For infants with high arched palate, feeding is one of the most immediate challenges faced by parents and caretakers. General suggestions for feeding in infants with cleft palate may be adapted to infants with high arched palate. These include oral feeding facilitation techniques and special feeding tools. Here we present a newborn with a high arched palate and serious feeding problems who was ...

Purpose: to study in cadaver knees the position of the tibial tunnel in anterior cruciate ligament (ACL) reconstruction using the 65° Howell guide. Type of study: controlled laboratory study in vitro Methods: 21 fresh-frozen cadaver knees were employed. The ACL was resected and its tibial attachment was demarcated. To drill the guide wire we employed the Howell 65 degrees tibial guide which ref...

When sailing downwind with a spinnaker, the “verge of curling” is one common recommendations that sailors follow for efficient sailing. Wind tunnel experiments on spinnaker models conducted by Aubin et al. (2017) in Twisted Flow Tunnel Yacht Research Unit University Auckland have shown curling can be related to better performance at Apparent Angle ≥ 100°. In present article, we will focus aerod...

When the planing hull is sailing at high speed, proportion of air resistance to total increases significantly. Therefore, by studying aerodynamic characteristics shape, we can analyze influence shape on performance hull, and find a method reduce resistance. The research took trimaran as object, completed wind tunnel test, established numerical simulation solving RANS equation combining k-ε turb...

Original scientific paper With the increase in mining depths and the occurrence of worsening conditions, deep, large-scale and rapid mining may lead to more complicated dynamic features for tunnels, making them vulnerable to dynamic disasters such as rock bursts and coal/gas outbursts with subsequent heavy damage and casualties. A three-dimensional structural mechanics model for deep stopes was...

Abstract Tunnel boring machine (TBM) operational data is mostly analysed with respect to that was recorded during the advance of TBM. Focusing on standstills a gripper TBM, we analyse rock loads were passively in cylinders small roof support shield. These are situated beneath TBM’s shield – extending it against mass non-advance periods. Equipped pressure sensors, they enable unique opportunity ...

The squat lobster Munida rugosa has an unusual chela dimorphism exhibited mainly by large males. Some individuals have 'arched' chelae in which there is a gap between the dactylus and the pollex when closed, and others have a 'straight' morphology in which the dactylus and pollex oppose along most of their length. Geometric morphometric analysis indicated that, compared with males, the arched m...

The paper presents the results of a comprehensive wind tunnel study dedicated to addressing effects underneath array clearance on loading roof-mounted solar panels. Indeed, has crucial influence in many respects ranging from its consideration modeling impact structural safety. A set atmospheric experiments was carried out three configurations multipanel mounted flat roof immersed simulated flow...
