Abstract:
In many heterogeneous catalytic reactions, such as low-temperature CO oxidation, the preparation conditions, and the role of the CeO2 support (oxygen vacancies and redox properties) in the dispersion and the chemical state of Au, are considered critical factors for obtaining gold nanoparticle catalysts with high catalytic performance. In this work, the physical and chemical preparation methods were compared, aiming at understanding how the preparation method influences the catalytic activity. The Au/CeO2 nanoparticle catalysts with 5% Au loading were prepared via the Physical Laser Vaporization Controlled Condensation method (LVCC), and the chemical Deposition-Precipitation method (DP) was used to investigate the effect of synthesis methods on the structure and the catalytic activity toward the CO oxidation. In this manuscript, we compare the activity of nanostructured Au/CeO2 catalysts. The structure and the redox properties of the catalysts were investigated by the XRD, SEM, TEM, TPR, and XPS. The catalytic activity for low-temperature CO oxidation was studied using a custom-built quartz tube flow reactor coupled with an infrared detector system at atmospheric pressure. The study reveals that the prepared CeO2-supported Au nanoparticles’ catalytic activity was highly dependent on the preparation methods. It showed that the sample prepared by the DP method exhibits higher catalytic efficiency toward CO oxidation when compared with the sample prepared by the LVCC method. The high catalytic activity could be attributed to the small particle size and shape, slightly higher Au concentration at the surface, surface-active Au species such as Au1+, along with the large interface between Au and CeO2. This study suggests that the stability, dispersion of Au nanoparticles on CeO2, and strong interaction between Au and CeO2 lead to strong oxidation ability even below room temperature. Considering the universal character of different physical and chemical methods for Au/CeO2 preparation, this study may also provide a base for supported Au-based catalysts for many oxidation reactions in energy and environmental applications.

Abstract:
Light verb constructions (LVCs) in English and Romance languages are somewhat unique crosslinguistically because LVCs in these languages tend to have semantically similar synthetic verb counterparts (Zarco 1999): e.g. make an appearance and appear. This runs contrary to assumptions in linguistic theories that two competing forms are rarely maintained in a language unless they serve distinct purposes (e.g. Grice 1975). Why do English LVCs exist alongside counterpart synthetic verbs, especially given that synthetic verbs are arguably the more efficient form (Zipf 1949)? It has been proposed that LVCs serve an aspectual function (Prince 1972, Live 1973, Wierzbicka 1982, Tanabe 1999, Butt & Geuder 2001), as there are telic LVC counterparts (e.g. have a thought) of atelic verbs (e.g. think). This proposal has been difficult to evaluate without a large-scale resource providing a markup of both LVCs and counterpart verbs. Addressing this gap in resources, the present research describes the development of guidelines for LVC annotation in the English PropBank (Bonial & Palmer 2015). The focus of this article is the subsequent analysis of these annotations, aimed at uncovering corpus evidence of what contexts call for the use of an LVC over a synthetic verb. The corpus study shows that the general function of LVCs is not an aspectual one and provides distributional evidence that the ease and variety with which LVCs can be modified is the general motivating factor for the use of an LVC.

Abstract:
In this paper, we present several examples of the vapor-phase synthesis of intermetallic and alloy nanoparticles and nanowires, and investigate their magnetic and catalytic properties. In the first example, we report the vapor-phase synthesis of intermetallic aluminide nanoparticles. Specifically, FeAl and NiAl nanoparticles were synthesized via laser vaporization controlled condensation (LVCC) from their bulk powders. The NiAl nanoparticles were found to be paramagnetic at room temperature, with a blocking temperature of approximately 15 K. The FeAl nanoparticles displayed room-temperature ferromagnetism. In the second example, we report the vapor-phase synthesis of cobalt oxide nanoparticle catalysts for low-temperature CO oxidation. The incorporation of Au and Pd nanoparticles into the cobalt oxide support leads to significantly improved catalytic activity and stability of the binary catalyst systems. Finally, we report the synthesis of nanowires of Ge, Mg, Pd, and Pt using the vapor-liquid-solid (VLS) method where the vapor-phase growth of the wire is catalyzed using a proper metal catalyst present in the liquid phase.

