Manoj Kumar Sharma, L. N. Suman, Pratima Murthy, P. Marimuthu
Open Journal of Psychiatry (OJPsych) , 2012, DOI: 10.4236/ojpsych.2012.24033
Abstract: Background: Abstinence and anger control are promoted as ways to improve quality of life. Trait anger has been seen as one casual factor for alcohol related aggression and poor quality of life. The present study assesses anger control, quality of life and its relation with trait anger among alcohol dependents, abstainers & social drinkers. Material & Method: 150 subjects (50 subjects in each group) in the age range of 20 - 45 years were taken for the study. Semi-structured interview schedule, State-Trait Anger Expression Inventory-2, WHOQOL-BREF were administered in individual setting. Results: Dependent alcohol users and abstainers reported the significant impact of alcohol use on family & occupational functioning. Quality of life has correlation with anger control (in/out), trait anger, temperament & reaction in the control & abstainers group, whereas quality of life has negative correlation with trait anger expression among the alcohol group. Conclusions: Alcohol use has been associated with the trait anger expression and poor quality of life. It has implications for promoting alcohol abstinence, in improving quality of life and in anger control.
Antioxidative and hypocholesterolemic effect of Lactobacillus casei ssp casei (biodefensive properties of lactobacilli)
Kapila Suman,Vibha,Sinha P
Indian Journal of Medical Sciences , 2006,
Abstract: BACKGROUND: A positive correlation between an individual′s cholesterol level and development of CHD has been suggested. Low levels of high-density lipoprotein cholesterol (HDL-C) and high levels of low-density lipoprotein cholesterol (LDL-C) are important risk factors and oxidation of LDL has been implicated as an initiator of atherosclerosis. AIM: Attempts are being made worldwide for the search of effective antioxidants that can prevent oxidation of LDL. Role of fermented milk and culture containing dairy products as effective antioxidants and their potential hypocholesterolemic effect is the focus of research. Keeping this in view, the various lactobacilli cultures were screened for their in vitro antioxidative activity. Lactobacillus casei ssp casei showing maximum antioxidative activity was selected for carrying out in vivo studies. SETTINGS AND DESIGN: Six groups of Wistar albino rats were fed on diets containing 20% fresh or oxidized soybean oil supplemented with 5% lyophilized culture or fermented milk prepared using L. casei ssp casei for a period of 90 days. The plasma was separated in different lipoprotein fractions and analyzed for cholesterol content and thiobarbituric acid reactive substances (TBARS). RESULTS: The cholesterol levels were less in plasma of groups fed on fermented milk by 2-11% and by 15-25% in groups fed on lyophilized culture as compared to group fed on skim milk. The levels of TBARS were lower in the LDL fraction of plasma in rats fed on fermented milk or culture than the control group fed on skim milk. CONCLUSIONS: The results depict the cholesterol-lowering and antioxidative potential of Lactobacillus casei ssp casei for their application as dietary adjunct.
Network Community Detection on Metric Space
Suman Saha,Satya P. Ghrera
Computer Science , 2015, DOI: 10.3390/a8030680
Abstract: Community detection in a complex network is an important problem of much interest in recent years. In general, a community detection algorithm chooses an objective function and captures the communities of the network by optimizing the objective function, and then, one uses various heuristics to solve the optimization problem to extract the interesting communities for the user. In this article, we demonstrate the procedure to transform a graph into points of a metric space and develop the methods of community detection with the help of a metric defined for a pair of points. We have also studied and analyzed the community structure of the network therein. The results obtained with our approach are very competitive with most of the well-known algorithms in the literature, and this is justified over the large collection of datasets. On the other hand, it can be observed that time taken by our algorithm is quite less compared to other methods and justifies the theoretical findings.
Nearest Neighbor search in Complex Network for Community Detection
Suman Saha,S. P. Ghrera
Computer Science , 2015,
Abstract: Nearest neighbor search is a basic computational tool used extensively in almost research domains of computer science specially when dealing with large amount of data. However, the use of nearest neighbor search is restricted for the purpose of algorithmic development by the existence of the notion of nearness among the data points. The recent trend of research is on large, complex networks and their structural analysis, where nodes represent entities and edges represent any kind of relation between entities. Community detection in complex network is an important problem of much interest. In general, a community detection algorithm represents an objective function and captures the communities by optimizing it to extract the interesting communities for the user. In this article, we have studied the nearest neighbor search problem in complex network via the development of a suitable notion of nearness. Initially, we have studied and analyzed the exact nearest neighbor search using metric tree on proposed metric space constructed from complex network. After, the approximate nearest neighbor search problem is studied using locality sensitive hashing. For evaluation of the proposed nearest neighbor search on complex network we applied it in community detection problem. The results obtained using our methods are very competitive with most of the well known algorithms exists in the literature and this is verified on collection of real networks. On the other-hand, it can be observed that time taken by our algorithm is quite less compared to popular methods.
