Full textAbstract:
The article presents the goals and the structure of the database "Parceling and Building System of Moscow Bely Gorod in the 18th century”, created within the framework of the project "Spatial reconstruction of the historical landscape of Moscow Bely Gorod in the 16th - 18th centuries (with the use of modern information technologies)". The database was created in MS Access DBMS and accumulates text and graphic sources characterizing parceling, planning and development of the eastern part of Moscow Bely Gorod in the 18th century as well as urban planning and personal information obtained from the analysis of these sources. The database is the basis for creating spatial 3D reconstruction and one of the main components of the geographic information system being developed. The database as a tool for systematizing text and graphic historical information is a new method to study and reconstruct historical landscapes. It presents sources that served the basis for the reconstruction in an organized way thus greatly simplifying the verification of conclusions and results of the study. The article describes the main objects of the database (historical sources including graphic, town-planning objects (driveways, households, buildings) and personalities (owners of courtyards)) and their interconnections and methods of data formalization. The article pays special attention to the features associated with the processing of property owners' biographical and genealogical information.

Full textAbstract:
The article summarizes the results of a two-year study of the issues related to the virtual reality and augmented reality technologies use to virtually reconstruct Moscow Bely Gorod in the 16th-18th centuries. The authors describe mathematical methods, software and hardware which grant access to the historical reconstruction of historical urban landscapes. An important feature of the reconstruction is the source verification module which was used to construct three-dimensional models of the landscape, buildings and the general scenery. The article names the basic principles which the verification module and its interface are based on and considers some optimum problems solved when constructing the interface. The project uses a hybrid motion tracking system as a combination of optical and inertial data. The archival sources used in the reconstruction process are presented in the virtual environment by means of a 3D graphical user interface for the virtual reality. The information displayed is generated from the database of historical sources which includes information about the urban development and individual buildings of Bely Gorod, their parts, location, purpose, owners and construction date. The database contains both text and graphic historical sources. The results obtained also include new algorithms, software and hardware systems as well as the experiment results.

Full textAbstract:
The article sets a problem focusing on how to optimize the order of 3D user interface for virtual reconstruction of Moscow historical center landscape in the 16th-18th centuries. To work with the interface a virtual reality headset, a motion tracking system and an eye-tracker were integrated. Spatial representation of the historical reconstruction is accompanied by a specialized interface that allows one to access the source database. The authors introduce a criterion that provides for estimating the optimum order of interface elements in the virtual space. The problem is handled in case there are unknown factors such as the size of user's hands, deviations in the position of an interactive object and restrictions related to the disposition of interface elements. The article sets the general problem and solves some internal problems related to the construction of acceptable multiple dispositions of interface elements and the modeling of eyesight movement from one interface element to another. The article is the first to suggest an algorithm to numerically optimize the interface in 3D virtual space modeling the relief and historical buildings in the center of Moscow. It provides for user’s movement and gives access to historical sources which are the basis for virtual reconstruction of the heritage understudy.

Full textAbstract:
Virtual reconstruction of an urban historical landscape over a relatively large area requires the reconstruction of historical land surfaces. To solve this problem one needs to obtain a detailed spatial data on the Earth surface elevation for a certain historical period as well as the information about the way it changed over time. The reconstruction can be performed using different software. One of the convenient options is to use geographic information systems (GIS) since this approach assumes work with georeferenced data “by default” thus providing for easier combinations with other reconstruction components. The article describes the creation of digital relief models (DRMs) of the eastern part of Moscow Bely Gorod reflecting the state of the land surface in the 16th, 17th and 18th centuries via GIS software (MAG, SAGA, QGIS). Input data for this research are contours from 1:2000 topographic plans and generalized materials of archaeological sources. Using this basis as well as GIS analysis methods, three gridded DRMs (one for each epoch) have been constructed. These DRMs are suitable for use within the GIS environment and for export to other software.

