Abstract

Bamboo contributes as a source of long fiber in the pulp and paper furnish. The physical and chemical characteristic of bamboo as a raw material varied form species to species. The raw material having low lignin content reduces chemical consumption and pollution load during pulping and bleaching whereas high holocellulose content results in more productivity. Anatomical characters like fibre morphology is one of the important character which plays very important role on the structure and properties of the end products like paper and textile. The ratio of length and wall thickness affect the flexibility and collapsibility of fiber, which inturn reduces the energy requirement during beating. There is need to fill up the gap between demand and supply by raising quality bamboo.

Abstract

This paper is in continuation of earlier papers on systematic evaluation on working qualities of Indian timbers in which results of working qualities of seven more species namely Abies pindrow, Acacia tortilis, Leucaena leucocephala, Piciea smithiana, Paulownia species, Salix alba and Ulmus wallichiana have been reported after testing them under six major wood working operations - Planing, Sanding, Turning, Shaping, Boring and Mortizing. The working quality index based on quality of worked surface and ease of working for each species are reported along with the results of Tectona grandis for comparison. These results indicate that overall performance of Paulownia species and Ulmus wallichiana is better than Teak where as Acacia tortilis, Leucaena leucocephala and Piciea smithiana are comparable to Teak. These are easy to very easy to work with hand and machine tools.

Abstract

To meet the growing shortages of industrial wood, large scale plantations of poplars have been raised in the country. Poplar wood possesses high timber and fibre value for industrial applications. Several studies on different utilization aspects of Poplar, including its physical and mechanical properties, wood working and carving quality, and its suitability for plywood, hardboard, particle board and laminated wood etc., have been undertaken. The wood is now extensively used in the manufacture of plywood, match boxes and packing cases etc. With increasing availability of Poplar wood in coming years, it is necessary to study in detail clone-wise properties and utilization of Poplar species for diversifying the use of Poplar wood. This paper describes the recent research and development work carried out on Poplar wood utilization for reconstituted wood products at this Institute.

Abstract

Keeping in view the need for substitutes of conventional timbers like sissoo, teak, rosewood, sandalwood and walnut, the carving behaviour of eleven Indian timbers were studied systematically under four main carving operations, viz., chiseling, scooping, punching and fret sawing. On the basis of ease of working, occurrence of defects, cleanness of cutting edges, quality of carved surface etc., a quantitative method for comparing the overall carving behaviour with teak is developed and suggested. The results presented indicate that Acer oblongum (Maple), Michelia champaca (Champ), Himalayan species, Cupressus torulosa (Cypress) behave better than teak while Terminalia procera (Badam), Adina cardifolia (Haldu) and Olea glandulifera (Indian olive) behave comparable to teak.

Abstract

The paper gives a comparative account of the evaluatinn of Su-babul (L leucocpphala) ,grown in Pune. At Siliguri and Rajabhatkhawa, for bleached grade kraft pulp. The data on pulping and bleaching properties indicate that the wood from all the three sources can be pulped to obtain bleachable grade pulp (Kappa No 26 ± t) using 17% active alkali as Na₂O. The bleached pilip yield was about 45% in an the three cases. To achieve a pulp of 7% brightness CEH sequence with total chlorine application of 9.7% was adequate for samples for Pune and Rajabhatkhawa; whereas in case of Siliguri sample another stage of hypochlorite (2% av. Chlorine) was needed. The strength properties data indicate that wood of all the three localities is suitable for producing bleached kraft pulps for writing and printing papers. It was found that fibre characteristics (The Runkel ratio and shape factor) had marked influence on strenglh properties. The tensile index, tear index and burst index decreased with increase in the hunkel ratio and shape factor.

Abstract

The present paper gives a comparative account of basic density and kraft pulping characteristics of fourteen species of Barataung area and eighteen species of Middle Andman area of Andaman&Nicobar Islands. The properties of kraft pulps of individual species have also been evaluated. It has been found that the basic density varied widely with species in both areas. In Barstaung area the variation was from 0.302 to 0.847 g/cm², whereas for Middle Andaman gives area it was in between 0.261 to 0.728 g/cm². Laboratory experiments on kraft pulping of individual species have shown that most of them gave screened pulp in the range of 40-45% yield, the only exception being Mitraeyna retundifolia of Barataung area and Knema sp of Middle Andaman area which gave pulp yield below 40%. The physical strength properties of unbleached kraft pulps of all the species were found to be adequate for wrapping grade paper. Pilot plant trials have shown that the mixed species of both areas could be pulped wlth 18% active alkali (as Na₂O) to produce unbleached kraft pulps of about 45% of yield. The paper made from these unbleached kraft pulps on pilot paper machine was of satisfactory strength for use as wrapping paper. It was further established that these pulps could be bleached to 75 brightness by conventional C/E/H/H/ sequence to produce writing and printing paper.

