    Notes: A triode-type field emission display has been fabricated using carbon nanotube emitters. Purified single walled carbon nanotubes were selectively deposited onto a cathode electrode in a triode-type structure by an electrophoresis. Emission current was modulated with gate potentials of 100–300 V. A high brightness of 1000 cd/m2 with uniform emission was obtained at 900 V at the anode and 200 V at the gate. The fluctuation of emission current was found to be less than 5% in a fully sealed field emission display. Selective deposition of carbon nanotubes by electrophoresis shows high feasibility for triode-type field emission displays. © 2001 American Institute of Physics.

    The effects of β2 adrenoceptor gene polymorphisms 
on pressor response during laryngoscopy and tracheal intubation (2002)

    Notes: We investigated whether human β2 adrenoceptor (β2AR) gene polymorphisms are associated with the pressor response to laryngoscopy and tracheal intubation. Ninety-two patients undergoing elective surgery under general anaesthesia were enrolled into this study. Arterial systolic pressure, heart rate and rate pressure product were measured before induction of anaesthesia and 1 min following laryngoscopy and tracheal intubation. Genomic DNA was then used to identify the β2AR-16 and β2AR-27 genes using an allele-specific polymerase chain reaction method. Using multiple linear regression models, controlling for age, sex, weight, baseline blood pressure, heart rate and rate pressure product, we found that patients who possessed the glutamic acid homozygote of β2AR-27 produced significantly greater changes in mean arterial pressure and rate pressure products than patients with the glutamine homozygote of β2AR-27 (β coefficient for mean blood pressure = 11.81, β coefficient for pulse−pressure product = 8.76, both p-values = 0.023). These findings suggest that genetic variability in the human β2AR gene polymorphisms may be associated with the pressor response to laryngoscopy and tracheal intubation.

    Pax-7 Immunoreactivity in the Post-natal Chicken Central Nervous System (2003)

    Notes: In this immunocytochemical study on the constitutive expression of Pax-7 protein in the postnatal chicken brain, Pax-7 showed region and cell type specific expression. In the optic tectum, only cells in grey matter showed positive immunoreactivities (IRs), whereas those in the white matters did not show any IRs. In thalamic nuclei and several pontine nuclei, we also localized Pax-7 positive IRs. On the contrary, in the cerebellum, Pax-7 was mainly localized within the Bergmann glia, whereas Purkinje cells did not show any IRs. In double immunolabelling studies, most of the Pax-7 IRs did not originate from neuroglial cells such as oligodendrocytes, microglia or astrocytes, but from neurons, with the exception of Bergmann glia in the cerebellum. The presence of Pax-7 IRs in the adult chicken brain could suggest that Pax-7 might play a role in maintaining normal physiological function in some postnatal chicken brain cells.

    Start-up and operation of anaerobic biofilters with packing alternatives (1989)

    Bioprocess and biosystems engineering 4 (1989), S. 275-281

    Notes: Abstract Four types of anaerobic upflow biofilters: non-packed (NP-AUBF), two-stage (2S-AUBF), multi-stage (MS-AUBF) and fully-packed (FP-AUBF), were tested for their start-up and operational performance characteristics. The volume of each filter was 12.1 dm3 (10 cm I.D.x155 cm in height). Stepwise seeding was conducted and the effect on the reduction of COD and gas production was monitored. When each reactor was loaded with 2 and 4 kg COD/m3-day of synthetic waste simulating alcohol production plant, 2S-, MS-, FP-AUBF had treatment efficiencies of 89–93%, while NP-AUBF showed efficiencies lower than 50%. As a conclusion, 2S- or MS-AUBF can be used as efficiently as FP-AUBF, while the amount of packings in the former is half that in FP-AUBF.
