The Motorola MC68020 and MC68030 Microprocessors
(Prentice-Hall, 1989)
This book is organized into five parts, as indicated in the Chapter Descriptions in this preface. The first four chapters present the MC68020 family to the reader. These chapters also introduce microcomputers and computer ...
Semaphore Solutions To General Mutual Exclusion Problems
(University of North Texas, Denton, 1988)
Automatic generation of starvation-free semaphore solutions to general mutual exclusion problems is discussed. A reduction approach is introduced for recognizing edge-solvable problems, together with an O(N^2) algorithm ...
Using the game Cube-4 as an example in an introductory artificial intelligence course
(SIGCSE Bulletin, 1989-09)
No abstract available.
Starvation-Free Solutions of Mutual Exclusion Problems Using Semaphores
(Proceedings of the ACM South Central Regional Conference, 1987-10)
The standard implementation of mutual exclusion by means of a semaphore allows starvation of processes. Between 1979 and 1986, three algorithms were proposed that preclude starvation. These algorithms use a special kind ...
Effects of Chromium on Nodulation and Nitrogenase Activity of Soybean (Glycine Max L)
(China Environmental Science, 1988)
Currently, the mechanisms underlying the effects of nitrogen on nodulation and nitrogen fixation of leguminous plants remain uncertain. To further investigate the relationship between nitrogen with nodulation and nitrogen ...
Effect of Trivalent and Hexavalent Forms of Chromium on Soybean Growth
(Agro-Environmental Protection, 1988)
DNA synthesis in chloroplasts. III. The DNA gyrase inhibitors nalidixic acid and novobiocin inhibit both thymidine incorporation into DNA and photosynthetic oxygen evolution in isolated chloroplasts
(Journal of Experimental Botany, 1989)
The influence of two DNA gyrase inhibitors, nalidixic acid and novobiocin, on DNA synthesis in isolated pea chloroplasts was examined. Novobiocin at 1–5 mol m−3 markedly lowered [3H]thymidine incorporation into DNA (30–95% ...
DNA synthesis in chloroplasts. I. Characterization of and developmental variation in both light- and ATP-driven thymidine incorporation by isolated intact chloroplasts
(Journal of Experimental Botany, 1988)
Intact chloroplasts from young pea leaves were able to incorporate [3H]thymidine into DNA at relatively high rates (50 pmol mg-1 chlorophyll h-1 or more), using light as the sole energy source. The intact plastids were ...
DNA biosynthesis in chloroplasts and its regulation: Studies on isolated chloroplasts and chloroplast extracts
(Progress in Photosynthesis Research, 1987)
During leaf development, chloroplasts are formed by the binary fission of pre-existing plastids (1); thus, replication of chloroplast DNA (ctDNA) must occur to maintain an adequate amount in each organelle. The levels of ...
DNA synthesis in chloroplasts. II. Developmental variation in TTP incorporation into DNA by plastid extracts
(Journal of Experimental Botany, 1988)
Incorporation of [3H]TTP into DNA by pea chloroplast extracts was highly dependent on the age of the tissue from which plastids were prepared. Catalytic activity was greatest in samples from 6- to 9-d-old plants; preparations ...
