Quantum differential operators on the quantum plane
The universal enveloping algebra U(g) of a Lie algebra g acts on its
representation ring R through D(R), the ring of differential operators on R. A
quantised universal enveloping algebra (or "quantum group") is a deformation of
a universal enveloping algebra and acts not through the differential operators
of its representation ring but through the quantised differential operators of
its representation ring. We present this situation for the quantum group of

Poverty and its Alleviation Lessons for Nigeria
The study focused on the persistent poverty status in Nigeria in spite of all the actions and activities directly and indirectly put in place to reduce it. Nigerian poverty statistics and government actions in tackling poverty were examined. Few countries that have succeeded in reducing poverty position were briefly examined. Specifically, we highlighted how Malaysia, China and South Korea aspired and attained high level poverty alleviation. The lessons of their success stories were the basis for recommendations for Nigeria as a panacea for poverty reduction which has persevere in spite of every efforts over the years. Among the recommendations made include designing of poverty line for the entire geopolitical zone, stating target of poverty reduction within a time frame, and sincerely implementing and monitoring of strategies, programmes and policies.

Examination Malpractice in Nigeria: Causes and Effects on
Education, being a process of teaching and learning is evaluated through examination at the end of the learning period. Examination not only serves as a feedback for the trainer to ascertain the level of knowledge acquisition but also serves as a measure of knowledge retention by the trainee. Any misconduct or irregularity distorts this feedback mechanism and gives a false outcome of the learning process. This paper examines the causes and forms of examination malpractice in Nigeria, the consequences on the national development, previous efforts made at curbing it and recommended ways of eradicating examination malpractice in the country. Relevant journals and conference papers consulted, and the writers’ personal experiences during examination invigilation were the sources of data used in the paper. It is discovered that the perennial lack of political will on the part of government to enforce the Decree 20 of 1984 and now, Examination Malpractice Act 33 of 1999 has caused the examination misconduct to remain on the increase in Nigeria. This paper recommends strongly that the Examination Malpractice Act of 1999 should be amended to incorporate that section of Decree 20 of 1984 which stipulated twenty-one years imprisonment without option of a fine for a convicted culprit. And the Act should be diligently enforced no matter whose ox is gored. Keywords: Education, Examination Malpractice, Institutions, National Developmen

Managing Sports State Anxiety with Yoga among Athletes – A Probe into Facts
The Purpose of the study was to find out, the intervened effect of yoga on State Anxiety among the peak performers of athletics. The subjects chosen for the study were 30 athletes of different genres from University of Madras, Chennai. Their age ranged between 20 and 25 years. They were randomly divided into two groups of 15 each, one being the experimental group and the other a control group. The experimental group underwent a scheduled yoga practice for a period of 8 weeks, 6 days/week as the control group was on daily regular routine. The status of State Anxiety was measured before (Pre-test) and after (Post-test) the experimental period using Manual of Statetrait Inventory developed by Spielberger (1970). The data were analyzed statistically for significant differences. Later applying analysis of variance and analysis of co-variance (in case of insignificance), significance in variance is shown, and further Scheffe?s test was applied. The result proves that the yogic scheduled practices have made a significant impact on the State Anxiety of the experimental group compared to the control group
Angular Resolution of an EAS Array for Gamma Ray Astronomy at Energies Greater Than 5 x 10 (13) Ev
A 24 detector extensive air shower array is being operated at Ootacamund (2300 m altitude, 11.4 deg N latitude) in southern India for a study of arrival directions of showers of energies greater than 5 x 10 to the 13th power eV. Various configurations of the array of detectors have been used to estimate the accuracy in determination of arrival angle of showers with such an array. These studies show that it is possible to achieve an angular resolution of better than 2 deg with the Ooty array for search for point sources of Cosmic gamma rays at energies above 5 x 10 to the 13th power eV
Radial flow of kaon mesons in heavy ion reactions
This work investigates the collective motion of kaons in heavy ion reactions
at SIS energies (about 1-2 GeV/nucleon). A radial collective flow of
mesons is predicted to exist in central Au + Au collisions, which manifests in
a characteristic "shoulder-arm" shape of the transverse mass spectrum of the
midrapidity mesons. The radial flow arises from the repulsive
mean field in nuclear matter. In spite of a strong reabsorption and
rescattering the attractive mean field leads as well to a collective
radial flow of mesons. The radial flow, however, is different from
that of mesons and can be observed by a characteristic "concave"
structure of the transverse mass spectrum of the mesons emitted at
midrapidity. The kaon radial flows can therefore serve as a novel tool for the
investigation of kaon properties in dense nuclear matter.Comment: 30 pages RevTex, 5 PS figures, accepted for publication in Phys. Rev.
Drift gill net fishery along Mangalore-Malpe coast
Drift gill net is the major gear used in Mangalore- Malpe area to catch large pelagic fishes. Though the catch by drift-gill net forms only 1% of the toala marine fish catch, the value of the quality fishes it lands exceeds the value of other gears. this gear plays a pivotal roal in the economy of indigenious fisheries sector. the article deals with operation details of drift gill net, catch composition of major fishes and economic status of fishes due to this drift gill net
Measuring visual cortical oxygenation in diabetes using functional near-infrared spectroscopy
Aims: Diabetes mellitus affects about 6% of the world’s population, and the chronic complications of the disease may result in macro- and micro-vascular changes. The purpose of the current study was to shed light on visual cortical oxygenation in diabetic individuals. We then aimed to compare the haemodynamic response (HDR) to visual stimulation with glycaemic control, given the likelihood of diabetic individuals suffering from such macro- and micro-vascular insult.
Methodology: Thirty participants took part in this explorative study, fifteen of whom had diabetes and fifteen of whom were non-diabetic controls. The HDR, measured as concentrations of oxyhaemoglobin [HbO] and deoxyhaemoglobin [HbR], to visual stimulation was recorded over the primary visual cortex (V1) using a dual-channel oximeter. The stimulus comprised a pattern-reversal checkerboard presented in a block design. Participants’ mean glycated haemoglobin (HbA1c) level (±SD) was 7.2±0.6% in the diabetic group and 5.5±0.4% in the non-diabetic group. Raw haemodynamic data were normalised to baseline, and the last 15 s of data from each ‘stimulus on’ and ‘stimulus off’ condition were averaged over seven duty cycles for each participant.
Results: There were statistically significant differences in ∆[HbO] and ∆[HbR] to visual stimulation between diabetic and non-diabetic groups (p<0.05). In the diabetic group, individuals with type 1 diabetes displayed an increased [HbO] (p<0.01) and decreased [HbR] (p<0.05) compared to their type 2 counterparts. There was also a linear relationship between both ∆[HbO] and ∆[HbR] as a function of HbA1c level (p<0.0005).
Conclusions: Our findings suggest that fNIRS can be used as a quantitative measure of cortical oxygenation in diabetes. Diabetic individuals have a larger HDR to visual stimulation compared to non-diabetic individuals. This increase in ∆[HbO] and decrease in ∆[HbR] appears to be correlated with HbA1c level
