In the present investigation binding energy of the laser dressed hydrogenic donor in a Semi magnetic Quantum Wire like Cd1 – xMnx2Te/Cd1 – x1Mnx1Te/Cd1 – x2Mnx2Te and spin polaronic shift has been computed for various magnetic and laser fields within the effective mass approximation in the finite barrier model using variational method. The results are presented and discussed. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/2790

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 – 6, wing players – 4 and pivot players – 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 Scheffé S post hoc test showed that a significant difference noted between back – pivot (p = 0.006) and wing – pivot (p = 0.010) on speed. Similarly, on agility back – pivot (p = 0.012) and wing – 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

Magnetic properties of Hydrogenated Li and Co doped ZnO nanoparticles

The effect of hydrogenation on magnetic properties of Zn0.85Co0.05Li0.10O nanoparticles is presented. It was found that the sample hydrided at room temperature (RT) showed weak ferromagnetism (FM) while that hydrided at 400oC showed robust ferromagnetism at room temperature. In both cases reheating the sample at 400oC in air converts it back into paramagnetic state (P) completely. The characterization of samples by X-ray and electron diffraction (ED) showed that room temperature ferromagnetism observed in the samples hydrogenated at RT is intrinsic in nature whereas that observed in the samples hydrogenated at 400oC is partly due to the cobalt metal clusters.Comment: 10 pages, 3 figure

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

Single crystal diamond nanobeam waveguide optomechanics

Optomechanical devices sensitively transduce and actuate motion of nanomechanical structures using light. Single--crystal diamond promises to improve the performance of optomechanical devices, while also providing opportunities to interface nanomechanics with diamond color center spins and related quantum technologies. Here we demonstrate dissipative waveguide--optomechanical coupling exceeding 35 GHz/nm to diamond nanobeams supporting both optical waveguide modes and mechanical resonances, and use this optomechanical coupling to measure nanobeam displacement with a sensitivity of $9.5$ fm/$\sqrt{\text{Hz}}$ and optical bandwidth $>150$nm. The nanobeams are fabricated from bulk optical grade single--crystal diamond using a scalable undercut etching process, and support mechanical resonances with quality factor $2.5 \times 10^5$ at room temperature, and $7.2 \times 10^5$ in cryogenic conditions (5K). Mechanical self--oscillations, resulting from interplay between photothermal and optomechanical effects, are observed with amplitude exceeding 200 nm for sub-$\mu$W absorbed optical power, demonstrating the potential for optomechanical excitation and manipulation of diamond nanomechanical structures.Comment: Minor changes.

Towards an Institutional Knowledge Repository (IKR) at IGCAR

The collective acquired information of an organization is called the ‘institutional knowledge’. The centralized Knowledge Repository uses standard taxonomies to consolidate information into one place allowing knowledge to be searched and retrieved with maximum efficiency and accuracy. Many organizations have realized the value of institutional knowledge and already initiated knowledge management systems that collect, store, redistribute, utilize and ultimately leverage the institutional knowledge for the benefit of the organization. All the organizations, in particular the R&D institutions like IGCAR need to build knowledge repository on its specific areas of interest. Once created, the IKR will act as a vehicle for knowledge dissemination, sharing and transfer. This paper gives a comprehensive view on building IKR at IGCAR

User interface design and development: the role of open source systems

Open Source movement has tremendously influenced Information industry, in particular the Digital Library Environment where the Information Systems and services are inevitable. This has helped the Library and Information Centers in developing User Interface to render web based services to the patrons. Wherever the network infrastructure and the target users are in place, the design and development of IR user interface using Open Source system for a specific application is very much possible. This paper highlights the role of Open Source Systems in detail and explains a prototype IR User Interface which was developed in-house at Indira Gandhi Centre for Atomic Research, Kalpakkam
