title: Photographic views of railroads: recording public works in nineteenth-century Brazil

description: Abstract This article analyzes how railway engineering was connected to the production of photographs in mid-nineteenth-century Brazil. The hypothesis is that growing demands related to the execution of projects and new cartographic knowledge required more visual records, which was supplied and leveraged with the emergence of photographic techniques. Data was collected on photographic records of railroads taken in Brazil after the 1850s to analyze the characteristics of these images. This analysis was further extended in a series of photographs by Marc Ferrez, since this collection contains the most views of railways currently accessible, permitting the recognition of patterns in these images to identify them as “photographic project records.”

title: Review of the family Rivulidae (Cyprinodontiformes, Aplocheiloidei) and a molecular and morphological phylogeny of the annual fish genus Austrolebias Costa 1998

description: ABSTRACT The family Rivulidae is the fourth most diverse clade of Neotropical fishes. Together with some genera of the related African family Nothobranchiidae, many rivulids exhibit a characteristic annual life cycle, with diapausing eggs and delayed embryonic development, which allows them to survive in the challenging seasonal ponds that they inhabit. Rivulidae also includes two species known as the only the self-fertilizing vertebrates and some species with internal fertilization. The first goal of this article is to review the systematics of the family considering phylogenetic relationships and synapomorphies of subfamilial clades, thus unifying information that is dispersed throughout the literature. From this revision, it is clear that phylogenetic relationships within Rivulidae are poorly resolved, especially in one of the large clades that compose it, the subfamily Rivulinae, where conflicting hypotheses of relationships of non-annual and annual genera are evident. The second goal of this work is to present an updated phylogenetic hypothesis (based on mitochondrial, nuclear, and morphological information) for one of the most speciose genus of Rivulidae, Austrolebias. Our results confirm the monophyly of the genus and of some subgeneric clades already diagnosed, but propose new relationships among them and their species composition, particularly in the subgenus Acrolebias.

title: Thermogravimetric analysis for characterization of the pellets produced with different forest and agricultural residues

description: ABSTRACT: The pelleting of forest and agricultural materials, mainly because many residues from both industries can be used in this process, has been an alternative in obtaining added value products to energy generation. Thus, the aim of this study was to evaluate the energy quality of the pellets produced from forest and agricultural residues as raw materials and to verify the utility of the thermogravimetric analysis (TGA) and the differential thermogravimetric analysis (DTG) in characterizing the behavior of the pellets during the combustion process. Four residues were used: (1) Pinus spp. woodchips, (2) apple pruning residues, (3) aciculated dry branches of Araucaria angustifolia and (4) A. angustifolia empty-seeds. Chemical composition of the raw materials was determined and the physical and energetic properties of the pellets were analysed. Plus, the proximate analysis of the pellets was carried out. The samples were submitted to TGA with a heating rate of 20ºC min-1 from room temperature to 1000ºC, in a N2 atmosphere. The variation of chemical composition of each residue was determinant in the characterization of each stage of the thermal degradation. Stages and events of the degradation were closely linked to the chemical and energetic nature of the samples. Use of TGA to characterize the thermal degradation of the pellets produced with different forest and agricultural residues was demonstrated as an efficient technique to quantify and qualify the events that occurred in each stage of the combustion of these biofuels.

title: Phylogenetic relationships of Chanidae (Teleostei: Gonorynchiformes) as impacted by Dastilbe moraesi , from the Sanfranciscana basin, Early Cretaceous of Brazil

description: ABSTRACT Fossil gonorynchiform fishes range from the Lower Cretaceous to the early Miocene, and are represented by a few dozen living species. The order is currently divided into two major clades: Gonorynchoidei, which includes the families Gonorynchidae and Kneriidae, and Chanoidei, encompassing a single family, Chanidae, with a single recent species, the Indo-Pacific Chanos chanos, and several fossil taxa. Chanidae includes some poorly known taxa, such as Dastilbe moraesi, described from the Aptian (Lower Cretaceous) of the Areado Formation, Sanfranciscana basin, Brazil. This species is currently considered to be a junior synonym of the type species of its genus, Dastilbe crandalli, from Santana Formation, Aptian, northeastern Brazil. The analysis of abundant D. moraesi specimens revealed several new morphological features, many of which had previously been misinterpreted. Dastilbe moraesi was incorporated into a gonorynchiform character matrix as revised and modified for the Chanidae. We obtained a single most parsimonious tree in which D. moraesi is distinct and phylogenetically apart from D. crandalli. According our analysis, D. moraesi forms a sister pair with Chanos, a clade which is closely related to Tharrhias, all composing the tribe Chanini.

