Carboxysomes provide an avenue for narrowing the timing of evolutionary events in groups of cyanobacteria that are ecologically dominant in modem marine environments - groups that may have an integral role in oxygenating the Earth's atmosphere. Here I show that using concatenated phylogenies of carbon fixation proteins better informs the horizontal gene transfer event that brought carboxysomes from purple sulfur bacteria into marine cyanobacteria and that this gene history aids in constraining the evolutionary timing of carbon fixation. Genes encoding the proteins for the a-carboxysomal shell as well as RuBisCO and carbonic anhydrase are co-located on the genomes of various cyanobacteria in the Prochlorococcus and Synechococcus groups. Previous studies have shown that these genes were likely horizontally transferred together from Chromatiales (purple sulfur bacteria), a group of phototrophic Gammaproteobacteria. While many of these genes are highly conserved and thus yield poorly resolved phylogenies, their concatenation clarifies a shared evolutionary history. This work integrates gene transfer with molecular clock calibration methods to determine divergence times. Accordingly, I evaluate the relationship between atmospheric evolution and the ecology of important groups of phototrophs.

Повний текст джерелаFire is as a main succession driver in northeastern American boreal forests and time since last fire (TSLF) is seen as a useful covariate to infer the spatial variation of carbon. The first two objectives of this thesis are: (1) to elaborate a TSLF map over an extensive region in boreal forests of eastern Canada (217,000 km2) and (2) to predict aboveground carbon biomass (ABC) as a function of TSLF at a scale related to fire disturbances. A non-parametric model was first developed to predict TSLF using historical records of fire, forest inventory data and climate data at a 2-km2 scale. Two kilometer square is the minimum size for fires to be considered important enough and included in the Canadian large fire database. Overall, we found a substantial agreement at the scale of both the study area and landscape units, but the accuracy remained fairly low at the scale of individual 2-km2 cells. A hierarchical modeling approach is then presented for scaling-up ABC from inventory plots to the same 2 km2 scale. The proportions of cover density classes were the most important variables to predict ABC. ABC was also related to the speed of post-fire canopy recovery through which TSLF acts indirectly upon ABC. Finally, we compared remote sensing based aboveground biomass estimates with our inventory based estimates to provide insights on improving their accuracy. The results indicated again that abundances of canopy cover density classes of surficial deposits, and TSLF may serve as ancillary variables for improving substantially the accuracy of remotely sensed biomass estimates. The study results have shown: 1) the importance of lengthening the historical records of fire records to provide a better perspective of the actual changes of fire regime; 2) the importance of incorporating post-fire canopy recovery information together with ABC yield curves in carbon budget models at a spatial scale related to fire disturbances; 3) the importance of adding disturbance history and vegetation recovery trends with remote sensing reflectance data to improve accuracy for biomass mapping.

Повний текст джерелаA Nb-Ti microalloyed steel was chosen to be studied, since microalloying often increases susceptibility to transverse cracking. After in-situ melting and solidification, tensile test specimens were subjected to the thermal history typical of a continuously cast billet. Different amounts of prior deformations in various schedules were imposed on the specimens at selected stages during the thermal history, before tensile testing to fracture at the time and temperature corresponding to the unbending stage of the billet casting. It was found that the hot ductility varied from 1% to 98%, depending on the stage in the thermal history at which prior deformation was executed. Microstructural studies showed remarkable changes in the precipitation pattern occurred due to the employed prior deformation. Similar hot ductility measurements executed on a low carbon steel, that was free from microalloy elements, exhibited an effect of prior hot deformation which was quite different to the Nb-Ti microalloyed steel. In particular, the effect on the hot ductility was not as dramatic. The effects were also postulated to be due to precipitation.

These include relative permeability end points effect, hysteresis effect, fracture spacing and additives of simultaneous injection of carbon dioxide with CO and H2S. Optimization runs were carried out on a mildly heterogeneous 3D model for variety of cases. When compared with the base case, the optimized case led to an increase of 20% in the amount of oil that is recovered
and more than 95% of the injected CO2 was trapped as solution gas on and as an immobile gas. Finally, an investigation of the economical feasibility was accomplished. NPV values for various cases were obtained, selected and studied yielding in a number of cases that are found to be applicable for the field of concern.