Abstract

Unlike other resource management Sciences, the management of forests to yield maximum benefits is complicated. It is on account of heterogenity in size class distributions age structure, size of the population and linkage of meaning of maximum harvest with management objectives. With the harvesting policy the concept and types of rotation thus came into existance. During early years when scientific manament was evolved, the removal was cautious and restricted to trees of higher dimensions. Rotation was in consequential and so was fixed high. In due course of time uniform system based on natural regeneration was adopted to convert a forest into a series of age blocks. As technique of management became more and more refined the rotation fell in many areas thus allowing harvest of larger quantity of material. This was followed by complete artificial planting in suitable area and led to simple system of forest management cutting down further life span 10 of a crop in which trees of merchantable dimension could be produced, Mean while production had to be stepped up not only to compensate for the land lost to competing Uses but also to satisfy the increasing demand of rising population, Side by side appropriate technologies developed for various use wood even of small sizes.So attention was paid to identify various uses and demands with the view to relate these to the capacity of forests to improve the present level of production. This led to the introduction of exotics and intensive management of indigenous species which furtber resulted in reduction in rotation. The paper also summarises the information about totation of some prominent species and ther present trends.

Fuelwood is most important energy source meeting about 60% of its requirement, but there is hardly any exclusive plantation programme to raise fuelwood output. Presently species for which no are has been developed, defective wood and branchwood volume contribute towards fuelwood yield from natural forests. To increase yield fast growing fuelwood species can play a vital role. The approach to combat energy crisis is described. The maximum yields obtainable from differeat species under varied condition of growth are given and also a rating index to choose suitable species has been developed.

Abstract

An attempt is made to study growth and yield of Shorea robusta of taungys plantations in Gorkhpur Forest Division of Uttar Pradesh. Stocking influences crop diameter but total yield per unit areas does not vary substantially. The best level of stocking, for maximum stem volume down to 5cm diameter limit, appears to be about 1000 trees/ha at 40 years of age. However, where large sized timber is required forests can be worked at a suitable lower level of stocking without much sacrifice in total yield.

Abstract

TradiTIonal yield tables which are prepared for fully stocked stands are not of much help in introducing manipulations precisely in management of forests to achive maximum yield of desired product in shortest period of harvest. In effect what we need is the variable density yield table. The present stuay is towards this end. It is completely a mathematical approach, in which various regressions have been developed to account for the maximum possible variation present in the crop The species selected for the study is Eucalyptus grandis (Hill) Maideen.

Abstract

Mysore gum plantations have wide range of distribution. But on account of change in soil and climate, their growth is not same all Over Use has been made of dummy variables in multiple regression to group entire distribution into few similar regions of growth and yield. Estimates based on regions so delineated would be more accurate and explain variation in population from which they are drawn better than any haphazard attempt.

Abstract

The key factors which govern rotation for maximum volume production are site productivity' specification of products desired and stand stocking. Forest productivity is a function of site' products desired to be produced or can be sold are determined by demand or markets and so it is stand stocking only which can be manipulated to obtain maximum growth of desired product in shortest time. If stocking is very low' despite full growth by trees' production will be low. With high stocking' there is a stage beyond which growth does not increase with stocking and with further increase of stocking growth may decline because of stagnation. Now the question arises as to what is the level of optimum stocking? In the present paper attempt is made to identify this level by use of regression technique.

Abstract

The definition of stem standard timber form factor f_st is analysed. Presuming a tree to be conical, it is studied as to how much error in its estimation is introduced in calculating tree volume by Huber's formula and measarement by sections. f_st diameter curves for chir, kail, deodar and fir are drawn and comparative study is made. It is found that within a narrow range of diameter at breast height f_st height curve is linear. Taking advantage of this observation, the procedure of Hummel's "Volume-Basal Area Line" is applied in analysis of data for compiling f_st table for deodar with the difference that in the Present case, it is "f_st -Height Line" drawn for each diameter class. The values of f_st for predominant trees are compared with that of co-dominant and other trees of under-storey. It is revealed that suppressed trees on the whole show better form.