title: Evaluation of the micropropagation potential of curauá pineapple hybrids for fiber production

description: ABSTRACT Plant fiber is a renewable and biodegradable material that can be used effectively to reinforce various composites. Pineapple hybrids selected for their fiber quality are in the phase of agronomic validation in Brazil by the Embrapa Cassava and Fruits research unit. The selection of a hybrid for large-scale fiber production depends on obtaining a large number of seedlings. This study evaluated the morphogenetic response and propagation potential of eight hybrids of Ananas comosus var. erectifolius, for the purpose of producing high-quality seedlings on a large scale. Stem and crown buds were reduced and placed in MS nutritive medium supplemented with BAP at 0.5 mg L-1, NAA at 0.01 mg L-1 and Phytagel® at 2.5 g L-1. After 45 days, the number of oxidized, contaminated and surviving buds was determined. Swollen buds and plantlets were transferred to a multiplication medium containing MS sucrose, salts and vitamins. The propagation potential was evaluated based on the geometric growth rate among sub-cultures. The FIB-NEG hybrid presented the best results for the establishment phase (40.28%). The best propagative potential was obtained from crown buds with the highest values for FIB-EST (3.93), FIB-MIN (3.91) and FIB-BOY (3.91) hybrids.

title: Competitive interaction between commom black bean cultivars and Euphorbia heterophylla 1

description: ABSTRACT Weeds can interfere in the growth and development of bean plants if not properly managed, especially the wild poinsettia (Euphorbia heterophylla L.). This study aimed to evaluate the competitive ability of black bean cultivars coexisting with wild poinsettia. The experiment was conducted in a greenhouse, in a completely randomized design, with four replications. Each treatment consisted of one bean plant of the BRS Campeiro, IPR Uirapuru or SCS Predileto cultivars, living with 0, 1, 2, 3, 4 or 5 wild poinsettia plants, corresponding to populations of 0 plants m-2, 22 plants m-2, 44 plants m-2, 66 plants m-2, 88 plants m-2 and 110 plants m-2. Bean and wild poinsettia plants were assessed for stem diameter, leaf area, chlorophyll content, plant height and shoot dry mass. The bean cultivars behaved differently when cultivated with distinct wild poinsettia populations. The SCS Predileto cultivar showed a higher competitive ability against the wild poinsettia than the BRS Campeiro and IPR Uirapuru, what can be verified by the reduction of leaf area and dry mass of the weed. On average, at a density of 110 plants m-2, the wild poinsettia reduces in approximately 32 % the leaf area and 50 % the dry mass of the bean plants.

title: PROFILE AND APPROPRIATE USE OF ANTIBIOTICS AMONG CHILDREN IN A GENERAL HOSPITAL IN SOUTHERN BRAZIL

description: ABSTRACT Objective: To examine the profile and appropriate use of antibiotics among hospitalized children. Methods: A cross-sectional study was conducted with children who had taken antibiotics during hospitalization in a private philanthropic hospital in Southern Brazil, from January to December 2015. The data were obtained by reviewing medical records, encompassing demographic data (age, gender, ethnicity, and body weight) and clinical data (causes of hospitalization, use of antibiotics, and clinical outcome). Descriptive statistics was used to present the data. Results: Of the 318 participants included in the study, 61.3% were male patients. The age range varied between 2 and 11 years, with mean age of 5.8±2.9 years. The prevalence of antibiotics was 24.4% out of the 1,346 hospitalized children. Median hospital stay was four days. The main cause of hospitalization was clinical instability, and the most commonly prescribed antibiotics was Cefazolin, mostly administered intravenously. Regarding the administration of antibiotics, 62.2% were adequately prescribed, even though underdose was 11.7%, and overdose was 14.6% in the studied patients. Antibiotic administration intervals were characterized as long in 8% of cases, and short in 3.5% of cases. Conclusions: Although the prevalence of antibiotics among hospitalized children was not that high, a considerable part of the sample presented inadequacy regarding the dosage and range of use. These data raise concerns about bacterial resistance and adverse reactions.

title: Experiment to model the accommodation of the human eye

description: Abstract We build a simple and inexpensive system that simulates the process of human accommodation. We used a ball lens, made of a male latex condom filled with water, and two diode lasers that can change from collimated to divergent beams, adjusting their rotatory supports. The device is suitable for secondary classes in optics. Students have calculated and measured the focal length of the ball lens (fmeasured /fcalculated = 0.94 ± 0.06) and have studied how human vision shifts from the relaxed condition to the condition of visualizing nearby objects, by squeezing the lens (simulating the crystalline work). Other details of human vision accommodation are also discussed.
