title: Numeric reconstruction of 2D cellular actomyosin network from substrate displacement

description: Introduction: One of the fundamental structural elements of the cell is the cytoskeleton. Along with myosin, actin microfilaments are responsible for cellular contractions, and their organization may be related to pathological changes in myocardial tissue. Due to the complexity of factors involved, numerical modeling of the cytoskeleton has the potential to contribute to a better understanding of mechanical cues in cellular activities. In this work, a systematic method was developed for the reconstruction of an actomyosin topology based on the displacement exerted by the cell on a flexible substrate. It is an inverse problem which could be considered a phenomenological approach to traction force microscopy (TFM). Methods An actomyosin distribution was found with a topology optimization method (TOM), varying the material density and angle of contraction of each element of the actomyosin domain. The routine was implemented with a linear material model for the bidimensional actomyosin elements and tridimensional substrate. The topology generated minimizes the nodal displacement squared differences between the generated topology and experimental displacement fields obtained by TFM. The structure resulting from TOM was compared to the actin structures observed experimentally with a GFP-attached actin marker. Results The optimized topology reproduced the main features of the experimental actin and its squared displacement differences were 11.24 µm2, 27.5% of the sum of experimental squared nodal displacements (40.87 µm2). Conclusion This approach extends the literature with a model for the actomyosin structure capable of distributing anisotropic material freely, allowing heterogeneous contraction over the cell extension.

title: Forestry Clean Development Mechanism and the Heveicuture in the State of Acre, Brazil

description: ABSTRACT The objective of this paper is to generate economic information on rubber tree (Hevea spp.) plantations included in the carbon market under the clean development mechanism (CDM), deployed in the state of Acre, Brazil. To this end, considering data from local heveiculture projects, Net Present Value (NPV), Land Expectation Value (LEV), and Internal Rate of Return (IRR) were quantified for theses reforestations. Based on the results obtained, we conclude that reforestation with rubber trees for carbon sequestration under Forestry CDM may be feasible in the state of Acre, thus strengthening the forest-based economy of the region, provided that the income generated from these plantations is not reduced by more than 20% compared with the average value obtained at the time of this study.

title: Accountability, Corruption and Local Government: Mapping the Control Steps

description: The central purpose of this paper is to map out the Brazilian web of accountability institutions and observe how institutions establish links with each other in order to control corruption cases that reach them. Focus is on institutions that are part of the Brazilian anti-corruption agenda, which include the Federal Public Prosecutor's Office, the Federal Police, the Office of the Comptroller General, the Federal Court of Accounts, the Federal Justice and the Ministries. In the literature, the most widespread argument is that, despite recent institutional improvements, the result produced by this web in terms of coordination is still weak. This article tests this claim by looking at the program called 'Inspections from Public Lotteries'. Through a longitudinal approach, I observed the flux of control activities among the institutions, especially the establishment of investigative and judicial proceedings. Not only I explored the extent to which corruption impacts the establishment of interactions, but I also investigated how the interactions affect the speed of judicial proceedings – using logistic regressions and survival analysis. The conclusion is that the Brazilian web is able to articulate itself in order to hold public officials accountable (something new in this recent democracy), but not in a homogeneous way across all institutions (something the literature has missed). Furthermore, I demonstrate that the entire web of accountability institutions is unable to arrive at a decision in a timely manner.

title: Epidemiology of malocclusion in children and adolescents: a critic review

description: OBJECTIVES: The aim of this literature review about malocclusion was to identify epidemiologic instruments which are being used in Public Health, as well as to bring information regarding the occlusal alterations more prevalent in children and adolescents. METHODS: Information presented in previous studies was reviewed, in articles published in period 1997-2007, considering the production registered in the following databases: Latin American and Caribbean Health Sciences, Scientific Electronic Library Online, International Database for Medical Literature and Brazilian Dentistry Bibliography. RESULTS: The total of 191 identified references, 170 had been eliminated after the implementation of the exclusion criteria and 21 articles met the proposed inclusion criteria and had served of base for this work. The use of different criteria made difficult the comparison of studies in literature and did not offer parameters that can guide the scientific evidences. CONCLUSION: The most used epidemiologic indices were Dental Aesthetic Index and Index of Orthodontic Treatment Need and it was observed predominance of open bite in the deciduous dentition and crowding in the mixed and permanent dentitions.

title: CUSTOMS SYSTEM ORGANIZATION AND TAXATION FIELDS IN THE BRAZILIAN EMPIRE (1808-1836)

description: ABSTRACT This article aims to analyze the organization and operation of Brazilian customs administrative structure, focusing at thetaxes collection transformations and the adaptation of customs system in the first decades of the XIX century. Identifying the increases of income tax revenues and the distinction between the General and Provincial Government taxation field. This paper sets two different moments: the Opening of the Brazilian Seaports to Friendly Nations in 1808 and the changes during the First Reign; and the Liberal Reforms in the 1830’s, with the ratification of the 1832 and 1836 custom regulation. The analysis of this particularities in the Brazilian tax system intend to demonstrate the constant tension between the Center and the others parts, the institutional changes during the transition from the Ancien Régime to Nation State and the different political and economic interests existent in the Brazilian Monarchy.

