Aim: The purpose of this study was to compare static and dynamic warm-up regimes on lower limb muscle power and thereby the perform-ance of the individual. Methodology: Twenty eight (28) subjects were assigned into groups consisting of 2 members. From each group, 1 subject performed the static stretching and the other subject performed dynamic stretching as warm-up. This was followed by non-counter movement jumps on a force platform and the vertical jump heights were recorded. Data were analysed using one-way ANOVA and paired t-test at 0.05 alpha. Result: The results showed that dynamic stretching as warm-up causes significant increase (p=0.01) in the vertical jump height as compared to static stretching (p=0.03). Discussion: The increase in vertical jump height could be related to the increase in force pro-duction which plays an important role during the vertical jump test. On the other hand the decrease in vertical jump height following static stretching could be attributed to a decrease in the force production in the muscles. Conclusion: Dynamic warm-up increases the vertical lump height, whereas static stretching decreases the jump height of the athlete.

OBJECTIVE： In continuation to the growing evidence for therapeutical potential of Desmostachya bipinnata （Linn） Stapf, the current pharmacological study was carried out to evaluate the diuretic and laxative activity of its hydro-alcoholic extract in rats. METHODS： The hydro-alcoholic extract of D. bipinnata whole plant was prepared by using Sox- hlet extractor and subjected to analysis by standard preliminary phytochemical tests. Evaluation of both diuretic and laxative activity was carried out using standard methods as reported earlier. Frusemide （20 mg/kg） was served as positive control for diuretic activity and sennosides （10 mg/kg） served as negative control for laxative activity. RESULTS： The hydro-alcoholic extract showed significant diuretic activity and was found to be the most potent in increasing the urinary output at 500 mg/kg when the effect was compared with that of the standard frusemide （P〈0.01）. Moreover, this extract was found to be most effective in increasing urinary electrolyte concentration （Na＋, K＋, and Cl-） at both doses tested. Whereas the results for laxative activity showed minimal increase of feces output at the dose of 500 mg/kg and the increase was negligible when compared with that of the standard drug sennosides. CONCLUSION： Altogether, the above significant findings validate and support its folkloric diuretic use and lend pharmacological credence to the ethno-medical use of this plant in traditional system of medicine, which demands further studies to investigate its active constituents, as well as its use and safety.

In software industry the major problem encountered during project scheduling is in deciding what proportion of the resources has allocated to the testing phase. In general it has been observed that about 40%-50% of the resources need to be allocated to the testing phase. However it is very difficult to predict the exact amount of effort required to be allocated to testing phase. As a result the project planning goes haywire. The project which has not been tested sufficiently can cause huge losses to the organization. This research paper focuses on finding a method which gives a measure of the effort to be spent on the testing phase. This paper provides effort estimates during pre-coding and post-coding phases using neural network to predict more accurately.

The nature and extent of genetic diversity were assessed among 23 parents of pigeonpea hybrids employing Mahalanobis D2 statistics. Based on relative magnitude of D2, the genotypes were grouped into five different non-overlapping clusters. Cluster III, having 8 genotypes, emerged with highest number of entries;cluster I, II and V were constituted by four genotypes each while cluster IV, comprising three genotypes, had least number of entries. The highest contribution in manifestation of genetic divergence was exhibited by 100-seed weight followed by pods per plant, days to maturity, harvest index, biological yield per plant, days to 50% flowering and seed yield per plant. The maximum intra-cluster distance was observed for cluster III, followed by cluster IV, cluster I and cluster V. The highest inter-cluster distance was recorded between cluster II and IV followed by cluster I and IV and cluster V and II. The crossing between entries belonging to cluster pairs having large inter-cluster distance and possessing high cluster means for one or other characters to be improved may be recommended for isolating desirable recombinants in the segregating generations in pigeonpea. Considering the mean performance for different characters of genotypes belonging to diverse clusters, the promising genotypes identified were NDA 2, NDA 7-11, IPA 208 and NDA 5-14 of cluster I;NDA 3-3, NDA 98-6, Amar and NDACMS 1-3A of cluster II;NDACMS 1-4A, NDACMS 1-6A and ICP 870 of cluster IV and NDA 96-6, ICP 2155, NDA 8-6 and NDAGC 1010 of cluster V for exploitation as parents in hybridization programme for development of superior pigeonpea hybrid cultivars.

