Abstract:

The Trinidad Piping Guan, Pipile pipile synonym Aburria pipile (Jaquin, 1784) is the only endemic Cracid on the island of Trinidad. The species is currently listed as Critically Endangered and is considered to be in ‘on-going decline’ by the IUCN, BirdLife International and Cracid Specialist Group. This study aims to examine aspects of genetic variation and the evolution of the mitochondrial genome in the Trinidad Piping Guan utilising, for the first time, samples collected from individuals in the wild and reference specimens of the genus Pipile sourced from museum collections.

Abstract:

Classified as critically endangered since 1994, the Trinidad Piping guan (Pipile pipile) is an endemic species estimated to number less than 200 individuals. Known to locals of Trinidad as the ‘Pawi’ this bird has been the subject of substantial hunting pressures and much of the species habitat has been destroyed through deforestation. Although officially protected since 1958, occasional recreational hunting of this elusive species still occurs. Due to difficulties locating and capturing the species, no genetic research has previously been performed using samples obtained from Trinidad. All pr

Abstract:

Pressure transients are caused by a change in the volumetric flow in a pipeline system, and can have severe consequences for rapid changes of the volumetric flow. A sudden closure of a valve is a common source of a pressure transient, and the pressure increase in front of the valve depends on the flow rate and the wave propagation velocity in the fluid and pipe. A gas-liquid mixture can have a very low wave propagation velocity, even for small air contents, and is effective in terms of damping due to the compressibility effects of the gas bubbles. With these alterations of the fluid properties

Breeding dispersal can be a way for an individual to improve its fitness. Own reproductive success has been shown to be a cue to dispersal among many bird species. Natural selection should favor dispersal to higher-quality territories and a larger territory is predicted to improve fitness. Data from male rock pipits, Anthus petrosus littoralis, on the Swedish west coast indicated, as predicted, that dispersal follows an unsuccessful breeding year. However, no fitness improvement was detected after dispersal, leading to the conclusion that dispersing in itself does not lead to better fitness. I

Piping of the submarine is one major part under diving pressure. The best way to assure these prerequisites, is to inspect piping frequently and using destructive and non destructive methods to

Abstract:

The behaviour of piping elbows under bending and internal pressure is more complicated than expected. The main problem is that the coupling of bending and internal pressure is non-linear; stress and displacement cannot be added according to the principle of superposition. In addition, internal pressure tends to act against the effect caused by the bending moment. If bending moment ovalises the elbow crosssection, with internal pressure acting against this deformation, then the deformed cross-section tries to deform back to the original circular shape. It is then introduced the term ''pressure

Internal erosion often occurs when seepage flow is concentrated into a small, unprotected opening. One such example is where sandy soil is eroded through a defect in an overlying clay layer, resulting in a sand boil in the process. The erosion initiates through the heave and backward piping mechanisms and continues beneath the clay layer through the piping process, forming a pipe that progresses toward the source of the seepage. The initiation of erosion at the seepage flow concentration is a complex mechanism involving a number of hydraulic and soil mechanics principles, including: flow conce

I studied the piping plover on Assateague Island during the 1986 and 1987 breeding seasons. In 1987, I estimated the population to be 69 pairs. During both years, plovers nested on only a few portions of the island. I think that this pattern of nesting was determined by the distribution of three types of foraging habitats: bayside mud and sand flats, saltwater pools formed by storm tides, and a drawn down waterfowl impoundment. Reproductive rates were lower than two recent estimates of the level necessary to maintain a stable population. The primary problem was poor nest success and the leadin
