The B-Factory is a high-energy physics project at SLAC that studies the phenomenon of CP violation from collisions between two stored beams; high energy electrons (HER, maximum 12-GeV) and low energy positrons (LER, maximum 4-GeV). Both the HER and LER are located in an underground tunnel of 2200-m-long circumference with a maximum stored current of 3 A. '-The injector consists of the existing ...

In the German Aerospace Center, DLR, an internal project has been launched to investigate different UCAV configurations. One aspect, covered by the Institute of Aeroelasticity and the Institute of Aerodynamics and Flow Technology, is the wind tunnel test of a UCAV wing in subsonic and transonic flow. The model shall show measurable static aeroelastic deformations. Main goals of the tests will b...

Semakin maju teknologi digital dapat menyebabkan memudarnya nilai-nilai karakter, sehingga perlunya fondasi pendidikan karakter pada generasi alpha khususnya anak usia dini, artikel ini bertujuan untuk mengidentifikasi pentingnya penerapan dini terhadap di abad 21. Metode yang digunakan yaitu studi pustaka atau literature. Hasil penelitian 21 harus memiliki 4C berpikir kritis dan menyelesaikan ...

SWISSMETRO is a MAGLEV Project, designed for a speed up to 500 km/h in two tunnels under partial vacuum. The authors investigate new possibilities to combine the propulsion and levitation. Polarized inductors for the levitation are studied, implying a polarized (permanent magnet) synchronous linear motor. The thermal behavior is investigated using a numerical platform of the complete vehicle-tu...

Carpal tunnel syndrome, trigger fingers, and deQuervaines’ tenosynovitis are often regarded as surgical lesions. Using an interprofessional team approach, all these conditions can be treated with nonsurgical techniques. A 44-year-old accountant presented with hand pain requiring workplace accommodation. He had electrodiagnositc evidence of carpal tunnel syndrome bilaterally with the right side ...

Rockburst disasters frequently occur in deep tunnels excavated by TBM (tunnel boring machine) under complex geological conditions western China. Using FLAC3D, the characterization of a three-dimensional numerical model compound stratum tunnel is conducted, based on water transport project Shanxi Province. Then, characteristics rockburst hard and soft are revealed, energy criteria considering ro...

Nowadays deep excavations are needed for construction of foundation of high rise buildings, providing space for parking and etc. In some cases deep excavations may be constructed in the vicinity of the subway tunnels and causes unpredicted extra displacements and internal forces in tunnel lining of tunnels which were not designed for them and consequently affect serviceability of tunnel. Theref...
