1. DEVELOPMENT AND OPTIMIZATION OF A SPECTROPHOTOMETRIC METHOD WITH CLOUD POINT EXTRACTION FOR DETERMINATION OF GADOLINIUM
This work describes a simple, sensible, and low-cost analytical method, based on cloud-point extraction (CPE) of the surfactant (1,1,3,3-Tetramethylbutyl)phenyl-polyethylene glycol (Triton X-114), for the efficient extraction and sensible determination of gadolinium after its complexation with 1-(2-pyridylazo)-2-naphthol (PAN) and subsequent determination by

2. ACCURACY OF GENETIC PARAMETERS ESTIMATION AND PREDICTION OF GENOTYPIC VALUES IN EUCALYPTUS USING DIFFERENT PLOT TYPES
ABSTRACT A suitable experimental design should control the environmental effect and be capable of discriminating genotypes. Two clonal tests of Eucalyptus were planted side by side in a randomized block design with the same 32 treatments under two different plot designs. The first trial was designed with five plants per plot (linear plot, LP) and six block r

3. Ganho de Conhecimento no Internato Médico em Psiquiatria Não Reduz Estigmatização dos Transtornos Mentais
RESUMO Introdução Considerando a prevalência dos transtornos mentais, é essencial que qualquer médico seja capaz de prestar assistência qualificada e humanizada a pessoas em sofrimento psíquico. No entanto, o usual estigma e a falta de conhecimento no manejo das doenças mentais por parte dos médicos podem representar uma barreira de acesso e inefic

4. Pós-tratamento de lixiviados coagulados por adsorção em resíduos da ostreicultura
RESUMO Neste trabalho, foi realizado o tratamento do lixiviado de um aterro urbano por meio de uma combinação dos processos de coagulação/floculação e adsorção. O lixiviado empregado foi coletado no aterro de resíduos sólidos urbanos da Muribeca (PE) e coagulado com cal. O objetivo foi avaliar o uso do pó de ostra como adsorvente. Os experimentos

5. Design of Three-Layer Antireflection Coating for High Reflection Index Lead Chalcogenide
Antireflection coatings (ARC), not only reduce the reflection of the incident radiation but also protect the surface from environmental degradations. In present study, three- layer design was theoretically calculated and experimentally realized on the surface of lead chalcogenide, which had high refractive characteristics. First the theoretical designs of th

6. Effects of miniemulsion operation conditions on the immobilization of BSA onto PMMA nanoparticles
Abstract Polymer nanoparticles have been widely used in many biomedical applications, constituting a major incentive for immobilization of proteins. Poly(methyl methacrylate) nanoparticles were synthesized through miniemulsion polymerizations and used as supports for bovine serum albumin immobilization. Particularly, the effects of surfactant type (anionic s

7. FORMULATION AND CHARACTERIZATION OF ULTRASOUND-ASSISTED NANOEMULSIONS CONTAINING PALM OIL (Elaeis guineensis Jacq) IN WATER
Abstract This study aimed to optimize ultrasound-assisted palm oil-in-water nanoemulsions. The influence of hydrophilic-lipophilic balance (HLB), oil and surfactants concentrations, ultrasound intensity and processing time were investigated by means of two experimental designs. Desirability profiles were applied to detect the optimal conditions for preparing

8. Delineamento experimental em Análise do Comportamento: discussão sobre o seu uso em intervenções educacionais inclusivas
Resumo A aplicação de intervenções educacionais inclusivas por agentes educacionais em estudantes da educação especial deveria ser sistematicamente avaliada, para garantir replicação futura dos procedimentos e resultados, a partir do uso de um delineamento experimental adequado à proposta. O objetivo foi analisar como pesquisas aplicadas podem contr

9. Analysis of the contribution of the block-soil contact in piled foundations
Abstract Geotechnical engineering has often been challenged by demands from technically and economically bold construction projects, such as that of tall buildings. The architectural requirements of these buildings have increased and concentrated the loads from structural systems without proportionally increasing plant area. New forms of using load capacity

10. Optimizing the Extraction of Anthocyanins from the Skin and Phenolic Compounds from the Seed of Jabuticaba Fruits (Myrciaria jabuticaba (Vell.) O. Berg) with Ternary Mixture Experimental Designs
Total phenolic compounds (TPC) extraction from the seed and total monomeric anthocyanins (TMA) extraction from the skin of “Sabará” jabuticaba were optimized with simplex lattice designs for solvent mixing, and the extraction time was optimized by univariate design. The optimum conditions for the extraction method were ethanol:water (60:40 v/v) solvent

11. Investigación de diseños de mezcla para producir Ultra High Performance Fiber Reinforced Concrete (UHPFRC) usando ANOVA
ABSTRACT An experimental study is presented to produce Ultra High Performance Fiber Reinforced Concrete (UHPFRC) including industrial waste in the mix, and determine the average compressive strength. The study includes factor arrangements to perform analysis of variance using ANOVA. The controllable factors were: (i) age of the sample; (ii) granulometry of t

12. Valorização de resíduos de ágata em argamassas e concretos: avaliação do ciclo de vida
RESUMO O uso de resíduos oriundos do processo de beneficiamento de ágata (pó de ágata) em argamassas e concretos de cimento Portland é viável tecnicamente por suas propriedades mecânicas e de durabilidade. Porém, não existem pesquisas que avaliem o perfil ambiental dos materiais produzidos. O presente estudo visa avaliar os impactos ambientais poten
