Published: January 2021

El presente artículo científico trata el estudio y simulación de un radiador que se basa en un intercambiador de calor tubular de flujo cruzado, el cual tiene un propósito de refrigerar el procesador, tarjeta gráfica de una CPU o diversos hardware en los sistemas de computación. Se realizan diversas simulaciones en el programa ANSYS teniendo varias temperaturas de ingreso que van en rangos desde 75 °C hasta 90 °C y con flujos másicos diferentes. Los resultados muestran que, al aumentar la temperatura de ingreso del fluido a refrigerar, la salida de este fluido tambien aumenta. Sin embargo, cuando se aumenta el flujo másico existe una merma en el rechazo de calor en los dispositivos computacionales.

Abstract
The Nancy Grace Roman Space Telescope (Roman) will provide an enormous number of microlensing light curves with much better photometric precision than ongoing ground-based observations. Such light curves will enable us to observe high-order microlensing effects which have been previously difficult to detect. In this paper, we investigate Roman's potential to detect and characterize short-period planets and brown dwarfs (BDs) in source systems using the orbital motion of source stars, the so-called xallarap effect. We analytically estimate the measurement uncertainties of xallarap parameters using Fisher matrix analysis. We show that the Roman Galactic Exoplanet Survey can detect warm Jupiters with masses down to 0.5 M
Jup and orbital periods of 30 days via the xallarap effect. Assuming a planetary frequency function from Cumming et al., we find Roman will detect ∼10 hot and warm Jupiters and ∼30 close-in BDs around microlensed source stars during the microlensing survey. These detections are likely to be accompanied by the measurements of the companion’s masses and orbital elements, which will aid in the study of the physical properties for close-in planet and BD populations in the Galactic bulge.

Abstract
We analyze the wavelength dependence of the far-infrared polarization fraction toward the OMC-1 star-forming region using observations from HAWC+/SOFIA at 53, 89, 154, and 214 μm. We find that the shape of the far-infrared polarization spectrum is variable across the cloud and that there is evidence of a correlation between the slope of the polarization spectrum and the average line-of-sight temperature. The slope of the polarization spectrum tends to be negative (falling toward longer wavelengths) in cooler regions and positive or flat in warmer regions. This is very similar to what was discovered in ρ Oph A via SOFIA polarimetry at 89 and 154 μm. Like the authors of this earlier work, we argue that the most natural explanation for our falling spectra is line-of-sight superposition of differing grain populations, with polarized emission from the warmer regions and less-polarized emission from the cooler ones. In contrast with the earlier work on ρ Oph A, we do not find a clear correlation of polarization spectrum slope with column density. This suggests that falling spectra are attributable to variations in grain alignment efficiency in a heterogeneous cloud consistent with radiative torques theory. Alternative explanations in which variations in grain alignment efficiency are caused by varying gas density rather than by varying radiation intensity are disfavored.

Abstract
We developed a data-driven model to map stellar parameters (T
eff,

, and

) accurately and precisely to broadband stellar photometry. This model must, and does, simultaneously constrain the passband-specific dust reddening vector in the Milky Way,
R
. The model uses a neural network to learn the (de-reddened) absolute magnitude in one band and colors across many bands, given stellar parameters from spectroscopic surveys and parallax constraints from Gaia. To demonstrate the effectiveness of this approach, we train our model on a data set with spectroscopic parameters from LAMOST, APOGEE, and GALAH, Gaia parallaxes, and optical and near-infrared photometry from Gaia, Pan-STARRS 1, Two Micron All Sky Survey and Wide-field Infrared Survey Explorer. Testing the model on these data sets leads to an excellent fit and a precise—and by construction—accurate prediction of the color–magnitude diagrams in many bands. This flexible approach rigorously links spectroscopic and photometric surveys, and also results in an improved, T
eff-dependent
R
. As such, it provides a simple and accurate method for predicting photometry in stellar evolutionary models. Our model will form a basis to infer stellar properties, distances, and dust extinction from photometric data, which should be of great use in 3D mapping of the Milky Way.

The Observed Rate of Binary Black Hole Mergers can be Entirely Explained by Globular Clusters

Published: January 2021

Abstract
Since the first signal in 2015, the gravitational-wave detections of merging binary black holes (BBHs) by the LIGO and Virgo collaborations (LVC) have completely transformed our understanding of the lives and deaths of compact object binaries, and have motivated an enormous amount of theoretical work on the astrophysical origin of these objects. We show that the phenomenological fit to the redshift-dependent merger rate of BBHs from Abbott et al. is consistent with a purely dynamical origin for these objects, and that the current merger rate of BBHs from the LVC could be explained entirely with globular clusters alone. While this does not prove that globular clusters are the dominant formation channel, we emphasize that many formation scenarios could contribute a significant fraction of the current LVC rate, and that any analysis that assumes a single (or dominant) mechanism for producing BBH mergers is implicitly using a specious astrophysical prior.

