    Notes: Mono- and polycrystalline Ni films, ranging in thickness from 19 to 382 nm, have been produced by vacuum deposition on (001) monocrystalline Ag/NaCl and on glass substrates, respectively. Subsequently, saturation magnetization Ms, magnetogyric factor γ/2π, and effective uniaxial anisotropy Hk were measured by a combination of vibrating sample magnetometer and ferromagnetic resonance (FMR), and corresponding internal stress σ was measured by a levered optical beam reflection technique. In addition, the microstructure of both mono- and polycrystalline films has been characterized by conventional and cross-section transmission electron microscopy. Saturation magnetization can be interpreted by the presence of a magnetic dead layer of about 9 nm and a constant value of 434 emu/cm3, thereafter. Results from FMR can be described by contributions from shape and stress-induced anisotropy. Corresponding values of σ, as computed from Hk, are in satisfactory agreement with values measured by the optical beam reflection technique and yield values of about 1010 dyn/cm2; σ generally decreases with increasing film thickness and annealing time and temperature. Finally, monocrystalline films are characterized by a single FMR peak; polycrystalline films thicker than about 200 nm are characterized by multiple peaks. Occurrence of these multiple peaks is attributed to variation in the effective magnetoelastic constant as a result of a change from equiaxed to columnar grain morphology.

    Notes: Finite displacements of Bloch lines, induced by current pulses directly traversing the sample, have been observed by the ferrofluid technique in Ni81Fe19 films of thickness 33–68 nm containing cross-tie domain walls. The pulses of duration ≤ 1 μs are normal to the wall. Bloch lines move along the wall whenever the current density exceeds a critical value ≈1×1012 A/m2. It is possible to partly control the sense of the central spin of Bloch lines by applying a field μ0H≈100 μT normal to the film during Bloch-line creation. The sense of the current-induced force on Bloch lines is found to depend on the sense of the central spin of Bloch lines, and agrees with the sense of the theoretically predicted s-d gyroscopic force which arises from s-d exchange. However, the average value of the force is about four times smaller than the predicted value for a one-band model.

    Notes: Abstract An investigation has been carried out into the effects of 0.1 to 1.0% HCl onthe oxidation of Fe–28%Cr and Fe–28%Cr–1%Y inargon–20%O2 at 600 and 700°C. At the higher temperature,the additions of HCl to the gas caused considerable increases in corrosionof the binary alloy, with the rates of metal loss actually being greaterthan those of iron in the 0.5 and 1% HCl-containing environments. Thick andmultilayered scales were observed; these were oxides, particularlyFeCr2O4 and Fe2O3, that developedfollowing formation and vapor phase transport of chlorine-containing speciesfrom the metal surface. The main metal-loss processes were evaporation ofFeCl2, CrCl2, and CrO2Cl2, withthe first two of these reacting with oxygen to form solid oxides in thescale, while the third was lost mainly to the environment. The addition of1% Y to the alloy resulted in a marked improvement in corrosion resistanceat 700°C, because of the reactive element facilitating rapidestablishment of a protective Cr2O3-rich layer andpromoting the formation of condensed chlorides rather than the more volatileCrO2Cl2 phase. At 600°C, additions of HCl toargon–20%O2 caused formation of some localized condensedchlorides on both alloys, but the corrosion rates were relatively low,because of protection by a Cr2O3-rich oxide scale.

    Notes: Abstract Suspension-cultured rice cells growth was markedly inhibited and ammonium content increased when rice cells were deprived of phosphate. When rice cells were cultured at increasing concentrations of ammonium chloride, ammonium content increased, however, no significant inhibition of cell growth was observed. Addition of D-arginine, an inhibitor of putrescine biosynthesis, resulted in a complete recovery of growth in rice cells under phosphate deprivation, but did not decrease the content of ammonium. Our results indicate that the growth inhibition induced by phosphate deprivation is not associated with ammonium accumulation.

    Notes: Abstract The effects of methyl jasmonate (MJ) and abscisic acid (ABA) on some physiological processes of rice were compared. MJ exhibited ABA-like effects by promoting senescence of detached leaves, by inducing acid phosphatase activity of detached leaves, by inhibiting ethylene production and shoot growth of seedlings, as well as inhibiting callus formation from anthers. However, MJ and ABA had opposite effects on 1-aminocyclopropane-1-carboxylic acid-dependent ethylene production in detached leaves. The regeneration ability of anther-derived callus was inhibited by MJ but not by ABA. MJ but not ABA markedly induced peroxidase activity in senescing detached leaves. It is concluded that not all physiological processes of rice affected by MJ are similar to those by ABA.

    Notes: Abstract Wick tensors are used to describe homogeneous chaos and to define multiple Wiener integrals. The Wiener–Itô decomposition is expressed by the formula $$\varphi (x) = \sum\limits_{n = 0}^\infty {\frac{1}{{n!}}\int_B {[D^n (\mu \varphi )(0)]^ \sim}} (x + iy,...,x + iy)d\mu (y)$$ . We use this formula to interpret Hida's original idea of generalized multiple Wiener integrals as generalized functions acting on the space of test functions.

    Notes: The purpose of this research is to prepare high solute permeability membranes for hemodialysis by plasma depositing hydrophilic monomers onto chemically treated or O2 plasma etched Nylon 4 substrate. The factors that affect the performances of membranes, such as deposition conditions and chemical or plasma etching conditions, were studied. The monomers used in this study were 1-vinyl-2-pyrrolidone (VP), 2-Hydroxyethyl methacrylate (HEMA), and Methyl methacrylate (MMA). The permeabilities of NaCl, urea, vitamin B12, and albumin were measured, as were the water content, hydration, diffusivity, partition coefficient, and protein adsorption ratio of fibrinogen to albumin by membrane surface of plasma deposited membranes.The permeabilities of NaCl, urea, vitamin B12, and albumin of HEMA 5 w-1 h plasma deposited onto chemical treated Nylon 4 membranes were 2.896 ± 0.192, 3.301 ± 0.325, 0.010 ± 0.007, and 0.000 x 10-5 cm2/min, respectively. The mole ratio of adsorbed fibrinogen to adsorbed albumin (F/A) is 0.26 ± 0.05, which is much lower than that of the pure Nylon 4 membrane (0.94 ± 0.06) and the Gambro® membrane (0.90 ± 0.15). The HEMA deposited membrane possesses the highest feasibility as hemodialysis material among those plasma deposited membranes considered.
