Abstract:
A series of carbon nanotube (CNT)-supported amorphous Co–B alloy catalysts were prepared by selectively depositing Co–B particles inside and/or outside of CNTs. The effects of the nanotubular structure on the physiochemical properties of the amorphous Co–B alloys were studied. It was found that the internal loading enhanced the thermal stability of the amorphous Co–B alloys and inhibited the loss of Co compared with the external loading. The internal loading also increased the proportion of elemental Co in the Co–B alloys, while the loading method did not change the valence states of either Co or B. The internally loaded Co–B particles exhibited higher hydrogenation activity for m-chloronitrobenzene ( m-CNB) than the externally loaded analogue. The kinetics of m-CNB hydrogenation were also studied.

Abstract:
Haemophilus are fastidious Gram negative bacilli, which require factor X (hemin), factor V (NAD), or both for their growth. Haemophilus influenzae is the type species, and is considered to be the most pathogenic. They are associated with many invasive infections including meningitis, epiglottitis, pneumonia, and otitis media. Serotype b is most commonly associated with infections. Haemophilus species isolated from patients in a tertiary care centre in South India were studied. Identification, serotyping and biotyping were done and antibiotic susceptibility test was performed. The incidence of H. influenzae infections in our study was 65.3 cases/100,000 persons. Serotype b was the most common (66.67%), followed by non typeable H.influenzae (NTHi) (25%). Most isolates from adults were type b, while all isolates from pediatric population were non typeable. The most common biotype was type II, followed by type I and type III. Three of 24 isolates were β lactamase producers (12.5%). One isolate was β lactamase negative Ampicillin resistant (BLNAR). Resistance to ampicillin was 16.67%. Resistance to cephalosporins and fluoroquinolones was low (4-10%). Co-trimoxazole resistance was found to be very high (75%). All isolates were susceptible to azithromycin, tetracycline, chloramphenicol and meropenem. No isolates of H.influenzae type b were obtained from the paediatric population which may be due to the introduction of Hib vaccine. The increase in resistance to commonly used antibiotics is worrisome, especially penicillins and co-trimoxazole. Use of co-trimoxazole in empirical therapy of upper and lower respiratory tract infections has a high chance of failure in the current scenario.

Abstract:
The interactions between different genotypes of Hepatitis B virus (HBV) in co-infected patients remain largely unknown, especially in acute infection. Here, the evolution of HBV strains was studied in an acute, self-limited hepatitis B patient co-infected with genotypes Ba (B2) and C. Virological analyses were performed at four time points after admission: T1 (5 days), T2 (11 days), T3 (22 days) and T4 (260 days). A dominant-genotype change from genotype C to Ba was found after anti-HBV e antigen (anti-HBe) seroconversion. Further clonal and phylogenetic analyses of the pre-S and pre-core/core regions of HBV were carried out to clarify the interactions between genotypes Ba and C. All clones propagated from T1 and T2 were of genotype C. In contrast, clones propagated from T3 (after anti-HBe seroconversion) were of genotype Ba, C and/or recombinant within the pre-S region. At T4, all clones were of genotype Ba with a 123 bp (from nt 3147 of the pre-S1 region to nt 54 of the pre-S2 region) in-frame pre-S deletion and had lost the start codon of the middle envelope protein and the nucleocapsid-binding site. Phylogenetic analysis showed that genetic distance was greater at T3 after seroconversion to anti-HBe. By using SimPlot, the breakpoint of one pre-S recombinant was located at nt 3069–3100 and the other two at nt 49–87. In conclusion, HBV genotype Ba may overtake genotype C as the predominant strain after anti-HBe seroconversion in acute hepatitis B. Recombination within the pre-S region emerged transiently and the pre-S deletion mutant was finally cleared.

Abstract:
By using the first-principles methods based on density function theory (DFT), the effects of boron(B)/phosphorus(P) pair co-doping on the electrical properties of zigzag single-walled carbon nanotubes (SWNTs) have been investigated. We calculated the formation energies and band structures of (6, 0) metallic and (8, 0) semiconducting SWNTs with different B/P co-doping sites and concentrations. The obtained formation energies suggest that the B/P co-doping configurations are energetically stable structures and the B and P tend to form a B–P bond. It shows that an energy gap is opened by B/P co-doping in (6, 0) metallic SWNTs and the metallic carbon nanotubes are converted into semiconductors. For the (8, 0) semiconducting SWNTs, B/P co-doping influences the band structure, but it does not change the attributes essentially and the SWNTs are still semiconducting. It was also found that the band structures depend on the doping concentration as well as the doping site of B/P pair.

