Abstract:
Malgré leur surprenante diversité physique, les régions et les îles de la péninsule hellénique peuvent être classées en trois grandes catégories, formant trois zones aux caractères géophysiques bien différents : celui, au climat plutôt doux, du littoral et de ses vallées; celui de l'hinterland montagnard; et celui des plaines de Thessalie, de Macédoine et de Thrace. Au premier paysage correspondent les cultures et les produits traditionnels de la Méditerranée : la vigne, le vin et le raisin sec, l'olivier et l'huile d'olive. Au deuxième, l'économie de la montagne : les activités et les produits de l'élevage. Au troisième, les productions de la plaine : les céréales, le coton, le tabac, les agrumes. Une économie rurale aux traits méditerranéens, une autre aux traits balkaniques, une troisième aux caractéristiques mixtes.

Abstract:
L'indice pluviométrique mensuel proposé par le National Climatic Data Center (NCDC) est égal à la moyenne arithmétique des précipitations observées à certaines stations de la division climatique. Les différents problèmes d'homogénéité des données prises en compte par le NCDC pour le calcul de l'indice sont quantifiés pour la région climatique centrale de l'Oklahoma. Une amélioration de la méthode de calcul est proposée. Le calcul de ce nouvel indice utilise un nombre fixe de stations et fait appel à une méthode d'estimation des données manquantes. L'estimation des valeurs manquantes permet de disposer d'un jeu de données complet, ce qui augmente la représentativité de l'indice. Les moyennes mensuelles des valeurs absolues des différences entre l'indice NCDC et l'indice proposé sont comprises entre 6 % (mai) et 13 % (août) des précipitations moyennes et entre 9 % (novembre) et 24 % (août) des écart-types mensuels. Ces valeurs démontrent que les problèmes liés à la méthode de calcul d'un indice pluviométrique mensuel régional utilisée par le NCDC peuvent être importants. Les résultats de recherches sur la variabilité temporelle des précipitations utilisant un indice pluviométrique régional devraient être interprétés en connaissance de ces différences.

Abstract:
La zone hyporhéique est un bioréacteur pouvant influencer le fonctionnement biogéochimique des hydrosystèmes fluviaux. La quantification de son rôle vis-à-vis des flux d'eau et d'éléments dissous transitant dans l'hydrosystème de grande plaine alluviale a été réalisée par modélisation numérique. Le travail de modélisation s'appuie sur des données précédemment acquises sur les sites expérimentaux de Freienbrink (Allemagne), de l'Hers et de la Garonne (France). La démarche de modélisation a consisté à développer un modèle hydrodynamique couplant les équations de Saint Venant (2D) pour les écoulements de surface et les équations de Darcy-Dupuit pour le milieu poreux, ainsi qu'un modèle de transport réactif des formes dissoutes de l'azote minéral et de la matière organique. L'ensemble des conclusions souligne l'importance des échanges transitoires entre cours d'eau et zone hyporhéique qui favorisent le stockage de l'eau et l'activation des processus de dénitrification
The hyporheic zone is a bioreactor which can influence the biogeochemical functioning of fluvial hydrosystems. In this work, quantification of its role on water and solutes fluxes in hydrosystem of large alluvial floodplains was made by modelling approach. The proposed model was applied and validated using data previously measured on experimental sites of Freienbrink (Germany), Hers and Garonne (France). The complete model consists of two additional components: a hydrodynamic component (horizontal 2D Saint Venant equations for river flow and 2D Dupuit equations for hyporheic zone flow) coupled with a reactive solute-transport component for dissolved forms of mineral nitrogen and organic matter. The conclusions highlight the importance of transient exchanges between stream and hyporheic zone which facilitate water storage and denitrification processes activation

