Samual Hahnemann essays

Samual Hahnemann essays Once upon a time, in a land far far away, a legacy was born. The greatest genius in medical history - Samuel Christian Hahnemann. The year was 1755, April 11. In a little village known as Meissen, which is located in Saxony, Germany. Born to poor folk of the time, his father was employed as a porcelain painter. His mother, like other women of the time, was a housewife, looking after her husband, Sam and his other siblings. Sam was a clever young man, who must have showed his intelligence from a very young age. He was often shut into a room by his father to ponder tricky questions. The substance of his fathers advice to him during his growing up years was prove all things, hold fast to what is good, dare to be wise (and be good to your mum!!!). This ultimately cultivated original thinking in young Sam. Due to his familys situation, money was scarce in Sams younger years, which unfortunately led to him being frequently taken out of school. Thankfully for his thirst for knowledge, he began paying for his own schooling by the age of 12. He did this by tutoring his fellow students in not only Latin but Greek as well. This led to him being admitted to the Princes School in St Afra, Meissen in 1770, free of charge on the premise of him being such a brilliant student. He left 5 years later, after presenting a report titled The wonderful construction of the human hand. This was just the beginning, the beginning of a remarkable prominent place in the history of medicine. In the spring of 1775, he began to do formal studies of medicine. Supporting himself through tutoring once again, then progressing into translating books on medicine, botany and chemistry. Its a wonder he ever found time to scratch himself. Then again because of his brilliance, he found himself attending lectures for free. Sam was 29, when he finally received his degree in medicine. ...

Gun control Essay Example | Topics and Well Written Essays - 1000 words

Gun control - Essay Example It is easy to deem this as a trigger happy syndrome but the fact remains to be very volatile and fearful. The statistics that have been formulated in regard to continuations of violence and the sources of the violent behavior have become staggering. In November 1998 a Japanese student new in California was shot dead when he tried to find a specific address from a middle aged resident at the middle of the night due to miscommunication and language problem. (King, 317) Such examples are abundant and this is the reason it is necessary to look into the matter of gun control policy. Furthermore, experts amidst researchers and policymakers should managed considerable thought toward understanding how short and long term influences of abuse, including drugs, alcohol, and other substance abuse along with mental health stress. The understanding of immediate affects abuse would have, how it relates to voluntary behaviors. The main objective of the research would to develop a form of argumentative system that would be instrumental in helping out the policymakers and enable them to lead a normal logical conclusion on the subject of gun control policy and life within the main stream of the society. (Lamb, 37) 2. 2. For this purpose it is needed to formulate a policy or practice that would enable the government to determine a policy to put restriction on the guns. It s important to include population from different walks of life and interview them for their views on the subject opposing the policy unrestricted access to firearms. The formulation of this research would be based on the surveys taken on the various government officials, general population and adolescents whereby it would be ascertained about the amount of agreement on the topic of gun control in the United States. Alongside a large amount of data would be collected to determine the detrimental affects of free ownership of guns in the mass population without government restrictions. This would also be accompanied by data regarding firearms related crimes in the United States and United Kingdoms. United Kingdoms would be taken into consideration to evaluate the effects of government regulation of firearms and the firearms rela ted crime rates of the two nations would be compared. A memorandum prepared in this process would be a vital part of the proposal to eradicate the policy unrestricted access to firearms.It is believed that the adolescents suffering from victimization goes through a huge psychological defoliation therefore it is important to address this case and the ultimate affect when some of them get free access to firearms. The government officials would be taken into consideration, specifically security and law enforcement officials, because these are the section that could convey the actual result of free access to firearms. Lastly, the general population would be considered because they are the main sufferers and it is important to incorporate their individual and social views. The main memorandum backed by the amount of research would certainly prove to be helpful while influencing the policymakers of the US authority. It is obvious that the policy of presenting well researched memorandum is viable to expose risk of unrestricted acce

Primary Source Analysis Essay Example | Topics and Well Written Essays - 1250 words

