Estimating the capabilities, or inputs of production, that drive and constrain the economic development of urban areas has remained a challenging goal.We posit that capabilities are instantiated in the complexity Shooting Supplies and sophistication of urban activities, the know-how of individual workers, and the city-wide collective know-how.We de
Abstract Background Telomeric small RNAs related to PIWI-interacting RNAs (piRNAs) have been described in various eukaryotes; however, their role in germline-specific telomere function remains poorly understood.Using a Drosophila model, we performed an in-depth study of the biogenesis of telomeric piRNAs and their function in telomere homeostasis i
The strength of concrete is considered as the most basic and important material property in the design of reinforced concrete structures.The two standard methods (ASTMC39-03 and BS1881-part 116) for determining the compressive strength of concrete are the testing to failure of cylinder and cube specimens respectively.It has become a problem to use
This paper presents a solution for enhancement of aerodynamic efficiency for asymmetric airfoils.In order to increase the lift and reduce the drag forces for a Bed linen blade segment, a groove was created on its surface.There were carried out experiments consisting in the analysis of two asymmetric airfoil segments of the same type in the wind tun
