Superficial deep-water sediments of the Eastern Marmara Basin
Superficial sediments (top ∼ Im) of the Eastern Mediterranean Basin, Sea of Marmara, Turkey accumulated rapidly (0.087 ± 0.012 g/cm2 · y) by hemipelagic sedimentation with only limited amounts of gravity flow or bottom ...
A Monte Carlo study of the BNNNI model
(IOP Publishing, 1989)
The biaxially next-nearest-neighbour Ising (BNNNI) model is studied using the Monte Carlo procedure. The structure factor is used to identify the possible phases of the system. At intermediate temperatures, evidence for ...
Sorption of barium on kaolinite, montmorillonite and chlorite
(Royal Society of Chemistry, 1989)
The sorption characteristics of the Ba2+ ion on kaolinite, montmorillonite and chloritetype clays were studied using the batch method. Barium-133 was used as a tracer. The Ba2+ ion concentrations ranged from 10-8 to 10-5 ...
Quantum mechanical simulation of charge transport in very small semiconductor structures
A quantum mechanical simulation method of charge transport in very small semiconductor devices, based on the numerical solution of the time-dependent Schrödinger equation (coupled self-consistently to the Poisson equation ...
Generalization of the Von Staudt-Clausen theorem
The localization LS(x) of log(1 + x) at a set of primes S is defined by taking those powers of x in the logarithmic series for log(1 + x) which lie in the span of S. The functional inverse LS-1(x) of LS(x) also localizes ...
Efficiency calibration and summation effects in gamma-ray spectrometry
(Kluwer Academic Publishers, 1988)
Precise, absolute γ-ray efficiences (∈γ) and total efficiences (∈T), have been measured at various distances from the detector, using a set of standards. The observed linear variation of ∈γ and ∈T as well as ∈γ/∈T with Eγ ...
Sorption of cesium and strontium on montmorillonite and kaolinite
(De Gruyter Oldenbourg, 1988)
Sorption characteristics of Cs+ and Sr++on montmorillonite and kaolinite type clays and soil fractions from various regions of Turkey were studied using the batch method. 137Cs and 90Sr were used as tracers. Concentrations ...
An isomorphism theorem for Dragilev spaces
Necessary and sufficient conditions for an Ly(a, l)-space to be isomorphic to some Lg(b, m)-space have been found.
Critical relaxation of the two-dimensional three-state Potts model with conserved dynamics
(Institute of Physics (Great Britain), 1988)
The dynamical critical exponent z is obtained using the finite-size scaling method for the two-dimensional three-state Potts model with conserved dynamics. It is observed that there is a change in the dynamical behaviour ...
Sedimentation rates in the central lake constance determined with210Pb and137Cs
Sediment cores from central Lake Constance were dated with210Pb and137Cs. A sedimentation rate of (0.11±0.02) g·cm-2·y-1 was determined with the210Pb method.137Cs measurements revealed sedimentation rates of (0.11±0.01) ...
