Before the 1950’s anxiety was mainly treated with barbiturates and meprobamate. However‚ these drugs have disadvantages linked to dependence and abuse. Consequently‚ there was a need for new medication with fewer side effects [1]. In the 1950’s‚ Sternbach‚ a chemist at Roche‚ started looking for a new anxiolytic. He started this process by using benzheptoxdiazines‚ molecules which he had previously worked with. He synthesised new compounds using his key product and secondary amines. After having

New York: Rosen Pub Biodiversity and its decline is a subject often overlooked when talking about the dangers facing our planets ecosystem. A main reason for this seclusion is the vague nature of the word biodiversity. It is a term that has so many different meanings because of people’s different subjective interpretations. However at the Convention on Biological Diversity at Rio de Janeiro‚ Brazil in 1992‚ the term was

Terrestrial Biodiversity of Mauritius 2.1 Overview of Biodiversity Mauritius has an area of 1‚865 km2‚ of which 30% is considered forested. The area of good quality native forest‚ (i.e. that with more than 50% native plant cover‚ Page & d’Argent 1997)‚ is estimated to cover less than 2% of the island (NEAP 1999‚ MWF unpublished‚ Fig.2.1). The rest consists of plantation forestry‚ deer-ranches or highly degraded vegetation invaded by alien plant and animal species. As a result Mauritian biodiversity is amongst

Biodiversity is the degree of variation of life forms within a given ecosystem‚ biome‚ or an entire planet. Biodiversity is one measure of the health of ecosystems. Life on Earth today consists of many millions of distinct biological species. The United Nations declared the year 2010 as the International Year of Biodiversity. Biodiversity is not consistent across the Earth. In the terrestrial context for example‚ tropical regions are typically rich whereas polar regions support fewer species. Rapid

Biodiversity is the variety of all life forms including animals & plants that can be found either in just one location or across the entire country. The ways you can identify a healthy creeks is see if it has a good amount of biodiversity. The second most important part is the monitoring of the creek‚ which is done by running tests similar to what we did