Background Off-pump coronary artery bypass grafting (CABG) is becoming increasingly popular world - wide. But it is not always feasible. Current cardioplegic techniques do not consistently avoid myocardial ischemic damage. So we use on pump beating heart technique to supplement off-pump CABG. Methods Based on 860 off-pump CABG cases between Aug 1998 to Aug 2000. From Aug 1999 to Aug 2000, 46 CABG cases were performed with on pump beating heart technique at Mani-pal Hospital Heart Foundation, Bangalore, India. All surgeries were performed through a median sternotomy. Exposure techniques were tailored to individual vessels and cardiac regions and local immobilization was performed with octopus. Vascular control was achieved with occluders and shunts. Total cardiopulmonary bypass (CPB) was established before or during CABG and normolthemia was used. Results Among 46 on -pump beating heart CABG patients, 26 patients used CPB before or during OP - CABG because of unstable hemodynamics and electric instability , 7 had very deep intramyocardial left anterior descending arteries, 5 patients had poor LV function (LVEF < 30 % ), 8 patients had cardiomegaly. The average number of grafts was 3.5. No operative mortality. Three patients had postoperative myocardial infarction. Anesthetic time 4. 5±1. 2 hours, extubation time 10±2. 5 hours, blood lost 680±230 mL, blood requirement 540±150 mL, preoperative LVEF 50. 3±13 % , postoperative LVEF 64. 1±14 %, ICU stay 1. 5±0. 5 days, hospi- tal stay 9.2±1.8 days. Conclusion Complete coronary revascularization with on pump beating heart is a supplement for off - pump CABG when it is not feasible. It eliminates intraoperative globe myocardial ischemia and avoids transient myocardial injury during cardioplegic arrest and myocardial reperfusion.

Many existing real time commit protocols try to improve system performance by allowing a committing cohort to lend its data to an executing cohort, thus reducing data inaccessibility. They block the borrower from sending WORKDONE/PREPARED message and restrict them from lending data so that transaction abort chain is limited to one. Thus, transaction execution time increases. This paper proposes a modified real time commit protocol for distributed real time database systems (DRTDBS), Allow Commit Dependent and in Time borrowers for Incredible Value added data lending without extended abort chain (ACTIVE), where borrower cohorts are categorized as commit and abort dependent. Further, the commit dependent borrowers can lend data to executing cohorts with still limiting the transaction abort chain to one only and reducing the data inaccessibility. Also, an incoming executing cohort having borrowing factor greater than one can only borrow the dirty data items from lender. This minimizes the fruitless borrowing by the cohort. The performance of ACTIVE is compared with PROMPT, 2SC and SWIFT protocols for both main memory resident and disk resident databases with and without communication delay. Simulation results show that the proposed protocol improves the system performance up to 4% as transaction miss percentage.

Silver nanoparticles in the form of silver based chemicals trace back their origin to time immemorial since the dilute forms of silver nitrate were used in place of antibiotics before they dominated the field of medicine. But, it has now become necessary to explore the anti-microbial properties of silver based chemicals again due to the microbes gaining resistance against the wide range of present day antibiotics. The advancements in the field of medicine and technology started to coalesce to combat the adaptability of microbes as they successfully become tolerant to antibiotics and it manifested in the form a current technology, Nanomedicine. Nanomedicine deals about the medicines at a nano scale to rarefy the intensity of medicine to unaffected tissues and reduce the volume of medicine used. In the present context, our attempt is to develop potential anti-microbial particles in the form of silver nanoparticles by using the biological phenomena which we call Green synthesis an eco-friendly approach to conventional chemical synthesis. The enzymatic machinery of the olive seeds has been exploited to produce silver nanoparticles and test their efficacy as antifungal agents before we characterized their physical properties using UV-Vis, TEM, and FTIR analysis. The efficacy of these particles as antagonists on fungal pathogen Aspergillus niger a causative agent of Aspergillosis in human beings and is promising and they have a lot of scope for the purpose and hope the technology leads the next generation of anti-microbials.
