title: Deforestation Dynamics in the Nova Bonal Sustainable Development Project, Acre, Brazil

description: ABSTRACT This study assessed the dynamics of the land use and cover changes, deforestation trends and the current status of the Legal Forest Reserves (LFR) and Permanent Protected areas (PPA) in the Nova Bonal Sustainable Development Project (SDP) between 1997-2014. Deforestation datasets and fieldwork were used in this analysis. Our results indicate that there was no trend in the estimated deforestation rate dataset for the SDP, but there was a decreasing trend in deforestation rates within its 10-km buffer zone, most likely due to the scarcity of native forests in that area. The negative environmental area balance of PPA and LFR were observed within the 10-km buffer zone of the SDP. Finally, we conclude that the alternative land and forest uses enforced within the SDP are more effective for environmental conservation than the commonly adopted land uses, especially pastures adopted by conventional colonization located around it.

title: Physical-mechanical Properties of Plywood Produced With Acrocarpus fraxinifolius and Pinus oocarpa

description: ABSTRACT The present study has the objective of evaluating the physical-mechanical properties of plywood produced with Acrocarpus fraxinifolius wood, as well as the effect of combining their veneer with Pinus veneer. The wood of Acrocarpus fraxinifolius and Pinus oocarpa were used in the production of the panels. The plywood was produced with five veneers; the adhesive used was phenol-formaldehyde, weighing 320 g.m-2. The evaluated properties were: equilibrium moisture (EM), specific mass (SM), water absorption (WA), thickness swelling (TS), shear strength (SS), modulus of rupture (MOR) and modulus of elasticity (MOE) both parallel and perpendicular to the fibers. No statistical difference was observed in the EM and TS, whereas all other properties showed statistical differentiation between the treatments. In general, the use of Acrocarpus fraxinifolius veneers improved the physical-mechanical properties of the compensated ones. Thus, the use of this species in the production of plywood is technically feasible.

title: Establishment of Leguminous Trees in the Soil of a Shooting Range

description: ABSTRACT Shooting range activities risk contaminating the soil, posing potential risks to human health, the local biota, and water sources. Considering that soil organisms are the first to be affected by contamination, this study aimed to evaluate the initial growth of the leguminous tree Albizia polycephala and its association with microbes in soil taken from this area. The collected soil was placed in 60-ml tubes with legume seeds and stored in a greenhouse for 60 days. The differences in the legumes’ growth were not related to the physical and chemical properties of the soil, nor to its metal content, but rather to mycorrhizal colonization and nodulation, which were shown to be effective in creating favorable conditions. This indicates that the site under study has great natural potential for the establishment of tree species, which could be impaired if it continues to be used for shooting practice.

title: housing provision alternatives in Brazil, Hong Kong and the United Kingdom

description: In developed countries, such as the UK, France, Sweden and Canada, or even in less developed countries, such as India, Malaysia and China, there are systems of housing provision that include social rental housing as one of their major pillars. For different reasons, a mixed housing provision system is necessary, be that to promote homeownership or to promote rental housing – in private or public hands. In Brazil, however, there has been little effort to establish a proper public social rental housing system. This is less because of economic restrictions than for political and ideological reasons. This paper discusses two systems of housing provision in Brazil – that of the Armed Forces and the PAR (Programa de Arrendamento Residencial). Two other international social housing systems are analyzed – the one in the UK and the other in Hong Kong. The analysis of all four cases is here held in order to look for hints for the making of proposal for a social rental housing sector in Brazil. Several aspects were analyzed, especially their management formats, including repair and maintenance policies, that grant housing stocks longevity and resilience in the urban environment.

title: Geotechnology as a Planning Tool in the Determination of Forest Extraction Costs

description: ABSTRACT The objective of this work was to use the geotechnology study as a planning tool in determining the costs of forest extraction. The research was carried out in areas of the Forest Company that operates in the southern region of Bahia, Brazil. The work was developed in two stages, the first corresponding to the determination of production costs of the forwarder and the second in the machine’s productivity, taking as parameter the project area and the distance of extraction. The proposed methodology allowed to estimate with precision the distance of extraction, being this variable of great influence in the costs of forest extraction. The evaluated project presented 256.30 hectares of eucalyptus plantation, divided into 10 plots, with an extraction mean distance of 200 meters. According to the study, it would require the value of US$ 102,575.33 for the extraction of the wood from the project evaluated.

title: A COMPARISON OF NONLINEAR MODELS FOR DESCRIBING WEIGHT-AGE DATA IN ANGLO-NUBIAN DOES

description: ABSTRACT The objective of this study was to determine the optimum age at last weighing and compare the goodness of fit of nonlinear models used to fit longitudinal weight-age data to describe the growth pattern of Anglo-Nubian does. Weights of 104 animals from birth to 60 months of age were grouped into 10 age groups at six-month intervals. In each age group, parameters A (asymptotic weight), B (integration constant), and K (maturity index) were estimated using the Brody, Gompertz, logistic, and von Bertalanffy models. Data were analyzed using analysis of variance in a factorial design (10 age groups × 4 nonlinear models). The age group × model interaction was not significant. Mean estimates of A, B, and K were significantly different between age groups up to 30 months (p &lt; 0.05), indicating that the estimated curve is affected by weights taken before this age independent of the model. The values of mean squared error (MSE), mean absolute deviation (MAD), coefficient of determination (R2) and Rate of convergence (RC) at each age group up to 30 months were compared to determine the goodness of fit of nonlinear models. The ranking of fit was logistic, Brody, von Bertalanffy, and Gompertz. The logistic and Brody models respectively estimated the smallest and largest asymptotic weight. Longitudinal weight records taken until 30 months of age are most appropriate for estimating the growth of Anglo-Nubian does using nonlinear models.

