(UNIV CHICAGO PRESS, 2006-06-01)[ LPH96] 201.663 + 1.643, a diffuse H II region, has been reported to be a candidate for emission from rapidly spinning dust grains. We present Cosmic Background Imager (CBI) observations at 26 - 36 GHz that show no evidence ...
-
(Oxford University Press, 2017)The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment. We performed a series of observations of Proxima Centauri using Spectro-Polarimetric High-contrast ...
-
(Oxford University Press, 2019)Background Conventional nonresisted therapeutic exercises for people with hemophilia involve a careful, low-intensity approach to avoid injuries. Externally resisted exercise is highly efficient for increasing muscle ...

(Universidad de Chile, Facultad de Arquitectura y Urbanismo, 2018-06)Santiago de Chile, habitada por cerca de 7 millones de personas, se ubica a los pies del flanco occidental de la Cordillera Principal de Los Andes, uno de los cordones montañosos más activos de nuestro planeta. La zona ...
-
(Elsevier GmbH, 2019)Urbanization alters community composition, frequently leading to decline in native species abundance and richness. Nevertheless, responses might also depend on trait-based local habitat and landscape-scale filters. In this ...
-
(Oxford University Press, 2019)The aim of this study is to evaluate the impact of urgent care centres' (UCCs) implementation on emergency department (ED) and same-day visits in primary care in a Chilean public healthcare network. Quasi-experimental ...

USco1621 B and USco1556 B: two wide companions at the deuterium-burning mass limit in Upper Scorpius (EDP Sciences, 2020)Aims. Our objective is to identify analogues of gas giant planets, but located as companions at wide separations of very young stars. The main purpose is to characterise the binarity frequency and the properties of these ...
-
(ELSEVIER, 2006-04-28)The potential of selection in stages to increase genetic gain and profit in rainbow trout breeding was assessed. The theory of Cochran was utilized to predict genetic gains under alternative breeding schemes mimicking the ...
-
(ELSEVIER, 2006-06-15)Two lab-scale electrohydrolysis (EH) cells have been used to study the effectiveness of this method in the recovery of sulphuric acid from copper-containing electrolytes such as those present in copper electrorefining. ...
-
(MDPI AG, 2019)The objective of this study was to develop an encapsulated iron supplement for oral ingestion and to determine its effect on the iron nutrition status of suckling pigs. Encapsulated and non-encapsulated iron supplement was ...
-
(STARCH BLENDS, 2006-08-07)Functionalized metallocene copolymers synthesized from ethylene with 5-hexen-1-ol and ethylene with 10-undecen-1-ol were used as compatibilizers in LDPE/starch and LDPE/dextran blends in order to improve the interfacial ...
-
(BioMed Central Ltd., 2019)Background: There is little published regarding metabolism of Salinispora species. In continuation with efforts performed towards this goal, this study is focused on new insights into the metabolism of the three-identified ...

(WILEY-V C H VERLAG GMBH, 2006-08-02)Functionalized PP samples with different percentages of grafted IA, i.e., 0.7, 1 or 1.8 wt.-%, with similar molecular weights were used as compatibilizers in PP/clay nanocomposites. PP nanocomposites containing 1 wt.-% of ...
-
(Oxford University Press, 2013)The implicit function theorem is used to obtain some necessary and sufficient conditions, for which an implicit constitutive relation can be solved in terms of the stresses and strains, in the sense of expressing, for ...
-
(The Minerals, Metals & Materials Society, 2015)Dislocations are at the heart of the plastic behavior of materials yet they are very difficult to probe experimentally. Lack of a practical nonintrusive measuring tool for, say, dislocation density, seriously hampers ...
-
(Elsevier, 2018-06)Grinding media is very important in the mineral processing, mainly because its consumption involves significant costs of grinding and consequently, of the total mining operational expenditure. During grinding, chemical and ...
