Ammonium oxidation via nitrite accumulation under limited oxygen concentration in sequencing batch reactors
(ELSEVIER SCI LTD, 2009)
In this study, the effects of sludge retention time (SRT) on NH(4)-N oxidation and NO(x)-N accumulation in the nitritation reactors were studied. The gradually decrease of SRT also caused long reaction time to achieve 99% ...
Analysis of current-voltage-temperature characteristics and T-0 anomaly in Cr/n-GaAs Schottky diodes fabricated by magnetron sputtering technique
(ELSEVIER SCIENCE BV, 2009)
We have fabricated two groups of Cr/n-GaAs Schottky diodes (SDs) by magnetron sputtering technique to determine whether To anomaly varies in similarly fabricated SDs or not. Firstly, the first group diodes were inserted ...
Controlled Hypotension With Desflurane Combined With Esmolol or Dexmedetomidine During Tympanoplasty in Adults: A Double-Blind, Randomized, Controlled Trial
(ELSEVIER SCIENCE INC, 2009)
BACKGROUND: Controlled hypotension is a technique that is used to limit intraoperative blood loss to provide the best possible Surgical field during surgery. OBJECTIVE: The aim of this double-blind, randomized, controlled ...
4-(Methylamino)benzoic acid
(WILEY-BLACKWELL, 2009)
The asymmetric unit of the title compound, C8H9NO2, contains three crystallographically independent molecules, which are essentially planar, the carboxyl O atoms deviating by 0.091 (3), 0.101 (2) and 0.164 (3) angstrom ...
Fibrolipoma as a Rare Lesion of Oral Cavity: Magnetic Resonance Imaging Findings: Original Image
(ORTADOGU AD PRES & PUBL CO, 2009)
Fibrolipoma is a benign tumor variant of lipoma. Fibrolipomas of the oral cavity are rare. They are more frequent in males than in females, built mostly of fibrous connective tissue. Magnetic resonance imaging (MRI) findings ...
Modification of Diet in Renal Disease equation in the risk stratification of contrast induced acute kidney injury in hospital inpatients
(SOC ESPANOLA NEFROLOGIA DR RAFAEL MATESANZ, 2009)
Background: Several organizations recommend using estimated glomerular filtration rate (eGFR) in kidney function monitoring, preferably calculated with Modification of Diet in Renal Disease (MDRD) formula. The role of this ...
Mechanical and microstructural properties of low-carbon steel-plate-reinforced gray cast iron
(ELSEVIER SCIENCE SA, 2009)
In the present experimental study, strengthening of gray cast iron by reinforcing with steel plates was investigated in the as-cast and normalized conditions. Normalizing heat treatments were applied to the specimens at ...
Nursing students' level of autonomy: A study from Turkey
(CHURCHILL LIVINGSTONE, 2009)
Nursing curriculum programs developed to train future professional nurses, methods of teaching and learning and practice can either prepare or be an obstacle to the students' thinking and acting like independent professionals. ...
Microleakage in Resin Composite Restorations After Antimicrobial Pre-treatments: Effect of KTP Laser, Chlorhexidine Gluconate and Clearfil Protect Bond
(OPERATIVE DENTISTRY INC, 2009)
The current study evaluated the influence of KTP (Potassium-Titanyl-Phosphate) laser irradiation, 2% chlorhexidine gluconate and Clearfil Protect Bond on the microleakage of Class V composite restorations. Thirty human ...
Dronedarone: A Promising Alternative for the Management of Atrial Fibrillation
(SPRINGER, 2009)
Atrial fibrillation (AF) is the most frequently encountered chronic arrhythmia associated with significant morbidity. It is generally encountered in the elderly, and will presumably become more prevalent in the future due ...