Abstract:
Most HIV positive people have not been tested for viral hepatitis and their treatments have not been optimized for possible co-infections. The aim of this study was to investigate the serological pattern of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among antiretroviral (ARV)-naive and -experienced HIV co-infected adults in Addis Ababa, Ethiopia. A total of 500 frozen HIV positive serum and plasma samples collected from ARV-naive (n = 250) and -experienced (n = 250) adults were randomly selected and screened for HBsAg, anti-HBs, HBeAg and anti-HCV using rapid two-site sandwich immunochromatographic assay. The test was performed at Aklilu Lemma Institute of Pathobiology, Addis Ababa University. Positive specimens for HBsAg and anti-HCV markers were further confirmed using third generation ELISA. Of the 500 specimens tested, 15 (3 %), 58 (11.6 %), 3 (0.6 %), 18 (3.6 %), 3 (0.6 %) and 1 (0.2 %) were positive for HBsAg, anti-HBs, HBeAg, anti-HCV, HBsAg and HBeAg, and HBsAg and anti-HBs markers, respectively. No specimen tested positive for both HBeAg and anti-HBs, and 442 (88.4 %) individuals were non-immune to HBV. Of the 250 ARV-naive individuals, 8 (3.2 %), 33 (13.2 %), 2 (0.8 %), 10 (4 %), 2 (0.8 %), and 1 (0.4 %) were positive for HBsAg, anti-HBs, HBeAg, anti-HCV, HBsAg and HBeAg, and HBsAg and anti-HBs markers, respectively. Of the 250 ARV-experienced individuals, 7 (2.8 %), 25 (10 %), 1 (0.4 %), 8 (3.2 %), 1 (0.4 %), and 0 (0 %) were positive for HBsAg, Anti-HBs, HBeAg, anti-HCV, HBsAg and HBeAg, and HBsAg and anti-HBs markers, respectively. In summary, seroprevalence of HIV/HBV and HIV/HCV co-infections was lower in Addis Ababa, Ethiopia, than in Sub-Saharan Africa and globally. HBV and HCV infections were not significantly different between HIV positive subjects who were or who were not on ARV. This suggests that the two groups have equal chance of being infected with these two viruses; despite this, disease progression could be different.

Abstract:
Doping impurity into ZnO is an effective and powerful technique to tailor structures and enhance its optical properties. In this work, Zn1−xMgxO and Zn1−x−yMgxByO nanoparticles (x = 0, 0.1, 0.2, 0.3, 0.4; y = 0, 0.02, 0.04) were synthesized via one-pot method. It shows that the Mg and B dopants has great influence on crystallinity and surface morphology of ZnO nanoparticles, without changing the wurtzite structure of ZnO. The band structure study indicates that the competition of Conductive Band (CB) shift, Burstein–Moss (B-M) shift and Shrinkage effect will cause the band gap energy change in ZnO.

Abstract:
Abstract Introduction CLL remains an incurable disease and represents a significant health problem in the western world. Increasing evidence highlights that the impact of marrow stromal cells is a key component influencing CLL B-cell survival. We have utilized an in vitro bone marrow stromal cell (BMSC) model system and found unique alterations in CLL B-cells with BMSC co-culture that point to previously unidentified biologic changes in the CLL B-cells that may influence CLL B-cell signaling and drug resistance. Methods Purified primary CLL B-cells (n= 39) from previously untreated CLL patients were cultured alone or co-cultured with primary BMSCs from either normal individuals (n=26) or CLL patients (n=17) at a 50:1 ratio in AIMV medium. After 48 hours, separated CLL B-cells or BMSCs were examined by immunoprecipitation/Western blot analyses and where needed real time PCR was done to assess the presence of intracellular proteins. In separate experiments to assess CLL B-cell killing, purified CLL B-cells were treated with TP-0903, fludarabine, chlorambucil and ibrutinib as single agents with or without BMSC co-culture. Results We observed significant increases in expression of Axl for both mRNA and protein levels in CLL B-cells co-cultured with BMSCs compared to CLL B-cells cultured alone. We also detected significantly increased expression of β-catenin at the protein level in CLL B-cells co-cultured with BMSC. But, we did not see any significant change in β-catenin or Axl protein expression in BMSCs co-cultured with CLL B-cells. Co-culturing of CLL B-cells with BMSCs using transwells confirmed that the upregulation of both Axl and β-catenin is dependent on the direct contact of CLL B-cells with BMSCs. The CLL B-cells from co-culture also had upregulation in phosphorylated (P)-ERK-1/2 but no change in P-AKT(Ser473). High nuclear β-catenin and P-ERK-1/2 levels were also detected in co-cultured CLL B-cells. ERK associates with and inactivates GSK-3β resulting in the up-regulation of β-catenin. We next checked for P-GSK-3β (Ser9) in co-cultured CLL B-cells. Upregulation in P-GSK-3β (Ser9) detected in co-cultured CLL B-cells suggests inactivation of GSK-3β and increasing β-catenin accumulation in co-cultured CLL B-cells. Moreover, inhibition of P-ERK-1/2 with inhibitor PD98059 in CLL B-cells cultured with BMSCs inhibited β-catenin as well as Axl expression levels. We also determined the phosphorylation status of Axl in CLL B-cells in co-culture with BMSC but found no change either at Y702 (Axl kinase domain) or total tyrosine phosphorylation levels for Axl in CLL B-cells. Thus, we assume that the role of Axl in co-cultured leukemic B-cells is independent of its kinase activity. Next we determined the effect of the highly specific Axl inhibitor TP-0903 on CLL B-cell status of Axl and b-catenin while in BMSC co-culture. Interestingly, both Axl and β-catenin protein expression levels were found to be further upregulated in CLL B-cells exposed to sub-lethal doses of TP-0903 in co-culture with BMSC. Treatment with chemotherapeutic or targeted therapy drugs, (i.e. fludarabine, chlorambucil or ibrutinib) also led to increase in expression levels of both β-catenin and Axl CLL B-cells co-cultured with BMSC. Of interest CLL B-cells were less sensitive to the chemotherapy drugs in presence of BMSCs, suggesting a role for both Axl and β-catenin in stromal mediated CLL B-cell drug resistance to these agents. This was not true for the Axl inhibitor as TP-0903 was able to induce robust cell death by targeting P-Axl and overcome BMSC mediated protection even in the presence of increased Axl and b-catenin. We also found that TP-0903 decreased P-Axl as well as the Axl downstream mediator, P-Akt(S473) and reduced Mcl-1 expression in CLL B-cells in BMSC co-culture. Conclusions Here we show that marrow stromal cell mediated increased expression in both β-catenin and Axl in CLL B-cells is associated with leukemic B cell survival and drug resistance. The mechanism for this may in part be via activated ERK levels that also occur when CLL B-cells contact BMSC. The BMSC resistance appears to be more profound for chemotherapeutic agents since Axl inhibitor can still induce CLL B-cell killing with BMSC co-culture. These studies suggest that a further understanding of the roles of Axl and β-catenin in the resistance status of CLL B-cells mediated by contact with BMSC are warranted.

