Algae are important food sources for aquatic insects including mosquitoes. Eight mosquito species were collected in and around Mysore city in order to examine the gut contents of the larvae. A total of sixty five species of algae were identified from different larval habitats of mosquito larvae, out of which 55 were encountered in the larval guts. From these algal species identified in the larval gut, 21 (38.18%) belonged to Bacillariophyceae, 12 (21.8%) to Chlorophyceae, 9 (16.36%) to Cyanophyceae, 7 (12.72%) to Desmidaceae and 6 (10.9%) to Euglenophyceae. From the larval breeding sources, out of the 65 identified species, 26 (40%) belonged to Bacillariophyceae, 16 (24.6%) to Chlorophyceae, 10 (15.3%) to Cyanophyceae, 7 (10.76%) to Desmidaceae and 6 (9.2%) to Euglenophyceae. Identification of food sources and their importance to larval development and survival is particularly relevant to the development of novel vector control methods, especially in the study area where malaria, chikungunya and dengue are endemic.

Hybridmaize (MHM9001) seeds were treated with varied concentrations of Tricyclazole, a systemic fungicide used to control blast disease of rice. Themain composition of Tricyclazole is 70% sodium lauryl sulphate. It is used for both seed treatment and foliar spray. Morphological and biochemical parameters were analysed. Multiple sets were prepared for comparison with untreated sets.All parameters wereanalysed using standard methods and the results were subjected to 2 tailed " t" test and Pearson's Correlation Matrix and also Bray- Curtis similarity index. The tables were analysed to know the effect of Tricyclazole on cultivar of maize. A strong positive correlation exists between Vigour index and DNA purity in the samples treated with the fungicides, and a negative correlation between root length and fresh weight of the samples. 94% similarity was seen between chlorophyll-a and chlorophyll-b; and shoot length and fresh weight when Bray-Curtis similarity index was applied.

Air Quality Index (AQI) in seven prime localities of Mysore city was determined using the U.S.EPA AQI calculator. Index values for Particulate Matter (PM) at Manasagangotri campus and Ramaswamy Circle are categorized as unhealthy and residents in these surroundings are advised to avoid prolonged exertion. PM index at Fountain Circle and KIDB area are quite high and categorized as very unhealthy. Five Light Circle, K R Circle and Nehru Circle have highest PM indices and are categorized as hazardous. Index values for sulphur dioxide and nitrogen dioxide are below the standards prescribed in these areas. At some places they appear to be slightly high and people with asthma or other respiratory diseases, elderly persons and children are at risk. Use of electrostatic precipitation at industry levels and diesel particulate filters at vehicle levels may reduce the PM values. Alternate fuel may be another means of reducing particulate matter.

Microbes in freshwater often change the water quality and render it unfit for public use. Many methods of water quality determination have been discussed. A Simple but useful index is the National Sanitation Foundation-Water Quality Index (NSF-WQI). This index can be calculated by determining only nine physicochemical parameters. Water temperature, pH, dissolved oxygen, biochemical oxygen demand, total phosphorus, nitrates, total suspended solids, turbidity and faecal coliforms were used for the calculation of the index. The water quality of the pond was found to be medium. Source

The Freeze-Tag Problem is a scenario in which there is "n" number of robots; n-1 ones are "asleep" and one is "awake". Any awake robot can move and awaken another robot by touching it. The woken up robot can wake up other robots. The optimal goal is to minimize the required time to awaken all the sleeping robots. We present a simulated annealing approximation which improves an existing solution and runs in a short period of time. © 2011 IEEE. Source
