Nitrogen in Tires

There are multiple reasons why nitrogen is preferable to air in automobile tires: Better pressure retention leading to increased fuel economy and improved tire lifespanCooler running temperatures accompanied by less pressure fluctuation with temperature changeLess tendency toward wheel rot Its helpful to review the composition of air. Air is mostly nitrogen (78%), with 21% oxygen, and smaller amounts of carbon dioxide, water vapor, and other gases. The oxygen and water vapor are the molecules that matter. Although you might think oxygen would be a larger molecule than nitrogen because it has a higher mass on the periodic table, elements further along an element period actually have a small atomic radius because of the nature of the electron shell. An oxygen molecule, O2, is smaller than a nitrogen molecule, N2, making it easier for oxygen to migrate through the wall of tires. Tires filled with air deflate more quickly than those filled with pure nitrogen. A 2007 Consumer Reports study compared air-inflated tires and nitrogen-inflated tires to see which lost pressure more quickly and whether the difference was significant. The study compared 31 different automobile models with tires inflated to 30 psi. They followed the tire pressure for a year and found air-filled tires lost an average of 3.5 psi, while nitrogen-filled tires lost an average of 2.2 psi. In other words, air-filled tires leak 1.59 times more quickly than nitrogen-filled tires. The leakage rate varied widely between different brands of tires, so if a manufacturer recommends filling a tire with nitrogen, its best to heed the advice. For example, the BF Goodrich tire in the test lost 7 psi. Tire age also mattered. Presumably, older tires accumulate tiny fractures which make them more leaky with time and wear. Water is another molecule of interest. If you only ever fill up your tires with dry air, the effects of water arent a problem, but not all compressors remove water vapor. Water in tires should not lead to tire rot in modern tires because they are coated with aluminum so they will form aluminum oxide when exposed to water. The oxide layer protects the aluminum from further attack in much the same way chrome protects steel. However, if you are using tires that do not have the coating, water can attack the tire polymer and degrade it. The more common problem is that water vapor leads to pressure fluctuations with temperature. If there is water in your compressed air, it enters the tires. As the tires heat up, the water vaporizes and expands, increasing tire pressure much more significantly than what you see from the expansion of nitrogen and oxygen. As the tire cools, pressure drops appreciably. The changes reduce tire life expectancy and affect fuel economy. Again, the magnitude of the effect likely is influenced by the brand of tire, age of the tire, and how much water you have in your air. The Bottom Line The important thing is to make sure your tires are kept inflated at the proper pressure. This is much more important than whether the tires are inflated with nitrogen or with air. However, if your tires are expensive or you drive under extreme conditions (i.e., at high speeds or with extreme temperature changes over the course of a trip), its worth it to use nitrogen. If you have low pressure but normally fill with nitrogen, its better to add compressed air than wait until you can get nitrogen, but you may see a difference in the behavior of your tire pressure. If there is water in with the air, any problems will likely be lasting, since theres nowhere for the water to go. Air is fine for most tires and preferable for a vehicle youll take to remote locations since compressed air is much more readily available than nitrogen.

