The confidence in and reliability of science and engineering research is truly invaluable and especially so at the National Science Foundation (NSF). Although outright fraud or falsification in science is rare, a number of factors can compromise the reproducibility of published studies in science and serving the public interest requires guarding against them. “Reproducibility”, “replicability” ...

Abstract High levels of reliability and high security are the basic characteristics and requirements of railway signal systems. So, reliability, availability and maintainability (RAM) are necessarily analyzed before the computer interlocking system will be adopted. The All-electronic Computer Interlocking System, which is a new kind of interlocking system, still needs to analyze its RAM before ...

OBJECTIVE To determine if an interlocking bolt would limit subsidence of the biological fixation universal hip (BFX(®)) femoral stem under cyclic loading and enhance construct stiffness, yield, and failure properties. STUDY DESIGN Ex vivo biomechanical study. ANIMALS Cadaveric canine femora (10 pairs). METHODS Paired femora implanted with a traditional stem or an interlocking stem (constr...

This study sought to determine the utility of an interlocking finger task in screening for parietal lobe dysfunction. The ability of 69 patients to imitate a standardised set of four interlocking finger figures was compared with concurrent performance on formal neurocognitive tests. Poor interlocking finger test scores correlated most highly with standard measures of parietal lobe dysfunction. ...

Objective: To compare the outcome (union) between reamed and unreamed nailing in tibial diaphyseal fracture (transverse). Material and methods: This randomized study was carried out in the Department of Orthopedic Surgery, Nishtar Hospital, Multan from January 2009 to September 2009. Two hundred and ten patients were divided into two groups A and B. Group A patients were managed by reamed inter...

of diaphyseal long bone fractures. Interlocking nails have transverse cannulations that accommodate transcortical screws, allowing surgeons to firmly fix the rod within the medullary canal, thereby effectively neutralizing bending, rotational, and axial forces that act on fractures. Interlocking nails have become increasingly To counter axial and rotational forces, intramedullary nails were dev...

According to the masonry standard the compressive strength is basically dependent on factors such as the mortar strength and the relative values of unit and mortar strength. However interlocking brick has none or less use of mortar. Therefore there is a need to investigate the behavior of masonry walls using interlocking bricks. In this study a series of tests have been conducted; physical prop...