Primary Source Analysis - Essay Example It is further claimed that their pride and the number is responsible for their party disputes. These conflicts, however, were beneficial because they led to the introduction of schools and formation of laws. That is actually why Bridge Town, the Capital of Barbados, became a Seminary of Jews. This essay seeks to analyze Document 1 Chapter 6, showing how the Jews historical injustices have affected they way they are treated by other communities many years after. The petitioners presented their plea to the Majesty, claiming that their misfortunes and collapse of trade in the island should be addressed, though their argument seems farfetched; it is hard to believe that all their trouble is caused by the Jews. Although the Jews have a long history including the common Oath taken on the five books of Moses, there seems to be injustices resulting from this history especially when their traditional Oaths are used in courts as evidence. In other words, the Oaths that were taken in those days are long gone and should not be considered in courts. Essentially, it is foolhardy to factor in the history of Jews when deciding their cases in courts. In conclusion, some of the issues raised by the petitioners, especially incriminating the Jews based on their history have some basis and should be addressed.1 Account of the Destruction of the Speightstown Synagogue in Barbados, 1739 This letter was written by Barbadian planters to the Governor Burnet on August 1, 1793. The letter is a funny recount of a hideous man by the name of Burnet, who claimed to be the son of the late Governor Burnet. This part analyzes Document 2, showing how the Jews are treated with contempt because of their unbecoming behavior. This man complained of head ache when he was attending a young Jews wedding. Thereafter, Lopus welcomed him in his house for first aid, an offer he accepted. However, Lopus turned up with his men and manhandled him and charged him with robbery. This incident puzzled the so calle d Burnet so much. The situation worsened when a mob from Speightstown turned up against him in an uproar, suing and forcing him to pay several counts of damages. Consequently, the Leeward people were extremely pissed off that they decided to drive the Jews out of the town and destroyed their Synagogue. In a rejoinder, the Jews congregated at the Bridgetowm and resolved to use their wealth to protect their men in the Island. It seems true that the young man, who was punished, was an imposter. However, the magnitude of this punishment revealed some deep-rooted rivalry between the resident of this Island and the Jews. There seems to be an entrenched hatred for the Jews, which originated from historical injustices, which allowed them to accumulate a lot of wealth. The mob took advantage of this incident to vent their anger against the Jews. In an attempt to resolve the matter, the court decided to swear the Jews by their long Oath. However, I find this swearing unfounded and unnecessary because it may not force the Jews to reveal the wrong that they have committed. The swearing has the words ‘I swear to speak the whole truth’ is meaningless as the Jews will not be cowed down by these words. If they have resolved to fight for their justice, they will still ignore those swearing and hence; they will not reveal any information that will make them lose in the case.2 III. The â€Å"Confession Made by Cyrus†

Work-Life Balance Research Paper Example | Topics and Well Written Essays - 1250 words

Work-Life Balance - Research Paper Example Given the fact that we live in a world today that has fierce competitiveness as one of its main features, there remains no ambiguity in the ultimate work responsibilities one is rendered to fulfill along with fulfilling the family demands. Maintaining work-life balance is an issue which is hotly debated since the level of competitiveness has spiraled up with a blinding speed and many strategies have been presented by expert sociologists over the past many years for educating the novice people as to how they can stop all kinds of new and tiring problems from cropping up nearly everyday. Work and family relationships are more than often found at odds and highly conflicting which is why the reason I have chosen sharing the horrendous pressures I face everyday, personal sacrifices I make everyday to fulfill my family requirements, and the steps I take to frantically try to maintain a decent balance between my work and family. Considering the phenomenally engaging studies I have to contin ue in an order to establish a successful professional career, meeting up with the expectations of my wife and son presents a challenge fraught with difficulties and sacrifices. Struggling with competing family demands, especially when one has to spend countless hours in studying intricate subjects, raises a phenomenally tedious and grueling life situation which I have tried to picture in this paper. I happen to live in Canada with my wife and son and while I am doing my diploma from The Northern Alberta Institute of Technology (NAIT), my wife studies at University of Alberta. This is understandable that things take on a real different turn when not one but both partners have their own issues to deal with in life and not one of them has full time to spare for home and children. While both me and my wife are struggling really hard to complete our studies so that a better life standard could be established, I do not feel compelled to lie about the harsh realities of life and how many c ritically important things related to family are left at stake as hard battle for a secure future continues with seemingly no end to it. The battle for securing the basic necessities of life in Canada where earning significantly commendable feats at workplace is not an easy job is not fought by me alone, but my wife also has to deal with an extremely hectic study module due to which both of us are left with quite little time that we can share with each other and with our son. Had it been a situation where I already would have been working as a successful employee in some notable firm and earning respectable amount of money, I could have induced my wife to give up her busy schedule and devote her time to our son so that the incidence of gruel problems and fear of a broken family could be propelled down. But, considering the reality that not one of us are at the current time even at the beginning stage of our professional careers since we are in the process of making our way to that b eginning that grows over time to encompass a professional achievement, the looming prospect of a broken family seems quite hard to evade at times. This is also because of the factor that I find myriad examples of broken families around me nearly every single day of my life and the reason which lays the foundation for such tragic breakups could be more than often narrowed down to unavailability of time which happens to be a killing poison for even the type of couples who share phenomenal understanding. Considering my situation, I cannot rate my work and family according to the level of importance I allot each, rather both work and family are central to my life and finding a reasonable balance between the two is an issue I have gone through over and over again in my