Sous la monarchie de Juillet, l’agence matrimoniale De Foy connaît une importante prospérité. L’étude de trois de ses registres, retrouvés aux Archives de Paris met en lumière de nouvelles pratiques d’intermédiation marchandes. Au bureau de l’agent matrimonial, de jeunes hommes pressés de s’intégrer par le mariage à la société parisienne monnayent un accès aux jeunes filles de bonnes familles, ignorantes de toute l’affaire, en passant par un complexe réseau d’informateurs et intermédiaires. Tout en présentant le fonctionnement de ce commerce d’appariement opaque, l’article interroge à nouveaux frais l’histoire du choix du conjoint au début du xix e siècle. Dans une capitale en proie aux transformations urbaines et sociales, où la bourgeoisie consolide les frontières de la sphère privée, l’agence matrimoniale endosse en rôle social crucial : assurer la mobilité sociale par le mariage de celles et ceux qui s’adressent à elle.

AbstractCaptive-rearing conservation programs focus primarily on maximizing postrelease survival. Survival increases with size in a variety of taxa, often leading to the use of enhanced size as a means to minimize postrelease losses. Head-starting is a specific captive-rearing approach used to accelerate growth in captivity prior to release in the wild. We explored the effect of size at release, among other potential factors, on postrelease survival in head-started Mojave desert tortoises Gopherus agassizii. Juvenile tortoises were reared for different durations of captivity (2–7 y) and under varying husbandry protocols, resulting in a wide range of juvenile sizes (68–145 mm midline carapace length) at release. We released all animals (n = 78) in the Mojave National Preserve, California, United States, on 25 September 2018. Release size and surface activity were the only significant predictors of fate during the first year postrelease. Larger sized head-starts had higher predicted survival rates when compared with smaller individuals. This trend was also observed in animals of the same age but reared under different protocols, suggesting that accelerating the growth of head-started tortoises may increase efficiency of head-starting programs without decreasing postrelease success. Excluding five missing animals, released head-starts had 82.2% survival in their first year postrelease (September 2018–September 2019), with all mortalities resulting from predation. No animals with &gt;90-mm midline carapace length were predated by ravens. Our findings suggest the utility of head-starting may be substantially improved by incorporating indoor rearing to accelerate growth. Target release size for head-started chelonians will vary among head-start programs based on release site conditions and project-specific constraints.

Published: January 2021

AbstractIn the past two decades, Salt Plains National Wildlife Refuge has been increasingly recognized as important habitat for both breeding and migratory shorebirds. North American snowy plovers Charadrius nivosus in particular rely on the nearly 5,000-ha salt flat at Salt Plains National Wildlife Refuge, which thousands use as breeding and stopover habitat. Elsewhere on the Southern Great Plains, decadal declines up to 75% within snowy plover subpopulations have been documented and attributed to vegetation encroachment, increased rates of nest predation, and decreased availability of fresh surface water. Despite many attempts to estimate this species' abundance across the continent, to date, no known attempt at distance sampling of snowy plovers has occurred. To address this paucity of data, we assessed feasibility of distance sampling methods to accurately estimate snowy plover abundance and detectability. Distance sampling surveys (2017–2018) indicated high detection probability (P = 0.80) and the population abundance estimate across the salt flat extrapolated to 3,307 individuals. The distance-sampling population abundance estimate is lower than population abundance estimates determined by two previous studies within the past decade but far greater than 2,105 estimated for a study in 2006. Overall, distance sampling snowy plovers at Salt Plains National Wildlife Refuge proved to be an effective addition to pre-established survey protocols but further investigation is needed to compare accuracy and precision of methods used in this study, annual surveys conducted by Salt Plains National Wildlife Refuge, and other potential snowy plover surveys.

