Independent t-test and chi-squared test were used to test associations. Correlation between attitude and knowledge on OSH was computed. Results: The response rate was 64.42% (67 laboratory workers). The overall level of knowledge on OSH was moderate, with a mean score of 62%. A larger proportion of female respondents (51.5%) showed good OSH knowledge compared to male respondents (14.7%) and the difference was statistically significant (10.288, 1; p<0.01). Majority of the respondents (73.7%) who worked in a poor OSH laboratory environment had poor attitude level towards OSH (χ2=7.135, df=1; p=0.008). There was a moderate positive correlation between knowledge and attitude on OSH (r=0.4, p<0.01). Knowledge explains 16% of the variance in level of attitude towards OSH among laboratory workers. Conclusion: Knowledge of OSH among laboratory workers was moderate and is associated with gender and OSH environment in the workplace. A greater effort to promote OSH knowledge among the laboratory workers is needed to ensure their safety and health in workplace.

Among our results, we shall show that the generalized free products and HNN extensions where the amalgamated or associated subgroups are finite, or central, or infinite cyclic, or they are direct products of an infinite cyclic subgroup with a finite subgroup, or they are finite extensions of central subgroups, are again cyclic subgroup separable or weakly potent respectively. In order to prove our results, we shall prove a criterion each for the weak potency of generalized free products and HNN extensions, but we shall use previously established criterions for cyclic subgroup separability. Finally, we shall extend our results to tree products and fundamental groups of graphs of groups.

The production of imitating pearl makes user muddled by too much same-looking items. Fast and reliable technique is demanded to distinguish between imitate and original ones. The objective of this study is being able to differentiate between natural pearl and plastic pearl using laser ablation technique. High energy Nd:YAG laser pulse was focused on those samples and evaporise samples in form of plasma plume. Upon deexcitation of the excited electron, electromagnetic radiation which was not being absorbed by the plasma itself was emitted throughout the space and create small crater on samples. The light emission from the plasma was collected through spectrometer and analyzed carefully. The elemental mapping was being carried by matching the central peak of emission lines with standard one. Plotting of optical emission spectrum recorded easily distinguish between original an...

In this paper, we shall show that these groups are still weakly potent when the amalgamated infinite cyclic edge subgroups have trivial intersection.

The model incorporates two-body and more collision effects throughout Carbon plasma using continuity equation. The carbon gas inter electrode gap is accelerated by the electric field to produce plasma. In this model the reaction processes of carbon species is identified. The extrapolation of species dominant in arc discharge process is critical issue in significant for predicting carbon nanostructure production. In this paper, we describe chemical kinetic models and their possibilities of carbon ion and neutral species production based on collisions and time dependence. The results show the reaction rate of Carbon ions calculated at 7.85 × 1028 m-3 s-1 while the temperature increment decreases, the reaction rate is up to 6.25 × 1027 m-3 s-1. The electron density reduces until 108 m-3 from initial condition at 1 atm. However, the electron density increases 1013 m-3 from 0.05 eV-0.3 eV. The ionization of Carbon reaction has been affected by pressure and temperature which gains a quantitative understanding of the density at equilibrium state.

The Split-Step Method has used for numerical calculation to form soliton pulse model. The change in pulse shape and variation in power level have been observed with the increase in the soliton pulse order number. Thus, the soliton pulse parameters can be optimized to acquire the desired output. The dispersion of the pulse is ascertained for observing the pulse compression phenomena.

The Split-Step Method has used for numerical calculation. The change in pulse shape, the slight decrease in power level and dispersion has been observed with increase in the soliton pulse order number. Thus, the soliton pulse parameters can be optimized to acquire the desired output. By using a half-soliton period length of low-loss single-mode fiber, we have been able to demonstrate the pulse compression and pulse splitting associated with several higher-order soliton as well as to observe the fundamental soliton.

Participants were 5,195 employees from 730 teams in 6 Italian local health organizations. Two competing conceptual models were tested for goodness of fit using multilevel path analysis. In the first model, psychological empowerment predicts organizational identification, which, in turn, predicts focal outcomes. In the second model, organizational identification predicts psychological empowerment, which, in turn, predicts focal outcomes. Fit indices of the path analysis indicated that the second model obtained the best fit to the data as compared with other models. Moreover, mediation analysis showed that psychological empowerment mediated the relationship between organizational identification and focal outcomes.

It is essential to account for the velocity distribution of each carbon ion species to determine the greatest contribution from the kinetic energy possesses by each species that govern the binding energy for carbon formation. The resultant speed of the particle as a result of collisions determines the resultant force exerted by the particles which consider in non-conservative force. The variation of velocity distribution is investigated while the reaction rate for carbon species during kinematic process, the transient condition for carbon species is analyzed. Collision rate of carbon ion species is underway to derive carbon ion motion in electrode gap region where the external electric field is constant. The theoretical development has shown that at constant pressure and temperature, carbon ion species possess the resultant speed due to collision frequ...
