    Notes:
    Photoluminescence and Raman spectroscopy are employed to explore the time evolution of defect formation in chemical vapor deposition diamond films for stages of growth spanning nucleation to continuous film formation. Our research is concentrated on three types of defects which give rise to the 1.68 eV optical band, the sp2 phase which centers at 1500 cm−1, and the broadband luminescence at 565–800 nm. The investigation of these types of defects suggests the following conclusions. Si atoms are most likely responsible for the creation of the 1.68 eV optical centers which takes place at the initial stages of growth. Plasma interactions with the Si substrate contribute to the 1.68 eV defect formation. The broad luminescence and sp2 bonding defects were not present in the isolated nuclei but were significantly present when a continuous film was formed. Two rates of diamond growth were obtained and the changes of the rates were attributed to the lowering degree of freedom available for the growth of the nuclei as well as to the formation of the sp2 phase.

    Notes:
    The surface topography of silicon substrates after the initial stages of diamond growth, by microwave plasma enhanced chemical vapor deposition, has been observed by scanning tunneling microscopy. The initial surfaces were polished with diamond paste before deposition to enhance nucleation, and the scratches were examined. After one half hour growth, the surface showed additional topography over all regions, and widely spaced faceted structures were detected which were attributed to diamond nuclei. The surface between nuclei showed increased roughness with increased deposition time. The faceted nuclei were found along the scratches. The nuclei showed facets which were smooth to within 5 A(ring). Fingerlike ridge structures were found extending from and in-between some of the nuclei. These structures indicate a mechanism of the lateral diamond growth. The electronic properties of the surface were probed by local I-V measurements, and characteristics attributable to SiC were observed.

    We present a combined experimental and theoretical investigation of intra- and intersubband carrier relaxation in GaAs/AlAs quantum wells following femtosecond laser excitation at low density. Time-resolved optical absorption has been measured using 125 fs pulses from a tunable Ti:sapphire laser which allows carriers to be excited preferentially into different subbands. The experiments have been analyzed using a multi-subband Monte Carlo simulation which contains all the important scattering mechanisms. Electron-phonon scattering rates obtained from dielectric continuum theory have been used, and we find excellent agreement with the experiment. The dominance of interface phonons in intrasubband relaxation is confirmed. © 1995 American Institute of Physics.

    Notes:
    We present a joint theoretical and experimental investigation of GaAs v-groove quantum wires confined in GaAs/AlAs superlattice barriers. We have computed the electronic states for both the quantum wire and the barriers. The intrinsic bending of the superlattice layers, together with systematic spatial variations of their thickness, create localized states in the barriers that are separated from the wire. This effect has a strong impact on the overall luminescence efficiency of the wires. The results are in excellent agreement with photoluminescence and photoluminescence excitation spectra. © 1995 American Institute of Physics.

    Notes:
    The presence of a high molecular weight glycoprotein component bearing the hapten phosphorylcholine (Pc) has been demonstrated in some but not all extracts of house dust mite using a phosphorylcholine specific IgA myeloma protein (S107). The Pc bearing component was isolated from house dust mite extracts by precipitation at equivalence using whole myeloma serum and the isolated fraction was found to be allergenic as judged by a direct RAST assay using a highly house dust mite allergic human serum pool. RAST inhibition studies using free hapten and direct RAST studies using pneumococcal polysaccharide C-substance indicated that the Pe moiety did not contribute significantly to the immunodominant portion of the isolated allergen. Further studies indicated that the S107 isolated material was immunochemically different from the tridacnin reactive material and the con A reactive material previously isolated from extracts of house dust mite.

    Notes:
    This study found a prevalence of asthma of 2.5% in adults and 0.2% in children in Goroka, the major town and administrative centre of the Eastern Highlands Province of Papua New Guinea. The disease features are similar to those found in previous studies in Papua New Guinea: late age of onset and virtual absence of childhood cases; strong association with allergy to house dust mite and high mite-specific IgE levels; and considerable impairment of resting lung function. However, the prevalence is much lower than that recently found in the nearby rural South Fore linguistic group of the Okapa District. Moreover, it was noted that a preponderance of the urban cases in the present study were originally from Okapa. The implication is that particular local tetiological factors may be responsible for the documented rise in prevalence in the South Fore (Okapa) people, rather than the process of ‘Westernization’per se. This creates a valuable opportunity to learn more about the pathogenesis of asthma.

    Notes:
    The recent dramatic rise from 0.1 to 7.3% in the prevalence of adult asthma in the South Fore area of the Eastern Highlands of Papua New Guinea (PNG) has not been matched by a similar increase in asthma in the adjacent Asaro valley, where the prevalence remains extremely low at 0.3%. While the living conditions of these two populations appear comparable, the mean density of house dust mite (principally Dermatophagoides pteronyssinus) in blankets of residents in the Asaro valley was found to be significantly lower (283/g dust) than that of a corresponding random selection in the South Fore (1371/g dust). Since from 200 to 600 mites per g dust have been reported to constitute a risk factor for asthma, the data suggest that the relative risk for asthma in the Asaro valley population is low compared with that in the South Fore. In randomly selected sera, both IgE and IgG antibodies to D. pteronyssinus from the Asaro valley were comparable with those of a group of non-asthmatics from the South Fore (mean 4.39 vs 3.43 U/ml for IgE antibodies and 1832 vs 1815 U/ml for IgG antibodies for Asaro valley vs South Fore, respectively) but significantly lower (P 〈 0.001) than corresponding data for subjects in the South Fore with asthma (108.6 U/ml and 3365 U/ml, respectively). This study emphasizes the interplay between genetic and environmental factors in determining the development of asthma, and highlights the importance of house dust mites in the pathogenesis of asthma in the Eastern Highlands of Papua New Guinea.

