(ELSEVIER SCIENCE INC, 2008-09-01)The objectives were to characterize the estrus detection risk (HDR), conception risk (CR), and pregnancy rate (PR) of postpartum (pp) Holstein cattle from the central area of Chile. The study used records of 2269 lactations ...
-
(Springer, 2015)Let S be a set of 2n points on a circle such that for each point p∈S also its antipodal (mirrored with respect to the circle center) point p′ belongs to S. A polygon P of size n is called antipodal if it consists of precisely ...
-
(Wiley-Blackwell, 2016)Bone marrow adipose tissue (BMAT) is associated with low bone mass, although the functional consequences for skeletal maintenance of increased BMAT are currently unclear. BMAT might have a role in systemic energy metabolism, ...
-
(Springer, 2020)The ordinary differential equation x˙ (t) = f(x(t)), t ≥ 0, for f measurable, is not sufficiently regular to guarantee existence of solutions. To remedy this we may relax the problem by replacing the function f with its ...

(American Association of Avian Pathologists, 1999)Three fowl adenovirus (FAV) isolates (341, 344, and 215) obtained during 1996-97 from field outbreaks of inclusion body hepatitis/hydropericardium syndrome (IBH/HPS) affecting broilers and broiler breeders in Chile were ...
-
(Wiley-VCH Verlag, 2019)In the present study, 20 psychrotolerant yeast species isolated from the soils of King George Island in the sub-Antarctic region were evaluated for the production of extracellular gelatinase, an enzyme with high potential ...
-
(INIA, 2013)The genetic coefficients, representative of a crop, are necessary to use growth models; in many cases the range of the species is known, but there are no specific values for varieties. Durum wheat (Triticum turgidum L. ...
-
(2011)One of the capabilities developed by bacteria is the ability to gain large fragments of DNA from other bacteria or to lose portions of their own genomes. Among these exchangeable fragments are the genomic islands (GIs). ...
-
(Universidad Nacional de Colombia. Facultad de Ingeniería, 2021)This study aims to characterize a series of highrise reinforced concrete wall buildings located in Antofagasta, Chile, by means of a set of structural indexes commonly used in professional activities in our country and ...
-
(MDPI, 2022)High-risk human papillomaviruses (HR-HPVs) are the etiological agents of cervical cancer. However, a low proportion of HR-HPV-infected women finally develop this cancer, which suggests the involvement of additional cofactors. ...
-
(BLACKWELL, 2006-01)In this study, a competitive PCR was developed to estimate the quantity of bifidobacteria in human faecal samples using two 16S rRNA gene Bifidobacterium genus-specific primers, Bif164f and Bif662r. A PCR-temporal temperature ...
-
(2004)Polycrystalline calcium titanate films up to 300 nm in thickness were grown on titanium and Ti6Al4V substrates by the hydrothermal–electrochemical technique in an autoclave at 200 ◦C. The films examined by x-ray ...
-
(Elsevier, 2020)The hydroxymethylpyrimidine phosphate kinases (HMPPK) encoded by the thiD gene are involved in the thiamine biosynthesis pathway, can perform two consecutive phosphorylations of 4-amino-5-hydroxymethyl-2methyl pyrimidine ...
-
(Elsevier Science Publishers B.V., 1999)A set of aerosol samples collected during major volcanic activities around the Chilean site Lonquimay in the years 1988-1990 has been subjected to measurements in conventional and microPIXE modes in the Debrecen institute. ...
-
(Nature Publishing Group, 2016)Purpose: CDKN2A is the main high-risk melanoma-susceptibility gene, but it has been poorly assessed in Latin America. We sought to analyze CDKN2A and MC1R in patients from Latin America with familial and sporadic multiple ...
-
(2013)Context. Despite increasing research in massive star formation, little is known about its earliest stages. Infrared dark clouds (IRDCs) are cold, dense and massive enough to harbour the sites of future high-mass star ...
-
(1967)Four isoenzymes of adenosine triphosphate (ATP):d-hexose 6-phosphotransferase have been separated from rat liver by DEAE-cellulose. Three of these isoenzymes (A-C) are similar to animal hexokinases inasmuch as they exhibit ...
-
(Springer, 2013)We give a necessary and sufficient condition for a difference of convex (DC, for short) functions, defined on a normed space, to be Lipschitz continuous. Our criterion relies on the intersection of the ε-subdifferentials ...
