Optimal capacitor placement in smart distribution systems to improve its maximum loadability and energy efficiency
I Ali, MS Thomas, P Kumar
International Journal of Engineering, Science and Technology , 2011,
Abstract: An energy efficient power distribution network can provide cost-effective and collaborative platform for supporting present and future smart distribution system requirements. Energy efficiency in distribution systems is achieved through reconfiguration of distributed generation and optimal capacitor placement. Though several techniques have been reported earlier for optimal capacitor placement, this paper presents an improved technique based on combining Power Loss Index (PLI) and Maximum Loadability Index (MLI). It takes care of critical compensation to maximize loadability and loss reduction. Improved performance results of the new technique have been demonstrated on an IEEE 15 bus distribution system for different load models. It is demonstrated that the load models have significant effect on selecting the capacitor size. The improvement in the loadability limit in constant impedance loads and the reduction in power loss in constant power loads is more than any other load models. The simultaneous improvement in loadability limit and loss reduction enhances energy efficiency in distribution systems by releasing power demand and feeder capacity.
Digital Transducers and Its Application
MR. SIBU THOMAS,MS. NISHI SHAHNAJ HAIDER
International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering , 2013,
Abstract: This paper describes various types of digital transducers. It also tells their principles of operation and describes how they are applicable in fields. These transducers are nowadays very popular as they produces digital signal as output which can be easily read by digital devices, and there is no such requirement of analog to digital conversion for further analysis of measured quantity.

Stance control knee mechanism for lower-limb support in hybrid neuroprosthesis
Curtis S. To, PhD,Rudi Kobetic, MS,Thomas C. Bulea, MS,Musa L. Audu, PhD
Journal of Rehabilitation Research and Development , 2011,
Abstract: A hydraulic stance control knee mechanism (SCKM) was developed to fully support the knee against flexion during stance and allow uninhibited motion during swing for individuals with paraplegia using functional neuromuscular stimulation (FNS) for gait assistance. The SCKM was optimized for maximum locking torque for body-weight support and minimum resistance when allowing for free knee motion. Ipsilateral and contralateral position and force feedback were used to control the SCKM. Through bench and nondisabled testing, the SCKM was shown to be capable of supporting up to 70 N-m, require no more than 13% of the torque achievable with FNS to facilitate free motion, and responsively and repeatedly unlock under an applied flexion knee torque of up to 49 N-m. Preliminary tests of the SCKM with an individual with paraplegia demonstrated that it could support the body and maintain knee extension during stance without the stimulation of the knee extensor muscles. This was achieved without adversely affecting gait, and knee stability was comparable to gait assisted by knee extensor stimulation during stance.
Effect of adding the novel fiber, PGX?, to commonly consumed foods on glycemic response, glycemic index and GRIP: a simple and effective strategy for reducing post prandial blood glucose levels - a randomized, controlled trial

Nutrition Journal , 2010, DOI: 10.1186/1475-2891-9-58
Abstract: Ten healthy subjects (4M, 6F; age 37.3 ± 3.6 y; BMI 23.8 ± 1.3 kg/m2), participated in an acute, randomized controlled trial. The glycemic response to cornflakes, rice, yogurt, and a frozen dinner with and without 5 g of NVP sprinkled onto the food was determined. In addition, 3 granolas with different levels of NVP and 3 control white breads and one white bread and milk were also consumed. All meals contained 50 g of available carbohydrate. Capillary blood samples were taken fasting and at 15, 30, 45, 60, 90 and 120 min after the start of the meal. The glycemic index (GI) and the glycemic reduction index potential (GRIP) were calculated. The blood glucose concentrations at each time and the iAUC values were subjected to repeated-measures analysis of variance (ANOVA) examining for the effect of test meal. After demonstration of significant heterogeneity, differences between individual means was assessed using GLM ANOVA with Tukey test to adjust for multiple comparisons.Addition of NVP reduced blood glucose response irrespective of food or dose (p < 0.01). The GI of cornflakes, cornflakes+NVP, rice, rice+NVP, yogurt, yogurt+NVP, turkey dinner, and turkey dinner+NVP were 83 ± 8, 58 ± 7, 82 ± 8, 45 ± 4, 44 ± 4, 38 ± 3, 55 ± 5 and 41 ± 4, respectively. The GI of the control granola, and granolas with 2.5 and 5 g of NVP were 64 ± 6, 33 ± 5, and 22 ± 3 respectively. GRIP was 6.8 ± 0.9 units per/g of NVP.Sprinkling or incorporation of NVP into a variety of different foods is highly effective in reducing postprandial glycemia and lowering the GI of a food.NCT00935350.Epidemiological evidence suggests that postprandial glucose levels have a stronger relationship with cardiovascular events than fasting glucose in individuals with diabetes [1,2]. Recent attention has therefore focused on dietary strategies which target the reduction of postprandial hyperglycemia both as a treatment and possible prevention of diabetes and cardiovascular disease. Both quantity and quality of ing
Predicting the subcellular localization of viral proteins within a mammalian host cell

