In the process of coring in a high in-situ stress environment, rock core is damaged due to release, and discing prominent manifestation this damage. Pressure-preserved has no direct effect on stress, its influence release related drilling fluid pressure. Yet pressure was not considered most former numerical simulation studies discing. paper, discrete element method software PFC3D used conduct p...

OBJECTIVE The aim of this study was to determine the effect of trenched zirconia bar on the von Mises stress distribution of IPS -Empress II core ceramics. MATERIALS AND METHODS The three-dimensional model including a three-unit bridge from the second premolar to the second molar was designed. The model was reinforced with zirconia bar (ZB), zirconia bar with vertical trench (VZB) and zirconi...

This research deals with determination of the loading an open container during operating modes. The special feature this is its convex walls. engineering solution increases useful capacity a by 8% in comparison to that prototype. elastic elements bearing structure were introduced decrease dynamic loads. loads vertical plane dumped means dry friction forces between components cross bearers conta...

The maintenance of the ballast substructure is an important cost-driver for railway systems. problem that today’s condition monitoring methods are insufficient to collect detailed data on compaction and stress allocation inside bed. That makes it challenging improve technology organization. This study aimed investigate applicability ultrasound method analyzing state sand-soil relation between r...

INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY Unsteady Rotating MHD Free and forced Convection Flow in a Channel R.N Barik Department of Mathematics, Trident Academy of Technology, Infocity, Bhubaneswar-751024, Odisha, India [email protected] Abstract An analysis is made for transient, fully-developed MHD free and forced convection flow of a viscous, incompr...

This paper is focused on soil subsidence of small extend and amplitude caused by tunnel boring or the collapse of underground cavities, whether natural or man-made. The impact of the movements of the ground on existing structures is generally dramatic. It is therefore necessary to accurately predict these movements (settlements and horizontal extension or compression displacements). Even though...

Horizontal gene transfer (HGT) is believed to be a major source of genetic variation, particularly for prokaryotes. It is believed that horizontal gene transfer plays a major role in shaping bacterial genomes and is also believed to be responsible for the relatively rapid dissemination and acquisition of new, adaptive traits across bacterial strains. Despite the importance of horizontal gene tr...

BACKGROUND Ventilated patients with asymmetry of lung or chest wall mechanics may be vulnerable to differing lung stresses or strains dependent on body position. Our purpose was to examine transpulmonary pressure (P TP) and end-expiratory lung volume (functional residual capacity (FRC)) during body positioning changes in an animal model under the influence of positive end-expiratory pressure (P...

abstract : horizontal root fractures in permanent teeth are uncommon injuries among dental traumas. the principle of treating horizontal root fractures of permanent teeth is repositioning and fixation of fractured segment. diagnosis of tooth fractures based on radiographic findings and the fracture healing process are affected by factors before and after injury. the present case reports the tre...

This paper presents the results of an experimental study on behavior cold- formed steel shear wall panel (CFSSWP) with fibrocement panels as sheathing, when it is subjected in-plane deformations and flexural deformation under perpendicular monotonically increasing horizontal loads longest plane. A full-scale housing section was built three walls a ceiling using commonly used construction detail...
