Equations used to develop the CO2 -Ca-pH relationships in calcareous soils are reviewed. The equation Pco, (Ca) --(H) 2 Ke , is used to draw a three-dimensional surface and to derive three partial differential equations to illustrate the relationships between CO 2 partial pressure, Ca activity and pH. lc is a combination of Henry's Law constant, the first and second dissociation constants for c...

-Two mutually exclusive views exist concerning the relative stabilities of gibbsite and boehmite in soils. These are examined in terms of experimental and thermodynamic evidence and it is shown that all three possible divariant assemblages of two phases that can exist between gibbsite, beohmite and H20, may do so at 25~ and 1 atmosphere total pressure depending on the status of HeO. It is furth...

the reaction of barium chloride with 2, 6-pyridinedicarboxylic acid in water led to the formation of a novelpolymeric complex formulated as {[ba2(hpydc)2(pydc)(h20)3].h20.(h2pydc)}.(i). the crystal structure of (i)was characterized by single crystal x-ray diffraction method. the complex was crystallized in the monoclinicsystem with space group p2/c, with four molecule in unit-cell, e.g z=4. the...

Changes in water content and dry weight were determined in control cells and those induced to cold harden in response to abscisic acid (ABA) treatment (7.5 x 10-5 molar). Bromegrass (Bromus inermis Leyss cv Manchar) cells grown in suspension culture at room temperature (230C) for 7 days acclimated to -28°C (LT50) when treated with ABA, or to -50C when untreated. ABA significantly reduced cell g...

Chapter 1. Magnesium-dependent phosphate ester processing enzymes frequently employ a carboxylate-bridged dimetallic unit in their active sites. Biomimetic modelling chemistry of these magnesium centers has not been investigated previously. An brief introduction of the enzyme systems is presented, along with the focus of the present work. Chapter 2. Several dimagnesium(II) complexes were synthe...

The coordination of the electronic ground states of Fe+ (6D) and FeO+ (6x+) has been investigated in the gas phase with the inorganic molecules H2, HD, D2, H20, CO, NO, N2, 02, C02, N02, and N20. Reaction rate coefficients and product distributions were measured with the Selected-Ion Flow Tube (SIFT) technique operating at 294 f 3 K and a helium buffer-gas pressure of 0.35 f 0.01 Torr. Except w...

Sulfur chemistry lIas been incorporated in the National Center for Atmospheric Research Community Climate Model in an internally consisterlt manner with other parameterizations in the nlodel. The model predicts mixing ratios of dimethylsulfide (DMS), S02, SO~-, H20 2. Processes tllat control the mixing ratio of these species include the emissions of DMS aIld S02, transport of each species, gasa...

We present a new method based on information theory to find the optimal number of bands required measure physical properties galaxies with desired accuracy. As proof concept, using recently updated COSMOS catalog (COSMOS2020), we identify most relevant wavebands for measuring in Hawaii Two-0 (H20)- and UVISTA-like survey sample $i<25$ AB mag galaxies. that available $i$-band fluxes, $r$, $u$, I...

We consider a broad class of intertemporal economic problems and characterize the short-run long-run responses demand for good to permanent increase in its market price. Depending on interplay between self-productivity time discounting, we show that dynamic substitution effects can generate price elasticities opposite signs short run long run.
