The brass tubes with foam cores of AlSi7SiC3, AlSi7SiC3Fe1 and AlSi7SiC3Fe3 were produced as the crush-boxes with circle and square cross-section. Then axial compressive behavior and energy absorption capability of the foam-filled tubes were investigated during the quasi-static progressive plastic buckling. The uniaxial compressive stress–strain curves of the foam-filled brass tubes exhibited t...

This study developed an ozone generator of a double co-axial cylindrical dielectric barrier discharge system with air, argon, and oxygen as the working gases. The was produced by using high voltage power supply 0 - 18 kV line frequency 50 Hz. flow rate varied from 1 to 6 L/min. A comparison O3 generation in brass central electrode conducted it found that concentration higher case than air argon...

INTRODUCTION There is a popular belief among some musicians that playing a wind instrument regularly can affect the position of the teeth. The aim of this study was to investigate this hypothesis. METHODS A cross-sectional observational study was carried out, comparing the occlusions of 170 professional musicians selected from 21 orchestras and organizations in the United Kingdom. The subject...

Idioms are a big part of languages but can cause trouble for communication, especially for non-native speakers of a language. Interpreting idioms correctly means that one must derive a figurative meaning from words that individually mean something else. Recent research primarily focuses on the impact of context for successful idiom comprehension and seems to prioritize native speakers’ understa...

The build-up dose in the megavoltage photon beams can be a limiting factor in intensity-modulated radiation therapy (IMRT) treatments. Excessive surface dose can cause patient discomfort and treatment interruptions, while underdosing may lead to tumor repopulation and local failure. Dose in the build-up region was investigated for IMRT delivery with solid brass compensator technique(compensator...

OBJECTIVE To determine the effect of exposure to metal dusts, fumes and high temperature levels among brass workers in comparison to a control group. STUDY DESIGN Analytical cross-sectional study. METHODOLOGY One hundred and fifty four brass workers were matched for age with 154 controls selected from the local population. An interviewer-administered questionnaire was used to determine the ...

Inductively coupled plasma-optical emission spectroscopy (ICP-OES) was used to determine the bulk metal elemental composition of 62 modern bronze sculptures cast in Paris in the first half of the twentieth century from the collections of The Art Institute of Chicago and the Philadelphia Museum of Art. As a result, a comprehensive survey of the alloy composition of the sculptures of many promine...
