Depression Is Not Only A State Of Feeling Sad - 1150 Words

Depression is not only a state of feeling sad, it is an illness that overpowers the ability to feel emotion, whether bad or good. Depression involves the mind, and it also involves the body and thoughts. This disorder can be passed down through genes or can be caused by a chemical imbalance in the brain. A biological cause of this disorder would be something such as enlarged adrenal glands. People who are depressed have a lower count of neurotransmitters involved with depression. An imbalance of hormones can also be connected to depression, therefore, when having too high of count of a hormone related to stress in particular (cortisol), depression may occur. Unfortunately, depression affects twenty percent of all Americans. Women are more likely to become depressed than men. Genes also have a lot to do with Depression. While studying twins, scientists have found that there is a powerful genetic influence in depression. Identical twins are three times more possible to have depression than fraternal twins raised in the same environment. In lecture we discussed that rates of MDD are two times greater in those with firs degree relatives. Symptoms caused by major depression can vary from person to person. Although depression may occur only one time during a person’s life, some people have multiple episodes of depression. During these episodes, symptoms occur most of the day, nearly every day for two weeks and may include: feeling sad and hopeless, and loss of interest, asShow MoreRelatedSadness857 Words   |  4 Pagesupset etc. Sadness is a state of mind that comes and goes as it pleases.

Seeing Through the Smog free essay sample

The first thing you notice is the smog. It drapes over the city in countless gray layers, extending from the sky to the ground. Then, just as your eyes begin to adjust, you’re hit by the smell. It’s that smell of factories and seaside pollution, of too many gas stations and too many cars. And, before you have time to think about what could possibly come next, you hear it. A constant stream of impatient honks and beeps mix with a poorly orchestrated ensemble of noises that charge at you from the televisions inside various surrounding apartments, as if maximum volume was the only option on the remote. And while trying to hear your own thoughts above all the madness, you will barely manage to step out of the way of the angry and unnecessarily rushed driver who just came very close to hitting you (as if pedestrians were outdated and people were born in cars), and you will probably wonder, â€Å"What IS this place?!† I’d like to welcome you to my heaven on eart h. We will write a custom essay sample on Seeing Through the Smog or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Before I moved to Greenwich in 2000, I lived in Beirut, Lebanon. I have gotten a pretty interesting range of reactions when I have told people that. In elementary and middle school, it was often met with an â€Å"Oh, in New Jersey!† or, from the few that knew it was a country, â€Å"Wait, so are you like, Muslim?† (Thankfully the reactions matured a bit more with high school and the war in ’06.) Initially though, it was frustrating coming from somewhere no one seemed to have heard anything about. Manaeesh (these thyme and sesame seed covered pizza-like things that deserve an essay of their own) were replaced with bagels, clusters of apartments turned into streets with actual houses (it took me several months to grasp the concept of basements), and the half hour of morning Arabic prayer led by Soeur Therese (one of the nuns at Jamhour) was cut down to a speedy, â€Å"I pledge allegiance†¦Ã¢â‚¬  Then came the war. The newspaper and TV flashed images of bom bs, destruction, and death. Phone calls from family in Beirut became more and more infrequent. Three years passed before I was able to go back again, and in those three years I did what so many do in the face of unwanted change: I shut my eyes and ignored it. The summer I finally went back was a slap to the face. When I returned, I expected nothing less than perfection. Instead, buildings I once played around had crumbled from explosions; the number of people, dirty and barefoot on the streets, had more than doubled, and my understanding of Arabic had vanished. Angry and confused, I kept asking myself where had my fairytale gone? My fifth day there, though, I had my big (excuse the cliche) epiphany. I had been waiting for my cousin outside of the nearby sandwich place, when a family pulled its car up next to me. The father rolled down the window and asked me in heavy Arabic, â€Å"Hello, could you tell me how many hours until this place closes?† It took me a few seconds, but I slowly answered, â€Å"In about four.† He thanked me and drove away. I stood there for a moment, trying to get a handle on what had just happened. Then I realized; I had understood. I had responded, in ARABIC! In what I think of as one of my happiest moments of clarity, I finally accepted that while so many things had changed, nothing was truly different. Buildings may have crumbled, but the country still stood strong. This provided me with a certain global awareness and cultural appreciation that I would not have had had it not been for the war. But these realizations extend further than just the boundaries of Lebanon. In August of 2009, I was part of a group of high school students from Trinity Church that traveled to the Dominican Republic. Our one-week trip was spent building a bakery and working with children in the village of Consuelo. While the manual labor was certainly rewarding, it was the people who left the greatest impression on me. There was the little boy, who so animatedly struggled to tell our group leader a story using the limited English he knew; Tete, one of the oldest women in the community, whose apparent love and devotion to her village and the people around her so strongly reminded me of my own family ties; the local translator, who, by joining us through language, nurtured a bond far beyond proverbial boundaries. It was with each of these people, with the village as a whole, that I felt a connection unlike any other. While many would feel uncomfortable with such an alien situation, an unknown language, an unknown culture, and an unknown place, Lebanon had fostered in me a s ense of adaptability and acceptance. In the people of Consuelo, I observed the same pride and cultural resilience that I feel for Beirut. Coming from a town like Greenwich makes it difficult for many to get past the cultural and language barriers presented by a new country. But in the same way that I remain hopeful and optimistic for Beirut, I remain open and faithful for Consuelo. Now, take a glimpse at the city again. The smog has cleared, and when you look through the buildings, standing tall and glorious despite their battle wounds, you can make out the people of Beirut. Masses of families and friends on the beach are oblivious to anything but the hummus in their stomachs and the warm waters of the Mediterranean on their toes; a man rides his bike down the sidewalk, toting a basket of fresh manaeesh just waiting to be eaten; a woman, in the midst of traffic, reaches out of her car window and gives a bottle of water to the frazzled boy wandering the streets. You step out of the way of the hurried driver, and he shouts a frantic apology out the window while throwing you a friendly wave. And now that you can finally hear your own thoughts, you will stop wondering and you will just know, â€Å"This place is perfection.†

