Opis:
Background. Physalis peruviana L. fruit contains nutritional and bioactive compounds of immense importance to public health and represents a potential ingredient for the development of functional foods and beverages. Objective. This study aimed to determine the chemical and nutritional composition as well as the antioxidant capacity of the P. peruviana L. fruit grown in Peru in three areas of the Central Andean region. Material and methods. Proximal and physicochemical analyses and estimation of mineral content, vitamin C, total carotenoids, total polyphenols, and antioxidant capacity (2, 2-diphenyl-1-picrylhydrazyl [DPPH] and 2, 2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) [ABTS] assays) were performed using standardized methods. Results. The fruits were collected from three regions of the Peruvian Andes (Ancash, Cajamarca, and Cusco). The results showed that the content of potassium (306.54–327.60 mg/100 g) and iron (12.93–14.47 mg/kg) was prominent. The Physalis fruit had high levels of vitamin C (47.20–52.20 mg/100 g), total polyphenols (68.17–83.40 mg equivalents of gallic acid/100 g), and carotenoids (1.12–1.73 mg β-carotene/100 g). Higher values for antioxidant capacity were obtained with the ABTS method (896–1003.33 μmol Trolox/100 g) than with the DPPH method (290–309 μmol Trolox/100 g). Conclusions. This study confirms that the P. peruviana fruit has properties that could provide important health benefits and that it could be used for the development of functional foods and food supplement.

Opis:
The length of gestation in Carthusian broodmares was calculated on the basis of 339 spontaneous full-term deliveries taking place in the 8-year period 1998-2005 from 158 broodmares and 29 stallions in a major farm of Spanish horses of Carthusian strain in southern Spain. Ultrasonography was used to determine follicular dehiscence, 1st day of pregnancy and to confirm conception in mares. Mean GL was 332.4 ± 12.1 days, and a normal interval of 297-358 days was established for this breed. GL records were grouped on the basis of foal sex (colts or fillies), mating month (between November and January; February and April; May and July), age of the mare (4 to 7 years; 8 to 12 years; 13 to 17 years), breeding year, stallion and parity (primiparous vs. multiparous). GLs were 12.9 days shorter in mares mated between May and July than those mated between November and January and 15.3 days in mares mated between February and April (p<0.001). Mares aged between 8-12 years had 5.3 days shorter GLs than those aged between 13-17 years (p<0.05). Pregnancy was significantly 5.7 days longer when the mare gave birth to colts than fillies (p<0.05). GL was 14.5 days longer in primiparous than in multiparous mares (p<0.001). No statistical differences in GL were found between the studied years. This study shows the influence of certain stallion on GL.

Opis:
Prediction of machining-induced residual stresses is an interesting objective in the field of modelling manufacturing processes. Although Finite Element Analysis (FEA) has been widely used for this purpose, many problems are found when the numerical model is developed. Computational cost and numerical problems related to the extreme mesh distortion make the effort of finite element modelling of machining extremely time consuming. The aim of this work is to predict machinning-induced residual stresses using a finite element model based in ALE (Arbitrary Lagrangian Eulerian) approach. The finite element general-purpose code ABAQUS is used, modifying the previous model used in scientific literature to predict residual stresses. Boundary conditions in the entrance of the workpiece and in the upper border of the chip were modified from Lagrangian boundaries in the previous model, to Eulerian boundaries in the new model. Main advantages of the model presented in this work are low level of distortion of the mesh, the possibility of simulate long length of machined surface and time-efficiency. The model has been applied to calculate residual stresses in AISI 316L during machining. Reasonable agreement with experimental results has been found.
Przewidywanie szczątkowych naprężeń wywoływanych obróbką skrawaniemw materiale próbki stanowi interesujące zagadnienie modelowania tego typu technologii wytwarzania. Mimo, że analiza oparta na elementach skończonych znalazła szerokie zastosowanie w tej dziedzinie, jej skuteczność jest problematyczna na poziomie budowy modelu numerycznego. Koszt symulacji i kłopoty obliczeniowe związane z ogromnym zniekształceniem siatki elementów skończonych czynią ten rodzaj analizy wyjątkowo czasochłonnym. Celem tej pracy jest opis metody określania naprężeń szczątko- wych indukowanych obróbką skrawaniem za pomocą modelu z elementami skończonymi w opisie eulerowsko-lagrange'owskim ALE (ang. Arbitrary Lagrangian Eulerian). W obliczeniach zastosowano wielozadaniowy pakiet ABAQUS, który pozwolił na modyfikację dotychczas stosowanego modelu, opisanego w literaturze. Warunki brzegowe w obszarze wejścia noża w obrabiany materiał i górnej strefie wióra zmodyfikowano z typu Lagrange'a na Eulera w nowej wersji. Zaletą tego rozwiązania okazało się małe zniekształcenie siatki elementów skończonych, możliwość symulacji długich powierzchni obróbczych i znacznie krótszy czas obliczeń. Model wykorzystano do określenia naprężeń szczątkowych w stali AISI 316L podczas skrawania. Potwierdzono satysfakcjonującą zgodność symulacji z wynikami pomiarów doświadczalnych.