Les Européens attirés par les richesses de l'extrême orient, vulgarisées par les croisades, accessibles par la route de la soie ouverte par les Mongols, veulent se soustraire à la rapacité des caravaniers. Par Le Cap, Vasco de Gama mène le Portugal à l'Orient, et Magellan y guide les Espagnols en contournant l'Amérique du Sud. Anglais et Hollandais cherchent la route du Nord-Ouest. Les Français songent à une voie transcontinentale par "la Rivière de l'Ouest" et "la Mer de l'Ouest" entrevue par Verrazzano, tracée par des géographes dont Delisle. Cartier découvre le Saint-Laurent, Champlain prolonge jusqu'aux Grands Lacs. Sollicité par Lewis Cass, Margry distingue Pierre de La Vérendrye (1685-1749). Margry est surpris par cet audacieux personnage entraînant sa famille à la recherche de la "Mer de l'Ouest" ; renseigné par les Indiens et la carte d'Auchagah gravée par Chaussegros ; créant des postes du lac Supérieur au lac Manitoba, et à la Saskatchewan, génant la traite anglo-indienne à la Baie d'Hudson ; découvrant le réseau hydrographique du lac Winnipeg et des lacs adjacents, avec les rivières Winnipic, Saskatchewan, Rouge du Nord, son affluent l'Assiniboine, grossie de la Qu'Appelle et la Souris menant au Missouri, et chez les Mandans peints par Catlin ou vers les Bighorn. Il le voit subir avec constance les pires épreuves : dénigrement, mésestime du ministre, décès de son neveu, massacre du fils aîné et du Père Aulneau. Destitué, puis nommé capitaine et chevalier de Saint-Louis, rétabli commandant à la "Mer de l'Ouest", il obtient enfin la reconnaissance de ses qualités exceptionnelles. Il est admis par les historiens comme l'égal des Cartier, Champlain, Mackenzie, Lewis et Clark
Attrated by Far Eastern luxury reachable through the silk road open by the Mongols, Europeans wished to escape from greedy caravaneers. Vasco de Gama reached the Far East round the Cape of Good Hope, and Magellan reached it surrounding South America. The Dutch and The English sought the North-West road. The French thought about a transcontinental water way throught the "River of the West" and the "Western Sea", of which Verrazzano caught a glimpse, drawn by geographers among them Delisle. Cartier discovered the Saint-Lawrence River, Champlain extented the water way to the Great Lakes. Margry noticed Pierre de La Vérendrye (1685-1749) at the request of Lewis Cass. Margry was astonished by this bold man who dragged his family toward the "Western Sea", under informations picked of from Indians and from the map of Auchagah redrawn by Chaussegros ; building posts from Lake Superior to Lake Superior to Lake Manitoba, and on the Saskatchewan River, putting obstacles upon the Hudson Bay Indian's trade ; discovering the hydrographical net work of Lake Winnipeg and adjacent lakes, with rivers : Winnipic, Saskatchewan, Red from the North and its Assiniboin tributary swelled by the Qu'Appel and The Souris, which led to the Missouri River and the Mandans, and even to the Bighorn. He saw him suffer the worst hardships : defamation, little regards from his Minister, death of his nephew, and his first son and Father Aulneau slaughtered by the Sioux. After he was discharged, his appointement as captain and chevalier of the Saint-Louis Cross, and his restoration has commander to the "Western Sea" post, show recognition for his outstandingly gifted qualities. Historians consider him equal to : Champlain, Lewis and Clark. . .

Abstract:
This dissertation is a study of the Eastern Apache nations and their struggle to survive with their culture intact against numerous enemies intent on destroying them. It is a synthesis of published secondary and primary materials, supported with archival materials, primarily from the Béxar Archives. The Apaches living on the plains have suffered from a lack of a good comprehensive study, even though they played an important role in hindering Spanish expansion in the American Southwest. When the Spanish first encountered the Apaches they were living peacefully on the plains, although they occasionally raided nearby tribes. When the Spanish began settling in the Southwest they changed the dynamics of the region by introducing horses. The Apaches quickly adopted the animals into their culture and used them to dominate their neighbors. Apache power declined in the eighteenth century when their Caddoan enemies acquired guns from the French, and the powerful Comanches gained access to horses and began invading northern Apache territory. Surrounded by enemies, the Apaches increasingly turned to the Spanish for aid and protection rather than trade. The Spanish-Apache peace was fraught with problems. The Spaniards tended to lump all Apaches into one group even though, in reality, each band operated independently. Thus, when one Apache band raided a Spanish outpost, the Spanish considered the peace broken. On the other hand, since Apaches considered each Spanish settlement a distinct "band" they saw nothing wrong in making peace at one Spanish location while continuing to raid another. Eventually the Spanish encouraged other Indians tribes to launch a campaign of unrelenting war against the Apaches. Despite devastating attacks from their enemies, the Apaches were able to survive. When the Mexican Revolution removed the Spanish from the area, the Apaches remained and still occupied portions of the plains as late as the 1870s. Despite the pressures brought to bear upon them the Apaches prevailed, retaining their freedoms longer than almost any other tribe.

