Application of 15 kg Borax/ha resulted in the lowest incidence of browning, maximum number of siliqua per plant, number of seeds per siliqua and total seed yield. Among the molybdenum levels, 1.0 kg Sodium molybdate/ha recorded the maximum number of leaves, primary branches, siliqua per plant, length of siliqua and total seed yield while the highest plant height, leaf size index number of seeds per siliqua, seed yield, least number of days to bolting and minimum incidence of whiptail were recorded with 1.5 kg Sodium molybdate/ha. Combined application of 10kg Borax with 1.0kg Sodium molybdate/ha gave highest cost: benefit ratio of 1:5.16.

This allergen (Pol) was found in the fraction which precipitates between 70 and 100% ammonium sulphate saturation. Pol showed a molecular weight of 15,000 daltons as determined by SDS-PAGE and HPLC. The pI of Pol was in the pH region 4-6, IEF showing four major bands. Two major bands were shown by CIE, CRIE and immunoblotting; major contaminants or aggregates were also revealed by the latter technique and by HPLC. Pol showed an allergic specific activity 2 times higher than the crude extract; moreover it was shown to be a major allergen since it inhibited 29 out of 30 sera from allergic patients sensitive to P. officinalis.

Essential features of the structures of the adsorbents have been characterized by analysis of nitrogen adsorption/desorption isotherms and by both direct and indirect electron microscopy.Heats of adsorption of 423 °K for adsorbed amounts of 0.1 µmol m−2 were 48.0, 59.0, and 85.0 kcal mol−1 for the 500, 700 and 900 °C samples, respectively. The values for the 500 and 700 °C samples fell rapidly with increasing coverage to around 19.0 kcal mol−1 at 3.2 to 3.3 µmol m−2, while the values for the 900 °C sample decreased slowly to 15.0 kcal mol−1 at the same coverage.The pores had circular cross sections and mean diameters of 25, 35, and 40 Å were observed for the 500, 700, and 900 °C samples, respectively. Examination of carbon/platinum replicas of the surface showed the presence of agglomerates of spherical pa...

As metal is removed, the natural frequency of the cylinder slowly decreases, thus decreasing the number of surface waves accommodated around the circumference. The pattern repeats itself each time the number of surface waves per revolution is decreased by one. The slow rise and fall of vibration intensity depends in the main on the interaction of part of the cutting tool with the surface waves cut during the previous revolution.

One effect is that down-chirp filters have lower loss than up-chirp filters, which is shown to be caused by asymmetric phasing of reflections by near-synchronous electrodes. The most prominent effect is large amplitude ripple in the passband of broadband down-chirp mters, occurring at frequencies above the second harmonic of the synchronous frequency of the lowest-frequency electrodes, and caused by surface wave reflections by electrodes with a synchronous frequency that is half the operating frequency. The large amplitude ripple is halved in nondispersive chirp filters and does not occur in up-chirp filters. A further effect is enhanced triple-transit ripple, which is also due to "second harmonic" reflections, and occurs in both up-and down-chirp filters. A design procedure that suppresses the large amplitude ripple is described and is found experimentally to be effective. Relations are given for the estimation of directionality, and single and triple transit ripple amplitudes due to second harmonic reflections, for chirp filters with arbitrary chirp law, bandwidth, and dispersion time. T I. INTRODUCTION HE PERFORMANCE of surface-acoustic-wave (SAW) chirp transducers on piezoelectric substrates with high electroacoustic coupling is affected in several ways by electrode reflectivity. Reflections by electrodes arise from two effects: the mass-loading of the surface and the shorting of the electric field associated with the SAW. On high-coupling substrates used for wideband transducers, it is the latter effect that dominates, causing changes in the SAW velocity and acoustic impedance, which are proportional to the coupling strength. To account for the effect of reflections, Smith et al. [l] extended the crossed field circuit model to include an acoustic wave impedance difference between regions with and without electrodes. They found that electrode reflections 1) introduce acoustic directionality, which causes dispersive down-chirp filter configurations to have lower insertion loss than up-chirp configurations; 2) increase the level of the triple transit ripple; and 3) contribute additional passband ripple, which has a smaller amplitude than that caused by triple transits. Other considerations for SAW chirp transducer design, particularly important for large time-bandwidth products, are described by Gerard et al.