Published: January 2021

Cet article propose une étude empirique des déterminants socioéconomiques et géographiques de l’adoption d’Internet et de l’achat en ligne au Maroc. Nous avons administré un questionnaire auprès de 2 254 individus localisés dans trois villes marocaines diamétralement opposées du point de vue des conditions socioéconomiques. Nous justifions ce choix méthodologique par la volonté de déceler de potentielles divergences de comportement envers ce nouveau mode d’achat selon les conditions économiques locales et selon le profil socioéconomique des individus. Nous avons estimé huit modèles économétriques avec comme variables endogènes la décision individuelle d’adopter Internet et d’acheter sur Internet. Nos résultats corroborent ceux obtenus dans d’autres contextes. La localisation ne semble pas influencer la décision de se connecter à Internet. En revanche, la probabilité d’acheter en ligne augmente pour les personnes habitant dans la petite et la grande ville relativement à la ville de dimension moyenne.Classification JEL : L81, L86, D18, D12, C25.

Objectives: The aim of this study was to investigate the efficacy and safety of anti-interleukin-1 (anti-IL-1) agents and tumor necrosis factor‐alpha (TNF-α) inhibitors in renal transplant patients.
Patients and methods: Between February 2014 and February 2020, data of 12 renal transplant recipients (9 males, 3 females; median age: 51 years; range, 19 to 70 years) who received anti-IL-1 agents or TNF-α inhibitors for inflammatory diseases in the post-transplant time period and were followed in a single transplant center (n=12) were retrospectively analyzed. A total of 46 cases were reported in the literature, before the data were collected. The overall outcomes of all cases were analyzed in this study.
Results: Thirty-seven patients received anti-IL-1 agents in the post-transplant period. The main indications for anti-IL-1 agents were familial Mediterranean fever (FMF) and amyloidosis (75.7%). The continuation rate of colchicine treatment in patients with FMF was 85.7%. Anti-IL-1 agents prevented attacks completely in 89.3% of FMF patients. The number of cases used TNF-α inhibitors among renal transplant patients was lower (n=21). The TNF-α inhibitors were used mainly for inflammatory bowel diseases (57.1%) and ankylosing spondylitis (33.3%) and suppressed the disease activity in most of the patients with inflammatory diseases (72.7%). Death (n=3) and malignancies (n=3) were reported in patients who received TNF-α inhibitors, but not in patients who received anti-IL-1. The renal outcomes and graft survival rates were satisfactory in patients who received both anti-IL-1 agents and TNF-α inhibitors.
Conclusion: Our results support that anti-IL-1 agents can be used effectively and safely in renal transplant patients.

Doctors and paramedics as health resources are the main component of health care providers to the public to achieve health development goals by national goals. Doctors and paramedics are the vanguard of treating Covid-19 patients with a very high risk of transmission of the virus. Legal protections for Doctors and paramedics are often overlooked as if society is apathetic and opinionated that it is already a duty and responsibility as medical personnel. Legal protections for the safety of Doctors and paramedics are less noticed, even though medical personnel are the vanguard in the handling of the Covid-19 pandemic. Speaking of legal protections certainly cannot be released from rights and obligations. Unprotected health workers, in this case, the profession of health workers. Violation of the rights of Doctors and paramedics related to covid-19 patient services that often occur is that the patient does not provide honest information on his condition as a Person in supervision or Patient In Supervision, so the more prone to the transmission of the Covid-19 virus that certainly has a domino effect on both doctors, Doctors and paramedics, other patients and also their families. Legal protection of Doctors and paramedics should be a serious concern of governments and hospitals. The patient must need and trained to be honest with what he feels and does. Legal protections that will surely make Doctors and paramedics feel protected in carrying out their humanitarian duties. All good measures of the assessment until evaluation will be carried out properly. Synergy together is the way to be done for all to realize quality health care.
EFFECT OF ADAPTATION PRACTICES TO CLIMATE CHANGE ON AGRICULTURAL PRODUCTION BY FARMING HOUSEHOLD. A CRITICAL LITERATURE REVIEW
Authors: Kimani James 
Published: January 2021

Purpose: Climate change can disrupt food availability, reduce access to food, and affect food quality. Projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity. Increases in the frequency and severity extreme weather events can also interrupt food delivery, and resulting spikes in food prices after extreme events are expected to be more frequent in the future. Increasing temperatures can contribute to spoilage and contamination. The general objective of the study was to establish the effect of Adaptation practices to climate change and its impact on agricultural production by farming household.
Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps.
Findings: The study found out the locals households prefer multiple adaptation strategies to counter the effects of climate variability and change. The current local adaptation strategies include crop, diversification, shifting planting dates, off farm jobs and diversifying from farm to non – farm activities. However majority of the respondents employ crop diversification as the main adaptation strategy. For the locals’ crop diversification does, to an extent, guarantees good harvests although there are years in which farmers report total crop losses
Recommendations: The study recommends that policy efforts should be directed at enforcing adaptation measures of climate change in order to boost agricultural production
