Influence of seismic activity on the atmospheric electric field in Lisbon (Portugal) from 1955 to 1991

In the present study, we considered the influence of seismic activity on the atmospheric electric field recorded at Portela meteorological station (Lisbon, Portugal) for the period from 1955 to 1991. To this end, an exploratory method was developed, which involved the selection of events for which the distance from the atmospheric electrical field sensor to the earthquake epicenter is smaller than the preparation radius of the event. This enabled the correlation of the atmospheric electric field variations with a quantity S, defined basically as the ratio of the earthquake preparation radius to the distance between the sensor and the event epicenter. The first results show promising perspectives, but clearly a more profound study is required, in which a careful analysis of the weather conditions and other variables, like atmospheric radon levels, must be considered

Simulação Em 3d Da Redução Da Fossa Posterior No Chiari Do Tipo I

We proposed a 3D model to evaluate the role of platybasia and clivus length in the development of Chiari I (CI). Using a computer aided design software, two DICOM files of a normal CT scan and MR were used to simulate different clivus lengths (CL) and also different basal angles (BA). The final posterior fossa volume (PFV) was obtained for each variation and the percentage of the volumetric change was acquired with the same method. The initial normal values of CL and BA were 35.65 mm and 112.66° respectively, with a total PFV of 209 ml. Ranging the CL from 34.65 to 29.65-24.65-19.65, there was a PFV decrease of 0.47%-1.12%-1.69%, respectively. Ranging the BA from 122.66° to 127.66°-142.66°, the PFV decreased 0.69%-3.23%, respectively. Our model highlights the importance of the basal angle and clivus length to the development of CI. © 2016, Associacao Arquivos de Neuro-Psiquiatria. All rights reserved.74540540

Electrolytic Treatment And Biosurfactants Applied To The Conservation Of Eugenia Uniflora Fruit

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Microorganisms are the primary responsible for food poisoning and food spoilage. The purpose of this study was to evaluate different fruit washing methods with tap water, electrolyzed water and rhamnolipids solution produced by Pseudomonas aeruginosa LBI, in order to inhibit microbial growth. The tested organism was Eugenia uniflora. The fruits were washed and periodically inoculated into culture media to evaluate and count the colonies on the fruit surface. It was also observed the deterioration level of the fruits after each treatment. The results showed that treatment with rhamnolipids were the most efficient, inhibiting the growth of fungi and bacteria. The electrolyzed water proved to be very efficient in bacterial inhibition at the initial time, but in the final time it did not present any inhibitory effect. The electrolyzed water was also not effective in eliminating fungus. Washing with tap water was the less efficient treatment of all. The only treatment that showed an increased durability has been with rhamnolipids, increasing shelf life by up to two days. Thus rhamnolipids are the most recommended method for fruits sanitation. © 2016, Sociedade Brasileira de Ciencia e Tecnologia de Alimentos, SBCTA.

Evaluation of the cardiovascular effects of vasicine, an alkaloid isolated from the leaves of Sida cordifolia L. (Malvaceae)

The cardiovascular effects of vasicine, an alkaloid isolated from the leaves of Sida cordifolia L., were evaluated in this work. In non-anaesthetized rats (n=6), vasicine (1, 2.5, 5 and 10 mg/kg; i.v., randomly) induced hypotension associated with an intense bradycardia. Both responses were completely abolished after atropine (2mg/Kg; i.v.) and attenuated after hexamethonium (20 mg/Kg; i.v.). In isolated rat mesenteric artery rings, vasicine (0.03, 0.1, 0.3, 1, 3, 10, 30, 100 and 300 μg/mL, cumulatively) induced concentration-dependent relaxation of phenylephrine-induced tone (IC50= 3.8±0.9 μg/mL; n = 6). In conclusion, the results show that vasicine produce hypotension and bradycardia which appears to be due to the stimulation of cardiac muscarinic receptors (directly and/or indirectly), and by a decrease of the peripheral resistances

Suicide Pact

Objective: To determine the time of diagnosis of typical orofacial clefts in different Brazilian regions and its influence on age at surgical correction. Method: This was a prospective, descriptive, cross-sectional study conducted in medical centers in the Southeast, South, and Northeast of Brazil. Trained speech therapists and geneticists interviewed the parents of affected children using a previously validated questionnaire. Epi-Info and SPSS were used for data analysis. Significance level was set at 5% (p ≤ 0.05). Results: The sample consisted of 215 interviews conducted in the following regions: 21.9% (47) in the Southeast, 51.1% (110) in the South, and 27% (58) in the Northeast. Monthly family income was higher in the Southeast (p ≤ 0.05). Cleft lip and palate were found in 61.4% (132) of cases, cleft palate in 20.9% (45), and cleft lip in 17.7% (38). Diagnosis occurred in the maternity ward in 75.3% (162) of cases, during the prenatal period in 14% (30), and after hospital discharge in 10.2% (22). The Southeast had a higher frequency of prenatal diagnosis (27.7%), possibly related to greater purchasing power in this region and greater availability of prenatal investigation. Of all cases diagnosed in the maternity ward, 74.4% occurred in the Northeast. However, no significant difference was found when comparing time of diagnosis, region, and age at first surgery. Conclusion: Considering that diagnosis is more common in the maternity ward, local health care teams should be trained in order to effectively improve the initial care of these patients. Although time of diagnosis did not affect age at surgery, it favors the planning of neonatal care and treatment of affected infants.

