Continuous Global Positioning System (cGPS) time series in Guerrero, Mexico, reveal the widespread existence of large Slow Slip Events (SSEs) at the boundary between the Cocos and North American plates. The existence of these SSEs asks the question of how seismic and aseismic slips complement each other in subduction zones. We examined the last three SSEs that occurred in 2001/2002, 2006 and 2009/2010, and their impact on the strain accumulation along the Guerrero subduction margin. We use continuous cGPS time series and InSAR images to evaluate the surface displacement during SSEs and inter-SSE periods. The slip distributions on the plate interface associated with each SSE, as well as the inter-SSE (short-term) coupling rates are evaluated by inverting these surface displacements. Our results reveal that the three analyzed SSEs have equivalent moment magnitudes of around 7.5 and their lateral extension is variable.The slip distributions for the three SSEs show that in the Guerrero gap area, the slow slip occurs at shallower depth (updip limit around 15-20 km) than in surrounding regions. The InSAR data provide additional information for the 2006 SSE. The joint inversion of InSAR and cGPS data confirms the lateral variation of the slip distribution along the trench, with shallower slip in the Guerrero seismic gap, west of Acapulco, and deeper slip further east. Inversion of inter-SSE displacement rates reveal that during the inter-SSE time intervals, the interplate coupling is high in the area where the slow slip subsequently occurs. Over a 12 year period, corresponding to three cycles of SSEs, our results reveal that the accumulated slip deficit in the Guerrero gap area is only ¼ of the slip deficit accumulated on both sides of the gap. Moreover, the regions of large slip deficit coincide with the rupture areas of recent large earthquakes. We conclude that the SSEs account for a major portion of the overall moment release budget in the Guerrero gap. If large

Insights into the causal relationship between slow slip and tectonic tremor in Guerrero, Mexico

Villafuerte, Carlos; Cruz-Atienza, Víctor M.

2017-08-01

Similar to other subduction zones, tectonic tremors (TTs) and slow-slip events (SSEs) take place in the deep segment of the plate interface in Guerrero, Mexico. However, their spatial correlation in this region is not as clear as the episodic tremor and slip observed in Cascadia and Japan. In this study we provide insights into the causal relationship between TTs and SSEs in Guerrero by analyzing the evolution of the deformation fields induced by the long-term 2006 SSE together with new locations of TTs and low-frequency earthquakes (LFEs). Unlike previous studies we find that the SSE slip rate modulates the TT and LFE activity in the whole tremor region. This means that the causal relationship between the SSE and the TT activity directly depends on the stressing rate history of the tremor asperities that is modulated by the surrounding slip rate. We estimated that the frictional strength of the asperities producing tremor downdip in the sweet spot is around 3.2 kPa, which is 2.3 times smaller than the corresponding value updip in the transient zone, partly explaining the overwhelming tremor activity of the sweet spot despite that the slow slip there is smaller. Based on the LFE occurrence-rate history during the interlong-term SSE period, we determined that the short-term SSEs in Guerrero take place further downdip (about 35 km) than previously estimated, with maximum slip of about 8 mm in the sweet spot. This new model features a continuum of slow slip extending across the entire tremor region of Guerrero.

Full Text Available Uma alimentação adequada é necessária para suprir a demanda energética requerida pelo exercício tanto para esportistas como para atletas. Porém, muito mais do que o rendimento no esporte, o conhecimento sobre nutrição para prevenção de doenças é fundamental para ambas as populações. Muitas intervenções centradas na educação nutricional têm sido conduzidas com o intuito de aumentar o conhecimento nutricional da população e, conseqüentemente, melhorar seus hábitos alimentares. O presente estudo tem por objetivo avaliar o conhecimento nutricional de atletas profissionais e amadores de atletismo por meio da aplicação de uma escala previamente validada no Brasil. A amostra foi composta por 26 atletas profissionais e 41 atletas amadores de atletismo de diversas modalidades em fase de treinamento contínuo. Os resultados mostraram que atletas profissionais e amadores de atletismo apresentaram, de modo geral, conhecimento nutricional moderado, sendo que este último apresentou pontuação significativamente maior que o grupo de profissionais, fato este associado ao maior grau de instrução/escolaridade. Conclui-se que atletas profissionais de atletismo apresentam conhecimento nutricional inferior a amadores, o que pode ser atribuído, em parte, ao fato destes vivenciarem a ciência da nutrição com o objetivo primário de rendimento esportivo.

Medicinal plants have been used for centuries for the empirical treatment of many diseases. This study documented the use of plant species in traditional medicine in the municipality of Xalpatlahuac, Guerrero, México. Direct interviews were performed with inhabitants from Xalpatlahuac. The interviews were analyzed with two quantitative tools: (a) the informant consensus factor (ICF) that estimates the level of agreement about which medicinal plants may be used for each category and (b) the relative importance (RI) that determines the extent of potential utilization of each species. A total of 67 plant species with medicinal purposes, belonging to 36 families and used to treat 55 illnesses and 3 cultural filiations were reported by interviewees. Nineteen mixtures with medicinal plants were reported by the interviewers. Mentha piperita was the most used plant for combinations (4 mixtures). The results of the ICF showed that diseases of the respiratory and digestive systems had the greatest agreement. The most versatile species according to their RI are Marrubium vulgare, Mimosa albida and Psidium guajava.. This study demonstrates that plant species play an important role in healing practices and magical-religious rituals among inhabitants from Xalpatlahuac, Guerrero, Mexico. Furthermore, pharmacological, phytochemical and toxicological studies with medicinal flora, including mixtures, are required for the experimental validation of their traditional uses.

Brittle and ductile friction modeling of triggered tremor in Guerrero, Mexico

Zhang, Y.; Daub, E. G.; Wu, C.

2017-12-01

Low frequency earthquakes (LFEs), which make up the highest amplitude portions of non-volcanic tremor, are mostly found along subduction zones at a depth of 30-40km which is typically within the brittle-ductile transition zone. Previous studies in Guerrero, Mexico demonstrated a relationship between the bursts of LFEs and the contact states of fault interfaces, and LFEs that triggered by different mechanisms were observed along different parts of the subduction zone. To better understand the physics of fault interfaces at depth, especially the influence of contact states of these asperities, we use a brittle-ductile friction model to simulate the occurrence of LFE families from a model of frictional failure and slip. This model takes the stress state, slip rate, perturbation force, fault area, and brittle-ductile frictional contact characteristics and simulates the times and amplitudes of LFE occurrence for a single family. We examine both spontaneous and triggered tremor occurrence by including stresses due to external seismic waves, such as the 2010 Maule Earthquake, which triggered tremor and slow slip on the Guerrero section of the subduction zone. By comparing our model output with detailed observations of LFE occurrence, we can determine valuable constraints on the frictional properties of subduction zones at depth.

Empacho is one of the main traditional illnesses recognized by the inhabitants of the coast of Oaxaca and Guerrero. This is a qualitative study based on the in depth analysis of the interviews held with fourteen informants: mothers, grand-mothers, physicians and folk healers or therapists specialists among others, from the localities of Charco Redondo, El Azufre and El Ciruelo in Oaxaca; Las Perias, La Fortuna and the municipal head of Copala in Guerrero. Our results show that empacho is a childhood endemic illness that can be differentiated from other gastrointestinal diseases. The care for this illness starts at home, where the mother alone or with the support of other women who are part of her social network, decide what steps to take for its care. Empacho used to be and continues to be a major health problem for social groups mainly from the countryside because it is considered life threatening. Therefore, it should be considered among the main illness that affect especially babies and preschoolers. However, mothers refrain from talking about this disease and its treatment in order not to be scolded by their conventional doctor.

This study attempts to recount the history of the main hospitals of the port of Acapulco from colonial times until the end of the 20th century. The Augustine friars began hospital care at the end of the first part of the 16th century. Later, Bernardino Alvarez (1514?-1584), with the support of the Spanish crown, founded the first formal hospital in Acapulco called Hospital de Nuestra Señora de la Consolación (Our Lady of Consolation Hospital). During the 16th and 17th centuries, the sick were attended by friars, and by the end of the 19th century there were physicians and surgeons. From the end of the Independence War until the end of the 19th century, the port did not have any true hospital. The first degreed physicians and surgeons arrived and resided in Acapulco in 1920. In 1938, the Hospital Civil Morelos (Morelos Civil Hospital) began providing services. It was replaced by the Hospital General de Acapulco (General Hospital of Acapulco). At the fourth decade of the past century the Cruz Roja (Red Cross) was created. In 1957 the hospital services of the Instituto Mexicano del Seguro Social (IMSS, Mexican Institute of Social Security), which was founded in 1963, was inaugurated with the Unidad Medico/Social (Medical and Social Unit) of the IMSS in Acapulco. This began the journey of modernity in Acapulco. In 1992, Hospital Regional Vicente Guerrero (Regional Hospital Vicente Guerrero) of the IMSS, initiated its services. In 1960, medical services for civil workers and their families were housed in the Hospital Civil Morelos (Morelos Civil Hospital). Shortly afterwards, the Instituto de Seguridad y Servicios Sociales para los Trabajadores del Estado (ISSSTE, Security and Social Services Institute for State Employees) had their own hospital. During the 20th century, Acapulco has added other hospital services to care for members of the navy and armed forces, as well as for those persons with financial resources for private care.

