Abstract: Background: GDM is a condition where there is an onset of carbohydrate intolerance during pregnancy. In this condition many changes will take place in carbohydrate metabolism and other metabolic pathways especially in lipid metabolism. These metabolic changes associated with insulin resistance and dyslipidemia. We have aim to study the association between dyslipidemia and glycated haemoglobin. Materials and Methods: The study was conducted in 80 pregnant women of rural population of Puducherry in two groups. Group 1 includes 40 newly diagnosed GDM patients by DIPSI and Group II with 40 normal pregnant women, age group were between 20 to 40 years. Fasting blood glucose, 2-hour post glucose and lipid profile were estimated by auto analyzer. HbA1c was analysis by HPLC method. For comparisons of means student t-test was used to determine the significance between GDM and controls. Results: There was statistically significant difference in lipid profiles (P = 0.05), HDL (P = 0.04), VLDL (P = 0.00), LDL (P = 0.04) HDL (P = 0.04) in GDM groups. HbA1c (P = 0.02) levels were statistically significant with GDM pregnant women. There was no statically significant difference between FG (P

Abstract: Bilirubin has both antioxidant activity and cardioprotective potential. Decreased levels are associated with predicting CAD. Recent studies showed that bilirubin has inverse correlation with glycemic status. So in this we evaluated the role of Hepatobiliary function as a marker of predictor CAD in patient with T2DM. Total 100 subjects included 50 T2DM patients with CAD and 50 T2DM without CAD. All the subject venous blood was collected after overnight fasting for biochemical analysis. After the statistical analysis, the results showed significant difference between two groups as follows total bilirubin (0.32 ± 0.15; 0.90 ± 032; p = 0.000), direct bilirubin, indirect bilirubibn, Total Protein, Albumin, ALT, AST, HbA1c. Our finding implies that decreased serum bilirubin increases the risk of CAD in patients with T2DM and it shows inverse correlation between HbA1c and bilirubin.
Effect of atrazine (Herbicide) on blood parameters of common carp Cyprinus carpio (Actinopterygii: Cypriniformes)

African Journal of Environmental Science and Technology , 2009,
Abstract: In the present study an attempt was made to investigate the acute toxicity of atrazine (ATR) a herbicide on an economically important fish, Cyprinus carpio. In which, 24 h median lethal concentration (24 h LC50) of herbicide, atrazine to C. carpio was 18.5 ppm. Due to fish exposure to 24 h LC50 of atrazine for 24 h, red blood cells (RBCs) count (-63.17%), hemoglobin (-27.35%), plasma glucose (-6.78%) and plasma protein (-18.73%) levels were decreased; whereas white blood cells (WBCs) count (+3.73%) was enhanced. The differences in haematological and biochemical values were statistically significant (p < 0.05). However, WBC count was not significantly changed. The alterations of the above parameters could be used as an important tool for the assessment of pathological conditions of fish.
Optical Effects on the Characteristics of a Nanoscale Finfet

PIER B , 2010,
Abstract: The effect of optical radiation on a uniformly doped nanoscale FinFET considering quantum mechanical effects has been theoretically examined and analyzed. The device characteristics are obtained from the self-consistent solution of 3D Poisson-Schr dinger equation using interpolating wavelet method. To our best knowledge this is the first approach for the self-consistent solution to surface potential computations of nanoscale FinFET photodetector using interpolating wavelets. This method provides more accurate results by dynamically adjusting the computational mesh and scales the CPU time linearly with the number of mesh points using polynomial interpolation, hence reducing the numerical cost. A fine mesh can be used in domains where the unknown quantities are varying rapidly and a coarse mesh can be used where the unknowns are varying slowly. The results obtained for dark and illuminated conditions are used to examine the performance of the device for its suitable use as a photodetector.

PIER B , 2011, DOI: 10.2528/PIERB11042505
Abstract: The biosensor design for sensing of biological signals is highly complex for accurate detection. Optimal detection of biological signals is necessary for distinguishing different tissues. This paper proposes a threshold-based detection technique which provides significant improvement in FinFET optical biosensor performance using wavelet coefficients. It uses a simple maximum likelihood (ML) function for detecting the threshold values. In this method, we have considered the different layers of body tissue as a turbid medium. To the best of our knowledge, this method is the first of its kind for classifying different tissues using threshold value of optical signals obtained from the surface potential variations of nanoscale FinFET illuminated by laser source of different wavelengths. By using this method, the point to point variations in tissue composition and structural variations in healthy and diseased tissues could be identified. The results obtained are used to examine the performance of the device for its suitable use as a nanoscale sensor.

Abstract: Textile dyeing industries in Erode and Tirupur district of Tamilnadu (India) discharge effluents ranging between 100 and 200m3/t of production. Dyeing is performed by Jigger or advanced Soft Flow reactor process. Coloring of hosiery fabric takes place in the presence of high concentration of sodium sulphate or sodium chloride (30 – 75 kg/m3) in dye solutions. Wash water and dye bath waste water are the process effluents of dyeing industry which are collected separately and follow the advanced treatment for maximum recycling of recovered waters. Wash water is treated using a sequence of physicochemical and biological unit process, the waste water is passed into ultrafiltration (UF), two stages reverse osmosis (RO) membrane system where the permeate is reused for processes. The rejects about 10 – 12 % of the inlet volume is subject to reverse osmosis for sent to evaporators. Dye bath water after treating, the permeate is used in process for dye bath preparation and the reject of about 20 – 25% is sent to multi effect evaporator / solar evaporation pond (SEP). The final rejects from reverse osmosis system is directed to multi effect evaporator system where condensed waters are recovered. The removal of Total Dissolved Solids (TDS), Chemical Oxygen Demand (COD) and Chloride are in the range of 82 – 97%, 90 – 97% and 78 – 97% respectively. This study was carrier out Common Effluent Treatment Plant (CETP), Perundurai, SIPCOT, Erode district.

S. Ramesh, R. Praveen
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.77091
Abstract: The Intermittently Connected Mobile Networks (ICMN) is a disconnected mobile network where a complete connectivity never exists.More number of moving nodes makes them impenetrable genre which in turn makes the network intermittently connected. Detection of malicious node and routing is onerous due to its genre. In this paper, we put forward a secure routing that aids in detecting and preventing intrusion of malicious nodes. The routing process is made more adorable through Bee Colony Optimization (BCO). The amalgamation of BCO with authentication series leads a novel routing protocol named Privacy Preserving Bee Routing Protocol (PPBRP) which is highly secure. The degree of security is tested with malicious nodes in the network to prove that the proposed PPBRP ensures secure routing.

Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.77092
Abstract: Wireless and mobile networks seem to deliver tremendous uses. In its way, MANET leads to enormous real world applications. Routing allows us to implement many real world applications. Complete affinity in an infrequent network like ICMANET is highly impossible. Disconnected MANET is also known as ICMANET which is also a DTN (Delay Torrent Network) that supports for higher delays. It is laborious process to execute routing in a diffused network process to execute routing in a diffused network. To deliver the data packets towards the destined node to its best, a new strategy in routing called Ant routing protocol in concoction with storage strategy LoDis has been proposed. Despite of routing, security is still an unsolved problem. To evaluate this situation, this paper presents a methodology called agent technology which yields a secure routing. Hostile node in the network is spotted with the help of agent at each node. A cryptographic algorithm Advanced Encryption Standard (AES) is habituated to improve secure communication in wide range Mobility and total number of nodes in the network act as variables in examining the hostile nodes in the network to judge the standard of security. Improved performance along with the security is the point to be highlighted.
