Enterogastric reflux after various types of antiulcer gastric surgery: Quantitation by 99mTc-HIDA scintigraphy
(1991)In 28 controls and 142 patients subjected to a variety of antiulcer procedures, the enterogastric reflux (EGR) was quantitated by 99mTc-HIDA scintigraphy and expressed as the EGR index on 229 different occasions. The EGR ... -
Role of Prophylactic Antibiotics in Uncontaminated Neck Dissections
(1991)The use of perioperative prophylactic antibiotics in uncontaminated head and neck surgery remains controversial. We performed a retrospective analysis of 192 patients undergoing uncontaminated neck dissections from 1976 ... -
WALL-TO-BED HEAT-TRANSFER IN GAS SOLID FLUIDIZED-BEDS - PREDICTION OF HEAT-TRANSFER REGIMES
(1992)When studying heat transfer between a fluidized bed and immersed surfaces, three modes of heat transfer can occur, viz. conduction (particle convection), gas convection and radiation. A classical definition of the dominant ... -
A simulation of low-frequency electromagnetic phenomena in kinetic plasmas of three dimensions
(1993)An advanced kinetic simulation method has been developed and implemented in the HIDENEK code to study large space-scale, low-frequency electromagnetic phenomena occurring in inhomogeneous plasmas. The present method is ... -
Kinship relations and economic interdependence in family agriculture of the Greek plain
(1993)Small famliy holdings created by the agrarian reform since 1992 remain nowadays the major feature of the agrarian structure in the lowlands of central and northern Greece. Agriculturists are able to rent and cultivate ... -
LARGE-AMPLITUDE INTERFACIAL WAVES ON A LINEAR SHEAR-FLOW IN THE PRESENCE OF A CURRENT
(1993)The properties of two-dimensional steady periodic interfacial gravity waves between two fluids in relative motion and of constant vorticities and finite depths are investigated analytically and numerically. Particular ... -
NUMERICAL TREATMENT OF THE HEAT-TRANSFER FROM WALL TO FLUIDIZED-BED USING THE PARTICLE MODEL
(1993)The wall-to-fluidized bed conductive heat transfer process is studied in the case of glass particles, applying the ''particle-model''. A very accurate numerical method is developed within the implicit finite-difference ... -
A DERIVATION OF MOLECULAR VIBRATIONAL-ROTATIONAL HAMILTONIANS
(1993)The problem of collective molecular coordinates is examined within the Hamiltonian formalism by enlarging the number of degrees of freedom and transforming the model to a gauge theory (a theory where the solutions to the ... -
NEW FORMS OF GEOGRAPHICAL INEQUALITIES AND SPATIAL PROBLEMS IN GREECE
(1993)The dynamics of the restructuring of capital over the last fifteen years produced new territorial realities. One fundamental aspect of this evolution, in the case of Greece, is the relative decrease of interregional ... -
EXCIMER-LASER USED AS A MATERIALS CHARACTERIZATION TOOL - SULFIDE INCLUSION PRINTING IN STEEL
(1993)An application of the excimer laser in the area of material characterization making use of its ablative ability to perform surface sulphur printing is presented. It is shown that the differential ablative and surface melting ... -
KINETIC-STUDY OF PHOSPHORUS DESORPTION BY ALFISOLS AND ENTISOLS
(1993)The kinetics of phosphorus (P) desorption by six Greek soils, four Alfisols and two Entisols, have been studied. By the addition of several amounts of P fertilizers at different water/soil rations and different contact ... -
Phenomenological features of precipitation series in agricultural regions
(1993)A region in central Macedonia of northern Greece is used for the analysis, where the availability of water is mandatory for the agricultural activities of the region. Seven stations are employed with a 10-year record of ... -
OVERALL HEAT-TRANSFER COEFFICIENT OF A GREENHOUSE COVER
(1994)Theoretical considerations concerning the greenhouse energy behaviour during the night, allow us to propose an evaluation method of the overall heat transfer coefficient through the greenhouse cover material as a function ... -
THE SORPTION ISOTHERMS OF POTASSIUM
(1994)The one- and two-surface Langmuir, the Freundlich and the Temkin isotherms were fitted to potassium sorption data for Alfisol Haploxeralf at pH range of 4.0 to 8.0. Each was found to describe potassium sorption data with ... -
Subcapsular liver biloma complicating cholecystectomy after cholecystoduodenal fistula: CT findings. Case study
(1994)The computed tomographic (CT) appearance and differential diagnosis of a large subcapsular liver biloma is described. The lesion complicated an open operation for cholecystoduodenal fistula and its development distal to ... -
AN INVISCID INVESTIGATION OF THE INITIATION OF ROLL WAVES IN HORIZONTAL GAS-LIQUID FLOWS
(1994)A model with constant vorticity in the liquid phase has been applied to the study of interfacial waves between two inviscid fluids in relative motion, in order to take into account the shear induced into the liquid by the ... -
In vitro orbital volume measurement using computed tomography
(1994)A method for measuring orbital volume using CT with contiguous 3 mm axial sections is described. The accuracy of the method is 3.2% as demonstrated by comparing the CT volume measurements with those derived directly from ... -
PRESCRIPTION OF BRONCHODILATOR DRUGS BY PRIMARY HEALTH-CARE PHYSICIANS IN ASTHMA
(1994)With the purpose of estimating the use of bronchodilators in asthma management as prescribed by primary health physicians (PHCP) in Greece, 62 PHCP answered a questionnaire about the manner of choice of treatment, the ...
