Climate plays a vital role in the development of any region. Rainfall and temperature are the two important climatic parameters which determine the climatic situation of any place. Pudukkottai is a semi arid District situated in the central part of Tamil Nadu. The study deals with the seasonal and annual variation in rainfall using GIS. Temperature conditions are studied using a simple line graph and the relation between rainfall and temperature are analysised by using ombrothermic diagram.

The Field experiments were conducted to study the influence of off-season land management in combination with various rice weed control measures on the weed competition and yield of rice in two different locations in late samba rice (September 2002 – January 2003) with the rice cultivar of CO 43.

The present paper deals with the analysis of Relative Growth Rate and Doubling Time of conference articles productivity of neural network research at the world and India level. It is found that the conference articles are first in order securing 49.88 per cent (61633) at the world level, whereas in India it holds the second position with 41.88 per cent. The doubling time of publications on neural network research output increased and is at 4.78 years which is more or less double the time of such publications at India level which is 2.89 years.

Length-weight relationship of fish Catla catla and Labeo rohita were studies for six month in Chidambaram area Cuddalore district, India. In the present observation, 80 specimens were collected during January 2010 to June 2010. The relationship between body weights, total length in total specimens were measured maximum and minimum. The body weight varied from Catla catla 113.25 to 1025.82 grams and Labeo rohita 106.81 to 843.17 grams. Total length of Catla catla fishes ranged from 7.47 to 27.04 cm and Labeo rohita 7.07 to 23.21 cm respectively.

This study is an attempt to develop two multidimensional between-group inequality measures by reviewing two multidimensional interpersonal inequality measures. These measures of multidimensional between-group inequality are characterized and applied on Indian data to assess between-group inequality in household monthly per capita consumer expenditure and educational achievement across fourteen major states of India.

Purpose: Telemedicine has emerged as a pivotal innovation in public health, offering new avenues for healthcare delivery and access. This study explores the applications and challenges of telemedicine, emphasizing its impact on public health outcomes. Through a comprehensive literature review and qualitative analysis, we assess the effectiveness of telemedicine in enhancing healthcare accessibility, reducing costs, and addressing the barriers to its widespread adoption.

In the present study Mugil cephalus, Perna viridis and Penaeus monodon was exposed to cadmium, copper, lead and zinc under long term chronic toxicity test to investigate the bioaccumulation pattern of cadmium, copper, lead and zinc to the three marine test organisms. Treated test organisms under long term chronic toxicity test showed that the concentration of heavy metals in the tissues were highly significant (P<0.001) when compared with control. The order of concentration in the tissues of M. cephalus was Zn>Cu>Pb>Cd, P.viridis accumulated in the order of CdZn>Pb>Cd.

In the present investigation, cadmium, copper, lead and zinc induced biochemical changes were studied in post larval stages of Penaeus monodon under long term chronic test (30 days). The total protein content, level of lipid peroxidation, reduced glutathione and the activity of catalase, glutathione S-transferase and acetylcholinesterase in the tissues of Penaeus monodon decreased with the increase in concentrations of heavy metal concentrations used in the long term chronic test for 30 days.

Metals are biologically important. If the threshold concentration of the metal increases in the environment, they may interfere with the metabolic activity of organisms. In the presenting study, an attempt was made to investigate the effect on nickel on oxidative stress and antioxidant enzymes in the liver tissue of Cirrhinus mrigala.

The acute toxicity and bioaccumulation of cadmium, copper, lead and zinc to Penaeus monodon (Tiger prawn) was evaluated in static tests. Each test lasted up to 4 d and LC50 values were also calculated. The toxicity of each metal increased with exposure time for cadmium, copper, lead and zinc. The 96 hours LC50 values for cadmium, copper, lead and zinc were 1.72, 0.66, 0.41, 2.36 mg/l. Lead was toxic metal to P.monodon than zinc followed by cadmium and copper tested. The order of toxicity was Pb>Cu>Cd>Zn.
