Características reológicas e sensoriais de bebidas lácteas funcionais

This research studied the effects of the independent variables whey protein concentrate - WPC (3.0; 3.5; 4.0%), skimmed milk powder - SMP (4.0; 5.0; 6.0%), and isolated soy protein - IPS (1.5; 2.0; 2.5%) on the rheological and sensorial characteristics of functional dairy beverages. In all tests 7% of sucrose was added to the ingredients. The rheological parameters were obtained in duplicate at the temperature of 10° C using a cone and plate rheometer, and fitted to the Power law model. The samples revealed a non-Newtonian fluid behavior both in the upward and downward curves, typical of a tixotropic fluid. The dairy beverages were submitted to a sensory analysis by a group of fifty untrained tasters who used a hedonic scale of nine points, the extremes being 1 - disliked extremely and 9 - liked extremely, in order to evaluate the following parameters: general acceptability; appearance and color; consistency; taste and aroma. The dairy beverage produced with 3% WPC, 6% SMP and 1.5% IPS, (treatment 3), was the one that obtained the best average score for those attributes and was preferred by the tasters. The variables SMP and IPS and the interaction between WPC and SMP presented a positive effect on the sensory consistency attributes: the higher amount of those ingredients in the formula the more the tasters liked the consistency.

Geração de padrões de corte n-grupos para a indústria moveleira

Neste artigo são apresentadas propostas de soluções para o problema de geração de padrões de corte n-grupos para o corte da matéria-prima na indústria moveleira. Este problema NP-difícil aparece em diversos outros processos industriais que incluem o corte de painéis retangulares grandes de tamanho padrão em retângulos menores. O planejamento dos cortes é um aspecto importante do planejamento da produção nestas indústrias, pois efeitos negativos tais como o perda de matériaprima e tempo de preparo da máquina de corte podem ser minimizados, diminuindo assim os custos de produção. É estudada a eficiência de modelos lineares inteiros para resolver o problema do corte guilhotinado bidimensional propostos em [33,34], bem como o seu uso na geração de colunas para o problema de corte de estoque. São usados dados reais de uma fábrica de móveis de pequeno porte característica do pólo moveleiro de Votuporanga/SP. Os resultados obtidos indicam que as estratégias propostas geram perdas dentro dos requisitos exigidos pela fábrica. © SPM.

Analisando imagens: Um ensaio sobre a criação de fontes narrativas para compreender os Grupos Escolares

This paper is an essay on how photos can be analysed and used to create narratives which may serve as resources for historical studies about school practices. As an exercise, we deal with six old photographs taken in Grupos Escolares, a Brazilian educational institution founded in the last decade of the 19th Century and extinguished in the 1970's. According to some authors, these schools represented the beginning of the public educational system in Brazil.

O papel das argininas alfa-92 e alfa-141 na regulação das propriedades funcionais de hemoglobinas por íons cloreto

The oxygenation of human Hb (HbA) demands a three state model: two deoxy states To and Tx, free and complexed with anions respectively, and an oxy R state. The regulation between these states is modulated by the presence of anions, such as chloride, that binds to T state. The b inding if chloride, however, remains controversial. The aim of this work is the study of arginines 92a (a1ß2 interface) and 141a (C-terminal) as chloride binding sites. To investigate that, we have studied 92 and 141 site directed mutant species: natural mutants Hb J-Cape-Town (R92Q), desArg (R141Δ), Chesapeake (R92L), and the constructed Chesapeake desArg (R92L,141Δ). We expressed Hbs in Escherichia coli and purified. Through oxygen binding curves we measured affinity and cooperativity, in function of water effect and Bohr effect in presence and absence of chloride. Structural features were obtained through 1H NMR spectroscopy Oxygen binding properties and Bohr effect measured indicated a higher affinity and lower cooperativity in absence and presence of chloride for all mutants. Structural changes represent functional aspects of mutant Hbs, such as a significant rise in affinity or a change in cooperativity. Water activity studies conducted as a function of chloride concentration showed that the only Hb desArg follows the thre state model. The other mutant Hbs do not exhibit the Tx state, a fact confirmed by the number of water molecules bound to each Hb during the deoxy-oxy transition. This behavior suggests that the Arginine 92 site could be responsible for chloride binding to Hb, since oxygenation of 92 mutant Hbs cannot be adjusted by the three state model. However, Bohr effect showed that all mutant Hbs released~1 proton in chloride presence, different from HbA that releases ~2, suggesting a role for 141 arginine in the tertiary and quaternary Bohr effect.

