Last week, Mexico's state-owned oil company, Petroleos Mexicanos (Pemex), was scheduled to unveil plans for the sale of basic petrochemical plants. The first privatization package - Pemex ammonia plants at Cosoleacaque and Camargo - will involve the sale of securities on the Mexican Stock Exchange, allowing a large number of Mexican investors to acquire parts of the business

PEMEX: Incentives in a government-owned firm

Salas, F.J.

This dissertation analysis the capture of Mexico's oil company, PEMEX, through a historical overview of the Mexican oil industry and through a reference model of PEMEX's behavior. From this analysis, the dissertation will claim the following: (1) Due to the collective-action strength acquired by the PEMEX union in its initial decade (1938-1947) the government found it is less costly to co-opt union leaders than to negotiate with a militant union. The costs of this arrangement have increased ever since. Chapters 2 through 4 contain discursive and historical arguments to sustain this claim. (2) When the government's co-optation model can account for overmanning (more generally, relative factor input distortions) but fails to explain promotion practices based on union militancy, or for the relative decline of tenured contracts (Chapters 5 and 6). Based on the historical understanding of operational features and the incompleteness of the co-option model, one can draw that PEMEX does not operate on the (minimum) cost function. Therefore, PEMEX's sources of inefficiency go beyond overmanning and subcontracting distortions (Chapter 7). This dissertation concludes that governmental operation of an extractive industry in the form of a monopoly does not efficiently transfer to taxpayers their ownership rights to subsoil rents

The Pemex's future is unknown. The Mexican enterprise (state-owned oil monopoly) has problems in the following aspects: operative, financial, administrative and labour. The deposits decrease with regard to the productivity, in fact, the confines production is worrisome. This is the moment of asking what is it going to happen with Pemex with regard to its current structure, and then to accept that the answer would be not the wanted one. [Spanish] El futuro de Pemex es incierto. La empresa estatal monopolica mexicana presenta problemas en los ambitos operativo, financiero, administrativo y laboral.

1992-01-01

This paper reports that Petroleos Mexicanos and Shell Oil Co. have signed a memorandum of understanding to form a joint refining venture involving Shell's 225,000 b/d Deer Park, Tex., refinery. Under the agreement, Mexico's state owned oil company is to purchase a 50% interest in the refinery, and Shell is to sell Pemex unleaded gasoline on a long term basis. Under the venture, Shell and Pemex plan to add undisclosed conversion and upgrading units tailored to process heavy Mexican crude. The revamp will allow Pemex to place more than 100,000 b/d of Mayan heavy crude on the U.S. market. Mayan accounts for 70% of Mexico's crude oil exports. In turn, Shell will sell Pemex as much as 45,000 b/d of unleaded gasoline to help meet Mexico's rapidly growing demand

1994-01-01

Mexico's government this year will introduce petroleum tax reforms that will transform how its state owned petroleum company approaches capital spending. Effective Jan. 1, 1994, the Mexican government began to implement a revamped tax regime designed to accompany the breakup of Petroleos Mexicanos into four new operating subsidiaries. Each of the four new companies -- Pemex Exploration and Production, Pemex Refining, Pemex Natural Gas and Basic Petrochemicals, and Pemex Secondary Petrochemicals -- will be responsible for paying a new income tax. Levies on E and P will be tied to a ring-fence mechanism tailored after the scheme employed by the U.K. and Norwegian governments in the North Sea. The paper discusses the affected investment rationale, the North Sea ring-fence model, other tax changes, and shifting the burden

Hernandez, C.E.R.

2002-01-01

In this paper, the author reviewed the energy management activities, over the last two years, of Petroleos Mexicanos, also known as Pemex. These activities generated substantial savings. A brief overview of Pemex was provided. The State Oil Company of Mexico, Pemex occupies the third rank of the world oil producers, and is in seventh place in terms of proven reserves. The gas production has earned the company the ninth spot, and it is in tenth place as far as its refining capacity is concerned. Pemex has annual revenues of 50, 000 million American dollars and operates in excess of 1,000 facilities. The energy management program implemented covered an experts network, training, campaigns, and information and monitoring system. Each of the components of the energy management system were reviewed. Linking each facility, the experts network was created to enhance the efficient use of energy. The Energy Saving and Environmental Protection campaign was held over the period 1999-2000 and involved the participation of 209 work sites. For its part, the Energy Efficient Use and Savings campaign took place in 2000-2001, involving 205 work sites. Both resulted in substantial savings. An internal carbon dioxide trading system was also implemented to improve air quality, and was designed to provide a cap and trade carbon dioxide emissions. The next phase involved the implementation of an information and monitoring system, which defined an Energy Consumption Index used in monthly reports. The next steps in the process were briefly outlined. 5 figs

Although there exist the conditions and reasons to let Pemex become a trully state owned, commercialy oriented, oil company, in reality Pemex does not behave as such, due to the limitations posed by its legal framework. Such legal framework poses severe limitations to Pemex’s capacity in making the decisions which would enable it to perform in its fullest commercial potential. Pemex’s transformation into a true publicly owned company does not require it to abandon its structure of public law ...

Quantifying Pemex E and P benefits from foreign strategic associations

International Nuclear Information System (INIS)

Baker, G.

1993-01-01

The recent critique by the Heritage Foundation of the management of Mexico's petroleum sector deserves attention by oil industry observers of Mexico as well as government and academic analysts. The foundation argues that sweeping changes are needed-for Mexico's own good-in upstream and downstream policy. The following analysis presents one form of quantifying the upstream argument: the Mexican government stands to gain $5.7 billion/year in taxable revenue from state petroleum company Petroleos Mexicanos by 2000 from strategic associations with international petroleum companies. In addition, there are efficiency advantages that Pemex would gain by strategic associations with international petroleum companies. The ripple effects would include not only oil production and tax revenue increases from Pemex operations but also the advantages of new management skills, new sources of funding and technology, and lower operating and overhead costs in Pemex. It will not be possible, however, for the Mexican government to choose one or more strategic partners by quantitative methods alone. To the contrary, a significant measure of trust will be required

Oil fiscal regimes and national oil companies: A comparison between Pemex and Petrobras

Ramírez-Cendrero, Juan M.; Paz, María J.

2017-01-01

Analysis of the determinants of the performance of national oil companies (NOCs) is and has always been among the most discussed topics in specialized literature. In this context, the uneven path experienced by two major Latin American NOCs – Petrobras and Pemex – is striking. Our work seeks to explain the uneven performance, focusing on the productive aspects. In particular, we analyze the oil fiscal regimes in Brazil and Mexico as a very crucial aspect – though not the only one – within oil-rich countries that may shed light on the disparities between Petrobras and Pemex. The contribution of our work to the existing literature derives from the relationship that we establish between the characteristics of the respective oil fiscal regimes and the productive performance of the two NOCs, with special consideration paid to the ways in which a fiscal regime contributes, or not, to promoting and guiding the investment efforts of companies. We compare investment, production, and reserve indicators of Pemex and Petrobras and conclude that the Mexican and Brazilian oil fiscal regimes can largely explain the productive and investor performance of both NOCs. - Highlights: • We analyze the oil fiscal regimes in Brazil and Mexico. • We outline the major features in both national oil companies, Petrobras and Pemex. • We compare investment, production, and reserve indicators of Pemex and Petrobras. • We conclude that the OFRs largely explain the productive performance of the NOCs.

The nature of the industrial activities of PEMEX-REFINACION aimed at the energy production area in the refineries of the system, requires for its operation of an energy consumption that represents a highly significant amount among its total operation costs. These energy costs are being reduced in figures higher than 50% in 1990 to 43% in 1993 through coordination programs and investments oriented to the efficient use of energy and losses control. This paper presents the historical description of the developments, advances and achievements that have been obtained up to date in this subject in the production plant of PEMEX-REFINACION, beginning with the intensification of the program of energy conservation and efficient use of energy in 1990. As a substantial part of this paper the different actions being applied are listed right from the beginning of the program with their corresponding cost-benefit analysis, in order to eliminate the energy wastes that correspond fundamentally to short term measures requiring minimum investments and medium term actions with moderate investments. Likewise, the plan of action to be implemented is presented for the operation optimization of the system and the existing equipment, with the long term actions that for their execution require of large investments.

Chicxulub Impact Crater and Yucatan Carbonate Platform - PEMEX Oil Exploratory Wells Revisited

Pérez-Drago, G.; Gutierrez-Cirlos, A. G.; Pérez-Cruz, L.; Urrutia-Fucugauchi, J.

2008-12-01

Geophysical oil exploration surveys carried out by PEMEX in the 1940's revealed occurrence of an anomalous pattern of semi-circular concentric gravity anomalies. The Bouguer gravity anomalies covered an extensive area over the flat carbonate platform in the northwestern Yucatan Peninsula; strong density contrasts were suggestive of a buried igneous complex or basement uplift beneath the carbonates, which was referred as the Chicxulub structure. The exploration program carried out afterwards included a drilling program, starting with Chicxulub-1 well in 1952 and comprising eight deep boreholes through the 1970s. An aeromagnetic survey in late 1970's showed high amplitude anomalies in the gravity anomaly central sector. Thus, research showing Chicxulub as a large complex impact crater formed at the K/T boundary was built on the PEMEX decades-long exploration program. Despite frequent reference to PEMEX information and samples, original data and cores have not been openly available for detailed evaluation and integration with results from recent investigations. Core samples largely remain to be analyzed and interpreted in the context of recent marine, aerial and terrestrial geophysical surveys and the drilling/coring projects of UNAM and ICDP. In this presentation we report on the stratigraphy and paleontological data for PEMEX wells: Chicxulub- 1 (1582m), Sacapuc-1 (1530m), Yucatan-6 (1631m), Ticul-1 (3575m) Yucatan-4 (2398m), Yucatan-2 (3474m), Yucatan-5A (3003m) and Yucatan-1 (3221m). These wells remain the deepest drilled in Chicxulub, providing samples of impact lithologies, carbonate sequences and basement, which give information on post- and pre-impact stratigraphy and crystalline basement. We concentrate on stratigraphic columns, lateral correlations and integration with UNAM and ICDP borehole data. Current plans for deep drilling in Chicxulub crater target the peak ring and central sector, with offshore and onshore boreholes proposed to the IODP and ICDP

Hydrogeology of the Salamanca area, Cattaraugus County, New York

Zarriello, Phillip J.

1987-01-01

The hydrogeology of a 132-sq mi area centered at Salamanca, NY, is summarized in five maps at 1:24,000 scale. The maps show locations of wells and test holes, surficial geology and geologic sections, water-table surface, soil permeability, and land use. The valley-fill aquifer in the Salamanca area serves approximately 7,000 people through two major distribution systems with an average daily pumpage of 1.2 million gal/day. The aquifer, composed of outwash sand and gravel, averages 60 ft in thickness and overlies as much as 200 ft of lacustrine silt and clay. The aquifer is recharged directly from precipitation and through seepage from streams. Average annual recharge to the aquifer from direct precipitation and infiltration of runoff from adjacent hillsides is estimated to be 13 inches or 0.6 million gal/day/sq mi. The glacial features in the Allegheny valley near Salamanca are associated with Illinoian and Wisconsin glaciations. Illinoian features consist of small, isolated exposures of outwash and till emplaced against the valley walls. Wisconsin features deposited during Altonian and Woodfordian Times of the Wisconsin consist mainly of end moraines and valley-train outwash. (USGS)

Chicxulub impact crater is the best preserved of the three large multi-ring structures documented in the terrestrial record. Chicxulub, formed 65 Ma ago, is associated with the Cretaceous/Tertiary (K/T) boundary layer and the impact related to the organism extinctions and events marking the boundary. The crater is buried under Tertiary sediments in the Yucatan carbonate platform in the southern Gulf of Mexico. The structure was initially recognized from gravity and magnetic anomalies in the PEMEX exploration surveys of the northwestern Yucatan peninsula. The exploration program included eight deep boreholes completed from 1952 through the 1970s. The investigations showing Chicxulub as a large complex impact crater formed at the K/T boundary have relayed on the PEMEX decades-long exploration program. However, despite frequent use of PEMEX information and core samples, significant parts of the database and cores remain to be evaluated, analyzed and incorporated with results from recent efforts. Access to PEMEX Core Repository has permitted to study the cores and collect new samples from some of the boreholes. We analyzed cores from Yucatan-6, Chicxulub-1, Sacapuc-1, Ticul-1, Yucatan-1 and Yucatan-4 boreholes to make new detailed stratigraphic correlations and petrographic characterization, using information from PEMEX database and the recent studies. In C-1 cores, breccias show 4-8 cm clasts of fine grained altered melt dispersed in a medium to coarse grained matrix composed of pyroxene and feldspar with little macroscopic alteration. Clasts contain 0.2 to 0.1 cm fragments of silicate material (basement) that show variable degrees of digestion. Melt samples from C-1 N10 comes from interval 1,393-1,394 m, and show a fine-to-medium grained coherent microcrystalline groundmass. Melt and breccias in Y-6 extend from about 1,100 m to more than 1,400 m. Sequence is well sorted, with an apparent gradation in both the lithic and melt clasts. In this presentation we report on

The impact of Mexico's CRE regulation on Pemex marketing

International Nuclear Information System (INIS)

Martinez, A.

1997-01-01

The past, present and future of the natural gas industry in Mexico was reviewed. As far as the past is concerned, Pemex-Gas was a state monopoly, not subject to an independent regulatory authority. It was primarily concerned with providing natural gas to domestic consumers, it engaged in minimal marketing activities, and it was highly centralized. In the country as a whole, there was a notable indifference to regulation, and an almost total absence of a regulatory culture. Natural gas was seen as a minor byproduct of petroleum, not as an engine of economic growth. Reforms introduced in May 1995 attempt to institute revolutionary changes by creating a federal regulatory commission, (Comision Reguladora de Energia, CRE for short), and strongly encouraging private sector involvement in the storage, transmission and distribution of natural gas, while reserving exclusive jurisdiction for exploration and production to the State. Provisions of the new natural gas legislation were explained, including the impact on transportation, distribution and retail sales by the State Gas company, Pemex-Gas, and its assigned leading role in bringing about the legislated changes. A fully functioning open access system is expected to be in place by November 1997

1992-01-01

This paper reports that the relaxation of prohibitions on the use of propane as a motor fuel has spurred sizeable business activity in carburetion and higher demand for LPG throughout Mexico and particularly in Mexico City. However, a number of unforeseen problems have developed that required tough, immediate solutions. After the alternative fuels project began at city hall in Mexico City, publicity spread nationwide, reportedly spurring conversion activity in many other cities. That led to additional demand for fuel of a magnitude that few people had anticipated. In order to assume control of the situation, the national oil company, Pemex, established an official LPG Motor Fuel Department on June 1. Operating in conjunction with the Ministry of Industry, the new department has been busy registering every major propane-powered fleet in the country. Most important, the rate of conversion work must now be pegged to the availability of fuel. It is believed that conversion activity has become more evenly paced since the new Pemex agency took over.over

Deep Drilling Into the Chicxulub Impact Crater: Pemex Oil Exploration Boreholes Revisited

Science.gov (United States)

Fucugauchi, J. U.; Perez-Cruz, L.

2007-05-01

The Chicxulub structure was recognized in the 1940´s from gravity anomalies in oil exploration surveys by Pemex. Geophysical anomalies occur over the carbonate platform in NW Yucatan, where density and magnetic susceptibility contrasts with the carbonates suggested a buried igneous complex or basement uplift. The exploration program developed afterwards included several boreholes, starting with the Chicxulub-1 in 1952 and eventually comprising eight deep boreholes completed through the 1970s. The investigations showing Chicxulub as a large impact crater formed at the K/T boundary have relayed on the Pemex decades-long exploration program. Despite frequent reference to Pemex information, original data have not been openly available for detailed evaluation and incorporation with results from recent efforts. Logging data and core samples remain to be analyzed, reevaluated and integrated in the context of recent marine, aerial and terrestrial geophysical surveys and the drilling/coring projects of UNAM and ICDP. In this presentation we discuss the paleontological data, stratigraphic columns and geophysical logs for the Chicxulub-1 (1582m), Sacapuc-1 (1530m), Yucatan-6 (1631m) and Ticul-1 (3575m) boreholes. These boreholes remain the deepest ones drilled in Chicxulub and the only ones providing samples of the melt-rich breccias and melt sheet. Other boreholes include the Y1 (3221m), Y2 (3474m), Y4 (2398m) and Y5A (3003m), which give information on pre-impact stratigraphy and crystalline basement. We concentrate on log and microfossil data, stratigraphic columns, lateral correlation, integration with UNAM and ICDP borehole data, and analyses of sections of melt, impact breccias and basal Paleocene carbonates. Current plans for deep drilling in Chicxulub crater focus in the peak ring zone and central sector, with proposed marine and on-land boreholes to the IODP and ICDP programs. Future ICDP borehole will be located close to Chicxulub-1 and Sacapuc-1, which intersected

Mexico: Pemex caught between revolutionary heritage and the market

Rousseau, Isabelle

2016-01-01

Some constitutional modifications adopted in Mexico in 2013 marked an important watershed in the history and development of the Mexican oil industry: by opening this sector to private national or foreign investors, they make possible the emergence of an actual energy market. They also put an end to the monopoly of the Mexican public company, Pemex. In this article, the author proposes an historical perspective in order to better understand the influence of the Mexican Constitution of 1917 and of the oil industry nationalisation act of 1938 on the creation and development of the Mexican oil industry

Full Text Available ACCESSIBILITY AND USE OF URBAN GREEN SPACES IN THE CITIES OF COIMBRA (PORTUGAL AND SALAMANCA (SPAIN. In a society that values more and more wellbeing, health and free time, the introduction of urban green spaces (UGS next to residential areas has become a citizen’s right and requirement. This paper analyses the distribution and accessibility of UGS in the cities of Coimbra and Salamanca and evaluates their influence on the needs of the resident populations, in terms of users’ age, frequency of usage, as well as of motivation and ways to enjoy the facilities. In Coimbra there is a concentration of UGS, whereas in Salamanca there is a dispersion of such spaces, which has resulted in the different usage that people make of them. In fact, although Coimbra offers more urban green space (per inhabitant, their usage is reduced as people go there mainly by car, contrary to what happens in Salamanca. Consequently, Coimbra’s inhabitants choose these green spaces because of the activities they can be used for, whereas Salamanca’s inhabitants choose them for their proximity.

Organ builders, musicians and entrepreneurs: the De- Bernardi’s family in Salamanca, 1903-1932

Full Text Available In the early 20th century, Salamanca hosted one of the most culturally and musically active families of the city during the first three decades of the century: the De- Bernardis. Their activities as organ builders, musicians, teachers and music entrepreneurs, focused on the figures of Juan De-Bernardi and his son Luis, left a mark not only in the town, through their involvement in numerous cultural events, but also building and reparing various instruments in an area that covers from the North of Portugal to the South of Cáceres. Here we reconstruct, through the information given by local hemerographic sources, their trajectory from their arrival in Salamanca in 1903 until 1932.

MOOCs to internationalize Masters. A case study at the University of Salamanca

Science.gov (United States)

Pereira, Dolores; Recio, Marian; Perez, Ana Victoria; López, Santiago; Palacios, Esther

2015-04-01

Current major objectives of Master's degrees taught at the University of Salamanca are to incorporate multidisciplinary skills and to address international issues. It is important to ensure that students and early career scientists have all of the necessary skills to deal with professional development before career planning whether in academic research, professional practices or alternative careers, whether in Spain or elsewhere. However, many students choose a Master's programme without sufficient understanding of what they might need to deal with. A multidisciplinary degree course at the University of Salamanca, linked to the Institute of Social Studies for Science and Technology, focuses on training potential experts equipped to mediate between participants in science and technology and the wider public. Students participating in this course currently come from Spanish speaking countries. Because the course is taught mainly in Spanish, subsequent outreach might also be confined to Spanish speaking communities. Even so, it is essential to properly explain, at the outset, the aims of the Master's programme and the international potential of the qualification to attract more. Here we propose the use of MOOCs (Massive Open Online Courses) both to help students to know about the content and other details of the Master program before they join in and to internationalize the course to reach more potential interested students in the subject. This will be the first experience implementing MOOCs in the teaching of masters at the University of Salamanca and, if successful, the experience can be applied to other masters and courses in need of students and internationalization.

A review of Spanish uranium resources and recent developments in the province of Salamanca

International Nuclear Information System (INIS)

Gonzalez Granda, J.A.; Ruiz Sanchez-Porro, J.; Aranaiz Guezala, J. De

1997-01-01

Uranium exploration activities in Spain carried out during the 1950-1992 period, led to the discovery of a number of deposits in different geological environments. Presently there is only activity at the FE area in Salamanca province, where the only remaining mining centre is located. A new dynamic leaching processing plant with a capacity of up to 950 t U 3 O 8 t/year began operation in 1993, at FE mine. The development and planning of the mining in the open pits of ENUSA (province of Salamanca, Spain) under the present low market prices, has led to the implementation of a working scheme, based on the following concepts: Detailed knowledge of the distribution and quality of the mineralization by sufficiently close spaced drilling, with 3D positioning and grade estimation by deviation and gamma ray probing. Use of either geostatistical or arithmetical grade interpolation techniques, properly validated with production, adapted to the density of the information available. Economic optimization of the open pit, by means of the 3D Lerchs-Grossmann technique, as a guide for the final pit design. Calculation of the optimal pit shapes and recoverable resources under different price conditions. These techniques implemented by means of computerized data acquisition and processing systems, are used to face with versatility, the present economic conditions. A full review of the uranium deposits in the province of Salamanca is being carried out with these means. (author). 18 figs

García, A.

