Bio-Energy Generation: A Sustainable Environmental Technology for Waste Management

Abstract: -The paper reports prototype system has been developed, which is suitable for waste management. In Indian context Hostel & hotel industries increased vigorously during last two decades in most of the urban centers in India. The survey of some hostels, hotels showed that various kinds of solid wastes get generated and disposed off in nearby area without caring for any kind of treatment. These wastes can be grouped as Dry waste & Wet Waste. Amongst the various methodologies used for treating solid waste the reuse and / recycling methodology for dry waste whereas Biogas method for treatment of wet biodegradable solid waste found to be most suitable, feasible and economically viable method; It is eco friendly and purely natural process. The entire quantity of solid waste will get converted into biogas and NPK-rich organic manure. The process is very simple and. does not require highly technical personnel to operate it even to run in mega scale plants. The process is anaerobic decomposition of organic matter by a group of micro flora to produce biogas. It is alternative fuel for cooking, which will reduce the demand for fossil fuel. In this paper an Environmental Sound Technology (EST), pertaining to its experimental model with integration of various bio-systems discussed & a typical 25 cum Biogas digester is being design. Enhancing ecological literacy for waste material segregation at source

Ichthyofaunal diversity in Bachan Gad and Kakda streams of the Mid-himalayan Ganga river system of Garhwal in relation to stream gradient and distance

The present study was carried out to investigate the comparative seasonal distribution and relative abundance of fish fauna of streams Bachan Gad of river Alaknanda and Kakda Gad of river Mandakini of Mid-himalayan Ganga river System. Total length of the Bachan Gad is 14.5 km from origin to the confluence at main river Alaknanda with an altitudinal variation from 605.94 to 1418.23m (a.s.1), whereas, total length of the Kakda Gad is 15.5 km. from origin to confluence at main river Mandakini with altitudinal variation from 984.50 to 1993.70 m (a.s.1). Total 23 species from Bachan Gad and 20 fish species were identified from Kakda Gad. The differences in the availability of fish-fauna were directly related to the nature of the profile and slope of tributaries; which affects the migration and breeding grounds of the fishes inhabited in the main river Alaknanda and Mandakini of Ganga river system. Variation in the availability of fishes has been recorded from different sites of the stream. In streams and rivers the changes take place along their length is directly related to the eco-physico-chemical nature (water depth, current, substratum etc). All these factors which change along the length of streams are also the factors which control the distribution of the various sections of the biotic fauna and flora

Quantitative osteological study of a bottom feeder hillstream cyprinoid fish Crossocheilus latius latius (Hamilton- Buchanan)

The quantitative osteological study has been conducted on a Hillstream bottom feeder fish Crossocheilus latius latius. C. latius latius is a common hillstream fish of Snowfed Rivers of Alaknanda. The bones have been taken from different sized fishes ranged from 13 to 27 Cm in length and 39 to 132 gm in weight. The correlation is applied between Body Weight and the Weight of different disarticulated bones of C. latius latius. The correlation (r) is highly significant among the different parameter of body in relation to osteology which ranged from r = 0.952; P<0.1 to r = 0.999; P< 0.1

On the Design and Analysis of Parallel and Distributed Algorithms

Arrival of multicore systems has enforced a new scenario in computing, the parallel and distributed algorithms are fast replacing the older sequential algorithms, with many challenges of these techniques. The distributed algorithms provide distributed processing using distributed file systems and processing units, while network is modeled as minimum cost spanning tree. On the other hand, the parallel processing chooses different language platforms, data parallel vs. parallel programming, and GPUs. Processing units, memory elements and storage are connected through dynamic distributed networks in the form of spanning trees. The article presents foundational algorithms, analysis, and efficiency considerations.Comment: 9 page
