Green synthesis of silver Nanoparticle using Carica Papaya and study there Biochemical Application
No full textAbstract: The nanopartical offer several advantages over other conventional drug delivery systems. Nanoparticles have gained importance in technological advancements due to their modifiable physical, chemical and biological properties with improved performance over their bulk foils. Nanoparticles can simply move in the body due to their small size and reach very complex organs through divers routes. The high stability, controlled drug release makes nanoparticles the most suitable drug delivery system. The study of different methods of synthesis of nanoparticles is essential to obtain desired nanoparticle with specific sizes and shapes. They are suitable candidates for various marketable and local application, which include imaging, catalysis medical application and environmental application.
Keywords: Nanopartical, bulk foil, divers routes.

A Solution for Mandibular Deviation with Early Restoration of Function and Esthetics: A Case Report
No full textBackground : Prosthetic rehabilitation of the hemimandibulectomy patient has always been a difficult task for the prosthodontist. Mandibular discontinuity following resection is a debilitating condition for patients. Mandibular deviation results in impaired masticatory function and facial disfigurement. Early prosthetic intervention by guide flange prosthesis helps the patient to achieve normal maxillo-mandibular relationship and early restoration of normal function. This case report presents the fabrication of guide flange prosthesis prior to hemimandibulectomy procedure, preventing mandibular deviation
High Energy Planetary Milling Of Fe, Cr & Ni Powder
No full textStainless steel powder is widely used in offshore applications as it has excellent corrosion resistance property. In the present study, high-energy planetary milling of elemental Fe, Cr and Ni powder was carried out for 30 hours to prepare nanostructured stainless steel powder. In one set of experiment Cr: Ni weight ratio was 18:8 (rest Fe) whereas in another set the ratio was 20:10 (rest Fe). Milling was carried out in Toluene at a speed of 300 rpm for 30 hours. The extent of alloying, along with the structural and morphological changes of the occurring in the powder form of nano-material was analyzed and studied using X-ray diffractometer, Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS)

Difficulty of detection makes targeted emailphishing one of the hardest problem to solve. We present a new method to detect email spearphishing attacks using a method that is less taxing on the machine resource as compared toa spam filter which uses machine learning. We have implemented the scheme as a plugin tooutlook and report our performance and effectiveness based on CSDMC2010 SPAM, Enronand Spam Assassin dataset with a total of 25,834 spam emails and 41,320 ham emails
Mechanism and performance evaluation of spent-coffee grounds-derived nanocomposite materials for highly efficient photocatalytic degradation of organic pollutant
No full textThe study demonstrates a facile and environmentally friendly method for synthesizing crystalline TiO2 nanoparticles on the surface of hydrochar generated from readily available biomass waste, i.e., spent coffee grounds (SCGs), using a simple sol–gel process. The hydrochar served as a support for TiO2, reducing the rate at which electrons and holes recombine during photocatalysis, thereby facilitating the effective binding of TiO2, enhancing its adsorption capacity, and the convenient separation of the photocatalyst after usage. The materials were tested in the photocatalytic degradation of an organic pollutant, methylene blue (MB) dye. TiO2-hydrochar obtained at 210 ⁰C has the best performance, giving a degradation efficiency of 98.5 % and a mineralization efficiency of 87.1 % in 90 min at neutral pH. Radical trapping experiments showed
being the dominant species, followed by
. Besides, it showed superior stability with an activity loss of ∼ 9.2 % after five runs. The superior performance of the HCT210 was ascribed to the enhanced interfacial charge transfer kinetics between the TiO2 and hydrochar through
bond formation, better light absorption, and the high surface area of the materials. Performance metrics show that synthesized nanocomposites are promising photocatalysts, providing a biomass-assisted method for robust photocatalytic wastewater treatment.Killam TrustsNatural Science and Engineering Research Council (NSERC
Hydrothermal carbonization of sawdust for hydrochar production to prepare solid fuels
No full textHydrothermal carbonization (HTC) of sawdust for producing hydrochar was optimized using response surface methodology (RSM). After optimization, the combustion behaviour and other relevant fuel properties of hydrochar that was obtained at the optimized conditions were studied. Additionally, the aqueous phase obtained at the optimized conditions was recycled as the reaction medium for producing hydrochar and the influence of the aqueous phase recycling on the hydrochar yield and properties was evaluated. The results indicated that the highest hydrochar yield of 84.23 wt.% under the predicted optimum conditions of temperature of 162.23°C, 2.51 h, feedstock loading of 10.71 wt.%, and catalyst loading of 7.99 wt.%. Furthermore, it was found that the use of recycled aqueous phase as the reaction medium led to an increase in the hydrochar yield, higher heating value (HHV), and energy yield, and difference in combustion behaviour was minor. Overall, this study filled the gap in HTC literature regarding the effect of catalyst on hydrochar production and provided a practical solution to treat the aqueous phase
Heuristics2Annotate: Efficient Annotation of Large-Scale Marathon Dataset For Bounding Box Regression
No full textAnnotating a large-scale in-the-wild person re-identification dataset especially of marathon runners is a challenging task. The variations in the scenarios such as camera viewpoints, resolution, occlusion, and illumination make the problem non-trivial. Manually annotating bounding boxes in such large-scale datasets is cost-inefficient. Additionally, due to crowdedness and occlusion in the videos, aligning the identity of runners across multiple disjoint cameras is a challenge. We collected a novel large-scale in-the-wild video dataset of marathon runners. The dataset consists of hours of recording of thousands of runners captured using 42 hand-held smartphone cameras and covering real-world scenarios. Due to the presence of crowdedness and occlusion in the videos, the annotation of runners becomes a challenging task. We propose a new scheme for tackling the challenges in the annotation of such large dataset. Our technique reduces the overall cost of annotation in terms of time as well as budget. We demonstrate performing fps analysis to reduce the effort and time of annotation. We investigate several annotation methods for efficiently generating tight bounding boxes. Our results prove that interpolating bounding boxes between keyframes is the most efficient method of bounding box generation amongst several other methods and is 3x times faster than the naive baseline method. We introduce a novel way of aligning the identity of runners in disjoint cameras. Our inter-camera alignment tool integrated with the state-of-the-art person re-id system proves to be sufficient and effective in the alignment of the runners across multiple cameras with non-overlapping views. Our proposed framework of annotation reduces the annotation cost of the dataset by a factor of 16x, also effectively aligning 93.64\% of the runners in the cross-camera setting
