title: Hierarchical Facility Location Model for allocating cancer treatment units in interior of Rio de Janeiro

description: Abstract Paper aims This work aims at proposing a mathematical model for allocation of oncological treatment units of SUS. Originality A model of the same architecture was not found in the literature for the delimited problem. Research method The mathematical models of location in the literature were reviewed and based the choice by the two-level hierarchical pq-median model with additional constraints of maximum distance and vertices eligibility, which was implemented in the CPLEX optimization software. Main findings Satisfactory results with homogeneous networks, centralized facilities in their service area and shorter distance traveled by users indicate the efficiency of the model in determining the optimum location given the number of facilities to be allocated. Implications for theory and practice The model proved to be an efficient tool to assist health managers in their decision-making about the network of facilities, not just oncological, but of any nature and many others public sectors.

title: R&D spillovers from international student flows: a brics analysis

description: Abstract Paper aims to analyze the international flow of students - both from developed and underdeveloped countries - and to observe their significance for the productivity gains of the country of origin of these students. Originality The main contributions to the literature are the understanding of how student flows affect countries' economic growth, as well as to verify the systematic differences between the contribution of international student flows to economic growth between developed and underdeveloped countries. Research method This empirical study performed using a data set of 87 countries, during 2001-2012 yields results that are in accordance with previous literature, supporting the hypothesis of international student flows as a significant channel of R&D spillovers from developed countries. The paper used econometric models already tested by previous studies. Main findings The results show that BRICS countries may benefit more than other countries from such internationalization initiatives. Implications for theory and practice The mobility of international students is currently an important political issue in the world. These formal or informal links between agents from diverse countries result in an exchange of ideas, experiences and knowledge potentially generating new business opportunities for developing economies.

title: Molecular detection of Ehrlichia canis and Anaplasma platys in dogs from municipality of Belém, State of Pará, Brazil

description: ABSTRACT: The occurrence of diseases transmitted by ticks in dogs is very frequent in Brazil, among these diseases we can highlight the ehrlichiosis and anaplasmosis, which are caused by Ehrlichia canis and Anaplasma platys, respectively. The objective of this study was to survey the occurrence of these pathogens in blood samples from domiciled and stray dogs from the city of Belém, Pará. Two hundred and seventy six dogs were sampled for convenience, and the DNA extracted from the blood of these animals was submitted to nested-PCR for research of E. canis and A. platys. E. canis DNA was detected in 39.4% (109/276) and A. platys DNA in 23.1% (64/276) of the samples, there was a statistically significant difference between the frequency of these agents (P&lt;0.0001), and there was coinfection in 13.4% (37/276) of animals. The frequency of detection of these parasites was higher in stray dogs than in those domiciled for both E. canis (OR=2.84) and A. platys (OR=10.5). Considering the results, it was possible to conclude that E. canis and A. platys are present in the studied population, with stray dogs being more affected by these parasites.

title: Synthesis and characterization of microalgae fatty acids or Aloe vera oil microcapsules

description: Abstract It’s proposed a single methodology for the encapsulation of Aloe vera oil or microalgae fatty acids using the complex coacervation process between gelatin and gum arabic. Although a very recurrent method, it is not trivial to establish a single coacervation methodology to encapsulate different compounds. The optimal synthesis conditions, that resulted in the best yield and encapsulation efficiency, are 1:1 (m/m) wall-to-core ratio, a temperature of 40°C and agitation speed of 10,000 rpm. Optical microscopy analysis revealed that the microcapsules are spherical, have average diameters of 112 μm (A. vera) and 118 μm (microalgae) and do not form agglomerates. The microcapsules were characterized by the osmotic pressure at which they ruptured, allowing the calculation of their mechanical resistance, which resulted in 392 MPa (A. vera) and 425 MPa (microalgae). The presented optimized methodology to encapsulate both compounds aims to contribute to their efficient and rational use, especially in cosmeceutical applications.

title: Mycorrhization and grafting improve growth in the tomato and reduce the population of Nacobbus aberrans

description: ABSTRACT Inoculation with mycorrhizal fungi and the use of rootstock that is tolerant or resistant to nematodes are two strategies that allow the nematode to be controlled, and plants to coexist with the pathogen. However, the two techniques have always been tested in isolation, when their positive effects are less compared to when they are able to act together. In the present work, two rootstocks combined with the mycorrhizal fungus Rhizophagus intraradices were compared, with the aim of evaluating their behaviour on the growth of tomato plants in soils infested with N. aberrans, the false root-knot nematode. The experiment was set up in a completely randomised design with ten replications, in a 3 x 2 x 2 factorial scheme. The treatments consisted of a combination of three factors: a) plant composition: two rootstocks (Solanum lycopersicum var. cerasiform 'Carolina' and S. lycopersicum 'Maxifort'), onto which the 'Santa Clara' tomato (S. lycopersicum) was grafted, and a non-grafted plant, considered the control, which was the same cultivar as the graft; b) mycorrhization: mycorrhizal or non-mycorrhizal roots; c) a substrate infested or not infested with N. aberrans. The plants grafted onto 'Maxifort' showed significantly greater growth for shoot dry weight, root fresh weight and stem diameter. The rootstock under test had a lower pathogen reproductive factor than did the ungrafted plant. Mycorrhization contributed to a reduction in the number of days until flowering, and a reduction in the final population of N. aberrans for the three plant compositions under test.

