Opis:: Oscillation criteria are obtained for nonlinear homogeneous third order differential equations of the form $y''' + q(t)y' + p(t)y^α = 0$ and y''' + q(t)y' + p(t)f(y) = 0, where p and q are real-valued continuous functions on [a,∞), f is a real-valued continuous function on (-∞, ∞) and α > 0 is a quotient of odd integers. Sign restrictions are imposed on p(t) and q(t). These results generalize some of the results obtained earlier in this direction.

Opis:: Mouse chromosome 11 was analyzed for the presence of quantitative trait loci (QTL) affecting body weight and fatness. Significant differences in allele frequencies (p<10-2) between two growth differentiated mouse lines DU6 and DUKs were proven at the marker loci D11Mit120, D11Mit125, and D11Mit126. In families which were derived from crosses between DU6 and DUKs cosegregation of genetic marker alleles and individual trait performance was analyzed. Variance analysis proved highly significant phenotypic differences between genotype groups (p<10-5), localized in one family in the chromosomal part between D11Mit236 and D11Mit126. These results were confirmed in independent families of parallel crosses. The detected chromosomal region affected both, body weight and fatness.

Opis:: Forest cover in hills is essential to maintain environmental, economic and ecological balances. North Bengal accounts for 3,086 sq km (26 %) of the 11,876 sq km area of classified forests in the state, and for nearly 5,000 sq km (40 %) of all land under tree cover. Upper Chatakpur is one of the emerging ecotourism spots of north Bengal, located at an altitude of 7887 feet in Darjeeling district. It is a 180 years old ethnic village with 19 houses and a population of about 89, and at an altitude of 7887 ft. It is about 8 km. from Sonada (26° 57' N, 88° 16' E), 22 km. from Darjeeling (26° 2' N, 88° 15' E) and 72 km. from Siliguri (26° 42' N, 88° 25' E). Upper Chatakpur Village situated within Senchal Wildlife Sanctuary, Darjeeling. The sanctuary with an area of 38.88 sq. km has an elevation of 1500-2600 m. The survey work was done in December, 2014 by visiting upper Chatakpur village and the primary data were gathered through field survey and direct contact with common people and authorized centers of the region. Surveys on the topography, demography, agriculture, livestock, water management, education, culture, health, waste management, transport, biodiversity, human animal conflict were done in this area. Medicinal plant diversity was studied in the village area and information was gathered from the local forest department centre. Information regarding the transport system was collected from the local transport office and syndicate. Census report was collected from the Sonada Panchayat Office. Health and education information was collected from the local primary school and the local sub health centre. Information on sustainable agricultural practices and waste management policies is collected through surveys in the village houses and agricultural fields. Biodiversity of Senchal Wildlife Sanctuary was documented by visiting the forest areas. Pictorial documentation was done in every phase of study. In spite of getting so much attention in the recent time, the village is not adequately developed. There is an urgent need for implementing sustainable management systems in the areas for the betterment of the socio-environmental structures. Some of the possible management strategies have been suggested for maintaining the social, environmental, economic and ecological balance of the region.

Opis:: Managing customer relationship is a great challenge in the present era of service revolution. As large numbers of players are now entering into this industry, the intensity of competition is growing among them in very passing day. In the current cut throat competition, customers are becoming very particular to use or not to use services of any organization. Therefore, managing customer relationship is playing dominant role for in almost every service providing organizations, so banks are not an exception. There is a popular belief that higher the emotional intelligence of service provider better will be their ability to manage customer relationship. So the present study is the part of a large study conducted on 300 bank employees working in 5 different banks (both in public and private sector) in the state of Chhattisgarh to assess whether their demographic variables, emotional intelligence and ability to manage customer relationship are related with each other. Data were collected with the help of a schedule to measure emotional intelligence and ability to manage customer relationship and are analyzed with help of ANOVA and Correlations by using SPSS. The study reveals that there exist significant and strong relationship between emotional intelligence, demographic variables and ability to manage customer relationship. Thus, it is concluded that service providers in banks with their high level of emotional intelligence and ability to manage customer relationship can contribute significantly to attract and retain customers and build long term relationship with them.

Opis:: Emotions in humans are subjective conscious experience characterized by psycho-physiological expressions and behavioral reactions. It may act as tool, if positively identified by complementing and enriching job performance but if negatively understood can ruin feelings and be a disaster. Emotions in healthcare organizations are important to be taken care of because in the service exchange process emotions of both the service provider and the receiver are directly involved. Although caring and curing patient by these employees is a professional activity but still, the empathetic and sympathetic behavior shown by these professionals influences their performance and success in hospital industry. Moreover, the behavior shown by these employees in the workplace is often discriminated on the basis of their gender as it influences the performance of health professionals. Based on above backdrop, the objective of the current study is to assess whether there exist difference in emotional intelligence of healthcare employees in hospitals with respect to their gender. A standardized questionnaire was used to conduct the study among 300 employees in hospitals with the help of scale developed by Hyde, Pethe and Dhar (2002). Data was analyzed through SPSS and results indicated that the level of emotional intelligence among females is higher than male employees.

Opis:: Two tricomponent room temperature nematic eutectic mixtures ABC and ABD with laterally fluorinated constituents A and B were prepared as base mixtures for vertically aligned mode LCD's. The physical properties of these mixtures viz. birefringence, dielectric anisotropy, bend elastic constant, relaxation time and rotational viscosities were determined in order to compare with the optimum values required to achieve the target specifications of VA mode materials. The dielectric anisotropy, Δ ε, and optical birefringence, Δ n, of these mixtures were found to be in the range of (-1.3 to -1.4) and (0.13 and 0.14), respectively, at around 20°C. The figure of merit for the ABD mixture has been found to be higher than that of ABC mixture throughout the entire temperature range. The pretilt angle effect in the physical parameters has also been studied. At T=20°C, the response time decreases to 25% and 35% for mixture ABC for 2° and 5° pretilt respectively in comparison to zero pretilt. On the other hand, at the same temperature for the ABD mixture these values are reduced by 16% and 35%, respectively.

Opis:: Two tri-component mixtures as base mixtures for vertically aligned mode LCD's were prepared. The eutectic compositions were theoretically estimated and experimentally verified from differential scanning calorimetry studies. A room temperature nematic mixture with fairly broad operating range emerged from each of the tri-component mixtures. The optical birefringence of these mixtures at the eutectic composition was measured as a function of temperature. X-ray diffraction measurements were done on these mixtures to obtain the orientational order parameters as a function of temperature. The order parameter values were also determined from birefringence measurements and the results were compared with mean field theory. Structural parameters like intermolecular distance and apparent molecular length have also been determined.

Opis:: An analysis is presented to investigate the effects of thermal radiation on a convective slip flow of an electrically conducting slightly rarefied fluid, having temperature dependent fluid properties, over a wedge with a thermal jump at the surface of the boundary in the presence of a transverse magnetic field. The reduced equations are solved numerically using the finite difference code that implements the 3-stage Lobatto IIIa formula for the partitioned Runge-Kutta method. Numerical results for the dimensionless velocity and temperature as well as for the skin friction coefficient and the Nusselt number are presented through graphs and tables for pertinent parameters to show interesting aspects of the solution.
