The purpose of this experiment was to understand kinetic and potential energy and verify the Law of Conservation of Energy. Kinetic and potential energy are both forms of energy that usually coincide with each other; potential energy usually changes into kinetic energy and vice versa. While potential energy results from an object’s position or arrangement of parts, kinetic energy results from an object’s motion. Together, the sum of an object’s kinetic energy and the potential energy at that…
I. INTRODUCTION The performance of present computing systems has increased at the cost of considerably enlarged power consumption. The increased power consumption either reduces the operation time for battery powered systems, such as hand-held mobile systems, or generates extreme amount of heat and requires expensive sophisticated packaging and cooling technologies, especially for complex systems that consist of several processing units. The generated heat, if not efficiently removed, can also…
Figure 21: Dependence of the penetration depth on dwell times for different indentation peak loads Figure 22: Dependence of the penetration depth on dwell time for different indentation peak loads in ln-ln plot 5.4 HV vs. penetration depth Figure 23 shows the dependence of the Vickers hardness on the indenter penetration depth for 100mN to 1000mN and 10 s to 60 s dwelling time. The highest hardness value is 15.6GPa. As the indenter penetration depth increases, the hardness value decreases.…
endangered/threats include habitat loss. It is estimated that between 1970-1983, the Amur leopard lost an 80% of its territory. They will have nowhere else to go. deforestation cutting down trees, Poaching illegal trade, prey being taken by humans for farming. conservation for farming, Vulnerable population size and inbreeding. Because the amur leopard is so endangered it its at risk of going fully extinct. However not all of their habitat is lost. Large parts of forest which are…
In the column, “The Case For Closing The Honolulu Zoo,” Bob Jones addresses the issue of Honolulu Zoo’s problems regarding its budget and attendance rates, informing the audience of the controversy behind using the taxpayers money to maintain the zoo’s facilities and such. The purpose of this column is to argue that the $7 million dollars that are currently being used for the zoo’s maintenance should be used for something that everyone needs, like roads and sewers. While stating his claims,…
sentry duty may be a state-dependent behaviour and that it allows non-sentries to relax their vigilance and forage more. Understanding how captivity affects behaviours like sentry duty is important for conservation, particularly reintroductions. Key words: sentry, captive, meerkats, behaviour, conservation.…
Among the main reasons that lead to poaching, there are the elevated request for wildlife products, poverty, scarcity and unemployment, the improper advantage given to local communities limited by conservation activities, population pressure (OIPA, 2014), and insufficient funds for conservation, corruption and lake of political will. Different strategies can be implemented have been suggested in the NEAP to fight against elephant poaching in Malawi. Firstly, the NEAP stipulates monitoring the…
Trustees of the Davis Conservation Foundation require that you provide a completion report. If the project is not completed within 12 months of receipt of funds, please provide a brief written progress report in the interim. 1. What were your original goals and objectives for this project and to what extent were they achieved? The goal of the project was to hire an intern for the summer of 2016, a student with an environmental focus, to assist with monitoring conservation lands owned by the…
Maisy Berger Is the World’s Most Rare Marine Animal Going to See 2018? Introduction Discovered in 1958, the Vaquita is now a critically endangered species. Classified as endangered by Mexico in 1975 and by the United States of America in 1979, the Vaquita now only has 30 individuals left in their species. These beautiful creatures are part of the porpoise family. They grow to be about five feet and usually weigh around a hundred and twenty pounds. The Vaquita are animals that thrive in a…
Conservation Biology is a vital component of the wildlife and natural resources field of work. Increasingly it has shaped my professional interests and career choices over the last several years as its importance is made clear by mounting threats to biodiversity and ecosystem balance. Without the ideology and practices developed in the field of conservation biology many of the species we consider common today would have easily gone extinct in the early 20th century due to a lack of…