The Song of Songs vs. Lady Antebellum’s Our Kind of Love Free Essays

The Song of Songs vs. Lady Antebellum’s â€Å"Our Kind of Love† The excerpts from The Bedford Anthology of World Literature entitled The Song of Songs can correlate to the contemporary love song â€Å"Our Kind of Love† sang by the notorious, award-winning country music group Lady Antebellum. Besides the fact that these two works were written under antithetical circumstances and during distinctly different time periods, they both share many of the same attributes. We will write a custom essay sample on The Song of Songs vs. Lady Antebellum’s Our Kind of Love or any similar topic only for you Order Now Both of these works closely examine the word â€Å"love†, a word that is commonly misused in the present day generation. Furthermore, they both portray the profound, romantic feeling that a woman and a man share when they are both mentally and physically attracted to each other. The Song of Songs, is often misunderstood. When many people first read this poem, they find it hard to believe that this sexual, explicit love poem is found in the Bible. Phrases like, â€Å"do not rouse her† (210. 9), â€Å"your lips drop sweetness like the honeycomb† (213. 11), â€Å"I have stripped off my dress† (214. 3), and â€Å"I am a wall and my breasts are like towers† (218. 0), are present throughout this poem. Many people read these phrases and think of them to be sexual connotations. These phrases are indeed erotic but what most people do not understand is that this poem is meant to show the love that God has created for a male to feel towards a female and a female to feel towards a male when they are in a monogamous relationship. This poem was also intended to be able to be used as lyric al hymn that could be sung. Many songs in today’s culture portray this feeling of love as well. Our Kind of Love† is a country song sang by the country musical group Lady Antebellum. Although, at first many people may not agree, The Song of Songs, a poem that can be found in the Bible, and â€Å"Our Kind of Love†, a song that just recently was produced, share many of the same qualities. The Song of Songs has two main characters: the bride and the bridegroom whom are lovers. The companions are another group of characters in this poem. They are kind of like the narrators of the poem that chime in at certain times. Each of the three characters plays a contrary role in the love poem. In â€Å"Our Kind of Love†, the country group Lady Antebellum, sings about the love shared between a male and a female. In this song, a man and a woman take turns singing about their love for each other. Even though â€Å"Our Kind of Love† is a song, it can also be considered a poem as well. While reading The Song of Songs, one might doubt that it is a poem because many of the lines contained in this poem do not rhyme with each other however, a poem does not always have to rhyme. One might also disagree that a song such as â€Å"Our Kind of Love† can be a poem, but a song was at one time just a poem until it was actually made into a song. When first looking at both the poem and the song together, the stanza in which they are written looks almost identical besides the fact that the song is obviously shorter than the poem. This should be a clue to the readers right away that they are both poems. Another clue that both of these could be poems or songs, is the title of the poem The Song of Songs. The title says it all. â€Å"Our Kind of Love† and The Songs of Songs are both about two people madly in love. In both of these works, the characters both explain their love towards each other. However, the way they express their love for each other is extremely different. This is because of the difference in cultures and time periods. For example, in The Song of Songs the bridegroom describes his bride’s beauty by using a large amount of adjectives: How beautiful you are, my dearest, how beautiful! Your eyes behind your veil are like doves, your hair like a flock of goats streaming down Mount Gilead (212. 1). In â€Å"Our Kind of Love†, the way the male describes to the female her beauty sounds a little bit different than in The Song of Songs. He explains her beauty by using less description: â€Å"You wear your smile like a summer sky / Just shining down on me and you swear your heart is a free bird / On a lazy Sunday afternoon† (Lady Antebellum). Althou gh these two phrases sound completely different, they are both stating the same thing, that they both think their lover’s are beautiful. The first phrase is written more proper, and the second phrase is more straight-forward and to the point, and this is why a great number of people do not realize that even though the language of The Song of Songs and â€Å"Our Kind of Love† is different, a lot of the phrases in both of these works are stating the same or close to the same thing. Another example of the similarity of phrases is when the bride in The Song of Songs explains the type of love her and the bridegroom share and when both the female and the male in â€Å"Our Kind of Love† define the type of love they have together. The bride in The Song of Songs declares her love for the bridegroom: My beloved has gone down to his garden, to the beds where balsam grows, to delight in the garden and to pick the lilies. / I am my beloved’s, and my beloved is mine, he who delights in the lilies (215. 2-3). In comparison to this phrase, the male and female in â€Å"Our Kind of Love† explain their love by singing: â€Å"Just like driving on an open highway / Never knowing what we’re gonna find / Just like two kids, baby, always trying to live it up / Whoa, yeah, that’s out kind of love (Lady Antebellum). The Song of Songs was written during a much more earlier time period than â€Å"Our Kind of Love†. One can tell this by comparing the language that is used in both of these works. â€Å"Our Kind of Love† is a contemporary song that just came out in the year 2010. This song consists of everyday, modern language. It is very easy to understand the plot of this song just by listening to it or reading it through once. In contrast, The Song of Songs was written â€Å"between 350 and 250 B. C. E. † (208). This poem is much more difficult to understand than Lady Antebellum’s song because it uses more proper, precise language. The Songs of Songs may require a little extra attention in order to clearly understand the poem. This is what throws most people off and makes them think these two works are not alike. However, if one actually takes the time to look over The Song of Songs a couple of extra times, then he will see that they are stating the same objective, just using a different way to say it. When first looking at this essay, one might not agree with my idea that Lady Antebellum’s recent record-breaking hit, â€Å"Our Kind of Love† and the biblical love poem, The Song of Songs are alike. They are indeed written from different time periods and from different cultures however, by now one should agree that these two works are more similar than they are dissimilar. They both have two main characters, a male and a female. Both of these works can be cited as poems or sung aloud. Also, they are both profound love poems. Many say that The Song of Songs was created in order to show God’s creation between a man and a woman and the love they share with each other, and that is what both of these works are doing. Even though The Song of Songs is much longer in length than â€Å"Our Kind of Love†, they both have the same point. One should take the time to examine both of these popular love poems/songs, because it is very interesting to see how big of an impact a difference in culture plays in World Literature. It is very amusing to see how a love poem written somewhere between 350 and 250 B. C. E. can relate so much to a contemporary country song.

