THE GEOELECTRICAL - RHEOELECTRICAL METHOD FOR THE MANAGEMENT OF UNDERGROUND WATER BY DANIEL TOACĂ, IOSIF BARTHA, RODICA MARIA NEAGU, NICOLAE MARCOIE Abstract. This paper proposes a combination of two electrical methods: the geoelectrical tomography and the rheoelectrical investigation of underground water sources. Both methods are using the analogy in some situations with the basic equations of electrodynamics and hydrodynamics. This is a new method that we propose for a nondestructive investigation of caption front for an utilization of underground water in several proposes. Key words: geoelectrical tomography, rheoelectrical investigation, water sources. AN ANALYSIS OF A HIGH GRADIENT MAGNETIC SEPARATOR FOR EXTRACORPOREAL BLOOD PURIFICATION BY VASILE BĂDESCU, LAURA-ELENA UDREA, OVIDIU ROTARIU, RODICA BĂDESCU, GABRIELA APREOTESEI Abstract. We analyze and prove the feasibility of a model of HGMS magnetic separator for extracorporeal blood purification of excess chemo- or radio-therapeutic drugs from cancer patients or for eliminating toxin-bounded magnetic spheres from the bloodstream. The separator consists of an array of capillary tubing and magnetizable wires adjacent in the exterior of these. The wires are magnetized perpendicular to their axes by a magnetic field generated by two parallel magnets. The capture efficiency of a single separation cell is investigated using a mathematical model. Key words: magnetic separator, blood detoxification, magnetic microsphe-res.
SOME FEATURES OF ELECTRIC AND MAGNETIC SEPARATION OF NANOSPHERES FROM A SIMULATED BIOLOGICAL FLUID BY LAURA-ELENA UDREA, VASILE BĂDESCU, OVIDIU ROTARIU , RODICA BĂDESCU, GABRIELA APREOTESEI Abstract. We are working in developing a tool for rapid removal of biohazards from human blood. For this we realized a mini magnetic separator capable of separating magnetic nano/micro-carriers from arterial blood flow in an ex vivo unit. Here we evaluate the performance of our separator. Pure water and ethylene glycol–water solutions with a viscosity of 3.0 cP and 4.0 cP (v:v = 39:61 and v:v = 49:51, respectively) were used as the fluids. The results demonstrated the feasibility of achieving high capture efficiency for blood in the prototype magnetic separator for biomedical applications. Key words: magnetic separator, blood detoxification, extracorporeal unit, in vitro tests. SOME FEATURES OF ELECTRIC AND MAGNETIC FIELDS EMITTED BY CRT COMPUTER MONITORS BY CRISTIAN GOICEANU, RĂZVAN DĂNULESCU, FLORIN MIHAI TUFESCU Abstract. The aim of our study is to determine electric and magnetic field levels as well as spectral composition of emissions in the proximity of some CRT computer monitors. Field measurement and analyze were carried at distances up to 0.7 m from computer monitors. Broad-band level measurements, as well as spectral analysis covered the low frequency domain up to 32 kHz. Measured levels of electric and magnetic field are low comparing to the limits set by human exposure standards. Spectral analysis showed interesting differences in present components and weight of various frequencies between different models of monitor. Key words: CRT monitors, electric and magnetic fields, spectral analysis. OPTICAL CENTRED SYSTEM OF THE HUMAN EYE BY MIHAELA MIRON, MONA-LISA CAZACU Abstract. In the hypothesis that human eye is an optical centred system, the cardinal elements of the human eye were calculated and used in order to obtain the image of an object in Gaussian approximation. Key words: eye cardinal elements.
