O objetivo deste estudo foi avaliar o efeito da termoterapia (56 ºC por 6 min) e quimioterapia (propiconazole 250 ml.l-1) associado com temperatura de armazenamento (temperatura ambiente, 18 ºC e 13 ºC) no controle de podridões de bananas (Musa spp.) 'Prata-Anã' (AAB) em pós-colheita. Os tratamentos apresentaram diferenças significativas na percentagem de área lesionada por fruto, perda de peso e coloração externa da casca em todas as temperaturas de armazenamento. A quimioterapia e a combinação termoterapia e quimioterapia evitaram a manifestação de podridões nas três condições de armazenamento, enquanto a termoterapia reduziu a percentagem de área lesionada por fruto de 98% para 11% em temperatura ambiente, de 8% para 7% em 18 ºC e de 10% para 0% em 13 ºC, sendo mais eficiente sob a temperatura de 13 ºC. Frutos não tratados perderam 25%, 10% e 3% de peso e atingiram a cor 7, 5 e 1 em temperatura ambiente, 18 ºC e 13 ºC, respectivamente. Frutos tratados com termoterapia e quimioterapia perderam 24, 11 e 5% e 20, 10 e 3%, e atingiram índice médio de cor 4 e 3,5, respectivamente. O período de conservação foi estendido para 18, 24 e 45 dias em temperatura ambiente, 18 ºC e 13 ºC, respectivamente. A combinação dos métodos evitou a manifestação de podridões, reduziu a perda de peso e manteve a cor da casca e a qualidade dos frutos.

The aim of this experiment was to evaluate the hypothesis that the M. amazonicum prawns accept feeding in trays. Six ponds were stocked with 10 juveniles II (1.2 +/- 0.7 g) per m(2) in 02/14/2003. An entirely randomized experimental design with 2 treatments (feeding in trays or feeding to the throw) and 3 replicates was used. Prawn average weight, survival, productivity, and physical and chemical variables of the water were compared between treatments using "t" test of Student. Average weight, survival and productivity were, respectively, 7.2 +/- 0.3 g, 46.8 +/- 7.8% and 335 +/- 45 kg/ha in feeding tray treatment and 6.8 +/- 0.1 g, 85.8 +/- 5.2% and 586 +/- 42 kg/ha in feed to the throw treatment. Survival and productivity differed significantly (p<0.5), while that average weight didn't differ significantly. M. amazonicum needs to use further number of trays per area, possibly due to territorial and aggressive behavior.

Descriptive exploratory study, prospective with quantitative approach, performed on the Medical Regulation Central of SAMU/Natal, aiming to identify the level of professional satisfaction of the members of the nursing team working at SAMU/Natal; and verify the degree of importance attributed by the professionals to each of the components Professional Satisfaction: autonomy, interaction, professional status , work requirements, organizational rules and remuneration. The population was of 60 professionals, with data collected from january to february 2005. We used an instrument translated and validated by Lino (1999) to the portuguese language, the Professional Satisfaction Rate (PSR). The results demonstrate that there was a slight predominance of the female gender (54,9%); aged between 36 and 45 years old (60,8%); married (58,8%), 82,4% with children, 30,8% aged between 05 and 09. Regarding formation, we observed that 78,4% were nursing technicians and 21,6% nurses, formed for 11 to 15 years (17,5%). From the 11 nurses, 09 (81,8%) informed they have specialization, 29,4% of the team has been working for 11 to 15 years on the urgency area, 58.8% works for more than 02 years on SAMU, 72,6% of the team members have fixed work schedules. There was homogeneity on the work shifts: 41,2% on the day shift and 53% on the night shift. Regarding the reason to be working on SAMU, 64% chose to work in the service, and among these 76,3% predominantly perform direct care to the patients, 96,1% like and are satisfied to work in the service. Regarding the remuneration, 90,9% informed they receive 05 to 10 minimum wages; 70% of the technicians informed they receive -2 to 05 minumum wages, 50,1% informed they receive no additional benefit. The analysis of PSR through Cronbach s Alpha Coeficient resulted on the value of 0,94 and through Kendall s Tau Coeficient on 0,87, demonstrating to be a trustworthy instrument to measure the level of professional satisfaction of the SAMU nursing team, in our environment. As for the level of importance attributed to the components of professional satisfaction, we indentified that the nursing team considered the Autonomy component as the most important, followed by the component Remuneration, Interaction, Work Requirements, Work Requirements, Organizational Rules and Professional Status . Regarding the current level of professional satisfaction, we identified they were most satisfied with the Professional Status , Autonomy, Interaction, Remuneration, Work Requirements and Organizational Rules. The real professional satisfaction level, calculated through statistics, however, tells these professionals are more satisfied with Autonomy, Remuneration, Interaction, Work Requirements, professional Status and Organizational Rules. The PSR in our work was of 8,6, indicating the SAMU Natal nursing team has little satisfaction on their work environment

