During the past decade an increasing number of countries have adopted policies that emphasize donation after cardiocirculatory death (DCD) in an attempt to address the widening gap between the demand for transplantable organs and the availability of organs from donation after brain death (DBD) donors. In order to examine how these policy shifts have affected overall deceased organ donor (DD) an...

The use of dry land for shallot cultivation in Indonesia is still not optimal because it considered as that has no good potential crop cultivation. Dry problems include limited availability water, low organic matter and soil nutrients, especially potassium. purpose this experiment was to determine the response vermicompost KNO3 fertilizer growth yield shallots on land. experimental design used ...

In this paper, we generalize the models used by MacKay [1] in his analysis of evolutionary strategies that are based on sexual, rather than asexual, reproduction methods. This analysis can contribute to the understanding of the relative power of genetic algorithms over search methods based upon stochastic hill-climbing, e.g. [2], [3].

introduction: spatial variation of soil properties is significantly influenced by numerous environmental factors such as landscape features, including position, topography, slope gradient and aspect, parent material, climate and vegetation. soil properties vary spatially in south- and north-facing hill slopes. this factor (different slope aspects) can affect the distribution of soil organic mat...

conclusions glenohumeral joint reduction with reconstruction of the humeral head seems to be possible even in a neglected locked posterior shoulder fracture-dislocation. if the depressed osteochondral fragment is still spheric, signs of the avascular necrosis are absent on ct, and mal:union: of the fragment has occurred, it is quite possible to reconstruct the head. although results of the case...

A rider in a roller coaster lets go of a particle such as a small marble. How far does the marble travel horizontally from the point of release before hitting the ground, assuming the speed of the roller coaster is determined by conservation of mechanical energy starting from the highest hill up which it was pulled? Where should the marble be released along the track if one wishes to maximize t...

We develop and analyze a single-degree-of-freedom model for multilegged locomotion in the horizontal (ground) plane. The model is a hybrid dynamical system incorporating rudimentary motoneuronal activation and agonist-antagonist Hill-type muscle pairs that drive a point mass body along a line. Composition of the smooth stance phase dynamics with various discrete lift-off and touch-down protocol...