The article studies a part of Moscow's historical center within Bely Gorod boundaries and is written as a part of the project aimed at creating a 3D-reconstruction of the historical landscape and the city layout in the 1760s-1770s. The authors create a map reconstructing the natural relief in the 14th century and the earth surface in the 1760s-1770s on the basis of archaeological data on the surface depth that preceded the urban life (the 14th century) as well as geological drilling data. The most difficult task was to reconstruct the landforms of the Rachka river valley which is now almost completely covered with a cultural layer. To solve this problem, the map underwent a geological and morphological examination by comparing it with the valley of the river – a natural analogue. The resulting digital reconstruction map of the river valley was verified by overlaying the buildings shown on the instrumental plans of the 18th-19th centuries and corrected. The research results are a series of schemes where the earth surface similar to that in the 14th century is shown by means of elevation contours and a separate map of the Rachka river historic bed. When comparing various materials, contradictions and inconsistencies were revealed that cannot be resolved using the data currently available, but the authors think that a detailed workflow presentation is sure to provide for completing and correcting the reconstructions presented in the article.

Full textAbstract:
Important considerations when designing a V-ribbed belt drive for maximum power transmission and service life are discussed. Owing to different pulley diameters and wear of the belt, the wedge angle of the belt changes and the pressure distribution between belt and pulley differs. In this paper a method for calculating the wedge angle of the belt as a function of curvature is presented. Calculations show that the pressure distribution depends strongly on pulley diameter. Moreover, the pressure distribution between the belt and the pulley is shown to affect the torque capacity in a drive to a large extent.

Full textAbstract:
Thesis (MSc)--Stellenbosch University, 1989.ENGLISH ABSTRACT: The Ceres Syntaxis comprises that part of the Cape Fold Belt Syntaxis that lies north of the Worcester Fault. Most of the area consists of folded Cape Supergroup (primarily Witteberg Group) rocks. Fold styles of all fold trends are essentially the same. However, different multilayer rheologies led to the development of either sinusoidal or kink-like fold geometries in different parts of the cover sequence. The character of Witteberg sediments led to the development of large megakink folds and peculiar fold zones in this part of the sequence. Fold trends in the Ceres Syntaxis vary between NW-SE, NE-SW and E-W. The southern part of the area is dominated by the NE-SW trend, with the NW-SE trend being only important in the west. Interference between these two trends only exists in the Witteberg Group, where it occurs as crossing linear fold zones and conjugate, intersecting kink folds . Cross-folding relationships in the north-eastern part of the Ceres Syntaxis indicate that the area had been affected by two contemporaneous, orthogonally opposed compressions that worked simultaneously in different parts of the multilayer. Differences in the magnitude of strain, or in the local timing of fold initiation, produced local refolding or transecting relationships. The microfabric of Witteberg sandstones suggests deformation under conditions of low temperature and pressure, as well as low strain rates. Some microfabrics also indicate that substantial buckle shortening occurred while the Middle and Upper Witteberg beds were still unlithified. Isotopic dating of Cedarberg shale from both main trends did not yield unequivocal results, mainly due to the deformatio~al intensity. The positioning of the Cape low Fold Belt Syntaxis was strongly influenced by basement tectonic grain and basin floor relief. The NW and NE fold trends formed on a heterogeneous basement that resolved the stress configuration into components which external . acted simultaneously towards the north-west and north-east. Ecca and Beaufort Group sedimentation patterns in the western Karoo corroborate the above findings.
AFRIKAANSE OPSOMMING: Die Ceres-sintaks beslaan daardie deel van die sintaks van die Kaapse Plooigordel wat noord van die Worcesterverskuiwing Ie. Die gebied bestaan grotendeels uit geplooide gesteentes van die Supergroep Kaap (hoofsaaklik Groep Witteberg). AIle plooirigtings openbaar dieselfde plooistyl. Reologiese verskille in'die rnultilaehet egter gelei tot die ontwikkeling van of sinusoidale ~f knikvorrnigeplooie in verskillende dele van die dekgesteentes. Die Wittebergsedirnente se aard het veroorsaak dat rnegaknikkeen eienaardige plooisones in hierdie deel van die opeenvolging ontstaan het. Plooirigtings in die Ceres-sintaks wissel tussen NW-SO, NO-SW en O-W. Die NO-SW plooirigting oorheers in die suidelike deel van die gebied, terwyl die NW-SO plooirigting eintlik net in. die weste belangrik is. Interferensie van hierdie twee.hoofrigtings korn slegs voor in die Groep Witteberg, waar dit as dwarssnydende lineere plooisones en snydende, konjugerende knikke aanwesig is. Onderlinge verhoudings tussen kruisplooie in die noordoostelike Ceres-sintaks, toon dat die gebied beinvloed is deur twee gelyktydige drukspannings wat reghoekig op rnekaar ingewerk het, sorntyds in effens verskillende dele van die rnultilaag.Verskille in die spanningsbedrag en tydsberekening het lokale herplooiing of dwarssnydende strukture veroorsaak. Die mikrornaaksel van die Wittebergsandsteen toon dat die vervorming onder lae temperatuur- en druktoestande, tesame met 'n lae vervorrningsternpo, plaasgevind het. Die rnaaksel toon ook aan dat heelwat buigplooiing plaasgevind het terwyl die Middel- en Bo-Witteberglae nog ongekonsolideer was. Isotopiese datering van Sederbergskalie afkornstigvan die twee hoofplooirigtings, het weens die lae vervormingsintensiteit swak resultate gelewer. Die posisie van die sintaks van die Kaapse Plooigordel, insluitende die van die Ceres-sintaks, is sterk' belnvioed deur die tektoniese grein en re~i~f van die vloergesteentes. Die heterogene vloer waarop die NW en NO plooie gevorrn het, het daartoe gelei dat die eksterne spanningsopset verdeel is in kornponentewat gelyktydig na die noordweste en noordooste gewerk het. Sedirnentasiepatrone in die Groepe Ecca en Beaufort ondersteun bostaande afleidings.

