Gender- Prevalence of Kidney stone was significantly higher in urban area than in rural area. 73 % of men and 29 % of females were suffering from kidney stones. Furthermore, the prevalence ratio (male: female) for Kidney stone was 2.51:1. Prevalence for men patient was observed more in age group of 30-40. However nearly similar incidence were observed in 40-50 and 20-30 age group also. However now a day incidence of stone is increasing in younger age group also as per physician comment. Same…

Chasing Corals Essay Chasing Coral is a 1 hour 33 minutes documentary directed by Jeff Orlowski following a group of photographers and scientists as they attempt to capture the processes of coral bleaching. The plan is put together by Richard Vevers, a reef surveyor after he himself observes the effects of bleaching on a reef he recently surveyed. After teaming up with Trevor Mendelow, Zachary Rago, and other scientists, they plan to rig time lapse cameras in areas of reef, although Nature has…

The earth is reliant on various reproductive biochemical cycles, to maintain balanced and regulated conditions on earth and within the atmosphere (Name, date). These cycles include the carbon, nitrogen and hydrological cycles. These cycles among others, bring with them various geological, chemical, physical and biological processes (name, date). All these cycles are interconnected; matter within them is continually cycled between biotic and abiotic parts of the environment (name, date). Without…

colorless, crystalline, inorganic compound that forms the toxic fumes produced when cadmium oxides are heated. It is an odorless white solid that is more dense than water. Cadmium nitrate is prepared by first dissolving the metal cadmium or its oxide, carbonate, hydroxide in nitric acid them immediately…

INTRODUCTION Lead is a bluish grey metal ,which is one of the useful and common metal that has been used by humans for over 6000 years1 it has high density ,ductility, poor electrical conductivity and more over which is soft and highly malleable in nature. these all properties were helping the early extraction and working with lead and makes it more popular among industrial and other mankind usages all over the world . Several millions of lead are consumed by world for the production of…

Case study of X-ray imaging with grating interferometer on pearls Abstract- With the increase of fraudulent conduct in the field of jewellery there has been increase in the demand for inspection to identify the purity of the product. In this case study X-Ray Radiography is used to identify natural pearls and artificially cultured pearls. In order to understand the internal structure a personalized grating interferometer and inspection has been performed to obtain measurements. The computed…

South Africa is surrounded by three major oceans namely the Atlantic, the Indian and the Southern Ocean. The west and east coast of South Africa are geographically and oceanographically distinct, supporting a wide variety of marine life. The west coast of South Africa is characterised by the relatively cold, slow-moving Benguela Current. The marine life along the west coast is adapted to colder temperatures. The waters of the west coast are nutrient-rich and support a large abundance of fish.…

Global Weirdness is a relatively easy read that is focused on the effects of global warming. The title “global weirdness” is incredibly appropriate for it is not just about global warming, but also the other “weird” factors that are occur as well; for instance, relentless droughts, rising seas, severe storms, deadly heat waves, and water movements are just a few to name. The book is consisted of four parts with sixty, short chapters and an epilogue. The first part is entitled “What the science…

Discussion of Results During the first week the goal was to determine the unknown compound. In order to determine the unknown compound, many tests were performed testing the solubility, pH level, conductivity, cations present (flame test), and the anions present in the compound. The anion test had positive results for the sulfate test due to the formation of a white precipitate, indicating the presence of a sulfate ion. For the sulfate test the unknown solution, potassium sulfate, and combining…
