Abstract:
We have previously modeled pancreatic islet glycolysis under idealized steady-state conditions where the input is a pure hexose anomer and there is no mutarotation and reproduced the known preference for the alpha-anomers of glucose and mannose as substrates. This model is here extended to simulate real experiments, where the hexoses mutarotate and measurements may be taken over time. The behavior of our model system agrees with available experimental data. The hexose diphosphate activators of phosphofructokinase, whose effect was seen as not important in the preceding steady-state analysis, are found here to have a modest (approximately 10–15%) effect on its flux. The previous conclusion that the anomeric preference of the glycolytic pathway follows from that of glucokinase continues to hold in the real experimental situation.

Abstract:
ABSTRACT The two optical forms of aldohexose galactose differing at the C-1 position, α-d-galactose and β-d-galactose, are widespread in nature. The two anomers also occur in di- and polysaccharides, as well as in glycoconjugates. The anomeric form of d-galactose, when present in complex carbohydrates, e.g., cell wall, glycoproteins, and glycolipids, is specific. Their interconversion occurs as monomers and is effected by the enzyme mutarotase (aldose-1-epimerase). Mutarotase and other d-galactose-metabolizing enzymes are coded by genes that constitute an operon in Escherichia coli. The operon is repressed by the repressor GalR and induced by d-galactose. Since, depending on the carbon source during growth, the cell can make only one of the two anomers of d-galactose, the cell must also convert one anomer to the other for use in specific biosynthetic pathways. Thus, it is imperative that induction of the gal operon, specifically the mutarotase, be achievable by either anomer of d-galactose. Here we report in vivo and in vitro experiments showing that both α-d-galactose and β-d-galactose are capable of inducing transcription of the gal operon with equal efficiency and kinetics. Whereas all substitutions at the C-1 position in the α configuration inactivate the induction capacity of the sugar, the effect of substitutions in the β configuration varies depending upon the nature of the substitution; methyl and phenyl derivatives induce weakly, but the glucosyl derivative does not.

Abstract:
A novel application of 13C nuclear magnetic resonance provided the effects of solvent polarity and hydrogen-bond formation on the conformational equilibria for a range of 2-substituted tetrahydropyrans and the results are interpreted in terms of how solvent affects the competition between the endo- and exo-anomeric effects in determining the magnitude of the anomeric effect. In accord with the generally accepted origin of the endo- and exo-anomeric effects (anti-periplanar n–σ* interaction of the oxygen lone-pair orbital with the antibonding orbital of the adjacent C—O bond), the exo-anomeric effect for the α anomer is expected to be weaker because charge delocalization from the glycosidic oxygen to anomeric center is in competition with delocalization from the ring-oxygen atom. The effects of solvent on the relative magnitudes of the endo- and exo-anomeric effects are then considered to arise from the formation of specific complexes with the solvent, and the exo-anomeric effect of a β-glycoside is more strongly influenced. It is contended that hydrogen bonding of solvent to the ring oxygen increases the exo-anomeric effects. For this reason water is particularly effective for the strengthening of the exo-anomeric effect and, thereby, the conformational rigidity of glycosides. Experimental evidence is presented that indicates that the anomeric hydroxyl groups of free sugars dissolved in water tend to prefer the equatorial orientation because these provide stronger hydrogen bonds as proton donors to water.

Abstract:
In order to clarify the structural role of subsite B of hen egg-white lysozyme in hydrolytic activity towards a carbohydrate substrate, we analysed the structures of Trp-62 → Gly and Asp-101 → Gly mutant hen lysozymes, which have no side chain at positions 62 or 101, complexed with a substrate analogue, (N-acetyl-d-glucosamine)3 [(GlcNAc)3], using X-ray crystallography. The overall protein structures in the mutant lysozyme complexes were almost identical to those in the wild type. In the crystals of all the mutant complexes, the (GlcNAc)3 molecule, which is an inhibitor of wild-type lysozyme, had no inhibitory effect, but was hydrolysed as a substrate. One of the products, (GlcNAc)2, the reducing end of which is an α-anomer, was bound in an unproductive binding mode, protruding from the active-site cleft, and was able to act as an inhibitor. Hydrolysis of the synthetic substrate by the mutants occurred in a β-anomer-retaining manner, and so the α-anomer product was converted from the β-anomer product. Thus the interactions of Asp-101 and Trp-62 in subsite B are not essential for the catalytic mechanism, but co-operatively enhance the affinity of the substrate in the productive binding mode, other than the inhibitor in the unproductive mode.

