Extinction On Dinosaurs :: essays research papers

Theories of the Extinctions of the Dionsaurs: Dinosaurs became extincted 65 million years ago, at the end of the Cretaceous period, something so devastating that it altered the course of life on earth. It seems like it happened so sudden, as geologic time goes, that almost all the dinosaurs living on earth disappeared. So how did these dominant creatures just die off? Was it a slow extinction, or did it happen all of the sudden? These questions bring rise to many different beliefs on how the dinosaur disappeared over 65 million years ago. Extinction is when the birth rate fails to keep up with the death rate, it is called extinction. But, the definition does not answer the question about the nature or causes of extinction. Paleontologists generally divide extinctions into two types, for that of different causes arose. The first is called background extinctions, isolated extinctions of species due to a variety of causes. Included is out competition, depletion of resources in a habitat, changes in climate, the development or destruction of a mountain range, river channel migration, the eruption of a volcano, the drying of a lake, or the destruction of a forest, grassland, or wetland habitat. The second type of extinction is called mass extinctions. Large numbers of species go extinct; many types of species go extinct; the effects must be global, and the effects must occur in a geologically short period of time.1 The dinosaur could not have lived for ever. No creatures, no plants, no tiny bacteria are forever, not even Homo sapiens. Extinction is the fate of all species. One theory on how the dinosaurs became extinct is that of carbon dioxide, and the greenhouse effect. Volcanoes produced the proposed conditions. A massive volcanic eruption could have saturated the atmosphere with carbon dioxide so that it caused a sharp rise in temperatures worldwide. The excessive carbon dioxide would have permitted solar energy to enter the atmosphere but would have blocked the radiation of most surface heat back out into space, therefore causing the greenhouse effect. Rising temperatures could have killed off or reduced the activity of plankton, disrupting food chains and also messing up the plankton's normal role in converting carbon dioxide to oxygen through photosynthesis. From there it would not have been long for all the dinosaurs to have been suffering, and then to become extinct. My theory of the extinction of the dinosaurs is the theory of the comet

Seatbelts :: essays research papers

When travelling at slow speeds in your car the wearing of a seatbelt has little effect of your body when you brake. So why is it important to wear your seat belt? A driver or passenger travelling in a car is moving at the same speed as the car. If the car suddenly stops, the body of the rider inside will keep moving forward at the same speed. This demonstrates inertia. The tendency of a moving object to keep moving, or of a stationary object to remain at rest. Basically Newtons first law; that a body stationary or moving with constant velocity will want to continue to do so, unless acted on by a force. Lets understand what is happening here. First drive along in your car at 60 km/h on a backstreet with no traffic, then brake gently and slowly. You will notice that the seat belt doesn’t really do much to hold your body. Now do the same again but this time break as quickly and sharply as you can. Your body will be thrown forwards with great force, and your seatbelt will be literally holding you in place. Now your body was what is commonly referred to as being "thrown forwards", however this is not the case. Your body was actually not slowing down much at all and your velocity relative to the car initially was much greater. The car began to slow down due to breaking and your body in accordance with Newtons First law wanted to continue to move at the original constant velocity. Now if your seat belt was not there to provide an opposing force, to your momentum and inertia, by holding you from going forwards, you very likely would have been thrown into the dash or steering wheel. Lets look at this mathematically. m= your mass in kilograms for this purposes 70kg V= final velocity 0 m/s U= initial velocity 60 km/h or 16.6 m/s straight line S= distance taken to stop 42 m t= 3.8 a= -4.368 m/s/s Now your momentum at 60km/h is P=MU So P= 70kg*16.6m/s P=1162 Kg m/s Impulse I=MU/t I=70*16.6/3.8 I=305N So your body will weigh about 610kg when you are breaking hard, a force it is difficult for any person to withstand. Now in the context of a head on accident at around 60km/hr the force exerted on your body is greatly increased. In the event of such an accident it will take the car approximately 0.4 seconds to stop.

