The interaction between nucleotides and carbon nanotubes (CNTs) is a subjectof many investigations for treating diseases but there are many questions in this field thatremain unanswered. Because of experimental methods involve assumptions andinterpretation besides limitations, there are many problems that the best study for them isusing theoretical study. Consequently, t...

Three experiments explore how American (N = 102) and Egyptian (N = 73) preschoolers’ inferences about expertise are affected by an expert’s gender and occupation. Children viewed a nurse and a car mechanic in a gender stereotypical (female nurse, male mechanic) or counterstereotypical (female mechanic, male nurse) presentation and indicated who would know more about profession-related informati...

This study documents age trends, interrelations, and correlates of intellectual abilities in old and very old age (70-103 years) from the Berlin Aging Study (N = 516). Fourteen tests were used to assess 5 abilities: reasoning, memory, and perceptual speed from the mechanic (broad fluid) domain and knowledge and fluency from the pragmatic (broad crystallized) domain. Intellectual abilities had n...

Results He had Type II A aortic dissection with intimal tear at proximal region of the right coronary ostium. Mechanic aortic valve was normal function. Ascending aorta was replaced by using 26 mm Dacron tube graft between annulus of previous mechanic aortic valve and distal ascending aort by using hypothermic circulatory arrest and antegrade selective cerebral perfusion. An 8 mm dacron tube gr...

Since the outbreak of SAR-CoV-2 infections in Wuhan (China), researched communication is on race to investigate specific antiviral drug for Covid-19 treatment. 3CLpro main protease chosen as a protein target because its high value preventing viral replications. In this study, we hereby aim clarify efficiency Penciclovir inhibiting mechanic SAR-CoV-2. Using docking simulation and molecular dynam...

Binding of curcumin, naproxen, and ibuprofen to Aβ1-40 peptide and its fibrils is studied by docking method and all-atom molecular dynamics simulations. The Gromos96 43a1 force field and simple point charge model of water have been used for molecular dynamics simulations. It is shown that if the receptor is a monomer then naproxen and ibuprofen are bound to the same place that is different from...

We review recent progresses in the theoretical studies on the structural, cohesive, mechanic and thermodynamic aspects of interfaces in solids. The technological developments for these studies are reviewed at first. In the next, we summarize the new achievements in the studies on the cohesive and structural properties of metal/metal, ceramic/metal and semiconductor interfaces by ab initio compu...

Level creation is a creative game-play exercise that resembles problem-posing, and has shown to be engaging and helpful for players to learn about the game’s core mechanic. However, in user-authoring environments, users often create levels without considering the game’s objective, or with entirely different objectives in mind, resulting in levels which fail to afford the core gameplay mechanic....

Cognitive gameplay—the cognitive dimension of a player’s experience—emerges from the interaction between a player and a game. While its design requires careful consideration, cognitive gameplay can be designed only indirectly via the design of game components. In this paper, we focus on one such component—the core mechanic—which binds a player and game together through the performance of essent...
