Changes Observed on Speed and Agility of Male Handball Players during a Handball Match
The study was proposed to investigate the changes observed on speed and agility of male handball players during a handball match and it also intend to assess the difference among different playing position. We selected twelve (12) university represented male handball players from Department of Physical Education and Sports Sciences, Annamalai University, Tamilnadu. The selected subjects were classified into three groups with respect to playing position (back court players β 6, wing players β 4 and pivot players β 2). However, in the present study goalkeepers were excluded from the study. The result of the study showed that speed and agility showed no significant difference between first and second half (p > 0.05) during a handball match. However, the ANOVA showed significant difference on speed and agility on first and second half. The ScheffΓ© S post hoc test showed that a significant difference noted between back β pivot (p = 0.006) and wing β pivot (p = 0.010) on speed. Similarly, on agility back β pivot (p = 0.012) and wing β pivot (p = 0.029) but other comparisons displayed no significant difference. It is concluded that 60 minutes of handball match displayed no changes in speed and agility. However, the position wise comparison showed pivot players slow and less agile than other players

Reconstruction of malunited diaphyseal fractures of the forearm
The forearm is a complex anatomical and functional unit with unique osseous, soft tissue and articular relationships. Disruption of these important relations can have a significant impact, leading to pain, instability of the radio-ulnar articulation and reduced range of motion. The gold standard for treating forearm fractures in adults remains anatomic reduction, stable plate fixation and preservation of the surrounding blood supply. Failure to achieve these goals may lead to malunion, requiring reconstructive surgery, which can be technically challenging. In this review, we discuss the essential aspects of anatomy and pathomechanics, clinical and radiological assessment and the state of the art in pre-operative planning and deformity correction surgery

