Dental ceramics represents a major structural material in fixed prosthodontics. Increasing demands for esthetics led to development of new ceramic materials in order to eliminate the use of metal framework and for all ceramic restorations with mechanical properties to withstand high occlusal forces. Out of all the present ceramic materials, zirconium-ceramic has the best mechanical properties, ...

Tensile strength is a crucial parameter involved in the design and analysis of cemented paste backfill (CPB). The ability CPB to withstand tensile forces essential for stability backfilled stopes, particularly areas with high stress or deformation. critical used sill mats perform underhand cut-and-fill operations. This study presents novel technique that utilizes rectangular dog-bone specimens ...

As issues related to sustainable construction in Malaysia gains more importance, research on the utilization of waste by products especially from oil palm concrete is vigorously implemented. Utilization different parts fibres lightweight foamed have garnered positive outcomes terms conservation natural resources, lessening environmental problem and can improve concrete's durability mechanical p...

Some assessment and diagnosis methods require palpation or the application of certain forces on the skin, which affects the structures beneath, we highlight the importance of defining possible influences on skin temperature as a result of this physical contact. Thus, the aim of the present study is to determine the ideal time for performing thermographic examination after palpation based on the...

Knowledge of the mechanical properties of double-stranded DNA (dsDNA) is essential to understand the role of dsDNA looping in gene regulation and the mechanochemistry of molecular machines that operate on dsDNA. Here, we use a newly developed tool, force sensors with optical readout, to measure the forces inside short, strained loops composed of both dsDNA and single-stranded DNA. By varying th...

Understanding security failures of cryptographic protocols is the key to both patching existing protocols and designing future schemes. Recently, Yeh et al. showed that Hsiang and Shih’s password-based remote user authentication scheme is vulnerable to various attacks if the smart card is nontamper resistant, and proposed an improved version which was claimed to be efficient and secure. In this...

INTRODUCTION: Articular cartilage, the load bearing material of synovial joints, can normally withstand loads reaching several times body weight. The presence of proteoglycans in cartilage causes it to swell and enhances its ability to bear compressive load. Previo us studies have measured the osmotic pressure of chondroitin sulfate (CS), the most abundant glycosaminoglycan (GAG) found in carti...