Specific characteristics of single heritage constructions pose a challenge at the moment of the formulation of a judgement on the preservation state and safety of the object. In Italy, the guidelines on assessment and reduction of seismic risk to heritage constructions have provided a procedure for gaining an adequate level of knowledge of masonry constructions. Such operative methodology is presented as a path made of many aspects that, at different levels and from many viewpoints, should bring together a detailed qualitative and quantitative knowledge of the artifact under analysis. Knowledge steps include the search for documents and information from various sources, visual inspections, surveys and non-invasive diagnostic approaches, structural numerical modelling. Nevertheless, these guidelines are necessarily a generic document and cannot detail many practical aspects so that the professional dealing with real cases has to rely on extensive knowledge and experience. This is particularly true in the case of peculiar typologies of constructions, such as ancient masonry towers, which – due to their geometry - present extra problems of accessibility, inspection and survey.
This thesis looks at a number of medieval masonry towers with steeple masonry spires located in Piacenza and Ravenna, Italy, to test on-site a multidisciplinary, coherent facts-finding path that keeps into account the characteristics and problematics of the single constructions in order to reach a reliable evaluation, drawing from the examination of the collected info and produced data. At the same time, this thesis aims to consolidate the author’s knowledge about the most correct choice and procedural application of various techniques according to the specific aims, in view of her professional future, keeping in mind both the engineer’s viewpoint of building safety and the architect respect for the heritage value.