This work consisted in an experiment installed at Unesp, Campus of Jaboticabal, from January to May 2006 and the objective was to evaluate dry matter accumulated and nutrients by cauliflower, hybrid Verona, during the cycle. The experimental design was randomized blocks, in plots subdivided on the time, with three replications. The plants were sampled at 30, 45, 60, 75, 90, 105 and 120 days after sowing (DAS), and were evaluated: number of leaves, stem length, stem and curd diameter, leaf area, stem, leaves and curd dry matter and accumulate of nutrients. The cauliflower growth had four different phases. In the first one, from 0 to 30 DAS, was correspondent of the period from sowing to transplant. In the second phase, from 30 to 75 DAS, the dry matter accumulated in leaves and stem were small in comparison with the total. The third growth phase, from 75 to 97 DAS, was characterized with great dry matter accumulated, increase in the number of leaves and leaf area. This phase ended with visualization of the curd, and was the beginning to the fourth phase, from 97 to 120 DAS. In the culture estimated in 25,000 plants/ha and productivity of 25.2 t ha(-1) the accumulated quantities with of N, P, K, Ca, Mg and S were, corresponding to, 224.5; 54; 156; 136; 21.75; 63.5 kg ha(-1) and 714.8; 270; 236.7 and 33.3 g ha(-1), corresponding to Fe, Mn, Zn and Cu.

A acidez do solo no sistema plantio direto pode ser minimizada com aplicação superficial de calcário. Tal prática é favorecida pela permanência de restos vegetais na superfície do solo, pela liberação de compostos orgânicos hidrossolúveis, que variam de planta para planta. Por isso foi instalado um experimento em Latossolo Vermelho distrófico (V = 41 %) em Botucatu (SP), objetivando avaliar os efeitos da aplicação superficial de calcário dolomítico na concentração de cátions solúveis nos resíduos vegetais das culturas de milheto, feijão e aveia preta em dois anos agrícolas (2002/2003 e 2003/2004). No caso do feijoeiro, o delineamento experimental utilizado foi o de blocos casualizados em esquema de parcelas subdivididas, com quatro repetições. As parcelas foram representadas por cultivares de feijão (Carioca, IAC Carioca Eté, Pérola, IAPAR 81 e Campeão 2), enquanto as subparcelas foram formadas por doses de calcário dolomítico (sem aplicação, 1,8; 3,6 e 5,4 t ha-1). Para o milheto e aveia preta foram consideradas apenas as doses como fator. Foram avaliados os teores de Ca, Mg, K e Mn na parte aérea de todas as culturas, bem como a condutividade elétrica no extrato. Os resultados evidenciaram que os teores de Ca, K e Mg solúveis na parte aérea das culturas anuais avaliadas não foram alterados com a aplicação superficial de doses de calcário dolomítico. As culturas do milheto e feijão apresentaram maior teor de cátions solúveis na parte aérea, quando comparado ao da aveia preta.