Abstract

Results of studies on ischolar_main and seed production and alkaloidal content of the ischolar_mains in the case of about 1,2 and 3 year old plants of Rauwolfia serpentina (Linn.) Benth. Ex Kurz being raispd under irrigated conditions at Kota are given. Average weight of air dried ischolar_mains per plant from 1, 2 and 3 year old plants is 22 g, 49 g and 162 g respectively. The total alkaloidal content of 1, 2 and 3 year old ischolar_mains was found to be 1.24, 1.31 and 1.50 per cent respectively and is well above the I.P. and B.P.C. standard (not less than 0.8 per cent). The seed production per plant comes to be 2.1, 3.6 and 8.0 g in case of 1, 2 and 3 year old plants respectively. The results of yield of ischolar_mains and their alkaloidal content from these plantations at Kota compare favourably with those obtained from plantations raised at Forest Research Institute, Dehra Dun. Possibility of extending the plantations of Rauwolfia serpentina in suitable localities in this state is indicated. Considering the increase in the yield of ischolar_mains with the age of plants, harvesting of ischolar_mains from 2 to 3 year old plants is suggested.

Abstract

Phyto-mass/carbon of under-storey vegetation play a significant role in carbon dynamics, wildlife habitat quality, biodiversity, soil conservation, soil organic carbon, soil fertility, etc. Above ground phyto-mass/carbon of under-storey vegetation consisting of components like shrubs, herbs, litter and humus of sal (Shorea robusta) forest has been assessed using ground observations and these contribute (0-)1-3% in total above ground phytomass. This assessment is based using satellite remote sensing data for characterising forests for homogeneous stratification map based on forest type, forest density and physiography. Above ground phytomass in shrubby layer varied from 1.76 t/ha in 'sal-teak mixed' (Tectona grandis) with 60-80% density to 5.16±SE 1.78 t/ha in 'pure sal' with >80% density. Phytomass in herbaceous layer was almost nil in the case of very high canopy density (>80%) in 'pure sal' forest, 'sal teak mixed' and 'sal mixed' forests. The highest phytomass 1.93±SE 0.17 t/ha is reported in 'pure sal' (10-40% density) followed by 'hill sal' (10-40% density) 1.49±SE 0.03 t/h and 1.27±SE 0.01 t/ha in 'hill sal' with 40-60% density. The open (10-40% density) to moderately degraded (40-60%) 'pure sal' forests have high potential for carbon sequestration. The carbon density in shrubs, herbs, and litter-humus layer showed variable trends with different forest density strata except litter-humus in 'pure sal and sal mixed' forests. The phytomass contribution of exotic shrub such as Lantana camara in the degraded forests would be useful for management planning.

Abstract

The NREGA addresses itself chiefly to working people and their fundamental right to live with dignity. The success of the NREGA, however, will depend on people's realization of the Act as a right. The issues involved in empowering workers are in the range of enhancement of knowledge levels, development of literacy skills and organizing workers. Enhancing social security levels of workers also needs to be considered. Another important task is to link NREGA with other developmental programmes. Empowerment of workers and creation of durable assets depend, in terms of their strategies, to a great extent on the linkages between NREGA and other development programmes. Linkages with human development programmes such as the National Rural Health Mission and the National Literacy Mission are needed to ensure basic human entitlements to workers that in turn will enhance their capacity to negotiate their rights under the Act. Linkages with other livelihood and infrastructure initiatives need to be considered for sustainable employment. The thrust of NREGA is on strengthening the natural resource base of livelihood. Initiatives for natural resource management also need to be dovetailed with income generation projects to enable workers to move from wage employment to self-sustaining employment. In addition to this, there is a need to improve the technological options for performances and monitoring.

Abstract

The rapid growth has helped Indian agriculture mark its presence at global level. India stands among top three in terms of production of various agricultural commodities like paddy, wheat, pulses, groundnut, rapeseeds, fruits, vegetables, sugarcane, tea, jute, cotton, tobacco leaves, etc (GOI, 2008-09). But with the change in phases, the improvements in agricultural technologies and practice means has resulted in more consumption of food per head available than 40 years ago.In addition to this increasing crop yields in many parts of the world, advances in agricultural technologies have also contributed to a safer food supply, and in some cases, improved environmental quality. Over the next 30 years, agriculture will have to sustain an additional 2 billion people from an increasingly fragile resource base. Ever-growing demands and increasing pressures on land and water resources mean that agriculture has to become even more productive, efficient and environmentally sound and to foster this will require the application of new technologies , scientific knowledge improved resource management and continued public and private research investment in emerging technologies. With the beginning of the new century, the world has to faced enormous challenges to meet the food, feed and fibre needs of a growing population with rising incomes. It has been estimated that by 2025 the global population will be approximately 7.9 billion, up from 6 billion currently. Global cereal and meat demands will increase by 46% and 56%, respectively.To put an end to and to conserve the natural resource "sustainability" is commonly seen as a property of an ecosystem. But sustainability can be seen from other perspectives, which are more relevant for extension. Environmental issues emerge from the human use of natural resources. Sustainability can, therefore, be defined in terms of human reasons, activities, and agreements. Sustainability emerges out of shared human experiences, objectives, knowledge, decisions, technology, and organization. Agriculture becomes sustainable only when people have reason to make it so. Other than the introduction of sustainability innovation is also playing an important role and it should also be incorporate in natural regenerative processes, such as nitrogen fixation, nutrient recycling, maintenance of soil structure and fertility, and protection of natural enemies of insect pests, weeds and diseases, into agricultural practices. These approaches can make better use of the indigenous knowledge of farmers and, where it can be appropriately , combine with new science-based technologies for optimum results.

