g new ideas for keeping things like foodcold. Up until the early 20th century ice was the best method for cooling perishable items, butthen we figured out a more efficient and affective way of keeping items cold. It was called therefrigerator. Soon after the introduction of the refrigerator we developed something calledcryogenic freeing, which is…

The heat gradient of the earth’s surface serves as the driving force for atmospheric circulation (Hodell & Thomas, 2000). The resulting differences in the temperature of different areas also bring forth a variation in pressure. When there is a difference in terms of pressure, air movement is initiated, and thus, wind is formed. Also, since…

Confined spaces are enclosed places that present a danger of death or severe harm due to hazardous substances or dangerous conditions, such as lack of oxygen. These risks often arise from activities like welding, painting, flame cutting, and chemical usage. Construction work, fabrication, or modification can also lead to confined spaces. Examples include chambers, tanks,…

According to UNDP.org (2010), biodiversity plays a critical role in the ecosystem. It encompasses various microbial and animal species, including bacteria, algae, fungi, mites, millipedes, and worms. These diverse organisms are essential for soil conditioning, organic matter decomposition, and nutrient supply to plants. By facilitating the transfer of vital elements like nitrogen, carbon, and phosphorus…

The lake is holding a entire catchment country of 337 km2. out of which Telbal-Dachigham is largest catchment ( 234 km2 ) . which is further divided into the Telbal-Dara ( 89 km2 ) and Dachigham National Wildlife Reserve ( 141 km2 ) sub-catchments. While most of the Dachigham National Wildlife Reserve is drained chiefly…

INTRODUCTION Conventional diesel and petrol are both produced from mineral oil, but using different refining methods. While diesel is in principle easier to refine than gasoline, it needs to be cleaned from more pollutants to ensure that tailpipe emissions remain as low as possible. However, diesel contains more energy than petrol and the vehicle’s engine…

One footprint, one large impact The latest official world population estimates the current population, for mid-year 2009, at approximately 6,790,062,219 (Rosenberg, 2009). From now until the middle of the 21st century, in only fifty years, the world’s population will increase by 50% from 6 billion at the end of 1999 to close to 9 billion…

Enzymes have a critical function in cells as they increase chemical reactions by lowering the activation energy necessary for the reaction to occur. Potatoes (Solanum tuberosum) possess highly efficient enzymes for production, but it is desirable to hinder their activity. By inhibiting the catecholase enzyme in potatoes, the occurrence of browning during cooking can be…

A mid latitude cyclone can also be referred to as an extratropical cyclone. As the name mid latitude suggests, they are found outside the tropics but before the north and south poles, approximately between 23 and 66 degrees on each of the hemispheres or the temperate zones of the earth between the Antarctic and the…

Carbon tax is an environmental tax levied on the carbon content of fuels. It is a form of carbon pricing. Carbon is present in every hydrocarbon fuel , such as coal, petroleum, and natural gas. It is then released as carbon dioxide (CO2) when they are burnt. In contrast, non-combustion energy sources—wind,sunlight, hydropower, and nuclear—do…
