The aim of this study was to present our experience of patients with penile strangulation. The clinical data of 6 patients (mean age, 36 years; range, 18-72 years) with penile strangulation caused by a metal hoop are provided, where the duration of strangulation was between 3 h and 1 month. Among these patients, the case of a 22-year-old patient with a steel hoop entrapment on his penis for 5 d...

The stress-bearing component of the bacterial cell wall--a multi-gigadalton bag-like molecule called the sacculus--is synthesized from peptidoglycan. Whereas the chemical composition and the 3-dimensional structure of the peptidoglycan subunit (in at least one conformation) are known, the architecture of the assembled sacculus is not. Four decades' worth of biochemical and electron microscopy e...

Fuel rod analysis program transient (FRAPTRAN) code was used to study the fuel rod performance during a postulated large break loss of coolant accident (LBLOCA) in Maanshan nuclear power plant (NPP). Previous transient results from thermal hydraulic code, TRACE, with the same LBLOCA scenario, were used as input boundary conditions for FRAPTRAN. The simulation results showed that the peak claddi...

The micromechanics of the formability a lean duplex TRIP steel was investigated using Synchrotron X-Ray Diffraction (S-XRD) measurements and Crystal Plasticity Finite Element Modeling (CPFEM). Specifically, effect ferrite phase on reduction stress concentrations in martensite influence austenite texture distribution deep-drawn were studied comparison to case. A series deep-drawing processes car...

Airway hyperresponsiveness (AHR) is a key characteristic of asthma that remains poorly understood. Tidal breathing and deep inspiration ordinarily cause rapid relaxation of airway smooth muscle (ASM) (as demonstrated via application of length fluctuations to tissue strips) and are therefore implicated in modulation of AHR, but in some cases (such as application of transmural pressure oscillatio...

The blast loading direction and in-situ stress field have an effect on the destruction process in surrounding rock around tunnel. Five blasting directions are considered experiment simulation. static distribution by confining pressure superposition waves discussed simulation LS-DYNA. Results indicated that hoop accelerates radial cracks growing, damage hole is not influenced direction. wave fai...

Abstract This paper summarizes an NIH-funded research project designed to study the strength of high temperature superconductors under circumferential hoop stress, in order qualify these materials for high-field (> 1 GHz-class) NMR magnets. The unique approach presented here is spin test coils at rotational speeds, approaching 50,000 rpm, induce mechanical stresses which are equivalent magne...

‘Curving’ could occur in Mode I brittle fracture and it can be attributed to the constraint. The variation of the apparent fracture toughness with constraint with or without crack curving is investigated. Using a critical opening or hoop stress as the fracture criterion, it is demonstrated that a fracture event can be quantified by two mechanics parameters, i.e. K and A3 for fracture without cu...

The use of composite materials in offshore engineering for deep sea oil production riser systems has drawn considerable interest due to the potential weight savings and improvement in durability. The design of composite risers consists of two stages: (1) local design based on critical local load cases, and (2) global analysis of the full length composite riser under global loads and assessment ...
