Understanding health as physical and mental well-being, there is a lack of health literacy in Latin America, especially in mental health. Therefore, our strategy looks forward to providing mental health literacy to teachers, in order to train in psychological first aid within school environments. This initiative will have face-to-face training and...

Introducción: Existen varias técnicas de corregir la luxación atloidoaxoidea por artritis reumatoide (AR); Gallie, en 1939, utilizó un abordaje posterior y fijación de injerto óseo con cable sublaminar de C1 a C2, con bajo índice de fusión y estabilidad. Brooks, incrementó el índice de fusión y de estabilidad rotacional. Magerl y Seeman, utilizaron...

The composition of fatty acids in liver and semitendinous and longissimus muscle tissue in both cattle and buffalo were compared. The fat was extracted from liophilized tissue samples and the extracted fatty acids were then methyl esterified and analyzed by gas chromatography. Buffalo liver had greater (P<0.05) levels of linoleic (C18:1, n-9), α-li...

A study was conducted to investigate the effect of the dietary inclusion of three levels of trout by-product silage (TBPS, 0, 10 and 20%) on broiler chicken practical finisher diets. The variables evaluated were performance parameters, total fat content, abdominal fat content, and fatty acid composition of thigh muscle, breast muscle, and liver. Th...

The electrochemical behavior of magnesium under the conditions imposed by two standards, ASTM G 97-89 and NOM K 109-1977 was investigated by plotting current-voltage curves (Tafel diagrams) and by measurement of electrochemical impedance. Under ASTM conditions, the increase in protection with immersion lime seems to provide evidence for the existen...

The electrochemical behavior of a magnesium galvanic anode in an aerated 5 g/L calcium sulfate + 0.1 g/L magnesium hydroxide solution was investigated by measuring electrochemical impedance under the conditions of ASTM Test Method G 97-89. Impedance spectra showed the capacitance of a porous layer (C{sub po}) in the high-frequency region, the resis...
