Full textOne of the major problems arising from the use of implants and medical devices and impeding their long-term use is the emergence of nosocomial septic incidents related to infections caused by Coagulase negative staphylococci, most notably by S. epidermidis. The extensive use of antibiotics has resulted in multi-resistant bacterial strains of normal flora, making the need for developing antibacterial biomaterials of great importance. For this purpose it is necessary to study and understand the mechanism of bacterial adhesion to the surface of biomaterials. In this direction, we investigated the influence of the physicochemical interactions between bacteria and materials, the shear rate and their relative contribution on the ability of bacteria to adhere to the biomaterial surface and to activate the ica genes, which are responsible for the production of extracellular polymeric (slime), and in particular for the production of polysaccharide intercellular adhesin (PIA), that mediates cell-cell interactions. For this study, the surface of existing biomaterials was modified by plasma methods, self-assembled monolayers were prepared on glass, and the materials were physicochemicaly characterized. The applicability of the colloidal theories, such as the thermodynamic, the DLVO and the extended DLVO, for the prediction of bacterial adhesion was examined as well. The results showed that the increase in material surface energy and its polar component reduced bacterial adhesion, whereas adhesion was not significantly influenced by the non-polar character of the material surface. The thermodynamic theory explained satisfactorily the results for high ionic strength solutions, while DLVO for solutions with low ionic strength. The extended DLVO theory explained well the effects of both the solution and material surface properties to bacterial adhesion. The increase in shear rate reduced the number of adherent bacteria in a manner that depended on the bacteria-material physicochemical interactions, but not in the way that the above theories predicted. Therefore, bacterial adhesion considered as the result of a combination of the physicochemical and hydrodynamic interactions, and the formation of macromolecular bonds. The investigation of ica genes expression showed that the expression enhanced by the decrease in the material surface energy the increase in shear rate.

Full textFlexible polymer chains end-tethered to a surface in good solvent tend to extend away from the surface due to excluded volume interactions. At sufficiently high grafting densities the chains become elongated normal to the surface, this extension being opposed by an elastic restoring force of entropic origin to form a layer of stretched chains referred to as a “polymer brush”. These systems have been studied extensively in recent years by numerous experimental techniques and theoretical methods. In the present investigation we have studied asymmetric star-shaped polymers whereby the different arms are either non-adsorbing PS chains or short PB chains terminating in a zwitterionic end-group known to adsorb strongly on surfaces such as mica or quartz. In this manner, it is possible on the one hand to form brushes with a single PS chain, but multiple zwitterionic stickers, and on the other to study the reverse case of multiple non-adsorbing arms attached to a surface via a single zwitterions. We have used the surface force balance technique to determine the interaction between such brush-layers formed on mica and neutron scattering to determine the absorbed amount and interanchor distance. Interactions between polymer brushes formed by highly asymmetric star-like polymers with a long PS arm and one, two or three short PB arms each terminating in a zwitterionic end-group were studied in order to explore the effect of the sticking energy on the brush structure. Polystyrene stars with two and three tails bearing a single end group were also studied to investigate how the height of the adsorbed layer and the grafting density are affected. Our measurements show no significant differences between PS with 1, 2 and 3 end groups. This may be due to kinetic reasons since additional polymer chains are hindered from attaching to a brush-bearing surface. The behavior of two PS chains with one end-group ((PS)2-PB-X) seems not to differ appreciably from that of PS-PB-X copolymer. On the other hand three PS chains with one end-group ((PS)3-PB-X) appeared to form layers with smaller brush height and greater interanchoring distance, relative to PS-PB-X layers. We can attribute this to the extra stretching that the three-chain architecture imposes on the adsorbed brush. In the present investigation we have also studied weak polyelectrolytes. Polyelectrolytes (charged polymer chains) remain among the least understood materials despite their importance in biology (proteins, DNA) and materials science. Their behavior and characteristics are not yet fully understood because of complicated correlations due to their charged nature that gives rise to long-range interactions. The counterplay of their properties as polymers and electrolytes with counterions around polyelectrolyte chains imposes additional difficulties on explaining their behavior. The association of counterions around polyelectrolytes and the pH of the solution are two parameters than can affect the properties of such systems. Especially weak polyelectrolytes (like poly-acrylic acid) are even sensitive to pH changes because of the alterable degree of dissociation. We measured forces between two charged polymer layers of Poly (isoprene-acrylic acid) diblock copolymers adsorbed on mica surfaces. Poly (isoprene-acrylic acid) diblock copolymers can be adsorbed from one end (poly-isoprene) which is sorter than the poly-(acrylic acid) part. The properties of the polymer layer at various salt concentrations and different pH of the solutions were measured by Surface Forces Apparatus. Information about the height of the polymer layer, and the adsorbed amount were extrapolated. The extracted results were compared with theoretical predictions showing well fit.

