Abstract: this study was aimed to evaluate and compare the pathogenicity of rabies virus isolated from bats and dogs, and to verify the efficacy of a commercial rabies vaccine against these isolates. for evaluation of pathogenicity, mice were inoculated by the intramuscular route (im) with 500micld50/0.03ml of the viruses. the cross-protection test was performed by vaccinating groups of mice by the subcutaneous route and challenged through the intracerebral (ic) route. isolates were fully pathogenic when inoculated by the ic route. when inoculated intramuscularly, the pathogenicity observed showed different death rates: 60.0% for the desmodus rotundus isolate; 50.0% for dog and nyctinomops laticaudatus isolates; 40.0% for artibeus lituratus isolate; 9.5% molossus molossus isolate; and 5.2% for the eptesicus furinalis isolate. mice receiving two doses of the vaccine and challenged by the ic route with the isolates were fully protected. mice receiving only one dose of vaccine were partially protected against the dog isolate. the isolates from bats were pathogenic by the ic route in mice. however, when inoculated through the intramuscular route, the same isolates were found with different degrees of pathogenicity. the results of this work suggest that a commercial vaccine protects mice from infection with bat rabies virus isolates, in addition to a canine rabies virus isolate.

Abstract: The continuous rise in the number of suicides among Indian rural based farmers is not solely due to lack of funds or failure of crops or huge amount of interests on debts. Many a time the farmers are in daze triggered by the panic and fear both of which are due to lack of information backed by appropriate technologies. Lack of information about the appropriate crop patterns the farmers should choose depending on the market demands and remunerative prices, availability of water, supply of seeds for sowing, proper knowledge of the use of manures and ways to avoid over use of pesticides--did contribute to the ever increasing number of suicides in the regions of Vidharbha and Andhra Pradesh, Karnataka and Tamil Nadu. The Government machinery comprising Agricultural extension officers, backed by the Agricultural programs on Radio and TV could hardly meet the information required for these farmers affected with the compounding problems. Use of convergent mobile technologies with the internet and e-mail facilities is the need of the hour. The latest data drawn from the IMRB survey (The I-Cube 2007) indicated that internet usage in India has grown by more than 11 times over the last seven years. The internet expansion is seen moving down from the metros to towns with population less than half a million with the number of users up by 69 times since 2007. In the last two years, 2005 and 2006, on an average 4.5 million new mobile subscribers were added every month. Convergent mobile technologies with wide range of mobiles and packages being available now hold the promise of offering basic literacy and numeracy skills accessible to the small farmers in India, besides a lot of information concerning the availability of loans at lower interest through banks and self-help groups, crop patterns, remunerative prices for the produce, export norms for the crops, e-marketing and e-commerce, etc, The paper outlines a visualization of such an optimistic design of use of convergent mobile technologies.

Abstract: antibodies to enterovirus 71 (ev71) were evaluated in s?o paulo state during 1999-2005. the titer of neutralizing antibodies against ev71 was determined by microneutralization assay, and a titer of > 1:8 was defined as indicative of protected immunity. neutralizing antibodies to ev71 were observed in 12.4% (55/442) of sera samples, a low protective rate, suggesting that ev71 infection is uncommon in this region, but that there is a relatively high susceptibility to ev71 related diseases, which is worrying considering the recent asian outbreaks. also, a significant location-specific difference in seropositivity was observed. neutralizing antibodies to ev71 were observed in 8.7% (21/241) of s?o paulo metropolitan area sera samples, and 16.9% (34/201) of the sera samples from other municipalities. a high number of brazilian residents live in country and coastal areas without adequate access to piped water or sanitation. this situation may contribute to the ev71 dissemination in these zones. the analysis of environmental samples could possibly make a valuable contribution to studies on the epidemiology of ev71.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.106037
Abstract: Aluminum based composites are very popular in automotive and aerospace segments. In particular aluminum alloy-SiC composite systems are widely studied and seriously explored for various other applications in defense and space. However they have not been looked at as potential materials in naval and chemical applications where synergistic effects of both wear and corrosion need to be addressed to. This needs the assessment of wear behavior of composites. From the survey, it is evident that major focus is on mechanical and corrosion properties of cast composites. However, meager information is available as regards the slurry erosive wear behavior of cast and extruded metal matrix composites. In the light of the above, the present investigation is aimed at studying in detail the slurry erosive wear behavior of cast and hot extruded Al6061 and Al6061-SiC composites in sand slurry. Al6061-SiC composites have been prepared primarily by vortex method. Hot extrusion of these composites and the matrix alloy has been carried out at 550℃ using a 500T hydraulic press. Both as cast and hot extruded composites have been subjected to microstructure studies, microhardness, and slurry erosive wear tests. The hot extruded composites exhibit higher hardness, and slurry erosive wear resistance when compared with as cast alloy and its composites.