Full text
Abstract:
Dans certains phénomènes physiques modélisés par des EDP, les coefficients intervenant dans les équations ne sont pas des fonctions déterministes fixées, et dépendent de paramètres qui peuvent varier. Ceci se produit par exemple dans le cadre de la modélisation des écoulements en milieu poreux lorsqu’on décrit le champ de perméabilité par un processus stochastique pour tenir compte de l’incertitude sur ce champs. Dans d’autres cadres, il peut s’agir de paramètres déterministes que l’on cherche à ajuster, par exemple pour optimiser un certain critère sur la solution. La solution u dépend donc non seulement de la variable x d’espace/temps mais aussi d’un vecteur y = (yj) de paramètres potentiellement nombreux, voire en nombre infinis. L’approximation numérique en y de l’application (x,y)-> u(x, y) est donc impossible par les méthodes classiques de type éléments finis, et il faut envisager des approches adaptées aux grandes dimensions. Cette thèse est consacrée à l’étude théorique et l’approximation numérique des EDP paramétriques en grandes dimensions. Pour une large classe d’EDP avec une certaine dépendance anisotrope en les paramètres yj, on étudie de la régularité en y de l’application u et on propose des méthodes d’approximation numérique dont les performances ne subissent pas les détériorations classiquement observées en grande dimension. On cherche en particulier à évaluer la complexité de la classe des solutions {u(y)}, par exemple au sens des épaisseurs de Kolmogorov, afin de comprendre les limites inhérentes des méthodes numériques. On analyse en pratique les propriétés de convergences de diverses méthodes d’approximation avec des polynômes creux

Full text
Abstract:
Il est désormais bien reconnu que les activités agricoles sont à l'origine d'une grande part de la pollution des nappes souterraines par les ions nitrate. Le cas des plaines alluviales est particulièrement intéressant puisqu'elles associent la présence d'un sol riche et profond, très favorable à l'agriculture, et d'une nappe alluviale peu profonde. Dans ce travail nous nous sommes intéressés à deux types de plaine alluviale. La plaine alluviale de la rivière Alegria (Pays-Basque ; Espagne) représente le cas d'une nappe alluviale avec un cours d'eau de faible importance. La recharge de l'aquifère se fait alors principalement par l'infiltration et la percolation de l'eau à travers la zone non saturée du sol. Dans une telle situation les fuites de nitrate sous les parcelles agricoles influencent donc significativement les concentrations en nitrate de la nappe. La modélisation de deux situations culturales (une culture de pommes de terre en 1993 et une culture de betteraves à sucre en 2002) avec le modèle de culture STICS a permis d'une part de confirmer que les pratiques agricoles avaient un impact significatif sur l'évolution des concentrations en nitrate de la nappe, et d'autre part d'expliquer en partie la diminution des concentrations en nitrate de la nappe qui a été observé entre les études (1993 et 2002). La plaine alluviale de la Garonne correspond à une situation ou les concentrations en solutés de la nappe sont influencées par les échanges nappe-zone non saturée mais également par les échanges nappe-rivière. Le couplage des sorties du modèle STICS (drainage et concentration en nitrate) avec le modèle hydro-biogéochimique 2SWEM a permis de rendre compte de ces deux types d'interactions, et ainsi d'une part d'expliquer la répartition spatiale des concentrations en nitrate dans la nappe alluviale, et d'autre part d'évaluer l'impact de modifications des pratiques agricoles sur ces concentrations (notamment l'effet des Cultures Intermédiaires Piège À Nitrate)
It is now, well recognized that agricultural activities are responsible for an important part of the groundwater nitrate pollution. The case of the alluvial plains is particularly interesting because they associate the presence of a rich and deep soil, very favourable to the agriculture, and shallow alluvial groundwater. In this work we are interested in two types of alluvial plain. The alluvial plain of the Alegria River (Pays-Basque, Spain) represent the case of an alluvial plain with a small river. The recharge of the aquifer is mainly made by the infiltration and the percolation of the water through the not saturated zone of the soil. In such situation the nitrate leaching under the agricultural plots influences significantly the groundwater nitrate concentrations. The modelling of two crops (a potato crop in 1993 and a sugar beet crop in 2002) with the model the STICS soil-crop allowed on one hand to confirm that the agricultural practices had a significant impact on the evolution of the groundwater nitrate concentrations, and on the other hand to explain partially the decrease of the concentrations which was observed between the studies (between 1993 and 2002). The alluvial plain of the Garonne corresponds to a situation where the groundwater solutes concentrations are influenced by the exchanges between not saturated zone and the groundwater but also by the exchanges between groundwater and river. The coupling of the STICS model outputs (drainage and concentration in nitrate) with the hydro-biogeochemical model 2SWEM allowed to simulate these two types of interactions, and so, on one hand to explain the spatial distribution of the groundwater nitrate concentrations, and on the other hand to estimate the impact of modifications of the agricultural practices on these concentrations (notably the effect of the catch crop)

