Synthesis and molecular structure of the eight-coordinate complex bis( 4-amino-N,N’-disalicylidene- 1,2-phenylenediaminato)zirconium( IV), a new reagent for preparing coordination polymers
(The American Chemical Society: Inorganic Chemistry, 1987-12-30)
The precursor complex bis(4-nitro-N,N’-disalicylidene- 1,2-phenylenediaminato)zirconium(IV);Zr(ndsp)2, was synthesized from the appropriate Schiff-base ligand and zirconium tetra-n-butoxide butanol complex (2:1, respectively) ...

Comparison of the mid-frequency line edge noise algorithms of Jim Hamerly and Yigal Gur for the best correlation to the psychophysical defect known as raggedness
(1987-08-12)
A study was conducted to compare the mid-frequency line edge noise
algorithms of Jim Hamerly and Yigal Gur. Comparisons were made to
determine which algorithm correlated best with the psychophysical defect
known as ...
The ecological cost of morphological specialization: feeding by a fossorial lizard
(Springer: Oecologia, 1987-08)
Head size and shape of reptiles may reflect selection for multiple uses. For example, sexual selection for large head size may enhance feeding efficiency. In contrast, morphological characteristics of the heads of fossorial ...
An azophenolic colorimetric reagent for use in enzyme-linked immunosorbent assays.
(Elsevier: Analytical Biochemistry, 1987-08-01)
A colorimetric reagent, 4-(4'-nitro-2'-methylsulfonylphenylazo)phenyl phosphate (NMPP), has been shown to be an effective substrate of alkaline phosphatase. NMPP and p-nitrophenyl phosphate were applied in comparative ...
Electrochemical oxidation and reduction of methylene-bridged complexes of manganese, cobalt, and rhodium
(The American Chemical Society: Organometallics, 1987-08)
The oxidation and reduction of a series of alkylidene-bridged dimetallic compounds containing Mn, Co, or Rh have been studied by electrochemical and spectroscopic techniques. Oxidation results in production of a cation ...
The abundance of salamanders in forest stands with different histories of disturbance
(Elsevier: Forest Ecology and Management, 1987-07)
Because of the importance of salamanders in forest food chains, the effects of forest management practices on populations of these animals warrant consideration. We compared the numbers and activity patterns of salamanders ...
High resolution X-ray fluorescence spectroscopy : A potentially useful technique for chemical bonding studies in fossil fuels
(Elsevier: Fuel, 1987-07)
The high resolution oxygen (O-K) and carbon (C-K) X-ray fluorescence spectra of coals were taken on a 5 metre grating X-ray spectrometer. A comparison of the C-K spectra of a North Dakota lignite (Beulah) and a Utah ...
