Comparative experimental and Density Functional Theory (DFT) study of the physical properties of MgB2 and AlB2

In present study, we report an inter-comparison of various physical and electronic properties of MgB2 and AlB2. Interestingly, the sign of S(T) is +ve for MgB2 the same is -ve for AlB2. This is consistent our band structure plots. We fitted the experimental specific heat of MgB2 to Debye Einstein model and estimated the value of Debye temperature (theta) and Sommerfeld constant (gamma) for electronic specific heat. Further, from gamma the electronic density of states (DOS) at Fermi level N(EF) is calculated. From the ratio of experimental N (EF) and the one being calculated from DFT, we obtained value of Lembda to be 1.84, thus placing MgB2 in the strong coupling BCS category. The electronic specific heat of MgB2 is also fitted below Tc using pi-model and found that it is a two gap superconductor. The calculated values of two gaps are in good agreement with earlier reports. Our results clearly demonstrate that the superconductivity of MgB2 is due to very large phonon contribution from its stretched lattice. The same two effects are obviously missing in AlB2 and hence it is not superconducting. DFT calculations demonstrated that for MgB2 the majority of states come from Sigma and Pi 2p states of boron on the other hand Sigma band at Fermi level for AlB2 is absent. This leads to a weak electron phonon coupling and also to hole deficiency as Pi bands are known to be of electron type and hence obviously the AlB2 is not superconducting. The DFT calculations are consistent with the measured physical properties of the studied borides, i.e., MgB2 and AlB2Comment: 16 pages Text + Figs: comments/suggestions welcome ([email protected])/www.freewebs.com/vpsawana

Effect of Ambient Temperature on Calibration of Cooled Thermal Camera

Thermal cameras may be used under ambient conditions that differ significantly from the calibration conditions. The effect of ambient temperature on temperature measurement error is examined for MWIR and LWIR cooled thermal cameras. The facilities used include an environmental chamber and an extended area blackbody with temperature controller. Significant differences were observed in the temperatures measured by the cameras placed in different ambient temperatures, with reference to the set blackbody temperatures. Re-calibration was done to account for variations in ambient temperature from 5 ºC to on the outputs of the cameras. It was found that after such recalibration, the measurement error was within acceptable accuracy of ±1 °C

Estimation of Effect of Emissivity on Target Detection through Thermal Imaging Systems

The effects of target emissivity on apparent thermal contrast as well as on detection range capabilities of thermal imagers in long wave infrared and middle wave infrared bands were evaluated. The apparent thermal contrast (to be seen by the thermal imager at standoff distance), considering only the emission from target and background, was first computed in both the IR bands in terms of target emissivity and secondly the apparent thermal contrast, considering the background radiation reflected off the target, was also computed. A graphical user interface simulation in MATLAB was prepared for the estimation of total apparent thermal contrast taking into account both the emission and reflection. This total apparent thermal contrast was finally used in night vision thermal and image processing model for predicting the detection range performance of thermal imagers. Results of the analysis show that the effect of target emissivity on thermal contrast estimates is more pronounced in LWIR. The lower thermodynamic temperature difference between target and background at lower values of target emissivity leads to negative thermal contrast which in-turn leads to higher detection ranges

A Rare Case of Primary Anterior Chest Wall Abscess due to Salmonella Typhi in an Immunocompetent Male

A case of suspicious anterior chest wall mass due to Salmonella enterica serotype Typhi in a middle aged, non- diabetic male is being described. The infection was successfully treated with timely institution of antibiotic treatment. This case highlights the fact that a focal Salmonella infection involving the anteriorchest wall should be considered as a differential diagnosis and not treated as tuberculosis empirically. Submission of specimens for microbiological analysis should be performed for an accurate diagnosis and management

A Study of Climate Variability and Socioeconomic Impact on Tourism Industry of Nepal

In Nepal, tourism is the second largest industry after agriculture. Furthermore, Nepal offers numerous opportunities for adventurous outdoor recreation, especially in the Himalayas, and attracts touristsfrom all over the World. However, future prosperity of Nepal’s tourism industry might be affected by a changing climate and a socioeconomic environment. A log-level regression model is employed to estimate the impact of climatic and socioeconomic factors on the number of international tourists visiting Nepal. Climatic estimates indicated that an increase in temperature did not have a significant impact on the numbers of international tourist arrival. Results show that the number of international tourists visiting Nepal was positively associated with GDP and population growth, inflation rate, and an exchange rate. These results help policy makers for facilitating growth of tourism industry and its adaptability to climate change in Nepal

Demand and Supply of Forest Products in Bandevi Buffer Zone Community Forest, Chitwan National Park, Nepal

Buffer Zone Community Forestry (BZCF) in the Chitwan National Park (CNP) started with an objective to engage locals and fulfill their resource needs without jeopardizing conservation. This study estimates the forest product demand and supply of fuelwood, fodder, and timber in Bandevi BZCF user group. Data was collected using stratified random sampling and forest inventory using the quadrate method. Results indicated Bandevi BZCF conditions improved since its handover to the community. However, the study estimated a deficit of 26173 cubic meters per year of timber, 3.21 million tonnes per year (Mt/yr) of fodder, and 0.12 Mt/yr of fuelwood. Deficits were fulfilled from agricultural lands outside BZCF and illegal collection from the Bharandavar corridor forest and CNP. BZCF program is a success in improving forest conditions and needs continuation. Policy and programs must focus primarily on livelihood improvement and income generations to reduce the dependency of local people on the forest
