o bjectives: the aim of the present randomized clinical trial was to evaluate marginal bone loss around two types of implants modified at the neck area: nobel active and nobel replace groovy, both manufactured by nobel biocare. materials and methods: a total of 25 nobel active and 21 nobel replace groovy implants were included in the present study. the implants were placed based on the relevant...

low calorie diets are always difficult for obese subjects to follow and lead to metabolic and behavioral adaptation. therefore, we evaluated the effect of caffeine treatment with calorie shifting diet (csd) on weight loss. female subjects (n=98; bmi≥25) completed 4-weeks control diet, 6-weeks csd (3 repeated phases; each 2-weeks) and 4-weeks follow-up diet, with or without caffeine treatment (5...

The paper presents the effect of using cashew nut shell liquid (CNSL), a low-priced agro by-product and renewable resource, to treat coir geotextiles. Large-scale direct shear tests were performed on sands reinforced with untreated treated geotextiles at different normal stresses (50 kPa, 100 150 kPa). Sands three particle sizes (coarse, medium, fine) used for study. strength parameters soil sa...

The article is devoted todevelopment of afunctioning algorithm the control systemof phase-shifting devices in double-circuit overhead power lines, as well to formulation main tasks this system. Based on these, functional schemes for controllingphase-shifting were developed.The developed system will allow, through use transformers, which belong flexible alternating currenttransmission (FACTS)tec...

Previous research on the multi-beam system for fifth generation (5G) application has shown that number of feed elements a lens antenna at mobile base station is increasing due to massive MIMO requirements. The design array circuits 5G systems will be more complicated feeding structure, which consists power dividers and phase shifters, thus contributing higher losses. fabrication process also be...

Integral and angle resolved thermal desorption spectroscopies were used to study methanol adsorption and oxidation on clean and oxygen covered Cu(110) surfaces. Special emphasis was put on the Cu-CuO stripe phase, which forms when the Cu(110) surface is covered with 0.25 ML of oxygen. In the temperature regime between 200 and 300 K associative desorption of methanol and water takes place, showi...

Little is known about the patterns of muscle activation that subserve arm movement in three-dimensional space. In this study, activation patterns of seven arm muscles were related to the spatial direction of human arm movement. Twenty movement directions defined two orthogonal vertical planes in space. The arm movements were moderately paced; each movement lasted approximately 500 msec. New tec...

Gil Kalai introduced the shifting-theoretic upper bound relation to characterize the f -vectors of Gorenstein* complexes (or homology spheres) by using algebraic shifting. In the present paper, we study the shifting-theoretic upper bound relation. First, we will study the relation between exterior algebraic shifting and combinatorial shifting. Second, by using the relation above, we will prove ...
