the relationship between initial population density of rice white tip nematode (aphelenchoides besseyi) and yield was examined on oryzae sativa cv. alikazemi. experiments were conducted in greenhouse, micro-plot and field conditions. seinhorst’s model was used to describe the relationship between nematode population density and crop yield. the parameters of the model, minimum yield (m), constan...

This study was conducted to investigate the effect of replacing barley with different levels of ground date seeds (GDS) in the diet (0, 15, 3o and 45%) on performance of local growing male goats. Sixteen local male kids (average live weight 16.1±1.41 kg) were allocated randomly to four treatments (4 animal/treatment). The trial consisted of a 14 day acclimatization period followed by a 60-day m...

Background To understand the full impact of stunting in childhood it is important to consider the long-run effects of undernutrition on the outcomes of adults who were affected in early life. Focusing on the costs of stunting provides a means of evaluating the economic case for investing in childhood nutrition. Methods We review the literature on the association between stunting and undernutr...

The effect of feed supplemented with L-camitine at four levels of 0, 300, 600 and 900mg kg-1 on growth performance and body composition of beluga, H. huso, juveniles was evaluate din two separate trials. In the first trial, 180 juveniles (525±9gw) were fed with the test diet for a period of 71 days, and the trial extended to another 126 days in the second phase by randomly selecting 120 juvenil...

In a number of important clinical issues such as evaluation of the efficacy or effectiveness of therapeutic or preventive interventions as well as for comparing the harms of interventions, randomized controlled trials (RCTs) provide the highest levels of evidence, either directly or indirectly. It is obvious that critical appraisal of these studies to assess their validity and precision is of p...

there has been too much of a one-way flow drift down a river of evidence. researchers from rich countries have produced the primary evidence which they proceed to summarise within reviews. these summaries have directed care worldwide. however, things are changing and the river of evidence can flow in the other direction. the care of women with eclampsia has been changed or refined throughout th...