Coupled Flow and Geomechanics Modeling of Slow Earthquakes: Application to Slow Slip Events (SSE) in the Guerrero Gap, Mexico

Science.gov (United States)

Alves da Silva Junior, J.; Frank, W.; Castineira, D.; Jha, B.; Juanes, R.

2016-12-01

Three major cycles of slow slip events (SSE) have been reported since the early 2000s in the Guerrero gap, Mexico, on the boundary between the Cocos and North American plates. Analysis of teleseismic waveforms recorded on a dense temporary seismic network in the Guerrero gap have found low S-wave velocity and high Vp/Vs ratios at the depths corresponding to the sources of SSE, implying the possible presence of fluids and thus an active dewatering process that may result in near-lithostatic pore pressure at the plate interface. Here we use coupled flow and geomechanics analysis of the Guerrero gap to model transient changes in the stress field in the subduction zone as a result of pore pressure fluctuations and potential fluid flow along the subduction interface. Our computational modeling approach couples a multiphase flow simulator with a mechanical simulator using the unconditionally stable fixed stress scheme for the sequential solution of the two-way coupling between flow and geomechanics (Jha and Juanes, 2014). We assume quasi-static mechanical deformation and neglect the inertial term in the solid momentum balance equation—an approximation that is valid to model SSE assuming aseismic slip. We represent the subducting Cocos fault as a surface embedded in a three-dimensional medium, and use zero thickness interface elements to accurately model stick-slip behavior under dynamically evolving fluid pressure and fault strength. We employ the rate- and state-dependent friction model in the evolution of the coefficient of friction. We calibrate our model using two distinct datasets—GPS data and tremor catalogs in the area of Guerrero gap—and by separately constraining the rate of water production from a model of mineral hydration with depth. Our quantitative modeling approach furnishes a mechanistic understanding of the relationship between pore pressure evolution, stress transfer and tremor migration, and helps elucidate the origin of SSE in this area.

Full Text Available En este artículo se presenta una evaluación de las tendencias de la marginación en el estado de Guerrero durante el periodo 1995-2005. El análisis se realizó a partir de datos históricos de los Índices construidos por el Consejo Nacional de Población, obtenidos desde 1995, pero principalmente con los emanados tanto del XII Censo General de Población y Vivienda del 2000, como del II Conteo de Población y Vivienda 2005. Los resultados muestran que Guerrero, con el paso del tiempo, ha pasado a ser la entidad mexicana de más alta marginación entre las treinta y dos que conforman la República Mexicana. En términos del análisis del Índice de Marginación a nivel intra regional, se encuentra que de las siete regiones en que se divide Guerrero, en tres: Centro, Montaña y Costa Chica, donde vive 40 por ciento de la población estatal, se presenta una media de muy alto grado de marginación. En las otras tres regiones: Tierra Caliente, Costa Grande y Norte, donde se ubica 37 por ciento de los guerrerenses, su nivel de marginalidad es alto y sólo en la región Acapulco, donde se asienta un poco más de 23 por ciento de la población del estado, el grado de marginalidad es bajo. Tales resultados demuestran que 63 por ciento de la población, un poco más de 2 357 000 guerrerenses, viven en condiciones de alta y muy alta marginación, padeciendo carencias de servicios de salud, educación, vivienda digna y empleo.

Full Text Available Indigenous peoples of Guerrero show different tradeoffs in their ways of dealing with such adverse reality that afflicts them , first struggling to maintain the traditions and customs , using their customary community practices to maintain unity and confront the inhumane living conditions through what has been called community organization , considered part of the concept of social capital and the other institutions that do their thing trying to find solutions to this problem , however the methods collide and sometimes opposed. The community Assembly, the safety, the slaughter, the tequio are part of some of these practices, which despite maintained indigenous families living conditions have not improved substantially and increasingly is more noticeable migration in search of employment, in different scenarios. The majority indigenous population inhabiting the Amuzgos of Guerrero State, Mixtecos, Tlapanecos and Nahuas, looking each one with its own peculiarities, survive. Poverty, marginalization and physical-geographical conditions determine the circle of the dire living conditions of these indigenous people. As happened in 2013 with the tropical storm "Manuel", where we witnessed the way how adverse natural phenomena stick stronger to weaker.

In Mexico, organochlorine pesticides were used in public health and agriculture programs, causing chronic exposure to the population. Human breast milk samples were collected from 171 mothers who were residents from Guerrero, Mexico. Analysis was carried out by gas chromatography. Median concentrations (mg/kg on fat basis) for the following pesticides were: HCB, 0.009; β-HCH, 0.004; pp'DDE, 0.760; op'DDT, 0.016; pp'DDT, 0.045; and Σ-DDT, 0.833. These values are lower than in other States in Mexico, and in some countries where the use of these pesticides was banned more than 30 years ago. Differences were found in HCB, pp'DDE and pp'DDT concentrations in groups divided according to age (p pesticide levels in human milk is expected in a few years.

The coast of Guerrero Negro (Baja California) has been known for a long time by archaeologists for its shipwrecks. Archaeologists are recovering objects that come from sunken Spanish galleons in the colonial period, and reach the American coast in the frontier of the USA with Mexico. An enamelled metallic object was found next to the beach in Guerrero Negro. We have analysed the piece with proton induced X-ray emission (PIXE) and Rutherford backscattering (RBS) in an attempt to establish whether the object could come from one of the colonial shipwrecks and to valuate its cleaning process. Scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDS) have been also performed in three samples taken from the object in order to observe the heterogeneity of the material. The materials found revealed the presence of typical lead-glass enamels from with pigments such as cuprite (red), or lead-tin yellow used in colonial times. The metallic part consisted of brass. As for the cleaning process, the average efficiency considered as the weight% of chlorine removed, was of 83.4% for brass and 100% for enamels

Chikungunya fever (CHIK) generally causes temporary sick leave, affecting groups of productive age, which represents a significant economic impact from the labor point of view. The objective was to estimate costs of disability due to chikungunya in the Instituto Mexicano del Seguro Social (IMSS) in Guerrero, Mexico. Cost assessment of working population from IMSS in Guerrero who met the definition of case for CHIK and took sick leave, which was registered in the Original Disability Certificates (OCI, according to its initials in Spanish) processed from January to April, 2015. Paid sick days were multiplied by the current minimum wage of the municipality of Acapulco (geographical area A, general = $ 70.10: seventy pesos with 10 cents per day]). Of all the OCIs, 31.5% (38 271/12 062) met the criteria for CHIK with a total of 41 197 prescribed days and 14 941 paid sick days with an estimated cost of 2 397 393.40 pesos (two million, three hundred and ninety seven thousand, three hundred and ninety three dollars and forty cents). Sick leaves increase the costs in health systems. These costs increase as increases the number of days granted. The average number of days granted is consistent with the information published in different articles.

MATERIAL Y MÉTODOS: Estudio transversal hecho en 2004, sobre picaduras de alacrán durante el ciclo agrícola 2003, con encuesta a hogares en 14 comunidades del estado de Guerrero, seleccionadas de forma aleatoria. Se obtuvieron frecuencias simples y análisis bivariado para identificar los factores asociados a la picadura de alacrán durante la pizca de maíz. Se estimó razón de momios para valorar la magnitud del efecto. RESULTADOS: La incidencia de picadura de alacrán fue de 15% (500/3 294 en 2003. El empleo de guantes se acompañó de menor riesgo de picaduras de alacrán en la mano (RM = 0.11; IC 95% 0.06-0.18. Usar sólo un guante podría evitar 133 picaduras por cada 1 000 campesinos que ahora no los utilizan. Los costos implicados por la picadura de alacrán sumaron 505.90 pesos (46 dólares estadounidenses. CONCLUSIONES: Es necesario promover el uso de guantes entre campesinos que viven en zonas con alta endemicidad de alacranes. Asimismo, extender la red de suministro de suero antialacrán a toda el área rural donde predominan especies muy tóxicas y orientar a los campesinos sobre la importancia de buscar atención oportuna en las unidades de salud.OBJECTIVE: Identify factors associated with scorpion stings among farm workers who pick corn in the Mexican state of Guerrero.