Abstract

Augmentation of new genetic resources either through indigenous collections or by importing from other countries is an important activity of any crop improvement programme. Indian history had witnessed the invasion of many world communities like British, French, Portuguese, Dutch, Arabians, Muslims etc with whom a diverse genetic base of many crop plants were also introduced in the country's flora. Many of these species have been adapted well and naturalized in Indian climate and are being used in various facets of life. The pharmaceutical industry is also backed by many such plants. Of the forty major commercial medicinal plants utilized by the Indian pharmaceutical companies, about 27 per cent have originated in other countries. The percentage is still higher in case of commercial aromatic plants viz., 52 per cent of the total aromatic component. The gradual increase in the utilization of exotic plants by the pharma-aroma-companies is because many plants have been introduced into cultivation and are now a part of regular agriculture system. The National Bureau of Plant Genetic Resources (NBPGR), New Delhi under ICAR is instrumental in providing this genetic variability of medicinal plants at both fronts. The import of plant genetic resources into India is governed by Plant Quarantine (Regulation of Import Into India) Order, 2003. Access to genetic resources of Indian origin by foreign nationals is governed by Biological Diversity Act, 2002 of Government of India based on the principle of 'Sovereign rights of Nations' as promulgated under the legally binding Convention on Biological Diversity (CBD), 1992. The Convention provides for appropriate access to genetic resources and transfer of relevant technologies on mutually agreed terms, subject to prior informed consent.

Abstract

A comparison of the effect of gamma-rays ethyl methane sulfonate (EMS) and their combination for induced mutagenesis in two chilli varieties Kashi Anmol (KA-2) and VR-338 (Kashi Gaurav). 1000 chilli seeds each were irradiated with 10,15, 20, and 25 kR doses of gamma-rays treated, with 0.02, 0.03 0.04 and 0.05 M concentration of ethyl methane sulfonate and another 1000 seeds used for combination treatments were treated with all doses of gamma-rays followed by 0.03M EMS. The M1 generation was raised in protected nursery at Horticulture Research Farm, BHU, Varanasi during July 2011. Chlorophyll mutations were used to evaluate the mutagenic effeciency of various mutagens. The spectrum of chlorophyll mutants Albino, Chlorina, Viridis Xantha and Dark Xantha were most frequently observed in M₂ generation. Gamma rays induced higher proportions of chlorophyll mutants than EMS and their combination. However, frequencies of viable chlorophyll mutants were observed in higher EMS and gamma-rays treatments than with their combination. Treatment with 15 kR gamma-rays was more effective in inducing chlorophyll mutations with highest frequency. Mutagenic effect generally increased with increasing dose of and gamma-rays EMS and their combination.

Abstract

The prevalence of strongyloidiosis due to Strongyloides papillosus in goats in Kanpur region of Uttar Pradesh was studied and trial using arsenic 200 and cina 200 was conducted in goats tamed by the individual farmers during mansoon of the year 2012. Out of 80 examined goats aged above one year, 14 (17.5%) goats were found to be positive for Strongyliodes nematodes and multiple infection of trematode and cestode was also observed based on the faecal examination. For observing the efficacy of drugs, goats were randomly divided into three groups A, B and C of 3 goat each. Arsenic 200 @ 20 pills and cina 200 @ 20 pills twice a day were given orally to each of the goats group A and B while the goats of group C were kept as untreated control. Efficacy was observed by calculating on zero to 14 days post treatment by faecal egg count reduction test. The result of homoeopathic treatment by using the drugs arsenic and cina indicated 96.55 per cent and 98.62 per cent efficacy, respectively. It was found that Strongyloides papillosus appeared to be extremely resistant to drugs of arsenic and cina. It can be suggested that arsenic and cina were proved to be a better effective control on Strongyloides papillosus in goats without producing any side effect.

