Soybean is a source of high-quality proteins and fatty acids for animal and human nutrition. To satisfy the national demand of this crop it is necessary to increase the production of soybean by developing or selecting species that are resistant to adverse environmental conditions. Four soybean varieties customarily grown in Mexico were studied in a comparative manner. Each variety was characterized on the basis of impurities, grain integrity, water content, total and free fatty acids content, protein content, and germination capability following the methods and regulations indicated in NMX-FF-089-1994-SCFI, ISTA and AOAC. None of the soybean varieties presented impurities; Huasteca-100 soybean had a lower percentage of immature grains while the UFV-1 variety had the lowest number of grains damaged by microorganisms. Humidity contents were similar in all four soybean varieties (around 7%). The Huasteca-100 variety had some lower protein content while the UFV-1 variety had the maximum (39%). On the contrary, the lipid content was higher in Huasteca-100 and lower in the UFV-1 variety. Based on these results and on the fact that Huasteca 100 was a strong prospect for massive cultivation in Mexico, this variety was considered an adequate substrate to further study the effect of diverse stressing conditions.

The teaching process and the success of learning are closely linked to cognitive and motivational factors. The purpose of this study was to test a multilevel model in higher education students on the relationship between the teaching organization and the dimensions of grit and perceived competence. Participated 3033 students, who answered utility dimension inventories and organization, competition and grit. The results show that at the individual level, the organization by the teaching staff focused on the utility and organization is positively related to the student's scream, this relationship being mediated by the perceived competence. The organizational improvement of the teacher generates student achievements through the positive impact on their competence. [ABSTRACT FROM AUTHOR]

Imagery is a cognitive process that can play an important role in planning and execution of movements or actions. Several instruments have been developed in order to evaluate the ability of Imagery in sport. However, none focused on the kinesthetic, visual internal and visual external modalities. The objective of this study was to translate and validate preliminary for the Portuguese sports population the Movement Imagery Questionnaire-3, determining its initial psychometric qualities through an exploratory factor analysis model that supports it. The sample comprised 176 subjects (N = 176) (N = 134 male, female N = 42) with a mean age of 20.8 years (SD = 5.94), consisting of soccer (N = 113), basketball (N = 43) and tennis (N = 20) players. Initially it was found that the procedures of translation and adaptation originated a Portuguese version MIQ - 3 similar to the original version. Secondly we found that the psychometric qualities prove their suitability of adaptation performed, demonstrating that its factor structure is the same as the original version (12 items grouped into 3 factors, with 4 items each factor), with quite acceptable levels of validity and reliability (Cronbach's alpha: 0.88 to MIQ - 3, 0.79 for the three modalities), concluding that this questionnaire can be used to assess Imagery capacity in Portuguese athletes.
