1. Royal jelly production in Africanized colonies with selected queens, use of Chinese model cups and supplementation
ABSTRACT. This research was carried out to evaluate the royal jelly production in two trials. In Trial I, three genotypes of Africanized honeybees (Apis mellifera L.) were submitted to royal jelly production with two types of cups of different size and volume (conventional and Chinese model) and two types of supplements (commercial and formulated). A total o

2. Phylogenetic diagnosis and expanded description of the genus Mazarunia Kullander, 1990 (Teleostei: Cichlidae) from the upper Mazaruni River, Guyana, with description of two new species
We expand the description of the genus Mazarunia Kullander, 1990, explore morphological diagnostic characters for the genus and for its sister-group relationship with Guianacara Kullander & Nijssen, 1989 in a phylogenetic context, expand the description of M. mazarunii and describe two new species. Mazarunia can be diagnosed by the combination of numerous an

3. Estimativa de um índice de estresse hídrico para a cultura da cana-de-açúcar com base na temperatura foliar / Estimating of crop water stress index to sugarcane based on the canopy temperature
The objective of this work was to evaluate the behavior of leaf temperature and transpiration of sugarcane under different matric and meteorological conditions to estimate a crop water stress index (IEHC), which can be applied in irrigation management and estimates of productivity. Because of the need to apply water stress to plants, the experiment was condu

4. A general study of commercially pure Ti subjected to severe plastic deformation: microstructure, strength and corrosion resistance
Bars of Titanium Grade 2 were subjected to deformation by Equal Channel Angular Pressing, both at room temperature and at 300°C. Additionally, some specimens were cold rolled up to 70% reduction. From tensile tests, data such as yield, maximum strength, elongation and area reduction were obtained. Results show that the best strength - ductility combination

5. Aprimoramento de formulação do MEF para barra geral laminada tridimensional pela consideração da cinemática de empenamento para seção qualquer / An improved finite element formulation for the analysis of general three-dimensional laminated bars with consideration of warping for any cross-section
In the present work an improved finite element formulation for the analysis of three-dimensional laminated bars is presented. The improvement is made by introducing the warping mode into the previous model that follows a general Reissner-Timoshenko kinematics hypotesis. In order to do so, a two-dimensional code is developed, based on Saint Venants torsion pr

6. Barras de cereais com amnÃndoas de chichÃ, sapucaia e castanha-do-gurguÃia, complementadas com casca de abacaxi / the cereal bars from almonds to chichÃ, sapucaia and chestnut-of-gurguÃia, supplemented with pineapple bark.
The trend of consumption of healthy food, innovative and practical has led to growth increasing in recent years the market for the cereal bars. The cereal bars are formed by grain cereals, processed and clusters, and they can be incorporated different ingredients, such as integral cereals, dehydrated fruit or crystallized fruit, almonds and sugars. There are

7. Perfis pultrudados de plástico reforçado com fibra de vidro aplicados à estrutura de um banco de capacitores de subestação de energia elétrica
In this work, an alternative capacitor bank framed structure was designed using glass fiber reinforced polymer (GFRP) pultruded bars. A finite element model was developed to simulate the structure static behavior and stability. Material properties were evaluated by a characterization test program. A prototype of the structure was built, instrumented and test

8. Ergonomic analisys of strength training equipment: usabilitys evaluation of dispositives to adjust some products of brazilian marks / Análise ergonômica do design de equipamentos para musculação: avaliação da usabilidade dos dispositivos de ajustes de alguns produtos de marcas brasileiras
The use of equipment for strength training has greatly increased with the popularization of gymnastic academies and strength training practice. Such equipments were originally used for athletic training, but with the advances of the studies in medicine and the increase in the populations sedentariness, this type of apparel came to be used by the general publ

9. Controle da Resposta Dinâmica de um Passarela de Pedestres da Cidade de Brasília com a Utilização de Amortecedores de Massa Sintonizados / Vibration control of a footbridge in the city of Brasilia using multiple tuned mass dampers (AMSM)
Advanced constructive technologies and the use of high resistance materials made possible the design of slender and flexible structures, which present less strength and damping. These structures are more sensitive to vibrations in low frequencies, characteristic of footbridges. The loads produced by human movements, mathematically represented by periodic fun

10. Análise não linear física de placas e cascas anisotrópicas laminadas acopladas ou não com meio contínuo tridimensional viscoelástico através da combinação entre o MEC e o MEF / Physical non-linear analysis of anisotropic laminated plates and shells coupled or not with three-dimensional viscoelastic medium by BEM/FEM coupling
This work presents an anisotropic laminated stiffened shell formulation, considering physical non-linearity with non-associative law, coupled to viscoelastic three-dimensional continuum medium. Plane triangular finite elements with cubic approximation for nodal variables are developed to model the shell. Bar elements with the same approximation are derived f

12. EXPERIMENTAL STUDY ON THE BEHAVIOR OF COMPOSITE COLUMNS SUBJECTED TO COMPRESSION AND BENDING / ESTUDO EXPERIMENTAL DO COMPORTAMENTO DE PILARES MISTOS SUJEITOS A FLEXO-COMPRESSÃO
Composite columns are a structural members subjected to compression and bending, made of concrete and structural steel. One particular type of composite column consists of rectangular steel hollow sections completely filled with concrete and reinforcing bars, which is the type of column considered in this work. One of the advantages of this column is the con
