2. Experimental Tests on Bending Behavior of Profiled Steel Sheeting Dry Board Composite Floor with Geopolymer Concrete Infill
Abstract Profiled Steel Sheet Dry Board (PSSDB) system is a lightweight composite structure comprises Profiled Steel Sheeting and Dry Board connected by self-drilling and self-tapping screws. This study introduced geopolymer concrete, an eco-friendly material without cement content as an infill material in the PSSDB floor system to highlight its effect onto

3. Efeito da calagem e adubacao da seringueira no estado nutricional e producao de borracha seca.
Foram avaliados os efeitos da calagem e da adubação NPK no estado nutricional e na produção de borracha seca do clone RRIM 600. Utilizou-se o delineamento de blocos casualizados, com quatro repetições, em parcelas subdivididas. Nas parcelas foram testados duas testemunhas (sem adubação e sem calagem; sem adubação e com calagem), e seis tratamentos

4. Caracterização de três seringais manejados em terra firme, várzea e terra preta de índio no médio Amazonas
Seeking technical information to subsidize strategies to develop heveaculture in the Amazon state, a team of researchers of the National Institute of Amazon Research started in 2008 a descriptive research in rubber plantations in the Middle Amazon region, located in floodplain, in terra firme (TF) and indian black earth (TPI). In these areas we did: phytosoc

5. Experimental and theoretical study on workpiece temperature when tapping hardened AISI H13 using different cooling systems
Tapping operations on hardened steels have always been a great challenge. Dry machining and two cooling systems were used when tapping hardened AISI H13 (53 HRC). Embedded thermocouples were used for temperature measurement close to the thread diameter in the radial and axial direction. A FEA model was used to evaluate the heat "Q", and coefficient of convec

6. Avaliação de clones de seringueira (Hevea spp.) em Piracicaba-SP / Rubber tree (Hevea spp.) clones evaluation in Piracicaba - SP
Piracicaba-SP is on the extreme southern region suitable for rubber planting in Brazil, with little information on the performance of clones under its environmental conditions. The performance of growth and yield of ten rubber tree clones (Hevea spp.) were evaluated. The studied clones were CATI 21, IAC 15, IAN 873, GT 1, PB 235, PB, 252, PR 107, PR 261, RRI

7. Modelo para previsão da condição térmica de panelas de aciaria
Temperature control during the whole steelmaking process has a great importance to achieve the quality and productivity requirements demanded nowadays.At Gerdau Açominas steelplant, the temperature control of liquid steel from tapping up to the solidification in the caster has been widely studied. Due to the long casting times, a lack of control of the stee

8. InvestigaÃÃo do comportamento de ferramentas de aÃo-rÃpido no processo de rosqueamento interno em alta velocidade de corte / Investigation of the behaviour of high speed steel tools in tapping operation at high speed cutting
The main goal of this work is the evaluation of the performance of high-speed steel (HSS) taps when machining grey cast iron at high cutting speeds in dry conditions and when using MQL (minimal quantity of lubrication). The performance of four types of high speed steel with and without coating was investigated. They are: conventional HSS; HSS with addition o

9. Ensaios mecânicos e estudo histológico da interface dos implantes vertebrais / Mechanical and histological studies of the vertebral screw interface
Spine surgery has developed a lot in the last years because of the evolution of the fixation system. The behavior of a screw in the bone is still unknown in many ways. Because the screw is the anchor of sustentation, this work tries to find the answers involving the pedicle screw fixation. To reach this objective we developed this work based on mechanical an

10. Periodo de silencio eletromiografico, duração do ato e do ciclo mastigatorio em individuos com fissura labio-palatina
The purpose of the present study was to analyse the neuromuscular function of the stomatognathic system in subjects with cleft lip and palate and marked occlusal dysfunction. Electromyographic activity was recorded by a two channel-eletromyograph (DISA 1500 EMG- System). The duration of the EMG silent period, elicited by chin tapping as well as by voluntary

11. Avaliação ecofisiologica de seringueiras (Hevea brasilienses Muell. Arg.), submetidas a diferentes intensidades de sangria, em ambientes contrastantes do Estado de São Paulo
Aiming to contribute to the adaptation of rubber tree tapping system to contrasting environments found in the State of São Paulo, Brazil, a research program was carried-out to assess environmental and plant variables, as well as physiological parameters related to relax production. The experimental areas were located in Registro, Ribeira Valley region, and

12. Is tapping jet nebulisers worthwhile?
An in vitro system was used to study the effect of tapping a jet nebuliser on the dose delivered to patients. Using a 2 ml fill, effective drug delivery had ceased by 3 minutes but a further 38% was delivered to the filter by 5 minutes if the chamber was tapped.
