    Notes: Application of the matrix intensity equation of X-ray diffraction is discussed for the second problem of extrinsic faults in face-centred cubic crystals, discussed by Howard [Acta Cryst. (1977), A33, 29-32]. The second problem is generalized to the case that the probability with which inserted layers follow layers of the original crystal differs from that with which inserted layers follow previously inserted layers. The Q matrix for the case is obtained and the results of intensity calculation are shown.

    Notes: Clinical and immunological studies were made in forty-two patients diagnosed as suffering from hypersensitivity pneumonitis at Osaka Prefectural Habikino Hospital between 1973 and 1977. All the sera from forty-one patients tested had high litres of antibody against Cryptococcus neoformans in indirect fluorescent antibody tests, and twelve also had precipitins against Cryptococcus neoformans polysaccharide. Only about 10% of control sera from patients with otherlung diseases had low titresof antibody against Cryptococcus neoformans. Antibody against Cryptococcus neoformans was also found frequently in the sera of asymptomatic members of the families of the patients. A possible relationship of Cryptococcus neoformans to hypersensitivity pneumonitis is suggested.

    Serologic evidence for etiologic role of Akabane virus in epizootic abortion-arthrogryposis-hydranencephaly in cattle in Japan, 1972–1974 (1975)

    Notes: Summary In the outbreak of abortions, premature births, stillbirths and congenital arthrogryposis-hydranencephaly (AH) syndrome in Japan during the summer through winter of 1972–73 and 1973–74, precolostral sera from calves with congenital AH syndrome and normal calves were tested for neutralizing antibodies against some arboviruses,i. e. Akabane, Aino, Getah and Japanese encephalitis (JE) viruses. The incidence of antibody for Akabane virus was very high in calves with AH syndrome (49/59 or 83 per cent) as compared with normal calves (3/11 or 27 per cent), indicating an intimate correlation between the AH syndrome and precolostral anti-Akabane antibody. Three stillborn fetuses also had anti-Akabane antibody. On the other hand, no precolostral serum antibody for the other viruses was detected in any of the calves tested. The mothers of these calves, normal and with AH syndrome, had anti-Akabane antibody in high percentages (44/52 or 85 per cent and 7/8 or 88 per cent), whereas a few of the mothers had antibodies for the other viruses. Serological surveys indicate a wide dissemination of Akabane virus in epizootic areas during the summer months of 1972 and 1973. Thus, 8 groups of cattle in epizootic areas showed high rates of seroconversion for Akabane virus during the 1972 or 1973 summer. Very high incidences of Akabane antibody were shown among cattle in epizootic areas but extremely low incidences in near-by non-epizootic areas. The geographic distribution of anti-Akabane antibody among cattle throughout the country in the 1973 spring generally agrees with the pattern of case distribution in the 1972–73 outbreak. All these findings strongly suggest that Akabane virus is the etiological agent of the outbreaks. Further studies are needed, particularly isolation of the virus, demonstration of infection with the virus in lesions by immunofluorescence and production of intrauterine infection by experimental infection of pregnant cows.

    Analysis of neutron yield produced by high-energy proton (1979)

    Notes: Abstract Comparisons have been made between computational results obtained with the BNL code system and experimental data measured by Vasfl'kov et al. for 56 x 56 x 64 cm natural and depleted uranium blocks surrounded by lead walls and primary proton energies of 400 and 660 MeV. The energetic protons from a linear accelerator are used to produce an intensive neutron source inthe uraniumblocko The computercode system prepared at BNL to perform nuclear design analyses of linear accelerator reactors consists of six main programs: NMTC for spallation-evaporation processes above 15 MeV, HIST3D for the analysis of collision event records obtained by NMTC to get P3 neutron source distribution, DLC-2 to compile 100 energy group cross sections, TAPEMAKER for format conversion, ANISN to collapse 100 group cross sections to fewer group P3 cross section sets, and the principal code TWOTRAN-II which performs neutron reaction and transport calculations in the energy range below 15 MeV. Our computational method gives conservative total neutron yields, i.e., underestimates of about 16.8–29.8% in comparison with measured values depending on proton energy. Radiative capture238U(n,ψ) density distributions have been compared between the calculation and experiment. The calculated distribution has the higher peak in the central part of the target system and the steeper gradient both in the r and z directions.