1991-08-01

Full Text Available This paper describes the results of 77 chemical analyses of groundwater from springs and wells in the «Complejo Esquisto Grauváquico» and other paleozoic materials from the south of Salamanca province. The types of groundwater are very diverse, usually bicarbonate dominant, with TDS (Total Dissolved Solids between 0.6 and 16 milimoles/l. Salinity is shown to be greater in the drilled wells than in the dug wells and springs, which confirms the existence of deep flow. Principal Component Analysis indicates that the chemical composition of groundwater must be the result of multiple reactions between the water and the minerals that occur in parallel, with none of the reactions being specially predominant. The organization and geographic distribution of sorne of the elements suggest the existence of regional flow systems.Se presentan los resultados de 77 análisis químicos de aguas subterráneas procedentes de manantiales, pozos excavados y sondeos en el Complejo Esquisto Grauváquico y otros materiales paleozoicos al Sur de la provincia de Salamanca. Se trata de aguas muy dispares, en general bicarbonatadas mixtas, con TSD (total de sólidos disueltos entre 0,6 y 16 milimoles/l. Se pone de manifiesto una mayor salinidad de las aguas de sondeos en relación con las de pozos y manantiales, lo que demuestra la existencia de una circulación a cierta profundidad. El análisis de componentes principales muestra que la composición química de las aguas debe ser el resultado de múltiples reacciones entre el agua y los minerales que se producen en paralelo, sin que destaque ninguna en especial. La distribución geográfica ordenada de algunos elementos obliga a plantear como posible la hipótesis de la existencia de un flujo regional.

In Colombia, the natural national parks are par excellence the scenarios to protect the ecological integrity of the ecosystems and consequently for the conservation of the fauna, flora, diversity, genetic resources and values cultural and historical associates. Contrarily, these protected areas are subjected to the degradation caused by anthropic processes and natural that which goes in detriment of the benefits and services that provide to the society. The same as the other protected areas belonging to the system of natural national parks (SNNP), the park road Island of Salamanca (VPIS) it has been subject to the degradation, which has been generated mainly by factors of anthropic character that they have caused an environmental imbalance of great space and temporary magnitude whose repercussion is significant for the fragility of the ecosystems of the protected area in its particular context and for the importance of its function in the region of the complex estuary of the Magdalena River

Villamayor stone is an arkosic stone of Middle Eocene age and belongs to the Cabrerizos Sandstone Formation that comprising braided fluvial systems and paleosoils at the top of each stratigraphic sequence. The sandstone is known by several names: i) the Villamayor Stone because the quarries are located in Villamayor de Armuña village that are situated at 7 km to the North from Salamanca city; ii) the Golden Stone due to its patina that produced a ochreous/golden color on the façades of monuments of Salamanca (World Heritage City,1988) built in this Natural stone (one of the silicated rocks utilised). We present in this work, the Villamayor Stone to be candidate as Global Heritage Stone Resource. The Villamayor Stone were quarrying for the construction and ornamentation of Romanesque religious monuments as the Old Cathedral and San Julian church; Gothic (Spanish plateresc style) as the New Cathedral, San Esteban church and the sculpted façade of the Salamanca University, one of the oldest University in Europe (it had established in 1250); and this stone was one of the type of one of the most sumptuous Baroque monuments is the Main Square of the its galleries and arcades (1729). Also, this stone was used in building palaces, walls and reconstruction of Roman bridge. Currently, Villamayor Stone is being quarried by small and family companies, without a modernized processing, for cladding of the façades of the new buildings until that the construction sector was burst (in 2008 the international economic crisis). However, Villamayor Stone is the main stone material used in the city of Salamanca for the restoration of monuments and, even in small quantities when compared with just before the economic crisis, it would be of great importance for future generations protect their quarries and the craft of masonry. Villamayor Stone has several varieties from channels facies to floodplains facies, in this work the selected varieties are: i) the fine-grained stone

Mining and processing of uranium deposits in Salamanca, Spain

Gomez Jaen, J.P.; Otero, J.; Serrano, J.R.; Membrillera, J.R.; Josa, J.M.

1977-01-01

In July, 1974, Empresa Nacional del Uranio, S.A. (ENUSA), took the decision to mine uranium in the province of Salamanca, based on geological and processing studies carried out by the Junta de Energia Nuclear (JEN). The milling plant was designed by JEN and assembled by ENUSA, and operations were begun on 22 May, 1975. The orebody, FE-1, is composed of slate of Cambrain age and the fissures are filled by primary minerals. Secondary minerals are impregnated in the zone affected by the hydrostatic level. The orebody is of the stockwork type in which carbonaceous matter has acted as a reducing agent. The average grade of the ore is 0.09% U 3 O 8 at a cutoff grade of 0.02% U 3 O 8 : the deposit is therefore among the lowest-grade deposits that are currently mined. Annual production is 1 200 000 t of rock, of which 200 000 t is ore-bearing. The milling plant uses a static heap-leaching method, followed by solvent extraction (tertiary amines) and precipitation by ammonia. Joint studies by JEN and ENUSA have led to the introduction of modifications that have increased the production capacity from 75 to 112 t U 3 O 8 per annum with no significant alteration in the initial planned investment. The total recovery after processing is 75% of the U 3 O 8 contained in the ore. Approximately 100 people are employed in the overall operation. ENUSA has decided to expand operations in Salamanca with the construction of a new milling plant (technological aid by JEN), which will be capable of processing 825 000 t of ore per year, with an annual production of 500 t U 3 O 8 . The new plant is expected to begin operations in 1979. (author)

To evaluate the results of the Pervasive Developmental Disorders (PDD) screening program currently ongoing in the public health services in the health area of Salamanca and Zamora, Spain, in terms of feasibility, reliability and costs, with the purpose of extending the program at regional and national levels. A total of 54 paediatric teams (nurses and paediatricians) from the provinces of Salamanca and Zamora participated in the training sessions for the PDD Screening Programme in September 2005, and agreed to administer the questionnaire M-CHAT(1) to all parents attending their clinics in any of these two visits: 18 months and/or 24 months within the Well-baby Check-up Program. A total of 9,524 children have participated up to December 2012. Additionally, we evaluated the participation and opinions of the paediatric teams using questionnaires, and costs per positive case have estimated. Out of a total of 852 (8.9%) children determined as PDD high-risk with the M-CHAT questionnaire results, 61 (7.1%) were confirmed as positive with the M-CHAT follow-up interview. Of these, 22 were diagnosed with a PDD and 31 other disorders of childhood onset according to DSM-IV-TR(2). Almost three-quarters (74%) of respondents felt the program was totally feasible, and 22% viable, but with reservations (n=54). This study has been able to show for the first time in Spain, the feasibility of a population-based PDD screening program within the public health system. Training in social and communicative development, and dissemination of the early signs of PDD among paediatricians, as well as the use of the M-CHAT, is essential for progress in the early detection of these disorders.

Roman Togatus Statue Found in Salamanca

Directory of Open Access Journals (Sweden)

Manuel Carlos JIMÉNEZ GONZÁLEZ

2016-11-01

Full Text Available We disclose the finding, during a recent archaeological work in the city of Salamanca, of two marble fragments belonging to a statue of a togatus, which we believe could have been part of the decorative and propagandistic program of the forum in the time of the Early Empire. The data that we have about the location and layout of the forum and the various public spaces and buildings that formed it are indeed very limited. The location of this sculpture would confirm and might even provide some more information in this regard. The discovery was made out of archaeological context, because there is no historical stratigraphic sequence in the basement of the site where it appeared, the material and formal characteristics that can be seen in sculpture, along with the space in which it was found, as well as the archaeological context of the area in a broader sense, allow some clarifications on a number of aspects of formal, chronological and interpretive order relating to it.

The consumption and production of the electrical energy contribute to the gas emission that has the property of retaining heat in the atmosphere, giving rise to an increment in the global average temperature of the Earth, and causing a climatic change that the international scientific consensus describes as important alterations in the meteorological patterns. As a result of this, international actions were taken. The most ambitious agreement and by its quantified and obligatory character is presented the Kyoto Protocol, that forces the countries listed in Annex 1 to reduce their emissions through national measures and flexible mechanisms, within these last ones is the Clean Development Mechanism (CDM) that contemplates the mutual cooperation between developed and developing countries in the participation of projects tending to the reduction of gas emissions of greenhouse effect. Petroleos Mexicanos (PEMEX) has large necessities of electrical energy and steam, and counts on projects with characteristics that under the CDM cover the characteristics to be technical and economically viable.

A raiz de esto, se tomaron acciones internacionales. El acuerdo mas ambicioso y por su caracter cuantificado y obligatorio lo representa el Protocolo de Kyoto, quien obliga a los paises listados en el Anexo 1 a reducir sus emisiones a traves de medidas nacionales y mecanismos flexibles, dentro de estos ultimos se encuentra el Mecanismo de Desarrollo Limpio (MDL) que contempla la cooperacion mutua entre paises desarrollados y en vias de desarrollo en la participacion de proyectos tendientes a la reduccion de emisiones

By comparing the temperature series in an urban area and those from a nearby rural area, we studied the temporal evolution of the intensity of the UHI for the three-year period between 1996 and 1998. We detected two phenomenons: nocturnal heat island, when the difference of temperature between city and rural zone is positive, and diurnal heat island, when is negative. The most intense nocturnal heat island was seen in autumn, and the most intense diurnal heat island was seen in spring. Statistical study of the annual series corresponding to the night-time heat island permits a definition for Salamanca: a weak island, such as the one showing an intensity lower than 2.0 oC, a moderate island, if the intensity lies between 2.0 oC and 4.0 oC, and an intense island when a values greater than 4.0 oC is passed.En este trabajo se ha determinado la existencia de la isla de calor urbana (ICU, en una ciudad de tamaño medio, con un clima extremado y focos industriales de poca actividad. Con lo que se puede comprobar cómo afecta el calentamiento urbano a ciudades de estas características, pudiendo influir en los seres vivos de la zona. La existencia del fenómeno isla de calor, y su evolución en el tiempo, se han observado comparando los datos de temperatura registrados en una estación meteorológica situada en la ciudad, con los de otra estación fuera del radio de acción de la urbe, durante el período 1996-1998. Se han detectado dos fenómenos: la isla de calor nocturna, cuando la diferencia térmica entre la ciudad y la zona rural es positiva, que presenta sus valores más altos en otoño, y la isla de calor diurna, cuando la diferencia es negativa, que

Full Text Available La importancia de las usurpaciones de tierras sufridas por el Concejo de Salamanca en sus términos y jurisdicción a lo largo del siglo XV quedó claramente demostrada con la publicación de N. Cabrillana, quien a partir de una rica documentación procedente del Archivo de la Biblioteca Nacional de Madrid, sacó a la luz un problema prácticamente desconocido hasta ese momento. Otras publicaciones posteriores, basadas en noticias aportadas por el Archivo Municipal de Salamanca, han complementado aquella aportación decisiva, aunque sin poder disponer nunca de un documento del alcance de la Pesquisa utilizada por Cabrillana; ni siquiera de un cuerpo de documentos homogéneo que permita medir y valorar de forma global la incidencia del fenómeno usurpador. Sin embargo, nadie duda de la trascendencia que éste tiene para la historia socioeconómica, e incluso paisajística, de la provincia de Salamanca. Este interés nos mueve a presentar ciertos datos y documentos recogidos en el siempre sorprendente Archivo de nuestro municipio, para intentar llegar un poco más allá en el conocimiento de las enajenaciones de tierras concejiles.

We report a study on the contents of airborne pollen in the city of Salamanca (Spain) aimed at establishing a pollen calendar for the city for the yearly periods of maximum concentrations, relating these with quantifiable atmospheric variables over two two-year periods with an interval of 10 years between them: 1981-82 and 1991-92. The pollen was captured with Burkard spore-traps, based on Hirst's volumetric method. Determinations were made daily and were used to make preparations, previously stained with basic fuscin, for study under light microscopy at x 1,000 magnification. 946 preparations were analyzed, corresponding to the same number of days distributed over 150 weeks of the periods studied. The results afforded the identification of 48 different types of pollen grain: Grasses (Poaceae), Olea europea (olive), Quercus rotundifolia (Holm-oak), other Quercus spp. (Q. pyrenaica, Q. suber, Q. faginea, etc.), Cupressaceae (Cupressus sempervivens, C. arizonica, Juniperus communis etc.), Plantago (Plantago lanceolata, Plantago media, etc.), Pinaceae (Pinus communis, Abies alba, etc.), Rumex sp.

Hurtado-Cardador, Manuel; Urrutia-Fucugauchi, Jaime

Since 1947 Petroleos Mexicanos (Pemex) has conducted oil exploration projects using potential field methods. Geophysical exploration companies under contracts with Pemex carried out gravity anomaly surveys that were referred to different floating data. Each survey comprises observations of gravity stations along highways, roads and trails at intervals of about 500 m. At present, 265 separate gravimeter surveys that cover 60% of the Mexican territory (mainly in the oil producing regions of Mexico) are available. This gravity database represents the largest, highest spatial resolution information, and consequently has been used in the geophysical data compilations for the Mexico and North America gravity anomaly maps. Regional integration of gravimeter surveys generates gradients and spurious anomalies in the Bouguer anomaly maps at the boundaries of the connected surveys due to the different gravity base stations utilized. The main objective of this study is to refer all gravimeter surveys from Pemex to a single new first-order gravity base station network, in order to eliminate problems of gradients and spurious anomalies. A second objective is to establish a network of permanent gravity base stations (BGP), referred to a single base from the World Gravity System. Four regional loops of BGP covering eight States of Mexico were established to support the tie of local gravity base stations from each of the gravimeter surveys located in the vicinity of these loops. The third objective is to add the gravity constants, measured and calculated, for each of the 265 gravimeter surveys to their corresponding files in the Pemex and Instituto Mexicano del Petroleo database. The gravity base used as the common datum is the station SILAG 9135-49 (Latin American System of Gravity) located in the National Observatory of Tacubaya in Mexico City. We present the results of the installation of a new gravity base network in northeastern Mexico, reference of the 43 gravimeter surveys

Granites of Salamanca. A perfect example for the recognition of natural stone as a heritage resource and their use in restoration

In the province of Salamanca (Spain) there are several quarries that used to be the source of natural stone used in the construction of historic buildings and that are today recognized by UNESCO as World Heritage Sites. In this study we investigated the granites used in the construction and restoration of the lower ashlars of the walls of different buildings in Salamanca, Alba de Tormes, Ciudad Rodrigo and Ledesma. The characterization of the different types of granite and their current state of preservation may serve to adopt specific measures for their possible use in the restoration of the architectural heritage of the province, if this should become necessary. Despite the variety of materials observed in the lower parts of the buildings (ranging from sandstone to conglomerate to granite), the stone most frequently used was the granite from Los Santos and the Martinamor granite, followed by the vaugneritic granites from Ledesma. In general the granite materials are in a good state of conservation but the existence of certain pathologies that have given rise to processes of flaking and discoloration of the rock suggests that it will be necessary to make a consistent assessment when deciding about possible actions aimed at replacing materials in these historic buildings Moreover, the various granites differ from one another and pieces should not be replaced without perfect identification of the specific type to which they belong. A detailed study of these granites is crucial for the nomination of some of them as candidates for the denomination Global Heritage Stone Resource and the whole set of Salamanca province lithologies as a Global Heritage Stone Province.

Full Text Available Se cumplieron recientemente los cien años de la venida de don Miguel de Unamuno a Salamanca. Al cabo de este centenario queremos rendir nuestro pequeño homenaje al rector del Estudio salmantino evocando las relaciones entre el escritor vasco y su tierra adoptiva. Por otra parte, sugerimos el aprovechamiento didáctico en el aula de un buen número de páginas de recuerdos, andanzas, visiones y querencias íntimas dedicadas por don Miguel a la ciudad y al campo de Salamanca. Niños y adolescentes de nuestra tierra pueden llegar a conocer literariamente a tan insigne escritor por medio de poemas y textos en prosa llamados a sellar con letras de oro la muy peculiar relación de Unamuno con los rincones y callejas de la ciudad, con las llanuras y cimas de su Castilla o con las verduras del Tormes. El autor de Niebla es también el hombre volcado en el paisaje que lo mece, el paisano que se lanza en busca de las gentes sencillas del campo procurando, al menos, su consuelo. Si la misión de despertar al dormido, ligada a obras mayores, queda especialmente reservada a los adultos, otros textos de don Miguel nos permiten llegar hasta los más jóvenes con versos y párrafos que hablan y cantan a los múltiples protagonistas de la intrahistoria. De este modo, podemos dar cuenta, con diligencia y sencillez, de un autor ilustre al tiempo que conocemos creaciones literarias concordantes temáticamente con la realidad que nos envuelve. La misma satisfacción halagadora que sentía Unamuno charlando con los viejos campesinos o leyendo a los gañanes consejas, cuentos y poesías, puede continuar en nosotros al proyectar en el aula sus estampas poéticas, su andanzas y visiones. A los deseos del rector de ser útil a la Escuela Normal de Salamanca, añadimos hogaño los nuestros propios de aprovechar pedagógicamente los lienzos literarios del poeta y paseante. Acaso, así, aprendamos todos a ver y sentir mejor los paisajes urbanos de la ciudad charra y sus

Full Text Available FUNDAMENTOS: Conocer el grado de contaminación por plomo, cadmio, cinc y arsénico de las aguas de la provincia de Salamanca y su relación con la zona de procedencia de las muestras y el punto de recogida de las mismas. MÉTODO: Estudio epidemiológico transversal, observacional y descriptivo. Se han estudiado aguas procedentes de redes de abastecimiento, fuentes, manantiales, pozos, ríos, riveras y lagunas de la provincia de Salamanca, analizándose los contenidos de plomo, cadmio, zinc y arsénico de 180 muestras, mediante espectroscopía de absorción atómica. Se han comparado los niveles de contaminación por los cuatro elementos de las muestras de agua entre las cuatro unidades comarcales de la provincia. Se han comparado los niveles de contaminación por los cuatro elementos entre las aguas procedentes de redes de abastecimiento y aquellas muestras de pozos, fuentes, manantiales y aguas de superficie. RESULTADOS: Los resultados indican que un 56% de las muestras analizadas superan las concentraciones máximas admisibles de cadmio, y un 28% del total de muestras analizadas supera las concentraciones máximas admisibles de plomo, según la legislación vigente presentando niveles tolerables de zinc y arsénico. No se han observado diferencias importantes en el grado de contaminación de las aguas por los elementos estudiados entre las cuatro unidades comarcales de la provincia. No se han observado diferencias en los niveles de contaminación por los cuatro elementos entre las aguas procedentes de redes de abastecimientos y aquellas muestras de pozos, fuentes, manantiales y aguas de superficie. CONCLUSIONES: Los resultados sugieren que las aguas de la provincia de Salamanca presentan de forma "natural" altos contenidos de cadmio y plomo, probablemente debido a las características geológicas del terreno.

Full Text Available In volume 12 of Cuadernos Dieciochistas Professor Pedro Álvarez de Miranda revealed the existence of an issue of the Continuación del Semanario de Salamanca, dated 19 April 1800, which included a Letter in defence of the translation by Leandro Fernández de Moratín of Shakespeare’s tragedy Hamlet.The Letter, signed by a mysterious P. Ozerín-Jáuregui y Z., attacks the Examen of Moratín’s volume published by the Mallorcan man of letters Cristóbal Cladera and sets out a series of objections which in effect defend the quality of the translation and the historical information accompanying it. The present article attempts to place the newly-discovered critical text in its literary and historical contexts, analyzing its arguments and approach, and evaluating its contribution to the on-going debate over the quality of Moratín’s Hamlet. The article includes, by way of appendix, an annotated transcription of the complete Letter as published in the Continuación del Semanario de Salamanca.

Full Text Available Objectives: To compare incidence, mortality and epidemiological characteristics of patients diagnosed with colorectal cancer (CRC in the province of Salamanca over two different periods: 2010-2012 and 2004-2006. Methods: Retrospective observational study. We include all diagnosed cases of CRC according to histopathological criteria from 01/01/2004 to 31/12/2006 and from 01/01/2010 to 31/12/2012. The studied variables were sex, age, date of diagnosis and tumor location. Cumulative incidence and specific incidence in different age groups were measured and compared between the two periods. The age rates were adjusted to the standard world population so that the results could be compared with those of other populations. Results: We detected 38% more cases of CRC in the 2010-2012 period than in 2004-2006. Variables distribution (sex, age at diagnosis and location was similar in both groups. More than twice as many colonoscopies were performed in 2010-2012 than in 2004-2006. Population mortality due to CRC also increased, although much less importantly than the incidence of this condition. Conclusions: There has been a clear increase in CRC incidence in the province of Salamanca from 2004-2006 to 2010-2012 which is not related to the ageing of the population. The remarkable increase in colonoscopies may have been an important factor for the increased detection.