Abstract:
Abstract This study investigated nativised structural patterns of light verb constructions (LVCs) in Malaysian English using a corpus-based, descriptive approach to analyse grammatical innovations. To facilitate the analysis, a 100-million-word general corpus comprising threads from Lowyat.Net, a popular Internet forum in Malaysia, was created, and the British National Corpus (BNC) was used as the reference corpus. Using the Sketch Engine corpus tool, the three most frequently occurring make LVCs in the Malaysian English corpus were identified. The data was analysed to reveal the differences between the structures of make LVC in Malaysian English and its prototypical structure. The findings show that besides the non-isomorphic deverbal noun form, make LVCs in Malaysian English prefer taking the basic constituents of an LVC. Nativised LVCs are essentially those with zero articles and isomorphic deverbal nouns taking definite articles, determiners, and descriptive adjectives in their modifier slots. The zero article LVC is the most common nativised structure pattern due to the influence of substrate languages in Malaysian English.

Abstract:
The increasing penetration of PV into the distribution grid leads to congestion, causing detrimental power quality issues. Moreover, the multiple small photovoltaic (PV) systems and battery energy storage systems (BESSs) result in increasing conversion losses. A low-voltage DC (LVDC) backbone to interconnect these assets would decrease the conversion losses and is a promising solution for a more optimal integration of PV systems. The multiple small PV systems can be replaced by shared assets with large common PV installations and a large BESS. Sharing renewable energy and aggregation are activities that are stimulated by the European Commission and lead to a substantial benefit in terms of self-consumption index (SCI) and self-sufficiency index (SSI). In this study, the benefit of an LVDC backbone is investigated compared to using a low-voltage AC (LVAC) system. It is found that the cable losses increase by 0.9 percent points and the conversion losses decrease by 12 percent points compared to the traditional low-voltage AC (LVAC) system. The SCI increases by 2 percent points and the SSI increases by 6 percent points compared to using an LVAC system with shared meter. It is shown that an LVDC backbone is only beneficial with a PV penetration level of 65% and that the BESS can be reduced by 22% for the same SSI.

Abstract:
<p>Persian Light Verb Constructions (LVCs) have been studied by many scholars. Yet, little attention has been paid to the process of LVC formation. This paper aims to situate the components of Persian light verb constructions in contexts that can be justifiably invoked as a motivation for LVC formation. We will investigate the issue by arguing that Persian LVCs can be analyzed in terms of incorporation process. This process, explained from a cognitive viewpoint, involves LVCs originating from complete clauses, then passing through a <em>compositional path</em> (Langacker 1987, 2008) where a nonverbal and a verbal element are selected out of a kernel clause and end up in a complex predicate (CPr). The investigation will be primarily focused on the LVCs constructed with<em> </em>LV<em> kardan </em>‘do, make’, as the most frequently used light verb in Persian. The paper will also explore how different paths could be associated with certain particular ‘light’ meanings of<em> kardan. </em>The resulting LVCs may further yield <em>constructional schemas</em> upon which other LVCs formed with a given LV can be formed.</p><p><strong>Keywords: </strong>Light verb construction, Complex predicate, Incorporation, Persian</p>

Abstract. The agricultural Mediterranean areas are dedicated to arable crops (AC), but in the last decades, a significant number of AC has led to a land use change (LUC) to olive grove (OG) and vineyards (V). A field study was conducted to determine the long-term effects (46 years) of LUC (AC by OG and V) and to determine soil organic carbon (SOC), total nitrogen (TN), C : N ratio and their stratification across the soil entire profile, in Montilla-Moriles denomination of origin (D.O.), in Calcic-Chromic Luvisols (LVcc/cr), an area under semiarid Mediterranean conditions. The experimental design consisted of studying the LUC on one farm between 1965 and 2011. Originally, only AC was farmed in 1965, but OG and V were farmed up to now (2011). This LUC principally affected the horizon thickness, texture, bulk density, pH, organic matter, organic carbon, total nitrogen and C : N ratio. The LUC had a negative impact in the soil, affecting the SOC and TN stocks. The conversion from AC to V and OG involved the loss of the SOC stock (52.7% and 64.9% to V and OG respectively) and the loss of the TN stock (42.6% and 38.1% to V and OG respectively). With respect to the stratification ratios (SRs), the effects were opposite; 46 years after LUC increased the SRs (in V and OG) of SOC, TN and C : N ratio.

