title: Drying Kinetics of Cecropia pachystachya Leaves

description: ABSTRACT The species Cecropia pachystachya has important medicinal purposes and its leaves have been used in pharmaceutical research, so the drying of this product may help maintaining its chemical properties and ensure safe storage. Thus, the objective of this study was to select mathematical models to represent the drying kinetics of Cecropia pachystachya leaves, determine the effective diffusion coefficient and obtain the activation energy during drying at different temperatures. Leaves were dried in an oven under five temperature conditions (40, 50, 60 and 70 °C), until reaching hygroscopic equilibrium moisture content. Among the models analyzed, the Logarithmic model best represented the drying kinetics at temperatures of 40 and 60 °C, whereas Modified Henderson & Pabis and Dryceleaves represented temperatures of 50 and 70 °C, respectively. The effective diffusion coefficient increased with increasing air temperature, and the activation energy for liquid diffusion in the drying process was 64.53 kJ mol-1.

title: Impact of Risk Factors for Coronary Artery Disease on Hospital Costs of Patients Undergoing Myocardial Revascularization Surgery in the Brazilian Unified Health System (SUS)

description: Abstract Background: Cardiovascular diseases are a major cause of mortality and morbidity. Myocardial revascularization surgery may be indicated for the relief of symptoms and to reduce mortality. However, surgery is a costly procedure and the impact of the number of cardiovascular risk factors on the cost of the procedure has not been established. Objectives: To identify the impact of risk factors for coronary artery disease on myocardial revascularization surgery cost. Methods: We selected 239 patients undergoing myocardial revascularization surgery at the National Institute of Cardiology in the period from 01 January to 31 December 2013. We included patients aged over 30 years, with indication for the procedure. Patients undergoing combined procedures were excluded. Results: Seven patients had only one risk factor, 32 patients had two risk factors, 75 patients had 3 risk factors, 78 patients had four risk factors, 36 patients had 5 risk factors and 11 patients presented 6 risk factors. The total costs, on average, was R$ 14,143.22 in the group with 1 risk factor, R$ 18,380.40 in the group with 2 risk factors, R$ 21,229.51 in the group with 3 risk factors, R$ 24,620.86 in the group with 4 risk factors, R$ 21,337.92 in the group with 5 risk factors and R$ 36,098,35 in the group with 6 risk factors (p = 0.441). Conclusion: This study demonstrates that, in a public referral center for highly complex cardiology procedures, there was no significant correlation between the number of cardiovascular risk factors and hospitalization costs.

title: Influence of water in the MQL technique in the grinding of steel AISI 4340 using CBN wheels

description: Abstract Usually, machining employs cooling methods to avoid high temperatures. In most cases, the cutting fluid is applied with high flow and low pressures. This technique consumes a large amount of cutting fluid that causes serious problems in the environment and in the health of the worker. An alternative to the conventional cooling method is the Minimum Quantity of Lubricant. The MQL attempts to minimize the consumption of cutting fluid, which this study is about, whereby the reduction provided by this MQL was 99.99%. This technique consumes only the necessary quantity of cutting fluid to create a thin film of lubricant on the cutting surface grinding wheel. The MQL aerosol is injected with high pressure in the contact zone, efficiently lubricating the grinding process. However, the cooling effect of MQL is not enough to dissipate all heat produced during the grinding process. This study analyzes the improvement in the cooling effect caused by the addition of water in the MQL. The tests were done using different concentrations of cutting fluid in water, e.g. 1:0, 1:1, 1:3, 1:5 (oil:water). The experiment occurred on the external cylindrical plunge grinding with a vitrified cubic boron nitrite (CBN) grinding wheel, serving as the workpiece, the AISI 4340 quenched and tempered steel. The analyzed outputs were: surface roughness, roundness deviation, acoustic emission and vibration.. The results improved with the addition of water in the cutting fluid used in the MQL technique. The comparison with the MQL conditions showed that the best condition was the fluid with more water concentration.

title: Axes: a new paradigm of regional planning? Infrastructure axes in the national PPAs, in the Iirsa and in the macrometrópole paulista

description: Abstract Our goal is to discuss inter-scalar territorial organization based on the infrastructure axes proposed by the government between 1995 and 2015. Our analysis is grounded on the theoretical framework that shows the relationship between (re)structuring of production and territorial organization (Logan; Molotch, 1987; Scott, 1980; Brenner, 2010). We chose to study planning actions proposed by public initiative. At the federal level: the PPAs and their programs; at the continental level: the plans and proposals of the Iirsa; and at the state level: the Plano de Ação da Macrometrópole Paulista (PAM 2013-2040). Our findings point to the ongoing leading role of the Axis as a structuring element of territorial organization in its different scales, guided by the principles of integration, connectivity and competitiveness.

title: Effect of the age of larvae Ceratitis capitata (Wied.) in the biological quality of parasitoid Diachasmimorpha longicaudata (Ashmead)

description: This work was carried out in order to evaluate the influence of age (size) of larvae Ceratitis capitata used in the rearing of the Diachasmimorpha longicaudataon parasitism, sex ratio of the progeny and the longevity of progeny's females, when the mothers were maintained alone or sharing the same host. Larvae at different ages (five, six, seven and eight days old), in "units of parasitism" were offered to female parasitoids, inside adapted cages, containing one or two seven days old female parasitoids. The number of females of the parasitoid sharing the same "unit of parasitism" in the same cage did not affect any aspect of parasitoid quality. However, the size of the host had significant influence on the number of emerged parasitoids. The youngest host larvae (five days old) reduced parasitism more than larvae at six, seven and eight days old. There was higher emergence of male parasitoids of five and six days old hosts, while more females emerged from seven and eight days old larvae. The females of D. longicaudata from larvae with six, seven and eight days old lived more than those obtained from females of five days old larvae. When larger host larvae are used in the rearing of parasitoids of fruit flies, it increases parasitism, the number of female progeny and the longevity of female progeny; it can provide economic advantages when used for augmentative liberation on the field.