Virology Journal , 2006, DOI: 10.1186/1743-422x-3-24
Abstract: Here, we investigate the extent of utilization of human cellular localization mechanisms by viral proteins and we demonstrate that appropriate eukaryotic subcellular localization predictors can be used to predict viral protein localization within the host cell.Such predictions provide a method to rapidly annotate viral proteomes with subcellular localization information. They are likely to have widespread applications both in the study of the functions of viral proteins in the host cell and in the design of antiviral drugs.Viruses use the host synthetic machinery to replicate. They have evolved mechanisms to exploit the host nucleic acid replication and protein translation apparatus and have also developed strategies to evade humoral immune surveillance. Viral proteins require targeting to the appropriate subcellular compartments of the host cell to fulfill their roles. Viral proteins have been shown experimentally to be localized in many different cellular compartments including the nucleus (for example the protein kinase encoded by Epstein-Barr Virus [1]), the nucleolus (such as the rev and tat proteins from human immunodeficiency virus type 1 [2]), the cytosol (for example the superoxide dismutase-like protein from vaccinia virus [3]), the ER/Golgi apparatus (for example, the US2 and US11 cytomegalovirus proteins [4,5]), the plasma membrane and cell surface (cytomegalovirus gp34 glycoprotein [6]), and the mitochondria (M11L protein from the myxoma virus and several others, reviewed in [7,8]). Targeting to the extracellular space is also observed (for example, cowpox growth factor [9] and the myxoma M-T7 protein [10]).Protein subcellular localization prediction has been widely studied (reviewed in [11,12]). Available predictors differ in many aspects including the computational method used, the type and diversity of protein characteristics considered for the prediction, the localization coverage, the target organism(s) and the reliability. Predictors can be groupe

Kathmandu University Medical Journal , 2009, DOI: 10.3126/kumj.v7i3.2739
Abstract: A mandibular first molar with two distal roots is an interesting example of anatomic variation. This paper describes case reports of mandibular first molar with three roots (one mesial and two distal) and four canals (two in mesial and one in each distobuccal and distolingual root). The canals were shaped with protaper rotary files and irrigated with 5.25% sodium hyochlorite, 0.2 %w/v of chlorhexidine gluconate and normal saline as the final irrigant. The canals were then obturated with gutta- percha and AH plus sealer. These case reports show an anatomic variation of internal morphology of the tooth and points out the importance of searching for additional canals.

Abstract: A large collection of serotyped Campylobacter isolates, obtained from human clinical faecal samples, were analysed by comparing the ratio of uncommon to common serotypes by different age groups, using χ2 tests.We have identified that older age groups, as well as having generally lower incidence, are significantly less likely to be infected by the more common serotypes.These results are indicative of acquired immunity, however, further studies are needed to rule out the confounding effects of the variations in exposure pathways experienced by different age groups.Campylobacter is the greatest cause of human bacterial gastroenteritis in the developed world [1], with more than 50,000 cases reported in the UK alone each year [2]. However, due to under-reporting, it is believed that the true number of cases is around eight times this [2], suggesting humans are infected on average at least once during their lifetime. Symptoms of campylobacteriosis include fever, abdominal cramp, and bloody diarrhoea, which can last for approximately seven days after infection, with one in a 1000 cases leading to the more serious neurological disease, Guillain-Barré syndrome [3].Approximately 90% of Campylobacter infections are C. jejuni, while the remainder are predominantly C. coli [4]. A variety of typing techniques have been used to subtype these species, including phenotypic Penner heat stable antigen serotyping, genotypic PFGE, AFLP and MLST, which have demonstrated high variability in the genome.Human seroprevalence studies of C. jejuni specific antigens have shown that IgG, IgM, and IgA antibodies are produced during infection [5,6]. The IgM and IgA antibody levels quickly decrease after infection, however, the IgG antibodies can remain elevated for months or years afterwards [5]. A recent study of seroprevalence in Danish adults looked at IgG antibodies in a sample of 1112 people from Copenhagen [7]. It was found that the percentage of people with C.jejuni-specific IgG antibodies