Full text
Abstract:
The major objective of the research described in this dissertation is the development of new laser vaporization methods for the synthesis of metal and semiconductor nanoparticles, graphene, B- and N-doped graphene, and metal and semiconductor nanoparticles supported on graphene. These methods include the Laser Vaporization Controlled Condensation (LVCC) approach, which has been used in this work for the synthesis of: (1) gold nanoparticles supported on ceria and zirconia nanoparticles for the low temperature oxidation of carbon monoxide, and (2) graphene, boron- and nitrogen-doped graphene, hydrogen-terminated graphene (HTG), metal nanoparticles supported on graphene, and graphene quantum dots. The gold nanoparticles supported on ceria prepared by the LVCC method exhibit high activity for CO oxidation with a 100% conversion of CO to CO2 at about 60 °C. The first application of the LVCC method for the synthesis of these graphene and graphene-based nanomaterials is reported in this dissertation. Complete characterizations of the graphene-based nanomaterials using a variety of techniques including spectroscopic, X-ray diffraction, mass spectrometric and microscopic methods such as Raman, FTIR, UV-Vis, PL, XRD, XPS, TOF-MS, and TEM. The application of B- and N-doped graphene as catalysts for the oxygen reduction reaction in fuel cell applications is reported. The application of Pd nanoparticles supported on graphene for the Suzuki carbon-carbon cross-coupling reaction is reported. A new method is described for the synthesis of graphene quantum dots based on the combination of the LVCC method with oxidation/reduction sequences in solution. The N-doped graphene quantum dots emit strong blue luminescence, which can be tuned to produce different emission colors that could be used in biomedical imagining and other optoelectronic applications. The second method used in the research described in this dissertation is based on the Laser Vaporization Solvent Capturing (LVSC) approach, which has been introduced and developed, for the first time, for the synthesis of solvent-capped semiconductor and metal oxide nanoparticles. The method has been demonstrated for the synthesis of V, Mo, and W oxide nanoparticles capped by different solvent molecules such as acetonitrile and methanol. The LVSC method has also been applied for the synthesis of Si nanocrystals capped by acetonitrile clusters. The acetonitrile-capped Si nanocrystals exhibit strong emissions, which depend on the excitation wavelength and indicate the presence of Si quantum dots with different sizes. The Si and the metal oxide nanoparticles prepared by the LVSC method have been incorporated into graphene in order to synthesize graphene nanosheets with tunable properties depending on graphene-nanoparticle interactions.

Full text
Abstract:
Chemical methods are generally used for the synthesis of active nanoparticles (metals, semi-metals, metal oxides, and etc) supported on high surface area materials. Chemical methods involve using strong solvents, harmful gases (H2 & CO), and high temperature techniques such as high boiling solvents, calcination and pyrolysis. The main drawbacks of using this approach, is the prevalence of chemical agents on nanomaterials which tends to negate its applications. Alternatively, photochemical and photothermal methods are widely being considered for the synthesis and design of nanomaterials. For these studies, the active nanomaterials incorporated within high surface area materials were prepared by the laser vaporization-controlled condensation (LVCC) technique or by the laser irradiation in solution (LIS) technique. The LVCC technique involves the irradiation of a solid target at the focal point of a laser beam (532 nm, 30 Hz) by the Nd: YAG laser inside a chamber that is sandwiched between two steel plates in the presence of high purity He. Whereas, the LIS technique involves the laser irradiation of chemical precursors in aqueous solvents using an unfocused beam. The LVCC technique was used for the preparation of carbonaceous and N-doped carbonaceous TiO2 support materials from MIL-125(Ti) and NH2-MIL-125(Ti) metal organic frameworks, Ge and GeO2 nanostructures, GeOx/PRGO nanocomposite, and the Fe3O4/PRGO nanocomposite. On the other hand, Pd supported on MIL-125(Ti) and NH2-MIL-125(Ti) nanocatalysts, GeO2/RGO, and the poly(ethylene glycol methacrylate-co-bisacrylamide) hydrogels were all prepared by the LIS technique.

