    Notes:
    Sharp and straight step edges on (001) LaAlO3 (LAO) substrates were ion milled by using an electron beam defined amorphous carbon thin film mask. YBa2Cu3O7 (YBCO) thin films patterned to narrow strips across the step edges gave high quality Josephson junctions. Their current–voltage (I–V) curves could be well described by the resistively shunted junction model with or without excess current. By varying the YBCO film thickness over a fixed step height, the critical current density (jc) of the junction could be changed by several orders of magnitude. For junctions with high jc, typical IcRn (product of critical current and normal resistance) values of around 100 μV at 77 K and more than 1 mV at 4.2 K were obtained. Some excess current was observed. For junctions with low jc, the dependence of Ic on an applied magnetic field was strong even at low temperatures. The Ic showed a main peak in the center and well-defined periods as a function of applied magnetic field. The minimum Ic value suppressed by the magnetic field was about 20% of its maximum value at 4.2 K. Junctions with low jc usually showed hysteretic I–V curves at low temperatures. The McCumber constant βc fell in the range of 0.8–2. Fiske and flux-flow resonances were observed for some junctions. The shunting capacitances of the junctions were estimated from the McCumber constant βc, Fiske resonances, and flux-flow resonances. A shunting capacitance value per unit area of 12–35 fF/μm2 was obtained. High resolution cross-sectional transmission electron microscopy was used to study YBCO films grown across straight and wavy step edges. Two 90° tilt boundaries were formed at the edge of a step. The top and bottom YBCO films had their c axis oriented normal to the (001) plane of LAO. In the edge region, the c axis of the YBCO film was tilted by 90°, the a axis was normal to the (001) plane of LAO, and the b axis was lying along the step edge. For wavy step edges, second phase particles usually appeared in the YBCO film along the step edge region. Defects were found on the surface of the LAO substrate along the wavy step edge region. These defects might act as nucleation centers for the second phase particles in the YBCO film. © 1996 American Institute of Physics.

    Notes:
    Springs for scanning force microscopy (SFM) are described which incorporate two separate advances: Their shape significantly reduces the effect of photon shot noise in the optical beam deflection method, and they are endowed with very sharp tips through a unique process based on controlled fracture of micromachined structures. With this readout method, the noise in the measured tip position is limited by photon shot noise, which is proportional to the ratio of the effective length of the spring to the length of the mirror. Cantilever springs optimized for this parameter are described, with a measured white noise level of 29 fm/(square root of)Hz at 210 μW of laser power; torsion springs for which the mirror length exceeds the effective length yielded a theoretical noise level of 7.2 fm/(square root of)Hz at this power. Cantilever springs optimized for this parameter are described, with a measured white noise level of 29 fm/(square root of)Hz at 210 μW of laser power; torsion springs for which the mirror length exceeds the effective length yielded a theoretical noise level of 7.2 fm/(square root of)Hz at this power. The latter is lower than the noise of an ideal fiber interferometer at the same power, demonstrating that the optical-beam-deflection method can be made competitive with interferometric methods for noise-critical SFM applications. This novel tip making technique generates cube-corner-shaped tips, with a radius which is unresolvable in scanning electron microscope images, implying that it is less than 10 nm. These tips are intended for samples whose features are in the size range 0.5–20 nm, where the tip curvature is the resolution limiting factor. To demonstrate their performance in this regime, the tips were used to image single collagen molecules.

    Notes:
    The microstructure of YBa2Cu3O7−δ(YBCO) grain boundaries obtained at step edges on (001) LaAlO3 substrates have been studied by scanning and transmission electron microscopy. A typical morphology of the YBCO grain boundaries is distinguished by two parts where the parts are expected to have different junction properties. One part of the boundary is caused by the difference in nucleation probability between the (001) surface and the inclined step facet. The second morphology is developing as a result of minimization of the YBCO surface energy. © 1997 American Institute of Physics.

    Notes:
    The inheritance of seedling resistance to a Swedish isolate of Pyrenophora teres f. teres was investigated in four resistance sources of spring barley. Accessions CI 2330, CI 5791, CI 5822 and CI 9779 were used as resistance sources, and the cultivar ‘Alexis’ was used as a susceptible parent in different crosses. From the disease reaction in the F1, F2 and F3 generations it was concluded that the resistance was governed by the same two complementary genes in CI 5791, CI 822 and CI 9776. One of these genes was present in CI 2330. The first three cultivars were highly resistant to the isolate used in this investigation. These results, when combined with earlier studies, suggest that CI 5791, CI 5822 and CI 9776 may be of great value as sources of resistance to barley net blotch. Spearman's rank correlation between the disease reaction of F2 plants and their F3 progeny was highly significant (r = 0.75; P ≥ 0.001) It is suggested that selection in the F2 generation is effective. In a backcross breeding scheme, single plant reactions in F1 or F2 need to be confirmed in later generations.

    Notes:
    The effects of the phytotoxin prehelminthosporol from the fungal pathogen Bipolaris sorokiniana on the activities of the plasma membrane H+-ATPase, Ca2+- ATPase, and 1, 3-β-glucan synthase in barley roots were investigated in vitro. Plasma membranes were isolated by aqueous polymer two-phase partitioning. Proton pumping by the H+-ATPase was drastically reduced in a dose-dependent manner, with complete inhibition at 500 μM prehelminthosporol, while inhibition of ATP hydrolysis was less drastic, with a 35% inhibition at 500 μM toxin. Ca2+ uptake was also reduced, although to a lesser extent than proton pumping, with a maximal inhibition of 60% at 500 μM toxin. The 1, 3-β-glucan synthase activity was weakly stimulated at toxin concentrations below 100 μM, with higher concentrations being inhibitory. Taken together, our results indicate that prehelminthosporol exerts its effect in at least two ways. First, it appears to disrupt the membrane barrier and thus seriously interfere with establishment of the proton gradient that drives ion and nutrient uptake and affect the efflux of Ca2+ to maintain the low cytoplasmic concentration of Ca2+ essential for the function of Ca2+ as a messenger in signal transduction. Secondly, it appears to inhibit the enzyme activities. The 1, 3-β-glucan synthase is activated by Ca2+ and can operate in the presence of low concentrations of prehelminthosporol (which may induce Ca2+ leakage into the cytoplasm and hence activate the enzyme), to produce callose to seal leaky membranes.

    Notes:
    The effects of 5 mg slow-release terbutaline sulphate tablets (Bricanyl® Depot) given twice daily were compared with those of ordinary oral β-agonist treatment given three times daily. The study was open, randomized and cross-over and was carried out over 8 weeks in 18 children with bronchial asthma. Compared with ordinary medication, the slow-release tablets obtained higher morning expiratory peak flow values and an improvement in the asthma symptoms during the night and during exercise (P 〉 0.05). No differences were found in side effects in spite of a higher total daily dose during the period with terbutaline slow-release tablets. The slow-release tablets were preferred by 15 of 18 children and their families when the effects, side effects and dosage were evaluated.
