title: Study of K-40, Ra-226, Ra-228 and Ra-224 activity concentrations in some seasoning and nuts obtained in Rio de Janeiro city, Brazil

description: Abstract This work presents an investigation of the activity concentration (AC) of naturally occurring radionuclides in 26 samples of seasoning and nuts utilized for Brazilian population. The samples were measured using gamma spectroscopy technique with a high-purity germanium detector. The analysis shows that K-40 AC was measured in all samples, and its AC ranges from 21.0 Bq/kg to 1288 Bq/kg. The highest K-40 AC was measured for cheiro verde, a Brazilian seasoning made of chives (Allium schoenoprasum) and parsley ( Petroselinum crispum), while annatto, made with the fruit of Bixa orelhana , presented the lowest AC. Brazil nut (Bertholletia excelsa ) presented the highest AC for Ra-226 and Ra-228 with 24 Bq/kg and 25.7 Bq/kg, respectively, and black pepper (Piper nigrum) presented the highest Ra-224 AC, with 33.9 Bq/kg. Behavior of radionuclides present in the seasoning samples and dose percentage due to ingestion was evaluated. The highest effective dose for members of the public due to idealized intake of 1 kg of seasoning was 23.5 µSv/y due to Brazil nut and the lowest effective dose was found for annatto: 0.13 µSv/y. The Syrian seasoning was the only sample that presented a measurable amount of Cs-137, (6.1 ± 1.1) Bq/kg for AC and 0.08µSv/y for effective dose.

title: Influence of the heat treatment of sugarcane juice on the fermentative process and chemical composition of cane spirit

description: Abstract The introduction of different strains of microorganism in the fermentations destined for the production of cane spirit, due to successive broth feeds, may contribute to the development of different classes of microorganism, compromising the metabolic activity of the yeasts and hence the direction of the fermentative process. Thus the present study aimed to evaluate the influence of the heat treatment of the sugarcane juice on the technological and microbiological characteristics of the substrate and their effects on the direction of the fermentative process and the chemical quality of the cane spirit. The juice was treated at 90 °C for 5 minutes and the concentrations of lactic bacteria, total yeasts and non-Saccharomyces yeasts then quantified. Five fermentative cycles were carried out using heat treated and untreated sugarcane juice musts. The process was monitored via cell viability and bud production and determination of the budding index, and the total and non-Saccharomyces yeast populations quantified in the recycled yeast. At the end of the fermentations, the pH, total titratable acidity, alcohol content by volume and total residual reducing sugars of the wines were determined, these being distilled in a copper still for quantification of the chemical composition of the cane spirit. The heat treatment allowed for inactivation of the microorganisms in the juice without compromising their physicochemical characteristics. The cell viability was reduced when the fermentations were carried out with untreated juice, although the physicochemical characteristics of the wines were not affected. The distillates from fermentations carried out with untreated juice showed higher levels of volatile acidity and esters at the end of the 5th cycle. The concentrations of higher alcohols and furfural were elevated for both treatments in the 1st and 5th cycles, respectively.

title: Effect of a palliative care program on trends in intensive care unit utilization and do-not-resuscitate orders during terminal hospitalizations. An interrupted time series analysis

description: ABSTRACT Objective: To assess the effect of the implementation of a palliative care program on do-not-resuscitate orders and intensive care unit utilization during terminal hospitalizations. Methods: Data were retrospectively collected for all patients who died in a tertiary hospital in Brazil from May 2014 to September 2016. We analyzed the frequency of do-not-resuscitate orders and intensive care unit admissions among in-hospital deaths. Interrupted time series analyses were used to evaluate differences in trends of do-not-resuscitate orders and intensive care unit admissions before (17 months) and after (12 months) the implementation of a palliative care program. Results: We analyzed 48,372 hospital admissions and 1,071 in-hospital deaths. Deaths were preceded by do-not-resuscitate orders in 276 (25.8%) cases and admissions to the intensive care unit occurred in 814 (76%) cases. Do-not-resuscitate orders increased from 125 (20.4%) to 151 (33%) cases in the pre-implementation and post-implementation periods, respectively (p &lt; 0.001). Intensive care unit admissions occurred in 469 (76.5%) and 345 (75.3%) cases in the pre-implementation and post-implementation periods, respectively (p = 0.654). Interrupted time series analyses confirmed a trend of increased do-not-resuscitate order registrations, from an increase of 0.5% per month pre-implementation to an increase of 2.9% per month post-implementation (p &lt; 0.001), and demonstrated a trend of decreased intensive care unit utilization, from an increase of 0.6% per month pre-implementation to a decrease of -0.9% per month in the post-implementation period (p = 0.001). Conclusion: The implementation of a palliative care program was associated with a trend of increased registration of do-not-resuscitate orders and a trend of decreased intensive care unit utilization during terminal hospitalizations.

