Abstract: The ethnomedicinal practices appear to be a part of traditional system of treatment for domestic cattle in remote areas of Nepal. The knowledge of local healers with the utilization of biological resources in various ailments is still survived and is communicated verbally to limited family members. As a result, this knowledge is at threatened stage. Now days, documentation of traditional knowledge is receiving much attention. The study carried out in seven village development committees of Morang district concerns with the traditional uses of crude drugs obtained form 37 plant species belonging to 24 families which are used for the treatment of 21 common ailments of domestic cattle. Participatory Rural Appraisal (PRA) method was applied to collect the data. The information on the correct botanical sources, family, local name, plant part used, method of preparation and method of application of different crude drugs were investigated in this study.
WiMAX or LTE: Which Technology to Adopt? A Comprehensive Comparative Study
Suhas Raut
Communications of the IBIMA , 2009,
Abstract: The industry landscape in telecommunications is changing rapidly at the moment. Services are increasingly shifting from voice to data and from circuit-switched to packet-switched ones. LTE and WiMAX are the two technologies poised to dominate next generation mobile networks. Battle between LTE & WiMAX technologies is already heating up with WiMAX being ahead due to availability of standards through IEEE 802.16 and is up and running but lacks in substantial roll out plans due to cost. On the contrary, LTE upgrades from 3G networks are rumored to be as simple as slotting in a new card in the rack. Researchers and business community is divided over the choice of LTE and WiMAX. Few researchers feel that 3G LTE can bring substantial technologies and economical benefits to operators deploying mobile networks beyond 3G. This paper presents a comprehensive comparative study to help arrive at the choice between LTE and WiMAX.
Management Framework for Globally Distributed Teams in IT Industry
Suhas Raut
Communications of the IBIMA , 2008,
Abstract: Software development is a highly creative and collaborative endeavor in which success requires a fine degree of coordination between many people from many different disciplines, often working across different geographies and time zones and sometimes across cultural borders. When implementing software development in a global environment, a popular strategy is the establishment of globally distributed teams.Project management owes its existence as a management discipline to the complex, high technology undertakings. Projects are complex endeavors and project outcomes are far from being certain. Software development teams are plagued by management problems that result in missed deadlines, budget overruns, and canceled projects, and effective management remains an open problem. The management aspect becomes further challenging and complicated while dealing ethical, time zone, cross cultural issues inherent to a globally distributed team. In this paper we have presented an adept management framework for globally distributed teams.

International Journal of Biomedical Imaging , 2011, DOI: 10.1155/2011/467563
Abstract: Deconvolution-based analysis of CT and MR brain perfusion data is widely used in clinical practice and it is still a topic of ongoing research activities. In this paper, we present a comprehensive derivation and explanation of the underlying physiological model for intravascular tracer systems. We also discuss practical details that are needed to properly implement algorithms for perfusion analysis. Our description of the practical computer implementation is focused on the most frequently employed algebraic deconvolution methods based on the singular value decomposition. In particular, we further discuss the need for regularization in order to obtain physiologically reasonable results. We include an overview of relevant preprocessing steps and provide numerous references to the literature. We cover both CT and MR brain perfusion imaging in this paper because they share many common aspects. The combination of both the theoretical as well as the practical aspects of perfusion analysis explicitly emphasizes the simplifications to the underlying physiological model that are necessary in order to apply it to measured data acquired with current CT and MR scanners. 1. Introduction Tissue perfusion measurement from iodinated contrast agent enhancement on CT scans was first proposed by Axel in 1980 [1]; this was based on earlier developments by Meier and Zierler [2] for measuring blood flow and blood volume. At that time, the CT-based measurements were strictly limited to research because of the low speeds and narrow coverage of the existing CT scanners. However, the introduction of perfusion CT (PCT) helped expand the utility of CT significantly since it could now provide capillary level hemodynamic information. Within about a decade, perfusion imaging techniques were also adopted in MR [3–5]. With the advent of helical scanners and faster rotating gantries (0.33–0.5?s/rotation) in conjunction with multidetector geometries which provide larger coverage, PCT has now become part of the routine screening for many diseases. Given the existing developments in perfusion imaging, the purpose of this paper is to focus on a detailed derivation of the theoretical model for deconvolution-based perfusion measurement. While the main equation of this model is well known, its derivation is spread over several publications. We therefore first present a summary of the derivation, with the aim of fully explaining the parameters and the underlying assumptions that are made. Based on the main equation of the theoretical model, we also present a guideline for the algorithmic

Abstract: Since plants are used as therapeutic agents, the present study was conducted to evaluate the phytochemical profile and antibacterial activities of extracts of. Eclipta alba and Tylophora indica .Studies on the antibacterial activity of methanol, petroleum ether and aqueous extracts of dry leaf, stem and root of Eclipta alba and Tylophora indica was evaluated using zone of inhibition studies and minimum inhibitory concentration. The microorganisms used include Escherichia coli, Micrococcus roseus and Pseudomonas flavescens . The extract exhibited antibacterial activity against these experimental strains. Methanol extracts shows higher degree of antibacterial activity than aqueous and petroleum ether extracts. The minimum inhibitory concentration ranged between 12.5mg/mL and 75mg/mL depending on microorganism and various extract. Screening of the phytochemical extracts revealed the presence of compounds like alkaloids, glycosides, tannins and flavonoids. Escherichia coli and Pseudomonas flavescens are more sensitive where as Micrococcus roseus is less sensitive to extracts of Eclipta alba and Tylophora indica. The experimental observation shows that Eclipta alba and Tylophora indica have antibacterial activity and can be used for therapeutic purposes.

