the liquefaction resistance of soil can be evaluated using laboratory tests such as cyclic simple shear, cyclic triaxial, cyclic torsional shear as well as field methods like standard penetration test (spt), cone penetration test (cpt) and shear wave velocity (vs). in this regard, this study attempts to compare the results of the spt based on the simplified procedure proposed by seed and idriss...

In this paper, we study cyclic codes over the Galois ring GR(p, s). The main result is the characterization and enumeration of Hermitian self-dual cyclic codes of length pa over GR(p, s). Combining with some known results and the standard Discrete Fourier Transform decomposition, we arrive at the characterization and enumeration of Euclidean self-dual cyclic codes of any length over GR(p, s). S...

Fig. 3 shows the total times in milliseconds for a cyclic(192) to cyclic(8) redistribution on 32 processors for increasing data sizes. This redistribution corresponds to the cyclic(Y t) to cyclic(t) case with Y = 2...

Kuriki and Fuji-Hara (1994) introduced an (r, 2)-design with mutually balanced nested subdesigns ((r, 2)-design with MBN), which is equivalent to a balanced array of strength 2 with s symbols, and gave some constructions of such (r, 2)-designs. In this paper, we consider cyclic orthogonal and balanced arrays, and we give a cyclic version of the results obtained by them. Furthermore, we give a c...

The A2BO4 spinel oxides are distinguished by having either a normal (N) or an inverse (I) distribution of the A, B cations on their sublattices. A point-ion electrostatic model parametrized by the oxygen displacement parameter u and by the relative cation valencies Z{A} vs Z{B} provides a simple rule for the structural preference for N or I: if Z{A}>Z{B} the structure is normal for u>0.2592 and...

Alpha-alkyl substituted fluorenylidene allene oxides were generated photochemically from appropriately substituted fluorenol derivatives in 2,2,2-trifluoroethanol (TFE) in order to assess the affect of steric bulk on the absolute reactivity of the allene oxides. The absolute reactivities of the allene oxides were measured using nanosecond laser flash photolysis, and were found to change little ...

We report new step-by-step reduction methods by alternating two different reducing reagents with the order of hydrazine with NH(3) (NH)/HI in acetic acid (HI) and the reverse order (HI/NH) to understand nitrogen incorporation and removal or reduction for providing highly qualified reduced graphene oxides (rGOs).

The general method for the tandem phosphination-decarboxylation-oxidation of alkynyl acids under aerobic conditions has been developed. In the presence of CuSO4·5H2O and TBHP, the reactions provide a novel access to β-ketophosphine oxides in good to excellent yields. This transformation allows the direct formation of a P-C bond and the construction of a keto group in one reaction.

1. In the presence of Ca2+, a 5.3-S 3':5'-cyclic nucleotide phosphodiesterase (EC 3.1.4.17) from bovine ventricle was isolated and purified by (NH4)2SO4 precipitation and DEAE-cellulose and Affi-Gel Blue chromatography. The enzyme activity was enriched 800-fold by these procedures. 2. Sucrose-density gradient centrifugation, gel filtration and non-denaturing polyacrylamide-gel electrophoresis r...
