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. Flexure Based Energy Dissipating Device in Self-Centering Braces
Abstract Self-centering braces, in the current stage of development can accommodate large deformation and force levels. However, there is still a need for improvement of the energy dissipation mechanisms commonly incorporated in these braces. Yield based energy dissipation systems can overcome some of the problems faced with friction-based devices, such as s

3. Change in Functional Moderate Mitral Regurgitation after Aortic Valve Replacement
Abstract Objective: To evaluate the changes of the mitral valve geometrics and the degrees of moderate mitral regurgitation (MR) in patients undergoing aortic valve replacement (AVR) for aortic stenosis (AS). Methods: A retrospective analysis study of intraoperative transesophageal echocardiography (TEE) and postoperative transthoracic echocardiography (TT

4. Study on impact of fiber hybridization in material properties of engineered cementitious composites
ABSTRATO Compósito Cimentício Projetado (ECC) é um tipo de compósitos cimentícios reforçados com fibras de alto desempenho melhorados com bom comportamento de tração, compressão e flexão. O ECC é conhecido por seu comportamento de endurecimento de tensão sob tensão e tem sido cada vez mais aplicado na prática de engenharia. O processo de adicio

6. Study on elastoplastic coupling mechanics model of the milled mixture of sugar cane
Abstract At present, the phenomenon of elastoplastic coupling isn’t considered in establishing the mechanics model of the milled mixture of sugar cane. In order to describe elastoplastic coupling and yield characteristics, based on uniaxial confined compression tests and direct shear tests, the evolution of the elastic parameters of the solid fiber with v

7. Development of fast dissolving tablets of flurbiprofen by sublimation method and its in vitro evaluation
Flurbiprofen belongs to Biopharmaceutical Classification System (BCS) class II drugs which are poorly soluble in water. The objective of present research work was to prepare fast dissolving tablets of Flurbiprofen using varying concentrations of three different sublimating agents to improve the dissolution rate. Seven formulations were prepared containing di

8. The development and characterization of Propranolol Tablets using Tapioca starch as excipient
Abstract: Tapioca starch (TS) is produced from Cassaca roots and it is differentiated from other starches because it contains about 17–20% amylase and low amount of residual substances. Propranolol (POP) is a non-selective beta-adrenergic blocking agent and it is in the World Health Organization’s List of Essential Medicines. The aim of this work was to

9. Analysis of generation and characterization of construction and demolition waste on construction sites in the city of Recife, Brazil
ABSTRACT In order to planning the Construction and Demolition Waste (CDW) management approach on a construction site, it is necessary to have a prior knowledge of what is being generated (qualitative analysis), the quantity that is being generated (quantitative analysis), and what is the proper final destination assigned to this material. This article propos

10. MicroRNA-221 promotes cell proliferation, migration, and differentiation by regulation of ZFPM2 in osteoblasts
Bone fracture is a common medical condition, which may occur due to traumatic injury or disease-related conditions. Evidence suggests that microRNAs (miRNAs) can regulate osteoblast differentiation and function. In this study, we explored the effects and mechanism of miR-221 on the growth and migration of osteoblasts using MC3T3-E1 cells. The expression leve

11. Physical characterization of multiparticulate systems
ABSTRACT The search for new pharmaceutical dosage forms and different drug delivery systems already used in therapeutics is a global trend, serving as an opportunity to expand the portfolio for the pharmaceutical industry. In this context, multiparticulate systems, such as pellets, granules, and minitablets, represent an attractive alternative, given the ran

12. Preparation and physicochemical characterization of meloxicam orally fast disintegration tablet using its solid dispersion
ABSTRACT Meloxicam (MLX) is a non-steroidal, anti-inflammatory drug that is prescribed in the treatment of rheumatoid arthritis and osteoarthritis. MLX is practically insoluble in water and exhibits a slow onset of action. In this study, MLX solid dispersions (MLX SDs) were prepared to improve the water solubility of this poorly water-soluble drug. Then oral
