Abstract
This study was aimed to compare the effect of physical and chemical mutagens, namely gamma rays and EMS on seed germination, survival of seedlings and pollen sterility of sesame genotype TMV3. The seeds of sesame variety TMV3 were subjected to different doses of gamma rays such as 10, 20, 30, 40, 50, 60, 70, 80, 90, 100KR and various concentrations of EMS like 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8 and 2.0mM. Seed germination test was carried out in laboratory to find out the LD50 values of Gamma rays and EMS and they were 50KR for gamma rays and 1.0mM for EMS. Based on the LD50 values, the following doses and concentrations were chosen to treat the seeds and conduct the field experiments. For Gamma rays, they were 30, 40, 50, 60 and 70KR and for EMS they were 0.6, 0.8, 1.0, 1.2 and 1.4mM and for Combined treatments they were 30KR+0.6mM, 40KR+0.8mM, 50KR+1.0mM, 60KR+1.2mM and 70KR+1.4mM. The effect of mutagens was measured for quantitative characters like seed germination, seedlings survival, seedlings height and pollen sterility and calculations were made. The results indicated that the seed germination, seedling survival and seedling height were decreased with increasing doses or concentrations of mutagens when compared to control. But in case of pollen sterility, it was increased with increasing concentrations of mutagens when compared to control. In combined treatments, plants showed high percentage of pollen sterility when compared to individual treatments and some plants showed complete sterile at 70KR + 1.4mM treatment.
Comparative Analysis on Physical Fitness Variables of Spin Bowlers and Fast Bowlers in Cricket
Abstract
The purpose of the present study was to compare the Physical Fitness variables of spin bowlers and Fast bowlers in cricket. The study was administered on 40 Cricket players in the age group 16-25 years of participated in the 2012 Buck Cricket Tournament was conducted by YMCA College of physical education, Chennai. The Physical Fitness variable which was used in this study is Flexibility, Agility, Speed, and Balance. To find out the significance difference t-test was used. The level of significance was chosen as 0.05 levels. Result of this study reveals that there was no significant difference exit between the Flexibility (0.362) and significant difference between the Agility (2.041), Speed (2.984) and Balance (2.918) of spin bowlers and Fast bowlers in cricket as the tabulated ‘t’ (2.021).
IN VITRO PRODUCTION OF INDOLE ACIDIC ACID AND BIOACTIVITY OF FUNGAL ENDOPHYTES FROM MEDICINAL PLANTS.
Abstract
Endophytic microorganisms are to be found in almost every plant on earth. These organisms reside in the living tissues of the host plant and do so in a variety of relationships ranging from symbiotic to pathogenic. The aim of the present work was to investigate the fungal endophytes from the medicinal plant Argemone Mexicana.L and Aristolochia baetica.L. The isolate fungal endophytes and might be producing reasonably and pharmaceutically important bioactive (IAA, Enzymes) compounds from these plants. The determine of the antifungal activities of methanol, ethanol chloroform and aqueous extracts of Aristolochia baetica. Leaf against fungi by agar disc diffusion method. The antifungal assay was done against endophytic fungi (Aspergillus niger, Aspergillus flavus, Penicillium sp.). For all the cases it showed significant result.

ESTIMATION OF NUTRIENT CONTENT OF PALMSUGAR AND ITS HYPOGLYCEMIC EFFECT ON SELECTED NIDDM SUBJECTS
Abstract
Study was carried out to assess the hypoglycaemic effect of supplementing palm sugar daily for the period of thirteen days and the long- term effect of palm sugar on twelve NIDDM subjects. The effects of withdrawal of palm sugar in these subjects after a period of fifteen days was also assessed plasma glucose were estimated before and after supplementation and at the end of withdrawal period. Information regarding age, sex, family history of diabetes, dietary pattern and life style details was collected from the subjects using on interview schedule. When the subjects were classified on the familial incident of diabetes, 75% did not have a familial incident of diabetes, whereas, 25% had a familial history of diabetes, 16.6% of the subjects were smokers. It is seen that the mean fasting plasma glucose levels have decreased in the values when compared between the initial and the final day of supplementing palm sugar. After 15 days withdrawal period it is seen that the mean fasting plasma glucose levels have raised from 129.5 on the 31st day to 136.6 at the end of withdrawal period. In the same way the mean postprandial plasma glucose levels have raised from 200 on the 31 st day (end of the supplementation period) to 208. 75 at the end of withdrawal period. The supplementing palm sugar for 30 days have shown a glucose lowering effect and when withdrawn for 15 days the glucose levels have raised to a higher level nearer to that tested on the initial day.
Floral Biology and Seed Development of Swietenia macrophylla King
Abstract
Swietenia macrophylla King – a valuable tropical timber species produce seeds in small quantity with annual variations. Despite of approximately 126-210 flowers per inflorescence, only one to two fruits develop generally. The reasons are not known. We, therefore, had undertaken a detailed study on the structure and development of flowers and fruits and pollination mechanism for the first time. Results showed that mahogany is monoecious with unisexual flowers borne on the same inflorescence in the ratio of 2 male: 1 female. The period between floral initiation and fruit maturity was 8½ months. Flower drop, heavy immature fruit fall within a fortnight after fertilization and the insect, Hypsipyla robusta infestation during early stages of development are the main causes for low seed production in mahogany

EXPERIMENTAL INVESTIGATION ON THE EFFECT OF ALKANE BLENDING ON PERFORMANCE, COMBUSTION AND EMISSION CHARACTERISTICS OF FOUR STROKE DIESEL ENGINE
Abstract
In today’s relevance, it is obligatory to devise the use of diesel in an environmentally benevolent way. So, in this experimental investigation, an attempt was made to increase the combustion efficiency, and thereby to increase the performance and to reduce the exhaust emission by blending an alkane known as n-pentane at 10% by volume with diesel. The performance, combustion and emission characteristics observed while using blended fuels were analyzed and compared with that of diesel as fuel without adding the alkane. The performance analysis reported that, at 80% load, the brake thermal efficiency was increased by 3.684% for the blending of 10% n-pentane with diesel. The maximum heat release rate and peak cylinder pressure were decreased whereas the cumulative heat release was increased for the blended fuel. The emission test concluded that, the smoke density was increased by 0.781% for the blending of 10% n-pentane with diesel. The NOx emission was decreased by 14.634% while using the blended fuel.

Strings of Echoes: A Critical Study on Shashi Tharoor’s Riot
Abstract
Shashi Tharoor made him reflect on Indian ways of life in a close but distant perspective. Riot is a powerful novel – set in and around a riot in India in 1989 — about love, hate, cultural collision, religious fanaticism, the ownership of history, and the impossibility of knowing the truth by the award – winning author of The Great Indian Novel. Riot is a well, researched book with a compelling hard-driving narrative – love, cultural collision, xenophobia, man’s social and political independence are some of its concerns that endeavour to weave history with the illusion of truth and romance, mingling the lives of the different characters caught up in love and communal war, and most of all, in search of their identity. The clash between the private and the public, between one’s individual beliefs and the beliefs of others is thus a confrontation that sometimes results in a riot and this is what the novel emphasizes. A study is made here to study the narrative form, he chronicles, the mystery of Priscilla Hart’s death through the often contradictory accounts of a dozen or more characters, all of whom relate their own versions of the events surrounding her killing. Like his two previous novels, The Great Indian Novel and Show Business, Riot probes and reveals the richness of India. In plot, style and characterization, Shashi Tharoor’s Riot is a brilliant tour de force.
