Cíntia Tarabal Oliveira, érika Maria Roel Gutierrez, Márcio Caliari, Márcia Regina Pereira Monteiro, Renata Adriana Labanca, Raquel Linhares Carreira
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.612194
Abstract: Mixtures of cereals and legumes result in products with higher content of high biological value proteins. The thermoplastic extrusion promotes the transformation of chemical, physical and nutritional characteristics of the food such as starch gelatinization and promotes the inactivation of anti-nutritional compounds and enzymes. This study aimed to develop products extruded using broken rice and lupine and to evaluate the physical and chemical characteristics of those products. The expansion index (EI), water solubility (WSI), water absorption (WAI), texture and color were determined for the extruded rice, and Scanning Electron Microscopy (SEM) of the extruded rice was also performed. As the rice concentration in the mixture increased, the EI, WSI and WAI values as well as the a* color parameter were increased too, and the brightness was reduced. An increase in the levels of essential amino acids with the addition of lupine grain to the extrudates was observed. SEM analysis identified intact loose starch granules or pellets in the raw materials, and the extruded samples showed a compact and amorphous shape without apparent starch granules. Due to the structural changes and reduced expansion rate of the extruded mixture prepared with lupine and rice grits, use of the extruded mixtures as snacks would not be suitable. However, these mixtures could be used in pre-gelatinized flour to formulate various products to increase the protein level.

Abstract: yolk color and egg white (albumen) cleanliness and viscosity are important parameters by which consumers judge the quality of eggs. this study aimed to investigate changes in albumen viscosity during storage of eggs for up to 36 days from two different commercial laying hen strains (carijo barbada and isa brown) fed a diet containing annatto (1.5 and 2.0%) or a synthetic additive without synthetic colorants (control). analyses of humidity, albumen height, ph, viscosity, foam formation, and stability were carried out on eggs. carijo barbada strain had smaller albumen, lower humidity and higher egg white viscosity than isa brown strain; however, with storage, viscosity lowered significantly on both strains. initially, the addition of 2.0% of annatto or a synthetic additive increased viscosity in both strains, but with storage only the control maintained longer viscosity. lower viscosity did not change foam density and stability.

Open Journal of Nursing (OJN) , 2016, DOI: 10.4236/ojn.2016.64027
Abstract: Sound generated in a ward can be classified into 1) generated by medical staff, 2) generated by patients and their visitors, and 3) others, such as from in-hospital broadcasting microphones and nurse calls. Among these sounds, the incidence from medical staff, in particular, is reportedly high. The study objective is to investigate whether sound awareness is effective in regulating the sound environment even in a busy situation, such as in a real clinical setting, and to examine the extent to which sound awareness affects sound level. Nursing students were asked to perform a series of nursing activities in a pseudo-ward, and the changes in the sound level generated during the nursing activities with or without time and sound awareness were examined. Under varying experimental conditions, the sound and time levels associated with the nursing activities were measured in the following order: condition 1, without sound or time awareness; condition 2, with time awareness but without sound awareness; and condition 3, with both sound and time awareness. The time to perform nursing activities was longer with sound awareness. However, when aware of time only, the sound level from nursing activities rose by 2.3 dB, whereas when aware of both time and sound, the sound level dropped by 3.0 dB. With both time and sound awareness, there is a distinct drop in the sound level from nursing activities, such as wagon handling, handling of items (trays, bowls), working at the sink, and opening and closing the microwave oven door. These results suggest that even in a pseudo-clinical setting it is possible to regulate the environmental sound through the environmental sound awareness of the medical staff, resulting in a drop in the sound level generated while performing nursing activities.
Coding Issues in Cognitive Mapping of Games  [PDF]
Roel Popping
Open Journal of Political Science (OJPS) , 2013, DOI: 10.4236/ojps.2013.31003
Abstract:

In text analysis studies coders have to make qualitative decisions. These decisions are based on interpretations of the texts under study. In such situations it is very helpful to have coding rules. These do not only help as an aid to the coder, but are also useful for readers of the research report that will follow. The rules make visible in considerable extent how the coding task has been performed, they take care of transparency. This contribution focuses on motions that have been treated in the Dutch House of Representatives. Motions usually contain information on why they are needed, the proposing member usually also tells about it. There is a discussion with the secretary, who is supposed to put the motion into effect if it is accepted. The secretary even has to give an advice. It is assumed that under these discussion(s) a cognitive map containing some game theoretic representation can be found. Rules are discussed that are used to code the types of maps that might be found.

Abstract: obesity is a public health issue with relevant social determinants in its etiology and where interventions with teenagers encounter complex biopsychological conditions. this study evaluated intervention in nutritional education through a problem-posing approach with 22 obese teenagers, treated collectively and individually for eight months. speech acts were collected through the use of word cards, observer recording, and tape-recording. the study adopted a qualitative methodology, and the approach involved content analysis. problem-posing facilitated changes in eating behavior, triggering reflections on nutritional practices, family circumstances, social stigma, interaction with health professionals, and religion. teenagers under individual care posed problems more effectively in relation to eating, while those under collective care posed problems in relation to family and psychological issues, with effective qualitative eating changes in both groups. the intervention helped teenagers understand their life history and determinants of eating behaviors, spontaneously implementing eating changes and making them aware of possibilities for maintaining the new practices and autonomously exercising their role as protagonists in their own health care.
