Studies on Ilmenite of Chavara and Manavalakurichi Deposites, Southwest Coast of India

The present work attempts to trace the variation in the physical and chemical behavior of ilmenite, since its release from country rocks and subsequent transportation to the coast through the progressive weathering environments of laterite, sedimentary rocks, rivers and estuarine systems. Since the hinterland of the study area consists of crystalline and sedimentary rocks and their weathered forms (laterites), the contribution of each lithological system to the beach placer is attempted. The results of the study show that the most magnetic fraction contains more content of altered phases than the relatively unweathered fractions. The fractions separated above 0.35A define a high grade of ilmenite ore enriched in Ti content. The lattice volume generally decreases with alteration. The magnetic studies revels that the Chavara ilmenite are found to be made up to low magnetic crops with about 46% of the bulk ilmenite constituted by fractions separated at above 0.35A. In the Manavalakurichi ilmenite on the other hand, around 91% of the beach ilmenite is made of fractions separated at or below 0.3A

Texture, composition and provinance of innershelf sediments between Narakkal and Purakkad, Kerala with special reference to the formation of Mud Banks

The continental shelf of southwest coast of India (Kerala) is broader and . flatter compared to that of the east coast. The unique characteristic feature of the study area (innershelf between Narakkal and Purakkad) is the intermittent appearance of 'mud banks' at certain locations during southwest monsoon. The strong seasonality manifests significant changes in the wind, waves, currents, rainfall, drainage etc., along this area. Peculiar geomorphological variation with high, mid and lowlands in the narrow strip of the hinterland, the geological formations mainly consisting of rocks of metamorphic origin and the humid tropical weathering conditions play significant role in regulating the shelf sedimentation. A complementary pattern of distri bution is observed for clay that shows an abundance in the nearshore. Silt, to a major extent, depicts semblance with clay distribution . Summation of the total asymmetry of grain size distribution are inferred from the variation of skewness and kurtosis.Factor I implies a low energy regime where the transportation and deposition phases are controlled mostly by pelagic suspension process as the factor loadings are dominant on finer phi sizes. The second Factor is inferred to be the result of a high energy regime which gives higher loadings on coarser size fractions. The third Factor which might be a transition phase (medium energy regime) representing the resultant flux of coastal circulation of the re-suspension/deposition and an onshoreoffshore advection by reworking and co-deposition of relict and modern sediments. The spatial variations of the energy regime based on the three end-member factor model exhibits high energy zone in the seaward portion transcending to a low energy one towards the coast.From the combined analysis of granulometry and SEM studies, it is concluded that the sandy patches beyond 20 m depth are of relict nature. They are the resultant responses of beach activity during the lower stand of sea level in the Holocene. Re-crystallisation features on the quartz grains indicate that they were exposed to subaerial weathering process subsequent to thei r deposition

Mineralogical And Sedimentological Studies Of Innershelf And Beach Sediments Along The Coast Between Paravur And Kovalam, South Kerala, India

Continental shelf is of particular significance in marine geology , because it links the two basically different structural zones in the earth's crust; the continents and ocean basins. The shelf area has much wider importance in many fields of activity such as scientific, economic, social, political and strategic. The pace of development has ultimately put pressure on mankind to look for exploitable resources and accessibility to the continental shelf area and beyond. Added to the above, the developmental activities in the coastal area would readily and directly influence the innershelf sediments. This situation demands a thorough geological knowledge of the continental shelf area. Moreover, a successful management of the continental shelf zone requires an optimum data base on the physico-chemical nature of the shelf sediments. Although sedimentological studies were carried out along the western continental shelf of India, a well documented systematic study of the inner shelf off Trivandrum coast is still found to be lacking. Considering the physiographic settings and the vicinity of two renowned placer deposits at Chavara and Manavalakurichi, such a sedimetological inventory has become all the more vital. In view of the above, a research programme has been drawn up to account the salient sedimentological and mineralogical aspects of the innershelf and beach sediments between Paravur and Kovalam, Trivandrum district, Kerala (latitudes 8° 7'00" to 8° 47'45" and longitudes 76°43'00" to 77° 40'45"). The findings are presented in six chapters formatted to address the aim of this research.

Análisis comparativo de la situación actual de los puertos secos en tres contextos diferentes: Colombia, México, España

El presente trabajo tiene como finalidad analizar y comparar Puertos Secos en tres países diferentes: Colombia, México y España; y con ello determinar las claves o herramientas para el éxito de estos. Para esto, la investigación se llevó a cabo a nivel documental y teórico, abarcando desde documentos de investigación académicos y de entidades supranacionales, hasta documentos de carácter legislativo de diferente orden, para los tres países de estudio, incluyendo estudios privados y herramientas estadísticas propias de los Puertos Secos o sus empresas concesionarias. Gracias a todo esto, se pudo desarrollar el documento con la siguiente estructura: Historia, Referencias, Legislación y Descripción. En la primera etapa, resalta el enfoque de desarrollo portuario y de promoción del tren como medio de transporte y herramienta comercial; en la segunda etapa, se corrobora la dificultad que estos proyectos enfrentan en Colombia por parte del sector público centralista y carente de visión y una precaria participación del sector privado; en la tercera etapa se ratifica esto al ser la principal diferencia el enfoque logístico en la legislación, partiendo de la constitución misma, y su presencia o ausencia en los marcos legales de cada país; y se termina con el resultado de estos elementos previos condensado en elementos tangibles en México y España, y tan solo ilusiones y fracasos para Colombia. Por todo lo anterior, se llega a la conclusión que un Marco Jurídico bien estructurado, una fuerte Inversión del Sector Público y Privado, y una Voluntad Política de largo impulso son las claves para el éxito de estos proyectos, y todo lo que viene ligado a ellos.