Повний текст джерелаThis thesis questions the capacity of cities to seize the energy issue through history, then through a low carbon perspective. It is based on assumptions that the introduction of energy as a local resource, is to become a reason for low carbon transition in cities. The historicity of this transition indicates that its lineaments are sometimes identifiable before the advent of its imperatives. Through a territorial history of energy, the thesis contributes to decoding keys of interest of cities to the low carbon transition as well as "its atomic elements" at the local scale.The city of Metz has a Local Distribution Company (ELD), rare in France, created under German annexation in 1901: Usine d'Electricité de Metz (UEM). The company produces and distributes electricity and heat. It belongs to the city (85%) and consolidates public finances while developing local and / or renewable resources.Saarbrücken, the capital of a German coal and industrial land, seems reluctant to the low carbon transition. However, in the years 1980-1990, the city and its "Stadtwerk" (German ELD) challenged nuclear power-plants and played the role of laboratory for renewables. The energy transition in Saarbrücken also shows ruptures, coal path dependencies, and illustrates the non-linearity of the process. Depending on the historical characteristics of cities and the exogenous pressures on urban supply, low-carbon energy transitions interest local actors to different extents and take various forms and rhythms

Повний текст джерелаSituated at the interface of biology and the humanities, the anthropology of food is a privileged field for the study of ancient societies. Reconstructing the food of the past in all its complexity and diversity can only be achieved by combining the various available sources. Traditionally, the diet of past populations has been studied by historians (written sources) and archaeologists (material sources), but today the development of techniques of biological analysis on human samples offers new ways of tackling this issue. We have chosen the case study of Yakutia, as the abundance of historical and ethnographic data provide a solid contextual framework, and tombs discovered in the permafrost allow access not only to artefacts and funeral meals, but also to very well preserved biological samples. The study of the diet of the Yakuts, who are traditionally horse and cattle breeders, is part of European colonial history and therefore illustrates the transition from a traditional way of life to one dominated by a market economy, in a particular environment where the temperature can reach -71° C in winter. The territory of Yakutia, spread over three million square kilometers, includes various biotopes with valleys and lakes rich in pastures in Central Yakutia and Viluy, and mountainous regions in the North less favourable for breeding, where hunting has always remained an important food source. Our objective is to reconstruct the evolution of the Yakut diet, and to determine its regional particularities as well as those of its social (as determined by artefacts found in the tombs) and sexual categories. To achieve these objectives, we compared data from several sources: 1. The synthesis of historical sources, documents of Russian administration -- some of them unpublished --, as well as ethnographic descriptions from the 17th century to the beginning of the 20th century, which attest that the diet of the Yakuts was mainly based on the products of horse and cattle breeding, while hunting, fishing, and gathering served as a source of supplementary food, in a variable way depending on the region. They attest to the diversity of dairy products and the consumption of various plants. A profound transformation of society after the arrival of the Russians is due to the sedentarization of the Yakuts, with the development of cattle breeding and a decline in the number of horses. Trade also introduced new products. Finally, the agriculture instituted by the Russians gradually replaced the gathering and preparation of the cambium of trees, used until then as flour. 2. The study of archaeological artefacts (food remains, dishes and smoking accessories), deposited in more than 150 tombs during the period extending from the 15th century to the beginning of the 19th century, highlights the important role of food offerings (meat and dairy products) in funeral rites prior to mass Christianization in the 19th century. 3. The analysis of stable isotopes of carbon and nitrogen on the bone collagen of 61 buried subjects and 19 fauna samples (including 11 archaeological and 8 modern) distinguishes meat and fish consumption. It reveals differences of diet by geographic region, and a stable diet among the wealthier Yakuts. [...]

