Observation of Mixed Alkali Like Behaviour by Fluorine Ion in Mixed Alkali Oxyfluro Vanadate Glasses: Analysis from Conductivity Measurements

In this communication we report the fluorine ion dynamics in mixed alkali oxyfluro vanadate glasses. We have measured the electrical conductivity using impedance spectroscopy technique Room temperature conductivity falls to 5 orders of magnitude from its single alkali values at 33 mol% of rubidium concentration. We have also estimated the distance between similar mobile ions using the density values. Assuming this distance as the hopping distance between the similar ions we have estimated the anionic (Fluorine ion in our case) conductivity. It is observed that the fluorine ion dynamics mimics the mixed alkali effect and scales as the onset frequency f0.Comment: submitted to DAE-SSDP 2018 Indi

Graphical Password Scheme Resistant to Shoulder Surfing

We propose another graphical secret key plan. It is characterized as test reaction distinguishing proof. Henceforth, a secret word in our plan is time-variation. Client who knows the secret key can meet the test and to react effectively. As a result, our graphical secret key plan is shoulder-surfing safe. An assailant still can't tell what the secret key is, regardless of the possibility that he/she has taped a client's login procedure. Essential investigations on our graphical secret key plan demonstrated the plan is promising

Analysis and advanced characterization of municipal solid waste vermicompost maturity for a green environment

Rapid demographic expansion along with increasing urbanization has aggravated the problem of solid waste management. Therefore, scientists are seeking waste management methods that are eco-friendly, cost effective and produce immediate results. In the developing world, municipal solid waste (MSW) contains mostly organic substances, therefore vermicomposting could be a better and cost-effective option for waste management. In this study, vermicomposting of organic portion of MSW with cow dung (additive) was performed using Eisenia fetida. The results showed significant (p < 0.001) decline in pH (13.17%), TOC (21.70%), C: N (62.53%) and C: P (57.66%) ratios, whilst total N (108.9%), P (84.89%) and K (21.85%) content increased (p < 0.001) in matured vermicompost. Different enzymatic activities declined during termination phase of vermicomposting experiment with maximum decrease of 41.72 (p = 0.002) and 39.56% (p = 0.001) in protease and β-glucosidase, respectively. FT-IR, TGA, DSC and SEM studies suggested that final vermicompost was more stabilized as compared to initial waste mixture, characterized by reduced levels of aliphatic materials, carbohydrates and increase in aromatic groups possibly due to biosynthesis of humic substances. Both, the conventional (physicochemical and enzyme activity) and advanced techniques depict maturity and stability of the ready vermicompost. However, FT-IR, TGA, DSC and SEM were proved to be more promising, fast and reliable techniques over conventional analyses

Market-Driven Innovation

A new method for starting the iterative innovation process from the market side based on a sociological trend has been developed. It eliminates the traditional difference between the innovators and the sociological group that carries this trend, which can only be achieved by combining real-world innovation with innovation education. The method for market need discovery is presented as a step-by-step process with detailed reasoning, followed by a real-world example that details the outcomes at every step along the way. The example concludes with a detailed description of the outcome after the first innovation iteration cycle. The richness of the resulting concept demonstrates that an innovation process can be successfully started from the market side via the proposed method

Deceased-Donor renal transplantation: A single-center experience from a tertiary care hospital in North India

Introduction: Deceased-donor renal transplants can help cope up with the increasing demand of renal allografts in India. We evaluated the outcomes of deceased-donor renal transplantation at our center. Methods: This retrospective study analyzed the donor and recipient characteristics along with graft and patient survival in deceased-donor renal transplant recipients at our center between April 2011 and October 2021. Results: The mean age of recipients (n = 21) and deceased donors was 48 ± 9.4 and 39.3 ± 8.7 years, respectively. Male:female ratio among recipients was 1.6:1 while that in donors was 2:1. Chronic glomerulonephritis (71.4%) was the most common native kidney disease. Most patients received antithymocyte globulin (80.9%) as induction and tacrolimus-based triple-drug regimen (80.4%) as maintenance therapy. The median follow-up duration was 32.8 months. Graft dysfunction was reported in 57.1% (n = 12/21) patients; acute tubular necrosis was the most common reason (n = 5). Six patients died, and sepsis was the most common reason for death (n = 3/6; 50%); 66.7% (n = 4/6) deaths occurred within the first 6 months. The mean graft survival time was 106.2 months (95% confidence interval: 95.4–116.6). The cumulative proportion of graft survival was 95.2% (n = 20/21) at 3 and 5 years. The cumulative proportion of patient survival was 80.9% at 3 years and 76.2% at 5 years. Conclusion: Patient outcomes over 5 years follow-up were good and suggest that deceased-donor transplants should be encouraged along with living-donor transplants to cover the huge demand–supply mismatch in renal replacement therapy
