Urban Sprawl Pattern Analysis Using GIS

Urbanisation has evinced interest from a wide section of the society including experts, amateurs, and novices. The multidisciplinary scope of the subject invokes the interest from ecologists, to urban planners and civil engineers, to sociologists, to administrators and policy makers, students and finally the common man. With the development and infrastructure initiatives mostly around the urban centres, the impacts of urbanisation and sprawl would be on the environment and the natural resources. The wisdom lies in how effectively we plan the urban growth without - hampering the environment, excessively harnessing the natural resources and eventually disturbing the natural set-up. The research on these help urban residents and policymakers make informed decisions and take action to restore these resources before they are lost. Ultimately the power to balance the urban ecosystems rests with regional awareness, policies, administration practices, management issues and operational problems. This publication on urban systems is aimed at helping scientists, policy makers, engineers, urban planners and ultimately the common man to visualise how towns and cities grow over a period of time based on investigations in the regions around the highway and cities. Two important highways in Karnataka, South India, viz., Bangalore - Mysore highway and the Mangalore - Udupi highway, in Karnataka and the Tiruchirapalli - Tanjavore - Kumbakonam triangular road network in Tamil Nadu, South India, were considered in this investigation. Geographic Information System and Remote Sensing data were used to analyse the pattern of urbanisation. This was coupled with the spatial and temporal data from the Survey of India toposheets (for 1972), satellite imageries procured from National Remote Sensing Agency (NRSA) (LANDSAT TM for 1987 and IRS LISS III for 1999), demographic details from the Census of India (1971, 1981, 1991 and 2001) and the village maps from the Directorate of Survey Settlements and Land Records, Government of Karnataka. All this enabled in quantifying the increase in the built-up area for nearly three decades. With intent of identifying the potential sprawl zones, this could be modelled and projected for the future decades. Apart from these the study could quantify some of the metrics that could be used in the study of urban sprawl.

Familial Diarrhea Syndrome Caused by an Activating GUCY2C Mutation

BACKGROUND Familial diarrhea disorders are, in most cases, severe and caused by recessive mutations. We describe the cause of a novel dominant disease in 32 members of a Norwegian family. The affected members have chronic diarrhea that is of early onset, is relatively mild, and is associated with increased susceptibility to inflammatory bowel disease, small-bowel obstruction, and esophagitis. METHODS We used linkage analysis, based on arrays with single-nucleotide polymorphisms, to identify a candidate region on chromosome 12 and then sequenced GUCY2C, encoding guanylate cyclase C (GC-C), an intestinal receptor for bacterial heat-stable enterotoxins. We performed exome sequencing of the entire candidate region from three affected family members, to exclude the possibility that mutations in genes other than GUCY2C could cause or contribute to susceptibility to the disease. We carried out functional studies of mutant GC-C using HEK293T cells. RESULTS We identified a heterozygous missense mutation (c.2519G -> T) in GUCY2C in all affected family members and observed no other rare variants in the exons of genes in the candidate region. Exposure of the mutant receptor to its ligands resulted in markedly increased production of cyclic guanosine monophosphate (cGMP). This may cause hyperactivation of the cystic fibrosis transmembrane regulator (CFTR), leading to increased chloride and water secretion from the enterocytes, and may thus explain the chronic diarrhea in the affected family members. CONCLUSIONS Increased GC-C signaling disturbs normal bowel function and appears to have a proinflammatory effect, either through increased chloride secretion or additional effects of elevated cellular cGMP. Further investigation of the relevance of genetic variants affecting the GC-C-CFTR pathway to conditions such as Crohn's disease is warranted.

Seismic site classification and correlation between standard penetration test N value and shear wave velocity for Lucknow city in Indo-Gangetic basin

Subsurface lithology and seismic site classification of Lucknow urban center located in the central part of the Indo-Gangetic Basin (IGB) are presented based on detailed shallow subsurface investigations and borehole analysis. These are done by carrying out 47 seismic surface wave tests using multichannel analysis of surface waves (MASW) and 23 boreholes drilled up to 30 m with standard penetration test (SPT) N values. Subsurface lithology profiles drawn from the drilled boreholes show low- to medium-compressibility clay and silty to poorly graded sand available till depth of 30 m. In addition, deeper boreholes (depth >150 m) were collected from the Lucknow Jal Nigam (Water Corporation), Government of Uttar Pradesh to understand deeper subsoil stratification. Deeper boreholes in this paper refer to those with depth over 150 m. These reports show the presence of clay mix with sand and Kankar at some locations till a depth of 150 m, followed by layers of sand, clay, and Kankar up to 400 m. Based on the available details, shallow and deeper cross-sections through Lucknow are presented. Shear wave velocity (SWV) and N-SPT values were measured for the study area using MASW and SPT testing. Measured SWV and N-SPT values for the same locations were found to be comparable. These values were used to estimate 30 m average values of N-SPT (N-30) and SWV (V-s(30)) for seismic site classification of the study area as per the National Earthquake Hazards Reduction Program (NEHRP) soil classification system. Based on the NEHRP classification, the entire study area is classified into site class C and D based on V-s(30) and site class D and E based on N-30. The issue of larger amplification during future seismic events is highlighted for a major part of the study area which comes under site class D and E. Also, the mismatch of site classes based on N-30 and V-s(30) raises the question of the suitability of the NEHRP classification system for the study region. Further, 17 sets of SPT and SWV data are used to develop a correlation between N-SPT and SWV. This represents a first attempt of seismic site classification and correlation between N-SPT and SWV in the Indo-Gangetic Basin.