Full Text Available Studies about the permanence of natural protected areas are important, because they contribute to the promotion of the conservation target and to optimize economical and human resources of specific areas. Although there are no natural protected areas in Guerrero, it has suitable habitat for the jaguar, a common species used for planning and management of conservation areas. Since, there is actual evidence that environmental and anthropogenic variables may modify vertebrate species distribution with time, in this study we predicted the potential distribution of Panthera onca using MaxEnt for this Southeastern region. In addition, we made a projection considering the effect of a moderate climate change scenario, to evaluate the stability of the conservation area for a period of 24 years. Furthermore, we applied three threat scenarios for the actual prediction to define conservation priorities areas. In our results, we have found that 18 361Km2 (29% of this state has a permanent suitable habitat for jaguar conservation in the Sierra Madre del Sur and Pacific coast, with a possible loss of 2 000km2 in 24 years. This habitat is characterized by a 56% of temperate forest (mainly conifers and hardwoods 34%, and 35% of tropical deciduous forest. With the projections, the Southeastern region resulted with the higher anthropogenic impacts, while at the same time, an area of 7 900km2 in the Central-Western state was determined as a priority for conservation. To assure jaguar conservation, we propose the inclusion of this new conservation area, which is located in the Sierra Madre del Sur, with which we may potentially preserve other 250 species of threatened vertebrates. This way, the suggested habitat conservation may represent a local effort in Guerrero and will strengthen the biological corridor network for P. onca protection in Latin America.

The microbial mats of Guerrero Negro (GN), Baja California Sur, Mexico historically were considered a simple environment, dominated by cyanobacteria and sulfate-reducing bacteria. Culture-independent rRNA community profiling instead revealed these microbial mats as among the most phylogenetically diverse environments known. A preliminary molecular survey of the GN mat based on only ∼1500 small subunit rRNA gene sequences discovered several new phylum-level groups in the bacterial phylogenetic domain and many previously undetected lower-level taxa. We determined an additional ∼119,000 nearly full-length sequences and 28,000 >200 nucleotide 454 reads from a 10-layer depth profile of the GN mat. With this unprecedented coverage of long sequences from one environment, we confirm the mat is phylogenetically stratified, presumably corresponding to light and geochemical gradients throughout the depth of the mat. Previous shotgun metagenomic data from the same depth profile show the same stratified pattern and suggest that metagenome properties may be predictable from rRNA gene sequences. We verify previously identified novel lineages and identify new phylogenetic diversity at lower taxonomic levels, for example, thousands of operational taxonomic units at the family-genus levels differ considerably from known sequences. The new sequences populate parts of the bacterial phylogenetic tree that previously were poorly described, but indicate that any comprehensive survey of GN diversity has only begun. Finally, we show that taxonomic conclusions are generally congruent between Sanger and 454 sequencing technologies, with the taxonomic resolution achieved dependent on the abundance of reference sequences in the relevant region of the rRNA tree of life.

Full Text Available El Objetivo del trabajo fue identificar la motivación para el emprendimiento y los factores del éxito competitivo de los emprendedores de pequeños negocios que se ubican en la Montaña de Guerrero, México. Se aplicó un cuestionario con preguntas cerradas, con una escala de tipo Likert, con variables de los factores económicos, psicológicos, sociales y culturales para identificar diferencias de emprendimiento y del éxito competitivo. Estas diferencias fueron medidas con base en la importancia que el dueño le asignó a las acciones de desarrollo del negocio. Con la prueba de U de Mann-Whitney se evaluó estadísticamente si había diferencias en el éxito competitivo entre los municipios de Huamuxtitlán y Metlatónoc. Los resultados indicaron que la mayoría de los emprendedores son jóvenes y en su mayoría son mujeres, quienes inician la microempresa con ahorros propios y predomina en su operación la informalidad. El factor económico de motivación para emprender una microempresa o negocio fue la mejora en el ingreso. El principal factor psicológico fue la confianza en el éxito del negocio, siendo importante la motivación del o la conyugue. El factor social fue el desempleo y el factor espacial fue la buena ubicación del negocio. Al comparar entre municipios, se encontró diferencia estadística significativa entre ellos (p ≤ 0.001 para todos los factores evaluados. El análisis de regresión logística binaria indicó que las variables de mayor peso para la consolidación o éxito de las empresas de los emprendedores de la Montaña de Guerrero son la edad, la escolaridad y el lugar donde estén ubicados.

Full Text Available The infective larva of Litomosoides yutajensis Guerrero et al., 2003, a parasite of the bat Pteronotus parnellii, is described; it is distinct from congeneric infective larvae by the absence of caudal lappets. The life cycles of five other species of Litomosoides are known; three are parasites of rodents, one of a marsupial and one of a bat. As with these species, the experimental vector of L. yutajensis used was the macronyssid mite Ornithonyssus bacoti. In nature, the main vectors are probably other macronyssids but transmission by O. bacoti, with its large host-range, could account for the characteristic host-switchings in the evolution of Litomosoides. Unlike the murine model L. sigmodontis Chandler, 1931, L. yutajensis is devoid of the endosymbiontic bacteria Wolbachia and may be of great interest.

Full Text Available Hurricanes and other tropical storms are natural phenomena that attract the interest of people all over the world, especially when they affect coastal communities. Each year, especially during the hurricane season, it is common to read or see in the different media damage caused by tropical storms in several countries, especially in Latin America and Asia. In Mexico total economic losses associated with natural phenomena has been increasing. During the year 2000 were allocated 230 million US dollars for the reconstruction of the infrastructure affected by hydrometeorological phenomena, while in 2013 damage amounted to $ 4,476 million, peaking during 2010 were recorded when 7,208 million dollars in losses. On the other hand, the total of damage caused by natural phenomena, 92 % were associated with hydrometeorological phenomena, which include hurricanes and other phenomena (SEGOB, 2014. The aim of this paper is to analyze the impacts caused by disasters associated with the influence of hurricanes from a comparative perspective between two phenomena in particular, hurricane Pauline in 1997 and Manuel storm in 2013 events hydrometeorological which affected the Mexican state of Guerrero, but especially to the port of Acapulco. one of the main conclusions of this study refers to that no matter only the intensity of the natural phenomenon to generate damage on society, but the total of damages also refers to the contexts of vulnerability generated by a society with the course of the years.

Oswaldocruzia lamotheargumedoi n. sp., inhabiting the intestine of the cane toad, Rhinella marina (L.), in Laguna de Coyuca, Guerrero, México, is described here. The new species differs from 10 congeners infecting bufonid hosts because it has a type I bursa. In contrast, 7 of these species have type II bursa and 3 more a type III bursa. The species most similar to the species described herein is Oswaldocruzia pipiens Walton, 1929 . These 2 species share traits such as body size, bursa type, presence of cervical alae, and dorsal ray morphology. Nevertheless, both species can be distinguished based on the number of synlophe ridges at mid-body (54-56 for O. lamotheargumedoi vs. 45-48 for O. pipiens) and by the presence of a chitinous support in the long, and well developed, cervical alae of O. pipiens. In the new species, these structures are short, poorly developed, and lack chitinous support. Previous records of species of Oswaldocruzia in México include Oswaldocruzia subauricularis (Rudolphi, 1819) Travassos, 1917 in the Neotropical Realm and O. pipiens in the Nearctic.

Geomorphic indices and relative tectonic uplift in the Guerrero sector of the Mexican forearc

Directory of Open Access Journals (Sweden)

Krzysztof Gaidzik

2017-07-01

The results of the applied landscape analysis reveal considerable variations in relief, topography and geomorphic indices values along the Guerrero sector of the Mexican subduction zone. We argue that the reported differences are indicative of tectonic deformation and of variations in relative tectonic uplift along the studied forearc. A significant drop from central and eastern parts of the study area towards the west in values of RVA (from ∼500 to ∼300, SL (from ∼500 to ca. 400, maximum SL (from ∼1500–2500 to ∼1000 and ksn (from ∼150 to ∼100 denotes a decrease in relative tectonic uplift in the same direction. We suggest that applied geomorphic indices values and forearc topography are independent of climate and lithology. Actual mechanisms responsible for the observed variations and inferred changes in relative forearc tectonic uplift call for further studies that explain the physical processes that control the forearc along strike uplift variations and that determine the rates of uplift. The proposed methodology and results obtained through this study could prove useful to scientists who study the geomorphology of forearc regions and active subduction zones.

Estimamos densidades de 1 300 nidos/ha en la ladera y de 2 000 nidos/ha en la cima de la isla.

Los viajes de forrajeo más largos (5.78 ± 0.21 h y los buceos más profundos (5.52 ± 0.42 m en Morros El Potosí que en otras colonias, sugirieron que los bobos cafés requirieron aquí un mayor esfuerzo de forrajeo, quizás por estar en aguas más calientes, con menos recursos. Los bobos cafés hembra atendieron por más tiempo los nidos con huevos o con pollos que los machos. No hubo diferencias en el tiempo de presencia de los padres en el nido entre meses, lo que, aunado a la variación en la duración de los viajes de forrajeo entre meses, sugiere que hubo fluctuaciones de corta duración en la disponibilidad de alimento durante el periodo de estudio.We studied the breeding ecology of Brown Boobies (Sula leucogaster at Morros El Potosí, Guerrero, between January and June 2006.

Detections of pP and sP phase arrivals (the so-called depth phases) at teleseismic distance provide one of the best ways to estimate earthquake focal depth, as the P-pP and the P-sP delays are strongly dependent on the depth. Based on a new processing workflow and using a single seismic array at teleseismic distance, we can estimate the depth of clusters of small events down to magnitude Mb 3.5. Our method provides a direct view of the relative variations of the seismicity depth from an active area. This study focuses on the application of this new methodology to study the lateral variations of the Guerrero subduction zone (Mexico) using the Eielson seismic array in Alaska (USA). After denoising the signals, 1232 Mb 3.5 + events were detected, with clear P, pP, sP and PcP arrivals. A high-resolution view of the lateral variations of the depth of the seismicity of the Guerero-Oaxaca area is thus obtained. The seismicity is shown to be mainly clustered along the interface, coherently following the geometry of the plate as constrained by the receiver-function analysis along the Meso America Subduction Experiment profile. From this study, the hypothesis of tears on the western part of Guerrero and the eastern part of Oaxaca are strongly confirmed by dramatic lateral changes in the depth of the earthquake clusters. The presence of these two tears might explain the observed lateral variations in seismicity, which is correlated with the boundaries of the slow slip events.

Full Text Available Studies about the permanence of natural protected areas are important, because they contribute to the promotion of the conservation target and to optimize economical and human resources of specific areas. Although there are no natural protected areas in Guerrero, it has suitable habitat for the jaguar, a common species used for planning and management of conservation areas. Since, there is actual evidence that environmental and anthropogenic variables may modify vertebrate species distribution with time, in this study we predicted the potential distribution of Panthera onca using MaxEnt for this Southeastern region. In addition, we made a projection considering the effect of a moderate climate change scenario, to evaluate the stability of the conservation area for a period of 24 years. Furthermore, we applied three threat scenarios for the actual prediction to define conservation priorities areas. In our results, we have found that 18 361Km2 (29% of this state has a permanent suitable habitat for jaguar conservation in the Sierra Madre del Sur and Pacific coast, with a possible loss of 2 000km2 in 24 years. This habitat is characterized by a 56% of temperate forest (mainly conifers and hardwoods 34%, and 35% of tropical deciduous forest. With the projections, the Southeastern region resulted with the higher anthropogenic impacts, while at the same time, an area of 7 900km2 in the Central-Western state was determined as a priority for conservation. To assure jaguar conservation, we propose the inclusion of this new conservation area, which is located in the Sierra Madre del Sur, with which we may potentially preserve other 250 species of threatened vertebrates. This way, the suggested habitat conservation may represent a local effort in Guerrero and will strengthen the biological corridor network for P. onca protection in Latin America.

Full Text Available The mango crop is attacked by various pests, in Arcelia, Tierra Caliente, Guerrero, Mexico. Scale insects (Hemiptera and thrips (Thysanoptera were identified, the pesticides imidacloprid, spinosad, sulfur and mineral oil were tested against them, as well as their effect on fruit quality, using pest action thresholds. The thrips Frankliniella invasor appeared in the highest populations, but F. difficilis, F. occidentalis, F. fortissima, F. cephalica, Leptothrips macconnelli, L. bifurcatus and L. theobromae were also found. It was observed that mineral oil maintained the lowest populations and least damage in fruit; thrips species did not cause significant damage because they were seasonal pests that only occur when soft tissue is available in plants and once this tissue becomes unavailable populations diminish without the need of insecticides.  The mite Cisaberoptus kenyae was identified, which in high populations can cause crop damage; for its control sulfur yielded better results. The scale Milviscutulus mangiferae was present in very low populations. Treatment with mineral oil resulted in the highest quality fruits.

Full Text Available The records of an aftershock (M ~ 4 of a moderate size event (M = 5.9 which occurred along the subduction zone of Guerrero (Mexico, are used as empirical Green functions (EGF to determine the source characteristics of the mainshock and of its smaller size (M = 5.5 foreshock. The data consist of accelerograms recorded by the Guerrero Accelerograph Array, a high dynamic range strong motion array. The three events appear to be located close to each other at distances much smaller than the source to receiver distances. The fault mechanism of the mainshock is computed by non-linear inversion of P polarity readings and S wave polarizations determined at two near source stations. The foreshock and aftershock fault mechanisms are similar to that of the mainshock as inferred from long period data and shear wave polarization analysis. The maximum likelihood solution is well constrained, indicating a typical shallow dipping thrust fault mechanism, with the P-axis approximately oriented in a SSW direction. The source time functions (STFs of the mainshock and foreshock events are determined using a new method of deconvolution of the EGF records at three strong motion sites. In this method the STF of the large event is approximated by a superposition of pseudo triangular pulses whose parameters are determined by a non-linear inversion in frequency domain. The source time function of the mainshock shows the presence of two separate pulses, which can be related to multiple rupture episodes. The relative location of mainshock sub-events is done by using plots of isochrones computed from measurementes of the time delay between pulses on the STF records at each station. The first sub-event is located no more than 2.5-3 km away from the other along the fault strike. The STF retrieved from foreshock records shows single pulse waveforms. The computed STFs are used to estimate seismic moments, source radii and stress release of the events assuming a circular fault

Full Text Available Dormitator is among the most important fish genera in the Mexican Pacific coastal lagoon systems. In Tres Palos Lagoon, the Fat Sleeper Dormitator latifrons is one of the most significant species based on catch volume, although it is only consumed locally. Very little information exists on this species’ parasitofauna. Composition and temporal variation in the metazoan parasite community structure of Dormitator latifrons from Tres Palos Lagoon (99º47’ W, 16º48’ N, Guerrero, Mexico, were determined using seasonal samples taken between April 2000 and June 2002. Ten parasite species (55 817 individuals were recovered from 219 examined hosts. These species included eight helminths (Ascocotyle (Phagicola longa, Echinochasmus leopoldinae, Clinostomum complanatum, Pseudoacanthostomum panamense, Saccocoelioides lamothei, Parvitaenia cochlearii, Contracaecum sp. and Neoechinorhynchus golvani and two crustaceans (Argulus sp. and Ergasilus sp.. Five of the helminth species exhibited seasonal variation in their infection dynamics associated with environmental changes during the dry and rainy seasons.

O estudo teve como objetivo verificar se a variação aguda da CK e da CK MB reflete algum risco de desgaste acentuado para a musculatura esquelética e cardíaca, de atletas amadores, após o Ironman 70.3. A amostra foi composta por dez atletas voluntários, masculinos (idade= 34,0 ± 9,2 anos. A amostra de sangue venoso (2mL foi coletada antes e após o Ironman 70.3. Os voluntários completaram o percurso em 5h20min à 6h. A CK e a CK MB foram analisadas pelo método enzimático, usando reagentes Wienner lab, em um espectrofotômetro automático (Targa bt 3000. O teste não paramétrico de Wilcoxon indicou diferenças significativas (p <0,05 entre os períodos pré e pós competição nas variáveis estudadas. Os valores médios foram: CK= 112,23 ± 34,9U/L e 458,0 ± 204,9U/L (Δ%= 418,2; CK MB= 7,4 ± 2,6U/L e 10,8 ± 3,9U/L (Δ%= 153,3, respectivamente, para pré e pós. A variação relativa da CK MB em relação à CK, pré (6,9% e pós competição (2,5%, indicou que este não é um fator tão preocupante durante o exercício extenuante de longa duração, como o Ironman 70.3. Conclui-se que a concentração aguda de CK, logo após o término do exercício extenuante de longa duração, indicou desgaste da musculatura esquelética, porém considerado normal para atletas. Quanto à CK MB, o desgaste da musculatura cardíaca foi inexistente.

The aim of this study was to evaluate the genotoxic effect of pesticides in exfoliated buccal cells of workers occupationally exposed in Guerrero, Mexico, using the comet assay and the micronucleus test. The study compared 111 agricultural workers in three rural communities (Arcelia 62, Ajuchitlan 13, and Tlapehuala 36), with 60 non-exposed individuals. All the participants were males. The presence of DNA damage was investigated in the exfoliated buccal cells of study participants with the comet assay and the micronucleus (MN) test; comet tail length was evaluated in 100 nuclei and 3000 epithelial cells of each individual, respectively; other nuclear anomalies such as nuclear buds, karyolysis, karyorrhexis, and binucleate cells were also evaluated. Study results revealed that the tail migration of DNA and the frequency of MN increased significantly in the exposed group, which also showed nuclear anomalies associated with cytotoxic or genotoxic effect. No positive correlation was noted between exposure time and tail length and micronuclei frequencies. No significant effect on genetic damage was observed as a result of age, smoking, and alcohol consumption. The MN and comet assay in exfoliated buccal cells are useful and minimally invasive methods for monitoring genetic damage in individuals exposed to pesticides. This study provided valuable data for establishing the possible risk to human health associated with pesticide exposure.

En el caso particular del estado de Guerrero, después de un análisis de la información hidrometeorológica disponible, se observó que el recurso agua a nivel superficial es abundante, aunque cabe la duda si es aprovechado de manera correcta y completa. Al hacer una revisión detallada de la base de datos observados de aguas superficiales se encontró que entre 1980 y 2000 hubo una disminución dramática en las estaciones en operación, en aproximadamente la mitad, al mismo tiempo que se encontraron in-coincidencias en las mismas bases de datos que dan un error en su manejo de un 4 a 7%. Todo esto conlleva a la dificultad de formar las isolíneas de escurrimiento superficial que permitan mostrar la disponibilidad real del recurso hídrico, así como la consecuencia de elaborar una estrategia incorrecta de planeación de su uso en interés del desarrollo económico y político del estado.

