Some of the main objectives of quality assurance practices are to detect and correct the errors that arise during the development of a software product, as well as to guarantee that the final product conforms to the client’s requirements. Quality initiatives suppose an added cost to the software development projects, cost that is totally justified but which, in most of the cases, is the first o...

Surface mining extensively alters the physical, chemical and biological characteristics of the soil, and therefore, the revegetation of mine spoil through natural process takes a very long time and poses a major problem because nutritionally it is a recalcitrant medium for plant growth. We review important studies on the restoration of mine spoils in the tropical dry region of India. Through th...

Acetoin (acetylmethylcarbinol) has been found in minute amounts in normal human urine (1) and in the blood of the cow, pig, sheep, and horse (2, 3). Westerfeld, Stotz, and Berg (4) have reported that in dogs the rate of disappearance of alcohol from the blood was increased by the administration of pyruvate and that of pyruvate by the administration of alcohol. They interpret their results as in...

We summarise some aspects of experiments currently being built or planned, and indulge in wild speculation about possibilities on the more distant horizon. The satellite missions MAP and Planck dominate any view of future measurements of the anisotropy of the Cosmic Microwave Background. We will attempt to look beyond and around those two experiments and see what sorts of physical questions oth...

The presence of Eriophorum angustifolium in mine tailings of pyrite maintains a neutral pH, despite weathering, thus lowering the release of toxic elements into acid mine drainage water. We investigated if the presence of slightly elevated levels of free toxic elements triggers the plant rhizosphere to change the pH towards neutral by increasing organic acid content. Plants were treated with a ...

his article presents a re-engineering case study of the product requirements definition process at Digital Equipment Corporation. Based on cross-functional teams working in direct partnership with customers, the re-engineered process was designed to ensure customer satisfaction and business readiness before a line of code is written, an electronic circuit designed, or a service defined. Several...

THE increasing importance of geriatric medicine in the medical curriculum is shown by the fact that, whereas ten years ago there were no short soft-cover textbooks on the subject, in 1981 second editions of three of these books appeared. The second edition of this book has the same basic format as the first and is a product of the author's wide knowledge and experience of the subject. Revisions...

The Los Alamos National Laboratory (LANL) in partnership w~h Composite Optics Incorporated (COl), is advancing the development of low-cost, light-weight composite technology for use in small satellites. The use of advance composites in space applications is well-developed, but the application of an all-composite satellite bus has never been achieved. In this paper, we investigate the applicatio...

Kecent trends in research in the field of egg quaUty have been toward the study of the initial condition of the egg rather than the changes that occur during holding periods under varying environmental influences. Most investigators have concerned themselves largely with the so-called interior egg-quality characters and more particularly with the albumen portions of the egg. Practically all suc...