Abstract:
La LVNC est une cardiomyopathie rare, caractérisée par une hypertrabéculation et de profonds replis du ventricule gauche. A ce jour, nous ne savons toujours pas si la LVNC résulte d'un défaut se produisant durant le développement cardiaque et si sa gravité dépend du stade embryonnaire auquel l'arrêt de la compaction se produit. Notre objectif a été d'étudier l'évolution pathologique de la LVNC en caractérisant les défauts fonctionnels et en identifiant les mécanismes moléculaires dans des modèles de souris présentant un développement anormal des trabécules ventriculaires. Pour établir un modèle de LVNC, nous avons généré des souris KO conditionnel pour Nkx2.5 grâce au système Flox/loxP inductible par injection de tamoxifène qui active la recombinaison Cre. Nous avons ainsi supprimé l'allèle Nkx2.5 dans l'oreillette et les cardiomyocytes dérivant des trabécules. Nous avons choisi de sipprimé Nkx2.5 au stade embryonnaire E10 quand le trabécule s'accroît, au stade E14 quand il se compacte, ou juste après la naissance quand le cœur a terminé son processus de compaction. En résumé, nous avons réussi à générer différents modèles de LVNC, dans lesquelles nous avons pu étudier cette pathologie, en supprimant le facteur de transcription Nkx2.5 dans les oreillettes et les cardiomyocytes dérivés des trabécules. Nous avons également confirmé que la sévérité de la LVNC dépend du stade de développement du trabécule auquel le défaut se produit. Peu de publications décrivent à ce jour les mécanismes responsables de l'état inflammatoire observé dans la LVNC, nos résultats sont donc prometteurs pour de futures recherches dans cette voie
LVNC is a rare cardiomyopathy, characterized by hypertrabeculation and deep trabecular recesses in the left ventricle. It is still unclear whether LVNC results from a defect occurring during cardiac development. One hypothesis to consider is that the severity of LVNC depends on which embryonic stage the arrest of myocardial compaction occurs. Our aim was to study the pathological evolution of LVNC by characterizing functional defects and identifying molecular mechanisms in mouse models with abnormal ventricular trabeculae development. To establish a LVNC mouse model, we generated specific Nkx2.5 conditional knockout mice to delete Nkx2.5 allele in atria and trabecular derived cardiomyocytes at embryonic stages when trabeculae arise (at around E10), or start to compact (at around E14), or at neonatal stages (after birth) when the heart is almost finish compaction step. After all, we were successful in generating several LVNC mouse models by the conditional deletion of Nkx2.5 transcription factor in atria and trabecular derived cardiomyocytes. These mouse models are suitable for studying LVNC pathology. We also confirmed the hypothesis that the severity of LVNC depends on stages when disturbances in the trabecular development occur. Hypertrabeculation, cardiac conduction defects, decreased ejection fraction, and existence of fibrosis are robustly observed following deletion at E10.5/11.5 meaning that the deletion at early stage of trabecular development causes the most severe pathological phenotype of LVNC. There had been just a few publications showing inflammation in LVNC heart, which could be a very good finding for future researches

The Canine Visceral Leishmaniasis (CVL) is a canidae zoonosis, which infects dogs and other mammals, as humans, becoming a serious public health problem, owing the fact that dogs are the main source infection disease for human on domestic cycle. The closeness to dogs has been referenced as an important disease risk factor. This illness is endemic in several regions from Brazil, including the Paraiba state. In the period of December 2011 to February 2012, in Campina Grande, Paraiba, was conducted a seroepidemiological survey to Leishmania spp. in dogs, through serology study and research from the DNA of the parasite by the molecular biology. This study had a focus on the geographical distribution, correlating the socioeconomic and risk factors. From the 391 studied dogs, 33% showed a positive result to antibodies of Leishmania spp. by IFAT test, 4.34% by ELISA and 2% by PCR with detection of the parasite DNA in the animal blood. There was significant statistical difference to contactants (P = 0.02) and (OR = 4.1). The IFAT with L. major antigen, proved to be a proper confirm test that could be used as counterproof to ELISA test, which presented 39.4% of sensitivity. The combination of these two tests and its co-positivity was only 52%, which required another confirmatory test. However, for the negativity confirmation of IFAT, the ELISA test was considered reliable, with a 96.7% index. The use of PCR with total blood, showed low agreement and sensitivity with IFAT test, therefore not indicated as primary test, however efficient as counterproof. This research shown that CVL has adapted to urban areas, thus as endemic form and it concludes that a variety of diagnostic tests improves the detection of positive animals, becoming an excellent aspect to CVL control in certain areas, besides preventing euthanasia of false positives dogs