    Notes:
    The IgG, IgE and IgA antibody responses to the whole mite extract and a purified major mite allergen Der p 1, in sera from asthmatic and age- and sex-matched control subjects from the South Fore region of the Eastern Highlands of Papua New Guinea, have been studied. Radio-allergosorbent studies showed that the majority of the asthmatics, in contrast to control subjects, produced IgE to whole mite extract, and that Der p 1 was a major allergen in this population with 88% of mite allergic asthmatics responding. Enzyme-linked immunosorbent assay studies on these sera showed that the geometric mean levels of whole mite, but not Der p 1, specific IgG and IgA were significantly higher in the asthmatic group than in the control group. Significant correlations between whole mite specific IgG, IgE and IgA responses were obtained. These data indicate that Papua New Guinean asthmatics are similar to Caucasian asthmatic population with regard to serological responses to mite allergens, despite differences in disease presentation, particularly the late age of onset and severity of symptoms.

    Notes:
    Skin test results and IgE antibody levels measured by RAST indicate that hyper-sensitivity to house dust mite (D. pteronyssinus) is a major feature of asthma and allergic rhinitis in Indonesian children. Total serum IgE levels were higher in the allergic than in control children. 60% (twenty-one out of thirty-five) of the asthmatic children and 56% (five out of nine) of the children with allergic rhinitis had IgE antibodies to the helminth Ascaris lumbricoides compared with none out of four control children. A tendency was found for high IgE antibody levels to D. pteronyssinus to occur in association with low IgE antibody levels to A. lumbricoides and vice versa.

    Notes:
    Sputum samples from control subjects with cardiac disease and from patients with asthma were assayed for albumin content and immunoglobulins IgA, IgG, IgM and IgE. The asthmatics were divided into three groups: one group had received disodium cromoglycate (DSCG) for at least 48 hr prior to sampling, another group was sampled daily after commencing DSCG therapy and the third group were not taking DSCG. Albumin and immunoglobulins accounted for approximately 8% of the total sputum proteins in each of the four groups of subjects. There was no significant difference in the mean sputum levels of albumin or the immunoglobulins, when expressed as a percentage of total sputum proteins, between the subjects in each group. However, the ratios of IgA/albumin and IgA/IgG in the asthmatic group receiving DSCG were significantly lower than the corresponding ratios in sputa from both asthmatics and control subjects with cardiac disease. The sputum IgE levels tended to be higher in the asthmatics than in the control group, but DSCG therapy had little effect upon sputum IgE levels.

    Notes:
    The levels of total serum IgE and IgE antibodies to Aspergillus fumigatus allergens were highest during an episode of symptoms associated with fresh pulmonary shadowing and a rise in the direct cosinophil count in patients with allergic bronchopulmonary aspergillosis. Agglutinin titres were greater than those found in the sera of control subjects hut did not always correlate in magnitude with total serum IgE and IgE antibody levels. The highest agglutinin titre was found in the serum of a patient with an aspergilloma in association with allergic aspergillosis. The maximum in vitro histamine release from leucocytes exposed to A. fumigatus extracts or anti-human IgE was independent of the concentration of total IgE or IgL antibodies. The leucocytes appeared to he relatively insensitive to both allergic and reverse allergic histamine release. This was considered to result from either continuous in vivo desensitization of the leucocytes by antigens shed from the fungal hyphae or, to the effect of drugs used in the treatment of (he disease, It was concluded that serial serum IgE measurements may be of value in monitoring the onset of the active phase of this disease.

    Notes:
    Five allergen extracts of Dermatophagoides pteronyssinus, Lolium perenne, Alternaria tenuis, Aspergillus fumigatus and Cladosporium herbarum, obtained from four different manufacturers, were examined by inhibition of RAST, content of protein and carbohydrate, contents of phosphorylcholine (Pc) and tridacnin reactive components, and by skin test. Inhibition of RAST was used as a primary method for establishing allergenic potency and demonstrated wide variations for each preparation supplied by the different manufacturers. The extracts also varied widely in protein and carbohydrate content and in the ratio of these parameters, indicating internal heterogeneity. Pc content was significantly related to RAST potency for extracts of A. fumigatus and A. tenuis, suggesting that Pc content may be used as a primary standarization procedure for these extracts. Skin test reactions undertaken at a single concentration did not show any significant variation in weal size between preparations of a given allergen extract. However, of particular importance to practising clinicians is the finding that varying numbers of patients showed negative skin reactions to one preparation of a particular allergen yet were positive to the corresponding preparations supplied by the other companies.

    Notes:
    Fish behaviour varies considerably in response to changes in environmental and biological conditions. Cod (Gadus morhua) is not a homeothermic species and recent research has suggested that the recruitment and distribution of cod stocks may be influenced by temperature. Concerns have therefore been raised about the potential effect of climate change on stocks that are already at the southern limits of their range. We used data storage tags (DSTs) to observe the behaviour of cod in relation to temperature between 1999 and 2002. Over 3500 days of data were collected from 17 individuals tagged in the North and Irish Seas. We describe how the patterns in the temperature experience of cod are related to behavioural mechanisms, such as horizontal and vertical migration, that match habitat choice to physiological preferences. The results are discussed in the context of this behavioural response to short- and long-term shifts in thermal regime and the potential consequences on the overall behaviour and distribution of cod stocks.
