Multivariate analysis of pollen frequency of the native species Escallonia pulverulenta (Saxifragaceae) in Chilean honeys

The aim of this work was the identification of geographic zones suitable for the production of honeys in which pollen grains of Escallonia pulverulenta (Ruiz & Pav.) Pers. (Saxifragaceae) can be detected. The analysis of botanical origin of 240 honey samples produced between La Serena and Puerto Mont (the IV and X Administrative Regions of Chile), allowed the detection of pollen grains of E. pulverulenta in 46 Chilean honeys. The geographic distribution of the honeys studied is presented together with their affinities, through factor analysis and frequency tables. The study was based on the presence of E. pulverulenta pollen. Escallonia pulverulenta pollen percentages oscillated between 0.24% and 78.5%. Seventeen of the studied samples were designated as unifloral - i.e. samples showing more than 45% pollen of a determined plant species. Two of these corresponded to E. pulverulenta (corontillo, madroño or barraco) honeys. The remaining unifloral honeys correspond to 8 samples of Lotus uliginosus Schkuhr (birdsfoot trefoil), 2 samples of Aristotelia chilensis (Molina) Stuntz (maqui) and 1 sample of Escallonia rubra (Ruiz & Pav.) Pers. (siete camisas), Eucryphia cordifolia Cav. (ulmo or muemo), Weinmannia trichosperma Cav. (tineo), Rubus ulmifolius Schott (blackberry) and Brassica rapa L. (turnip). Honeys with different percentages of E. pulverulenta pollen - statistically analyzed through correspondence analysis - could be associated and assigned to one of three geographic types, defined on the basis of this analysis. The geographical type areas defined were the Northern Mediterranean Zone (samples from the IV Region), Central Mediterranean Zone (samples from the V to the VIII regions including two samples of unifloral Escallonia pulverulenta honey), and Southern Mediterranean Zone (samples from the IX Region).

Chromosome polymorphism in Ctenomys minutus (Rodentia-Octodontidae)

A sample of 101 specimens of Ctenomys minutus was collected along its geographic range. Eight karyotypes (2n = 42, 45, 46a, 46b, 47, 48, 49 and 50) were found. The chromosome polymorphisms were due to Robertsonian rearrangements and tandem fusions. The distribution of polymorphisms indicated three population blocks: northern (2n = 49 and 50), central (2n = 46a, 47, and 48) and southern (2n = 42, 45, and 46b). These findings suggest that this species is undergoing a speciation process due to geographic isolation.

Amplification of 9q34 in childhood adrenocortical tumors: a specific feature unrelated to ethnic origin or living conditions

Adrenocortical tumors (ACT) in children under 15 years of age exhibit some clinical and biological features distinct from ACT in adults. Cell proliferation, hypertrophy and cell death in adrenal cortex during the last months of gestation and the immediate postnatal period seem to be critical for the origin of ACT in children. Studies with large numbers of patients with childhood ACT have indicated a median age at diagnosis of about 4 years. In our institution, the median age was 3 years and 5 months, while the median age for first signs and symptoms was 2 years and 5 months (N = 72). Using the comparative genomic hybridization technique, we have reported a high frequency of 9q34 amplification in adenomas and carcinomas. This finding has been confirmed more recently by investigators in England. The lower socioeconomic status, the distinctive ethnic groups and all the regional differences in Southern Brazil in relation to patients in England indicate that these differences are not important to determine 9q34 amplification. Candidate amplified genes mapped to this locus are currently being investigated and Southern blot results obtained so far have discarded amplification of the abl oncogene. Amplification of 9q34 has not been found to be related to tumor size, staging, or malignant histopathological features, nor does it seem to be responsible for the higher incidence of ACT observed in Southern Brazil, but could be related to an ACT from embryonic origin.

Regional variations of deformation mechanisms in the Lorrain Quartzite near Whitefish Falls, Ontario, Canada /

The quartzite microfabric found in the Lorrain Formation was studied across the La Cloche syncline, along a regional north-south transect along highway 6, near Whitefish Falls, Ontario. The complete stratigraphic sequence across the syncline is preserved, and is present on each fold limb. The lithostratigraphic units with the smallest grains size and lowest mica content are located close to the core of the fold, while coarser grained mica and feldspar rich units are situated at the northern and southern most extent of the transect. Deformation mechanisms vary with lithology and with position across the fold. Pressure solution appears to be the dominant deformation mechanism in the feldspathic, micaceous and ferruginous units. In the finer grained, mica poor white medium grained and cherty sandstone units, grain boundary migration (GBM) characteristics show dominance over those of pressure solution and show high amounts of fracturing which cut migrated boundaries and therefore post date GBM. All samples across the fold display a preferred orientation of quartz c-axes. The senses of asymmetry of fabrics are found to be similar across the syncline, with the exception of the ferruginous sandstone unit. Formation of these similar fabrics synmietries can not be the result of strain related to first order folding. The mica content appears to be related to the percentage of quartz lost due to pressure solution as a result of strain; the more mica present, the less quartz was lost. Calculations based on the shape of initial grains suggest that conservatively 30% of the quartz volume has been dissolved out of the Lorrain quartzite, and potentially migrated hundreds of meters to other members of the Huronian Supergroup as there was no meso or macroscopic evidence observed in outcrop.

