Abstract:

Сучасний ринок електроенергії, швидкими темпами, переформовується з традиційного, в свої часи добре сформованого, типу електроенергетичного видобутку у, так званий, нетрадиційний або альтернативний. Сильні позиції, із стрімким розвитком, у цій формації зайняла вітрова енергетика. Середній показник росту світового вітроенергетичного сектора на рік становить більш ніж 26%.

Актуальність теми. Сучасна людина піддається впливу великої кількості несприятливих чинників оточуючого середовища матеріального та інформаційного характеру, що пов’язані з прогресуючим погіршенням екологічного стану довкілля. Загрозливим для біологічних об’єктів поряд з радіаційним випромінюванням є токсичний вплив різноманітних хімічних елементів чи їх сполук. В зв’язку з інтересом науковців до проблеми негативного впливу ксенобіотиків, зокрема важких металів на біохімічні процеси в організмі проводиться величезна кількість досліджень, присвячених впливу сполук важких металів на живі об’єкти

Syftet med denna studie är att undersöka vilka uppfattningar elever i årskurs 4 har om fenomenet liv.

Abstract:

Previous literature concerning citrus and other tree crops led us to ask if there was molecular evidence for mycoplasma -like organisms (MLOs) as the causal agent of Macrophylla decline and two other decline diseases, citrus blight and lemon sieve tube necrosis. We had molecular probes available to us that were either specific for MLOs of tree diseases and others that were universal for all known types of MLOs. We used a polymerase chain reaction (MLO) to determine if MLOs were present in the vascular tissues of decline and healthy citrus. I all trials performed, the trees were negative for ML

Abstract:

Bacteria are an integral part of our lives. They don’t only surround us externally, but also live inside us. Most people think that the bacteria are harmful micro-organisms, but they are wrong. Along with the pathogenicity, they play an important role in ensuring the normal functioning of our body. Microbial colonies found on or in the body are normally benign or beneficial. Bacteria are the basis of the normal microflora of many systems, especially of the digestive tract. These microbial colonies carry out a series of helpful and necessary functions, such as aiding in digestion. They also pro

Tip growth is the primary form of growth in hyphal organisms and some plant cells. Tip growth in hyphae is highly dependent on F-actin, which acts to regulate and support growth.

Abstract:

The microflora inhabiting the human gastrointestinal tract can be considered an essential 'metabolic organ', in a symbiotic relationship with its host. Due to the low cultivability and inappropriate sampling methodology the microflora is poorly explored and ill-defined. Preliminary, molecular-based research at the University of Waikato revealed the presence of 16S rRNA gene sequences originating from novel Mollicute-like species inhabiting the human GI tract. A ~830bp 'consensus' sequence representing these novel Mollicute-like sequences was classified within the Mollicute Genus Anaeroplasma t

Abstract:

The ability of animals to vary growth, development rate and behaviour in response to environmental conditions has been well documented, particularly during the larval phase in animals with complex life cycles. The evolution and maintenance of plasticity in response to environmental conditions is likely to be adaptive in animals that face unpredictable environments. However, there are two aspects of life histories in animals with complex life cycles, which would be expected to favour plasticity, that have received limited attention: traits during metamorphic climax and variation in the life his

Abstract:

The automatic synthesis of embodied creatures through artificial evolution has become a key area of research in robotics, artificial life and the cognitive sciences. However, the research has mainly focused on genetic encodings and fitness functions. Considerably less has been said about the role of controllers and how they affect the evolution of morphologies and behaviors in artificial creatures. Furthermore, the evolutionary algorithms used to evolve the controllers and morphologies are pre-dominantly based on a single objective or a weighted combination of multiple objectives, and a large

We use mathematical models to explore the evolutionary implications of health interventions affecting age-dependent mortality schedules in two contexts, antihelminthics targeting parasitic nematodes, and programs directed against malaria vectors.

Interventions may therefore generate selection favouring later-maturing, larger and more fecund worms, rather than inevitably fav

Abstract:

Le rhum de la distillerie de Savanna est obtenu après fermentation par les levures puis distillation d'un mout constitué de mélasse et d'eau. Nous avons donc étudié la composition de la mélasse. Celle-ci se révèle riche en composés aromatiques qui sont à l'origine des nombreux composés chimiques présents dans les rhums. Nous avons identifié plus de 100 composés chimiques dans la mélasse dont un isomère de la béta-damascenone. Cet isomère pourrait présenter les notes organoleptiques caractéristiques du rhum. Un travail particulier sur des précurseurs d'arômes existant sous forme glycosylée a ét

Abstract:

