygrometer in 1664.In 1783, Swiss physicist and geologist, Horace Bà ©nà ©dict de Saussure built the first hygrometer using a human hair to measure humidity. These are called mechanical hygrometers, based on the principle that organic substances (human hair) contract and expand in response to the relative humidity. The contraction and expansion move a needle gauge. Dry and Wet-Bulb Psychrometer The best-known type of hygrometer is the dry and wet-bulb psychrometer, best described as two mercury thermometers, one with a wetted base, one with a dry base. The water from the wet base evaporates and absorbs heat, causing the thermometer reading to drop. Using a calculation table, the reading from the dry thermometer and the reading drop from the wet thermometer are used to determine the relative humidity. While the term â€Å"psychrometer† was coined by a German Ernst Ferdinand August, 19th-century physicist Sir John Leslie (1776-1832) is often credited with actually inventing the device.   Some hygrometers use the measurements of changes in electrical resistance, using a thin piece of lithium chloride or other semiconductive material and measuring the resistance, which is affected by humidity. Other Hygrometer Inventors Robert Hooke: A 17th century contemporary of Sir Isaac Newton invented or improved a number of meteorological instruments such as the barometer and the anemometer. His hygrometer, regarded as the first mechanical hygrometer, used the husk of oat grain, which he noted curled and uncurled depending on the humidity of the air. Hooke’s other inventions include the universal joint, an early prototype of the respirator, the anchor escapement and the balance spring, which made more accurate clocks possible. Most famously, however, he was the first to discover cells.   John Frederic Daniell:  In 1820, British chemist and meteorologist, John Frederic invented a dew-point hygrometer, which came into widespread use to measure the temperature at which moist air reaches a saturation point. Daniel is best known for inventing the Daniell cell, an improvement over the voltaic cell used in the early history of battery development.

M_Q_2 - Essay Example The culture of an organization shows the way the employees deal and interact with each other while performing their job related tasks. I believe that the culture of an organization develops with time when the employees, managers, and all governing bodies of an organization work with full commitment shaping a positive organizational culture. In my view, the culture of an organization really improves the performance and productivity of an organization. A strong organizational culture unites the employees and motivates them to work efficiently and professionally towards their goals. Organizational culture includes such elements, which play a vital role in making a company reach desired sets of goals and objectives in an effective way. Some of the most influencing tasks, which organizational culture performs, include determining the organization’s effectiveness and capacity, putting energy and momentum in the employees in order to ensure organization’s success, injecting se nse of responsibility in the employees, and making the employees work efficiently towards achievement of desired goals and objectives. These were some of those roles, which culture plays in making an organization achieve desired goals and objective effectively and efficiently. Answer: No: 2 Culture of an organization is one of the main drivers of organizational performance and it can definitely be used to increase performance. Daniels A. and Daniels J. found that managers need to evaluate performances of the employees and the organizations in order to implement positive changes. It depends on the managers of an organization to motivate and encourage employees to work with full dedication and commitment. The dedication and commitment shown by the employees of a company towards their job responsibilities shape the culture of the company. If the employees carry out their job related tasks efficiently, it creates an enthusiastic and motivated culture of the organization, which positivel y affects the new employees who come and join the company. From here, the transition process starts where impact of employees’ performance on the culture of an organization shifts towards impact of organizational culture on the performance of new employees. Once the employees succeed in shaping a work-oriented culture in an organization, it plays a considerable role in motivating new employees to work hard for the company. A new employee is not very much aware of the culture of the company where he/she gets a job. When that employee starts working for the company, he/she observes the overall workplace culture of the company and shapes his/her job behavior according to that culture. If a company will have work-oriented culture enriched with the elements of motivation, innovation, and workplace ethics, it will make a positive impact on the new employees and will make them work hard to achieve the company’s goals and objectives. Therefore, we can say that strong culture o f an organization not only increases employees’ productivity but also increases the overall organizational performance. Answer: No: 3 As a senior leader, I will like to change the culture of the organization by integrating the elements of hard work, commitment, dedication, and enthusiasm in the existing culture of the organization. I believe that when employees feel like owning the company, they work with more commitment in order to make their company reach heights of success in any specific market. If a company injects the sense of