Existió una gran variabilidad en la composición de la dieta de cada mes. Sin embargo, los crustáceos en conjunto dominaron la dieta de febrero a agosto de 1993. En 1994, los crustáceos sólo fueron dominantes en marzo y agosto. No se encontraron diferencias en la dieta de peces inmaduros, machos y hembras. La dieta del huachinango del Pacífico varía con el crecimiento, aunque siempre se encuentran los mismos grupos de alimento. En la fase adulta, en clases de longitud mayores a 261 mm LF, existe un cierto grado de especialización, ya que consumen más peces, principalmente engráulidos.In this paper we describe the feeding habits of the Red

Full Text Available The effects of sex, injuries, season and site on the growth of the spiny lobsters Panulirus gracilis, and P. inflatus, were studied through mark-recapture techniques in two sites with different ecological characteristics on the coast of Guerrero, México. Panulirus gracilis occurred in both sites, whereas P. inflatus occurred only in one site. All recaptured individuals were adults. Both species had similar intermolt periods, but P. gracilis had significantly higher growth rates (mm carapace length week -1 than P. inflatus as a result of a larger molt increment. Growth rates of males were higher than those of females in both species owing to larger molt increments and shorter intermolt periods in males. Injuries had no effect on growth rates in either species. Individuals of P. gracilis grew faster in site 1 than in site 2. Therefore, the effect of season on growth of P. gracilis was analyzed separately in each site. In site 2, growth rates of P. gracilis were similar in summer and in winter, whereas insite 1 both species had higher growth rates in winter than in summer. This could be due to spatial differences in processes related to changes in population density and food resources, which were documented in previous works. The overall results show that P. gracilis grows faster than P. inflatus, and that growth rates of both species are highly variable and are affected by environmental factors such as site and season, which should be taken into account when attempting to produce population growth curves for each species.Se analizaron, por medio de marcado-recaptura, los efectos del sexo, heridas, estación del año y localidad sobre el crecimiento de las langostas espinosas Panulirus gracilis Streets, 1871, y Panulirus inflatus (Bouvier, 1895 en dos localidades con diferentes características ecológicas en la costa de Guerrero, México.

In this study we analyze the tremors triggered in Guerrero region (Mexico) by the 2010 magnitude 8.8 Chilean Earthquake using mini-seismic array data from the French-Mexican G-GAP project and broadband data from the Servicio Sismologico Nacional of Mexico. The strong dynamic shaking by the earthquake produced the first observed triggered non-volcanic tremors (NVT) in Mexico so far with at least 3 different types of tremors at different time scales. There was a slow slip event (SSE) occurring at the time of the earthquake, which may have increased the probability of tremor triggering in the region. The first type of observed triggered tremors occurred during the S waves, Love waves and Rayleigh waves as already reported in other subductions zones and continental faults (Miyazawa and Mori, 2005, 2006; Rubinstein et al., 2007; Gomberg et al., 2008; Peng et al, 2009…). The greatest amount of energy and duration accompanies the long-period Rayleigh waves, with smaller bursts during the S and Love waves. For this particular tremor we observed the dispersion of Rayleigh waves in the envelopes of triggered tremors, which indicates a very strong modulation of the source by the passing surface wave. An unexpected short-term tremor occurred approximately one hour later of the arrival of the surface waves on the coastal stations. The NVT has only been previously observed at distances > 100 km inland. It also has a shorter frequency range (3-6 Hz) than other NVT (1-10 Hz) observed in the region. Finally, we observed a significant increase of so-called ambient tremor activity with higher intensity than all triggered NVT during the days after the earthquake. This study adds new types of tremors to the lexicon of triggered NVT observed in the world.

Detailed Tremor Migration Styles in Guerrero, Mexico Imaged with Cross-station Cross-correlations

Tremor occurred downdip of the area that slipped the most during the 2006 slow slip event (SSE) in Guerrero, Mexico, as opposed to Cascadia, where tremor locations and rupture zones of SSEs largely overlap. Here we obtain high resolution tremor locations by applying cross-station cross-correlations [Armbruster et al., 2014] to seismic data from the Meso-America Subduction Experiment deployment. A few 3-station detectors are adopted to capture detailed deformation styles in the tremor "transient zone" and the downdip "sweet spot" as defined in Frank et al., 2014. Similar to Cascadia, tremor activities in our study region were comprised mostly of short tremor bursts lasting minutes to hours. Many of these bursts show clear migration patterns with propagation velocities of hundreds of km/day, comparable to those in Cascadia. However, the propagation of the main tremor front was often not in a simple unilateral fashion. Before the 2006 SSE, we observe 4 large tremor episodes during which both the transient zone and the sweet spot participated, consistent with previous findings [Frank et al., 2014]. The transient zone usually became active a few days after the sweet spot. We find many along-dip migrations with recurrence intervals of about a half day within a region about 10 km along strike and 35 km along dip in the sweet spot, suggesting possible tidal modulation, after the main front moved beyond this region. These migrations appear not to originate at the main front, in contrast to tremor migrations from a few km to tens of km across observed in Cascadia [Rubin and Armbruster, 2013; Peng et al., 2015; Peng and Rubin, submitted], but possibly similar to Shikoku, Japan [Shelly et al., 2007]. We do not observe obvious half-day periodicity for the migrations farther downdip within the sweet spot. During the SSE, the recurrence interval of tremor episodes decreased significantly in both the transient zone and the sweet spot, with that of the former being much shorter

Full Text Available Los manglares son un recurso forestal de gran importancia en los humedales, tanto por su diversidad y estructura maderable como por los beneficios ambientales y socioeconómicos que representan. Su composición depende de factores ambientales, condiciones edáficas, acción antrópica y de la capacidad de interrelacionarse entre sí para compartir un espacio. En el estado de Guerrero existen solo registros que indican áreas de distribución de bosques de manglar y descripción de especies. El objetivo fue conocer la importancia ecológica del manglar adjunto a las comunidades de El Carrizal y Playa Azul, municipio Coyuca de Benítez, Guerreo, a través de la obtención de su densidad y abundancia relativa, diversidad y volumen maderable.

Full Text Available Invasive Pterygoplichthys disjunctivus (Weber, 1991 (synonymy: Liposarcus multiradiatus armored catfish were first reported in Mexico in 1995 and have spread successfully in several aquatic ecosystems. In Adolfo López Mateos El Infiernillo Reservoir, Michoacán - Guerrero, the population of this armored catfish is growing substantially because natural predators are not present and exploitation by humans does not occur. Over a complete annual cycle, we studied the following population parameters: weight, total and standard length, the relationship of weight to total length, the hepatosomatic (HSI and gonadosomatic (GSI indices, total fecundity (TF and relative fecundity (RF. The average total (TL and standard lengths (SL were 248 ± 37.5 and 188 ± 30.7 mm, respectively, and the average weight (W was 135.3± 66.8 g. The largest fish reported was 520 mm in TL and weighed 1 280 g. The species showed an extended reproductive season from May to November, as indicated by the GSI, TF and RF. The strongest reproductive peak occurred from July through October. During the annual cycle, the highest monthly average fecundity was 2 447 eggs, and the average relative fecundity was 12.6 eggs per g of fish (August and September. This information will be crucial for calculating the current biomass and future growth of the population. The calculation of these results could provide a basis for the exploitation of this resource for human consumption and animal feeds.La especie invasiva "bagre armado" P. disjunctivus (Weber 1991 (sinonimia de Liposarcus multuradiatus fue registrada por primera vez en México en 1995; en diversos sistemas acuáticos se ha distribuido exitosamente.

