title: Estimating design hydrographs at the basin scale: from event-based to continuous hydrological simulation

description: ABSTRACT Design hydrographs are widely used in practical hydrologic engineering problems. Typical applications adopt event-based (EBM) methods, using rainfall-runoff models to convert design hyetographs into design hydrographs. Uncertainties include the definition of antecedent conditions and the assumption of equivalence between hyetograph and hydrograph return periods. An alternative is to use continuous simulation (CSM) methods, by forcing a rainfall-runoff model with long precipitation series, and directly analyzing the output discharges. To better understand uncertainties in the EBM method and differences between CSM and EBM ones, we applied a hydrological model in the Itajaí-Açu river basin to compare a CSM method with 730 different simulations of an EBM one, considering different basin antecedent conditions and design hyetographs (10- and 50-years). Results indicated that the EBM method leads to a large range of design discharges depending on the antecedent condition. CS-based 10- and 50-years maximum discharges corresponded to percentiles between 30% and 50% of the EBM estimates. Higher discharge variation occurred in sub-basins with larger maximum soil water storage. Our conclusions agree with the literature, which points towards CSM-based methods to estimate design discharges.

title: Arterial stiffness in hyperthyroid patients is deteriorated due to thyroid hormones

description: ABSTRACT Objective The aim of this study is to evaluate and compare arterial stiffness, which is an independent risk indicator for cardiovascular diseases (CVDs), between patients with overt hyperthyroidism, subclinical hyperthyroidism, euthyroidism by antithyroid therapy and healthy volunteers with pulse wave analysis (PWA). Subjects and methods A total of 102 volunteers were included in the study (30 in the overt hyperthyroid group, 28 in the subclinical hyperthyroid group and 14 with euthyroidism by antithyroid therapy and 30 healthy). The arterial stiffness measurements of the participants in the study were performed with the Mobil-O-Graph PWA device (I.E.M. GmBH, Stolberg, Germany), which makes cuff based oscillometric measurement from the brachial artery. Results Systolic blood pressure, pulse rate, central systolic blood pressure, cardiac output, heart rate-corrected augmentation index (Aix@75) and pulse wave velocity (PWV) measurements were significantly higher in the hyperthyroid group than in the control group. The heart rate and PWV in the subclinical hyperthyroid group were significantly higher than the control group. In the euthyroid group, systolic blood pressure, central systolic blood pressure, cardiac output, cardiac index and PWV were found significantly higher than the control group. There was also a negative correlation between Aix@75 and thyroid-stimulating hormone (TSH), and a positive correlation between Aix@75 and free thyroid hormones. Conclusion In our study, we observed that the arterial stiffness was adversely affected by an overt or subclinical increase in thyroid hormones and this correlated with thyroid hormone levels. We recommend that PWV measurement, which is a simple method for detecting CVD risk, can be used in these patients.

title: Sample Size for Height and Diameter Evaluation of Timbauva Plants

description: ABSTRACT The objective was to estimate the sample size to evaluate height (H), collar diameter (D) and relation height/collar diameter (HD) of timbauva plants (Enterolobium contortisiliquum) and to verify its variability among tubes, dosages of fertilizer and ages of evaluation. Ten treatments were organized in blocks designed with four replication and formed by the combination of sizes of tubes (110 and 180 cm3) and dosages of fertilizer (0, 3, 5, 7 e 9 g L-1 of substrate). The H, D and HD variables were evaluated in five ages. The sample size to evaluate H, D and HD is dependent on age evaluation. For the tubes, dosages of fertilizer and ages of evaluation, 22 plants per experimental unit (pot) are enough to predict the plants variables, with estimation error equal to 10% of estimated average, with a reliable rating of 95%.

title: Biodiversity Conservation in Agricultural Landscapes: the Importance of the Matrix

description: ABSTRACT Agricultural matrices can lead to landscape homogenization, culminating in losses of biodiversity and ecosystem services. Agricultural management is determinant for developing conservation strategies. In this review, we discuss the influence of the agricultural matrix on biodiversity at different scales. Intensive agriculture under agrochemicals and synthetic fertilizers aggravates forest fragmentation processes, compromising conservation habitats. On the other hand, managed matrixes with greater agricultural biodiversity and reduced synthetic inputs tend to favor species’ persistence. There is discord regarding the best model to conserve biodiversity in agricultural landscapes, but the land sharing system increases the landscape heterogeneity, ensures food production, and constitutes a safer approach from the socioecological perspective. Future studies should consider the matrix identity and management to assess fragmentation effects and its ability to harbor biodiversity.

title: Compliance with Environmental and Social Legislation in Certified Forestry Companies

description: ABSTRACT The objective of this study was to evaluate the contribution of the FSC forestry certification system to improve the forestry sector, in terms of compliance to environmental and social laws and improvements in working conditions resulting from the certification process. Thirty-seven auditing reports from five Brazilian forestry companies were evaluated, throughout the 2006-2013 period. Non-compliance and observations were analyzed and organized into categories, which identified the main performance issues found in certified forestry organizations. 301 instances of non-compliance and 138 observations of audit reports were verified, where 48 and 57% respectively, were linked to the two principles studied. For obtaining and/or maintaining the certificate it is necessary for all violations to be resolved. Therefore, it was concluded that forest certification contributes to the advancement of the forestry sector in Brazil, in relation to compliance with legal, social and labor issues.