Diatoms as indicators of lake trophic status

Relationships between surface sediment diatom assemblages and lake trophic status were studied in 50 Canadian Precambrian Shield lakes in the Muskoka-Haliburton and southern Ontario regions. The purpose of this study was to develop mathematical regression models to infer lake trophic status from diatom assemblage data. To achieve this goal, however, additional investigations dealing with the evaluation of lake trophic status and the autecological features of key diatom species were carried out. Because a unifying index and classification for lake trophic status was not available, a new multiple index was developed in this study, by the computation of the physical, chemical and biological data from 85 south Ontario lakes. By using the new trophic parameter, the lake trophic level (TL) was determined: TL = 1.37 In[1 +(TP x Chl-a / SD)], where, TP=total phosphorus, Chl-a=chlorophyll-a and SD=Secchi depth. The boundaries between 7 lake trophic categories (Ultra-oligotrophic lakes: 0-0.24; Oligotrophic lakes: 0.241-1.8; Oligomesotrophic lakes: 1.813.0; Mesotrophic lakes: 3.01-4.20; Mesoeutrophic lakes: 4.21-5.4; Eutrophic lakes: 5.41-10 and Hyper-eutrophic lakes: above 10) were established. The new trophic parameter was more convenient for management of water quality, communication to the public and comparison with other lake trophic status indices than many of the previously published indices because the TL index attempts to Increase understanding of the characteristics of lakes and their comprehensive trophic states. It is more reasonable and clear for a unifying determination of true trophic states of lakes. Diatom specIes autecology analysis was central to this thesis. However, the autecological relationship of diatom species and lake trophic status had not previously been well documented. Based on the investigation of the diatom composition and variety of species abundance in 30 study lakes, the distribution optima of diatom species were determined. These determinations were based on a quantitative method called "weighted average" (Charles 1985). On this basis, the diatom species were classified into five trophic categories (oligotrophic, oligomesotrophic, mesotrophic, mesoeutrophic and eutrophic species groups). The resulting diatom trophic status autecological features were used in the regressIon analysis between diatom assemblages and lake trophic status. When the TL trophic level values of the 30 lakes were regressed against their fi ve corresponding diatom trophic groups, the two mathematical equations for expressing the assumed linear relationship between the diatom assemblages composition were determined by (1) uSIng a single regression technique: Trophic level of lake (TL) = 2.643 - 7.575 log (Index D) (r = 0.88 r2 = 0.77 P = 0.0001; n = 30) Where, Index D = (0% + OM% + M%)/(E% + ME% + M%); 4 (2) uSIng a' multiple regressIon technique: TL=4.285-0.076 0%- 0.055 OM% - 0.026 M% + 0.033 ME% + 0.065 E% (r=0.89, r2=0.792, P=O.OOOl, n=30) There was a significant correlation between measured and diatom inferred trophic levels both by single and multiple regressIon methods (P < 0.0001, n=20), when both models were applied to another 20 test lakes. Their correlation coefficients (r2 ) were also statistically significant (r2 >0.68, n=20). As such, the two transfer function models between diatoms and lake trophic status were validated. The two models obtained as noted above were developed using one group of lakes and then tested using an entirely different group of lakes. This study indicated that diatom assemblages are sensitive to lake trophic status. As indicators of lake trophic status, diatoms are especially useful in situations where no local trophic information is available and in studies of the paleotrophic history of lakes. Diatom autecological information was used to develop a theory assessing water quality and lake trophic status.

