Effect of Chewing Tobacco on Hematological Parameters in Bikaner City Population

1 Sr. Demonstrator, Department of Physiology, S.P. Medical College, Bikaner, Rajasthan Email: dr_dks@yahoo.in, Mobile no.: 07597695195 2 Professor & Head, Dept. of Physiology, S.P. Medical College, Bikaner, Rajasthan Email: dr_binawara@yahoo.com 3,4 Sr. Demonstrator, Department of Physiology, S.P. Medical College, Bikaner, Rajasthan Abstract Background: An increase in the consumption of tobacco has been noticed among high school students, college students, and sportspersons. This study attempts to find out whether ‘chewing tobacco’ causes any adverse effects on the certain hematological parameters. Material & Methods: A cross sectional study has been conducted on the population of Bikaner city (Rajasthan) aged between eighteen years to fifty five years in the Department of Physiology, S.P. Medical College, Bikaner on hundred subjects i.e. fifty chewing tobacco users (study group) and another fifty chewing tobacco non-users who should not be active or passive smokers (control group). The chewing tobacco nonusers & users was twenty five subjects each in group I (18-35 yrs) and group II (36-55yrs). Results: The present study shows that chewing tobacco users have significantly higher Hb level, RBC count and TLC. The results of differential count shows that they even have significantly higher percentage of neutrophil in their blood. Moreover, lymphocyte and monocyte percentage in their blood are significantly lower. Platelets also significantly decreases in chewing tobacco users. The difference of mean value of Hb, RBC, TLC, Neutrophils, Lymphocytes, Monocytes and Platelets in chewing tobacco non-users & users is statistically highly significant in both group I and group II but the difference of mean value of Eosinophils and Basophils is statistically non significant in both group I and group II. Conclusion: The present study suggests that in case of individuals using chewing tobacco, the assessment of hematological parameters or screening of anaemia should be dealt with caution. This is because altered hematological profile due to tobacco use by the subject may lead to misleading interpretations.
Modeling and analysis of SynRM for hybrid electric vehicle application

In this thesis, the performance of a 4-pole SynRM is evaluated and compared to a reference 8-pole PMSM of the same size, where the machines are used in a hybrid electric vehicle (HEV) application. In order to perform a performance comparison between the machines, a design of the SynRM rotor is developed. The design is determined by using two different Mathematical Models that provides the size and position of the rotor air barriers and iron segments. The final comparison between the SynRM and the PMSM shows that if the machines operates with the same current density in the stator windings, the average torque produced by the SynRM is approximately one third of the torque produced by the PMSM. If both machines are run with the same stator current, the average torque produced by the SynRM is slightly less than half of the torque in the PMSM and the torque ripple can be reduced to levels similar to the ones in the PMSM. The low performance is mainly due to rapid saturation along the d-axis, therefore, making the current angle one important factor. The efficiency is also slightly lower in the SynRM compared to the PMSM. As expected, when the machine is operated along the MTPA line, it shows improvement in efficiency and reduction in losses. The efficiency of the SynRM is only a few percent less than the efficiency of the PMSM. Overall, more study is needed in the field, mainly to see how an increased size and proper control affects the system. But also to see what impact higher insulation ratios have on the machine. The alignment of the air barriers in the rotor against the stator slots is the single variable that effects the torque ripple the most. The SynRM also shows signs of saturation for low current, an issue that probably can be handled by the use of control strategies such as the MTPA combined with an increased rotor diameter. The saturation issue may also be reduced if it is being considered when developing a rotor design. Overall, the results in this thesis indicates that the SynRM is not a valid replacement for the PMSM in HEV applications with the design presented in this thesis.
Mixture Augmented Lagrange Multiplier Method for Tensor Recovery and Its Applications

The problem of data recovery inmultiway arrays (i.e., tensors) arises in many fields such as computer vision, image processing, and traffic data analysis. In this paper, we propose a scalable and fast algorithm for recovering a low-n-rank tensor with an unknown fraction of its entries being arbitrarily corrupted. In the new algorithm, the tensor recovery problem is formulated as a mixture convex multilinear Robust Principal Component Analysis (RPCA) optimization problem by minimizing a sum of the nuclear norm and the l(1)-norm. The problem is well structured in both the objective function and constraints. We apply augmented Lagrange multiplier method which can make use of the good structure for efficiently solving this problem. In the experiments, the algorithm is compared with the state-of-art algorithm both on synthetic data and real data including traffic data, image data, and video data.
Hybrid harmony search with great deluge for UUM CAS curriculum based course timetabling

Producing university course timetabling is a tough and complicated task due to higher number of courses and constraints. The process usually consisted of satisfying a set of hard constraints so as a feasible solution can be obtained. It then continues with the process of optimizing (minimizing) the soft constraints in order to produce a good quality timetable. In this paper, a hybridization of harmony search with a great deluge is proposed to optimize the soft constraints. Harmony search comprised of two main operators such as memory consideration and random consideration operator. The great deluge was applied on the random consideration operator. The proposed approach was also adapted on curriculum-based course timetabling problems of College of Arts and Sciences, Universiti Utara Malaysia (UUM CAS). The result shows that the quality of timetable of UUM CAS produced by the proposed approach is superior than the quality of timetable produced using the current software package.