Abstract:
Abstract. Understanding the mechanisms that transport pollutants from the surface to the free atmosphere is important for determining the atmosphere's chemical composition. This study quantifies the vertical transport of tropospheric carbon monoxide (CO) by deep mesoscale convective systems and assesses the ability of the satellite-borne Tropospheric Emission Spectrometer (TES) to detect the resulting enhanced CO in the upper atmosphere. A squall line that is similar to one occurring during NASA's INTEX-B mission is simulated using a typical environmental wind shear profile and the 2-D Goddard Cumulus Ensemble model. The simulation provides post-convection CO profiles. The structure of the simulated squall line is examined, and its vertical transport of CO is quantified. Then, TES' ability to resolve the convectively modified CO distribution is documented using a "clear-sky" retrieval scheme. Results show that the simulated squall line transports the greatest mass of CO in the upper levels, with a value of 96 t upward and 67 t downward at 300 hPa. Results indicate that TES has sufficient sensitivity to resolve convectively lofted CO, as long as the retrieval scene is cloud-free. TES swaths located immediately downwind of squall lines have the greatest chance of sensing convective transport because the impact of clouds on retrieval quality becomes less. A note of caution is to always analyze TES-derived CO data (or data from any satellite sensor) together with the retrieval averaging kernels that describe the information content of the retrieval.

Abstract:
Nanokristalline Permanentmagnete zeigen ungewöhnliche magnetische Eigenschaften aufgrund von Oberflächen- und Grenzflächeneffekten, die verschieden von denen massiver oder mikrokristalliner Materialien sind. Diese Arbeit zeigt Ergebnisse einer systematischen Untersuchung der Beziehung zwischen Mikrostruktur und magnetischen Eigenschaften von isotropen nanokristallinen (Nd,Pr)(Fe,Co)B-Permanentmagneten. Hochkoerzitive Magnete vom Typ (Nd,Pr)FeB wurden durch hochenergetisches Mahlen in der Kugelmühle oder Rascherstarrung hergestellt. Der Einfluss geringer Mengen von Zusätzen wie Dy und Zr und die Substitution von Nd durch Pr auf die magnetischen Eigenschaften wird dargestellt. Weiterhin wurde eine Einschätzung des Warmumformverhaltens dieser Materialien durchgeführt. Hochenergetisches Kugelmahlen einer Legierung mit der Anfangszusammensetzung Pr9Nd3Dy1Fe72Co8B6.9Zr0.1 führte, nach Glühbehandlung, zu fast einphasigem Magnetpulver mit einem maximalen Energieprodukt von (BH)max~140 kJm-3. Das hochenergetische Kugelmahlen wurde zu einer sehr vielseitigen Technik zur Herstellung hochleistungsfähiger Nanokompositmagnete weiterentwickelt. Das Zulegieren unterschiedlicher Anteile von weichmagnetischem alpha-Fe ist damit sehr effektiv möglich. Der Zusatz von 25 Gew.-% alpha-Fe führt zu einem hohen (BH)max=178kJm-3. Dies wird auf eine sehr effektive Austauschkopplung zwischen den hart- und weichmagnetischen Phasen zurückgeführt. Die Natur der intergranularen Wechselwirkungen kann durch die Wohlfarth´sche Remanenzanalyse (?deltaJ-plot¡§) beschrieben werden. Im speziellen wurden deltaJ-Diagramme für verschiedene (i) alpha-Fe Gehalte, (ii) Korngrößen und (iii) Austauschlängen erstellt. Es konnte gezeigt werden, dass in den Nanokompositmagneten auf Pr-Basis keine Spinumorientierung auftritt. Abschließend zeigt die Arbeit die Möglichkeit der Nutzung einer mechanisch aktivierten Gas-Festkörper-Reaktion auf, mit der eine sehr feinkörnige Mikrostruktur erhalten wird. Die Untersuchungen wurden mit stöchiometrischen Nd2(Fe1-xCox)14B-Legierungen begonnen (x=0-1). Die Verbindungen wurden unter höheren Wasserstoffdrücken und Temperaturen gemahlen, wodurch sie zu NdH2+delta und krz-(Fe,Co) (x=0-0.75) oder kfz-Co (x=1) entmischt wurden. Die Korngrößen des rekombinierten Nd2(Co,Fe)14B-Materials liegen im Bereich von 40-50 nm
Nanocrystalline permanent magnets present unusual magnetic properties because of surface/interface effects different from those of bulk or microcrystalline materials. This work presents results of a systematic investigation of the relationship between microstructure and magnetic properties in isotropic nanocrystalline (Nd,Pr)(Fe,Co)B permanent magnets. Highly coercive (Nd,Pr)FeB-type magnets have been produced using high energy ball milling and melt-spinning. The influence of small amounts of additives, Dy and Zr, and the substitution of Nd by Pr on the microstructural and magnetic properties are shown. An assessment of the hot deformation behaviour has been carried out. Intensive milling of an alloy with starting composition Pr9Nd3Dy1Fe72Co8B6.9Zr0.1 yields, after annealing treatment, nearly single-phase magnet powders with a maximum energy product (BH)max?î140kJm-3. Co has a beneficial effect on the intrinsic magnetic properties but also on the microstructure, with a mean grain size of 20nm. Intensive milling is used to produce high-performance nanocomposite magnets by blending this latter alloy with different fractions of soft magnetic alfa-Fe. Addition of 25wt.% alfa-Fe leads to a high (BH)max=178 kJm-3 due to an effective exchange-coupling between the hard and the soft magnetic phases. The intergrain interactions between the crystallites of the nanocomposite structure are analysed. Demagnetisation recoil loops of the nanocomposite magnets show relatively open minor loops due to the exchange-spring mechanism. Information about the intergrain interactions during demagnetisation are obtained by plotting the deviation of the demagnetising remanence from the Wohlfarth-model (¡§deltaJ-plot¡¨). Exchange-coupling phenomena are studied by analysing the evolution of the corresponding deltaJ values when varying (i) the alfa-Fe content, (ii) the annealing temperature, i.e. the grain size and (iii) the measurement temperature. Low temperature measurements do not reveal any sign of spin reorientation for these Pr-based nanocomposite magnets. The work concludes showing the possibility of using a mechanically activated gas-solid reaction to obtain an effective grain refined microstructure starting from stoichiometric Nd2(Fe1-xCox)14B alloys (x=0-1). These compounds were milled under enhanced hydrogen pressure and temperature leading to their disproportionation into NdH2+delta and bcc-(Fe,Co) (x=0-0.75) or fcc-Co (x=1). Grain sizes of recombined Nd2(Fe,Co)14B materials were found to be 40-50nm