This dissertation studies the Good inside Plato’s Symposium. We chose this theme because of the concerns that came out of Plato’s dialogues when, in them, it was not possible, at least not clearly, to determine the meaning of Good. On the contrary, its meaning was not fully explored (as it is seen in the “Book VI” of the Republic, in which the character of Socrates diverts from the subject itself and moves on to discussing the son of the Good, the Sun). Because of this concern this research found a new angle to explore what that meaning could be inside Plato’s Symposium. Therefore, we study the meaning of Good as we dwell on Agathon’s paradigmatic character, as it receives the name agathon, the Good. Plato gives us clues in order to start an investigation on the character himself, such as: its name, its household, the order of the dialogues, the parts of his speech etc. The ways for our search about the meaning of the Good originate from a research on the concept of love (ti metaxy, daimon) and beauty (kalos), as all of them are intertwined, clarifying what love and beauty are, and they are connected explicitly inside the dialogue in Plato’s Symposium (203c), and this suggests a way for us to enlighten the meaning of the Good. This research has a phenomenological approach, as it favors most of Heidegger’s ideas. We opted by Heidegger because this contemporary philosopher is the most crucial one for our clarification of the Good, as in many studies concerning the Greek terms, mainly when talking about agathon, he presented the interpretative way that we needed in order to achieve a proper understanding on the meaning of Good through Agathon’s character. By studying the Love inside Plato’s Symposium this investigation concludes that he is an intermediate (203a). As it is possible to notice in our research the term ti metaxy brings with it the meaning of something “that is inbetween”, intermediating a passage. Another term by which Love is called is Daimon: “the one that makes everything bright and clear”. Love as the one that brings clarity. Beauty is connected to it because, based on our studies, it is “what is brought upon” by Love (203c). We understand that this is how Love originated Beauty as what appears. And, as for the Good, we see as justified in this dissertation, based on a Heidegger’s phenomenological study (he returns to the term agathon in its Greek meaning), that this concept is unveiled as “pure possibility, offering, support for something to happen”. When taking this path directly to Agathon’s character we notice, at last, that it occupies this position inside the Symposium by undertaking exactly the role of the Good, as it was the one that offered the possibility and the support so that the Love logos and the Beauty manifestation could take place in its household. Good as possibility, as the reader himself will be able to notice after going through all of our research in this dissertation, was exposed in that character. However, without a proper investigation approach, as the phenomenology, we would not be able to achieve these conclusions, and we would be looking at the character as a simple scenic game inside Plato’s Symposium.
Essa dissertação se ocupa do tema do Bem. A decisão por esse tema resultou da inquietude surgida dos diálogos platônicos quando, neles, não era indicado, ao menos explicitamente, o sentido do Bem, mas, ao contrário, havia esquivas de explorá-lo (como se observa no “Livro VI” da República, no qual a personagem Sócrates desvia o assunto do Bem e passa a falar do filho do Bem, o Sol). Partindo da referida inquietação pela busca do sentido do Bem, o presente trabalho encontrou um novo viés para explorar o que poderia ser tal sentido, no âmbito do diálogo O Banquete, de Platão. Assim, julgamos poder entrever o sentido do Bem a partir da figura paradigmática de Agatão, pois tal personagem conceitual carrega o nome agathon, o Bem. Platão nos dá vários indícios para começarmos uma investigação da personagem, como: seu nome, sua casa, a ordem dos diálogos, as partes de seu discurso etc. Os caminhos para essa busca do sentido do Bem partem inicialmente de um estudo dos conceitos do amor (ti metaxy, daimon) e da beleza (kalos), pois os três conceitos encontram-se interligados, elucidando o amor e a beleza, que possuem ligação explícita no diálogo O Banquete (203c), favorecendo, assim, o encontro com um caminho de clarificação para o sentido do Bem. A pesquisa que aqui apresenta seus saldos valeu-se de um enfoque fenomenológico, tendo privilegiado muitas das posições heideggerianas. A opção por Heidegger se deveu ao fato de este ser o filósofo contemporâneo mais decisivo para a nossa clarificação do Bem, pois, em diversos estudos dos termos gregos, sobretudo sobre o agathon, esse nos acenou o caminho interpretativo que precisávamos para chegar ao sentido do Bem por meio da personagem Agatão. Ao estudar o amor no diálogo O Banquete, a presente investigação conclui que ele é um intermediário (203a). Como se pode ver ao longo de nossos movimentos de exposição, o termo ti metaxy carrega o sentido de ser algo que “está entre”, intermediando uma passagem. Outro termo pelo qual o amor é chamado é daimon: “aquele que faz brilhar e aparecer.” O amor como tal é aquele que traz o aparecer. A beleza se liga ao amor porque, a partir dos nossos estudos, ela se mostrou como “aquilo que aparece” do amor (203c). Compreendemos que é assim que o amor faz nascer a beleza como o aparecer. E, quanto ao Bem, julgamos poder sustentar nessa dissertação, apoiados num estudo fenomenológico de Heidegger (este que retoma o termo agathon em seu sentido grego), que tal conceito é desvelado como a “pura possibilidade, doação, suporte para que aconteça algo”. Ao levarmos esse sentido diretamente à personagem Agatão, percebemos, enfim, que ela esteve no diálogo ocupando justamente esse papel do Bem, sendo a que doava a possibilidade e o suporte para que ocorresse o logos do amor e o aparecimento da beleza em sua casa. O Bem como possibilidade, como o leitor poderá conferir após acompanhar todo nosso movimento de exposição nessa dissertação, estava implicitamente caracterizado naquela personagem. Entretanto, sem um método de investigação adequado, como a fenomenologia, não chegaríamos a estes saldos, e permaneceríamos mirando a personagem como simples jogo cênico do diálogo platônico.

