Opis:
The majority of the drugs on the market today are entirely chemically synthesized in the laboratory. Several scientists had synthesized dihydropyrimidine (DHPMs) derivatives showing a wide spectrum of biological actions as antibacterials, antivirals as well as antitumor agents. This activity is principally due to presence of steriogenic carbon C4 in their structure. The current investigation is comparative study of chemically synthesis of two DHPMs derivatives by Biginelli Reaction using microwave irradiation and conventional method. The synthesis of DHPMs derivative involves a multicomponent reaction (aldehyde derivative, urea /thiourea and 1,3-dicarbonyl compounds) in presence of HCl / NH4Cl as a catalyst. Two derivative viz. 3,4-dihydropyrimidin-2-(1H)-ones and 3,4-dihydropyrimidin-2-(1H)-thiones were synthesized and characterized using IR. The melting points were obtained are 203 °C and 211 °C respectively. Microwave irradiation was easy and gave more yield than conventional method. This study will help to develop easy protocol for the synthesis of many more DHPMs derivative with high yield.

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.

Managing Customer Relationships
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:
The electronic structures and optical matrix elements of CdSe semiconductor quantum dots of near cubical, hemispherical and cylindrical shape embedded in ZnSe were calculated. Bulk Hamiltonian matrices were obtained using the empirical tight binding method including spin-orbital coupling and relativistic effects. All quantum dots were simulated in reciprocal space and the number of atoms in each quantum dot was kept nearly equal for the comparison purpose. An adjacency matrix was produced which indicates the adjacencies of unit cells and the bulk Hamiltonian was included for each adjacency point in order to obtain the quantum dot Hamiltonians. The strain effects, valence band offset and spin orbital coupling were included in the calculations. The quantum dot Hamiltonian was solved to obtain the highest and lowest eigenvalues from which the electronic structure was obtained. Then eigenvalues near integers ranging from the lowest eigenvalue to highest eigenvalue was generated for the point.

Opis:
Polybutylene Terephthalate (PBT) / Polycarbonate (PC) nanocomposite blend was fabricated using melt blending technique in a twin extruder. The blend composition was optimized at PBT-PC weight ratio of 80-20. The effect of incorporation of various organically modified Montmorillonite (OMMT) and naturally occurring sodium Montmorillonite (MMT) on the mechanical, thermal and morphological properties of the nanocomposites blend has been investigated. It was observed that the Izod impact strength, tensile strength and flexural strength demonstrated a significant increase with the increase in clay loading from 1-7 weight % due to homogeneous dispersion of clay within the blend matrix. Thermo gravimetric analysis (TGA) revealed an increase in thermal stability of the blend with the incorporation of nanoclay. There is also decrease in the melting temperature (Tm) and crystallisation temperature (Tc) as observed from DSC thermograms. DMA add the evidence for TGA, DSC and mechanical results. PBT - PC blend with clay exhibited featureless XRD indicative of exfoliated structure. TEM micrographs also confirm the same that the clay has exfoliated into individual layers.

Opis:
We carried out a detailed study of the kinetics of oxidation of N'-ferrocenylmethyl-N'-phenylbenzohydrazide (FcX) to ferrocenium ion (FcX+) in aqueous and organic mediums. This study using cyclic (CV) and rotating disk electrode (RDE) voltammetry showed that the FcX/FcX+ redox couple is reversible. The N'-ferrocenylmethyl-N'-phenylbenzohydrazide and ferrocenium ion diffusion coefficients (D) were calculated from these results. In addition, the electron transfer rate constant and the exchange current density for the oxidation of ferrocene were determined. A comparison of the kinetic data obtained from the two electrochemical techniques appears to show that the data from the RDE experiments are more reliable because they are collected under strict mass transport control. Have studied lake close to neutral pH - 7.67 to 7.73. All lakes in accordance with the classification of the European Union Water Framework Directive have been included in the first class. The concentration in the surface layer of Ptot. Lake is little differentiated, is at level II quality class according to the classification of the European Union Water Framework Directive. Tested water lakes were changing the concentration of the PO43-diss - these concentrations correspond to water quality from III. The increase of the concentrations of phosphorus in the Lake may indicate a decrease in the amount of oxygen in the waters of the shallow and changes their status to release phosphorus compounds accumulated redox in sediment bottom. In the case of nitrogen-compounds nitrates and nitrites values for these indicators were at level I and II class in all the surveyed lakes in accordance with the classification of the European Union Water Framework Directive. Indicator, which indicates the high productivity of Lake is the biochemical oxygen demand (BOD5). The level of this indicator values on the studied Lake was on level III class. In the remaining Lake oxygen concentration was similar (continued in I class). Fauna of the Resko Lake bottom during summer stagnation was poor in terms of quality, which proves its considerable biological degradation. In terms of the concentration in the test macrozoobenthos Lake dominated, and Oligochaeta, Diptera larvae.
