Introduction: Ultra-high molecular weight polyethylene oxidation remains an important concern in total joint arthroplasty, since it eventually results in a significant drop in mechanical properties that may compromise implant longevity, especially for TKA [1-3]. In vivo oxidation of polyethylene can occur in the presence of unstabilized macroradicals within the polymer and molecular oxygen upta...

Ionization sources other than HII regions give rise to the right-hand branch in standard ([NII]) BPT diagram, populated by Seyfert 2s and LINERs. However, because majority of Seyfert/LINER hosts are star forming (SF), contaminate observed lines some extent, making it unclear if position along is merely due various degrees mixing between pure SF, or whether reflects intrinsic diversity ionizing ...

Typical motifs of a rāga can be found in the various songs that are composed in the same rāga by different composers. The compositions in Carnatic music have a definite structure, the one commonly seen being pallavi, anupallavi and charanam. The tala is also fixed for every song. Taking lines corresponding to one or more cycles of the pallavi, anupallavi and charanam as one-liners, one-liners a...

Release liners are part of a composite made of a label with its own adhesive on a release liner or carrier with its own release coating. The label comprises either a synthetic face stock such as polypropylene or paper. The adhesive is usually an organic material such as a polyacrylate or polyisoprene based rubber. The release liner can be made from various substrates treated with a suitable pro...

This paper presents a unified algorithm for studying the eigenvalue problem of a lined duct using the homotopy method. Results from various validations show that the method developed in this work can provide accurate and reliable numerical solutions for sound-propagation computation. The investigation also indicates that homotopy methods not only overcome the computational difficulties of the e...

The readiness and mental challenges of health care front-liners are one the big issues that need to be addressed by Ministry Health Malaysia (MOH) also Malaysian Board Counselors (MBC). This is ensure all threats can overcome in order streamline duties fighting COVID-19 pandemic Malaysia. Therefore, this study aims understand front workers (Font liners) facing pandemic. uses a qualitative desig...

Bragdon, C.R; Wannomae, K. K.; Lozynsky, A.; Micheli, B.; Malchau, H. Harris Orthopaedic Biomechanics and Biomaterials Laboratory, Massachusetts General Hospital, Boston, MA 02114 Senior author [email protected] INTRODUCTION: Oxidized zirconium (OxiniumTM) is a bearing surface introduced for use in THA to minimize wear in vivo. Oxinium femoral heads are manufactured by oxidizing wrought Zr-...

STATEMENT OF PROBLEM Two potential problems commonly identified with a denture base incorporating a resilient liner are failure of the bond between acrylic resin and soft liner material, and loss of resiliency of the soft liner over time. Since patients may drink different beverages, it is important to evaluate their effects on physical properties of soft lining materials. PURPOSE The objecti...

Using high-strength steels for pressure shafts and tunnel liners and taking into account significant rock mass participation allows the design of comparatively thin steel liners in hydropower projects. Nevertheless, during emptying of waterways, these steel linings may be endangered by buckling. Compared with traditional measures such as increased steel liner thickness and stiffeners, pressure ...

Abstract—Woolcool is an eco–friendly type of packaging, made of 100% pure sheep’s wool, hygienically sealed in recyclable food– grade wrap. Due to its complex physical and chemical composition, wool can also help control humidity and reduce condensation. Given these properties, the potential of wool to be used as packaging liners for the transport of meat is of interest. The present study asses...