Abstract

In the present investigation, 300 cows milk samples were collected and these samples were screened out on the basis of California mastitis test (CMT) for estimation of clinical and subclinical mastitis in cow. Total 64.66 per cent prevalence rate was found, out of which 53 per cent and 11.66 per cent were found sub clinical and clinical mastitis, respectively. Most of the samples were positive to bacteriological examination and various type of bacteria were isolated, the most prevalent being Streptococcus aureus, followed by S. agalactiae, E. coli, Micrococcus sp., Enterobater aerogen, Bacillus sp. and Corynebacterium. Administration of trisodium citrate creates unfavourable pH medium in the quarter/udder retarding the infection. It was also observed that trisodium citrate administration increased the fat, S.N.F, milk yield, over the respective values of in mastitic milk.

Abstract

A field experiment was conducted during rainy season of 2013 at Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi to evaluate the effect of phosphorus levels and bio-organic sources on growth and yield of wetland rice cv. HUR-105. Factorial experiment was laid out in Randomized Complete Block Design involving four levels of phosphorus viz., control, 50 per cent RDP, 75 per cent RDP and 100 per cent RDP and three bio-organic sources i.e. PSB, PSB + BGA and PSB + BGA + FYM (5 t ha^-1) replicated thrice. Increase in the levels of phosphorus application upto 100 per cent RDP (60 kg P₂O₅ ha^-1) improved growth attributes, yield attributes, grain and straw yields. Combined use of PSB + BGA + FYM (5 t ha^-1) proved superior to PSB alone and PSB + BGA. Economic analysis indicated that integration of moderate phosphorus level (75% RDP i.e. 45 kg ha^-1) along with the use of PSB + BGA + FYM (5 t ha^-1) gave highest net return and B:C ratio.

Abstract

The present study is an attempt to determine the combined hepatoprotective potential of hydroethanolic leaf extracts of Murraya koenigii and Phyllanthus niruri against paracetamol (PCM) and ethanolinduced toxicity in human hepatoma HepG2 cell line. Toxicity in cells was induced by treatment with 15 mM PCM and 50 mM ethanol for 24 h as manifested by a significant (P < 0.05) decrease in cell viability, increase in the leakage of serum glutamate oxaloacetate transaminase and serum glutamate pyruvate in culture medium, increase in lipid peroxidation and reduction in reduced glutathione in cell lysate. These alterations were significantly ameliorated when cells were treated with a combination of hydroethanolic leaf extracts of M. koenigii and P. niruri, and silymarin during both prophylactic and curative studies. Both post-treatment (curative) and pre-treatment (prophylactic) with the combination of plant extracts were able show effective hepatoprotection. This was also evident during morphological studies. The combination of plant extracts thus holds immense potential for future use as a hepatoprotectant.

Abstract

Residues ofimidacloprid at 20 g a.i. ha^-1 and lambda - cyhalothrin at 15 g a.i. ha^-1 were estimated quantitatively by HPLC/GLC in/on brinjal fruits. Initial deposits of insecticides were higher in imidacloprid than lambda - cyhalothrin. Initial deposits of 0.652 mg kg^-1 of imidacloprid dissipated to 93.17 per cent on 10^th day. In lambda - cyhalothrin the initial deposits were 0.138 mg kg^-1 which dissipated to 92.75 per cent on 10^th day. The degradation of imidacloprid was relatively higher as compared to lambda - cyhalothrin. Both imidacloprid and lambda - cyhalothrin had half - life values of 1.92 and 2.65 days, respectively on brinjal fruits. The safe waiting period for imidacloprid was found 4.70 days. In lambda - cyhalothrin, no waiting period is required after its application as the initial deposits were less than its MRL (0.3 mg kg^-1).

Abstract

This article enumerates the findings of a team research on the Indian Himalayan timberline ecotone, with focus on three sites (located in Kashmir, Uttarakhand and Sikkim). Timberline elevation increased from west to east, was higher in the warmer south aspect than the cooler north aspect, and was generally depressed. Betula, Abies, Rhododendron and Juniperus were important treeline genera. The Himalaya has not only the highest treelines (Juniperus tibetica, at 4900 m), but also the widest elevational range (>1700 m). Remotely sensed data revealed that the timberline is a long, twisting and turning ecotone, traversing a length of 8–10 km per km horizontal distance. Surface temperature lapse rate in the monsoonal regions was lower (–0.53°C/100 m elevation) than generally perceived and varied considerably with season, being the lowest in December. The Himalayan treeline species are not water-stressed at least in monsoonal regions, predawn tree water potential seldom getting below –1 MPa. The upward advance of Rhododendron campanulatum (a krummholz species) may deplete alpine meadows with climatic warming. Tree-ring chronology indicated that winter warming may be favouring Abies spectabilis. Early snowmelt increased growth period and species richness. Treelines generally are stable in spite of decades of warming. Dependence of people on timberline was still high; so economic interventions are required to reduce the same.

