1. A study of burrow morphology in representative axiidean and gebiidean mud shrimps, from the Persian Gulf and Gulf of Oman, Iran
Mud shrimps (formerly Thalassinidea) are common burrow dwelling decapod crustaceans in the littoral zone of the Persian Gulf and Gulf of Oman. Their burrow morphology was investigated using foam casting methods. The present study shows that the burrow morphology in Upogebia carinicauda is not consistent and the recorded variations are based on habitat type a

2. Torsional force applied to the tibia of living lambs in an attempt to change the bone rotational axis
PURPOSE: To evaluate the effects of torsional force on the rotational axis of living lamb tibias.METHODS: An external fixator device was designed to apply rotation to the tibias of lambs. Once a week, the bone distal extremity was rotated 2º. After achieving ~20º of internal rotation, the turning was discontinued and the device was maintained in situ for o

3. Filogenia e biogeografia das espécies de actinote hübner, 1819 (Nymphalidae : Heliconinae) / Phylogeny and biogeography of species of actinote hübner, 1819 (Nymphalidae : Heliconinae)
Many aspects and details of the origin, evolution and biogeographical patterns of butterflies are not yet fully comprehended. The phylogenetic relationships among most butterfly groups remained unknown until recently. Phylogenetic studies have been based mainly on morphological characters of adults, although characters of immature stages had increased in use

4. Tratamento fungicida e qualidade de sementes de mamona / Fungicide treatment and quality of castor bean seeds
The rising interest in using biodiesel as an alternative energy source is turning some oleaginous crops, like castor bean (Ricinus communis L.), become very important. Although its importance, castor bean yields must have high quality seeds. There are no registered chemical products for castor bean crop; this study aimed to verify fungicide treatments in cas

5. SUPPORTING INTERACTION AND INTERFACE DESIGN AND EVALUATION / APOIANDO O PROJETO E AVALIAÇÃO DA INTERAÇÃO E DA INTERFACE: UM ESTUDO E UMA FERRAMENTA
Nowadays, with the growing popularity of the Internet and mobile devices, interactive systems have increasingly gained ground among different people, with different cultural backgrounds. However, the design of the interaction that takes place between the users and those systems is not properly supported by tools nor notations, turning the interactive experie

6. Análise psicofísica de medidas subjetivas de tempo em contexto rítmico / Psychophysical analysis of subjective measures of time in rhythmic context
Purpose: To study mechanisms that limit the accuracy of rhythm production and sensorimotor synchronization analyzing the variability in finger tapping tasks, be they spontaneous finger tapping, sensorimotor synchronization to external metronomes, or rhythm maintenance after turning off the external metronome. Methods: A total of 11 participants (mean age ±

7. Application of the Minimum Quantity Lubrication (MQL) technique in the plunge cylindrical grinding operation
Precision cylindrical grinding is used extensively in the manufacture of precision components in the metal-mechanical industry in general. Modern CNC grinding machines have improved this process with respect to the positioning and rigidity of the machine-workpiece-tool system, allowing the production of high precision parts with low dimensional tolerances. B

8. Internal turning for cylinder liners made of centrifuged gray cast iron / Torneamento interno de cilindros automotivos de ferro fundido cinzento centrifugado
This investigation describes and shows an unprecedented machining process to be used for manufacturing cylinder liners, which are very important parts used in aluminum engine blocks for automobiles. There are few known companies that manufacture this kind of component, and until now, all of them use a boring process to machine the internal diameter of the cy

9. Materiais e técnicas contemporâneas para controle de ruído aéreo em edifícios de escritórios: subsídios para especificações / Contemporaneous materials and techniques to air noise control on corporate edifices: specification foundations
Big cities have been taken the ground thought freeways and avenues, where constant and loud noise takes place. At theses ways, corporate edifices are also often established, so they naturally become exposed to the external noise interference, regardless the own internal facilities noising. The consequence is that people how work at these places are more pron

10. Evaluation through the mgnetic inspection of the superficial condition of steel bearing rings DIN 100Cr6 after hard and dry turning. / Avaliação através da inspeção magnética da condição superficial de anéis de rolamento de aço DIN 100Cr6 após torneamento duro a seco.
The present work presents information for the manufacturing of ball bearings components with higher limits of resistance to fatigue, enabling a longer useful life and also the optimization of the production of the pieces, making the usual and final process of grinding unnecessary, which would result in a costs reduction. The motivations of this study are the

11. Electric power system protection considering safety aspects of the communication network / Proteção de sistemas elétricos considerando aspectos de segurança da rede de comunicação
Modern world is more connected each day by all technological means available. This allows more people to communicate, turning the virtual communication road obligatory to the survival of small, medium and large companies, whether public or private. The great technological advance of the 20th century was the large use of the PCs (personal computer), usually c

12. Espelho ante espelho: a troca e a guerra entre o neopentecostalismo e os cultos afrobrasileiros em Salvador
For the last two decades, an important phenomenon of conflict has altered deeply the Brazilian religious scenario, questioning one of the main aspects of its official narratives, religious syncretism. In its recurrence in time and in its dissemination throughout the national territory, tensions between the neopentecostal evangelical denominations and afro-Br
