in this study caulerpa racemosa has been characterized and used for the removal of cd(ii) and pb (ii) from aqueous solutions. the effect of ph, adsorbent dosage, contact time and temperature on adsorption process was studied in batch experiments. langmuir and freundlich models were applied to describe the biosorption isotherm of the metal ions by c. racemosa biomass. the adsorption data can be ...

For a method for enhancing an image, if it improves the quality enough or it nearly equals to the better method, the primary concern is the speed or the computational complexity and simplicity. Using global contrast stretching, low contrast image can be enhanced with an adjustable manner. Our method is based on a very simple algorithm. Its advantage is that the speed is comparatively fast and t...

Stretching in continuum mechanics is naturally described using the Cauchy–Green strain tensors. These tensors quantify the Lagrangian stretching experienced by a material element, and provide a powerful way to study processes in turbulent fluid flows that involve stretching such as vortex stretching and alignment of anisotropic particles. Analysing data from a simulation of isotropic turbulence...

The purpose of this study was to examine the acute effects of different stretching exercises on the performance of the traditional Wingate test (WT). Fifteen male participants performed five WT; one for familiarization (FT), and the remaining four after no stretching (NS), static stretching (SS), dynamic stretching (DS), and proprioceptive neuromuscular facilitation (PNF). Stretches were target...

The time courses of interleukin (IL)-6 gene expression and protein production were examined in human pulmonary artery endothelial cells (HPAECs) subjected to cyclic stretching. IL-6 protein was increased even in cells without stretching. Fold changes determined by dividing the level of IL-6 protein in stretched cells by that in unstretched cells at the same sampling times indicated that IL-6 pr...

Capsule Endoscopy is a kind of technology that uses tiny disposable capsule which transmits captured images wirelessly of entire gastro-intestinal tract. The motive of proposed method is to enhance the visual quality in the capsule endoscopy images which is critical mainly for diagnosis. In this paper, primarily median filtering is done to reduce the noise. Next, Contrast Limited Adaptive Histo...

Experience suggests the existence of a connection between the contrast of a grayscale image and the gradient magnitude of intensity edges in the neighborhood where the contrast is measured. This observation motivates the development of edge-based contrast enhancement techniques. In this paper, we present a simple and e ective method for image contrast enhancement based on the multiscale edge re...

Miyahara, Y, Naito, H, Ogura, Y, Katamoto, S, and Aoki, J. Effects of proprioceptive neuromuscular facilitation stretching and static stretching on maximal voluntary contraction. J Strength Cond Res 27(1): 195–201, 2013—This study was undertaken to investigate and compare the effects of proprioceptive neuromuscular facilitation (PNF) stretching and static stretching on maximal voluntary contrac...
