Crop rows oriented at a right angle to sunlight direction (i.e., east–west within the winter cropping system in Western Australia) may suppress weed growth through greater shading of weeds in the interrow spaces. This was investigated in the districts of Merredin and Beverley, Western Australian (latitudes of 31u and 32uS) from 2002 to 2005 (four trials). Winter grain crops (wheat, barley, cano...

BACKGROUND AND AIM To identify the geographic distribution of hepatitis C virus (HCV) genotypes and HCV RNA viral load in a large number of HCV-infected carriers in Mexico. METHODS Patients with chronic hepatitis C (n = 8,802) were studied to identify HCV genotype using an immune line probe assay in samples shown previously to be positive for viral RNA by an RT-PCR test. Baseline HCV RNA was ...

BACKGROUND Child undernutrition showed geographical inequalities due to variations in contextual determinants from area to area which indicates that location is an important factor in child undernutrition. However, there are limited studies on spatial epidemiology of child undernutrition in Ethiopia. This study was aimed to identify the SaTScan spatial clusters of child undernutrition in Ethiop...

garlic (allium sativum l.) as one of the most valuable industrial and pharmaceutical plants has been studied from many aspects because of its importance. but there is not any sufficient and reliable information about its distribution and classification. so its types are categorized according to traditional, local or geographical names or some visual traits. the most important reason is the ster...

Laterality is a well described phenomenon in domestic dogs. It was shown that dogs, under calm Earth's magnetic field conditions, when marking their home ranges, tend to head about north- or southwards and display thus magnetic alignment. The question arises whether magnetic alignment might be affected or even compromised by laterality and vice versa. We tested the preference of dogs to choose ...

Barn Orientation The first freestall barn design criteria to consider should be the orientation of the structure. Barns with a north-south orientation are exposed to greater solar radiation than barns with an east-west orientation. Sunlight enters north-south oriented barns directly in the morning and afternoon. While afternoon sun is the most detrimental, morning sun also can affect cow behavi...
