We tried to develop a real time face detection and recognition system which uses an “appearance-based” approach. For detection purpose we used Viola Jones algorithm. To recognize face we worked with Eigen Faces which is a PCA based algorithm. In a real time to recognize a face we need a data training set. For data training set we took five images of each(More)
AIM To develop and evaluate a multiplex PCR (mPCR) assay for simultaneous detection of 10 bacterial species causing bovine mastitis namely, Staphylococcus aureus, Staphylococcus chromogenes, Staphylococcus epidermidis, Staphylococcus sciuri, Staphylococcus haemolyticus, Staphylococcus simulans, Streptococcus agalactiae, Streptococcus dysgalactiae,(More)
Flavobacterium psychrophilum is the causative agent of coldwater disease, which is responsible for serious losses in fish aquaculture in several parts of the world. No commercial vaccines are currently available for the prevention of coldwater disease. The present study sought to assess the efficacy of a F. psychrophilum vaccine based on the antigenic outer(More)
In this study, 191 culture isolates were recovered from suspected samples of animals and humans in Ellinghausen McCullough Johnson and Harris (EMJH) medium and assessed for its morphological features by dark field microscopy. Extracted DNA from individual culture was subjected to different PCR assays for identification and characterization of leptospira.(More)
To develop an animal model of the haemolytic-uraemic syndrome during shigellosis, rabbits were injected with lipopolysaccharides (LPS) extracted by the hot phenol-water method from Shigella dysenteriae I and from S. flexneri. Two intravenous injections of LPS spaced by 24 h elicited renal cortical necrosis in a generalized Shwartzman reaction characterized(More)
AIM To evaluate the virulence determinants and genetic diversity of Staphylococcus aureus from bovine subclinical mastitis milk. METHODS AND RESULTS PCR detection of virulence genes was performed for 173 Staph. aureus from bovine subclinical mastitis milk. Further, genetic diversity was analysed by agr and spa typing followed by pulsed field gel(More)
Arsenic groundwater contamination in Bangladesh warrants immediate remediation. This randomised controlled intervention trial was conducted to determine the effectiveness of two possible interventions: dug wells and three-pitcher filters. A total of 640 individuals participated with 218 randomised to the dug well group, 216 to the three-pitcher group and(More)
We describe methods for studying the binding of Al by protein in serum: ultrafiltration, gel filtration, and immuno-affinity chromatography. For ultrafiltration we used an Amicon YM10 cellophane membrane with a nominal cutoff of 10 000 Da to separate ultrafiltrable and non-ultrafiltrable Al. For gel filtration we used Sephacryl S-300, and for(More)
In this work, we initiate the investigation of optimization opportunities in collaborative crowdsourcing. Many popular applications, such as collaborative document editing, sentence translation, or citizen science resort to this special form of human-based computing, where, crowd workers with appropriate skills and expertise are required to form groups to(More)
Traditional canola (Brassica napus L.; AACC, 2n = 38) cultivars yield seed oil with a relatively high proportion of α-linolenic acid (ALA; C18:3cisΔ9,12,15), which is desirable from a health perspective. Unfortunately, due to the instability of this fatty acid, elevated levels also result in oils that exhibit a short shelf life and problems associated with(More)
