A new genus Actinokineospora is described. It is characterized by forming chains of zoospores originating from aerial mycelium, and has type IV/A cell walls and a type PII phospholipids pattern. The major menaquinone is MK-10. No mycolic acids are present. The guanine-plus-cytosine content of the deoxyribonucleic acid…
The initial adsorption, structural transition, and polymeric growth of 1‐octyne‐3‐ol on iron electrode from sulfuric acid solutions have been examined by using time‐resolved in situ automatic ellipsometry. The adsorption occurs in two different configurations, flat and partly upright. The structural transition of the…
Mechanical properties of SiO2-Al2O3 ceramics were studied in relation to the chemical composition. Raw powders of the composition ranging from 60 to 78wt% Al2O3 were synthesized by the spray pyrolysis method and sintered at 1650°C for 4h. The room temperature flexural strength and fracture toughness of the specimens s…
Measurements of the reversible component of magnetization or reversible (backward) differential permeability made on 1% Mn pipeline steel at numerous points around major and minor hysteresis loops and on initial and anhysteretic curves are described. It is found that the reversible component of magnetization is a sing…
Abstract In the search for the causes of diatom assemblage distribution, a combination of two multivariate analyses has been used. Principal component analysis and canonical correlation analysis have allowed us to find suitable relationships between biological and physicochemical parameters. As a result, water salinit…
Abstract A technique for characterization of polymer blends by low voltage scanning electron microscopy is described. The method allows observation of the distribution of phases in a blend due to good topographical and compositional contrast. This is possible because of lower beam penetration and high secondary emissi…
A high-resolution temperature-concentration diagram and detailed differential scanning calorimetry data near an expected $\mathrm{s}\mathrm{m}\mathrm{e}\mathrm{c}\mathrm{t}\mathrm{i}\mathrm{c}\ensuremath{-}{A}_{1}\ensuremath{-}\mathrm{r}\mathrm{e}\mathrm{e}\mathrm{n}\mathrm{t}\mathrm{r}\mathrm{a}\mathrm{n}\mathrm{t}\p…
The morphology of potassium hydrogen tartrate (KHT) crystals precipitated from ethanol-water solutions and from white wines from the Penedes (Spain) is reported. In each case, the rate of precipitation is influenced by agitation, supersaturation, and temperature. Precipitation of KHT from wines differs from that from…
Au cours de l'affinage des fromages pte molle de type Camembert, certains minraux migrent de l'intrieur vers l'extrieur de faon irrversible. Ainsi les teneurs en calcium et magnsium de la crote en fin d'affinage sont respectivement de 16,7 g/ kg et de 521,9 mg/kg alors que celles du centre sont de 0,92 g/kg et de 72,5…
Co-condensation of silver atoms with monomeric SiO and an excess of argon yields Ag(SiO) and probably Ag2(SiO), identifiable by their i.r. spectra; 28,29,30Si and 16,18O isotopic shifts imply not a linear but a triangular structure for Ag(SiO) with ∠ AgSiO ⩽ 90°
The birefringence of mixtures of homologues from the terminally non-polar series of p,p′-dialkylazoxybenzenes has been studied. The birefringence is used as a probe of the orientational order parameter, which is coupled to the translational (smectic) order parameter. The tricritical nematic to smectic-A point which re…
Classical levitation melting process using conventional conical inductcr can not be used at industrial scale because of the limited size of liquid metal which can be maintained in equilibrium against gravity force. Because of high frequency and axisymmetry of magnetic field distribution, a stagnation point occurs at t…
Article The Hot Pressing of Dry-formed Wood-based Composites - Part I. A Review of the Literatlire, Identifying the Primary Physical Processes and the Nature of their Interaction was published on January 1, 1988 in the journal Holzforschung (volume 42, issue 6).
Five types of collagen with triple-helical regions approximately 300 nm in length were found in lamprey tissues which show characteristic D-periodic collagen fibrils. These collagens are members of the fibril forming family of this primitive vertebrate. Lamprey collagens were characterized with respect to solubility,…
Abstract The basic premise underlying the use of the scanning electron microscope (SEM) for linewidth metrology in semiconductor research and production applications is that the video image acquired, displayed, analyzed, and ultimately measured accurately reflects the structure of interest. However, it has been clearl…
Reaction in water of Cu(pdto)(ClO4)2 with Li(TCNQ)/TCNQ mixtures yields solid crystalline materials of formulae Cu(pdto)(TCNQ)x(x= 2, 2.5, or 3) which display high electrical conductivities; reaction of Cu(pdto)(ClO4) with Li(TCNQ) yields Cu(pdto)(TCNQ), a poor conductor which has been shown by X-ray crystallography t…

The physicochemical properties of a calcium-binding protein (CaBP) isolated from rat liver cytosol was investigated. Isoelectric focusing in a polyacrylamide gel plate using the Broad pI Calibration Kit showed that the isoelectric point is 5.20. The ultraviolet (UV) absorption spectrum of CaBP showed a maximum at 278…
In order to make a quantitative description of the plastic deformation of polycrystalline alloys governed by the stress induced martensitic transformation (SIM), the condition of yield by SIM is formulated for multiaxial stress states. The relation between the plastic strain of a crystallite and the volume fractions o…
Pulsed-dye laser excitation and lifetime spectroscopy of the 7F0----5D0 transition of Eu3+ reveals details of the binding of this ion to the calcium-binding sites of calmodulin (labeled I-IV, starting at the N-terminus). For 10 microM calmodulin Eu3+ binds quantitatively at sites I and II and more weakly at sites III…
