the aim of the present study was to investigate the influence of nozzle configurations on spray drift and explain the influences using several atomization characteristics (length of spray sheet, spray angle, velocity distribution of flow field, fluctuation of velocity, and droplet size). nozzles manufactured by one company (lechler gmbh, germany) were tested by spraying local tap water in a win...

There is considerable interest in the potential relationship between postoperative endophthalmitis and clear corneal tunnel incisions for cataract surgery. Earlier work from Ernest et al. clearly demonstrated that incisions that are square in surface architecture are significantly more resistant to deformation and leakage than those that are rectangular. The purpose of this preliminary investig...

Background: Cubital tunnel syndrome, a neuropathy of ulnar nerve, is the second most common entrapping syndrome in the upper limb surpassing carpal tunnel syndrome. This syndrome arises from a high pressure decompressing the nerve for a long time. Patients with cubital tunnel syndrome show numbness in the ring and small fingers. The aim of this study was to evaluate the etiology of cubital tunn...

BACKGROUND Caffeine intake has been suggested to be associated with the risk of hypertension. Less is known about the associations of caffeine intake on maternal cardiovascular adaptations during pregnancy. We examined the associations of caffeine intake in different trimesters of pregnancy with repeatedly measured blood pressure and the risks of pregnancy-induced hypertension and pre-eclampsia...

Because of the particularity of the environment in the tunnel, the rational tunnel illumination system should be developed, so as to optimize the tunnel environment. Considering the high cost of traditional tunnel illumination system with high-pressure sodium (HPS) lamps as well as the effect of a single light source on tunnel entrance, the energy-saving illumination system with HPS lamps and L...

It has been reported that calcium intake may effectively modulate the expression of hypertension affected by sodium. The present study extends our previous analysis of this calcium-sodium interaction, additionally demonstrating that calcium, sodium, and alcohol intake further contribute to both systolic and diastolic blood pressures in normotensive subjects. Calcium intake was related to lower ...

This article investigates and presents a case study on the Beijing Subway Line 12 excavation beneath existing Qinghuayuan Tunnel. The composite pre-reinforcement technique was used in conjunction with shallow tunneling method to control distortion of large-diameter tunnel. When building twin tunnels underneath, this strategy considerably decreased impact To systematically mechanical response tu...

PURPOSE The purpose of this study was to compare four graft-tunnel angles (GTA), the femoral GTA formed by three different femoral tunneling techniques (the outside-in, a modified inside-out technique in the posterior sag position with knee hyperflexion, and the conventional inside-out technique) and the tibia GTA in 3-dimensional (3D) knee flexion models, as well as to examine the influence of...

the objective of this work was to develop a new design of an intake manifold through a 1d simulation. it is quite familiar that a duly designed intake manifold is essential for the optimal performance of an internal combustion engine. air flow inside the intake manifold is one of the important factors, which governs the engine performance and emissions. hence the flow phenomenon inside the inta...