This paper discusses a dual-frequency eddy current testingprocedure developed for inspection of compressor discs of aero engines for detecting fatigue cracks with high sensitivity and reliability. This procedure is capable of detecting fatigue crackssmaller than 2 mm in comparison to 4 mm cracks that can be detected with the currently practiced eddy current testing procedure
Analysis of Selected Hand Anthropometric Measurements among South West Zone Inter University Male Handball Players
The purpose of this study was to analyse the selected hand anthropometric measurements among south zone inter university male handball players. The selected players right and left hand length and width were measured on 144 male handball players who had right hand as dominant hand. These players took part in south west zone inter university handball tournament for the year 2010-2011 organized by S.R.T.M University, Nanded, Maharashtra. In this study date was collected from teams who reached quarter finals and Annamalai University team. The hand length and width was selected as criterion variable and measured by vernier caliper, gulick tape and measuring scale. The collected data was analysed using ANOVA, when F is found to be significant Tukey HSD post hoc test was applied. The result of the study showed that right hand length (F = 1.61, p = 0.126) and left hand length (F = 1.19, p = 0.308) show no significant difference between the groups. However, right hand width (F = 5.450, p = 0.000) and left hand width (F = 6.302, p = 0.000). It shows that Rajasthan university handball players showed greater hand width on both hands than other team players. It can be concluded that hand width shows significant variations among the south west zone inter university handball tournament. The criterion variables which are selected in the present study show significant impact on griping the ball
Socio-economic Impact Assessment of Livelihood Security in Agriculture, Animal Husbandry and Aquaculture on the Tsunami-hit Lands of Andaman
Indian subcontinent is highly vulnerable to major natural disasters such as earthquakes, cyclones, floods, droughts, landslides and bushfires. Tsunami, which is a recent addition to this list, had occurred in the early morning of 26th December 2004, after a massive earthquake of 9.2 magnitude on the Richter scale in Andaman & Nicobar islands, resulting in the submergence of large area of farmland, and subsequent drying up of water bodies. It caused moisture stress for the standing crops, livestock and fisheries and affected the livelihood of the people to a large extent. In this context, the present study has been carried out to make the socio-economic impact assessment of livelihood security in agriculture, animal husbandry and aquaculture on the tsunami-hit lands of Andaman. Data have been collected from 150 sample respondents and the survey has been conducted for two periods, pre-tsunami and post-tsunami. The results have indicated that tsunami has ravaged the households, standing crops, farm inputs such as seed, feed and implements, livestock and poultry population, their sheds, fish ponds, etc., thereby affecting the basic livelihood security of the people in Andaman. The rehabilitation measures taken by the government and NGOs have improved their livelihoods by reviving agriculture considerably in the subsequent years and by creating employment opportunities in various farm and non-farm activities. The paper has suggested creating profitable livelihood security to vulnerable sections of the society in the existing socio-economic penury with holistic intervention of the community, government and NGOs.Agricultural and Food Policy,
Failure Analysis of A 304 SS Girdling Loop of the Boiler in a 500 MW Thermal Power Plant
There were many cases of girdling loop failures in the reheater section of the 500 MW boilers of athermal power station after being in service relatively for a short period of a few months. Within seven months of synchron-ization, the bottom 'U'portion of the front reheater
girdling loop of the boiler of 500 MW thermal power
plant had developed a leak. The plant was restarted
alter replacing the failed protion of the type 304 stain-less steel 'U' tube. Failure occurred again within seven
months of operation. Similar failures followed in the other units of the station
Conformation of phylogenetic relationship of penaeidae shrimp based on Morphometric and Molecular investigations
Understanding of accurate phylogenetic relationship among Penaeidae shrimp is important for academic and fisheries industry. The Morphometric and Randomly Amplified Polymorphic DNA (RAPD) analysis was used to make the phylogenetic relationsip among 13 Penaeidae shrimp. For morphometric analysis forty variables and total lengths of shrimp were measured for each species, and removed the effect of size variation. The size normalized values obtained was subjected to UPGMA (Unweighted Pair-Group Method with Arithmetic Mean) cluster analysis. For RAPD analysis, the four primers showed reliable differentiation between species, and used correlation coefficient between the DNA banding patterns of 13 Penaeidae species to construct UPGMA dendrogram. Phylogenetic relationship from morphometric and molecular analysis for Penaeidae species found to be congruent. We concluded that as the results from morphometry investigations concur with molecular one, phylogenetic relationship obtained for the studied Penaeidae are considered to be reliable.ΠΠΎΠ½ΠΈΠΌΠ°Π½ΠΈΠ΅ ΡΠΎΡΠ½ΡΡ

Age-Acknowledging Reliable Multiplier Design with Adaptive Hold Logic
Digital multipliers are among the most critical arithmetic functional units. The overall performance of these systems depends on the throughput of the multiplier. Meanwhile, the negative bias temperature instability effect occurs when a pMOS transistor is under negative bias (Vgs = βVdd), increasing the threshold voltage of the pMOS transistor, and reducing multiplier speed. A similar phenomenon, positive bias temperature instability, occurs when an nMOS transistor is under positive bias. Both effects degrade transistor speed, and in the long term, the system may fail due to timing violations. Therefore, it is important to design reliable high performance multipliers. In this paper, we propose an aging-aware multiplier design with novel adaptive hold logic (AHL) circuit. The multiplier is able to provide higher throughput through the variable latency and can adjust the AHL circuit to mitigate performance degradation that is due to the aging effect. Moreover, the proposed architecture can be applied to a column- or row-bypassing multiplier. The experimental results show that our proposed architecture with 16 Γ16 and 32 Γ32 column-bypassing multipliers can attain up to 62.88% and 76.28% performance improvement, respectively, compared with 16Γ16 and 32Γ32 fixed-latency column-bypassing multipliers. Furthermore, our proposed architecture with 16 Γ 16 and 32 Γ 32 row-bypassing multipliers can achieve up to 80.17% and 69.40% performance improvement as compared with 16Γ16 and 32 Γ 32 fixed-latency row-bypassing multipliers
