title: INFLUENCE OF TIME AND HEAT TREATMENT TEMPERATURE ON PERMEABILITY OF Eucalyptus grandis WOOD

description: ABSTRACT Due to the fact that raw timber has permeability characteristics unsuitable for some applications, several processing techniques have been developed, such as hydrothermal treatments and freezing, which aim to improve these properties. The objective of this study was to analyze the effects of treatment temperature and duration on the permeability of Eucalyptus grandis wood. Heartwood samples from three E. grandis trees were utilized, each with the dimensions 30 x 8 x 3 (length, width, thickness). The treatments were carried out at three temperatures (-20°C, 60°C, and 100°C) and three exposure durations (5, 10, and 15 hours). Treatments at -20°C were conducted inside a domestic freezer, while treatments at 60°C and 100°C took place inside a Parr Reactor, while the wood being submerged in water. Extractive removal was only observed at the surface and interior of wood treated at 60°C and 100°C; while all treatment conditions increased permeability with respect to control treatments.

title: Superior vena cava syndrome: endovascular management

description: Abstract Background The objective of management of superior vena cava syndrome (SVCS) is to promptly alleviate the uncomfortable symptoms. Conventional approaches do not always achieve results as rapidly as endovascular management with stent placement. Objectives To report the experience with endovascular management of SVCS of a Vascular and Endovascular Surgery Service at a Brazilian university hospital. Methods Symptomatic type III SVCS cases were managed with angioplasty and stent placement in 28 patients aged from 37 to 68 years, between 2002 and 2012. The etiology of SVCS was lung or thoracic cancer in 18 patients, while occlusion of the vein for prolonged use of catheters was the cause in the other 10 cases. Results Superior vena cava occlusion repair was not possible in one oligosymptomatic patient with a very severe lesion. Technical success was achieved in 96.4%. There were two deaths, one due to pulmonary embolism, 24 hours after a successful procedure, and the other due to compression of the airways by tumor mass some hours after the procedure. Clinical success was achieved in all cases of technical success, including one patient who died suddenly, after total regression of SVCS symptoms. Symptoms disappeared 24 hours and 48 hours after management in16 and 8 patients respectively; improvement was slower but progressive after 48 hours in the remaining patients. Conclusions Endovascular stent placement was effective for management of SVCS, with good technical and clinical success rates and provided prompt relief from symptoms.

title: The normalization of wave functions of the continuous spectrum

description: Abstract The continuous spectrum of a quantum mechanical (QM) system contains important information on the system. However, the normalization of wave functions of the continuous spectrum is often difficult and therefore is often omitted from the books on QM. We discuss this problem and show how we can overcome this problem technically, with some examples.

title: QUALITY OF LIFE OF PATIENTS WITH SARCOMA AFTER CONSERVATIVE SURGERY OR AMPUTATION OF LIMBS

description: ABSTRACT Objective: To conduct an integrative review on quality of life (QOL) of patients with sarcoma who underwent conservative surgery or limb amputation. Methods: We conducted a six-step integrative review by searching the databases LILACS, SciELO, PePSIC, Embase, and PubMed, using the descriptors: “Quality of life”, “Bone cancer”, “Sarcoma”, “Limb Salvage,” and “Amputation.” Ten studies were selected according to: database, type of study, methods, researcher's profession, sex, histological type, title, country/region, and periodical/year of publication. Results: Nine quantitative and one qualitative studies were included. All were conducted by physicians and correlated to QOL with the impact of diagnosis, psychosocial aspects, cancer treatment, and survival. Other aspects included type of surgery, functionality, rehabilitation, and a multidisciplinary approach. The QOL results were similar for conservative surgery and amputation in eight studies. In two, it was concluded that patients undergoing conservative surgery had a better QOL. Conclusion: The number of studies on QOL in patients with sarcoma is small. In most, there was no difference between the study groups. In addition, the studies indicated the importance of evaluation of QOL, since it has a direct effect on patients' physical manifestations and impacts their coping abilities. Level of evidence III, System review.