Full textAbstract:
De nombreux critiques se sont penchés sur le caractère fantastique des romans d’Iris Murdoch, d’autres ont évoqué la notion du bien. Nous avons voulu dans cet écrit mettre en relation les deux notions et montrer qu’à travers le fantastique Iris Murdoch conduit son lecteur sur le chemin du bien dans cinq romans : The Bell, A Severed Head, The Italian Girl, Bruno’s Dream et Jackson’s Dilemma. Dans une première partie, après avoir proposé quelques définitions du fantastique, nous avons relevé dans le texte murdochien tous les éléments qui nous permettent de lui apposer cette étiquette. Par l’étude de l’illusion d’optique, nous avons pu confirmer que le fantastique prend sa source dans une fissure du réel et fait sourdre un monde où règnent peur, doute, rêve et folie. Nous avons, par la suite, analysé les symboles spécifiques du genre. Dans une deuxième partie nous avons examiné le rôle du lecteur dans les écrits de la romancière et tenté de comprendre en quoi la notion de fantastique pouvait influencer le sens de sa lecture. Dans une dernière partie nous avons établi qu’Iris Murdoch s’appuie sur l’aspect fantastique et inexplicable de la nature humaine pour orienter son lecteur vers le chemin du bien. La contingence à laquelle Iris Murdoch est particulièrement attachée, c’est-à-dire l’acceptation que tout ne peut être maîtrisé, force le lecteur à reconnaître que son destin lui échappe. Dès lors il lui est possible de lâcher prise et de ne plus mettre en avant un ego aveuglant. Il devient un homme humble capable d’un amour altruiste qui l’entraîne vers le bien où se réunissent la mort, l’amour et la littératureA number of reviewers have dealt with the fantastic character of Iris Murdoch’s novels, others have mentioned the Good. In this study we have aimed at linking both notions to show, in five of her novels: A Severed Head, The Bell, The Italian Girl, Bruno’s Dream and Jackson’s Dilemma, that through the ‘Fantastic’ Iris Murdoch leads her reader on the way to the “Good”.In the first part, after giving a definition of the word ‘fantastic’ we have selected all the elements that point towards the fantastic features in Iris Murdoch’s writings. Starting with the optical illusion, we have shown that the ‘Fantastic’ originates from a break in reality which gives birth to fear, doubt, dream and madness. We have then analyzed the symbols that characterize the genre. In the second part, we have examined the role of the reader in Iris Murdoch’s novels and we have tried to understand in what way the ‘Fantastic’ could influence readers. In the last part we have shown that Iris Murdoch relies on the “Fantastic” and the unexplainable aspect of human beings to lead her reader on the way to the “Good”. Contingency- that is admitting that not everything can have an explanation- which Iris Murdoch sees as of paramount importance, forces the reader to realize that he cannot master his destiny. Therefore the reader cannot do anything other than let go and stop putting forward a blind ego. He or she then becomes a humble man, able to feel an altruistic love that will take him or her on the way to the Good in which death, love and literature are connected

