First principles calculations of structural, electronic, mechanical, and thermodynamic properties of different poly- morphs of BiVO4 are performed using Bender-type plane/wave ultrasoft pseudopotentials within the generalized gradient approximation （GGA） in the flame of density functional theory （DFT）. The calculated structural and electronic properties are consistent with the previous theoretical and experimental results. The electronic structures reveal that m-BiVO4, op- BiVO4, and st-BiVO4 have indirect band gaps, on the other hand, zt-BiVO4 has a direct band gap. From the DOS and Mulliken＇s charge analysis, it is observed that only m-BiVO4 has 6s2 Bi lone pair. Bond population analysis indicates that st-BiVO4 shows a more ionic nature and a similar result is obtained from the elastic properties. From the elastic prop- erties, it is observed that st-BiVO4 is more mechanically stable than the others, st-BiVO4 is more ductile and useful for high electro-optical and electro-mechanical coupling devices. Our calculated thermodynamic properties confirm the similar characteristics found from electronic and elastic properties, m-BiVO4 is useful as photocatalysts, solid state electrolyte, and electrode and other polymorphs are applicable in electronic device fabrications.

An important and challenging aspect of developing an intelligent transportation system is the identification of nighttime vehicles. Most accidents occur at night owing to the absence of night lighting conditions. Vehicle detection has become a vital subject for research to ensure safety and avoid accidents. New vision-based on-road nighttime vehicle detection and tracking system are suggested in this survey paper using taillight and headlight features. Using computer vision and some image processing techniques, the proposed system can identify vehicles based on taillight and headlight features. For vehicle tracking, a centroid tracking algorithm has been used. Euclidean Distance method has been used for measuring the distances between two neighboring objects and tracks the nearest neighbor. In the proposed system two flexible fixed Region of Interest (ROI) have been used, one is the Headlight ROI, and another is the Taillight ROI that could adapt to different resolutions of the images and videos. The achievement of this research work is that the proposed two ROIs can work simultaneously in a frame to identify oncoming and preceding vehicles at night. The segmentation techniques and double thresholding method have been used to extract the red and white components from the scene to identify the vehicle headlights and taillights. To evaluate the capability of the proposed process, two types of datasets have been used. Experimental findings indicate that the performance of the proposed technique is reliable and effective in distinct nighttime environments for detection and tracking of vehicles. The proposed method has been able to detect and track double lights as well as single light such as motorcycle light and achieved average accuracy and average processing time of vehicle detection about 97.22% and 0.01 s per frame respectively.

Conventional growth media for microbes contains lots of non-edible components that are harmful to consume when the organism is ready to intake—like probiotics growing in chemical media (Lactobacillus grown in MRS media). The study was conducted to develop an edible and low-cost growth media that supports the growth of probiotics Lactic Acid bacteria for the enhancement of probiotic research. The 04 isolates of Lactobacillus (L. plantarum, L. rhamnosus, L. ferciminis and L. bifarmentans) and 02 Bifidobacterium (B. infantis and B. Bifidum) were used for the evaluation of medium efficacy. To formulate the edible culture media, 04 vegetables and 02 pulses were used. The media was formulated in different formulations. For Lactobacillus, maximum growth was observed at MM-2 media formulation that was about 15.62 log CFU/ml for L. plantarum and compared to MRS media that was 11.78 log CFU/ml. Bifidobaterium showed the highest viability at MW-1 edible media formulation which was about 12.72 log CFU/ml whereas in Bifidobacteria selective media the cell viability was 12.48 log CFU/ml. The edible media has no toxic or unhealthy effect on mice while trailing in an animal model and shows excellent results in encapsulation with alginate. In comparison with the performance of traditional chemical media, the formulated media were found to be cost-effective and safe for human consumption.

The main purpose of the study was to reveal the hypoglycemic effect of a combination of some selected spices along with the evaluation of nutritional values. A sum of fourteen different types of spices at different percentages were taken into consideration to propel the research activities forward, viz;ginger, garlic, onion, red chili, turmeric, cumin, cinnamon, clove, coriander, fenugreek, black pepper, nigella, carom seed and cardamom. The healthy experimental wistar albino rats were made diabetic by injecting alloxan monohydrate intraperitoneally a dose of 150 mg/kg body weight. The rats of Group-D and Group-E were treated with the sample, mixed spices at a dose of 100 mg/kg and 200 mg/kg body weight respectively with the lab diet while in case of Group-C, glibenclamide at a dose of 0.5 mg/kg body weight was introduced with the lab diet for a total period of 21 days where as for the same days span, Group-A and Group-B were continued feeding with only lab diet. Data suggest that the mixed spices of both doses applied in Group-D and Group-E had exerted effects significantly (p 0.05) in lowering the blood glucose level. On 22nd day, in Group-D and Group-E, the FBG level was found to be reduced by around 40.66% and 41.18% respectively compared to their respective initial days where in Group-C, the reduction was around 51.90% in comparison to its initial day. Again, in case of 2hPG level measurement, on 22nd day, both the groups, Group-D and Group-E were found with the decreased level of around 19.38% and 39.11% respectively compared to their respective initial days while the Group-C was shown with the reduced of 44.26% in comparison adopting same manner. Furthermore, various analyses confirm the presence of several micro and macro nutrients and high amount of dietary fiber in the spices mix. Thus the result affirms that this combined spice possesses strong hypoglycemic properties.

The study was carried out to evaluate the hypolipidemic and hypoglycemic effect of Nelumbo nucifera leaf powder. In rats, hyperlipidemia was induced by feeding High Fat Diet (Lab diet: Dalda: Coconut oil = 4:3:1) and type 2 diabetes was built inside by injecting Alloxan. The sample N. nucifera leaf powder was added in different percentages with the regular Lab Diet for 21 days feeding. In case of hyperlipidemia developed groups, feeding of Nelumbo nucifera leaf powder at, 30% (70% Lab diet + 30% Sample), 20% (80% Lab diet + 20% Sample) and 10% (90% Lab diet + 10% Sample) showed varied but in a nutshell significant (p Nelumbo nucifera leaf powder for 21 days resulted significant decrease in the blood glucose levels of alloxan-induced diabetic rats. Both the percentages of Nelumbo nucifera leaf powder having 20% with 80% Lab Diet and 10% with 90% Lab Diet significantly (p Nelumbo nucifera powder was found to be exerted to the more prominent effects in lowering the blood glucose level. Nelumbo nucifera leaf powder had 75% efficacy rate in lowering the blood glucose level in comparison to the drug control group treated with glibenclamide which was found with the decreasing capability up to 66%. Although not significant, it, based on the data, can be stated that the sample is endowed with the quality of decreasing capability of body weight. Thus, results of the experimental study reveal that the leaf of Nelumbo nucifera has potent hypoglycemic and hypolipidemic properties.
