Hepatitis B and C virus (HBV/HCV) infections are serious global health problems. Shaving by barbers has been identified as the key risk factor for spread of HBV. We conducted a cross-sectional survey of barbers in Hyderabad city, Pakistan in 2007 to establish their knowledge and attitudes to the risk of HBV and HCV transmission and their working patterns. Observations showed that 96.2% washed r...

Three hundred and nineteen patients who had chondromalacia patellae and persistent patellofemoral pain after six months of conservative management underwent arthroscopy and arthroscopic surgery. The results in four aetiological groups were reviewed at one year and five years after operation. Morbidity was minimal. Lavage produced early remission in all groups. Shaving offered a particular advan...

This paper presents linear programming (LP) formulations for short-term energy time-shift operational scheduling with energy storage systems (ESSs) in power grids. In particular, it is shown that the conventional nonlinear formulations for electric bill minimization, peak shaving, and load leveling can be formulated in the LP framework. New variables for the peak and off-peak values are introdu...

To integrate more renewable energy into the power grid, large-scale thermal plants have to extend their operating ranges and participating in deep peak shaving. In order improve economy of shaving, determine performance a system under different conditions, method modeling for prediction shaving is proposed. algorithm design model, three-layer iterative cycle logic constructed, coupling relation...

A key application of clustering data obtained from sources such as microarray, protein mass spectroscopy, and phylogenetic profile is the detection of functionally related genes. Typically, only a small number of functionally related genes cluster into one or more groups, and the rest need to be pruned. For such situations, we present Automated Hierarchical Density Shaving (Auto-HDS), a framewo...

We report a complication that occurred when using a frova intubating introducer to assist placement of a Mallinckrodt double lumen tube (DLT) in a patient undergoing oesphagectomy. The non compatibility of this commonly used airway device with the DLT resulted in plastic shavings from the introducer contaminating the patients bronchial tree. All fragments of plastic were retrieved and the patie...

We consider a consumer of a resource, such as electricity, who must pay a per unit charge to procure the resource, as well as a peak demand charge. We will present an efficient linear programming formulation for the demand response of such a consumer who could be a price taker, industrial or commercial user of electricity that has some ability to self-generate. We will establish a monotonicity ...

The analysis of high-throughput data sets, such as microarray data, often requires that individual variables (genes, for example) be grouped into small clusters such that all the variables in any given cluster have highly correlated values across all samples. Gene shaving is an established method for generating such clusters, but is overly sensitive to the input data: changing one sample out of...

A study in Egypt determined the prevalence of hepatitis B and C virus infections among barbers (n = 308) and their clients (n = 308) in Gharbia governorate, and assessed knowledge, attitude and practices during hair-cutting and shaving. HBsAg was detected among 4.2% of barbers and 3.9% of clients (more urban than rural). Anti-HC antibodies were detected in 12.3% of barbers and 12.7% of clients....
