chemical vapor deposition (cvd) is one of the most popular methods for producing carbon nanotubes (cnts). the growth rate of cnts based on cvd technique is investigated by using a numerical model based on finite volume method. inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal cvd reactor at atmospheric pressure. in thi...

BACKGROUND Family history of cardiovascular disease (CVD) is an independent risk factor for CVD. Therefore, efforts to prevent CVD among asymptomatic persons with a family history are warranted. Little is known about preventive recommendations clinicians offer their patients with a family history of CVD, and adherence to preventive recommendations by patients at risk for CVD has not been well d...

AIM To evaluate the additional prognostic value of family history for the estimation of cardiovascular (CVD) mortality risk in middle-aged urban Lithuanian men. METHODS The association between family history of CVD and the risk of CVD mortality was examined in a population-based cohort of 6,098 men enrolled during 1972-1974 and 1976-1980 in Kaunas, Lithuania. After up to 40 years of follow-up...

CONTEXT While parental cardiovascular disease (CVD) doubles the risk for CVD in offspring, the extent of increased risk associated with sibling CVD is unclear. OBJECTIVE To determine, using validated events, whether sibling CVD predicts outcome in middle-aged adults independent of other risk factors. DESIGN, SETTING, AND PARTICIPANTS The Framingham Offspring Study, an inception cohort of th...

For the emerging semiconductor material silicon carbide (SiC) used in high power devices, chemical vapor deposition (CVD) is the most prominent method to create the electrically active SiC epitaxial layers in the device. The process of growing such epitaxial layers is to use a hydrocarbon and silane diluted in hydrogen flow through a hot chamber where chemical reactions take place in such a man...

Nowadays, it is known that oxidative stress plays at least two roles within the cell, the generation of cellular damage and the involvement in several signaling pathways in its balanced normal state. So far, a substantial amount of time and effort has been expended in the search for a clear link between cardiovascular disease (CVD) and the effects of oxidative stress. Here, we present an overvi...

BACKGROUND There is limited evidence on whether having pre-existing cardiovascular disease (CVD) or risk factors for CVD such as diabetes, ensures greater knowledge of risk factors important for motivating preventative behaviours. Our objective was to compare knowledge among the Australian public participating in a health check program and their risk status. METHODS Data from the Stroke Found...

non-communicable disease (ncd) accounts for a large and increasing burden of disease worldwide. it is currently estimated that ncds accounts for approximately 59% of global deaths and 43% of the global disease burden; this is projected to increase to 73% of deaths and 60% of disease burden by 2020. 1 in comparison, ncds in low- and middle-income populations accounts for 78% of the global ncd bu...
