Plants of spontaneous vegetation of the Brazilian Caatinga bioma have been used as green manure in vegetable production systems in Northeastern Brazil with the aim of increasing the productivity of vegetables and improving the exploitation of the environment. The present work was carried out to evaluate the effect of three spontaneous species of the Brazilian Caatinga as green manure in different amounts of biomass in the chemical attributes of soil-plant and in the productivity of beet. The experimental design was of randomized complete blocks with three replications, the treatments being composed of three spontaneous species of the Brazilian Caatinga: hairy woodrose (Merremia aegyptia); oneleaf senna (Senna uniflora) and roostertree (Calotropis procera) used in five amounts of dry biomass (5.4, 8.8, 12.2, 15.6 and 21.0 t/ha in dry basis) incorporated into the soil. The characteristics evaluated in the soil were the contents of organic matter, aluminum, macronutrients, pH and number of colony-forming units (CFU) in the soil of bacteria, fungi and actinomycetes after the harvest. From the plants we evaluated the macronutrient contents in the diagnostic leaf, besides the total and marketable productivity of roots, root dry mass and classified productivity of roots. In general, it can be concluded that the green manure using spontaneous species of the Caatinga biome (hairy woodrose, oneleaf senna and roostertree), provided improvement in the soil chemical properties and beet plants. The green manures obtained from the hairy woodrose and roostertree species were those that provided the best productive performance of beet, with average values of total and marketable productivity of 17.57 and 15.39 t/ha, and 18.74 and 16.33 t/ha, respectively. The addition to soil of 21.0 t/ ha of green manure biomass provided the greatest total (21.94 t/ha) and marketable yield (20.58 t/ha) of beet. © 2016, Sociedade de Olericultura do Brasil.

The article's objective is to describe which factors affecting to the success and/or the mortality of micro and small companies in the State of Santa Catarina are. It was elaborated, therefore, a field study with a sample of companies registered on Junta Comercial do Estado de SC from 2000 to 2004. The data were analyzed in quality and quantity method under two perspectives: i) Relevant factors on enterprise's history (real), which highest averages grades were given to the product/market knowledge, business focus, identification of opportunities, organization and product' suitability; and ii) factors that the entrepeneur believes to be the most important for the success (ideal), which highest averages grades were given to the organization, the relationship among the partners, the knowledge about the market, the business focus and the identification of oportunities.

The purpose of the present study was to analyze gas exchanges in leaves and the parameters of productivity of beans (Phaseolus vulgaris, L.) submitted to two water deficiency periods during which three water regimes were employed: W1 (1,0 ETo during the entire plant cycle); W2 (1,0 ETo up to the flowering period and irrigation interruption from the 37 to the 51st day following sowing, and W3 (in addition to the reproductive phase, water deficit was also applied during the vegetative stage). Photosynthesis was one of the main physiological factors affected by water deficit. This was not only caused by the stomata closure, but also by carboxilation reduction due to metabolic damage. This effect was, however, offset 24 h after rehydration. During flowering, the water deficit caused crop productivity to drop significantly, reducing the number of pods and the number of seeds per pod, independently of the water deficit during the vegetative stage. The weight of 100 seeds however, was the same regardless of treatment. These results suggest that the water deficit caused the reduction of photo-assimilates, which affected grain productivity. Nevertheless, once properly formed, seeds developed totally; a strategy of the plant to produce less seeds under stress, but viable to perpetuate the species. Source

This paper, as Part II of a research carried out in Sergipe state, aims to determine evapotranspiration and crop coefficient of dwarf-green coconut (Cocos nucifera L.) based on lysimeter measurements and Bowen ratio-energy balance method. The reference evapotranspiration was obtained by the Penman-Monteith approach on daily-scale during the experimental period. The data acquisition system was used to obtain all data from the sensors necessary to determine the energy balance components. The water requirements of coconut palm during the phenological growth stage is 1263.30 mm, with daily average of 3.90 mm d-1. The crop coefficient during this phenological growth stage varies between 0.50 and 1.80, with daily mean of 0.96. Source

Objective: To investigate the characteristics of the victims of suicide attempts treated in pre-hospital services and the time intervals consumed in this phase of care. Methods: Cross- -sectional study, which used data from pre-hospital care to victims of suicide attempts occurred in the town of Arapiraca, in 2011. For data analysis, Fisher's exact test, Student's t test and multiple logistic regression were performed. Results: A total of 80 victims of suicide attempts were treated by pre-hospital care service. Women over the age of men were the most attempted suicide victims (n = 44, 55%) and drug intoxication was the most used method (n = 44, 55%). Suicide attempts occurred more frequently in autumn (n = 29, 36.25%), on Sunday (n = 18, 22.5%), mainly in the afternoon (n = 33, 41.25%). The time spent in the pre- -hospital care varied between 34.4 and 40.5 minutes. The variables that were associated with suicide attempts by sex were: age (p = 0.03) and the transportation time (p = 0.01). Conclusion: It was found that there were differences between the sexes of the victims of suicide attempts treated by pre-hospital attendance. Women were older than men and the transportation time was higher in male victims, suggesting greater severity in suicide attempts committed by this particular group. Source