Abstract:
Individuals with HIV-HBV coinfection are at risk of accelerated hepatic fibrosis, and end stage liver disease is now a major cause of morbidity and mortality in this population. For many years lamivudine (3TC) monotherapy was the only effective treatment for HBV in coinfected individuals, but its use was complicated by the frequent development of HBV drug resistance, and loss of virological suppression. With the availability of new potent antivirals for HBV, including tenofovir (TDF), therapeutic options for HIV-HBV coinfected individuals have increased, although the management of HBV disease in this population is still often suboptimal. This thesis explores through a series of published papers, issues in the current management of HIV-HBV coinfected individuals_ Chapter 1 describes a high incidence of 3TC resistance in HIV-HBV individuals on extended 3TC monotherapy, and in particular, a significant proportion with complex HBV-drug resistant mutants, with potential public health implications. In Chapter 2 the benefits of TDF ???induced virological suppression on parameters of end stage liver disease are described. Chapters 3 and 6 explore the role of TDF as monotherapy, or in combination with 3TC, within HBV-active antiretroviral therapy (ARn. No benefit for TDFj3TC combination versus TDF monotherapy is observed in treatment naive individuals; although a potential benefit for combination therapy is observed in treatment experienced subjects. In Chapter 4 a high rate of hepatic flare (HF) after initiation of HBV-active ART is described, and potential predictors of flare including elevated baseline ALT and HBV DNA are identified to suggest HBV immune restoration disease (IRD) as the major underlying cause of HF in this study. Chapter 5 discusses the immunopathogenesis of HBV IRD in more detail and proposes guidelines for clinical management. In summary the thesis finds that the therapeutic outlook for HIV-HBV coinfected individuals is generally optimistic, although several further research areas are identified, particularly in middle and low- income settings where the burden of HIV and HBV disease is greatest.

