The human-elephant conflict study conducted between 1995 to 1997 records occurrence of 62 elephants in South West Bengal , inhibiting 3 ,368 km2 , in four localized sub.groups (n=26) and the group (n=36) that seasonally migrates from adjoining Dalma Wildlife Sanctuary , Bihar. Occurrence of intense crop depredation was only 5.5% of the total cultivated area available within the movement range of elephant. Landscape mosaic with cropland to forest ratios of 1.2:1 respectively had high depredation. Intensity of crop damage was higher between Sept. to Dec. (51.8%) followed by Jan. to Apr. (33.6%) , and May to Aug. (14.5%). The estimated crop loss was Rs. 3.2 crores. On an annual basis 13 people are being killed most of which occurred between Jan. to Apr. (48.52%) in post paddy season. Adult males in localized sub.groups were responsible for most (72%) of the human kills. Population management of these elephants through translocation or removal must be seen and integrated with the overall national planning for elephant management.

Virtual LANs (VLANs) offer a method of dividing one physical network into multiple network; in other words VLAN divides single broadcast domain into multiple broadcast domains. However, VLAN-enabled switches cannot, by themselves, forward traffic across VLAN boundaries. For inter-VLAN communication, a Layer 3 router is required (Dell, 2004). In this paper we discuss the VLAN protocol and provides step-by-step commands for configuring VLAN routing using the Cisco 2950 switches, we will also demonstrate creation of VLAN and Inter-VLANs communication with the help of Packet Tracer 5.2. (For free download www.packet-tracer.com/) With the help of this paper, Network administrator can increase performance of network, improve manageability of network and increase security options.Keywords

Drishtikon: A Management Journal, Vol 2, No 1 (2010), Pagination:Abstract
In every aspect of an individual's life, Stress is an integral part. Due to the growing competition at the workplace the stress level has also increased. At workplace, as in other areas stress can play a positive role by increasing alertness among staff and mobilizing their adaptive capabilities. Therefore, to some extent, a certain level of stress has the potential to actually contribute to organizational effectiveness. But stress can become counterproductive once the excessive levels of unresolved stress begin to affect the health and productivity of work force. . In fact, occupational stress has been defined as a "global epidemic" by the United Nations' International Labor Organization. The present research paper is an attempt to examine the sources and effects of work place stress among the Management and Technical faculty members of different academic institutions in Agra-Mathura region. For this purpose the data was collected by convenience random sampling of Management and Technical faculty members. The analysis has been done using different Statistical tools with the help of SPSS. The research suggests that there is no correlation between gender and the other demographic factors (age, designation, income, Change in personal habits etc). It was also found that most of the factors related to the measurement of stress level equally effect the stress level of technical and management faculty such as absenteeism due to stress and difficulty taking vacation/holiday/time etc.Keywords

HR practices have been developed in the context of industrial change and economic development. Managers in the organizations would be confronted with the need to reorient culture, thinking and paradigms. HRD as a function and as a prime mover would need to focus on this changing and emerging role. There are very few evidences where values or organizational culture is directly linked to HRD practices of the organization. This study att-empts to examine the effect of HRD practices on organization culture of some leading private and public sector organizations in India. The study revealed that the human resource development practices are a strong predictor of organi-zational culture both in private sector and public sector organi-zations in India. There is ample demonstration of meaningful relationship between HRD prac-tices and organization culture.References

A field trial was carried out for two years to ascertain performance of marigold (var. Pusa Narangi) planted at three spacings and on six different dates at bimonthly interval i.e. on first day of March, May, July, September, November and January. The crop planted on 1st March showed early flowering compared to other planting dates. The best performance with respect to flower size, weight and number of flowers per plant was recorded with 1st September planting. The highest number of branches and plant canopy spread were attained with May and July plantings. In both the years wider spacing of 40 cm × 40 cm produced best results with respect to maximum flower diameter, weight of individual flower and number of flower per plant. However, the total best yield per unit area was higher when the crop was planted on 1st September at 40cm × 20 cm spacing.Keywords

Polyurethane (PU)-based pressure-sensitive adhesive (PSA) tapes are commonly used during surgery. Such devices made for biomedical applications must be biocompatible and biologically safe while in use in the human body as their ingredients may leach off of a device into an adjacent tissue and can harm the body during or after application. In the present study, various methods required for biocompatibility establishment, e.g. cytotoxicity, irritation and sensitization for a device, have been analysed and presented following suitable specifications. The study also emphasizes on the developmental and curing mechanism of biomedical adhesive tape by electron beam (e-beam) irradiation.Full Text