Full textΤhe object of this doctoral thesis is the study, in depth analysis and modelling of the electromagnetic interaction between the human body and the antennas used in the handsets of modern wireless telecommunication systems. The aim is twofold. On one hand is the estimation of the antenna efficiency reduction that is caused by the presence of the user’s body in small distance and on the other hand is the study and precise determination of the electromagnetic radiation absorbed by the human body (especially the human head) at the use of a wireless terminal. The final aim is the contribution in the design of wireless terminals (e.g. mobile telephones) that will be more efficient in their operation and simultaneously safer for their user. In this thesis, an extensive study and analysis of the parameters related with the interaction between the wireless terminal antenna and the user’s body were realized. Experimental terminal prototypes were designed, modelled, constructed and measured in the presence of human head models in order to estimate the radiation absorption from the head and the degradation of the antenna efficiency. An appropriate measurements methodology at the far field was developed for the precise measurement of the terminal antenna characteristics. According to the results, an intense change of the antenna characteristics and of its radiation diagram in the presence of the user’s head was observed. Also, the rapid decrease of absorbed power and the increase of the efficiency were calculated after moving the handset away from the head. An important operation improvement was achieved with beamforming, which is realized using multiple antennas at the terminal. Finally, the effect of the user’s hand at MIMO terminal performance was examined and a reduction of the mean capacity of the channel in the presence of the hand was found.

Full textThe Hellenides are part of the Alpine–Himalayan mountain chain in the eastern Mediterranean and form an orocline connecting the Dinarides to the north with the Anatolides/Taurides to the southeast. They comprise several continental fragments that were amalgamated by continent-continent collision between the Eurasian and Apulian plates during Late Mesozoic–Cenozoic times, following the obliteration of a series of intervening and interconnected Mesozoic ocean basins (Neo-Tethyan). The remnants of these ancient ocean basins are mainly represented by two narrow ophiolitic belts known as the Pindos and the Vardar sutures that divide the Hellenides into: (1) the External Zones, which represent the telescoped northern margin of the Apulia microcontinent; (2) the Internal Zones, which are built up by the Pelagonian zone and the Cycladic massif and (3) the Hellenic Hinterland, which is defined by the Serbomacedonian and the Rhodope massif. This dissertation concentrates in the area of southern and central/eastern Aegean in order to study the exhumation mechanism of high-pressure (HP) rocks, the role of compression and extension in the orogenic evolution of the Hellenides, the influence of pre-existing Mesozoic structures on the Cenozoic deformation pattern and to better understand the connection between the Hellenides and the Anatolides. To do so, geological and structural mapping were combined with kinematic, structural, paleostress (calcite twinning, fault-slip data), strain, petrofabric and vorticity analyses, carried out on central and western Crete island as well as on Amorgos and Astypalea islands. In central Crete, the evolution of windows was controlled by two main contractional phases of deformation. The first phase (D1) was related to the ductile-stage of exhumation. NNW-SSE compression during D1 caused layer- and transport-parallel shortening in the upper thrust sheets (Tripolitsa, Pindos and Uppermost units), resulting in nappe stacking via low-angle thrusting. Synchronously, intracontinental subduction led to HP metamorphism of the lower tectonic units (Plattenkalk and Phyllite-Quartzite units), which, however, did not affect the most external parts of the southern Hellenides. Subsequent upward ductile extrusion of HP-rocks was characterized by both down-section increase of strain and up-section increase of the pure shear component. The second phase (D2) was associated with the brittle-stage of exhumation. D2 was governed by NNE-SSW compression and involved conspicuous thrust-related folding, considerable tectonic imbrication and formation of a Middle Miocene basin. The major D2-related Psiloritis