Particleboard produced with sawmill waste of different wood species

This study aimed to investigate physical performance of particleboards produced with waste from sawmills, containing different wood species, and two adhesives: urea-formaldehyde (UF) based resin and castor-oil (PU) based bi-component polyurethane resin. Panels were produced with nominal density 0.8gcm(-3); pressing temperature 110 degrees C; pressing time 10 min; specific pressure 5 MPa. Water absorption (2 and 24h); thickness swelling (2 and 24h); density; and moisture content were investigated. Results confirmed that the produced panels presented compatible physical properties in comparison with other researches referred in literature, proving the feasibility of inputs employed. Panels produced PU showed better performance than those produced with UF.

Biodegradação da vinhaça resíduo da produção de etanol

The State of São Paulo is responsible for the largest sugar cane production in Brazil, as well as the largest production of ethanol made of this raw material – which is widely used as fuel for automobiles. This utilization began in the 1970’s, with the institution by the Brazilian government of the National Alcohol Program (PRO-ÁLCOOL), as a consequence of the petroleum crisis, rising again five years ago, with the development of flex fuel cars. The obtaining process of ethanol originates residues; amongst them, vinasse is the one that’s generated in the largest amount (an average of 10 to 13 litres/litre of ethanol produced). The disposal of this residue in waters was only forbidden in 1978, but before that, researchers had already been investigating its utilization as raw material. This paper had the objective of accompany the biodegradation of vinasse by evaluating the oxygen comsumption during it until the ultimate Biochemical Oxygen Demand (uBOD), performed in twenty days; another objective was to analyse the biomass production of Saccharomyces cerevisae in this residue. Physical and chemical analyses of the residue were also performed, as well as acute toxicity essays using Daphnia similis and Dugesia tigrina, before and after its biodegradation. The physical and chemical analyses pointed elevated acidness (pH = 3,98), conductivity (8,30 mS/cm) and COD (25.693,43 mg O2/L) and mean quantity of suspended solids (5.246 mg/L). The toxicity essays indicated absence of toxic potential in vinasse after biodegradation for both species. The uBOD degradated until 88,22% of the COD, demonstrating the possibility of biodegradation of most of the residue’s organic load in a relatively short period of time. S. cerevisae caused a 37,03% COD diminution in vinasse, diminished its conductivity and promoted a slight elevation of the pH; it obtained low biomass...(Complete abstract click electronic access below)

Evaluation of stryphnodendron sp. release using natural rubber latex membrane as carrier

Natural rubber latex from Hevea brasiliensis has interesting characteristics related to this work such as: it is easy to manipulate, low cost, can stimulate the natural angiogenesis, is a biocompatible material and presents high mechanical resistance. The aim of this study was to develop a novel sustained delivery system for Stryphnodendron sp. based on Natural Rubber Latex (NRL) membranes and to study the Stryphnodendron sp. delivery system behavior. Stryphnodendron sp., commonly known as barbatimao is extensively used in folk medicine for the treatment of diarrhoea, gynaecological problems and for healing wounds. The stem bark of this species is mentioned in the Brazilian Pharmacopeia with a content of at least 20% of tannins. Previous studies showed significant cicatrizant properties, anti-inflammatory activity and gastric anti-ulcerogenic effects for the stem bark crude extract. One possible way to accelerate the tissue repair process, it was incorporated the Stryphnodendron sp. extract in NRL membranes. Stryphnodendron sp extract was incorporated into the NRL, by mixing it in solution for in vitro protein delivery experiments. Results show that the NRL membrane can release Stryphnodendron sp. for up to 49.89% of its Stryphnodendron sp. content for up 400 h. The kinetics of the extract release could be fitted with double exponential function, with two characteristic times of 0.78 and 133.22 h. In this study, we demonstrated that the induced angiogenesis provided by NRL membranes combined with a controlled release of extract is relevant for biomedical applications.