title: Syrian and Lebanese in Western São Paulo

description: Abstract The article seeks to explore the conditions and distinctive characteristics of the socioeconomic insertion of Syrians and Lebanese in the interior of São Paulo between the 1880s and 1950s. From the difficult beginning as peddlers with a distant culture, Syrians and Lebanese managed to establish themselves as merchants, seizing the opportunities that their networks (of relatives and of countrymen) and the expanding coffee economy offered, establishing themselves mainly in the sectors of clothing, linen and fabrics, cattle and cereals. Taking as main source a series of works in which the Syrian and Lebanese immigrants are portrayed in the interior, the article also indicates the main regions of west of São Paulo where the group mainly concentrated, and discusses trajectories which illustrate some of the possibilities of mobility, formation of leadership, the way religious practices have been transformed and the marked mobility - as doctors and politicians - achieved by strata of the first generation born in Brazil.

title: TRANSFER OF THE RADIAL NERVE BRANCHES FOR THE TREATMENT OF THE ANTERIOR INTEROSSEOUS NERVE LESION: AN ANATOMICAL STUDY

description: ABSTRACT Objective: This anatomical study aimed to analyze the possibility of transferring the radial nerve branches destined to the brachioradialis (BR), extensor carpi radialis longus (ECRL), extensor carpi radialis brevis (ECRB), and supinator (SM) muscles to innervate the AIN. Methods: Ten limbs from five male cadavers were prepared by intra-arterial injection of a solution of 10% glycerol and formalin. Results: The presence of only one branch to the BR muscle was noted in 7 limbs and two branches were noted in three limbs. In two members of a common trunk with branch to the ECRL. In eight cases, we identified one branch for the ERLC and two branches in two cases. We identified only one branch for the ECRB, while in six limbs, two branches were noted, penetrating the muscular body at two different points. We identified at least two branches innervating the supinator muscle. The AIN was detached from the median nerve distal to the intercondylar line of the humerus. In seven limbs, it originated from the nervous fascicles of the posterior region of the median nerve and from the posterolateral fascicles in three limbs. The flexor pollicis longus and flexor digitorum profundus muscles received more than one branch of the AIN in all limbs. Conclusion: The radial nerve branches for the ECRL, ECRB, and supinator muscles can be transferred directly to the AIN or to one of its branches after intraneural dissection, without tension even in elbow movements. Level of Evidence IV; Case series.

title: Economic Injury Level of Canjiqueira in Native Pastures in Pantanal of Nhecolândia

description: ABSTRACT: Pantanal plain has large extensions of land formed by many types of landscapes suitable to extensive livestock system. Open grasslands and lowlands are formed by forage such as grasses and forbs widely consumed by cattle. However, climatic and human factors can promote the dissemination of invasive shrub species such as canjiqueira (Byrsonima cydoniifolia A. Juss) making it necessary, in many cases, the human intervention to control the invasion. The present work had as objective to determine the economic threshold level to control canjiqueira through two methods: tractor driven blade and link chains pulled by tractor in different invasion levels plants per hectare. Economic Threshold proved to be a tool for efficient and effective management for making decisions of when and how to do the control of canjiqueira in natural pastures of Pantanal of Nhecolândia.

title: Goosegrass: Morphophysiological Characterization Under Water Excess Conditions

description: ABSTRACT: Eleusine indica (L.) Gaertn. (goosegrass) is a grass species that has global prominence as a weed in areas typical of the soybean crop. However, its dispersion in recent years has been reported expressively for areas of poorly drained soil, in which irrigated rice is cultivated (lowlands). Little is known on its behavior and biology in this different ecosystem. This study aimed to evaluate if Eleusine indica can survive and withstand flooding. The experimental design was a completely randomized (two-way), in which two E. indica biotypes, one from the uplands (without flooding) and the other from the lowlands (with flooding), were submitted to three soil water conditions: 50 and 100% water retention capacity and soil under water depth. Photosynthetic and gas exchange parameters (photosynthetic rate, stomatal conductance, intercellular CO2 concentration, transpiration, water use efficiency, and assimilation rate by Rubisco) were determined. Morphological diversity of biotypes was evaluated through descriptors. The existence of typical lowland biotype could not be characterized. However, both biotypes were able to survive, develop, and generate seeds in a flooded environment in the irrigated rice system.

title: First report of Diplostomidae metacercariae (Trematoda: Digenea) in African catfish Clarias gariepinus (Siluriformes: Clariidae) in Brazil

description: Abstract Clarias gariepinus is a fish from North of South Africa and was later introduced in several countries, including Brazil. The present study aimed to describe the first report of Diplostomidae metacercariae in C. gariepinus in Brazil. For this, 30 C. gariepinus were captured in a lake in the city of Campos dos Goytacazes, RJ, Brazil. Fishes were euthanized using freezing and necropsied for collection of parasites. The organs were dissected and analyzed for the presence of parasites that were processed for light and scanning electron microscopy. Trematodes were stained with Semichon’s Carmine and Gomori’s Trichrome, observed and schematized under a light microscope with image analysis software. A total of 190 trematodes were collected from the gills, suprabranchial organs, heart, stomach, intestinal mesentery, liver and body cavity of the fish. The parasites had a foliaceous body divided by a discrete constriction, without genital primordia, and a holdfast organ present at the posterior region, typical of metacercariae of the family Diplostomidae. It was classified as the 'Diplostomulum' morphotype, based on the morphology of the reserve bladder structure. This is the first report of the metacercariae of Diplostomidae parasitizing C. gariepinus in the Americas. This fish acts as an intermediate or paratenic host of this digenean in Brazil.