Supply Chain Management - Essay Example These end users regard companies who refuse to abide by the regulations as irresponsible and try to avoid them. This means that should all factors in the supply chain process be put in place but common actions on abiding by regulations that borders on the wellbeing of people and the environment be ignored, there is no way customers would accept or patronise products from such irresponsible companies (Bowman, 1997). This way, the core motifs of companies in going into production would totally be defeated. It is in light of this that corporate organisations and companies have always taken steps to be accepted in the face of customers and the general public as corporately responsible. To achieve such tags of corporate responsibility, companies take a number of corporate responses to address specific issues. In the following sections, three companies and how they have taken specific corporate responses to address certain issues that borders on the environment and the growing challenges o f global supply chain have been addressed. GlaxoSmithKline As a company, GlaxoSmithKline has taken a number of initiatives that are based on the principles and core values of supply chain management: particularly, supply chain business process integration to address a number of social and environmental issues (Lambert, 2008, p.15). Three of these and how the company facilitated change in the given directions have been discussed below. Environmental degradation As a pharmaceutical company, GlaxoSmithKline has been faced with several issues that concerns environmental degradation. Environmental degradation has been explained as an act that deliberately or unintentionally causes damage to the environment (Burgess, 1998). Such practices have bordered the company because it depends on some raw materials that are acquired directly from undertaking environmentally threatening acts like the cutting down of trees. In the course of manufacturing also, there is the release of large volumes of waste fumes into the environment. Through the supply chain management practice of manufacturing flow management, the company has been able to ensure that what could otherwise had been serious damage to the environment has been controlled. According to Goldsby (2003), manufacturing flow management â€Å"includes all activities necessary to move products through the plants and to obtain, implement, and manage manufacturing flexibility in the supply chain (p. 23)†. Specifically, the company has been engaged in the purchase of production plants that have been designed to internally recycle waste fumes for the generation of power. This way, waste fumes are not thrown into the open atmosphere. Rising energy and materials prices Recently global events including outbreak of wars and political uprising in major oil producing countries have led to rising price of crude on the world market. This has apparently led to increase in the cost of energy. Most commonly, increase in prices of e nergy leads to increase in prices of raw materials (Copacino, 1998, p.31). This is because of the high cost of transportation that increase in the prices of energy brings about. For GlaxoSmithKline as a company, steps have been taken with reference to the order demand

The Financial Enviroment of Healthcare Organizations Essay

The Financial Enviroment of Healthcare Organizations - Essay Example Sharing financial information with the employees of a business should be done by corporations even if they are not required do so such as private firms. A lot of different aspects of the financial performance of the firm should be released. The four major financial statements of a company are the income statement, balance sheet, statement of retained earnings, and the statement of cash flow (Garrison & Noreen, 2002). These statements are prepared upon completion of the accounting cycle. An employee of the firm can perform an evaluation of the financial performance of the company using ratio analysis if he is given the financial statements of the firm. The five categories of ratio analysis are liquidity, asset turnover, profitability, market, and financial leverage. Analyzing the cost structure and expenses of a firm is important for an employee. Companies whose cost structures are too high are at risk of downsizing or closing its facilities (Capella, 2008). The income statement shows the expense accounts of an organization. Profits are obtained by subtracting total expenses from the revenues of a firm. Costs are classified as fixed or variable costs. Fixed costs do not change over time, while variable costs change as a company increases or decreases production output (Thomason, 2014). An important accounting metric that stakeholder groups such as employees need to understand and be informed about is the breakeven point. The breakeven point is the amount of sales that a company needs to generate to cover all its fixed and variable costs. Profit at the breakeven point is cero. The formula to calculate the breakeven point in units sold is fixed expenses divided by unit contribution margin. Unit contribution margin is calculated dividing sales price minus variable cost per unit. The employees must know whether its company is breaking even because the solvency of the firm is dependent on it. Controlling the inventory of a business is

