This study analyzes the design criteria for obtaining high slip-resistant shoe sole tread pattern the by adept control of various design parameters such as the height, orientation, and hardness of rubber strips. In the typical process, specimens of natural rubber (NR) strip with a width of 3 mm, length of 25 mm, and height of 1, 2, 3, 4, or 5 mm were affixed onto the base rubber sheet (25 mm × ...

This paper reports the use of rubber—Polybutadiene as an intermediate adhesive layer for improving the adhesion between polyimide (PI) and silicone polydimethylsiloxane (PDMS) which is required for a reliable fabrication of flexible/stretchable body patches for various applications. The adhesive bond initiated by the butyl rubber (BR), apart from being extremely strong, is also chemically resis...

New data on the epidemiology of peripheral artery disease (PAD) are available, and they should be integrated with previous data. We provide an updated, integrated overview of the epidemiology of PAD, a focused literature review was conducted on the epidemiology of PAD. The PAD results were grouped into symptoms, diagnosis, prevalence, and incidence both in the United States and globally, risk f...

Peripheral arterial disease (PAD) is a manifestation of atherosclerosis below the bifurcation of the abdominal aorta. PAD increases the risk of cardiovascular disease and associated mortality. Little is known about the prevalence of PAD in middle-aged persons with intellectual disabilities (ID). We determined the prevalence of PAD among people with ID aged 40-59 years. Independent associations ...

Because patients with peripheral arterial disease (PAD) may be asymptomatic or may present with atypical symptoms or findings, the true population prevalence of PAD is essentially unknown. We used four highly reliable, sophisticated noninvasive tests (segmental blood pressure, flow velocity by Doppler ultrasound, postocclusive reactive hyperemia, and pulse reappearance half-time) to assess the ...

Rubber-steel-layered structures are used in many engineering applications. Laminated rubber-steel bearing, as a type of seismic isolation device, is one of the most important applications of the rubber-steel-layered structures. Interfacial debonding in rubber-steel-layered structures is a typical failure mode, which can severely reduce their load-bearing capacity. In this paper, the authors dev...

INTRODUCTION  Resistin is an inflammatory mediator and a potential biomarker in cardiovascular diseases. OBJECTIVES  We sought to examine its association with peripheral arterial disease (PAD). PATIENTS AND METHODS  We recruited 200 patients with PAD and 100 healthy controls. Patients were divided into 4 subgroups according to the Fontaine classification for PAD, that is, from Stage I to St...

Mixtures of small rigid sand particles Ds and large soft rubber particles Dr are prepared at different volume fractions and tested to investigate their small-strain and zero-lateral strain responses (Dr /Ds & 10). Both data sets are simultaneously gathered in an oedometer cell instrumented with bender elements. Data are analyzed in the context of mixture theory and with the aid of numerical sim...

This study presents the development of natural rubber-Ca/P blends, as promising candidates for biomedical purposes. The specific objective was the incorporation of Ca/P into a natural rubber polymeric matrix. Ca/P crystalline phases were synthesized by the sol-gel method and the polymeric matrices were produced using natural rubber extracted from latex of the Hevea brasiliensis. The shape and s...

Soft tissue distraction (STD) is an increasingly accepted operation in all fields of hand surgery from elbow contracture release to PIP joint release. Current techniques reported lack the ability to distract the joints of the fingers or the hand, maintain the length of released contractures, and hold them in a position while active and passive physiotherapy is possible. We describe a technique ...
