title: Validation of the Brazilian version of WHODAS 2.0 in patients on hemodialysis therapy

description: Abstract Introduction: Chronic kidney disease and hemodialysis normally have an impact on the functioning. Objective: To validate the Brazilian version of the World Health Organization Disability Assessment Schedule 2.0 in individuals with chronic kidney disease on hemodialysis treatment. Methods: The 36-item version was applied to interview 51 individuals with chronic kidney disease undergoing dialysis treatment. To ascertain the instrument’s applicability, its internal consistency and test-retest stability were studied. To check the validity, a convergent/divergent analysis was performed. Results: The participants answered the questions on the main instrument at two timepoints and on the World Health Organization Quality of Life Abbreviated instrument and the Kidney Disease Quality of Life - Short FormTM 1.3 once each. Cronbach’s α coefficient was appropriate in all domains except the “Getting along” domain. The test-retest coefficients were above the recommended value (&gt; 0.70). Convergent and divergent validity analysis also showed consistent results by correlation coefficient assessment. Conclusion: The instrument is valid and reliable. This study supports the use of the questionnaire by presenting its appropriate psychometric properties. We suggest that some care should be taken specifically in the sexual questions of the “Getting along” domain.

title: Capitulum and floret phenology in Baccharis aliena (Asteraceae, Astereae)

description: Abstract Inflorescence and floral phenological studies are a source of valuable knowledge to interpret reproductive mechanisms and phylogenetic hypothesis in plants. We analyzed the morphology and functionality floret stages that are present in pistillate homogamous and functionally staminate heterogamous capitula of the dioecious species Baccharis aliena. Phenological monitoring of both types of capitula was carried out in cultivated plants of B. aliena. Floret phenological stages were defined in homogamous and heterogamous capitula by morphometric analyses, from pre-anthesis until senescence symptoms first appeared. Florets of homogamous and heterogamous capitula presented visual anthesis before functional anthesis was achieved and this feature was transferred to the phenology of capitulum. Anthesis of successive series occurs centripetally during a period of 21 days in the homogamous capitula and 20 days in the heterogamous capitula. The timing and length of heterogamous and homogamous capitula is tightly coordinated and almost identical, a feature that ensures floret interaction between plants and pollinator activities. Understanding of breeding systems in the Astereae subtribe Baccharidinae will most assuredly provide helpful insights towards a better understanding of the evolution of this highly successful group.

title: ASSESSMENT OF ACADEMIC TRAINING AND JOB PLACEMENT IN GRADUATES FROM TEACHING IN BASIC EDUCATION PROGRAMS IN CHILE

description: ABSTRACT: The expansion of access to higher education represented an advancement for the integration of traditionally excluded groups in Chile. However, expanding access is insufficient to ensure the equity of the higher education system. Under this premise, the article seeks to investigate aspects of academic training and employment from the perception of graduates, considering that these dimensions reflect relevant aspects of the degree of equity that could be evidencing the Chilean system. This exploratory study focused on graduates of the Teaching for Basic Education career of three universities with different levels of selectivity of their students. We conclude that there is no evidence that the degree of selectivity, as well as the characteristics and attributes of the academic training received by the graduates of different universities, are perceived as determining factors for the job placement of graduates.

title: THE DEGREE IN HISTORY TEACHING AND THE 10.639/03 STATUTE - TRAINING PATHS TO DEAL WITH DIFFERENCE?

description: ABSTRACT: The article deals with the formation of History teachers over the last fifteen years, considering the legislation that reformulates the perspective of Brazilian History in Basic Education’s curricula. National guidelines for education in ethnic-racial relations bring about changes in the training paths, which develops substantive changes in the model usually adopted for teacher formation in History. Therefore, the article analyzes the impact of such changes, parting from the curricular paths of courses offered by federal universities in ten units of the federation. From the consideration of such trajectories, we intend to analyze the space destined for ethnic-racial relations formation and to deal with difference. We argue that the existing gaps related to the implementation of the basic statute are due to the way in which teacher formation is conceived and assumed in the curriculum paths studied.

title: Production of Ba2AlNbO6 Ceramics and Study of their Stability in Crude Petroleum for the Conservation of Metallic Sensing Elements Used in Petroleum Extraction

description: In the present work niobium based complex cubic perovskite oxide Ba2AlNbO6 ceramics were produced, characterized and their stability in crude petroleum environment was studied for inert ceramic embedding used in petroleum extraction. Ba2AlNbO6 ceramic powder was prepared by means of thermo-mechanical processing. Structural characteristics of calcined material were investigated by powder X - ray diffractometry, which presented a single phase complex cubic perovskite structure with lattice parameter a = 8.3418 Å. Compacted Ba2AlNbO6 ceramics were sintered at 1150ºC during 72 hours in ambient atmosphere. The microstructure of the sintered ceramics was studied by scanning electron microscopy and mechanical behavior was studied by Vicker's micro-hardness testing. The sintered ceramics were submerged in crude petroleum for 60 days. The ceramics were taken out from petroleum periodically and subjected to structural, microstructural and mechanical characterizations. The results showed that the ceramics submerged in crude petroleum did not suffer any change at any stage of submersion. These characteristics make this material suitable for inert ceramic embedding for sensors used in petroleum extraction.

