A tube graph is a mathematical entity that can be used for modelling architectural designs of software systems. It consists of a tree (representing containment) with a set of edges called tubes (representing dependencies) between the tree's vertices (representing components). Tubes, for example, can model the import relation at the module level and the use dependency relation at the subsystem l...

Flowering plants possess specialized extracellular matrices in the female organs of the flower that support pollen tube growth and sperm cell transfer along the transmitting tract of the gynoecium. Transport of the pollen tube cell and the sperm cells involves a cell adhesion and migration event in species such as lily that possess a transmitting tract epidermis in the stigma, style, and ovary....

Blood collection devices interact with blood to alter blood composition, serum, or plasma fractions and in some cases adversely affect laboratory tests. Vascular access devices may release coating substances and exert shear forces that lyse cells. Blood-dissolving tube additives can affect blood constituent stability and analytical systems. Blood tube stoppers, stopper lubricants, tube walls, s...

The quark confinement in QCD is achieved by concentration of the chromoelectric field between quark-antiquark pair into a flux tube, which gives rise to linear potential. We study structure tube created static pure gauge SU(3) theory, using lattice Monte-Carlo simulations. calculate spatial distribution all three components and perform “zero curl subtraction” procedure obtain nonperturbative pa...

the current study conducted a finite element (fe) and experimental investigation on tubular channel angular pressing as a noble severe plastic deformation technique for producing ultrafine grained and nanostructure tubular components. to examine the effects of the tcap process on the strain distribution and deformation behavior, fe simulations were employed. the fe results demonstrated that equ...

The focus of this work is the modeling and performance comparison of different models of pulse tube refrigerators, namely, the Orifice Pulse Tube Refrigerator (OPTR) and the Inertancetube Pulse Tube Refrigerator (IPTR) with both in-line as well as coaxial configurations. A detailed analysis of the flow and heat transfer in various components of the above mentioned models under oscillating flow ...

objective the purpose of this study was to assess the frequency of complications of endotracheal intubation (eti) in neonates. methods the newborns that were admitted and needed urgent or semi-urgent intubation were enrolled in this study over a 1 year period. route for intubation in all cases were orotracheal. cases were not routinely sedated or paralyzed. the patients were clinically and radi...

background and purpose: inserting a nasogastric tube, though a common clinical procedure with widespread use for critically ill patients, can produce unexpected complications so that tube misplacement into the lungs is a potential complication with serious consequences. the reliability of common bedside methods to differentiate between pulmonary and gastric placement has not been acceptable. th...

Kunshan Xintiandi Super Tall Building is 142 meters high, with 3 floors underground and 31 above ground. Its structural system composed of concrete-filled steel tube frame core tube. The elastoplastic time-history analysis the building was carried out by using PKPM-SAWS to analyze overall index whole structure under large earthquake, mechanical performance key components earthquake analyzed, lo...

Abstract In this study, based on the energy balance for different components of a double-layered vacuum-tube solar collector with U-tube, thermal performance unit is investigated separately using an analytical and quasi-dynamic method. The model used in study determines temperature distribution longitudinal radial directions. research, effects physical parameters heat transfer including size co...
