title: Evaluation of traumatic brain injury patients with signs of alcohol intoxication.

description: ABSTRACT Objetive: to evaluate the influence of alcohol intoxication in the time to perform head computed tomography and tomographic findings in traumatic brain injury patients. Methods: a retrospective study of 183 traumatic brain injury patients, divided into two groups: 90 alcoholics and 93 non-alcoholics. Time interval from patient’s arrival at emergency room to tomography was calculated for comparison between the groups, and tomographic findings were analyzed. Results: in the alcoholic group, the percentage of male patients was higher, the predominant age was between 31 and 40 years, aggression was the most frequent trauma mechanism, and these patients showed lower values on the Glasgow coma scale. It was observed that there was no statistical difference between the two groups regarding the time interval for tomography execution, as well as regarding the tomographic findings. In addition, in the alcoholic patients, when the Glasgow coma scale values were correlated with the time interval, there was no difference from scores 13 to 15 (mild traumatic brain injury) and those equal to or inferior than 12 (moderate and severe traumatic brain injury). Conclusion: signs of alcoholic intoxication did not influence the time interval for tomography execution. Patients under alcohol influence showed lower scores on the Glasgow coma scale due to the direct effect of alcohol and not due to a higher prevalence of tomographic findings.

title: Eustrongylides sp. (Nematoda, Dioctophymatoidea) parasitizing Hoplias malabaricus (Actinopterygii: Erythrinidae) collected from the state of Rio de Janeiro, Brazil

description: Abstract Hoplias malabaricus (Characiformes, Erythrinidae), trahira, is a neotropical freshwater fish of economic and public health significance. A total of 45 specimens of H. malabaricus commercialized in the municipality of Magé, state of Rio de Janeiro, Brazil, were acquired between April 2016 and April 2018 to investigate the presence of nematode larvae. Twenty of the fish were found parasitized by 347 fourth-stage nematode larvae identified taxonomically as Eustrongylides sp. using morphological, morphometric and molecular data. The parasitic indices were: prevalence 44.44%, mean intensity 17.35, mean abundance 7.71, and range of infection 2-40. Infection sites were musculature, mesentery, abdominal cavity, and serosa of intestine, stomach and liver. This is the first report of Eustrongylides sp. larvae parasitizing H. malabaricus in the state of Rio de Janeiro.

title: Physiological responses of lima bean subjected to salt and water stresses

description: ABSTRACT Under water deficit and/or salt stress conditions, crops suffer from several physiological disturbances, which lead to the reduction in growth and, consequently, decreases in their yields. Thus, the objective of this study was to evaluate the physiological responses of lima bean, cultivar Espírito Santo, under different irrigation water salinity associated to two water regimes. The experiment was carried out in the experimental area of the Universidade Federal do Ceará, Brazil, from September to November 2017, and it was carried out in pots in full sun, under a completely randomized design in split plots, where water salinities (1.1, 2.1, 3.1, 4.1 and 5.1 dS m-1) were considered as the plots, and the treatments of water regime (50 and 100% of the reference evapotranspiration - ETo) were considered as the subplots. At 45 days after sowing, leaf gas exchanges and relative index of total chlorophyll (SPAD index) were evaluated. In general, the increase of salt concentration in irrigation water causes reductions in the physiological responses of lima beans. Under a water regime of 50% ETo, the instantaneous and intrinsic water use efficiency is higher.

title: Integrated tick control on a farm with the presence of capybaras in a Brazilian spotted fever endemic region

description: Abstract Ticks of the Amblyomma cajennense complex present high infestation rates. These ticks transmit the bacterium Rickettsia rickettsii, which causes Brazilian Spotted Fever. For this reason, an integrated tick control system was adopted on a farm in the municipality of Itu, state of São Paulo. On this farm, which borders the Tietê river, domestic animals are in contact with populations of capybaras. Six locations were monitored and evaluated between the years of 2015 and 2017. During this work 1271 nymphs and adult ticks were caught, all of them from the Amblyomma sculptum species, except for a single individual from the Amblyomma dubitatum species. The integrated tick management reduced the overall infestation levels to zero. Adult tick population dropped in the first year of the study, while larvae population dropped in the second year. Nymph population dropped in both years, decreasing in higher numbers in the first year. The estimated mean infestation levels for all of the tick’s life cycle forms in the six monitored spots did not reach one individual in the end of the study. Estimated mean infestation levels for nymphs in these places equaled zero.

title: Implication of the fecal egg count reduction test (FECRT) in sheep for better use of available drugs

description: Abstract The aim here is to present data on the efficacy of anthelmintics in sheep flocks in Rio de Janeiro, Brazil, and to discuss the interpretation of the fecal egg count reduction test (FECRT) for each nematode genus. Fecal eggs counts and pre- and post-treatment coprocultures were performed, the former to evaluate the efficacy of and the latter to determine the overall parasite prevalence. An additional efficacy test was performed at Farm # 1 a year after the initial test. Severe anthelmintic resistance was found for the flocks, with no FECRT sensitivity at any of the 22 farms evaluated. However, an analysis of the infective larvae showed that some drugs were effective against certain parasitic genera; i.e., levamisole was more effective against Haemonchus spp. and moxidectin against Trichostrongylus spp. In the additional FECRT performed at Farm # 1, moxidectin and nitroxynil were ineffective separately, but when applied in combination they were highly effective due to their efficacy against Haemonchus (nitroxynil) and Trichostrongylus (moxidectin), respectively. The use of the FECRT targeting the parasitic nematode species prevalent on farms may make it possible to choose more effective anthelmintics.