In the period of December 2011 to February 2012, in Campina Grande, Paraiba, was conducted a seroepidemiological survey to Leishmania spp. in dogs, through serology study and research from the DNA of the parasite by the molecular biology. This study had a focus on the geographical distribution, correlating the socioeconomic and risk factors. From the 391 studied dogs, 33% showed a positive result to antibodies of Leishmania spp. by IFAT test, 4.34% by ELISA and 2% by PCR with detection of the parasite DNA in the animal blood. There was significant statistical difference to contactants (P = 0.02) and (OR = 4.1). The IFAT with L. major antigen, proved to be a proper confirm test that could be used as counterproof to ELISA test, which presented 39.4% of sensitivity. The combination of these two tests and its co-positivity was only 52%, which required another confirmatory test. However, for the negativity confirmation of IFAT, the ELISA test was considered reliable, with a 96.7% index. The use of PCR with total blood, showed low agreement and sensitivity with IFAT test, therefore not indicated as primary test, however efficient as counterproof. This research shown that CVL has adapted to urban areas, thus as endemic form and it concludes that a variety of diagnostic tests improves the detection of positive animals, becoming an excellent aspect to CVL control in certain areas, besides preventing euthanasia of false positives dogs

Abstract:
Die Linksventrikuläre Noncompaction des Myokards (LVNC) ist eine seltene primäre Herzmuskelerkrankung. Es wird angenommen, dass es sich um eine embryonale Entwicklungsstörung des Myokards handelt. Mutationen in dem X-chromosomalen Gen TAZ sind verantwortlich für Fälle von frühkindlicher LVNC während die genetische Ursache autosomal-dominant vererbter adulter LVNC weitgehend unbekannt ist. In dieser Arbeit wurde die genetische Ursache der LVNC in der Familie LVNC-105 untersucht. Weiterhin wurden in einem großen Kollektiv von LVNC-Indexpatienten Kandidatengenanalysen durchgeführt. Bei der Familie LVNC-105 zeigte die genomweite Kopplungsanalyse nur signifikant hohe 2-Punkt-LOD-Werte auf Chromosom 11p15. Der maximale 2-Punkt-LOD-Wert betrug 5,06 bei D11S902 und der Lokus konnte auf 3,2 Mb (4,9 cM) eingeengt werden. Unter den 40 Genen des Erkrankungslokus war das Kandidatengen CSRP3, das bereits für 2 andere Kardiomyopathien, die dilatative und die hypertrophe Kardiomyopathie (DCM und HCM), als Krankheitsgen beschrieben wurde. Die Sequenzierung des genomischen Bereichs von CSRP3 zeigte keine Mutation bei den betroffenen Familienmitgliedern. Auch die Analyse von weiteren, im Lokus enthaltenen Gene ergab keine Mutation in kodierenden Exons. Auch Untersuchungen auf Transkriptebene offenbarten keine genetische Veränderung. Bei der Sequenzierung der LVNC-Kandidatengene LDB3, LMNA, Nkx2.5 und\linebreak BMP10 bei 63 erwachsenen Indexpatienten mit isolierter LVNC wurde nur eine Mutation in LDB3 gefunden. Erstmals wurden auch 7 Gene, die für sarkomere Proteine kodieren und als Krankheitsgene für HCM und DCM bekannt sind, mittels DHPLC untersucht. Es wurden Mutationen in einem großen Anteil der LVNC-Indexpatienten (19%) in MYH7, ACTC, TPM1 und TNNT2 identifiziert. Klinische Untersuchungen zeigten bei 7 von 12 Patienten mit Mutationen das Vorliegen einer familiären LVNC. In 4 autosomal-dominanten LVNC-Familien kosegregierten die MYH7 Mutationen mit der Erkrankung. MYH7 war mit einem Anteil von 13% das häufigste Krankheitsgen. Die Mutationen in MYH7 lagen vorwiegend in der ATP-Bindungsstelle. LVNC gehört damit zum Spektrum der Kardiomyopathien, die durch Mutationen in sarkomeren Proteinen hervorgerufen werden können.
Left ventricular noncompaction of the myocardium (LVNC) constitutes a rare primary cardiomyopathy. The mechanistic basis is assumed to be an arrest in embryonic cardiac development. Mutations in the X-linked TAZ gene are responsible for cases of infantile LVNC whereas the genetic base of late-onset LVNC in most patients is still unresolved. The objectives of this dissertation were to investigate the genetic defect in family LVNC-105 with autosomal dominant inherited LVNC and to screen a large cohort of patients with isolated LVNC for mutations in candidate genes. In kindred LVNC-105 genome wide linkage analysis revealed significant two-point LOD scores only at chromosome 11p15. A peak 2-point LOD score of 5.06 was obtained with marker D11S902 and a critical interval of 3.2 Mb (4.9 cM) was determined. Among the 40 genes within the disease region one candidate gene was CSRP3, a disease gene for hypertrophic (HCM) and dilated (DCM) cardiomyopathy. Sequence analysis of the genomic CSRP3 region did not reveal mutations in affected family members. Also, analysis of the coding region of further candidate genes contained within the disease locus did not show mutations. Investigations of the genes on transcript level did not detect alterations. Candidate gene analysis of LDB3, LMNA, Nkx2.5 and BMP10 in 63 index patients with isolated LVNC only one mutation was detected in LDB3. For the first time 7 genes encoding sarcomere proteins, known as disease genes for HCM and DCM, were screened for mutations by DHPLC in LVNC patients. Mutations were found in a significant proportion of the cohort of LVNC index patients (19%) in MYH7, ACTC, TPM1 and TNNT2. Clinical evaluations demonstrated familial disease in 7 of 12 probands with sarcomere gene mutations. MYH7 mutations segregated with the disease in 4 autosomal dominant LVNC kindreds. MYH7 was identified as the most prevalent LVNC disease gene (13%) in this cohort. Modified residues in MYH7 were mainly located within the ATP binding site. In conclusion, LVNC belongs to the spectrum of cardiomyopathies originating in molecular defects of the sarcomere.

