Laboratory experiments on the investigation of the effects of sulphuric acid on the deterioration of carbonate stones and surface corrosion
(KLUWER ACADEMIC PUBL, 1999)
In this study, the effect of sulphuric acid, the major constituent of acid rain, on carbonate stones has been investigated. For this purpose, samples from historical buildings of Sivas city have been collected. The ...
Supression of cardiac parasympathetic functions in patients with right hemispheric stroke
(BLACKWELL SCIENCE LTD, 1999)
Objectives: The aim of this study was to investigate the relationship between sympathetic and cardiac parasympathetic function and the side of the lesion in stroke patients. Methods: Thirty-two patients with stroke and 29 ...
Right-sided hiatal hernia of the oesophagus
(SCANDINAVIAN UNIVERSITY PRESS, 1999)
At chest radiography performed for recurrent pneumonia in a 3-month-old boy, an air-fluid level in the right cardiophrenic angle was found and initially perceived as a lung abscess. Upper gastrointestinal tract radiographs, ...
Electric field dependence of the excitonic properties in graded double quantum wells
(IOP PUBLISHING LTD, 1999)
A quasi-bound state approximation is used to obtain the electric field dependence of the eigenvalues, eigenfunctions, electron-hole overlap integrals and excitonic binding energies for coupled, graded double quantum wells ...

(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 ...
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 ...
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 ...
A review on the radiation synthesis of copolymeric hydrogels for adsorption and separation purposes
(PERGAMON-ELSEVIER SCIENCE LTD, 1999)
Recent theoretical and experimental work on the radiation synthesis, characterization and the use of hydrogels containing diprotic acid moieties have been reviewed. It is shown that upon incorporating vinyl monomers carrying ...