Prevalência de alterações sistêmicas em pacientes atendidos na disciplina de cirurgia e traumatologia bucomaxilofacial do curso de Odontologia da UNIARA

Introduction: pre-operative assessment is of fundamental importance for the prevention of transoperative and of postoperative complications. Objective: to identify the prevalence of diseases and systemic conditions in patients undergoing surgical treatment in the discipline of surgery and Traumatology of University Center of Araraquara, in the period of 2004 to 2009. Material and method: for the development of this study, a survey in medical records of patients was performed and the factors considered included: age, sex, presence of vices, and systemic conditions that affect the world’s population. The data obtained were analyzed quantitatively and recorded in a table. Result:  Considering all patient records analyzed (693), 340 affirmative responses were detected (49,06%) to one or more diseases. Cardiovascular diseases were the most prevalent (22,34%). Considering the prevalence of diseases related to age, the age of less than 20 years represented 16,32%; of 20-29 years, 43,06%; 30-39 years, 45,16%; 40-44 years, 48,64%; 45-49 years, 56,25%; 50-54 years, 58,33%; 55-59 years, 57,74%; 60-64 years, 70,37%; 65-69 years, 66,66%; and 70 years or more, 68,75%. Conclusion: diseases and systemic alterations with higher prevalence were cardiovascular diseases, anemia, sinusitis and diabetes. The frequency of affirmative answers to systemic conditions was age-dependent and there was a predominance of females. The tobacco addiction was the most frequent. Thus, it was found that the preoperative assessment of the health of patients who will undergo surgical dental treatment is of fundamental importance.

Estudo do comportamento reológico de sucos combinados de frutas vermelhas

The aim of this work was to evaluate the rheological behavior of combined juices of strawberry, blackberry and raspberry in two different temperatures of interest in industrial processes in the food industry, using rheological analyses on non-oscillatory regime and the Response Surface Methodology (RSM). The rheological data were fitted by the Casson model. All samples of combined juices of ref fruits showed a Newtonian behavior and the rheological parameters yield stress (Kc) and plastic viscosity of Casson (Koc) had a decrease in its values with the temperature increase. By the analysis of the ternary diagrams it is evident that the raspberry juice effectively contributed to the higher values of yield stress and plastic viscosity of Casson in both temperatures studied.

Exercise training improves ambulatory blood pressure but not arterial stiffness in heart transplant recipients

BACKGROUND: Hypertension is the most prevalent comorbidity after heart transplantation (HT). Exercise training (ET) is widely recommended as a key non-pharmacologic intervention for the prevention and management of hypertension, but its effects on ambulatory blood pressure (ABP) and some mechanisms involved in the pathophysiology of hypertension have not been studied in this population. The primary purpose of this study was to investigate the effects of ET on ABP and arterial stiffness of HT recipients.METHODS: 40 HT patients, randomized to ET (n = 31) or a control group (n = 9) underwent a maximal graded exercise test, 24-hour ABP monitoring, and carotid-femoral pulse wave velocity (PWV) assessment before the intervention and at a 12-week follow-up assessment. The ET program was performed thrice-weekly and consisted primarily of endurance exercise (40 minutes) at similar to 70% of maximum oxygen uptake (Vo(2MAX))RESULTS: The ET group had reduced 24-hour (4.0 +/- 1.4 mm Hg, p < 0.01) and daytime (4.8 +/- 1.6 mm Hg, p < 0.01) systolic ABP, and 24-hour (7.0 +/- 1.4 mm Hg, p < 0.001) daytime (7.5 +/- 1.6 mm Hg, p < 0.001) and nighttime (5.9 +/- 1.5 mm Hg, p < 0.001) diastolic ABP after the intervention. The ET group also had improved Vo(2MAX) (9.7% +/- 2.6%, p < 0.001) after the intervention. However, PWV did not change after ET. No variable was changed in the control group after the intervention.CONCLUSIONS: The 12-week ET program was effective for reducing ABP but not PWV in heart transplant recipients. This result suggesfs that endurance ET may be a tool to counteract hypertension in this high-risk population. (C) 2015 International Society for Heart and Lung Transplantation. All rights reserved.