What Is The Main Purpose Of A Satellite Media Essay

What Is The Main Purpose Of A Satellite Media Essay A satellite is basically any object that revolves around a planet in a circular or elliptical path. The moon is Earths original, natural satellite, and there are many manmade (artificial) satellites, usually closer to Earth. The path a satellite follows is an orbit. In the orbit, the farthest point from Earth is the apogee, and the nearest point is the perigee. Artificial satellites generally are not mass-produced. Most satellites are custom built to perform their intended functions. Exceptions include the GPS satellites (with over 20 copies in orbit) and the Iridium satellites (with over 60 copies in orbit). Approximately 23,000 items of space junk objects large enough to track with radar that were inadvertently placed in orbit or have outlived their usefulness are floating above Earth. The actual number varies depending on which agency is counting. Payloads that go into the wrong orbit, satellites with run-down batteries and leftover rocket boosters all contribute to the count. This online catalog of satellites has almost 26,000 entries! Although anything that is in orbit around Earth is technically a satellite, the term satellite is typically used to describe a useful object placed in orbit purposely to perform some specific mission or task. In other words, satellite also refers to an artificial satellite also which is a man-made object that orbits the Earth or another body. Scientists may also use the term to refer to natural satellite. Natural Satellite Moon, the common noun, is used to mean any natural satellite. There are at least 140 moons within the solar system and in fact many others orbiting the planets of other stars. There is a standard model of moon formation from the same collapsing region of protoplanetary disk. This give rise to primary. There are also exceptions or variations in this regard. Several moons are thought to be captured asteroids; others may be fragments of larger moons collapsed by impacts, a portion of the planet itself blasted into orbit by a large impact. As most moons are known only through a few observations via investigations or telescopes, most theories about their origins are still uncertain. Artificial Satellites An artificial satellite is a manufactured object that continuously orbits Earth or some other body in space. Most artificial satellites orbit Earth. People use them to study the universe, help forecast the weather, transfer telephone calls over the oceans, assist in the navigation of ships and aircraft, monitor crops and other resources, and support military activities. Artificial satellites also have orbited the moon, the sun, asteroids, and the planets Venus, Mars, and Jupiter. Such satellites mainly gather information about the bodies they orbit. Piloted spacecraft in orbit, such as space capsules, space shuttle orbiters, and space stations, are also considered artificial satellites. So, too, are orbiting pieces of space junk, such as burned-out rocket boosters and empty fuel tanks that have not fallen to Earth. Artificial satellites differ from natural satellites, natural objects that orbit a planet. Earths moon is a natural satellite. The Soviet Union launched the first artificial satellite, Sputnik 1, in 1957. Since then, the United States and about 40 other countries have developed, launched, and operated satellites. Today, about 3,000 useful satellites and 6,000 pieces of space junk are orbiting Earth. Satellite orbits Satellite orbits have a variety of shapes. Some are circular, while others are highly elliptical (egg-shaped). Orbits also vary in altitude. Some circular orbits, for example, are just above the atmosphere at an altitude of about 155 miles (250 kilometers), while others are more than 20,000 miles (32,200 kilometers) above Earth. The greater the altitude, the longer the orbital period the time it takes a satellite to complete one orbit. A satellite remains in orbit because of a balance between the satellites velocity (speed at which it would travel in a straight line) and the gravitational force between the satellite and Earth. Were it not for the pull of gravity, a satellites velocity would send it flying away from Earth in a straight line. But were it not for velocity, gravity would pull a satellite back to Earth. To help understand the balance between gravity and velocity, consider what happens when a small weight is attached to a string and swung in a circle. If the string were to break, the weight would fly off in a straight line. However, the string acts like gravity, keeping the weight in its orbit. The weight and string can also show the relationship between a satellites altitude and its orbital period. A long string is like a high altitude. The weight takes a relatively long time to complete one circle. A short string is like a low altitude. The weight has a relatively short orbital period. Many types of orbits exist, but most artificial satellites orbiting Earth travel in one of four types: (1) high altitude, geosynchronous; (2) medium altitude, (3) sun-synchronous, polar; and (4) low altitude. Most orbits of these four types are circular. A high altitude, geosynchronous orbit lies above the equator at an altitude of about 22,300 miles (35,900 kilometers). A satellite in this orbit travels around Earths axis in exactly the same time, and in the same direction, as Earth rotates about its axis. Thus, as seen from Earth, the satellite always appears at the same place in the sky overhead. To boost a satellite into this orbit requires a large, powerful launch vehicle. A medium altitude orbit has an altitude of about 12,400 miles (20,000 kilometers) and an orbital period of 12 hours. The orbit is outside Earths atmosphere and is thus very stable. Radio signals sent from a satellite at medium altitude can be received over a large area of Earths surface. The stability and wide coverage of the orbit make it ideal for navigation satellites. A sun-synchronous, polar orbit has a fairly low altitude and passes almost directly over the North and South poles. A slow drift of the orbits position is coordinated with Earths movement around the sun in such a way that the satellite always crosses the equator at the same local time on Earth. Because the satellite flies over all latitudes, its instruments can gather information on almost the entire surface of Earth. One example of this type of orbit is that of the TERRA Earth Observing Systems NOAA-H satellite. This satellite studies how natural cycles and human activities affect Earths climate. The altitude of its orbit is 438 miles (705 kilometers), and the orbital period is 99 minutes. When the satellite crosses the equator, the local time is always either 10:30 a.m. or 10:30 p.m. A low altitude orbit is just above Earths atmosphere, where there is almost no air to cause drag on the spacecraft and reduce its speed. Less energy is required to launch a satellite into this type of orbit than into any other orbit. Satellites that point toward deep space and provide scientific information generally operate in this type of orbit. The Hubble Space Telescope, for example, operates at an altitude of about 380 miles (610 