The aim of the study was to assess the effect of temperature on the occurrence of desmids on a lentic waterbody viz. Jawahar Bal Udhyan Pond situated in northern direction of the Bhopal district with reference to its seasonal variation in physico-chemical parameters. Water temperature of the lentic water body varied between 16.2°C to 31.9°C in winter and summer season respectively. During the present study period a total of 18 desmid taxa of 6 genera were encountered in which Cosmarium dominated in terms of species diversity. Desmids occurred maximum in winter season i.e., from December to February and minimum in post monsoon season i.e., from October and November. Different species of Closterium, Euastrum, Staurastrum, Pleurotaenium, and Sphaerozosma are considered as pollution tolerant species and the presence of all these species and result of physico-chemical parameters indicates the meso-eutrophic condition of the waterbody.

The present investigation deals with the prevalence of three cestode parasites viz. Lytocestus sp., Proteocephalus sp. and Gangesia sp. collected from the intestine of a freshwater fish Channa punctatus in different blocks of Meerut region (U.P.) India during June, 2014 to May, 2015. A total of 125 parasites were collected throughout theyear. The high incidence of infection of all these species Lytocestus sp., Proteocephalus sp., Gangesia sp. was recorded in summer season (70.83%, 77.27% abd 72 % respectively) followed by winter season (63.63%, 57.89% abd 52.38% respectively) whereas infection was low in monsoon season (36.84%, 27.78% abd 23.52% respectively). The present study clearly indicates that the intensity of infection throughout the year was found highest in summer season followed by winter and lowest in monsoon. Findings show that beginning of the breeding period, feeding habitat, presence of intermediate host and environmental factors are influencing the seasonality of cestode parasitic infection.

Abstract Objective: The study objective was to estimate trachoma prevalence in relation to seasonal variation among children. Methods: Study Design was cross sectional and data was collected during all seasons of the year. After randomization of population units, 10% of them were identified by lottery and 5% of them were selected and examined for active trachoma case detection by simple random sampling technique. Total number of study participants were nine thousands seven hundred and ten (n=9710) from both urban and rural population units. The study was conducted during January –December 2018 during all three seasons of the year. After clinical examination, data was entered into a questionnaire Performa, which was used as tool for data collection. A Chi-square test was applied to compare trachoma cases among different seasons and among both boys and girls. Results: Maximum burden of disease (62.4%) was reported during spring and winter season. Both spring and winter seasons have six months duration. During summer season, 37.6% (n=70) cases were reported. A highly significant (<0.01) relationship was reported between summer and spring seasons and trachoma prevalence (p < 0.01). A high prevalence was noted among female children. Conclusion: Higher prevalence of active trachoma was noted during summer season. Keywords: trachoma, seasonal variation, children, Continuous...

AbstractJatropha curcas L. is a stem-succulent shrub that produces high concentrations of seed oils that are convertible into biodiesel. In this study, the incidence of four insect pests on Jatropha, Strabala rufa, Gnathamitermes tubiformans, Pempelia morosalis, and Acanthoplus discoidalis was recorded over three years in a semi-arid climate in Gaborone, Botswana. The occurrence of these insects was concentrated in the summer season from October to April, while lower numbers of all species were found in May as the temperature began to reduce towards the winter season, suggesting that insect pests of Jatropha exhibit a unique temporal pattern in this region. A considerable variation was observed among Jatropha accessions regarding the insect pest occurrence, indicating a vast difference in the susceptibility to insect pests among Jatropha accessions.

Introduction: In western regions of Nepal many more cataract operations are performed during the winter season than the summer season. This causes problems with resource allocation. The aim of this study was to assess the magnitude of seasonal variation in cataract surgery, explore the causes, and make recommendations to optimize resource utilization.Methods: Hospital data of the number of patients undergoing cataract surgery in the years 2011, 2012 and 2013 in 3 hospitals was analyzed by month of surgery. 100 consecutive patients having cataract surgery in the winter season and 100 in the summer season were compared for differences and questioned as to the reasons for choosing cataract surgery at that time.Results: Of the 127,718 cataract operations performed over 3 years in the 3 hospitals, 45% were performed in the 3 months February-April and 9% in the 3 months June-August. The mean number performed in March (highest volume month) was more than 7 times higher than that performed in July (lowest month) – 8016 versus 1041 per month. At univariate level nationality, marital status, socioeconomic status, cost per surgery, occupation, age and ethnicity were associated with seasonal variations. Multivariate logistic regression analysis of seasonal uptake showed Nationality/Ethnicity, Socioeconomic status and cost per surgery statistically significant in predicting attendance in high season.Conclusions: There is a large seasonal variation in cataract surgery numbers in West Nepal. Factors including patients' nationality cost of surgery and cultural beliefs contribute to the seasonal variation. If these can be addressed then resource allocation and utilization can be improved.JNGMC Vol. 12 No. 2 December 2014, Page: 24-29

Statistical analysis was carried out between seasonal milk yield and some of the derived climatic variables at a semi-arid tropical locality in Bangalore. The study revealed that the milk yields varied from the highest (9, 3 lit/cow/day) in summer season to the lowest (8, 5 lit/cow/day) in winter season and almost the same in both the monsoon season (8, 7 and 8, 5 lit/cow/day during southwest and northeast monsoon seasons). It was envisaged that the climatic components like wind chill index had negative effect while wetness index and photo-thermal heat units had both positive (summer and winter seasons) and negative (two monsoon seasons) influences on seasonal milk yields.