Abstract:
La forte consommation des énergies fossiles au niveau mondial entraine une raréfaction de ces ressources et met en danger l'équilibre environnemental global du fait de la pollution qu'elle engendre. D'autres sources d'énergie dites renouvelables se développent afin de proposer un mix énergétique très diversifié et progressivement décarboné. Par exemple, dans un contexte urbain, le solaire photovoltaïque présente de nombreux atouts comme la possibilité de produire de l'électricité de façon décentralisée, l'intégration aisée dans les bâtiments et infrastructures publiques, la réduction des pertes liées au transport de l'électricité, pas de pollution sonore, pas ou peu d'impact sur l'écosystème environnant, etc. Cependant, cette source est très intermittente et difficilement prédictible (diverses échelles de temps liées au passage de nuages, cycle diurne ou cycle saisonnier) et doit être implantée dans des endroits sans ombrage d'infrastructure pour assurer la meilleure production et durée de vie. De plus, sa production n'est généralement pas temporellement en phase avec des profils de consommation de type résidentiel ou tertiaire. Afin de répondre à la problématique d'intégration des énergies renouvelables dans nos réseaux électriques conventionnels, l'usage de moyens de stockage, par exemple de type électrochimique, semble aujourd'hui la meilleure solution, en considérant le coût, la sécurité d'approvisionnement, la maturité technologique et la facilité de mise en œuvre. Ainsi, de nouveaux micro-réseaux constitués de sources décentralisées et d'éléments de stockage apparaissent en concurrence du réseau centralisé conventionnel ou en complément de ce dernier afin d'atteindre de nouveaux objectifs (stabilité accrue du réseau, mode isolé de secours en cas de panne avec possibilité d'aider le redémarrage du réseau principal, remplacement de générateurs diesel auxiliaires, etc.). Parmi les grandes transformations actuelles, les consommateurs de plus en plus acteurs et peuvent injecter tout ou partie du surplus d'énergie produit vers le réseau ou choisir de consommer de l'énergie du réseau selon leurs souhaits. Un nouveau modèle économique se dessine avec la possibilité de voir apparaître de nouvelles tarifications de l'électricité notamment liées aux prestations assurant une plus grande robustesse du réseau. Durant cette thèse, plusieurs années de données de production et de consommation d'un bâtiment photovoltaïque ont été analysées pour définir les contraintes imposées à l'unité de stockage assurant l'équilibre du micro-réseau électrique. Un modèle de performance et de vieillissement a été élaboré pour trois technologies de stockage: batteries plomb- acide, batteries lithium-ion et supercondensateurs. Celui-ci permet le dimensionnement, l'association d'éléments de stockage et la gestion optimale des flux énergétiques au sein du micro-réseau. Divers critères permettant d'évaluer le fonctionnement des micro-réseaux ont également été étudiés comme le coût annuel de l'unité de stockage, le taux d'autoconsommation de l'énergie photovoltaïque, la quantité d'énergie qui n'a pas été fournie au consommateur, etc. Une approche multi-objective, basée sur le concept d'optimum de Pareto, a été mise en œuvre afin d'optimiser les aspects économique, environnemental et d'autonomie de fonctionnement des futurs réseaux électriques distribués. Un démonstrateur basse tension continue de quelques kilowatts a été développé pour valider les différents points étudiés dans cette thèse
Because of our global high consumption of fossil fuels, these resources are becoming scarce and the environmental equilibrium of the Earth is endangered. Other energy sources are developed in order to build a new diversified and decarbonised energy mix. For example, in an urban context, the solar photovoltaic system has many assets such as the decentralized production of electricity, easy integration in buildings, transportation losses reduction, no sound during production, low environmental impact, etc. However, the production of this energy source is highly varying, difficult to predict (several timescales, from the cloud shadows to seasonal meteorological variations) and not correlated across time with our consumption needs. In order to enable a massive penetration of renewable energy sources in our conventional grid, the use of energy storage systems (e.g. electrochemical storage) seems a promising solution, taking into account the costs, supply security, technological maturity and ease of set up. Hence, new microgrids constituted by decentralized energy sources and energy storage systems have been developed in order to replace or complement the main centralized grid by ensuring some support functions (i.e. enhancement of the grid stability, black-start operation, replacement of diesel generators, etc.). The consumers become actors able to inject a part of all their surplus energy to the main grid, if the operation is accepted by the transmission system operator. A new business model is to define, especially in the case of putting a valuation on the functions that can help the main grid. During this thesis, several years of data from production and consumption of a photovoltaic building have been analysed in order to define the operating profile of an energy storage system that ensures the equilibrium of the microgrid. A behavioural model taking into account the ageing has been made for three storage technologies: lead-acid batteries, lithium-ion batteries, and supercapacitors. It enables the optimal sizing, the hybrid association of storage systems, and the optimal energy management of the microgrid. Several criteria assessing the operation of microgrids have been studied (e.g. annual cost of the storage system, self-consumption rate, loss of load probability, etc.). A multi-objective methodology, based on Pareto optimality, has been developed in order to optimize economic, environmental, and autonomy aspects. A low voltage DC prototype of some kilowatts has been developed for validating the different concepts presented in this thesis