Isotopes, sub-atomic particles and relative atomic mass free essay sample

Isotopes, sub-atomic particles and relative atomic mass Sub-atomic particles A subatomic particle Is a particle smaller than an atom: It may be elementary or composite. In 1905, Albert Einstein demonstrated the physical reality of the photons, hypothesized by Max Planck in 1900, in order to solve the problem of black body radiation In thermodynamics. In 1874, G. Johnstone Stoney postulated a rnlnlmum unit of electrical charge, for which he suggested the name electron in 1891. In 1897, J. J. Thomson confirmed Stoneys conjecture by discovering the first subatomic particle, the electron (now denoted e-). Subsequent speculation about the structure of atoms was severely constrained by Ernest Rutherfords 1907 gold foll experiment, showing that the atom is mainly empty space, with almost all its mass concentrated in a (relatively) tiny atomic nucleus. The development of the quantum theory led to the understanding of chemistry in terms of the arrangement of electrons in the mostly empty volume of atoms. We will write a custom essay sample on Isotopes, sub-atomic particles and relative atomic mass or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Particle physics and nuclear physics concern themselves with the study of these particles, their interactions, and matter made up of them which do not aggregate Into atoms. These particles include atomic constituents such s electrons, protons, and neutrons (protons and neutrons are actually composite particles, made up of quarks), as well as other particles such as photons and neutrinos which are produced copiously In the sun. However, most of the particles that have been discovered and studied are not encountered under normal earth conditions; they are produced in cosmic rays and during scattering processes in particle accelerators. Isotopes Isotopes are variants of a particular chemical element. While all isotopes of a given element share the same number of protons, each isotope differs from the others In its number of neutrons. Radioactive isotopes The existence of isotopes was first suggested in 1912 by the radiochemist Frederick Soddy, based on studies of radioactive decay chains which indicated about 40 1 OF3 ditterent species described as radioelements (i. e. radioactive elements) between uranium and lead, although the periodic table only allowed for 1 1 elements from uranium to lead. Several attempts to separate these new radioelements chemically had failed. For example, Soddy had shown in 1910 that mesothorium (later shown to be Ra-228), radium (Ra-226, the longest-lived isotope), and thorium X (Ra-224) are impossible to separate. Attempts to place the radioelements in the periodic table led Soddy and Kazimierz FaJans independently to propose their radioactive in 1913, to the effect that alpha decay produced an element two places to the left in the periodic table, while beta decay emission produced an element one place to the right. Soddy recognized that emission of an alpha particle followed by two beta particles led to the formation of an element chemically identical to the initial element but with a mass four units lighter and with different radioactive properties. Soddy proposed that several types of atoms (differing in radioactive properties) could occupy the ame place in the table. For example, the alpha-decay of uranium-235 forms thorium-231 , while the beta decay of actinium-230 forms thorium-230 The term isotope, Greek for at the same place, was suggested to Soddy by Margaret Todd, a Scottish physician and family friend, during a conversation in which he explained his ideas to her. In 1914 T. W. Richards found variations between the atomic weight of lead from different mineral sources, attributable to variations in isotopic composition due to different radioactive origins Stable isotopes The first evidence for isotopes of a stable (non-radioactive) element was found by J. J. Thomson in 1913 as part of his exploration into the composition of canal (positive ions). Thomson channelled streams of neon ions through a magnetic and an electric field and measured their deflection by placing a photographic plate in their path. Each stream created a glowing patch on the plate at the point it struck. Thomson observed two separate patches of light on the photographic plate (see image), which suggested two different parabolas of deflection. Thomson eventually concluded that some of the atoms in the neon gas were of higher mass than the rest. F. W. Aston subsequently discovered different stable isotopes for numerous elements sing a mass spectrograph. In 1919 Aston studied neon with sufficient resolution to show that the two isotopic masses are very close to the integers 20 and 22, and that neither is equal to the known molar mass (20. 2) of neon gas. This is an example of Astons whole number rule for isotopic masses, which states that large deviations of elemental molar masses from integers are primarily due to the fact that the element is a mixture of isotopes. Aston similarly showed that the molar mass of chlorine (35. 45) is a weighted average of the almost integral masses for the two isotopes Cl-35 and Cl-37. Relative atomic mass An atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of an atom of 12C The relative masses of atoms are measured using an instrument called a mass spectrometer, invented by the English physicist Francis William Aston (1877-1945) when ne was working in Cambridge wit J J. Thomson. It was in his use ot this instrument that the existence of isotopes of elements was discovered. Aston eventually discovered many of the naturally occurring isotopes of non-radioactive elements. He was awarded the Nobel Prize for Chemistry in 1922. Briefly, the mass pectrometer works by bombarding gaseous atoms with fast-moving electrons which knock out an electron from the atom. The cations formed are brought down on to a detector in turn according to their mass. The instrument provides a measure of the relative mass (compared to 12C) and the relative number of each isotope. The diagrams below represent the mass spectrum of naturally occurring chlorine. The above right spectrum has been represented so that the most abundant isotope has a relative abundance of 100%, with the other mass peaks scaled in relation to this. The relative atomic mass of chlorine is now calculated as shown below:
