El deseo de la mayoría de los empresarios es que su empresa tenga presencia en todas las partes del mundo que se pueda. Sin embargo, son pocos los que lo logran. Muchos menos los que son perdurables en el mercado internacional. Y todo esto ocurre en gran parte por el desconocimiento que tienen sobre ese entorno. Especialmente, el empresario o emprendedor colombiano, se caracteriza por no ir más allá de soñar con lograr posicionarse en el exterior, mas no trabajar para lograrlo. Este trabajo tiene como fin ayudar al empresario colombiano en ese objetivo. Pretende mostrar un contexto más profundo de, en este caso, el mercado de Estados Unidos (en los estados de Texas, South Carolina y Tennessee), para que las empresas tengan herramientas que faciliten su labor internacional. Todo esto, en el marco del Tratado de Libre Comercio entre Colombia y Estados Unidos, que entró en vigencia hace algunos años. La metodología usada para la realización de este documento, incluye una revisión bibliográfica que explica la importancia de la internacionalización empresarial; la consulta de bases de datos para elaborar un perfil exportador/importador a nivel país y a nivel estado; y la identificación de potencialidades y oportunidades que pueda tener el empresario colombiano en estos territorios específicos.

In this thesis, Ph.D candidate presents a compact sensor node (SN) designed for long-term and real-time acoustic emission (AE) monitoring of above ground storage tanks (ASTs). Each SN exploits up to three inexpensive low-frequency sensors based on piezoelectric diaphragms for effective leakage detection, and it is capable by means of built-in Digital Signal Processing functionalities to process the acquired time waveforms extracting the AE features usually required by testing protocols. Alternatively, capability to plug three high frequency AE sensors to a SN for corrosion simulated phenomena detection is envisaged and demonstrated. Another innovative aspect that the Ph.D candidate presents in this work is an alternative mathematical model of corrosion location on the bottom of the AST. This approach implies considering the three-dimensional localization model versus the two-dimensional commonly used according to the literature. This approach is aimed at significant optimization in the number of sensors in relation to the standard approach for solving localization problems as well as to allow filtering the false AE events related to the condensate droplets from AST ceiling. The technological implementation of this concept required the solution of a number of technical problems, such as the precise time of arrival (ToA) signal estimation, vertical localization of the AE source and multilaration solution that were discussed in detail in this work. To validate the developed prototype, several experimental campaigns were organized that included the simulation of target phenomena both in laboratory conditions and on a real water storage tank. The presented test results demonstrate the successful application of the developed AE system both for simulated leaks and for corrosion processes on the tank bottom. Mathematical and technological algorithms for localization and characterization of AE signals implemented during the development of the prototype are also confirmed by the test results.

The Iowa Department of Natural Resources (IDNR) asked the Iowa Department of Public Health (IDPH) Hazardous Waste Site Health Assessment Program to perform a health consultation for the Climbing Hill, Iowa, groundwater contamination site. IDNR wants to know if the site poses a public health hazard. The information in this health consultation was current at the time of writing. Data that emerges later could alter this document’s conclusions and recommendations. Climbing Hill is an unincorporated town in Woodbury County, Iowa, approximately 15 miles southeast of Sioux City. The town has approximately 120 residents. All of the residents and most businesses within the town use private wells to supply their drinking water. The local restaurant has an individual well that is classified as a public water supply system because it has the potential to serve more than 25 people in a day. Several wells in the town have become contaminated with gasoline and diesel fuel leaking from two underground storage tanks. All of the wells are roughly 75–80 feet deep (R. Cardinale, IDNR, Underground Storage Tank Section, personal communication, January 30, 2004).

After decades of polluting actions the environment manifests serious and global consequences. The contamination of soils and groundwater by organic compounds is a widespread problem mainly on account of contamination by leakage from underground storage tanks, which often results in the release of gasoline or other chemicals. The main problem about groundwater contamination is due to the toxicity of water-soluble components such as benzene, toluene and xylene (BTX). In the present work a study about classical and modern methods for remediation of BTX is reported.

Underground storage tanks (UST) are widely used in the Porto Velho area. A large number of these USTs are in bad condition due to corrosion processes causing groundwater contamination. A large number of these leaking underground fuel tanks (LUFT) are in urban areas but due to the lack of water quality monitoring, they are only detected when there is a high contamination level. This study identified petroleum hydrocarbons, derived from a LUFT, by a silica gel/petroleum ether partitioning gravimetric method and by gas chromatographic analysis of samples collected in wells dug in a gas station and in houses in the aforementioned neighborhood.

The contamination of underground waters is a subject of great importance, since a lot of people use this kind of source for public supply. This paperwork manages with how gas stations can contaminate these waters and what are some remediation techniques, used nowadays to solve this problem. The contamination caused by the gas stations can have its origin in the underground storage tanks when they suffer corrosion and show leaking problems. It’s a topic of great relevance, because the hydrocarbons derivated from petroleum present in the fuels can stay for a long time in the environment. Besides that, an analyses of the risk of contamination by gas stations in the city of Rio Claro was made based on three parameters: density of the gas stations, depth of the underground water and hydraulic conductivity. To achieve such goal, maps were elaborated considering those parameters individually and considering the three of them together. Analyzing those maps, it was concluded see that the spots that represent the biggest risks of contamination in Rio Claro are located southeast and center-west.

Leaking of hydrocarbon in fuel underground storage tanks constitute object of concern for urban environmental management, because therefore they provoke damages to the physical, biological and socioeconomic environment. Though laws that regulate this essential activity exist, aiming at to prevent contamination with hydrocarbon, we observe that this still happens. This fact evidences that the selection of places for installation of gas stations has not considered the characteristics of the natural environment, implying in more critical consequences associated to the leaking. The objective of this work is to elaborate a chart applied to the gas stations in Rio Claro/SP. The determination of the Index of Environmental Sensitivity for elaboration of such chart was carried through breaking the selection of factors of Environmental Sensitivity of physical, biological and socioeconomic environment. The balance of these factors was given by means of Ad hoc consultation. The crossing of the information was carried through using the method of overlapping of overlays. The result is a chart that shows us areas with classes of high, middle and low Environmental Sensitivity. One gives credit that this type of material can be used as criterion in the selection of adjusted areas for installations of new gas stations and management of the already installed gas stations. The diagnosis of the current situation of the gas stations in the area and recommendations had also been elaborated.

The primary purpose of this thesis was to design and create an Interactive Audit to conduct Environmental Site Assessments according to American Society of Testing Material's (ASTM) Phase I Standards at the Wagner Creek study area. ArcPad and ArcIMS are the major software that were used to create the model and ArcGIS Desktop was used for data analysis and to export shapefile symbology to ArcPad. Geographic Information Systems (GIS) is an effective tool to deploy these purposes. This technology was utilized to carry out data collection, data analysis and to display data interactively on the Internet. Electronic forms, customized for mobile devices were used to survey sites. This is an easy and fast way to collect and modify field data. New data such as land use, recognized environmental conditions, and underground storage tanks can be added into existing datasets. An updated map is then generated and uploaded to the Internet using ArcIMS technology. The field investigator has the option to generate and view the Inspection Form at the end of his survey on site, or print a hardcopy at base. The mobile device also automatically generates preliminary editable Executive Reports for any inspected site.