thrust, crosscuts the entire nappe pile and its trajectory partially follows and reworks the D1-related contact between upper and lower (HP) tectonic units. Eduction and doming of the Talea window, was accompanied by gravity sliding of the upper thrust sheets and by out-of-the syncline thrusting. Late-orogenic collapse also contributed to the exhumation process. Therefore, it seems that the HP-rocks of central Crete were exhumed under continuous compression and that the role of extension was previously overestimated. The structural architecture of western Crete was mainly established by two contractional deformation phases followed by an extensional phase. SSW-directed thrusting from Oligocene to Lower Miocene times (D1 phase) led to brittle stacking of the upper thrust sheets (Tripolitsa and Pindos units) and concomitant ductile exhumation-related imbrication of the lower HP tectonic units (Phyllite-Quartzite, Tripali and Plattenkalk units). Kinematic analysis in the Phyllite-Quartzite unit reveals a main southward ductile transport followed by late bulk coaxial deformation. Structural trends of ductile D1 thrusts define a salient bounded to the east by a NE-trending transverse zone (Omalos transverse zone) situated in the western margin of the Lefka Ori window. At the eastern limb of the salient, the trajectories of L1 stretching lineation formed on a gently dipping S1 foliation in the Phyllite-Quartzite unit, show a clockwise rotation with proximity to the transverse zone. This suggests that the latter might have acted as an oblique buttress against the southward extruding Phyllite-Quartzite unit rocks. D2 phase was governed by regional NNE to NNW compression related to a pure compressive to transpressive paleostress regime and involved significant folding and out-of-sequence with respect to D1 thrusting. The early D2a phase is related to the brittle-stage of exhumation of the HP-units and spans from Middle to Upper Miocene. D2a deformation involved thrust-related folding, tectonic imbrication and the formation of a Middle Miocene thrust-top basin, previously described as a supradetachment basin. The F2a folds are characterized by a predominant S(SE)-vergence and show a pronounced curvature of their hinge orientations from a regional E-W to a local NE-SW trend only present close to the transverse zone. In the latter, combined forward-directed imbricate thrusting and backthrusting led to the development of a major pop-up structure and a triangle zone, the latter cored by an Upper Miocene basin. Moreover, the trend of compression axes within the transverse zone are deflected from the regional NNE to NNW orientation to a local (W)NW orientation, which is perpendicular to the transverse zone. These findings suggest that the Omalos transverse zone should have served as an oblique ramp to the southward transport of HP-rocks, while the steep dip of the ramp may has impeded displacement of the Phyllite-Quartzite unit rocks up the ramp acting as a buttress to their foreland propagation. The D2b phase lasted from Upper Miocene to Lower Pleistocene and involved SW-directed thrust-related folding and synchronous sinistral strike-slip faulting. The D2b-related paleostress field is characterized by a NE compression orientation defining a pure compressive to transpressive regime. During Pleistocene, compression gave its place to (W)NW transtension/pure extension. The described kinematic evolution of southern Hellenides in western Crete reveals that the NE-trending transverse zone, which is possibly aligned with an inherited rift-related Mesozoic fault system, exerted significant control on the deformation pattern at progressively shallower crustal levels. The Phyllite-Quartzite unit rocks comprise the body of an extruded crustal scale shear zone confined at its base by a major ductile thrust, the Basal thrust. New finite strain data from the thrust-sense shear zone were used to describe the variation of ductile strain with structural distance (D) from the Basal thrust. Sampling was carried out along three traverses across central and western Crete. The strain ratio in XZ sections (RXZ) was obtained using the theta-curve, the mean object ellipse and the mean radial length methods. All methods give very consistent results. Based on these results, three strain profiles were constructed depicting a non-linear increase of RXZ values with proximity to the Basal thrust. Based on these profiles, an empirical logarithmic function of equation type RXZ=α−βlnD was obtained, describing