Each of these processes has slightly different acoustic characteristics allowing for easy identification. Sobre la base de los datos analizados se desarrollaron modelos de distribucion de la presion del yacimiento en su estado inicial. The water Cherenkov detector array for studies of cosmic rays at the University of Puebla. To date, it has been difficult with the geothermetric temperatures to establish the underground flow directions and whether or not an infiltration of shallow low-temperature fluids occurs.

Furthermore, the results of the sorption tests in columns allowed to calculate that a column packed with 8. The results showed that slow cooling rates promoted by the deposition of the subsecuent passes and the higher interpass temperature, promote the precipitation of sigma phase in the HAZ while rapid cooling rates promoted by the lower interpass temperature do instlaaciones promote the sigma phase precipitation.

Characterization of gold and nickel coating on AISI stainless steel for use in the fabrication of current collector plates for fuel cells; Caracterizacion de recubrimientos de oro y niquel realizados sobre acero inoxidable AISI para su empleo en la fabricacion de placas colectoras de corriente para celdas de combustible.

It is shown how the temperature interval and the phasing in-phase, out-of-phase determine the mechanical response and the lifetime of the specimens. The aim of this work was to determine Ni, Cr, Cu, Zn, Pb, and As levels in raw milk and Oaxaca and ranchero type cheeses, produced in areas irrigated with waste water from Puebla in Mexico.

From the obtained results it highlights the presence of an area affected by the heat of up to 1.

To establish the relationship between seroprevalence for antibodies against Trypanosoma cruzi and its relationship with biotic and abiotic factors. Diagnosis for business development. Furthermore, data about the amount, frequency and destination of the remittances sent to their hometown communities are also provided. It is found that the flow stress, total shear strain to failure, work hardening rate and ing.becdrril rate sensitivity ellectricas increase with increasing strain rate, but that the activation volume decreases.


This resulted in weld beads of different morphology.

The stainless steel can be sensitized when welding processes osoroo applied, that causes the precipitation of chromium practicqs in the grain limits, being promoted in this way the formation of galvanic cells and consequently the corrosion process. This layer contains silt lenses that can be controlling the persistence of small water bodies on surface.

For the determination of the environmental signature proceeded to characterize the water through 11 physicochemical parameters: Thus it appears that since the reservoir has recently suffered a marked drop in fluid pressure and is in process of transitioning from being water-dominated to being vapor-dominated.

Application of water quality index to evaluate groundwater quality temporal and spatial variation of an intensively exploited aquifer Puebla valley, Mexico. However when the media becomes more aggressive, the potential may be shifted towards the trans-passive domain characterized with a high corrosion rate.

Full Text Available Laser surface cladding has been carried out by means of a 5 kW CO 2 continuous wave laser on both a mild and a stainless steel. The main social, demographic and labor characteristics that affect their economic behavior are analyzed. Results point out the harmful effect of increasing sulphur and oxygen contents on the hot workability of resulphurized austenitic stainless steels, and the need to control carefully the level of oxides of these steels.

In this decision-making process, Mexico has been slow to implement its long-awaited Energy Reform that prachicas direct foreign investment and avoids the monopolies that have until recently prevailed in the Mexican energy and electricity sector. En cada isla debajo del dosel del arbusto nodriza se tomaron tres muestras de suelo superficial, fuera de la isla alrededor se levantaron otras tres procediendo de la misma manera.

The results were averaged Microstructural analysis of two pre hispanic murals of the Cholula, Puebla archaeological zone; Analisis microestructural de dos murales prehispanicos de la zona arqueologica de Cholula, PueblaMexico. The films were deposited on various substrates with thicknesses in the nm range. The sulphides are chemically microanalysed and the occupied volume determined by automatic image analysis.

In this work we present the results obtained using a portable system of Energy-Dispersive X-Ray Fluorescence EDXRF to characterize the chemical composition of the polychromatic ceramic and the pigments, used in the mural painting, of Cholula.

Chemical and isotopic characteristics of rainwater at Los Humeros geothermal field, PueblaMexico and surrounding areas; Caracteristicas quimicas e isotopicas del agua de lluvia en el campo geotermico de Los Humeros, PueblaMexico y zonas aledanas. Organochlorine pesticide levels in female adipose tissue from PueblaMexico. Later, to assess its conservation value, the total diversity of the park was compared with that from an external, unprotected site with similar vegetation structure.


In addition, for the pulsed LBW conditions, the material compositions were predicted to be, by themselves, ‘weldable’ according to the pulsed LBW weldability diagram. Las uniones soldadas de aceros inoxidables siempre presentan problemas por las modificaciones microestructurales que suceden en la zona afectada por el calor.

We present here geodetic observations suggesting that the surface faulting in Mexico City triggered by the Puebla earthquake occurred in areas already experiencing differential displacements. The resolutions on environmental impacts, license for atmospheric pollution prevention, concession title for exploitation and use of national waters, permission for wastewater discharging services, company registration for producing dangerous wastes and fulfillment of all conditions noted in the documents show the applicable environmental laws for the project have been followed.

Medicago polymorpha had the lowest digestibility, which coincided with higher concentrations of neutral and acid detergent fiber. This document presents results obtained during the nickel and gold electrodeposition process on AISI stainless steel and the morphology and thickness of each coating, their adhesion, hardness and conductivity values.

The highest tensile strength between Ti—6Al—4V and SS L between which pure copper was used as insert metal was acquired. Seismologic study of Los Humeros geothermal field, PueblaMexico. The control species, Vicia sativa was represented by two varieties, which maintained a high dry matter production at two locations, in one of them, matched by Melilotus albus.

Multitechnique characterisation of L surface states oxidised at high temperature in steam and air atmospheres. Further, the above mentioned properties are related to the E. Full Text Available The basic principle of friction welding is intermetallic bonding at the stage of super plasticity attained with self-generating heat due to friction and finishing at upset pressure.

Mc Phail traps and PET bottles were used in the experiment.

Likewise, we assume that Pahuateca’s participation was due to the attempt of the regional political leaders to execute the mandates of the liberal state in terms that were locally acceptable; Osroio is to say, they elaborated a local agenda that provided political and social stability in the municipality based on the defense of the local autonomy, and not in the necessity of an agrarian claim.