kilometers), with an orbital period of 97 minutes. Types of artificial satellites Artificial satellites are classified according to their mission. There are six main types of artificial satellites: (1) scientific research, (2) weather, (3) communications, (4) navigation, (5) Earth observing, and (6) military. Scientific research satellites gather data for scientific analysis. These satellites are usually designed to perform one of three kinds of missions. (1) Some gather information about the composition and effects of the space near Earth. They may be placed in any of various orbits, depending on the type of measurements they are to make. (2) Other satellites record changes in Earth and its atmosphere. Many of them travel in sun-synchronous, polar orbits. (3) Still others observe planets, stars, and other distant objects. Most of these satellites operate in low altitude orbits. Scientific research satellites also orbit other planets, the moon, and the sun. Weather Satellites Weather satellites help scientists study weather patterns and forecast the weather. Weather satellites observe the atmospheric conditions over large areas. Some weather satellites travel in a sun-synchronous, polar orbit, from which they make close, detailed observations of weather over the entire Earth. Their instruments measure cloud cover, temperature, air pressure, precipitation, and the chemical composition of the atmosphere. Because these satellites always observe Earth at the same local time of day, scientists can easily compare weather data collected under constant sunlight conditions. The network of weather satellites in these orbits also functions as a search and rescue system. They are equipped to detect distress signals from all commercial, and many private, planes and ships. Other weather satellites are placed in high altitude, geosynchronous orbits. From these orbits, they can always observe weather activity over nearly half the surface of Earth at the same time. These satellites photograph changing cloud formations. They also produce infrared images, which show the amount of heat coming from Earth and the clouds. Communication Satellites Communications satellites serve as relay stations, receiving radio signals from one location and transmitting them to another. A communications satellite can relay several television programs or many thousands of telephone calls at once. Communications satellites are usually put in a high altitude, geosynchronous orbit over a ground station. A ground station has a large dish antenna for transmitting and receiving radio signals. Sometimes, a group of low orbit communications satellites arranged in a network, called a constellation, work together by relaying information to each other and to users on the ground. Countries and commercial organizations, such as television broadcasters and telephone companies, use these satellites continuously. Navigation Satellites Navigation satellites enable operators of aircraft, ships, and land vehicles anywhere on Earth to determine their locations with great accuracy. Hikers and other people on foot can also use the satellites for this purpose. The satellites send out radio signals that are picked up by a computerized receiver carried on a vehicle or held in the hand. Navigation satellites operate in networks, and signals from a network can reach receivers anywhere on Earth. The receiver calculates its distance from at least three satellites whose signals it has received. It uses this information to determine its location. Earth Observing Satellites Earth observing satellites are used to map and monitor our planets resources and ever-changing chemical life cycles. They follow sun-synchronous, polar orbits. Under constant, consistent illumination from the sun, they take pictures in different colors of visible light and non-visible radiation. Computers on Earth combine and analyze the pictures. Scientists use Earth observing satellites to locate mineral deposits, to determine the location and size of freshwater supplies, to identify sources of pollution and study its effects, and to detect the spread of disease in crops and forests. Military Satellites Military satellites include weather, communications, navigation, and Earth observing satellites used for military purposes. Some military satellites often called spy satellites can detect the launch of missiles, the course of ships at sea, and the movement of military equipment on the ground. The life and death of a satellite Building a satellite Every satellite carries special instruments that enable it to perform its mission. For example, a satellite that studies the universe has a telescope. A satellite that helps forecast the weather carries cameras to track the movement of clouds. In addition to such mission-specific instruments, all satellites have basic subsystems; groups of devices that help the instruments work together and keep the satellite operating. For example, a power subsystem generates, stores, and distributes a satellites electric power. This subsystem may include panels of solar cells that gather energy from the sun. Command and data handling subsystems consist of computers that gather and process data from the instruments and execute commands from Earth. A satellites instruments and subsystems are designed, built, and tested individually. Workers install them on the satellite one at a time until the satellite is complete. Then the satellite is tested under conditions like those that the satellite will encounter during launch and while in space. If the satellite passes all tests, it is ready to be launched. Launching the satellite Space shuttles carry some satellites into space, but most satellites are launched by rockets that fall into the ocean after their fuel is spent. Many satellites require minor adjustments of their orbit before they begin to perform their function. Built-in rockets called thrusters make these adjustments. Once a satellite is placed into a stable orbit, it can remain there for a long time without further adjustment. Performing the mission Most satellites operate are directed from a control center on Earth. Computers and human operators at the control center monitor the satellites position, send instructions to its computers, and retrieve information that the satellite has gathered. The control center communicates with the satellite by radio. Ground stations within the satellites range send and receive the radio signals. A satellite does not usually receive constant direction from its control center. It is like an orbiting robot. It controls its solar panels to keep them pointed toward the sun and keeps its antennas ready to receive commands. Its instruments automatically collect information. Satellites in a high altitude, geosynchronous orbit are always in contact with Earth. Ground stations can contact satellites in low orbits as often as 12 times a day. During each contact, the satellite transmits information and receives instructions. Each contact must be completed during the time the satellite passes overhead about 10 minutes. If some part of a satellite breaks down, but the satellite remains capable of doing useful work, the satellite owner usually will continue to operate it. In