the relationship between RXZ and D. Deformation in both central and western Crete occurred under approximately plane strain conditions, although deviations towards the fields of constriction and flattening have also been recorded. The vorticity profiles above the Basal thrust plane show a down section increase in the kinematic vorticity number (Wm) from 0.5 to 1 in western Crete and a simple shear-dominated deformation with the presence of local domains with a higher pure shear component in central Crete. A transport-parallel elongation of 20−110% has been estimated for the Phyllite-Quartzite unit, implying that S-directed extrusive flow controlled the formation and exhumation of the Phyllite-Quartzite thrust-sense shear zone. In central Aegean, the Cycladic island of Amorgos consists of two HP-units, the marble-rich Amorgos unit, which is correlated to the Mesozoic cover sequence of the Menderes massif, and the Cycladic Blueschist unit. The field-based structural study shows that the deformation history of the Amorgos HP-rocks was principally governed by Upper Eocene−Lower Miocene ductile to brittle thrusting (D1−D3) followed by Middle−Upper Miocene oblique contractional movements (D4−D5). The D1 phase caused syn-blueschist-facies ductile thrusting of the Cycladic Blueschist unit over the Amorgos unit, with ambiguous kinematics. Progressive deformation under continuous NW-SE compression produced a sequence of imbricate NW-directed thrusts (D2/3) characterized by a stratification of fault-related rocks, with mylonitic zones (D2) giving way downwards to cataclastic zones (D3). Parallelism between slickenside lineations and mylonitic L2 lineations in the D2/3 thrust zones, indicates a continuum of kinematics from ductile to brittle conditions. Ductile D2 thrusting synchronous to greenschist-facies retrogression, was accompanied by mega-sheath folding during constrictional and pure-shear dominated deformation. Brittle D3 thrusting was associated with NW-verging F3 folds trending at high-angle to the transport direction. Orthogonal contraction gave its place to transpression during which the compression orientation changed from NW-SE (D4) to NE-SW (D5). Back-arc related NW-SE pure extension (D6) seems to have been established in post-Upper Miocene times and related high-angle normal faulting affected HP-rocks only after they had already reached the uppermost crustal levels. Therefore, a syn-compressional exhumation process is favored for the HP-rocks of Amorgos island. In eastern Aegean, the island of Astypalea consists of Cretaceous to Eocene carbonate rocks capped by an Upper Eocene flysch, the Astypalea unit, which is correlated to the Mesozoic cover sequence of the Menderes massif and of tectonically overlying Jurassic marbles, which are considered as lateral equivalent of part the Lycian nappes. The deformation history of Astypalea was governed by Oligocene−Lower Miocene thrusting (D1) followed by Middle−Upper Miocene oblique contractional movements (D2) that in turn gave their place to post-Upper Miocene extension (D3, D4). The D1 phase caused NW-directed ductile to brittle thrusting of the Jurassic marbles over the Astypalea unit under continuous NW-SE compression. The stratification of fault-related rocks, with a mylonitic (D1a) upper and a cataclastic (D1b) lower part, as well as the parallelism between slickenside lineations and mylonitic L1a lineations in the D1 thrust zone, indicates a continuum of kinematics from ductile to brittle conditions. In the thrust zone footwall, brittle D1b thrusting was associated with NW-verging F1b folds that refold isoclinal F1a folds. Orthogonal contraction gave its place to WNW triclinic transpression (D2) during which deformation was partitioned in contraction-dominated (NE contraction) and wrench-dominated (NW-directed shearing) domains. N-S transtension to pure extension (D3) seems to have been established in Pliocene times and was followed by WNW transtension possibly active from post-Middle Pleistocene till present. Summarizing, the HP-rocks of southern and central Aegean were exhumed under continuous compression, albeit with opposite kinematics. Compression governed deformation throughout Oligocene to Lower Pliocene (Amorgos, Astypalea) or Lower Pleistocene (Crete) and the area was subjected to transtension/pure extension from Plio-Pleistocene onwards. Therefore, the role of extension in the exhumation of HP-rocks and the orogenic evolution of southern and central/eastern Aegean seems to be overestimated.