Ten discussion groups, 2 composed of members of health-related associations and 8 primary care users, involved a total of 83 people. The structural variables considered are: gender, age, educational level and membership or not associations. Generate information to achieve information saturation in the discussion groups. Upon obtaining their informed consent, all subjects in the study participated in videotaped conversations, which were transcribed verbatim. Four researchers categorized the content, intentionality of discourse and developed the concept map. After categorization, triangulation and coding, content obtained was analysed with the NudistQ6 program. Informative content suggest four information needs: health and prevention, early diagnosis, first aid and disease. Different intentions (information needs, watching, claim and improvement) and needs profiles are detected as structural variables. Major information needs are relate to diagnosis, prognosis and therapeutic options. There is agreement between the groups that the information transmitted to the patient must be intelligible, updated and coordinated among the different professionals and care levels.

Full Text Available RESUMEN: El Colegio Menor de la Concepción de Huérfanos de la Universidad de Salamanca es uno más de la gran cantidad de colegios que se fundaron al amparo del estudio salmantino en el siglo XVI. Fundado por Francisco de Solís, obispo de Bagnorea y secretario de Paulo III, durante tres siglos facilitó y proporcionó amparo y educación a multitud de estudiantes pobres que no tenían recursos para ello. Fundado en la primera mitad del siglo XVI, durante esta centuria se asentó y comenzó su andadura, que terminaría en el siglo XIX. Este trabajo realiza un análisis sobre los primeros años de vida del Colegio, analizando cuestiones tan importantes como su fundación, las bulas fundacionales, el fundador, las primeras constituciones o la matrícula durante el siglo XVI, entre otras. Fue el siglo XVI el siglo de su nacimiento y consolidación, realizando durante esta centuria un gran esfuerzo institucional, como demuestra el hecho de la elaboración de las primeras constituciones, la construcción del edificio, o la incorporación a la Universidad de Salamanca, por ejemplo. A lo largo de estas páginas realizaremos un recorrido por los orígenes del primer colegio universitario que se crea para el amparo de niños pobres y huérfanos, permitiéndoles estudiar desde la gramática hasta graduarse en la ciencia que mejor les pareciere. La obra social y educativa del Colegio permitió la progresión y ascenso social de multitud de estudiantes pobres y huérfanos con talento, que de otra forma nunca hubieran podido realizar estudios en la Universidad, puesto que carecían de recursos para ello.ABSTRACT: The Conception of Orphans Minor College of the University of Salamanca is one more of the great quantity of colleges that were founded under protection of Salamancan Study in the 16th century. It was founded by Francisco de Solís, bishop of Bagnorea and secretary of Paulo III, provided protection and education to many poor students without

Full Text Available La Universidad de Salamanca está en el siglo XVI, en permanente estado de cambio. Desde principios del siglo, con los Reyes Católicos, hasta finales, bajo Felipe II, ese espíritu de renovación se hará patente de un modo continuo. Del interés de Isabel, reflejado en su visita de 1487, no vamos aquí a tratar; pero sí hemos de recordar que Fernando el Católico envió en 1512 al Obispo de Cuenca, Ramírez de Villaescusa, para tantear una reforma. En 1529, bajo el rectorado de Pérez de Oliva, asistimos a un proceso similar, cuya profundidad aun está discutiéndose. En 1538, en pleno reinado de Carlos V, se establecerán los famosos Estatutos que estarán vigentes durante más de veinte años. En 1550, el Consejo Real envía al Obispo de Coria, Diego Enríquez de Almansa, con el mismo intento reformador, como en el presente trabajo podremos comprobar.

Se ha comenzado por una descripción de las figuras que contiene el abrigo y que son en su mayoría arboriformes y antropomorfos, algunos de ellos con tocados u otros elementos suplementarios. En menor número: barras, ancoriformes, un cuadrúpedo y la aparición de cuatro motivos compuestos por elementos triangulares o subtriangulares y la parte superior de un antropomorfo. A continuación, estos motivos se han encuadrado en el resto del conjunto del arte esquemático, resaltando los elementos que poseen una mayor importancia, sea por representar motivos nuevos o característicos dentro del arte esquemático, sea por ser un elemento mayoritario del abrigo. Hemos terminado haciendo una correlación de este abrigo con los que a nuestro parecer poseen un mayor número de elementos de comparación en el resto de la Península.RÉSUMÉ: Nous faisons connaître par ce travail un nouvel abri d'art rupestre schématique dans la province de Salamanca, commune de Ciudad Rodrigo.

A este respecto, en la Biblioteca Universitaria de Salamanca se encuentra un volumen facticio constituido por un total de treinta y una obras en las que se refieren los sucesos más relevantes de la guerra de Sucesión. Su interés radica en que, además de ofrecer la interpretación popular de la contienda, su estudio permite, a través del Catálogo bibliográfico que aquí se ofrece, recuperar un material esencial para mejorar nuestro conocimiento de la literatura popular y de la imprenta dieciochesca.ABSTRACT: In the eighteenth century a significant number of blindman’s ballads had as their subject the monarchy, the large number of those dedicated to Philip V and their devotion to him being outstanding. ln this respect, the University Library of Salamanca has a factitious volume made up of a total of thirty-one works which relate the most relevant events of the War of the Spanish Succession. lts interest lies in the fact that, besides offering the popular interpretation of the conflict, its study makes it possible, through the bibliographic catabogue offered here, to recover essential material for improving our knowledge of the popular literature and eighteenth century printing.

Full Text Available In 2013 a new open air rock art site was discovered in the place called La Salud in the city of Salamanca. In 2014 we carried out an intensive survey to have a better knowledge. As a result, in three decorated sectors were distinguished containing in total four animal representations –two horses, a cervico-dorsal line and a possible goat– and several non figurative motives composed by crossed lines. Different preservation issues affecting the site, such as landslide and erosion, have probably hampered the conservation of more representations all along the valley. Despite the low number of figures, the technical and the formal procedures used in for these representations link directly La Salud site with other open air rock-art sites as Siega Verde and Foz Côa. This extents considerably the territory of these kind of representations revealing the necessity of more intense work to investigate the Upper Paleolithic habitat in the Meseta.

The therapeutical effectiveness of gestrinone in endometriosis treatment, as well as its long term side effects, were evaluated. Prospective, clinical trial. At "Dr. Alejandro Castanedo Kimball" Hospital (PEMEX). Salamanca, Guanajuato. México. Thirty women with laparoscopically confirmed endometriosis, were studied. Subjects received 2.5 mg. of gestrinone two times per week for 6 months. Laparoscopy was performed before treatment, and clinical response was determined by second laparoscopy after 6 months. The pregnancy rate, frequency of side effects and recurrence of symptoms were determined. Median total endometriosis scores and symptoms decreased significantly after treatment. Four pregnancies were observed after treatment. The principal side effects were: ponderal increase, changes in the voice and hirsutism. However, the side effects disappeared after one year of clinical survey. The results indicate that gestrinone is effective in the treatment of pelvic endometriosis. In despite of a clear benefic effect on stage of the disease and symptoms; the use of gestrinone should weigh the risk-benefit (cost versus metabolic side effects) of treatment.

Selective sandstone deterioration in the cathedrals of Salamanca, Textural anisotropy as a cause

1994-09-01

Full Text Available Textural sandstone anisotropy is related to the selective deterioration of such stone in buildings. The samples studied come from the Cathedrals of Salamanca. Stone fragments, cut in different directions with regard to the base supporting the ashlars in the wall, are studied by means of a binocular magnifying glass and the Scanning Electron Microscopy (SEM. This shows that the sandstone microfabric has a granular and a laminar microtexture, which correspond to different directions in the plane in question as regards the position of the ashlar. Either of these circumstances coincides with the stone surface on the outside of the building and affect its surface deterioration in a different way. The SEM images of deteriorated stone were compared with those of unaffected stone, with both types coming from differently orientated cuts as regards the position of the ashlar. In conclusion, the position given to the block of stone in the building is of importance for the preservation of the stone. The speed of ultrasound transmission measured in samples from commercial quarries confirms the textural sandstone anisotropy to a greater or lesser extent.

La anisotropía textural de las areniscas se relaciona con la selectividad de su deterioro en los edificios. Las muestras estudiadas pertenecen a las Catedrales de Salamanca. Fragmentos de piedra, cortados en direcciones diferentes respecto a la base sobre la que se asientan los sillares en el muro, son estudiados por medio de la lupa binocular y del microscopio electrónico de barrido (SEM. De éstos se deduce que la microfábrica de las areniscas tiene una microtextura granular y otra laminar, que corresponden a direcciones diferentes del plano respecto al asiento del sillar. Una u otra de estas situaciones coincide con la superficie de la piedra expuesta al exterior en el edificio, y afectan a su deterioro superficial de forma diferente.

Full Text Available En este trabajo se ha determinado la existencia de la isla de calor urbana (ICU, en una ciudad de tamaño medio, con un clima extremado y focos industriales de poca actividad. Con lo que se puede comprobar cómo afecta el calentamiento urbano a ciudades de estas características, pudiendo influir en los seres vivos de la zona. La existencia del fenómeno isla de calor, y su evolución en el tiempo, se han observado comparando los datos de temperatura registrados en una estación meteorológica situada en la ciudad, con los de otra estación fuera del radio de acción de la urbe, durante el período 1996-1998. Se han detectado dos fenómenos: la isla de calor nocturna, cuando la diferencia térmica entre la ciudad y la zona rural es positiva, que presenta sus valores más altos en otoño, y la isla de calor diurna, cuando la diferencia es negativa, que presenta sus valores más altos en primavera. Realizando un estudio estadístico de la evolución anual de la isla de calor nocturna en Salamanca, podemos definir isla de calor débil si su intensidad es inferior a 2 oC, moderada si se encuentra entre 2 oC y 4 oC e intensa si supera los 4 oC.

Su mera enumeración y referencia bibliográfica llenaría varias páginas, por lo que cabe afirmar que no es un tema desconocido para el especialista. Además, acoge la práctica totalidad de Escuelas Normales de toda la geografía hispana. En cuanto a la institución de referencia para este trabajo, la de Salamanca, es preciso afirmar que también va siendo estudiada en visiones de conjunto dentro del ámbito de Castilla y León, o en otras etapas históricas diferentes a la que ahora abordamos. Esta es, expresada de forma breve, la justificación de lo escrito a continuación: cubrir en cierta manera una pequeña laguna, al tiempo que contribuye a explicitar el rico movimiento pedagógico y normalista que vive la España liberal del tercio central del XIX. Podrá advertirse que se trata de un estudio institucional de carácter local, aunque encuadrado en la etapa histórica que venimos considerando de emergencia del sistema nacional-liberal de educación en España, y, por tanto, de creación y primera consolidación de las Escuelas Normales. Por ello, queremos aquí poner de manifiesto cómo el caso de Salamanca, situándose en un plano de realizaciones oscilantes, aunque comparativamente dignas, nace y subsiste en este período histórico dentro de un contexto mucho más amplio. También hemos de informar en este preámbulo sobre la dificultad en la búsqueda y tratamiento de fuentes. Las particulares del establecimiento son, para esta primera etapa de su vida, escasas y de no mucha significación documental. Sin embargo, aunque muy dispersas, sí son abundantes en otros archivos como el de la Diputación de Salamanca y el Archivo General de la Administración, o en boletines, prensa e informaciones

El arzobispo Fonseca le ofreció un puesto en el Colegio Mayor de Santiago el Cebedeo por él fundado. No aceptó el santo el ofrecimiento, por lo que, llegado a la ciudad del Tormes vestido como un pobre estudiante, se aposentó en una posada.Lo más probable es que ni siquiera llegase a matricularse en la academia salmantina, por más que el tardío claustro pleno de la Universidad del 4-VII-1624 llame a Ignacio «hijo de esta Vniversidad». Una iniciativa de los dominicos de San Esteban hizo que aquel candidato a estudiante de Salamanca diera pronto con sus huesos en la cárcel episcopal. Salido de ella, abandonó para siempre la ciudad camino de la Sorbona parisiense «llevando algunos libros en un asnillo».

To assess the view of a group of Primary care professionals on their level of perception of group cohesiveness in their teams' work dynamic. A descriptive and sectional study. Four urban health centres in Salamanca with a recognised teaching activity. Both health professionals and those outside the Health Service, working in Primary Care, who had been members of their teams for more than a year (N = 90). Descriptive statistics and "Chi squared" tests were employed. 72%. A high level of agreement on the need for team work (95.23%). They perceived their group cohesiveness as being very low (84.21% affirmed that they encounter problems of cohesiveness). The main statements concerning this lack of cohesiveness were: "lack of common objectives" (25.5%), "intolerance between workers" (20.13%), "work not shared" (19.46%) and "the taking of decisions individually" (19.44%). The main causes given were: lack of support from Management (23.74%) and too little training for team work (21.58%). There is a high degree of conviction that the team work model is the most efficacious way of developing Primary Care. However in three of the four teams questioned, there were serious problems preventing the teams' reaching an adequate level of group cohesiveness.

1980-01-01

In July 1974 ENUSA (the National Uranium Company) started mining operations in the FE-1 deposit in the municipal district of Saelices el Chico, Salamanca province. This is a deposit of the Stockwork type and is embedded in Cambrian shales of a distinct degree of metamorphism. The primary mineralization is found filling fissures and fractures of only slight longitudinal development. The secondary minerals were deposited in the zones affected by the hydrostatic level. The investigation of the deposit was carried out by the Spanish Nuclear Energy Board (JEN). In its final phases it consisted of a control drilling campaign and a wagon-drill campaign. The deposit was evaluated by the zone-of-influence method in accordance with the control drillings and the wagon drillings. The overall rate of production was 1,200,000 t per annum, of which 200,000 t were ore with a U 2 O 8 content of 0.08%. The output of the processing plant was 130 t U 3 O 8 . In 1976 ENUSA undertook a mining project of much greater scope in consequence of the decision to expand the ore processing plant (objective of the Quercus project). The annual output of the plant in question will be 600 t U 3 O 8 . For this the production of ore will be increased to 825,000 t/a (average grade 0.075%) and the total amount removed will be 9 million tonnes per annum. Account is taken of the whole of the FE deposit, which includes FE-1 and FE-3 and their respective extensions. The evaluation of the deposit was made both on the basis of the results of the control- and wagon-drillings and by the Kriging statistical method. (author)

Full Text Available El propósito de este artículo es examinar el material simbólico y los vínculos sociales entre la memoria colectiva, la identidad y el espacio de Salamanca, en el siglo XXI a través de la novela, Tierra Violenta, de Luciano G. Egido. Desde esta perspectiva, propongo una lectura del texto que nos ayude a entender cómo las circunstancias políticas y económicas determinan la estructura de la ciudad; que cambia, a su vez,  la vida de sus habitantes. Se trata de una ciudad que, aparentemente, vive en el pasado, pero que no es inmune a los mecanismos que rigen el siglo XXI. En esta aproximación, el texto literario es una fuente de distintas líneas de análisis para entender las temporalidades urbanas y la dialéctica de ambos, el proyecto público y  la herencia urbana.

Full Text Available RESUMEN: A manera de «elogio fúnebre» voy a dedicar estas páginas al muy antiguo y famoso sistema de oposiciones a cátedras universitarias en nuestro mundo hispánico. En Salamanca, desde época muy antigua, las cátedras se obtenían por oposición, que se realizaba según reglas muy complicadas. Es uno de los aspectos de la vida académica que más apasionaba los ánimos de los universitarios. Vibraba todo el cuerpo académico y hacía vibrar a la ciudad entera, que vivía al ritmo de la célebre Escuela. En ello la siguieron casi todas sus universidades hijas de Hispanoamérica, que heredaron las costumbres, virtudes y vicios de la Alma Mater. Al fin y al cabo «de tal palo tal astilla».

In this project, evaluation of plasma thermal process applied for degradation of hazardous waste was performed when the process was operated without oxigen, for degradation of oily sludge. Such wastes are produced from petroleum refineries and represent a problem due to the fact that they hazardous and great amount of them are generated in Mexico and the world; moreover there are not current with high efficiency to treat them. In this study the degradation experiments were made using two different sludge samples, one them was free of sediments, the bigger portion was water and hydrocarbons and the other sample was characterized by to had a high amount of sediments. These samples were obtained from a storing center of PEMEX. Process was operated utilizing different characteristics of the by-product. The biggest decrease in volume obtained with the sample of high amount of sediments was 85%, and such by-product resulted inert. For the sludge free of sediment the highest decrease of volume obtained was 95.5% and this by-product contained high amount of carbon in the form of dust, almost 50% of carbon mixes with clay material. The degradation efficiency of organic material was higher than to 99.99%. The residual gases formed during the degradation had low molecular weight.

1996-01-01

In Mexico, there are several environmental issues which are being addressed under the current governmental legislation. One of the important issues is restoring sites belonging to Petroleos Mexicanos (PEMEX). PEMEX is a large government owned oil company that regulates and manages the oil reserves. These sites are primarily contaminated with weathered hydrocarbons which are a consequence of extracting millions of barrels of oil. Within the southern regions of Mexico there are sites which were contaminated by activities and spills that have occurred during the past 30 years. PEMEX has taken the leadership in correcting environmental problems and is very concerned about cleaning up the contaminated sites as quickly as possible. The most significant contaminated sites are located to the north of Veracruz and south of Tabasco. These site areas are close to refineries or locations of oil exploration. The primary category of contaminants are hydrocarbons, among them asphaltenes, aromatic and other contaminants. The concentration of the contaminants varies depending on the location of the sites, but it can reach as high as 500,000 ppm. PEMEX has been searching for appropriate, and cost-effective technologies to clean up these sites. Biologically based remediation activities are of primary interest to PEMEX. However, other treatment technologies such as chemical-physical methods, encapsulation and incineration are also being considered. The present report summarizes preliminary experiments that measured the feasibility of bioremediation for a contaminated site in southern Mexico

Full Text Available The present work has developed a method using GIS technology to evaluate the danger, vulnerability, and exposure to the risk of flooding in the Alba de Yeltes area (Salamanca, Spain. It is a non-structural measure for the prevention and mitigation of the risk of extraordinary flooding. After completing a full analysis of the physical environment (climate, geology, geomorphology, hydrology, hydrogeology, and land use, hydrological-hydraulic modeling was carried out using the GeoHecRas river analysis software. The results obtained from the analysis and the models have generated a danger map that facilitates the efficient evaluation of the spatial distribution of the different severity parameters (depth of the watersheet, current flow rate, and flood-prone areas. Also, map algebra and the databases associated with GIS tools, together with the vulnerability and exposure cartography, have allowed the risk to be analyzed in an integrate manner and the production of an environmental diagnostic map. The results of this study propose that there are inhabited areas close to the Yeltes-Morasverdes riverbed that have a high risk of flooding, indicating the need for proper land planning and the implementation of a series of measures that will help to reduce the risk of flooding and its impact.

Full text: Activity concentrations of U ({sup 238}U, {sup 234}U) and Th ({sup 232}Th, {sup 230}Th) radionuclides in samples of superficial urban soils surrounding an industrial complex in Salamanca, Mexico have been determined. Levels of naturally occurring radionuclides (Norm) in the environment may be affected due to the presence of different industrial activities in this zone, representing a potential radiological risk for the population which should be evaluated. Alpha-particle Spectrometry with Pips detectors has been used for the radiometric characterization. A well established radiochemical procedure was used for the isolation of the radionuclides of interest. Alkali fusion for sample digestion, liquid-liquid extraction with Tbp (tri-butyl-phosphate) for U and Th isolation and electrodeposition in stainless steel dishes for measurement conditioning has been used. The results cover the ranges of 10-42, 12-60, 12-52 and 11-51 Bq·kg{sup -1} for {sup 238}U, {sup 234}U, {sup 230}Th, and {sup 232}Th respectively, being not observed any clear anthropogenic increments in relation with the values normally found in unaffected soils. Although there is disequilibrium between U isotopes and {sup 230}Th in some soil samples, it can be attributed to natural processes. The radiological impact of the industrial activities in the surrounding soils can be then evaluated as very low. Hence, from the Radiological Protection point of view, the soils studied do not represent a radiological risk for the health of the population. (Author)

Bone Paget's disease is heterogeneously distributed and several foci of high prevalence have been reported in Spain. The aim of the present work was to determine the prevalence of the disease in a zone situated in the northwestern sector of the Province of Salamanca (Spain) using a cross sectional epidemiological study. Sample choice was based on a stratified sampling according to the residence, age and sex of the inhabitants of the zone. A sampling error of 5% and a confidence level of 95% were considered; these afforded a sample of 378 units. Final choice of the subjects was based on a random pathway method. Data collection was accomplished with a personal interview using a 31-item questionnaire and analytical screening (AP and GGT). The field work was carried out over a one-year period. The data were input onto a calculation sheet for analysis and epidemiological interpretation. Finally, clinico-radiological confirmation of the cases deemed positive in the screening was accomplished. The prevalence of PBD in the zone studied is 5.7% (95% CI: 4.5-6.9). The highest percentage of patients lies within the age group between 70-79 years; most of these patients were women. The mean residence time in the zone was 66 years. According to the findings, this geographic zone has a high prevalence of PBD

This paper looks into various models that address strategic behavior in the supply of gas by the Mexican monopoly Pemex. The paper has three very strong technical results. First, the netback pricing rule for the price of domestic natural gas (based on a Houston benchmark price) leads to discontinuities in Pemex's revenue function. Second, having Pemex pay for the gas it uses and the gas it flares increases the value of the Lagrange multiplier associated with the gas processing constraint. Third, if the gas processing constraint is binding, having Pemex pay for the gas it uses and flares does not change the short run optimal solution for the optimization problem, so it will have no impact on short-run behavior. These results imply three clear policy recommendations. The first is that the arbitrage point be fixed by the amount of gas Pemex has the potential to supply in the absence of processing and gathering constraints. The second is that Pemex be charged for the gas it uses in production and the gas it flares. The third is that investment in gas processing and pipeline should be in a separate account from other Pemex investment. (orig.)