title: Students’ argumentation in the creation and critique of analogies of Thomson’s Atomic Model

description: Abstract: In this paper, we aim to explain how the strategy for the creation and critique of analogies of Chemistry students can favor engagement with argumentation and the learning of the atomic model proposed by Thomson. A Didactic Unit was produced and used with a first-year high school class. The class was recorded on audio and video, and a case study was developed of a group of students. The analysis of the case indicates that the students were involved in argumentation when they presented the correspondences and limitations of comparisons, which favored the defense of their opinions, the rejection, and assessment of ideas concerning their comparisons. The strategy contributed to the learning of complex aspects related to the model, such as the movement of electrons. We believe that this strategy may be potentially useful in the context of Chemistry teaching.

title: Pine and sugarcane bagasse particleboard using two adhesives for use in the construction industry

description: Abstract This research project aimed to produce and evaluate particleboard using sugarcane bagasse (Saccharum officinarum) and pínus (Pinus taeda; Pinus elliotti) particles by comparing the efficiency of the two adhesives: urea-formaldehyde and polyurethane adhesive based on castor oil. The panels were made with 60% of pine wood particles, and 40% of sugarcane bagasse particles. The physical properties (density, moisture content and thickness swelling after 24h in water immersion), and mechanical properties (modulus of elasticity, modulus in static bending, and perpendicular traction to faces) of the panels were evaluated according to the use requirements set by the standards NBR 14810-1 (ABNT, 2013a), NBR 14810-2 (ABNT, 2013b) and EN-312. Panels produced with PU-Castor presents higher efficiency and compatibility with the physical and mechanical requirements of Brazilian and European standards for panels of type P6 (structural panels for use under severe load conditions in dry conditions). Panels produced with urea-formaldehyde are compatible with panels classified as P2 (non-structural panels for use in dry conditions). The results achieved proved the effectiveness of the panels produced, which can be used in the furniture and construction industries.

title: Tracheal avulsion in a cat

description: ABSTRACT: Tracheal avulsion is a condition seen in small animals and occurs as a result of a traumatic incident to the cervical and/or thoracic regions. The aim of this study is to report a case of tracheal avulsion in a cat using imaging examinations for diagnostic investigation. In this report, we examined an eight-month-old male, cat of undefined breed, diagnosed with tracheal avulsion using complementary imaging tests. This diagnosis was confirmed with post-mortem examination. Radiographic examination of the patient’s thorax and a tracheoscopy were performed. These examinations revealed complete discontinuity of the tracheal circumference, the presence of focal and circumscribed dilation of the tracheal lumen and stenosis. The patient quickly died without clinical and surgical intervention. Macroscopic analysis revealed a tracheal diverticulum confirming the findings of the imaging tests. The use of radiographic examinations in conjunction with tracheoscopy was effective at diagnosing this condition.

title: Review of accelerated tests for the induction of corrosion triggered by chlorides in reinforced concrete

description: Abstract Reinforcement corrosion triggered by chlorides is one of the main problems that affects reinforced concrete structures. Considering the study of this kind of problem, the speed of data collection, the possibility of controlling the variables that influence the corrosion process and the low cost of carrying out these tests have been encouraging aspects for carrying out laboratory accelerated tests rather than testing based on natural exposure. Over the years, although the procedures adopted in accelerated tests have improved, research in the field is still lacking widely used standardisation. This study undertakes a review of the main testing methodologies used to induce corrosion triggered by chlorides in Brazil and internationally, discussing their advantages and disadvantages and generating a reflection about the standardisation of procedures. Hence, it proposes, among other aspects, the use of accelerated testing procedures that keep a proximity with real exposure conditions, the standardisation of the criteria used to identify reinforcement depassivation, as well as of specimens preparation. These actions can contribute to reduce data variability and facilitate comparisons among similar studies.

