Global Warming Essay Example for Free

Global Warming Essay One of the biggest problems facing the world today is global warming. Many scientists believe that our production of carbon dioxide and other greenhouse gases is having a heating effect on the atmosphere, and this could be very dangerous for human life. This essay will examine the problem of global warming and suggest some ways of solving the problem. Many problems could result from global warming. One of the biggest problems is rising sea level. This could result in the flooding of low lying coastal areas and cities, such as Egypt, the Netherlands, and Bangladesh. Some countries might even disappear completely! Another problem caused by global warming is changes in weather patterns. Many areas of the world are experiencing increased hurricanes, floods, and other unusual weather. A third problem associated with global warming is the effect on animals. Fish populations could be affected, while some insects which spread disease might become more common. There are several things we can do to solve the problem of global warming. One solution is to stop producing C02. We can do this by switching from oil, coal and gas to renewable energy. Another solution is to plant more trees. Trees absorb carbon dioxide and produce oxygen, which is not a greenhouse gas. A third solution is to use less energy and to recycle more products. Generating electricity is one of the main sources of carbon dioxide. If we use less electricity, we will produce less C02. In conclusion, if we make small changes now in the way we live, we can avoid huge changes in the future. Scientists, governments and individuals must work together to overcome this threat.

Peking man Essay Example for Free

Peking man Essay The theory of evolution is backed up by fossils of the ‘Peking man’ found in China during the early twentieth century. The current human species is believed to be the descendant of the Homo erectus, our predecessor species with a smaller brain and upright stature; the Peking man is a subspecies of this group and the corresponding fossil remains were estimated to be nearly 550,000 years old. However, recent Chinese fossil findings conducted by Nanjing Normal University in 2008 suggest the age of a Peking man skull to be at least 750,000 years old. The Homo erectus species is believed to have migrated from Africa approximately 2 Million years ago to Asia. The new estimated age of the Peking man fossils puts forward the possibility of two different subspecies having settled in different parts of Asia during the same timeline. The Homo erectus species had inhabited China and other parts of Southeast Asia for over half a million years. According to University of Iowa’s Russell Ciochon, the Peking man is likely to have coexisted with other Homo erectus subspecies; while one group of Homo erectus is assumed to have settled down in subtropical areas of Zhoukoudian in China, the unfamiliar weather could have driven the other group Southeast which could have evolved into what we today refer to as Peking man (Handwerk 2009). Ciochon uses the phrase â€Å"fork in the road† as an analogy to explain this situation (Handwerk 2009). This subspecies is assumed to have possessed the ability to make tools out of stone and walk upright. Also, its brain size being almost 75% the size of a Homo erectus makes it’s the closest descendant to human beings. The other group of Homo erectus settled in Zhoukoudian is believed to have enjoyed a good supply of food and familiar environment, giving rise to the subspecies Homo erectus pekinensis. The earlier timeline would also mean that this subspecies lived in a more pleasant climate in the grasslands. Moreover, fossil evidence of animal bones indicates that this group of Homo erectus settled in China consumed meat. This inviting proposition of food and pleasant weather could have given raise to the early Homo sapiens to migrate from Africa to Asia. Homo sapiens are quite different from Homo erectus since they are marked by a more â€Å"rounded skull, divided brow ridge, and chin† (Platt 2008). One school of thought spearheaded by Hou Ya-mei of Institute of Vertebrate Paleontology and Paleoanthropology points out the possibility of modern Homo sapiens coexisting, interbreeding or even fighting with Homo erectus, thereby observing the theory of ‘survival of the fittest’ in action (Platt 2008). The present human race is believed to have originated out of Africa 60,000 years ago. The differences in Homo erectus fossil patterns in Asia and other parts of the world had given rise to discrepancy, which can be explained by a â€Å"secondary migration from Africa† (University Of Cambridge). Even though this theory makes sense to an extent, Susan Anton of New York University is pessimistic about the supporting data given to back up claims of two separate settlements of Homo erectus. She simply mentions the possibility of any number of migrations can be claimed, but those claims will continue to be void without strong supporting evidence. She furthers states that evidence such as the routes taken by the Homo erectus groups or a central cohesive point of origin in Africa would be needed to connect the â€Å"Out of Africa† theory and these claimed migrations. However, Anton concludes by admitting that this theory and the change in the timeline would help explain why the Homo erectus had persisted longer in continental Asia. Reference Handwerk, B.

