During the last decade, rural extension has received interest as being a key tool for rural development. Despite rural extension being affected by many psychosocial processes, psychology has made scarce contributions to it. An investigation was conducted with the aim of gaining knowledge of rural extensionists’ expectations of psychology, as well as to contribute to shaping community psychologists’ role in the context of rural extension . 652 extensionists from 12 Latin American countries were surveyed. The survey included closed socio-demographic questions as well as open ones addressing extension practice and psychologists’ potential contributions. 90.6 % of surveyed extensionists considered psychology could help them improve their practice. Most mentioned areas of contribution go in line with community psychology, including managing farmers groups, facilitating participatory processes and training extensionists; while others, such as the expectation of changing farmers’ mindset and increasing the adoption of external technologies, go against its principles. Thus, in some cases, extensionists’ expectations could help generate an interesting interaction between community psychology and rural extension, while in others, they need to be put up for discussion. In brief, community psychology has the potential to contribute to rural extension, but it needs to acknowledge extension practice as an interesting area for intervention. © 2015, Society for Community Research and Action.

This article provides a detailed study of the structure and bonding in closo-borane cluster compounds X 2B 3H 3 (X = BH -, P, SiH, CH, N), with particular emphasis on the description of the electron distribution using the topology of the quantum many-body effectively unpaired density. The close relationship observed between the critical points of this quantity and the localization of the electron cloud allows us to characterize the nonclassical bonding patterns of these systems. The obtained results confirm the suitability of the local rule to detect three-center two-electron bonds, which was conjectured in our previous study on boron hydrides. © 2011 American Chemical Society.

Maillard reaction (MR) is one of the most studied methods to improve the functional properties of proteins so as to turn them into better food ingredients. The mechanical properties of whey protein isolate (WPI)/dextran (DX) mixed and conjugate (obtained by MR) gels were investigated. Dextrans with different molecular weight (MW: 6, 40 and 70 kDa) and various concentrations (3.6, 7.2 and 10.8% w/w) were studied. WPI/DX conjugates were obtained by controlled dry heating (60 °C and 0.63 aw for 5 days). A decrease in the content of free amino group and an increase in colour parameters of WPI/DX conjugate systems revealed that MR had a higher progress for the lowest DX molecular weight and for the highest DX concentration. The mechanical properties (at the fracture point) of WPI/DX mixed gels were affected by DX concentration. On the other hand, unlike mixed gels, WPI/DX conjugate gels showed no fracture under the test conditions (80% deformation). © 2013 Elsevier Ltd. Source

We report a study of the structure of (+)-catechin, which belongs to the family of the flavan-3-ols-one of the five most widely distributed phenolic groups. The biological activities and pharmaceutical utility of these compounds are related to antioxidant activity due to their ability to scavenge free radicals. A breakthrough in the study of the conformational space of this compound, so far absent in the literature, is presented herein. A detailed analysis of the electronic distribution, charge delocalization effects, and stereoelectronic effects is presented following application of the theory of atoms in molecules (AIM) and natural bond orbital analysis. The stability order, and the effects of electron delocalization in the structures were analyzed in depth. The molecular electrostatic potential (MEP) was also obtained, assessing changes in the electronic distribution in aqueous solution, the effects of the solvent on the intrinsic electronic properties, and molecular geometry. The effect of the aqueous solvent on MEP was also quantified, and rationalized by charge delocalization mechanisms, relating them to structural changes and topological properties of the electronic charge density. To further analyze the effects of the aqueous solvent, as well as investigating the molecular and structural properties of these compounds in a biological environment, the polarizabilities for all conformers characterized were also calculated. All results were interpreted on the basis of our accumulated knowledge on (4α→6", 2α→O→1")-phenylflavans in previous reports, thus enriching and deepening the analysis of both types of structure.

The effect of Maillard reaction on the mechanical properties of whey protein isolate (WPI) heat-induced gels was evaluated. WPI and dextran (15-25 kDa) conjugates were obtained by controlled dry heating during storage at 60 °C and 63% relative humidity for 2, 5 and 9 days. Changes in browning intensity and content of free amino groups were used to estimate the Maillard reaction. A decrease in free amino groups of WPI was observed when increasing polysaccharide concentration and reaction time. An increase in both a* and b* CIE Lab colour parameters indicated the development of a reddish-brown colour, typical of the Maillard reaction. Uniaxial compression and stress relaxation tests were performed to measure the mechanical properties of mixed and conjugate gels. Maillard reaction significantly modified the mechanical properties of WPI/DX gels, and even prevented fracture when conjugate gels were subjected to 80% deformation in uniaxial compression test. © 2012 Elsevier Ltd.
