Published 1996Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Highly split, visible light emissions at room temperature were observed in the range from 335 to 650 nm in silicon-rich oxide films deposited in the plasma phase of a mixture of silane and oxygen. The mechanism of the light emissions is classified into two categories. The photoluminescence bands at both 365 and 469 nm are related to the intrinsic defects of the E′ center and the neutral oxygen vacancy, respectively. However, the relatively sharp peaks at 403 and 535 nm are correlated with the development of polycrystalline core of Si-enriched parts. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Highly efficient extraction of photoluminescence is observed from two-dimensional photonic crystal slabs employing InGaAs quantum dots as active material. The introduction of quantum dots reduces diffusion of carriers and thereby suppresses the surface recombination at the air-hole sidewalls of the photonic crystal. Around the normalized frequency of 0.7, over thirty-fold enhancement of the photoluminescence extraction is achieved at 78 K, indicating strong coupling to leaky modes of the free-standing photonic crystal slab. In addition, when the photoluminescence spectra overlaps with a photonic band gap, enhanced light extraction originating from the photonic band gap is observed experimentally. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2005Staff ViewISSN: 1365-2516Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Summary. Haemophilia A is an X-linked inherited bleeding disorder. Linkage diagnosis using polymorphic markers in the factor VIII gene is used to archive the carrier detection and prenatal diagnosis. The objective of this study was to establish the allele frequency and heterozygosity rate (HR) of two new intragenic markers (Intron 1 and 24) and other markers (Intron 13 and 22) using fluorescent PCR. Five hundred unrelated healthy women were screened and haemophilic family was studied for carrier detection and prenatal diagnosis. We observed five different alleles of Intron 1, 10 of Intron 24, nine of Intron 13 and six of Intron 22. The observed HR for Intron 1, 24, 13 and 22 were 34.0, 35.2, 53.0 and 42.6%, while the expected HR were 33.6, 36.3, 50.1 and 44.3%, respectively. Heterozygosity rate with the combined use of all four intragenic markers was 76.6% (383/500). In prenatal diagnosis of a haemophilic family, a pregnant woman was heterozygous with three intragenic (Intron 1, 13 and 22) and one extragenic St14 VNTR (DXS52) markers. She was considered to be a carrier, and she carried a male foetus by AMXY PCR and chromosome analysis of amniocytes. Foetus did not have mutant haplotype as his uncle, suggesting a normal male status. Our study demonstrates the utility of two new intragenic markers in FVIII gene for carrier detection and prenatal diagnosis of haemophilic families.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0797Source: Springer Online Journal Archives 1860-2000Topics: Process Engineering, Biotechnology, Nutrition TechnologyNotes: Abstract The gas phase holdup and mass transfer characteristics of carboxymethyl cellulose (CMC) solutions in a bubble column having a radial gas sparger have been determined and a new flow regime map has been proposed. The gas holdup increases with gas velocity in the bubbly flow regime, decreases in the churn-turbulent flow regime, and increases again in the slug flow regime. The volumetric mass transfer coefficient (k La) significantly decreases with increasing liquid viscosity. The gas holdup and k La values in the present bubble column of CMC solutions are found to be much higher than those in bubble columns or external-loop airlift columns with a plate-type sparger. The obtained gas phase holdup (ɛ g) and k La data have been correlated with pertinent dimensionless groups in both the bubbly and the churn-turbulent flow regimes.Type of Medium: Electronic ResourceURL: -

ISSN: 0942-0940Keywords: Keywords: Hemifacial spasm; atypical hemifacial spasm.Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary Among 155 cases of hemifacial spasm (HFS), the authors found two cases of atypical HFS (1.3%) in which spasm started with the orbicularis oris and buccinator muscles, and gradually spread upward to involve the orbicularis occuli muscle, whereas the reverse process is usually seen in cases of typical HFS. The compression site in cases of atypical HFS is the posterior/rostral aspect of the facial nerve (FN), whereas it was the anterior/caudal aspect of the FN in all cases of typical HFS except for one. The meatal loop of the anterior inferior cerebellar artery (AICA) compressed the FN when the vessel passed between the FN and the eighth cranial nerve (8th N). These findings suggest that the topographical organization in the FN in the cerebellopontine cistern may be reversed to a peripheral distribution: the fibres on the posterior/rostral side of the FN innervate the lower part of the facial muscles, and those in the anterior/caudal side of the nerve innervate the upper part of the facial muscles. When examining patients with HFS, we must very carefully determine whether patients have typical or atypical HFS, to determine whether blood vessels (usually the meatal loop of the AICA) between the FN and the 8th N as well as at the root exit zone of the FN are to be decompressed.Type of Medium: Electronic ResourceURL: -

ISSN: 0942-0940Keywords: Keywords: Neurovascular compression syndrome; the eighth cranial nerve; vertigo; tinnitus.Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary Forty-three surgical cases were retrospectively analyzed to establish diagnostic criteria and operative indications for vertigo and tinnitus due to neurovascular compression (NVC) of the eighth cranial nerve (8th N). Many NVC syndromes were mistakenly diagnosed as Ménière's disease or benign paroxysmal positional vertigo. NVC was confirmed in 31 of the 43 patients. Neurovascular decompression (NVD) resulted in complete recovery or marked improvement of subjective symptoms in all 19 cases with vertigo (100%), and in 19 of 29 patients with tinnitus (65.5%). Multiple factor analysis revealed that abnormal caloric responses have high diagnostic value for vertigo due to NVC. Vertigo due to NVC is of short duration (a few sec to a few min.) in the early phase of the disease, which becomes longer and hearing becomes impaired as the history of NVC lengthens. Low pitch pulsatile and high pitch continuous tinnitus are probably due to NVC and are cured by NVD if hearing is still preserved. Tinnitus associated with hemifacial spasm is strongly indicative of NVD. Decompression of the 8th N should be performed in the early phase of disease, since cochlear and vestibular functions are irreversibly impaired if NVC continues for a long period of time.Type of Medium: Electronic ResourceURL:
