title: Police use of deadly force in the State of São Paulo

description: Abstract The police constitute the main mechanism found by the modern state to guarantee the maintenance of law and order, with the prerogative of regulation of social relations through physical force as a legitimate and constitutive act. While the police represent the authority to intervene when necessary, they may violate citizens’ rights when making abusive use of force, especially lethal force. This article presents a descriptive analysis of reports on cases where police used lethal force in the State of São Paulo. The results indicate that, even in the face of a significant reduction in homicides, the use of deadly force by the police increased substantially during the 2000s, disproportionately affecting black people, particularly adolescents and young adults. The research concludes that the police have exceeded the use of deadly force and suggest strengthening the police’s internal control to address the problem.

title: Land-use influence on the soil hydrology: An approach in upper Grande River basin, Southeast Brazil

description: ABSTRACT Brazil is a large country that depends on the hydroelectricity generation hydropower dams. The Upper Grande River Basin (UGRB) is one of the most important Brazilian hydrological regions in terms of water availability and electric energy production. Therefore, studies of water availability are indispensable for a better and more successful decision making in water resources management in the region. This study objective to approach the land-use influence on the soil hydrology in the Upper Grande River Basin, a strategic headwater basin of southeastern Brazil. This study uses hydrological indicators (baseflow/runoff (BF/R) and overland flow/runoff (OF/R)) extracted from eight watersheds, varying the size and localization in the region, to support the results found. Soil saturated hydraulic conductivity (Ko) was determined in situ using a constant flow permeameter, totaling 224 sampled points. Five machine learning algorithms were compared in their performance to predict Ko (Random Forest, Support Vector Machine, Gradient Boosting, Linear Regression, Regularization) using terrain attributes as covariates. The tested methods for predicting Ko resulted in a relatively low coefficient of determination (R2) due to the high spatial variability of this soil hydrologic attribute. The hydrological indicator BF/R was sensitive to land-use changes in the watersheds. The greatest Ko values were associated with native forest and the least values area associated with pasture and rupestrian field.

title: Proposta de processo para o desenvolvimento de projetos de empreendimentos públicos

description: Abstract The design and budget development process of public projects is done in a fragmented way by the stakeholders. This situation contributes to several inadequacies in construction projects, related mainly to costs and deadlines. The aim of this paper is to propose improvements to the process, based on Target Value Design (TVD). The investigation was done through qualitative research, and the research strategy used was a multiple case study. It involved four public institutions, comprising project the development, budget and inspection sectors. The study included the following participants: clients, managers, designers (architect and engineer), budgeters, and works inspectors. Seventeen participants were interviewed during the study. This paper presents a design development process model for public projects (DDP).

title: Analytical study of the curve of static bending test for wood specimens

description: Abstract The NBR 7190:1997 "Design of Timber Structures" provides the procedure for several mechanical tests, and among them, the Static bending test for Modulus of Elasticity (Em) and Conventional Value of Strength (fm) determinations. It is common to characterize wood batches with a small number of specimens, what makes it difficult to perform an estimative test for rupture determination, and afterwards, to carry out the loading cycle for Em estimation. In these cases, instead of Force parameters, Deflection parameters are used for the loading cycle. This paper aims to identify a pattern between Force and Deflection parameters by investigating the Force vs. Deflection curve of the static bending test of wood specimens. According to results, there is a well pronounced pattern between Force and Deflection parameters in the linear part of the Force vs. Deflection curve, and based on this, we proposed a linear regression model between logarithm values of the force percentage (in relation to the rupture) and the denominator of the span value (as a Deflection parameter), resulting R2 equal to 97.41%. This result makes the conduction of the static bending test easier in specialized laboratories for testing of wood.

title: Symbolic consumption and representation of self: a study of interactions in a virtual community of Ubuntu-Br users

description: Abstract This study aims to explain how the symbolic consumption of the Ubuntu operating system is used for the representation of self in interactions in the Ubuntu virtual community from Brazil. We adopted the Goffmanian concept of self, the netnography of communication as the research method, and case study as a research strategy. The paralinguistic, the extralinguistic, and the definition of “I” are aspects used in virtual interactions. They have the linguistic function of corroborating and praising the statements of migration of Windows users to Ubuntu, emphasizing the distinctive features of the concept of Ubuntu, highlighting its expression of shared feelings of love and freedom, as ways of projecting the self of humanity to each other. In the case of the operating system, this characteristic is represented through the provision of support among users at the forum of the virtual community.

