In order to further improve the static stiffness of hydrostatic bearing with membrane-type restrictor, in this study, a characteristics model pre-pressure single-action restrictor (PSMR) is derived, and criteria for achieving optimum are summarized. A PSMR design method following optimal proposed. Then, effect parameters on performance accurately evaluated by numerical simulation orthogonal exp...

conclusions the peripheral arterial disease is more frequent in patients with the severe form of cvi, than in patients without cvi. concomitant risk factors for cvi and pad were high bmi and hypertension. in each patient with severe cvi it is necessary to determine the abpi, in order to exclude the presence of pad. results our results showed that the risk factors for cvi were high body mass ind...

Tilting-pad journal bearings are widely used in industry to support rotating shafts due their high dynamic performance. The operating limits of these mainly represented by the maximum permissible temperature lined materials pads and minimum thickness oil-film under which mixed lubrication can occur. current trend bearing development sees adoption innovative production pads, that provide higher ...

BACKGROUND Lower-extremity peripheral arterial disease (PAD) is associated with decreased functional status, diminished quality of life, amputation, myocardial infarction, stroke, and death. Nevertheless, public knowledge of PAD as a morbid and mortal disease has not been previously assessed. METHODS AND RESULTS We performed a cross-sectional, population-based telephone survey of a nationally...

BACKGROUND We compared the incidence of depression, defined by a Geriatric Depression Score (GDS) ≥6, between people with versus without peripheral artery disease (PAD). We determined whether depressive symptoms were associated with increased mortality in people with and without PAD. METHODS AND RESULTS Nine hundred and fifty-one PAD patients and 478 non-PAD patients were recruited from Chica...

OBJECTIVE To analyze the contribution of genetic and environmental factors to the development of peripheral arterial disease (PAD) in a large population-based sample of twins. METHODS AND RESULTS The understanding of genetics in PAD is still limited. From the Swedish Twin Registry and the national patient discharge registry, 1464 twins with PAD were identified, including 33 monozygotic (MZ) a...

BACKGROUND Peripheral arterial disease (PAD) is a common manifestation of systemic atherosclerosis and is associated with significant morbidity and mortality. Diabetes is known to increase the risk of PAD two- to four-fold. The prevalence of PAD in Korean diabetic patients has not been established. In this study, we investigated the prevalence of PAD in Korean patients with type 2 diabetes atte...

Background To determine the prevalence of Peripheral Arterial Disease (PAD) and associated risk factors in patients undergoing amputation at the Korle Bu Teaching Hospital (KBTH), Accra, Ghana. Objectives A cross- sectional study of all patients undergoing lower extremity amputation at the Department of Surgery, KBTH. Materials A coded questionnaire was used to ascertain risk factors for PA...

BACKGROUND Outpatient ascertainment of peripheral artery disease (PAD) is rarely considered in the measurement of PAD clinical burden; therefore, the clinical burden of PAD likely has been underestimated while contributing to a decreased awareness of PAD in comparison to other circulatory system disorders. METHODS AND RESULTS The purpose of this study was to estimate the age-standardized annu...

Peripheral arterial disease (PAD) patients have augmented blood pressure increases during exercise, heightening their cardiovascular risk. However, it is unknown whether patients have exaggerated renal vasoconstriction during exercise and if oxidative stress contributes to this response. Eleven PAD patients and 10 controls (CON) performed 4-min mild, rhythmic, plantar flexion exercise of increa...
