Search for Gravitational Waves Associated with Gamma-Ray Bursts Detected by Fermi and Swift during the LIGO-Virgo Run O3b

We search for gravitational-wave signals associated with gamma-ray bursts (GRBs) detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced LIGO and Advanced Virgo (2019 November 1 15:00 UTC-2020 March 27 17:00 UTC). We conduct two independent searches: A generic gravitational-wave transients search to analyze 86 GRBs and an analysis to target binary mergers with at least one neutron star as short GRB progenitors for 17 events. We find no significant evidence for gravitational-wave signals associated with any of these GRBs. A weighted binomial test of the combined results finds no evidence for subthreshold gravitational-wave signals associated with this GRB ensemble either. We use several source types and signal morphologies during the searches, resulting in lower bounds on the estimated distance to each GRB. Finally, we constrain the population of low-luminosity short GRBs using results from the first to the third observing runs of Advanced LIGO and Advanced Virgo. The resulting population is in accordance with the local binary neutron star merger rate. © 2022. The Author(s). Published by the American Astronomical Society

Open data from the third observing run of LIGO, Virgo, KAGRA, and GEO

The global network of gravitational-wave observatories now includes five detectors, namely LIGO Hanford, LIGO Livingston, Virgo, KAGRA, and GEO 600. These detectors collected data during their third observing run, O3, composed of three phases: O3a starting in 2019 April and lasting six months, O3b starting in 2019 November and lasting five months, and O3GK starting in 2020 April and lasting two weeks. In this paper we describe these data and various other science products that can be freely accessed through the Gravitational Wave Open Science Center at https://gwosc.org. The main data set, consisting of the gravitational-wave strain time series that contains the astrophysical signals, is released together with supporting data useful for their analysis and documentation, tutorials, as well as analysis software packages

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

INFLUENCE OF FEEDING PROBIOTICS ON GROWTH PERFORMANCE AND NUTRIENT DIGESTIBILITY IN RABBITS

[EN] During a 84 days trial, growth performance and nutrient utilisation were studied on 33 New Zealand White (NZW) rabbits (initial age 42 ± 3 days and average body weight 633 ± 21g), divided into three groups of 11 animals each. All the rabbits were given a common pelleted ration. Animals of group 2 were provided a supplemental daily dose of lactic acid producing bacteria (Lacto) 5x1 oª cells/animal and ¡roup 3 received a mixed with equal quantity dose 5x1 O cells/animal/day of lactic acid bacteria and Saccharomyces cerevisiae (Lacto+ Sacc). There were no differences in feed intake, body weight gain (average 8.1g/day), feed conversion efficiency (average 4. 71 g feed intake/g gain) and digestibility of dry matter, neutral detergent fibre, acid detergent fibre, cellulose and hemicellulose among the groups. Only crude protein digestibility was significantly improved (P<0.05) in the animals given mixed culture (Lacto+ Sacc).[FR] Au cours d'un essai de 84 jours, la croissance et l'utilisation des aliments ont été étudiées sur 33 /apins Néo-zélandais Blancs (NZW) agés en moyenne de 42 ± 3 jours et d'un poids corpore/ moyen de 633 ± 21g, repartís en 3 groupes de 11.

EFFECT OF ORAL ADMINISTRATION OF YEAST ( Saccharomyces cerevisiae ) ON DIGESTIBILITY AND GROWTH PERFORMANCE OF RABBITS FED DIETS OF DIFFERENT FIBRE CONTENT

[EN] Thirty two laboratory strain New Zealand White rabbits aged about 6 weeks were divided into 4 equal groups. Rabbits were fed diets of 9. 73 % (/DM) fibre in group 1 and 2, and 12.86 % fibre in group 3 and 4. Yeast culture (Saccharomyces cerevisiae) ata rate of 5 x 1oa cells /animal /day was given orally to group 1 and 3. Dry matter intake was significantly (P<0.01) higher in the rabbits given high fibra diet but tlie digestibility coefficients of dry matter, organic matter, ether extract, nitrogen free extract and feed conversion efficiency were significantly better in the animals given low fibre diet. Adminisfration of yeast culture had no effect on weight gain or digestibility of nutrients.[FR] Trente deux lapins de laboratoire de race Néo Zélandais Blancs b.gés d'environ 6 semaines, ont été répartis en 4 groupes égaux. Ces lapins ont rer;u des régimes contenant 9,73 % pour les groupes 1et2, et 12,86 % de cellulose brute (!MS) pour les groupes 3 et 4. La culture de levure /Saccharomyces cerevisiae), au taux de 5 x 1()8 ce/fules /animal/jour, a été donnée oralement aux grou~s 1 et 3. La matiere seche ingérée était significativement (P<0.01} plus élevée chez les Tapins recevant le rég_ime le plus riche en fibre mais les coefficients de digestibilite de la matiere seche, de la matiere organique, de /'extrait éthéré, de l'extractif non azoté, et /'indice de consommation étaient significativement meilleur chez les animaux recevant le régime le plus pauvre en fibre. L'administration de levure reste sans effet sur le gain de poids et la digestibilité des élements nutritifs.Chaudhary, L.; Singh, R.; Kamra, D.; Pathak, N. (1995).

