THERMAL-DEGRADATION OF BLENDS OF PVC WITH BISPHENOL-A POLYCARBONATE
(ELSEVIER SCI LTD, 1993)
The thermal degradation of blends of PVC with bisphenol A polycarbonate has been studied by thermogravimetry and thermal volatilisation analysis. In the TG experiments, both programmed heating and isothermal heating (at ...
THERMAL-DEGRADATION OF BLENDS OF PVC WITH POLY(ETHYLENE ADIPATE)
(ELSEVIER SCI LTD, 1993)
The thermal degradation of PVC-PEAD blends has been studied over the whole composition range, using thermal volatilisation analysis and thermogravimetry. In the TVA studies, degradation products have been separated and ...
Investigation of acid sites on V2O5/TiO2(A) catalysts by FTIR with adsorption of pyridine
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1996)
The V2O5/TiO2(A) catalysts were prepared by the grafting and their Bronsted and Lewis acid sites were investigated with pyridine adsorption by using FTIR Spectroscopy. The results obtained showed that monolayer or less ...
The effects of long-term oral administration of L-arginine on the erectile response of rabbits with alloxan-induced diabetes
(BLACKWELL SCIENCE LTD, 1999)
Objective To investigate the effects of the long-term oral administration of L-arginine on the impaired neurogenic and endothelium-dependent relaxation responses of corpus cavernosum smooth muscle from alloxan-induced ...
Relapsing significant bacteriuria: Effect on urinary tract infection in patients with spinal cord injury
(W B SAUNDERS CO, 1997)
Objective: To evaluate whether there is a relation between relapsing significant asymptomatic bacteriuria (ASB) and symptomatic urinary tract infection (UTI), and to determine the frequency rate of UTI in patients with ...
Eggplant tissue homogenate-based bioselective membrane electrode for determination of catechol
(NATL INST SCIENCE COMMUNICATION, 1999)
A novel eggplant tissue homogenate-based membrane electrode with high selective response to catechol (5x10(-6)-2.5x10(-5) M concentration) has been constructed by immobilizing tissue of eggplant (Solanum melangena L.) at ...
DETERMINATION OF CEFTRIAXONE IN AQUEOUS-HUMOR AND SERUM SAMPLES BY DIFFERENTIAL-PULSE ADSORPTIVE STRIPPING VOLTAMMETRY
(ROYAL SOC CHEMISTRY, 1994)
Differential-pulse adsorptive stripping voltammetry was used to determine ceftriaxone in serum and aqueous humour samples. The method involved extraction of the ceftriaxone from serum samples with an Amberlite XAD-2 column ...
Hamuli in the Hymenoptera (Insecta) and their phylogenetic implications
(TAYLOR & FRANCIS LTD, 1997)
Hamuli are hook-like setae on the anterior margin of the hind wing which interlock with the recurved posterior edge of the fore wing in the Hymenoptera during flight, making them functionally two winged. The possession of ...
The effect of different doses of calcitonin on bone mineral density and fracture risk in postmenopausal osteoporosis
(MEDICOM INTERNATIONAL, 1998)
A total of 107 patients were included in the study to determine the effects of different doses of intranasal calcitonin on bone mineral density and fracture risk in postmenopausal osteoporosis. Patients were randomly divided ...
Grain size and clay mineralogy of Late Quaternary sediments on a tectonically active shelf, the southern Sea of Marmara: clues to hydrographic, tectonic and climatic evolution
(JOHN WILEY & SONS LTD, 1999)
The clay mineral content and grain size composition of sediments obtained from 29 cores (up to 350 cm in length) on the southern Marmara shelves have been analysed in order to determine the effects of climatic, neotectonic ...
