title: ANTEGRADE X RETROGRADE NAILING IN FEMORAL FRACTURES: A STUDY ON CONSOLIDATION AND INFECTION

description: ABSTRACT Objective: Osteosynthesis with intramedullary nailing is considered the method of choice to treat diaphyseal femur fractures in adults. The objective of this retrospective study was to evaluate the bone healing time and incidence of infection in patients with diaphyseal femur fractures treated surgically with retrograde and antegrade intramedullary nailing. Methods: The medical records of 123 patients from two university hospitals dated 2011-2013 were evaluated, with 126 diaphyseal femur fractures having been found. The most frequent treatment was antegrade intramedullary nailing (51%), of which 38% involved reaming (n=25). Results: We found evidence of 92% healed fractures at 12 months postoperatively. Complications included chronic osteomyelitis in one patient and femoral neck fracture in another patient, both after reamed antegrade nailing. Pyoarthritis of the knee associated with osteomyelitis affected two patients after reamed retrograde nailing and one patient after unreamed retrograde nailing. Conclusion: We did not observe a significant difference in bone healing rates with the use of reamed or unreamed antegrade or retrograde nailing. Complications included the presence of infection with an incidence similar to that reported in the literature, and of particular significance, unrelated to the type of approach. Level of evidence III, Retrospective comparative study.

title: Analysis of digital teaching materials provided from an open website: the case of the Canary Islands

description: ABSTRACT This article provides the results of the analysis of a sample of the digital contents or teaching materials for Primary Education existing in a website called Eco Escuela 2.0 promoted by the educational administration (Educational Counselling of the Canary Islands Government), characterized by the free access and use for the teachers. The main purpose is to perform a material analysis oriented towards the end of the Primary Education in different subjects. The methodology used in the study consisted in content analysis. To this end, an instrument-guide for the analysis of the sample has been prepared. The results of the investigation detect activities that aim to favor the resolution of problems, experimentation or simulation. Its design is acceptable, although qualitatively improvable: some are developed by teachers, thus they lack of the visual appeal of commercial materials. Most are closed and non-modifiable, created for specific contents and purposes, although they are adapted to different learning paces. In general, they do not provide final activities and some of them finish with the accomplishment of deliverable group tasks, elaboration of materials, discussion of ideas or task presentation. The cultural or functional diversity of gender is not present in these materials and although the access is good, optimization must be improved for all types of mobile device screens.

title: Use of 2,4-D in Mixture with Ethephon and Calcium Carbide in Pineapple Crop

description: ABSTRACT: The 2-Chloroethylphosphonic acid (ethephon) and calcium carbide are used to induce and synchronize the flowering of pineapple crop. Some farmers have used the 2,4-D herbicide in combination with these flowering inducers. This practice is based on the hypothesis that 2,4-D would act as a growth regulator, increasing fruit size and weight. The objectives of this work was to verify if the use of 2,4-D, associated to calcium carbide or ethephon, influences the productivity and quality of the pineapple fruits and, also if the use of this herbicide leaves residues in the fruits. For this, two field experiments were carried out in two different farms. The treatments consisted of the application of ethephon and calcium carbide, alone, and in a mixture with two, four and six drops of 2,4-D in the center of the leaflet of the pineapple cv. “Pérola” at 10 months after planting. The use of 2,4-D mixed with calcium carbide or ethephon, regardless of the dose and culture environment, did not influence the size, weight, total soluble solids content, density and pH of the pineapple fruits. However, depending on the growing environment, ethephon + 2,4-D mixtures did not influence or reduce flowering and crop yield. No 2,4-D residues were found in the fruit pulp of pineapple. It was concluded that the use of 2,4-D as a growth regulator of pineapple under the conditions evaluated does not incorporate qualitative or quantitative benefits to the productive system of this crop. In addition, no 2,4-D residues were found in the fruit pulp of pineapple.

title: SPRAY RETENTION ON COFFEE LEAVES ASSOCIATED WITH TYPE AND CONCENTRATION OF ADJUVANTS

description: ABSTRACT Agricultural spray adjuvants (ASA) are widely used in pesticide applications to enhance the performance of pesticides. The aim of this research was to investigate the effects of ASA on static surface tension (SST) and foliar spray retention on coffee leaves. The SST of ASA at different concentrations was determined by the drop weight method. Spray retention on adaxial and abaxial coffee leaf surfaces was performed using a micro-sprayer at solution concentrations of 0, 0.01, 0.1, 0.5, and 1.0% v v−1. The ASA assessed were: polyether-polymethylsiloxane-copolymer (PPC); Nonylphenol ethoxylate; nonyl polyethylene glycol ether; mineral oil; nonylphenoxy polyethoxy ethanol; carboxyl copolymer of styrene and butadiene; primary aliphatic oxyalkylated alcohol plus carboxyl copolymer of styrene and butadiene; and soyal phospholipids and propionic acid. All ASA reduced the SST of the aqueous solutions. PPC provided the best performance in decreasing SST, reaching values below 20 mN m−1 at a concentration of 0.05% v v−1. Spray retention on leaves was influenced by adjuvant type as well as concentration. A very strong positive correlation between SST and spray retention on coffee leaves was observed. Decreasing the SST of the solution provided a reduction of spray retention when spraying was performed until run-off point.

