1. Assessing Water Erosion Processes in Degraded Area Using Unmanned Aerial Vehicle Imagery
ABSTRACT The use of Unmanned Aerial Vehicles (UAVs) and Structure from Motion (SfM) techniques can contribute to increase the accessibility, accuracy, and resolution of Digital Elevation Models (DEMs) used for soil erosion monitoring. This study aimed to evaluate the use of four DEMs obtained over a year to monitor erosion processes in an erosion-degraded ar

2. Optimized design of RC deep beams based on performance metrics applied to strut and tie model and in-plane stress conditions
Abstract Deep beams do not behave according to classical beam theory. The nonlinearity of strain distribution within these elements requires application of strut and tie models (STM) or other alternatives to evaluate the complex stress field. Although the design of these elements is a common task for structural engineers, limited research is found on assessi

3. Bioassay for Determining Persistence of the Herbicide Saflufenacil in an Oxisol
RESUMO: A persistência de um herbicida é definida como a habilidade para manter a integridade da molécula e suas propriedades químicas, físicas e fitotóxicas no ambiente onde ele foi aplicado. O conhecimento da persistência tem implicações tanto sobre a toxicidade gerada sobre espécies cultivadas em sucessão quanto sobre o período em que o herbic

4. Evaluating rumen fermentation kinetics and nutritive value of sunflower seed meal supplemented with acetonic extract of pomegranate peel using in vitro gas production technique
ABSTRACT. This study was conducted to investigate effects of supplementing different levels (0.0, 0.5 and 1.0% of buffered rumen fluid) of acetonic extract of pomegranate peel on rumen fermentation kinetics of sunflower seed meal (SFM), using in vitro gas production technique. The samples were incubated in syringes containing rumen liquor obtained from three

5. Vigor and mortality of citrus progenies with potential use as rootstocks
ABSTRACT: Rootstocks influence certain characteristics of the scion, such as vigor, fruit yield and quality, and tolerance to biotic and abiotic factors. In conventional citrus breeding programs, hybridization is the main method used for obtaining rootstock varieties. Between Sept and Oct 2006, controlled pollinations were carried out resulting in nine proge

6. Is there correlation between polymerization shrinkage, gap formation, and void in bulk fill composites? A μCT study
Abstract: This in vitro study aimed to evaluate the volume of polymerization shrinkage (VS), gap (VG), and void (VV) using computerized microtomography (μCT) in bulk fill resin composites and conventional class I restorations, and to establish a correlation between these factors. Class I cavities (4 x 5 x 4 mm), C-factor = 4.2, were performed on caries-free

7. A escala CR-10 de Borg é viável para quantificar a intensidade do exercício aeróbio em mulheres com síndrome fibromiálgica
RESUMO Pacientes com síndrome fibromiálgica (SFM) relatam elevados níveis de percepção subjetiva de esforço (PSE) em comparação com indivíduos saudáveis para a mesma intensidade de exercício; no entanto, a nosso conhecimento, nenhum estudo avaliou a PSE no limiar de anaerobiose ventilatório (LAV) para essa população. Este estudo buscou avaliar

8. Metabolizabilidade da energia de farinhas mistas contendo silagem de peixes para frangos de corte
RESUMO Objetivou-se com este trabalho determinar o valor nutricional e os valores de energia metabolizável aparente (EMA) e EMA corrigida para o balanço de nitrogênio (EMAn) de quatro farinhas mistas contendo silagem de resíduo de filetagem de tilápia para frangos de corte do tipo crescimento lento com 28 a 38 dias de idade. Analisou-se a composição f

9. Substitution of rumen degradable nitrogen with urea in sheep fed low quality Eragrostis curvula hay
ABSTRACT The aim of the present study was to determine whether sunflower meal (SFM), a highly rumen degradable protein (RDP) source, can be substituted with non-protein nitrogen (NPN, urea) without impacting negatively on intake, digestibility, rumen fermentation and microbial nitrogen (N) synthesis (MNS) in wethers consuming low quality Eragrostis curvula h

10. A modified method by differential adhesion for enrichment of bladder cancer stem cells
ABSTRACT Purpose: In a previous study the vaccine was effective against bladder cancer in a mouse model. However, a small portion of tumors regrew because the vaccine could not eliminate bladder cancer stem cells (CSCs). In this study, we showed a modified method for the isolation of bladder CSCs using a combination of differential adhesion method and serum

11. Sunflower Meal and Supplementation of an Enzyme Complex in Layer Diets
ABSTRACTThe objective of this experiment was to evaluate the performance of 64- to 79-wk-old laying hens fed diets supplemented with an enzyme complex (EC) and containing increasing sunflower meal (SFM) levels. A total of 384 Hy-Line Brown layers were distributed according to a randomized block design in a 4 × 2 factorial arrangement (four levels of SFM, an

12. Disfunção temporomandibular na síndrome da fibromialgia: comunicação breve
A síndrome da fibromialgia (SFM) é uma síndrome dolorosa crônica. A coexistência de uma condição dolorosa causada pela disfunção temporomandibular (DTM) e pela SFM tem sido frequentemente descrita por vários estudos. No entanto, a hipótese mais provável é que um conjunto de características da SFM pode levar ao aparecimento de sintomas de DTM e