In the Mexican state of Guerrero, some households place fish in water storage containers to prevent the development of mosquito larvae. Studies have shown that larvivorous fish reduce larva count in household water containers, but there is a lack of evidence about whether the use of fish is associated with a reduction in dengue virus infection. We used data from the follow up survey of the Camino Verde cluster randomised controlled trial of community mobilisation to reduce dengue risk to study this association. The survey in 2012, among 90 clusters in the three coastal regions of Guerrero State, included a questionnaire to 10,864 households about socio-demographic factors and self-reported cases of dengue illness in the previous year. Paired saliva samples provided serological evidence of recent dengue infection among 4856 children aged 3-9 years. An entomological survey in the same households looked for larvae and pupae of Aedes aegypti and recorded presence of fish and temephos in water containers. We examined associations with the two outcomes of recent dengue infection and reported dengue illness in bivariate analysis and then multivariate analysis using generalized linear mixed modelling. Some 17% (1730/10,111) of households had fish in their water containers. The presence of fish was associated with lower levels of recent dengue virus infection in children aged 3-9 years (OR 0.64; 95% CI 0.45-0.91), as was living in a rural area (OR 0.57; 95% CI 0.45-0.71), and being aged 3-5 years (OR 0.65; 95% CI 0.51-0.83). Factors associated with lower likelihood of self-reported dengue illness were: the presence of fish (OR 0.79; 95% CI 0.64-0.97), and living in a rural area (OR 0.74; 95% CI 0.65-0.84). Factors associated with higher likelihood of self-reported dengue illness were: higher education level of the household head (OR 1.28; 95% CI 1.07-1.52), living in a household with five people or less (OR 1.33; 95% CI 1.16-1.52) and household use of insecticide anti

Full Text Available The goal of this study was to use environmental sequencing of 16S rRNA and bop genes to compare the diversity of planktonic bacteria and archaea across ponds with increasing salinity in the Exportadora de Sal (ESSA evaporative saltern in Guerrero Negro, Baja CA S., Mexico. We hypothesized that diverse communities of heterotrophic bacteria and archaea would be found in the ESSA ponds, but that bacterial diversity would decrease relative to archaea at the highest salinities. Archaeal 16S rRNA diversity was higher in Ponds 11 and 12 (370 & 380 g l-1 total salts respectively compared to Pond 9 (180 g l-1 total salts. Both Pond 11 and 12 communities had high representation (47 and 45% of clones respectively by Haloquadratum walsbyi-like (99% similarity lineages. The archaeal community in Pond 9 was dominated (79% by a single uncultured phylotype with 99% similarity to sequences recovered from the Sfax saltern in Tunisia. This pattern was mirrored in bop gene diversity with greater numbers of highly supported phylotypes including many Haloquadratum-like sequences from the two highest salinity ponds. In Pond 9, most bop sequences, were not closely related to sequences in databases. Bacterial 16S rRNA diversity was higher than archaeal in both Pond 9 and Pond 12 samples, but not Pond 11, where a non-Salinibacter lineage within the Bacteroidetes >98% similar to environmental clones recovered from Lake Tuz in Turkey and a saltern in Chula Vista, CA was most abundant (69% of community. This OTU was also the most abundant in Pond 12, but only represented 14% of clones in the more diverse pond. The most abundant OTU in Pond 9 (33% of community was 99% similar to an uncultured gammaproteobacterial clone from the Salton Sea. Results suggest that the communities of saltern bacteria and archaea vary even in ponds with similar salinity and further investigation into the ecology of diverse, uncultured halophile communities is warranted.

La comunidad se caracterizó por un número mayor de parásitos generalistas y pocos especialistas de cíclidos, además por ser pobre en especies. De las 5 especies comunes dentro de la comunidad, 4 presentaron variación temporal en su dinámica de infección a lo largo del tiempo, la cual fue asociada con cambios ambientales generados durante las temporadas de secas y lluvias. La variación en la dinámica de infección de las especies comunes fue capaz de generar cambios en la estructura, tanto en el nivel de componente como en el de infracomunidad; sin embargo, no se observó un patrón claro, lo que indica que la comunidad puede ser poco predecible, como se sugiere para otras comunidades de parásitos de peces dulceacuícolas.We analyzed metazoan parasite community composition in the three-spot cichlid Cichlasoma trimaculatum using seasonal samples taken between April 2000 and November 2002 from the Tres Palos Lagoon, Guerrero, Mexico.

The composition and species richness in helminth communities of two species of heron, Ardea alba and Nyctanassa violacea, in two coastal lagoons from Guerrero, Mexico were examined. Nineteen species of helminth (7,804 individuals) were identified in 43 adult birds: 15 digeneans, 1 acanthocephalan, 1 cestode, and 2 nematodes. Eight species co-occurred in herons of both species and lagoons. The prevalence values of seven species and the mean abundance of five species varied significantly between species of birds and between lagoons. The heterophyid, Ascocotyle (Phagicola) longa, was the helminth numerically dominant in the helminth community of A. alba in both lagoons, while the cestode, Parvitaenia cochlearii, dominated the community of N. violacea. At the component community level, species richness varied significantly: 10 species in A. alba from Coyuca to 16 in N. violacea (Tres Palos). All of the birds examined were infected with helminth parasites: three to seven species per host in A. alba from Coyuca, and two to eight species in A. alba and N. violacea from Tres Palos. The results indicate that even though species composition was similar between both species of heron, the structure of their communities was not the same. Differences in the feeding behavior of the birds (day/night habits), as well as local differences in the abundance of species of fish, and infection levels of helminths in each lagoon are suggested as being responsible for the variations registered in the structure of the helminth communities.

Hypersaline environments have been significant reservoirs for the long-term evolution of specifically adapted microorganisms. Characterized to have higher salt concentrations (up to 35 g/L), they are worldwide distributed and have a commercial significance. Exportadora de Sal, Guerrero Negro, Mexico has a multipond salterns system designed to harvest common salt (NaCl) from sea water. To achieve this purpose, sea water is pumped through a set of shallow ponds where water evaporates and salts concentrate. Sequential precipitation of CaCO3, CaSO4 2H2O and NaCl occurs in a mineral formations call it evaporites. In the interior of those gypsum-encrusted and halite-encrusted minerals, communities of extremely salt-loving archaea prosper. Previous studies have showed the influence of Haloarchaeal cells in the formation of larger fluid inclusions than crystals formed in sterile salt solutions. S-layer envelopes and cells of Haloarcula strain SP8807 contributed to the nucleation of new crystals of NaCl. Given the significance of the scope in phylogenetic archaeal diversity research, this study had a polyphasic approach. SEM micrographs from a 21- 31% (w/v) gradient salt multipond system evaporites, gave an insight profile of the extreme halophilic archaeal communities thriving in the surface of the gypsum and halite evaporites. Halite crystals were form after 21 days of incubation in solid medium with archaeal cells. Both culture and non-culture dependent methods, Nested-PCR-DGGE analysis and sequencing of 16S rDNA amplified fragment genes from environmental samples and isolated strains were used for this purpose. We isolate three strains from Pond 9 (21.07% total salt concentration) and one strain from Cristallizer 20 (25.15% total salt concentration). 16S rDNA signaling gave 99% of similarity with Halogeometricum borinquense, sequence AF002984, two other strains were 99% of similarity with Halobacterium salinarum, sequence AJ496185 these strains shown different colony

Screening of polyhydroxyalkanoate-producing bacteria and PhaC-encoding genes in two hypersaline microbial mats from Guerrero Negro, Baja California Sur, Mexico

Full Text Available Hypersaline microbial mats develop through seasonal and diel fluctuations, as well as under several physicochemical variables. Hence, resident microorganisms commonly employ strategies such as the synthesis of polyhydroxyalkanoates (PHAs in order to resist changing and stressful conditions. However, the knowledge of bacterial PHA production in hypersaline microbial mats has been limited to date, particularly in regard to medium-chain length PHAs (mcl-PHAs, which have biotechnological applications due to their plastic properties. The aim of this study was to obtain evidence for PHA production in two hypersaline microbial mats of Guerrero Negro, Mexico by searching for PHA granules and PHA synthase genes in isolated bacterial strains and environmental samples. Six PHA-producing strains were identified by 16S rRNA gene sequencing; three of them corresponded to a Halomonas sp. In addition, Paracoccus sp., Planomicrobium sp. and Staphylococcus sp. were also identified as PHA producers. Presumptive PHA granules and PHA synthases genes were detected in both sampling sites. Moreover, phylogenetic analysis showed that most of the phylotypes were distantly related to putative PhaC synthases class I sequences belonging to members of the classes Alphaproteobacteria and Gammaproteobacteria distributed within eight families, with higher abundances corresponding mainly to Rhodobacteraceae and Rhodospirillaceae. This analysis also showed that PhaC synthases class II sequences were closely related to those of Pseudomonas putida, suggesting the presence of this group, which is probably involved in the production of mcl-PHA in the mats. According to our state of knowledge, this study reports for the first time the occurrence of phaC and phaC1 sequences in hypersaline microbial mats, suggesting that these ecosystems may be a novel source for the isolation of short- and medium-chain length PHA producers.

Full Text Available The aim of the conducted study was to determine to what extent the cultivation of sweet pepper lowers the phytotoxicity of a substrate. The examined material was a highly phytotoxic substrate due to repeated cucumber growing on it. This substrate was a mixture of pine and beech bark, low peat and sawdust. Five sweet pepper cultivars: Amador, Bell Boy, Culinar, Poznańska Słodka and WSE 2/82 were planted. During vegetation of the sweet pepper phytotoxicity and phenolics levels were determined in the substrate. It was found that cultivation of sweet pepper had a significant effect on lowering phytotoxicity and phenolics content in the substrate. Among the five tested cultivars, the highest detoxicating ability was exhibited by Amador, Culinar and WSE 2/82 while the Poznańska Słodka did not show such abilities.

