Title: Development of attenuators by carbon coating on APBN support rods using RF sputtering techniques Authors: Arya, Suneeta; Sharma, S M; Sharma, R K; Srivastava, V; Bindal, V K; Paul, A K Abstract: There are chances of reflections of unwanted signal, due to several unavoidable reasons, in any working microwave tube. Due to this, the tubes do not give the desired performance. To minimise the chances of reflections the attenuators are used in microwave tubes. These attenuators may be used either inside or outside the tube depending upon its end use. For the fabrication of the attenuators in helix TWTs, the support rods are coated with controlled carbon layer with the specific profile and length using the specific processes. In this paper process of carbon coating on support rods using RF sputtering technique has been described in detail. Page(s): 221-224

Title: Causes of accidents on Yamuna Expressway (Noida to Greater Noida) and suggested remedial measures Authors: Parida, Purnima; Nagar, Harcharan Singh; Chakravarty, Neelima Abstract: The Yamuna Expressway Project is conceived with the idea to not only reduce the travel time between New Delhi and Agra but also to open up avenue for industrial and urban development of the region and provide the base for convergence to tourism and other allied industries. The Government of Uttar Pradesh has been working proactively to improve the connectivity of the National Capital Region (NCR) to improve tourist attraction of Taj Mahal at Agra through the new 6 lanes (extendable to 8 lanes) Access Controlled Expressway with brand name of Yamuna Expressway. The 23.4 km long section of the Yamuna Expressway joins the Noida and Greater Noida. The study stretch starts from Amity University at Noida and ends at Pari Chowk in Greater Noida. The road is 6 lanes divided by approximately 3 m wide median and has 1.5 m paved shoulders. On Yamuna Expressway section joining Noida and Greater Noida, the rate of accidents is much higher than the national average. Degree of fatality is also very high. A study was carried out to identify the reasons for higher accident rate and to explore remedial measures to reduce the accidents. Page(s): 212-220

Title: Correlation among morpho-physiological traits in chickpea genotypes Authors: Singh, Tejpal; Singh, Jasvir Abstract: Correlation coefficients were calculated for different morpho-physiological traits of chickpea with biological yield and seed yield under different environments. The biological yield had positive correlation with number of primary branches, relative water content (RWC), crop growth rate (CGR), net assimilation rate (NAR), seed yield and heat use efficiency and negative correlation with membrane injury index (MII) and days to different phenophases. Seed yield had positive correlation with leaf area index (LAI), total chlorophyll content, CGR, number of seeds per pods, biological yield, harvest index and heat use efficiency and negative correlation with MII, protein content and days to different phenophases.

Title: Provision of sustainable road transport infrastructure : A case study of urban corridor in Delhi Authors: Shekhar, Ch Ravi; Gupta, Kamini; Kumar, Ravinder; Kankdurai, B Abstract: Indian economy is rapidly growing and along with it the travel demand is also increasing exponentially. The number of motor vehicles in India which were around half a million in the year 1950 has now increased to more than 60 million. This increased motorization, urbanization, population growth lead to traffic congestion, which can be particularly seen on many urban arterial roads. Congestion reduces utilization of the transportation infrastructure and increases travel time, fuel consumption, air pollution and traffic accidents etc. The existing congestion measure depends on average travel time, unable to quantify the performance of the transportation system in terms of sustainability. Therefore, there is a need to investigate performance measures to evaluate Sustainable Transportation System. Sustainable transportation attempts to estimate travel time reliability, economic development, environmental and social equity of current and future generations. The objective of this study is to evaluate sustainability of system by considering the delays in travel time and driving cycle patterns. Travel time based performance measures are considered to evaluate performance of sustainability of transportation system. In this study an urban arterial corridor of 4km long on National Highway No. 2 of Delhi Mathura road has been considered and videographic data in morning peak hours was collected for estimating travel time through license plate matching technique and driving cycle through V box. The benefits in terms of social, economical and environmental terms are studied and computed by providing suitable infrastructure facilities. Page(s): 196-205
