The modern critical analysis of Bose–Einstein and Fermi–Dirac statistics is proposed. Methodological basis of analysis is the unity of formal logic and rational dialectics. It is shown that Bose–Einstein and Fermi–Dirac statistics – as consequence of Bose's erroneous method – contain logical errors. The main error is that Bose–Einstein and Fermi–Dirac distribution functions contain chemical potential. It is proved that chemical potential is identically equal to zero because the concept of chemical potential is contrary to the concept of temperature. There exist the only one correct statistics in statistical physics: Gibbs statistics.

The Photocatalytic process is one of the important green engineering concepts employed for treating the waste water from industries. This paper presents an overview of Photocatalytic degradation of textile effluents in industries by titania (TiO2). TiO2nanocatalystwas synthesized using sonochemical method. This Nanocatalyst was characterized using SEM, XRD &TGA. An Effluent from the textile contains hazardous compounds such as ethyl sulphonic and sulphonic groups which cause severe water pollution. Photocatalytic degradation using Tio2nanophotocatalyst based adsorbent as a semiconductor in a batch reactor. Experiments were performed to observe the extent of photocatalytic degradation of textile effluents by analyzing different parameters. The effluents were degraded and nearly 96% of colour reduction was observed. Experiments were also conducted to optimize the amount of catalyst used during this process. This process is a very effective green engineering concept and a cheapest for treating the textile effluents using TiO2 before disposing it off into water.

Chickpea grain damage in various forms, in which splitting is more important than other aspects, because of quantitative losses. This paper investigates the mechanical strength of chickpea kernels in relation to splitting. In this relation, three varieties (Bivanij, ILC482 and Philip 93-93) of chickpea at three levels of moisture content (15.5, 20.8 and 25.6 % wet bases) and three loading orientations (Length, Width and Thickness of kernel) were tested under quasi-static uni-axial compression. Measured and calculated parameters were including rupture force, maximum strain and deformation, rupture energy, maximum normal contact stress and apparent modulus of elasticity. Moisture content had a considerable effect on all mechanical parameters. In addition, the results showed that values of chickpea strength properties were lowest when loaded in the length direction. The minimum values of modulus of elasticity and rupture energy were equal to 6.75 MPa and 43.28 mJ, respectively, at 26%(w.b.). According to statistical results, Philip 93-93 variety had the highest resistance to damage and splitting in comparison to two other varieties. Several linear and nonlinear models were developed for prediction of chickpea strength parameters that presented in the article.

Introduction: 103Pd brachytherapy sources are used normally in prostate and breast cancer therapy. For calculating the effect of source shield or applicators and dose distribution usually Monte Carlo codes such as MCNP and GEANT are applied. The aim of this work is to determine the dosimetric parameters of a 103Pd source in soft tissue phantom. Method: In this present work, we have used MCNP4C code to calculate relative dose in soft tissue phantom. We have calculated the dose distribution in soft tissue phantom with 1.04 g/cm3 density which is more accurate than water phantom for human tissue. Results: We have determined the isodose curves and anisotropy function, F(r,?), and radial dose function, g(r), which are important dosimetric parameters. Our result are in good agreement with others result. Conclusion: Dose deposition in high gradient region, near the source, can only be calculated accurately by Monte Carlo method. The obtained value of g(r) and F(1 cm, ?) as the TG-43 parameters for the source, are agree quite well with the result of others.

There is a paradigm shift among the digital learners of 21st century due to the rapid increase in the usage of gadgets, such as computers, mobile phones, social networking sites, blogs and etc. Among International Baccalaureate teachers today, use of gadgets is widely used to engage their students and in the process, try to use technology tools such as Web 2.0 for collaborative projects, connecting participants beyond the traditional classrooms. This paper explores on digital literacy in the context of IB World School students learning engagement, using technology. As such, an implementation of Wikispaces Classroom for 6 weeks in an Information Technology Communication and Visual Arts lesson was used to capture their digital literacy in a Grade 5 classroom. The outcome of the research encapsulates the students’ perceptions towards their new learning experience through Web tools: Wikispaces Classroom for Visual Arts. As a result, student’s engagement in learning Visual Arts has increased and learning has generated knowledge in Visual Arts and other subject areas. This paper recommends digital literacy tools engage students in learning, which impact curriculum design and planning for future. 

Since the inception of knowledge research has been playing a pivotal role in the discovery of new vistas of knowledge. Therefore, the teachers, researchers, and theorists staunchly believe that educational research and teaching is essentially interlinked. Research is systematic and within a broad framework follows the steps known as scientific method. However, across different types of studies there is extensive flexibility in how the steps are implemented. a research should be systematic , empirical valid and reliable in its nature. Various kinds of research are used by researchers by the researchers in accordance to their needs of specific research design. The review of the literature revealed that research has played an important role in the development of theory, learning theories and curriculum. The use of these theories and curriculum helped the theorists to design teaching models which are now used by the teachers to impart knowledge effectively. The historical research method was used for this study because this study aimed at having a review of literature related to research-based teaching learning process. The study has revealed that effective teaching is possible only when teachers possess ample knowledge of philosophy, learning theories, curriculum and strategies of teaching. Having been acquainted with these fundamentals of research and knowledge a teacher would be professional and effective teacher who would disseminate knowledge in a professional manner.

A dusty plasma system containing non-thermal ion distributions, Boltzmann-distributed electrons and mobile charge fluctuating positive dust has been considered. The nonlinear propagation of the dust-acoustic (DA) waves in such dusty plasma has been investigated by employing the reductive perturbation method to derive the Burgers equation. The effect of non-thermal ions on the height and thickness of DA shock waves are also studied.

Workforce diversity and employees commitment in the context of Globalization has attained significant attention of today’s Researchers. This paper endeavors to ascertain major factors of work-setting and its effects on organizational performance. Two independent variables i.e workforce diversity and committed workforce relations have been analyzed on employee’s organizational performance. Data was collected from 286 respondents from employee’s belonging to the corporate sector of Islamabad Pakistan. Middle level management tiers were segment of the study age ranging from 30 to 40 years. Questionnaire was administered using five point likert scale. Result reveals that there is 71% variation between committed work force and organizational performance: henceforth, that committed work force is an important factor of organizational growth with a t-value of (17.295). The p values indicates that the variables are significant as P<.05. Similarly, committed work force effects have variation on organizational performance by 20 %. The results further represent that the variables are significant with the p value of <.05). It is evident from the analysis that diverse workforce oncemanaged well on the work environment and employee’s are committed then organizational performance is with t-value of 6.679. It is therefore imperative for the organizations to accord due priority to the major work-setting like diversity and employee commitment in the organizations facilitating employees to yield befitting organizational loyalty.
