Cloud Ingredients and Formation

Cloud Ingredients and Formation We all know what clouds are- visible collections of tiny water droplets (or ice crystals if its cold enough) that live high in the atmosphere above the Earths surface. But do you know how a cloud forms? In able for a cloud to form, several ingredients must be in place: watercooling air temperaturea surface to form on (nuclei) Once these ingredients are in place, they follow this process to form a cloud: Step 1: Change Water Vapor into Liquid Water Although we cant see it, the first ingredient water is always present in the atmosphere as  water vapor (a gas). But in order to grow a cloud, we need to get the water vapor from a gas to its liquid form. Clouds begin to form when a parcel of air rises from the surface up into the atmosphere. (Air does this in a number of ways, including being lifted up mountainsides, lifted up weather fronts, and being pushed together by converging air masses.) As the parcel ascends, it passes through lower and lower pressure levels (since pressure decreases with height). Recall that air tends to move from higher to lower pressure areas, so as the parcel travels into lower pressure areas, the air inside of it pushes outward, causing it to expand. It takes heat energy for this expansion to take place, and so the air parcel cools a bit. The further upward the air parcel travels, the more it cools. Cool air cant hold as much water vapor as warm air, so when its temperature cools down to the dew point temperature, the water vapor inside of the parcel becomes saturated (its relative humidity equals 100%) and ​condenses into droplets of liquid water. But by themselves, water molecules are too small to stick together and form cloud droplets. They need a larger, flatter surface on which they can collect. Step 2: Give Water Something to Sit on (Nuclei) In able for water droplets to form cloud droplets,  they must have something- some surface- to condense  on. Those somethings are tiny particles known as aerosols or  condensation nuclei. Just like the nucleus is the core or center of a cell in biology, cloud nuclei, are the centers of cloud droplets, and it is from this that they take their name. (Thats right, every cloud has a speck of dirt, dust, or salt at its center!) Cloud nuclei are solid particles like dust, pollen, dirt, smoke (from  forest fires, car exhaust, volcanoes, and coal-burning furnaces, etc.), and sea salt (from breaking ocean waves)  that are suspended in the air thanks to Mother Nature and us humans who put them there. Other particles in the atmosphere, including bacteria, can also play a role in serving as condensation nuclei. While we usually think of them as pollutants, they serve a key role in growing clouds because theyre hygroscopic- they attract water molecules. Step 3: A Cloud is Born! It is at this point- when water vapor condenses and settles onto condensation nuclei- that clouds form and become visible. (Thats right, every cloud has a speck of dirt, dust, or salt at its center!) Newly formed clouds will often have crisp, well-defined edges. The type of cloud and altitude (low, middle, or high) it forms at is determined by the level where an air parcel becomes saturated. This level changes based on things like temperature, dew point temperature, and how fast or slow the parcel cools with increasing elevation, known as lapse rate. What Makes Clouds Dissipate? If clouds form when water vapor cools and condenses, it only makes sense that they dissipate when the opposite happens- that is, when the air warms and evaporates. How does this happen? Because the atmosphere is always in motion, drier air follows behind the rising air so that both condensation and evaporation continually occur. When theres more evaporation taking place than condensation, the cloud will return once again become invisible moisture. Now that you know how clouds form in the atmosphere, learn to simulate cloud formation by making a cloud in a bottle. Edited by Tiffany Means