NUTRITIVE VALUE OF ROBINIA (Robinia pseudoacacia) LEAVES IN GROWING SOVIET CHINCHILLA RABBITS

[EN] Far determining the nutritiva value of robinia (Robinia pseudoacacia) leaves, widely distributed in the temperate and humid Himalayan ranges (29º25N and 79º35E), containing OM 89.9; CP 20.7; EE 3.8; CF 21.7; NFE 43.7; NDF 60.1; ADF 29.6; Ca 2.4 and P 0.2 par cent on DM basis, ten Soviet Chinchilla rabbits of six week old (mean body weight 792+73 g) were fed freshly lopped green robinia leaves as a sale feed far 56 d. The green leaves were offered individually at 400g/rabbit/day. A metabolism trial of 6 day was conducted after 21 d of experimental feeding. The digestibility of DM, OM, CP, EE, NDF and ADF was 74.3; 77.4; 36.8; 73.2; 60.3 and 29.4%, respectively. The average intake of DM was 145.3g/d and 143.79/1<9 WJ.75, DCP 11.29/d and 11.1g/kg wo.15 and DE 407.6 Kca1/d and 402.4Kca1/kg wo.75, which could not only meet the maintenance requirement but also supported 10.49 daily body weight gain. The dry matter of robinia leaves contained 8.0 percent DCP and 2.81 kcal DE/g. Results suggest that robinia leaves may be usad as a sale feed far maintenance. This may also be usad far the development of production rations by supplementation of energy and if necessary proteinacious feeds.[FR] Dix lapins Chinchilla Soviétigues agés de 6 semaines (poids vif mayen 792 ±73 g) ont été utihsés pour déterminer la valeur nutritiva des feuilles d'acacia largement utilisées dans la région tempérée et humide himalayenne située 29º25 N et 79•35 E. Au cours d'un essai de 56 jours les lapins ont été nourris exclusivement de feuilles d'acacia fraichement cueillies, contenant, en % de la matiare sache, 89,9% de matieres organiques, 20,7%de protéines brutas, 3,8% d'extrait éthéré, 21,7% de cellulose bruta, 43,7% d'extractif non azoté, 60,1% de NDF, 29,6% d'ADF, 2,4% Ca et 0,2% P. Chaque lapin recevait individuellement chaque jour 400g de feuilles vertes. Des mesures de digestibilité ont été effectuées pendant 6 jours apras le 21 eme jour de l'essai. La digestibilité de la matiare sache, de la matiere or9anique, des protéines brutas, de l'extrait éthéré, de NDF et ADF ont éte respectivement de : 74,3 ; 77,4 ; 36,8 ; 73,2 ; 60.3 et 29,4 %. La consommation de matiare sache moyenne a été de 145,3 g/jour et 143,7 g/kg pyo.75 ce qui permet de couvrir non seulement les besoins et mais aussi d'assurer un gain de poids vif journalier de 10,4 g. La matiare sache des feuilles d'acacia contient 8,0% de protéines digestibles et 2,81 kcal/g. Ces résultats suggarent que les feuilles d'acacia peuvent etre utilisées comme aliment unique pour assurer l'entretien et qu'elles peuvent aussi etre utilísées dans des rations de croissance en apP.ortant un supplément d'énergie et si nécessaire un complément proteique.Singh, P.; Chaudhary, L.; Verma, A.; Pathak, N.

Efeito de sementes oleaginosas inteiras e óleo de soja sobre a digestibilidade in vitro e os padrões ruminais de bezerros holandeses Effect of oleaginous whole seeds and soybean oil on the in vitro digestibility and ruminal pattern in holstein calves

Este trabalho foi realizado para comparar os efeitos da adição de sementes inteiras de soja e algodão e de óleo de soja sobre os padrões ruminais e a digestibilidade in vitro, em bezerros Holandeses fistulados. Dois bezerros fistulados no rúmen foram alimentados com dieta basal com 2,5% de extrato etéreo (EE), o qual foi comparado com dietas com 5,0% de EE, em que as sementes de soja e algodão inteira ou o óleo de soja foram fontes de EE adicional. A adição de sementes de soja e de algodão resultou em decréscimo na digestibilidade in vitro da matéria seca e da fibra em detergente neutro (FDN), porém não houve alterações na digestibilidade in vitro da fibra em detergente ácido (FDA) em relação à dieta controle. A adição de semente algodão provocou decréscimo na digestibilidade in vitro da proteína bruta em comparação à dieta controle. A concentração de ácido propiônico nas dietas com adição de óleo de soja foi 16% mais elevada que a proporcionada pelas demais dietas. O uso de óleo de soja pareceu ser a mais adequada em relação à digestibilidade da matéria seca, FDA e FDN e à manutenção de pH, quando comparado a outros tipos de adição lipídica, porém menos eficiente que a semente de soja em relação à digestibilidade in vitro da proteína bruta. O número de protozoários apresentou grande variação entre dietas, mas nenhum efeito com adição de óleo foi observado. A maior concentração de N-NH3 ruminal foi obtida na dieta com óleo de soja, quando comparada às outras dietas.<br>This work was conducted to compare the effects of whole soybean and cotton seeds and soybean oil on the ruminal pattern and in vitro disappearance, in fistulated Holstein calves. Two calves fitted with rumen cannula were fed a basal diet with 2.5% of ether extract (EE), which was compared with 5.0% EE, where whole soybean, whole cotton seeds or soybean oil were the source of additional EE. The addition of whole soybean and cottonseed resulted in decrease on in vitro dry matter and neutral detergent fiber disappearance, however there was no alteration in the in vitro acid detergent fiber disappearance in relation to the control diet. The addition of whole cottonseed decreased the crude protein in vitro disappearance compared to control diet. The propionic acid concentration in the diets with addition of soybean oil was 16% higher than that proportionated by the other diets. The use of soybean oil seems to be the most adequate in relation to dry matter, in vitro NDF, ADF disappearance and pH maintenance, when compared to the others types of lipid addition, however less efficiently than the soybean seed in relation to in vitro protein crude disappearance. The protozoa number presented great changes among diets, but no effect with oil addition was reported. The higher N-NH3 ruminal concentration was reported in the diet with soybean oil when compared with the other diets