"Provenance of the Neoproterozoic to early Palaeozoic successions of the Kango Inlier, Saldania Belt, South Africa." Thesis, 2009. http://hdl.handle.net/10210/2437.
Full textAbstract:
M.Sc.The configuration of the supercontinent Rodinia, at the end of the Mesoproterozoic to the beginning of the Neoproterozoic (1100-750 Ma), and its subsequent break up into cratonic fragments that would later result in the formation of Gondwana (Early Palaeozoic), is still not completely understood. This is largely due to ambiguity surrounding relationships between cratons, craton evolution and timing of significant tectonic or sedimentary events. Particular to this study is the evolution and palaeogeographic history of the Kalahari Craton and a comprehensive provenance analysis of Neoproterozoic to early Palaeozoic clastic sedimentary rocks from the Kango Inlier (Saldania Belt, South Africa). This includes the Cango Caves and Kansa Groups as well as the Schoemanspoort and the adjacent Peninsula Formation (Table Mountain Group, Cape Supergroup). A well established lithostratigraphy, in addition to recent establishment of age constraints by UPb zircon dating and microfossil evidence, allowed for strategic sampling with the objective of gaining insight to the crustal evolution of SW Gondwana. In this study, a progression from immature, moderately altered rocks in the Cango Caves Group (Upper Neoproterozoic) to mature, strongly altered rocks in the Lower Palaeozoic Kansa Group and overlying formations is observed. Thus, rapid sedimentation of the former is anticipated, while the subsequent formations developed at a passive/rifted margin culminating in the laterally extensive deposition of the Peninsula Formation. Ongoing extensional movement is evident due to chronologically deeper-water facies and the progressive influence of a less fractionated component in the Cango Caves Group, particularly in the Huis Rivier Formation. The association of these rocks with an active margin is not certain since index trace element concentrations are too high for typical arc terranes. Thus, the mixing of a younger (570-600 Ma) magmatic source (close to an active margin) with mafic and felsic rocks of the older Mesoproterozoic Natal- Namaqua Mobile Belt (NMB) is the most likely possibility. A maximum, pre-Cape Granite age of 571 Ma can be assigned to the Huis Rivier Formation (Cango Caves Group) by detrital zircon dating, and thus correlation with the Malmesbury Group can be made. Ediacaran age zircons might be related to the active continental margin (Trans Antarctic Orogen) surrounding southern Gondwana, but this is still hypothetical. The post-Cape Granite Kansa Group and overlying Schoemanspoort Formation were most likely deposited as basin infill subsequent to folding and transtensional tectonics affecting the underlying Cango Caves Group. The Kansa Group may be comparable with the Klipheuwel Formation (southwest South Africa) in terms of its stratigraphic position beneath the Table Mountain Group. Deposition of the Table Mountain Group is much younger than previously believed in light of Ordovician zircon ages (471, 485, 499 Ma) obtained from the underlying Kansa Group. However, the provenance of these thus far unheard of ages for magmatic events in South Africa is a matter of contention. The proximal Ordovician Ross-Delamerian Orogenic event in Antarctica is the most likely source. Peninsula Formation deposition represents a cover sequence i.e. the culmination of small isolated basins (e.g. the Kansa Group and lower Table Mountain Group) into a larger, laterally extensive basin where reworking played a dominant role. This basin is likely to be a rift-related. However, it is not clear which crustal entity rifted away from vi South Africa and if, during the Ordovician an, active continental margin further to the south - bridging the South American Famatina Orogen with the Ross-Delamerian arc in Antarctica - existed. The Natal-Namaqua Mobile Belt appears to be the predominant source throughout the succession as indicated by Nd-isotope data and zircon populations. This implies that simple crustal recycling of Natal-Namaqua basement (or rocks with similar Nd-isotope characteristics) led to the genesis of the magmatic material younger than 1 Ga, observed in this study.

A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg, 2015.The Palaeoproterozoic Baoulé-Mossi domain of the West African Craton in northeastern Burkina Faso hosts numerous gold deposits such as Essakane and Tarpako. Integrated strato-tectonic, geophysical, geochemical, geochronological, regional stratigraphic framework and metallogenic studies of the Oudalan-Gorouol volcano-sedimentary Belt and the Gorom-Gorom Granitoid Terrane have provided new insight into the geotectonic evolution of the northeastern part of Burkina Faso. This work outlines the structural context and architecture necessary for forming these deposits. In this work, a new strato-tectonic model is proposed for the area by integrating field data and geophysical, geochemical, and geochronological data. The integrated data highlights and characterizes the setting of the Essakane gold mine and gold camp relative to the location of other regional gold deposits, metamorphosed Birimian Supergroup, intrusive rocks and shear zones. Structural, geochemical and geochronological analyses have helped to clarify the geological evolution of the Oudalan-Gorouol volcano-sedimentary Belt and the Gorom-Gorom Granitoid Terrane during the Tangaean (D1) and Eburnean (D2) orogenies through to the Wabo Tampelse Event (D3). Further to these, zircon U-Pb geochronology data have demonstrated that the Oudalan-Gorouol volcano-sedimentary Belt and the Gorom-Gorom Granitoid Terrane represent some of the oldest outcropping geology in the Palaeoproterozoic Baoulé-Mossi domain recognised to date. The geochronology and geology suggest that the basement or a pre- Birimian crust to the Birimian Supergroup may be found in the northeast of Burkina Faso. The Eburnean Orogeny in northeastern Burkina Faso is preceded by two phases of deformation (D1-x and D1), and two phases of magmatism. The first, D1-x, is associated with the emplacement of the Dori Batholith at the onset of D1 (2164 – 2141 Ma). D1 ductile-brittle deformation formed F1 folds and discrete high-strain mylonite zones that deformed the Oudalan- Gorouol volcano-sedimentary Belt and the Gorom-Gorom Granitoid Terrane during a southwestdirected palaeo-principal compressive stress. The pre-Birimian to Birimian supracrustal rocks and intrusions were regionally metamorphosed during D1 to greenschist to amphibolite facies with development of mineral assemblage of quartz-chlorite-muscovite ± chloritoid to biotite-potash feldspar ± hornblende. D1 is also associated with volcanic arc type calc-alkaline magmatism, producing TTGs enriched in heavy rare earth elements. The Eburnean Orogeny (2130 – 1980 Ma) is characterised by northwest-southeast shortening; it was followed by north-northwest - south-southeast shortening with development of northeast trending sinistral strike-slip faults and shears. D2 brittle-(ductile) deformation is manifested by refolding of F1 by northeast-trending F2, and development of a pervasive northeast-trending S2 to S2-C foliation. Metamorphic grade attained greenschist facies during D2, with development of mineral assemblage of quartz-chlorite-muscovite ± actinolite. The Wabo Tampelse (D3) deformation event is brittle in character and does not significantly affect the regional geological architecture in the study area.

