1. Quais os principais tratamentos para a hiperidrose axilar em ambiente de atenção primária à saúde?
De acordo com revisão realizada pelo
, o primeiro tratamento ambulatorial a ser realizado em ambiente de atenção primária preconizado para hiperidrose idiopática é o uso de antiperspirantes a base de sais de alumínio (“aluminium chloride hexahydrate” a 20% em álcool). Embora seu uso possa ser feito em casos de hiperidrose idiopática le

2. Shelf-life assessment of energy banana bar using acceleration method with critical moisture content approach
Abstract The shelf-life of the product need to be evaluated according to the commercialization of the product. Shelf-life assessment of the product can be done using acceleration method (Accelerated Shelf-life Testing) with critical moisture content approach. This research used the acceleration method to predict the expired date of the energy bar based banan

3. Formulation and characterization of protein-energy bars prepared by using dates, apricots, cheese and whey protein isolate
Abstract Six protein energy-bars (B1-B6) were prepared for Pakistani-athletes using dates, dried apricots, Cheddar-cheese and whey-protein isolate. Bars B1-B3 contained 5 g Cheddar-cheese and 13 g whey-protein isolate while quantity of dates were 74, 68 and 65 g and apricots 8, 14 and 17 g respectively. Bars B4-B6 contained 8g Cheddar-cheese and 12 g whey pr

4. Extract of Ellagitannins starting with Strawberries (Fragaria sp.) and Blackberries (Rubus sp.)
Abstract Characterize the content of phytochemical compounds present in samples of extracts of strawberry (Fragaria sp.) and blackberry (Rubus sp.). The extraction of said compounds was carried out with solutions of polar solvents, such as acetone, ethanol and methanol, using an experimental design with three factors: state of maturity, resting time and temp

5. The effects of two abundant ant species on soil nutrients and seedling recruitment in Brazilian Atlantic Forest
ABSTRACT Ants can influence soil fertility and the spatial distribution of seeds, with possible effects on seedling recruitment. The ant species Pachycondyla striata Fr. Smith, 1858 and Odontomachus chelifer (Latreille, 1802) co-occur in many forest areas in the Neotropics. We assessed soil fertility and seed bank structure in soil samples close and distant

7. Mechanical Properties and Metallurgical Characterization of LM25/ZrO2 Composites Fabricated by Stir Casting Method
ABSTRACT Zirconia (ZrO2) dispersed aluminum alloy metal matrix composites produced by stir casting techniques. Using stir casting techniques, aluminium based composites with varying amounts of 3%, 6%, 9%, and 12% of zirconia by weight are fabricated. The prepared samples were subjected to physical, mechanical,tribiology and microstructure investigation. The

8. Tensile and fatigue properties, machinability and machined surface roughness of Al-Si-Cu alloys
ABSTRACT In this paper, the aim was to determine if ASC91 (9 % Al, 1 % Cu) could be replaced with ASC73 (7 % Al, 3 % Cu) aluminium alloy, with presumably improved machinability due to lower silicon content (9 to 7 %) and retained mechanical properties due to a higher copper content (1 to 3 %). The test samples were excised from cylinder heads produced by the

9. Effect of Extrusion and Heat Treatment on Microstructure and Mechanical Properties of Hypereutectic A390-0.3wt%Nd Alloy
An hypereutectic aluminium alloy with a composition of 16-18wt%Si, 4-5wt%Cu, 0.45-0.65wt%Mg, 0.3wt%Nd and Al balance (A390-0.3wt%Nd alloy) was processed by extrusion and aging at 200ºC for 10 hours. The effect of the thermomechanical processing and heat treatment on microstructure and mechanical properties was investigated for A390-0.3wt%Nd alloy. It was sh

11. Corrosion and Micro-abrasive Wear Behaviour of 2524-T3 Aluminium Alloy with PAni-NPs/PSS LbL Coating
In this paper, we present an alternative method to obtain thin films for coating protection on the surface of the AA2524-T3 Al-alloy by using the Layer-by-Layer (LbL) technique. The LbL films were fabricated by alternated immersion of the Al-alloy into a poly(styrene sulfonate) (PSS) and polyaniline nanoparticles (PAni-NPs) solutions, obtaining a PAni-NPs/PS

12. Tolerance of Eucalyptus and Pinus seedlings to exchangeable Aluminium
ABSTRACT: Tolerance to acid soil is an important trait of Eucalyptus and Pinus species introduced into commercial forestry plantations in tropical ecosystems. The objective of this study was to evaluate the effect of the exchangeable Al on growth of the seedlings of two species and one hybrid of Eucalyptus and two species of Pinus. We also wanted to identify