Full textIn this thesis, an effort of presenting the technological landscape of the telecommunication market takes place, with focus on the interoperability between the Mobile Telephony Networks and the Wireless Data Networks and the relative changes that have evolved through this interoperability, both regarding the provided services and the applied business models by the enterprises of the specific market. Within the frames of this effort, a detailed recording of technological developments is realised, in terms of technical specifications and standards, in the two aforementioned categories of networks, so as to conclude to those standards that are utilized by the next generation networks (4G) which will be: • Networks that will be unified so as the different technological platforms will function smoothly. • Networks that will be characterized by low cost of deployment. • The end user will be continuously connected with a wireless access network, enjoying the preferred services anywhere and anytime. The master thesis structure follows the aforementioned methodology. The 1st Chapter includes a short presentation of expected results, both in terms of technologies and services for next generation networks, which we usually refer to as 4G networks (4th Generation) or B3G networks (Beyond 3G) or finally as All - IP wireless networks (AIPN). In the 2nd Chapter, a detailed presentation of Mobile Telephony Networks takes place, from their first versions (1G) until the most modern (3.5G) that have been presented up to today. The analysis includes both the various generations of networks and the used standards, in terms of modulation and multiplexing techniques. The rest of the chapter focuses on the technical description of the prevailing networks, GSM, GPRS and UMTS, while the chapter ends with a short description of intersystem handover processes between GSM and UMTS. Τhe 3rd Chapter, includes an extensive description of the Wireless Data Networks standards such as: IEEE 802.15 Wireless Personal Area Networks (WPANs) with main representatives networks based on Bluetooth and IrDA, standard IEEE 802.11 Wireless Local Area Networks (WLANs) mainly represented by WiFi and HyperLan/2, IEEE 802.16 Wireless Metropolitan Area Networks (WMANs) standard, widely known as WiMax and finally the IEEE 802.20 Wireless Wide Area Networks (WWANs) standard, namely Mobile Broadband Wireless Access (MWBA) that is still under development and aspires to constitutes the wireless version of the xDSL technology, since it aims to provide wireless broadband services. In the 4th Chapter methodologies for integrating the two types of networks, are presented along with examples of interoperability between GPRS / UMTS and WLANs or between UMTS and WiMAX. Extensive discussion around the problems that should be faced, as the guarantee of bearable QoS level, the mechanisms for handover between the networks and the management of mobility of users and terminals, is held. Moreover, examples of integrated networks with both loose and tight coupling methodologies are presented. The last section of the chapter concerns a detailed description of architectures for interconnecting heterogeneous wireless networks over IP – based backhaul networks, namely All – IP networks, with special focus on policy based handover mechanisms and techniques for managing micromobility and macromobility issues. The 5th Chapter concerns the changes taking place in the telecommunications market deriving from the technological progress in the subject of heterogeneous wireless networks interconnection. New service packets are created, as a result of new business plans that are drawn up by the big telecommunications organizations. Finally, we present the developments in the Greek market and subsidised projects from Information Society AE, via which wireless networks have been materialised, with aim to promote Broadband Services.