title: Anthelmintic activity of Eucalyptus citriodora essential oil and its major component, citronellal, on sheep gastrointestinal nematodes

description: Abstract This study aimed to evaluate the anthelmintic activity of Eucalyptus citriodora essential oil and citronellal on sheep gastrointestinal nematodes. Essential oil composition was determined by gas chromatography mass spectrometry. The substances were evaluated in vitro using adult worm motility test (AWMT) and transmission electron microscopy (TEM). The acute toxicity test in mice and the fecal egg count reduction test (FECRT) in sheep were performed. Citronellal was confirmed as the essential oil major constituent (63.9%). According to the AWMT, 2 mg/mL of essential oil and citronellal completely inhibited Haemonchus contortus motility at 6 h post exposure. H. contortus exposed to essential oil and citronellal exhibited internal ultrastructural modifications. The lethal dose 50 values in mice were 5,000 and 2,609 mg/kg for essential oil and citronellal, respectively. E. citriodora essential oil reduced sheep epg at 14 days post treatment by 69.5% (P&lt;0.05). No significant differences were observed in epg between the citronellal and negative control groups (P&gt;0.05). The interaction between citronellal and other constituents in the essential oil may be relevant for its in vivo anthelmintic activity. Thus, E. citriodora essential oil and citronellal pharmacokinetic studies may help elucidate the anthelmintic activity of these compounds.

title: Simulation of flow condition in circular pipe transporting Paragominas bauxite slurry in the presence of a viscosity modifier

description: ABSTRACT Ore pumping systems flowing through pipelines has attracted the interest of mining companies as it might become a very efficient alternative of transport. Friction factor estimation is believed to be one of the greatest challenges in such projects because it is affected by many variables. A 52 % (w/w) Paragominas bauxite slurry sample was characterized according to its physical, mineralogical, and rheological properties. The properties of the sample were 74 µm d50 size, 1455 kg/m3 specific gravity, and 0,011 Pa.s viscosity. Mineralogical composition of the sample was essentially bauxite, and it also contained other minerals such as goethite, hematite, kaolinite, anatase. Rheological tests revealed that the role of sodium hexametaphosphate was as deflocculant of the slurry. The concentration of the sodium hexametaphosphate in which viscosity values reached a minimum value was equivalent to 250 g of additive/ton of bauxite. The rheological behavior of bauxite samples studied was modeled according to Herschel-Bulkley equation. Friction factor of both samples with and without additive was estimated by applying Dodge-Metzner correlation, simulating the real flow conditions at the bauxite slurry pipeline in Paragominas. Results showed that friction factor values of samples containing additive reduced 12 % average compared to the samples without any additive.

title: There is an Autistic Student in my Class! Now What? The Reflexive Journal Promoting Professional Sustainability in the Development of Pedagogical Opportunities for Inclusion

description: ABSTRACT Higher Education has overcome the barriers of inclusion by envisioning the training of self-employed professionals prepared for the professions of the future. Considering the use of the reflexive journal technique in education, its effectiveness in the confluence of the demands of teaching for competence, exercise of active methodologies and inclusion promoted by the professional sustainability of a professor without special education training is questioned in this paper. The objective was to evaluate, through the systematic content analysis, three pedagogical practices recorded according to premises and practical arguments in teaching with (Biological Sciences) and without (Psychology) autistic students. The intervention was guided by the implementation of active methodologies during the school semester. The results indicate the effectiveness of the technique, since the identification of the problem, reflection and decision making had effects on the performance of the professor, crossing the development of skills in students with special educational needs, sensitizing them to overcome limitations also of neurotypic students.

title: Non destructive test in ceramic coating using a prototype for detection of pathology

description: ABSTRACT In the construction sector there is a growing investment in the maintenance and repair of constructions, such as the pathologies found on floors with ceramic coating. Among the most common pathologies, it is possible to highlight the inadequate seating of the ceramic floor, which are characterized by the loss of adhesion of some plates to their base (substrate). Due to the probability of accidents involving users and the high costs of repair, this is considered an important pathology. The objective of this work is to present a new nondestructive test methodology, based on the development of a tool based on the kinetic and acoustic response of a prototype, which, when a ceramic floor with the loss of adhesion is produced, produces “cavo” sound and a significant loss of to identify the occurrence of this pathology. Six types of ceramic flooring were used, in compliance and in conformity with the Brazilian standard, and then the coefficients of restitution of each plate were determined. The impact sounds on the boards were also picked up by a microphone and a piezoelectric pickup and processed through the Realtime Analyzer program, which produces charts that relate frequency, amplitude, sound energy, and time. The results obtained by the prototype were compared to other non-standard methods: wood rod, threaded rod, steel bar and metal sphere. It was concluded that the prototype is feasible for the detection of pathology of settlement of ceramic floor, proving to be a preventive and non-destructive strategy.

title: A study on the compressive strength and microstructure characteristic of alkali-activated metakaolin cement

description: ABSTRACT The main purpose of this study was to investigate the compressive strength and microstructure characteristic of alkali-activated metakaolin cement (AAMC). In accordance with this purpose, besides the pure metakaolin activation five other mixtures were designed by substitution of different OPC ratios instead of metakaolin (MK) from 0 to 25 (5, 10, 15, 20, 25% OPC). AAMC was activated with sodium silicate (Na2SiO3) of modulus Ms = SiO2/Na2O = 3.1 and NaOH solutions (32% of NaOH, 68% of water by mass). The ratio of liquid/solid (L/S) was kept constant at 0.65. All specimens were cured at 70 °C for 72 hours then kept in room conditions until the days that experiments were performed. Compressive strength and UPV experiment tests were carried out on all specimens at different curing periods of 3,14,28 and 90 days. In addition, the microstructure of 28 days alkali-activated metakaolin cements were analyzed with scanning electron microscope (SEM). The results showed that AAMC specimens reached the desired strength and major part of the final strength was gained at the end of 3 days of curing.