Abstract:
Equilibrative sugar uptake in human erythrocytes is characterized by a rapid phase, which equilibrates 66% of the cell water, and by a slow phase, which equilibrates 33% of the cell water. This behavior has been attributed to the preferential transport of β-sugars by erythrocytes (Leitch JM, Carruthers A. Am J Physiol Cell Physiol 292: C974–C986, 2007). The present study tests this hypothesis. The anomer theory requires that the relative compartment sizes of rapid and slow transport phases are determined by the proportions of β- and α-sugar in aqueous solution. This is observed with d-glucose and 3- O-methylglucose but not with 2-deoxy-d-glucose and d-mannose. The anomer hypothesis predicts that the slow transport phase, which represents α-sugar transport, is eliminated when anomerization is accelerated to generate the more rapidly transported β-sugar. Exogenous, intracellular mutarotase accelerates anomerization but has no effect on transport. The anomer hypothesis requires that transport inhibitors inhibit rapid and slow transport phases equally. This is observed with the endofacial site inhibitor cytochalasin B but not with the exofacial site inhibitors maltose or phloretin, which inhibit only the rapid phase. Direct measurement of α- and β-sugar uptake demonstrates that erythrocytes transport α- and β-sugars with equal avidity. These findings refute the hypothesis that erythrocytes preferentially transport β-sugars. We demonstrate that biphasic 3- O-methylglucose equilibrium exchange kinetics refute the simple carrier hypothesis for protein-mediated sugar transport but are compatible with a fixed-site transport mechanism regulated by intracellular ATP and cell shape.

Abstract:
A series of 2-deoxy-2-iodo-α-d-mannopyranosylbenzotriazoles was synthesized using the benzyl, 4,6-benzylidene and acetyl protected D-glucal in the presence of N-iodosuccinimide (NIS). Subsequent removal of the iodine at the C-2 position using tributyltin hydride under free radical conditions afforded the 2-deoxy-α-d-glucopyranosylbenzotriazoles in moderate to high yields. This method was extended to the preparation of substituted 2-deoxy-β-d-glucopyranosylimidazoles as well. The stereoselectivity of the addition reaction and the effect of the protecting group and temperature on anomer distribution of the benzotriazole series were also investigated. The anticancer properties of the newly synthesized compounds were evaluated in a series of viability studies using HeLa (human cervical adenocarcinoma), human breast and lung cancer cell lines. The N-[3,4,6-tri-O-benzyl-2-deoxy-α-d-glucopyranosyl]-1H-benzotriazole and the N-[3,4,6-tri-O-acetyl-2-deoxy-α-d-glucopyranosyl]-2H-benzotriazole were found to be the most potent cancer cell inhibitors at 20 µM concentrations across all four cell lines.

Abstract:
Here we report on the synthesis, biophysical properties and molecular modeling of oligonucleotides containing unsaturated 6’-fluoro[4.3.0]bicyclo nucleotides (6’F-bc4,3-DNA). Two 6’F-bc4,3 phosphoramidite building blocks (T and C) were synthesized starting from a previously described [3.3.0]bicyclic sugar. The conversion of this sugar to a gem-difluorinated tricyclic intermediate via difluorocarbene addition followed either by a NIS-mediated or Vorbrüggen nucleosidation yielded in both cases the β-tricyclic nucleoside as major anomer. Subsequent desilylation and cyclopropane ring opening of these tricyclic intermediates afforded the unsaturated 6’F-bc4,3 nucleosides. The successful incorporation of the corresponding phosphoramidite building blocks into oligonucleotides was achieved with tert-butyl hydroperoxide as oxidation agent. Thermal melting experiments of the modified duplexes disclosed a destabilizing effect versus DNA and RNA complements, but with a lesser degree of destabilization versus complementary DNA (ΔT m/mod = −1.5 to −3.7 °C). Molecular dynamics simulation on the nucleoside and oligonucleotide level revealed the preference of the C1’-exo/C2’-endo alignment of the furanose ring. Moreover, the simulation of duplexes with complementary RNA disclosed a DNA/RNA-type duplex structure suggesting that this modification might be a substrate for RNase H.