System Software And Application Software

System Software And Application Software This term is used to describe programs that enable the computer to work and coordinate the various parts of the computer system to make it run efficiently. It controls the operation of the computer as it tells the hardware what to do and how and when to do it. It is the base for applications software as they cannot work without system software Operating systems are an example of it. The operating system is the program that actually makes the computer works. Application software This term is used for programs that enable the user to do a specific task such as creating a document, producing invoices and using database. It is used once the operating system has been loaded. It can be educational programs, entertainment programs and etc. Operating System It is the software that actually makes the computer work. An example of it is Microsoft Windows, Macintosh Operating system (Mac OS), Linux and Unix. These are some functions of the operating system: Boot up the computer. Control the hardware such as printer, scanner, monitor, keyboard and mouse. Controlling features such as formatting disks, saving files and retrieving them form the hard disk. Provide the base for the applications software to be launched.

What user interface is and examples of it. Now you are ready to know about networks and internet. What a network is, types and advantages of it. Also what an internet is and how it can be useful to users. This will be explained in the next chapter. Chapter 4 Networks Objectives: After completing this chapter, you will be able to: Understand what is meant by a network. Know the advantages of using networks. Distinguish between types of network. Know what an internet is. Identify the advantages of the internet. Understand some of internet and browsing basics. Networks Network is a group of computers connected together via cables or telephone lines or wireless to enable users to share hardware, software and data. Network requires each computer to have a network card. Advantages of using networks Sharing files: You can share files between computers through using networks instead of using a flash memory to send a file from one computer to another. Sharing resources: Through networks, people working in a same place can share printers, scanners, fax machines. This is less costly for organizations with many computer users. Sharing programs: Through networks, People working in the same place can share the same program instead of purchasing individual program for each one. Communication: Users on a network can communicate with each other by e-mails even if there is no internet connection. Types of networks There are three types of network which are: Local Area Network (LAN). Wireless Area Network (WLAN). Wide Area Network (WAN). 1. Local Area Network (LAN) A LAN is a system where computers are connected together within a company or organization to enable people share files and resources such as printers. A LAN can be within the same building or within a group of buildings close to each other. 2. Wireless Local Area Network (WLAN) Computers are connected together through high frequency radio signals. They are used in many office buildings, coffee shops and even at homes. No wiring is required between the computers and the peripherals (peripheral device is any device that can attach to the computer such as speakers, printers and scanners). 3. Wide Area Network (WAN) Computers are connected together over a wide area such as between towns or countries. Communication between computers can be done through telephone lines, fiber optics and radio links or satellites. The internet is an example of it. Client / server computers A client computer is the computer that needs data from another computer known as a server. The server is a powerful computer than client computer in terms of data storage and processing speed. Activity (4-1) Objectives: Understanding what a network is. Identifying the advantages of using networks. 1. Complete the following sentences Network is †¦Ã¢â‚¬ ¦..†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦..†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦..†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦..†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.

Which type of network is the internet? Internet The internet is a global network of interconnected networks around the world. The best thing about the Internet is the amount of information that you can access from it. The internet is not the same as World Wide Web (WWW) as the internet is the network but the World Wide Web is a vast collection of linked documents held on computers all over the world and can be accessed using a web browser. Web browser is software that is used to retrieve and display contents on the World Wide Web, including text, image, video and other types of files. The Internet Explorer and Firefox are an example of it. advantages of the internet Using the internet has many advantages and here are some of them: Researching tool: Find any information the user need through using search engines. Search engines are the web pages that search for information on the internet (e.g. Google, Yahoo). Marketing tool. Method of communication with others through chatting programs and e-mails. E-mails mean sending and receiving messages through the internet and the messages can include text, images, video files and sound files. Entertainment tool (e.g. playing games, listening to music and watching films and video clips). Information is available 24 hours per day and 7 days per week. Services: Many services are available through the internet like shopping, hotel reservations and paying pills. E-commerce: Doing business, selling and buying products and services through the internet. E-learning: Using the internet for education. Downloading software from the internet. Download and upload Download means to transfer data from a server to a local computer while upload means to transfer data from a local computer to a server. Examples: Download programs, songs and games from the internet to the computer. Design a website then upload it from the computer to the internet to be used by others. Transfer rate Data is transmitted in collections of bits or characters. The transmission speed of data is measured by the Baud rate which means how many bits can be transferred each second. Bps: It means bits per second. 8 bits = 1 character. Kbps: It means kilobits per second (i.e. 1000 bits per second). A 56.6Kbps modem technically transmits 56,600 bits per second of data. The modem is a device that allows computers to transmit data over telephone lines. mbps It means megabits per second (i.e. 1,000,000 bits per second). Internet connection services Computers are connected to internet in many ways. Here are the types of connections: Dialup connection: It uses telephone lines to connect to the internet. A modem is used to dial a telephone number and connect to an Internet service Provider (ISP). This type of connection is inexpensive compared to other connections. The phone line is busy when the user uses the internet, meaning the user cannot make or receive calls when he is online. Data transfer over dial-up is slower compared to other connections. Internet Service Providers (ISPs) are companies that allow the users to connect to the internet. Broadband connection: It allows faster transfer of information. This type of connection is available through a phone line (ADSL), cables, satellite, mobile phone and wireless networks. Asynchronous Digital Subscriber Line (ADSL) broadband: It uses a modem and the telephone line system to connect a computer to Internet. The ADSL modem is different from a dial-up modem. Through ADSL, a user can make calls and use the internet at the same time. ADSL connection is faster and expensive than dial-up connection. Wireless broadband: It uses radio transmitters and receivers to connect computers. Many public areas and organizations provide this connection which is known as Wi-Fi. Nowadays this connection is used at home and supported by many phones. Cable broadband: It uses a modem and the cabling infrastructure used for cable TV to link a computer to Internet. The cable modem uses the same cabling infrastructure and connection to your home as cable TV. The cable modem connects to the computer by a local area network (LAN) card. Cable connection is faster than dial-up connection and the cost of it is similar to an ADSL connection. Satellite broadband: It is an Internet connection that requires the installation of a special satellite dish. Activity (4-2) Objectives: Understanding the difference between internet and World Wide Web. Identifying the advantages of the internet. Knowing some internet terminologies. Differentiating between dial up connection and broad band connection.