The present investigation was intended to evaluate the effectiveness of a course on health and the prevention of musculoskeletal injuries in future professional musicians, specifically designed for superior-grade students at the High Conservatory of Music of Salamanca, Spain. Students were taught how to evaluate the possible risks associated with the practice of their instruments. They were provided with information about the most frequent medical problems of musicians, warm-up habits, postural hygiene, effective prevention strategies, and different treatment options for these pathologies. The students were randomly divided into two groups: a control group (n=56) who did not take the course and was evaluated with a questionnaire at the beginning of the academic year and 1 year later, and an experimental group (n=90) who did take the course and was evaluated with three questionnaires (at the beginning of the course, 6 months later, and 12 months after the start of the course). While the students in the experimental group improved their body awareness by 91% and the frequency of their injuries decreased by 78%, there was no improvement in the students from the control group at the end of the experiment. The results of our study have demonstrated the effectiveness of this type of course and show that such courses should be included in the academic curriculum of superior conservatories.

Between 1978 and 1983, Petróleos Mexicanos (PEMEX) carried on an intense exploration program in the northern Gulf of California, the Sonora Desert and the southern part of the Mexicali Valley. This program was supported by a seismic reflection field operation. The collected seismic data was 2D, with travel time of 6 s recording, in 48 channels, and the source energy was: dynamite, vibroseis and air guns. Since 2007 to present time, the existing seismic data has been re-processing and ire-interpreting as part of a collaboration project between the PEMEX's Subdirección de Exploración (PEMEX) and CICESE. The study area is located along a large portion of the Pacific-North America plate boundary in the northern Gulf of California and the Southern part of the Salton Trough tectonic province (Mexicali Valley). We present the result of the processes reflection seismic lines. Many of the previous reported known faults were identify along with the first time described located within the study region. We identified regions with different degree of tectonic activity. In structural map it can see the location of many of these known active faults and their associated seismic activity, as well as other structures with no associated seismicity. Where some faults are mist placed they were deleted or relocated based on new information. We included historical seismicity for the region. We present six reflection lines that cross the aftershocks zone of the El Mayor-Cucapah earthquake of April 4, 2010 (Mw7.2). The epicenter of this earthquake and most of the aftershocks are located in a region where pervious to this earthquake no major earthquakes are been reported. A major result of this study is to demonstrate that there are many buried faults that increase the seismic hazard.

A methodology of risk operative analysis for damages, which are derived from theft of gasoline in Petroleos Mexicanos (Pemex) pipelines by third parts (clandestine pipes) is proposed. Originally, the problematic is studied from the global perspective of pipelines accidents happened in the world, in United States of America and in Mexico, and later it approaches specifically the environment that the industry of Pemex-Refinery pipelines. When the results are obtained, it is concluded that the factor of risk with more occurrence probability of pipelines, is due to damages for third parts, in first term, and followed by the damages originated by corrosion in second term. So a diagnostic is made of the physical vulnerability degree on the rights of way of Pemex. [Spanish] Se propone una metodologia de analisis de riesgo operativo en poliductos debido a danos por terceras partes (tomas clandestinas), originados del hurto de gasolinas en ductos de Petroleos Mexicanos (Pemex). La problematica se aborda desde una perspectiva global de accidentes en los ductos de Pemex-Refinacion. Del analisis y resultados obtenidos, se concluye que el factor de riesgo con mayor probabilidad de ocurrencia en poliductos, es debido a danos por terceras partes, en primer termino, seguido de los danos originados por corrosion.

Full Text Available During decades the policies towards oil and energy implemented in Mexico have resulted in the de pletion of reserves, the explosion of debt of Pemex (90 per cent of its capital, and the dramatic petrolization of the total fiscal revenue. High prices, the war on terror and political instability in oil rich regions have reinforced usA policy of "energy security" and the interest in the creation of the Common Market on Energy, as the way to strengthen the TLCAN. To respond to these two forces Mexico will have to reform its traditional oil policy. All possible options: to reduce the fiscal burden upon Pemex or to open to private investments the exploration of oil have excruciating political costs, which no government has shown the will to confront.

Foreign firms to get equal opportunity in Mexican selloff plans

Petroleos Mexicanos (Pemex) has not finalized details of its long-awaited petrochemical privatization program. However, the state oil group has made it clear the selloff schedule, due to begin during the next two months, will give equal investment opportunity to foreign firms, dashing the hopes of Mexican groups that they would be given first right of refusal in the privatization program. Meanwhile, Pemex has agreed with Shell Oil on a previously announced refining joint venture involving Shell's 225,000-bbl/day refinery at Deer Park, TX. Under the plan, Pemex will purchase a 50% stake in the refinery and join Shell in a $1-billion upgrade with would enable it to handle more Mexican crude. Sources believe that Shell and other US oil groups are interested in acquiring assets from Pemex Petroquimica

Market study on the oil and petroleum industry in Mexico

International Nuclear Information System (INIS)

1991-01-01

The historical background of the Mexican petroleum industry is outlined and an overview is presented of the state of the Mexican economic environment. The Mexican market for oil and gas field equipment is estimated, with a focus on the oil monopoly PEMEX. The total imports of oil and gas field equipment are estimated to increase to US$280.4 million in 1992, and the most important foreign suppliers are led by the USA, which has a 72% share. Canadian exports of oil and gas field equipment have remained fairly stable during the last few years at $2.4-2.7 million. In general, prospects for Canadian suppliers to the Mexican market are best in the area of technologically sophisticated equipment. An end-user profile of PEMEX is presented, noting that it is the largest enterprise in Latin America and had $14.2 billion in sales in 1989. Equipment imported by PEMEX includes seamless steel pipe, drilling tools, gate and control valves, electric motors, processing and control equipment, steam and gas turbines, and telecommunications equipment. PEMEX activities in 1989 are reviewed, including those in the petrochemical sector, and projected activities are described. Major efforts planned by PEMEX include expansion of petrochemical production. Access to the Mexican market is discussed in terms of PEMEX purchasing policy, payment system, import requirements, the need for using a supplier agent, and use of the metric system and other standards. 6 figs., 2 tabs

State of Tabasco: A Mexican petroleum district. Ein mexikanischer Erdoelstaat: Tabasco

Energy Technology Data Exchange (ETDEWEB)

Jacobsen, M.

1986-01-01

The Tabasco region is located in the southeast of Mexico. Before the petroleum boom in the mid seventies, agriculture was its dominant source of revenue. Farmers were generally earning their living by the small- and medium-scale production of basic foods, the cultivation and export of tropical fruits (cyclical phases of banana and cocoa cultivation) as well as by cattle-breeding. The discovery and exploration of extensive petroleum deposits placed in the hands of the national oil company PEMEX resulted in drastic and complex changes of the country's socio-economic structures. The publication reveals the gloomy situation of the Tabasco region. Within a few years only the PEMEX activities have 'covered' Tabasco with an 'oil slick' which has not - as might be assumed - contributed to a general prosperity but to the destruction of the environment, the speculation on real estate, extensive corruption and, which is more, to an always increasing proletarization and pauperization of that part of the population which is not directly connected to the pipeline.

Applying a Virtual Economy Model in Mexico's Oil Sector

Baker, G.

1994-01-01

The state of Mexico's oil industry, including the accomplishments of Pemex, Mexico's national oil company, was discussed, with particular reference to the progress made in the period of 1988-1994, and the outlook for innovations in the post-Salinas era. The concept of an evolutionary trend from a command economy (State as sole producer), towards market (State as regulator) or mixed economies (State as business partner) in developing countries, was introduced, placing Pemex within this evolutionary model as moving away from centralized control of oil production and distribution, while achieving international competitiveness. The concept of ''virtual market economy'' was also discussed. This model contains the legal basis of a command economy, while instituting modernization programs in order to stimulate market-economic conditions. This type of economy was considered particularly useful in this instance, sine it would allow Pemex units to operate within international performance and price benchmarks while maintaining state monopoly. Specific details of how Pemex could transform itself to a virtual market economy were outlined. It was recommended that Pemex experiment with the virtual mixed economy model; in essence, making the state a co-producer, co-transporter, and co-distributor of hydrocarbons. The effects of such a move would be to bring non-debt funding to oil and gas production, transmission, and associated industrial activities

The granometric and morphometric parameters of these cassiterites have been compared with those shown by the cassiterite crystal ocurrying in the Golpejas granite. The comparison between the two groups of data allow us to conclude that the anomaly observed in the Regato de los Lentiscos has been originated by the disperssion of the cassiterite from the primary deposit of Golpejas. On the contrary. the anomaly ocuring in the alluviums to the south of Tirados de la Vega shows a different origin, and is coming from stanniferous veins. The factor analysis corroborates the differentiation mentionated aboye. and indicates a migration capacite of about 3 Kms. from the stanniferous deposits of Golpejas for the alluvial cassiterite.En el sector Tirados de la Vega-Golpejas han sido detectadas dos anomalías de casiterita en los aluviones del Regato de los Lentiscos y en otros existentes al sur de Tirados de la Vega. El estudio granométrico y morfométrico de éstas casiteritas. contrastado con el de la casiterita procedente del granito de Golpejas. permite asegurar que la anomalía del Regato de los Lentiscos se debe a la dispersión de la casiterita de aquel granito. mientras que la de Tirados de la Vega procede de filones estanníferos. La aplicación del análisis factoral corrobora este hecho y permite diferenciar las casiteritas que proceden de rocas graníticas de aquellas que vienen de filones estanníferos. Según esto se puede indicar que la capacidad de migración de la casiterita desde el yacimiento estannífero de Golpejas es de unos 3 Kms.

Mexico: World Oil Report 1991

Maciej, H.

1991-01-01

This paper reports that state oil company Pemex appears to be in the middle of a mini-renaissance. Senior management proudly points to several areas of improvement, including a major reduction in the power of petroleum labor unions; a structural reorganization of the company into profit and cost centers; a significant trimming of foreign and domestic debt; and the growing readmittance of foreign investment and technology. Effects of these policy successes already are quantifiable and impressive. Restricting the unions' power has allowed Pemex to break the old habit of employing too many people and paying them too much. Indeed, the workforce has shrunk 30% to just below 150,000. Under the guidance of Finance Director Ernesto Marcos, Pemex has whittled its foreign debt to $5.6 billion from a 1982 high of $20 billion. Furthermore, the extra income provided by higher oil prices during the Persian Gulf war allowed Pemex in December to completely pay off its domestic debt, which has been nearly 2.5 trillion pesos (about $850 million) in the first quarter of 1990

Full Text Available

Halfway through the 16th century in Spain the reading and interpretation of the Bible based on its original languages involved a very real danger for humanists who were seeking a better understanding of the Scriptures. The exclusive authority of the Latin Vulgate version declared by the Council of Trent in 1546 hindered the intellectual work of many Biblicists and Theologians, who were subjected to tight ideological control. In this context it must be considered the case of the Hebraist and scholar from the University of Salamanca, Martín Martínez de Cantalapiedra (1518-1579, who was prosecuted by the Inquisition of Valladolid in 1572 along with his colleagues Fray Luis de León and Gaspar de Grajal. All of them were accused of deviating from the genuine sense of the Vulgate in their more literal interpretations of the Masoretic text. The purpose of this article is to provide new evidence for the intellectual biography of Master Martínez de Cantalapiedra as well a to analyze the hermeneutical principles exposed during his inquisitorial in which he defended the Hebrew knowledge as an essential means of interpreting the Old Testament.

and bi-directional currents. Unique features within these two facies such as microdeltas and plane parallel lamination indicate complex micro-environments and flow patterns. Fossil plant remains lie within lateral accretion sets or siltstone facies both above and below the trough cross-bedded sandstone facies. At the top of the Salamanca we reach facies 6 and 7 which transition from sandstone to black mudstone of the Banco Negro. Mammal fossils found in the Banco Negro identify it as a non-marine continental facies. The Late Paleocene Rio Chico formation that overlies the Banco Negro is identified as a continental fluvial formation indicating that facies 6 represents emptying of the estuary and a longstanding regional transition from a marine to a continental environment. To understand the origin of the tidal flows, a paleogeographic model of the Late Danian Patagonian shelf was constructed from facies distributions within the Salamanca Fm. A 2D hydrodynamic model driven by predicted tides in the paleo-Atlantic produces a tidal range of approximately 2m and strong ebb and flood tides throughout the central estuary. These observations are consistent with our interpretation of a meso-tidal estuarine environment as the paleo-flora accumulation site.

Das genannte Gebiet liegt an der kolumbianischen Atlantikküste zwischen Barranquilla und Ciénaga und wird im Norden von der karibischen See und im Süden von der Ciénaga Grande de Santa Marta begrenzt. Die mittlere Jahrestemperatur beträgt 28° C. Die Trockenzeit dauert fünf Monate, die jährliche Niederschlagsmenge liegt wahrscheinlich bei 700 mm. Der Boden besteht überall aus Sand.  Weite Teile der Insel, vor allem im Westen, sind mit Mangrove bedeckt. Im Osten, wo die Untersuchungen durchgeführt wurden, breitet sich auf höher gelegenen Stellen ein 5-7 m hohes Gebüsch aus Dornsträuchern und Kakteen aus, In Gebieten, die sich wenig über Meeresniveau erheben, ist der Boden versalzen und entweder vegetationslos oder mit Halophyten, vor allem Batis maritima und Sesuvium portulacastrum, bedeckt. Die Bodenversalzung wird hauptsächlich durch bis an die Oberfläche aufsteigendes und dort verdunstendes salzhaltiges Grundwasser verursacht.  Während der Trockenzeit lagert sich auf den unbewachsenen Flächen eine Salzkruste ab, die in der Regenzeit durch Niederschläge ausgewaschen wird. Der Salzgehalt der mit Halophyten bestandenen Gebiete kann in der Trockenzeit über den der unbewachsenen Stellen ansteigen, was möglicherweise auf die Wasseraufnahme durch die Pflanzen und den dadurch verstärkten Wasserentzug zurückzuführen ist.  Soweit das Grundwasser dicht unter der Bodenoberfläche steht, ist ein das ganze Jahr über hoher Bodenwassergehalt vorhanden. Je mehr das Niveau ansteigt, desto geringer wird er, Am Ende der Trockenzeit kann die Wasserversorgung an mit Pflanzen bestandenen Stellen stärker beansprucht sein als an vegetationslosen. Jedoch hält in der Regenzeit der bewachsenen Boden die Niederschläge besser fest als der unbewachsene. Der Trockenbusch breitet sich nur an solchen Stellen aus, an denen das salzhaltige

In order to observe the effect of the concentrations, several satellite images taken before and after the concentration process have been compared. The creation of 8 metre wide tracks by cutting trees and flattening the land has caused the disappearance of many hectares of forests which were either mature or in a process of regeneration. The fencing of the new parcels of land is causing the fragmentation and insularity of the land, resulting in a major impact on the metapoblational dynamics of the rich invertebrate land fauna.

Abstract Introduction: The spinal tumors are rare neoplasms, they can be primary or metastatic; in the literature they are divided in extradural and intradural, extramedullary and intramedullary, from which extradural tumors are the most frequent and are usually metastatic, the intramedullary are generally gliomas. From the primary tumors up to 78% are benign and 22% malign, the histological stripe and the involvement to the spinal compartments are of great importance for the results and the treatment which is mainly surgical, individualized and meticulously planned with the support of technological resources such as the electrophysiological monitoring during the surgery. Methods and Materials: Observational study with a range of patients from March 1999- March 2016 to whom surgical resection of the spinal tumor was performed and reported on the Electronic Files of the South Central Hospital of High Specialty PEMEX. A Statistical analysis is made with the SPSS Statistic of disease of the Institution program. Results: 23 patients with spinal tumor surgical resection were found. The median age was 53 ± 10 years. The most common clinical manifestation was radiculopathy (65%). The Karnofsky scale was used for initial evaluation where a 43% of patients had a 90 score at the moment of the diagnosis, while 65% had an ECOG 1. The most frequent tumor was the Spinal Shwannoma (39%), followed in prevalence by the Condroid Cordoma (17%), where the intradural extramedullary location was the most prevalent (78%). The medium rate of survival after the surgical procedure was from 11 months. Conclusions: Our cases and the international statistics coincide. Radiculopathy as high prevalence initial manifestation conceals us to dismiss in the sixth decade of life any possibility for spinal tumor presentation. Most of spinal tumor patients do not have any clinical deterioration in their basal state, which indicates that performing a successful surgical procedure and the right

Abstract Introduction: The peripheral sheath tumors are part of a large group of neoplasms that range from biologically benign with minimal disorders in life quality to highly malign with life quality deterioration and high mortality. There are subtypes with high prevalence like Schwannomas and some much rarer like the intracranial peripheral nerve sheath tumor which happen to have very bad prognosis. The aim of this study is to describe the epidemiologic and clinical characteristics of patients with peripheral nerve sheat tumors in a hospital of high specialty. Method and materials: Observational study with patients from March 1999 to March 2016 with confirmed diagnosis of peripheral nerve sheath tumor in the electronic files of the South Central Hospital of High Specialty PEMEX. A statistical analysis is made through the SPSS Statistics of the disease in this Institution program. Results: There were 84 patients with the diagnosis of peripheral nerve sheath tumor with a median age of 48.04 years, 65.5% were males, the most common histological type found was the Schwannoma with a 72.6%, followed by senescent Schwannoma 13.1%, neurofibroma 8.3%, and malign peripheral nerve sheath tumor 2.4%. The most frequent location was at the site of cranial nerves, followed by cervical level 27.4%, lumbar 16.7% and thoracic 9.5%. The most common initial symptom was pain in 23.8% of the patients, and the time of the onset of symptoms to the diagnosis was 31.6 months. From the total of patients 8.3% had neurofibromatosis type 1, 6.0% neurofibromatosis type 2. Conclusions: We realized in our series of reported cases that the frequency is similar to those reported in worldwide population; nevertheless the time between the onset of symptoms and the diagnosis is much higher in our cases as well as the population of patients with neurofibromatosis. This study justifies the need of attention quality improvement and the knowledge of this information the medical doctor of first

In this work, are presented the technical and economic elements of the international experience for the installation of IGCC power plants in the petroleum refinement and the lessons for Mexico in the installation of this technology in PEMEX Refinacion are analyzed. The construction of IGCC power plants in the petroleum refinement has grown 14.3 % at worldwide level as of 1996, in which there was already an installed capacity of 160 MW. At the end of 2003 an installed capacity of 2,500 MW was reached. The growth in the installation of IGCC power plants fundamentally appears in Europe, being Italy and Spain leader countries in the construction of this technology in the petroleum refinement. However, countries like Holland, Japan, Singapore and the United States count on IGCC power plants for electricity and hydrogen generation, which take advantage of low value fuels such as vacuum tower residues, petroleum coke, asphalt, liquid fuels, among others. In Mexico, the installation IGCC power plants in the petroleum refinement is null, nevertheless Petroleos Mexicanos counts with the approval of the government for the installation of cogeneration power plants in its facilities. This approval would allow PEMEX to carry out projects for the installation IGCC power plants, specifically in PEMEX Refinacion, for the generation of electricity and hydrogen from the advantage of heavy residues of low economic value. The opportunity that the installation IGCC power plants in the petroleum refinement offers is directed towards the commercialization of the electricity and hydrogen, which would impel PEMEX Refinacion to enter the competition of the electrical market in Mexico.

Mexico's critical choices

International Nuclear Information System (INIS)

Marcos, E.