Le risque de contamination des réseaux par les légionelles est aujourd'hui bien connu. Ces bactéries sont naturellement résistantes à un certain nombre de stress, elles peuvent survivre de façon prolongée dans les biofilms et proliférer de façon très importante via une croissance intracellulaire dans les amibes. Les amibes peuvent elles-mêmes présenter une résistance élevée aux traitements de décontamination usuels et offrent donc une protection supplémentaire aux légionelles. Si l'association amibes-légionelles dans les réseaux a été largement étudiée, il n'en est pas de même pour un certain

Abstract:

Les plantes dans leur environnement établissent des interactions avec des micro-organismes du sol. Parmi ces interactions nous pouvons distinguer les symbioses associatives mettant en jeu des bactéries PGPR (Plant Growth Promoting Rhizobacteria). L'impact de ces microorganismes phytobénéfiques (Azospirillum, Pseudomonas...) sur le métabolisme de la plante hôte est encore mal connu. Le modèle d'étude que nous avons choisi dans le cadre de ce travail est Zea mays L. qui peut établir de nombreuses symbioses associatives avec des PGPR.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment

Les cils sont des organites très conservés au cours de l'évolution des eucaryotes et présents à la surface de presque tous les types cellulaires. Ils sont constitués d'une structure microtubulaire, l'axonème, entourée d'une membrane en continuité avec la membrane plasmique. Ils sont nucléés par un corps basal, centriole ancré à la surface cellulaire. Grâce aux nombreux récepteurs qu'ils concentrent à leur membrane, tous les cils sont des senseurs de leur environnement. Ils peuvent aussi être motiles et assurer, par leur battement coordonné, le déplacement relatif de la cellule et du fluide env

Abstract:

Calcium signaling is fundamental for decoding a variety of extra- and intra-cellular signaling pathways and for the regulation of many cellular functions. Mitochondria play a fundamental role in controlling Ca2+ dynamics inside the cell. Their strategic subcellular distribution ensures the efficient coupling between the release of Ca2+ from the stores and its uptake into the organelle, thus guaranteeing the control of the cell death/cell survival pathways and of the energy homeostasis. Since the identification of the mitochondrial calcium uniporter (MCU) and its regulators, the biochemical and

Abstract:

L’écologie comparative a mis en évidence des associations récurrentes entre les traits fonctionnels des plantes et leur environnement. Ces relations peuvent varier selon le niveau d’organisation considéré – au sein des espèces, entre les espèces, et entre groupes d’espèces –, mais cette dépendance demeure peu étudiée. Une distinction fondamentale dans les théories de l’histoire de vie est effectuée entre espèces annuelles (réalisant leur cycle de vie en une année) et pérennes (cycle de vie sur plus d’une année, avec généralement plusieurs événements de reproduction). Les annuelles et les péren

L'utilisation d'organismes génétiques modèles a permis l'investigation à grande échelle de mécanismes cellulaires et moléculaires pour la biologie. La larve de poisson zèbre (Danio rerio) est un organisme vertébré modèle simple qui présente plusieurs avantages pour identifier les bases moléculaires et pharmacologiques du développement et du comportement à travers des cribles génétiques et chimiques respectivement. Plusieurs paradigmes expérimentaux reposent sur une caractérisation précise du phénotype comportemental associé avec un génotype ou l'application d'une drogue. Ce processus de phénot

Abstract:

L'acidification des océans (AO) est un phénomène induit par l'augmentation de la pression partielle en CO2 (pCO2) atmosphérique d'origine anthropique caractérisé par une diminution du pH de l'eau de mer et une modification des paramètres de la chimie des carbonates. L'AO est susceptible d'impacter toutes les espèces marines mais les organismes calcifiants y seraient les plus sensibles. Dans le cadre de cette thèse, les réponses physiologiques des algues Corallinacées (algues rouges calcaires) et de la crépidule (mollusque gastéropode) ont été étudiées sous des conditions de pCO2 actuelles et p

Abstract:

Dans le domaine du diagnostic in vitro, l'étape d'extraction de micro-organismes à partir d'un échantillon complexe est une étape clé pour permettre l'identification du pathogène responsable d'une infection. Pour les septicémies, cette étape d'extraction est généralement précédée d'une étape de culture, ce qui conduit à une obtention des résultats au bout de plusieurs jours. Un résultat plus rapide (typiquement inférieur à 24h) permettrait d'augmenter le taux de survie des patients, et aurait ainsi une forte valeur ajoutée pour le corps médical.

Abstract:

La température est un facteur clef en écologie qui module les fonctions biologiques des organismes vivants. Cet impact est d’autant plus fort chez les animaux ectothermes dont le métabolisme dépend de la température environnementale et de ses variations. Chez ces espèces, le réchauffement induit une accélération de leur croissance mais aussi la diminution de leur taille adulte. Si ces patrons sont souvent observés au cours d’une génération, leur évolution et les mécanismes sous-jacents restent encore méconnus à ce jour. En milieu aquatique, l’élévation de la température peut diminuer la dispon