Somatotropina bovina recombinante (rbST) e grupos raciais sobre a precocidade reprodutiva de cabras

The objective of this work was to evaluate the effect of rbST and breed group on the reproductive precocity of goat females. Eighteen goat females of Alpine breed and breed groups 1/2 Boer + 1/2 Alpine (1/2 BA) and 3/4 Boer + 1/4 Alpine (3/4 BA) were used, distributed in two homogeneous groups of 9 animals, received treatments: Group 1-0,3 mg of recombinant bovine somatotropin by kg of body weight each 14 days and Group 2 - control and aplication was subcutaneous. Animals from control group received saline solution in same dose and interval. The administration of hormone begins after weaning of animals (approximate 45 days of age). The train of the development of females was made by weighed weekly until reaching the previously definitive weight of 30 kg of live weight (LW). For evaluation of the reproductive performance it was made observations of the signals related to the oestrus. The characteristics evaluated was: Weight gain at born until weaning, weaning at 120 days, 150 and 180 days of age, weight to the oestrus, age to the rutting and the 30 age to kg of LW. It was not observed influence of growth hormone and the breed group for weight to rutting, age to rutting and age to reach 30 kg LW. The use of rbST in growth females did not modify the parameters of sexual precocity.

Demanda por grupos, psicologia e controle

Este artigo traz uma reflexão sobre uma capacitação para o trabalho grupal, destinado às equipes das UBSs (Unidades Básica de Saúde) do SUS (Sistema Único de Saúde) e agentes comunitários de saúde de um município do interior do Estado de São Paulo. Trata-se de analisar o pedido explicitado pela equipe, de mostrar a reflexão a respeito desse pedido, as circunstâncias dos problemas colocados, a experiência dos vários trabalhadores da equipe e a escuta do que se passa do lado da população. Parar para ouvir os parceiros do trabalho e refletir sobre a intervenção fez a equipe trabalhar sua sensibilidade diante das questões da população, do que vem a ser saúde e poder assumir outra postura que não seja a de servir ao controle da população e trabalhar para a construção da sociedade de controle.

Intervenções em linguagem escrita: Uma revisão da literatura com vistas à redução dos transtornos funcionais de aprendizagem

The importance reading and writing and being able to use these skills in a variety of situations is an absolute reality. In our society in which reading and writing are widely used, Brazil still faces severe problems with literacy, as revealed in literacy statistics and in the large number of students with learning disabilities. Thus, our text aims to present a survey of the research that focuses on intervention programs highlighting the needs of this group, with special attention on the use of narrative or storytelling. Specific criteria were established, the main one being the period of the publications (2000 to 2010). The results of the analysis of 15 texts showed that intervention is the most neglected area. International literature presents concerns related to scientific rigor or greater control of variables related to ongoing programs, as well as measures for generalizing the effective use of these programs, within verbal communities, with special focus on schools. Our revision enabled us to conclude that, even though production on written language is large, international literature is much more expressive with reference to intervention programs. Furthermore, in both national and international literature, production concerning the understanding of written language processes of acquisition and development prevails.

Agentes tróficos na dieta de leitões desmamados sobre a atividade das enzimas digestivas e o desempenho

It was evaluated the effect of the addition of glutamine, polyunsaturated fatty acids or cellular wall of yeast to the diet of weaned pigs on the activity of the pancreatic enzymes (lipase, amylase and trypsin) and the intestinal mucous membrane (dipeptidase, sucrase and maltase) and on the performance. Forty-five weaned pigs were used and distributed in a randomized block design, in factorial outline, with four diets (T1 - basal diet (BD); T2 - BR + 1% glutamine; T3 - BD + 0,2% cellular wall of yeast; T4 - BD + 5% fish oil) and two slaughter ages (seven and 14 days post weaning). The performance was measured in the first two weeks post-weaning. The addition of 1% glutamine in the diet of pigs increased the specific and total activity of the amylase, and total activity of the trypsin in the second week post weaning. The others supplements not change the activity of the digestive enzymes in the pigs. Also an increase was observed in the total activity of the lipase, and specific activity of the trypsin and maltase in function of the age post-weaning. In general, the activities of the digestive enzymes were correlated positively, except for the dipeptidase that was not correlated with any other enzyme. Positive correlation was observed between weight gain and activity of the lipase and of the amylase. The supplements included in the diet not influence the performance of weaned pigs.
