Abstract

The purpose of this study was to investigate the feasibility of transesterifying waste oils using alcohol and a catalyst to provide a sustainable fuel alternative. To ensure that the resulting biodiesel met American Society for Testing and Materials (ASTM) criteria, we studied its most important parameters of diesel‐ethanol-waste oil cooking and plastics blends. We were able to separate out three unique fuel mixtures: BF0 (100% diesel), E20 (20% ethanol and 80% diesel), W20 (20% waste cooking oil and 80% diesel), and P20 (20% waste plastics oil and 80% diesel). In this experiment, a single-cylinder, computer-controlled diesel engine with direct injection was used. Fuel consumption increased by 4.3% for W20, 6.7% for E20, and 0.4% for P20, while thermal efficiency decreased by 2.1% for W20, 4.2% for P20, and 2.1% for E20, based on measurements conducted at 23.5 °b top dead center (TDC), compression ratio (CR19) under full load. At 23.5 °b TDC injection time, NOx emissions were observed to be lower. Adding 20% W to conventional fuel at 23.5 °b TDC enhanced the engines combustion characteristics. [ABSTRACT FROM AUTHOR]

Abstract

The development of nutrient-use efficient rice lines is a priority amidst the changing climate and depleting resources viz., water, land, and labor for achieving sustainability in rice cultivation. Along with the traditional transplanted irrigated system of cultivation, the dry direct-seeded aerobic system is gaining ground nationwide. The root-related traits play a crucial role in nutrient acquisition, adaptation and need to be concentrated along with the yield-attributing traits. We phenotyped an association panel of 118 rice lines for seedling vigour index (SVI) traits at 14 and 21 days after sowing (DAS), root-related traits at panicle initiation (PI) stage in polythene bags under controlled aerobic condition, yield and yield-related traits under the irrigated condition at ICARIIRR, Hyderabad, Telangana; irrigated and aerobic conditions at ARS, Dhadesugur, Raichur, Karnataka. The panel was genotyped using simple sequence repeats (SSR) markers and genome-wide association studies were conducted for identifying marker-trait associations (MTAs). Significant correlations were recorded for root length, root dry weight with SVI, root volume at the PI stage, number of productive tillers per plant, spikelet fertility, the total number of grains per panicle with grain yield per plant under irrigated conditions, and the total number of grains per panicle with grain yield per plant under aerobic condition. The panel was divided into three sub-groups (K = 3) and correlated with the principal component analysis. The maximum number of MTAs were found on chromosomes 2, 3, and 12 with considerable phenotypic variability. Consistent MTAs were recorded for SVI traits at 14 and 21 DAS (RM25310, RM80, RM22961, RM1385), yield traits under irrigated conditions (RM2584, RM5179, RM410, RM20698, RM14753) across years at ICAR-IIRR, grain yield per plant (RM22961, RM1146) under the aerobic condition, grain yield per plant at irrigated ICAR-IIRR and SVI (RM5501), root traits at PI stage (RM2584, RM80, RM410, RM1146, RM18472). Functionally relevant genes near the MTAs through in-silico expression analysis in root and panicle tissues viz., HBF2 bZIP transcription factor, WD40 repeat-like domain, OsPILS6a auxin efflux carrier, WRKY108, OsSCP42, OsMADS80, nodulin-like domain-containing protein, amino acid transporter using various rice expression databases were identified. The identified MTAs and rice lines having high SVI traits (Langphou, TI-128, Mouli, TI-124, JBB-631-1), high yield under aerobic (Phouren, NPK-43, JBB-684, Ratnamudi, TI-112), irrigated conditions (KR-209, KR-262, Phouren, Keibi-Phou, TI-17), robust root traits like root length (MoirangPhou-Angouba, Wangoo-Phou, JBB-661, Dissi, NPK-45), root volume (Ratnachudi, KJ-221, Mow, Heimang-Phou, PUP-229) can be further employed in breeding programs for the targeted environments aimed at improving seedling vigour, yield-related traits under irrigated condition, aerobic condition as adaptability to water-saving technology.

Abstract

In the last six decades, the consumption of reactive nitrogen (Nr) in the form of fertilizer in India has been growing rapidly, whilst the nitrogen use efficiency (NUE) of cropping systems has been decreasing. These trends have led to increasing environmental losses of Nr, threatening the quality of air, soils, and fresh waters, and thereby endangering climate-stability, ecosystems, and human-health. Since it has been suggested that the fertilizer consumption of India may double by 2050, there is an urgent need for scientific research to support better nitrogen management in Indian agriculture. In order to share knowledge and to develop a joint vision, experts from the UK and India came together for a conference and workshop on “Challenges and Opportunities for Agricultural Nitrogen Science in India.” The meeting concluded with three core messages: (1) Soil stewardship is essential and legumes need to be planted in rotation with cereals to increase nitrogen fixation in areas of limited Nr availability. Synthetic symbioses and plastidic nitrogen fixation are possibly disruptive technologies, but their potential and implications must be considered. (2) Genetic diversity of crops and new technologies need to be shared and exploited to reduce N losses and support productive, sustainable agriculture livelihoods. (3) The use of leaf color sensing shows great potential to reduce nitrogen fertilizer use (by 10–15%). This, together with the usage of urease inhibitors in neem-coated urea, and better management of manure, urine, and crop residues, could result in a 20–25% improvement in NUE of India by 2030.

Abstract

Background In a cohort of persons with diabetes (PWDs) seeking care at a tertiary care center, we aimed to determine the proportion of PWDs eligible and willing for down referral to primary health centers (PHCs). Methods We conducted a cross-sectional analytical study among PWDs on treatment for at least 1 year. PWDs with stable blood sugar, no history of cardiovascular events and proliferative retinopathy were considered as 'eligible' for primary care management. Results Of the total 1002 PWDs, mean (SD) age was 56 (12) years; 62% were male and 81% were from rural areas. About half (49%) of them were on insulin, and 52% had comorbidities. In total, 45.6% (95% CI: 42.3–48.8%) were eligible to be managed at PHCs. Among those who were eligible, 46.6% were willing to go back to PHCs. Males (APR = 1.16), people with diabetes for more than 10 years (APR = 1.23), and the presence of comorbidities (APR = 1.13) were significantly associated with unwillingness. Quality of medicines (46%) and poor facilities (40%) at PHCs were the main reasons for unwillingness. Conclusions About half of the PWDs availing care at tertiary hospitals can be managed at primary care settings; of those, only half were willing to receive care at PHCs. [ABSTRACT FROM AUTHOR]