The 13C nmr spectra of solids, acquired using the Cross Polarization/Magic Angle Spinning (CP/MAS) technique, are very sensitive to the detailed nature of crystalline packing. These effects are illustrated in the CP/MAS spectra of the α and β anomers of methyl-D-xylopyranoside. In the spectrum of the α anomer, which crystallizes with two molecules per unit cell, individual spectra can be resolved for the two molecules in the asymmetric unit of this crystal.

Abstract:
The effects of α- and β-2-deoxy-d-glucose tetraacetate (1.7 and 8.5 mM) on insulin, somatostatin, and glucagon secretion from isolated rat pancreases perfused in the presence of 8.3 mM d-glucose were compared with those of unesterified 2-deoxy-d-glucose tested at the same two concentrations. The unesterified glucose analog caused, in a concentration-related manner, inhibition of glucose-induced insulin and somatostatin release and augmentation of glucagon secretion. The two anomers of 2-deoxy-d-glucose tetraacetate, however, increased the secretion rate of all three hormones; this effect was also related to the concentration of the esters. No obvious anomeric specificity of the secretory response to 2-deoxy-d-glucose tetraacetate was observed. These findings indicate that the insulinotropic action of hexose esters cannot be accounted for solely by the metabolic effect of their glucidic moieties. They suggest that the A, B, and D cells of the endocrine pancreas are each equipped with a receptor system responsible for the direct recognition of monosaccharide esters as secretagogues. They further support the view that a paracrine effect of insulin on glucagon-producing cells does not represent a major component in the regulation of their secretory activity.

Abstract:
Résumé : Au cours de cette thèse nous nous sommes intéressés à différentes propriétés de transport électrique, thermique et thermoélectrique. En particulier, nous avons mis en évidence les effets Righi-Leduc anomal et planaire qui sont les équivalents thermiques des effets Hall anomal et planaire. Ces effets doivent impérativement être considérés dans l’interprétation des mesures d’effet Seebeck de Spin.Nous avons mis à profit les techniques développées dans le cadre de cette étude pour étudier l’effet Nernst dans InSb. Nous avons utilsé un modèle de distribution de porteur pour expliquer les non-linéarités de celui-ci à des champs magnétiques proches de 1T.Nous avons construit une expérience de résonance ferromagnétique dont le but sera d’étudier les implications des effets thermique et thermoélectrique dans les expérience de pompage de spin. Enfin, nous nous sommes intéréssés au transport électrique en géométrie Corbino. La géométrie Corbino est celle d’un disque dans laquelle il n’existe aucun bord libre ou des charges peuvent s’accumuler. Cela se traduit par l’apparition d’un courant de Hall ortho-radial dont la conséquence est l’augmentation de la résistance du disque. Nous avons mis en évidence une augmentation de résistance en géométrie Corbino dans CoGd et CoTb dont l’origine est l’effet Hall anomale. Bien que cet effet ne soit pas dissipatif, il a donné naissance à un courant dissipatif transverse. Nous avons également vu que cet effet entre en compétition avec la magnétorésistance anisotrope dans le permalloy.Du fait de la similitude entre l’effet Hall anomal et l’effet Hall de spin, on s’attend dans le platine à l’existence d’un fort courant de spin orthoradial sans possibilités d’accumulations dont la mise en évidence expérimentale fera l’objet de travaux futurs
Abstract: During this PhD we studied different electric, thermal and thermoelectric properties. For instance, we characterized the anomalous and planar Righi-Leduc effects which are the thermal equivalent of the anomalous and planar Hall effects. These effect have to be taken into account when interpreting spin Seebeck measurements.We used the technics that we developped during this study to look at the Nernst effect in InSb. We developped, a carrier mobility distribution model to explain its non-linearity at fields around 1T.We built a ferromagnetic resonance experiment in order to study the impact of thermal and thermoelectric properties in spin pumping effect.Lastly, we studied electric transport in the Corbino geometry. Corbino geometry is the one of a disc where there are no free boundaries where electric charges can accumulate. This causes the apparition of an orthoradial Hall current which consequence is the increase of resistance of the disc. We showed an increase of resistance in the Corbino geometry in CoGd and CoTb originating from anomalous Hall effect. Despite the anomalous Hall effect does not dissipate, it produces an orthoradial current which dissipates. We also found in permalloy that this increase of resistance is counterbalanced by a decrease of resistance due to the anisotropic magnetoresistance.The similarity between anomalous Hall effect and spin Hall effect which share a common microscopic origin implies that we expect in platinum the apparition of an orthoradial spin current without possibility for the charges to accumulateition. This current should dissipate just the way it does for the anomalous Hall effect.The study of this spin current will be the topic of a futur study

