Abstract:
Ternary borate glasses from the system Na2O?CaO?B2O3 together with soda-lime-borate samples containing 5 wt.% of MgO, Al2O3, SiO2 or P2O5 were prepared. The obtained glasses were converted to their glass-ceramic derivatives by controlled heat treatment. X-ray diffraction was employed to investigate the separated crys?talline phases in glass-ceramics after heat treatment of the glassy samples. The glasses and corresponding glass-ceramics after immersion in water or diluted phosphate solution for extended times were characterized by the grain method (adopted by several authors and recommended by ASTM) and Fourier-transform infrared spectra to justify the formation of hydroxyapatite as an indication of the bone bonding ability. The influence of glass composition on bioactivity potential was discussed too.

Abstract:
Borate glasses with the basic composition 0.6B2O3?0.2Na2O?0.2CaO and SrO progressively substituting CaO were prepared and characterized for their bone-bonding ability. The obtained glasses were thermally treated and converted to their glass-ceramic derivatives. In this study, FTIR spectral analyses were done for the prepared glasses and glass-ceramics before and after immersion in a sodium phosphate solution for extended times. The appearance of two IR bands within the spectral range 550-680 cm-1 after immersion confirms the formation of hydroxyapatite. X-ray diffraction studies and scanning electron microscope analysis supported the obtained infrared spectroscopy results. The solubility test (measurements of the weight loss in aqueous sodium phosphate solution) was conducted for measuring the dissolution of both glassy and crystalline derivatives to find out the role of SrO. The corrosion behaviour of the glasses and glass-ceramics indicate the increase of weight loss with the increase of SrO content. Different suggested proposals were introduced to explain this abnormal behaviour.

Abstract:
Bone, the organ that separates vertebrates from other living beings, is a complex tissue responsible of mobility, body stability, organ protection, and metabolic activities such as ion storage. Ceramic materials are appropriate candidates to be used in the fabrication of scaffolds for bone healing. Biocompatible ceramic materials may also be created to deliver biologically active substances aimed at maintaining, repairing, restoring, or boosting the function of tissues and organs in the organism. Glass-ceramic materials furnish flexible properties appropriate for some particular applications. Because of the controlled devitrification and the evolution of variable dimensions of crystalline and glassy phases, glass-ceramics considerably overcome the lacunae found in glasses. A wide range of bioactive glass compositions had been developed since the early 1970s to make them appropriate for many clinical applications. Many bioactive ceramic composite materials attach to living bone through an apatite layer, which is developed on their surfaces in the living body. This paper reviews the most used bioactive ceramics for bone tissue regeneration, with specific accentuation on the material characteristics.

Abstract:
Calcium phosphate glasses have a high potential for use as biomaterials because their composition is similar to that of the mineral phase of bone. Phosphate glasses can dissolve completely in aqueous solution and can contain various elements owing to their acidity. Thus, the glass can be a candidate for therapeutic ion carriers. Recently, we focused on the effect of strontium ions for bone formation, which exhibited dual effects of stimulating bone formation and inhibiting bone resorption. However, large amounts of strontium ions may induce a cytotoxic effect, and there is a need to control their releasing amount. This work reports fundamental data for designing quaternary CaO-SrO-P2O5-TiO2 glasses with pyro- and meta-phosphate compositions to control strontium ion-releasing behavior. The glasses were prepared by substituting CaO by SrO using the melt-quenching method. The SrO/CaO mixed composition exhibited a mixed cation effect on the glassification degree and ion-releasing behavior, which showed non-linear properties with mixed cation compositions of the glasses. Sr2+ ions have smaller field strength than Ca2+ ions, and the glass network structure may be weakened by the substitution of CaO by SrO. However, glassification degree and chemical durability of pyro- and meta-phosphate glasses increased with substituted all CaO by SrO. This is because titanium groups in the glasses are closely related to their glass network structure by SrO substitution. The P-O-Ti bonds in pyrophosphate glass series and TiO4 tetrahedra in metaphosphate glass series increased with substitution by SrO. The titanium groups in the glasses were crosslink and/or coordinate phosphate groups to improve glassification degree and chemical durability. Sr2+ ion releasing amount of pyrophosphate glasses with >83% SrO substitution was larger than 0.1 mM at day seven, an amount that reported enhanced bone formation by stimulation of osteogenic markers.