Étude de la résistance aux antibiotiques des entérocoques d'origine animale du Québec

Les entérocoques font partie de la flore normale intestinale des animaux et des humains. Plusieurs études ont démontré que les entérocoques d’origine animale pouvaient représenter un réservoir de gènes de résistance aux antibiotiques pour la communauté humaine et animale. Les espèces Enterococcus faecalis et Enterococcus faecium sont importantes en santé publique; elles sont responsables d’environ 12% de toutes les infections nosocomiales aux États-Unis. Au Canada, les cas de colonisation et/ou d’infections à entérocoques résistants à la vancomycine ont plus que triplé de 2005 à 2009. Un total de 387 isolats E. faecalis et E. faecium aviaires, et 124 isolats E. faecalis porcins ont été identifiés et analysés pour leur susceptibilité aux antibiotiques. De hauts pourcentages de résistance envers les macrolides et les tétracyclines ont été observés tant chez les isolats aviaires que porcins. Deux profils phénotypiques prédominants ont été déterminés et analysés par PCR et séquençage pour la présence de gènes de résistance aux antibiotiques. Différentes combinaisons de gènes de résistance ont été identifiées dont erm(B) et tet(M) étant les plus prévalents. Des extractions plasmidiques et des analyses par hybridation ont permis de déterminer, pour la première fois, la colocalisation des gènes erm(B) et tet(M) sur un plasmide d’environ 9 kb chez des isolats E. faecalis porcins, et des gènes erm(B) et tet(O) sur un plasmide de faible poids moléculaire d’environ 11 kb chez des isolats E. faecalis aviaires. De plus, nous avons démontré, grâce à des essais conjugatifs, que ces plasmides pouvaient être transférés. Les résultats ont révélé que les entérocoques intestinaux aviaires et porcins, lesquels peuvent contaminer la viande à l’abattoir, pouvaient représenter un réservoir de gènes de résistance envers la quinupristine-dalfopristine, la bacitracine, la tétracycline et les macrolides. Afin d’évaluer l’utilisation d’un antisérum polyclonal SA dans l’interférence de la résistance à de fortes concentrations de bacitracine (gènes bcrRAB), lors d’un transfert conjugatif répondant aux phéromones, un isolat multirésistant E. faecalis aviaire a été sélectionné. Après induction avec des phéromones produites par la souche réceptrice E. faecalis JH2-2, l’agrégation de la souche donatrice E. faecalis 543 a été observée ainsi que des fréquences de transfert élevées en bouillon lors d’une courte période de conjugaison. Le transfert conjugatif des gènes asa1, traB et bcrRAB ainsi que leur colocalisation a été démontré chez le donneur et un transconjugant T543-1 sur un plasmide de 115 kb par électrophorèse à champs pulsé (PFGE) et hybridation. Une CMI de > 2 048 µg/ml envers la bacitracine a été obtenue tant chez le donneur que le transconjuguant tandis que la souche réceptrice JH2-2 démontrait une CMI de 32 µg/ml. Le séquençage des gènes asa1, codant pour la substance agrégative, et traB, une protéine régulant négativement la réponse aux phéromones, a révélé une association de cet élément génétique avec le plasmide pJM01. De plus, cette étude présente qu’un antisérum polyclonal SA peut interférer significativement dans le transfert horizontal d’un plasmide répondant aux phéromones codant pour de la résistance à de fortes doses de bacitracine d’une souche E. faecalis aviaire multirésistante. Des isolats cliniques E. faecium d’origine humaine et canine ont été analysés et comparés. Cette étude rapporte, pour la première fois, la caractérisation d’isolats cliniques E. faecium résistants à l’ampicilline (EFRA) d’origine canine associés à CC17 (ST17) au Canada. Ces isolats étaient résistants à la ciprofloxacine et à la lincomycine. Leur résistance envers la ciprofloxacine a été confirmée par la présence de substitutions dans la séquence en acides aminés des gènes de l’ADN gyrase (gyrA/gyrB) et de la topoisomérase IV (parC/parE). Des résistances élevées envers la gentamicine, la kanamycine et la streptomycine, et de la résistance envers les macrolides et les lincosamides a également été observées. La fréquence de résistance envers la tétracycline était élevée tandis que celle envers la vancomycine n’a pas été détectée. De plus, aucune résistance n’a été observée envers le linézolide et la quinupristine-dalfopristine. Les données ont démontré une absence complète des gènes esp (protéine de surface des entérocoques) et hyl (hyaluronidase) chez les isolats canins EFRA testés tandis qu’ils possédaient tous le gène acm (adhésine de liaison au collagène d’E. faecium). Aucune activité reliée à la formation de biofilm ou la présence d’éléments CRISPR (loci de courtes répétitions palindromiques à interespaces réguliers) n’a été identifiée chez les isolats canins EFRA. Les familles de plasmide rep6 and rep11 ont significativement été associées aux isolats d’origine canine. Les profils PFGE des isolats d’origine humaine et canine n'ont révélé aucune relation (≤ 80%). Ces résultats illustrent l'importance d'une utilisation judicieuse des antibiotiques en médecine vétérinaire afin d’éviter la dissémination zoonotique des isolats EFRA canins. Nous pensons que ces résultats contribueront à une meilleure compréhension des mécanismes de résistance aux antibiotiques et de leurs éléments mobiles ainsi qu’à de nouvelles stratégies afin de réduire le transfert horizontal de la résistance aux antibiotiques et des facteurs de virulence.