Television Programs :: Personal Narrative Media Entertainment Essays

Television Programs Nature. PBS. 2004. Orangutans: Just Hangin’ On. When I was nine years old, my family lived in Ayer, Massachusetts. I was sad to leave my friends in Colorado behind, but luckily lived on a street with a lot of other kids that I became fast friends with. There was a military base located in the town, so it was not unusual for new transplants to come in and out of the school throughout the school year. My teacher was fantastic and helped me catch up when it was clearly evident that this school was way ahead of mine back home. Soon I became one of the top students in my class and had made a best friend in the girl across the street. I began to become accustomed to my quaint small town, with the candy store that still sold nickel candies. There was a bookstore that didn't mind if you read the magazines without paying for them, just as long as your fingers were not sticky from your nickel candy. It was one of those wonderful carefree days as a kid that my whole world changed. I had received a scooter for my birthday and rode up and down the streets with my friends on their bikes after school. The next street over from mine had a long winding hill that the daredevil bike riders liked to coast down at what seemed at the time to be as fast as a car. After riding around my much more level street, my friends became bored and wanted to test it out. I was not the most balanced of creatures on my scooter, and I wimped out. We decided that they would go down the hill and then meet me back at the old school that was next to a large field across the street from my house. The school was from the nineteenth century. There had been a fire there that shut the school down, but amazingly had not caused any structural damage to the outside. It was deemed an historic building so it remained preserved. It was kind of creepy to look in to its abandoned insides, but there was a large asphalt lot behind it and the field next to it, so the former playgrounds received a lot of attention from the kids in the neighborhood. I rode my scooter down towards the back of the school to where a basketball hoop stood and leaned my scooter against the chain link fence.

Overview of Autism Essay -- essays research papers

Autism is defined as a developmental disability of the brain. However it is not a form of mental retardation. A person with autism can actually be very intelligent. Autism develops before a child is 30 months of age. It occurs is approximately 4 out of every 10,000 children. Children with autism are unable to develop normal relationships with others. Their hearing and sight senses are heightened. A noise that would not bother a normal person might drive an autistic child crazy. They have a difficult time understanding what is going on around them. If something suddenly happens, like someone laughs or cries they go into confusion because they are wondering why this is happening and they might go into panic. Sometimes they may lose their ability to speak, or need extra time to respond to a question. It is sometimes difficult to tell whether a young child or infant is autistic. Some of the symptoms vary greatly but follow the same general pattern. Autistic infants will act relatively normal during their first few months. But after a couple of months they become less responsive to thei...

