Les notions de possession et d'exorcisme en Grèce ancienne à la lumière des auteurs anciens, des phylactères et des PGM

La notion d'un esprit étranger et invisible qui prend possession d'un corps est, croit-on, sémitique. Les peuples proche-orientaux et juifs avaient développé des rituels et des pratiques spécifiques pour s'en débarasser. Les Grecs, pour leur part, avaient parfois à composer avec différentes entités, des daimones, des morts ou des apparitions et parfois des divinités dont les actions pouvaient s'avérer très nuisibles, si ce n'est nettement invasives. Toutefois, la communis opinio maintient que les concepts de la possession et de l'exorcisme ne furent chez eux, que tardivement introduits, et ce, sous l'influence des sémitiques. Pourtant, la littérature et les sources épigraphiques, papyrologiques et archéologiques semblent démontrer que les Grecs avaient déjà, dès l'époque classique, dans leur propre culture et religion, les éléments caractéristiques de la possession et de l'exorcisme. Une analyse approfondie de textes d'auteurs anciens, de formulaires de magie,dont les très connus Papyri Grecs Magiques et de diverses amulettes, apporte des arguments décisifs en ce sens.

The Hybridity of Violence : Location, Dislocation, and Relocation in Contemporary Canadian Multicultural and Indigenous Writing

Cette thèse explore la relation entre les littératures autochtones et multiculturelles du Canada. Même si les critiques littéraires examinent les littératures dites mineures de plus en plus, ces dernières sont rarement étudiées sans la présence médiatrice de la littérature canadienne considérée comme étant dominante. Afin de produire une telle analyse, cette thèse mobilise le concept d’hybridité en tant que catégorie d’analyse de texte qui, en plus de son histoire raciale et coloniale, décrit convenablement les formes d’expérimentations stylistiques que les écrivains autochtones et multiculturels emploient afin de représenter et questionner leur marginalisation. Ne voulant pas reproduire les interprétations fétichistes qui réduisent les littératures autochtones et multiculturelles à leurs représentations de concepts d’altérité, j’examine ces textes dans leurs relations avec différents discours et débats ayant marqué les études littéraires canadiennes, notamment, le long poème canadien, l’écriture des prairies canadiennes, la littérature urbaine, le multiculturalisme, et les premières nations. Ma méthode d’analyse repose sur la façon dont chaque texte étudié alimente ces catégories d’analyse littéraire tout en les modifiant radicalement. De plus, je développe un cadre conceptuel et théorique permettant l’étude de la relation entre les textes autochtones et multiculturels sans toutefois confondre ou réduire les contextes d’où proviennent ces littératures. Ma thèse et ma méthode d’analyse se concrétise par l’interprétation des textes écrits par Armand Garnet Ruffo, Suzette Mayr, Rawi Hage, et Jeannette Armstrong. Le chapitre d’introduction détaille la façon dont la relation entre les textes autochtones et multiculturels a été appréhendée jusqu’à présent. J’y élabore mon cadre théorique qui joint et réinterprète de manière critique diverses théories, dont celle du postcolonialisme, de l’hybridité, et de la mondialisation, et la façon dont ces théories se rapportent aux études littéraires canadiennes. Dans mon deuxième chapitre, j’analyse le long poème d’Armand Garnet Ruffo, Grey Owl: The Mystery of Archie Belaney, en m’attardant particulièrement aux stratégies d’expérimentations stylistiques et génériques que Ruffo développe afin de rendre le genre du long poème canadien autochtone et de questionner l’identité de Grey Owl. Mon troisième chapitre examine Venous Hum, un roman de Suzette Mayr. Ce texte remet en question la tradition de « prairie writing », le multiculturalisme canadien, et le conservatisme albertain à travers son style expérimental, son usage des métaphores et du réalisme magique. Mon quatrième chapitre interprète le roman montréalais Cockroach, de Rawi Hage, en examinant la façon dont ses unités locales, nationales, et globales rencontrent le colonialisme et contestent les discours nationaux une fois que sa critique de la mondialisation se trouve réarticulée dans une approbation des discours d’interventions humanitaires de l’occident. Mon dernier chapitre explore le roman de Jeannette Armstrong, Whispering in Shadows, afin de démontrer les limites de ma méthode d’analyse. Puisque l’hybridité sous-entend inévitablement la notion d’assimilation, son application dans le contexte de l’œuvre d’Armstrong s’avèrerait réductrice. Pour cette raison, ce chapitre utilise des concepts autochtones définis par Armstrong afin de développer une méthode de lecture non-hégémonique. Ma thèse examine donc la façon dont chaque texte déploie le concept d’hybridité pour à la fois contester et enrichir les discours critiques qui tentent de contenir ces textes. Elle contribue aux études postcoloniales de la littérature canadienne en élargissant leur champ habituel pour inclure les complexités des théories de la mondialisation, et en examinant quelles stratégies littéraires les textes autochtones et multiculturels partagent, mais mobilisent à des fins différentes.