Abstract

The mono-cropping system of farming is most prevalent in most parts of the Chhattisgarh. However, the mono-cropping system has certain disadvantages as compared to that of integrated farming systems. Thus, to evaluate the efficacy of this system a study was conducted to determine the relative efficiency of integrated rice-duck-fish farming as compared to conventional rice-rice, duck-duck and fish-fish farming system. For present investigation, a field experiment was conducted at Integrated farming system model developed on 1.0 hectare of irrigated land at the farmer's field of Raigarh district. The data was calculated for its economics based on the rates prevailing during the study period while, labour requirement for various activities in duckery and fish production were recorded and given in man days per hectare. The system productivity, B:C ratio, employment generation was higher for IFS. The labour use efficiency was higher for fish-fish, duck-duck farming systems as compared to Integrated farming system. Thus, we can conclude that Integrated farming system was much better, economical and profitable as compared to that of mono-cropping system of farming.

Abstract

Man-made forest fires in the traditionally populated zone (about 800-2000 m altitude) are common in much of the Central Himalaya, and are a major topic of environmental debate. This study based on an analysis of data of the State Forest Department at Uttarakhand on incidence of forest fires shows that these are high-frequency, low-severity surface fires of small size, largely determined by the moisture conditions of the pre-monsoon season (from March to mid-June), and the traditional practices of biomass collection by local people.

Abstract

In a multi-hop mobile ad-hoc network, mobile nodes cooperate to form a network without using any infrastructure such as access points and base stations. Instead, the mobile nodes forward packets for each other's allowing communication among nodes outside wireless transmission range. Examples of applications for ad-hoc networks range from military operation and emergency disaster relief to community networking and interaction among meeting attendees or students during a lecture. In this ad-hoc networking applications, security is necessary to guard the network from various types of attacks. In ad-hoc networks, adverse nodes can freely join the network, listen to and/or interfere with network traffic, and compromise network nodes leads to various network failures. Since routing protocols are a fundamental tool of network-based computation, attacks on unsecured routing protocols can disrupt network performance and reliability. Multicasting is a more efficient method of supporting group communication, as it allows transmission and routing of packets to multiple destinations with fewer network resources. Multicasting can improve the efficiency of the wireless links, when sending multiple copies of messages, by exploiting the inherent broadcast property of the wireless medium when multiple mobile nodes are located within the transmission range of a node. Providing efficient multicasting over MANET faces many challenges, including dynamic group membership and constant update of delivery path due to node movement.

Abstract

Accuracy of distance measurement of an object from an observation point such as a stationary or moving vehicle, equipment or person is most important in large number of present day applications. Ultrasonic sensors are most commonly used due to its simplicity and low cost. The accuracy of the measured distance is dependent on the separation between the ultrasonic transmitter and receiver. This dependency has been studied and reported in this paper. The result shows that the accuracy of distance measured is dependent on the separation between the transmitter and the receiver.

Abstract

Ad hoc networks are gaining increasing popularity in recent years because of their ease of deployment. No wired base station or infrastructure is supported, and each host communicates one another via packet radios. In ad hoc networks, routing protocols are challenged with establishing and maintaining multihop routes in the face of mobility, bandwidth limitation and power constraints. In this dissertation, we study the routing strategies for ad hoc networks. On-demand routing protocols and table-driven algorithms are analyzed and compared against each other. Our study shows comparison between routing strategies like Dense mode and Center Mode.

Abstract

The near unmanageable requirement of dwellings and other buildings faced up with inadequate resources and manpower can be sobered down to an extent by applying a few managerial techniques during the construction. For instance, methods improvement of various operations by way of introducing simple and ordinary gadgets and tools, improving the work place layout and arranging the motion or working pattern sequence to obtain an overall rhythm and smoothness in the process to increase the productivity and quality as well. For jobs that are highly repetitive, such as, manufacturing of precast building-components, a well conceived production plan having a well organised layout, balanced labour gangs, and optimum quantity of moulds, equipment and materials will bring about nothing but efficiency and cost reduction.

Improved methods of brick-laying, plastering and formwork developed at the Central Building Research Institute, Roorkee, and production planning for precast roofing and walling components will be described in the paper.