title: TEACHING PORTUGUESE IN BRAZIL: LINGUISTIC DISTRIBUTION INEQUALITIES

description: ABSTRACT: Proposals for the renewal of the theoretical and methodological bases of Portuguese language teaching, in Brazil, took place in the second half of the twentieth century, in response to the linguistic diversity resulting from the arrival to school of social groups that historically did not have access to formal schooling. Since then, the country’s urbanization process has been consolidated, and the distribution of elementary education reaches almost all students in the school age. In the present context, linguistic conflicts in school are no longer supported by variables associated with the differences between rural and urban, or in a dichotomic opposition of oral culture to literate culture. In this work, based on the most recent studies about the linguistic distribution in Brazil, conceptions of Portuguese language teaching are revisited, observing the ruptures, dispersions, setbacks and inequalities that have been reproduced historically in this country.

title: Physiological parameters of F1 Holstein X Zebu cows raised in environments with and without shading

description: ABSTRACT The objective of this study was to characterize the effect of microclimate provided by two distinct environments on the physiological responses of F1 HxZ cows lactating during the summer, where 34 cows were evaluated originating from 4 different genetic groups F1 HxZ. During the trial period, daily measurements of environmental variables were determined: dry bulb temperature, relative humidity and black globe temperature, to calculate the BGT values. The physiological parameters respiratory rate, heart rate, body surface temperature, rectal temperature, and sweat rate were obtained at 07:00 and 14:00h. Weighing of milk was done weekly. The F1 animals evaluated did not present physiological changes, nor was there a reduction in milk production as a function of breeding environments. The BGT reached levels considered stressful (87.7), but the breeding environments provided no stress or reduced production of animals.

title: A comparative study of phytoconstituents and antibacterial activity of in vitro derived materials of four Passiflora species

description: Abstract Passiflora species are well known for their common use in popular medicine for the treatment of several diseases, such as insomnia, anxiety, and hysteria, in addition to their anti-inflammatory, antioxidant, analgesic and antibacterial potential. However, few data about the chemical composition and the medicinal potential of in vitro derived materials are available. Therefore, the goal of this work was to compare, for the first time, the phytoconstituents of in vitro derived materials of four Passiflora species, and evaluate the antibacterial potential of their extracts against 20 Gram-positive and negative strains. Chromatographic analysis indicated the presence of saponins in roots extracts from all studied species, whereas leaf extracts presented both saponins and flavonoids. Extracts from leaves and roots of P. alata and P. foetida exhibited a selective inhibitory activity against B. thuringiensis and S. pyogenes, which might be related to the presence of a high concentration of secondary metabolites, including flavonoids and saponins.

title: Production and performance of sugarcane seeds (caryopses) from different hybridizations involving RB92579

description: Abstract A major challenge in sugarcane breeding program is the obtaining of enough number of seeds (caryopses) for the development of new improved cultivars. Genotypes differ in their function as pollen recipient and pollen donor, which also affect the seed performance. Thus, the aim of this study was to verify the production and performance of sugarcane seeds from different hybridizations involving RB92579 as pollen recipient and pollen donor. Twelve bi-parental crossings were carried out involving RB92579 and other different genotypes randomly chosen. Seed production potential was evaluated by percentage of fertile spikelets and caryopsis fresh weight. The seed physiological potential was determined by evaluating germination and vigor (index of germination rate, number of normal seedlings per gram of fuzz, and seedling dry weight). The results showed better performance for RB92579 as pollen donor for all characteristics studied. Therefore, RB92579 sugarcane cultivar should be used as pollen donor during hybridizations, condition that permits a greater production and physiological performance of seeds for the sugarcane breeding programs.

title: New data on the Late Cretaceous lizard Dicothodon bajaensis (Squamata, Borioteiioidea) from Baja California, Mexico reveals an unusual tooth replacement pattern in squamates

description: Abstract Borioteiioids comprise an extinct family of squamates that inhabited the Northern Hemisphere during the Cretaceous and were characterized by varying patterns of tooth replacement and dental morphology. Understanding the evolution of these tooth replacement patterns has, however, been largely hampered by an extremely fragmentary fossil record. Here we present new information on Dicothodon bajaensisfrom the Campanian of Baja California (Mexico), so far known only from isolated teeth and jaw fragments. Among abundant new materials there are ten maxillae and five dentaries belonging to distinct ontogenetic stages. Whereas juveniles display active tooth replacement, older specimens show no evidence of replacement. Dicothodon bajaensis is therefore inferred to have had arrested tooth replacement later in ontogeny. This provides the first evidence of cessation of tooth replacement during late ontogeny in lizards (living or extinct). This replacement type is also an evolutionary intermediate between the typical lizard replacement pattern, observed in some borioteiioids (e.g., Bicuspidon) and the complete absence of tooth replacement since early ontogeny as observed in other borioteiioids (e.g., Polyglyphanodon).