    Description / Table of Contents: Zusammenfassung Es wurden Oberflächenveränderungen von Aktivkohlen durch nasse Oxidation und die daraus resultierenden Adsorptionseigenschaften untersucht. Die Oxidation der Aktivkohle mit Wasserstoffperoxid oder Salpetersäure verminderte die spezifische Oberfläche von 1101 m2/g auf 574 m2/g, erhöhte die Benetzungswärme in Wasser von 9,1 cal/g auf 22,9 cal/g und verminderte die Benetzungswärme in Ethanol von 28,4 cal/g auf 18,8 cal/g. Die mittlere elektrostatische Feldstärke stieg gleichzeitig von 0 auf 1,90. 104 e.s.u./cm2. Die Porenstruktur mit einem Durchmesser von etwa 14 Å wurde zerstört. Durch die Oxidation wurde das Adsorptionsvermögen von Wasserdampf, Alizaringelb und Anilin in Åthanollösung verbessert, die Adsorption von Phenol, Anilin und Alizaringelb in wäßriger Lösung dagegen herabgesetzt.
    Notes: Summary The surface changes of active carbon by wet oxidation and the resulting changes in adsorptivity were studied. The oxidation of active carbon with hydrogen peroxide or nitric acid solutions caused the changes of the specific surface area from 1101 m2/g to 574 m2/g, immersional heat into water from 9.1 cal/g to 22.9 cal/g and immersional heat into ethanol from 28.4 cal/g to 18.8 cal/g. The average electrostatic field strength increased from 0 to 1.90 x 104 e. s. u./cm2 as well. Pore structure with the diameter around 14 A was partly damaged. The adsorption of water vapor and alizarin yellow and aniline dissolved in ethanol by the carbon was promoted by these oxidations whereas the adsorption of phenol, aniline and alizarin yellow from aqueous solutions were depressed.

    Notes: Membranes were dynamically formed from poly(acrylic acid), poly(1-methyl-2-vinylpyridinium iodide), and methylcellulose on a Millipore filter. The effects of the conditions of membrane formation on reverse osmosis performances and the membrane structure were investigated. The primary factors that affect membrane performance were ascertained to be the kind and concentration of salts and the pH of the preparing solutions, the concentration and the polymerization degree of the membrane materials, the pore size of filters, and the pressure and circulation velocity during membrane formation. Two types of dynamically formed membranes, the membranes inside the filter and the membranes on the filter, were distinguished.

    Permselectivities of some aromatic compounds in organic medium through cellulose acetate membranes by reverse osmosis (1978)

    Notes: Reverse osmosis of some aromatic compounds in 1-propanol solution using porous cellulose acetate membranes and some factors which influence the organic solute permeability were investigated. Reverse osmosis data for a number of benzene derivatives showed that only phenol was rejected and the others were enriched. For the compounds with various substituent groups, the solute permeabilities have the following order; OH 〈 CH3 〈 H 〈 Cl 〈 NH2 〈 NO2. In the series of benzene, naphthalene, and anthracene, the permeability is related to the molar volume of solutes and varied as follows: benzene 〈 naphthalene 〈 anthracene. Generally speaking, there are two factors - a partition coefficient and a diffusion coefficient - for governing the permeation behavior through the membrane. Under the condition that no steric effect is exerted, the partition coefficient exclusively is a dominant factor. A good correlation between the partition coefficient of a particle and that of the membrane was pound. The partition coefficients are closely related to the dipole moment of solutes.