Abstract

The Himalayan region extends all along the Northern boundary of India. The diverse ecohabitat of Himalayan region hosts a wide range of plant diversity as well as crop diversity on which native people rely for their food and nutritional security. Traditionally, agriculture on hills was practiced on a subsistence basis but, with the development of means of transport, storage facilities and other infrastructure, hill agriculture has become commercial in character. The present study has been carried out in Bhaderwah and Bhalla blocks of Doda district of J&K state which fall in the North-Western Himalayan region of J&K state. A sample of 100 farmers was drawn for the present study which comprised of 78 marginal farmers, 14 small farmers and 8 medium farmers. Primary data were used to analyze the results.The results revealed that both marketable surplus as well as marketed surplus was higher in case of medium farmers followed by small farmers and marginal farmers. It was found that three types of marketing channels mainly channel-I (Producer - Village Trader - Retailer – Consumer), channel-II (Producer – Retailer – Consumer) and channel-III (Producer – Consumer) were involved in the marketing of Rajmash in the study area. The total marketing cost and marketing margin was found higher in channel-I followed by channel-II and channel-III. The results also indicated that the marketing efficiency of channel-III (1.85) was highest as compared to channel-II (1.44) and channel-I (1.28) and the producer’s share in consumer’s rupee was also maximum in channel-III (97.51 %) followed by channel-II (82.49 %) and channel-I (76.25 %) in the study area.

Abstract

Dairy enterprise could play a more constructive role in promoting rural welfare and reducing poverty by generating employment at farm level is increasingly being recognized. The present study was conducted on 160 dairy farmers selected from 12 villages of Hisar and Jind districts of Haryana to assess the self-confidence among dairy entrepreneurs about animal husbandry practices. Self-confidence was measured by using innovative scale which consisted of five practices in respect of the dairy management. The respondents were grouped into three categories namely low, medium and high level of self-confidence using mean and one standard deviation. The data were collected through pre-tested structured interview schedule by holding personal interview with the dairy farmers during 2014-15. The overall analysis revealed that 36.88 per cent of dairy farmers had medium level of self-confidence while 33.1 per cent and 30 per cent of dairy farmers were having low and high level of self-confidence, respectively. It is evident from the correlation analysis that educational qualification, size of land holding, annual income, caste, dairy farming experience, extension contact, social participation, mass media exposure, economic motivation, scientific orientation, attitude towards dairy farming and market orientation showed positive and significant relationship (P<1) with self-confidence of dairy farmers while age also having significant but negative correlation with self-confidence of dairy farmers. The negative correlation of age with self-confidence of dairy farmers may be attributed to the reason that with the advancing age farmers become more inclined towards traditional practices due to lack of energy, change proneness, decision making ability and progressive attitude. Almost similar results were also seen in case of small, medium and large categories of farmers. Further, regression analysis revealed that two independent variables namely, caste and economic motivation were found to have positive and significant values of ‘t’ for ‘b’. The multiple co-efficient determinant (R²) further implies that all the thirteen variables had together explained 91.25 per cent of variation towards self-confidence of dairy farmers.

Abstract

Analysis of variability carried out for ten characters in sixteen diverse genotypes of nigella (Nigella sativa L.) revealed high genotypic and phenotypic co-efficient of variations for secondary branches per plant, number of grains per fruit, number of fruits per plant, length of fruit (cm) and width of fruit (cm). Heritability estimates were high for number of grains per fruit (0.86), number of fruit per plant (0.78), length of fruit (0.64), days to maturity (0.59), number of secondary branches per plant (0.56) and yield per plant (0.47). Higher genetic advance as percentage of mean was recorded for number of grains per fruit (46.11%), number of secondary branches per plant (43.99%), number of fruits per plant (39.65%), yield per plant (24.49%), length of fruit (24.12%) and indicating additive gene effect. Quantitative traits like days to maturity, number of secondary branches per plant, number of grains per fruit and number of grains per fruit exhibited wide range of variability (134.33-143.00) maximum genotypic co-efficient of variability (29.53), maximum phenotypic co-efficient of variability (22.18), broad sense heritability (0.86) and gene gain (46.11).