some cases, ground controllers can repair or reprogram the satellite. In rare instances, space shuttle crews have retrieved and repaired satellites in space. If the satellite can no longer perform usefully and cannot be repaired or reprogrammed, operators from the control center will send a signal to shut it off. Falling from orbit A satellite remains in orbit until its velocity decreases and gravitational force pulls it down into a relatively dense part of the atmosphere. A satellite slows down due to occasional impact with air molecules in the upper atmosphere and the gentle pressure of the suns energy. When the gravitational force pulls the satellite down far enough into the atmosphere, the satellite rapidly compresses the air in front of it. This air becomes so hot that most or all of the satellite burns up. Importance of Satellite Satellites were exotic, top-secret devices. They were used primarily in a military capacity, for activities such as navigation and espionage. Now they are an essential part of our daily lives. We see and recognize their use in weather reports, television transmission by DIRECTV and the DISH Network, and everyday telephone calls. In many other instances, satellites play a background role that escapes our notice: Some newspapers and magazines are more timely because they transmit their text and images to multiple printing sites via satellite to speed local distribution. Before sending signals down the wire into our houses, cable television depends on satellites to distribute its transmissions. The most reliable taxi and limousine drivers are sometimes using the satellite-based Global Positioning System (GPS) to take us to the proper destination. The goods we buy often reach distributors and retailers more efficiently and safely because trucking firms track the progress of their vehicles with the same GPS. Sometimes firms will even tell their drivers that they are driving too fast. Emergency radio beacons from downed aircraft and distressed ships may reach search-and-rescue teams when satellites relay the signal. Miniaturized satellite Classification: Minisatellite Microsatellite Nanosatellite Picosatellite Miniaturized satellites are artificial satellites of ordinarily low weights and small sizes, usually under 500Â  kg (1,100 lb.). While all such satellites can be referred to as small satellites, different classifications are used to categorize them based on mass as given below. One reason for miniaturizing satellites is to reduce the cost: heavier satellites require larger rockets of greater cost to finance; smaller and lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in multiples. They can also be launched piggyback, using excess capacity on larger launch vehicles. Miniaturized satellites allow for cheaper designs as well as ease of mass production, although few satellites of any size other than communications constellations where dozens of satellites are used to cover the globe have been mass produced in practice. Besides the cost issue, the main motivation for the use of miniaturized satellites is the opportunity to enable missions that a larger satellite could not accomplish, such as: Constellations for low data rate communications. Using formations to gather data from multiple points. In-orbit inspection of larger satellites. Minisatellite The term minisatellite usually refers to an artificial satellite with a wet mass (including fuel) between 100 and 500 kg (220 and 1,100 lb.), though these are usually simply called small satellites. Minisatellites are usually simpler but use the same technologies as larger satellites. Microsatellite Microsatellite or microsat is usually applied to the name of an artificial satellite with a wet mass between 10 and 100 kg (22 and 220 lb.). However, this is not an official convention and sometimes microsat can refer to satellites larger than that. Sometimes designs or proposed designs of these types have microsatellites working together or in a formation. The generic term small satellite is also sometimes used. Nanosatellite The term nanosatellite or nanosat is usually applied to the name of an artificial satellite with a wet mass between 1 and 10 kg (2.2 and 22 lb.). Again designs and proposed designs of these types usually have multiple nanosatellites working together or in formation (sometimes the term swarm is applied). Some designs require a larger mother satellite for communication with ground controllers or for launching and docking with nanosatellites. Picosatellite Picosatellite or picosat (not to be confused with the PICOSat series of microsatellites) is usually applied to the name of an artificial satellite with a wet mass between .1 and 1 kg (0.22 and 2.2 lb.). Again designs and proposed designs of these types usually have multiple Picosatellites working together or in formation (sometimes the term swarm is applied). Some designs require a larger mother satellite for communication with ground controllers or for launching and docking with Picosatellite. The CubeSat design, with 1 kg maximum mass, is an example of a large Picosatellite . Cube Sat A CubeSat is a type of miniaturized satellite for space research that usually has a volume of exactly one liter (10Â  cm cube), weighs no more than 1.33 kilogram, and typically uses commercial off-the-shelf electronics components. CubeSat isometric drawing Since CubeSats are all 1010 cm (regardless of length) they can all be launched and deployed using a common deployment system. CubeSats are typically launched and deployed from a mechanism called a Poly-Picosatellite Orbital Deployer (P-POD), also developed and built by Cal Poly. The P-POD is a rectangular box with a door and a spring mechanism. It is made up of anodized aluminum. They are mounted to a launch vehicle and carry CubeSats into orbit and deploy them once the proper signal is received from the launch vehicle. The P-POD Mk III has capacity for three 1U CubeSats however, since three 1U CubeSats are exactly the same size as one 3U CubeSat, and two 1U CubeSats are the same size as one 2U CubeSat, the P-POD can deploy 1U, 2U, or 3U CubeSats in any combination up to a maximum volume of 3U. CubeSats are being used for everything from environmental sensing and fundamental biology research to testing new space flight systems. Poly Picosatellite Orbital Deployer (P-POD) and cross section CubeSat forms a cost-effective independent means of getting a payload into orbit. Most CubeSats carry one or two scientific instruments as their primary mission payload. Several companies and research institutes offer regular launch opportunities in clusters of several cubes. ISC Kosmotras and Eurokot are two companies that offer such services. The biggest advantage of Nano- and Pico-satellites is that they are a bargain. Most of the cost saving comes at the launch stage. Unlike conventional satellites, they dont need a dedicated launch vehicle where they are the primary payload. Their affordability also comes from being built with off-the-shelf electronic circuit chips such as microprocessors and radio frequency transmitters and receivers. These are the same components that are inside smart phones, hand-held Global Positioning system units, and digital cameras.

