In the wake of damaging earthquakes in both the United States and Japan over the past year, the performance of structures, in addition to traditional life-safety concerns, has become an important issue for designers and owners. Many possible approaches to enhancing the seismic performance of structures have been propo…
We propose a systematic method of analyzing pseudopotential transferability based on linear-response properties of the free atom, including self-consistent chemical hardness and polarizability. Our calculation of hardness extends the approach of Teter\cite{teter} not only by including self-consistency, but also by gen…
Part 1 Alloy characteristics: the nature of stainless steels and nickel-rich alloys corrosion effects of fabrication/welding. Part 2 Aqueous environments: aqueous corrosion fossil fuel combustion power and heat. Part 3 Oil and gas operations: oilfield applications of stainless steel petroleum refining. Part 4 Process…
We present molecular dynamics simulation measurements of the viscosities of the Gay-Berne phenomenological model of liquid crystals in the nematic and isotropic phases. The temperature dependence of the rotational and shear viscosities, including the nonmonotonic behavior of one shear viscosity are in good agreement w…
Food macromolecules play a crucial role in the formulation of a wide range of food products such as beverages, bread, cheese, dressings, desserts, ice-cream, and spreads. This book presents the very latest research in the area and is unique in covering both proteins and polysaccharides in the same volume. Specifically…

We calculate the Raman spectrum of the two-dimensional (2D) spin-1/2 Heisenberg antiferromagnet by exact diagonalization and quantum Monte Carlo techniques on clusters of up to 144 sites and, on a 16-site cluster, by considering the phonon-magnon interaction which leads to random fluctuations of the exchange integral.…
Abstract A series of new, fluorinated poly(imide–amide–sulfone)s has been synthesized by solution polycondensation of aromatic diamines containing sulfone groups with diacid chlorides incorporating both imide and hexafluoroisopropylidene units. These polymers are soluble in polar amidic solvents, and their solutions c…
Porphyrin arrays may act as light-harvesting devices which mimic the photosynthetic capture of light. Until now the construction of a variety of arrays has been restricted by the lack of suitable methodology for porphyrin synthesis. A fully conjugated, aldehyde-appended porphyrin building block has been made and its p…
Abstract A semicrystalline polyamide polymer was processed using a new technique known as mechanical alloying. The material processed by this technique was first introduced into a high‐energy ball mill and ground over long periods of time, resulting in the production of extremely fine powders. These powders were subse…
A value of 2.71 μB for the effective magnetic moment between 100 and 300 K is determined for 1. This magnetic moment supports the assumption of a triplet ground state for 1. The bis(nitroxyl) diradical, which melts only at 180 °C with decomposition, could be characterized by X-ray crystallography. It has a distinctly…
A ferromagnetic exchange interaction that is not influenced by the distortion of the cubane framework of 1 (see picture; only the O atoms of the EtOH and dbm− ligands are shown) and is mediated by the end-on-coordinated μ3-azide bridges has been detected for the first time. Although the unusual [M4(η1-μ3-N3)4] core is…
Eighteen different collagen types have now been identified, at least five of which are found in the extracellular matrix of the heart. The interstitial collagens, types I and III are the most abundant components. Due to their tensile strength and arrangement in a network, surrounding and inter-connecting myocytes and…
Abstract Photosynthesis is one of the fascinating fields of current interdisciplinary research. It seems miraculous that nature, in the process of evolution, has managed to bring about the process of photosynthesis. The first step involves a charge separation at the reaction centers, which proceeds with 100% quantum y…
Abstract Single crystals of the hitherto unknown compound CuSbMo 2 O 8 were prepared by recrystallization from melts in closed copper tubes and investigated by X-ray diffractometer technique. CuSbMo 2 O 8 crystallizes in a new structure type with monoclinic symmetry, space group C 6 2h - I12/a1, a = 5.554(2), b = 4.91…
Abstract Dicarboxy‐terminated poly(2,6‐dimethyl‐1,4‐phenylene oxide) (PPO) macromonomers were prepared and subjected to the preparation of tailor‐made aromatic thermotropic liquid‐crystalline (LC) polyester‐ graft ‐PPO copolymers. The macromonomers were obtained by hydrolysis of dimethyl carboxylate‐terminated PPO mac…
Abstract Durch Tempern der binären Oxide CsO 0,52 , NaO 0,45 , LiO 0,5 und GeO 2 im mol. Verhältnis 1,24:1,4:6,7:3,9 (Ni‐Bömbchen; 600°C/89 bzw. 65 d) wurden erstmals Einkristalle von CsNa 3 Li 8 {Li[GeO 4 ]} 4 in Form von schwachgelblichen Prismen sowie blaßgelbem Pulver erhalten: Raumgruppe I 4/ m (I.

The purpose of this paper is to present an easy method for analyzing the operating characteristics of a separate-type transformer connected to an external circuit including elements such as batteries, resistances, and diodes. This method, a combination of two- and three-dimensional finite element methods, has been app…
An extensive database of aerosol experiments exists and has been used for checking aerosol transport codes. Data for fission product vapor transport are harder to find. Some qualitative data are available, but the Falcon thermal gradient tube tests carried out at AEA Technology’s laboratories in Winfrith, England, mar…
The effect of in the sub‐parts per million range on the atmospheric corrosion of zinc has been investigated in the laboratory. Each sample was exposed individually to air with careful control of pollutant concentration, relative humidity, and flow conditions. Monitoring of concentration at the outlet of the corrosion…
