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...

Spontaneous imbibition in an angular tube with corner films is a fundamental problem many scientific and engineering processes. In this study, modified interacting capillary bundle model developed to describe the liquid dynamics square films. The decomposed into several subcapillaries local pressure each subcapillary derived based on specific shape of its meniscus. conductance calculated using ...

We study subgroups of SL ( 3 , R ) ⋉ $\mathrm{SL}(3,\mathbb {R})\ltimes \mathbb {R}^3$ obtained by adding a translation part to the holonomy finite-volume convex projective surface. Under natural condition on translations added peripheral parabolic elements, we show that affine action group $\mathbb has domains discontinuity which are regular, generalizing result Mess for globally hyperbolic fl...

Waste heat recovery is very important, because not only it reduces the expenditure of heat generation, but also it is of high priority in environmental consideration, such as reduction in greenhouse gases. One of the devices is used in waste heat recovery is heat pipe heat exchanger.Anexperimental research has been carried out to investigate the hydrodynamic and thermal performance of a gas...

This paper presents a three-dimensional numerical and experimental geometric optimization study to maximize the total heat transfer rate between a bundle of finned tubes in a given volume and external flow, for staggered arrangements of circular and elliptic tubes. Experimental results were obtained for circular and elliptic configurations with twelve tubes, starting with an equilateral triangl...

Reaction calorimetry of flow processes is important for scale-up and safety in chemistry. Due to the increasing number processes, corresponding calorimeters are required as an alternative or addition high-precision batch calorimeters. In this work, a milli-scale isoperibol continuous calorimeter was used measure heat reaction based on elaborated transfer model. This allows without calibration. ...

the detailed anatomy and histology of the atrioventricular bundle (avb) was studied in 10 adult cats (5 males and 5 females). the trunk of the atrioventricular bundle was a direct continuation of the atrioventricular node (avn) with no sharp line of demarcation between node and the bundle. the avb of the male cats measured 6.24 mm in length, 0.27 mm in width and 0.65 mm in thickness, while in t...

Introduction CRT is an effective treatment for patients with heart failure and intraventricular conduction delay. However, clinical non-response rates remain unacceptably high; emphasizing the need for improved selection criteria. Central to the underlying mechanism of resynchronization is the relationship between mechanical and electrical activation. The purpose of this study was to demonstrat...