title: A proposal to integrate the BIM model with the Last Planner system

description: Abstract This study investigated the use of building information modelling (BIM) integrated with the logics of the Last Planner system in construction planning and control in building projects. The aim of the study was to build an integrative model in order to improve the planning process in both the medium and short terms. The methodological approach adopted was Design Science Research, which prescribes the design and development of innovative devices (in this study, a model) to solve practical problems. The integration model involved the development of a plug-in for the Revit software, capable of providing information on a database powered by another software. Hence, it was possible to establish the terials, labor, work, and design specifications. The evaluation of the model was made through an empirical study on a large building site. The main conclusion was the resulting synergy between the model and the Last Planner system, through relationship between each geometric element of the project and its needs for maautomatic verification of constraints, visual management, and integration of the parties involved with medium and short-term planning, making them more efficient.

title: The role of human milk and sucrose on cariogenicity of microcosm biofilms

description: Abstract This study investigated the effect of human milk, alone and associated with sucrose, in the cariogenicity of biofilms in a microcosm biofilm model and compared with the cariogenicity of sucrose and bovine milk. Microcosm biofilms were grown in enamel discs in 24-well plates. Six growth conditions were studied: DMM (chemically defined artificial saliva - negative control), DMM with 1% of sucrose (DMM+s) (positive control), human milk with DMM, human milk with DMM+s, bovine milk with DMM, and bovine milk with DMM+s. After 5 days, the outcome variables surface hardness change (%SHC), microbiological composition of biofilms, and pH of supernatant were analyzed. All groups had significantly lower hardness loss compared to the DMM group with 1% of sucrose. Human and bovine milk associated with sucrose showed higher hardness loss. The supernatant pH values after 6 hours of different treatments were similar for the groups sucrose and human milk associated with sucrose (p&gt;0.05). After 18 hours at rest in pure DMM, an increase in the pH of the supernatant was observed. Higher values of total microorganisms count were found for sucrose and bovine milk groups compared to the group supplemented only by DMM. Bovine milk group showed greater amount of total aciduric microorganisms in comparison to human milk group. Within the limits of this study, it can be infered that both human and cow milks have some cariogenic potential, although differing from sucrose in terms of mineral loss.

title: Finite element evaluation of the effects of curvature in Lamb waves for composites structural health monitoring

description: Abstract This work presents the effect of the high curvature to thickness ratio on the characteristics of Lamb Waves propagating over the skins of composite structures. It is accessed how the curvature on composite skins affects the group velocity of the symmetrical (S0) and asymmetrical (A0) wave modes. It is also accessed the gradient of curvature effect, when the wave propagates from a flat to a curved part on the skin. The results are intended to be used for the improvement of structural health monitoring of wings and wind turbine blades. This is accomplished through dynamic explicit linear finite element method simulations of plates with flat and curved parts made of Eglass-epoxy bidirectional laminate. As the skin structures are often designed to withstand torsional loads, the fibers are aligned with 45 degrees from the leading edge (curved region) throughout the analysis. Several skins with different curvature to thickness ratios are generated and simulated. Results and trends are presented and can be used to improve the algorithms for damage detection on those structures. It is shown that the group velocity of the incoming waves change considerably with the presence of curvature, for both main modes of vibration.

title: Different sources of sulfur in diets of adult cats on the urinary parameters and acid-base balance

description: ABSTRACT: Urolithiasis is a common disorder in the veterinary clinic and is considered as one of the most frequently cause of morbidity. This disorder is closely associated with urinary pH and nutrition plays a key role in the control of this disease, because through dietary manipulation it is possible to modify the urinary pH. Sulfur is considered macroelement with a strong influence on the acid-base status and may be crucial to control urinary pH in cats. The purpose of this study was to evaluate the effects of addition of different sources of sulfur (S) in the diet of cats on the urinary parameters and acid-base balance. Forty-two healthy adult cats were divided into 3 groups, and each group of 14 cats received 7 diets in a complete randomized block design. Calcium sulfate (CaSO4), DL-methionine (DLM) and methionine hydroxy analog (MHA) were added to a control diet in two levels (1.28g S/kg and 2.56g S/kg) to formulate 6 other experimental diets. The acid-base balance was evaluated by hemogasometry in samples of venous blood. The DLM at the highest level and MHA differed of the control diet in relation to urinary pH (P&lt;0.05). Calcium sulfate; although, not differentiated from the control diet, has been shown to alter urinary pH despite its zero electrolyte balance. Apparently, the alkalizing effect of calcium was not sufficient to avoid sulfate acidification of the urine. Treatments showed no alteration of the acid-base balance of the animals and no affect the consumption of the diets.