title: Thyroid nodules ≤ 1 cm and papillary thyroid microcarcinomas: Brazilian experts opinion

description: ABSTRACT The indolent evolution of low-risk papillary thyroid microcarcinoma (mPTC) in adult patients and the consequences of thyroidectomy require a revision of the management traditionally recommended. Aiming to spare patients unnecessary procedures and therapies and to optimize the health system in Brazil, we suggest some measures. Fine-needle aspiration of nodules ≤ 1 cm without extrathyroidal extension on ultrasonography should be performed only in nodules classified as “very suspicious” (i.e., high suspicion according to ATA, high risk according to AACE, TI-RADS 5) and in selected cases [age &lt; 40 years, nodule adjacent to the trachea or recurrent laryngeal nerve (RLN), multiple suspicious nodules, presence of hypercalcitoninemia or suspicious lymph nodes]. Active surveillance (AS) rather than immediate surgery should be considered in adult patients with low-risk mPTC. Lobectomy is the best option in patients with unifocal low-risk mPTC who are not candidates for AS because of age, proximity of the tumor to the trachea or RLN, or because they opted for surgery. The same applies to patients who started AS but had a subsequent surgical indication not due to a suspicion of tumor extension beyond the gland or multicentricity. Molecular tests are not necessary to choose between AS and surgery or, in the latter case, between lobectomy and total thyroidectomy. The presence of RAS or other RAS-like mutations or BRAFV600E or other BRAF V600E-like mutations should not modify the management cited above; however, the rare cases of mPTC exhibiting high-risk mutations, like in the TERT promoter or p53, are not candidates for AS.

title: Social participation in the Brazilian Supreme Court: rethinking the role of public hearings

description: Abstract Public hearings in the Brazilian Supreme Court (STF) is announced as a mechanism that produces information in the judicial review process, that democratizes the court and legitimizes its decisions. Nevertheless, empirical observation and analyses of official documents of the Court reveals a mismatch between practice and discourse around them. This article questions that main narrative and proposes an alternative view of public hearings as a lobby tool.

title: CHEMICAL COMPOSITION OF SWINE WASTEWATER, SOIL, AND TIFTON 85 AFTER 8 YEARS OF APPLICATION

description: ABSTRACT The aim of this study was to evaluate the chemical composition of swine wastewater (SW), and its effect on the chemical attributes of soil and plants in a long-term experiment. The area was designed for an 8-year hay production, using Tifton 85 grass (Cynodon spp.), with an average annual application of 360 m3 ha-1, divided into 6 applications. Also, soil chemical composition was evaluated at 0.0-0.20 and 0.20-0.40 m of depth, and the chemical composition of plant and vegetable materials on the ground were evaluated for two months (November and June). Concentrations of N, Ca, and Cu in SW did not decrease from the affluent to the storage lagoon. It was observed that the content of Cu, Zn, and Mn was classified as in excess in soil that could be a consequence of high levels of these micronutrients utilized in rations of swine in the SW supplier farm, mainly in the rations of piglets combined with a low extraction of these nutrients by plants. In relation to micronutrients and P (46.08 mg dm-3) in the soil, these should be evaluated in greater depth than performed in the present study, because the concentrations did not vary considerably among depths and were high. The concentrations of Cu and Zn were high in shoot plants with an average of 133.0 and 139.30 mg kg-1, respectively. The continuous use of SW should be monitored continuously through analyses of soil and waste, and alternatives must be researched to reduce the concentration of micronutrients and P in SW.

title: Senses of the metropolis: a conceptual balance based on publications of Cadernos Metrópole

description: Abstract The purpose of this text is to contribute to the understanding of how the metropolis and metropolization have been conceptually approached in the articles published in the scientific journal Cadernos Metrópole. This journal specializes in the metropolitan theme and has been published for two decades, without interruption, covering exactly the period in which this object regained a marked conceptual vigor. Initially, a bibliometric survey was carried out to identify the concepts most used in the published texts. This was complemented by the reading of the texts, searching for references of the theoretical-conceptual matrix that guided them.

title: Red-Yellow Latosol Penetration Resistance Under Different Subsoiling Depths

description: ABSTRACT The objective of this work was to evaluate the penetration resistance (PR) of a red-yellow latosol submitted to two subsoiling depths for implanting a forest plantation. The subsoiling was evaluated at 40 cm (S-40) and 50 cm (S-50) of depth by determining the soil moisture and soil density, while soil PR was evaluated before and after subsoiling at five points transversely to the subsoiling line (furrow) up to a depth of 60 cm using an electronic penetrometer. The soil density in both treatments was not altered by soil management. Before soil preparation, the soil presented PR values above the critical limit in the 0 cm to 30 cm layers, and after subsoiling a reduction in those values was verified at depth. It can be concluded that the 50 cm (S-50) subsoiling depth is the most suitable for soil preparation in a forest stand implantation.

title: Alternatives to Growth and Yield Prognosis for Pinus caribaea var. caribaea Barrett & Golfari

description: ABSTRACT The objective of this study was to obtain regression equations and artificial neural networks (ANNs) for prediction and prognosis of the yield of Pinus caribaea var. caribaea Barrett & Golfari. The data used for modeling comes from measuring the variables diameter at breast height (DBH) and total height (Ht) in 550 temporary plots and 14 circular permanent plots with 500 m2 in Pinus caribaea var. caribaea plantations, aged between 3 and 41 years old. In growth prediction, the results indicated Schumacher model as the best fit to the data. On prognosis, the modified Buckman system was better than Clutter’s. ANNs presented a similar performance to the Buckman model in volume prognosis, however these were superior for basal area prognosis.