Le cinéma d'animation : avènement d'une institution et naissance d'une industrie

Les premiers comptes rendus de l’histoire du cinéma ont souvent considéré les premiers dessins animés, ou vues de dessins animés, comme des productions différentes des films en prise de vue réelle. Les dessins animés tirent en effet leurs sources d’inspiration d’une gamme relativement différente d’influences, dont les plus importantes sont la lanterne magique, les jouets optiques, la féérie, les récits en images et les comics. Le dessin animé n’en demeure pas moins fondamentalement cinématographique. Les vues de dessins animés de la décennie 1900 ne se distinguent ainsi guère des scènes à trucs sur le plan de la technique et du style. D’abord le fait de pionniers issus de l’illustration comique et du croquis vivant comme Émile Cohl, James Stuart Blackton et Winsor McCay, le dessin animé s’industrialise au cours de la décennie 1910 sous l’impulsion de créateurs venant du monde des comics, dont John Randolph Bray, Earl Hurd, Paul Terry et Max Fleisher. Le processus d’institutionnalisation par lequel le dessin animé en viendra à être considéré comme une catégorie de film à part entière dépend en grande partie de cette industrialisation. Les studios de dessins animés développent des techniques et pratiques managériales spécifiquement dédiées à la production à grande échelle de films d’animation. Le dessin animé se crée ainsi sa propre niche au sein d’une industrie cinématographique dont il dépend toutefois toujours entièrement. Ce phénomène d’individuation repose sur des formules narratives et des personnages récurrents conçus à partir de modèles issus des comics des années 1910.

Du modèle du cercle magique à celui de la place du joueur : un apport de l’esthétique de la réception au design de jeux vidéo

Ce mémoire propose une réflexion sur des modèles permettant de mieux comprendre et concevoir l’expérience esthétique d’un jeu vidéo. Ces modèles traduisent différents idéaux de la place du joueur. Comme on peut le constater à travers une réflexion sur le modèle du cercle magique, jouer est souvent compris comme un acte unilatéral d’entrée en imagination dans un monde étranger au monde actuel – toute sortie marquant la pénalité ou la fin du jeu. De ce point de vue, le designer aurait donc pour rôle de placer et de maintenir le joueur dans le monde virtuel représenté pour qu’il s’y sente immergé et présent. Cela dit, comme en témoignent les critiques qui s’élèvent contre le modèle du cercle magique, d’autres stratégies de mise en place du joueur sont à distinguer et à définir pour faciliter l’analyse et la conception des jeux vidéo. Devant ce modèle, jugé limitatif, ce que nous proposons ici est de recourir à quelques outils méthodologiques et typologiques de l’esthétique de la réception en histoire de l’art pour bâtir un modèle plus englobant, celui de la place du joueur, dont nous testons la validité par l’analyse du jeu vidéo God of War III (2010).

De la réception filmique à la participation ludique : prolégomènes d’une étude sur l’énonciation vidéoludique

Ce mémoire étudie la dynamique communicationnelle et interactionnelle entre un joueur et un système de jeu par l’entremise des théories de l’énonciation et de la cognition. Par une analyse des jeux vidéo d’horreur en perspective à la première personne, il s’agit de conceptualiser une spirale heuristique de l’énonciation à partir des principes théoriques du Cycle Magique (Arsenault et Perron, 2009). Le propos se focalise sur la manière dont le joueur expérimente et traite les propositions ludiques et les propositions ludodiégétiques. L’intérêt est d’observer comment la valeur réflexive des marques de jeu et des marques de jouabilité sert à départager des relations d’attribution entre des formulations énonciatives (textuelles, verbales, visuelles, sonores ou procédurales) et des agents énonciatifs. Cette recherche rend compte, d’une part, de la gestion cognitive des faits énonciatifs et, d’autre part, de la modulation de leurs valeurs d’immédiateté-hypermédiateté et de leurs rapports de liaison/déliaison avec les agents énonciatifs. Il est expliqué que cette activité cognitive du joueur dirige la schématisation d’attitudes interactionnelles servant à structurer la signification – ludique ou narrative – des propositions ludiques générées au cours de l’activité de jeu. L’analyse cible des processus de mise en phase performative et de mise en phase méta-systémique ludique permettant la détermination de vecteurs d’immersion. En fonction du caractère d’opacité ou de transparence des vecteurs, il est question d’indiquer comment la posture d’expérience du joueur oscille entre un continuum immersif qui polarise une expérience systémique et une expérience diégétisée.