Abstract:
A series of cermet powders of composition NixCo(1-x)O-YSZ were synthesized for testing as cermet anode materials for SOFCs. The Co is found by powder XRD to become incorporated into the crystal lattice of the NiO, thus forming a true alloyed material. SEM and EDS results show two types of particles upon sintering to 1380oC: small, amorphous particles of YSZ and large, crystalline particles of nickel. The electrochemical oxidation of hydrogen on a cermet anode composed of Ni0.7Co0.3O-YSZ was investigated using a series of many button cells. Through EIS data, cyclic voltammetry data, the exchange current densities for these button cells were determined. Although a relatively large variation was found (expected to be due to microstructural variation) the average values for both methods of measurement is in good agreement in hydrogen. Following reduction in pure hydrogen, the fuel was changed to a mixture with high concentration of H2S. It was found that a concentration of 10 % H2S/H2 produced a sudden change in anode microstructure and resulted in loss of exchange current density. Lowering the amount of H2S in the initial fuel feed, which allowed for a more gradual microstructural change, allowed the cell to eventually function at concentrations in excess of 10 % H2S/H2. It was determined by OCV values in various concentrations of H2S/H2 that hydrogen is the predominant fuel of choice, even if H2S is available. Following electrochemical testing, slow cooling in a 10 % H2S/H2 mixture following produced metal sulfide spheres, as determined by SEM and EDS. Investigation in hydrocarbon, alcohol and biodiesel fuels was then undertaken to test the fuel variability of the given cermet anode material. Methane containing 10 % H2S was found to have increased exchange current density relative to poisoned hydrogen. Ethane and biodiesel experienced no increase in exchange current density, but a lengthening of the functional lifetime of the cell was observed, indicating reduced carbon poisoning. Methanol is a promising oxygen-containing SOFC fuel since it produced exchange current density values larger than hydrogen, and showed no evidence of coke formation by post-mortem SEM. Since oxygen-containing fuels are known to decompose in the gas phase at typical SOFC operating temperatures, the performance in a mixture of various CO/H2 fuels was then investigated. The Ni0.7Co0.3O-YSZ cermet anode gave higher exchange current density values for low ratio of CO/H2 fuels in the range 20/80 and 30/70 compared to pure H2. This is the first example of a Ni-based anode providing higher performance with a CO/H2 mixed fuel than for a pure H2 fuel. Finally, continuous running of a cell with fuel ratio 25/75 CO/H2 for 7 days produced exchange current density values, which were observed to increase significantly above the values for pure H2 during days 1-4 followed by deterioration below the value for hydrogen on subsequent days.

Abstract:
More than fifteen years after the introduction of direct election, the mayors are still the most popular politicians in Italy. The personal relationship set up with the citizens and the strengthening of the city councils has restored energy and stability to the action of the municipal administrations. Nevertheless, these institutional reforms, while important, have failed to guarantee good government. The effects of the mayoral reform are, in fact, considerably different from one city to another, and from one type of policy to another. What does this variety of results derive from? The book provides an answer to this question through an investigation of the decisional processes of around a hundred "local collective assets" in six large metropolitan cities. To explain the different outcomes – in addition to the "council effect", that is, the relevance of policy, and the "sector effect", the relevance of the different decisional milieus – the authors also underscore the role of the "governance effect", namely the different approaches to decision-making and building consensus on urban policies.

Abstract:
Continuum level mass and electronic transport through solid oxide fuel cell (SOFC) anodes are addressed employing the analytic solution of the Laplace equation. The constriction resistance effects of conventional interconnect design upon mass and electronic transport within SOFC anodes are emphasized. Mass transfer resistance effects are created by changes in cross-sectional area between the fuel stream-anode and anode-electrolyte interfaces. Similarly, increased ohmic losses are created by the reduction in cross-sectional area from the electrolyte-anode interface to the interconnect-anode interface. These resistance effects create competing losses that may require consideration in future SOFC component designs. The following paper has pilot quantification of such effects as an introduction to performance trends and an illustration of the analytic approach applied.

