We report a comprehensive scaling law and novel lift generation mechanisms relevant to the aerodynamic functions of structural flexibility in insect flight. Using a Navier-Stokes equation solver, fully coupled to a structural dynamics solver, we consider the hovering motion of a wing of insect size, in which the dynamics of fluid-structure interaction leads to passive wing rotation. Lift genera...

BACKGROUND AND OBJECTIVES The number of laparoscopic surgeries performed is increasing every year and in most cases the pneumoperitoneum method is used. One alternative is the abdominal wall lifting method and this study was undertaken to evaluate changes of functional residual capacity during the abdominal wall lift procedure. METHODS From January to April 2013, 20 patients underwent laparos...

in this paper the general relatively isotropic l -curvature finsler metrics are studied. it isshown that on constant relatively landsberg spaces, the concepts of weakly landsbergian, landsbergianand generalized landsbergian metrics are equivalent. some necessary conditions for a relativelyisotropic l -curvature finsler metric to be a riemannian metric are also found.

A systematic literature review and a meta-analysis of indirect sinus lift without the use of bone graft material was performed. A PubMed search was made from January 2005 to January 2012 with keywords: "sinus lift", "osteotome", "graft" and "maxillary sinus elevation". The inclusion criteria were: maxillary sinus lift technique with osteotomes with a minimum follow-up period of 5 months after s...

The Object of this paper is to design and analyze a Hysteresis modulation based sliding mode control (HMSMC) for positive output elementary super lift Luo converter (POESLLC), which is the start-of-the-art DC-DC converter. The positive output elementary super lift Luo converter performs the voltage conversion from positive source voltage to positive load voltage. This paper proposes a HMSMC cap...

OBJECTIVE To determine if there is any observable difference in the midface of patients who have undergone a deep-plane face-lift vs a standard superficial musculoaponeurotic system (SMAS) plication face-lift. DESIGN Preoperative and postoperative photographs of 25 patients undergoing each type of face-lift were rated by 3 independent and blinded observers. A 7-point scale was used to grade i...

in this paper, we study projective randers change and c-conformal change of p-reduciblemetrics. then we show that every p-reducible generalized landsberg metric of dimension n  2 must be alandsberg metric. this implies that on randers manifolds the notions of generalized landsberg metric andberwald metric are equivalent.

In this study, the effect of creation swirly flow and needle lift profile change on the behavior of the diesel fuel spray considered. To this end, two phase flow inside the diesel injector was simulated using the CFD. Solid works software has been used for geometry creation and AVL-Fire software has been used for meshing and simulating. Firstly, the liquid flow and spray characteristics of the ...

The lift station is becoming increasingly common as a component of the sewerage systems of Indiana. Cities and towns that have operated for years without the necessity of a lift station (other than one integral with sewage treatment plant) are finding it necessary to include a lift station in plans for extension of sewers. Those cities and towns which have not yet found it necessary to include ...

The Harvard community has made this article openly available. Please share how this access benefits you. Your story matters. Abstract Hydrodynamic lift forces offer a convenient way to manipulate particles in microfluidic applications, but there is little quantitative information on how non-inertial lift mechanisms act and compete with each other in the confined space of microfluidic channels. ...
