The present study aimed to analyze the floristic and structural descriptors of tree species natural regeneration in a forest sector with synchronized bamboo (Merostachys multiramea Hackel) die-off (CT) and an adjacent area with continuous canopy cover (ST) in an araucaria forest fragment in the municipality of Lages, Santa Catarina state. A total of 14, 5x5m, plots (six plots in CT sector and eight in ST sector) were allocated, where all tree species regenerative individual with circumference at breast height smaller than 15cm and height higher than 25cm was measured (diameter at soil level) and identified. The richest families were: Myrtaceae (nine), Solanaceae (six) and Aquifoliaceae (four). The Shannon Diversity Index in ST and CT sectors were respectively 2.73 and 2.31. The species with the highest importance values in CT sector were Solanum variabile, Piptocarpha angustifolia, Mimosa scabrella, Jacaranda puberula and Solanum pseudoquina. In ST sector, the species with highest importance values were Myrsine lorentziana, Casearia decandra, Cinnamodendron dinisii, Drimys brasiliensis and Ilex paraguariensis. The results showed that the synchronized bamboo die-off influenced the spatial variation in the floristic and structural descriptors of the tree species natural regeneration.

In road safety studies that involve accidents comparisons in distinct geographical spaces or in different periods of time in the same geographical space, the index which lists the number of traffic fatalities with the distance traveled by road transport vehicles is considered more appropriate than the rates related to the population or the fleet. In this paper, the results of an original research are presented, in which the values of the rate of traffic deaths per billion kilometers traveled (IMBQ) by the motor vehicle fleet in Brazil and in each state of the country were estimated. The evaluation was performed based on the official number of fatalities provided by the Ministry of Health and on the amount of fuel sold informed by the National Agency of Petroleum, Natural Gas and Biofuels. In 2009, Brazil presented an index of 52.84 fatalities per billion kilometers, which reveals an extremely alarming situation considering that this value is from 7 to 12 times higher than the one for more developed countries. An important correlation between the death index in the states and the Gross Domestic Product (GDP) per capita was observed; in general, the less economically developed is the state, it means, lowest GDP, higher is the IMBQ.

Purpose: to review literature, highlighting current aspects of maternal mortality.  Method: research initiated through electronic data base PubMed [http:// www.ncbi.nlm.nih.gov/pubmed], limited to the last 10 years. The selected cases which related to pre-defined aspects of interest to the study, such as vulnerable population, risk factors, causes, difficulties in obtaining data, preventive measures e new approaches to the problem, among them, ‘near misses’ and severe maternal morbidity.  Results: maternal death is directly related to the quality of life of the population, with relevant disparities among the different social economic areas. Although maternal mortality is the proper indicator to the female population health, its numbers are presented in unrealistic manners due to the difficulties in identifying the cases through death certificates. Preventive measures associated to early and adequate diagnose and treatment are benefic factors in decreasing those maternal deaths. Apart from these, identification and classification of ‘near misses’ and maternal morbidity are featured in the contemporary approach to the issue.  Final considerations: In spite of advanced technology and recognition of preventive measures, a large number of women die daily due to complications in the pregnancy and puerperal cycle. To decrease such tragedy political, social and economical commitment to Health is necessary, in order to promote the needed reforms in the assistance of such cycle.

The study aimed to determine the coefficient of the yellow passion fruit cultivation and irrigation set capable of increasing crop productivity and quality of production in the environmental conditions of the semi-arid region of Piauí. The experiment was conducted in the Pilot Project for Fruit Crops Irrigated area in Santa Rosa, PI. We used a randomized block design with six treatments and four replications. Treatments (irrigation) were defined according to percentages of reference evapotranspiration (ETo): T1 25%, T2: 50%, T3: 75%, T4: 100%; T5: T6 and 125%: 150%. For monitoring water in the soil profile was used tensiometers. To determine the crop coefficient (Kc) used the water balance in the soil treatment based on 100% replacement of water. Morphological and physiological characteristics of yellow passion fruit were evaluated. The maximum yield of 27.052 kg ha-1 yr-1 was obtained by applying a water depth of 763.80 mm. The values of average fruit weight ranged from 0.207 kg (T6) and 0.159 kg (T1). The average kc obtained for the vegetative stage was 0.57 to 0.94 and flowering stage to fruiting phase 1.04. The water depth of greater efficiency comprise in the range of 75% and 100% ETo.
