With potassium ferricyanide copper(II) forms KCu(10),[Fe(CN)(6)](7) quantitatively in 0.5M potassium nitrate medium. Cadmium forms Cd(3)[Fe(CN)(6)](2) if the ferricyanide is added to the cadmium solution in absence of extra potassium, and KCd(10)[Fe(CN)(6)](7) if potassium is added first, or if the cadmium solution is added to the ferricyanide. Silver forms(More)
A new, highly stable uranium stain, which allows very simple, ultra rapid staining procedures for routine electron microscopy of ultrathin sections, is presented. The advantages of the new staining procedures, in comparison with the most conventional ones, employing lead citrate, are illustrated and discussed.
Advances in remote sensing technology are now providing tools to support geospatial mapping of the soil properties for the application to the management of agriculture and the environment. In this paper results of visible and near IR spectral reflectance are presented and discussed. A supportable evaluation of organic matter in the soil is the absence of a(More)
Data are presented relating conventional transmission electron microscope (CTEM) ultrastructural observations of the monomeric phenotypic variant (Hp 1-1) of the haptoglobin class of blood glycoproteins. Through comparison of these findings with homologous published data, obtained by means of scanning transmission electron microscopy (STEM), the validity of(More)
In the current program for the preparation of an urban air map, this paper reports data obtained by the five base stations in the period 1997-2000 regarding traditional pollutants and gives the first results obtained in determining continuously benzene, toulene and PM10. Additional measurements have been carried out by a mobile station at the falcate zone,(More)
The stoichiometry of the reaction between ferrocyanide and thorium, neodymium, uranyl ion and mercury(II) has been investigated. The first three give single products irrespective of the order of addition of the reagents, but the last does not. If mercury(II) is added to ferrocyanide Hg(2)Fe(CN)(6) is obtained, but if ferrocyanide is added to mercury(II)(More)
New preparative methods have been devised which allow electron microscope observation of T-even head substructure, under conditions of negative staining. Capsomeric constitution of the head shell could so be confirmed and demonstrated for T2 and T4. In addition capsomere size and shell thickness of the head of both phages have been determined and the(More)
