    Notes: The Pmel 17 gene is expressed preferentially in pigment cells. It has been mapped to human chromosome 12 pter-q21 and mouse chromosome 10, near the silver locus. The Pmel 17 gene contains an insertional mutation at its carboxyl terminus in the silver mouse, suggesting that the silver locus might correspond to the gene. In the current studies, we have isolated and characterized human Pmel 17 genomic clones and employed FISH mapping for a precise localization of this gene in the human chromosome. The FISH mapping placed the Pmel 17 gene at human chromosome 12 q12-q13. The human gene consists of nine exons and eight introns, and the entire coding region of the gene spans approximately 7.9 kb of the human chromosome 12. The putative functional domains, such as the signal sequence, histidine-rich, 26-amino acid repeats, cysteine-rich, transmembrane and cytoplasmic domains, were encoded by separate exons. Cis-transcription elements such as a TATA, a CAT and other potential elements for pigment cell-specific gene expression were found within 1100 base pairs of the 5’flanking region.

    Notes: Ribosome-inactivating protein from barley seeds has been crystallized using polyethylene glycol as precipitant. The crystal belongs to the monoclinic space group C2, with unit-cell parameters a = 88.36, b = 62.59, c = 53.18 Å and β = 108.62°. The asymmetric unit contains one molecule of ribosome-inactivating protein with a corresponding crystal volume per protein mass (Vm) of 2.32 Å3 Da−1 and a solvent content of 47% by volume. The crystal diffracts to about 2.3 Å with X-rays from a rotating-anode source and is very stable in the X-ray beam. X-ray data (nearly complete to 2.4 Å Bragg spacing) have been collected from a native crystal.

    Notes: Pseudomonas sp EL-2 was cultivated to produce poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)] from a structurally unrelated carbon source, glucose, by a fed-batch culture technique. Variation of the carbon to nitrogen (C/N) ratio of the medium produced optimal P(3HB-co-3HV) production at a C/N ratio of 95. Production of P(3HB-co-3HV) was favored by a dissolved oxygen tension of 40%. A maximum biomass concentration of 38 g L−1 containing 53% P(3HB-co-3HV) was achieved after 45 h of cultivation. This corresponds to a volumetric productivity of 0.84 g L−1 h−1. The copolymer contained 7.5 mol% 3-hydroxyvalerate. Journal of Industrial Microbiology & Biotechnology (2000) 24, 36–40.

    Notes: Abstract. A 26-year-old woman presented with epigastric pain, vomiting, and a palpable mass in the right lower abdomen. Ultrasonography showed a high echogenic mass associated with a small amount of ascites in the right lower abdomen. Computed tomography demonstrated entrapped ileal loops within a thin-walled fibrous capsule. A thin fibrous sac encasing the terminal ileum was detected on laparotomy and confirmed as idiopathic sclerosing encapsulating peritonitis. RID=""ID=""〈e5〉Correspondence to:〈/e5〉 M. Y. Kim

    Truss optimization considering homologous deformation under multiple loadings (1998)

    Notes: Abstract The deformation of a structure shall be called homologous, if a given geometrical relation holds for a given number of structural points before, during, and after the deformation. Some researchers have utilized the idea of structural design with the finite element method. The approaches use the decomposition of the FEM equation or equality equations to obtain homologous deformation. However, weight reduction and response constraints such as stress, displacement or natural frequency cannot be considered by those theories. An optimization method solving the above problems is suggested for obtaining homologous deformation. Homology constraints can be considered under multiple loading conditions as well as a single loading condition. A homology index is defined for multiple loading conditions. Examples are solved to demonstrate the performance of the method.

    Results of interferometer study of laval nozzle (1969)

    Notes: Abstract Interferometric measurement of the air density in a supersonic nozzle of rectangular cross section is described. The flow structure is studied in a real Laval nozzle. It is shown that the core flow follows the laws of motion of an ideal gas and has a wave nature. The relation δZ=(3−4)δy is obtained for the boundary layer thickness on the nozzle walls for nozzle width-height ratio L/h=3.75–7.5. The flow structure in a real supersonic nozzle may differ significantly from the theoretical structure, both because of defects in nozzle fabrication and because of boundary layer growth on the nozzle walls. In many casesitis important to know the param'eters of the supersonic flow in the actual nozzle. The determination of these parameters (density ρ, pressure ρ, temperature T, velocity u, Mach number M) at any section of the nozzle in question is the objective of the present investigation.

    Diffusion in nickel oxide pellets-effects of sintering and reduction (1974)
    Hoboken, NJ : Wiley-Blackwell

    Notes: Diffusion rates were measured at 25°C and 1 atm by a steady state method in pellets of nonporous nickel oxide particles in order to determine the effects of sintering and chemical reduction. Sintering led to a striking decrease in diffusion flux; tortuosities above 100 were found for highly sintered (porosity 0.03) pellets. Reduction caused a sharp increase in diffusion rate when the original pellet was highly sintered. For an originally unsintered pellet the diffusion rate decreased with extent of reduction.These phenomena were explained quantitatively by using: (1) the random pore model to predict tortuosity factors for an unsintered, unreduced pellet, and (2) the extent of pore interconnections and the fractional reduction to treat the effects of sintering and reduction. In this way an approximate, predictive equation was derived which contained no arbitrary parameters and which required for application only data on porosity and extent of chemical reduction.