title: PRIMARY SPHINCTEROPLASTY COMPARING TWO DIFFERENT STITCHES IN ANAL FISTULA TREATMENT: EXPERIMENTAL STUDY IN RATS

description: ABSTRACT Background: Anal fistula is by definition the communication between the rectum or anal canal with the perineal region, which may be epithelialized and has cryptoglandular origin in 90% of cases. There are a large number of techniques for successfully treating trans-sphincteric fistulas of 20-50%, including primary sphincteroplasty, but it is not clear whether the material used would influence the outcome. Aim: To analyze the efficacy of polydioxanone and polypropylene wire in primary post-fistulotomy sphincteroplasty in the treatment of trans-sphincteric fistulas in rats. Methods: Thirty Wistar rats had transfixation of the anal sphincter with steel wire, which remained for 30 days for the development of the anal fistula. After this period, it was removed and four groups were formed: A (control) without treatment; B (fistulotomy) submitted to such procedure and curettage only; C (polidioxanone) in which sphincteroplasty was performed after fistulotomy with polydioxanone wire; D (polypropylene) submitted to the same treatment as group C, but with polypropylene wire. After 30 days, euthanasia and removal of the specimens were performed for qualitative histopathological analysis, measurement of the area between the muscular cables edges and evaluation of the degree of local fibrosis. Results: There was persistence of the anal fistula in all animals of group A. There were no significant differences between groups B, C and D regarding the distance of the muscular cables (p=0.078) and the degree of fibrosis caused by the different treatments (p=0.373). Conclusions: There was no difference between polydioxanone and polypropylene wires in post-fistulotomy primary sphincteroplasty, and this technique was not superior to simple fistulotomy in relation to the distance of the muscular cables nor did it present differences in relation to the degree of local fibrosis.

title: EFFICACY OF CURCUMA LONGA IN THE TREATMENT OF DIVERSION COLITIS IN RATS

description: ABSTRACT Background: Diversion colitis is still very common in our country, since the stoma creation is a common practice especially in situations of trauma. needing treatment for this condition. Aim: To evaluate the therapeutic effect of rectal infusion of Curcuma longa (turmeric) in the excluded intestinal segment of rats. Method: Eighteen Wistar rats were used and submitted to colostomy: control group (n=8) under rectal saline infusion and group CL, receiving intra-rectal infusion of Curcuma longa extract (n=10). After 21 days of treatment they were submitted to euthanasia; the intestinal segment excluded from intestinal transit was resected and sent to histopathological evaluation, classifying the degree of inflammation and of vascular congestion. Results: The average of inflammation was 2.7 in the control group vs. 2.6 in the CL group (p=0.3125), while the mean vascular congestion was 2.3 and 2.1, respectively, in the control and CL groups (p=0.1642). Conclusion: Intra-rectal infusion of Curcuma longa extract was not able to minimize the inflammatory process or vascular congestion in the diversion colitis of rats subjected to colostomy.

title: EFFECT OF PROBIOTIC ORAL ADMINISTRATION ON SKIN WOUND HEALING IN RATS

description: ABSTRACT Background: Manipulating intestinal microbiota with probiotics might stimulate skin response. Understanding all stages of the healing process, as well as the gut-skin-healing response can improve the skin healing process. Aim: To evaluate the effect of perioperative oral administration of probiotics on the healing of skin wounds in rats. Methods: Seventy-two Wistar male adult rats were weighed and divided into two groups with 36 each, one control group (supplemented with oral maltodextrin 250 mg/day) and one probiotic group (supplemented with Lactobacillus paracasei LPC-37, Bifidobacterium lactis HN0019, Lactobacillus rhamnosus HN001, Lactobacillus acidophilus NCFM® at a dose of 250 mg/day), both given orally daily for 15 days. The two groups were subsequently divided into three subgroups according to the moment of euthanasia: in the 3rd, 7th and 10th postoperative days. Results: There were no significant changes in weight in both groups. Wound contraction was faster in probiotic group when compared to the controls, resulting in smaller wound area in the 7th postoperative day. As for histological aspects, the overall H&E score was lower in the probiotic group. The probiotic group showed increased fibrosis from 3rd to the 7th postoperative day. The type I collagen production was higher in the probiotic group at the 10th postoperative day, and the type III collagen increased in the 7th. Conclusion: The perioperative use of orally administrated probiotic was associated with a faster reduction of the wound area in rats probably by reducing the inflammatory phase, accelerating the fibrosis process and the deposition of collagen.