Fire And Ice - Compared To 4 Other Poems Essay -- essays research pape

Five Great Pieces of Thought I think Robert Frost is a understandable, but yet an unconventional poet. Frost wrote in his own style, and as a result, he took quite a bit of heat from the critics of his period. Frost has an elegant style of writing descriptive and understandable poems. I am going to tell you about the five best pieces he has ever written. First off, "A Considerable Speck" is a unusual poem about Frost noticing a tiny speck on his paper. Upon further observation, Frost notices that the speck is actually a extremely tiny mite, struggling to avoid being crushed by Frost’s pen. Frost appreciates the insect’s battle to stay alive and leaves it on his paper. Frost allows the mite to sleep on his paper because he values any intelligence, even one that is small as a bug’s. This poem is told directly from Robert Frost’s mouth. It shows how much the poet appreciates the little things in life. Regardless of size Frost understands that a life is a life, and all lives are important. The imagery in this poem is very clear to me. I can picture an old man trying to blow a piece of dirt off the paper. Then the piece of dirt starts moving, as he sees what he believes to be a dot on the paper but really to be a mite. The old man then starts to think about the value of life. The theme of the poem is that there is no such thing as an insignificant speck. Everything and everyone has a purpose for being here. This poem is filled with alliteration. Some examples I found are: cunning crept, tenderer-than-thou, and breathing blown (Silberner 98). Mind is repeated three times in the final stanza. Also there were two instances in which Frost used assonance room for and living mite. The rhyme scheme of the first stanza of "A Considerable Speck" is AABBCCDADEEFGFGHH, but there is no pattern throughout the poem (Silberner 99). Next I would like to tell you about is "Ghost House". It is an remarkably descriptive poem illustrating an aged, haunted house. The imagery in this poem is marvelous. This poem allows the reader to see the house as if he were standing on the front porch. You can picture an old decrepit house, covered with vines and wild raspberries. There is a dying tree in the front yard, with only one vital branch on it. Beneath the tree there are two gravestones so covered in moss that the names cannot be... ...uching poem to me because I was always taught to be my own person and I thank my parents for that. Robert Frost’s life started out quite different than most people. He never had any formal schooling until he was the age of twelve years old. This wasn’t the way you would think a famous writer would start off his life. The even awkward part of this story is that he graduated Lawrence High School as co-valedictorian of his graduating class. When I saw that I was very struck. I realized that changing is all up to one person and that one person is you. Robert Frost’s life took drastic changes and as a result of this his poetry varies quite a bit (Silberner 192). At the time he was writing his more depressing poems, he was having trouble getting his poems published, and he was doing oddball jobs to make ends meet (Gioia and Kennedy 522). His more upbeat poems were not created until after magazines began printing his work. Robert Frost is a simple, yet powerful poet. He uses small, understandable words, which show very powerful meanings. The main reason why I appreci ate Frost’s work is because I can understand it, which is more than I can say for the majority of poetry that I have read.

