A qualidade da vinculação é fundamental para o desenvolvimento das crianças e adolescentes e tem uma enorme importância tanto a nível social como a nível emocional O presente estudo teve como objetivo averiguar a associação entre a qualidade da vinculação e os comportamentos sociais entre adolescentes institucionalizados que constituíram a sua amostra (34 jovens, de ambos os sexos e com idades compreendidas entre os 11 e os 18 anos). O protocolo de investigação incluiu um questionário sociodemográfico e a versão portuguesa do Inventory of parent and peer attachment (IPPA, Armsden & Greenberg, 1987). Os resultados dão conta da perceção normativa dos comportamentos sociais, a despeito de se tratar de uma população de adolescentes institucionalizados. Relativamente à qualidade da vinculação, este estudo dá conta que, apesar da aparente instabilidade da retaguarda familiar, uma parte destes adolescentes tem, ainda assim, a perceção de uma vinculação segura aos pais. / The quality of attachment is essential for the healthy development of children and adolescents, both socially and emotionally. The goal of this study was to analyze the eventual association between the quality of attachment and social behaviors among the institutionalized adolescents in study (34 adolescents from both genders aged 11 to 18 years-old). The research protocol included a social-demographic questionnaire and the Portuguese language version of "Inventory of parent and peer attachment (IPPA, Armsden & Greenberg, 1987). The results show that the perception of social behavior among these adolescents is normative, despite their institutionalization. In what relates to attachment data shows that, regardless of the apparent disorganization of the familial background, these adolescents have the perception of a secure attachment to their parents.

The present study has got as its aim to show how the impressions management is being used by the hotels in Paraiba State. For that, the dramma or role play perspective has been adopted as a model for service management. From the theater metaphor, the physical environment and its components can be seen as a scenery of the service show. We conduct the reader to notice the importance of the consummer about the service quality demand and its influence on his satisfaction. A methodology with exploring and qualifying nature has been adopted by using the analyses of content technique in interviews applied to hotel managers lebeled as having 4 and 5 stars in the State, trying to check how impression management takes place, identifying impression management tools used in relation to the physical evidences and to contacting people, as well as checking managers views in the survey about the use of impression management for client satisfaction make. The information revealed that managers, maybe for being unaware about impression management theory, haven t considered neither the physical evidences yet, nor contacting people as marketing tools. About the physical evidences, we could see that hotels take actions in a pulverized way referring to environment decoration and colors, however there isn t a global usage of physical evidences to highlight the service. Contacting people by their turn, receive better importance and attention. It was possible to make sure that managers are aware about the influence of the employee over the attendance quality. This way, we may come into a conclusion that impression management at Paraiba hotels has been under used, as long as managers seem to be, most times, turned to actions related to contacting people, not having realized the planning importance and national-wide use of service scenery in a genaral way yet

The use of inputs containing phosphites have been presenting results in many studies, taking on importance to the control of diseases in some cultures and demonstrating the resistance induction in seedlings, with ability to activate defense mechanisms, conferring protection to plants against microorganisms. The soybean crop is recognized for its importance in providing grains and derivatives for human consumption, animal, production of biofuels, pharmaceuticals, among others. Positive results obtained through studies based on resistance inducers in some cultures arouse the interest for further study. The objective of this study was to evaluate the effect of potassium phosphites on the resistance induction and treatment of soybean seeds. Therefore were conducted four laboratory studies at the Federal Technological University of Paraná, Campus of Dois Vizinhos. In the first study it was evaluated the quality attributes of the seeds and the resistance induction as seed treatment. Then it was verified that phosphites have action upon the seedlings metabolism in due to seed treatment, having the phosphite Reforce® contributed to seed quality attributes and phosphites FitofosK® and Fitofos K Plus® induced the resistance increasing the activity of β-1,3-glucanase. In the second study it was evaluated the the resistance induction in soybean cotyledons, in which the phosphites demonstrated induction potential of phytoalexin gliceolin. In the third study It was evaluated the soybean seed health treated with potassium phosphites.. it was observed that the phosphites reduced the incidence of many fungi on seeds, especially of storage fungi like Aspergillus sp. and Fusarium semitectum. In the fourth study it was evaluated the in vitro effect of potassium phosphites on pathogenic fungi of the culture. And it was found direct action of phosphites on the mycelial growth of Fusarium semitectum, Pythium sp. and Sclerotinia sclerotiorum. Based on these results, we concluded that potassium phosphites have potential in seeds treatment, as resistance inducer and on in vitro control of phytopathogens.