Abstract:
The interaction among water, sediment, landforms, and human environmental manipulation on the Northern Rio Grande has produced a distinctive assemblage of plants in the riparian (or near-channel) community. The fluvial landforms and the sediment of which they are composed are often not immediately visible in field investigations because of the dense cover of riparian vegetation. In aerial photography—the primary source of data for historical river-channel change and sedimentation- riparian vegetation is often the only aspect of the near-channel environment that is amenable to interpretation and mapping. Vegetation also provides information about the date of emplacement of the sediments on which it grows, information useful in tracking contaminants introduced into the system during known time periods. Vegetation communities therefore provide useful keys to identifying the distribution of near-channel sediments and the contaminants they contain. This chapter briefly reviews the origin and changes in riparian vegetation in the study area, including its connections with geomorphic systems. Almost all major rivers in the American Southwest have undergone considerable geomorphic and vegetation change since the early nineteenth century when channel margins were the sites of bogs, lakes, abandoned meanders (sloughs), and marshes. Most major rivers had broad, sandy channels with braided configurations and meandering low-flow channels. Even small tributaries had marshy areas created by beavers. The riparian vegetation originally evolved in association with frequent extensive flooding. Removal of the beavers, the development of gullies and arroyos, land-management schemes, changes in climate, and the construction of dams changed the streams into single-thread or compound channels that flooded less often. The Rio Grande’s recent history is typical of the larger region except for the extensive recent engineering works that restrict the active channel and flood plains. There are few detailed descriptions of the channel and riparian vegetation before major human intervention, but generally, most firsthand observers indicate that the Northern Rio Grande was broad and shallow, with meandering subchannels frequently altered by flooding. After channel migration, cottonwood, willow, and cattail colonized the newly exposed alluvial surfaces. Early in the twentieth century, the cottonwood groves near the river rarely developed trees more than about 10 m high before more changes in the channel destroyed them.

Abstract:
The water, sediment, landform, and vegetation systems of the Northern Rio Grande provide the environmental framework within which plutonium moves and is stored. Plutonium enters the Northern Rio Grande from two sources: atmospheric fallout and releases from operations of Los Alamos National Laboratory that enter the main stream by transport through Los Alamos Canyon. This chapter describes the nature and timing of plutonium loading in the river’s sediment system as a means of identifying those years when sedimentation is likely to have accumulated those deposits with the highest concentrations of plutonium. This chapter also discusses plutonium in river water, sediments in transit, and sediments deposited along and stored along the channel, as well as the various mean values of plutonium concentrations found in the region of Los Alamos. The review includes plutonium in the regional environments around Los Alamos, including the compartments of river water, active sediments, flood-plain deposits, and reservoir deposits, as well as the plutonium concentrations in the sediments of Los Alamos Canyon. Most of the plutonium in atmospheric fallout is from the testing of nuclear weapons. Five nations have detonated a total of 484 nuclear devices in the atmosphere, 466 with known dates. These explosions have injected plutonium into the general atmospheric circulation, resulting in a global distribution of fallout as the material returns to the surface. There are three types of fallout: local, tropospheric, and stratospheric. Local or early fallout arrives within a day of the detonation and consists of particles 100 to 200 microns in diameter (fine sand) transported in the lower atmosphere and deposited within several hundred kilometers of the site of the explosion. Finer particles travel greater distances and disperse over greater areas. Tropospheric fallout arrives within a month of the detonation and consists of particles less than 100 microns in diameter (mostly silt size), transported in the lower atmosphere. The global atmospheric circulation transports tropospheric fallout around the world in a band about 30 degrees latitude wide, centered on the site of the explosion. Most of the tropospheric fallout delivers plutonium to the earth’s surface in precipitation, with only about 10 percent occurring as dry fall.