title: Application of indices for water resource systems stress assessment

description: ABSTRACT This paper aims to present a methodology to conduct a water stress assessment of water resources systems through indices. The proposed methodology was applied to Cantareira System, which is one of the most important water supply systems of São Paulo Metropolitan Region (SPMR). The authors used two indices to support this evaluation: Normalized Deficit Index (NDI) and Normalized Deficit Cumulated (NDC). Both of them consider only the natural flow as the renewable source of water (supply), and account for natural and anthropic uses of this water (demand) as a way to determine the dependence level that the area relies on endogenous and/or exogenous sources of water to meet its needs. To support this assessment, two meteorological drought indices were used as well: the Standardized Precipitation Index (SPI) and Drought Magnitude (DM). The diagnosis of a water supply system, a country, region or even district, based on indices that represent the local water risk, is extremely important not only to bring a better understanding of extreme events, such as droughts and floods, but also to support strategic decision-making process regarding water resources management. This sort of assessment is a useful tool, for instance, in indicating eventual necessity of water storage, such as large reservoirs, or interbasin water transfers, which could improve the water security levels of the study unit.

title: Searching for mutations in the HNF1B gene in a Brazilian cohort with renal cysts and hyperglycemia

description: ABSTRACT Objective To verify the presence of variants in HNF1B in a sample of the Brazilian population selected according to the presence of renal cysts associated with hyperglycemia. Subjects and methods We evaluated 28 unrelated patients with clinical suspicion of HNF1B mutation because of the concomitant presence of diabetes mellitus (DM) or prediabetes and renal cysts. Genotyping was accomplished using Sanger sequencing or multiplex ligation-dependent probe amplification (MLPA). In positive cases, available relatives were recruited. Results We found two patients with HNF1B mutations. The first presented the variant p.Pro328Leufs*48(c.983delC) and had DM, renal cysts, and hypomagnesemia. The second presented a heterozygous whole gene deletion in HNF1B, DM, renal cysts, body and tail pancreatic agenesis, and hypomagnesemia; this alteration was also found in his two siblings and his father. Conclusion The recruitment of suspected cases of HNF1B gene mutations in Brazilians due to hyperglycemia and renal cysts presents two positive cases. Our cases contribute to the annotation of clinical and biochemical phenotypes of this rare form of maturity-onset diabetes of the young (MODY).

title: Residential location in a vertical city: a syntactic study in Florianópolis

description: Abstract A substantial portion of urban growth is motivated by profit seeking, which is related to location, the main component of land value. The verticalization is one of the strategies for obtaining larger profits from urban land, since the high cost of land leads developers to increase the number of floors in order to maximize the returns of their investment. The aim of this study is to investigate the configurational characteristics of the streets in which residential verticalization occurred in Florianopolis. In order to do this, we used the theory of Space Syntax and its two main measures, integration and choice. We found that the logic of vertical residential buildings location in Florianopolis is better revealed by local choice measure (R3), that is, there is a greater concentration of vertical residential buildings in streets used to access other parts of the system within a local area. However, this is also tied to the historical process of urbanization, with older and more consolidated areas showing a tendency to occupy its more integrated and higher choice streets up until a certain point in time, and then proceeding to occupy the more interiorized portions of the grid.

title: Combined water treatment with extract of natural Moringa oleifera Lam and synthetic coagulant

description: Abstract This study evaluated the efficiency of coagulation/flocculation, sedimentation and filtration processes using the combination of natural coagulant from Moringa oleifera Lam (MO) and synthetic coagulant aluminum polychloride (PAC) for water treatment. Raw water was obtained from the Pirapó River Basin, Maringá, Paraná State, Brazil. Coagulation/flocculation and sedimentation assays were carried out in a Jar Test. A two-layer rapid filter filled with sand and anthracite was used in the filtration stage. Water quality and therefore the efficiency of the process were determined by means of the analysis of physical, chemical and bacteriological parameters, including the determination of floc size and zeta potential. The utilization of MO contributed to the reduction of the required demand of synthetic coagulant PAC. The association of coagulants, with 80%/20% or 60%/40% of MO/PAC, ensured an improvement of water quality parameters, such as apparent color, turbidity and UV254nm, as well as the possibility of water production with adequate potability standard.

title: Determination of Strategic Orientation of the Alto Vale do Rio Negro Furniture Pole

description: ABSTRACT The objective is to identify and characterize the competitive strategy developed by the furniture production center of the Alto Vale do Rio Negro from the three generic strategies proposed by Porter (1980): low cost, differentiation and focus. The identification of strategies was through a questionnaire and correspondence analysis. In general, companies are exporters, medium-sized or small, producing residential furniture, custom straight or serially. Data analysis showed that the group of companies analyzed does not have a generic pure strategy because the differentiation and low cost strategies were considered equally important. It was found that the companies with most of their production for foreign markets adopting a low cost strategy and large companies pursuing a strategy of differentiation and low cost simultaneously.