1990-01-01

In Mexico, the 1982 fall in international oil prices shook the national conscience and pushed the Mexican people in search of a new national image and toward the choices they must make to attain that image. But, according to the author of this paper, the country as a whole has already made critical choices for overall strategy and there are reasons for optimism. In the current economic environment of growing domestic demand and enhanced international competitiveness, the author sees PEMEX (the Mexican national oil company) facing not only the challenge of responding to the rapid changes taking place in the Mexican economy, but also making a significant contribution toward the solid and stable growth of the country. The relevant question is how PEMEX will live up to these expectations. This paper describes several steps PEMEX has taken already or is preparing to take in order to meet this challenge, including: investment in the domestic petrochemical industry; entry into the Eurobond market; development of new methods of project financing

2017-01-01

We present a study of some organizational properties of the oil transport network of the Mexican oil company (PEMEX) in a region of the State of Tabasco. Particularly, the generalized centrality and the distribution of connectivities are calculated in order to evaluate some aspects of the structure of the network. We find that the connectivities (k) are characterized by a degree distribution which follows a power-law function of the form, P(k)~k -λ, with λ = 2.6. Moreover, our procedure permits to evalute the importance of lines (ducts) and nodes, which can be wells, production headers, separation batteries and petrochemical complexes.

2014-04-01

Full Text Available Acquisition footprint, one of the major problems that PEMEX faces in seismic imaging, is noise highly correlated to the geometric array of sources and receivers used for onshore and offshore seismic acquisitions. It prevails in spite of measures taken during acquisition and data processing. This pattern, throughout the image, is easily confused with geological features and misguides seismic attribute computation. In this work, we use seismic data from PEMEX Exploración y Producción to show the conditioning process for removing random and coherent noise using linear filters. Geometric attributes used in a workflow were computed for obtaining an acquisition footprint noise model and adaptively subtract it from the seismic data.

Piedra Pajarilla: A candidate for nomination as Global Heritage Stone Resource from Spain

Science.gov (United States)

Pereira, Dolores; Gimeno, Ana; del Barrio, Santiago

2013-04-01

Piedra Pajarilla is a tourmaline bearing leucogranite outcropping at Martinamor, near Salamanca, Spain. It is part of the Hercynian granitic chain in the Spanish Central System. The stone received the local name "Piedra Pajarilla", meaning "Little Bird Stone" due to the shape of the many tourmaline aggregates that are the main visual feature of the rock. This local name has been extrapolated to every granitic stone used in the area, even if they differ significantly in mineralogy, and as recently tested in physical and mechanical properties as well. Here we present the nomination of Piedra Pajarilla as a suitable "Global Heritage Stone Resource". This stone ideally fits the newly proposed designation as it has been used since Roman times in Salamanca (Spain) and since the Middle Ages in the construction of major historic buildings, including both the Old and New Cathedrals, and many additional churches, castles and walls in the Salamanca area. Salamancás historic city core has been granted UNESCO World Heritage status in 1988, and all associated buildings, monuments and pedestrian streets are constructed from original materials. One of utilised materials, Piedra Pajarilla, was quarried for centuries from the immediate area. It was also the preferred building stone of many internationally renowned architects of Spanish origin during the 18th and 19th centuries especially involved in reconstruction following the Lisbon earthquake. Although the associated quarries are no longer active, the Piedra Pajarilla quarry sites remain relatively undisturbed and accessible. A renewal of quarrying is consequently feasible if additional stone supplies are required for heritage restoration. Thus there is also a need to preserve these historic quarries in anticipation of such work. The importance of Salamanca as emblematic heritage makes the historic stone quarries worthwhile to preserve as well. At the same time, Piedra Pajarilla can be considered as the first of several natural

Population, petroleum, and politics: Mexico at the crossroads. Part 2. The potentials and problems of Mexican oil resources.

Gallagher, C F

The 2 most important factors which will influence Mexico's future economic development are the country's overpopulation problem and the manner in which the country's oil reserves are exploited. This document describes the historical development of Mexico's oil industry and the current struggle of the government to ensure that the oil resources contribute toward the sound economic development of the country. The government expropriated foreign oil companies in 1938 and today most of the oil operations in Mexico are conducted by the state controlled Pemex Company. In recent years extensive oil reserves were discovered in Mexico and the country is now in the position of having large oil reserves at a time when oil prices are increasing. Known crude oil reserves are estimated at 31 billion barrels; however, an unconfirmed report by Pemex in 1980 placed the known reserves at 50 billion barrels. In the past the management of Pemex was corrupt and inefficient and many top positions in the company were filled by retired politicians. The recent appointment of Jose Andres de Oteyza as Chairman of the Board and of Jorge Diaz Serrano as the Director-General should greatly improve Pemex operations. In developing the country's oil industry the government wants 1) to keep production low enough to offset inflation and to preserve the resource but 2) to produce enough oil so that the country has sufficient funds for investment and for operating needed social programs. The government may not be able to keep oil production down to acceptable levels. It may be forced to increase oil exports to compensate for its growing reliance on imported food and other imported products. In recent years Mexico's industrial productivity and its agricultural production declined. The government wants to avoid being placed in the position where it will be forced to trade large quantities of oil for needed food. The current government is promoting investment in agriculture and industrial development in

Oil's role in free trade agreement crux of Mexico's petroleum sector dilemma

Mexico's president Salinas' efforts at privatization have not yet touched Mexico's most valuable industry, oil. That remains under control of state owned Petroleos Mexicanos. Pemex and Mexico's huge oil union have come under increasing criticism for alleged abuses of power. In addition, controversy rages as to the true extent of Mexican oil resources and whether Pemex has the wherewithal to meet domestic demand and sustain oil exports. Critics also contend opening Mexico's oil sector to foreign participation would introduce new efficiencies and cost cutting measures in the cash strapped state oil industry. This paper reports that at the center of the controversy is the proposed Free Trade Agreement among Mexico, the U.S., and Canada, pushed strongly by Salinas. Oil's role in the FTA may prove the pact's main sticking point

This volume contains most of the presentations delivered at this international workshop. This meeting was the second in the series following the previous I Encuentro Ibérico de Compstar, held at the University of Coimbra, Portugal in 2010. The main purpose of this meeting was to strengthen the scientific collaboration between the participants of the Iberian and the rest of the southern European branches of the European Nuclear Astrophysics network, formerly, COMPSTAR. This ESF (European Science Foundation) supported network has been crucial in helping to make a broader audience for the the most interesting and relevant research lines being developed currently in Nuclear Astrophysics, especially related to the physics of neutron stars. It is indeed important to emphasize the need for a collaborative approach to the rest of the scientific communities so that we can reach possible new members in this interdisciplinary area and as outreach for the general public. The program of the meeting was tailored to theoretical descriptions of the physics of neutron stars although some input from experimental observers and other condensed matter and optics areas of interest was also included. The main scientific topics included: Magnetic fields in compact stars Nuclear structure and in-medium effects in nuclear interaction Equation of state: from nuclear matter to quarks Importance of crust in the evolution of neutron stars Computational simulations of collapsing dense objects Observational phenomenology In particular, leading

A North Sea approach for Mexico?; El marco Mar del Norte para Mexico?

The probable existence of oil and gas deposits in the border territory between Mexico and the United States has waked up an enormous restlessness given the lack of agreements and stipulations on the handling of such deposits; cases like this one have occurred in other parts of the globe and it is indeed the intention of this article to show how the agreement decided on the North Sea can be applied in the case of Mexico. The bilateral characteristics of this agreement conformed by incentives and openings to the market, require the cooperation of different offices and governmental sectors from the federal government to make a series of possible stipulations that regulate the treaty and allow different oil companies a substantial interaction that profits the owners on both sides of the border. In Mexico the responsibility to put in action projects of this type corresponds to the legislative power in complicity with the secretariats of Foreign Affairs and Work. The present action models and the monopoly of Petroleos Mexicanos (PEMEX) in Mexico have only managed to suspend the development of the country in this sector and to maintain the oil industry development in a mediocre and deteriorated level. The benefits of such an adjustment would extend beyond obtaining a bilateral development for the involved countries; nevertheless we remember that the government of the United States is not to the compass of the governments pro-unification of borders. In order to begin the unification of the border regions, Mexico must document the location of border wells, nevertheless even though any agreement could be reached, years would have to pass before PEMEX develops the appropriate technology to operate its part of the deposits.

Exploring the KT source crater: Progress and future prospects

Science.gov (United States)

Sharpton, Virgil L.

It has been 15 years since an iridium-enriched clay layer at the Cretaceous-Tertiary (KT) boundary was discovered, providing the first hard evidence linking the most recent mass extinction event to a comet or asteroid strike [Alvarez et al., 1980]. Now it is widely accepted that the site of this collision is on the Yucatan platform, centered near Progreso, Mexico. The 200-300-km-wide crater lies buried beneath 300-1000 m of limestone laid down in the intervening 65 million years, and few clues of its presence remain at the surface, save an arcuate arrangement of water-filled sinkholes centered approximately on the structure (Figure 1). Yet prominent circular anomalies in gravity and magnetic anomaly maps gained the interest of Petroleos Mexicanos (Pemex), and in the early 1950s they began an exploration campaign that included deep drilling to recover samples of the subsurface rocks. The buried feature became known as the Chicxulub structure. Pemex drilling continued throughout the early 1970s and by that time, three wells near the center had recovered silicate rocks with igneous textures, initially mistaken for volcanic rocks. Other wells, located between 130 km and 210 km from ground zero recovered breccia deposits hundreds of meters thick that showed evidence of catastropic or explosive conditions. By 1980, Antonio Camargo, a geophysicist at Pemex, felt the evidence pointed to impact, although a volcanic origin for the Chicxulub structure could not be ruled out.

Smart Waste Collection System with Low Consumption LoRaWAN Nodes and Route Optimization

Full Text Available New solutions for managing waste have emerged due to the rise of Smart Cities and the Internet of Things. These solutions can also be applied in rural environments, but they require the deployment of a low cost and low consumption sensor network which can be used by different applications. Wireless technologies such as LoRa and low consumption microcontrollers, such as the SAM L21 family make the implementation and deployment of this kind of sensor network possible. This paper introduces a waste monitoring and management platform used in rural environments. A prototype of a low consumption wireless node is developed to obtain measurements of the weight, filling volume and temperature of a waste container. This monitoring allows the progressive filling data of every town container to be gathered and analysed as well as creating alerts in case of incidence. The platform features a module for optimising waste collection routes. This module dynamically generates routes from data obtained through the deployed nodes to save energy, time and consequently, costs. It also features a mobile application for the collection fleet which guides every driver through the best route—previously calculated for each journey. This paper presents a case study performed in the region of Salamanca to evaluate the efficiency and the viability of the system’s implementation. Data used for this case study come from open data sources, the report of the Castilla y León waste management plan and data from public tender procedures in the region of Salamanca. The results of the case study show a developed node with a great lifetime of operation, a large coverage with small deployment of antennas in the region, and a route optimization system which uses weight and volume measured by the node, and provides savings in cost, time and workforce compared to a static collection route approach.

Can Latin American Oil Companies Free Themselves from the Legacy of Nationalization? (Can Latin American Oil and Gas Companies Break Free of Their Nationalized Past?) - CERI Studies No. 183

International Nuclear Information System (INIS)

Rousseau, Isabelle

2012-01-01

Latin America's national oil companies, created at various times during the twentieth century, have each evolved in a different way. The two main companies - Petroleos de Mexico (Pemex) and Petroleos de Venezuela (PDVSA) - provide excellent illustrations of the rich diversity of organizational and industrial development. Many factors - such as the importance of earth quakes - explain the diversity. Nevertheless, the role of governments during the period of nationalizations is key. It was then that the relationships between the owners of natural resources, public operators, regulators, the finance ministries, and international operators were defined. This process shaped the companies' institutional structures (path dependency) and set the parameters for future entrepreneurial dynamism. The path by which each of these enterprises developed continues to affect their culture as evidenced by the recent reforms which attempted to restructure Pemex and PDVSA. (author)

Abstract Introduction: Primary lymphomas of the central nervous system are a type of Non Hodgkin Lymphoma with high morbidity and mortality. They are frequently associated with HIV infection, nevertheless the prevalence in non HIV patients has been tripled recently without any justified cause. In occasions it is difficult to identify the difference between primary and secondary origin in the central nervous system, this is crucial since the prognosis also changes. Method and Materials: Observational study with a range of patients from March 1999- March 2016 with reported diagnosis of Non Hodgkin Lymphoma with Central Nervous System involvement inside the electronic files of the South Central Hospital of High Specialty PEMEX. A statistical analysis is made through the SPSS Statistics of the Disease in this Institution program. Results: There were a total of 20 patients found with the diagnosis of Non Hodgkin Lymphoma with Central Nervous System involvement with a media of 57.7 ± 16 years of age, 60% males. 45% were classified as primary; multiple variables were analyzed such as the histological subtype from which the most common was Giant B cell types in a 40%. Within the symptoms the most common was headheach and pyramidal syndrome with 25%. At the time of diagnosis we found that with most prevalence ECOG of the population was of 1 reported case of 55 % of patients, nevertheless the survival rate after diagnosis had a global media of 40.3 ± 21 months, being of 56 months in secondary lymphoma and of 16 months in primary lymphoma, there were no significant statistical differences in both groups. Conclusions: The clinical and epidemiological characteristics in both groups were similar to the ones reported in the literature, nonetheless compared with the time of diagnosis based on the ECOG the overall rate of survival in both groups is low, which brings a great challenge for medical and surgical management. It is important to denote that the clinical

The discharge of nutrients, phytoplankton and pathogenic bacteria through ballast water may threaten the Cayo Arcas reef system. To assess this threat, the quality of ballast water and presence of coral reef pathogenic bacteria in 30 oil tankers loaded at the PEMEX Cayo Arcas crude oil terminal were determined. The water transported in the ships originated from coastal, oceanic or riverine regions. Statistical associations among quality parameters and bacteria were tested using redundancy analysis (RDA). In contrast with coastal or oceanic water, the riverine water had high concentrations of coliforms, including Vibrio cholerae 01 and, Serratia marcescens and Sphingomona spp., which are frequently associated with "white pox" and "white plague type II" coral diseases. There were also high nutrient concentrations and low water quality index values (WQI and TRIX). The presence of V. cholerae 01 highlights the need for testing ballast water coming from endemic regions into Mexican ports.

From the end of a revolution to the beginning of an evolution: An interpretive investigation on the Mexican oil culture

Science.gov (United States)

Marquez-Perez, Pedro Gabriel

2001-07-01

This dissertation is an interpretative investigation on the Mexican petroleum industry. It studies the social arrangement that allowed the development of Mexico's most important State-Owned Enterprise Petroleos Mexicanos and the current pressures to transform it. The need to modify its operations in Mexico is an issue of enormous significance for the current reforms undertaken by the Neo-liberal project initiated during the mid 1980's. It represents the abandonment of the development strategy that characterized the "Regime of the Revolution" and the establishment of a market-oriented economy in line with the development strategy selected by the President Fox for the period 2000--2006. Through an approximation of Habermas' ideal 'Public Sphere' this dissertation reveals relevant information about PEMEX's historical and present contexts, the basic elements that make up the Mexican petroleum culture, its major interest groups, their mutual perspectives and understandings, their interpretation of the present situation and their opinion as to the way PEMEX should be modified. The investigation into the ideas, beliefs and customs that justified PEMEX's hegemony over Mexico's petroleum resources followed the conceptual model provided by the Critical Theory Paradigm and an adaptation of a methodological approach previously employed for qualitative Critical Theory research. Throughout an ethnographic analysis of twenty-six representatives of PEMEX's major interest groups through in-depth, semi-structured interviews based on a combination of an interpretative research design and a case-study research method, the beliefs, ideals, mutual perceptions and future plans of these stakeholders were identified. This study advances the understanding of the symbols, beliefs and ideas that have framed Mexican petroleum culture, as well as describes how these beliefs and ideas have changed over time. Through an 'ethnography of rhetoric,' this project facilitated the absorption and

Through a retrospective analysis of Mexico's oil history, this work examines the privatization processes that occurred in the petrochemical sector, from the abolishment of the government's monopoly, Petroleos Mexicanos (PEMEX) during the 1980s, until the restructuring and open liberalization in the early 1990s, focusing on the areas incorporated to production processes, particularly along the Gulf coast. As a result of the industrial policies and regional development strategies promoted by the government from the sixties, oriented towards strengthening production in areas with the highest potential, attractive business investment areas were developed. These included southern Tamaulipas, a strategic region where a number of industrial factors facilitated access to raw materials at competitive prices, as well as their processing and distribution to local and international markets, all of these within a single location. The strategic nature of the petrochemical location and production have made southern Tamaulipas a key factor for the territorial shaping and industrial development linked to the behavior of transnational companies that, seeking comparative advantages, have relocated parts of their production capacity in this region

On the 23th of May 2007 at 14:09 local time (19:09 UT) an insolated earthquake of local magnitude 5.2 occurred offshore northern Veracruz in the Gulf of Mexico. The seismic focus was located using local and regional data at 20.11° N, 97.38° W and 7.8 km depth at 175 km distance from Tuxpan a city of 134,394 inhabitants. The earthquake was widely felt along the costal states of southern Tamaulipas and Veracruz in which several schools and public buildings were evacuated. Neither Laguna Verde nuclear plant, located approximately 245 km from the epicenter, nor PEMEX petroleum company reported damage. First-motion data indicates that the rupture occurred as strike slip faulting along two possible planes, one oriented roughly north-south and the other east-west. In the present paper a global analysis of the earthquake is made to elucidate its origin and possible correlation with known geotectonic features of the region.

The results of the Mexican election and the implications it may have on foreign investment

The general effects of the recent Mexican election on that country's socio-economic development are discussed. Future directions of the new government include a trend toward greater deregulation, more privatization, and a greater importance of social welfare policies. The Mexican climate for new investment appears positive; the first half of 1994 saw $8 billion of foreign investment in Mexico. Canadian investment in Mexico dates from the 1850s and Mexico is now Canada's largest economic and trading partner in Latin America. Canada-Mexico trade is expected to rise to over $8 billion/y by 2000. To assist in this relationship, a Canadian Business Centre was opened in Mexico City in 1994 and programs are in place to aid potential Canadian exporters. The implications of the above developments for the oil and gas industry are examined. The Mexican state oil monopoly PEMEX is concentrating on core activities (extraction and refining of oil) and has sold almost all of its secondary petrochemical business. Private contractors can now obtain drilling contracts. PEMEX plans to invest ca $23 billion between now and 2000 and it is likely that at least some of this investment will come via partnerships between private firms and government. This is especially possible in the natural gas sector, where supply and demand are essentially in balance. Gas production will likely increase 60-80% by 2001 and Canadian companies are well suited to help bring this about. Some Canadian firms such as Novacorp and Associated Pipeline Services are already doing business with PEMEX or participating in joint ventures with Mexican firms. Suggestions are offered for doing business in Mexico

From the data of chemical composition of the water, the chemical equilibrium at a given temperature can be modeled for, later, obtain the saturation indexes of characteristic minerals with the intention of knowing or predict which phases can form the deposits. The Gerencia de Productividad de Pozos (GPP) of the Subdivision of Technology and Professional Development (STDP) of PEMEX, has among its objectives to promote studies tending to solve problematic that affect the wells productivity, reason why it showed interest in making a study of chemical modeling of formation waters of the Active Luna, in order to know the saturation state of the main mineral phases. This way a joint project was executed in 1997 among the GPP, the Active of Production Luna of PEMEX and the Gerencia de Geotermia of the IIE. The objectives of the project were: (a) sampling and physicochemical characterization of waters pertaining to oil wells of the Actives of Production Luna, and (b) modeling of the chemical equilibrium at well head and deposit conditions to obtain saturation indexes of characteristic minerals of hydrothermal systems, in order to predict the mineral phases that can be found in superficial and deep incrustations. [Spanish] A partir de los datos de composicion quimica del agua, pude modelarse el equilibrio quimico a una temperatura dada para, posteriormente, obtener los indices de saturacion de los minerales caracteristicos con el objeto de conocer o predecir cuales fases pueden formar los depositos. La Gerencia de Productividad de Pozos (GPP) de la Subdireccion de Tecnologia y Desarrollo Profesional (STDP) de Pemex, tiene entre sus objetivos promover estudios tendientes a resolver problematicas que impactan la productividad de los pozos, por lo que mostro interes en realizar un estudio de modelacion quimica de las aguas de formacion del Activo Luna, con el proposito de conocer el estado de saturacion de las principales fases minerales. De esta forma se realizo un proyecto

Early Cretaceous (∼129 Ma) silicic rocks crop out in SE Uruguay between the Laguna Merin and Santa Lucia basins in the Lascano, Sierra Sao Miguel, Salamanca and Minas areas. They are mostly rhyolites with minor quartz-trachytes and are nearly contemporaneous with the Parana-Etendeka igneous province and with the first stages of South Atlantic Ocean opening. A strong geochemical variability (particularly evident from Rb/Nb, Nb/Y trace element ratios) and a wide range of Sr-Nd isotopic ratios ( 143 Nd/ 144 Nd (129) =0.51178-0.51209; 87 Sr/ 86 Sr (129) =0.70840-0.72417) characterize these rocks. Geochemistry allows to distinguish two compositional groups, corresponding to the north-eastern (Lascano and Sierra Sao Miguel, emplaced on the Neo-Proterozoic southern sector of the Dom Feliciano mobile belt) and south-eastern localities (Salamanca, Minas, emplaced on the much older (Archean) Nico Perez terrane or on the boundary between the Dom Feliciano and Nico Perez terranes). These compositional differences between the two groups are explained by variable mantle source and crust contributions. The origin of the silicic magmas is best explained by complex processes involving assimilation and fractional crystallization and mixing of a basaltic magma with upper crustal lithologies, for Lascano and Sierra Sao Miguel rhyolites. In the Salamanca and Minas rocks genesis, a stronger contribution from lower crust is indicated. (author)

The Venta de Carpio Terminal is located in the Northern part of the old Texcoco Lake, State of Mexico, in highly compressible soil. In it, it is received, regulated, measured and distributed natural gas, LP gas and PEMEX Refinacion products that are supplied to distribution terminals of and consumption centers located in the central area of the country, that encompasses the states of Puebla, Tlaxcala, Mexico, Hidalgo, Queretaro and a small part of the Federal District. The construction of the Venta de Carpio station dates from 1960; since then, it has presented important regional settlements, mainly due to the water extraction of the subsoil, that have imposed deformations to the piping systems connected to the surface facilities that have been piloted in the terminal. Equally, other surface piping systems and facilities present deformations by differential settlement between their supports. [Spanish] La Terminal Venta de Carpio se ubica en la parte norte del antiguo Lago de Texcoco, Estado de Mexico, en terreno altamente compresible.