Dans le contexte d'une crise énergétique, écologique et climatique, l'intégration de sources d'énergie renouvelables dans les réseaux électriques apparait comme une nécessité absolue. Cette thèse propose dans un premier temps une étude bibliographique des technologies de production d'énergie renouvelable, des éléments de stockage d'énergie et des réseaux électriques avec un focus sur les micro-réseaux LVDC. Des méthodologies sont mises en place pour la modélisation de la production photovoltaïque de la plateforme BIPV ADREAM du LAAS-CNRS en se basant sur la base de données intégrée au bâtiment ainsi que pour la modélisation de différentes technologies de stockage électrochimique telles que les batteries au plomb, lithium, polymère ou encore hybrides Carbone. L'hydrogène est étudié comme un possible vecteur d'énergie de demain. Une synthèse est donnée sur ses applications industrielles et comme moyen de stockage d'énergie ainsi que sa production par électrolyse de l'eau en utilisant des sources photovoltaïque, concept nommé " Solar fuels ". Un prototype de chaîne de conversion d'énergie solaire en hydrogène a été conçu en collaboration avec le laboratoire RCAST de Tokyo, et comprenant panneaux photovoltaïques haut rendement à triple jonction, électrolyseurs à taille réduite, architectures de micro-convertisseurs Buck et Boost distribués et éléments de stockage lithium, et est proposé pour la partie expérimentale de cette thèse avec le but d'obtenir un haut rendement tout en permettant un contrôle précis
In the context of an energy, ecological and climate crisis, integrating renewable energy sources in electrical grids appears as an absolute necessity. A bibliographic study of renewable energy production technologies, energy storage elements and electrical grids with a specific focus on LVDC micro-grids is proposed in this thesis. Modeling methodologies for the photovoltaic energy production of the BIPV platform ADREAM of LAAS-CNRS based on the building's integrated database as well as for multiple electrochemical storage technologies such as lead, lithium polymer and hybrid carbon batteries. Hydrogen is investigated as possible vector of energy for the future.