Influence of residual cations (Na+, K+ and Mg2+) in the alkylation activity of benzene with 1-octene over rare earth metal ion exchanged FAU–Y zeolite

The effect of residual cations in rare earth metal modified faujasite–Y zeolite has been monitored using magic angle spinning NMR spectral analysis and catalytic activity studies. The second metal ions being used are Na+, K+ and Mg+. From a comparison of the spectra of different samples, it is concluded that potassium and magnesium exchange causes a greater downfield shift in the 29Si NMR peaks. Also, lanthanum exchanged samples show migration behavior from large cages to small cages, which causes the redistribution of second counter cations. It is also observed that Mg2+ causes the most effective migration of lanthanum ions due to its greater charge. The prepared systems were effectively employed for the alkylation of benzene with 1-octene in the vapor phase. From the deactivation studies it is observed that the as-exchanged zeolites possess better stability towards reaction condition over the pure HFAU zeolite.

Farm Programmes of Electronic Media: A Comparative Study of Audience Perception in Kerala

Farm communication and extension programs are vital part of the farm development attempts. Electronic media plays a major role in farm extension activities. Kerala, the consumer state, which was a complete agricultural state in pre-independence period, is the sprouting land of agricultural extension and publication activities in print media. Later AIR (All India Radio) farm programs and farm broadcasting of Doordarshan enriched the role of electronic media in farm extension activities. The media saturated southern state of India received this new electronic media farm communication revolution whole heartedly. However, after 1990, Kerala witnessed a flood of private T V channels and currently there are 24 channels in this regional language, named Malayalam. All major news and entertainment channels are broadcasting farm programs. Farm programs of AIR and Doordarshan, broadcasted in Malayalam language, have been well accepted to the farmers‘ in Kerala. However, post-independence period, witnessed the formation of Kerala state in Indian Union and the first ballot-elected communist Government started its administration. After the land reform bills, the state witnessed a gradual decrease in agricultural production. Even if it is not reflected much in the attitude and practices of farm community and farm broadcast of traditional electronic broadcasting, a change is observable after the post-liberalization era of India. Private Television channels, which were focused on entertainment value of programs, started broadcasting farm programs and the parameters of program production went through certain changes. In this situation, there is ample relevance for a study about the farm programs of electronic media in terms of a comparative study of audience perception. The study is limited in the state of Kerala as it is the most media saturated state in India. The study analyzes the rate, nature and scope of adoption of farming methods transmitted through electronic media (T.V. and Radio) in Malayalam language.All kinds of Farm programs including comprehensive program serials, success stories, seasonal cropping methods, experts opinion, been analyzed on the basis of the following objectives.  To find whether propagating new farm methods through farm programs in electronic media or the availability of adequate infrastructure and economic factors make a farmer to adopt a new farming method.  To find which electronic media has more influence on farmers to adopt agricultural programs.  To find which form of electronic media gets better feedback from farmers  To find out whether the programs of T.V. or Radio is more acceptable to farmers than the print media.  To find whether farmers gets the message through their preferred medium for the message. The researcher recorded opinions from a panel of agricultural officers, farm Information officers, agro extension researchers and experts. According to their opinions and guidelines, a pilot study is designed and conducted in Kanjikuzhy Panchayath, in Alappuzha district, Kerala. The Panchayath is selected by considering its ideal nature of being the sample for a social Science research. Besides, the nature of farming in the Panchayath, which devoid of the cultivation of cash crops also supported its sample value. As per the observations from the pilot study, researcher confirmed the Triangulation method as the methodology of research. The questionnaire survey, being the primary part contained 42 Questions with 6 independent and 32 dependent variables. The survey is conducted among 400 respondents in Idukki, Alappuzha and Pathanamthitta districts considering geographical differences and distribution of different types of crops. The response from a total of 360 respondents, 120 from each district, finally selected for tabulation and data analysis.The data analysis, based on percentage analysis, along with the results from focus group discussion among a selected group of 20 farmers, together produced the results as follows. Farmers, who are the audience of farm programs, have a very serious approach towards the medium. They are maintaining a critical point of view towards the content of the programs. Farmers are reasonably aware about the financial side of the programs and the monitory aspirations of both private and Government owned Television channels. Even though, the farmers are not aware on the technical terminology and jargons, they have ideas about success stories, program serials and they are even informed about channels are not maintaining an audience research section like AIR. Though the farmers accept Doordarshan as the credential source of farm information and methods, they are inclined to the entertainment value of programs too. They prefer to have more entertainment value for the programs of Doordarshan. Surprisingly, they have very solid suggestions on even about the shots which add entertainment value to the farm broadcasting methods of Doordarshan. Farmers are very much aware about the fact that media is just an instrument for inspiration and persuasion. They strongly believe that the source of information and new methods is agricultural research and an effective change happens only when there are adequate infrastructure and marketing facilities, along with the proper support from Government agricultural guideline and support systems like Krishi Bhavans. They strongly believe that media alone cannot create any magic in increasing agricultural production. Farmers are pointing out the lack of response to the feedback and queries of farmers on farming methods, as an evidence for the difference in levels of commitment of Government and private owned Television channels.Farmers are still perceiving AIR farm programs are far more committed to farmers and farming than any other electronic medium. However, they are seriously lacking Radio receivers with medium wave reception facility. Farmers perceive that the farming methods on new crops are more adoptable than the farming methods of traditional crops in both private and Government owned Television channels. There are multiple factors behind this observation from farmers. Farmers changed in terms of viewing habits and they prefer success stories, which are totally irrelevant and they even think that such stories encourage people to go for farming and they opined that such stories are good sources of inspiration. However, they are all very much sure about the importance and particular about the presence of entertainment factor even in farm programs. Farmers expect direct interaction of any expert of the new farming method to implement the method in their agriculture practices. Though introduction of a new idea in the T.V. is acceptable, farmers need the direct instruction of expert on field to start implementing the new farming practices Farmers still have an affinity towards print media reports and agricultural pages and they have complaints to print media on the removal of agricultural information pages from news papers. They prefer the reports in print media as it facilitates them to collect and refer articles when they need it. Farmers are having an eye of doubt about the credibility of farm programs by private T.V. channels. Even if they prefer private Television channels for listening and adopting new farming methods and other farm information, they scrutinize programs to know whether they are sponsored programs by agrochemical or agro-fertilizer manufacturer.