La construccion de la estacion Venta de Carpio data de 1960; desde entonces, se han presentado asentamientos regionales importantes debidos, principalmente a la extraccion de agua del subsuelo, que han impuesto deformaciones a los sistemas de tuberias conectados con las instalaciones superficiales que han sido piloteadas en la terminal. De igual modo, otros sistemas de tuberias e instalaciones superficiales presentan deformaciones por hundimientos diferenciales entre sus apoyos.

A comparison of the response of Simocephalus mixtus (Cladocera) and Daphnia magna to contaminated freshwater sediments.

The southeast region of Mexico is characterized by intensive oil industry activities carried out by the national public enterprise Petróleos Mexicanos (PEMEX). The freshwater lagoon "El Limón", located in the municipality of Macuspana, state of Tabasco, Mexico, has received over 40 years discharges of untreated waste waters from the Petrochemical Complex "Ciudad PEMEX", located on the border of the lagoon. To assess the toxicity of the sediments and, hence, to obtain information on the biological effects of these contaminating discharges, the cladoceran Simocephalus mixtus was used as a test organism in acute (48h) and chronic (12d) toxicity assays. For comparison purposes, bioassays were also conducted with the reference cladoceran Daphnia magna. The sediments of this lagoon contain important amounts of metals and hydrocarbons that have been accumulated over time; however, the acute tests only registered reduced lethal effects on the test organisms (maxima of 10% and 17% mortality for D. magna and S. mixtus, respectively). This may be due to low bioavailability of the pollutants present in the sediments. On the other hand, partial or total inhibition and delay in the start of reproduction, reduction in clutch sizes, reduced survival, as well as reduction in the size of adults and offspring were recorded in the chronic assays. The most evident chronic effects were found in S. mixtus; in this species, reproduction was inhibited up to 72%, whereas D. magna was only affected by 24%. We determined that S. mixtus is a more sensitive test organism than D. magna to assess whole-sediment toxicity in tropical environments, and that chronic exposure bioassays are required for an integrated sediment evaluation. The sediments from "El Limón" lagoon induced chronic intoxication responses and, therefore, remediation measures are urgently needed to recover environmental conditions suitable for the development of its aquatic biota.

The 19th International Conference on Electron Dynamics in Semiconductors, Optoelectronics and Nanostructures (EDISON'19) was held at the Hospedería Fonseca (Universidad de Salamanca, Spain), on 29 June - 2 July, 2015, and was organized by the Electronics Area from the University of Salamanca. The Conference is held biannually and covers the recent progress in the field of electron dynamics in solid-state materials and devices. This was the 19th meeting of the international conference series formerly named Hot Carriers in Semiconductors (HCIS), first held in Modena in 1973. In the edition of 1997 in Berlin the name of the conference changed to International Conference on Nonequilibrium Carrier Dynamics in Semiconductors, keeping the same acronym, HCIS; and finally in the edition of Montpellier in 2009 the name was again changed to the current one, International Conference on Electron Dynamics in Semiconductors, Optoelectronics and Nanostructures (EDISON). The latest editions took place in Santa Barbara, USA, in 2011 and Matsue, Japan, in 2013. Research work on electron dynamics involves quite different disciplines, and requires both fundamental and technological scientific efforts. Attendees to the conference come mostly from academic institutions, belonging to both theoretical and experimental groups working in a variety of fields, such as solid-state physics, electronics, optics, electrical engineering, material science, laser physics, etc. In this framework, events like the EDISON conference become a basic channel for the progress in the field. Here, researchers working in different areas can meet, present their latest advances and exchange their ideas. The program of EDISON'19 included 13 invited papers, 61 oral contributions and 73 posters. These contributions originated from scientists in more than 30 different countries. The Conference gathered 140 participants, coming from 24 different countries, most from Europe, but also with a significant participation

Full Text Available Este artículo da a conocer la relevancia de una buena parte del desconocido patrimonio arquitectónico salmantino de la década de 1950. Finalizada la Guerra Civil, el objetivo de la arquitectura se concentró en la reconstrucción y dignificación del país a base de un estilo historicista anacrónico, que fue remitiendo a finales de la década de 1940. Este fue el caso de Salamanca, ciudad en la que la renovación arquitectónica se dio en las tipologías religiosa, doméstica e industrial. Las nuevas obras proyectadas en Madrid se erigieron rápidamente como los modelos a seguir, de las que tuvieron noticia los técnicos bien por conocimiento directo o bien a través de las numerosas publicaciones que se promovieron desde el Estado. Aquellas constituyeron un indudable estímulo y favorecieron el viraje hacia la modernidad, a la que se dio en llamar la «Nueva Arquitectura». Tras el análisis del corpus salmantino, resulta fácil demostrar la voluntad de renovación con la que fue proyectado, así como la distinción de notables ejemplos objeto de estudio, de los que se incorpora referencias archivísticas, hemerográficas y gráficas.This paper offers a view of the importance of Salamanca’s architecture during the Fifties. The situation in Spain in the aftermath of the Civil War change the orientation of the Spanish architecture, so that during the Fifties Salamanca redefined religious, housing and industrial architectural models. Publications were crucial for spreading the modern models but also travelling and studying the buildings in big cities like Madrid. Having this reference, the architects that worked in Salamanca knew how to change from historical design to modern one that are worth to study. The aim of this work is also give detailed newspapers, graphic and archive’s documentation that will show the importance of the architectural heritage of the city of Salamanca in that period.

A New Approach to Energy Calculation of Road Accidents against Fixed Small Section Elements Based on Close-Range Photogrammetry

Alejandro Morales

2017-11-01

Full Text Available This paper presents a new approach for energetic analyses of traffic accidents against fixed road elements using close-range photogrammetry. The main contributions of the developed approach are related to the quality of the 3D photogrammetric models, which enable objective and accurate energetic analyses through the in-house tool CRASHMAP. As a result, security forces can reconstruct the accident in a simple and comprehensive way without requiring spreadsheets or external tools, and thus avoid the subjectivity and imprecisions of the traditional protocol. The tool has already been validated, and is being used by the Local Police of Salamanca (Salamanca, Spain for the resolution of numerous accidents. In this paper, a real accident of a car against a fixed metallic pole is analysed, and significant discrepancies are obtained between the new approach and the traditional protocol of data acquisition regarding collision speed and absorbed energy.

Full Text Available Although later than in English, Linguistics applied to the teaching of Spanish language has produced several didactic dictionaries for foreigners in the last two decades. This dictionaries include grammatical information in order to facilitate pronunciation, and morphological or syntactical comprehension; cultural notions, however, are more difficult to include because they go beyond the scope of the lexicon. Through the analysis of some terms related to folk music and gastronomy, we analyse the inclusion of Spanish and Latin American cultural notions in the three main dictionaries of Spanish for foreigners: the dictionary for the teaching of the Spanish language published by Vox-Alcalá University (Diccionario para la enseñanza de la lengua española, the Salamanca Dictionary (Diccionario Salamanca de la lengua española and the Spanish dictionary for foreigners of SM publishing house (Diccionario de español para extranjeros.

However, the challenge was very appealing to me, first of all because it was an invitation from WIN (Women in Nuclear), which I would like to congratulate, together with the Steering Committee, for having selected Salamanca as the meeting venue in this very important year for this city (it has been selected as European cultural city for 2002, along with the Belgian city of Bruges), If there is any place that has been immersed in scientific culture throughout the centuries it is Salamanca, where every one of its stones could tell us a history of the convergence and divergence between knowledge and society. This Universidad Pontificia of Salamanca also encloses centuries of wisdom within its walls. I have mentioned the first reason for accepting the challenge: the invitation from WIN Espana. The second reason why I accepted is that, some years ago, the world of nuclear energy, them unknown to me, started coming up in conversations with friends, one of whom works in this field. That history of discovery began in a levelly little Swiss town, in Grundenwald, not far from Eintein's Bern, whom I will mention later on.

In agreement with the Secretaria de Energia, Mexico consumed daily in year 2000, 1.7 millions of oil barrels and according to numbers of PEMEX the proven reserves to December 31 of that year, ascended to 12,312 million barrels, obviously the consumption and the reserves will change through the time, but making a calculation these reserves will be sufficient only for 20 years, on the other hand according to PEMEX Gas y Petroquimica Basica numbers, the present natural gas reserves are sufficient to supply the demand during 22 years, with these data we can have an approximate calculation of 20 years of fossil fuel supply, to this stage we can name it the period of power transition, when this time interval is over we will have an eminent power crisis and it will be necessary to count already on new power alternatives, which have a sustainable development and which will have to be ready at by the end of the next 20 years. One of the most viable alternatives is obtaining energy from hydrogen, this is the most abundant element in the universe, near 75% is constituted by it, but it is not found in pure state in nature. In order to determine certain state it is necessary to investigate about the processes for the hydrogen obtaining, the reforming of natural gas, the natural gas reserves, the natural gas distribution and the integrated gasification.

queda claro que las palabras disponibles son palabras muy conocidas, pero no muy frecuentes, a causa de que es necesario tocar un tema específico para que aparezcan (López Chávez, 1994: 69. López Morales (1999: 11 a su vez aduce que se trata de un «caudal léxico utilizable en una situación comunicativa dada», donde por léxico utilizable se entiende el léxico disponible. Los trabajos de disponibilidad léxica son entonces aquellas investigaciones que tienen como objetivo principal conocer el léxico disponible de un grupo determinado de hablantes. «De esta manera el rango de disponibilidad léxica va en función de las palabras que acuden antes a la mente del hablante en relación con un tema determinado» (Galloso Camacho, Prado Aragonés, 2005: 370. El objetivo del presente trabajo es comparar cuantitativa y cualitativamente la disponibilidad léxica de un grupo de alumnos eslovenos de español como lengua extranjera con otras dos investigaciones sobre la disponibilidad léxica en ELE, una llevada a cabo en Finlandia (Carcedo González, 2000 y otra en Salamanca (Samper Hernández, 2002, y consecuentemente detectar las diferencias o similitudes léxicas entre los hablantes extranjeros de español. Seguimos el mismo objetivo que ya expuso Samper Hernández (2002: 17 e igualmente consideramos que «esta comparación podría resultar de gran provecho para el reconocimiento del aprendizaje/adquisición del español como lengua extranjera y puede abrir una vía de investigación que podremos desarrollar en un futuro».

Urencio, Claudio; Sanchez, Luis; Moreno, Carlos [PGPB - Pemex Gas y Petroquimica Basica (Mexico)

2005-07-01

Pemex Gas has 12,134 km of natural gas transmission pipelines, 1,835 Km for LPG and 1,216 Km for basic petrochemicals. The must part of this infrastructure was built in the 70's and reaching their 35 years of operating life. To manage the integrity of the three systems, Pemex Gas has a portfolio of technological tools. This tools allow the Company to improves the decision taking, align the budget with their strategic goals, achieve efficient asset utilization, and increase the value generation. The process of integrity management starts with the risk evaluation on assets, with the use of a software called IAP (Integrity Assessment Program). This information is integrated to the SIIA (Assets Identification System). The results of both software are used to the construction of the Risk Atlas, which identifies graphically each pipeline segment, with their related risk and factors that influence their behavior. The Risk Atlas gives us information about the consequences to the people, environment and facilities, so we can design customized plans to prevent or mitigate emergencies. Finally a detailed analysis of the resulting information and scenarios simulations help us to determine the best investment projects that will minimize the risk through all our assets. (author)

Pigging the unpiggable: a total integrated maintenance approach of the Progreso Process Pipelines in Yucatan, Mexico

Energy Technology Data Exchange (ETDEWEB)

Sanchez Graciano, Luis [PEMEX Refinacion, Mexico, MX (Mexico); Gonzalez, Oscar L. [NDT Systems and Services, Stutensee (Germany)

2009-07-01

Pemex Refinacion and NDT Systems and Services, executed a Total Integrated Maintenance Program of the Process Pipeline System in the Yucatan Peninsula in Mexico, in order to modernize, enhance and bring the pipeline system up to the best industry standards and ensure the integrity, reliability and safe operation of the system. This approach consisted in using multi-diameter ultrasonic inspection technology to determine the current status of the pipelines, repair every 'integrity diminishing' feature present on the system and establish a Certified Maintenance Program to ensure the future reliability and safety of the pipelines. Due to the complex nature of the pipeline construction, dated from 1984, several special modifications, integrations and solutions were necessary to improve the in line inspection survey as for all traditionally unpiggable systems. The Progreso Pipeline System consists in 3 major pipelines which transport diesel, jet fuel and gasoline respectively. The outside diameter of two pipelines varies along its length between 12 inches - 14 inches - 16 inches, making the inspection survey more difficult and particularly demanding an Inspection Tool solution. It is located on the coast of the Yucatan Peninsula, at the Mexican Caribbean, and its main purpose is to transport the product from the docked tanker ships to the Pemex Storage and Distribution Terminal.

2001-07-01

It was verified the use of environmental isotopes as a useful method to improve the efficiency of the present exploitation in oil fields of the Gulf of Mexico. In general, the stable isotopes like deuterium, 18 O, 13 C, 37 Cl, 87 Sr and 34 S, support in questions on the origin of waters, its quality, the geochemistry evolution, recharge processes, interaction water-rock, origin of the salinity and contamination processes, whereas the radioactive isotopes (Tritium, 14 C, 36 I and 129 I) provide information on the time of circulation, the origin and the age of underground waters. Since year 1998, the Gerencia de Geotermia of the Instituto de Investigaciones Electricas is making investigation projects in the oil fields of the Actives of Production Luna, Pol-Chuc, Chilpilla-Colomo (all of them in the state of Tabasco) and Cactus-Sitio Grande (Chiapas) in the South Region of PEMEX Exploration and Production (PEP). As primary target of these studies hidrogeological models were developed on the migration and circulation of the fluids in the oil fields with the purpose of limiting the water invasion in producing wells and to increase the crude oil production. [Spanish] Se comprobo el uso de los isotopos ambientales como un metodo util para mejorar la eficiencia de la explotacion actual en yacimientos petroleros del golfo de Mexico. En general, los isotopos estables como deuterio, 18 O, 13 C, 37 Cl, 87 Sr y 34 S, apoyan en cuestiones sobre el origen de las aguas, su calidad, la evolucion geoquimica, procesos de recarga, interaccion agua-roca, origen de la salinidad y procesos de contaminacion, mientras que los isotopos radiactivos (Tritio, 14 C, 36 l Y 129 I) proporcionan informacion sobre el tiempo de circulacion, el origen y la edad de las aguas subterraneas.

Derechos de propiedad e industria petrolera mexicana

Directory of Open Access Journals (Sweden)

Rosío Vargas

2013-01-01

Full Text Available De un control de los recursos mineros a fines del siglo antepasado, por parte de las corporaciones internaciona- les, la industria petrolera mexicana transitó a un régimen de soberanía nacional y propiedad pública del petróleo después de 1938 que le permitió el diseño de una política económica con vocación nacional asignando varias tareas a PEMEX. La adopción del modelo neoliberal en los ochenta, como fundamento de la estrategia macroeco- nómica, fue el punto de retorno al control privado de la industria y la empresa petrolera. Con la puesta en opera- ción del modelo neoliberal se desmantela la integración vertical lograda años atrás, se obliga a PEMEX a endeu- darse para poder realizar sus inversiones, y se confiscan los recursos fiscales de la empresa. Bajo el argumento de que es preferible exportar más ahí donde es viable multiplicar los aportes a la balanza de pagos e importar pro- ductos que la competencia internacional ha abaratado, no sólo se regresa a un modelo especializado en la pro- ducción de una materia prima en detrimento de los sectores industriales, sino que se renuncia a la autosuficiencia energética llevando al país a una peligrosa dependencia estratégica de derivados del petróleo. Bajo la dinámica de la integración en América del Norte liderada por los Estados Unidos, se logra la apertura total en los sectores corriente arriba de la empresa petrolera mexicana. El regreso a la propiedad privada es visible a partir de los contratos negociados en la reforma energética de 2008, y la desincorporación de actividades sustantivas de la industria que constituyen prerrogativas constitucionales, la empresa se encamina bajo una dinámica de gobernanza corporativa a la conformación legal de una corporación privada por lo que un cambio mayor surge con la ruptura del binomio Estado- PEMEX.

Magnitude and extent of land subsidence in central Mexico revealed by regional InSAR ALOS time-series survey

Science.gov (United States)

Chaussard, E.; Wdowinski, S.; Amelung, F.; Cabral-Cano, E.

2013-05-01

Massive groundwater extraction is very common in Mexico and is well known to result in land subsidence. However, most surveys dedicated to land subsidence focus on one single city, mainly Mexico City, and thus fail to provide a comprehensive picture of the problem. Here we use a space-based radar remote sensing technique, known as Interferometric Synthetic Aperture Radar (InSAR) to detect land subsidence in the entire central Mexico area. We used data from the Japanese satellite ALOS, processed over 600 SAR images acquired between 2007-2011 and produced over 3000 interferograms to cover and area of 200,000 km2 in central Mexico. We identify land subsidence in twenty-one areas, including seventeen cities, namely from east to west, Puebla, Mexico city, Toluca de Lerdo, Queretaro, San Luis de la Paz, south of San Luis de la Paz, Celaya, south of Villa de Reyes, San Luis Potosi, west of Villa de Arista, Morelia, Salamanca, Irapuato, Silao, Leon, Aguascalientes, north of Aguascalientes, Zamora de Hidalgo, Guadalajara, Ahuacatlan, and Tepic. Subsidence rates of 30 cm/yr are observed in Mexico City, while in the other locations typical rates of 5-10 cm/yr are noticed. Regional surveys of this type are necessary for the development of hazard mitigation plans and efficient use of ground-based monitoring. We additionally correlate subsidence with land use, surface geology, and faults distribution and suggest that groundwater extraction for agricultural, urban, and industrial uses are the main causes of land subsidence. We also reveal that the limits of the subsiding areas often correlate with existing faults, motion on these faults being driven by water extraction rather than by tectonic activity. In all the subsiding locations we observe high ground velocity gradients emphasizing the significant risks associated with land subsidence in central Mexico. Averaged 2007-2011 ground velocity map from ALOS InSAR time-series in central Mexico, revealing land subsidence in 21

Nuevos santuarios rupestres prehistóricos en las provincias de Zamora y Salamanca

Full Text Available RESUMEN: En el presente artículo se dan a conocer varios santuarios rupestres prehistóricos inéditos. Todos ellos forman parte de un conjunto de centros cultuales distribuidos por el centro-oeste de España, aunque estrechamente relacionados con otros existentes en el ámbito galaico y en la Celtiberia. Es probahle que, en algunos casos, haya habido pervivencias en el mundo romano, pero lo que define su ceremonial y su liturgia —aparte, claro está, su simbolismo— pertenece a una época anterior. De ahí el que, como ya hemos consignado en otras ocasiones, adscribamos al mundo prehistórico y protohistórico la existencia de tales monumentos religiosos. Como novedad, dentro del conjunto de santuarios que aquí presentamos, aparecen, en uno de ellos, representaciones de manos y del aparato genital masculino. Otro de los que hemos estudiado, muestra una gran profusión de hoyuelos, de lo cual ofrecemos una interpretación. Nuestra tesis es que es preciso recurrir a la investigación de la simbologia primaria, precisamente aquélla que, según todos los indicios, marcaba las pautas de representación principales del hombre en la Antigüedad.ABSTRACT: In this article, we offer a study of various prehistoric rupestrian shrines which have been unknown until now. They all belong to a collection of cult centres spread around the west-centre of Spain; although they are closely related to others which have been discovered in the region of Galitis and in Celtiberia. It is probable that, in certain cases, these centres existed as such during the Roman Empire but those features characteristic of their ceremonial and liturgical rites —apart from their symbolism— belong to previous times. That is why, as we have set down in previous occasions, we adscribe the existence of such religious monuments to the prehistoric and protohistoric world. Within the collection of shrines that we present here, there are several new features such as the

Full Text Available La Escuela Regional de Artes y Oficios de Béjar (Salamanca inició su andadura en 1886, aunque sus precedentes pueden ser rastreados desde 1852 en la Escuela Industrial. Béjar por aquel entonces podía presumir de ser uno de los escasos centros fabriles del oeste español, con una industria textil renqueante que subsistía a pesar de los embates de la crisis. La enseñanza técnica impartida en el centro educativo bejarano pretendía insertar a los trabajadores en el entorno laboral. El presente artículo intenta aportar una nueva perspectiva a la etapa comprendida entre 1886 y 1901 manejando nuevos datos procedentes del archivo de la propia institución, hasta ahora prácticamente inéditos, a la par que reflexionar sobre el contexto histórico, social y económico de la ciudad fabril.