Abstract

Lilium is one of the important bulbous flowers grown in Kumaun hills of Uttarakhand. Present study aims at examining cost incurred in production in terms of percentage and investigating the existing marketing system. The study reveals that the operational cost during first year was the most important item of cost, accounting for 37.32 per cent of the total operational cost. Cuttings formed the chief component of material cost accounting for 97.57 per cent of the total material cost. Cost of production was very high in first year due to high labour and material cost. The yield per hectare was estimated to be 121982 spikes in the first year. Thereafter, yield declined and decreased to 98806 in third year. It is found that lilium cultivation is economically viable.The investigation also reveals that two marketing channels exist in the marketing of lilium flower in the study area. The marketing cost as percentage of consumers rupee, borne by producer in channel-I was 6.41 per cent and 6.36 per cent in channel-II. It was found that retailers get higher relative share in consumer’s rupee. It is suggested that liberal credit facilities need to be made operative for farmers, as Lilium is highly capital intensive enterprise. Development of wholesale markets close to production clusters and related infrastructure in terms of storage, packaging, transport and market information also need to be strengthened to give a boost to production and return from the market.

Abstract

The concept of CSR originated in thie fifties of tfie last century wlien Howard R Bowen wrote a seminal book Ttie Social Responsibilities of a Businessman (Carroll takes him to be the father of CSR (Carroll, 1999)) Since then the notion of CSR has come to dominate the society business interface and many theories and approaches have been proposed, many definitions have also been given in order to understand and explain the concept. Although the concept has normative origins, a lot of literature has attempted to give positive hue to the concept by linking firm's performance with the performance on CSR. Some have gone ahead and suggested that the CSR notion can be strategically used by companies to gain competitive advantage while some continue to take the stance that it is the moral duty of a business to be socially responsible regardless of its impact on the profitability of the company. The CSR literature is dominated by this dichotomy of approaches mentioned hereinafter as altruistic CSR and strategic CSR. The paper takes a critical look at these two approaches and attempts to define the notion of CSR and its two dimensions strategic and altruistic CSR

Abstract

In clinical practice dermatological reactions are common but comprehensive information regarding their incidence, severity is often not available as many cases go unreported. The objective of this study was to evaluate the types of dermatological adverse drug reactions (ADRs) in a tertiary care hospital and determine their causal relationship with the offending drug. This prospective, observational study was conducted at GSVM medical college Kanpur, Northern India for one year. Patients of all age and either sex were included. Dermatological adverse drug reactions were reported by the physicians of various department of the hospital and their causality assessments were performed as per World health organization (WHO) Uppsala monitoring centre (UMC), Expanded Rawlins and Thompson’s classification was used for determining type of ADRs, outcome and seriousness of ADR were assessed as per WHO. Descriptive statistics were used for data analysis. A total of 105 dermatological adverse drug reactions were reported from various departments of this tertiary care hospital. Most of the adverse drug reactions were observed in the age group of 0–20 year. Rash (35 ADRs) was commonly reported reaction. Anticancer drugs lead to 48 ADRs (mainly with Paclitaxel+Carboplatin-11, Adriamycin+Cyclophosphamide-7), followed by Antibacterial with 28 ADRs (mainly with Vancomycin-6, Cefixime-4 and Amoxicillin-4). A total of 8 ADRs were of serious type mainly with Vancomycin-Red man syndrome-6, Carbamazepine-toxic epidermal necrolysis-1 and Nimesulide-Steven Johnson Syndrome-1. Most of the adverse drug reactions on causality assessment were possible (77, 73.33%) and Probable (28, 26.67%) in nature. Type -B ADRs account for 2/3rd of the total dermatological ADRs. It’s highly emphasized for careful monitoring for ADRs associated with high risk drugs and more awareness should be created.

Abstract

India is the second largest wheat producer in the world after Russia. Wheat harvesting in the country was traditionally done using a sickle, a hand tool. However, in the last two decades, combined harvesters have been extensively used. The rapid development of mech­anization has resulted in the production of dust and straw particles during the harvesting operation of wheat. These particles have severe health hazards for the machine operator. Exposure to various types of particulate matter has a variety of effects on human health. Such an effect can be minimized if the concentration of the generated particle is maintained within a permissible limit. Hence, the present study has been conducted to evaluate and categorize dust and straw particles in the workspace of a combine harvester operator during wheat harvesting. An image-processing technique was used to study a field data sample collected on sticky paper. It describes a novel method of collecting dust and straw particles while harvesting wheat. Few studies have been conducted in developing countries to analyse the characteristics of dust and wheat straw exposure of combined harvester operators. The number of dust and straw particles deposited per square millimetre was 9–12, with sizes ranging from 10 to 1400 mm. The extracted data were divided into three groups, viz. thoracic, inhalable and straw and modelled using machine learning algorithms, including support vector machine (SVM) and k-nearest neighbor. With an accuracy of 96%, SVM outperformed the other methods for categorising dust and straw particles, whereas linear discriminant analysis performed poorly with an accuracy of 88%.
