Authors: Gopinath, Rajesh; Jahan Begum, Aftab K. A. Abstract: The Urban Indoor Air Quality is one of the major environmental health concerns in the global scenario, with the indoor pollution levels higher in both private and public indoor spaces than outdoors, in addition to contribution from outdoor sources. As there are about more than hundred Indoor Air Chemical pollutants, the availability of data on exposures, their toxicity levels and associated health risks is extremely variable, thereby making the ranking process highly cumbersome. The situation hence warrants a ranking of indoor chemicals, which is easy to comprehend and adapt as well. In the present study, the research envisages five sequential steps sensitizing priority wise classification to develop the final ranking. The methodology included frequency assessment in terms of source prevalence, frequency of emissions, health impacts, and risk-based concentration versus existing Indoor Air Quality standards and carcinogenicity classification.

S.; Dayananda, H. S. Abstract: Presently, the available means for ascertaining the true potential of organic matter in the form of bio-chemical oxygen demand (BOD5) and chemical oxygen demand (COD) is time consuming and imprecise. To overcome these time based difficulties, an attempt is being made to use a faster mode of assessment by establishing a relationship between BOD and COD with total organic carbon (TOC). To accomplish the same, the domestic wastewater collected from sewage farm, Mysore, sampled over a period of 2 months was analyzed for three parameters, BOD5, COD and TOC. The best fit regression line for BOD5with COD was obtained as BOD5= +0.631 COD mg/L. While the best fit regression line for BOD5with TOC took the form, BOD5= +0.373 TOC mg/L, for COD with TOC, it was COD = +0.565 TOC mg/L. The regression lines so developed, on comparison with practical & graphical values resulted in 99% efficiency.

Authors: Lokesh, Yateen; Kulkarni, Harish J.; Ponnappa, K. Jeffery; Reddy, T. Thejoroop Abstract: he development of transportation plays an important role in the development of nation. With flexible pave-ments being widely used in India, steps must be taken to increase the life of these pavements. Flexible pave-ments are often plagued with problems of cracking and rutting due to repeated traffic loads. Hence one needs to address these prob-lems in order to improve the performance of flexible pavements. This project studies the suitability of coir as a reinforcing material in SDBC grade-2 mix. Marshall Method of mix design was adopted and the optimum bitumen content and fibre content are determined for coir fibre reinforced bituminous mixes and their performance is analyzed. An optimum bitumen content of 5.5%, optimum fibre content of 0.4% and fibre length of 15 mm was obtained after analysis. On studying the parameters, it is found that the addition of coir fibre to SDBC grade-2 mix improves its strength and physical properties.

Authors: Nikhil, T. R.; Kulkarni, Harish J.; Lokesh, Yateen; Prakash, M. R. Abstract: Urbanization has been stemmed as a need to fulfill man’s desire for a better life blessed with the best of facilities that one can afford to be living in. This meant more and more people migrated from their heartlands in the rural environments to the cities and major towns in the country, in search of employment and also a better life. This lead to rapid expansion of Urban Settlements and coupled with “the wave of rising expectations”, his needs kept on multiplying. One of the major aspects that urbanization was witnessed was the rapid explosion in terms of the number of vehicles that have been on the roads in the recent past. As the financial capacities of man increased, more and more people started owning their own vehicles. This phenomenon when taking place in a massive scale leads to problems as congestion and other traffic related issues. India has also seen a similar trend in the rapid growth of traffic in the past two decades. According to the RTOs of the major cities, the vehicle population in the cities have increased manifold, as much as 500 times. Such a massive increase in the vehicle population leads to problems such as frequent traffic snarls, congestion and delays in commute. Intersection or Junction Study was aimed at estimating the current traffic scenario prevailing at the Particular Junction at Mohammeden Block in Malleshwaram, Bangalore City. This is facilitated by means of surveys which are conducted for the junction in consideration. Based on the survey conducted, work is done in analyzing the performance characteristics of the junction with respect to its present capacity, the maximum limits of capacities and also on possible improvements to the traffic situation prevailing in the Junction/ Intersection Fri, 01 Aug 2014 00:00:00 GMT http://13.232.72.61:8080/jspui/handle/123456789/745 2014-08-01T00:00:00Z