Sociology reserch project paper - Essay Example For this particular research, the focus of ethnographic study shall be better insisted on the people living in Rocks Australia (Erickson, et al, 2000). The researcher intends to find out how the location and history of Rocks Australia affect the way of living of the people residing in it and the perception of the people who are simply visiting the place. Through the application of a collaborative research approach, the researcher of this ethnographic presentation intended to see the different features of Rock, Australia itself and that of the people residing in it. Through the collaborative research approach, the researcher and his colleges were able to establish a particular standing in the process by which they attain to create a more significant distinction towards the originality of the culture and the traditions that the society living in Australia is practically living in (Fine, 2001). The basic features of this methodology is that of the process by which the researchers themselves would have a first-hand observation of the ideal matters that creates and further recreates the lives of the people within their communities (Miller,2002). The researchers have practically seen the effectiveness of this methodology as they consider the need to make a practical observation on the society, its location, its build-up and other elements that makes it up so as to be able to particularly identify the instantaneous consideration that is needed in identifying the people of the area and how they are living or even possibly how their ancestors have lived before in connection with the present living situation of the people.

The main aspect chosen is derived from the symptoms of dyslexia. The major symptom analysed was learning difficulty. The underlying assumptions about the character, pervasiveness and materialization of the condition were considered (Reid, 2011). The manifestations characterizing dyslexia supported in the research in relation to reading and learning difficulties were as follows: the reading disability included categorical difficulties with reading speeds and understanding levels. The other aspect included spelling difficulties that further influences reading glibness and written expression. Dyslexia may occur in segregation or may overlap widely in persons with reading problem. The condition quite often exists in persons with abilities, talents and gifts that enable them thrive in many realms. The affected persons portray problems with attention and memory, which makes it difficult to develop intellectually (Reid, 2011).

In the class, it is important to check if the child correctly writes down exactly what is required in the homework (Shaywitz, 2008). All academic work should be written down and not verbally, to help

Automotive Vs. Computers Essay Example | Topics and Well Written Essays - 1000 words

Automotive Vs. Computers - Essay Example The paper is going to focus on Toyota and Dell as the products of these industries. Toyota has in the past been depending on its o its major supplier in Japan. However, Toyota being the current leading automotive supplier of cars in the world embarked on a competitive strategy that involved the production of quality cars hence utilized a reliable approach. In addition, Toyota’s supply chain called for responsiveness and efficiency. Moreover, its supply chain necessitates decentralization therefore many production units in various locations all over the world. However, these decentralized units must also the interlinked. This ensures that information flows consecutively throughout all available units. In fact there are four key feature of Toyota’s supply chain. These features include, inventory, transportation, facility and information. Therefore, it is prudent to conclude that Toyota involves numerous production plants; a number of storage facilities, a well-defined tra nsportation mechanism, and reliable information relaying procedures. ( Dudovskiy). This chain ensures that the end consumer gets a quality product and on time regardless of their location since decentralization takes care of it. On the other hand, Dell relies on an exceptional supply chain whose strategy depends on information gathering from its large customer capacity. As such, Dell uses a direct- sale strategy and the information attained are passed on to both the sales and the procurement sections in addition to its external suppliers. The advantage of an information approach strategy is that it allows for timely supply of the product. More so Dell has identified two channels, through which information is acquired such as amongst the customers and the sales personnel’s, and equally, amidst the sales, procurement and suppliers departments. Hence, this approach has helps the company to sell its products in large quantities and with required quality since there is information flow (Gilmore). The automotive industry can be said to stick to its unique supply chain because of the nature of its product. Automotive is bulky, this makes expensive to assemble in a single location. Moreover, car models are rigid to change because there are a variety of models that a customer can chose from. More so, car parts are expensive to make hence changing any part will most likely result to recalling all previously produced vehicles. Therefore, an automotive industry remains competitive only if it produces different car model that suits the needs of its many customers. In addition, the quality, engine performance and fuel consumption are the factors that customers are after in any car mode. Therefore it is only through decentralization that an automotive producer can understand well the needs and requirements of the market. On the contrary, computer producers are better place to use an interactive supply chain approach because their products can be produced from a central location and easily transported to the consumers. Hence, such compa nies will invest more in both the sales and procurement teams to get the market requirements and they will deliver easily on such demands. Consequently, this is an industry that deals more with technology hence they are aware that technology is dynamic. When it comes to the product, the producer mainly evaluates the production cost. In this regards, automotive produce
