Cryopreservation of boar semen in 0.5mL straws at low spermatozoa concentration is better than high concentration to maintain sperm viability
(Revista Pesquisa Veterinaria Brasileira, 2018-09-01)
To date, no studies have been performed evaluating the effect of boar spermatozoa concentration in 0.5mL freezing straws, leading us to examine this question. Each sperm-rich fraction of the ejaculate (n=25) was diluted ...
Selenium restricts cadmium uptake and improve micronutrients and proline concentration in tomato fruits
(2019-03-01)
In order to identify the beneficial effects of Selenium (Se) in tomato (Solanum lycopersicum), genotypes MT and hp1, under Cadmium (Cd) toxicity, the following analyses were performed: Cd and Se concentration and translocation ...
Physiological Acute Response to High-Intensity Intermittent and Moderate-Intensity Continuous 5 km Running Performance: Implications for Training Prescription
(2017-02-25)
The aim of this study was to investigate the physiological responses to moderate-intensity continuous and high-intensity intermittent exercise. Twelve physically active male subjects were recruited and completed a 5-km run ...
Optimization of temperature, sugar concentration, and inoculum size to maximize ethanol production without significant decrease in yeast cell viability
(Springer, 2009-06-01)
Aiming to obtain rapid fermentations with high ethanol yields and a retention of high final viabilities (responses), a 2(3) full-factorial central composite design combined with response surface methodology was employed ...

Suspension and infiltration of copper concentrate in a gravel bed: a flume study to evaluate the fate of a potential spill in a Chilean river
(Springer, 2020)
This paper shows the advances of an experimental study of the spill of copper concentrate into immobile gravel beds. The purposes of this research are to identify the dynamics of the copper concentrate as it spills in ...
Heavy metals concentration insediment of lluta river basin
(Sociedad Chilena de Química, 2018-03)
Northern Chile is characterized by water scarcity. The Lluta River, located in the XV region of Arica and Parinacota, is the one of the main rivers in northern Chile. The elevated levels of metals and metaloids in the river ...
