ENPE 573 – Unconventional Gas Exploitation Introduction to Shale Gas Classification‚ Formation‚ & Extraction Abstract The production of conventional gas has been declining over the last few years due to dwindling reserves. To counter-act this decline‚ companies are quickly turning to unconventional gas plays that can offer even greater reserves as shown in figure 1. Unfortunately‚ recovering unconventional gas is a very difficult process that requires advanced stimulation and/or

READING MATERIAL 1. Explain the three hypotheses for the recent changes in the toxicity of venom in different species of rattlesnakes found in the United States. - Interbreeding between snakes with different venom profiles. - Geographic distribution (genes shifted eastward) - Convolution - Old rattlesnakes have high concentration of toxic. 2. What is an “evolutionary arms race”? Describe how this applies to one of the hypotheses suggested to explain toxicity of venom in rattlers

Nonetheless‚ not employing any time-machine contraptions‚ modern archeologists and paleontologists are traveling back in time more than anybody else. They examine the rich iridium layer in Wyoming’s clay deposits and take exploratory tours back to early Cretaceous period. Why? Scientists search for the proof that dinosaurs’ extinction 65 million years ago was caused by a cataclysmic collision of a large extraterrestrial object with the Earth (What Killed The Dinosaurs‚ 2007). The hypothesis is still publicly

Introduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years‚ a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate‚ but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that

Introduction: The Trichoptera‚ or caddisflies‚ are an ecologically diverse order of insects. The adults resemble small moths and are terrestrial‚ while their larvae are aquatic and spin silk (Bongard 2004). It is due to their diverse designs in the secretion of silk threads that they are able to expand their ecological niches. The silk threads of the larvae are used to create shelters‚ nets‚ and cases- adopting an evolutionary system to exploit a wide range of resources (Vaughn 1985). There are about