Abstract:
Ruled from Mexico City for about a century longer than they have thus far been from Washington, New Mexico and Arizona lie in what English speakers generally term ‘the Southwest’. I follow that usage here, even though calling them the ‘Northwest’ (of first colonial New Spain and then an independent Mexico) would, for this chapter’s purposes, be more accurate, as well as emphasizing that the cultural area to which their Indigenous inhabitants belonged extended across modern Chihuahua, Coahuila, Durango, Sinaloa, and Sonora. Together with the Southern Plains, to which trade links intimately tied it before and after Spanish arrival, the Southwest constituted the cradle within which the first Horse Nations of North America took shape. I start by highlighting key aspects of the two regions’ ecologies and prehistories. Next, I look at the horse’s impact on the Southwest’s settled farming peoples, particularly the Pueblos, many of whom came under Spanish rule after 1598. Its take-up by their Athapaskan-speaking neighbours, the Apache and Navajo, gives us our first view of how more mobile societies understood and used the horse, including—in the Navajo case—the development of a distinctive pastoralist way of life. Attention then turns to the Comanche, another pivotal player in the horse’s expansion across western North America, for whom it altered not just how they secured food, but also their social organization and entire economy. Trade—especially trade in horses—was critical in this, and so I end by examining the horse’s arrival among some of the Comanches’ trade partners, the village communities of the eastern edge of the Southern Plains, an area to which Native farmers-with-horses from the American South moved, and were forced to move, in the early 1800s. The Southwest is one of the driest parts of North America (Plate 4). Its climate is also strongly seasonal, with cold winters and hot summers. Major drainages are few: the Colorado in the west and northwest, southern Arizona’s Gila, the Río Grande, which snakes south through New Mexico and then along the present Texas/Mexico border, and the rivers draining into the Gulf of California from Mexico’s rugged Sierra Madre Occidental.

Abstract:
Downstream from White Rock Canyon and the reaches discussed in Chapter 9, the Rio Grande takes on a different character because of the presence of Cochiti Dam at the lower end of the canyon. From that point downstream, the river’s present appearance and behavior reflect the influence of the dam, which was closed in 1973. Although the channel has become narrower throughout the length of the Rio Grande since the 1930s, this change is most pronounced south of Cochiti Dam. Downstream from the Los Lunas representative reach (which ends near Bernardo), the character of the Rio Grande changes radically. Immediately below Bernardo, the Rio Puerco joins the main river, bringing with it a huge load of sediment. The Rio Grande Valley becomes much wider below Bernardo, and the twentieth-century narrowing of the channel, aided by engineering works, is even more pronounced than in upstream areas, and the vegetation community is dominated by tamarisk. The final three representative reaches discussed in this chapter share the features of great valley width, extensive channel changes, and widespread impacts of engineering works. The Peña Blanca reach, a 5-km channel section, represents conditions common along 40 km of the Northern Rio Grande between Cochiti Pueblo (site of Cochiti Dam) and the confluence with the Jemez River. The river passes Peña Blanca, a settlement based on irrigated agriculture dating from the early nineteenth century. The reach is typical of the conditions in a portion of the river where the flood plain is several times the width of the channel and where the channel has been exceedingly unstable. The reach is also instructive concerning the results of levee construction (in 1953) and dam closure (in 1973). The behavior of the channel in the Pena Blanca reach between the early 1940s and about 1990 has consistently included locational instability and progressive adjustment from a broad-braided configuration to a narrow, straighter alignment. In the 1940s, the channel was wide and unstable, with numerous major and minor threads, but the gradual reduction in water yield and radical reduction in the annual flood peaks resulted in the progressive isolation and closure of secondary channels.

