Prospective switch study comparing two irrigation systems for transanal irrigation in children.

Background And Study Aims: Transanal irrigation (TAI) is used in children to treat constipation and incontinence. Belgium has 2 systems available: Colotip® (cheaper, however not designed for TAI) or Peristeen®.

Patients And Methods: This patient-control switch study is the first to compare 2 TAI systems.

Polarization-preserving confocal microscope for optical experiments in a dilution refrigerator with high magnetic field.

We present the design and operation of a fiber-based cryogenic confocal microscope. It is designed as a compact cold-finger that fits inside the bore of a superconducting magnet, and which is a modular unit that can be easily swapped between use in a dilution refrigerator and other cryostats. We aimed at application in quantum optical experiments with electron spins in semiconductors and the design has been optimized for driving with and detection of optical fields with well-defined polarizations.

Electrical detection of spin pumping due to the precessing magnetization of a single ferromagnet.

We report direct electrical detection of spin pumping, using a lateral normal-metal/ferromagnet/normal-metal device, where a single ferromagnet in ferromagnetic resonance pumps spin-polarized electrons into the normal metal, resulting in spin accumulation. The resulting backflow of spin current into the ferromagnet generates a dc voltage due to the spin-dependent conductivities of the ferromagnet. By comparing different contact materials (Al and/or Pt), we find, in agreement with theory, that the spin-related properties of the normal metal dictate the magnitude of the dc voltage.

[A comparative study of morbidity with temporary disability and hygienic assessment of working conditions of workers engaged in major occupations at the Dneproshina tire-manufacturing plant].

Comparative study (1979-81, 1965-67) of temporary disability showed its upward trend in tire vulcanizers by 20%. This fact was associated with unfavourable working conditions, workers' stability and aging, elevated physical work load. In the disease structure there occurred some changes: the share of osteomuscular diseases showed a rise and that of nervous and digestive diseases declined.
