OBJECTIVES Aedes mosquitoes are responsible for transmitting the dengue virus. The mosquito lifecycle is known to be influenced by temperature, rainfall, and relative humidity. This retrospective study was planned to investigate whether climatic factors could be used to predict the occurrence of dengue in East Delhi. METHODS The number of monthly dengue cases reported over 19 years was obtain...

The investigation on the reproductive life of Indian Mackerel, Rastrelliger kanagurta (Cuvier 1817) in Uttara Kannada coast for a period 13 months was performed from Jan 2018 to 2019. A total 1299 fishes were dissected entire and their biological parameters investigated. Of these fishes, 734 female, 435 male 130 indeterminate. Throughout year fishery present with copiousness pre-monsoon post-mo...

Abstract The spatial and temporal variations in the hydrochemistry of Sutlej river Indian Punjab were studied based on water quality parameters analysed during pre- post-monsoon seasons years 2017 2018. grab samples collected from using stratified random sampling for pH, electrical conductivity (EC), carbonate (CO 3 −2 ), bicarbonate (HCO − chloride (Cl nitrate (NO total hardness, calcium (Ca +...

The present study was conducted during the year 2018-2019 to determine impact of road on Air Pollution Tolerance Index (APTI) plants growing along road. A comparative done between three roads viz., National highway, State highway and Link Road. Among roads, link can be considered as control because vehicular emissions were minimal or non-existent. Three (Dalbergia sisso, Mangifera indica Ficus ...

AIM To determine the possibility of leptospirosis among patients from urban slums presenting with febrile illness during monsoon and post-monsoon season. METHODS Evidence of leptospirosis in 180 patients with febrile illness was determined by looking for presence of immunoglobulin M (IgM) antibodies by leptospiral IgM enzyme linked immunosorbent assay (ELISA). The test was carried out on 160 ...

Seasonal variation on physico-chemical quality of well water at Eloor industrial area, Kerala was studied. A total of 100 samples, 25 each during four different seasons, viz. summer, premonsoon, monsoon and post monsoon were collected during the year 2009 and analyzed for temperature, pH, total hardness, Chemical Oxygen Demand, concentration of nitrate, fluoride, iron, heavy metals like lead, m...

Attempts were made to study temporal variation in monthly, seasonal and annual rainfall over Kerala, India, during the period from 1871 to 2005. Longterm changes in rainfall determined by Man-Kendall rank statistics and linear trend. The analysis revealed significant decrease in southwest monsoon rainfall while increase in post-monsoon season over the State of Kerala which is popularly known as...
