Analysis of International Policies In The Solar Electricity Sector: Lessons for India

Although solar costs are dropping rapidly, solar power is still more expensive than conventional and other renewable energy options. The solar sector still needs continuing government policy support. These policies are driven by objectives that go beyond the goal of achieving grid parity. The need to achieve multiple objectives and ensure sufficient political support for solar power makes it diffi cult for policy makers to design the optimal solar power policy. The dynamic and uncertain nature of the solar industry, combined with the constraints offered by broader economic, political and social conditions further complicates the task of policy making. This report presents an analysis of solar promotion policies in seven countries - Germany, Spain, the United States, Japan, China, Taiwan, and India - in terms of their outlook, objectives, policy mechanisms and outcomes. The report presents key insights, primarily in qualitative terms, and recommendations for two distinct audiences. The first audience consists of global policy makers who are exploring various mechanisms to increase the penetration of solar power in markets to mitigate climate change. The second audience consists of key Indian policy makers who are developing a long-term implementation plan under the Jawaharlal Nehru National Solar Mission and various state initiatives

NOVEL DELIVERY APPROACHES OF CO-TRIMOXAZOLE FOR RECREATING ITS POTENTIAL USE-A REVIEW

Co-trimoxazole appropriates to category of broad-spectrum antimicrobial. They are active upon administration in vitro against an extensive collection of microorganisms. Their application in medical field has roughly spanned over decade now. There are numerous approaches that were progressed for improving their effectiveness towards their antimicrobial potency. However, routine use of this could accelerate the chance of bacterial resistance, and portrait it ineffective when required to treat infection. Consequently, newer investigations are necessary to keep the drug effective by minimise the development of resistance and maximise its safe use. Safe use is meant by safe delivery of drug in low dose, low frequency at the targeted molecule by effective ways. This can be achieved by using nanocarrier systems as they possess smart characteristics of effective drug delivery. These nanocarrier systems are including nanoparticle, liposomes, nanogels etc. Present review article deals with the historical perspectives with regards to co-trimoxazole, their mechanism of act/resistance and spectrum of activity in first section. In second portion different novel carriers, importance and application of nanogels, rational for co-trimoxazole nanogels are discussed. In conclusion, different literatures have proved the efficacy of nanogels in delivery of antimicrobial drug similar to co-trimoxazole. In the present time very less data is available for delivery of this drug with novel carriers. Therefore, this review aims to encourage researchers for creating some new findings in this perspective

Correlation between Maternal Mid Upper Arm Circumference and Neonatal Birth Weight: A Case-control Study

Introduction: Birth weight is the best marker of optimal foetal growth and development. Apart from being an important determinant of newborn survival, Low Birth Weight (LBW) also indicates nutritional deprivation and poor health of the mother during and before pregnancy. On the other hand, Maternal nutrition and anthropometry also affect infant’s birth weight. Aim: To find out the correlation of maternal Mid Upper Arm Circumference (MUAC) and neonatal birth weight. Materials and Methods: This case-control study was conducted at Datta Meghe Medical College and Shalinitai Meghe Hospital and Research Centre (tertiary care hospital), Nagpur, Maharashtra, India, from September 2021 to February 2022. Convenient sampling method was used to select cases and control. All the mothers who had delivered full term live singleton new born with birth weight <2.5 kg were selected as a case and mothers who had delivered singleton new born babies ≥2.5 kg were selected as a control. There was a total of 100 mother-infant dyads with 50 pairs having infant with LBW (cases) and the rest 50 with infants having normal birth weight (controls). Data was collected on the socio-demographic status of the mothers using a predesigned questionnaire along with their weight (from record), maternal MUAC measurement, and birth weight of their babies. Analysis was done using Statistical Package for Social Sciences (SPSS) version 16.0. Results: Mean age of cases was 24.48±2.757 years and that of controls was 24.52±2.255 years. Mean birth weight was 2206±200.9 gm for cases and 2934±305.79 gm for the control group. Maternal MUAC was ≤23 cm in 52% of cases and only 16% in controls (OR- 5.69, CI: 2.23-13.74, p-value=0.001). A linear correlation was found between maternal MUAC and birth weight (r-value=0.3376, p-value=0.001). Conclusion: As there was a positive correlation between maternal MUAC ≤23 cm and LBW babies, maternal MUAC can be used as a predictor of LBW, and hence, measurement of maternal MUAC should be included during antenatal check-ups

Experimental and theoretical studies in isotachophoresis.

Isotachophoresis (ITP), a mode of electrophoresis, was studied experimentally and theoretically. Although this technique has not been used widely for protein separations, it has features conducive to large scale purification. These include high product concentrations and the use of common biochemical buffers. This technique was applied in this work to purify major proteins of human plasma. Experiments were performed on the Recycling Isotachophoresis (RITP) apparatus, which was developed earlier in our research group. The separations were optimized by varying the buffers, polarity of separation, buffer pH and the use of spacers. Computer simulations were used to optimize these separations. Two novel operating schemes were developed to use the advantages of ITP and scale up the apparatus by semi-continuous operation. The effect of imposed convective flows on the separation process was studied through experiments and computer modeling. Previously developed computer model was modified to simulate convective flows. This work led to identification and use of counterflow (CF) as an additional optimization parameter in ITP. Transport modeling has also been used to study the effect of recycling in the RITP apparatus. The effect of CF velocity profile on ITP steady state zonal structure was analyzed. Imposed CF with parabolic flow profile increases the effective dispersivity in the direction of electromigration, thus reducing the resolution. Uniform plug-flow type counterflows however do not affect the resolution. The improved simulation model incorporating convective flows is also applicable in simulating the effect of electroosmotic flows in analytical capillary electrophoresis.Digitization note: p. 230 missing from paper original; appears to be a pagination error rather than missing content

India's Low Carbon Electricity Futures

Decarbonizing its electricity sector through ambitious targets for wind and solar is India’s major strategy for mitigating its rapidly growing carbon emissions. In this dissertation, I explore the economic, social, and environmental impacts of wind and solar generation on India’s future low-carbon electricity system, and strategies to mitigate those impacts. In the first part, I apply the Multi-criteria Analysis for Planning Renewable Energy (MapRE) approach to identify and comprehensively value high-quality wind, solar photovoltaic, and concentrated solar power resources across India in order to support multi-criteria prioritization of development areas through planning processes. In the second part, I use high spatial and temporal resolution models to simulate operations of different electricity system futures for India. In analyzing India’s 2022 system, I find that the targets of 100 GW solar and 60 GW wind set by the Government of India that are likely to generate 22% of total annual electricity, can be integrated with very small curtailment (approximately 1%). Further, I find that flexibility strategies that include increasing the size of the balancing area (moving from state level to regionally coordinated scheduling and dispatch), lowering the minimum generation levels of thermal plants, and increasing inter-regional transmission capacity are the most effective in decreasing production costs and renewable energy curtailment. In the final part of this dissertation, I examined the effects of different mixes and targets of wind and solar installed capacities on overall system cost and avoided emissions in 2030. I find that the value of renewable energy decreases with increasing penetration across all mixes of wind and solar, with value of solar decreasing faster with higher penetration than wind. In India, the limited correlation of wind and solar generation profiles with load leads to a relatively small conventional generation capacity being avoided by renewable energy. The data sets, models, and tools developed through these analyses can be used to evaluate future low carbon electricity systems, and develop strategies and policies to ensure that integration of wind and solar is cost-effective and socially and environmentally sustainable
