Explants of muscular and adipose tissue embedded in a three-dimensional matrix of fibrin or collagen fibrils give rise to an extensive outgrowth of branching and anastomosing capillary-like tubes. This culture system provides a simple in vitro model for the study of angiogenesis.
Abstract Several hydrates can be synthesized from well-crystallized kaolinites; of importance to the present work are a 10-Å hydrate (called the QS-10 hydrate), an 8.6-Å hydrate, and two kinds of partially dehydrated mixed-layer hydrates. One kind is a series of unstable materials with d(001) varying continuously betw…

Potentiostatic, potentiodynamic, and immersion tests were conducted on a range of alloys used in paper-machine service. It was found that thiosulfate contamination of white water can cause pitting in AISI 304 and CA-15 stainless steels (SS), and, by comparison, salts such as NaCl, Na2SO3, and Al2(SO4)3 are much less c…

The measurement of volume charges within insulators has been attempted by various methods, including thermal, optical, mechanical, and electrical stimulation of the sample. A new method incorporating pulse electrical stimulation and pulsed acoustic detection is reported here. This technique is an extension of a previo…

PROLOGUE Computers influence our lives in more ways than we care to admit, and simulation or modeling is just one facet of a vast activity that will inevitably continue to grow even larger. Nowadays, computer simulation is used routinely in fields as diverse as econometrics and meteorology. The successes that have bee…
Abstract Cellulose fibers treated with different coupling agents based on trichloro‐ s ‐triazine have been evaluated in terms of their reinforcement effect on unsaturated polyesters. The treatment with coupling agents containing double bonds resulted in what we believe to be the formation of covalent bonds between fib…

Machine simulations and effective-medium theories are used to examine the influence of transverse (i.e., noncentral) forces on the elastic percolation transition in two dimensions. We consider models in which the transverse forces arise from (1) contact interactions between pairs of macroscopic particles and (2) bond-…
Thermodynamic calculations have been used to construct time temperature sensitization (TTS) diagrams for AISI 304 stainless steels (SS). The quantitative Stawstrom and Hillert model, which is based on chromium diffusion control of sensitization, was used to calculate the TTS diagrams. Electrochemical potentiokinetic r…

The coupled-cluster or exp S formalism, where the wave operator is expressed in exponential form, is treated for a general, multi-Configurational model space. It is shown that the cluster operator, S , is rigorously connected when the model space is complete or "quasi-complete" in the sense that it contains all config…

Breakdown of SF6is of commercial interest as a result of the large amounts of SF6-insulated switchgear installed world wide and is of technical interest as a result of the excellent dielectric strength of the gas caused by its high electronegativity. Previous studies in the area of positive surge breakdown area have c…
