Human Race And Human Population - 1443 Words

The world is home to millions of species both large and small that are able to thrive perfectly in their environments. All living creatures on this earth contribute in some way to the ecosystem that we all are a part of. Unfortunately, the one species that has the greatest control of the earth is us, the homosapiens. Modern humans began to develop nearly 200 000 years ago and ever since then populations of homosapiens have spread across the entire world. Almost every environment we as humans have come across has in time had to change to try and meet the needs of all the species that populate the earth together with the enormously increased human population. Sadly the human population covers over 80% of the earth’s surface with various†¦show more content†¦However on a human dominated planet, the distribution and populations of large mammals has slowly been declining around the world. Due to this researchers have come to the conclusion sub-Saharan Africa is more or le ss the only place left on earth where there is still a relatively high diversity and population of large mammals. This is not because the continent is naturally rich in large species, but because it is one of the only places on earth where human activities have not yet wiped out these incredible mammals. Sadly the influence of the East namely Korea and China and the United States is decimating elephant, rhino, lion and giraffe. Unfortunately even now, even in our so called technically advanced world there are hundreds of species that are still at threat of extinction because of humans. Animals like the black rhino or the Sumatran tiger plus many more have the status of critically endangered. But it is not all doom and gloom as many organizations like WWF have been working diligently to protect the endangered creatures of the world. For example, the mountain gorillas of Congo Basin have had a population increase of over 700 gorillas since 1989 because of their hard work. So if Homos apiens never existed then the world would be most probably be a very different place and many extinct animals might still be roaming the lands.

The Earliest Signs Of Euthanasia - 1107 Words

Even though people think so, old people should not be euthanized. Old people shouldn’t be euthanized because Colonel Sanders achieved a lot as an elder. People should respect the human life, and know that they still have a life to live. Even though they might not stay up with today’s technology they still live rich full lives. The earliest signs of euthanasia are during the 5th century B.C. This was the time of the Greeks and Romans. â€Å"In ancient Greece and Rome†¦ active euthanasia and suicide had tended to be to be tolerant.† (Historical Timeline) They didn’t seem to find value in individuals but as an empire. So the sick and the weak would have probably been killed so that they could be the strongest civilization. After centuries of killing and assisted suicide came Christianity. It started in the 12th century and it forbids euthanasia. They viewed that â€Å"human life is a trust from God.† (euthanasia.procon). Originally in the U.S. it was legal, but was outlawed in 1828 in New York. Many other of the states and territories followed their example soon after. Even after that another form of euthanasia was still legal, infant euthanasia. But after the 1917 film â€Å"The Black Stork† there was a lot of controversy rather it was ok or not. The film was inspired by a doctor who would convince parents to let a child die who had several disabilities rather have surgery that would have probably saved the child’s life.

Seismic Force Modification Factor

Question: Discuss about theSeismic Force Modification Factor. Answer: Literature Review: From the research (Samantha, 2010)it can be found that the design of a structure can be made cost efficient and at the same time the safety performance of the structure can also be maintained. The elastic behaviour of a structure is expected. It causes a reduction in the design and this seismic force gets influenced by the application of a factor which is known as Seismic force modification factor. It is denoted as R. it helps to simply the designing process of the structure. With the application of R, only linear elastic static analysis is required in a structure. The behaviour of the reinforced steel is capable of controlling the responses of the structural elements of a reinforced concrete that are subjected to the earth quake loading. Therefore, it is very much important to develop an analytical model so that this problem can be avoided. The model must be capable of predicting the primary characteristics of steel. It must be measured within the specified range. The past records or the history of loads must be analysed in order to predict the characteristics and the impacts. If design base shear is denoted by Vt and design seismic force is denoted by Vs, then Seismic force modification factor ( R ) can be obtained with the help of the following equation: Vs = Vt / R Or, R = Vt / Vs According to the research (Adeel, 2009), R factors are known to be very important seismic design tools that can be used in order determine the degree of inelasticity that can be expected in a structure at the time of an earth quake. R factor has the capability to reflect the structure for dissipating energy using the inelastic characteristic of the structure. From the research it has also been known that it is also used for reducing the design forces of a structure. The seismic codes depend on the ductility and reserve strength and suitable seismic code helps to improve the ability of a structure to dissipate and absorb energy (Denis et al., 2003). Seismic force modification factor is also known as response reduction modification factor and according to the research, the value of R can be obtained with the help of the ductility reduction factor and the over strength factor (Adeel, 2009). The over strength factor is denoted as ? whereas the ductility reduction factor is known as R. The R factor can be obtained with the help of the following equation: R = R x ? The values of the seismic force that are used in the design of a structure are generally computed with the help of the diving forces which are associated with the elastic response of the R factor. The R factor is required in order to develop the lateral strength of a structure and also to sustain inelastic deformations i.e. the ductile behaviour of the structure (Adeel, 2009). Therefore the value of the R factor is very important in order to determine the design specifications of the design of the seismic loading. The response modification factor can be obtained with the help of the following expression also (Adeel, 2009): V = 2.5 x ( pga ) x ( W / R ) Or , R = ( 2.5 x ( pga ) x W ) / V Here, V denotes the design base shear. The weight of the structure is denoted by W whereas pga represents the peak ground acceleration. According to the research (Ferraioli et al., 2012) force reduction factor ( q factor ) is the another name of the response modification factor ( R factor ). There are different expressions that can be used in order to calculate R factor. From the research (Ferraioli et al., 2012), it has been found that the R factor can be calculated with the help of the following equation also: R = RS x R x R Here, Rs denotes the strength reduction factor, R represents the ductility reduction factor and R denotes the damping reduction factor (Ferraioli et al., 2012). From the research it has been known that the over strength reduction factor that is recommended by EC8 for a multi story structure is conservative. From the research paper (Ferraioli et al., 2012) it can be found that the beam column joint is very important zone in case of a frame that is capable of resisting reinforced concrete moment. From the research (Adeel, 2009) it has also been found that a structure is influenced from different types of ground shaking. The nature of the shear failure is brittle. The capability of the structural system for resisting the actions allows the design to prevent the seismic forces and also to helps to provide a elastic response. The reduction can be done with the help of the q factor. References Adeel, Z. (2009). Response Modification Factor Of Reinforced Concrete Moment Resisting Frames In Developing Countries.