title: Dental records from the perspective of dentistry students

description: Introduction: Dental records are essential for treatment planning because they collect all relevant information of the patient, besides serving as legal evidence in civil, criminal, ethical and administrative processes and post-mortemidentification. The correct completion and keeping of all forensic dental documentation must continue throughout the undergraduate course and professional life.Objective: To evaluate the perception of dental students, on dental records, their composition and importance.Material and method: It is a descriptive cross-sectional observational survey, in which questionnaires were administered to undergraduate students from the 4th to the 10th semester of a Dentistry Course, at a public University, in the inland of the state of Bahia - Brazil - during the first semester of 2013.Result: Of the 142 interviewed students, 105 participated in the survey; most recognize the documents that should compose the dental records, 98.10% use the manuscript chart, 33.33% state that the keeping time of the records should be ad eternum. The students identify the importance of the records in 93.33% for ethical processes, 97.15% in human identification cases and lawsuits. They request the signature of the patient for the anamnesis' responses in 85.71% and demonstrate ignorance of its importance in other documents that make up the records.Conclusion: It is clear that most of the dental students are unaware about the right keeping time and the need of signing the additional documents.

title: State Program for Urban Mobility of the State of Pernambuco Government (PROMOB): innovative public policies or repetition of the activities undertaken in the past?

description: AbstractThis work is characterized by the proposition of an understanding about the main and most recent public policy for urban mobility implemented by the State of Pernambuco Government, named State Program for Urban Mobility (PROMOB), as well as its analysis and contextualization compared to public policies focused at the same purpose, implemented by previous governments. This study was conducted through a basic qualitative research, based on analysis of documents published by both the state itself, as by other actors inserted in this society, such as the press and civil society organization. Content Analysis was used as data analysis tool. The results from the breakdown of each of the nine projects associated with the program, distributed in eleven analytical categories, indicate that, contrary to the discourse of rulers and some civil society actors’ speeches, relatively little is being done in an effectively different manner from the public urban mobility policies undertaken by previous rulers in the same region.

title: Children in Nature: lived experiences, knowledge and belonging

description: Abstract: This study is about the lived experiences of children in nature and the repercussions in their biopsychosocial development. From a Spinozean perspective, it is understood that everything is constructed from nature, whereby humans are beings of nature and, simultaneously, of culture. The study demonstrates their biophilic condition and discusses the drawings and speech of children from Tupinambá de Olivença and Mura ethnicities and of non-indigenous children from New York, with the aim of our approximating to their ecological knowledge and their feelings in relation to the natural universe of which they are part. This approach is reflected upon within indigenous and urban school education, considering elements of K-12 education guidelines and studies on human rights and the environment.

title: FERMENTATION AND BROMATOLOGICAL COMPOSITION OF SILAGE OF SUGARCANE INOCULATED WITH LACTOBACILLUS BUCHNERI, WITH OR WITHOUT THE ADDITION OF CARBOHYDRATE SOURCES

description: Abstract It was evaluated the fermentative and bromatological aspects of sugarcane silage with addition of Lactobacillus buchneri inoculant with or without the addition of wheat bran (20%), soybean hull (20%) or the mixture of wheat bran (10%) + soybean hull (20%), using a completely randomized design with four replicates. No significant effects of the treatments on the pH of the silage were observed, however, a higher temperature was observed in the treatment containing 10% of wheat bran + 10% of soybean meal in relation to the control treatment. The addition of carbohydrate sources provided an average increase of 145,86 kg of MV/m3 in the specific mass values and, together with the addition of biological inoculant, dry matter recovery averaged 20,5% higher than the control silage, in addition to increasing the dry matter contents in an average of 2,63% and crude protein in 1,92%. It is concluded that, in isolation, the addition of the biological inoculant was only able to reduce losses of the fermentative process in relation to the control silage and that the addition of carbohydrate sources, both soybean peel and wheat bran, improve the nutritive value of the cane silage.

title: EFFECT OF ANTIOXIDANT SUPPLEMENTATION IN DIETS OF ROOSTERS DURING THE POST-PEAK PHASE ON REPRODUCTION AND PRODUCTION CHARACTERISTICS OF OFFSPRING

description: Abstract This study aimed to evaluate the effects of antioxidant supplementation in diets of breeding roosters during the post-peak phase on reproduction characteristics and muscle performance of offspring in two similar breeder houses from a local company. Treatments consisted of a control diet and a diet supplemented with antioxidants (8 ppm canthaxanthin + 40 ppm lycopene + 150 ppm vitamin C). During the 66th week of age, eggs were incubated, and offspring were housed. Dietary supplementation of the blend of antioxidant resulted in higher (p&lt;0.05) weights of testicles, crests, dewlaps, dewlap thickness, and number of perforations (53.35 x 25.30) in relation to non-supplemented roosters. There was no significant effect (p&gt;0.05) of supplementation of the antioxidant blend on weight gain and breast weight and count and diameter of muscle fibers of offspring at 7 days of age. Feed conversion and weight gain from 14 to 35 days were better (p&lt;0.05) in offspring from supplemented roosters. The supplementation of an antioxidant blend in roosters improved reproductive characteristics assessed and feed conversion and weight gain of offspring.
