Microévolution en temps réel : étude quantitative dans les populations naturelles d'Artemia spp. / Microevolution in action : a quantitative case study on natural populations of Artemia spp.

Rode, Nicolas 20 July 2012 (has links)
La compréhension des processus microévolutifs ayant lieu dans la nature nécessite la quantification des principales forces sélectives s'exerçant sur les populations sauvages. Ces 10 dernières années, les études à long terme et l'écologie de la résurrection (qui fait revivre des stades en dormance) ont été les principales approches pour étudier l'évolution des traits d'histoire de vie sur plusieurs générations dans les populations sauvages. Mon travail consiste à comprendre comment des facteurs écologies simples (p. ex. la température) et des interactions interspécifiques ou intraspécifiques plus complexes (p. ex. les interactions antagonistes hôte-parasite ou mâle-femelle) façonnent le processus évolutif des populations sauvages. Dans cette optique, j'ai utilisé l'Artémia comme un organisme modèle, en combinant des études sur le terrain et en laboratoire. Premièrement, j'ai étudié l'évolution de la niche thermique avec une approche d'écologie de la résurrection, en utilisant une série temporelle d'œufs de dormance d'une population d' introduite à partir de marais salants de régions tempérées dans des marais salants tropicaux dans les années 80. Cette étude montre que la survie aux températures élevées (caractéristiques du nouvel environnement) a augmenté linéairement au cours du temps à partir de l'introduction, suggérant un taux d'adaptation constant sur plus de 100 générations. Deuxièmement, j'ai utilisé une approche similaire pour étudier l'adaptation entre males et femelles dans une autre population d'Artémia. Cette étude suggère que les conflits sexuels provoquent une dynamique de coévolution fluctuante dans la nature sur une échelle d'environ 100 générations. Troisièmement, j'ai étudié les impacts respectifs de différents parasites (une espèce de cestode et deux espèces de microsporidie) sur la compétition entre une espèce d'hôte autochtone asexuée et une espèce d'hôte invasive sexuée. Chacun des trois parasites étaient soit spécialiste d'une espèce ou de certains génotypes d'hôte. De plus, l'espèce de cestode dont l'effet castrateur chez l'hôte est bien connu infectait uniquement l'espèce autochtone, suggérant que ce parasite joue un rôle majeur dans la compétition entre les espèces d'hôte autochtones et invasives. Par ailleurs, les trois espèces de parasite semblaient manipuler le comportement d'agrégation de leur hôte, très probablement pour augmenter leur transmission à de nouveaux hôtes. Enfin, j'ai réalisé des études de génétiques des populations d'espèces asexuées diploïdes et polyploïdes d'Artemia et d'espèces sexuées asiatiques proches. Les espèces asexuées diploïdes produisent des mâles rares et il semblerait que ceux-ci permettent une faible fréquence de reproduction sexuée. De plus, l'hybridation d'espèces d'Artémia éloignée phylogénétiquement a donné naissance à au moins trois lignées polyploïdes indépendantes. / Getting a comprehensive understanding of microevolution in natural populations requires proper quantification of the important selective forces exerted on these populations. Over the last decade, long-term studies and resurrection-ecology (revival of resting stages) have been the main approaches to study life history trait evolution over many generations in the wild. My work aims at understanding how simple ecological factors (e.g. temperature) and complex interactions between and within species (host-parasite and male-females antagonistic interactions) shape evolutionary processes in natural populations. To this end, I used the brine shrimp Artemia as a model system and combined laboratory and field studies. First, I investigated thermal niche evolution with a resurrection ecology approach, using dormant-egg time series from an Artemia population introduced from temperate to tropical salterns in the mid-80's. This experiment shows that survival at the high temperatures typical of the new environment increased linearly through time after the introduction, suggesting a sustained rate of adaptation over more than 100 generations. Second, I used the same approach to study adaptation between sexes in another Artemia population. I found that sexual conflicts result in fluctuating male-female coevolutionary dynamics in natura, over a time scale of ~100 generations. Third, I studied the relative role of one cestode and two microsporidian parasites in mediating the competition between a native asexual host and an invasive bisexual host. I found that all three parasites were either host- or genotype-specific and that the castrating cestode parasite specifically infected the native species, suggesting that this parasite actually played a major role in the competition between native and invasive hosts. Interestingly, all three parasites manipulated the swarming behavior of their host, most likely to increase their transmission. Fourth, I performed population genetic studies of diploid and polyploid Artemia parthenogenetica and their Asian bisexual close relatives. Diploid asexual Artemia produce rare males and I found indication that these males allow some rare sex in this otherwise parthenogenetic species. In addition, hybridization between divergent Artemia species has led to the origin of at least three independent polyploid lineages.