title: Centesimal and mineral composition of the fruit in Brazilian genotypes of feijoa (Acca sellowiana)

description: Abstract This research was carried out to evaluate centesimal [dry matter (DM), ash, and crude contents of proteins (CP), fats (CFt) and fiber (CFb)] and mineral composition (Ca, Mg, N, P, K, Fe, Zn, Cu and Mn) of peel and flesh tissues of feijoa fruit (cultivars Alcântara, Mattos, Helena and Nonante, and accession 2316). The genotypes had, in the flesh, DM of 12.10-15.40%, ash of 0.33-0.40%, CP of 0.95-1.45%, CFt of 0.56-1.72%, and CFb of 1.39-2.43%, and in the peel DM of 12.8-17.27%, ash of 0.30-1.49%, CP of 0.56-0.88%, CFt of 0.57-0.90%, and CFb of 2.54-3.98%. The contents of Ca, Mg, K, N and P in the peel were 96-116, 20-30, 1588-3635, 1096-1643 and 68-83 mg kg-1 FW, respectively, and in the flesh were 56-92, 17-29, 1358-2917, 2017-3384 and 255-374 mg kg-1 FW, respectively. Among the micronutrients, Fe had the highest content in peel and flesh tissues (~3.5 mg kg-1 FW). The results show that feijoa fruit represent a dietary source of CP, CFt and CFb, as well as of minerals, especially of P and N in the flesh, and of K and Fe in the peel and flesh tissues.

title: Leadership and management: a study in Non-Governmental Organizations (NGOs) in the metropolitan region of Recife, PE

description: Abstract: The objective of the research is to analyze the relationships between leadership, strategic management practices and the continuity of non-governmental organizations (NGOs). The research will be qualitative. Data collection will be performed through three techniques: semi-structured interviews with the leaders of the institutions, documentary analysis and questionnaire application with leaders and collaborators. The analysis will be done in eight non-governmental organizations with headquarters in the state of Pernambuco. As data analysis technique, the speech analysis method was used. The results showed the relationships of transformational leadership and strategic management practices, among some aspects, with the clear understanding of strategies and the translation of objectives for the entire institution. As for the charismatic leadership characteristics, the high communication capacity was identified, which allows the team to be directed to the objectives. We also observed aspects of transactional leadership that demonstrate a relationship with internal aspects, monitoring of activities, compliance with standards and monitoring errors and deviations committed by the team.

title: Characterization and comparison of yeasts from different sources for some probiotic properties and exopolysaccharide production

description: Abstract A total of 134 strains of yeasts isolated from fruits and vegetables (certain berry fruits, apples, pomegranates, carrots and grapes), free-range chicken feces and dairy products, and from 10 commercial yeast preparations were identified and subjected to analyses to determine their in vitro probiotic properties. Based on 26S rRNA sequence analysis all ten isolates from commercial products were identified as Saccharomyces cerevisiae, and the natural isolates as Candida corpophila, Candida diddensiae, Clavispora lusitaniae, Hanseniaspora opuntiae, Hanseniaspora uvarum, Kazachstania bovina, Kluyveromyces marxianus, Metschnikowia. pulcherrima, Metschnikowia sp., Meyerozyma carribbica, Pichia kluyveri and Wickerhamomyces anomalus. All isolates were found to be resistant to simulated gastric juice at pH 2.5 for 2 h and were able to grow at both 30 and 37 °C. The exopolysaccharide (EPS) production of isolates from commercial preparations and from natural sources varied between 249-275.22 and 27.95-272.22 mg/L, respectively. Two of the natural isolates had levels of EPS production comparable to the natural strains (S. cerevisiae T8-3C and S. cerevisiae P25-1) with 264.63 and 272.53 mg/L, respectively. Isolates were also investigated for autoaggregation and coaggregation abilities. The highest coaggregation ability was determined for the Saccharomyces cerevisiae P25-1 strain against Staphylococcus aureus (ATCC 25923).
