Characterization and synthesis of some alternating terpolymers of maleic anhydride
(MATRICE TECHNOLOGY LIMITED, 2004)
In this study, MA-S-MMA, MA-S-VA and MA-S-AP terpolymers have been synthesized in methyl ethyl ketone from methyl methacrylate (MMA), vinyl acetate (VA), allyl propionate (AP), styrene (S), and maleic anhydride (MA) monomers ...
Adaptive heuristic temperature control of a batch polymerisation reactor
(ELSEVIER SCIENCE SA, 2004)
The purpose of this research is to improve and apply the temperature control of a free radical solution polymerisation of styrene and to examine its performance on the basis of adaptive heuristic criticism (AHC) control. ...
Investigation of the mechanism of nicotine induced relaxation in rabbit corpus cavernosum in vitro
(SPRINGER, 2004)
In order to determine whether nicotine acts on corporal smooth muscle, the mechanism of its effect on strips of rabbit corpus cavernosum was studied in vitro. Rabbit corpus cavernosum muscle strips were mounted in an organ ...
An unusual cause of adnexal mass: fallopian tube schwannoma
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004)
Background. Schwannoma is a well-defined, usually benign tumor arising from the Schwann cells in the nerve sheath. It can present in any location as a solitary mass; however, it is rarely found in the pelvis. Case. We ...
Psychosocial approaches in outpatients with schizophrenia
(AMER PSYCHOLOGICAL ASSOC, 2004)
The objective of this study was to determine how psychosocial approaches to people with schizophrenia, in addition to treatment with psychotropic drugs, affect the course of the illness and family interactions. The project ...
A functioning-desensitization paraganglioma which caused hemodynamic instability during tumoral resection: Report of a case
(SPRINGER, 2004)
Paragangliomas are uncommon tumors arising from the neuroendocrine elements of the paraganglia. Their successful management is associated with many problems. We herein present the findings of a 22-year-old man in whom a ...
Intersubband optical absorption in quantum wells under applied electric and intense laser fields
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2004)
Within the framework of the effective mass approximation, we have theoretically investigated the linear intersubband optical absorption in a quantum well under external electric and intense laser field. Results obtained ...
Effects of crossed electric and magnetic fields on shallow donor impurity binding energy in a parabolic quantum well
(IOP PUBLISHING LTD, 2004)
We have calculated variationally the ground state binding energy of a hydrogenic donor impurity in a parabolic quantum well in the presence of crossed electric and magnetic fields. These homogeneous crossed fields are such ...
Shallow donor impurities in different shaped double quantum wells under the electric field
(WILEY-V C H VERLAG GMBH, 2004)
The binding energy of the donor impurity in double triangle quantum well (DTQW), double graded (DGQW) and double square (DSQW) GaAs-(Ga,Al)As quantum wells under the electric field is calculated by using a variational ...
Increased frequency of familial Mediterranean fever in central Anatolia, Turkey
(CLINICAL & EXPER RHEUMATOLOGY, 2004)
Objective. It has been observed that familial Mediterranean fever is more prevalent among people coming from central Anatolia in Turkey. To test this observation the frequency of FMF was investigated by afield survey in ...
