    Notes: Abstract Apparent molal volumes and compressibilities are reported for dilute aqueous solutions of cyclic ethers, simple carbohydrates, and related polyhydroxy compounds. The results for carbohydrates are considered in the light of two theoretical descriptions of such systems, i.e., the semiideal solution approach of Stokes and Robinson, and the McMillan-Mayer theory ty[e of approach as employed by Kozak, Knight, and Kauzmann. It is concluded that neither model is satisfactory, and that for these solutions a specific hydration model, described in more detail in another paper, is more satisfactory.

    Notes: Abstract The design, configuration and operation of Ti:Sapphire-laser-pumped femtosecond Optical Parametric Oscillators (OPOs) using KTP and RTA are described. The results presented include configurations capable of producing transform-limited pulses shorter than 40 fs and operating with pump powers as low as 50 mW. Tunability within the 1–3 µn spectral region is demonstrated using pump-tuning alone.

    Notes: Abstract Decapitation, gibberellin A3, high light, their combination, and certain levels of indole-3-acetic acid increase ethylene evolution and also induce branch hyponasty (upturning) in seedlings of Cupressus arizonica Greene, the increase in ethylene preceding obvious hyponasty. Exogenous ethylene also causes branch hyponasty and branches of seedlings maintained in an atmosphere scavenged of ethylene by mercuric perchlorate grow downwards. It is concluded that ethylene may play a role in the apical control of branch angle in some conifers. The positive effect of ethylene in increasing branch hyponasty may be direct, or reflect changes in levels of endogenous auxin and/or gibberellin.