Abstract:
Wave and current loads on offshore structures are an important factor in the design of offshore structures. These forces are usually evaluated by semi-empirical Morison equation for tubular members wherein the ratio of characteristic dimension to wavelength is less than 0.2. In many cases, offshore structures such as jackets will have appurtenances such as anodes fitted on to them for various purposes, which may not contribute to the overall stiffness. However, these items will contribute to the wave and current loads in the order of magnitude of 10 to 20%. The calculation of hydrodynamic loads on such singular tubular members fitted with appurtenances can be done by taking to account their contribution towards drag and inertia. However, for complex structures, such as jacket structures with numerous members, it becomes practically very difficult and time consuming to do this calculation. In the industry, the general practice is to increase the overall loading due to presence of anodes by around 10 to 20%, based on experience and thumb rules. This paper focuses on the evaluation of wave loads on jackets due to the presence of anodes on jacket legs and braces, and comparing them to that of a jacket without anodes. The evaluation of wave loads is done by both numerical modelling and theoretical evaluation. The numerical model is based on frame analysis using SACS software which has the facility to simulate the wave load on space frame structures. Three different anode-to-jacket weight ratios (total weight of anode to total weight of jacket) are considered. The anodes are modelled as per design requirements and distributed throughout the structure. Recommended hydrodynamic coefficients from codal provisions are used. The overturning moments and base shear are evaluated for design regular waves and current. Results are presented in terms of comparison of base shear and overturning moment to ensure consistency, for three different cases. The recommendations for design engineers within the depth range and region studied can be drawn from this study.

Full text
Abstract:
Public expenditures on non-contributory pensions are equivalent to at least 1 percent of GDP in several countries in Latin America and is expected to increase. We explore the effect of non-contributory pensions on the well-being of the beneficiary population by studying the "Pensiones Alimentarias" program established by law in Paraguay, which targets older adults living in poverty. Households with a beneficiary increased their level of consumption by 44 percent. The program improved subjective well-being in 0.48 standard deviations. These effects are consistent with the findings of Bando, Galiani and Gertler (2020) and Galiani, Gertler and Bando (2016) in their studies on the non-contributory pension schemes in Peru and Mexico. Thus, we conclude that the effects of non-contributory pensions on well-being in Paraguay are comparable to those found for Peru and Mexico and add to the construction of external validity.

Full text
Abstract:
Specialized classes of concrete, such as ultra-high-performance concrete, use volumes of silica fume in concrete that are higher than those in conventional concrete, resulting in increased water demand and mixing difficulty. This study considered the effects of eight different silica fumes in three dosages (10%, 20%, 30%) with three w/b (0.20, 0.30, 0.45) on rheological behavior as characterized by the Herschel-Bulkley model. Results indicated that the specific source of silica fume used, in addition to dosage and w/b, had a significant effect on the rheological behavior. As such, all silica fumes cannot be treated as equivalent or be directly substituted one for another without modification of the mixture proportion. The rheology of cement pastes is significantly affected by the physical properties of silica fume more so than any chemical effects.

Full text
Abstract:
The literature that employs Regression Discontinuity Designs (RDD) typically stacks data across time periods and cutoff values. While practical, this procedure omits useful time heterogeneity. In this paper we decompose the RDD treatment effect into its weighted time-value parts. This analysis adds richness to the RDD estimand, where each time-specific component can be different and informative in a manner that is not expressed by the single cutoff or pooled regressions. To illustrate our methodology, we present two empirical examples: one using repeated cross-sectional data and another using time-series. Overall, we show a significant heterogeneity in both cutoff and time-specific effects. From a policy standpoint, this heterogeneity can pick up key differences in treatment across economically relevant episodes. Finally, we propose a new estimator that uses all observations from the original design and which captures the incremental effect of policy given a state variable. We show that this estimator is generally more precise compared to those that exclude observations exposed to other cutoffs or time periods. Our proposed framework is simple and easily replicable and can be applied to any RDD application that carries an explicitly traceable time dimension.