Quasilocal density functional theory and its application within the extended Thomas-Fermi approximation

In this paper we propose a generalization of the density functional theory. The theory leads to single-particle equations of motion with a quasilocal mean-field operator, which contains a quasiparticle position-dependent effective mass and a spin-orbit potential. The energy density functional is constructed using the extended Thomas-Fermi approximation and the ground-state properties of doubly magic nuclei are considered within the framework of this approach. Calculations were performed using the finite-range Gogny D1S forces and the results are compared with the exact Hartree-Fock calculations

Superheavy nuclei in relativistic effective Lagrangian model

Isotopic and isotonic chains of superheavy nuclei are analyzed to search for spherical double shell closures beyond Z=82 and N=126 within the new effective field theory model of Furnstahl, Serot, and Tang for the relativistic nuclear many-body problem. We take into account several indicators to identify the occurrence of possible shell closures, such as two-nucleon separation energies, two-nucleon shell gaps, average pairing gaps, and the shell correction energy. The effective Lagrangian model predicts N=172 and Z=120 and N=258 and Z=120 as spherical doubly magic superheavy nuclei, whereas N=184 and Z=114 show some magic character depending on the parameter set. The magicity of a particular neutron (proton) number in the analyzed mass region is found to depend on the number of protons (neutrons) present in the nucleus.

A structural investigation relating to the pozzolanic activity of rice husk ashes

Various factors determine the applicability of rice husk ash (RHA) as a pozzolanic material. The amount and accessibility of reactive sites is thought to be a key factor. A structural study of RHA samples in relation to their reactivity has been performed; Silica in RHA formed by burning rice husk in a laboratory furnace under continuous supply of air have been characterized as a function of incineration temperature, time and cooling regime. The characterization methods included chemical analyses, conductivity measurements, microscopic analysis, X-ray diffraction (XRD) and 29Si magic-angle spinning (MAS) nuclear magnetic resonance (NMR). In line with earlier observations, the analyses show that the highest amounts of amorphous silica occur in samples burnt in the range of 500 °C–700 °C. The 29Si NMR data allow direct identification of the reactive silanol sites in the RHA samples. De-convolution of the NMR spectra clearly shows that the quickly cooled RHA resulting from burning rice husk for 12 h at 500 °C has the highest amount of silanol groups. This sample also induced the largest drop in conductivity when added to a saturated calcium hydroxide solution giving an indication of its reactivity towards lime. Therefore, this RHA is the favorable sample to be used as pozzolanic cement additive