AbstractThe availability of clean planting materials and functional seed regulatory systems is indispensable for fostering a sustainable seed yam system. The Yam Improvement for Income and Food Security in West Africa (YIIFSWA) project of the International Institute of Tropical Agriculture (IITA) developed the capacity of National Agricultural Research Institutes (NARIs) in their use of standardized Temporary Immersion Bioreactor (TIB) and Vivipak (VP) systems for high-ratio propagation and post-flask handling of yam breeder seed plantlets. Foundation seed was enhanced by supporting five private seed companies in Nigeria and three in Ghana. They were equipped with aeroponic and hydroponic technologies for foundation seed tuber production using single-node vine seedlings. For certified seed, seed yam out-growers were trained in good agronomic practices and entrepreneurship for certified seed tuber production using the adaptive yam minisett technique (AYMT). New certification standards were established for various classes of seed produced using different propagation methods and quality assurance procedures in Ghana and Nigeria. The capacity of the national regulatory organizations in both countries was enhanced to implement seed quality control and certification. Increased public sensitization and advocacy were done to raise awareness among relevant stakeholders to enhance the uptake of the seed propagation technologies and ensure a smooth interaction between the public and private sectors. This chapter summarizes the accomplishments of YIIFSWA in Ghana and Nigeria and the spillover impact on the yam belt of West Africa and beyond. The key lessons could inform the design and implementation of more effective seed projects, especially for vegetatively propagated crops.

AbstractThe Organization for Security and Co-operation in Europe (OSCE), while primarily a security organisation, has always included economic and human baskets or dimensions. Currently, the Office of the Co-ordinator of OSCE Economic and Environmental Activities operates in four main areas: (1) good governance and anti-corruption, (2) money laundering and financing of terrorism, (3) transport, trade and border-crossing facilitation, and (4) labour migration. This chapter addresses developments in Central Asia since the dissolution of the Soviet Union that are relevant to the third area of OSCE operations. The chapter’s focus is on the potential for the landlocked Central Asian countries to become land-linked, using improved transport connections between East Asia and Europe to promote economic development through export diversification and growth. Rail services across Central Asia improved considerably during the 2010s. They have been resilient, despite strained political relations between Russia and the EU since 2014, and rail traffic between Europe and China continued to increase in 2020 despite the shock of COVID-19. Further infrastructure improvements are promised under China’s Belt and Road Initiative. However, the expanded network has been little used by Central Asian producers to create new international trade, and the improved infrastructure represents a potential opportunity rather than a past benefit. If the Central Asian economies are successful in taking advantage of the opportunity, it will stimulate their trade across the Eurasian region and help economic diversification. The main determinant of success will be national policies and national economic development. The chapter concludes with a discussion of the role of multilateral institutions and, in particular, the prospects for OSCE collaboration with existing fora to promote cooperation and economic development in Central Asia.

Full textAbstract:
Abstract A model and criterium for the jumping limit torque of timing belt drives are presented. The following parameters are considered: pulley geometry, belt geometry, belt strain stiffness, belt tooth stiffness, belt flexural rigidity, shaft stiffness and initial tension. Friction is important in separating jumping on driver and driven pulleys since the jumping behaviour is different at the two sides. Other parameters might influence the jumping limit torque as well. Moreover, great care must be taken to get good parameter data from the test setup. The present analysis is restricted to driven pulleys. Calculated results of jumping limit torque and shaft load are presented for an XL-belt drive. The results exhibit the same behaviour as test results presented in the literature.