Aditya, G;Raut, SK;
Memórias do Instituto Oswaldo Cruz , 2002, DOI: 10.1590/S0074-02762002000400015
Abstract: the sewage snail physa acuta is a serious threat to certain economic plants and to the purification plant of sewage works by rendering the biofilters ineffective. various attempts are being made to control it. the efficacy of the predacious water bugs sphaerodema rusticum was judged experimentally, in the laboratory in the potential control of p. acuta. it is revealed that, when supplied separately, the first, second and third instar and the adult s. rusticum did not attack p. acuta belonging to 3.1-8 mm, 5.1-8 mm, 7.1-8 mm and £ 3 mm size classes respectively. in the remaining trials predation rate varied from zero to eight (average 2.3) individuals per predator per day. in experiments with p. acuta belonging to all the size classes supplied together, none, except the first instar s. rusticum, attacked the prey individuals belonging to the lowest (£ 3 mm) size class. the first and second instar s. rusticum, in both trials did not attack p. acuta larger than 4 mm and 5 mm in shell length respectively. the water bugs belonging to the third, fourth, fifth instar and adult stages though preyed upon p. acuta with 3.1-8 mm shell length. the average rate of predation by a single s. rusticum varied from 0.14-3.08 individuals per day depending upon the size of p. acuta and the stage of s. rusticum. a single s. rusticum, irrespective of instar and adult stages, destroyed on average 4.16 p. acuta daily irrespective of sizes. it is estimated that one s. rusticum could destroy 1,360 p. acuta in its life time. the results clearly indicate that the water bug s. rusticum may be used to control the snails p. acuta.
Computer Simulation of CI Engine for Diesel and Biodiesel Blends
Laukik P. Raut
International Journal of Innovative Technology and Exploring Engineering , 2013,
Abstract: Among the alternative fuels, biodiesel and its blends are considered suitable and the most promising fuel for diesel engine. The properties of biodiesel are found similar to that of diesel. Many researchers have experimentally evaluated the performance characteristics of conventional diesel engines fuelled by biodiesel and its blends. However, experiments require enormous effort, money and time. Hence, a cycle simulation model incorporating a thermodynamic based single zone combustion model is developed to predict the performance of diesel engine. A comprehensive computer code using “C” language was developed for compression ignition (C.I) engine. Combustion characteristics such as cylinder pressure, heat release, heat transfer and performance characteristics such as work done, brake power and brake thermal efficiency (BTE) were analyzed. On the basis of first law of thermodynamics the properties at each degree crank angle was calculated. The simulated combustion and performance characteristics are found satisfactory with the experimental results.

Indian Journal of Dermatology, Venereology and Leprology , 2011,
Abstract: The Internet provides a quick access to a plethora of the medical literature, in the form of journals, databases, dictionaries, textbooks, indexes, and e-journals, thereby allowing access to more varied, individualized, and systematic educational opportunities. Web search engine is a tool designed to search for information on the World Wide Web, which may be in the form of web pages, images, information, and other types of files. Search engines for internet-based search of medical literature include Google, Google scholar, Yahoo search engine, etc., and databases include MEDLINE, PubMed, MEDLARS, etc. Commercial web resources (Medscape, MedConnect, MedicineNet) add to the list of resource databases providing some of their content for open access. Several web-libraries (Medical matrix, Emory libraries) have been developed as meta-sites, providing useful links to health resources globally. Availability of specific dermatology-related websites (DermIs, DermNet, and Genamics Jornalseek) is useful addition to the ever growing list of web-based resources. A researcher must keep in mind the strengths and limitations of a particular search engine/database while searching for a particular type of data. Knowledge about types of literature and levels of detail available, user interface, ease of access, reputable content, and period of time covered allow their optimal use and maximal utility in the field of medicine.
Differentiation of Candida dubliniensis on chrom agar and Pal′s agar
Raut S,Varaiya A
Indian Journal of Medical Microbiology , 2009,
Abstract: Difference in expression of putative virulence factors and in antifungal susceptibility among different Candida species has raised the need for species-level identification. The close relationship of Candida dubliniensis with C. albicans has led to misidentification of C. dubliniensis isolates as C. albicans . Phenotypic tests include ability to produce chlamydospore on casein agar, colony colour development on differential media CHROM agar Candida medium and ability to form hyphal fringe on Pal′s agar, have been used to differentiate these two Candida species. Fifty isolates of Candida species were recovered from various specimens (blood, urine, tissue and respiratory secretions) from diabetic and cancer patients between April and July 2007. The isolates were tested for chlamydospore production on casein agar. These were also streaked simultaneously on CHROM agar, Pal′s agar and a combination of CHROM agar supplemented with Pal′s agar for identification and differentiation of C. dubliniensis from C. albicans . On CHROM agar, 19 isolates were identified as C. dubliniensis , nine as C. albicans , 10 as C. krusei , nine as C. tropicalis and two as C. glabrata . One was indeterminate and later identified as C. dubliniensis . Out of the 20 C. dubliniensis isolates, 19 isolates exhibited hyphal fringe on Pal′s agar. On CHROM agar supplemented with Pal′s agar, 16 out of the 19 fringe-positive isolates exhibited fringe surrounding the bluish green-coloured colonies of C. dubliniensis . Additional identification tests like growth at 45oC and ability to reduce 2,3,5-triphenyltetrazolium chloride were time efficient, inexpensive and easy-to-use methods for differentiation of C. dubliniensis and C. albicans isolates. CHROM agar when supplemented with Pal′s agar gave definitive identification between C. dubliniensis and C. albicans .
