A model for direct dragline casting in a dipping coal-seam
(SOUTH AFRICAN INST MINING METALLURGY, 2004)
This article introduces a computer model, which emphasizes panel design for draglines deployed in direct side-casting mode. The study covers flat and inclined coal-seam conditions with the dragline operating along the ...
Inverse spectral problems for Dirac operator with eigenvalue dependent boundary and jump conditions
(SPRINGER, 2011)
We deal with the Dirac operator with eigenvalue dependent boundary and jump conditions. Properties of eigenvalues, eigenfunctions and the resolvent operator are studied. Moreover, uniqueness theorems of the inverse problem ...
New observations on the 1939 Erzincan Earthquake surface rupture on the Kelkit Valley segment of the North Anatolian Fault Zone, Turkey
(PERGAMON-ELSEVIER SCIENCE LTD, 2013)
The 1939 Erzincan Earthquake (M=7.8), occurred on the North Anatolian Fault Zone (NAFZ), was one of the most active strike-slip faults in the world, and created a 360-km-long surface rupture. Traces of this surface rupture ...
Two gastrointestinal conditions with similar symptoms and endoscopic appearance: irritable bowel syndrome and microscopic colitis
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2015)
Background/aim: Irritable bowel syndrome (IBS) is a gastrointestinal condition characterized by chronic abdominal pain, discomfort, bloating, and alteration of bowel habits in the absence of any organic cause. This trial ...
Linear and nonlinear intersubband optical absorption coefficient and refractive index change in n-type delta-doped GaAs structure
(ELSEVIER SCIENCE BV, 2013)
In the effective mass approximation, we have theoretically investigated the subband structure of single Si delta-doped GaAs by solving the Schrodinger and Poisson equations self-consistently. Both the linear and nonlinear ...
Effect of Laurus nobilis L. Essential Oil and its Main Components on alpha-glucosidase and Reactive Oxygen Species Scavenging Activity
(SHAHEED BEHESHTI UNIV, SCH PHARMACY, 2013)
The present study was designed to determine the effects of the essential oil of Laurus nobilis L. (Lauraceae) and its three main components on a-glucosidase and reactive oxygen species scavenging activity. The chemical ...
Impurity-related optical response in cylindrical quantum dots with a delta-doped axial potential under an intense laser field
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)
A theoretical study of the effects of a nonresonant intense laser field on the absorption coefficients and refractive index changes for a two-level system associated with transitions from the 1S -like impurity state to the ...
Combined biological removal of nitrate and pesticides using wheat straw as substrates
(ELSEVIER SCI LTD, 2005)
Nitrate and the selected pesticides, trifluralin, fenitrothion and endosulfan (alpha + beta) removal was studied in an up flow biological denitrification reactor packed with wheat straw as carbon source and support particles ...
Long-term Efficacy and Safety of Lamivudine, Entecavir, and Tenofovir for Treatment of Hepatitis B Virus-Related Cirrhosis
(ELSEVIER SCIENCE INC, 2013)
BACKGROUND & AIMS: Data are limited on the efficacy and safety of tenofovir and entecavir when given for more than 1 year to patients with hepatitis B-related cirrhosis. We investigated the long-term safety and efficacy ...
Normative size evaluation of internal auditory canal with magnetic resonance imaging: review of 3786 patients
(VIA MEDICA, 2012)
Background: A narrow internal auditory canal (IAC) is significantly associated with congenital sensorineural hearing loss. It would therefore seem likely that any patient with an IAC measured radiographically to be under ...
