Effects of ionic environments on bovine serum albumin fouling in a cross-flow ultrafiltration system
(WILEY-V C H VERLAG GMBH, 2007)
The influence of electrostatic interactions on membrane fouling during the separation of bovine serum albumin (BSA) from solution was studied in a cross-flow ultratiltration system. Experiments were carried out at different ...
ON A THEOREM OF POSNER FOR 3-PRIME NEAR-RINGS WITH (alpha,tau)-DERIVATION
(HACETTEPE UNIV, FAC SCI, 2007)
The analog of Posner's theorem on the composition of two derivations in prime rings is proved for 3-prime near-rings with d(1) a (alpha,tau)-derivation and d(2) a derivation.
Acute coronary syndrome: Short-term effects of early intravenous metoprolol on maximum P wave duration and P wave dispersion
(HEALTH COMMUNICATIONS INC, 2007)
In patients with acute coronary syndrome (ACS), the presence of atrial fibrillation (AF) results in worse inpatient outcomes than in those without AF Two electrocardiographic markers, maximum P wave duration (P-maximum) ...
Scavenging effect and antispasmodic activity of the essential oil of Cyclotrichium niveum
(ELSEVIER SCIENCE BV, 2007)
The radical scavenging and the spasmolitic activity of Cyclotrichium niveum essential oil were evaluated in vitro. It showed an IC50 of 1750 mu g/ml on DPPH method and dose dependently (0.1, 0.5 and 1 mg/ml) inhibits the ...
The effect of swelling clays on a water transport canal between Kokluce HPP and Erbaa HPP (Turkey)
(SPRINGER HEIDELBERG, 2007)
Geological mapping has confirmed the presence of swelling clays in the area of the proposed water transport canal between Korkluce and Erbaa, Turkey. A swelling pressure distribution map was prepared for this part of the ...

Myxoma is the most frequently encountered primary tumour of the heart, comprising more than 50% of all benign cardiac tumours. The case presented here was diagnosed as having dextrocardia with situs inversus and concomitant ...
Characteristics of Fe-exchanged natural zeolites for the decomposition of N2O and its selective. catalytic reduction with NH3
(ELSEVIER SCIENCE BV, 2007)
Natural zeolites obtained from various regions of Turkey and their iron-exchanged forms were characterised by XRD, BET, H-2-TPR and NH3-TPD methods. Transient experiments with N2O showed that the iron introduced into natural ...