Circuitos, perturbaciones y transformaciones de la modernidad/colonialidad : análisis discursivo en contextos chilenos y canadienses

La présente étude constitue une analyse comparative de discours qui articulent la problématique de l’héritage coloniale et des réclamations autochtones au Chili et au Canada : des livres de texte de sciences sociales, des discours d’opinion et des discours autochtones. Nous proposons que les similitudes surprenantes qui ont été révélées par les contextes nationaux canadiens et chiliens peuvent être expliquées, en partie, par leur articulation avec le discours globalisé de la modernité/colonialité. D’une part, les textes scolaires et les discours d’opinion font circuler des éléments discursifs de la modernité, tout en reproduisant des formes de savoir et de dire coloniaux. D’autre part, les discours autochtones se ressemblent entre eux dans la mesure où ils interpolent la modernité/colonialité transformant ainsi les termes d’engagement interculturel. Bien que les états canadiens et chiliens renforcent leur engagement à l’égard de la réconciliation avec les Autochtones durant les dernières décennies, les conflits interculturels continuent à se produire en impliquant toujours les mêmes acteurs : l’état, différents peuples autochtones, des entreprises privées, ainsi que des membres de l’élite intellectuelle, politique et patronale. En prenant en compte cette situation, l’objectif de cette thèse vise à mieux comprendre pourquoi ces conflits, loin d’être résolus, continuent à se reproduire. Dans ces deux pays, la problématique des conflits interculturels est fondamentalement mise en rapport avec la question des droits territoriaux et, par conséquent, sont inséparables de la question de l’héritage coloniale des états nationaux canadien et chilien. Pourtant cette dimension coloniale des conflits a tendance à être cachée autant par la rhétorique multiculturelle du discours national que par les polarisations produites par l’opinion publique, lesquelles ont l’habitude d’encadrer la problématique par des notions binaires, telles que « civilisation/barbarie » ou « authenticité/illégitimité ». De plus, on peut considérer l’ouest du Canada et le sud du Chili comme étant des contextes comparables, puisque ceux-ci ont été colonisés avec la base du discours moderne du progrès et de la civilisation, qui a servi à légitimer l’expansion de l’état national au dix-neuvième siècle. Cependant, il n’existe que très peu d’études qui comparent les productions discursives relatives aux relations interculturelles entre Autochtones et non Autochtones dans les contextes canadiens et chiliens, possiblement à cause des différences linguistiques, sociohistoriques et politiques qui paraissent insurmontables.

L'expédition de la France au Liban sous Napoléon III (1860-1861)

L’Empire ottoman, au XIXe siècle, s’affaiblit sans cesse et paraît destiné à s'effondrer. Il est l’objet de convoitises et de rivalités entre les puissances européennes. Sous sa suzeraineté, la Syrie et, avec elle, la région du Mont-Liban, est une zone clé sur le plan stratégique puisqu'elle domine l’accès aux voies menant à l’Inde et à l’Asie méridionale et orientale. La France et l'Angleterre tentent toutes deux de s'y imposer par communautés locales interposées : la première à travers les Maronites, la seconde à l'aide des Druzes. Au printemps 1860, des troubles éclatent entre les deux communautés, entraînant le massacre de milliers de chrétiens. Les puissances européennes, poussées par le gouvernement de Napoléon III, s'entendent pour intervenir au moyen d'une commission d'enquête et l'envoi de troupes. Cette expédition a pour mission officielle d’aider l’Empire ottoman à rétablir l’ordre et à protéger les chrétiens. Le présent mémoire démontre que la France impériale entretenait des visées politiques et économiques à l'égard de la Syrie et du Liban. L'historiographie n'avait jusqu'à présent pas analysé en profondeur les véritables mobiles français dans cette expédition. Les ambitions politiques et économiques ont été beaucoup plus déterminantes dans la décision française de mettre en branle l'expédition que le devoir « humanitaire » de protection des chrétiens ou la satisfaction de son opinion publique. Loin de se laisser abattre par la catastrophe que représentent les massacres qui menace la survie de sa clientèle et donc de son influence en Syrie, Paris, et particulièrement son ministre des Affaires étrangères E. Thouvenel, a réussi à tourner la situation à son avantage. Se servant habilement du désir d'ingérence des autres puissances et de son rôle de protectrice des chrétiens, la France est parvenue à acculer au pied du mur l'Angleterre, qui s'opposait à l'intervention, et à justifier celle-ci sur des principes éloignés de ses objectifs réels. Les troubles ont finalement constitué pour elle une occasion d'augmenter l'autonomie de la Montagne par rapport au pouvoir central et la puissance économique et politique de sa clientèle à travers la révision du statut administratif de la région. Ce faisant, elle a renforcé son influence dans l'Est méditerranéen et fait un pas de plus vers une domination française en Syrie.