Abstract:
Biomaterials based on block segmented copolymers constituted by hard and soft segments have attracted much attention for biomedical applications in the last decades, specifically as absorbable monofilament sutures. Polyglycolide has demonstrated to be a good candidate to constitute the hard segment due to its biodegradability and high stiffness, whereas the incorporation of different monomers (e.g. -caprolactone, trimethylene carbonate or glycolide) in a random distribution as soft segment promotes material flexibility and enhances in vitro degradation rates. Resulting material properties can be tailored by the combination of different ratios of hard and soft segments and the specific monomer composition. In this Thesis the study of a tricomponent segmented copolymer commercially marketed as Monosyn® by B. Braun Surgical as an absorbable monofilament suture is presented. The main goals of the work concern to: a) the complete physical characterization that involves the study of the crystallization kinetics and thermal stability, b) the study of the degradation behavior and the associated microstructural changes, c) the evaluation of the capability to improve the performance of Monosyn® by adding compounds with pharmacological activity and d) the production of nanofibers to be employed as reinforcing agents. Isothermal and non-isothermal crystallizations were followed by different techniques (e.g. optical microscopy, differential scanning calorimetry and time-resolved SAXS experiments in a synchrotron radiation facility). The composition of the soft segment influenced in the crystallization of the segmented copolymer as could be deduced by comparison with reported data on similar bicomponent systems. Hydrolytic degradation was carried out at different temperatures and in buffered media of a continuous range of pH. Surface morphology of hydrolyzed sutures showed the formation of longitudinal and circumferential cracks in the outer and inner part of the suture, respectively. These fractures were associated to the existence of interfibrillar and interlamellar amorphous domains as was revealed by SAXS experiments. To explore the potential applications of Monosyn® as an absorbable monofilament suture with pharmacological activity, different drugs were incorporated. Moreover, the use of an amorphous copolymer coating was also evaluated. The first group of drugs selected were biguanide compounds (i.e. chlorhexidine and polyhexametilen biguanide), which have a well-recognized bactericide activity. Specifically, the effectiveness of using a coating was proved as well as the influence of drug molecular size in the activity. The study of the loading process, release behavior and pharmacological activity was completed considering an antibiotic (chloramphenicol) and a healing agent (captopril). Finally, nanofibers of the selected copolymer were prepared by means of the electrospinning technique. These nanofibers were also loaded with pharmacological drugs and used as reinforcing agent of biodegradable polymer matrices. In order to obtain appropriate fabrics different fiber compositions and electrospun set up configurations were tested.
En las últimas décadas, los biomateriales basados en copolímeros segmentados, constituidos por segmentos duros y blandos, han atraído el un creciente interés para una amplia gama de s aplicaciones biomédicas, especialmente como suturas monofilares absorbibles. Se ha demostrado que la poliglicolida es una buena candidata para constituir el segmento duro debido a su biodegradabilidad y a su alta rigidez, mientras que la incorporación de distintos monómeros (por ejemplo, -caprolactona, carbonato de trimetileno o glicolida) en una disposición estadística como segmento blando promueven la flexibilidad del material y mejoran la velocidad de degradación in vitro. Las propiedades de los materiales resultantes pueden ajustarse combinando diferentes proporciones de los segmentos duro y blando, y con una composición específica de monómero. En esta Tesis se presenta el estudio del copolímero segmentado tricomponente comercializado por B.Braun Surgical como sutura absorbible monofilar con el nombre de Monosyn®. Los principales objetivos de este trabajo son: a) la caracterización física completa que incluye el estudio de estabilidad térmica y cinéticas de cristalización, b) el estudio de la degradación y los cambios microestructurales asociados, c) la evaluación de la mejora del uso de la sutura añadiendo componentes con actividad farmacológica, y d) la producción de nanofibras para utilizarlas como agentes reforzantes. Las cristalizaciones isotérmicas y no isotérmicas se siguieron mediante distintas técnicas (microscopía óptica, calorimetría diferencial de barrido y experimentos de difracción de rayos X de bajo ángulo). La composición del segmento blando influyó en la cristalización del copolímero segmentado, como era de esperar por la comparación con los datos publicados del sistema bicomponente similar. La degradación hidrolítica fue llevada a cabo a distintas temperaturas con disoluciones tamponadas en un rango continuo de pH. La morfología de la superficie de las suturas hidrolizadas mostró la formación de fracturas longitudinales y circunferenciales en la zona externa e interna de la sutura, respectivamente. Estas fracturas se asociaron a la existencia de dominios amorfos interfibrilares e interlamelares, tal y como se corroboró mediante los experimentos de difracción de rayos X de bajo ángulo. Para explorar las aplicaciones potenciales de Monosyn® como sutura absorbible monofilar con actividad farmacológica, se incorporaron distintos fármacos. Además, se evaluó el uso de un copolímero amorfo como recubrimiento. El primer grupo de fármacos seleccionados corresponden a la familia de las biguanidas (clorhexidina y polihexametilen biguanida), conocidas por su actividad bactericida. En particular se probó la efectividad de utilizar un recubrimiento y la influencia del tamaño molecular del fármaco en su actividad. El estudio del proceso de carga, el perfil de liberación y la actividad farmacológica se completó considerando también un antibiótico (cloranfenicol) y un agente cicatrizante (captopril). Por último, se prepararon nanofibras del copolímero seleccionado mediante la técnica del electrohilado. Estas nanofibras se cargaron con fármaco y se utilizaron como agentes reforzantes de matrices poliméricas biodegradables. Con el propósito de conseguir unos tejidos apropiados, se probaron distintas composiciones de fibras y diferentes configuraciones en el montaje del sistema de electrohilado.

Abstract:
Au vu du contexte actuel (mondialisation des échanges, concurrence, innovations technologiques…), les entreprises doivent trouver les moyens de proposer des produits et services toujours plus innovants pour se différencier. C’est pourquoi, elles font de plus en plus appel aux compétences des clients pour concevoir leurs offres qui correspondront davantage à leurs besoins. Cette pratique qui suscite un réel engouement auprès des managers est appelée « co-création ».Or, d’après la littérature, il semblerait que peu de recherches ne se sont intéressées aux raisons pour lesquelles certaines entreprises sont plus prédisposées que d’autres à co-créer des services dans le contexte interorganisationnel (Business-to Business, B to B). Pourtant, cette question est fondamentale. En effet, s’il est démontré que certains facteurs favorisent l’adhésion des clients et la gestion de projets de co-création, les organisations pourront mieux choisir des partenaires (candidats) à un projet de co-création. Ainsi, notre travail de recherche propose de répondre à la question suivante : Pourquoi certaines entreprises sont-elles plus disposées à co-créer un service alors que d’autres le sont moins ?Dès lors, après avoir réalisé un état de l’art sur la co-création de services, nous menons deux études qualitatives auprès de dirigeants et de clients B to B impliqués dans des démarches de co-création de services innovants. La troisième étude de nature quantitative est réalisée auprès d’un échantillon de prestataires de services destinés aux entreprises afin de tester nos hypothèses de recherche. Les résultats obtenus ont permis d’identifier des critères à la fois organisationnels (spécifiques à l’entreprise) et sectoriels (c’est-à-dire, relatifs au marché) explicatifs de la prédisposition et du degré d’implication des entreprises dans un processus de co-création. D’un point de vu managérial, cette recherche souligne les bonnes pratiques à mettre en place au sein des organisations avant d’initier cette démarche collaborative
In the current world context (globalization, competition, technological innovations,.), companies must look for new ways to offer more innovative goods and services. Therefore, they require customer’s competencies to design offerings that meet their needs. This practice which is raising a great deal of enthusiasm from the managers is called “co-creation”.An examination of the existing literature on services suggests that little has been done on the reasons why some companies are more disposed to engage in a B to B service co-creation process while others are less disposed to do so. Yet, this is an important issue. Indeed, if we can show that there are some criteria which can be used to identify potential co-creators and that facilitate the management of co-creation projects, then organizations could use this knowledge to select their partners in a co-creation process.In the light of the foregoing, our research study seeks to answer the following question: Why are some B-to-B service providers more disposed to co-create services than others?After a literature review on service co-creation, we conduct two qualitative studies with leaders and B to B customers involved in innovative service co-creation projects. The third study that is quantitative surveys a number of service providers in order to test our research hypothesis.Our empirical results allow us to identify firm-level and industry-level criteria relevant for explaining businesses’ willingness to engage in a co-creation process as well as their level of involvement in this process. From a managerial perspective, the present research also underlines the best practices to implement in service organizations before starting such a collaborative approach