Abstract:
Abstract In the case of conventional planar FET, Dynamic Laser Stimulation (DLS) is a very effective method to isolate marginal failure. Depending on laser sources, DLS is divided by Soft Defect Localization (SDL) and Laser Assisted Device Alteration (LADA). SDL uses 1320nm wavelength laser source in order to induce localized heat. On the other hand, LADA uses 1064nm wavelength laser source to generate photo carriers. But for the FinFET the effect of laser stimulation is not clear yet. This paper introduces the effect of laser stimulation on FinFET transistors based on wavelength, the so called LADA and two-photon LADA. The experimental data show changes in Vth and Idsat with different character for a single FinFET transistor. A case study further explains this laser stimulation effect via scan chain LVcc marginal failure analysis localized with 1320nm CW laser stimulation and nano-probing analysis.

Abstract:
Direct Methanol Fuel Cell (DMFC) is often viewed as an ideal power source for microelectronics and portable devices such as cell phone, laptop computer, and sensor, etc. However, the drawbacks in conventional DMFC (e.g., methanol crossover through the proton exchange membrane and the low concentration of methanol and water mixture) impede the wide commercial applications of DMFC due to the dissatisfactory electrical output. Moreover, the complex system configuration in conventional DMFC increases fuel cell weight, size, and cost and also reduces the system reliability. In this paper, an innovative Local Vapor Fuel Cell (LVFC) was proposed to promote the electro-catalytic reaction and improve the fuel cell power output. The design of LVFC was based on locally vaporizing the mixture of methanol and water without the complex and bulky vaporizer and blower. The capillary-based fuel feeding in LVFC, instead of pumping, substantially reduced system complexity. The proposed design features the LVFC light in weight, compact in size and high fuel conversion efficiency. The thermally stable high temperature membrane materials and MEA for LVFC were also investigated and developed. After the high temperature membrane and MEA were integrated into the LVFC, the characterization of the LVFC was conducted as a function of temperatures. The experimental results demonstrated that LVFC had higher electrical output with the increase of temperature, and higher thermal and electro-chemical reliability and stability.

Abstract:
The paper deals with the use of advanced avionics systems in basic flight training. From the point of view of aviation history, this issue is relatively new, because for many decades only aircraft with analog instruments have been used for training. From the content point of view, the paper can be divided into two significant parts. The first, theoretical part describes the knowledge of the issue. In 2019, two new Zlín Z-242 aircraft equipped with the Garmin G500 TXi glass cockpit were added to the fleet of the Air Training and Education Centre (LVVC). Therefore in the second, practical part we conducted a survey among instructors and students of LVVC on the issue discussed and their experience of training on this aircraft. In addition, we looked at how to effectively train pilots when using training aircraft with advanced avionics systems. Completion of the practical part of the paper was the creation of multimedia learning material, which should help novice pilots prepare for the use of basic features of Garmin G500 TXi and acquaint them with knowledge that will help especially the first flight hours to be more efficient as they begin the training on new aircraft