This study was subsidized by the Ministry of Education and Science and performed by GITE-USAL (Group of Investigation-innovation of Educational Technology of the Salamanca University. The contributions of the Information and Communication Technologies are analyzed to improve the didactic processes related to the methodological change proposed by the European Program of Higher Education. The tutorship is considered a basic strategy for the students’ guidance, individualization and pursuit of learning in any pedagogic model. Yet this is even more apparent when we attempt methodologies that give the students more autonomy, as with the credits of the ECTS and the ICTs. These are appreciated as important and valuable resources to achieve the proposed ends. The good practices conflict with the difficulties of time, space, number of students, recognition of educational activity, etc. These indicate that the professors are factors of the current situation and can stand in the way of a true change towards greater learning and an increase in didactic efficacy Los profesores universitarios intercambian opiniones sobre la tutoría en un seminario virtual desarrollado en la Universidad de Salamanca (marzo de 2007 en el marco del proyecto de investigación TICDUS, subvencionado por el Ministerio de Educación y Ciencia, en el que está trabajando el grupo GITE-USAL (Grupo de Investigación-Innovación de Tecnología Educativa de la Universidad de Salamanca.

Yucatán subsurface stratigraphy: Implications and constraints for the Chicxulub impact

Science.gov (United States)

Ward, W. C.; Keller, G.; Stinnesbeck, W.; Adatte, T.

1995-10-01

Much of the discussion about the effects of an end-of-Cretaceous impact by a large extraterrestrial body in northwestern Yucatán has been done in the context of limited and partly erroneous published data on the Mesozoic stratigraphy of that area. Reexamination of cores and geophysical logs taken in several Pemex wells has produced improved lithologic and biostratigraphic correlation of the Jurassic to Maastrichtian section across the northern Yucatán peninsula. These data suggest that major disturbance of strata by an impact would have been confined to within about 100 km of the proposed impact center near Chicxulub. The only unusual lithologic unit is polymict breccia, which apparently was penetrated at or near the top of the Cretaceous section in all the deep wells of northern Yucatán. This breccia in Pemex wells Yucatán 1, 2, 4, 5A, and 6 is composed predominantly of detrital dolomite, limestone, and anhydrite clasts set in dolomitized carbonate mud matrix, which contains upper Maastrichtian foraminifers. These constituents, mixed with fragments of altered glass or melt rock, shocked quartz and feldspar, and basement rock, suggest an impact as the most likely origin for the breccia. The timing of brecciation is poorly constrained by biostratigraphic data. There is some evidence, however, that the breccia unit is overlain by about 18 m of uppermost Maastrichtian marls, suggesting an impact before the Cretaceous-Tertiary boundary. In addition, there may have been more than one episode of breccia deposition.

Full Text Available El objetivo de este trabajo es analizar dos versiones en lengua española realizadas a partir del álbum ilustrado originalmente escrito en inglés The story of Ferdinand (1935 por Munro Leaf e ilustrado por Robert Lawson. La comparación de este tipo específico de narrativa se establece entre dos traducciones al castellano y sus ilustraciones cuya fecha de publicación dista más de 30 años y cuyo lugar de publicación está separado por el océano Atlántico Norte (una americana de 1962 y otra española de 1994. Este artículo presta especial atención a la relación multimodal que se establece entre el código semiótico visual y escrito de ambas versiones españolas de cara a dilucidar la distinta orientación ideológica que cada traducción asume al dirigirse a un público receptor, principalmente de carácter infantil. La obra fue escrita a las puertas del estallido de la Guerra Civil española, donde ya sabemos por la historia que la oleada de violencia había llegado a unos extremos de gran crudeza. Es interesante indagar en la actualidad que cobra en España este álbum ilustrado de origen americano al poco de publicarse con el estallido de la Guerra Civil española y, poco después, en el continente Europeo con la 2ª Guerra Mundial. Haciendo un uso metafórico de una fiesta tradicional española caracterizada también por su violencia y crueldad, la imaginería y la traducción de cada versión en castellano dan respuesta a unas motivaciones comunicativas (Moya y Pinar, 2007, p.22 que condicionan la recepción del texto en el lector y cultura meta. This paper aims to analyze two Spanish editions of the picture book The story of Ferdinand (1935 written by Munro Leaf and illustrated by Robert Lawson. The comparison of this specific narrative type is made between two translations into Spanish and their illustrations whose release dates are more than 30 years apart and that were published on both shores of the North Atlantic Ocean (one in North America in 1962 and the other in Spain in 1994. Special attention is paid to the multimodal interplay between the visual representations and written language in both Spanish translations in order to elucidate the distinct ideological approach adopted by each edition to address the target audience, mainly children. The picture book was written just before the onset of the Spanish Civil War, where history has shown that violence reached extreme levels. It is interesting to look into how this picture book updates its significance with the outbreak of the Spanish Civil War and, a little later, of the Second World War in Europe. Through a metaphorical use of the Spanish traditional spectacle also characterized by its violence and cruelty, the imagery and the text of each Spanish edition satisfies some specific communication needs (Moya y Pinar, 2007, p. 22 that determine the reception of a text in the target culture and reader.

Assessment of the oral health-related quality of life and the modulating factors of patients demanding dental treatment in the city of Salamanca, through the use of two validated instruments: the OIDP-sp (Oral Impacts on Daily Performance) and OHIP-14 (Oral Health Impact Profile). the study was conducted on a consecutive sample of 200 patients aged 18-65 years visiting an Integral Dental Centre in the city of Salamanca. Two validated instruments (OIDP-sp and OHIP-14) were used to measure the oral health-related quality of life. An analogue visual scale was used to register oral satisfaction. Data on sociodemographic background, behavioural and clinical factors were also gathered. ANOVA, T Student Test, and both Pearson and Spearman correlations coefficients were used for the statistical analysis. according to the OIDP, 68.5% suffered from some kind of impact in their oral quality of life, while impact prevalence with the OHIP was 85%. Some other factors influencing the quality of life and degree of satisfaction were revealed. patients over 45 years, regardless of their gender, from high social class, living in rural areas and with poor hygiene, showed higher impact and lower satisfaction. The study also revealed some clinical conditions closely related to the level of satisfaction.

Crooked lines 2D seismic reflection, covering a portion near the intersection of CPF and CPGF are processed and interpreted. The seismic data were obtained in the early 80's by Petróleos Mexicanos (PEMEX). By decades, technical and investigation works in Cerro Prieto geothermic field and its vicinity had mapped faults at several depths but do not stablish a clear limit where this faults and CPF interact due the complex hydrothermal effects imaging the subsurface. The profiles showing the presence of a zone of uplift effect due to CPF. Considering the proximity of the profiles to CPF, it is surprising almost total absence of faults. A strong reflector around 2 km of depth, it is present in all profiles. This seismic reflector is considered a layer of shale, result of the correlation with a well located in the same region.

Cloud point extraction has been used for the preconcentration of uranium, prior to its determination by flow injection. The non-ionic surfactant employed was Triton X-114 and the reagent chosen to form a hydrophobic chelate of uranium was 1-(2-pyridylazo)-2-naphthol. The optimum conditions for the preconcentration and determination of uranium have been studied. This methodology has been applied to the determination of trace amounts of uranium in tap and river waters from Salamanca. (Author).

Thinking regionally: narrative, the medical humanities and region.

Science.gov (United States)

Waddington, Keir

2015-06-01

Drawing on multiple literatures from history, geography, anthropology, sociology and literature, this essay asks questions about what we mean by region and why narratives of region should matter to the medical humanities. The essay surveys how region can be used as a lens of analysis, exploring the various academic approaches to region and their limitations. It argues that regions are dynamic but also unstable as a category of analysis and are often used uncritically by scholars. In encouraging scholars working in the medical humanities to be aware that regions are not simple objective or analytical boxes, the essay shows how an awareness of region helps challenge metropolitan whiggism and ideas of core and periphery to give a more prominent place to hinterlands, market towns and rural environments. Furthermore, the essay considers how incorporating region into our understanding of illness can offer new insights. It demonstrates the need for scholars to be attuned to the narratives constructed around regions, suggesting that regions can be viewed as discursive formations that provide a frame for understanding both collective and personal ideas of, and responses to, health and illness, disease and healing, to create what Megan Davies calls a more nuanced 'intellectual cartography'.

Development of regional growth centres and impact on regional growth: A case study of Thailand’s Northeastern region

Directory of Open Access Journals (Sweden)

2013-01-01

Full Text Available This study investigates the spatial economic structure and inequality in Thailand at the national and regional levels, with a particular focus on the Northeastern region in the period from 1987 to 2007. The study has three main points: 1 examination of the economic structure and inequality at the national level and in the Northeastern region according to the Theil index, 2 determination of regional growth centres and satellite towns by using growth pole theory as a conceptual framework and incorporating spatial interaction analysis and 3 analysis of the relationship between regional growth centres and satellite towns with regard to the impact on growth and inequality. The results show that the Northeastern region is definitely the lagging region in the nation, by both gross domestic product (GDP and gross regional product (GRP per capita. It was therefore selected for a case study. Spatial analysis identified Nakhon Ratchasima, Khon Kaen, Udon Thani and Ubon Ratchathani as regional growth centres. Each of them has its own sphere of influence (or satellite towns, and the total area of regional growth centres and satellite towns are classified as sub-regions. The development of regional growth centres has a direct impact on sub-regional economic growth through economic and social relationships: urbanisation, industrial development, per capita growth, the number of higher educational institutes and so on. However, such growth negatively correlates with economic equality among the provinces in a sub-region. The inequality trend is obviously on an upswing. This study suggests that industrial links between regional growth centres and their satellite towns should be improved in order for regional growth centre development to have a consistently desirable effect on both economic growth and equality. Such a strong process means that the growth of regional growth centres will spread, leading to the development of their surrounding areas.

Full Text Available The paper analyzes findings yielded by the empirical study performed in the framework of an RGNF grant entitled “Image of a region as a communicative strategy for the authorities and mass media”. The methods of study included expert survey and formal survey (N=1000, July-September 2013, studying the opinion of respondents who were either internal experts residing in the Volgograd region (N=20; May-September 2013 or external experts who reside outside the region but maintain stable ties with the representatives of state and municipal authorities, regional mass media and business. The findings indicate that the Volgograd region has fallen behind other modernized Russian regions, that young people tend to leave it, that a negative image of the region as a declining territory persists. Answers to the open question “What is unacceptable for you in the existing image of the Volgograd region?” revealed major problems determining the local context of a declining region, and those were issues associated with inefficient regional/municipal administration: “the condition of the roads”, “constant replacement of people in the administration”, “politics as a whole”, “a destitute region without a good manager”, “unemployment”, “countryside is dying off”, “indifference of the authorities”, “roads, housing and public utilities and the administration”, “the authorities are not responsible for the people”, “the authorities do not solve the problems of the city or its people”, “thieving”, “dishonest authorities”, “the region goes to rack and ruin, no kindergartens or jobs”, “one cannot even walk in the streets”, “corruption”, “a stagnant region with low pay”, “no perspectives in the future”, “the region is stagnating due to corruption among officials”. According to the local Census Bureau, the Volgograd region can be classified as a declining territory where the population decline

In this article the results of the analysis of recurrent faults of four Generating Units of Thermoelectric Power Plants (UGT) of the Commission Federal de Electricidad (CFE) are presented. In three of the four cases, the studies focused to identify and to correct the root causes of recurrent faults in steam generator tubes, the analyzed units are: U-2 of the Thermoelectric Complex Pdte. Adolfo Lopez Mateos (CTPALM) of Tuxpan, Veracruz; U-3 of the Salamanca Thermoelectric Power Plant (TPP), and U-1 and 2 of the Thermoelectric Power Plant (TPP) Felipe Carrillo Puerto of Valladolid, Yucatan. In the other case the combinations air insufficiency was analyzed as one of the causes of decrement of power of the Unit 1 of the TPP Gral. Manuel Alvarez Moreno of Manzanillo, Colima. The steam generators of Unit 2 of the CTPALM and Unit 3 of the TPP of Salamanca presented faults in the reheater (RH) bank. In this case the recommendations focused to the improvement in the operative conditions to attenuate the faults by corrosion at high temperature. Unlike the CTPALM, in the case of U-3 of Salamanca it was concluded that the redesign of the RH was necessary; for this purpose it was proposed to permute trajectories of hot tubes with the cold ones to make the steam temperature uniform at the RH outlet. In order to evaluate the problems that have appeared in the steam generator of Units 1 and 2 of the TPP Felipe Carrillo Puerto of Valladolid, Yucatan the faults of the tubes of water wall were analyzed and it was found that the main mechanism of overheat is due to the impact of the combustion flame. In the study of the Unit 1 of the TPP Gral. Manuel Alvarez Moreno of Manzanillo, Colima, a methodology was developed to quantify the contribution that the main equipment has in the decrement of the power of the unit; this methodology consists of applying a process of computational simulation based in the design conditions and of real operation.

Full Text Available Talc mineralization related to the ultramafic bodies of the Río de Las Tunas belt, Frontal Cordillera of Mendoza province. This contribution shows the main characteristics of the talc mineralization related to the Río de Las Tunas ultramafic bodies in the Salamanca Mining District, Frontal Cordillera of Mendoza province. According to the parageneses defined on the studied samples, three generations of talc were established: 1º crystallized in metaperidotites and related to the prograde stage of the regional metamorphism; 2º crystallized inreaction zones (mostly in the talc zone developed at the boundary between metaperidotites and their country-rocks.These reaction zones evidence a metasomatic process due to geochemical gradient between the ultramafic body and their country-rocks. This process was developed during the retrogression of the regional metamorphic cycle. 3º Talc present in shear-zones that cut across the ultramafic bodies. The extreme serpentinization of the ultramaficbodies is concentrated in shear-zones where the serpentine is subsequently replaced by talc ± carbonates related with a hydrothermal stage. Aqueous fluids relatively enriched in CO2 flowed through these shear-zones causing the cease of serpentine formation favoring the talc and/or carbonates. Mined talc deposits are those in shear zones and reaction zones. They are mostly industrial-, asbestine- or talcschist-type. The talc related to the hydrothermal stage can locally reach first and extra qualities.

Data were drawn from 17 semi-structured interviews of state, regional, and municipal health policymakers and managers; a focus group; observations of the regional interagency committee; and documents in 2012. The political-institutional and the organizational components were analyzed in the light of dialectical hermeneutics. RESULTS The regional interagency committee is the chief regional governance strategy/component and functions as a strategic tool for strengthening governance. It brings together a diversity of members responsible for decision making in the healthcare territories, who need to negotiate the allocation of funding and the distribution of facilities for common use in the region. The high turnover of health secretaries, their lack of autonomy from the local executive decisions, inadequate technical training to exercise their function, and the influence of party politics on decision making stand as obstacles to the regional interagency committee’s permeability to social demands. Funding is insufficient to enable the fulfillment of the officially integrated agreed-upon program or to boost public supply by the system, requiring that public managers procure services from the private market at values higher than the national health service price schedule (Brazilian Unified Health System Table. The study determined that “facilitators” under contract to health departments accelerated access to specialized (diagnostic, therapeutic and/or surgical services in other municipalities by direct payment to physicians for procedure costs already covered by the Brazilian Unified Health System. CONCLUSIONS The characteristics identified a regionalized system with a conflictive pattern of

Analysis of regional climate strategies in the Barents region

Energy Technology Data Exchange (ETDEWEB)

Himanen, S.; Inkeroeinen, J.; Latola, K.; Vaisanen, T.; Alasaarela, E.

2012-11-15

Climate change is a global phenomenon with especially harsh effects on the Arctic and northern regions. The Arctic's average temperature has risen at almost twice the rate as elsewhere in the past few decades. Since 1966, the Arctic land area covered by snow in early summer has shrunk by almost a fifth. The Barents Region consists of the northern parts of Norway, Sweden, Finland and Russia (i.e. the European part of Russia). Climate change will cause serious impacts in the Barents Region because of its higher density of population living under harsh climatic conditions, thus setting it apart from other Arctic areas. In many cases, economic activities, like tourism, rely on certain weather conditions. For this reason, climate change and adaptation to it is of special urgency for the region. Regional climate change strategies are important tools for addressing mitigation and adaptation to climate change as they can be used to consolidate the efforts of different stakeholders of the public and private sectors. Regional strategies can be important factors in achieving the national and international goals. The study evaluated how the national climate change goals were implemented in the regional and local strategies and programmes in northern Finland. The specific goal was to describe the processes by which the regional strategies were prepared and implemented, and how the work was expanded to include the whole of northern Finland. Finally, the Finnish preparatory processes were compared to case examples of processes for preparing climate change strategies elsewhere in the Barents Region. This analysis provides examples of good practices in preparing a climate change strategy and implementing it. (orig.)

Drug-loaded erythrocytes can operate through one of the three main mechanisms of action: extension of circulation half-life (bioreactor, slow drug release, or specific organ targeting. Although the clinical development of erythrocyte carriers is confronted with regulatory and development process challenges, industrial development is expanding. The manufacture of this type of product can be either centralized or bedside based, and different procedures are employed for the encapsulation of therapeutic agents. The major challenges for successful industrialization include production scalability, process validation, and quality control of the released therapeutic agents. Advantages and drawbacks of the different manufacturing processes as well as success key points of clinical development are discussed. Several entrapment technologies based on osmotic methods have been industrialized. Companies have already achieved many of the critical clinical stages, thus providing the opportunity in the future to cover a wide range of diseases for which effective therapies are not currently available.Keywords: red blood cell, encapsulation method, drug carrier, industrial development, clinical use

Field-aligned current signatures in the near-tail region. 2. Coupling between the region 1 and region 2 systems

International Nuclear Information System (INIS)

Ohtani, S.; Kokubun, S.; Nakamura, R.; Elphic, R.C.; Russell, C.T.; Baker, D.N.

1990-01-01

The development of the substorm-associated current system in the near-tail region is examined in the light of both experiment and theory. First, the March 28, 1979, event is examined intensively by using ground magnetometer data and satellite magnetic field and energetic particle data. The comparison of field-aligned current signatures at geosynchronous altitude and in the near-tail region indicates that the development of the region 1 system is not merely the enhancement in current intensity of the pre-existing system. This finding is consistent with the so-called current wedge model, in which the tail current is converted into a pair of field-aligned currents with the region 1 polarity at substorm onsets. Detailed inspection, however, suggests that the region 2 system is as important as the region 1 system. Statistical properties of the azimuthal magnetic component at synchronous orbit indicate that the deviation during disturbed periods is larger than expected from the enhancement of the region 1 current. These individual and statistical studies suggest that the region 2 system tends to develop in the synchronous region and that the coupling between the region 1 and the region 2 systems is important. The current closure in the magnetosphere is discussed from a viewpoint of the macroscopic behavior of plasma. It is suggested that the dawnside and the duskside region 2 currents are closed in the magnetosphere by the curvature current during the growth phase and by the magnetic gradient current during the expansion phase. The field-aligned currents of the region 1 and the region 2 systems are closed in the ionosphere by the Pedersen current. Consequently, the energy is dissipated as the Joule heating and this energy must be supplied from the magnetosphere. Therefore, the counter part of the Pedersen current, which closes the region 1 and the region 2 currents in magnetosphere, must be the dynamo current

The goal of this study is predicting human age using neuro-metrics derived from structural MRI, as well as investigating the relationships between age and predictive neuro-metrics. To this end, a cohort of healthy subjects were recruited from 1000 Functional Connectomes Project. The ages of the participations were ranging from 7 to 83 (36.17+/-20.46). The structural MRI for each subject was preprocessed using FreeSurfer, resulting in regional cortical thickness, mean curvature, regional volume and regional surface area for 148 anatomical parcellations. The individual age was predicted from the combination of regional and inter-regional neuro-metrics. The prediction accuracy is r = 0.835, p Pearson correlation coefficient between predicted ages and actual ages. Moreover, the LASSO linear regression also found certain predictive features, most of which were inter-regional features. The turning-point of the developmental trajectories in human brain was around 40 years old based on regional cortical thickness. In conclusion, structural MRI could be potential biomarkers for the aging in human brain. The human age could be successfully predicted from the combination of regional morphometry and inter-regional morphological similarity. The inter-regional measures could be beneficial to investigating human brain connectome.

