Background: Every year, eating, exercise, work, and travel patterns change during the holidays and these behavioral changes at a larger scale may cause death due to cardiovascular disease (CVD). Considering the importance of CVD, the present study was conducted for the first time in Iran to determine the differences in the ratio of deaths due to CVD on holidays and working days. Materials an...

OBJECTIVE We examined diabetes as a cardiovascular disease (CVD) risk equivalent based on severity and other CVD factors. RESEARCH DESIGN AND METHODS pooled four U.S. cohorts (Atherosclerosis Risk in Communities [ARIC], Jackson Heart Study [JHS], Multi-Ethnic of Atherosclerosis [MESA], Framingham Offspring Cohort [FHS-Offspring]) classified subjects into groups by baseline diabetes/CVD status (...

we evaluated the effect of fe/alumina catalyst contained different cadmium contents and two synthesis temperatures on producing carbon nanotubes by chemical vapor deposition of methane as a feedstock.  x-ray powder diffraction (xrd), n2 adsorption-desorption, scanning electron microscopy (sem), transmission electron microscopy (tem), raman spectroscopy and thermogravimetry analysis (tga) were u...

this review paper provides researcherwith a comprehensive information about the carbon nano tubes and the catalyst parameters that influences theproduction and morphology of the of carbon nano tubes.carbon nanotubes, referred to as cnts, are one of the most important materials used in electrical, mechanical, thermal, chemical and textile industries. since discovery of cnts in 1991, many scienti...

germanium nanowires (genws) were synthesized using chemical vapor deposition (cvd) based on vapor–liquid–solid (vls) mechanism with au nanoparticles as catalyst and germanium tetrachloride (gecl4) as a precursor of germanium. au catalysts were deposited on silicon wafer as a thin film, firstly by sputtering technique and secondly by submerging the silicon substrates in au colloidal solution, wh...

this paper discusses the use of box behnken design (bbd) approach to plan the experiments for turning the yield of cvd, thickness and layer number of graphene sheets with an overall objective of optimizing the process to provide higher graphene production volume, fewer layers and thinness structure of graphene. bbd is having the maximum efficiency for an experiment involving four factors such a...

conclusions herein we have described the stata package “adpredsurv” for calculation of the nam-d’agostino x2 goodness of fit test as well as cut point-free and cut point-based nri, relative and absolute idi, and survival-based regression analyses. we hope this work encourages the use of novel methods in examining predictive capacity of the emerging plethora of novel biomarkers. background a fun...
