Ferromagnetic resonance of a two-dimensional array of nanomagnets: Effects of surface anisotropy and dipolar interactions
(AMER PHYSICAL SOC, 2018)
We develop an analytical approach for studying the ferromagnetic resonance (FMR) frequency shift due to dipolar interactions and surface effects in two-dimensional arrays of nanomagnets with (effective) uniaxial anisotropy ...
Energetics X-Ray Burst Observation in the Collapse of an X-Pinch Conducted in a Small Capacitive Generator of Low Impedance
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2018)
In this paper, the experimental results of the behavior of an X-pinch plasma conducted in a small capacitive generator of low impedance and inductance are reported. The generator produces currents of the order of 120 kA ...

(ELSEVIER SCIENCE BV, 2018)
The understanding of the ways in which cows with different personalities perceive human contact is essential for improving the quality of the human-animal relationship and therefore the welfare of dairy cows. The general ...
Changes in sperm function and structure after freezing in domestic cat spermatozoa
(WILEY, 2018)
Sperm cryopreservation allows for a long-term storage of genetic. However, changes due to factors as cold shock, osmotic and oxidative stress cause reduction in viability and fertilising ability of frozen/thawed spermatozoa. ...

Objetivo: La finalidad de este estudio fue determinar los cambios en el balance autónomo, la percepción subjetiva del esfuerzo (PSE), y el lactato sanguíneo después de un protocolo de ejercicio aeróbico continuo y uno ...
Positive HER-2 protein expression in circulating prostate cells and micro-metastasis, resistant to androgen blockage but not diethylstilbestrol
(Facultad de Ciencias, 2011)
Introduction : HER-2 expression in prostate cancer is associated with a worse prognosis and is suggested to play a role in androgen resistance. We present a study of HER-2 expression in circulating tumor cells and ...