Part II of the Housing Grants (Construction and Regeneration) Act 1996 (‘the 1996 Act’), as amended, requires all construction contracts to have an adjudication procedure that complies with s108: see s108(5). The same section makes plain that if the construction contract in question does not contain adjudication provisions that comply with s108(1)–(4), then the Scheme for Construction Contracts will apply. It is therefore envisaged that the construction contract will include its own adjudication provisions.

Abstract:
On a summer morning when the breeze blows cool, it is easy to re the lakes and sagebrush-covered glacial plains of Wyoming’s Jackson Hole sit at nearly 7,000 feet elevation. Yet the altitude of this gorgeous valley is diminished by the view to the west: The precipitous east front of the Teton Range towers above the valley floor, with 13,770-foot Grand Teton and other rugged, snowclad peaks catching the first golden rays of daybreak. This is one of the most spectacular mountain vistas in America. Whether at chill dawn, in glistening light after a torrential afternoon thunderstorm, or during summer evenings when the sun descends behind the lagged Tetons, it is a view that brings solace and peace. Yet the serene splendor of Grand Teton National Park belies a hidden fury. It is not volcanism, which is concealed beneath the gentle pine-covered Yellowstone Plateau to the north. Instead, this defiant topography was born of seismic disaster as the Teton fault repeatedly and violently broke the earth, producing a few thousand magnitude-7 to -7.5 earthquakes during the past 13 million years. During each major jolt, Jackson Hole dropped downward and the Teton Range rose upward, increasing the vertical distance between the valley and the mountains by 3 to 6 feet and sometimes more. Now, after 13 million years of earthquakes, the tallest peaks tower almost 7,000 feet above the valley floor. Actual movement on the fault has been even greater. Jackson Hole dropped downward perhaps 16,000 feet during all those earthquakes. Rock eroded from the Teton Range and other mountains by streams and glaciers filled Jackson Hole with thousands of feet of sediment, disguising how much the valley sank. Combine the uplift of the mountains and the sinking of Jackson Hole, and the best estimate—although still plagued by uncertainty—is that movement on the Teton fault has totaled 23,000 feet during the past 13 million years. That is a tiny fraction of Earth’s 4.6-billion-year history. Consider the effects of repeated episodes of mountain-building during eons before the Teton fault was born: The oldest rocks high in the Teton Range are 2.8-billion-year-old gneisses and schists and 2.4-billion-year-old granites.

Abstract:
La durée des traitements orthodontiques est une des plaintes principales des patients en pratique orthodontique, en particulier chez les patients adultes. Le traitement orthodontique chez l’adulte doit s’adapter à des particularités comme l’absence de croissance et l’augmentation des atteintes parodontales. La corticotomie alvéolaire se définit comme une lésion chirurgicale contrôlée de l’os alvéolaire en vue d’induire un remodelage osseux accéléré, responsable localement d’une ostéopénie transitoire facilitatrice du déplacement dentaire. Le recours aux corticotomies alvéolaires permettrait d’accélérer le déplacement dentaire par un facteur 3 ou 4 (2) avec des suites opératoires souvent moins importantes qu’une avulsion de prémolaire , en particulier dans les nouvelles approches mini-invasives. La piezocision permet la correction orthodontique de malocclusions sévères sans présenter les inconvénients des approches chirurgicales extensives et traumatiques des corticotomies alvéolaires classiques. Elle offre un temps chirurgical réduit, des suites post-opératoires minimales, une grande tolérance chez les patients ainsi qu’un parodonte amélioré. (3) Nous présentons une revue de la littérature afin d’évaluer l’efficacité de l’ostéotomie inter alvéolaire par piezocision sur l’accélération ou la facilitation des déplacements dentaires comparée au traitement orthodontique classique. La recherche des données de la littérature a été réalisée sur la base de données pubmed. Les études ont montré que les corticotomies par piezocision favorisent et accélérent les déplacements dentaires avec peu de complications associées. (4) Nous avons retrouvé peu de lésions parodontales et dentaires d’origine iatrogènes. Peu d’études comparatives avec le traitement orthodontique conventionnel ont étés retrouvées mais elles affirment que l’ostéotomie interalvéolaire diminue le temps de traitement orthodontique global de façon significative. Les corticotomies interalvéolaires par piezocision ont un ratio bénéfice risque très favorable et se montre être une solution thérapeutique efficace dans le traitement orthodontique de l’adulte.

