Humans are incapable of living without oxygen, so why does it seem logical to cut down our main source of life? Not only are we reducing the oxygen entering the air while cutting down trees, many other negative effects occur worldwide. Deforestation is a permanent destruction of forests to make room for other uses. With it comes many negative effects that hurt not only us but the animal population and the atmosphere. It has been estimated that about half of the world’s forests have been cleared,…

Europe began the initial framing of society. In the early 1900’s, Europe (England&France) colonized and occupied all of the Caribbean islands. Europe looked at the islands as basically money for them; they yielded things that Europeans use in their daily lives and can also make profit of off. In addition to colonizing Caribbean islands, they occupied a few African countries and India. European colonial powers literally used these countries as factories for their own personal benefits. They…

Age of puberty attainment in beef cattle is an important aspect for producers. This is because age at puberty is a key factor for a heifer’s lifetime reproductive performance. Beef cattle management programs aim for heifers to conceive by two years of age, but this can be a challenge when producing Bos indicus cattle. Puberty attainment in Bos indicus cattle is considerably lengthier than Bos taurus cattle, with the age at first calving typically being 40 months or more (Nogueira, 2003).…

Introduction If you wanted to go skiing amongst the aspens and pines, hike in the desert, go to a music concert, or perhaps float in the Great Salt Lake, well, board an airplane and go to Utah. Utah is a state like no other because it boasts everything you can imagine. From luxurious hotels to modest farm houses, urban centers to barren deserts, valleys to mountains, this state has it all. History In 1830, a man named Joseph Smith wrote the Book of Mormon. This book was about…

axis). Neurons of the hypothalamus receive stimulatory and inhibitory synaptic input from virtually all areas of the central nervous system. When the hypothalamus senses a change in homeostasis, a hypothalmic neuron synthesizes and releases the tropic hormone called thyrotropin releasing hormone (TRH). TRH travels down the axon of the neuron and into the axon terminal where TRH is released. Following the release, TRH travels through the hypothalamohypophyseal portal vessels into the anterior…

Harrison Ford: The Star System In Hollywood The Star System in Hollywood is what powers the rise of unknowns into household names and Hollywood fame. The Star, the actor and even the real person all play a role in the success and failure of an actor or actress, personas which in combination will be able to make or break a film before it is even released. Harrison Ford manages this expertly, a rough yet heroic star, a quick witted and dead pan actor, and the actual person hidden away from the…

The second axis that comprises the stress response stage is the neuroendocrine (fight or flight) axis, which causes intermediate stress effects (Everly & Lating 2013). First, the body engages in a fight or flight response in the presence of a perceived threat, and the primary organ involved in this is process is the adrenal medulla (Everly & Lating, 2013). Next, at the time of this publication, researchers had identified that the dorsomedial amygdlar complex as the utmost point for which the…

mainly cultivated in about 3.92 Mha, accounting for more than 80% of the global pigeonpea production. In the states of Maharashtra, Karnataka and Andhra Pradesh, which account for >50% of the total pigeonpea area. Millions of people in the semi-arid tropics (SAT) are living below poverty line and their livelihood…

the melting of Arctic and Antarctic ice, and permafrost, leading to rising sea levels. Climate change impacts on the animal kingdom. Many species become extinct, others are changing the traditional habitat. The risk of relocation inhabitants of the tropics to temperate latitudes is that the animals are carriers of tropical diseases such as malaria. In addition, warming may increase the incidence of intestinal diseases, asthma, allergies and respiratory…

compounds. Legumes play an important role in the traditional diets of the world population and are a valuable material for the food and animal feed industries (Schuszter-Gajzago, 2004). Pigeon pea is a perennial plant widely grown in the semi-arid tropics of Asia, Africa, and the Caribbean. Pigeon pea, besides its main use as dhal, fresh green seeds is used as a vegetable (Nene and Sheila, 1990). India ranks first in the production of pigeon pea globally and it is second most widely grown…