Abstract:
Abstract Glass ionomer cements (GIC) are used in restorative dentistry and their properties (low heat during setting, adhesion to mineralised tissue and surgical metals) make them of great interest for bone applications.However, dental GIC are based on aluminium-containing glasses, and the resulting release of aluminium ions from the cements needs to be avoided for applications as bone cements. Replacing aluminium ions in glasses for use in glass ionomer cements is challenging, as aluminium ions play a critical role in the required glass degradation by acid attack as well as in GIC mechanical stability. Magnesium ions have been used as an alternative for aluminium in the glass component, but so far no systematic study has looked into the actual role of magnesium ions. The aim of the present study is therefore the systematic comparison of the effect of magnesium ions compared to calcium ions in GIC glasses. It is shown that by partially substituting MgO for CaO in simple SiO2-CaO-CaF2 glasses, ion release from the glass and, subsequently, GIC setting behaviour can be adjusted. Magnesium ions act as typical network modifiers here but owing to their larger field strength compared to calcium ions reduce ion release from the glasses significantly. By choosing an optimum ratio of magnesium and calcium ions in the glass, GIC setting and subsequently compressive strength can be controlled.

Abstract:
Fluoride is an important mineral for hard tissues in the body and appropriate fluoride exposure and usage are beneficial to bone and tooth integrity. Fluoride increases both bone density and bone mass due to stimulation of bone formation and it is used as a treatment for osteoporosis. Bioactive glasses have the capacity to form an intimate bond with living bone tissue due to formation of a mixed hydroxycarbonate apatite layer (HCA) in vitro and in vivo. This makes fluoride-containing bioactive glasses attractive biomaterials. In order to design fluoride-containing bioactive glasses, we need to understand the role of fluorine within the glass structure. A series of bioactive glasses with increasing fluoride content was prepared by a melt-quench route. Characterisation included differential scanning calorimetry (DSC), density measurements, MASNMR spectroscopy and studies in simulated body fluid (SBF). DSC results showed a linear decrease in glass transition temperature (Tg) with increasing amounts of fluoride. Density of the glasses increased with increasing amounts of fluoride. This may indicate an expansion of the silicate glass network accompanying incorporation of CaF2. 19F MAS-NMR spectroscopy showed broad peaks at chemical shifts between -135 and -120 ppm. As sodium fluoride gives a chemical shift of -223 ppm and calcium fluoride of -108 ppm, this indicated possible formation of mixed calcium sodium fluoride species. HCA and calcium phosphate layers were found on the glasses after one week of immersion in SBF showing the bioactivity of the glass series.

Abstract:
According to the Global Burden of Diseases, Injuries, and Risk Factors Study, cases of bone fracture or injury have increased to 33.4% in the past two decades. Bone-related injuries affect both physical and mental health and increase the morbidity rate. Biopolymers, metals, ceramics, and various biomaterials have been used to synthesize bone implants. Among these, bioactive glasses are one of the most biomimetic materials for human bones. They provide good mechanical properties, biocompatibility, and osteointegrative properties. Owing to these properties, various composites of bioactive glasses have been FDA-approved for diverse bone-related and other applications. However, bone defects and bone injuries require customized designs and replacements. Thus, the three-dimensional (3D) printing of bioactive glass composites has the potential to provide customized bone implants. This review highlights the bottlenecks in 3D printing bioactive glass and provides an overview of different types of 3D printing methods for bioactive glass. Furthermore, this review discusses synthetic and natural bioactive glass composites. This review aims to provide information on bioactive glass biomaterials and their potential in bone tissue engineering.

