25. APPLICATION OF POLYCARBOXYLIC ACIDS AS BINDERS FOR TiO2 IMMOBILIZATION ON COTTON TEXTILES
ABSTRACT Immobilizing the photocatalyst on a support is an alternative solution to a critical issue in photocatalysis, which is the need for unit operations to remove the photocatalyst from the effluent. In this work, TiO2 was immobilized onto a cotton textile substrate by polycarboxylic acid binders (succinic and citric acids) using a solution deposition me

26. BIOTECHNOLOGICAL APPLICATION OF SURFACE MODIFIED CERIUM OXIDE NANOPARTICLES
ABSTRACT Re-engineering of chemical materials at the nanoscale level that employ modification and improvement in their physical and chemical properties has been constantly pursued for application in biomedical and biotechnology industries. Moreover, immobilization of catalysts on these bio/chemically modified nanomaterials improved the performance of enzymes

27. Temporomandibular joint function 10-15 years after mandibular setback surgery and six weeks of intermaxillary fixation
Abstract Intermaxillary fixation (IMF) is a classic method for immobilization of the mandible after mandibular fractures and corrective surgery. However, it has been suggested that IMF may be a risk for developing temporomandibular joint (TMJ)-related symptoms, especially when applied for longer periods. Objective: To evaluate the clinical function of TMJs

28. Como superar a cultura da imobilização física das parturientes? Resultados parciais de estudo de intervenção em São Paulo, SP, Brasil
Superar a cultura de imobilização física no trabalho de parto e no parto ainda é um desafio no Brasil. Este trabalho identificou facilitadores e obstáculos para a implementação de maior liberdade de posição, em projeto-piloto da Iniciativa Hospital Amigo da Mulher e da Criança numa maternidade do Sistema Único de Saúde (SUS) de São Paulo, Brasil

29. Hip Desarthrodesis - Report of Three Cases
Resumo A desartrodese de anca, isto é, a conversão da artrodese ou fusão óssea cirúrgica em uma artroplastia de substituição articular da anca, é uma intervenção difícil e desafiante, na medida em que é preciso reconstruir uma articulação perante uma consolidação óssea e uma imobilização muitas vezes de longa duração entre fêmur e acet�

30. Latissimus Dorsi Tendon Transfer using Tendinous Allograft for Irreparable Rotator Cuff Lesions: Surgical Technique
Resumo No contexto do tratamento cirúrgico dos pacientes jovens com lesões irreparáveis da porção posterossuperior do manguito rotador, a técnica mais usada é a transferência do tendão do grande dorsal para a porção superolateral do tubérculo maior, conforme descrita e preconizada por Gerber et al. Entretanto, duas características dessa técnica

31. Potassium chloride: impacts on soil microbial activity and nitrogen mineralization
RESUMO: O cloreto de potássio (KCl) é a fonte de potássio mais utilizada mundialmente e, devido ao uso contínuo desse fertilizante, pode ocorrer acúmulo de sais no solo e nas plantas. O excesso de íons desencadeia uma série de distúrbios fisiológicos, tornando-se um potencial biocida no solo. Objetivou-se avaliar o efeito da aplicação de doses de

32. Study of the parameters used in the encapsulation of commercial pectinase in calcium alginate and its effect on its catalytic activity
Abstract Despite the high catalytic properties of pectinases, the utilization of free enzymes always presents some hindrances such as low stability, a difficulty for product recovery and the impossibility of continuous use. Enzyme encapsulation is one of the methods used to overcome these limitations; however, some kind of effect is expected to occur on its

33. Polydimethylsiloxane as a Matrix for the Stabilization and Immobilization of Zero-Valent Iron Nanoparticles. Applications to Dehalogenation of Environmentally Deleterious Molecules
A wet-synthetic method is described to obtain magnetic, air-stable, zero-valent iron nanoparticles coated with an alkanedioic acid. The particles can be immobilized in an amino-substituted polysiloxane matrix to provide materials capable of dechlorinating, debrominating, and deiodinating a wide variety of halogenated organic molecules dissolved initially in

34. IMOBILIZAÇÃO DE COMPLEXO DE RUTÊNIO CONTENDO BASE DE SCHIFF NA UNIDADE METALOORGÂNICA UiO-67
Zirconium-based metal-organic framework, UiO-67, was synthesized and used as support for the immobilization of the [RuCl2(ENAPY)] (ENAPY = N,N'-bis(7-metyl-2-pyridylmethylene)-1,2-diiminoethane)). The immobilized system exhibited violet-blue color. The {UiO-67/[RuCl2(ENAPY)]} was characterized by cyclic voltammetry, X-ray diffraction, UV-Vis, FTIR and X-ray

35. Immobilization of the Magnetic Nanoparticles with Alkaline Protease Enzyme Produced by Enterococcus hirae and Pseudomonas aeruginosa Isolated from Dairy Effluents
ABSTRACT Protease is an enzyme which has a wide range of applications in various fields. Extracellular protease was produced from Pseudomonas aeruginosa and Enterococcus hirae which were isolated from the effluents of diary industries. Protease immobilized with super paramagnetic nanoparticles was characterized by DLS, XRD and TEM methods in relation to thei

36. Efficiency of decolorization of different dyes using fungal biomass immobilized on different solid supports
Abstract Different technologies may be used for decolorization of wastewater containing dyes. Among them, biological processes are the most promising because they seem to be environmentally safe. The aim of this study was to determine the efficiency of decolorization of two dyes belonging to different classes (azo and triphenylmethane dyes) by immobilized bi