Abstract: 44 children were assigned to low (1 toy) or high (3 toys) choice groups. Children completed 60 min sessions with access to traditional active toys on one visit and exergame versions of the same active toys on another visit.Choice had a greater effect on increasing girls' (146%) than boys' (23%) activity time and on girls' (230%) than boys' (minus 24%) activity intensity. When provided choice, girls' activity time and intensity were no longer lower than boys' activity time and intensity. The combination of choice and mastery by providing access to 3 exergames produced greater increases in physical activity time (1 toy 22.5 min, 3 toys 41.4 min) than choice alone via access to 3 traditional games (1 toy 13.6 min, 3 toys 19.5 min). Energy expenditure was 83% greater when engaging in traditional games than exergames.Boys and girls differ in their behavioral responses to autonomy supportive environments. By providing girls with greater autonomy they can be motivated to engage in physical activity equal to boys. An environment that provides both autonomy and mastery is most efficacious at increasing physical activity time. Though children play exergames 87% longer than traditional games, the rate of energy expenditure is 83% lower for exergames than traditional indoor versions of the same games.Engaging in adequate physical activity is considered an essential component for the maintenance of weight loss and provides many other health benefits for children [1]. However, many children do not engage in adequate physical activity to receive all of its health benefits [2]. Unfortunately, treatment programs based on a number of behavioural change models and applied in a number of settings have not demonstrated efficacy for promoting sustained increases in youth physical activity after cessation of the program [3]. The development of more effective behavioural interventions for increasing youth physical activity depends on improving our understanding of basic factors that influe

Abstract: Several randomized, cross-over trials were performed by a contract research organization using overnight-fasted healthy subjects drawn from a pool of 63 recruited from the general population by newspaper advertisement. Incremental blood-glucose response area-under-the-curve (AUC) elicited by 0, 5, 10, 20, 35 and 50 g CHO portions of WB (WB-CHO) and 3, 5, 10 and 20 g glucose were measured. EGL values of the different doses of glucose and WB and 4 low-CHO foods were determined as: EGL = (F-B)/M, where F is AUC after food and B is y-intercept and M slope of the regression of AUC on grams WB-CHO. The dose-response curves of WB and glucose were used to derive an equation to estimate GL from EGL, and the resulting values compared to GL calculated from the glucose dose-response curve. The accuracy of EGL was assessed by comparing the GL (estimated from EGL) values of the 4 doses of oral-glucose with the amounts actually consumed.Over 0–50 g WB-CHO (n = 10), the dose-response curve was non-linear, but over the range 0–20 g the curve was indistinguishable from linear, with AUC after 0, 5, 10 and 20 g WB-CHO, 10 ± 1, 28 ± 2, 58 ± 5 and 100 ± 6 mmol × min/L, differing significantly from each other (n = 48). The difference between GL values estimated from EGL and those calculated from the dose-response curve was 0 g (95% confidence-interval, ± 0.5 g). The difference between the GL values of the 4 doses of glucose estimated from EGL, and the amounts of glucose actually consumed was 0.2 g (95% confidence-interval, ± 1 g).EGL, a measure of the glycemic impact of low-carbohydrate foods, is valid across the range of 0–20 g CHO, accurate to within 1 g, and at least sensitive enough to detect a glycemic response equivalent to that produced by 3 g oral-glucose in 10 subjects.Decreased postprandial glucose concentrations and diets with a low glycemic load (GL) are associated with reduced risk for cardiovascular disease [1,2], diabetes [3,4] and, perhaps, some forms of cancer [5,6].
