The corrosion products that formed on the surface of copper and carbon steel, having a bulb-shaped morphology characteristic of the addition of soluble salts, particularly sulphates and chlorides, were identified in the two stations.

Prevalence of gastrointestinal parasites in domestic dogs in Tabasco , southeastern Mexico. Full Text Available Abstract The overall goal of this study was to estimate the prevalence of gastrointestinal GI parasites in dogs in the city of Villahermosa in Tabasco , Mexico. The study population consisted of owned dogs that had limited access to public areas. A fecal sample was collected from each animal and examined for GI parasites by conventional macroscopic analysis and centrifugal flotation. Fecal samples from 80 Of these, 58 At least seven parasitic species were identified. The most common parasite was Ancylostoma caninum which was detected in 48 Other parasites detected on multiple occasions were Cystoisospora spp.

Three additional parasites, Dipylidium caninum, Trichuris vulpis and Uncinaria spp. No mixed parasitic infections were identified. In summary, we report a moderately high prevalence of GI parasites in owned dogs in Villahermosa, Tabasco. Several parasitic species identified in this study are recognized zoonotic pathogens which illustrates the important need to routinely monitor and treat dogs that live in close proximity to humans for parasitic infections.

Tabasco is the Mexican state that reported the highest number One of the characteristics of this region is that houses are located within cacao plantations. During the period , cases of leishmaniasis were reported in 77 We found that cocoa crops are a risk factor for the transmission of leishmaniasis OR: 3. The probability of transmission of leishmaniasis in areas with cocoa crops is greater than in communities without this crop. Levels of organochlorine pesticides residues in human adipose tissue, data from Tabasco , Mexico.

The pooled sample was divided according to sex of donors 75 female and 75 male. Significantly higher levels of all organochlorine pesticides in females were found. The sample was divided into three age's ranges , and years.

Los manuales de quimica en Espana : Protagonistas, terminologia, clasificaciones y orden pedagogico. La presente tesis doctoral es una investigacion sobre los manuales de quimica utilizados en Espana de a Este trabajo proporciona una perspectiva general de un tema relevante en las ultimas decadas en Historia de la Ciencia, el estudio de los libros de texto. De acuerdo con las ultimas investigaciones realizadas en este terreno, el acto pedagogico es considerado como un proceso creativo, como espacio de encuentro de actores e intereses muy diversos, matizando las ideas defendidas por Thomas S.

Recordemos que segun Kuhn, los libros de texto ofrecen una vision consensuada y normalizada del estado de la ciencia de su epoca, por lo que sus autores eliminan deliberadamente toda controversia y presentan asi una imagen distorsionada de la actividad cientifica. En cambio, se ha mostrado, por ejemplo, que en la ensenanza participan no solamente profesores y alumnos sino tambien otros muchos actores y todos ellos no unicamente con intereses puramente pedagogicos sino tambien con diversos intereses politicos y economicos que pueden conocerse a traves del estudio de los manuales.

En esta tesis se pretende analizar los manuales de quimica en Espana desde hasta Para poder llevar a cabo la investigacion ha sido necesario precisar el objeto de estudio libro de texto de quimica durante el periodo estudiado ya que no es adecuado adoptar la imagen actual de una disciplina que sufrio sustanciales cambios durante la epoca estudiada.

Esta investigacion se centra en un momento especialmente importante para la quimica y que algunos historiadores han llegado a considerar "revolucionario". Durante estos anos se produjo un cambio importante en las teorias quimicas sobre la combustion y el concepto de elemento, asi como una reforma terminologica que originaron la aparicion de importantes controversias.

Ademas, debido a la relacion de la quimica con otras disciplinas como la historia natural o la fisica ha sido necesario restringir el objeto de estudio.

In recent years, one of the most disconcerting issues in bioethics, a field closely related to legal disciplines, is surrogate gestation or surrogacy. Very little is known about the medical nature of these novel therapeutic processes in legal study. Different dilemmas emerge in the fields of ethics, medicine and law.