Prisikėlusio kūno savybės pagal šiuolaikinį teologinį mokymą / Qualities of a ressurected body, following the modern teological teaching

Mikutytė, Vytautė 02 August 2013 (has links)
Šiandien Bažnyčia kviečia iš naujo apmąstyti mūsų tikėjimą prisikėlimu, be kurio ir likusios tikėjimo tiesos tampa nebesuprantamos. Prisikėlusio kūno savybių nagrinėjimas leidžia suvokti busimo prisikėlimo tikrovę ir prisikėlimo kūniškumą. Pagrindinis šio magistro studijų baigiamojo darbo tikslas – aptarti prisikėlusio iš numirusių žmogaus kūno savybes pagal šiandieninį oficialų Bažnyčios mokymą ir pagal paskirų šiandieninių teologų svarstymus. Siekiant užsibrėžto tikslo iškeliami tokie uždaviniai: 1. Pristatyti tikėjimo kūno prisikėlimu vystymosi radą Šventajame Rašte 2. Atskleisti būsimo visų žmonių prisikėlimo ir Kristaus prisikėlimo ryšį 3. Remiantis antropologiniu žmogaus vientisumu atskleisti sielos ir kūno ryši ir pagrįsti prisikėlusio kūno tapatumą su žemėje gyvenusiu kūnu bei prisikėlusių žmonių tarpusavio ryšį. 4. Remiantis tradicinių fizikinių kūno savybių skirstymo pristatyti prisikėlusio kūno savybes. Darbo eigoje prisikėlusio kūno savybės yra lyginamos su tradicinėm šešiomis kūno savybėmis, tačiau tai nėra šio darbo pagrindas. Šio darbo centre – prisikėlusio kūno kūniškumas. Darbe ieškoma atsakymų į tokius klausimus: ar priskėlęs kūnas bus kūniškas (materijos prasme), ir kokia prasme jis bus kūniškas? Kaip šis kūniškumas reikšis? Kokiu būdu šis prisikėlęs kūnas gali būti tas pats kūnas, kuriame dabar gyvename? Jei siela yra substancianali savo kūno forma, tai kokiu būdu ji gali egzistuoti kūnui suyrus? Kokiu būdu derėtų suprasti prisikėlusio asmens lytiškumą... [toliau žr. visą tekstą] / Vytautė Mikutytė. Qualities of a Ressurected Body, Following the Modern Teological Teaching: Master's Thesis in Christian Anthropological Pedagogy/ Supervisor Assoc. Prof. Saulius Rumšas; Lithuanian University of Educational Sciences, Department of Catholic Religion Education, - Vilnius, 2013, - 60 pg. The church is currently inviting us to rethink our belief in resurrection, without which, the rest of the truths of faith would become incomprehensible. The analysis of the qualities of a resurrected body allows to comprehend the reality and corporeality of the future resurrection. The main aim of the Master's Thesis is to discuss the qualities of a resurrected body, based on the official teachings of contemporary church as well as the statements of individual theologians. The following objectives were raised: 1. To present the development of faith in resurrection found in the Holy Scripture. 2. To determine the connection between the future human resurrection and the resurrection of Christ. 3. To show the connection between the body and the soul and to ground the relation between the identity of resurrected body and the living body as well as the interrelation between the resurrected people, based on the anthropological wholeness of a human. 4. To present the qualities of a resurrected body, based on the classification of traditional, physical properties of a body. In the Thesis, the qualities of a resurrected body are compared to the six traditional body... [to full text]

Intertemporální účinky derogačních nálezů Ústavního soudu / Intertemporal effects of derogational decisions of the Constitutional Court

Askari, Daniel January 2016 (has links)
The thesis deals with temporal effects of decisions of the Constitutional Court, by which a statute is repealed due to its unconcstitutionality. Since the relevant provisions are not sufficiently comprehensive, various problems and doubts arise in legal reality. The thesis summarizes the relevant theoretical premises, which should allow for finding answers to questions related to the topic of the thesis. The relevant case-law is also summerized and subjected to partial criticism. The paper also deals with specifics of criminal law and civil law, including horizontal effect. It also specifically addresses the issue concrete constitutional review a and the phenonmenon of so called resurrection of law when a derogational statute is derogated.

