In late 1990, executives, engineers, and financial advisors working for Amoco Corporation and Apache Corporation began serious discussions about the sale to Apache of MW Petroleum Corporation, a wholly-owned subsidiary of Amoco Production Company. Amoco had transferred to MW certain of its own assets that it regarded as non-strategic. MW,s size, location, and operations were all very attractive to Apache, which had grown nearly 30% per year since the mid-1980s

Background Diarrhea is a clinical syndrome of diverse etiology associated with many influencing factors. It is the most frequent childhood disease second only to the respiratory infection. The major cause of death among world's children and the number one killer of children under five in many developing countries

16.1 Water circulates through the hydrologic cycle (水文循环) The Earth's water is constantly circulating, powered by the heat of the sun and the force of gravity. Water evaporated from ocean precipitates(降水) into the ocean: direct route. Water evaporated from ocean is blown by winds until it is over the land and precipitates: (1) evaporates beck into atmosphere, (2). Infiltrate

In this lecture, we will consider how to transfer from one orbit, or trajectory, to another. One of the assumptions that we shall make is that the velocity changes of the spacecraft, due to the propulsive effects, occur instantaneously. Although it obviously takes some time for the spacecraft to accelerate to the velocity of the new orbit, this assumption is reasonable when the burn time of the rocket is much smaller than the period of the orbit. In such cases, the Av required to do the maneuver is simply the difference between the

In the previous lectures we have described particle motion as it would be seen by an observer standing still at a fixed origin. This type of motion is called absolute motion. In many situations of practical interest, we find ourselves forced to describe the motion of bodies while we are simultaneously moving with respect to a more basic reference. There are many examples were such situations occur. The absolute motion of a passenger inside an aircraft is best

More Problems With Culture 1. The culture concept has been used and misused This notion has traveled around the world it can be considered one of Anthropology's great successes b. Culture has also been distorted 1. Assumptions that cultures have clear boundaries

1 Regression Regression is probably the single most important tool at the econometrician's disposal. What is regression analysis? It is concerned with describing and evaluating the relationship between a given variable (usually called the dependent variable) and one or more other

1. INTRO We all suffer in writing, one way or another. We have trouble writing or we get writer's block. But there are ways to go at it that are less painful. a. Divide and conquer the rules of writing. Taking them one at a time will make learning the rules earlier. i. We'll keep nagging you on your writing. Take the time to go over the comments we write on your papers

Industrial Microbiology and Fermentation Technology Industrial Microbiology is the discipline that uses microorganisms, usually grown on a large scale, to produce valuable commercial products or carry out important chemical transformations. Fermentation Technology is the technology to grow cells in large scale with high efficiency, it also includes product recovery processes
