Performance Evaluation of Multiple Helical Tubes as a Receiver for Solar Parabolic Trough Collector
No full textSolar parabolic trough collector consists of a parabolic reflector with a central receiver at a focal point through which heat transfer fluid is passed. Parabolic trough collector is used mostly in solar thermal power plants for generating electricity. This paper describes the experimental results of two straight tubes wrapped over each other to form a helically shaped receiver. The receiver was tested with aluminium material with and without black paint over it. Also, the helical tube receiver was tested with a glass cover over it, at two different mass flow rates and, with and without manual tracking. The tested instantaneous thermal efficiency ranges from 31.26% to 45.28% and the overall thermal efficiency ranges from 14.9% to 31.41% during the experimental period. The instantaneous thermal efficiency increased by an average of 1.32 times for unpainted receiver and 1.36 times for black painted receiver with the increase in mass flow rate. By tracking the parabolic collector according to sun’s position, there is an average increase in instantaneous thermal efficiency by 1.1 times for unpainted receiver and 1.04 times for black painted receiver. The paper further reveals that the use of multiple helical tubes as a receiver for parabolic trough collector increases the overall efficiency of the collector in a substantial manner

Core genome-based typing of Listeria monocytogenes
No full textThe precise delineation of lineages and clonal groups are a prerequisite to examine for within-species genetic variations particularly with respect to pathogenic potential. We used a whole-genome based approach to subtype isolates of the species Listeria monocytogenes. Core genome typing was performed employing three different approaches: total core genes (CG), high scoring pairing segments (HSPs) and average nucleotide identity (ANI). Examination of 113 in-house and publicly available L. monocytogenes genomes using these three methods revealed that isolates of these species could be assigned to 33 phylogenomic groups (PG). Each PG can be sub-differentiated into a number of genomic-types (GT) depending on the approach used: HSPs (n=57 GTs); CG (n=71 GTs) and ANI (n=83 GTs). Demarckation of PGs is concordant with the four known lineages, and led to the identification of sublineages in the lineage groups I, II and III. In addition, PG assignments had similar discriminatory power as MVLST types and clonal complexes (CCs) of MLST. Clustering of genomically highly similar isolates from different countries, sources, and isolation dates using PG suggested dispersion of phylogenomic clones of L. monocytogenes preceded their subsequent evolution. Classification according to phylogenomic groups may act as a guideline for future epidemiological studies.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

T.; Zola, S.; Jindal, I.; Kumar, R.; Chan, L.; Fuentes, M.; Lambiase, G.; Kalinowski, K. K.; Jamal, W.We present the largest optical photometry compilation of gamma-ray bursts (GRBs) with redshifts (z). We include 64813 observations of 535 events (including upper limits) from 28 February 1997 to 18 August 2023. We also present a user-friendly web tool grbLC which allows users to visualize photometry, coordinates, redshift, host galaxy extinction, and spectral indices for each event in our database. Furthermore, we have added a Gamma-ray Coordinate Network (GCN) scraper that can be used to collect data by gathering magnitudes from the GCNs. The web tool also includes a package for uniformly investigating colour evolution. We compute the optical spectral indices for 138 GRBs, for which we have at least four filters at the same epoch in our sample, and craft a procedure to distinguish between GRBs with and without colour evolution. By providing a uniform format and repository for the optical catalogue, this web-based archive is the first step towards unifying several community efforts to gather the photometric information for all GRBs with known redshifts. This catalogue will enable population studies by providing light curves (LCs) with better coverage since we have gathered data from different ground-based locations. Consequently, these LCs can be used to train future LC reconstructions for an extended inference of the redshift. The data gathering also allows us to fill some of the orbital gaps from Swift in crucial points of the LCs, e.g. at the end of the plateau emission or where a jet break is identified. © 2024 The Author(s).We acknowledge Elena Zaninoni for kindly providing part of the

Exploring the cost-effectiveness of high versus low perioperative fraction of inspired oxygen in the prevention of surgical site infections among abdominal surgery patients in three low- and middle-income countries
No full textBackground: This study assessed the potential cost-effectiveness of high (80–100%) vs low (21–35%) fraction of inspired oxygen (FiO2) at preventing surgical site infections (SSIs) after abdominal surgery in Nigeria, India, and South Africa. Methods: Decision-analytic models were constructed using best available evidence sourced from unbundled data of an ongoing pilot trial assessing the effectiveness of high FiO2, published literature, and a cost survey in Nigeria, India, and South Africa. Effectiveness was measured as percentage of SSIs at 30 days after surgery, a healthcare perspective was adopted, and costs were reported in US dollars (216 compared with 6 (95% confidence interval [CI]: −1) difference in costs. In India, the average cost for high FiO2 was 195 for low FiO2 leading to a −15 to −1164 compared with 93 (95% CI: −65) difference in costs. The high FiO2 arm had few SSIs, 7.33% compared with 8.38% for low FiO2, leading to a −1.05 (95% CI: −1.14 to −0.90) percentage point reduction in SSIs. Conclusion: High FiO2 could be cost-effective at preventing SSIs in the three countries but further data from large clinical trials are required to confirm this. © 2023 The Author