Study on Solid Waste Management : An Economic Analysis with Respect to Ernakulam District

This thesis analyzed waste generation and waster disposal problems in municipalities and Cochin Corporation in Ernakulam district.Then the potential of resource recovery and recycling from biodegradable and non bio-degradable waste is established.The study further focused on the need for segregation of waste at the source as biodegradable and non biodegradable solid waste.The potential of resource recovery is explained in detail through the case study.The thesis also highlights the economically viable and environmental friendly methods o f treatment of waste.But the problem is that concerted and earnest attempts are lacking in making use of such methods.In spite of the health problems faced,people living near the dump sites are forced to stay there either because of their weak economic background or family ties.The study did not calculate the economic cost of health problems arising out of unscientific and irresponsible methods of waste disposal.

Biogeochemistry of the shelf sediments of south eastern Arabian sea: Effect on benthic bacterial heterotrophs

The composition and variability of heterotrophic bacteria along the shelf sediments of south west coast of India and its relationship with the sediment biogeochemistry was investigated. The bacterial abundance ranged from 1.12 x 103 – 1.88 x 106 CFU g-1 dry wt. of sediment. The population showed significant positive correlation with silt (r = 0.529, p< 0.05), organic carbon (OC) (r = 0.679, p< 0.05), total nitrogen (TN) (r = 0.638, p< 0.05), total protein (TPRT) (r = 0.615, p< 0.05) and total carbohydrate (TCHO) (r = 0.675, p< 0.05) and significant negative correlation with sand (r = -0.488, p< 0.05). Community was mainly composed of Bacillus, Alteromonas, Vibrio, Coryneforms, Micrococcus, Planococcus, Staphylococcus, Moraxella, Alcaligenes, Enterobacteriaceae, Pseudomonas, Acinetobacter, Flavobacterium and Aeromonas. BIOENV analysis explained the best possible environmental parameters i.e., carbohydrate, total nitrogen, temperature, pH and sand at 50m depth and organic matter, BPC, protein, lipid and temperature at 200m depth controlling the distribution pattern of heterotrophic bacterial population in shelf sediments. The Principal Component Analysis (PCA) of the environmental variables showed that the first and second principal component accounted for 65% and 30.6% of the data variance respectively. Canonical Correspondence Analysis (CCA) revealed a strong correspondence between bacterial distribution and environmental variables in the study area. Moreover, non-metric MDS (Multidimensional Scaling) analysis demarcated the northern and southern latitudes of the study area based on the bioavailable organic matter

Analysis of Pleistocene paleodrainage evolution in the Po Basin (Italy) by multivariate statistical techniques

In order to obtain a high-resolution Pleistocene stratigraphy, eleven continuously cored boreholes, 100 to 220m deep were drilled in the northern part of the Po Plain by Regione Lombardia in the last five years. Quantitative provenance analysis (QPA, Weltje and von Eynatten, 2004) of Pleistocene sands was carried out by using multivariate statistical analysis (principal component analysis, PCA, and similarity analysis) on an integrated data set, including high-resolution bulk petrography and heavy-mineral analyses on Pleistocene sands and of 250 major and minor modern rivers draining the southern flank of the Alps from West to East (Garzanti et al, 2004; 2006). Prior to the onset of major Alpine glaciations, metamorphic and quartzofeldspathic detritus from the Western and Central Alps was carried from the axial belt to the Po basin longitudinally parallel to the SouthAlpine belt by a trunk river (Vezzoli and Garzanti, 2008). This scenario rapidly changed during the marine isotope stage 22 (0.87 Ma), with the onset of the first major Pleistocene glaciation in the Alps (Muttoni et al, 2003). PCA and similarity analysis from core samples show that the longitudinal trunk river at this time was shifted southward by the rapid southward and westward progradation of transverse alluvial river systems fed from the Central and Southern Alps. Sediments were transported southward by braided river systems as well as glacial sediments transported by Alpine valley glaciers invaded the alluvial plain.