Considering the impacts of industrial effluents on the water quality of many ponds, reservoirs, lakes and rivers as reported in the literature, the present study of water quality of a polluted pond was undertaken. Several physico-chemical parameters of the polluted pond namely Suman Lal Ka Pokhara were analysed to evaluate its suitability for washing, pisciculture and irrigation purposes by determining parameters like water temperature, pH, conductivity, DO, alkalinity, total hardness, BOD, nutrients, etc. Water was found acidic. Contents of chloride and TDS were not within the limits accepted for irrigation. Other parameters also suggested that the pond is not fit for other purposes also.Keywords

Though improvements in processing and technology are important, the fluctuating price of inputs such as molasses, corn, sugar beet, sugarcane, sweet sorghum, starch, etc. and their seasonal availability play an important role in ethanol industry. As a matter of fact, the ethanol industry based on conventional resources has reached its saturation point. Technologies for ethanol production from lignocellulosics are being developed by scientists world over with the objective of exploiting the potential of a resource, which is otherwise considered a waste, to generate energy. The focus has been to produce ethanol in a cost-effective manner, besides aiming to find use of its by-products as food supplements for cattles, etc. Recent developments like adoption of technologies such as dry grind fractionation, which is now commercially viable, would reduce the cost of milling; wet milling being cost-intensive and dry milling requiring smaller plants.Keywords

The rising level of carbon dioxide (CO2) in the atmosphere is a major concern, as scientific evidences show that it is the primary cause of global warming. CO2 concentration is expected to double by the middle or end of the 21st century, with a temperature rise between 1.5°C and 4.5°C (ref. 1). The importance of agroforestry as a land-use system is receiving wider recognition not only in terms of agricultural sustainability, but also in issues related to carbon sequestration or climate change.Full Text

Polyglycolide–caprolactone (PGCL)-based copolymer was synthesized from glycolide and caprolactone by ring opening polymerization in the presence of stannous octoate catalyst and diethylene glycol initiator. The effects of prepolymerization time, monomer ratio, monomer-to-catalyst and monomer-to-initiator ratios on per cent weight conversion were optimized. The end-capped copolymer was synthesized to make absorbable sutures having controlled bioabsorbability at different pH levels. It was observed that endcapped absorbable copolymer was more stable at pH 10.0 compared to uncapped absorbable material. End-capped copolymer also retained higher tensile strength compared to uncapped copolymer after 21 days. This phenomenon of controlled hydrolytic degradation of PGCL-based bioabsorbable polymer having terminal group end-capping can be attributed to less availability of hydrophilic end groups facilitating hydrolytic degradation of polymers.Keywords

Ultrasound non-linearity parameter (B/A) is determined using finite amplitude method. Second harmonic was generated on account of non-linear propagation of ultrasonic wave through the biological tissues. Transmitting transducers of 1.0 and 2.0 MHz and receiving transducers at double of these frequencies at 2.0 and 4.0 MHz were used. The second harmonic was analyzed and recorded. Biological samples under investigation were liver, kidney and spleen obtained from freshly sacrificed goat. Another group of samples were placed in 10% formaldehyde for 48 hours. The values of B/A for fresh liver, kidney and spleen turns out to become 7.48±0.05, 6.75±0.03 and 9.8±0.06 successively. However, in case of formalin fixed tissues the values were found to increase in all the samples to 7.52±0.04, 6.82±0.05 and 9.91±0.04 respectively. It appears that the trend of increasing B/A value is related to the structural, composition and state of the specimen. These observations, therefore, suggest the use of the nonlinearity parameter B/A in tissue characterization, particularly since structural alteration often attends the pathological state of the tissues.Keywords

The feasibility of using solid nanoparticles as ultrasound contrast agent have been called into question on the ground that the size of a nano-particle is much smaller than the wavelength of ultrasonic wave, therefore, backscattering from these particles will obviously be poor and hence, poor echogenicity would give poor image quality. However, appropriate size metal nanoparticles exhibit some important properties, such as, bio-conjugation and Enhanced Permeability Retention (EPR) effect.
Due to different acoustic impedance of solid nanoparticles than that of the biological tissues, the solid nanoparticles become a better ultrasound contrast agent than that of microbubbles. When solid nanoparticles are exposed to ultrasound waves during imaging they remain stable. In present work, we have synthesized solid nano-particles of gold to study its applications as Ultrasound Contrast Agent (USCA). With existing ultrasound technology, it appears that gold nano-particles of size 10 nm may not be suitable for Ultrasound Contrast Agent (USCA) as it failed to improve image brightness or even image quality. The size of nanoparticles are very small, therefore, it circulate inside the region of interest (human body) for sufficient duration to complete the imaging process.