Regional profile, energy-impacted communities: Region VIII

Energy Technology Data Exchange (ETDEWEB)

None

1979-03-01

This report has data on population, administration, finance, housing, health and safety, human services, education, and water and sewage for 325 energy-impacted communities. A review of current and potential energy developments in the region shows over 900 energy resource impacts listed for the 325 impacted communities. Coal development represents over one-third of the developments listed. Communities reporting coal development are distributed as follows: Colorado (36), Montana (42), North Dakota (61), South Dakota (13), Utah (73), and Wyoming (35). Energy-conversion initiatives represent another high incidence of energy-resource impact, with uranium development following closely with 83 communities reporting uranium development impact in the region. These projections indicate continued development of regional energy resources to serve national energy requirements. The 325 impacted communities as reported: Colorado (46), Montana (73), North Dakota (62), South Dakota (21), Utah (80), and Wyoming (43) follow a distribution pattern similar to that of future projects which illustrates that no area of the region will escape the impacts of energy development.

1979-01-01

Left ventricular regional ejection fractions were derived from background-corrected, time-activity curves in 43 patients assessed by both gated equilibrium radionuclide angiocardiography and left ventricular contrast angiography. From a single, modified left anterior oblique projection, the regional change in background corrected counts was determined in each of three anatomic regions. The normal range for regional radionuclide ejection fraction was determined in 10 patients with normal contrast ventriculograms and without obstructive coronary artery disease at coronary arteriography. Regional ejection fraction was compared with percent segmental axis shortening and extent of akinetic segments in corresponding regions of the contrast ventriculogram. Radionuclide and roentgenographic methods were in agreement as to the presence or absence of abnormal wall motion in 83 of 99 left ventricular regions (84%) in 33 patients evaluated prospectively. Comparison of regional ejection fraction demonstrated significant differences between regions with roentgenographically determined normokinesis hypokinesis, and akinesis. We conclude that the left ventricular regional ejection fraction provides a reliable quantitative assessment of regional left ventricular performance

REGIONAL BLACK SEA ARCHITECTURE AND CONSEQUENCES FOR THE REGIONAL COOPERATION FRAMEWORK

2010-12-01

Full Text Available Sometimes considered an asset, other times a liability, the Black Sea started recently to be regarded as a region. However, the Black Sea Region lacks a common vision, often due to the complicated and often inefficient nexus of regional cooperation initiatives. Following the logic of finding regional solutions for regional problems, this paper aims to assess existing institutional and regional initiatives, reflecting on the implications for the success of Black Sea regionalism in creating patterns of sustained and sustainable development and a high degree of actors' involvement.This paper concentrates on two complementary research questions: What is the regional order in the BSR and what does it imply for its future? What is the current contribution of the most significant cooperation initiatives and what are the consequences for regional institutionalism? For the purpose of this paper, I draw on best-practices from other two regions: the Northern Dimension and South- East Asia. Through a comparative perspective, I suggest an analysis of the most important initiatives: BSEC, CDC, Black Sea Synergy, Eastern Partnership, Baku Initiative and the BSF. This paper argues that a possible strategic solution for successful policy development lies in the creation of an integrated regional cooperation package, functioning on the principles of multi-speed and multi-dimensional cooperation in several policy fields, in a context in which the BSR seems to be caught between two paradigms: a European and a Russian-oriented one.

Reverse polarity magnetized melt rocks from the Chicxulub impact structure, Yucatan Peninsula, Mexico

1993-03-01

Further paleomagnetic data for core samples of melt rock recovered in the Petroleos Mexicanos (PEMEX) exploratory wells within the Chicxulub structure, northern Yucatan peninsula, Mexico are reported. A previous report by Sharpton showed that the rocks studied contain high iridium levels and shocked breccia clasts, and an Ar-40/Ar-39 age of 65.2 plus or minus 0.4 Ma. The geomagnetic polarity determined for two samples is reverse (R) and was correlated with chron 29R that includes the K/T boundary. Our present analysis is based on two samples from each of three clasts of the melt rock from PEMEX well Y6-N17 (1295 to 1299 m b.s.l.). This study concentrates on the vectorial nature and stability of the remanence (NRM), the magnetic mineralogy and remanence carriers (i.e., the reliability and origin of the record), and on the implications (correlation with expected paleolatitude and polarity). The relative orientation of the drill core samples with respect to the horizontal is known. Samples were stable under alternating field (AF) and thermal treatments, and after removal of a small component they exhibited single-vectorial behavior. The characteristic remanence inclinations show small dispersion and a mean value (-43 deg) in close agreement with the expected inclination and paleolatitude (derived from the North American apparent polar wander path). Isothermal remenence (IRM) acquisition experiments, Lowrie-Fuller tests, coercivity and unblocking temperature spectra of NRM and saturation IRM, susceptibility and Q-coefficient analyses, and the single-component nature indicate a dominant mineralogy of iron-rich titanomagnetites with single or pseduo-single domain states. The stable characteristic magnetization may be interpreted as a result of shock heating of the rock at the time of formation of the inpact structure and its polarity, age, and paleolatitude are consistent with a time about the K/T boundary.

Esteller, M V; Rodríguez, R; Cardona, A; Padilla-Sánchez, L

2012-09-01

The impact of intensive aquifer exploitation has been observed in numerous places around the world. Mexico is a representative example of this problem. In 2010, 101 out of the 653 aquifers recognized in the country, showed negative social, economic, and environmental effects related to intensive exploitation. The environmental effects include, among others, groundwater level decline, subsidence, attenuation, and drying up of springs, decreased river flow, and deterioration of water quality. This study aimed at determining the hydrochemical changes produced by intensive aquifer exploitation and highlighting water quality modifications, taking as example the Valle de Toluca, Salamanca, and San Luis Potosi aquifers in Mexico's highlands. There, elements such as fluoride, arsenic, iron, and manganese have been detected, resulting from the introduction of older groundwater with longer residence times and distinctive chemical composition (regional flows). High concentrations of other elements such as chloride, sulfate, nitrate, and vanadium, as well as pathogens, all related to anthropogenic pollution sources (wastewater infiltration, irrigation return flow, and atmospheric pollutants, among others) were also observed. Some of these elements (nitrate, fluoride, arsenic, iron, and manganese) have shown concentrations above Mexican and World Health Organization drinking water standards.

Recurrent Forbush decreases and relationship between active regions and M-regions

International Nuclear Information System (INIS)

Shah, G.N.; Kaul, C.L.; Razdan, H.; Bemalkhedkar, M.M.

1977-01-01

Recurrent Forbush decreases and recurrent geomagnetic disturbances have been attributed to the solar M-regions, which are sources of high velocity solar plasma streams. A study of recurrent Forbush decreases for the period 1966-75 has been made to examine any possible relationship of M-regions with solar active regions. It is shown that at the onset of the recurrent Forbush decrease at earth, there is a high probability of encountering a class of active regions at central meridian of the sun which give rise to flares of importance >= 28/3N. These active regions are found to be long-lasting and to have large areas as well as high Hsub(α)-intensities. Other active regions, producing flares of only lower importance, are distributed randomly on the sun with respect to the onset of a recurrent Forbush decrease. Using the quasiradial hypervelocity approximation, the base of the leading edge of the high velocity stream, at the onset of a recurrent Forbush decrease at earth, is traced to the solar longitude about 40 deg West of the central meridian. From these results, it is deduced that M-regions are located preferentially to the West of long-lasting, magnetically complex active regions. Earlier studies of the identification of the M-regions on the sun have been re-examined and shown to conform to this positional relationship. A possible mechanism of the development of an M-region to the West of the long-lasting magnetically complex active region is also discussed. (author)

Gamma radiation effects on the rheological properties of high and low density polyethylenes

International Nuclear Information System (INIS)

Rangel-Nafaile, C.; Garcia-Rejon, A.; Garcia Leon, A.

1986-01-01

High energy radiation of polymeric materials is a topic of considerable interest from commercial and scientific points of view. Within an inert atmosphere, irradiation of polyethylene yields a crosslinking effect with a consequent improvement in its mechanical properties in comparison to the virgin materials. Additionally, if irradiated specimens are melted and recrystallized, the radiation-induced crosslinking hinders their crystalline growth altering dramatically their flow properties such as the elasticity. This work portrays the effects of the gamma radiation on the rheological properties of high and low density polyethylenes manufactured by PEMEX and analyzes the implications of theoretical results derived from the Acierno's model when it is implemented with the rheological properties of high energy irradiated polyethylenes.

This paper reports that Mexico's National Science Council (NSC) has made a strong appeal to strengthen Mexico's efforts in science. The energy sector is given special treatment, and NSC urges the federal administration to take a sharper look at the medium and long term implications of its modernization plans. The council urges greater efforts at energy conservation and encourages Mexico's State Petroleum Institute (IMP) to develop the horizontal drilling techniques that Pemex currently obtains only from foreign contractors. Aside from the value of NSC's well-intended advice to the IMP, the council's vision of the energy challenge of Mexico - and of the specific role the petroleum sector within that challenge - is narrowly conceived

Cytogenetic analysis was performed on samples of Chironomus plumosus L. (Diptera, Chironomidae) taken from waterbodies of various types in Bryansk region (Russia) and Gomel region (Belarus). Karyotypes of specimens taken from stream pools of the Volga were used as reference samples. The populations of Bryansk and Gomel regions (except for a population of Lake Strativa in Starodubskii district, Bryansk region) exhibit broad structural variation, including somatic mosaicism for morphotypes of the salivary gland chromosome set, decondensation of telomeric sites, and the presence of small structural changes, as opposed to populations of Saratov region. As compared with Saratov and Bryansk regions, the Balbiani ring in the B-arm of chromosome I is repressed in populations of Gomel region. It is concluded that the chromosome set of Ch. plumosus in a range of waterbodies of Bryansk and Gomel regions is unstable.

Revisiting regional flood frequency analysis in Slovakia: the region-of-influence method vs. traditional regional approaches

Science.gov (United States)

Gaál, Ladislav; Kohnová, Silvia; Szolgay, Ján.

2010-05-01

During the last 10-15 years, the Slovak hydrologists and water resources managers have been devoting considerable efforts to develop statistical tools for modelling probabilities of flood occurrence in a regional context. Initially, these models followed concepts to regional flood frequency analysis that were based on fixed regions, later the Hosking and Wallis's (HW; 1997) theory was adopted and modified. Nevertheless, it turned out to be that delineating homogeneous regions using these approaches is not a straightforward task, mostly due to the complex orography of the country. In this poster we aim at revisiting flood frequency analyses so far accomplished for Slovakia by adopting one of the pooling approaches, i.e. the region-of-influence (ROI) approach (Burn, 1990). In the ROI approach, unique pooling groups of similar sites are defined for each site under study. The similarity of sites is defined through Euclidean distance in the space of site attributes that had also proved applicability in former cluster analyses: catchment area, afforested area, hydrogeological catchment index and the mean annual precipitation. The homogeneity of the proposed pooling groups is evaluated by the built-in homogeneity test by Lu and Stedinger (1992). Two alternatives of the ROI approach are examined: in the first one the target size of the pooling groups is adjusted to the target return period T of the estimated flood quantiles, while in the other one, the target size is fixed, regardless of the target T. The statistical models of the ROI approach are inter-compared by the conventional regionalization approach based on the HW methodology where the parameters of flood frequency distributions were derived by means of L-moment statistics and a regional formula for the estimation of the index flood was derived by multiple regression methods using physiographic and climatic catchment characteristics. The inter-comparison of different frequency models is evaluated by means of the

The use of freely diffusable inert radioactive gas as a washout indicator to measure regional cerebral blood flow has become a standardized kinetic procedure in many laboratories. Recent investigations with this technique have led us to conclude that we can reliably distinguish regional flow with perfusion against regional flow without perfusion from the early portion of the curve. Based on a detailed study of the early curve kinetics in patients with and without cerebral vascular disease we have defined the sampling duration necessary for application of the Anger gamma camera imaging process to regional changes in cerebral radioactivity. Using a standard camera and a small computer, a procedure has been developed and based upon entire field to determine the time of maximum height followed by analysis of the data in a matrix. This will permit a contour plot presentation of calculated regional cerebral blood flow in millilitres per 100 grams perfused brain per minute. In addition, we propose to augment this data by the display of regional non-perfusion blood flow versus regional cerebral flow with perfusion. Preliminary investigation on sampling duration, and Compton scattering were prerequisite to clinical scintigraphy of regional cerebral blood flow. In addition, the method of interface for the conventional Anger gamma camera to digital computers used in this procedure are discussed. Applications to further assess regional cerebral dynamics by scintigraphy are presented. (author)

Latin America Region: Between Dependence and Autonomy in Regional Processes

2017-01-01

Full Text Available The space called Latin America has a particular history marked by centuries of colonialism and coloniality. The latter concept implies that the basic structure of the colonial system has not changed even though formal independence has been achieved. For this reason, the subcontinent has fluctuated between dependence and the quest for autonomy. These successive cycles have manifested themselves both in the internal configurations and in the regional schemes that have been undertaken. This paper analyzes the construction and evolution of the idea of a region: Latin America and the Caribbean. To that end it examines the concepts of region, regionalism, what Latin America and the Caribbean implies, and what are the transformations in these ideas that have emerged from the regional configurations of the Union of South American Nations (UNASUR and the Community of Latin American and Caribbean States (CELAC as plural organisms with broad objectives.

Body region dissatisfaction predicts attention to body regions on other women.

Lykins, Amy D; Ferris, Tamara; Graham, Cynthia A

2014-09-01

The proliferation of "idealized" (i.e., very thin and attractive) women in the media has contributed to increasing rates of body dissatisfaction among women. However, it remains relatively unknown how women attend to these images: does dissatisfaction predict greater or lesser attention to these body regions on others? Fifty healthy women (mean age=21.8 years) viewed images of idealized and plus-size models; an eye-tracker recorded visual attention. Participants also completed measures of satisfaction for specific body regions, which were then used as predictors of visual attention to these regions on models. Consistent with an avoidance-type process, lower levels of satisfaction with the two regions of greatest reported concern (mid, lower torso) predicted less attention to these regions; greater satisfaction predicted more attention to these regions. While this visual attention bias may aid in preserving self-esteem when viewing idealized others, it may preclude the opportunity for comparisons that could improve self-esteem.

By the methods of in situ investigation and regional ecological planning, the present ecological environment, ecosystem vulnerability, and ecological environment sensitivity in "Ji Triangle" Region were analyzed, and the ecological network of the study area was constructed. According to the ecological resources abundance degree, ecological recovery, farmland windbreak system, environmental carrying capacity, forestry foundation, and ecosystem integrity, the study area was classified into three regional ecological function ecosystems, i. e., east low hill ecosystem, middle plain ecosystem, and west plain wetland ecosystem. On the basis of marking regional ecological nodes, the regional ecological corridor (Haerbin-Dalian regional axis, Changchun-Jilin, Changchun-Songyuan, Jilin-Songyuan, Jilin-Siping, and Songyuan-Siping transportation corridor) and regional ecological network (one ring, three links, and three belts) were constructed. Taking the requests of regional ecological security into consideration, the ecological environment security system of "Ji Triangle" Region, including regional ecological conservation district, regional ecological restored district, and regional ecological management district, was built.

Local actors at community level often thrive for energy autarky to decrease the dependence on imported energy resources. We assess the potentials and trade-offs between benefits and costs of increasing levels of energy autarky for a small rural region of around 21,000 inhabitants in Austria. We use a novel modeling approach which couples a regional energy system model with a regional land use optimization model. We have collected and processed data on the spatial distribution of energy demand and potentials of biomass, photovoltaics and solar thermal resources. The impacts of increasing biomass production on the agricultural sector are assessed with a land-use optimization model that allows deriving regional biomass supply curves. An energy system model is subsequently applied to find the least cost solution for supplying the region with energy resources. Model results indicate that fossil fuel use for heating can be replaced at low costs by increasing forestry and agricultural biomass production. However, autarky in the electricity and the heating sector would significantly increase biomass production and require a full use of the potentials of photovoltaics on roof tops. Attaining energy autarky implies high costs to consumers and a decline in the local production of food and feed. - Highlights: ► Energy autarky strong vision for many regional actors. ► Assessment of consequences of energy autarky for a rural region in Austria. ► Novel modeling approach coupling energy system model with land use model. ► Power and heat autarky causes high costs and decline in regional food and feed production. ► Heat autarky achievable at lower costs by utilizing regional forestry and agricultural biomass.

Cluster headache (CH) has been associated with certain personality traits and lifestyle features, but there are few studies assessing personality profiles in CH. We aimed to analyze personality traits in patients with CH, and to compare them with those found in migraine. We included all consecutive patients with CH attending 5 outpatient offices between January and December 2013. Personality traits were evaluated using the Salamanca screening test, a validated inventory assessing 11 personality traits grouped in 3 clusters. We analyzed the test results in this population, and compared them with those of a migraine population previously assessed with the same test. Eighty patients with CH (75 men, 5 women; mean age, 43.2 ± 9.9 years) were recruited. The reference population consisted of 164 migraine patients (30 men, 134 women; mean age 36.4 ± 12.7 years). In CH patients, the most frequent personality traits were anancastic (52.5 %), anxious (47.5 %), histrionic (45 %), schizoid (42.5 %), impulsive (32.5 %) and paranoid (30 %). When compared to migraine patients, paranoid (p traits (p = 0.007; χ2 test) were significantly more prevalent in CH patients. In logistic regression analysis the paranoid trait was significantly associated with CH (p = 0.001; OR: 3.27, 95 % CI [1.66-6.43]). According to the Salamanca screening test, personality traits included in cluster A (odd or eccentric disorders) are more prevalent in CH patients than in a population of migraineurs. Larger studies are needed to determine whether certain personality traits are related to CH.

The risk of developing cancer is regulated by genetic variants, including polymorphisms. Characterizing such variants may help in developing protocols for personalized medicine. Adrenomedullin is a regulatory peptide involved in cancer promotion and progression. Carriers of a single nucleotide polymorphism (SNP) in the proximity of the adrenomedullin gene have lower levels of circulating peptide. The aim of the present work was to investigate whether carriers of this SNP (rs4910118) are protected against cancer. This was a retrospective study. DNA samples were obtained from the Carlos III DNA National Bank (University of Salamanca, Salamanca, Spain). Samples represent a variety of donors and patients from Spain. DNA from patients with breast cancer (n = 238), patients with lung cancer (n = 348), patients with cardiac insufficiency (n = 474), and healthy donors of advanced age (n = 500) was used. All samples were genotyped using double-mismatch PCR, and confirmation was achieved by direct sequencing. The minor allele frequency was calculated in all groups. The Pearson χ(2) was used to compare SNP frequencies. Of 1560 samples, 14 had the minor allele, with a minor allele frequency in healthy donors of 0.90%. Patients with cancer had a statistically significantly lower frequency than healthy donors (odds ratio = 0.216, 95% confidence interval = 0.048-0.967, P = .028). Carriers of the minor allele have a 4.6-fold lower risk of developing cancer than homozygotes for the major allele. Knowledge of the rs4910118 genotype may be useful for stratifying patients in clinical trials and for designing prevention strategies.

The NRC Office of Inspection and Enforcement (IE) has elected to evaluate the effectiveness and efficiency of its existing regional boundary alignment because of the anticipated future growth of nuclear power generating facilities and corresponding inspection requirements. This report documents a management study designed to identify, analyze, and evaluate alternative regional boundary configurations for the NRC/IE regions. Eight boundary configurations were chosen for evaluation. These configurations offered alternatives ranging from two to ten regions, and some included the concepts of subregional or satellite offices. Each alternative configuration was evaluated according to three major criteria: project workload, cost, and office location. Each major criterion included elements such as management control, program uniformity, disruption, costs, and coordination with other agencies. The conclusion reached was that regional configurations with regions of equal and relatively large workloads, combined with the concepts of subregional or satellite offices, may offer a significant benefit to the Office of Inspection and Enforcement and the Commission and are worthy of further study. A phased implementation plan, which is suitable to some configurations, may help mitigate the disruption created by realignment

Full Text Available Regional development policy is a policy of investment for economic development by supporting competitiveness, increasing the standards of living, improving the quality of life, creating new jobs. Regions and regional development policy occupies in recent decades an increasingly important position in the list of the economic and social factors being found on the agendas of governments, both central and local authorities, of political groups and civil society. Regional development and regional development policy in Romania are present both in the economic reform and in social one. Development Regions from Romania are set up in 1998 by Law number 151 and supported by their own institutional framework. The applicability of regional development in Romania must take into account the fundamental elements of the possibilities of Regional Development, meaning the major indicators of reference for measuring the level of disparities, GDP per capita and unemployment.
