Upper Awash Agro Industry Enterprises (UAAIE) is one of the major state farms in Ethiopia with known large-scale pesticide use. Although organochlorine pesticides (OCPs) have been applied for about three decades, no studies have been carried out on levels of residue in the region. In this work a fast selective pressurised liquid extraction (SPLE) methodology has successfully been applied for scree

The social networks of individuals with severe mental illness admitted to long-term in-patient settings and living in two types of supported housing, small congregate community residences and independent living with support, were compared. The Interview Schedule for Social Interaction (ISSI) was used. The results showed no substantial differences in social networks between the two types of support

Temperature not only has direct effects on microbial activity, but can also affect activity indirectly by changing the temperature dependency of the community. This would result in communities performing better over time in response to increased temperatures. We have for the first time studied the effect of soil temperature (5-50 degrees C) on the community adaptation of both bacterial (leucine in

In a laboratory experiment, northern pike Esox lucius gastric evacuation rates did not differ between equal-mass rations of small and large prey. In a comparison between intermediate and large prey, the pike were unable to fit two intermediate prey completely into the stomach at the same time, resulting in two consecutive evacuations, and changes in patterns of gastric evacuation. Thus. total gast

High-repetition-rate laser-induced fluorescence measurements of fuel and OH concentrations in internal combustion engines are demonstrated. Series of as many as eight fluorescence images, with a temporal resolution ranging from 10 mus to 1 ms, are acquired within one engine cycle. A multiple-laser system in combination with a multiple-CCD camera is used for cycle-resolved imaging in spark-ignition

Background: The clinical management of patients with coronary artery disease (CAD) often involves a complex assessment of the extent and severity of changes in left ventricular (LV) myocardial perfusion, function and viability. We aimed to explore the feasibility of integrative quantitative representation of LV perfusion, function and viability in adjacent polar plots. In order to assess the clini

The frequency of micronuclei (MN) in peripheral blood lymphocytes (PBL) is extensively used as a biomarker of chromosomal damage and genome stability in human populations. Much theoretical evidence has been accumulated supporting the causal role of MN induction in cancer development, although prospective cohort studies are needed to validate MN as a cancer risk biomarker. A total of 6718 subjects

DSC studies were carried out in the heating-cooling cycles for non-irradiated and irradiated with gamma-rays ((CO)-C-60) using 30 kGy dose wheat flour. The differences between gelatinisation and reversible transition of amylose-lipid complexes occurring in suspensions of non-irradiated and the irradiated flour (characterized by a dry matter to water ratio of 1: 1 and 1:3) depend on the conditions

Heat generation due to plastic deformation of metals and steel is studied. Whereas in many investigations it is assumed that the fraction eta of the plastic work transformed into heat is constant throughout the deformation process, the fraction eta is here derived from thermodynamic considerations in a large-strain setting. It is shown that for elasto-plasticity the fraction eta follows as a resul

The effects of liming on ectomycorrhizal mycelial colonization and carbon allocation were assessed using Pinus silvestris plants grown in association with an ectomycorrhizal fungus. Plants were placed in perspex growth chambers divided by a central partition so that soils of different pH could be used on either side of the chambers. Differences between the growth form and growth rates of the fungi

Introduction: Activation recovery time (ART), defined as the time from the earliest ventricular activation time to the end of T wave on unipolar electrograms, has been used as an index of myocardial repolarization time. However, it is unknown whether the ART can be used to estimate the global sequence and dispersion of ventricular repolarization as determined by the monophasic action potential (MA

BACKGROUND. Endometrial carcinomas seem to carry a different prognosis depending on the presence or absence of concomitant complex atypical hyperplasia (hyperplasia). The molecular genetic profile of these two pathogenetic types, based on the genes reportedly mutated in these cancers, remains to be defined. Although microsatellite inability is reported in approximately 25% of endometrial carcinoma
