The extinction model studied in this analysis is motivated by the search for signatures of strong gravity at the TeV scale (terascale gravity) and assumes the existence of string couplings in the strong-coupling limit. In this limit, the string model predicts the suppression of all high-transverse-momentum standard model processes, including jet production, beyond a certain energy scale. To test this prediction, the measured transverse-momentum spectrum is compared to the theoretical prediction of the standard model. No significant deficit of events is found at high transverse momentum. A 95% confidence level lower limit of 3.3 TeV is set on the extinction mass scale

Effect of organizational climate upon the job performance of instructors’ physical education

Propose: The current study was conducted to examine the effect of organizational climate on the Job Performance of Instructors’ Physical Education. Material: A quantitative method was employed for this purpose; a survey research design was used. There was 169 Instructors’ Physical Education preferred through stratified sampling technique. A structured questionnaire was administered to collect the data. The data was analyzed using inferential statistics (linear and multiple regression). Results: The results of the study indicated that organizational climate affect job satisfaction significantly. All the dimensions of organizational climate contribute to increasing the Instructors’ Physical Education performance. Conclusion: The current study concluded that Instructors’ Physical Education not only feel comfortable in a healthy organizational climate but also increase their level of performance. The study also depicted that effective communication structure, reward system, teamwork, career development, and effective planning and decision making strategies are the valuable ingredients to enhance the performance of Instructors’ Physical Education. Recommendation: Keeping in view the results of the current study, it is recommended that head of the institution may focus or promote supportive culture in their respective educational institutions to enhance the performance of instructors’ physical education

Effect of Zn Doping on Structural and Magnetic Properties of Ba4Ni2-xZnxFe36O60 Hexaferrites

Polycrystalline Ba4Ni2−xZnxFe36O60 (0.0 ≤x ≤ 1.4) hexagonal ferrite samples have been prepared by conventional solid-state reaction method. Structural and magnetic properties of the prepared samples were then analyzed by the X-ray diffraction techn

Using integrating spheres with wavelength modulation spectroscopy: effect of pathlength distribution on 2nd harmonic signals

We have studied the effect on 2nd harmonic wavelength modulation spectroscopy of the use of integrating spheres as multipass gas cells. The gas lineshape becomes distorted at high concentrations, as a consequence of the exponential pathlength distribution of the sphere, introducing nonlinearity beyond that expected from the Beer-Lambert law. We have modelled this numerically for methane absorption at 1.651μm, with gas concentrations in the range of 0-2.5%vol in air. The results of this model compare well with experimental measurements. The nonlinearity for the 2f WMS measurements is larger than that for direct scan measurements; if this additional effect were not accounted for, the resulting error would be approximately 20% of the reading at a concentration of 2.5 %vol methane