Abstract:
Bioactive glass scaffolds are used in bone and tissue biomedical implants, and there is great interest in their fabrication by additive manufacturing/3D printing techniques, such as robocasting. Scaffolds need to be macroporous with voids ≥100 m to allow cell growth and vascularization, biocompatible and bioactive, with mechanical properties matching the host tissue (cancellous bone for bone implants), and able to dissolve/resorb over time. Most bioactive glasses are based on silica to form the glass network, with calcium and phosphorous content for new bone growth, and a glass modifier such as sodium, the best known being 45S5 Bioglass®. 45S5 scaffolds were first robocast in 2013 from melt-quenched glass powder. Sol–gel-synthesized bioactive glasses have potential advantages over melt-produced glasses (e.g., greater porosity and bioactivity), but until recently were never robocast as scaffolds, due to inherent problems, until 2019 when high-silica-content sol–gel bioactive glasses (HSSGG) were robocast for the first time. In this review, we look at the sintering, porosity, bioactivity, biocompatibility, and mechanical properties of robocast sol–gel bioactive glass scaffolds and compare them to the reported results for robocast melt-quench-synthesized 45S5 Bioglass® scaffolds. The discussion includes formulation of the printing paste/ink and the effects of variations in scaffold morphology and inorganic additives/dopants.

Abstract:
Resorbable calcium phosphate glasses offer interesting solutions in the biomedical field, as bone cavity fillers, drug delivery systems, biodegradable reinforcing phase in the case of composites for bone fixation devices and tissue engineering scaffolds. In this work, two different glass formulations in the systems 44.5CaO-44.5P2O5-(11-X)Na2O-XTiO2 (X=0or 5) have been elaborated. It is known that the incorporation or TiO2 into the vitreous system reduces considerably the solubility of the glasses. To study the material solubility effect on the in vivo response, glass particles of the two formulations were implanted in rabbits. Results showed that both glasses elicited a similar biological response and good biocompatibility. The percentage of new bone formation in the glasses was comparable to that obtained for the autologous bone (control) after 12 weeks of implantation. The materials showed to have an osteoconductive potential. Finally, this study showed that in spite of the solubility difference of the studied glasses, there were no significant differences in the in vivo response.

Abstract:
Glass‐ionomer cements (GICs) are acid base reaction cements used in dentistry for restorative applications. In conventional GICs aluminosilicate glass is used to react with a polyalkenoic acid such as poly acrylic acid. Glass–ionomer cements have the potential to be used for bone cement applications, however there is a concern over the neurotoxicity of aluminium in the glass component of these cements. In this work zinc containing phosphate glass based glass–ionomer cement has been developed for the bone cement application. In this relation structure of zinc containing phosphate glasses in the system Na2O:CaO:ZnO:P2O5 ranging from metaphosphate compositions to invert phosphate compositions has been examined. Various advanced techniques in solid state nuclear magnetic resonance (NMR) such as dipolar recoupling and solid state NMR of low  quadrupolar nuclei (67Zn and 43Ca) and neutron diffraction have been employed. Special emphasis has been focused on structural role of zinc in glasses of different composition and the effect of different cations on coordination of zinc along with the effect on phosphate tetrahedra. 67Zn and 43Ca solid state NMR spectra of selected glass samples have been successfully acquired at ultrahigh field 900 MHz using Solid Echo pulse sequence. In addition solid state NMR spectra of two polymorphs of crystalline Zn(PO3)2 have also been acquired at 850 MHz using DFS– WURST–QCPMG pulse sequence in order to distinguish between the magnitude and orientation of electric field gradient (EFG) of zinc in octahedral and tetrahedral coordination. Structure determined through various techniques has been related to the dissolution behaviour of glass compositions from metaphosphate to invert phosphate. A decrease in pH of surrounding medium has been observed due to the presence of zinc. Insertion of ZnO4 tetrahedra between PO4 tetrahedra has been observed in invert phosphate glasses with high zinc oxide content which renders them suitable for glass– ionomer cements. Glass–ionomer cement from glass composition 10Na2O:50ZnO:10CaO:30P2O5 and hydroxyapatite and, acrylic acid and vinyl phosphonic acid co‐polymer has been produced successfully.