How Not to Be an Outcast in College

How Not to Be an Outcast in College Being an outcast, or socially inept in college is rather costly. It translates into a less productive and memorable college experience. Whatever, but if that’s something you would rather learn to avoid, then this article is for you. Though it’s a subjective topic, here’s a step by step breakdown of your typical anti-outcast college strategy. 1. Work on You First The only thing that separates you from anything, any goal or objective, is you. Within reason of course. But there are no real walls between you and a robust social life in college. The only thing in your way is your unique â€Å"narrative† that you define yourself with. Change that first. Work on you first. If your attitude is horrible, nothing else you do will help all that much anyway. 2. Read Some Dale Carnegie If you’re a college student today, chances are good ol’ Dale is a bit before your time. Whether you buy it as an eBook or paperback, read this: How to Win Friends and Influence People. If this were the only book you ever read for personal gain, it’s the perfect choice. Odds are just like the countless millions before you, you’ll not only read it again, but take notes and memorize his simple concepts as well. If readin Dale Carnegie is too much for you at the moment, at least read our article on how to deal with having no friends in college. 3. Be the Good Servant At all times be looking for ways to be of service to people without causing them to lose face in any way, or put yourself in a position where you end up getting taken advantage of. When you do get the chance to be of service, go above and beyond 100% of the time. Both Dale Carnegie and Napoleon Hill are big fans of the parable (New Testament). Seriously: If you develop this practice into a habit and stick to it, you will undoubtedly live a prosperous life and make many friends throughout your life. Though many people think that making friends after college is a struggle it is not really so. No matter what it is, go above and beyond without asking for extra pay or recognition. 4. Grow Up â€Å"Grow up† could mean all kinds of things. In this context, we’re referring to how you choose to project yourself to other people via your outward appearance. It doesn’t mean caving in completely, or totally selling out. It just means telling the world around you that you respect yourself. By all means sport some personality in your style, but make sure it’s clean. If you don’t take yourself seriously, hardly anyone else will. 5. Say These Two Things All the Time Let’s be clear, these are affirmations and there’s absolutely no question that they work miracles. Successful and worldly well-connected people use them every day of their lives. However, when you say these two things to yourself on a consistent basis (10 times a day in the beginning) embody them. Get into it! Make it real! Every day I meet the perfect people for me. No matter what I choose to do or say, the right people see and hear me. 6. Remember This Statement Check this out, and no, we haven’t the slightest clue who the quote originates from: â€Å"I am not what I think I am, and I am not what they think I am. I am what I think that they think I am.† Once the depth of that statement hits you and you really get it, you’ll never be the same. What you think people think about you (if they think about you at all) is almost complete rubbish. Yet, how much of what we say, do and think every day is influenced by this self-imposed illusion? Get it straight because this is reality: people really care about just one thing (themselves) no matter how you slice it. Regardless of how noble or righteous, at the end of the day all we really experience in this life is ourselves and no one else. 7. Play to Your Strengths In light of the last statement, you should obviously play to your own unique traits (strengths). You’re the only thing that sets you apart from everyone else, so express you and be unafraid. If it’s respect you want, this is the most direct route. When you play to your strengths and stand as yourself, unafraid before the insecure eyes of your peers, they will not only be drawn to you but regard you as a â€Å"really cool person† in that neutral sense that appeals to everyone. 8. Understand the 6 Human Needs The more you know about what every human being needs, the more equipped you are to use this knowledge to your benefit (and theirs). Comfort Uncertainty/Variety Love Growth Contribution Love/Connection As you can see, 99% of what it takes to avoid being an outcast in college is psychological in nature. And no, that doesn’t mean we think you should be a psych-major. What do you think, did we nail it? Tell us in the comments!

Critical analysis Journal opinion article - Essay Example The economies will be fully employed, allowing them to attain their potential in offering jobs and raise the income of their inhabitants. These will play a key role in helping generate high growth levels in cities, contributing to overall advancement of the entire economy (Sparshott). The latest outlooks evident in the case of American cities are optimistic, although some urban areas as well as their suburbs have populations representing about 86 percent of the regions’ population, while 88 percent are employed in nonfarm sectors. Even though more than half of the cities have attained record levels of employment, about one-third are anticipated to fail reaching this level when 2016 ends. Moreover, approximately 130 metropolitan areas are anticipated to penetrate the market in 2017, although they will be supporting few jobs unlike the case of the past decades. The areas that are recovering at the slowest rates are the older Midwestern regions, which were negatively influenced when the region lost a large number of jobs offered by the manufacturing sector. The deteriorating infrastructure and aging population will also play a role in preventing these areas from recovering, making them rank behind the top-advancing cities in the U.S. (Sparshott). In a different perspective, the boom witnessed in the oil sector, which played a key role in allowing certain cities in the U.S. boost their performance, is currently reversing progress. For instance, Midland, Texas portrayed fastest growth in 2014, but this is not the case presently. However, in 2015, the employment and economy of the metropolitan are anticipated to slow down and contract at the start of 2016. Overall, however, the cities in the U.S. are playing a key role in driving the growth of the economy, thus paving the way towards the recovery process. Moreover, even though some