Introduction and objective. Burning coal and firewood generates toxic emissions that are associated with respiratory illness, cardiovascular disease, and even death. The aim of the study is to evaluate the association between county-level prevalence of household coal and firewood use and health outcomes, including total, respiratory, and cardiovascular mortality, as well as total and respiratory hospitalization rates. Materials and method. The ecological study included data on the use of household coal and firewood in 139 counties obtained from the 2015 Chilean National Socio-economic Characterization Survey. Total, respiratory, and cardiovascular mortality, as well as total and respiratory hospitalization rates, were obtained from the Department of Health Statistics. Poisson models with robust error variance, Pearson linear correlation coefficients, and scatterplots were used to explore associations between household coal and firewood use and morbidity-mortality, stratifying by geographic zone. Results. Total, respiratory, and cardiovascular mortality and total and respiratory hospitalization rates were 5.7 per 1,000, 552 per 100,000, 157 per 100,000, 92.5 per 1000, and 8.8 per 1000 inhabitants, respectively. The median prevalence of coal use for residential cooking, heating, or water heating was 3.64%, while the median prevalence of firewood combustion was 12%. In southern counties, age- and gender-adjusted respiratory mortality increased 2.02 (95% CI: 1.17–3.50), 1.5 (95% CI: 1.11–1.89), and 1.76-fold (95% CI: 1.19–2.60) for each percentage increase in household coal and firewood use for heating, cooking and heating water, respectively. Conclusions. The prevalence of household coal and firewood used for heating and cooking was positively correlated with respiratory mortality and hospitalization in southern zone counties.

Opis:
Introduction. In animal models, gestational exposure to inorganic arsenic has been associated with higher corticosterone concentration and consequent impairment of stress control in offspring. An equivalent association relating cortisol, a glucocorticoid hormone, in humans has not been previously studied. Objective. The aim of the study was to explore the association between prenatal inorganic arsenic exposure and salivary cortisol in infants from Arica, Chile. Materials and method. A cohort study of 168 mother-child dyads was recruited. In the 2nd trimester of pregnancy, urinary inorganic arsenic was assessed; 18–24 months after delivery, salivary cortisol was measured in the children. Maternal cortisol, maternal depression, stress, and socio-economic status were also evaluated. Results. The adjusted association was estimated with multiple linear regression after evaluating confounding through a directed acyclic graph. Median urinary inorganic arsenic in pregnant women was 14.1 μg/L (IQR: 10.4–21.7) while salivary cortisol in the children was 0.17 μg/L (IQR: 0.11–0.38). Among children from the highest income families (> 614 USD/month), arsenic exposure was associated with salivary cortisol. Children in the third quartile of arsenic exposure had -0.769 units of the logarithm of salivary cortiso, compared with those in the first quartile (p = 0.045). Conclusions. In this sample, prenatal exposure to arsenic was associated with salivary cortisol (third quartile of inorganic arsenic), only in infants belonging the highest income strata (> 614 USD). More studies are needed to confirm these preliminary results.

Opis:
A macroscopic analysis of experimental measurements offuel sprays penetration on evaporating conditions using the Laser Induced Fluorescence Planar technique is presented. A pure fuel and tracers have been used to determine the two-phase process of the spray by characterizing the wavelengths they display when excited by a laser beam. An experimental set-up based on a single cylinder engine [1, 2], an Nd:YAG laser, an image acquisition system and a system of injection common rail have been used to carry out the experimental processes. Experimental results show the behaviour of the vapour phase and liquid phase in the spray under different thermodynamic conditions and injection parameters in the combustion chamber, particularly the work-fluid density and the injection pressure were observed. The measurement of these parameters is of interest to design the combustion chamber geometry and the piston bowl features of modern direct injection Diesel engines. In particularly, the sschematic diagram and main components of the equipment, cross-sectional view of the cylinder head, experimental layout of PLIEF imaging tests and images, examples of the liquid phase and vapour phase penetration, maximum penetration of the liquid and vapour phase as function of the work fluid density, Maximum penetration of the phase as function of the work fluid density, maximum penetration of the liquid and vapour phase as function of the injection pressure are presented in the paper.
