The wood mechanical properties of progeny from twelve open-pollinated parent trees were examined. Six families were from parents which had high wood specific gravity and six were from parents which had low wood specific gravity. Thirty-two-year-old trees, that had been planted at Many, Louisiana, were sampled and juvenile and mature wood test specimens were prepared. Maximum crushing strength, ...

The ability of a certain genotype to express different phenotypes depending on variations in the environment is called phenotypic plasticity. Predator induced defences are among the most studied and wide spread examples of phenotypic plasticity. For example, in freshwaters, predators are constantly shaping communities with their presence and a plethora of defensive adaptations in prey have evol...

"Recommendations for the management of crush victims in mass disasters" aims to assist medics, paramedics and rescue team members who provide care during disasters. Development of the recommendations followed an explicit process of literature review and, also internet and face-to-face discussions. The chapters cover medical and logistic measures, to be taken both at the disaster field and in th...

For patients who have difficulty swallowing, a common solution is to crush tablets or open capsules. What are the consequences of this practice? We reviewed the main evidence available using the standard Prescrire methodology. The clinical consequences for the patient of crushing tablets or opening capsules can be serious: alteration of the drug's absorption can result in sometimes fatal overdo...

All stingrays in the family Myliobatidae are durophagous, consuming bivalves and gastropods, as well as decapod crustaceans. Durophagous rays have rigid jaws, flat teeth that interlock to form pavement-like tooth plates, and large muscles that generate bite forces capable of fracturing stiff biological composites (e.g. mollusk shell). The relative proportion of different prey types in the diet ...

The construction industry is the largest consumer of natural resources which led to depletion of good quality natural sand (Fine aggregates). This situation led us to explore alternative materials and granular slag a waste industrial byproduct is one such material identified for utilization it as replacement of natural sand. This paper highlights upon the feasibility study for the utilization o...

Introduction and Objective. Bleeding is an important complication in liver transections. To determine the safety and efficacy of Debakey forceps for liver parenchymal transection and its ergonomic advantages over clamp crushing method we analysed our data. Methods. We used Debakey crushing technique in 100 liver resections and analysed data for transection time, transfusion rate, morbidity, mor...

Rupture of the diaphragm and herniation of the abdominal viscera into the chest are wellrecognized results of crushing or penetrating injuries. Gordon Bryan's study (1921) of both types of injury is a surgical classic. The second world war rekindled interest in traumatic diaphragmatic hernia, and several important papers dealt with those due to penetrating injury (Edwards, 1943; Mackey and Bing...