Change-point analysis in environmental time series

Change-points are present in many environmental time series. Time variations in environmental data are complex and they can hinder the identification of the so-called change-points when traditional models are applied to this type of problems. In this study, it is proposed an alternative approach for the application of the change-point analysis by taking into account this data structure (seasonality and autocorrelation) based on the Schwarz Information Criterion (SIC). The approach was applied to time series of surface water quality variables measured at eight monitoring sites.
STUDY OF SINGLE AND COUPLED-BUNCH INSTABILITIES FOR NSLS-II ∗

We study single and coupled-bunch instabilities for the NSLS-II storage ring with a recently developed parallel tracking code. For accurate modelling of the coupled-bunch instability, we investigate improvements to current point-bunch models to take into account finite bunch-size effects. Accurate modelling of single and coupled-bunch instabilities is of crucial importance for the machine performance of light sources such as NSLS-II, that provide high current beams. The complexity of the model consists in the accurate calculation of the impedance of the various components of the ring that can excite single and multibunch instabilities via short and long range wakefields. Moreover, a full account of the coupling between transverse and longitudinal dynamics must be taken into account to study effects such as chromaticity and Landau cavity effects. A parallel algorithm for the study of single and coupled-bunch instabilities has been implemented in a particle tracking code. The theoretical framework for single bunch instabilities is the same used in the code TRANFT, while for coupled-bunch instabilities a self-consistent algorithm has been implemented to allow the study of finite bunch-size effects and multibunch effects in arbitrary filling modes. In this paper we present numerical studies of the microwave instability for NSLS-II and discuss themore » self-consistent algorithm for simulation of coupled-bunch instabilities. « less
Supply Chain Networks and R&D Investments

This paper presents the empirical evidence that supply chain networks play a central role in automotive parts suppliers’ Research and Development (R&D) investment specically in the Korean automotive industry. First, dynamic patterns show how network structures, dened by exclusiveness and the identity of partnerships, can aect the level of endogenous sunk costs consistent with Sutton (1991). Second, I test the stability of the supply chain by eigenvalue approaches of the Laplacian matrix. Then the network eects on suppliers’ R&D decisions are estimated using panel data techniques. Due to the stability of the supply chain, network measures are time-invariant and thus cannot be estimated by the xed eects estimator. Instead, the Fixed Eects Filtered estimator (Pesaran and Zhou, 2013) is used which can estimate both time-variant and time-invariant regressors consistently. The results suggest that the identity of partners, exclusiveness and information ows between competitors are important factors in suppliers’ R&D strategy. In addition, I nd that internal R&D and external R&D are substitutes when supplier has an exclusive contract.
Optimal Currency Composition for China's Foreign Reserves: A Copula Approach

This paper investigates the optimal currency composition for a country's foreign reserves. In the context of China, we examine the asymmetric, fat-tail and complex dependence structure in distributions of currency returns. A skewed, fat-tailed and pair-copula construction is then built to capture features of higher moments. In a D-vine copula approach, we show that under the disappointment aversion effect, the central bank in our model can achieve sizeable gains in expected economic value from switching from the mean-variance to copula modelling. We find that this approach will lead to an optimal currency composition that allows China to have more space for international currency diversification while maintaining the leading position of the US dollar in the currency shares of China's reserves.