title: Drying kinetics modeling of apple and zucchini slices vacuum impregnated with anthocyanins

description: ABSTRACT: The aim of this research was to study the drying kinetics of apple and zucchini slices enriched with anthocyanins and to evaluate the influence of drying temperature on the anthocyanin content of apple and zucchini snacks. Apple (Granny Smith) and zucchini (Cucurbita pepo) slices were enriched with anthocyanins by vacuum impregnation with blueberry juice. Then, slices were dehydrated at 40, 50 and 60 ºC with 1.0 m/s air flow. Dehydrated samples were referred to as anthocyanin enriched snacks. Diffusion coefficient values improved by increasing the drying temperature, within the 2.81×10-10 to 5.78×10-10 m2/s range for apple slices and 2.02×10-10 to 3.99×10-10 m2/s for zucchini slices. The activation energy was 31.19 kJ/mol and 80.33 kJ/mol for apple and zucchini slices respectively. Page, Weibull, Logarithmic, Henderson-Pabis and Lewis models best fitted the experimental data. Snacks obtained at 60 °C retained a higher concentration of anthocyanins, reaching values of 592.81±52.55 and 464.62±48.44 mg of cyaniding-3-glucoside equivalent/kg dry matter in apple and zucchini snacks respectively. Combination of vacuum impregnation and hot air drying was a technological alternative for producing snacks with functional properties.

title: Human Heat stress risk prediction in the Brazilian semiarid Region based on the Wet-Bulb Globe Temperature

description: Abstract: Objective: the aim of this study is to map thermal stress risks for human health at the São Francisco River Basin (SFRB) in the Semiarid region, for climatic scenarios RCP 4.5 and 8.5. Methods: The heat stress conditions were defined by the Wet Bulb Globe Temperature (WBGT) indicator and by the average number of annual days in which the WBGT values exceeded the 90th percentile of the reference period. The WBGT was estimated for the climate scenarios RCP 4.5 (intermediate) and 8.5 (pessimistic) for the period 2011-2090 comparing to the period of reference (1961-2005). Results: The projections show that for the pessimistic scenario practically all municipalities of the SFRB region can reach values of WBGT that indicate a high risk for heat stress in the period 2071-2099. For this same scenario and period, the municipalities of the Lower and Under-average regions may present values of WBGT above the 90th percentile of the reference period in more than 90% of the days/year. Conclusions: These results show that, if the emission of greenhouse gases continues in the present proportions, some municipalities of the SFRB region may present a high risk for heat stress affecting the work capacity and the practice of physical exercises.

title: Estimation of genetic merit of diallel hybrids of sweet pepper by mixed models

description: ABSTRACT: The use of mixed models for evaluating diallel crosses is a highly timely option to the reliable prediction of progeny genetic values. In the sweet pepper crop, hybrids are commercially explored on a large scale, mainly because of their characteristics of economic importance. This study aimed to assess the potential of hybrids obtained from a partial diallel among five sweet pepper lines developed for the hydroponic cultivation system and two simple hybrids, by applying mixed models. It was performed crosses in the partial diallel scheme among the (L1B, L6, L7, L18, and L19) lines and the simple hybrids ‘Valdor’ and ‘Atlantis’. Plants were cultivated in hydroponic system with substrate and irrigated three times a day using nutrient solution. On the basis of mixed models, the following traits were assessed: mean fruit diameter (FD), mean fruit length (FL), mean fruit number per plant (FNP), mean fruit mass (FM), early yield (EYIELD), and mean fruit mass per plant (FMP). The L6 line was the one that showed the highest estimate of general combination capacity for FMP, FM, and EYIELD, proving to be promising for recommendation. The hybrid that provided the best specific combining ability for FD, FM, FMP, and EYIELD was L6 x ‘Valdor’. Triple hybrids were efficient to maximize yield for the traits of interest by the use of the mixed model.