Qustions - Essay Example The health system is a formal and orderly process made to function through the expertise and corresponding functions of health professionals involved in the care of patients. 3. HIV prevention mainly relates to health education. There is no other way to prevent HIV than by the education of the people about the disease, its causes, mode of transmission, and means of prevention. HIV prevention involves the active process of informing other people – children, adolescents, and adults – about the disease and how they can avoid getting it and how they can prevent its spread. This process can entail involving oneself in lectures in schools and health centers; making posters, pamphlets, and other educational materials on HIV and posting or making such materials available in schools, clinics, health centers, town halls, pharmacies, and other public institutions. 4. Informatics health is the process of digitizing the health system or process. It is about bringing health care services and the system online and accessible to the public. Informatics health is about using computers in data entry in hospitals and other health care institutions. It is about using such data to make a more dynamic and technologically updated process in health care delivery. My motivation in life and in enrolling in this course is my need to prove that learning can occur and can still happen at any age or stage of one’s life. I also want to learn more and to learn as much as I can about the practice and about the innovations available in the practice. Learning is a powerful motivator for me because it is a very engaging and invigorating process for me. I managed to attain a Bachelor Degree in Laboratory Medicine in the year 2005-2006 and I followed that with a year of internship in a hospital. Such internship enabled me to acquire practical experience. It taught me numerous skills – skills that I was not able to gain in my classes. In order to enhance my

The Most Disturbing Place I Have Ever Been to Essay Example for Free

The Most Disturbing Place I Have Ever Been to Essay Going to jail was no fun. It started off with a police officer placing me in handcuffs. The handcuffs were so tight that my hands went numb. Then I took a long ride in the back of a police car. I had to lean to the side so that I could ease the pressure of the handcuffs on my wrists. Next I arrived at the inmate-processing center. From the moment the door closed behind me, I was treated like inventory. I was photographed. I was fingerprinted. My money and car keys were taken. I was assigned a number so that I could be tracked and identified. I was placed in a cold cell made of concrete. I sat and waited for hours. I didn’t know what was going to happen next. I lost track of time because there were no clocks on the wall. I couldn’t tell if it was day or night. Jail is the most disturbing place I have ever been to. Then my name was called. An officer ordered me to line up against a wall along with eight other inmates. This became one of the worst times in my life. I was strip-searched. A group of officers ordered all inmates on the wall to get completely naked. One officer approached me and searched my clothes and shoes. Then he looked in my mouth and ears. He made me lift my private parts so that he could see down there. He ordered me to turn around and bend over. He took a quick look at my anal area. It seemed like minutes to me. I was totally embarrassed. Next I had to go through the rest of the inmate processing procedure. I was taken to a medical room to talk to a nurse and inform her of any problems I had. Then I was moved to a room where I could be classified according to my charge. Next I had to go to the shower room to clean up. I was only allowed a two minute shower. My clothes, including underwear, were taken. My underwear had color in them. I was not allowed to have colored underwear or colored socks. I was given a jail uniform that was too small. Then I was given one bologna and cheese sandwich. The guards didn’t care. Finally I was assigned to a permanent floor and tank. The tank held about twenty-five inmates. There was no privacy. It was overcrowded. Some inmates had to sleep on the floor, including me. There was one pay phone. Inmates argued over phone time. There were three toilets sitting out in the open. If I had to use the restroom, I had to use it in front of the other inmates. There was only one television. The guards controlled what I watched on television and when I watched it. I didnt get to make any decisions at all. Absolutely everything was decided for me. The guards told me when to get up, when to eat, when to exercise, when to shower, and when to sleep. I was in jail for three days. Jail is still the most disturbing place I have ever been to.