The Realities and Challenges of Organizational Behavior free essay sample

A complete understanding of organizational behavior requires both an understanding of human behavior and an understanding of the organizational context within which human behavior is acted out. The fact that human beings make up a vital part of any organization is no secret. Indeed, organizational behavior provides a challenge. Much has been learned, and much more remains to be learned. The future portends even more change, even more challenges, even more complexity. Behavioral study provides performance feedback and insight into why employees behave a certain way and their informal social interactions. Organizations are open systems consisting of people, technology, structure, and purpose, which interact with elements in the organization’s environment. They face innumerable challenges on several fronts in their efforts to remain competitive. The correct application of organizational behavior, besides being interesting and practical, allows managers to identify workers who are extremely productive or especially unproductive and to comprehend why such differences exist and helps managers understand the complexity within organizations, identify problems, and determine the best way to correct them. We will write a custom essay sample on The Realities and Challenges of Organizational Behavior or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page For a company to be efficient, it needs to do more than just manage its assets and assign tasks to its personnel. Rather, it needs to adopt a holistic approach to organizational behavior which is humanistic. Organizational behavior has manifold implications for various managerial, organizational, and global challenges. It is the study of individual behavior and group dynamics in organizational settings which focuses on motivation, leadership, teamwork, and communication. Moreover, it also encompasses contemporary issues in organizations. Managers are concerned with the quantity and quality of the work their employees are performing. They must consider personal and environmental factors to understand fully how people behave in organizations and to help them grow to be all they can be. They should learn as much as possible about psychology in order to understand their employees. Four challenges for managers are the global environment, the workplace, ethical issues at work, and technological innovation. In addition, they must continually upgrade their knowledge about all aspects of their businesses, especially the human side of the organization. Reality reflects what is going on in all types of organizations public and private, large and small, product and service-oriented. It also reflects the themes of globalization, diversity, technology, and ethics. Challenges provide opportunities for us to grow and develop both as individuals and organizations. Challenge and opportunity are watchwords in organizations during these challenging times. Managers and employees alike are challenged to positively and optimistically meet change in how work gets done, change in psychological and legal interactions between individuals and organizations, change in personnel, and change in the basis for organization. As organizational behavior deals with understanding and managing people in the workplace, it is important to note that a successful organization makes use of the various kinds of expertise it possesses in order to enhance performance and pursues goals in a changing environment by adapting its behavior according to its knowledge about itself and the world it operates in. Moreover, it is skilled at creating, acquiring, organizing, and sharing knowledge, and at applying this knowledge to create its workplace culture. In general, most successful managers have a strong combination of technical, interpersonal, conceptual, and diagnostic skills. Managers of the future need to develop special skills to deal with the turbulence of change, and one of these important skills is the ability to promote creativity in organizations. The organization is successful to the extent that it mobilizes its resources effectively in the pursuit of organizational and human goals.
