Universal antenatal haemoglobinopathy screening in this hospital has identified several women with increased haemoglobin A(2) values, but without hypochromic microcytic red cell indices. This report describes two cases where there is evidence that the raised haemoglobin A(2) value is not caused by heterozygous beta thalassaemia, but rather results from these patients being human immunodeficienc...

Droughts can influence forest composition directly by limiting water or indirectly by intensifying other stressors that affect establishment, growth, and mortality. Using community assemblages of eastern US tree species and drought tolerance characteristics assessed from literature, we examine recent drought conditions in relation to the spatial distribution of species and their tolerance to dr...

The fraction of photosynthetically active radiation (FPAR) absorbed by vegetation – a key parameter in crop biomass and yields as well as net primary productivity models – is critical to guiding crop management activities. However, accurate and reliable estimation of FPAR is often hindered by a paucity of good field-based spectral data, especially for corn crops. Here, we investigate the relati...

BACKGROUND Trauma resuscitations require a high level of team performance. This study evaluated the impact of a comprehensive effort to improve trauma care through multidisciplinary education and the use of simulation training to reinforce training and evaluate performance. METHODS For a 1-year period, expanded trauma education including monthly trauma simulation sessions using high-fidelity ...

INTRODUCTION Traumas represent the cause of 10 % of deaths in the entire world. The successful development of trauma systems, including the use of trauma registries, played a significant part in lowering the mortality and the disabilities due to injuries resulted from trauma. METHOD Review of the literature using computerized database of National Library of Medicine and the International Inst...

The translation vectors of the convenient unit cell, e.g. the cube edges of the fcc structure (which is not primitive) are used for the coordinate axes. The plane shown intercepts at 3, 2, 2 on the axes. As, by definition, these three points are not co-linear, therefore they can adequately define the plane. As we shall see later, the reciprocal of these numbers are more useful. First, reciproca...

Severe hyperglycemia can result in falsely high results for mean cell (erythrocyte) volume (MCV), which will also cause false results for erythrocyte indices calculated on the basis of MCV. Falsely high MCV results were obtained with the Technicon H1 and H2 analyzers and (to a lesser extent) with the Coulter T660. The H analyzers were more susceptible to this interference than was the Coulter T...

Globally, mediterranean-climate ecosystem vegetation has converged on an evergreen, sclerophyllous and shrubby growth form. The particular aspects of mediterranean-climate regions that contribute to this convergence include summer droughts and relatively nutrient-poor soils. We hypothesised that winter-precipitation implies stressful summer droughts and leaches soils due to greater water availa...
