title: Selective Logging Detection in the Brazilian Amazon

description: ABSTRACT Selective logging activities are commonly observed in the Brazilian Amazon and are responsible for high forest impact. In this study, selective logging detection techniques and the spatiotemporal extension of forests impacted by logging activities between 2003 and 2014 in portions of the states of Mato Grosso, Pará, and Rondônia were assessed using remotely sensing data. Based on results obtained, it was estimated that the overall accuracies are greater than 91% for techniques applied to detect forests impacted by selective logging in the study areas. Forests impacted by selective logging increased in Western state of Mato Grosso and Northern state of Rondônia, which indicates a stage high forest activity in these regions. In contrast, in Eastern state of Pará, a decrease in forests impacted by logging activities was observed, which indicates collapsed stage of logging activities resulting from deforestation and predatory logging in that region.

title: Comparative study of periodicity estimation methods using ultrasonic signals

description: Abstract Introduction Various signal-processing techniques have been proposed to extract quantitative information about internal structures of tissues from the original radio frequency (RF) signals instead of an ultrasound image. The quantifiable parameter called the mean scatterer spacing (MSS) can be useful to detect changes in the quasi-periodic microstructure of tissues such as the liver or the spleen, using ultrasonic signals. Methods We evaluate and compare the performance of three classic methods of spectral estimation to calculate the MSS without operator intervention: Tufts-Kumaresan, SAC (Spectral Autocorrelation) and MUSIC (MUltiple SIgnal Classification). Initially the evaluations were performed with 10,000 signals simulated from a model in which the variables of interest are controlled, and then, real signals from sponge phantoms were used. Results For the simulated signals, the performance of all three methods decreased with increasing Ad or jitter levels. For the sponges, none of the methods accurately estimated the pore size. Conclusion For the simulated signals, Tufts-Kumaresan had the lowest performance, whereas SAC and MUSIC had similar results. For sponges, only Tufts-Kumaresan was able to detect the increase in the size of the pores of the sponge, although most often, it estimated sizes larger than expected.

title: HPGR as alternative to fused alumina comminution route: an assessment of circuit simplification potential

description: Abstract A considerable portion of energy consumption and, as a consequence, operational costs in mineral processing, is associated with comminution. High Pressure Grinding Rolls (HPGR) are appealing for their energy efficiency and resulting lower operating costs. This article evaluates this technology as an alternative to the conventional fused alumina comminution route of a specific plant comprising a complex roll crushing circuit. Two fused alumina samples, called BT and TB, were submitted to HPGR (open circuit) and physical characterization (DWT, BBWI, bulk density, specific gravity) tests. In addition, simulations were conducted using JKSimMet® 6.0 software, aiming to predict the performance of a closed circuit equipment and scale-up of an industrial-scale unit. Product size distributions of the open circuit HPGR tests and closed circuit HPGR simulations were compared with the product size distribution required by the industrial comminution circuit. The required throughput was also evaluated. Results show that the alternative HPGR route provides a remarkable potential for circuit simplification, while considerably reducing the number of comminution equipments from 13 to 1, which facilitates operational control and possibly reduces operating costs.

title: The critical success factors for organizational performance of SMEs in Malaysia: a partial least squares approach

description: Abstract Purpose: This paper seeks to examine the relationship between the determinants of organizational performance such as top management support, customer focus, employees’ orientation, technology orientation, and entrepreneurial orientation in Malaysia. Design/methodology/approach: A quantitative research design was applied for this study. Data was collected through survey questionnaires applied to business owners and senior managers working in SMEs located in three Malaysian states, using purposive sampling technique. SmartPLS 2.0 (M3) was applied to test the hypotheses. Findings: The findings suggest that both technology and entrepreneurial orientations are significant success factors for SMEs in terms of financial and non-financial performance. In addition, top management support is found to be significantly and positively related to financial performance. Originality/value: The empirical analysis indicates that technology orientation and entrepreneurial orientation add more value to organizational performance. Therefore, it is vital for SMEs to focus on these two critical success factors in order to improve their performance.

title: IS ETHANOL STABILITY OF MILK A RELIABLE TEST?

description: Abstract The alcoholic stability of milk is a current problem in many countries that still use the alcohol test to measure the microbiological quality of milk. Beyond microbiological acidity, many factors can also affect the alcoholic stability of milk, leading to a confounding effect in alcohol test and industrial losses. The present study aimed to evaluate the relationship between pH, bacterial count, Dornic acidity, lactose percentage and ethanol stability of milk. The samples comprised fresh raw milk from 322 dairy farms from Parana state. According to the results of the 72º ethanol test and the Dornic acidity test, the samples received the following classification: stable milk, acidic milk, or unstable milk to ethanol. There was no relationship among pH, Dornic acidity and microbiological count in samples of milk that were unstable to alcohol test. Unstable milk to ethanol has pH values ranging between 6.6-6.8 with low microbiological count (less than 105 cell.mL-1) and higher lactose percentages (up to 4.5%). As bacterial count increase, the lactose percent tends to decrease, but not necessarily together. This feature makes the alcohol test unreliable, and the use of other parameters is strongly recommended such as thermal stability, lactic acid titration, pH, and clot-on-boiling test.