Doutoramento em Ciência e Engenharia dos Materiais
Bioactive glasses and glass-ceramics are a class of third generation biomaterials which elicit a special response on their surface when in contact with biological fluids, leading to strong bonding to living tissues. The purpose of the present study was to develop diopside based alkali-free bioactive glasses in order to achieve good sintering behaviour, high bioactivity, and a dissolution/ degradation rates compatible with the target applications in bone regeneration and tissue engineering. Another aim was to understand the structure-property relationships in the investigated bioactive glasses. In this quest, various glass compositions within the Diopside (CaMgSi2O6) – Fluorapatite (Ca5(PO4)3F) – Tricalcium phosphate (3CaO•P2O5) system have been investigated. All the glasses were prepared by melt-quenching technique and characterized by a wide array of complementary characterization techniques. The glass-ceramics were produced by sintering of glass powders compacts followed by a suitable heat treatment to promote the nucleation and crystallization phenomena. Furthermore, selected parent glass compositions were doped with several functional ions and an attempt to understand their effects on the glass structure, sintering ability and on the in vitro bio-degradation and biomineralization behaviours of the glasses was made. The effects of the same variables on the devitrification (nucleation and crystallization) behaviour of glasses to form bioactive glass-ceramics were also investigated. Some of the glasses exhibited high bio-mineralization rates, expressed by the formation of a surface hydroxyapatite layer within 1–12 h of immersion in a simulated body fluid (SBF) solution. All the glasses showed relatively lower degradation rates in comparison to that of 45S5 Bioglass®. Some of the glasses showed very good in vitro behaviour and the glasses co-doped with zinc and strontium showed an in vitro dose dependent behaviour. The as-designed bioactive glasses and glass–ceramic materials are excellent candidates for applications in bone regeneration and for the fabrication of scaffolds for tissue engineering.
Os vidros e vitrocerâmicos bioactivos fazem parte da chamada terceira geração de biomateriais, i.e., materiais que estimulam uma resposta especial quando em contacto com fluidos biológicos, capaz de conduzir ao estabelecimento de ligações fortes entre a sua superfície e os tecidos vivos. O presente estudo visou o estudo e desenvolvimento de vidros bioactivos à base de diópsido e isentos de metais alcalinos que apresentem um bom comportamento na sinterização, elevados índices de bioactividade, e taxas de dissolução / degradação compatíveis com as almejadas aplicações em regeneração óssea e em engenharia de tecidos. Procurou-se ainda entender as relações entre a estrutura e as propriedades dos vidros bioactivos estudados. De acordo com esta perspectiva, estudaram-se várias composições de vidros bioactivos pertencentes ao sistema Diópsido (CaMgSi2O6) – Fluorapatite (Ca5(PO4)3F) – Fosfato de tricálcico (3CaO•P2O5). Todas as composições vítreas foram preparados por fusão, seguida de fritagem em água fria, e caracterizados através de um conjunto de técnicas complementares de caracterização. Os vitrocerâmicos foram obtidos por sinterização das fritas de vidro moídas e compactadas, seguida de tratamento térmico adequado para promover os fenómenos de nucleação e cristalização. Além disso, algumas composições vítreas seleccionadas foram dopadas com vários iões funcionais e os seus efeitos na estrutura vítrea, na sua propensão para a sinterização, e nos comportamentos in vitro em termos de biodegradação e bio-mineralização foram avaliados. Os efeitos das mesmas variáveis no processo de devitrificação (nucleação e cristalização) dos vidros e formação de materiais vitrocerâmicos foram também investigados. Algumas composições de vítreas apresentaram taxas de bio-mineralização elevadas, expressas através da formação de camadas superficiais de hidroxiapatite após 1-12 h de imersão num fluido fisiológico simulado (SBF). Todas as composições vítreas apresentaram taxas de degradação mais baixas quando comparadas com a do 45S5 Bioglass®. Alguns vidros bioactivos revelaram comportamentos in vitro excelentes, sendo a taxa de biomineralização dos co-dopados com zinco e estrôncio dependente da dose incorporada de dopantes. Os materiais estudados demostraram boa aptidão para aplicações em regeneração óssea e para o fabrico de estruturas de suporte em engenharia de tecidos.