Abstract:
Nous nous sommes attaché à étudier les liens entre propriétés cristallographiques et magnétiques de phases intermétalliques R M-B où R est un élément de terres rares, l'yttrium ou le thorium et M un métal de transition 3d. La présence de bore dans l'environnement atomique des sites de métaux de transition, notamment, agit fortement sur les propriétés magnétiques tant à l'échelle macroscopique que microscopique.
Nous apportons une contribution à l'étude des propriétés magnétiques particulières du composé YCo4B, composé modèle et de référence de la famille Rn+mCo3n+5mB2n. L'anisotropie magnétocristalline originale de ce composé est caractérisée à la fois par une réorientation de spin et un processus d'aimantation du premier ordre. Elle s'avère également fort sensible à la pression comme l'ont montré nos mesures magnétiques. La substitution du fer au cobalt dans les composés RCo4B est possible et donne lieu à un schéma préférentiel comme l'illustre nos mesures de diffraction des neutrons. En combinant ces résultats à des mesures magnétiques diverses et de spectroscopie Mössbauer, les propriétés magnétiques de chaque site cristallographique de métaux de transition 3d ont pu être particularisées.
Nous avons étudié la solution solide Y1-xThxCo4B et montré l'existence d'une substitution préférentielle du thorium à l'yttrium sur un site cristallographique. Ces deux éléments R non magnétiques ont des effets différents sur les propriétés magnétique des composés. Par comparaison à des études magnétiques sous pression, il a été possible de montrer que ces différences sont principalement dues aux différences de configuration électronique entre le thorium et l'yttrium et peu aux évolutions structurales induites par la substitution.
De nouveaux composés de la famille structurale Rn+mCo3n+5mB2n ont été mis à jour récemment. Nous présentons des études des conditions de synthèses et des structures magnétiques de quelques phases R3Co13B2 et R5Co19B6. Le composé Pr5Co19B6 présente notamment des anomalies magnétiques interprétables comme une réorientation de spin à basse température.
Nous présentons des résultats d'absorption des rayons X réalisés sur plusieurs compositions de la solution solide CeCo12-xFexB6. Dans cette structure, le cérium présente un état de valence intermédiaire qui évolue notablement en fonction de la teneur en fer.
Enfin, nous avons précisé les conditions de synthèse de phases métastables Nd2Fe23B3 et Y3Fe62B14, très riches en fer. Ces structures originales présentent de nombreux types d'environnements atomiques du fer ce qui en fait des composés aux propriétés magnétiques intéressantes. Nous avons notamment montré les évolutions inhabituelles de ces propriétés magnétiques entre les états amorphe et cristallisé de ces alliages.