A Methodology for Selection of Optimum Power Rating of Propulsion Motor of Three Wheeled Electric Vehicle on Indian Drive Cycle (IDC)
Prasun Mishra,Suman Saha,H. P. Ikkurti
International Journal on Theoretical and Applied Research in Mechanical Engineering , 2013,
Abstract: Optimum power rating of propulsion motor is an important issue for designing efficient drive train for a three wheeled battery operated electric vehicle application on standard drive cycle like Indian Drive Cycle of Indian urban and suburban areas. This paper deals with proper estimation of power rating of electric motor by root means square technique while considering the limitations of overloading and under loading operation of motor used in electric vehicle along with some specified design parameters, aiming towards better performance than that of a conventional IC engine driven vehicle. Dynamics of three wheeled vehicle is simulated on MATLAB/Simulink environment under a sequence of road grade angle variation in Indian Drive cycle (IDC), which is formulated by Automotive Research Association of India, Pune. Using simulated vehicle dynamics, power rating of the motor is estimated so that it can be operated efficiently and safely throughout the entire Indian drive Cycle.

Suman Kumar S.P,Vijay Anand
International Journal of Next-Generation Networks , 2010,
Abstract: Digital Video Content is now pervasive and services like IPTV are gaining traction on handheld devices too. Android, a software platform from Google, pioneering middleware and applications forhandheld devices does not offer support for content management services by design.Motivated by these observations, we propose an aggregate model software platform to offercontent management and value added services (VAS) like IPTV on android. The outline of paper is asfollows: First, we discuss few related works to investigate and analyze industry-wide content managementand delivery practices. Second, we discuss few characteristics of android architecture and detail theconstraints associated with middleware to offer such VAS. Consequently, we describe the proposedsoftware platform which addresses key inherent challenges like Efficiency, Extendibility and Securitywhile achieving efficient content delivery. The Module Interconnection Architecture can be visualized tobe constituted by three basic building blocks, namely: VAS Content Management framework, IPTVframework and Application Services framework. The architecture employs a different perspective ofclassifying content based on applications. We point out the need and rationale behind such aclassification to correlate in an end-2-end IPTV architecture. We show the benefits of using theApplication Services framework to ensure smooth and swift portability onto various flavors of android.Finally, we conclude by detailing some use-cases indicating content management services like ElectronicService Guide (ESG) on Android..

International Journal of Next-Generation Networks , 2010,
Abstract: IP Multimedia Subsystem (IMS) known for its prominent service delivery is paving way forapplications like Video Voice over IP (VVOIP) on handheld devices too. Android, a software platformfrom Google, pioneering in middleware and applications domain of handheld devices does not offersupport for IMS services by design.Motivated by these observations, we present novel scalable architecture to cater IMS basedservices on Android. First, we discuss few related works to investigate and analyze the IMS and the roleof SIP in IMS services. Second, we discuss few characteristics of android architecture and detailconstraints associated with middleware sub-system to cater IMS services. Consequently, we describe theproposed architecture addressing inherent challenges like QoS, Extendibility and Security encounteredwhile offering IMS based services. The architectural framework design reduces time-to-deployment byusing a layered approach encompassing three layers, namely: QoE Engine, Advanced IMS Service Core(A-IMS) and Application Services Engine (ASE). The A-IMS core is responsible to provide End-2-Endefficient service delivery of IMS services like VOIP. We point out the benefits of using the ASE andgeneric media management and control interface (GMMCI) to ensure smooth and swift portability ontodifferent flavors of android. Finally, we conclude by detailing some use-cases of future IMS services likeVideo Sharing/Video Recording in an on-going Video Telephony Call

Vikas Nayak,Suman Banger,U. P. Verma
Conference Papers in Science , 2014, DOI: 10.1155/2014/807893
