Is intra-plate volcanism dominated by deep or shallow processes?

Abstract
Intra-plate ‘hotspots’ have for a long time been attributed to cylindrical plumes made of hot, buoyant mantle that rises from great depths as deep as the core-mantle boundary. However, there have been a lot of speculations and controversies surrounding the arguments on the true source of these volcanic ‘hot spots’ with numerous scientists siding to defend the shallow volcanicity process as a more tangible explanation. Theories and models of deep volcanicity processes nevertheless dominate the scientific field as the mantle plume-derived sources for hotspot tracks that occur along the oceanic lithosphere are a more straightforward standpoint of mantle Continue reading...

The Anglerfish, also known by its Latin or scientific name, Lophius piscatorius, is one of the more unique marine animals, both in anatomy and predatory habits. With this carnivorous predatory nature, an ugly countenance and extremely clever bioluminescent rod and bait anatomy designed for luring and catching various types of prey, it manages to avoid much work in hunting or capture of prey; it essentially is designed to bring prey right to its mouth, earning it the nickname of the fish that fishes (Murphy 4). Extreme sexual dimorphism and reproductive characteristics dependent upon parasitic relationships between male and female Continue reading...

IS INTRA-PLATE VOLCANISM DOMINATED BY DEEP OR SHALLOW PROCESSES?
Introduction
Controversial Topic
There have been a lot of controversies surrounding the question on the true source of volcanicity activities. Numerous scientists have sided to defend the shallow volcanicity process arguing that anomalous magmatism processes are the resultant effects of the melting of fertile bodies due to temperature variations in the shallow mantle rather than the deep mantle thermal plumes. These scientists have attributed volcanism to result from shallow upper mantle processes like edge-driven convection between the thick and thin lithosphere at the boundaries, lithospheric thinning, lithospheric extension and small-scale Continue reading...

"It's a Shame to Put Such Wonderful Thoughts in Such Poor Language": A Chemist's Perspective on Writing in the Discipline

Roland P. Stout, University of North Carolina Pembroke
Abstract: Starting from the premise that good writing requires sound thinking, this paper presents a workable process for developing and using writing assignments as thinking and learning tools within a historical and philosophical context. Though presented from the perspective of a chemist, this process is actually general in nature and links writing assignments with specific learning objectives and evaluation methods. Writing assignment examples, used for a variety of purposes, draw from freshman through graduate courses in chemistry.

The Deep-water Horizon oil spill was an oil disaster that occurred in the Gulf of Mexico from 20th April 2010. This project was owned by BP Oil Company and was operated by Transocean Company. The explosion claimed eleven out of the one hundred and twenty-six staff who were stationed at the rig. The oil spill was considered as the largest marine oil spill in the history of the petroleum industry. Although the U.S government tried to contain the flow, there is still evidence of the continued oil leak in areas such as in the beaches of Louisiana, the Tampa Continue reading...

Introduction:

The Persian gulf is part of the Arabian sea situated in between Iran and the Arabian peninsula. It is around 90,000 sq miles that links to the Gulf of Oman extending around 600 miles from the delta of Shatt al Arab to the Hormuz Strait. It is popularly known as the Arabian Gulf. Basically, the Persian Gulf contains many islands and the waters are relatively shallow. The Gulf is rich with oil, producing approximately 28% of the global oil supply and exporting more than 18 million bbl/d. The countries Iran, Bahrain, Kuwait, Saudi Arabia, Qatar, Iraq, and United Continue reading...

On Darwin Island, the total number of finches is about 30.
They have shallow beaks suitable for cracking soft seeds.
Half of them have lost their lives possibly because the type of seeds does not suite their beaks.
Very few finches can survive on Darwin Continue reading...

Among the most abundant sources of light on Earth is life itself.
It’s 10 p.m., and I’m standing in the darkroom of the Western Flyer, a research vessel belonging to the Monterey Bay Aquarium Research Institute. The room is tiny, and several of us are crammed inside. The light is off, the air is warm and stuffy, and—as we’re at sea, 50 miles off the coast of California—the floor keeps rocking. I feel sick. But I don’t care. On a table, in a small dish, is a newly captured Continue reading...

Abstract

The different cells of the higher animals create specialized organs, tissues, and systems that have particular functions. For example, the tissue organizations that constitute the respiratory system promote breathing and, hence, allow the exchange of gases. The cardiovascular arrangement employs the blood to transport the gases, as well as other substances in the body. Additionally, the respiratory and cardiovascular systems have a close integration, such that a response to a body change in one system is manifested in the second system. The present study, therefore, investigated the cardiovascular physiology, as well as the integration of the respiratory and the Continue reading...

Perhaps one of the most profoundly written novels in modern American history, is the literary acclaimed work of Harper Lee’s “To Kill a Mockingbird.” Set in the context of a highly racialized and segregated Deep South, the work is based upon the recollections of Lee during the 1930s of her childhood. One scholarly journal pertaining to the improvement and encouragement of young readers, observes that children and youth enjoy reading about the lives and real-world experiences of authors and other famous figures. In it Barbara Ward and Terrell Young advocate that adolescent readers read Harper Lee’s biography – Continue reading...