Abstract:
Dans le cadre du présent travail, une étude approfondie a été menée sur les alliages Co-B en termes d'évolution de la microstructure lors d'une solidification hors équilibre avec ou sans champ magnétique ainsi que sur une transition liquide-liquide induite par la température.Un alliage hypereutectique Co-20at.%B a été sous-refroidi par la technique de l'encapsulation vitreuse. Une transition de l'hypereutectique à l'hypoeutectique a été trouvée à un sous-refroidissement critique de ∆T=119 K. Quand ∆T<119 K, une phase dendritique directionnelle primaire β-Co3B entourée par l'eutectique lamellaire régulière de α-Co+β-Co3B a été observée. Lorsque ∆T>119 K, la microstructure hypereutectique ci-dessus se transforme en structure hypoeutectique avec la phase α-Co comme phase primaire. Selon le modèle de croissance de la dendrite, le passage de l'hypereutectique à l'hypoeutectique peut être attribué à la vitesse de croissance plus élevée de la α-Co que de la β-Co3B, c'est-à-dire un mécanisme contrôlé par la croissance.La surchauffe et le refroidissement cycliques ont été effectués pour les alliages hypereutectiques sous-refroidis Co-20at.%B, eutectiques Co-18.5at.%B et hypoeutectiques Co-17at.%B. Pour chaque alliage, il y a une température critique de surchauffe Tc0 à laquelle il y a une brutale augmentation du sous-refroidissement moyen. Les mesures DSC montrent qu'il y a un pic d'absorption thermique dans le processus de chauffage, dont le pic de température est presque égal à la température critique de surchauffe, ce qui indique qu'une transition structurale liquide-liquide induite par la température se produit et doit être étroitement liée à la nucléation dans le liquide eutectique Co-B sous refroidi. L'effet de la transition structurale liquide-liquide sur la nucléation a été interprété par la récente théorie de la nucléation qui considère les structures des liquides en fusion surchauffées, et la température de surchauffe critique TcO, dépendante de la composition, a été attribuée au changement de structures préférentielles locales.Grace à une mesure in situ de l'aimantation, la transition structurale liquide-liquide induite par la température a été étudiée plus en profondeur. Une anomalie d'aimantation en terme de non dépendance de l'aimantation selon une loi de Curie-Weiss a été observée à l'état surchauffé, ce qui démontre une transition structurale liquide-liquide induite par la température. Ce comportement anormal s'est avéré être une règle universelle pour le système d'alliage binaire Co-B. Une température de transition (T0) et deux températures de Curie paramagnétiques (θ(LI), θ(LII)) correspondant à deux structures différentes des liquides sont déterminées. Les effets de l'intensité du champ magnétique sur la transition liquide-liquide et les températures de Curie paramagnétiques sont étudiés. T0 et θ(LII) ne sont pas sensibles à l'intensité du champ, tandis que θ(LI) passe à des températures plus basses avec une intensité croissante du champ magnétique. Avec une concentration croissante de Cobalt, T0, θ(LI) et θ(LII) passent à des températures plus élevées et les constantes de Curie pour le liquide I et le liquide II diminuent.Sous l'effet d'un champ magnétique imposé, un alignement morphologique a été trouvé pour la phase primaire α-Co avec son tronc primaire de dendrite ou son grand axe parallèle à la direction du champ magnétique. Les phases primaires de α-Co sont de formes cylindriques ou sphériques avec un sous-refroidissement relativement élevé, et l'application d'un champ magnétique est plus propice à l'obtention de ce type de phases α-Co. L'énergie magnétique, le couple magnétique et le temps requis pour la rotation ont été analysés théoriquement pour évaluer l'alignement magnétique et les mécanismes d'alignement. Les forces dipolaires entre les particules ont été calculées sur la base desquelles le phénomène d'auto-organisation des particules primaires de α-Co sous forme d'empilement en chaîne a été décrit
In the present work, a thorough investigation has been conducted on the Co-B alloys in terms of the microstructure evolution during non-equilibrium solidification with/without magnetic field and temperature induced liquid-liquid structure transition.A Co-20at.%B hypereutectic alloys was undercooled by the melt fluxing technique. A transition from hypereutectic to hypoeutectic was found at a critical undercooling of ∆T=119 K. When ∆T<119 K, a primary directional dendritic β-Co3B phase surrounded by the regular of α-Co+β-Co3B lamellar eutectics was found. When ∆T>119 K, the above hypereutectic microstructure changes into hypoeutectic structure with the α-Co phase as the primary phase. According to dendrite growth model, the transition from hypereutectic to hypoeutectic can be ascribed to the higher growth velocity of the α-Co phase than the β-Co3B phase, i.e., the growth-controlled mechanism.Cyclic superheating and cooling were carried out for the undercooled hypereutectic Co-20at.%B, eutectic Co-18.5at.%B and hypoeutectic Co-17at.%B alloys. For each alloy, there is a critical overheating temperature Tc0 at which there is a sharp increase of the mean undercooling. DSC measurements show that there is a thermal absorption peak in the heating process, the peak temperature of which is nearly equal to the critical overheating temperature, indicating that the temperature induced liquid-liquid structure transition does occur and should relate highly to nucleation in the undercooled Co-B eutectic melts. The effect of the liquid-liquid structure transition on nucleation was interpreted by the recent nucleation theory that considers the structures of overheated melts, and the composition-dependent overheating temperature was ascribed to the change of local favored structures.By in situ measuring the magnetization, the temperature induced liquid-liquid structure transition was further investigated. A magnetization anomaly in term of the non-Curie-Weiss temperature dependence of magnetization was observed in the overheated state, demonstrating a temperature induced liquid-liquid structure transition. This anomalous behavior was found to be a universal formula for the Co-B binary alloy system. A transition point (T0), two different Curie constants and two paramagnetic Curie temperatures (θ(LI), θ(LII)) corresponding to two distinct kinds of liquids (i.e., high-magnetization liquid I and low-magnetization liquid II) are determined. The Curie constant of liquid II was found much higher, which is attributed to the survived covalent bond below T0. The effects of magnetic field intensity on the liquid-liquid structure transition and paramagnetic Curie temperatures are studied. T0 and θ(LII) are found not sensitive to the field intensity, whereas, θ(LI) shifts to lower temperatures with the increasing magnetic field intensity. With the increased concentration of Co, T0, θ(LI) and θ(LII) shift to higher temperatures and the Curie constants for the liquid I and liquid II decrease. Based on the location of T0, a guideline was drawn above the liquidus in the Co-B phase diagram, which could provide a significant guidance to the practical melt treatment.Under an imposed magnetic field, a morphological alignment was found for the primary α-Co phase with its primary dendrite trunk or long axis paralleling to the direction of magnetic field. The primary α-Co phases are rod-like or spherical at relatively high undercooling, and the application of magnetic field is more conducive to obtain such kind of α-Co phases. The magnetic energy, magnetic torque and time required for rotation were analyzed theoretically to evaluate the magnetic alignment and alignment mechanisms. The dipolar forces between particles were calculated, based on which the phenomenon that the primary α-Co particles self-organize as chain-like stacking was described