Strategies to Reduce Water Scarcity

Strategies to Reduce Water Scarcity Water Woes- how can you reduce fresh water scarcity in a country? Abstract The essay can be divided into three parts. First of all, it will introduce the fresh scarcity in Israel. secondly, it will discuss some questions and methods for the water scarcity in Israel. finally, I will give my own opinion and image what will the water scarcity be in the future in Israel. Introduction The essay is going to introduce that how to reduce fresh water scarcity in Israel. The water is very lacking in this country. Not only for human, but also for the animals and plants live this country. In the other hand, the government of Israel has tried many methods to reduce the fresh water scarcity. Even they had the war for the water. But still is powerless on this way. Per capita water for the people of Israel is only 150 MCM. But in fact the capita water they used have reached 290 MCM. Otherwise, because of the pollution from the industries, the water chemistry in local river is not good. At all, the best way to reduce the water scarcity in Israel is to combine many methods like artificial rainfall, the implementation of each person to save water with reward system, the use of recycled water to solve this problem. Methodology The plan for achieving research purpose for 3 stages. They are first collect all the methods that can reduce the fresh water scarcity. Next, compare these methods and get the finally few methods which are suitable for Israel. Finally, image to put these methods to Israel and compare the data from Israel. Check whether they are suitable for Israel. The most of the information I got was form Bing. Because this website is relatively large and reliable. Furthermore, I chose the resource as possible which has the author and the date of creation. In addition, I deliberately chose the information on the websites which have different data that I want to use as the sources I used. And I think the name of website which is socialistworker.org is the best website I found. Because it got a lot of useful information. For example, it introduces the terrain of Israel, the history of the methods which the government ever used before and so on. Findings There are two issues are serious about water scarcity in Israel. One issue is the per capita water for the people who lives in Israel uses too much. In the front of the essay, mentioned the per capita water for the people of Israel is only 150 MCM. But they did not save to use water. So the result of the usage amount is far beyond the standard. If Israel wants to reduce the fresh water scarcity. They must overcome this difficulty. I think that the government in Israel can give some policies. For example, if someone save to use water reach to some standard. He can get some money like this. Another issue is because of about 80% of water in Israel has already reused many times. The quality of the water is not good. In my opinion, Israel must find the other water resource. We all know, Israel face two seas. They can make full use of this condition. In my view, they need to vigorously develop the technology that can convert seawater into fresh water. Although the cost is very high. But if they solved the water scarcity problem, they can get more money return. Now the population of Israel is about 8 million 500 thousand. And the area of Israel is about 25740 square kilometers. Compare Israel with china. We all know that there are a lot of people in china and the per capita water for per Chinese is very low. But the per capita water for Israel people are only 1/4 of chinas per capita water. The chart shows the proportionof the water resources situation in Israel. The data came from http://www.jewishvirtuallibrary.org/jsource/brief/Water.html and http://www.jewishvirtuallibrary.org/jsource/History/scarcity.html Discussion In this section, this essay will evaluate the findings in light of the hypothesis firstly. Secondly, discuss the proposed solution. I think the content I wrote in the findings section is more clearly provides the solution. Then, combine the pie graph in the findings section and think about my proposed solution that is find other water resource. Form the graph, we can know that most of the fresh water of Israel is from seawater. This means my proposed solution is working. On the other hand, the problem about the per capita water for the Israel people. This is the most important problem actually. In this issue, the government of Israel has ruled that 100 liters of water per capita per day on average for the people in Israel. Expect the Palestinians. They can only get 70 liters of water per capita per day on average. Furthermore, in some areas, the figure is as low as 20 liters per day for Palestinians. By contrast, Israelis consume up to 300 liters per capita per day. That is unfair. I n addition, the local people in Israel are using too much water. They still not pay attention to the importance of water conservation. Although the government always propagandas water conservation. we can do a calculation. Lets say one local people in Israel use 300 liters per day and expect the Palestinians firstly. There are about 8 million 500 thousand people. It is amount of 255 million liters. It is a big number for a country which is lacking of the water. Conclusions and Recommendations In conclusion, the proposed solution that the essay mentioned is suitable for Israel after the comparison of the data and in light of the background of Israel. but actually the government of Israel is doing the solution that the essay given. Just not enough for reach the point that can solve the water scarcity. So, whether can solve the water scarcity in Israel fundamentally is depend on the per capita water the Israel people using. On the other hand, if the government of Israel limits the consume of water for Israel people compulsory too much. They will be unhappy and remonstrant absolutely. So, government must give some other benefits to instead of this. Finally, according to my research, Israel also use many other methods to get fresh water. One of them is artificial rainfall. This is the easiest way. Israel is the famous country that has the lowest natural resources. So, in my opinion, they should use many methods at the same time for saving water. Like use artificial rainfall, t he implementation of each person to save water with reward system, the use of recycled water to solve this problem.

