this study was conducted to investigate the effects of planting date, foliar application of benomyl fungicide and potassium silicate in improving the quality of soybean (cv. williams) seed in gorgan during 2011 and 2012. in the first year (2011), the experimental treatments were including planting dates (april 20, may 13, june 3, june 29 and july 22) and foliar application of benomyl fungicide ...

We developed a fabrication method and a liquid filling method for a nano chemical reactor that used Y-shaped nanochannels specially designed for mixing and reacting. In order to reduce the pressure loss and to utilize the characteristics of the nanochannel, inlet microchannels were fabricated just beside the nanochannels. We investigated an initial liquid filling method into the nanochannels th...

Chest tube is a flexible plastic tube used to discharge secretion in the cavity between the lungs and chest named pleural cavity. Normally, there is a small amount of fluid in the cavity between the lungs and chest; This fluid helps the movement of lungs during breathing without abrasion. Entrance of bit of air, blood or pus because injury in the pleural cavity can prevent the lungs from fully ...

The Spectrum adjustable saline implant is optimal for prepectoral breast reconstruction as it can be placed virtually empty and thus flat, applying no pressure on the overlying skin flap. However, when saline is added, it tends to pool at the bottom of the implant resulting in its uneven surface and rippling. Air filling results in the uniform distribution within the implant shell and smooth ev...

We hypothesized that congenital diaphragmatic hernia (CDH) may decrease distal air space fluid absorption due to immaturity of alveolar epithelial cells from a loss of the normal epithelial Na+ transport, as assessed by amiloride and epithelial Na+ channel (ENaC) and Na-K-ATPase expression, as well as failure to respond to endogenous epinephrine as assessed by propranolol. Timed-pregnant dams w...

BACKGROUND AND PURPOSE No prior report has comprehensively discussed the intravertebral vacuum cleft sign and the fluid sign on MR images of vertebral osteonecrosis. The purpose of this study was to investigate MR images of osteonecrotic vertebral bodies and adjacent intervertebral disks and vertebral bodies. METHODS We retrospectively reviewed MR images of patients with vertebral osteonecros...

This paper investigates an original aspect in the study of longitudinal dynamics of trains submitted to braking actions: the influence of application time admitted ranges on in-train forces. Basic theoretical aspects are outlined and experiments were carried out in order to accurately determine the filling characteristics of brake cylinders. These were implemented in an original simulation prog...

dense medium cyclone is a high capacity device that is widely used in coal preparation. it is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in dmcs complex. in this article the flow pattern simulation of dmc is performed with computational fluid dynamics and fluent...

Computational Fluid Dynamics (CFD) is a computational technology that enables researchers to study the dynamics of things that flow. By using CFD, it is possible to build a computational model that represents a system under study. It not only predicts fluid flow behavior, but also the transfer of heat, mass, phase change, chemical reaction, mechanical movement, and stress or deformation of ...