Organizational Behavior-Communication Essay

1. Present which channels of communications should be emphasized and how these channels will be used to ensure that the traditional departments (e.g., IT, human resources, customer service, and sales) at SWC headquarters have necessary accurate and timely information. Communication in an organization or company is very important in achieving goals and objectives. It is oftentimes used in relaying information, messages and issues that concern the success of a company or organization. It is the medium used by most of the high ranking officials and members to have an organized and timely delivery of information in every office or department for instance. Various types of communication or channels had been used. These communication channels are used by the companies to convey and interact well with the employees in order to improve and attain growth of the organization. There are two types of channels—indirect and direct communication. Indirect communication is used when the interaction is not face-to-face. It uses medium such as different types of technologies like computers, monitors and among others. The most common type of indirect communication is the teleconferencing.   On the other hand, direct communication is a face-to-face type of communication. This is common when all of the members of the team are present in just one area. 2. Which channels will be key to those work teams with all members located within headquarters? In the case of SWC, all of the members of the team are within the headquarters, it is best to use direct communication. In relaying this message , a memo can be sent to the members of the team to inform them of the activity that will be done within the headquarters. It is a common knowledge that doing a meeting or gathering within a certain place when all of the people are present, it is best to employ the direct communication. If the head of the department do not have the time to write a memo the most common thing done is to send an email to the members stating the information and issues that should be discussed and later on meet face-to-face with the members. It is not advisable that the leader will just send an email to all the members even if all are present within one area. On the other hand, an email might be good to relay the information fast and easy but still it connotes something to the members. The members might think that the leader of the team is not interested in talking with them. So, there are also strengths and weaknesses of these channels. But in this case, a good leader nurtures a relationship with the members through constant socialization, constant talking with them and assuring that the company is still wants them and will be like a friend that whenever the company decides to change leadership and people the members will be the first to know. It is showing of sincerity with the members of the team. In a study done by the Harvard business school, they projected what a good manager is. They found out that the effective manager spends more than 80 percent of their time in interacting with their personnel and staff. Furthermore, their study said that interaction and conversations within the working area is important in leading a company or organization. It is human capital and social capital that is working in order to achieve and create what the company wants such as increasing productivity while enhancing innovation. In another research done by Ron Burt from the University of Chicago, a leading researcher on the social capital of managers has found, through numerous studies, that certain patterns of connections that individuals build with others brings them higher pay, earlier promotions, greater influence, better ideas and overall greater career success. Burt believes that good social capital provides a much higher return on investment in human capital – the two work toge ther. (Krebs, 2005) In another research done at the Norwegian school of economics, a manager or team leader with a better social networking were more productive since they are sincere with their work, they can easily coordinate with the members without hesitation and coordinate tasks in order to finish a certain project and accomplish the goals and objectives of the project (Krebs, 2005). 3. We may have virtual self-managed teams with members located in different parts of the world. The members have yet to meet each other. These teams are each focusing on designing and delivering specific products to certain customers by designated dates. On the other hand, while face-to-face interaction is important in achieving productivity the introduction of various technologies cannot be ignored. Some of the teams of SWC are located in various areas where there is difficulty of meeting face-to-face. In this kind of interaction, teleconferencing has been used by many organizations and companies in order to hold a meeting or to discuss an issue that concerns the company. Also, one of the successful interactions is through networking. This technology helps individuals communicate with each other even if it is across the world. It is a laborious and costly though but once it is set up many of the staff outside the headquarters will benefit from it. From this networking there will be better information flow and exchange of communication among the team members(Lussier, 2005) If SWC were to consider the virtual self-managed teams, below are some key areas that would be evaluated. A virtual self-managed team has been around the globe today. It is used by the outsourcing companies such as call centers, medical transcriptionist, and even tutorials online. Through the introduction of the technology people have embraced this and been nurturing and disseminating it to the others. But before going into a deeper context of the virtual self-managed team, a creation of this team is very important such as choosing the right person to manage and disseminate information. There are a lot of criteria in choosing the person. One of this is the knowledge and skills on the technology that will be used in the entire implementation of the project or program. Individuals who are adept with various types of technologies and willing to be trained again and again just to ensure that there will be no problems later on in the implementation.   Individuals who have lots of connections and networks that can assist them with their problems in terms of technology. Individuals who are willing to share later on their knowledge and not be tacit about the new information and studies so that there will be transfer of skills., and someone that cannot only design programs but can facilitate information flow and sharing of knowledge. a. What communication channel(s) would you recommend for the initial meeting? For the initial meeting of the team, it would be best that is done face-to-face. This is the first meeting so it should build rapport with each other. Even if there are the use of technologies later on, at least during the initial meeting and introduction of each other there already a communication among them. b. What communication channel(s) would you recommend as key interactions (you are not limited to those channels listed in the exhibit)? Later on, after the initial meeting the team can discuss issues through teleconferencing, phone calls, chat messengers and among others that might not require the presence of each other and spend costly fares just to be in one place. Organization of the issues beforehand is also important because this will identify how urgent the meeting should be or is it just one of the meetings and phone calls would be enough. c. Explain how these teams will meet the challenges of each of the stages of group/team development. Engaging in this kind of set-up, virtual self-managed team, is difficult to maintain though. It will require energy because this does not only entail communication but it also needs feedback and learning (source) among the team members. In order to meet these challenges there should be a constant communication even it is called â€Å"virtual† because through this monitoring can be done as well as learning along the way. d. What challenges does diversity present? What must be done to meet these challenges? Diversity in people is very challenging. Every person has its own personality, culture and attitude. Constant learning through trainings can be a good answer to it. e. From a communications point of view, what are the advantages and what are the disadvantages of virtual self-managed-teams? Virtual self-managed team is cost-effective. The only costs that will be incurred are the gadgets that will be used during the networking and conferencing. It can also be done anywhere and anytime of the day. Just put the set up and voila there will be a meeting in the middle of beach. On the other hand, it has also disadvantages. Since it will not require the presence of the person it does not nurture a relationship and does not build rapport among the team. Oftentimes than not, the reaction and the feelings will be not be felt if it is only in the monitor or phone calls. Conversations can be faked and might build walls.

