title: Vignettes: a data collection technique to handle the differential operation of items in surveys

description: ABSTRACT Vignettes are scenarios used in many areas of academic research, whose main application is related to situations in which judgments about people are subject to biases or distortions. Despite the wide use of vignettes in surveys, the recommendations for their creation are limited in the literature. Thus, this study aims to review and describe criteria presented in the literature for robust textualization of vignettes. This study presents a literature review on the use of vignettes and describes a minimum set of criteria (plausibility, clarity, simplicity, content validity and analogy between the vignette and the construct) for the judicious application of this methodology. They have presented four vignettes constructed from the literature review and validated by panel of experts, with the purpose of capturing the perception of respondents on the protagonists' actions in scenarios about co-creation value in a health service. In this way, the study conceives the essential elements for the development of this methodology.

title: Economic advantages of dynamic analysis in the early stages of mining projects

description: Abstract The use of dynamic simulation is technically advantageous for the project as shown by various authors. However, is it economically advantageous in the early stages of the project (FEL1 and FEL2)? The methodology to economically evaluate the use of dynamic simulation considers the time and development cost compared with the time and cost spent to change the project in the next phase, considering changes that could be avoided with the use of dynamic simulation. Five process plant projects were evaluated, each one with an estimated CAPEX of US$ 300 million. The saved average is US$ 44,200.00 and US$ 182,400.00 for FEL 1 and FEL 2 respectively. The percentage cost savings for FEL2 (2.0%) and FEL3 (3.1%) are significant. The estimated delay avoided for FEL2 (3 weeks) and FEL3 (8 weeks) is directly related to the implementation delay, whose cost is expressively greater than the savings shown. The study concludes that the use of dynamic simulation is economically advantageous for the project.

title: Geochemistry of the alkaline volcanicsubvolcanic rocks of the Fernando de Noronha Archipelago, southern Atlantic Ocean

description: The Fernando de Noronha Archipelago presents, on its main island, a centrally-located stratigraphic unit, the Remédios Formation (age around 8 - 12 Ma) constituted by basal pyroclastic rocks intruded by dikes, plugs and domes of varied igneous rocks, capped by flows and pyroclastics of mafic to ultramafic rocks of the Quixaba Formation (age around 1 - 3 Ma), which is limited from the underlying unit by an extensive irregular erosion surface. A predominant sodic Remédios series (basanites, tephrites, tephriphonolites, essexite, phonolites) can be separated from a moderately potassic Remédios sequence (alkali basalts, trachyandesites, trachytes), both alkaline series showing mostly continuous geochemical trends in variation diagrams for major as well as trace elements, indicating evolution by crystal fractionation (mainly, separation of mafic minerals, including apatites and titanites). There are textural and mineralogical evidences pointing to hybrid origin of some intermediate rocks (e.g., resorbed pyroxene phenocrysts in basaltic trachyandesites, and in some lamprophyres). The primitive Quixaba rocks are mostly melanephelinites and basanites, primitive undersaturated sodic types. Geology (erosion surface), stratigraphy (two distinct units separated by a large time interval), petrography (varied Remédios Formation, more uniform Quixaba unit) and geochemistry indicate that the islands represent the activity of a protracted volcanic episode, fueled by intermittent melting of an enriched mantle, not related to asthenospheric plume activity.

title: Reconstruction of gait biomechanical parameters using cyclograms and artificial neural networks

description: Abstract Introduction Historically, assessing the quality of human gait has been a difficult process. Advanced studies can be conducted using modern 3D systems. However, due to their high cost, usage of these 3D systems is still restricted to research environments. 2D systems offer simpler and more affordable solutions. Methods In this study, the gait of 40 volunteers walking on a treadmill was recorded in the sagittal plane, using a 2D motion capture system. The extracted joint angles data were used to create cyclograms. Sections of the cyclograms were used as inputs to artificial neural networks (ANNs), since they can represent the kinematic behavior of the lower body. This allowed for prediction of future states of the moving body. Results The results indicate that ANNs can predict the future states of the gait with high accuracy. Both single point and section predictions were successfully performed. Pearson’s correlation coefficient and matched-pairs t-test ensured that the results were statistically significant. Conclusion The combined use of ANNs and simple, accessible hardware is of great value in clinical practice. The use of cyclograms facilitates the analysis, as several gait characteristics can be easily recognized by their geometric shape. The predictive model presented in this paper facilitates generation of data that can be used in robotic locomotion therapy as a control signal or feedback element, aiding in the rehabilitation process of patients with motor dysfunction. The system proposes an interesting tool that can be explored to increase rehabilitation possibilities, providing better quality of life to patients.

title: Tobacco use and associated factors among students of a university of Criciúma (SC)

description: To investigate tobacco use and associated factors among college students at a university in southern Brazil in 2010, we conducted a cross-sectional study using self-reported questionnaires. The sample was divided into two main groups: the Health area and other courses The sample number in each group was divided according to the ratio of the total number of students. Students who composed the sample were selected from the first and last year of each course. Statistical analysis was performed with SPSS version 17.0(r). 584 students responded to questionnaires. The prevalence of smoking among students was 8.9%, 4.7% were smokers and 4.2% occasional smokers; 2.6% reported they were former smokers. The average age was 23.0 years (± 9.7), 62.3% were female. Among smokers 49% started smoking on their own and 27.4% under the influence of friends. We observed a significant association between smoking and alcohol use (OR 5.80; 95%CI 1.20-28.01), illicit drugs (OR 42.29; 95%CI 11.45-175.1) and the existence of other relatives who are smokers (OR 4.02; 95%CI 2.05-7.85).The prevalence of smoking found in this study was low. Smoking was significantly associated with student drugs users, consuming alcohol and to have a smoker in the family.