Abstract:
We use Monte Carlo simulations in order to investigate the density of states and the two-time density autocorrelation function for the two- and three-dimensional Coulomb glass as well as the Bose glass phase of flux lines in type-II superconductors. We find a very fast forming gap in the density of states and explore the dependence of temperature and filling fraction. By studying two scaling methods, we find that the nonequilibrium relaxation properties can be described sufficiently by a full-aging scaling analysis. The scaling exponents depend on both temperature and filling fraction, and are thus non-universal. We look at the trends of these exponents and found that as either the temperature decreases or the filling fraction deviates more from half-filling, the exponents reflect slower relaxation kinetics. With two separate interaction potentials, a comparison of relaxation rates and the gap in the density of states is made.

Abstract:
Phosphate glass with additions of sodium, magnesium and/or calcium were investigated for their potential to be used as the reinforcing phase in a completely degradable long fibre composite. Glasses were prepared from phosphate salts as opposed to oxides and melted under air in platinum/gold crucibles. The effect of cation addition on the material properties and biocompatibility was investigated. Glasses were characterised using a number of complimentary techniques, including: XRD, XPS, DSC, IR and EDX. The findings from these techniques were used to explain the observed thermal and dissolution properties. The thermal and dissolution properties were found to be dependant on both the thermal history and composition of the phosphate glass. For a phosphate glass with low cation content, the temperature and length of time held at that temperature increased the Tg by 10 C for sodium phosphate glass and slightly improved the durability of sodium phosphate glass containing 10 mol.% MgHPO4, as phosphate chain growth was greater under those conditions. Addition of divalent cations increased the Tg of phosphate glasses from 295 C for sodium phosphate glass by up to 150 C with the addition of 50 mol.% MgHPO4. The dissolution rate was decreased exponentially with the addition of calcium phosphate or magnesium phosphate to sodium phosphate glass. Rates as low as 1x10-7 g/(cm2.h) were achieved with the addition of 50 mol.% divalent cation phosphates. The divalent cations inhibited phosphate chain growth but formed a new network based upon divalent cation/non bridging oxygen cross-links. These cross-links were found to exert greater influence over the material properties then the phosphate chain length. Cell culture assays were used to establish the biocompatibility of phosphate glasses with different compositions. Preliminary tests were conducted with craniofacial derived osteoblast like cells cultured on glass surfaces. Initial assays performed showed that the most durable glasses sustained the greatest amount of proliferation and differentiation over a seven day period. The most promising glass compositions, 40 Ca, 40 Mg, 30 Mg/20 Ca and 20 Mg/30 Ca, and were selected for longer term osteoblast culture and short term macrophage culture. Long term osteoblast culture showed that cells were able to attach, spread and proliferate throughout the 28 day duration of the study. Assays performed on the culture showed that cells were differentiating, producing specific osteoblast markers for each of the three differentiation phases of proliferation, matrix maturation and mineralisation. ECM production and mineralisation was confirmed on all surfaces tested via type I collagen staining and alizarin red staining respectively. Over the 28 day period, it was found that the composition did not have a significant effect on the production of the osteoblast markers, namely alkaline phosphatase, collagen, osteocalcin and mineral deposition. Immunological studies show that macrophages are not activated by the presence of phosphate glass. This demonstrated that phosphate glass has shown potential for use a biomaterial.