Environmental Variables of the Seti Gandaki River Basin Pokhara, Nepal

Present paper focuses on the spatio-temporal variations and correlations among the environmental variables of the Seti Gandaki River basin, Pokhara, Nepal. A total of five sites, three along the river and two in tributaries were selected for this study. Water sampling was done fortnightly for environmental variables following standard methods during July 2011 to June 2012. Mean and standard deviation of the environmental variables revealed that the depth (0.9 ± 0.3), pH (8 ± 0.4), total phosphates (PO4) (0.10 ± 0.03) and nitrates (NO3) (0.13 ± 0.04) were normally variable among the sites. But the discharge (40.00 ± 37.00), width (32.30 ± 13.00), turbidity (81.40 ± 51.00), transparency (29.10 ± 15.00), conductivity (166.00 ± 80.00), water temperature (18.00 ±4.00), dissolved oxygen (DO) (8.00 ± 2.00), free carbon dioxide (CO2) (7.00 ± 2.00) and total alkalinity (98.00 ± 22.00) varied among sites equally. Correlation coefficient between the sites and environmental variables revealed that sites were found significantly correlated with water conductivity (r2 = 0.6), DO (r2 = -0.52), and free CO2 (r2 = 0.6); depth of water with width (r2 = 0.94), discharge (r2 = 0.96), turbidity (r2 = 0.71), transparency (r2 = -0.62), water temperature (r2 = 0.60), pH (r2 = -0.52) and DO (r2 = -0.48); water temperature with pH (r2 = -0.54), DO (r2 = -0.79), free CO2 (r2 = 0.69), total alkalinity (r2 = -0.58), total PO4 (r2 = 0.54) and NO3 (r2 = 0.62), etc. The enhancement of turbidity, conductivity, free CO2, phosphates and nitrates, while, suppression of transparency, pH and DO at the urban site indicated the urban influence.

Bundle Gerbes and Surface Holonomy

Hermitian bundle gerbes with connection are geometric objects for which a notion of surface holonomy can be defined for closed oriented surfaces. We systematically introduce bundle gerbes by closing the pre-stack of trivial bundle gerbes under descent. Inspired by structures arising in a representation theoretic approach to rational conformal field theories, we introduce geometric structure that is appropriate to define surface holonomy in more general situations: Jandl gerbes for unoriented surfaces, D-branes for surfaces with boundaries, and bi-branes for surfaces with defect lines.
The effectiveness of a coping-focused prevention approach

This article focuses upon a new preventive approach designed to improve personal stress management skills. The Coping Enhancement Training (CET) is derived from the Couples Coping Enhancement Training (CCET) and encompasses both an individual and a dyadic aspect. In this study, only the individual element is described. The training is based upon the transactional stress concepts of Lazarus and his coworkers and the further development of this approach by Perrez and Reicherts (1992). Personal coping skills are practiced over a six-hour period by means of theoretical, diagnostic and practical work. This article presents the rationale and content of the program, as well as data concerning the effectiveness of this approach after a period of two years. The data shows that subjects participating in the program displayed better individual coping skills (e.g. active problem-solving and positive self-verbalization) after the training and that they relied upon dysfunctional coping strategies (e.g. rumination and blaming strategies) less often even after two years.
Habitat use of the fungivorous beetle Bolitophagus reticulatus (Coleoptera: Tenebrionidae): Effects of basidiocarp size, humidity and competitors

Habitat use of Bolitophagus reticulatus (L.) (Coleoptera: Tenebrionidae), living in the basidiocarps of Fomes fomentarius (L.) Kickx, was investigated in three forest areas in south-eastern Norway: (1) a continuous, coniferous forest, (2) an agricultural area with mostly deciduous forest islands in a matrix of cultivated land and (3) a homogeneous, old deciduous forest stand. B. reticulatus was almost exclusively found inside dead basidiocarps. The size of the basidiocarp was the most important variable for predicting the probability of B. reticulatus presence in the basidiocarps from all three study areas. Drier basidiocarps had a higher probability of beetle presence than the wetter ones. Basidiocarps situated above the ground level had a higher probability of beetle presence than those close to or on the ground level. In the first study area, the presence of Cisidae was found to reduce the probability of B. reticulatus presence perhaps as a result of competition. The disappearance of beetles from previously inhabited basidiocarps seemed to be due to depletion of resources.
Eigenvalue estimates for the weighted laplacian on a riemannian manifold

Given a complete Riemannian manifold M and a smooth positive function w on M, let L = -L1 V(log w) acting on L2(M,wdV). Generalizing techniques used in the case of the Laplacian, we obtain upper and lower bounds for the first non-zero eigenvalue of L, for M compact, and for the bottom of the spectrum, for M non-compact. 1. Introduction. Let M n be an n-dimensional, complete Riemannian manifold. The Laplace operator on M, LI, can be defined as the differential operator associated to the standard Dirichlet form where I I is the norm induced by the Riemannian inner product and dV is the volume element on M n . Now let w be a given smooth strictly positive function on M n, that will be referred to as a weight function. If we replace the measure dV with the weighted measure w dV in the definition of Q, we obtain a new quadratic form Qw , and we denote by L the elliptic differential operator on induced by Qw . In this sense L arises as a natural generalization of the Laplacian. It is clearly symmetric and positive and extends to a positive self-adjoint op(*) Indirizzo dell’A. : Dipartimento di Matematica, Universita di Milano, via Saldini 50, 20133 Milano, Italy. 1991 Mathematics Subject Classification.