This practical retrofit scheme is a strong alternative to strengthen low to mid-rise deficient reinforced concrete (RC) structures in Turkey. The advantages of the FRP applications, to name a few, are the speed of construction and elimination of the need for building evacuation during construction. In this retrofit scheme, infill walls are adopted to the existing frame system by using FRP tension ties anchored the boundary frame using FRP dowels. Results of experiments have previously shown that FRP strengthened infill walls can enhance lateral load carrying capacity and reduce damage by limiting interstory drift deformations. In previous, analytical studies, a detailed mathematical model and a simplified version of the model for compression struts and tension ties was proposed and verified by comparing model estimations with test results. In this study, an existing 9-storey deficient RC building located in Antakya was chosen to design and apply a hybrid strengthening scheme with FRPs and reduced number of shear walls. Linear elastic analysis procedure was utilized (force based assessment technique) along with the rules of Mode Superposition Method for the reftrofit design. FRP retrofit scheme was employed using the simplified model and design was conducted such that life safety performance criterion is satisfied employing elastic spectrum with 10% probability of exceedance in 50 years according to the Turkish Earthquake Code 2007. Further analytical studies are performed by using Modal Pushover and Nonlinear Time-History Analyses. At the end of these nonlinear analyses, performance check is performed according to Turkish Earthquake Code 2007, using the strains resulting from the sum of yield and plastic rotations at demand in the critical sections. CFRP retrofitting works started at October 2008 and finished at December 2008 for the building mentioned in this study. Eccentric reinforced concrete shearwall installation is still being undertaken. All construction business is carried out without evacuation of the building occupants. This project is one of the first examples of its kind in Turkey.

Immediately after World War I, the Commandant of the United States Marine Corps implemented an officer education program. Called the Marine Corps Schools (MCS), the Commandant, Major General John A. Lejeune, gave the schools the mission of educating officers throughout their career. MCS struggled during its first decade of existence due to operational tempo and a poor curriculum. The direction of MCS changed greatly with the assignment of James Carson Breckinridge as the commanding officer in 1928. The purpose of this thesis is to examine the role Breckinridge, an unconventional and intellectual officer, played in reviving the MCS and turning it into the authority on Small Wars and Amphibious Operations. It will show that Breckinridge, drawing on observations made of college education systems, focused the Marine Corps Schools on the task of teaching officers to analyze problems and find solutions and not rely on memorized book answers.

Повний текст джерелаDuring the years of 1950 and 1960, the Faculty of Architecture and Urban Planning of Sao Paulo (FAU-USP) had been a center of ethics and esthetics principles, guided by the master João Batista Vilanova Artigas, architect and urban planner known as a diffuser, an important professor and great leader of the modern movement in Brazil. The architect Jorge Caron (1936/2000) represented the second generation of the modern architect idealized by this group from FAU-USP. He worked as an architect and urban planner, educator, landscape worker, designer, scenographist, movie director and cultural producer. He was indoubtly an important professional, having worked intensely for developing a national culture. In this work, we analyze Jorge Caron professional carrier based on the recovery and the systematic study of his proposals. We identify the interlocutors, the conflicts and dialogs established in this context, aiming to reveal the choices and strategies also translated in his architecture.

Повний текст джерелаThis work proposes to confront two political, social and cultural phenomena that marked the twentieth century in Europe: the expansion of the old continent by colonial imperialism which started in the 1870s and the corporatist and fascist dictatorships of the interwar period. A comparative approach enables to understand the mechanisms by which representations of the Portuguese and Italian colonizations as they appeared in the colonial exhibitions of the period reflected and reinforced devices of domination exerted on metropolitan and colonial societies. Examining the aesthetic, historical and scientific motives of exhibitions, fairs and participations of Salazar's Portugal and Mussolini's Italy in international exhibitions, analyzing their manufacturing arrangements, and finally assessing the institutions, organizations and individuals involved in the process, permits to identify continuities and changes in the approach and interpretation of the colonial fact by each regime. These exhibitions were thus the result of evolving power relations in which the realities of the colonial ground were only one factor among others, as the balance of power in the fascist and salazarist states, struggles of influence between institutions, or inter-European rivalries in a particularly tense international context. Finally, the study of the presence of nationals of colonial territories permits to measure the racial dimension of these stagings of European domination