Propiedad privada, abasto y regulación del comercio y la circulación de mercancías en la campaña de Buenos Aires : desde fines de la colonia al gobierno de Martín Rodríguez

Resumen: El artículo indaga en la fiscalidad sobre el comercio interior de Buenos Aires y su relación con la consolidación de la propiedad privada en la campaña. A partir de un estudio de caso, se examinan las particularidades de las imposiciones fiscales sobre las actividades comerciales en el ámbito rural identificando cambios y continuidades en las formas de recaudación y gravamen. Este análisis se combina con el de los problemas que las prácticas ilegales vinculadas al abasto de ganado presentó tanto en su circulación en la campaña como en su introducción a los mercados citadinos. Ambas cuestiones son contrastadas con lo sucedido a partir de 1822, cuando durante el gobierno de Martín Rodríguez tanto el comercio como la circulación de ganado en el Hinterland intentarían ser regulados con mayor énfasis a fin de asegurar el respeto de la propiedad privada en el mundo rural.

O governo de Tibério e a difícil arte de suceder bons imperadores

Resumo: Neste artigo, propomo-nos a analisar o Governo do Imperador Romano Tibério, da forma como foi descrito por Dion Cássio Cocceiano na obra História Romana. Dion Cássio foi senador na passagem do II para o III século d.C. e sua narrativa nos chegou bastante fragmentada, reconstruída a partir dos excertos de Xifilino e Zonaras. A autoridade do Príncipe não era hereditária. Assim, tornavase necessário refazer os laços de patronato e amicitia no início de cada governo. E esta não era uma tarefa fácil, nem mesmo para Tibério que sucedeu o considerado bom Imperador Otávio Augusto.

Antonio Somellera : un testimonio de violencia política en tiempos de Rosas (1838-1840)

La obra publicada hacia fines del siglo XIX por el Comodoro Antonio Somellera (1812-1889) bajo el nombre Recuerdos de una víctima de la Mazorca, es un valiosísimo documento histórico para analizar los hechos e ideas que determinaron muchos de los aspectos de la vida política del momento al que se refiere, el gobierno de Juan Manuel de Rosas en Buenos Aires durante 1838-1840. Allí se expresa cabalmente uno de los elementos más controvertidos de la historia del país: la violencia política, tanto física como discursiva, a que estaban acostumbrados todos los hombres que dirigían, ya sea como gobierno o como oposición, los destinos de la Argentina. A través de un análisis contextualizado y profundo de estas Memorias, el presente trabajo buscará dilucidar algunos de los aspectos estructurales que caracterizaron la realidad política de esos años.

Gestión del riesgo operativo en las entidades de crédito: un camino sin retorno

[ES] Este trabajo presenta la problemática de la gestión del riesgo operativo en las entidades de crédito en el ámbito europeo. Aprobado el texto definitivo del denominado Comité de Supervisión Bancaria (Basilea II), con especial y novedosa regulación del riesgo operativo, amanece como inminente su integración e la regulación bancaria de la UE, y, por tanto, su pronta implantación y supervisión por las autoridades monetarias y financieras. Esta nueva normativa, de carácter flexible y profesional, introduce en el seno del gobierno corporativo de las entidades de crédito nuevos elementos que afectarán a su cultura interna (cultura de gestión de los riesgos), afectando a las decisiones estratégicas y a la organización de las entidades, incentivando a la mejora de la calidad de sus procesos, servicios y operaciones. Todo lo cual supone una acicate para perseguir la eficiencia continua a nivel individual y a nivel del sistema financiero, con visos de adquirir dimensión estratégica. De esta manera, se abre un espacio para la investigación y creatividad en la aplicación y desarrollo de los postulados científicos de la Economía de la Empresa, con posibilidades de incorporarlos a otros sectores empresariales de similar afectación por los riesgos operativos.

Information Access Survey: Vietnam

Vietnam has an estimated 300,000 ha of water bodies throughout the country, plus about 3,200 km of coastline. The Government of Vietnam promotes development of aquaculture as an important part of the fisheries sector. The Government of Vietnam has recently placed particular emphasis on the importance of effective aquatic resources management for poverty alleviation. A great number of national and international activities, projects and organizations currently operate within the aquatic resources management sector in Vietnam. In a country with limited resources, the importance of efficient and effective information exchange among stakeholders within the sector, and between the sector and aquatic resources users, is increasingly being recognized.

Two worlds across a highway

The Government of Pakistan and FAO have put into practice a participatory process that sought to involve as wide a range of stakeholders as possible, with two rounds of consultations ‘close’ to people in communities and in some cases, actually with poor people and women. This is the relation of one day of these consultations in a little Pakistani village called Chilya. (Pdf contains 5 pages).

Community Fisheries Development Office (CFDO) strategic plan, January 2004

In October 2000 the government of Cambodia announced a major change in fisheries management policy. The core elements of the new policy are the reduction of fishing lot concession areas by 56%, the broader participation of fishing communities in the management of fisheries and a focus on the efficient, sustainable and equitable use of the living aquatic resources. To facilitate the establishment and development of the Community Fisheries, support and monitor their activities, the Department of Fisheries was authorized1 to establish a Community Fisheries Development Office (CFDO).

Schadstoffüberwachung in Meeresfischen

For assessing the status of the marine environment of the North Sea and the Baltic Sea, international monitoring programmes are performed in the framework of the international conventions for the protection of the marine environment of the North Atlantic Ocean and the Baltic Sea. The German contribution to these programmes is covered by the national Joint Marine Monitoring Programme, which is carried out by several institutes of the coastal Federal States and the Federal Government of Germany. The Institute for Fishery Ecology of the Federal Fisheries Research Centre is responsible for the investigations of harmful substances in fish samples from the open sea areas. This article gives a short description of how this task is performed and, as an example, how concentrations of polychlorinated biphenyls and mercury in plaice from the German Bight have developed over a period of thirteen and eight years, respectively.
