A method for simultaneously estimating the admixture proportions of a hybrid population and Wright's fixation index, FST, for that hybrid is presented. It is shown that the variance of admixture estimates can be partitioned into two components: (1) due to sample size, and (2) due to evolutionary variance (i.e., genetic drift). A chi-square test used to detect heterogeneity of admixture estimate...

abstract in this research sand drifts potential using sand rose graph software and fryberger velocity classes’ method investigated. thus wind data between 1985 and 2005 from meteorological stations of jask and kerman were analyzed to examine sand drift potential. sand drift potential amount of kerman station was 412.6 using sand rose graph and 401.09 using fryberger,s method. sand drift potenti...

In this paper statistical and time series models are used for determining the random drift of a dynamically Tuned Gyroscope (DTG). This drift is compensated with optimal predictive transfer function. Also nonlinear neural-network and fuzzy-neural models are investigated for prediction and compensation of the random drift. Finally the different models are compared together and their advantages a...

BACKGROUND Afro-Caribbean ethnic minorities are at high risk of stroke and the sequelae of hypertension. OBJECTIVE To investigate cardiovascular risk factors and Dundee risk rank in Afro-Caribbeans attending one inner city general practice and to find which methods of health promotion patients preferred. METHODS We assessed cardiovascular risk including systolic and diastolic blood pressure...

Objective To understand the ethnic differences in coronary heart disease risk among inpatients with diabetes following acute coronary syndrome. Design Single-centre retrospective cohort-analysis of patients with type II diabetes over a six-year period receiving standard care. Setting Birmingham, UK. Participants One thousand and one hundred and five patients with type II diabetes from a m...

Semi-active base isolation system has been proposed mainly to mitigate the base drift of isolated structures while in most cases, its application causes the maximum acceleration of superstructure to be increased. In this paper, designing optimal semi-active base isolation system composed of linear base isolation system with low damping and magneto-rheological (MR) damper has been studied for co...

The incident angle of ground motion is one of the sources of uncertainty in the seismic response of buildings. Moreover, understanding the structural response to the impose ground motion may cause significant changes in the maximum response of buildings. In order to investigate the effect of the spatial distribution of orthogonal components of earthquake strong motion on the structural response...

BACKGROUND The increase in disease burden has continued to weigh upon health systems in Africa. The role of the laboratory has become increasingly critical in the improvement of health for diagnosis, management and treatment of diseases. In response, the World Health Organization Regional Office for Africa (WHO AFRO) and its partners created the WHO AFRO Stepwise Laboratory (Quality) Improvemen...

ABSTRACT Coevolution of the angular leaf spot pathogen, Phaeoisariopsis griseola, with its common bean host has been demonstrated, and P. griseola isolates have been divided into Andean and Mesoamerican groups that correspond to defined bean gene pools. Recent characterization of P. griseola isolates from Africa has identified a group of isolates classified as Andean using random amplified poly...

Curvilinear depressions and chains of asymmetrical to circular pits up a few meters deep tens wide have been mapped on the upper continental slope beyond mid-Norwegian shelf. These features are interpreted represent continuum seafloor landforms produced by grounding iceberg keels at successive low tides. The occur along 50 km long stretch in modern water depths between 400 500 m. average distan...