title: Analysis of interventions and socio environmental factors associated with the occurrence of trachoma in Pernambuco in two surveys on schoolchildren conducted in 2006 and 2012

description: Abstract Trachoma is the main cause of preventable blindness in developing countries. This paper aims to describe the trachoma situation in the schools of Pernambuco, Brazil, noting guidelines for the control program and analyzing a possible association of the prevalence rates obtained by research in 2006 and 2012 with socioeconomic, demographic and ecological health factors. A descriptive ecological study was performed, using secondary data from investigations within Pernambuco public schools (investigating 79 cities in 2006 and 22 in 2012). Due to the small number of patients examined in 2006, the prevalence numbers estimative was rather inaccurate, methodologically impairing the choice of the 22 cities considered priorities for the SANAR programme in 2012. However, it was only possible to confirm the reduction of Trachoma prevalence in 5 among the 22 priority cities investigated. Demographic studies shall be done and the containing measures shall be reviewed in the state, since the investigation layout is still based in punctual actions campaigns, without the development of other continuous and effective measures that reduce the active types of the disease in order to eliminate Trachoma as a cause of blindness in Brazil.

title: Housing and public policy: what has been researched about it?

description: Abstract Objective with this article to review scientific literature on the Brazilian housing policy, from 1964 to 2014 in order to understand how this issue has been studied by management and other areas of Applied Social Sciences. Therefore, we performed a meta-study that was systematized in three stages: (i) selection of literature to be analyzed; (ii) collecting the information and (iii) the analysis, interpretation and presentation of results. The content analysis technique, subdivide the steps of pre-analysis, material exploration and treatment of results supported the construction of the proposal. Some interesting results: predominance of the gauchos and São Paulo researchers, belonging mainly to the Federal University of Rio Grande do Sul and São Paulo University; and the use of evaluative nature of research involving housing programs nationwide, as the Minha Casa, Minha Vida and the Residential Leasing Program implemented at local level. On the other hand, certain shortcomings were identified: the direction of studies on housing provision, that is, building houses with little production involving other perspectives of housing policy, as the reform and regularization of slums; and the predominance of research in urban context indicating the lack of research focusing on rural housing.

title: Bibliometric analysis of multi-language veterinary journals

description: Abstract The purpose of this study was to investigate the association between language and total number of citations found among documents in journals written in English and other languages. We selected all the journals clustered together in the Journal Citation Reports 2014 under the subject category “Veterinary Sciences” and downloaded all the data registered between 1994-2013 by Web of Science for the journals that stated publishing documents in languages other than English. We classified each of these journals by quartile and extracted information regarding their impact factor, language(s) stated, country of origin, total number of documents published, total number of reviews published, percentage of documents published in English and the quartile in which each journal ranked. Of the 48,118 documents published by the 28 journals analyzed, 55.8% were published in English. Interestingly, although most of the journals state being multi-language, most documents published in quartile 1 journals were in English (an average of 99.2%), while the percentage was 93.1% in quartile 2 journals, 62.1% in quartile 3 journals and 27.4% in quartile 4 journals. We also confirmed that citation distribution in these journals was highly skewed. The results of this study suggest that journals should consider adopting English as the main language as this will increase citation counts and the impact factor of the journal.

title: A bilinear elastic constitutive model applied for midpalatal suture behavior during rapid maxillary expansion

description: Introduction : This study aims to evaluate the influence of the biomechanical behavior of the midpalatal suture (MPS) during the rapid maxillary expansion (RME) when modeled by the Finite Element Method. Methods Four simulation alternatives are discussed and, for each analysis, the suture is considered as a functional unit with a different mechanical behavior: (i) without MPS elements, (ii) MPS with Young's modulus (E) equal to 1 MPa, (ii) MPS with E equal to 0.01 MPa and (iv) MPS with bilinear elastic behavior. Results The stress analysis showed that, when MPS is not considered in the model, stress peaks are reduced in magnitude and their distribution is restricted to a smaller area when compared to the model with the inclusion of MPS (E=1 MPa). The increased suture stiffness also has a direct influence on MPS displacements after 30 expander activations. Conclusion The consideration of the MPS in RME computer models influences greatly the calculated displacements between the suture bone ends, even as the stress levels in maxillary structures. Furthermore, as proposed for the described model, the elastic bilinear behavior assigned to MPS allows coherent prediction of stresses and displacements results, being a good representation for this suture overall behavior.