In order to ascertain if Cu, Fe, and Zn are differentially accumulated in fish tissues, metal concentrations were measured in the muscle and liver of bycatch fish from the states of Sinaloa (189 specimens, 7 species) and Guerrero (152 individuals, 8 species) in the Mexican Pacific Coast during March and November 2011. Additionally, metal levels were compared with the maximum allowable limits set by international legislation and contrasted with similar ichthyofauna from other regions. Liver had more elevated concentrations of Cu (Sinaloa 28.3, Guerrero 16.3 μg g -1 ), Fe (Sinaloa 1098, Guerrero 636 μg g -1 ), and Zn (Sinaloa 226, Guerrero 186 μg g -1 ) than the muscle in fish from both studied areas. The relative abundances of analyzed metals in both tissues was Fe > Zn > Cu. As far as limits set by international legislation (Australia, India, New Zealand, Zambia), measured concentrations of Cu in the edible portion of fish were not found to be above the set values. In the case of Zn, the maximum allowable limits set by international legislation were exceeded by the Peruvian mojarra Diapterus peruvianus from Guerrero state (Mexican Pacific). No limits exist for Fe in the edible portion of fishery products in the national and international legislations.

Lanthanides are known, in some cases, to be sensitive to changes in water column or sediment chemistry, a fact that allows them to be used as environmental fingerprints. Nevertheless, the behavior of these elements in hypersaline environments is insufficiently understood, especially in those colonized by bacteria, archaea and eukarya halophiles. Extreme environments like the mentioned exist in the artificially-controlled ponds of the 'Exportadora de Sal' salt-producing enterprise located in Guerrero Negro (Baja California, Mexico). Sediment cores from various ponds were collected, subsampled and measured by ICP-MS and INAA. This allowed differencing the behavior of lanthanides and trace elements under a water column salinity gradient along the evaporation sequence of ponds. Sediment profiles (30 mm long), obtained in Pond 5, dominated by Ca and Mg precipitation and at the same time rich in organic matter due to bacterial mat presence, showed highs and lows of the shale-normalized patterns along different in-core depths. Two groups of elements could be distinguished with similar trends: set A (La, Ce, Pr and Nd) and set B (Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu). The first 'group A' had two prominent peaks at 15 mm and around 22 mm, whereas the 'group B' showed only slight increase at 15 mm and none at 22 mm. Microscopic analyses of prokaryotic cells of a stratified mat in Pond 5 (collected in 2004) showed filamentous bacteria and cyanobacteria with a cell abundance and morphotype richness maxima of prokaryotic cells in a chemocline from 3 mm to 7 mm depth which co-exists nine morphotypes of aerobic and anaerobic prokaryotes Microcoleus chthonoplastes, Leptolyngbya, Cyanothece, Geitlerinema, Spirulina, Chloroflexus, Beggiatoa, Chromatium and Thioploca. Below the 7 mm depth, oxygenic photosynthesis depletes and sulfur reducing compounds increase. The highs of the shale-normalized lanthanide contents of the 'group A' (at 15 mm depth) seem to correlate with the

Full Text Available El estudio analizó los cambios de cubierta y uso del suelo en la cuenca del río Coyuquilla, en Guerrero, México durante los periodos 1986-2000 y 2000-2011. Se elaboraron mapas de cubiertas y usos del suelo con base en la interpretación de imágenes de satélite. Durante el period 1986-2000 se observó una pérdida del 16% de la cubierta vegetal que afectó principalmente el bosque tropical seco con una tasa anual de deforestación de -3.7%. De 2000-2011 se observó una pérdida del 22% de cubierta vegetal y fue el bosque de encino, la cubierta que presentó la tasa más alta de deforestación (-5.54%. El incremento de los pastizales inducidos fue la principal causa de la pérdida de las cubiertas forestales. La altitud, la distancia a carreteras, la distancia a localidades y la pendiente del terreno fueron indicadores importantes para explicar la deforestación en los tres tipos de bosque y los dos periodos analizados. La evaluación de los modelos probabilísticos a través del análisis ROC muestra que los resultados se encuentran muy por arriba de un modelo aleatorio y fueron capaces de identificar las áreas más propensas a los CCUS del siguiente periodo (2000-2011 para las ocho transiciones analizadas.

Dengue is a serious public health problem with an important economic impact. This study used data from a cluster randomised controlled trial of community mobilisation for dengue prevention to estimate the household costs of treatment of dengue illness. It examined the economic impact of the trial intervention in the three coastal regions of Mexico's Guerrero State. The 2010 baseline survey covered households in a random sample of 90 clusters in the coastal regions; the clusters were randomly allocated to intervention or control and re-surveyed in 2012. The surveys asked about dengue cases in the last 12 months, expenditures on their treatment, and work or school days lost by patients and care givers. We did not assign monetary value to days lost, since a lost day to a person of low earning power is of equal or higher value to that person than to one who earns more. The 12,312 households in 2010 reported 1020 dengue cases in the last 12 months (1.9% of the sample population). Most (78%) were ambulatory cases, with a mean cost of USD 51 and 10.8 work/school days, rising to USD 96 and 11.4 work/school days if treated by a private physician. Hospitalised cases cost USD 28-94 in government institutions and USD 392 in private hospitals (excluding additional inpatient charges), as well as 9.6-17.3 work/school days. Dengue cases cost households an estimated 412,825 work/school days throughout the three coastal regions. In the follow up survey, 6.1% (326/5349) of households in intervention clusters and 7.9% (405/5139) in control clusters reported at least one dengue case. The mean of days lost per case was similar in intervention and control clusters, but the number of days lost from dengue and all elements of costs for dengue cases per 1000 population were lower in intervention clusters. If the total population of the three coastal regions had received the intervention, some 149,401 work or school days lost per year could have been prevented. The economic effect of

Full Text Available The King was the most important figure of all the Hellenistic period. He was an invincible warrior, wise ruler, god, general and medicine man. All these aspects of Hellenistic kingship are well known, however there is one subject that has not been studied by scholars, namely the capacity of Hellenistic kings to scare their enemies with their mere presence. In this paper we analyze stories attaching to Perdiccas, Olympias, Pyrrhus and Alexander the Great. Our opinion is that all these stories are based on the same model, the fight between Achilles and Trojans in the Iliad (XVIII 203-23. The aegis is studied as the mythical justification of the invincibility and terribleness of the kings. Furthermore, we consider the possibility that this phenomenon was associated with the Macedonian kings prior to Alexander.El rey fue la figura más importante de todo el período helenístico. Fue un guerrero invencible, un gobernante sabio, dios, general y curador. Todos estos aspectos sobre la monarquía helenística son bien conocidos, sin embargo hay una cuestión que no ha sido estudiada por los investigadores, es decir, la capacidad de los reyes helenísticos para hacer huir a sus enemigos conmoviéndolos por el miedo con su mera presencia. En este artículo analizamos historias relacionadas con Pérdicas, Olimpíade, Pirro y Alejandro Magno. Nuestra opinión es que todas estas historias están basadas en el mismo modelo, la lucha entre Aquiles y los troyanos en la Ilíada (XVIII 203-23. La égida es estudiada como la justificación mítica de la invencibilidad y terribilidad de los reyes. Además, contemplamos la posibilidad de que este fenómeno estuviese asociado con los reyes de Macedonia antes de Alejandro.

Water-rock-tailings interactions and sources of sulfur and metals in the subtropical mining region of Taxco, Guerrero (southern Mexico): A multi-isotopic approach

Multi-isotope (H, O, S, Sr, Pb) systems coupled with conventional (major and trace element) hydrogeochemical analysis were applied to determine the origin of water, to model water-rock-tailings interactions and for source apportionment of sulfur and associated toxic metals in the mining region of Taxco, Guerrero in southern Mexico. Oxygen and H isotopes indicate that meteoric water in the zone is rainwater undergoing varying degrees of isotopic fractionation by atmospheric evaporation whereas Sr isotopes trace the interaction of pristine water from volcanics of the regional recharge zone and subsequently flowing through sandstone and shale to spring points. Leachates form from two distinctive sources (spring water and surface water) having differential interactions with bedrocks prior to entering the tailings. Compared to pristine water, leachates are enriched in sulfate, metals (e.g. Fe, Mn, Pb and Zn) and metalloids (e.g. As). The sulfur isotopic composition of ore-sulfides, leachates, secondary precipitates, regional surface water and hypogenic sulfates is described in terms of a two-component mixing model with shale of Mexcala and limestone of Morelos formations representing the light and heavy end-members, respectively, whereas Sr isotopic composition is bracketed combining three lithogenic (Mexcala/Morelos, Tilzapotla and Taxco Schist) sources. Finally, leachates have a mixture of lead from ore-sulfides and Taxco Schist Formation (Family I) or from ore-sulfides alone (Family II). The application of multiple environmental isotopic techniques is an outstanding tool for elucidating complex interactions of water with bedrocks and tailings and for determining the source of sulfur and toxic metal from mining and other metal polluted environments. - Highlights: • We applied multi-isotope techniques to model water-bedrocks-tailings interaction. • Spring water records fractionation by evaporation and interaction with local rocks. • The sulfur cycle is modeled in

Valoración del paisaje de la selva baja caducifolia en la cuenca baja del río Papagayo (Guerrero, México

Arturos García Romero

2012-02-01

Full Text Available En la actualidad existe un amplio interés por el valor del paisaje como una alternativa de análisis ambiental, sin embargo, esta aproximación ha sido poco utilizada en los ecosistemas de México. El objetivo de este estudio fue determinar el valor del paisaje en la selva baja caducifolia (SBC de la cuenca baja del río Papagayo, Guerrero, México. Se realizó una clasificación jerárquica de paisajes y se aplicó un índice de valor del paisaje basado en cuatro indicadores: sensibilidad de laderas, fragmentación, calidad visual y significado social. Los resultados indican que el área está constituida por tres sistemas de paisajes –montañas, lomeríos y llanura aluvial– definidos por cambios morfo-litológicos y bioclimáticos; 17 subsistemas de paisajes y 16 paisajes elementales, definidos por los tipos de vegetación, usos de suelo y niveles de perturbación. El valor del paisaje fue heterogéneo, aunque tiende a ser mayor en los subsistemas montañosos de selvas y bosques, debido a que son más inaccesibles, por lo que el significado social y los niveles de perturbación y fragmentación se reducen. En contraste, los subsistemas de lomeríos con selva baja caducifolia tienen alto significado social debido a la cercanía y accesibilidad, lo cual favorece la intensificación de los usos del suelo, el incremento de la fragmentación y la caída de la calidad visual y del valor natural del paisaje.

