The important role of polygenic acetabular configuration and monogenic joint laxity has again been proved in the aetiology of congenital dislocation of the hip. According to the findings reported these two genetic predispositions seem to be unrelated. The time of diagnosis in accetabular dysplasia type and joint laxity type did not differ, thus the neonatal and late-diagnosed cases do not seem ...

Surface Acoustic Wave (SAW) devices, using interdigital electrodes, play a key role in today’s telecommunication systems and are widely used as electronic filters, resonators, delay lines, convolvers or wireless identification systems (ID tags). During the last three decades, demands set by the expansion of the telecommunication industry and many applications in sensor have resulted in the intr...

This paper studied the manufacturing process of Piezoelectric-on-Silicon (POS) substrate which integrates 128° Y – X Lithium niobate thin film and silicon wafer using Smart-Cut technology. The blistering exfoliation processes He as-implanted LN crystal under different annealing temperatures are observed by in-situ method. Unlike conventional polishing process, stripping mechanism is changed con...

A surface acoustic wave (SAW) formaldehyde gas sensor was fabricated on a 42° 75? ST-cut quartz substrate, with composite sensing layer of zeolitic imidazolate framework (ZIF)-8 polyethyleneimine (PEI)/bacterial cellulose (BC) nanofilms. The addition snowflake-like ZIF-8 structure the PEI/BC sensitive film significantly improves hydrophobicity SAW and increases its sensitivity to gas. It also r...

Abstract Traditional tree management is laborious and costly, thus this work aimed to study the performance of two different types frond cutting saws (reciprocating saw vibrating saw) examine on five date palm varieties. Four parameters were examined, including time for a single frond, power needed productivity expressed as tree/h, vibration conveyed worker’s hand. A field experiment was design...

This work aims at presenting, in a comprehensive manner, several approaches to model and simulate closed loop topologies using the classical Lagrangian formulation. One of great advantages approach is its simplicity easiness obtaining equations motion. However, critical aspect arises when mechanical systems include topologies, since process deriving motion becomes complex task. The key point pr...

a fissure was discovered extending upwards through the shaft of the tibia as far as the articular cartilage. It was accordingly f ound necessary to amputate at the knee joint. A broad anterior flap, and as long as possible, extending down, in fact, to the edge of the laceration, was dissected off", the joint was then opened and a short posterior flap cut through the muscles at the back. The joi...

“On a beautiful night in October 1978, in the Chesapeake Bay, two vessels sighted one another visually and on radar. On one of them, the Cost Guard cutter training vessel Cuyahoga, the captain (a chief warrant officer) saw the other ship up ahead as a small object on the radar, and visually he saw two lights, indicating that it was proceeding in the same direction as his own ship [Figure 1(t1),...

Abstract National cancer plans (NCPs) saw a strong push with the recommendation of European Commission from 2009, which called upon Member States to adopt NCPs or national strategies. This process resulted in rapid adoption NCPs. Joint Action EPAAC developed Guide for Quality Cancer Control Programmes support their preparation. Europe's Beating Plan poses new task and challenge need transpose i...

Analyses of joint moments are important in the study of human motion, and are crucial for our understanding of e.g. how and why ACL injuries occur. Such analyses may be affected by artifacts due to inconsistencies in the equations of motion when force and movement data are filtered with different cut-off frequencies. The purpose of this study was to quantify the effect of these artifacts, and c...
