Human lymphocytes were labeled with biotinylated anti-lymphocyte-directed monoclonal antibodies, to which streptavidin and subsequently biotinylated dextran-magnetite particles were coupled. This labeling resulted in a strong and selective negative contrast enhancement of lymphocyte suspensions at 2.0 T, caused predom…

Viscosity of Simple Soda‐Silicate Glasses, 500° to 1400°C Comparison of the results given by English with those of Washburn, Shelton and Libman, indicates a discrepancy in the absolute values of log 10 viscosity amounting to 0.6, those of Washburn et al. , being relatively too high. If correction for this is made, the…

TABLE 2 (continued) Complex Organic ligand(s) Ref.
The 18 vibrational modes expected from group-theoretical analysis have been obtained in the polarized Raman spectra of ${\mathrm{ZnWO}}_{4}$ single crystals. The six internal modes of the ${\mathrm{WO}}_{6}$ octahedra have been assigned. The temperature dependence of the frequencies and linewidths of the internal mode…

The conductivity relaxation phenomenon in glassy and crystalline ionic conductors has been known for many years to be a highly nonexponential process. The stretched exponential function exp-(t/\ensuremath{\tau}${)}^{\mathrm{\ensuremath{\beta}}}$ has been used with varying levels of success to describe this relaxation.…

A poly(o‐phenylenediamine)(PoPD)‐film‐coated electrode had electrochemical responses only to two halogenide ions, I − and Br − , while it had no responses to other inorganic ions examined. In this case, the film was found to be permeable to the ions. The permeability of the ions was controllable by incorporating quino…
1. Stress analysis using modern computer modelling techniques indicated that the shell should fail in tension as a result of the accumulation of stress at its inner most surface with the characteristic notched appearance of the mammillary layer providing the ideal crack initiation site. 2. Practical observations howev…
A parently, certain single crystals do not obey Schmid's law for slip on individual systems. For example, many intermetallic compounds such as Ni 3Al with the LI 2 structure display yield behaviors that are called “anomalous” in the sense that the critical resolved shear stress on the primary slip system at yield is a…
Abstract The weathering of a trioctahedral mica (phlogopite, 2–100‐µm particle size) was investigated in the rhizosphere of ‘Turilo’ Italian ryegrass ( Lolium multiflorum Lam.). A special culture vessel made it possible to simulate a one‐dimensional macroscopic rhizosphere by developing a root mat on a polyamide net.…
The database on structural phase transitions is presented in the simple and easy accessible form of table. The symmetry changes and temperature for 3446 phase transitions and the references for each of 2242 registered crystalline materials with well defined stoichoimetry are the main data in this table. The rules for…
Deformation behavior of Ni2MnGa single crystals uniaxially loaded in compression and tension along the 〈100〉β1 and 〈110〉β1 axes were investigated. It was shown that three successive stress-induced structural transitions may be observed for specimens tensed along the 〈100〉β1 or compressed along the 〈110〉β1 direction, w…
Abstract Carbon black N110 and a precipitated silica, which have comparable surface area and structure, were selected as model fillers to study the effect of filler surface energies on rubber reinforcement. In comparison with carbon black, the surface energies of silica are characterized by a lower dispersive componen…
