Abstract This work aims to evaluate, at different stages, the productive performance, carcass quality, and intestinal biometry of European quails (Coturnix coturnix Coturnix), consuming diets with increasing levels of seaweed bran (Sargassum sp). A total of 240 European quail chicks (Coturnix coturnix Coturnix) were distributed in a completely randomized design, with four levels of bran inclusion (0.0, 2.5, 5.0, and 7.5%), 6 replications with 10 birds in each experimental plot. In the period from 1 to 21 days, the feed intake of the control group was higher, with lower water consumption. In the period from 22 to 42 days, feed and water consumption increased with the inclusion of seaweed, but with a reduction in weight gain. In the total period, water consumption was higher at the level of 2.5 and 7.5%, with lower consumption in the control group, with a small reduction in slaughter and carcass weight with the inclusion of bran. There was no difference (P > 0.05) in carcass quality and intestinal biometry. We recommended the inclusion of up to 7.5% of sargassum meal in the diet of European quails at all stages, without compromising its productive performance, carcass quality, and intestinal biometry.

ABSTRACT The aim of the present study was to evaluate the effect of sanitizers on physicochemical characteristics, sanitary quality of ‘Paluma’ guava fruits during storage and in vitro control of Colletotrichum sp. Guavas ‘Paluma’ were treated with the sanitizers acetic acid, ascorbic acid, sodium hypochlorite, peracetic acid, hydrogen peroxide and thiabendazole fungicide, besides control (distilled water). Evaluations included fresh mass loss, firmness, pH, titratable acidity (TA), soluble solids (SS), SS/TA ratio, sanitary quality and in vitro control of Colletotrichum sp. The design was completely randomized, in a split-plot scheme, including seven treatments and five periods (three days), and four replicates of three fruits each. The sanitizers played an effective role in controlling mass loss and firmness of stored fruits. The pH of fruits was influenced by hydrogen peroxide (6th day), acetic acid and sodium hypochlorite (15th day). Acetic and peracetic acids reduced ascorbic acid loss in the fruits, indicating that sanitizers can be an alternative to increase the shelf life of fruits. Considering sanitary control, acetic acid and thiabendazole fungicide inhibited the growth of Colletotrichum sp. Acetic and peracetic acids and thiabendazole completely inhibited the growth of both isolates of Colletotrichum sp.

RESUMO O trabalho teve por objetivo avaliar o efeito de sanitizantes sobre as características físico-químicas, qualidade sanitária de frutos da goiabeira ‘Paluma’ durante o armazenamento e controle in vitro de Colletotrichum sp. As goiabas ‘Paluma’ foram tratadas com os sanitizantes ácido acético, ácido ascórbico, hipoclorito de sódio, ácido paracético, peróxido de hidrogênio e fungicida tiabendazol e controle (água destilada). Foram avaliadas a perda de massa fresca, firmeza, pH, acidez titulável (AT), sólidos solúveis (SS), relação SS/AT, qualidade sanitária e controle in vitro de Colletotrichum sp. O delineamento foi inteiramente casualizado, em esquema de parcelas subdivididas no tempo, sendo sete tratamentos e cinco períodos (três dias), com quatro repetições de três frutos cada. Os sanitizantes desempenharam papel efetivo no controle da perda de massa e firmeza dos frutos armazenados. O pH dos frutos foi influenciado pelo peróxido de hidrogênio (6º dia), ácido acético e hipoclorito de sódio (15º dia). Ácidos acético e paracético reduziram a perda de ácido ascórbico dos frutos, indicando que os sanitizantes podem ser uma alternativa para aumentar a vida útil dos frutos. No controle sanitário, o ácido acético e o fungicida tiabendazol inibiram o crescimento de Colletotrichum sp. Os ácidos acético e paracético e o tiabendazol, inibiram totalmente o crescimento de ambos isolados do Colletotrichum sp.

ABSTRACT OBJECTIVE: To evaluate the effects of resistance exercise applied early after coronary artery bypass grafting. METHODS: It is a randomized controlled trial with 34 patients undergoing coronary artery bypass grafting between August 2013 and May 2014. Patients were randomized into two groups by simple draw: a control group (n=17), who received conventional physical therapy and an intervention group (n=17), who received, additionally, resistance exercise. Pulmonary function and functional capacity were evaluated in preoperative period and hospital discharge by spirometry and the six-minute walk test. For statistical analysis, we used the following tests: Shapiro-Wilk, Mann-Whitney, Student'st and Fisher's exact. Variables withP<0.05 were considered significant. RESULTS: Groups were homogeneous in terms of demographic, clinical and surgical variables. Resistance exercise exerted no effect on pulmonary function of intervention group compared to control group. However, intervention group maintained functional capacity at hospital discharge measured by percentage of predict distance in 6MWT (54.122.7% vs. 52.515.5%,P=0.42), while control group had a significant decrease (59.211.1% vs. 50.69.9%, P<0.016). CONCLUSION: Our results indicate that resistance exercise, applied early, may promote maintenance of functional capacity on coronary artery bypass grafting patients, having no impact on pulmonary function when compared to conventional physical therapy.

Considerando o uso das novas tecnologias nos tempos atuais, especificamente de programas que, tecnicamente, são chamados de softwares e sua importância no ambiente educacional, objetivou-se neste artigo, analisar as contribuições da avaliação como instrumento mediador da aprendizagem em softwares educativos, especificamente de línguas estrangeiras (Espanhol e Inglês), no sentido de verificar quais concepções de avaliação estão subjacentes às suas propostas de aprendizagem, assim como examinar em que grau a dimensão da interface do programa favorece a aprendizagem do usuário, no que diz respeito à facilidade de uso, ao conteúdo, aos graus de organização dos conteúdos e de interação entre o que foi ensinado e o que é solicitado nos exercícios, ao exame final de cada lição, à metodologia e aos critérios de avaliação da aprendizagem.

Considering the use of new technologies in current times, specifically programs that technically are called software and its importance in the educational environment, the intention of this article is to conduct an study about the contributions of evaluation as a mediating instrument in the learning process, analyzing foreign language educational softwares (Spanish and English), in order to determine what conceptions of evaluation underlie their teaching proposals, and to examine to what extent the size of the program interface will encourage user acquisition in regard to ease of use, the content, the degree of content organization and interaction between what was taught and what is required in the exercises, the test after each lesson, the methodology and criteria for learning assessment.