Abstract:
Les effets conjoints du désordre (i.e. des impuretés) et des interactions constituent une des questions les plus fondamentales de la Physique de la Matière Condensée qui a reçu énormément d'attention dans les dernières décennies. La transition de phase quantique du Superfluide vers le verre de Bose déclenchée par le désordre s'est révélée énigmatique tant pour les théoriciens que pour les expérimentateurs et des questions restent ouvertes malgré tous leurs efforts. Les travaux présentés dans ce manuscrit abordent certaines de ces questions pour deux modèles de bosons de coeur dur désordonnés à deux dimensions : valeurs des exposants critiques qui gouvernent la transition ; propriétés inhomogènes des phases en compétition ; scénario physique au point critique ; propriétés de localisation des excitations bosoniques. On utilise trois approches différentes pour la transition afin d'explorer ce problème. En premier lieu, on montre comment les fractions superfluide et du condensat de Bose-Einstein sont affectées par le désordre dans une approximation de Champ Moyen qui, bien qu'incapable de capturer la transition, donne accès à des caractéristiques qualitatives intéressantes. En se basant sur cette solution Champ Moyen, on introduit les fluctuations quantiques à travers une théorie d'ondes de spin linéaires dans l'espace réel qui capture la transition et dévoile un comportement non trivial du spectre d'excitations. Finalement, on explore minutieusement la région critique quantique par des simulations de Monte Carlo Quantique à l'état de l'art, menant à une évaluation précise des exposants critiques et à une surprenante absence d'auto-moyennation dans le régime du verre de Bose
The interplay of disorder (i.e. impurities) and interactions is one of the most fundamental questions in Condensed Matter Physics that has received a lot attention in the past couple of decades. The quantum phase transition from Superfluid to Bose glass driven by disorder has puzzled theoreticians and experimentalists alike, leaving unresolved questions despite their best efforts. The work presented in this thesis addresses some of these questions for two models of disordered hard-core bosons in two dimensions. In particular, the values of the critical exponents governing the transition, the inhomogeneous properties of the competing phases, the physical scenario at criticality and the bosonic excitations' localization properties are investigated. Three different approaches to the transition are used to explore this problem. We first show how Bose-condensate and superfluid fractions are affected by disorder in a Mean-Field approximation, which is unable to capture a transition, but reveals interesting qualitative features. Building on such a Mean-Field solution, quantum fluctuations are then introduced using a linear spin-wave theory in real space which does capture the transition and furthermore unveils a non-trivial behavior for the excitation spectrum. Finally, the quantum criticality is explored in great detail using state-of-the-art Quantum Monte Carlo simulations, leading to a precise evaluation of the critical exponents and a surprising absence of self-averaging in the Bose glass regime

Abstract:
In bone tissue engineering, one of the main challenges is to fabricate scaffolds that promote and support osseous reconstruction. The research reported in this thesis considers the use of apatite-wollastonite (A-W) as a bone scaffold. A variety of scaffold fabrication techniques, all based on initially processing powder to create a pre-form for subsequent sintering, have been developed and characterised for their ability to create microporous; and interconnected macroporous scaffolds. A range of powder processing techniques were used: pelleting, dry powder and slurry moulding, and different powder particle size ranges were assessed for the preparation of microporous scaffolds to influence their surface roughness without significantly varying the porosity. To introduce macroporosity within the ceramic scaffolds that would be comparable in terms of scale and organisation to trabecular bone, a variety of methods were employed. Burning off negative templates such as polymeric particles, filaments and fused deposition modelling 3D constructs was investigated, together with a novel method based on thermally induced phase separation (TIPS), freeze-drying and sintering. Selected microporous scaffolds with different surface topography and pore size; and highly interconnected scaffolds with porosity >80% were fabricated with height 2± 0.1 mm and diameter 8- 10 mm depending on the fabrication method and the particle range that was used. The parameters that were evaluated in vitro were the effect of variable topographies on microporous constructs and the influence of high porosity on cell adhesion, proliferation and cell differentiation. It is concluded that the surface area of A-W scaffolds affects their bioactivity, degradation and mechanical properties. Microporous scaffolds with smaller pores allow cell-cell interaction and promote osteogenesis. Further investigation is required to clarify the observed chondrogenesis that occurred when MSCs were cultured on microporous scaffolds with larger pores. Highly porous A-W scaffolds allow cell infiltration, migration and demonstrate signs of osteochondral lineage differentiation.

Abstract:
Abstract Equation of state properties were studied for the high-lead glass Corning 0120, which is a potash-soda-lead glass also referred to as G12. This glass, which contains approximately 30% PbO by weight and has a density, ρo, of 3.034 g/cm3 possesses properties suitable for many applications in industry such as optical components for space exploration instrumentation. Further understanding of its mechanical properties is desired for more complex applications in various fields, including applications where the glass may experience high-pressure shock loading. In this work plate impact experiments were conducted to determine the dynamic response of Corning 0120 at high stress levels. Tests were conducted over the pressure range from approximately 5 to 24 GPa utilizing the 90 mm bore single-stage powder driven gas gun at the Sandia National Laboratories STAR Facility. For this study, we used one-inch diameter Corning 0120 glass samples of two different thicknesses (3 mm and 7 mm) to use the evolution of the shock wave propagation through the material for analysis. The time-resolved material response was measured by means of a Velocity Interferometer System for Any Reflector system (VISAR). Results will be presented detailing the high-pressure shock loading response characteristics of the high-lead glass Corning 0120. Comparisons are made with similar results for lead free glass to assess the most prominent changes compared to lower density glasses and other lead filled glasses.