title: Influence of the Rio Taquaraçu in the water quality of the Rio das Velhas: subsidies for reflections of the case of water shortage in Belo Horizonte metropolitan region – MG, Brazil

description: ABSTRACT Southeastern Brazil is experiencing severe water scarcity because of low rainfall and inefficient water resource management. As a consequence, water supply companies have begun discussing potential solutions to this problem. One proposed solution is creation of new public water supply reservoirs. Recently, managers from municipalities in the metropolitan region of Belo Horizonte, along with sanitation companies, have begun to focus their attention on the Rio Taquaraçu. The Taquaraçu lies in the Rio das Velhas Basin and displays both good water quantity and quality within the Belo Horizonte metropolitan area. The Taquaraçu is a tributary of the Rio das Velhas, and it was proposed that the Taquaraçu waters dilute pollutant concentrations entering the Rio das Velhas, thereby improving downstream water quality. This study evaluated statistically the impact of the Rio Taquaraçu on water quality in the Rio das Velhas. For this analysis, we used data collected between 1997 and 2015 from sampling points established by the Minas Gerais Estate Institute of Water Management(IGAM) in the Rio Vermelho, in the Rio Taquaraçu, and in upstream and downstream sites (the Rio Taquaraçu input) of the Rio das Velhas. Box-plots were created for water quality variables and a Principal Component Analysis (PCA) was run for periods referred to as “dry” and “wet.” Despite receiving sewage releases from cities in its watershed, the Rio Taquaraçu maintains good water quality. Nevertheless, our results indicate that inflow from the Rio Taquaraçu is insufficient to mitigate the poor water quality of the Rio das Velhas.

title: ASSESSMENT OF LEGUMES WITH POTENTIAL USE AS GREEN MANURE IN THE COASTAL TABLELANDS OF PIAUÍ STATE, BRAZIL

description: ABSTRACT Green manure may lead to physical, chemical, and biological improvements to the soil. However, the information on its use in the Brazilian Northeast is scarce. The aim of this study was to assess the phenological cycle and phytomass productivity of seven legume species. This study was conducted in the second semester of 2015 in a completely randomized design with seven treatments and four replications. Plant height, fresh mass of shoot (FMS), dry mass of shoot (DMS), fresh mass of root (FMR), and dry mass of root (DMR) were determined at 100 days after sowing. Germination, flowering, and pod maturation were also assessed. The highest averages of FMS were observed in Crotalaria breviflora and Crotalaria mucronata, followed by Canavalia ensiformis, whereas the highest averages of DMS were observed in C. breviflora, C. ensiformis, C. mucronata, and Cajanus cajan cv. IAPAR 43. The highest averages of FMR were obtained by C. breviflora and C. mucronata, followed by C. cajan cv. Fava Larga. The species C. mucronata, C. cajan cv. IAPAR 43, and C. breviflora presented the highest averages of DMR. In addition, C. juncea, C. ensiformis, and C. cajan cv. IAPAR 43 were the earlier species regarding flowering, while C. cajan cv. Fava Larga was the later species. C. juncea was the earliest among all studied species regarding pod maturation. The tested legume species obtained promising initial results during the assessment period, being able to meet the expectations of biomass production and contributing to soil sustainability in this region.

title: A case of bilateral hypertrophy in the chelae of a male specimen of Minuca rapax (Smith, 1870) (Decapoda, Brachyura, Ocypodidae)

description: Abstract The present study describes the first record of bilaterally hypertrophied chelipeds in a male fiddler crab, Minuca rapax (Smith, 1870), collected in the mangrove area near the city of Jaguaribe, located in the northern portion of Itamaracá Island in Pernambuco, Brazil. This particular specimen was captured by hand as it emerged from its burrow. Of the total 126 individuals (48 females and 78 males) of the genus Minuca (Bott, 1954) captured, only one presented chelipeds similar in size and shape. Some of the causes of malformation in decapods have been attributed to a double generation of growth areas or non-synchronous regenerative coordination in wound healing. Due to the lack of studies on the definitive cause of these abnormalities and deformations, further investigations are required to determine the roles of individuals with abnormalities within populations as well as the principal causes of these abnormalities.

title: Urban accumulation downturn in Brazilian cities: the state crisis in view of the market crisis

description: Abstract The simultaneity between the economic crisis of the Brazilian state and the crisis of the real estate market raises the hypothesis that there has been a downturn in the urban accumulation process in Brazilian cities. Both crises are situated in the broader context of the global economic crisis that has been affecting developed and peripheral capitalist countries since 2008. In Brazil, it has been associated with a political governability crisis that has had implications for governance arrangements based on public-private partnerships, and also for entrepreneurship models that have supported large urban projects conducted by strategic planning policies in states and metropolitan municipalities in recent years. This article evaluates the sustainability capacity of the urban accumulation dynamics in view of the downturn in real estate production.