Eros and Thanatos in Ernest Hemingway's "The Short Happy Life of Francis Macomber" and Angela Carter's "Master"

According to Hemingway all good prose has the dignity and draught of an iceberg. This is especially true of Hemingway's short stories. "Francis Macomber" counts among the best composed short stories in English. Interpretation sways between Hemingway's idealisation of the male code and its deconstruction. Is the White Hunter a British scourge of American values or is Margot the tragic victim of a newly founded male friendship? Is the open ending rather a hunting accident or the mean murder of an unloved spouse? Hemingway gives hitherto uninterpreted clues by mentioning strategies of big game hunting and ballistics. Carter's magic story "Master"; deals with the regression of a White Hunter who has become 'his own negative'. An Englishman dissolves into the Amazonian jungle and is killed by his own victim. The story can be read as a macabre crime of sexuality and murder or as a dystopian warning of the future of mankind if we go on exploiting and destroying our planet.

Composition and stability of organic matter fractions in soils under different land use regimes

Soil organic matter (SOM) vitally impacts all soil functions and plays a key role in the global carbon (C) cycle. More than 70% of the terrestric C stocks that participate in the active C cycle are stored in the soil. Therefore, quantitative knowledge of the rates of C incorporation into SOM fractions of different residence time is crucial to understand and predict the sequestration and stabilization of soil organic carbon (SOC). Consequently, there is a need of fractionation procedures that are capable of isolating functionally SOM fractions, i.e. fractions that are defined by their stability. The literature generally refers to three main mechanisms of SOM stabilization: protection of SOM from decomposition by (i) its structural composition, i.e. recalcitrance, (ii) spatial inaccessibility and/or (iii) interaction with soil minerals and metal ions. One of the difficulties in developing fractionation procedures for the isolation of functional SOM fractions is the marked heterogeneity of the soil environment with its various stabilization mechanisms – often several mechanisms operating simultaneously – in soils and soil horizons of different texture and mineralogy. The overall objective of the present thesis was to evaluate present fractionation techniques and to get a better understanding of the factors of SOM sequestration and stabilization. The first part of this study is attended to the structural composition of SOM. Using 13C cross-polarization magic-angle spinning (CPMAS) nuclear magnetic resonance (NMR) spectroscopy, (i) the effect of land use on SOM composition was investigated and (ii) examined whether SOM composition contributes to the different stability of SOM in density and aggregate fractions. The second part of the present work deals with the mineral-associated SOM fraction. The aim was (iii) to evaluate the suitability of chemical fractionation procedures used in the literature for the isolation of stable SOM pools (stepwise hydrolysis, treatments using oxidizing agents like Na2S2O8, H2O2, and NaOCl as well as demineralization of the residue obtained by the NaOCl treatment using HF (NaOCl+HF)) by pool sizes, 13C and 14C data. Further, (iv) the isolated SOM fractions were compared to the inert organic matter (IOM) pool obtained for the investigated soils using the Rothamsted Carbon Model and isotope data in order to see whether the tested chemical fractionation methods produce SOM fractions capable to represent this pool. Besides chemical fractionation, (v) the suitability of thermal oxidation at different temperatures for obtaining stable SOC pools was evaluated. Finally, (vi) the short-term aggregate dynamics and the factors that impact macroaggregate formation and C stabilization were investigated by means of an incubation study using treatments with and without application of 15N labeled maize straw of different degradability (leaves and coarse roots). All treatments were conducted with and without the addition of fungicide. Two study sites with different soil properties and land managements were chosen for these investigations. The first one, located at Rotthalmünster, is a Stagnic Luvisol (silty loam) under different land use regimes. The Ah horizons of a spruce forest and continuous grassland and the Ap and E horizons of two plots with arable crops (continuous maize and wheat cropping) were examined. The soil of the second study site, located at Halle, is a Haplic Phaeozem (loamy sand) where the Ap horizons of two plots with arable crops (continuous maize and rye cropping) were investigated. Both study sites had a C3-/C4-vegetational change on the maize plot for the purpose of tracing the incorporation of the younger, maize-derived C into different SOM fractions and the calculation of apparent C turnover times of these. The Halle site is located near a train station and industrial areas, which caused a contamination with high amounts of fossil C. The investigation