Abstract:
Izborni sistem Bosne i Hercegovine se smatra specifičnim iz nekoliko razloga, a njegov sadržaj od samog uspostavljanja bio je do sada na različite načine problematiziran. Jedan od ograničavajućih faktora ovog sistema, koji je u suprotnosti s univerzalnim i jednakim pravom glasa, sadržan je u odredbi da je to pravo zasnovano na etničkoj pripadnosti. Pored toga, ograničenje ovog prava dodatno je pojačano činjenicom da je pravo kandidiranja usko limitirano mjestom prebivališta, odnosno entitetskim granicama. Političko predstavljanje u Bosni i Hercegovini je gotovo u potpunosti određeno i ograničeno principom konstitutivnosti koji dominantno etnički kroji bosanskohercegovački politički prostor onemogućujući na taj način uspostavljanje koherentnog društvenog i političkog tkiva u BiH.

Abstract:
Bone cells are adaptive to surrounding mechanical conditions. Osteoblasts, one of bone cells, have been reported to be sensible to mechanical stimulation and change the generated bone mass. Viscoelastic properties of such cells are predicted to be related to this phenomenon in the view of mechanical dynamics. In order to find the effective stimulation on the bone formation, it is necessary to understand the viscoelastic properties of the cells. Especially in the case of bone cells, it is important to consider their adhesive condition because they attach on surfaces of bone matrices. In this study, we measured dynamic viscoelastic properties of a cultured osteoblast, MC3T3-E1, under adhesive condition. Using the experimental results, we derived a model for viscoelasticity of the cell and identified the value of each element in this model. The cells were seeded on a glass plate in a petri dish. After the cells were cultured for one day and adhered on the glass plate, it was vertically raised and fixed on a piezo actuator. The center of the cell surface was aspirated with an L-shaped micropipette to be held. The glass plate was moved with the piezo actuator. The load applied to the cell was obtained by measuring the deflection of the micropipette whose spring constant was calibrated after each test. Deflection of the micropipette and elongation of the cell were measured by captured image during the test. As a result, the dynamic viscoelasticity of the cells was measured and modeled, and the value of each element in this model was identified.

Abstract:
Non-intrusive techniques such as medical CT-Scan or micro-CT allow the definition of 3D connected pore networks in porous materials, such as sedimentary rocks or concrete. The definition of these networks is a key step towards the evaluation of fluid flow and heat transfer in energy resource (e.g., hydrocarbon and geothermal reservoirs) and CO2 sequestration research projects. As material heterogeneities play a role at all scales (from micro- to project-scale), numerical models represent a powerful tool for bridging the gap between small-scale measurements provided by X-ray imaging techniques and larger-scale transport properties. This study uses pre-existing medical CT-scan datasets of reference material, namely glass beads and conventional reservoir rocks (Berea sandstone, Boise sandstone, Indiana limestone) to extract the 3D geometry of connected pores using an open-source software (Spam). Pore networks from rock samples were generated from dry and then saturated samples. Binarized datasets were produced for these materials (generated by a thresholding technique) to obtain pore size distribution and tortuosity, as well as preferential paths for fluid flow. Average porosities were also calculated for comparison with those obtained by conventional commercial laboratory techniques. The results obtained show that this approach works well for medium and coarse-grained materials that do not contain a large percentage of fine particles. However, this approach does not allow representative networks to be obtained for fine-grained rocks, due to the fact that small pores (or pore throats) cannot be taken into account in the datasets obtained from the medical CT-Scan. A next step, using datasets produced from a micro- CT scan, is planned in order to be able to generate representative networks in this type of material as well.
