    Notes: Abstract Core-level X-ray photoelectron-diffraction patterns have been measured from cleaved Bi2Sr2CaCu2O8+δ (001) surfaces for all elements present in this compound. The incommensurate modulation alongb ([010]) leads to a strong inequivalence ofa- andb-directions for Bi, Sr and Cu photoelectrons, while Ca and O emission show less effect. Ultraviolet-photoemission experiments recording the emission intensity at the Fermi energy over a large solid angle are also presented, providing a direct mapping of the Fermi surface. Ac(2×2) superstructure is observed on the Fermi surface suggesting antiferromagnetic correlations within the Cu−O planes. The effects of the lattice modulation are clearly observable at the Fermi energy, and they are enhanced for binding energies higher than a few tens of meV.

    Early aneurysm surgery and dehydration therapy in patients with severe subarachnoid haemorrhage without ICH (1996)

    Notes: Summary We prospectively analysed treatment results in patients with severe subarachnoid haemorrhage (SAH) who underwent early aneurysm surgery, and were managed by dehydration therapy. We studied a total of 31 patients with poor-grade SAH including 18 in grade IV, and 13 in grade V according to the WFNS classification system. Patients who were older than 70 years of age, or those with an intracerebral haemorrhage or absent brainstem response were excluded from this study. At surgery, clot evacuation from the peribrainstem cisterns with/without external decompression was performed following obliteration of the aneurysmal neck. In the early postoperative period, patients were maintained in negative water balance using osmotic diuretics. When delayed ischaemic deficits had manifested themselves, the pulmonary wedge pressure and/or central venous pressure was immediately increased by the rapid injection of albumin until hypovolaemia reverted to normovolaemia with the continuous administration of dobutamine. The outcome at 3 months was good recovery in 16 (52%) patients, moderate disability in 3 (10%), severe disability in 5 (16%), a vegetative state in 1 (3%), and death in 6 (19%). We thought that early aneurysm surgery and postoperative dehydration therapy in the acute stages of brain oedema resulting from primary brain damage are effective in the treatment of patients with severe SAH but reversilbe primary brain damage.

    Notes: The application of microbubbles of pressured CO2 greatly increased CO2 concentration in the solution treated. By treatment at 6 MPa, 35°C and average residence time 15 min, L. brevis was completely inactivated at the level of dissolved CO2,γ≧ 11 (γ, Kuenen's gas absorption coefficient). E. coli and S. cerevisiae required γ≧ 17, and T. versatilis required γ≧ 21 for complete inactivation. Z. rouxii could be sterilized at 20 MPa and 26. A comparison of the continuous and batch method showed that L. brevis was inactivated completely under pressured CO2 〉 0.16 g/cm3 with the continuous method and 〉0.9 g/cm3 with the batch method.

    Notes: Abstract . Core-level X-ray photoelectron-diffraction patterns have been measured from cleaved Bi2Sr2CaCu2- O8+δ (001) surfaces for all elements present in this compound. The incommensurate modulation along b ( [010] ) leads to a strong inequivalence of a- and b- directions for Bi, Sr and Cu photoelectrons, while Ca and O emission show less effect. Ultraviolet-photoemission experiments rec ording the emission intensity at the Fermi energy over a large solid angle are also presented, providing a direct mapping of the Fermi surface. A c(2×2) superstructure is observed on the Fermi surface suggest ing antiferromagnetic correlations within the Cu–O planes. The effects of the lattice modulation are clearly observable at the Fermi energy, and they are enhanced for binding energies higher than a few tens of meV.
