1. Optimum design of steel columns filled with concrete via genetic algorithm: environmental impact and cost analysis
Abstract The use of concrete-filled tubular columns as part of structural systems has steadily increased throughout the years. The growing demand for structural elements of this nature is a direct result of the possibility to use various cross-section shapes that have increased strength, along with resistance to fire and other corrosive agents. The main obje

2. Comparison of minimal-flow sevoflurane versus desflurane anesthesia: randomized clinical trial
Abstract Background and objectives: Minimal-flow anesthesia provides various advantages, such as reduced environmental pollution, proper humidification and warming of anesthetic gases, and reduced costs. The aim of this study was to compare the cost-effectiveness of minimal-flow sevoflurane and desflurane anesthesia and their effects on hemodynamics, postop

3. The importance of education
Abstract The present research is dedicated to analyzing the addition of sawdust biomass, which is a carbonaceous raw material that may be used in coal blends for the production of metallurgical coke, preserving the required quality, with lower cost. The quality of metallurgical coke may be determined by the efficiency of its chemical, physical and thermal fu

4. Quality evaluation of metallurgical coke produced with sawdust and different mixtures of coal
Abstract The present research is dedicated to analyzing the addition of sawdust biomass, which is a carbonaceous raw material that may be used in coal blends for the production of metallurgical coke, preserving the required quality, with lower cost. The quality of metallurgical coke may be determined by the efficiency of its chemical, physical and thermal fu

6. Early intervention program by ICF model for babies of 4-18 months frequenting daycare center: protocol for clinical trial
Abstract Introduction: A daycare center is a long-term place for infants, which means that early intervention programs should be thought of in this environment. There are still many gaps regarding the best way of stimulation/intervention, duration and description of effects and controlled outcomes. Aim: The objective of this clinical trial is to propose

7. A simple spline finite strip for buckling analysis of composite cylindrical panel with cutout
Abstract In this study, a new sub-parametric strip element is developed to simulate the axially loaded composite cylindrical panel with arbitrary cutout. For this purpose, a code called SSFSM is developed in FORTRAN to analyze the buckling of panels. The first order shear deformation theory is used to form the strain-displacement relations. Spline and Lagran

8. Partial substitution of fishmeal with soybean protein-based diets for dourado Salminus brasiliensis
ABSTRACT Cost and environmental restrictions limit the use of fishmeal (FM) in aquafeeds and plant protein (PP) sources. Soybean by-products are important alternative; however, their antinutritional factors may reduce fish growth. This study evaluates the effect of FM substitution for PP (soybean meal and soy protein concentrate) in diets of dourado (Salmi

9. A sinusoidal equation as an alternative to classical growth functions to describe growth profiles in turkeys
ABSTRACT. Because of the relatively long growing cycle and the high cost of research into turkey production and nutrition, the potential benefits from modelling growth in this avian species are considerable. Though there are many studies aimed at evaluating animal growth models, the number of studies targeting growth models in turkeys is quite limited. In th

10. Developing a stepwise approach to simulate a hammer mill through the Whiten model - the adherence for a gold ore
Abstract Comminution represents a large portion of the capital and operating cost of a mineral processing plant. In 1983, Cohen estimated that comminution processes could account for 30% to 50% of the power consumption of the mill, and typically represents 50% of the operating costs of a mine. Therefore, its optimization is directly related to reduction of t

11. WATER-BASED EXERCISE AND RESISTANCE TRAINING IMPROVE COGNITION IN OLDER ADULTS
RESUMO Introdução: A prática de exercícios físicos tem sido associada à manutenção das habilidades físicas e redução do declínio cognitivo durante o envelhecimento, sendo considerada uma estratégia de prevenção primária de baixo custo, assim como tratamento não-farmacológico da disfunção cognitiva em idosos. Entretanto, a contribuição

12. Recommended Finite Element Formulations for the Analysis of Offshore Blast Walls in an Explosion
Abstract This study suggests relevant finite element (FE) formulations for the structural analysis of offshore blast walls subjected to blast loadings due to hydrocarbon explosions. The present blast wall model adopted from HSE (2003) consists of a corrugated panel and supporting members, and was modelled with shell, thick-shell, and solid element combinatio
