We investigate the relaxation rate and mobility of a two-dimensional electron gas (2DEG) confined in MgZnO/ZnO heterostructures (HSs) for temperatures , taking into account exchange and correlation effects. We use the variational-subband-wave-function mod... see more

We investigate correlation and magnetic field effects on the mobility and resistivity of a quasi-two-dimensional electron gas in an InP/In1-x_{1 - x}Gax_{x}As/InP quantum well at arbitrary temperatures. We study the dependence of the mobility and resis... see more

The level structure for negative ions (anions) of some atoms with half-filled p shell have been investigated using the multiconfiguration Hartree-Fock method with Breit-Pauli relativistic effects (MCHF+BP method). Thus, we have performed a systematic calc... see more

This paper examines the relation between serial correlation and volatility of the Ibovespa index returns and extends the empirical evidence of the LeBaron effect for higher orders of serial correlation. We employ an exponential general autoregressive cond... see more

Neutron diffraction measurement of powder a-Fe sample at 295 K was carried out at the high resolution powder diffractometer installed at Japan Proton Accelerator Research Complex (J-PARC). Crystal parameters were determined from Rietveld analysis. Th... see more

In education, the curriculum is the most important needs. It becomes a practice guidance for teachers. Moreover, the curriculum was made to be implemented, so that the most important measurement of good curriculum is the practical aspect. This research is... see more

Methicillin-resistant Staphylococcus aureus (MRSA) is a pathogenic bacterium that has been resistant to various types of antibiotics, so it is not easy to be treated with antibiotics and needs other solutions. Javanese citronella oil distilled from the Cy... see more

This article aims to describe and describe the relationship between effective sentence mastery and student motivation to write explanatory text skills. The results of data processing using multiple regression to the explanatory text writing variable (Y) r... see more

The purpose of this work was to evaluate the effectiveness of some modern methods of preservation of the hole, aimed at preserving the tissues of the alveolar process of the jaws immediately after tooth extraction. Clinical studies were conducted in 69 pa... see more