Uma aplicação da teoria da decisão ao estudo da localização industrial

The purpose of this work was to study plant location regarding transportation entailed to location trees; it was analyzed the case where there is uncertainty in one of the determinant variables of that decision, or the rate referring to the transportation of raw materials. The development of the various parts of the work has been done based on a numerical example. The • classical method used in solving a problem without uncertainty is the Cutting Method, which was first presented here. The solution of the problem with uncertainty is done through the use of decision trees, which allows also the study of the information value about raw materials transportation rate, where we initially only know the probability density function. The example with uncertainty was solved initially for the case in which the decision maker is indiferent about the risk, following the case in which he is risk adverse. Involvements about the decision of the location, as a function of the behavior of the decision maker, was pointed out in the work

The Problem of Large Leptonic Mixing

Unlike in the quark sector where simple $S_3$ permutation symmetries can generate the general features of quark masses and mixings, we find it impossible (under conditions of hierarchy for the charged leptons and without considering the see-saw mechanism or a more elaborate extension of the SM) to guarantee large leptonic mixing angles with any general symmetry or transformation of only known particles. If such symmetries exist, they must be realized in more extended scenarios.Comment: RevTeX, 4 pages, no figure

Early sexual intercourse: Prospective associations with adolescents physical activity and screen time

Objectives: To assess the prospective associations of physical activity behaviors and screen time with early sexual intercourse initiation (i.e., before 15 years) in a large sample of adolescents. Methods: We used two waves of data from the Rotterdam Youth Monitor, a longitudinal study conducted in the Netherlands. The analysis sample consisted of 2,141 adolescents aged 12 to 14 years (mean age at baseline = 12.2 years, SD = 0.43). Physical activity (e.g., sports outside school), screen time (e.g., computer use), and early sexual intercourse initiation were assessed by means of self-report questionnaires. Logistic regression models were tested to assess the associations of physical activity behaviors and screen time (separately and simultaneously) with early sexual intercourse initiation, controlling for confounders (i.e., socio-demographics and substance use). Interaction effects with gender were tested to assess whether these associations differed significantly between boys and girls. Results: The only physical activity behavior that was a significant predictor of early sexual intercourse initiation was sports club membership. Adolescent boys and girls who were members of a sports club) were more likely to have had early sex (OR = 2.17; 95% CI = 1.33, 3.56. Significant gender interaction effects indicated that boys who watched TV ≥2 hours/ day (OR = 2.00; 95% CI = 1.08, 3.68) and girls who used the computer ≥2 hours/day (OR = 3.92; 95% CI = 1.76, 8.69) were also significantly more likely to have engaged in early sex. Conclusion: These findings have implications for professionals in general pediatric healthcare, sexual health educators, policy makers, and parents, who should be aware of these possible prospective links between sports club membership, TV watching (for boys), and computer use (for girls), and early sexual intercourse initiation. However, continued research on determinants of adolescents' early sexual initiation is needed to further contribute to the strategies for improving adolescents' healthy sexual development and behaviors

Parâmetros De Qualidade Físico-químicos E Avaliação Da Atividade Antioxidante De Folhas De Plectranthus Barbatus Andr. (lamiaceae) Submetidas A Diferentes Processos De Secagem

This paper describes the physicochemical composition, the evaluation of the antioxidant activity by free DPPH radicals using the scavenging method, the determination of flavonoids and total phenolic compounds of ethanol, acetone and aqueous extracts of the medicinal plant Plectranthus barbatus Andr. (Lamiaceae), dehydrated in solar dryer and circulation oven at 60 °C. Water activity rates for two drying methods were below the minimum necessary for growth and toxin production of important food pathogens. Physicochemical results showed that both processes were effective in the dehydration of P. barbatus. The results demonstrated that the acetone (over) and ethanol (over and solar dryer) extracts showed the highest content of total phenols. The ethanol extract (over) showed the highest amount of flavonoids and better antioxidant activity (75.71 ± 10.57 µg L-1). © 2016, Instituto de Biociencias. All rights reserved.181485