Abstract: The quantum mechanical calculations based on density functional theory (DFT) have been performed to study ground state structural and electronic properties of BeH2 and along with doping of two (BeH2 + 2H) and four (BeH2 + 4H) hydrogen atoms. The generalized gradient approximation (GGA) has been employed for the exchange correlation energy. The most stable space group of BeH2 is Ibam. Its optimized equilibrium unit cell volume, bulk modulus and its first-order pressure derivative, and electronic properties have been obtained. Our predicted unit cell parameters for BeH2?? ??, ??, and ?? are in very good agreement with the earlier reported experimental and theoretical results. The electronic band structure of BeH2 shows its behavior as an insulator. The stability of BeH2 along with doped hydrogen atoms increases, while the energy band gap decreases with the increase in number of doped hydrogen atoms. On these bases, we predict that BeH2 is a promising material for hydrogen storage. 1. Introduction Energy storage for the future is a great concern for the researchers and scientists. We need materials like metal hydrides for various potential applications, that is, for hydrogen storage, in fuel cells and internal combustion engines, as electrodes for rechargeable batteries, and in energy conversion devices. The metal hydrides for hydrogen storage need to be able to form hydrides with a high hydrogen-to-metal mass ratio, but they should not be too stable, so that the hydrogen can easily be released without excessive heating. Beryllium and magnesium and beryllium-magnesium-based hydrides contain a relatively high fraction of hydrogen by weight but need to be heated ~250 to 300°C in order to release the hydrogen. The alkali-metal and alkaline-earth-metal hydrides represent series with largely ionic bonding. The high pressure behavior of the alkali-metal monohydrides is expected to parallel of the alkali-metal halides [1]. However, there is no systematic high-pressure study on the alkaline-earth-metal hydrides. If becomes metallic when subjected to high pressures, one can entertain the possibility that its properties could resemble those of metallic hydrogen. is commonly considered as a covalent hydride with a postulated polymeric crystal structure made up of H-bridged chains. However, mainly owing to experimental difficulties in the synthesis of the material, the structure has long remained unknown [2]. Crystalline has been synthesized and the structure has been established as body centered orthorhombic by synchrotron-radiation-based powder X-ray diffraction

Advances in Nanoparticles (ANP) , 2018, DOI: 10.4236/anp.2018.74007
Abstract: In the present study silver nanoparticles (AgNPs) were synthesized using leaves of bamboo plant, Bambus vulgaris and the size of the nanoparticles was confirmed using XRD, EDAX, SEM, TEM, PSA analysis. The antimicrobial activity of the synthesized NPs showed a good antibacterial activity against the waterborne isolates, E. coli, Staphyllococcus aureus, Vibrio cholera and Salmonella sp. Further the anti algal activity of the NPs was tested against the algae, Dictyosphaerium pulchellum, and Algoriphagus chordate. The SEM studies revealed that the AgNPs breaks the cell wall of algae and inhibits the growth. The safe dose of AgNPs can be used in aquaculture farms, household water tanks and other small water bodies to wipe out waterborne pathogens and algal bloom.
The In-Terrorem Value of Science: Bisphenol-A Litigation and an Empirical Assessment of Science as a Collective Litigation Tool  [PDF]
Suman Kakar, Sanjeev Sirpal
Beijing Law Review (BLR) , 2011, DOI: 10.4236/blr.2011.22006
Abstract: This paper examines the role that science plays as a tool in collective litigation to substantiate claims. Scientific data and expert testimony are often included to buttress a claim and the admissibility of such evidence is often a conse-quence of the extant evidentiary rules and their application. The article will focus on the multidistrict litigation con-cerning Bisphenol-A (“BPA”) as a case study of the phenomena of scientific tailoring of evidence and its admissibility. BPA is a compound included in the synthesis of plastics and is found in food containers, plastic bottles, and ep-oxy-based coatings used to avert the rusting process of food containers. There is a negligible amount of BPA in several food and beverage products. Several countries along with the US Food and Drug Administration (FDA) and Environ-mental Protection Agency (EPA) have marshaled scientific studies that demonstrate the lack of any definable negative health effect attributable to an exposure to trace amounts of BPA. Notwithstanding the conclusions of these scientific inquiries, opponents have asserted that BPA exposure results in an alteration of embryonic hormone levels, thereby impacting their development and later reproductive function. This article will address these issues in addition to the salient question of what role science plays as a tool for collective litigation.