Secret Sharing , Functional and Security Requirements

This paper proposes a scheme for password management by storing password encryptions on a server. The method involves having the encryption key split into a share for the user and one for the server. The user’s share shall be based solely on a selected passphrase. The server’s share shall be generated from the user’s share and the encryption key. The security and trust are achieved by performing both encryption and decryption on the client side. We also address the issue of countering dictionary attack by providing a further enhancement of the scheme.
Agrobacterium-mediated transformation of watermelon (Citrullus lanatus)

Transformation of watermelon (Citrullus lanatus cv. Zaojia) using Agrobacterium tumefaciens strain EHA105 containing the plasmid pRD400 carrying Pti4 gene was studied in this work. Proximal cotyledons as explants were pre-cultivated for two day in the dark and it was found that the best condition for transformation of watermelon was the use of bacteria at a concentration of OD600 0.3, inoculation for 10 min and 72 h of co-cultivation. Kanamycin as a selective agent in different concentration (75, 100 and 125 mg/l) was tested. Transformed explants on medium supplemented with 100 mg/l kanamycin received a higher efficiency of shoots with transgenic DNA (9.17%). Using specific primer to Pti4 gene, PCR product with a size of 680 bp was amplified when the genomic DNA extracted from the transformants were used as templates. A total of 148 plants with percentage 10.28% showed positive results using PCR analysis and subsequently all were regenerated into whole plants.
A Study of Used Swage Ball Effect on Head Stack Performances

This research describes the study of HSA efficiency as a result of recycling used swage ball. Key Parameter Output Variables (KPOVs) of HSA which consists of gram load, arm height, swage torque and resonance were investigated using statistical methodology. Moreover, changes in physical characteristics of swage ball after swaging process were also examined. The results of the analysis showed that only swage ball having a big diameter underwent a physical characteristic change, i.e., ball roundness was decreased. However, KPOVs of HSA using those swage balls were not altered. The resonance of HSA is slightly increased, but the discrepancy is in the range of HDD servo stability margin. The results obtained could be used as guideline for the decision to implement used swage ball in head stack swaging process. Keywords : Ball Swaging / Swaging Process / Key Parameter Output Variables
One-User/One-Group Soft-Decision Aided Multiuser Detection for 2D Spread MC DS-CDMAs

We consider the uplink of a multiuser, multiple-input multiple-output (MIMO), frequency-time-domain spread, multi- carrier (MC), direct sequence code division multiple access (DS-CDMA) system. As other CDMA-like systems, the multiple access interference (MAI) effect still exists in such an MC DS-CDMA system. To mitigate the MAI effect, we propose user-based and group-based layered detection schemes. Specifically, to enable a trade-off between the performance and the computational complexity, the schemes only use one user's/group's soft decisions for user-based/ group-based layered detection. The results of simulations demonstrate that the proposed schemes outperform existing approaches, and their computational complexity is modest.
SEASONAL PATTERNS OF PHENYLALANINE AMMONIA-LYASE ACTIVITY AND TOTAL PHENOL AND TANNIN CONTENTS IN Stryphnodendron adstringens (Mart.) Coville

We performed analyses of the leaves and stem bark of Stryphnodendron adstringens , a Brazilian Cerrado plant, to examine the seasonal patterns of phenylalanine ammonia-lyase activity and total phenol and tannin contents in 16 adult individuals under field conditions. The measurements of gas exchange parameters, including net photosynthesis, transpiration and stomatal conductance, as well as the photosynthetic photon flux density, leaf temperature, vapor pressure deficit and leaf water potential were also performed. The results were subjected to a principal component analysis. The values obtained for stomatal conductance, net photosynthesis, transpiration, water use efficiency, minimum water potential and photosynthetic photon flux density were higher in the rainy season, while the maximum water potential and vapor pressure deficit in the atmosphere were similar between seasons. The seasonal variations in gas exchange characteristics were influenced by changing weather conditions and were positively correlated with higher air temperatures, rainfall amounts and relative air humidity and negatively correlated with increased insolation. There was no correlation between the maximum leaf water potential and any of the weather variables. Phenylalanine ammonia-lyase activity was similar in the dry and rainy seasons, and higher levels of total phenols and tannins were observed in the dry and rainy seasons, respectively. Phenylalanine ammonia-lyase activity and total phenol contents were negatively influenced by temperature and rainfall in the dry season, and the total tannin contents were mainly correlated with higher temperatures and a lower influence of rainfall in the rainy season.
