Basically teaching must include two major components sending and receiving information. Ultimately a teacher tries his best to impart knowledge as the way he understood it. The purpose of the education is not only to make the students literate but also to make them creative, knowledgeable, think of their own and to meet the workforce. The success of a student depends on the teacher and the innovative methods which they incorporate in teaching. The use of innovative methods in educational institutions has potential not only to improve education but also to empower people, strengthen governance and galvanize the effort to achieve the human development goal for the country

Gastric ulcer was artificially induced in the albino rats by administering aspirin and antiulcer activity of the selected vegetables was evaluated by assessing the free acidity, total acidity, ulcer index and histoarchitecture of the stomach. Ethanol extract and fresh juice of carrot significantly decreased the free acid level and total acid output in aspirin induced ulcer rats. Similarly, fresh juice and ethanolic extract of radish remarkably decreased the free acid level and total acid output in aspirin induced ulcer rat model. Ulcer score was comparatively found to be low in the ethanol extract of carrot and radish treated rats. The percentage of curation index was observed to be high in the radish treated rats and in the carrot extract treated rats as well. Further the histological studies also supported by these results and they recovered the cellular damage caused by aspirin. From the results, it is concluded that both the radish and carrot have antiulcer activity and thus it may be recommended for the treatment of gastritis and gastric ulcer in alcohol abuse patients.

Availability of irrigation water at reasonable cost is one of the most important factors for agricultural development. Conjunctive use of fresh and grey water can successfully be adopted for cultivation. The waste water was collected from the Sir. CVR ladies hostel, Nehru Memorial College, Puthanampatti. An experiment was laid out at the research plot of Nehru Memorial College, Puthanampatti, Tiruchirappalli. The collected samples were subjected to systemic analysis of the below stated physiochemical parameters and biological testing. The tested physiochemical parameters are pH, Dissolved oxygen (DS), Total Dissolved Solids (TDS), Salinity and conductivity. Treated waste water samples were serially diluted and microbial analysis was done for identify the bacterial colonies. It was observed that the higher level of vegetative yield of radish crop and provides maximum return at 100% sewage water. Plant height, root length and girth significantly increased with the increase of sewage content in the grey water. The crop production using waste water favourably altered the physicochemical parameters of the soil and water. The present study shows the good yield and water use efficiency of radish (Raphanus Sativus) crop increase with an increase in grey water.

Despite the widespread use, there is a lack of scientific evidence on their efficacy and safety. The present study was undertaken to know the toxic effect of the aqueous extract of antidiabetic polyherbal formulation (includes Andrographis paniculata, Andrographis alata, Adhatoda zeylanica, Gymnema sylvestre, Syzygium cumini and Justicia glabra) on albino rats. Toxic effect of aqueous extract of antidiabetic polyherbal formulations on male albino rats were investigated by administering at a daily doses of 10mg/kg b.wt., 100mg/kg b.wt. and 1000mg/kg b.wt. for 30 days. Mortality of the rats due to toxic effect if any and abnormal behaviour was noted. Biochemical parameters such as SGOT, SGPT, ALP, ACP, Urea, Uric acid, Creatinine and Bilirubin were measured as indices or organ specific toxicity or potential drug interactions. Toxicity studies revealed the non-toxic nature of aqueous extract of antidiabetic polyherbal formulations. No mortality was observed in aqueous extract of antidiabetic polyherbal formulations treated rats. Similarly, no abnormal behaviours were observed in experimental rats and they also appeared in normal condition. Further, this herbal formulation did not affect any biochemical parameters under the study. Thus the polyherbal formulation may be used for the treatment of diabetes mellitus.

The anti-diabetic effect of polyherbal drug was evaluated by test hypoglycemic activity and antioxidant activity. To determine the antioxidant effects of polyherbal drug, hepatic and renal antioxidant markers such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH), and lipid peroxidase (LPO) were studied. Type 2 diabetes had a significant impact on these indicators, but oral administration of the polyherbal drug significantly improved them. The results indicated that there were no significant changes in hypoglycemic activity of various extracts of polyherbal medication treated rats at varied dosages, and it was determined to be within the normal range. The antioxidant activity of polyherbal drug extracts in aqueous, ethanol, ethylacetate, and chloroform extracts in STZ-treated rats indicated that the level of antioxidant enzymes was acceptable.

Transmission Control Protocol (TCP) is one of the prominent protocol that contributes a considerable amount of internet traffic as the vast majority of internet applications such as file transfer, messaging service, mail services, etc. was based on TCP. However, TCP performs poorly under vehicular wireless environment due to its high mobility and wireless errors such as fading and interferences that lead to unpredicted packet drop. In this paper the behavioral aspects of existing standard TCP variants such as Vegas, Compound , Westwood, New Reno, BIC and CUBIC were rigorously tested and analyzed under vehicular environment for variable speed and traffic. This analysis forms a foundation work in designing TCP exclusively for vehicular environment.