Повний текст джерелаAnálisis de la identidad minera en Lota (1800-2013), es una investigación que intenta buscar el origen, formación y consolidación de la identidad minera del carbón en la Octava Región, desde 1800 hasta 2013. Su objetivo es definir la identidad minera del carbón detectando los procesos históricos, sociales y culturales que participaron en la formación, consolidación y perduración de ésta tras el cierre de la industria carbonífera. ¿Cuál es la identidad minera del carbón? ¿Desde cuándo podemos hablar de ella? ¿Cómo se manifiesta en el tiempo? ¿Cuáles fueron los acontecimientos históricos que la consolidaron como tal? Son solo algunas de las interrogantes que intentaremos resolver. Uno de los temas centrales está dado por el impacto cultural local que provocó la inserción de la industria de extracción en un determinado territorio de Chile. Se analizarán también los fenómenos posteriores a su instauración que, de alguna forma, validaron la identidad minera y su perduración tras el cierre definitivo de los yacimientos de Lota. De acuerdo a lo anterior definiremos tres grandes períodos en este proceso: 1) antes de la llegada de la industrialización, 2) el período de su pleno funcionamiento y 3) la perduración de la identidad tras el cierre definitivo. Abordaremos el estudio con propuestas metodologías que nos entregarán una visión general por cada período, intentando describir: el capital cultural, económico, el espacio social, el grupo humano, las políticas públicas y la repercusión del acontecer nacional en lo local. Los resultados esperados son definir tanto el origen a la identidad minera del carbón de la Octava Región del Biobío, como detectar su consolidación y persistencia a pesar del cierre de la industria. Esta identidad marca un sentir común en la población de la cuenca de Arauco producto de ese largo proceso que intentaremos dilucidar. Los años de historia cultural común constituyen parte fundamental para las familias del sector; lo que explicaría el fracaso de la reconversión laboral, entre otras situaciones socio políticas existentes actualmente.

Dit probeer tot ’n begrip kom van presies hoe Carson “a brilliantly curated heap of scraps” verwerk tot ’n outonome kunswerk, “a thing that carries itself.” In die eerste gedeelte van die tesis word Nox as voorbeeld van ’n kunsboek (“artists’ book”) beskou. Nox se inhoud en voorkoms word gemeet aan die definisie en kenmerke van kunsboeke en binne die konteks van die geskiedenis van boekkuns as praktyk geplaas. Daar word veral gefokus op die visuele aard van Nox, die maniere waarop die boek verskil van meer konvensionele tekste, die selfbewustheid en selfrefleksie wat in die teks manifesteer en die eenheid van vorm en inhoud wat die outeur/kunstenaar bewerkstellig. Die tweede gedeelte ondersoek hoe vertaling op verskillende vlakke as proses in die skep van Nox funksioneer. Die fragmente en brokstukke waaruit die teks bestaan word deur middel van vertaling tot ’n eenheid gebind. Die proses van lewensbeskrywing word op metaforiese vlak as ’n soort vertaling gesien, wat parallel staan teenoor die letterlike vertaling van Catullus se “Gedig 101” wat op die bladsye van Nox plaasvind. Terselfdertyd verteenwoordig die wyse waarop ’n private objek (Carson se notaboek waarin sy die oorspronklike brokke byeengebring het) verwerk word tot ’n publieke kunswerk (die kunsboek Nox) ’n volgende vlak van vertaling wat die ander twee vlakke omarm en bevat. Deur middel van ’n proses van intersemiotiese vertaling skep Carson in die kunsboek Nox ’n weergawe van “Gedig 101”. Die manier waarop die gedig betekenis skep word in ander tekensisteme in die kunsboek nageboots. In die laaste afdeling word semiotiek aangewend as teoretiese raamwerk waarbinne ’n teks wat uit verskillende media saamgestel is, ondersoek kan word. In dié gedeelte word ’n stiplees van Nox onderneem om te demonstreer presies hoe Carson die fragmente en brokstukke verwerk om ’n samehangende eenheid te skep. Daar word aangedui dat die teks gelees kan word as ’n vertraagde, verskerpte en ontplofte vertaalhandeling wat uitdrukking en vorm gee aan menslike smart. Die bundel Afskrif bestaan uit gedigte wat die moontlikheid van oorspronklikheid ondersoek en op verskillende maniere kyk na replikas, afskrifte, kopieë en herskrywings.
ENGLISH ABSTRACT: This thesis is a study of Anne Carson’s book Nox. It investigates the form, aesthetic, process and composition of the text, and attempts to come to an understanding of the way in which Carson transforms a “brilliantly curated heap of scraps” into an autonomous artwork, “a thing that carries itself.” The first section of the thesis discusses Nox as an example of an artist’s book. The content and appearance of the book are measured against the definition and characteristics of artist’s books, before it is placed within the context of the history of bookwork as an artistic practice. The visual nature of the book, the ways in which it challenges conventions of bookmaking, its self-consciousness and self-reflexivity, as well as the author/artist’s means of creating unity between form and content are emphasised. The second section of the thesis investigates how translation is used at different levels in the process of creating the work. Translation is used as a way of drawing together the fragments and scraps from which Nox is essentially made. At a metaphoric level, the process of life writing is seen as a form of translation, which also runs parallel to the literal translation of Catullus’ “Poem 101” contained in the pages of Nox. At the same time, the transformation of a private object (Carson’s personal notebook in which she collected the original scraps) into an artwork for public consumption (the artist’s book Nox) represents a third level of translation, which embraces and contains the other two. Through a process of intersemiotic translation, Carson creates a version of “Poem 101” in her artists’ book that mimics the way in which the poem creates meaning. In the last section of the thesis, semiotics is applied as a theoretical framework to facilitate the reading of a text in which various media is present. A close reading of Nox is undertaken to demonstrate exactly how Carson goes about processing the fragments and scraps into a coherent unity. The close reading reveals that Nox can be read as a slow, intensified and exploded exercise in translation that gives expression to grief. The collection of poems entitled Afskrif consists of poems which question the possibility of originality and investigates replicas, photocopies, copies and rewritings in different ways.