Hope for today and tomorrow : G. C. Berkouwer's doctrines of providence and resurrection with regard to the current topics of the 9/11 terrorism attack on America and the rise of hyper-preterism

Loomis, Van L. 06 1900 (has links)
This dissertation argues for the hope that is found in G. C. Berkouwer’s doctrines of providence and bodily resurrection in relation to the terrorist attack on September 11, 2001, and the rising pervasiveness of the doctrine of hyperpreterism among American Reformed circles. In Part I of the dissertation, Berkouwer’s doctrine of providence is explained and then evaluated and applied. By way of explanation and exposition, Berkouwer’s knowledge of providence is examined, along with his theology of providence in sustenance and government, in relation to miracles, and the dilemma of the existence of God and evil. Following that is an evaluation and application of the doctrine to the 9/11 terrorist attack on America. In Part II, a theological/doctrinal study is undertaken concerning the doctrine of resurrection. Hyper-preterism is examined, along with its leading proponents, and placed into interaction with Berkouwer’s views of the doctrine of the physical resurrection of the body at the eschaton. / Theology / M.Th.

Kříž v proměnách věků a jeho význam v lidské společnosti / The Cross in Changing of Times and its Significance in Ancient Society

Roule, Radek January 2016 (has links)
The Cross in Changing of Times and its Significance in Ancient Society The cross is the most widespread symbol appearing worldwide right from the prehistoric times. Though being formed of a very simple shape of two intersecting lines the significance is far reaching. This dissertation looks at the cross both as a sign pointing beyond itself and concentrates on the diversity of its visual appearance. It tries to trace back the possible factors preceding Antiquity influencing the formation of the actual shape in that particular period of history. Although for most part the cross is understood in its connection with the Crucifixion of Christ its history is far more complex beginning in pre-Christian era. The biblical texts present more or less mere allusions of the cross itself. Seen typologically the cross may be understood as the element connecting both Old and New Testament creating a sort of a bridge between them. The careful analysis of the Early Christian documents brings several terms used for the same reality. The most significant are - σταυρός with the Latin equivalent crux and ξύλου (wood) with the Latin equivalent lignum. Later on these give a way to a more general term of σημεῖον (sign) and finally to a symbolic expression "σύμβολον σωτηρίας" (sign-symbol of salvation). The early Christian writers...

Vzkříšení a svobodná vůle z pohledu křesťanské gnóze / The Ressurection and free will from the gnostic view

KOZÁKOVÁ, Barbora January 2010 (has links)
The thesis describes the relationship between the ancient Gnosticism as we know it from the Nag Hammadi library and as it is described in the works of early church fathers and New Testament. It outlines basic topics similar to all versions of a classical cosmogenic Gnostic myth. The subject of the faith in the resurrection of Jesus Christ and its relationship to the establishing a Church structure is discussed. Another topic is the problem of human free will and that of good and evil and its consequences for human morale. The ways of different understanding to it are presented, based on Old Testament story of Adam and Eve as reffered to in the book of Genesis.

Propojení duchovních proudů východu a západu a křesťanský aspekt v učení O.M. Aivanhova. / The Synthesis of Eastern and Western Spiritualities and the Christian Aspect in the Teaching of O.M. Aivanhov

AVRAMOVA, Radka January 2010 (has links)
This work discourses about the teaching of bulgarian {--} french philosopher, pedagogue and spiritual teacher Omraam Mikhaël Aivanhov. It is divided in several thematic chapters discoursing always a certain philosofical {--} spiritual theme from the point of view how is it treated in the teaching of Aivanhov. Among those themes are for example: Creation, Good and evil, About God, Jesus and Christ, Reincarnation, Soul, Ressurection, Holy Trinity. Aivanhov has fresh and undogmatic approach to these themes and he accents that his teaching can serve to a man for the practical work on him or herself. He does not stick to any particular tradition neither he arteficially syncretizes. He rather sees the various levels of the creation and its Creator as a reality which has universal laws and principles. And a mission of man is according to Aivanhov to discover those laws and principles and to live in harmony with them.
