(Oxford University Press, 2019)We present the first release of the data and compact-source catalogue for the JCMT Large Program SCUBA-2 Continuum Observations of Pre-protostellar Evolution (SCOPE). SCOPE consists of 850 μm continuum observations of 1235 ...
-
(NLM (Medline), 2019)Postmenopausal hyperandrogenism constitutes a very rare condition of tumoral or non-tumoral origin primarily residing either in the ovary or in the adrenal glands. We present herein two cases with this condition; one with ...
-
(American Chemical Society, 2019)To date, a large number of active molecules are hydrophilic and aromatic low molecular-weight drugs (HALMD). Unfortunately, the low capacity of these molecules to interact with excipients and the fast release when a ...
-
(Elsevier B.V., 2019)Piscirickettsiosis caused by the intracellular bacterium Piscirickettsia salmonis and caligidosis produced by the ectoparasite Caligus rogercresseyi, are important diseases which generate great economic losses in salmonid ...
-
(Emerald Group Publishing Ltd., 2019)Purpose: The paper aims to investigate the possibilities to control friction in lubricated systems by surface patterning, making use of a multi-scale approach. Surface patterns inside the tribological contact zone tend to ...
-
(Public Library of Science, 2019)Iron is essential for the normal development of cellular processes. This metal has a high redox potential that can damage cells and its overload or deficiency is related to several diseases, therefore it is crucial for its ...
-
(Elsevier Ltd, 2019)Silver (Ag) is a non-essential metal known to bioaccumulate in aquatic organisms. We determined Ag concentrations in five false killer whales stranded in South America. Silver concentrations (in dry weight basis) range as ...
-
(MDPI AG, 2019)In mineral processing, the common requirement for progressively finer milling due to the decreasing of ore grades implies the need for more challenging water recovery conditions in thickeners. Several mining operations ...
-
(Elsevier Inc., 2019)Photosensitized reactions mediated by endogenous chromophores have been associated with the etiology of age-related cataract disease. Endogenous chromophores such as 3-hydroxykynurenine (3OHKN) can be found in both free ...
-
(MDPI AG, 2019)A ten-year food preference database (2007–2017) was used to relate food selection in dogs to the nutritional components of diets by doing a principal component analysis (PCA) and a linear regression between components ...
-
TiO2/SiO2 Composite for Efficient Protection of UVA and UVB Rays Through of a Solvent-Less Synthesis (Springer New York LLC, 2019)In an effort to discover new inorganic UV absorbers, titania included into silica was prepared using a solvent-less solid state method involving the pyrolysis of the as prepared precursor Chitosan·(TiOSO4)/SiO2, as an ...
-
(Elsevier B.V., 2019)The present study evaluates the vibrational energy propagation from an O[dbnd]C stretching through the double or single bonds of two small carboxamide molecules. The results show that double bonding facilitates vibrational ...
-
(Wiley-VCH Verlag, 2019)In the present work, finite element simulations to investigate nanosecond pulsed laser ablation of stainless steel under low laser fluence conditions is performed. The laser has a wavelength of 1064 nm as well as a Gaussian ...
-
(Academic Press, 2019)The manufacture of traditional cheese varieties by mixing different proportions of cow and goat milk has become a common practice to obtain products with different appearance, texture and flavor. This study aimed to evaluate ...
-
(Frontiers Media S.A., 2019)Enteroaggregative Escherichia coli (EAEC) infections are one of the most frequent causes of persistent diarrhea in children, immunocompromised patients and travelers worldwide. The most prominent colonization factors of ...
-
(Cambridge University Press, 2019)This paper presents new excavation data on the Chinchihuapi I (CH-I) locality within the Monte Verde site complex, located along Chinchihuapi Creek in the cool, temperate Valdivian rain forest of south-central Chile. The ...
-
(Public Library of Science, 2019)Pine invasion is a global threat that is occurring in native forests of diverse regions of the world. This process is arising in a scenario of rapid forest deforestation and degradation. Therefore, elucidate which forests ...
-
(Springer Netherlands, 2019)Thinning is an agronomic practice that consists in the removal of a certain number of fruits, thereby altering the source–sink equilibrium in the tree and favoring carbon allocation to the remaining fruits. If thinning is ...
-
(Elsevier Espana S.L., 2019)Alcohol-related liver disease (ALD) is a major cause of advanced chronic liver disease in Latin-America, although data on prevalence is limited. Public health policies aimed at reducing the alarming prevalence of alcohol ...
-
(Nature Publishing Group, 2019)Species delimitation in minute freshwater snails is often difficult to perform using solely shell morphology. The problem intensifies when invasive species spread within the distribution range of morphologically similar ...