One Sheep, Two Sheep, One Fish, Two Fish . . .

One Sheep, Two Sheep, One Fish, Two Fish . . . One Sheep, Two Sheep, One Fish, Two Fish . . . One Sheep, Two Sheep, One Fish, Two Fish . . . By Simon Kewin What do a sheep, a cannon and an aircraft have in common? The answer is that they all usually use the same word whether they are in the singular or the plural. If you have one sheep and then you acquire a second sheep, you now have two sheep, not two sheeps.   Other words exhibit this strange behaviour too, often other sorts of animal. For example, bison, deer, moose, pike and swine all usually use the same word for their singular and their plural. So, strictly speaking, it would be incorrect to refer to several bisons, deers, mooses, pikes or swines.   I say usually because this rather illogical rule is quite commonly broken and more regular plural forms do creep in for some of these words. Its actually quite common for people to refer to cannons for example. The Compact Oxford Dictionary says that the plural of cannon is only usually the same† so that, in fact, cannons is more and more acceptable.   The process has gone further with other words. For both salmon and trout, for example, the OED now says that either form of plural is equally acceptable. You can say three salmon or three salmons, although many people would still find three salmon preferable. Similarly, the Merriam-Webster dictionary lists both deers and pikes as acceptable plural forms. The Compact Oxford Dictionary, meanwhile, still says that the correct plural for the word pike (meaning the type of fish) is pike. But, as if to illustrate how illogical this is, the plural of the word pike when it refers to the weapon is regular : pikes.   This is another area where there will be disagreement among writers. On the one hand, â€Å"two cannon† is strictly correct but, on the other hand, â€Å"two cannons† is now a common usage and one which is, after all, perfectly clear in its meaning.   Footnote : fish and fishes is an interesting case. Both the Oxford and the Merriam-Webster dictionaries say that the plural of fish can be either fish or fishes. In fact, the two plural words are often used to refer to different things. As the Oxford dictionary explains :   The normal plural of fish is fish, as in â€Å"he caught two huge fish†; however the older form fishes is still used when referring to different kinds of fish: â€Å"freshwater fishes of the British Isles†.   So you use fish when referring to more than one fish of the same type and fishes when referring to multiple fish of different types.

If there are no trees, it would further lead to decrease in the number of animals as it is their natural habitat and cannot be replaced by anything else. No trees means no rainfall.

Ratio Analysis Essay Example | Topics and Well Written Essays - 750 words

Ratio Analysis - Essay Example Suppose we want to assess the financial health of a very large or small firm, how can we analyze the firm so our analysis can provide an insight into the basic prospects for profitability of a firm? Is the firm losing or is it profitable? Are there prospects for making the firm profitable? Is the firm worth buying? Should we sell the firm? If we are to sell the firm, at what price should our purchase price be? How large are the firm’s debts? What are its prospects for profitability? What is the firm’s net worth? These are some of the questions in which ratio analysis can help provide an answer. Gibson (1982, p. 18) pointed out that the financial â€Å"ratios can be grouped into four categories: liquidity, debt, profitability, and other† financial ratios. The liquidity ratios include the working capital ratio, and the current ratio (Gibson 1982, pp. 18-19). Some of the broad debt ratios include the debt-to-capital and the debt-to-equity ratios. The debt-to-capital ratios used by many firms include the long term debt-to-long term debt plus stockholders’ equity, short term debt plus long-term debt-to-short term debt plus long-term debt plus stockholders’ equity, and several other ratios (Gibson 1982, p. 22). ... It also plausible that ratios can be devised based on one’s objectives although there are financial ratios that are conventionally or more popularly used to assess firm performance and status. As pointed out by Gibson (1982, p. 22), for example, â€Å"firm executives have many different opinions on how a firm debt position should be determined from the balanced sheet.† Profitability ratios include measures for earnings per share, return on equity, profit margin, return on capital, return on assets, gross margin, pre-tax margin, and operating margin (Gibson 1982, p. 23). Each type of ratio on profitability can include several specific types of measures. For example, the specific measures or ratios for profit margin include net income-to-sales, income from continuing operations-to-sales, income before minority share-to-sales, net income-to-total revenues, income before extraordinary item-to-sales, income from continuing operations and before extraordinary item-to-sales, a nd income before cumulative effect of change in accounting principle-to-sales (Gibson 1982, p. 24). The tone of Gibson (1982) indicates that a financial analyst may improvise ratios or measures as long as they are helpful to analysis but there are ratios that are conventionally or more popularly used by analysts for assessing liquidity, profitability, debt, or other aspects of firm or business operations. The formulas of the more popular ratios are contained in financial and accounting textbooks. Meanwhile, the ratios identified by Gibson (1982) for drawing insights on firm or business operations include dividend per share, book value per share, effective tax rate, dividend payout, price earnings ratio, and labour per hour. However, surely there are other measures that can be developed depending