Stereotypes in Our Day Out Essay -- Our Day Out Willy Russell Stereoty

Stereotypes in Our Day Out Can Willy Russell be accused of using stereotypes as a means of putting his opinions forward? Throughout the play; ‘Our Day Out’, written by Willy Russell, there is a constant use of stereotypes portrayed in the characters. Stereotypes are standardised characters or a fixed idea of something. Willy Russell used stereotyping as an effective way of putting his opinions forward because he could develop his initial ideas for characters to raise awareness of what Liverpool was like in the 1970s. In my opinion Willy Russell wanted to show the general life of many children in Liverpool in the 1970s and also to show that stereotypes create false views of certain people and are harmful in general. In the text, the main characters are children and teachers in 1970S Liverpool. Teachers are often stereotyped anyway; people presume that they are strict and disliked or the opposite. This contrast is shown with the two characters Mr Briggs, who is rather strict and Mrs Kay who is not. In the play Mr Briggs is often shouting at the children or telling them off: â€Å"Never mind what for, just do what you’re told, lad.† This emphasises the point that he is stern. There are no points in the text where Mrs Kay has this attitude directly towards the children. The children in the play are also stereotyped because they live in a rough area and don’t have many opportunities- because of the fact that they live in Liverpool. In the play the children swear and steal, suggesting that they are somewhat deprived; they break the law and are impolite as they don’t know any better and have been brought up in a way which it is natural to do so. They are underprivileged as when they encounter animals at the ... ... he is very caring. I feel that Willy Russell uses stereotypes as a means of putting his opinions forward because stereotypes are so powerful and would make his opinions clear without directly linking them to him. They also make the text more understandable for the reader and intended audience. As a final point, I feel that Willy Russell uses stereotypes to no only make his opinions known but also to show that stereotypes are very powerful and maybe even deter people from using them as they can limit a persons mind, if, for example a child had been told they wouldn’t get a good job it may stop them from trying. Therefore Willy Russell does use stereotypes to put forward his opinions and may also use them to make people think carefully before they make presumptions about someone because of their age, race, job, wealth, beliefs or even their background.

Drama and audience Essay

Reverend Hale’s role in the play is to originally cure of find the illness of Betty. But instead he is described as â€Å"stiring the witchcraft cauldron that is brewing in Salem Village†. Arthur Miller uses words and phrases such as; narrowing his eyes, holding up his hands, surprised, quickly, grasping, rising exhilaration, kindly ect. This describes Reverend Hale’s character well, as he is a do-gooder within the village. Miller emphasises his importance, by making his character loud, expressive yet good hearted. He makes sure the audience is aware of Hale’s importance, by making him a figure to look up to, someone that people can see God in, and by making people confess to him he is showing the power he has. Parris’s status within the community should be an example to others, but is slowly withering as the accusations of witchcraft within his village and family drag him down. The farmers Proctor, Putnam and Giles, are all below Parris in society. They are the main male characters in the play and because Parris is higher up in society, he remains the loneliest out of the four; this is significant as he knows he cannot cope with all the stress as a single parent and guardian, and a reverend Salem relies on. As previously written, Hale was confessed to by Tituba. She confessed to seeing Satin towards the end of Act 1. Her confession was dramatic and Miller emphasised this well by using language such as; weeps, sobbing in terror, falls to her knees, frightened, suddenly bursting out, in a fury ect. Influenced by the forgiveness given to Tituba, this is significant as she is setting an example and giving ideas to the girls. Abigail copies calling out accusations, as assumed and for example she shouts; â€Å"I saw Sarah Good with the devil! † ect. Scared and confused girls followed in Abigail’s actions and began calling out accusations as well. The girls soon figure that lying, pretending and accusing others, will take the limelight from them and they will soon be seen as victims and witnesses of Satin. In conclusion, Arthur Miller’s stage directions in the play, The Crucible, create drama and inform the audience about the nature of the society in Salem. He uses them effectively to create instant excitement and effect as well as defining the characters in detail. The characters are however Millers own creation and through his direction they add drama to the story. The language used in the play highlights the lack of communication in its simplicity and distances itself from the twenty first century. The people in Salem lived solely by their religion and were unable to accept anything that may defy their beliefs. It also showed the lies and deceit that people created to protect their own name and standing in society. Arthur Miller has managed to skilfully tell the story according to historic facts whilst adding his own portrayal of characters to attract audiences today.