The use of biopolymers that help to fix pesticides efficiently and degrade easily without harming the environment, and still improve the physiological performance of field soybean seed may bring contributions to the soybean yield. This study aimed to evaluate the effect of cassava starch polymers (AM), sodium alginate (ALG) and polyvinyl alcohol (PVOH), in the concentrations 2, 4 and 6 g / 100 ml of solution, in the physiological attributes of seeds soy, seed speed soaking and performance of soybean seeds after three months of storage. The soybean variety used was the NK 7059 RR. The experimental design used for the three studies was a factorial with 48 experimental units: 3 polymers (AM, ALG and PVOH), 4 different concentrations (0%, 2%, 4% and 6%), with four replications, in a completely randomized design. It was observed the level of significance of the factors and their interactions, applying the test F. The polymers were evaluated by the Tukey test at 5% probability, and the concentrations were evaluated by polynomial regression. The witness obtained better results for most variables studied. Among the polymers, the best coating was observed PVOH because it was the less viscous polymer and visually not served as a substrate for microorganisms. However, also, satisfactory results were obtained for the AM and ALG polymers at a concentration of 2%. There was not interference of the polymers studied with regard to reduction of imbibition rate of soybean seeds. The hydrophilicity of polymers, mainly the AM and ALG accelerated soaking seeds harming germination at concentrations 4% and 6%. In general, the higher the concentration of polymers tended to worse results.

Objetivo: Avaliar a relação entre experiência de cárie, qualidade de vida relacionada à saúde bucal (QVRSB) e fatores socioeconômicos em escolares de rede municipal. Métodos: Este estudo, de corte transversal, realizado em um município paulista a partir de um levantamento de saúde bucal do ano de 2012, incluiu 142 escolares com 12 anos completos para avaliação da QVRSB por meio do Child Perceptions Questionnaire (CPQ11-14) e de fatores socioeconômicos (escolaridade dos pais, renda, número de cômodos e número de pessoas que habitam o domicílio). A experiência de cárie foi avaliada e expressa pelo índice CPOD e ceo-d (número de dentes cariados, perdidos e obturados na dentição permanente e decídua, respectivamente). A análise consistiu de estatística descritiva, uso dos testes Qui-quadrado, Mann-Whitney e correlação de Spearman. Resultados: Do total, 58,5% (n=83) dos escolares apresentaram experiência de cárie (CPOD+ceo-d≥1), os quais também apresentaram maiores escores na percepção global em saúde bucal (2,6±0,9 x 2,1±0,8), na escala total (33,0±22,6 x 21,9±14,5) e nos domínios bem-estar emocional (11,4±8,6 x 6,6±5,8) e bem-estar social (7,7±8,2 x 4,4±4,9) quando comparados àqueles sem experiência de cárie. Observouse também correlação positiva significativa entre o número de pessoas que habitavam o domicílio e o índice CPOD/ceo-d (r=0,2670; p=0,003). Conclusão: A experiência de cárie relacionou-se com uma percepção negativa da saúde bucal, principalmente nos aspectos emocional e social, e com o número de pessoas que habitavam o domicílio.

Four different sponge species were screened using Ouchterlony agarose gel and immunodiffusion tests to identify cross-reactivity with the polyclonal antibody IgG anti-deglicosilated CvL, a lectin from Cliona varians. Crude extract from the sponge Cinachyrella apion showed cross-reactivity and also a strong haemmaglutinating activity towards human erythrocytes of all ABO groups. Thus, it was submitted to acetone fractionation, IgG anti-deglicosilated CvL Sepharose affinity chromatography, and Fast Protein Liquid Chromatography (FPLC-AKTA) gel filtration on a Superose 6 10 300 column to purify a novel lectin. C. apion lectin (CaL) agglutinated all types of human erythrocytes with preference for papainized type A and O erythrocytes. The haemagglutinating activity is independent of Ca2+, Mg2+ and Mn2+ ions, and it was strongly inhibited by the disaccharide D-lactose, up to a minimum concentration of 6.25 mM. CaL molecular mass determined by FPLC-AKTA gel filtration on a Superose 12 10 300 column and SDS gel electrophoresis was approximately 124 kDa, consisting of eight subunits of 15.5 kDa, assembled by hydrophobic interactions. The lectin was relatively heat- and pH-stable. Leishmania chagasi romastigotes were agglutinated by CaL, indicating that lactose receptors could be presented in this parasite stage. These findings are indicative of the physiological defense roles of CaL and its possible use in the antibiosis of pathogenic protozoa

A comunidade bentônica exerce um importante papel em processos ecológicos e eco toxicológico em ambientes aquáticos. Esta comunidade reflete alterações físicas, químicas e ecológicas ocorridas no ambiente aquático, funcionando como indicador de alterações da qualidade ambiental. É constituída, em sua grande parte, de organismos sedentários ou sésseis de vida relativamente longa (RESH, 1993; ROSENBERG e RESH, 1993) indicando o estado trófico passado e presente e os efeitos de poluentes nos corpos d?água, armazenando informações por períodos mais longos. O cultivo de peixes em tanques-rede vem sendo cada vez mais utilizado. O aumento desta atividade faz com que se torne necessária o desenvolvimento e aplicação de tecnologias de baixo custo e práticas para o monitoramento e avaliação da qualidade da água em reservatórios rurais.Em vista disso, coletores do tipo substrato artificial podem ser utilizados para esta finalidade, possuindo a vantagem de reduzir bastante ocusto de avaliação da qualidade da água por empregarem materiais de fácil aquisição e confecção.
