Due to some beam dynamic requirement, accelerating cavities for TESLA injector linacs should be embedded into solenoid magnetic field and TESLA superconducting cavities can not be applied. Consideration shows the Cut Disk Structure (CDS) as a good option for TESLA Normal Conducting (NC) accelerating cavities. The structure cells shape has been optimised at operating frequency 1300 MHz for diffe...

The effect of adrenalectomy on neutrophil and monocyte migration into rat peritoneal and pleural cavities was investigated. Carrageenin- or thioglycollate-induced neutrophil emigration into both cavities was enhanced by adrenalectomy. In contrast, monocyte migration into peritoneal cavities induced by these two stimuli was significantl decreased. In pleural cavities, adrenalectomy enhanced the ...

PURPOSE To analyze 2 factors that influence timing of radiosurgery after surgical resection of brain metastases: target volume dynamics and intracranial tumor progression in the interval between surgery and cavity stereotactic radiosurgery (SRS). METHODS AND MATERIALS Three diagnostic magnetic resonance imaging (MRI) scans were retrospectively analyzed for 41 patients with a total of 43 resec...

The Booster synchrotron at Fermilab employs eighteen 37–53 MHz ferrite-tuned double-gap coaxial radiofrequency cavities for acceleration of protons from 400 MeV to 8 GeV. The cavities have an aperture of 2.25 inches and operate at 55 kV per cavity. Future high duty factor operation of the Booster will be problematic due to unavoidable beam loss at the cavities resulting in excessive activation....

The HL-LHC upgrade will use deflecting (or crab) cavities to compensate for geometric luminosity loss at low *  and non-zero crossing angle. A local scheme with crab cavity pairs across the IPs is used employing compact crab cavities at 400 MHz. Design of the cavities, the cryomodules and the RF system is well advanced. The LHC crab cavities will be validated initially with proton beam in the ...

The geometry of cavities in the surfaces of proteins facilitates a variety of biochemical functions. To better understand the biochemical nature of protein cavities, the shape, size, chemical properties, and evolutionary nature of functional and nonfunctional surface cavities have been exhaustively surveyed in protein structures. The rigidity of surface cavities, however, is not immediately ava...

The configuration factor of adhesive cavities is defined as the ratio of the restoration's bonded to unbonded (free) surfaces. Such a configuration factor was described, on ideal cavities, as having a potential value in predicting the behaviour of the restorations, because it is related to the restoration's capacity for relieving stress by flow. The aim of this study was to measure the configur...

Introduction: Supernumerary teeth are frequently reported in dental clinical practice; however, eruption in nasal cavities and paranasal sinuses is an extremely rare clinical entity.   Case Report: We report two cases with a history of recurrent nasal discharge and obstruction. In both cases, clinical and radiological findings confirmed the presence of an inverted supern...

Ahstracr: I tested the effectiveness of squirrel excluder devices (SQEDs) in deterring southern flying squirrels (G h ucom y s rduns ) from using artificial red-cockaded woodpecker (Picoidcs horeulis) cavities by placing them on approximately one-half of the cavities in I4 inactive recruitment clusters on the Savannah River Site, South Carolina. SQEDs consisted of 2 pieces of 35.5-cm wide alumi...
