Calla lily (Zantedeschia aethiopica) is appreciated as cut flower and for the composition of gardens. However, many pathogens affect this species. By the traditional method of propagation, some units of new seedlings can only be produced annually. Tissue culture allows fast large-scale clonal propagation and provides healthy uniform plants. During the in vitro process, type and concentration of growth regulator could affect the growth of seedlings. Thus, the aim of this work was to determine sucrose and GA(3) concentrations to increase the efficiency of the in vitro multiplication of calla lily. After 60 days, the length of the above ground part and the roots, the number of sprouts, roots and leaves, above ground part and root fresh weight of seedlings were evaluated. The experimental design was entirely randomized with four replications. It was necessary the addition of 60.5 g L-1 sucrose associated to 5 mg L-1 GA(3) to obtain hight sprouts number. For higher length of the above ground part the addition of 45.3 g L-1 sucrose and 10 mg L-1 GA(3) was enough. Better results in the root length and number of roots were observed only in the sucrose presence, in concentrations in the range of 51.13 - 56.5 g L-1.

Purpose: Cup feeding is an alternative technique of infant feeding when the infant is not being breastfed. Healthcare providers should have experience with the cup feeding technique in order to feed safely an infant. Objectives: The aim of this study is to identify the practices and the feeding cup techniques currently being used by healthcare NICU professionals, and to explore the opinions and beliefs of health professionals regarding to feeding cup. Methods: Twelve NICU nursing assistant were interviewed. Results: Most of the professionals interviewed were able to properly execute the feeding cup technique. The main problem observed was the improper positioning of the cup while using the technique. Most of them were ‘pouring’ the milk into the infant’s mouth. Thus, the participants interviewed expressed doubts about the technique and denied having been trained for this procedure in routine work at NICU. Nevertheless, all the participants were interested to learn more about the technique. Conclusion: In general,, all the professionals interviewed were able to properly execute the feeding cup technique. The questions and concerns presented by the professionals reassure the need for research and educational activities in order to educate health professionals about the correct use of feeding cup technique to assure a safe alternative feeding for infants.

This study aims to evaluate the weight gain of premature newborns fed with breast milk from their mothers' from those that are fed with breast milk from the milk bank. The research is the quantitative, descriptive and observational kind. It was conducted in the Neonatal Intensive Care Unit and Housing from the Maternity Hospital Escola Januário Cicco (MEJC), that is a reference for high risk pregnancy and birth in Rio Grande do Norte. The premature newborns included were following these parameters: gestational age from 26 to 37 weeks, initially hospitalized at UTIN, with oral diet, by means by gavage, cup and/or suction. Studies with premature newborns with a zero diet longer than seven days or complications that interfered in the evaluation of weight gain were excluded from this study. The sample was selected for convenience and had data of all newborns hospitalized at UTIN from the May to June of 2014 time period, followed to their discharge, ended by August of 2014 and had the inclusion parameters of the study. From the period of the data collection, 60 premature newborns entered the maternity and 39 of those were the sample of research. The project was approved by the Research Ethics Committee from UFRN, under CAAE nº 0699.0.000.294-11. The data was analyzed by means of descriptive and deduced statistics. The results indicated that the involved in the study, were born from mother with average age of 25,36 years, with less than nine years education 21 (53,8%), had the family income less than a minimum wage 24 (61,5%). Among the newborn, the female gender predominated 20 (51,3%), had cesarean delivery 25 (64,1%), had moderate prematurity 29 (74,5%), more of 1.500g 22 (556,4%). The birth weight average was 1.608,49g. The total of diets were 9.994, and an average of 256 for each newborn, in a 32,12 days of hospitalization time period. Most of the diet supplies were from the breast milk bank (50,34%), however 56,4% of the newborns had most of the diet from their mothers' milked breast milk. It was detected that 38,5% of the newborns had, in some given moment, artificial milk. The daily weight gain average of all newborns was 2,59g, but 35% of them had an average above 10g per day. From the newborn's group (n=25) that had medium weight gain, only 9 of them (36,0%) received mainly their own mothers' milked breast milk. It's been conclusive that most of the premature newborns gained weight predominantly from diets from the breast milk of the Milk Bank, showing the need of a bigger incentive to exclusive breast feeding.

Este trabalho procurou analisar o sistema produtivo da atividade leiteira em Minas Gerais, identificando a capacidade dos produtores em permanecer no negócio, a longo prazo, através da estimação da função custo translogarítmica. O estudo demonstrou que os produtores analisados ainda praticam altos custos por unidade produzida, sugerindo baixa eficiência dos estabelecimentos e falhas na administração do empreendimento. Os resultados econométricos revelam a possibilidade de ganhos de escala, no que se refere à alocação e melhor aproveitamento dos recursos, ou seja, as propriedades apresentam economias de escala. No entanto, retornos crescentes de escala não são compatíveis com a existência de mercados competitivos, sinalizando que os produtores enfrentam restrições geradas pelas imperfeições de mercado. O conhecimento dessas imperfeições é essencial à formulação de políticas econômicas e de organizações privadas que visem ao desenvolvimento econômico deste mercado, que atualmente é o sexto maior do mundo. Além disso, os resultados das elasticidades mostram que o produtor é mais sensível às variações de preços na mão-de-obra do que às variações nos demais fatores, reduzindo em maior proporção o uso do trabalho na produção, à medida que seu preço aumenta. Isto evidencia a principal característica regional da produção leiteira no país, que é o uso intensivo do fator trabalho. Também foi identificado que o os medicamentos, alimentos e energia, denominados no estudo de fator dispêndio, são os mais difíceis é o mais difícil de serem substituídos na produção, devido às particularidades no uso dos componentes deste insumo. Por fim, os valores positivos encontrados para as elasticidades parciais de substituição de Allen confirmam a substitutibilidade entre os fatores.