Grammar and the Role of Writing Center Tutors as Teachers of Grammar :: Teaching Writing Grammer Education

Grammar and the Role of Writing Center Tutors as Teachers of Grammar Communication in any form requires a protocol. The evolution of language from sounds into words is proof of that. People recognized that in order for two people to understand each other, they must have a common code that will allow each one to transmit and receive signals accurately. If the word â€Å"red† signified two different colors to two different people, for example, then there would be a breakdown of communication. Language has grown complex over time and in its current form, it enables users to communicate with precision and nuance. In the English language, specifically, the meaning of what is communicated depends not only on the words chosen, but also on where those words are placed and how they are modified. Semantics studies meaning and interpretation of words. This is separate from syntax, which deals with the physical location of a word (or other element of language) within a sentence (or other linguistic construct). Today, we usually use â€Å"grammar† an d â€Å"syntax† interchangeably, although syntax is a subset of grammar. Within the context of Writing Centers, this is acceptable, because when the issue of grammar comes up, it is always a matter of syntax; we never, for example, deal with phonology, which is also a subset of grammar. However, semantic issues are sometimes labeled grammatical issues, which is not correct. One might argue that what we call these issues does not matter so long as they are dealt with appropriately. In truth, it does matter, because by lumping semantic issues together with syntactic issues makes grammatical issues as a whole a larger issue, which is undesirable because grammar is already a much feared and religiously avoided area. I imagine a small, dark closet labeled Grammar, in an obscure part of the house that represents all the issues that Writing Centers deal with. Into the Grammar closet, students and tutors alike throw in several issues—actual grammar, but also semantics and mis cellaneous quirks of the language—and then shut the door. Over time, the inside of the closet becomes dusty and obscure, inaccessible as well something to be both feared and ignored. Come spring, nobody wants to be responsible for cleaning the grammar closet. Sadly, with the desire to focus on critical thinking in papers (i.e. content), those who plan Expository Writing classes or provide tutoring for it have gone from saying, â€Å"Critical thinking is the primary focus† to saying â€Å"Critical thinking is the only focus.

Automotive Essay

Q 1, How well is â€Å"Jones Electrical Distribution† performing? What must Jones do well to succeed? First Quarter 2004 2005 2006 2007 Sales increase 18% 17% ROE 7.6% 13.6% 12.3% 2.0% Sustainable growth rate 7.6% 13.6% 12.3% 2.0% Profit Margin 0.9% 1.5% 1.34% 0.8% Assets turnover 2.76 2.88 2.86 0.70 financial leverage 3.20 3.12 3.23 3.49 Shareholder’s equity 31% 32% 31% 29% From coverage ratio analysis we can see Jones electrical distribution’s business is stable business as a retailer. Sales increase 18% and 17% in 2006 and 2007 respectively, with estimation in 2007 will be 20.4%. Shareholder’s equity is around 30%. Jones sustainable growth rate: g*=RT*ROA, so compare with actual sales growth, we can make the conclusion Jones well managed its growth through year of 2004 to 2007. As Jones doing low margin business, so should avoid high financial leverage ratio as interest burden will be heavy. Q2, why does a business that has profit of $30,000 per year need a bank loan? 2004 2005 2006 First Quarter 2007 collection period 42.0 days 44.0 days 43.0 days 43.9 days payables period 10.1 days 10.0 days 24.1 days 37.4 days From above table we can find out Jones collection period increased step by step and this will need more cash support that, payables period exceed 10 days from 2006, this will lost 2% discount from suppliers. As Jones sales growth rate is high than sustainable rate, so its net earning could not support increased account receivable and inventory. Then the company need bank loan to finance the increase business. Q3, What drove the increase in Jones’s accounts receivable and inventory balances in 2005 and 2006? Sales growth drove the increase of accounts receivable and inventory balances in 2005 and 2006. Q4, Is Nelson Jones’s estimate that a $350,000 line of credit is sufficient for 2007 accurate? As Jones estimated growth rate in 2007 is 20% for sales, so account receivable and inventory will increase as a consequence. Total $129,000 is needed if collection period and inventory will not improve. As Jones accounts payable in first quarter exceed 37 days already, this will makes Jones loss 2% discount from suppliers, accumulated 24% against 7.5% interest rate. So this makes sense for Jones get loans build inventory within 10days payment. Total inventory change $129,000+$120.000=$249.000. So $350,000 line of credit is sufficient for 2007 even the bank set some limitations how to use the credit. Q5, When will Jones be able to repay the line of credit? As long term debt already $378,000 in first quarter of 2007, plus additional bank loan $350,000. So total credit will be $720,000 Net income for Jones is $30,000 and with stable growth rate, so Jones need around 25 years repay all the credit. Q6, What could Jones do to reduce the size of the line of credit he needs? Jones should manage closely reduce collection period and increase inventory turn over to reduce work capital.