This study had the purpose of identifying the health professional performance during the care of children victimized by violence. Its objectives were the evaluation of how health professionals diagnose violence on the hospitalized child during the care process; the identification, according to the experience of each health professional, of the types of violence on the hospitalized child, the child's aggressors and the most frequent1y injured area in the body and the analysis of conducts adopted by health professionals upon the recognition of a violence case on a hospitalized child. The study was of the descriptive-exploratory type, using a quantitative approach, performed on Hospital da Criança Santo Antônio (HCSA) in Boa Vista - RR. The population consisted of 235 health professionals, with data collected from June to August 2006. The results show a clear predominance of the female gender, (76,17%); aged 31 to 35 (26,81%); married (45,96%). As for professional formation, 63,9% were nursing auxiliaries and technicians,16,2% physicians, 14,8% nurses, 3,9% social assistants and 2,1% psychologists; 45,96% had completed middle-level education, 51,06% of which coming from private education establishments and 48,94% from public education institutions.; 97,66 % have specialization or improvement courses on their area; 32,77% among 05 to 09 years of work time; 32,06(10 worked on pediatric infirmaries; 75,74% state they have experience with children victimized by violence; 96,22% consider themselves capable of identifying the types of violence suffered by children; 29,00% consider physical violence the most common kind; 91,57% sought to identify the aggressors; 27,72% consider the mother to be the child's main aggressor, 26,36% the father, and 22,28% the stepfather; 26,55% consider the limbs and pelvic waist to be the body region most affected by violence; 26,91% take the attitude of reporting to the nurse and 20,13% to the social service; 70,79% state that the conducts were performed as a team; 26,25% of the professionals consider that the social assistants helped the most on deciding which conduct to adopt; 76,40% state there was no one opposed to the performing of these conducts; but 23,60% that stated there was no one opposed to the performing of these conducts, 77,08% reveal that the family members were against the conducts taken by the team. We conclude that, the hea1th professionals who were part of the study, apparently are not adequate prepared to diagnose and report the violence on child. The results were more drastic when we related the physicians and the nurses' answers, considering that they give directed assistance to these victims social assistants and psychologists are the ones best prepared to conduct cases of child mistreatment. However, we are conscious of our responsibility with professional education not only in upper grade institution but also on the middle-level. We believe also, that a continued education program can help to improve the professional knowledge and improve the quality of care

Este trabalho objetivou avaliar os efeitos da aplicação de calcário ao substrato de produção das mudas de maracujazeiro, acompanhando os benefícios no desenvolvimento, na produção de matéria seca e no estado nutricional das plantas. O delineamento experimental foi em blocos ao acaso, com cinco tratamentos e quatro repetições. As doses de calcário calcinado foram aplicadas objetivando elevar em meia; uma vez; uma vez e meia, e duas vezes a dose para elevar o V = 80%, correspondendo a 0,44; 0,88; 1,32; 1,76 g por vaso, respectivamente, além da testemunha sem aplicação. As mudas receberam doses de N, P, K, Zn e B de 300; 450; 150; 5,0 e 0,5 mg dm-3, respectivamente, sendo o N e o K parcelados em três vezes (30; 45 e 60 dias após a semeadura). O experimento foi conduzido em casa de vegetação da FCAV/Unesp, em Jaboticabal-SP, no período dezembro/2002 até abril/2003. A unidade experimental foi constituída por vasos com 2 dm³ de substrato de um Latossolo Vermelho distrófico. Após 80 dias da semeadura, avaliaram-se: o diâmetro do caule, a altura, o número de folhas, a área foliar e a matéria seca da parte aérea e das raízes, bem como os teores de macro e micronutrientes. As mudas de maracujazeiro responderam à aplicação de calcário. O maior desenvolvimento das plantas esteve associado à saturação por bases do solo de 56% e a concentrações de Ca e Mg no solo de 20 e 8 mmol c dm-3, e a teores de Ca e Mg na parte aérea de 12,8 e 4,0 g kg-1, respectivamente.

Sabe-se que os solos das regiões tropicais, devido ao intemperismo, apresentam baixas concentrações de micronutrientes, especialmente zinco. Desse modo, objetivou-se avaliar a aplicação de zinco ao substrato de produção de mudas de maracujazeiro, acompanhando seus efeitos no desenvolvimento, no estado nutricional e na produção de matéria seca das plantas. O delineamento experimental foi em blocos ao acaso, com cinco tratamentos e quatro repetições. As doses de zinco, na forma de sulfato de zinco, foram: 0; 2; 4; 6 e 8 mg de Zn dm-3 de solo. As mudas receberam doses de N, P, K e B de 300; 450; 150 e 0,5 mg dm-3, respectivamente, sendo o N e o K parcelados em três vezes (15; 30 e 45 dias após a semeadura). O experimento foi conduzido em condições de casa de vegetação, em vasos com 2 dm³ de substrato de um Latossolo Vermelho distrófico. Após 70 dias do plantio, avaliaram-se: o diâmetro do caule, a altura, a área foliar e a matéria seca da parte aérea e das raízes, bem como os teores de macro e micronutrientes. As mudas de maracujazeiro responderam positivamente à aplicação de zinco. O maior desenvolvimento das mudas esteve associado à dose de 5 mg de Zn dm-3.
