A large data set of plant species has been collected in New Zealand from 1990 to 1993 on 10 different sites, where sampling was carried out using quadrates. The 10 sites were categorized into three different area types according to their vegetation growth. Each site was also divided into three subsites according to the animals present/absent. Naturally, biologists are very interested in finding...

The solitary ascidian Herdmania momus is considered native to the Red Sea, and invasive in the Mediterranean. Periodic surveys have revealed high recruitment and growth rates of this species on floating docks in the Gulf of Aqaba, Red Sea, following the annual vertical mixing event. In order to ascertain the length of time taken by H. momus individuals to settle on new artificial substrates, an...

Residual stress states in engineering structures are determined usually by measuring components of stress tensors with depth below the material surface. There are destructive and non-destructive methods to measure strain tensor components and convert them into stress tensor components by a variety of techniques derived from constitutive (material) equations. In this study, four methods for dete...

Background: The ulnar nerve injury induce sever hand malfunction due to intrinsic muscle paralysis. repair in proximal area (high injury) seldom leads function because of long distance return. Therefore, the best techniques restore patient with high is distal transfer minimize regeneration time and distance. Objective: aim this study describe surgical results obtained motor branch anterior inte...

understanding the spatial distribution of weeds would provide good results for the commercial applications of future research programs, development forecast desirable of yield loss and understanding the processes that cause changes in spatial and temporal distribution weeds. in this order an experiment was conducted in 1388 to find the effects of biological interactions, climate and agricultura...

one of the challenges in non-destructive testing schemes using the ultrasound pulse-echo technique is to identify those defects whose sizes are less than or equal to the detection resolution that is dependent on the width of the ultrasound pulse. existing methods also require a reference specimen of the same defective material, which may not be available in some cases. we present a new method f...

The research on entrepreneurship as an economic phenomenon often assumes its desirability as a driver of economic development and growth. However, entrepreneurial talent can be allocated among productive, unproductive and destructive activities. This allocation has important implications in the developing world, particularly for countries hosting conflict or recovering from conflict. The alloca...

We consider the inverse problem of in-line holography, applied to minimally destructive imaging of cold atom clouds. Absorption imaging near resonance provides a simple, but destructive measurement of atom column density. Imaging off resonance greatly reduces heating, and sequential images may be taken. Under the conditions required for off-resonant imaging, the generally intractable inverse pr...
