Craigie reported for the first time the occurrence of heterothallism in a rust fungus, Puccinia helianthi Schwein.,2) and stated that when two basidiospores of opposite sex, "+" and "-", are sown close together on a sunflower leaf so that the pustules arising from the two infections soon coalesce, the two monosporous mycelia come into contact, fuse together, and give rise to normal binucleate a...

“Inducibility” of amylase in Drosophila melanogaster was defined and investigated in a natural population from Japan. Inducibility represents the effects of factors remote from the structural gene that control the amount of enzyme produced. Inducibility of an isogenic line is measured as the ratio of the enzyme’s specific activity in two different inducing environments. There was considerable g...

Knowledge of the dynamic performance of turbopumps is essential for the prediction of instabilities in hydraulic systems; the necessary information i s in the form of a transfer function relating the instantaneous pressures and mass flow rates at inlet and discharge. Cavitation has a significant effect on this transfer function since dynamical changes in the volume of cavitation contribute to t...

Using a new tool developed in our laboratory to quantify local pressure changes on an artificial spinal cord, quantitative results correlating fracture/soft tissue pathology with cord pressure changes, was accomplished. Human cadaveric head-neck complexes were dynamically loading by fixating the inferior of the preparation and removing the cadaver spinal cord The instrumented artificial spinal ...

-The development of the ALOHA system packet broadcasting network at the University of Hawaii illustrates a number of general principles about the relationship between information theory and the design of real information systems. An anecdotal account is given of the development of the ALOHA system, emphasizing the interaction of the theory and the design of the experimental network. In addition...

we shall extend the results of [5] and prove that if f = z o a x ? z [[x]] is algebraic over q (x), where a = 1, ƒ 1 and if ? , ? ,..., ? are p-adic integers, then 1 ? , ? ,..., ? are linkarly independent over q if and only if (1+x) ,(1+x) ,…,(1+x) are algebraically independent over q (x) if and only if f , f ,.., f are algebraically independent over q (x)

For thirty years the study o f Quantitative Structure Activity Relationships (QSAR) has been an active area o f research aimed at developing an understanding o f the interactions be­ tween inhibitors o f photosynthetic electron transport and the herbicide binding site in the Pho­ tosystem II (PS II) reaction centre. Many QSAR studies o f PS II inhibitors with diverse chemi­ cal structures have ...
