capillary electrophoresis (ce) with indirect uv detection is an interesting analytical method for the analysis of drugs and pharmaceuticals. good and reproducible capillary quality is needed to develop robust methods and to facilitate method transfer in ce. it is widely accepted that preconditioning procedures are indispensable in capillary electrophoresis in order to achieve reproducibility of...

capture elisa system was developed for diagnosis of visceral leishmaniasis (vl) using a monoclonal antibody raised against an antigen previously detected in the urine of vl patients. urine samples from confirmed vl cases from yemen, nepal, spain, sudan and brazil were tested in the capture elisa in comparison with urine samples from endemic and non-endemic areas along with urine samples from pa...

background : the most frequent use of diatoms in forensic science is the diagnosis of death due to drowning. the basic principle of diatom test in drowning is based on the inference that diatoms are present in medium where drowning took place and the inhaled water enters the alveolar spaces of lungs and penetrates from the alveoli into the blood circulation, thus microscopic unicellular algae c...

in this paper, the capabilities of displacement curvature derived from static response data for finding the location and severity of damage in euler-bernoulli beams are assessed. static response of a beam is obtained using the finite element modeling. in order to reduce the number of measured nodal displacements, the beam deflection is fitted through a polynomial function using a limited number...

microgrid presents an efficient and novel solution for integrating many new energy generating resources with traditional distribution networks. having an appropriate protective scheme is a fundamental challenge in achieving microgrid plans. it is proven that traditional protective plans are not efficient for protecting microgrid, since the network is dynamic and the level of fault current chang...

in this paper, by means of fuzzy approaches, an accurate method is introduced for edging of color photographs. the difference between our method with other similar methods is the use of a morphological operation to think or thick the obtained edges. in this proposed method, a 3×3 window is dragged on the photo. for each block, 12 point sets will be defined, each including two non-overlapping po...

this paper presents a comparison study between the multilayer perceptron (mlp) and radial basis function (rbf) neural networks with supervised learning and back propagation algorithm to track hand gestures. both networks have two output classes which are hand and face. skin is detected by a regional based algorithm in the image, and then networks are applied on video sequences frame by frame in...

in this paper, we present an edge detection method based on wavelet transform and hessian matrix of image at each pixel. many methods which based on wavelet transform, use wavelet transform to approximate the gradient of image and detect edges by searching the modulus maximum of gradient vectors. in our scheme, we use wavelet transform to approximate hessian matrix of image at each pixel, too. ...

the present study was undertaken to screen the soil samples collected in iran for the presence of the bacillus subtilis lipase a gene. the bacterial colonies obtained from the collected soil samples were examined by physical appearance, biochemical tests and  the polymerase chain reaction (pcr). only four colonies were identified as putative b. subtilis strains and all contained the lipase a ge...