Tentativas del “enemigo malo” Relaciones ilícitas e infanticidios en la Provincia de Antioquia (Nueva Granada) 1765-1803

El texto constituye un ejercicio de microhistoria y Antropología histórica que busca aportar a la historiografía colombiana información sobre las formas de comprender el crimen (el infanticidio y los comportamientos escandalosos como el adulterio, el concubinato y el incesto), el problema del honor durante finales del siglo XVIII –pues la mayoría de estudios han versado sobre el siglo XIX- y las configuraciones familiares (particularmente las actitudes maternales y paternales) al interior de la provincia de Antioquia. Usualmente estos temas se han tratado por separado y con diversas fuentes, pero este texto busca una visión general a partir de la participación de las personas en calidad de implicados, testigos y funcionarios en los juicios criminales.

Os missionários da Educação e o Instituto Ponte Nova da Bahia

Durante cem anos – 1871 a 1971 – os missionários da Missão Central do Brasil, vinculados à Igreja Presbiteriana do Norte dos Estados Unidos (PCUSA), partindo da Bahia, organizaram igrejas, escolas e hospitais em sua área de jurisdição – Sergipe, Mato Grosso, Goiás e norte de Minas Gerais. Verifi cando a realidade do hinterland brasileiro, William Alfred Waddell propôs um novo tipo de instituição educacional, distinta do modelo do Mackenzie College, de São Paulo: uma escola secundária rural, que ofereceria os cursos normal, preparatório de pastores, auxiliar de enfermagem e técnico agrícola. O IPN, como fi cou conhecido o Instituto Ponte Nova, foi fundado pela Missão em 1906, a qual organizou e subsidiou até 1971, além da escola, uma igreja e uma escola de auxiliar de enfermagem, a primeira escola do gênero na Bahia, ao lado do Grace Memorial Hospital. O sucesso daquele complexo institucional, integrando religião, educação e saúde, levou a Missão a organizar um projeto denominado “Escolas Ponte Nova”. Em 1926, a Missão já tinha aberto no território de sua jurisdição, sete escolas naquele modelo proposto e quatro hospitais.

Mirada de viajeros e historiografía: la campaña de Buenos Aires al concluir el s. XVIII (Estudios)

El artículo revisa los relatos de Francisco de Amigorena y de Alexander Gillespie, un funcionario y un militar, escritos a fines del siglo XVIII e inicios del XIX, que han sido la base de la historiografía tradicional argentina sobre el mundo rural de Buenos Aires. Desde la perspectiva de la nueva historiografía económica argentina y de la historia del paisaje, replantea la imagen de la conformación de las clases dominantes rurales de la época y el papel económico del interior de la pampa de la provincia de Buenos Aires. Específicamente, el artículo cuestiona la idea de un espacio desierto, tal como la pintó la historiografía romántica, y propone el perfil de un hinterland heterogéneo, dedicado a distintas actividades.

Guayaquil: un puerto colonial en los mares del sur, siglo XVIII (Estudios)

Este artículo analiza el emplazamiento urbano, las dinámicas económicas y las relaciones sociales que caracterizaron a Guayaquil durante el XVIII. El desarrollo económico y productivo que experimentó la ciudad-puerto se debió a su feraz entorno natural y a las posibilidades de comunicación que brindó el sistema fluvial del Guayas. Se analizan las particularidades de su estructura social, las relaciones entre la élite y los sectores subalternos, la estructura político-administrativa del Cabildo y la influencia que este centro urbano ejerció sobre los pueblos y partidos ubicados en su hinterland.

Small towns as 'sub-poles' in English rural development: Investigating rural-urban linkages using sub-regional social accounting matrices

This paper uses spatial economic data from four small English towns to measure the strength of economic integration between town and hinterland and to estimate the magnitude of town-hinterland spill-over effects. Following estimation of local integration indicators and inter-locale flows, sub-regional social accounting matrices (SAMs) are developed to estimate the strength of local employment and output multipliers for various economic sectors. The potential value of a town as a 'sub-pole' in local economic development is shown to be dependent on structural differences in the local economy, such as the particular mix of firms within towns. Although the multipliers are generally small, indicating a low level of local linkages, some sectors, particularly financial services and banking, show consistently higher multipliers for both output and employment.

City futures: exploring urban retrofit and sustainable transitions

Cities are responsible for up to 70% of global carbon emissions and 75% of global energy consumption. By 2050 it is estimated that 70% of the world's population will live in cities. The critical challenge for contemporary urbanism, therefore, is to understand how to develop the knowledge, capacity and capability for public agencies, the private sector and multiple users in city-regions (i.e. the city and its wider hinterland) to re-engineer systemically their built environment and urban infrastructure in response to climate change and resource constraints. To inform transitions to urban sustainability, key stakeholders' perceptions were sought though a participatory backcasting and scenario foresight process in order to illuminate challenging but realistic socio-technical scenarios for the systemic retrofit of core UK city-regions. The challenge of conceptualizing complex urban transitions is explored across multiple socio-technical ‘regimes’ (housing, non-domestic buildings, urban infrastructure), scales (building, neighbourhood, city-region), and domains (energy, water, use of resources) within a participatory process. The development of three archetypal ‘guiding visions’ of retrofit city-regional futures developed through this process are discussed, along with the contribution that such foresight processes might play in ‘opening up’ the governance and strategic navigation of urban sustainability.