title: Influence of ZnO on the properties of elastomeric compositions and their leached extract

description: Abstract The reductionin zinc oxide (ZnO) content in elastomeric compositions has become a subject due to the deleterious effect of zinc ions on aquatic organisms. The purpose of this study was to develop elastomeric compositions containing 0, 1, 3 and 5 phr of ZnO aiming at assessing the influence of the different contents on the rheometric, mechanical and thermal properties. The release of the zinc (Zn) content by leaching, at each step of the production and after the ageing was also assessed. All ZnO-containing compounds had similar rheometric, thermal and mechanical properties. Also, during and after exposure to accelerated ageing the released contents were similar for all compositions regarding the residual ZnO percent. In conclusion, the utilization of the 3 phr ZnO content is viable for the replacement of the usual amount employed.

title: Influence of water absorption on glass fibre reinforced IPN composite pipes

description: Abstract Glass fibre reinforced composite pipes were fabricated by using an IPN blend of 0%, 10%, 20%, 30%, 40%, 50% PU prepolymer (Polyurethane) with VER(Vinylester) resin. The prepared IPN (Interpenetrating polymer networks) composite pipes were subjected to boiling water immersion tests in order to study the effect of moisture absorption characteristics. The Burst strength and Hoop strength of water immersed specimens were evaluated (3, 6, 9, 12 months) and compared along with dry composite specimens. It was found that, percentage of moisture uptake was significantly reduced with increase in PU loading into the IPN system as well the Burst strength and Hoop strength of the specimens were found to be diminishing with raise in percentage of moisture uptake and raise in temperature; contrarily, the addition of PU significantly reduced the moisture intake, in addition to that the PU added IPN pipe offers better mechanical strength while compared with neat Vinylester pipes.

title: Effects of miniemulsion operation conditions on the immobilization of BSA onto PMMA nanoparticles

description: Abstract Polymer nanoparticles have been widely used in many biomedical applications, constituting a major incentive for immobilization of proteins. Poly(methyl methacrylate) nanoparticles were synthesized through miniemulsion polymerizations and used as supports for bovine serum albumin immobilization. Particularly, the effects of surfactant type (anionic sodium dodecyl sulfate and cationic cetyl trimethyl ammonium bromide) surfactant concentration and monomer holdup on some of the final nanoparticle properties (particle sizes, zeta potential and protein load) were characterized with help of statistical experimental designs for the first time. Results showed that the characteristics of the surfactant controlled the BSA adsorption efficiency, with enhanced rates of adsorption on the anionic particle surfaces, showing that the surfactant exerts fundamental effect on functionalization of emulsified polymer particles, which must be explicitly acknowledged in studies of polymer particle functionalization with proteins. Finally, BSA adsorption was shown to follow a multilayer process, given the better fitting with the Freundlich model.

title: Extension of the geographic distribution of Plecturocebus baptista (Pitheciidae, Primates) and a possible hybrid zone with Plecturocebus hoffmannsi: evolutionary and conservation implications

description: ABSTRACT Titi monkeys (family Pitheciidae) are Neotropical primates highly diversified in morphology, ecology and genetics, with a wide geographic distribution, including the Amazon, Atlantic Forest, Cerrado, Pantanal and Caatinga. This diversity, together with knowledge gaps, generates uncertainties in titi monkey taxonomy and distribution. An example is Plecturocebus baptista, with only 14 occurrence records and an ill-defined distribution based on untested geographical barriers. Here, we report the occurrence of this species at a new locality outside its known range, across the Paraná-Urariá River, which was considered a distributional limit for the species. The new record implies an overlap of P. baptista with the range of P. hoffmannsi. We document the sighting of an apparent hybrid animal. Our observations suggest that i) the distribution of P. baptista needs to be reviewed, and ii) the evolutionary relationships between P. baptista and P. hoffmannsi may be more complex than previously assumed. Since both species share contiguous areas of potential hybridization, we question whether the two species arose via allopatric speciation.

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: Biometric relationships between body size and otolith size in 15 demersal marine fish species from the northern Brazilian coast

description: ABSTRACT The relationships between fish size and sagitta otolith measurements were calculated for the first time for 15 species belonging to six families from the northern Brazilian coast. A total of 220 fish were sampled from the bycatch landed by the bottom-trawl industrial shrimp-fishing fleet between August and September 2016. All species had strong relationships between otolith measurements and fish total length with the coefficient of determination (r 2) ranging between 0.71 and 0.99. The variable most strongly related to fish total length was found to be the sagittal otolith length (OL) with 98% of the variability. These relationships are a useful tool to estimate length and mass of preyed fish from otoliths found in stomach contents of marine predators.
