Background: The durability of physicians working in the family physician program is one of the most important factors in effective implementation of this program. This study aimed to investigate the individual, organizational, and environmental factors affecting the family physicians' durability in Rafsanjan University of Medical Sciences in 2019. Methods: This descriptive-analytical study was...
Finite Element Analysis (FEA) has been widely used to analyze the in vivo structural response of implantable medical devices and assess device performance, reliability and durability. Take stents for example. Several characteristics like radial force, peak stresses and strains and fatigue safety factors can be determined using these modeling techniques. As all physical phenomena are stochastic,...
hedging is a multi-purpose rhetorical strategy which is usually used in scientific arguments to secure ratification of claims, reduce the risk of negation, avoid conflict, manage disagreement and leave room for the audience to assess presented information. hedges are frequently used in research articles to mitigate the findings of research endeavors. the present research aims to investigate the...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...
The reliability and durability of an ultrasonic motor is usually determined by wear at the contact interface between a drive and a driven element, due to its driving mechanism. Wear control is therefore essential as the key design input to achieve ultimate performance of the ultrasonic motor. In this paper, a high precision and small precise positioning linear stage with an ultrasonic motor as ...
Experience with heat recovery steam generators (HRSGs) designed for larger-heat-input and higher-steam conditions highlights limitations in some features of traditional designs extrapolated from smaller HRSGs that operated predominantly continuously. Many combined-cycle units may be subjected to periods of regular overnight shut-down much earlier than expected and, unless anticipated during the...
Technology Readiness Levels (TRLs) are a means to categorize the relative technical maturity of components, sub-systems, or systems. Technological or technical maturity is a measure of performance, reliability, durability, and operating experience, and more technologically mature components (better performing, more reliable, more durable, greater operating experience) are rated higher than expe...