Abstract:
In a two-year program, seventy-eight specimens of PVC pipe with and without adhesive socket joints were tested in a four-point bending apparatus. Internal pressures were varied from atmospheric pressure (0 psig) to the rated internal pressure of 280 psig. Results of the plain pipe are compared to pipe with joints. All testing was done using a special apparatus developed to accommodate the large deformations required for fatigue testing of PVC pipes. This apparatus is described as well as the test results. Both strains and stresses are plotted against cycles-to-failure. Finite element elastic models of the socket joined specimens were analyzed to establish the areas of stress concentration and to explain the observed failure modes. Phase 1 testing indicated that the pipe internal pressure might have a significant effect on fatigue life. Joined pipe specimens with no internal pressure were weaker in bending fatigue than pressurized pipe. As a result, the internal pressure was systematically varied between 0 psig and the rated pressure 280 psig. Results of Phase 2 testing revealed a dependence on internal pressure. Also, the effects of an adhesive primer and roughening of the pipe surface on joint fatigue strength were also studied. Strain rate is known to exert a profound influence on the fatigue behavior of thermoplastic polymers. This effect has not been systematically studied and remains an unknown. This research was supported by two grants from the Pressure Vessel Research Council. Additional details of the research are compiled in the Welding Research Council (WRC) Bulletin 445.

Abstract Objective and scope This paper aims to establish that proper resource management and governance within the Nigerian oil and gas industry, more specifically, her local participation policy, which focuses on adequately addressing the social and economic concerns of the host communities in oil producing regions of Nigeria, particularly in the Niger Delta, will ultimately lead to more secure and sustainable economic development and a more attractive investment climate for Nigeria. Methods Procedure, process This research study will employ an analytical approach, more specifically qualitative analysis, in analyzing the interplay between the various factors which have birthed low oil and gas productivity in the Niger delta region of Nigeria and how proper application of Nigeria's local participation policy can influence the circumstances and yield positive result. The research study will rely heavily on available literature and legislative enactments, as well as available case law on the issues concerned. The primary sources in the collection of materials for this paper will comprise of journals, books, and articles which address the relevant research questions guiding the scope of this paper. Results, Observation, conclusion Nigeria's local content policy, just like many other governmental policies in Nigeria, has been criticized as being vulnerable to corruption as a result of the manifest lack of transparency in the Nigerian oil and gas industry, and local content has already been labelled as a potential victim of capture as a result of this dearth in transparency. It is imperative that the broad discretionary powers granted to the local content monitoring board, and the minister of petroleum by the provisions of the Nigerian Oil and Gas Industry Content Development Act, be utilized in a manner devoid of parochial ethnic sentiments or political interest, in order for Nigeria to properly take advantage of the economic development benefits provided by the proper implementation of local content policy. The long term benefits of local content policy such as technology transfer, long term fiscal incentives, and the growth of local commerce and industry, will go a long way in setting Nigeria on a plain path to sustainable economic growth and better resource management. It is important that the Nigerian government play its role in driving local content policy by facilitating Nigerian enterprises to take active part in the local content programs, as well as keep tabs and monitor the effectiveness of local content policy in achieving its targets. New or additive information to the industry Proper implementation of Local Content policy in Nigeria will be beneficial, not just for the host communities but for the rest of the country, as well as for all investors in the Nigerian oil and gas industry, by providing thousands of employment opportunities for the locals, as well as providing a much needed technology transfer which will result in a structural transformation of not just the local manufacturing industries in Nigeria but the entire Nigerian oil and gas industry as well; thus addressing a major aspect of the social and economic concerns of the local people, and also giving Nigeria's economy a much needed boost towards achieving sustainable development in her natural resources sector.
