Abstract: Objetivou-se com esse trabalho avaliar o efeito da salinidade da água de irriga o nas características agron micas do amendoinzeiro (Arachis hypogaea L.) cultivado em solo sem e com biofertilizantes. O experimento foi conduzido em estufa telada na Esta o Agrometereológica, Campus do Pici, Fortaleza, CE. A semeadura foi feita em vasos utilizando-se, como substrato, um Argissolo Vermelho-Amarelo, com uma planta por vaso. O experimento obedeceu a um delineamento inteiramente casualizado, em esquema fatorial 4 x 3, com cinco repeti es. Os fatores referem-se aos valores de condutividadeelétrica da água de irriga o: 1,5; 3,0; 4,5 e 6,0 dS m-1 e sem e com biofertilizantes (sem biofertilizante -B0; com biofertilizanteanaeróbico-B1; e com biofertilizante aeróbico - B2). Foram avaliadas as seguintes variáveis: pH, condutividade elétrica do solo, crescimento inicial em número de folhas, altura de plantas, diametro do colmo, área foliar e matéria seca da parte aérea. O biofertilizante bovino diminuiu os efeitos negativos das concentra es crescentes de sais na água de irriga o nas variáveis estudadas. O nível salino do solo foi maior na presen a do biofertilizante anaeróbico. O biofertilizante anaeróbico foi mais eficiente que o aeróbico na redu o dos efeitos depressivos dos sais das águas de irriga o às plantas.This study evaluated the effects of irrigation water salinity on agronomics characteristics of peanut (Arachis hypogaea L.), cultivated without and with biofertilizers. The experiment was conducted in a greenhouse in the Esta o Agrometereológica, Campus do Pici, Fortaleza, CE. The seeds were sown in pots using, as substrate, a Red-Yellow Argisol, with one plant per pot. The experiment followed a completely randomized design set as a 4 x 3 factorial, referring to four irrigation water electrical conductivity values: 1.5, 3.0, 4.5 and 6.0 dS m-1 in three soil configurations: B0(without biofertilizer), B1 (with anaerobic biofertilizer) and B2 (with aerobic biofertilizer), with five repetitions. The following variables were evaluated: pH, soil electrical conductivity, initial growth in number of leaves, plant height, stem diameter, leaf area and dry shoot mass. The bovine biofertilizer reduced the negative effects of increasing saline concentration in irrigation water in the variables evaluated.The soil salinity level was higher in the presence of anaerobic biofertilizer. The anaerobic biofertilizer was more efficient thanaerobic biofertilizer in reducing the depressive effects (to plants) of irrigation water salts.

Abstract: the purpose of this study was to evaluate the effect of irrigation with water of high and low salinity on the initial growth of corn plants grown in soil fertilized with bovine bio-fertilizer. the experiment was conducted in a greenhouse of the department of soil science - ufc. the seeds were planted in vessels with a 12 kg capacity, containing alfissol as substrate and one plant per pot. the experiment followed a completely randomized design, in a 5x2 factorial scheme, with four replications, referring to five concentrations of bio-fertilizer: c1 = 50% biofertilizer + 50% water (1:1), c2 = 33.33% biofertilizer + 66.67 + water (1:2), c3 = 25% biofertilizer + 75% water (1:3), c4 = 20% biofertilizer + 80% water (1:4) and c5 = 11.12% biofertilizer + 88, 88% water (1:5) and two salinity levels of irrigation water for s1 = 0.8 ds m-1 (low salinity) and s2 = 3.4 ds m-1 (high salinity). we analyzed the early growth of plants as compared to the readings of electrical conductivity of water saturated soil extracts (ecse) by using the collected data on plant height, stem diameter, leaf area, shoot dry matter, root dry matter and total dry matter. irrigation with low salinity water was found more efficient in promoting the initial growth of plants under increasing concentrations of biofertilizer, except for root dry matter. under the same concentrations of biofertilizer, plus irrigation with saline water, soil salinity increased, but did so with less intensity in soil irrigated with low salinity water.

Abstract: Dentre as oleaginosas utilizadas no Programa Brasileiro de Biodiesel (ProBiodiesel), a mamoneira destaca-se devido a alta adaptabilidade à condi es adversas do clima e à multiplicidade de aplica es industriais do seu óleo. O objetivo do presente trabalho foi avaliar os efeitos de doses crescentes de nitrogênio, aplicadas via fertirriga o, na cultura da mamoneira (Ricinus communis L.) cultivar IAC-Guarani. O experimento foi implantado em uma área experimental da Universidade Federal do Ceará, no município de Fortaleza (03o44’S, 38o33’W, 19,5 m). A semeadura foi feita em covas, a uma profundidade de 3 a 5cm, no espa amento de 1,0 x 1,0 m. A aduba o de funda o foi composta de micronutrientes (15 g de FTE BR-12) e de fósforo, na forma de MAP (1.740g). Os macronutrientes nitrogênio e potássio foram aplicados via fertirriga o, semanalmente. Durante o ciclo da cultura, as plantas foram irrigadas diariamente por sistema de irriga o de gotejamento, onde as laminas foram quantificadas a partir de 75% da evapora o medida no tanque classe “A” (ECA). O delineamento experimental foi em blocos ao acaso com cinco tratamentos: 0, 50, 100, 150, e 200% do nitrogênio recomendado na análise de solo e quatro repeti es. A aplica o das diferentes doses de nitrogênio via fertirriga o, influenciaram os fatores produtivos peso de 100 sementes dos racemos de 2a e 3a ordens e as produtividades do racemo de 3a ordem e produtividade total da mamoneira. A dose de nitrogênio estimada de 131% da recomendada pela análise de solo foi a que proporcionou a maior produtividade total.

Abstract: this study aimed to assess quality of obstetric care for preterm labor patients, using referents, indicators, and standards derived from scientific evidence, focusing on antenatal corticotherapy. available metanalyses and randomized controlled trials were examined to establish referents, defining indicators and estimating process and outcome standards for the present study. data from hospital discharge summaries of seven public maternity hospitals in rio de janeiro were analyzed. the standard of process used was 100%. it was not possible to estimate outcome standards, since the necessary adjustment for gestational age was not feasible. utilization of antenatal corticotherapy in the present study was very low, about 4% and 2%, considering patients up to 33 weeks and 6 days and 36 weeks and 6 days, respectively. failure to use antenatal corticotherapy when formally indicated deserves attention by health planners and managers, considering: a) the ease in incorporating such a technology, in contrast to the adequate incorporation of special/intensive neonatal care; b) benefits and costs associated with this technology compared to those of delivering neonatal care to premature babies.

Abstract: several studies show that portions of intramyocardial coronary arteries are spared of arteriosclerosis, involving morphological, embryological, biochemical and pathophysiological aspects. endothelial function is significantly affected in the segment of transition, as estimated by the vasoactive response to ach. these findings suggest that myocardial bridge can provide protection against arteriosclerosis by counteracting the negative effects of endothelial dysfunction. the intramyocardial portion's protection phenomenon deserves further scientific research on all research fronts. improved morphological, biomechanical and especially physiological and embryological knowledge may be the key to a future window of opportunity for chronic arterial disease therapy and prevention. in addition, this review discusses possible therapeutic approaches for symptomatic coronary ischemia caused by myocardial bridges
