Effect of laser on the bound magnetic polaron in a semimagnetic quantum wire
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.

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
fm/ and optical bandwidth 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
at room temperature, and in cryogenic
conditions (5K). Mechanical self--oscillations, resulting from interplay
between photothermal and optomechanical effects, are observed with amplitude
exceeding 200 nm for sub-W absorbed optical power, demonstrating the
potential for optomechanical excitation and manipulation of diamond
nanomechanical structures.Comment: Minor changes. Corrected error in units of applied stress in Fig. 1
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
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
