Simultaneous risk-limiting audits of a collection of contests have a known minimum chance of leading to a full hand count if any outcomes are wrong. They are generally performed in stages. Each stage involves drawing a sample of ballots, comparing a hand count of the votes on those ballots with the original count, and assessing the evidence that the original outcomes agree with the outcomes tha...

The estimation of single nucleotide polymorphism (SNP) allele frequency in pooled DNA samples has been proposed as a cost-effective approach to whole genome association studies. However, the key issue is the allele frequency window in which a genotyping method operates and provides a statistically reliable answer. We assessed the homogeneous mass extend assay and estimated the variance associat...

Some case-control genome-wide association studies (CCGWASs) select promising single nucleotide polymorphisms (SNPs) by ranking corresponding p-values, rather than by applying the same p-value threshold to each SNP. For such a study, we define the detection probability (DP) for a specific disease-associated SNP as the probability that the SNP will be "T-selected," namely have one of the top T la...

Objectives : To study the cord blood nucleated RBC count (NRBC) in asphyxiated and nonasphyxiated fetuses at birth and to find out the correlation between NRBC count, fetal acidosis and the clinical markers of asphyxia. Methods : This is a prospective comparative study conducted between 2002 and 2004. Parturient women who were in labor between 37 and 42 weeks of gestation were selected after sa...

Leukocyte differential count is one of the most frequently ordered clinical tests in hospitals. This paper reports a point-of-care test for the leukocyte count by using a microflow cytometer and a fluorescent dye assay. The dye assay relied on fluorescent detection alone to count leukocytes in blood and to identify leukocyte subtypes. By combining the fluorescent assay with a sheathless microfl...

The present study was undertaken with the aim of investigating the physical parameters (e.g. organoleptic and specific gravity of raw milk) and also to study the microbiological quality of raw milk (total viable count, Coliform count and Staphylococcal count) from different villages and Bangladesh Agricultural University (BAU) Dairy Farm of Mymensingh District of Bangladesh, during the period f...

Determining the rate of rotation molecules from their fluorescence anisotropy decay curves is a powerful method for studying molecular systems in biological applications. The single photon count detection used this have nonlinear dependence counting on intensity flux (photon loss effect), which can lead to number artifacts. Using metal complexes phthalocyanines as test sample, we shown that suc...

Objective: There exists a variety of methodologies for the quantitation of effective renal plasma flow (ERPF) with 99"'Tc-MAG3, from very accurate in vitro techniques to less accurate, yet reliable and easy gamma camera methods. This study compares a new technique that uses a single blood sample but does not require the preparation of a standard, with the in vitro single sample ERPF determinati...

Microscale separation tools such as capillary chromatography and capillary electrophoresis (CE) allow the study of metabolism in individual cells. In this work, we demonstrate that single-cell analysis describes metabolism more accurately than analysis of cellular extracts. We incubated HT29 cells (human colon adenocarcinoma) with a fluorescently labeled metabolic probe. This disaccharide, LacN...