title: Ardras, Jejes and Minas, or slaves of "first reputation": African Politics, Slave Trade and identity in Eighteenth-Century Salvador, Brazil

description: Abstract: In 1715, a French observer commented that Salvador appeared to be a "New Guinea", due to the diversity of slave origins. However, in spite of this diversity, Salvador had a high concentration of enslaved Africans who shared similar origins. These slaves came primarily from the Bight of Benin, the second largest slaving region in Africa. The article aims to discuss the presence of gbe-speakers (ardras, minas and jejes, primarily) in Bahia in the eighteenth century. The work by Luís Nicolau Parés, A formação do candomblé, highlights the presence of Africans from the gbè-speaking area in eighteenth-century Bahia. Yet, it is necessary to investigate the Atlantic dynamics resulting in the deportation of gbe-speakers to the Americas on the light of new sources. In exploring the connections between the political events in the Bight of Benin and the Bahian slave trade, the article also seeks to discuss the numbers and origins of those exported to Bahia. I intend to combine quantitative analysis on the numbers of the transatlantic slave trade and the records in the probate and baptismal records in order to shed light on the lives of these West African groups in eighteenth-century Bahia.

title: Quantification of psychrotrophic bacteria and molecular identification of Pseudomonas fluorescens in refrigerated raw milk

description: ABSTRACT In this study, we investigated the contamination of refrigerated raw milk produced in the western region of Paraná, southern Brazil, with psychrotrophic microorganisms, aiming to assay the proteolytic activity of the isolates and to identify Pseudomonas fluorescens, the main proteolytic species associated with the spoilage of milk products. Raw milk samples from 50 dairy farms were submitted to the counting of psychrotrophic microorganisms, being the microbiota characterized by its mesophilic behavior and proteolytic capacity, besides molecular identification of P. fluorescens. Of the samples evaluated, 94% had psychrotrophic counts ranging from 3 to 7.1 log CFU mL-1, and 48.5% of these showed mesophilic behavior. Of the isolates, 48.0% had proteolytic activity in at least one evaluated temperature (21 and 30°C), and 39.3% had proteolytic activity in both temperatures. Among the 61 isolates submitted to molecular identification by polymerase chain reaction (PCR), 86.8% contained the expression of the 16S gene characteristic for P. fluorescens. In this study, we demonstrated that P. fluorescens is the most prevalent psychrotrophic bacteria species in raw refrigerated milk and their proteolytic ability poses high risks to the dairy industry.

title: Simulation of the mechanical process of gypsum cutting with picks

description: Abstract Several research works have been done to assess the effect of the cutting depth on the cutting forces when using picks. In this case, the cutting tests need im-portant equipment to cut rocks, to register the cutting force and to determine the cutting force value. The purpose of this research work is to simulate the laboratory rock cutting tests to determine the cutting force, using commercial software; and to compare the cutting force values to those obtained in the la-boratory. In the simulation, we took a gypsum rock sample as the specimen,. We simulated the separation of the rock chips from the specimen and the sub-sequent breakage into multiple fragments. In the simulations, a cutting pick was compared with a stationary rock sample. The simulations were conducted at a same constant velocity for different cutting depths. The simulations showed that the depth of cut has a significant effect on the cutting force, and the values of the cutting force in the simulation are very close to those obtained in the laboratory.

title: Genetic Variability in Natural Populations of Cassia grandis L. F.

description: ABSTRACT The design of strategies for genetic conservation requires knowledge of the ecologic and genetics aspects of the target species populations. This work aimed to characterize genetically natural populations of Cassia grandis L. F. using isozymes. Genetic diversity was analyzed by allele frequencies ( P ^ i j ) and the following diversity indexes: observed ( H ^ e ) and expected ( H ^ e )average heterozygosity, average number of alleles per locus ( A ^ ) and percentage of polymorphic loci ( P ^); and the genetic structure of populations by Wright's statistics. We estimated gene flow, population effective size and the minimum viable population in the short and long time. The observed results conclude that the studied populations of C. grandis are structured, which can be demonstrated by observation of rare and exclusive alleles, and high genetic diversity among them.

title: Persistence of malathion used in dengue control on household surfaces

description: ABSTRACT: Dengue is a viral infection transmitted by the mosquito Aedes aegypti. In Brazil, one of the insecticides used to control the mosquito is malathion, which can be diluted in vegetable oil (1:2 v/v). The purpose of this study was to understand the persistence of malathion on different surfaces and soil. Surfaces were contaminated by malathion and then washed with water and soap. The water used to clean the surfaces was extracted and analyzed by gas chromatography with an FID detector. Soil samples received malathion 14C-TG diluted in vegetable oil (1:2 v/v) and were analyzed zero, 3, 7, 18, 32, 60, 120, 240, and 360 days after the application in a liquid scintillation analyzer. Results showed a high persistence of malathion on porous surfaces. Moreover, it did not degrade in the soil for the first 120 days.