of aggregate and density fractions by 13C CPMAS NMR spectroscopy revealed that density fractionation isolated SOM fractions of different composition. The consumption of a considerable part (10–20%) of the easily available O-alkyl-C and the selective preservation of the more recalcitrant alkyl-C when passing from litter to the different particulate organic matter (POM) fractions suggest that density fractionation was able to isolate SOM fractions with different degrees of decomposition. The spectra of the aggregate fractions resembled those of the mineral-associated SOM fraction obtained by density fractionation and no considerable differences were observed between aggregate size classes. Comparison of plant litter, density and aggregate size fractions from soil under different land use showed that the type of land use markedly influenced the composition of SOM. While SOM of the acid forest soil was characterized by a large content (> 50%) of POM, which contained high amounts of spruce-litter derived alkyl-C, the organic matter in the biologically more active grassland and arable soils was dominated by mineral-associated SOM (> 95%). This SOM fraction comprised greater proportions of aryl- and carbonyl-C and is considered to contain a higher amount of microbially-derived organic substances. Land use can alter both, structure and stability of SOM fractions. All applied chemical treatments induced considerable SOC losses (> 70–95% of mineral-associated SOM) in the investigated soils. The proportion of residual C after chemical fractionation was largest in the arable Ap and E horizons and increased with decreasing C content in the initial SOC after stepwise hydrolysis as well as after the oxidative treatments with H2O2 and Na2S2O8. This can be expected for a functional stable pool of SOM, because it is assumed that the more easily available part of SOC is consumed first if C inputs decrease. All chemical treatments led to a preferential loss of the younger, maize-derived SOC, but this was most pronounced after the treatments with Na2S2O8 and H2O2. After all chemical fractionations, the mean 14C ages of SOC were higher than in the mineral-associated SOM fraction for both study sites and increased in the order: NaOCl < NaOCl+HF ≤ stepwise hydrolysis << H2O2 ≈ Na2S2O8. The results suggest that all treatments were capable of isolating a more stable SOM fraction, but the treatments with H2O2 and Na2S2O8 were the most efficient ones. However, none of the chemical fractionation methods was able to fit the IOM pool calculated using the Rothamsted Carbon Model and isotope data. In the evaluation of thermal oxidation for obtaining stable C fractions, SOC losses increased with temperature from 24–48% (200°C) to 100% (500°C). In the Halle maize Ap horizon, losses of the young, maize-derived C were considerably higher than losses of the older C3-derived C, leading to an increase in the apparent C turnover time from 220 years in mineral-associated SOC to 1158 years after thermal oxidation at 300°C. Most likely, the preferential loss of maize-derived C in the Halle soil was caused by the presence of the high amounts of fossil C mentioned above, which make up a relatively large thermally stable C3-C pool in this soil. This agrees with lower overall SOC losses for the Halle Ap horizon compared to the Rotthalmünster Ap horizon. In the Rotthalmünster soil only slightly more maize-derived than C3-derived SOC was removed by thermal oxidation. Apparent C turnover times increased slightly from 58 years in mineral-associated SOC to 77 years after thermal oxidation at 300°C in the Rotthalmünster Ap and from 151 to 247 years in the Rotthalmünster E horizon. This led to the conclusion that thermal oxidation of SOM was not capable of isolating SOM fractions of considerably higher stability. The incubation experiment showed that macroaggregates develop rapidly after the addition of easily available plant residues. Within the first four weeks of incubation, the maximum aggregation was reached in all treatments without addition of fungicide. The formation of water-stable macroaggregates was related to the size of the microbial biomass pool and its activity. Furthermore, fungi were found to be crucial for the development of soil macroaggregates as the formation of water-stable macroaggregates was significantly delayed in the fungicide treated soils. The C concentration in the obtained aggregate fractions decreased with decreasing aggregate size class, which is in line with the aggregate hierarchy postulated by several authors for soils with SOM as the major binding agent. Macroaggregation involved incorporation of large amounts maize-derived organic matter, but macroaggregates did not play the most important role in the stabilization of maize-derived SOM, because of their relatively low amount (less than 10% of the soil mass). Furthermore, the maize-derived organic matter was quickly incorporated into all aggregate size classes. The microaggregate fraction stored the largest quantities of maize-derived C and N – up to 70% of the residual maize-C and -N were stored in this fraction.
