The Arctic’s Iconic Carnivore Abstract Climate change effects on the arctic are now becoming more evident to ecologists. Severe declines in polar bear populations are more noticeable as periods of sea ice cover are steadily declining. A decrease in sea ice is leading to nutritional stress in polar bears due to shorter periods available in prime hunting grounds. As a necessity to the polar bear’s niche a loss of sea ice has harmful implications to polar bear populations. Not only are hunting

have a lasting effect on an ecosystem such as an Arctic Tundra. In the Alaskan Tundra‚ strong and persistent winds rush through the air. These winds desiccate and abrade plant tissues‚ contributing to one of the many factors of why tundras aren’t able to grow trees. Temperature in an arctic tundra is extremely cold. The chilly temperatures prevent many plants from being able to grow in this region. During our northern hemisphere winter‚ the arctic regions of the Earth‚ including Alaska‚ are tilted

biome is characterized by extremely cold temperatures and treeless‚ frozen landscapes. There are two types of tundra‚ the arctic tundra and the alpine tundra . ARCTIC TUNDRA The arctic tundra is located in the extreme northern hemisphere around the North Pole. This area experiences low amounts of precipitation and extremely cold temperatures for most of the year. The arctic tundra typically receives less than 10 inches of precipitation per year (mostly in the form of snow) with temperatures averaging

TESTING AND SPECIFICATION OF DRYMIX MORTAR IN SINGAPORE ABSTRACT Singapore is a small island country‚ but has won renown as uncorrupted government and high quality products. Independent testing and inspection played a very important role for this achievement. The Housing and Development Board (HDB) is the sole public authority in Singapore and was set up as a statutory on 1 February 1960. Within 45 years‚ it built more than 700‚000 flats housing approximately 86% of the population. Every

INTRODUCTION Chapter-1 There many things which make the production of on-site concrete aggravating. Bags of cement‚ sand‚ aggregate and possibly other additives must be delivered to the construction area. A supply of clean water is also necessary‚ along with a rented concrete mixing hopper. Even after all the dusty and heavy ingredients have been loaded into the hopper‚ there may occur the problem of erroneous water-cement ratio. One common solution to this messy and time-consuming

On the one hand‚ some argue that drilling for oil can bring many benefits both economically and politically to America‚ it creates jobs and makes us less dependent on foreign oil. Also in the last two decades their
