  • In the late 1980’s, a considerable amount of research addressing the effects of acidic deposition was begun, much of it related to the Congressionally mandated National Atmospheric Precipitation Assessment Program (NAPAP). As a result of the 10-year NAPAP program, effects on human health, materials, structures, visibility and terrestrial and aquatic ecosystems were evaluated. As a result of NAPAP funded research, negative effects of acidic deposition were documented on freshwater lakes in the Adirondacks and on the red spruce of the Adirondacks and northern Appalachians....

  • Trees as high as 25 - 30 m, small branches, self-pruning well, easy to grow by seed, long life, nitrogen fixation. Can grow on various soils, including poor soils, poor drainage. Grows fast, high-speed growth in the first few years. Song on a place if planted several consecutive cycles can lead to poor potassium and magnesium in the soil. Pit wood, pulp (wrapping paper), chipboard and wood stem as well due to the high heat of coal. In silvicultural crops used as the supporting soil improvement, shade....

  • Purified recombinant proteins fromSynechocystisPCC6803 were used to show that the magnesium chelatase ChlH subunit stimulates magnesium protoporphyrin methyltransferase (ChlM) activity. Steady-state kinetics demonstrate that ChlH does not significantly alter theKmfor the tetrapyr-role substrate. However, quenched-flow analysis reveals that ChlH dramat-ically accelerates the formation and breakdown of an intermediate in the catalytic cycle of ChlM.
