    There has been a long-standing interest in the study of organizational climate among organizational researchers. Its importance is partly due to its hypothesized relationship to other organizational phenomena including job satisfaction, job performance, leadership behaviour and the quality of work group interaction. Research on the contribution of people management to organizational performance outcomes such as productivity and profitability has been related to a climate of satisfaction in the workplace. Job satisfaction along with organizational climate plays a vital role in retaining the employees by enhancing their commitment towards the organization. The present paper measures impact of Organizational climate on job satisfaction, job commitment and intention to leave with the help of regression analysis and an attempt has been made to see the factor-wise effect of Organizational climate and job satisfaction on job commitment and intention to leave

    Impact of Gd doping on morphology and superconductivity of NbN sputtered thin films

    Full text link
    We report effect of Gd inclusion in the NbN superconductor thin films. The films are deposited on single crystalline Silicon (100) by DC reactive sputtering technique i.e., deposition of Nb and Gd in presence of reactive N2 gas. The fabricated relatively thick films (400 nm) are crystallized in cubic structure. These films are characterized for their morphology, elemental analysis and roughness by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray spectroscopy (EDAX) and Atomic Force Microscopy (AFM) respectively. The optimized film (maximum Tc) is achieved with gas ratio of Ar:N2 (80:20) for both pristine and Gd doped films. The optimized NbN film possesses Tc (R=0) in zero and 140kOe fields are at 14.8K and 8.8K respectively. The Gd doped NbN film showed Tc (R=0) in zero and 130kOe fields at 11.2K and 6.8 K respectively. The upper critical field Hc2(0) of the studied superconducting films is calculated from the magneto-transport [R(T)H] measurements using GL equations. It is found that Gd doping deteriorated the superconducting performance of NbN.Comment: 14 pages Text+Figs: comments/suggestions ([email protected])/www.freewebs.com/vpsawana

    SWEET FUTURE OF STEVIA: A MAGICAL SWEETENER

    Get PDF
      The plant Stevia rebaudiana is mainly found in tropical and subtropical regions from western North America to South America. This genus is having near about 240 species of shrubs and herbs in the sunflower family (Asteraceae). It exhibits various properties such as antibacterial, antifungal, anti-inflammatory, antimicrobial, antiviral, antiyeast, cardiotonic, diuretic, hypoglycemic, hypotensive tonic, and vasodilator effect. It is an important source of a number of antioxidants, for example, benzoic acid, caffeic acid, chlorogenic acid, ferulic acid, rozmaric acid, protocatechuic acid, salicylic acid, and their derivatives and flavonoids including campherol derivatives, catechin, and its derivatives, epicatechin, luteolin, and its derivatives, rutin, and its derivatives. Day by day, there is remarkable increase in demand of high potency sweeteners. The increasing number of diabetic patients and health conscious individuals would push forward the need for alternatives to sugar. The extract from leaves of Stevia is 200 times sweeter than sugar (glucose, fructose, sucrose, maltose, and lactose). Stevia is a potential alternative source for replacing artificial sweeteners such as saccharin, aspartame, and asulfam

    Synergistic effect on static and dynamic mechanical properties of carbon fiber-multiwalled carbon nanotube hybrid polycarbonate composites

    Carbon fiber (CF) and multiwalled carbon nanotube (MWCNT)-reinforced hybrid micro-nanocomposites are prepared through melt mixing followed by injection moulding. The synergistic effect on both the static and dynamic mechanical properties with MWCNT/aMWCNT and CF reinforcement in a polycarbonate matrix is investigated by utilizing dynamic mechanical analysis, and flexural and tensile measurements. The enhancement in the flexural modulus and strength of the composite specimens as compared to pure PC for maximum loading of CF is 128.40% and 39.90%, respectively, which further improved to 142.94% and 42.60%, respectively, for CF-functionalized MWCNTs. Similarly, the storage modulus of the composite specimens reinforced with a maximum loading of CF and CF-functionalized MWCNTs show an increment of 176.57% and 203.33%, respectively over pure PC at 40 degrees C. Various types of parameter such as the coefficient C factor, degree of entanglement and adhesion factor have been calculated to analyze the interaction between fillers and the polymer matrix. Composite specimens containing 2 wt% of functionalized MWCNTs show a lower C value than the as-synthesized MWCNTs, which is indicative of a higher effectiveness of functionalized MWCNT-containing composite specimens. These results are well supported by optical microscopy and Raman spectroscopy by confirming the distribution of reinforcement

    Multiwalled carbon nanotubes (MWCNTs), functionalized carbon nanotubes (FCNTs) and graphene oxide-carbon nanotube (GCNTs) hybrid Bucky paper (BP) reinforced acrylonitrile-butadiene-styrene (ABS) composites are prepared via vacuum filtration followed by hot compression molding. The nanomechanical, electrical and thermal properties of these BP reinforced ABS composites are studied. The nanoindentation hardness and elastic modulus of GCNTs-ABS hybrid composites reached to 389.98 +/- 91.79 MPa and 7669.6 +/- 1179.12 MPa respectively. Other nanomechanical parameters such as plastic index parameter, elastic recovery, the ratio of residual displacement after load removal and displacement at maximum load are also investigated. The improved nanomechanical properties are correlated with Raman spectroscopy and scanning electron microscopy (SEM). It is found that GCNTs and their composites showed the higher value of defect density. The maximum value of defect density range for GCNTs and GCNTs-ABS is (297.4 to 159.6) and (16.0 to11.6), respectively. The higher defect density of GCNTs indicates that the interfacial interaction between the ABS, which was further correlated with electrical and thermal properties. Additionally, the through-plane electrical conductivities of MWCNTs, FCNTs and GCNTs based ABS composites were 6.5 +/- 0.6, 4.5 +/- 0.7 and 6.97 +/- 1.2 S/cm respectively and thermal conductivities of MWCNTs, FCNTs and GCNTs reinforced ABS composites; 1.80, 1.70 and 1.98 W/mK respectively. These GCNTs-ABS composites with this value of thermal conductivity can be used in various applications of efficient heat dissipative materials for electronic devices

    This study evaluates the role of self-efficacy between mentoring and its outcomes namely, relationship quality, communication satisfaction, and personal learning. It also examines the mediating role of relationship quality, communication satisfaction, and personal learning between mentoring and job performance. Besides, this moderated mediation relationship is also evaluated. Data has been collected from 276 employees working in banking sector in Jammu and Kashmir (J&K, India). The confirmatory factor analysis has been done for confirming the factor structure and structural equation modelling for testing the hypothesized relations. Results revealed that self-efficacy moderates the relationship between mentoring and personal learning, relationship quality, and communication satisfaction. Further the study revealed that interaction effect of mentoring and self-efficacy on job performance is mediated by personal learning, relationship quality, and communication satisfaction. The data has been collected using a questionnaire at a single point of time. For future research longitudinal study should be conducted

    The present study focuses on the role of leader–member exchange and relational identification (RI) between transformational leadership and job performance relationship. The model has been tested in higher education sector. All the permanent teachers working in higher education sector were contacted. The data have been duly validated with the help of confirmatory factor analysis (CFA). Reliability has been assessed through Cronbach’s alpha and composite reliability. Structural equation modeling (SEM) has been used for hypotheses testing, and hierarchical regression has been used to test the moderating effect of RI. The results indicated that leader–member exchange acts as a mediator and RI acts as a moderator instead of mediator. The managerial implications and future scope have been discussed