This paper analyses the normative content of the Tabasco civil regime with respect to the concepts, types and effects of surrogacy. It emphasizes the primacy of protecting the physical and emotional integrity of pregnant women and the legal protection of the nasciturus. In addition, this paper shows the exceptional nature of this prerogative for infertile people who cannot get pregnant through any other medical means, by posing surrogacy's ultima ratio regum characteristics.

Pollution by petroleum hydrocarbons in sediments from continental shelf of Tabasco State, Mexico. The Wider Caribbean is potentially one of the largest oil producing areas in the world. About 5 million of barrels are transported every day in the Caribbean, thus generating an intense tanker traffic. For all those reasons petroleum pollution is considered as the major environmental problem in the Wider Caribbean area and increasing day to day due to the use of petroleum as the main energy source. On the other hand, the continental shelf of Tabasco state actually represents one of the most productive areas for crude oil in the Gulf of Mexico.

It is not with death, however, but life, we have to do. Yet they were no more cruel than other nations of their day, and no more cruel relatively, according to the progress of humanity, than are we to-day. For example, the General Law on Linguistic Rights of Indigenous People guarantees the right to a trial in the language of indigenous peoples with someone who understands their culture. The results were compared with studies into their mineralogical characterization, a quantitative chemical analysis and a determination of potential acidity and potential neutralization by the ABA acid-base accounting method applied to samples of tailings.

Some analytical models are presented and discussed in great detail. The purpose of this is to contribute, in particular, to the following aspects: First, it attempts to be a reference work for the geotechnical engineers facing problems related to the seismic wave propagation phenomenon in buried structures, since within the consulted literature there are many of the principles presented in here, that are related with the seismic engineering, the reaction module, as well as expressions or investigations performed in piles.

Second, a cuasi-static numerical model is presented that analyzes the continuous piping through a stress vector of sinusoidal type. The analysis of the stresses and deformations that the ground transmits to the pipe is made using a ground-to-pipe interaction model.

For a low level of deformations an elastic behavior of transference in the interface is considered in the inter-phase ground-piping. In the case of greater deformations it is assumed that sliding is presented because the surrounding ground presents fault by shearing stress in the surrounding ground. The analysis covers solely the case with axial deformations in straight sections. Finally, it intends to give a series of recommendations for future research works on the modeling of buried pipelines. In this work, the influence of several aspects on the response of the pipelines to the propagation of seismic waves is analyzed and discussed; such as the conditions of topography, geology, ground stratigraphy and the rigidity changes in the surrounding ground of the pipe.

Full Text Available During the second half of the sixteenth century, the post of public defender of Indians spread throughout Spanish America, and its missions became more precisely defined, contributing to this effect both the way in which these officers executed their tasks and the publication of legal texts on the matter, conceived by local or metropolitan authorities.

By , the protector and defender of Indians or naturales became the essential piece of the recently-created Juzgado General de Indios, an authentic Indian institution that would last until the late colonial period. Besides revealing the public defenders' identities, status, and wages, the author analyzes their dealings with colonial authorities —the governors of Yucatan, the Royal Audiencias, and the Consejo de Indias—, as well as the Tabaso Indians. All this allows us to understand the central importance this post acquired, not only in the colonial judicial system, but also in the Spanish American government.

Full Text Available Cuniculus paca is widely distributed throughout the Neotropics. Known as the paca, it is the largest rodent in the Mexican tropical forests, and one of the most used as a subsistence species for its meat. Since colonial times, this species has been subject of an unreported hunting pressure. For this reason, the aim of this work was to describe the use of the paca by the inhabitants of the Sierra de Tabasco State Park STSP using sampling areas in a matrix of vegetation with different degrees of disturbance, and different types of land use.

We included both preserved areas: owing to the presence of large continuous areas of fragmented rainforest and areas that are not preserved, with smaller rainforest fragments and more isolated. All those interviewed had eaten paca meat, and indicated that this species is most frequently observed in the rainforest during the dry season.