Повний текст джерелаRegional outbreaks of western spruce budworms (Choristoneura occidentalis Freeman) have recurred at least three times in northern New Mexico since the early 1920's when the U. S. Forest Service first began systematic forest-pest surveys and documentation (Lessard 1975, U. S. Forest Service documents). The current outbreak was first noticed in a small area on the Taos Indian Reservation in 1974, and since then the defoliated areas have increased in New Mexico and Arizona to more than 370,000 acres of Federal, Indian, State and private lands (Linnane 1984). Losses in timber values can generally be ascribed to radial growth loss, height growth loss, topkilling, reduced regeneration, and mortality (Carlson et al. 1983, Fellin et al. 1983). A damage assessment project was initiated in 1978 and was aimed at obtaining measurements of some of these losses in budworm infested stands on the Carson National Forest, New Mexico (Holland and Lessard 1979). A large data base has subsequently been developed, including yearly measurements on topkilling, mortality, defoliation, and insect population changes (Stein 1980, 1981, Stein and McDonnell 1982, Rogers 1984). A growth assessment study was undertaken in 1982 to determine the feasibility of using dendrochronological methods to identify the timing of past outbreaks and to quantify radial growth losses associated with budworm defoliation (Swetnam 1984). Results of this work showed that three major outbreaks during the twentieth century were clearly visible in the tree-ring samples obtained from currently infested trees. The radial growth of host trees was corrected for age, climate and other non-budworm environmental effects, and then growth losses were computed as a percentage of expected growth (Swetnam 1984). Additional collections were obtained in 1984 in order to expand the scope of the radial growth study. The objectives included 1) assessment of a larger number of tree -ring samples, 2) comparison of radial growth losses between the two primary host species - Douglas-fir (Pseudotsuga menziesii) and white fir (Abies concolor), 3) comparison of radial growth losses between age classes, and 4) analysis of the relationship between yearly measurements of defoliation, insect populations and radial growth. This report summarizes the findings of the above analyses. Increment core samples from the 1982 collections are included here, therefore this report supersedes the earlier report (Swetnam 1984). Information is also presented on observations derived from the dated tree-ring series on the timing of occurrence of known and inferred spruce budworm outbreaks for the past 284 years (1700- 1983). This is the longest record of spruce budworm occurrence yet developed for western North America.