Descartes Vs. Pascal Essay -- essays research papers

Descartes vs. Pascal   Ã‚  Ã‚  Ã‚  Ã‚  For centuries, human beings have been debating over the validity of the use of reason. This is a very, very difficult subject to discuss, as one is forced to study something which is at that moment being used in their study. Two classic thinkers who contrasted on their view of reason were Descartes and Pascal. Though both saw reason as the primary source of knowledge, they disagreed over the competence of human reason. Descartes, the skeptic, said that we could use reason to find certain truth if we used it correctly, while Pascal said that we can't know certain truth, but reason is the best source of knowledge that we have. Descartes:   Ã‚  Ã‚  Ã‚  Ã‚  Reason is the tool by which we know everything that we know. But most people make the mistake of basing their reasoning on assumptions which are not known with 100% certainty. As I've said, â€Å"I am greatly astonished when I consider [the great feebleness of mind] and its proneness to fall [insensibly] into error† (K&B, p. 409). But it is possible to avoid falling into error if we use the valuable tool of reason correctly. In order to do this and find certainty, we must find something that we cannot doubt. This is impossible, as we can logically doubt anything. A certain truth must be something that is not logically possible to be false.   Ã‚  Ã‚  Ã‚  Ã‚  We must doubt, as that is the only way to find certain truth. It is the only way to wipe the slate clean of all of the uncertain assumptions which are believed and taught in the universities today. Just as mathematics will lead to uncertain assumptions if it is not built on certain truths, so will all use of reason lead to uncertain assumptions if it is not built on certain truths. There is a way to use doubt, though, to find certainty. If 100% certainty equals 0% doubt and we are certain that we can doubt everything, then we can use doubt as our certainty. We cannot doubt that we are doubting.   Ã‚  Ã‚  Ã‚  Ã‚  With our one certainty, we can now methodically use reason to find more certainties. For example, we can use the certainty â€Å"I am doubting† to find out that â€Å"I exist.† If I am doubting, than there must be an â€Å"I† who is doubting, which means that I must be. Like I've often said, â€Å"I think, therefore I am.† We can continue building on our certainties using rationa... ...e knowledge. Watson:   Ã‚  Ã‚  Ã‚  Ã‚  I agree with Pascal on his view of the capabilities of reason. We are feeble, misled creatures in the midst of a reality which we cannot know. Descartes was correct in his attempt to use mathematical logic to get rid of uncertain assumptions and find truth, but he needs to realize that most truth is beyond our reach. We, as thinking humans, do have the remarkable ability to study ourselves. Yet we have limitations in this study and cannot expect to be able to get a complete grasp of ourselves. Pascal was right on when he said that there are no complete skeptics. There are many things which we must accept, using reason, that we cannot prove with certainty.   Ã‚  Ã‚  Ã‚  Ã‚  I don't lean quite as far in Pascal's direction on his view of intuitionism. I believe that there is intuitive knowledge which we know with our heart. But this knowledge is only believed correctly when it is rationally processed. As with almost everything, we must find a balance between the use of reason and intuition. We err on the side of believing unreasonably if we use too much intuition, we become too skeptical if we ignore intuitive knowledge.

Descartes Meditation Essay

1. If Descartes’s aim is to find certainty, why does he proceed by doubting as many things as he can? He feels that as long as he goes on believing his old beliefs, laziness and habit will block him from receiving any truths. He feels that if he regards his beliefs in the same way as he does any falsehoods he can remain unbiased when judging information and only then will he receive real truths. 2. What reason does he give for doubting that the senses give knowledge? That a man asleep can have a realistic dream that he is having the same experiences as a man that’s awake. 3. What does the experience of â€Å"dreams† show us concerning the senses? He talks about how real dreams appear even though they are proven to be deceiving. And if one can be deceived in a dream by all of their senses can they not also be deceived in reality by some supernatural demon. He says hypothetically that God may not have created earth, shapes, etc. and everything that we sense could be a form of deception. 4. Why can he doubt even that 2=3 = 5. He talks about the fact that he sometimes doubt others who claim to have the most perfect knowledge. And if that can be the case for them can’t it also be possible for him to be wrong about â€Å"obvious† truths. Also, if one may feel that if God’s goodness would stop him from being deceived SOME of the time, wouldn’t it stop him from being deceived ALL of the time since he is clearly deceived some of the time. Basically he is acknowledging the fact that he could be wrong.