Synchronous belt drives are widely employed to transmit rotation accurately. The belt spans between the driving and driven pulleys generate resonance when the transverse natural frequency of the belt, as in string vibration, matches the meshing frequency of the belt tooth and the pulley tooth. The resonance of the belt spans affects the behavior of the transmission error. In the present study, the mechanisms generating the transmission error in synchronous belt drives under installation tension and a pulley speed ratio of 1:1 are investigated theoretically and experimentally for the case in which the belt spans generate first mode vibration due to resonance. The calculated and experimental transmission errors show good agreement, and so the validity of our analysis is confirmed. The transmission error has a period of 1/2 of one pitch of the pulley, and is generated by the difference in displacement between the upper and lower belt spans, the difference in the amount of belt climbing at the beginning and end of meshing, and the generation of torque due to the moment of inertia on the driven side.

Abstract A nonlinear model is developed which describes the rotational response of automotive serpentine belt drive systems. Serpentine drives utilize a single (long) belt to drive all engine accessories from the crankshaft. An equilibrium analysis leads to a closed-form procedure for determining steady-state tensions in each, belt span. The equations of motion are linearized about the equilibrium state and rotational mode vibration characteristics are determined from the eigenvalue problem governing free response. Numerical solutions of the nonlinear equations of motion indicate that, under certain engine operating conditions, the dynamic tension fluctuations may be sufficient to cause the belt to slip on particular accessory pulleys. Experimental measurements of dynamic response are in good agreement with theoretical results and confirm theoretical predictions of system vibration, tension fluctuations, and slip.

In this investigation, a modeling procedure for a tire with flexible belt is developed. The elastic deformation of the belt is modeled using the finite element absolute nodal coordinate formulation which allows for describing large rotational motion and the nonlinear inertia effects; the curved structure of the flexible belt; and moving boundary resulting from tread/road interaction. Using a concept of elastic ring tire models, the sidewall flexibility of tires is modeled using circumferential/radial springs and dampers between the belt and rim, while the tangential tread/road contact force is modeled using friction elements defined at contact nodes within the curved belt elements. Numerical examples are presented in order to demonstrate the use of the flexible tire model developed in this investigation. Good agreements in the tire vibration characteristics obtained using the experiments and the proposed model are demonstrated. It is also shown that the proposed tire model can be used for assessing dynamic characteristics of tires in high frequency ranges resulting from the interaction to uneven roads.

Abstract The dissipative rolling friction moment in a simple belt-drive system is estimated both experimentally and computationally while taking into account the detachment events at the belt-pulley interface. Shear traction is estimated based on measurements of the shear strain along the contact arc. It is shown that the dissipative moment can be approximated by taking the difference between the shear traction and the load carried by the belt. A model is developed for analyzing the contributions of different components to this dissipative moment by considering both the volumetric and surface hysteresis losses. The computed rolling friction moment is found to be in good agreement with that estimated based on the experiments. It is also found that while the shear- and stretching-induced energy losses contribute the most to the dissipation in the belt drive system, the losses associated with the Schallamach waves of detachment make up a considerable portion of the dissipation in the driver case.

Full textAbstract:
In synchronous belt drives, transmission error is generated due to resonance of the belt spanning the driving and driven pulleys when the transverse natural frequency of the belt approaches the meshing frequency of the belt and the pulley teeth. The behavior of the transmission error caused by resonance has been assumed to be dependent on the installation tension. In the present study, the influence of installation tension on the transmission error in a synchronous belt drive was experimentally investigated for a case in which first mode vibration due to resonance was induced in both the upper and lower spans. In addition, an analysis of the transmission error based on the experimental results was carried out. A transmission error contains two components: one with a period equal to the pitch of the pulley, and the other with a period of half the pulley pitch. Good agreement was found between the calculation and experimental results, thus confirming the validity of the analysis method. For a fixed pulley speed, the transmission error was largest when the installation tension was applied at a position where the displacement of the upper span was equal to that of the lower span. When the installation tension was varied and the pulley speed was adjusted so that the belt experienced resonance, the transmission error decreased with an increase in installation tension.

Abstract The transmission error characteristics of a stepping motor drive timing belt system are investigated theoretically and experimentally for the fixed and the automatic tensioner. It is found that the amplitude of the transmission error θe due to the pulley eccentricity and θm due to the stepping motor torque variation decrease as the belt tension increases and the applied torque load increases. Also, θe can be reduced by using the automatic tensioner, while θm shows almost same magnitude for both tensioners. The theoretical results based on the bondgraph model are in good accordance with the experimental results.
