Abstract The present research exposes the investigation on three-dimensional modeling of single and twin metro tunnels for case Tehran line. At first, simulation implemented comparison ground movements in tunnels. Then has been performed influence effective parameters EPB-TBM surface settlements throughout excavation. overcutting, shield conicity, grouting, final lining system modeled face supp...

BACKGROUND According to the WHO report in 2015, obesity is the fifth leading cause of death worldwide, and the prevalence of Egyptian female obesity is 37.5 %. Since obesity is highly influenced by genetics, and adipose tissue renin-angiotensin system is over-activated in obesity, the effect of angiotensin-converting enzyme (ACE) insertion/deletion (I/D) polymorphism on obesity and related diso...

Generally, the equivalent conicity function (ECF) is denoted by at 3mm (?3mm) and a Nonlinearity Parameter (NP). NP describes nonlinearity of ECF its influence on vehicle design explored thoroughly, however, NP’s role in track maintenance not researched yet. This paper investigates actions dynamics with help vs ?3mm scatter plots database. The database constructed combining measured worn wheel ...

Titanium alloy is widely used in modern automobile industries due to its higher strength with corrosion resistance. Such materials can be effectively machined using unconventional machining processes, especially the electro-chemical micro (ECMM) process. It important enhance process by investigating effects of electrolytes and parameters ECMM. The presented work describes influence three differ...

Turnouts are the weak spot in high-speed rail systems, and it is simple for phenomenon of wheel–rail force carbody lateral acceleration over-limit to arise when train passes through, which affects service life running stability train. In this paper, turnout with selected analysis, profiles wheel monitored. Then, vehicle–turnout coupled multi-body dynamics model simulated. Additionally, portable...

Aim: This study was aimed to investigate visceral adiposity indicators and the atherogenic index of plasma (AIP) in type 2 diabetes mellitus (T2DM) patients. Material Methods: A total 353 adults aged between 18 74 years were included this study. Bodyweight, height, waist, hip circumference measured; fasting blood glucose, HbA1c, lipid profile (total cholesterol, triglyceride, low-density lipopr...

The association of systolic and diastolic blood pressure with body mass index, waist hip ratio, the sum of three trunk skinfolds, the sum of the six skinfolds, the ratio of the sum of the trunk to the sum of the extremity skinfolds and relative fat pattern index and the correlations between each of these were examined among 30 hypertensive and 30 normotensive post menopausal women of Udaipur ci...
