Foundations of structures which are subjected to uplift loading require anchoring systems to resist pullout loads. Such anchors can be broadly classified as gravity anchors, pile anchors and plate anchors. Plate anchors can be circular, square or strip in shape. The loading applied on plate anchors can be vertical, inclined or horizontal depending on the anchor orientation. In this study, vario...

Recent observations of helioseismic holography revealed that magnetic fields that are inclined relative to the line-of-sight direction could cause systematic variations in measured acoustic phase shifts (hereafter, “inclined magnetic field effect”), and that the presence of surface magnetic field may shift the phases and impair the coherence of acoustic waves (known as “showerglass effect”), th...

The film flow of a two-dimensional suspension of neutrally buoyant liquid drops down an inclined plane wall is investigated by numerical simulation in the limit of vanishing Reynolds numbers. The results show that well-separated and solitary drops migrate toward an equilibrium position located between the free surface and the wall, for a broad range of the fluid physical properties and flow con...

Rotational drilling was a revolution in drilling technology. It made the drilling process more efficient and faster and more depth of well could be achieved through rotation method. Besides all of its advantages, the rotation approach induced some problems like pipe sticking and downhole cleaning to the drilling procedure. Hole cleaning and reduction of torque and drag seems to be vital in incl...

Small mammals must negotiate terrains that consist of numerous substrates that vary in diameter, surface structure, rigidity and orientation. Most studies on mammals have focused on the effects of substrate diameter during horizontal locomotion, especially in small- to medium-sized primates and marsupials. Locomotion across sloped arboreal substrates, however, is poorly understood. Here, in ord...

  Spreading and coating of nano and micro droplets on solid surfaces is important in a wide variety of applications including plasma spray coating, ink jet printing, DNA synthesis and etc. In spraying processes, most of droplets collide obliquely to the surface. The purpose of this article is to study the distribution of nano and micro droplets spreading when droplets impact at an oblique a...

In this paper, first the validity of 3-D DDA is examined by comparing its solution for dynamic block displacement with analytical solution. Displacement of a single block on an inclined plane subjected to a dynamic loading is studied for analytical solution with respect to the frictional resistance offered by the inclined slope. 3-D DDA predicts accurately the analytical displacements. The modi...

OBJECTIVES To study the attitudes of health care staff in four postcommunist countries towards taking gifts from their clients--and their confessed experience of actually taking such gifts. DESIGN Survey questionnaire administered to officials including health care staff, supplemented by focus-group discussions with the general public. SETTING Ukraine, Bulgaria, Slovakia and the Czech Repub...