Abstract:
Digital Mock-up (DMU) is a widely introduced technology to virtually investigate geometrical and mechanical product properties. Functional Digital Mock-up (FunctionalDMU) is a combination of traditional DMU with behavioral simulation in mechatronics. Enhancing DMU with functional aspects, considerably more insight in product properties can be gained. To enable FunctionalDMU two main tasks have to be solved: a) simulators in the areas of mechanics, electronics, and software simulation have to talk to each other (coupling) and b) the simulation results have to be visualized in an interactive DMU environment. In this paper we present an independent and open approach to a FunctionalDMU framework including co-simulation. Starting with proprietary and natively given behavior and geometric models (in formats like JT), we wrap the behavior models into SysML to enable data exchange on an agreed and standardized format. The native behavior models still are executed in the corresponding simulators. The simulators are linked to the FunctionalDMU framework using a wrapping approach. Currently we support simulators such as Matlab/Simulink, Dymola, Saber, Rhapsody, SimPack, ANSYS with our framework. During simulation a simulator coupling algorithm controls the simulation processes. A dedicated visualization environment enables the user to interact with the simulation, i.e., to send simulation stimuli, change parameters, observe the simulation run etc. This paper introduces the components of the FunctionalDMU framework and illustrates the approach with an application example.

Abstract:
The ASTM standard B 575 provides the requirements for the chemical composition of Nickel-Chromium-Molybdenum (Ni-Cr-Mo) alloys such as Alloy 22 (N06022) and Alloy 686 (N06686). The compositions of each element are given in a range. For example, the content of Mo is specified from 12.5 to 14.5 weight percent for Alloy 22 and from 15.0 to 17.0 weight percent for Alloy 686. It was important to determine how the corrosion rate of welded plates of Alloy 22 using Alloy 686 weld filler metal would change if heats of these alloys were prepared using several variations in the composition of the elements even though still in the range specified in B 575. All the material used in this report were especially prepared at Allegheny Ludlum Co. Seven heats of plate were welded with seven heats of wire. Immersion corrosion tests were conducted in a boiling solution of sulfuric acid plus ferric sulfate (ASTM G 28 A) using both as-welded (ASW) coupons and solution heat-treated (SHT) coupons. Results show that the corrosion rate was not affected by the chemistry of the materials within the range of the standards.

Abstract:
The ASTM standard B 575 provides the requirements for the chemical composition of Nickel-Chromium-Molybdenum (Ni-Cr-Mo) alloys such as Alloy 22 (N06022) and Alloy 686 (N06686). The compositions of each element are given in a range. For example, the content of Mo is specified from 12.5 to 14.5 weight percent for Alloy 22 and from 15.0 to 17.0 weight percent for Alloy 686. It was important to determine how the corrosion rate of welded plates of Alloy 22 using Alloy 686 weld filler metal would change if heats of these alloys were prepared using several variations in the composition of the elements even though still in the range specified in B 575. All the material used in this report were especially prepared at Allegheny Ludlum Co. Seven heats of plate were welded with seven heats of wire. Immersion corrosion tests were conducted in a boiling solution of sulfuric acid plus ferric sulfate (ASTM G 28 A) using both as-welded (ASW) coupons and solution heat-treated (SHT) coupons. Results show that the corrosion rate was not affected by the chemistry of the materials in the range of the standards.

Abstract:
The present study has experimentally investigated the effect of fuel gas composition on the combustion, emission and knocking characteristics of a marine lean burn gas engine. The experiments was carried out using the lean burn gas engine, which has the rated power output of 400 kW with spark ignition pre-chamber system. The various compositions of the base fuel gas (Japanese city gas) changed by supplying propane-based LPG (liquefied petroleum gas), butane-based LPG and hydrogen. This paper reports in detail the experimental results on the combustion and emission characteristics of the lean burn gas engine affected by the fuel gas composition. The experimental results showed that the composition of fuel gas mixed with P-LPG and B-LPG has a small effect on the combustion characteristics, and the operation of the engine is hardly affected. However, the addition of hydrogen causes the rise of the maximum combustion pressure and the attention should be paid on the ratio of hydrogen in the fuel gas. With regard to the emission characteristics, the NOx emission increased with increasing the ratio of P-LPG, B-LPG and hydrogen in the base fuel gas. The CO emission increased with increasing the ratio of P-LPG and B-LPG and decreased with increasing the ratio of hydrogen in the base fuel gas. It is expected that such the tendencies depended on the carbon quantity in the fuel gas. In addition, it was found that the knocking characteristics are associated with the methane number of fuel gas.

Abstract:
Abstract The present goal of combustion research is to enhance the burning efficiency resulting in minimal emission which is in fact, paves the way for a sustainable future. Researchers are investigating different parameters and factors associated with combustion to control the combustion process. Image processing is one of the most useful and safe tool for this job as it is nonintrusive and do not interfere with the combustion zone during experiment. Present work focuses on the digital image processing of the premixed and diffusion flame which has been utilized as a tool to characterize burner stabilized premixed and non-premixed Flame. The experiment is performed on a burner stabilized LPG-air flame. For premixed flame, several sets of experiments are done keeping the camera setting and image quality identical which resulted in an almost linearly increasing average RGB value with respect to equivalence ratio. Taking the relation of an experiment as standard, equivalence ratio is calculated for other experiments just by observing the average RGB value(R+G+B/3) of that image. It is found that almost in all cases the error values are lying between −10% to +10% of the actual value calculated from the flow rates of air and fuel. Diffusion flame is examined by passing fuel through the central channel of co-flow burner and air through the outer cylindrical channel. Air is used to stabilize the flame and for giving it a steady shape. Experiment is done keeping air flow constant while the fuel flow is varied and the image is captured. For diffusion flame, as the change in colour of flame is not much differentiable with the change in fuel, analysis is done to find the relation between fuel flow rate and flame area by counting the number of pixels. Finally, a direct relation of fuel amount and the image area is obtained.