Understanding the breeding patterns of Aedes aegypti in households and the factors associated with infestation are important for implementing vector control. The baseline survey of a cluster randomised controlled trial of community mobilisation for dengue prevention in Mexico and Nicaragua collected information about the containers that are the main breeding sites, identified possible actions to reduce breeding, and examined factors associated with household infestation. This paper describes findings from the Mexican arm of the baseline survey. In 2010 field teams conducted household surveys and entomological inspections in 11,995 households from 90 representative communities in the three coastal regions of Guerrero State, Mexico. We characterized Ae. aegypti breeding sites and examined the effect of two preventive measures: temephos application in water containers, and keeping the containers covered. We examined associations with household infestation, using bivariate and multivariate analysis adjusted for clustering effects. We conducted entomological inspections in 11,995 households. Among 45,353 water containers examined, 6.5% (2958/45,353) were positive for larvae and/or pupae. Concrete tanks (pilas) and barrels (tambos) together accounted for 74% of pupal productivity. Both covering water containers and inserting temephos were independently associated with a lower risk of presence of larvae or pupae, with the effect of covering (OR 0.22; 95% CIca 0.15-0.27) stronger than that of temephos (OR 0.66; 95% CIca 0.53-0.84). Having more than four water containers was associated with household infestation in both rural areas (OR 1.42; 95% CIca 1.17-1.72) and urban areas (1.81; 1.47-2.25), as was low education of the household head (rural: 1.27; 1.11-1.46, and urban: 1.39; 1.17-1.66). Additional factors in rural areas were: household head without paid work (1.31; 1.08-1.59); being in the Acapulco region (1.91; 1.06-3.44); and using anti-mosquito products (1.27; 1

Full Text Available The fluctuations of the number, biomass and composition of the heterotrophic community were studied daily for two days, according to depth, pH, Eh, O2 and organic carbon concentration within a zone of the canal between the Coyuca de Benítez lagoon (Guerrero, Mexico and the coastal waters. At the three moments of the day studied (6 am, 2 pm and 10 pm, the oxygen concentrations in the overlying water and in the superficial sediment layer were near air-saturation in the diurnal samplings (582 µM at 6 am and 665 µM at 2 pm, and sub-satured during the night (158 µM. In the sediments, the models of vertical distribution of Eh and organic carbon distributions were very irregular due to the bio-perturbation of the benthic, meio- and macrofauna, whose activity allows the superficial organic carbon to migrate towards sediment deeper layers. Vertical distribution of the different viable bacteria populations seems to be related to the hydrodynamic patterns of the communicating canal and sediments heterogeneity. In the sediment column, the heterotrophic bacteria total number varied from 6.8 to 20.3 x 108 cells cm-3. The highest heterotrophic bacterial biomass values were encountered during the diurnal samplings (39.2 µgC.l-1 at 6 am and 34.4 µgC.l-1 at 2 pm and the lowest during the night (9.7 µgC.l-1. The fluctuations of viable heterotrophic bacteria populations with different respiratory metabolisms (aerobic, microaerophilic and anaerobic can be explained by the existence of suboxic microniches that appear when particles of sediment are resuspended due to the water circulation and the benthic infauna excavating activity, that allows the supernatant water oxygen to penetrate through its galleries towards deeper sediment zones. The statistical analysis (Multiple lineal regression model r²≥ 0.5 showed that the on the whole, the hydrological parameters are not influence over the bacterial number and bacterial biomass distribution (r²≤ 0

La evaluación cuantitativa del alimento, se realizó a través de los métodos Volumétrico (V y Frecuencia de Aparición (FA y los Indices Medio Volumétrico (IMV e Importancia Relativa (IIR, los cuales se combinaron para determinar el espectro trófico de la tilapia. Se determinó que su dieta en la presa Infiernillo está constituida por: detritus y plantas vasculares como alimentos preferentes; algas unicelulares como alimento secundario y peces, insectos, semillas de gramíneas, algas filamentosas, cladóceros, ostrácodos, rotíferos y copépodos, como alimentos ocasionales. Se detectaron diferencias alimentarias entre juveniles y adultos y variaciones en el consumo de elementos alimentarios en la época de secas y lluvias. Se concluye que Oreochromis aureus es una especie omnívora con preferencia hacia el detritus y los restos de plantas vasculares. La alimentación esta determinada por la abundancia de las presas en el medio y en los adultos se basa preferentemente en el detritus.

The Mexican arm of the Camino Verde trial of community mobilisation for dengue prevention covered three coastal regions of Guerrero state: Acapulco, Costa Grande and Costa Chica. A baseline cross-sectional survey provided data for community mobilisation and for adapting the intervention design to concrete conditions in the intervention areas. Trained field teams constructed community profiles in randomly selected clusters, based on observation and key informant interviews. In each household they carried out an entomological inspection of water containers, collected information on socio-demographic variables and cases of dengue illness among household members in the last year, and gathered paired saliva samples from children aged 3-9 years, which were subjected to ELISA testing to detect recent dengue infection. We examined associations with dengue illness and recent dengue infection in bivariate and then multivariate analysis. In 70/90 clusters, key informants were unable to identify any organized community groups. Some 1.9% (1029/55,723) of the household population reported dengue illness in the past year, with a higher rate in Acapulco region. Among children 3-9 years old, 6.1% (392/6382) had serological evidence of recent dengue infection. In all three regions, household use of anti-mosquito products, household heads working, and households having less than 5 members were associated with self-reported dengue illness. In Acapulco region, people aged less than 25 years, those with a more educated household head and those from urban sites were also more likely to report dengue illness, while in Costa Chica and Costa Grande, females were more likely to report dengue illness. Among children aged 3-9 years, those aged 3-4 years and those living in Acapulco were more likely to have evidence of recent dengue infection. The evidence from the baseline survey provided important support for the design and implementation of the trial intervention. The weakness of

It is sustained on competency-based education and constructionism, due to they appeal to humanism to deal current problems. It is composed of four phases: committee conformation, theoretical and conceptual concerning analysis, construction and application of instruments on a PE, and identification of the cross-curricular theme level. Even though the proposed methodology is applied to the environment, it is feasible to adapt to other axes, such as human rights, multiculturalism, and poverty, relevant to the educational context of the state of Guerrero.

Geophysical studies in zones of high seismicity have showed differences in the content of radioactive material that is used in the study of the geochemical behavior of the subsoil. In an emanometric mapping of radon in soil realized in the Mexican Pacific coast were finding distinct levels in zones with different lithology. With the finality to know the mineralization types in two zones of study which are localized in the Guerrero coast and they belonging to terrains named Guerrero and Xolapa it was determined the mineralogic characteristics in two types of rocks. The identification of the rocks was realized by X-ray diffraction and was determined the elemental chemical composition using a scanning electron microscope. It was indicated in the results obtained that in the two types of rocks were found minerals such as: quartz, albite, microcline anortite, ferroactinolite and biotite. However, it was found differences between them by the presence of their mineralogic compounds because in the rock belonging to Xolapa terrain were presented whereas in the rock localized in the Guerrero terrain were presented sodic and potassic feldspars. The analysis by the Elemental Chemical Composition technique (Energy Dispersive Spectroscopy) corroborated the results obtained by the X-ray diffraction technique. (Author)

During investigations of fish parasites in the Neotropics (including the state of Veracruz and the Yucatán Peninsula in the Gulf of Mexico, the Chautengo Lagoon on the Pacific coast of the state of Guerrero in Mexico, and Lake Gatun in the Panama Canal), three monogenoidean (Dactylogyridae) species were found parasitizing the gills of gerreids (Gerreidae): Aristocleidus hastatus Mueller, 1936, was recovered from Eugerres plumieri (Cuvier) and Diapterus auratus Ranzani in Veracruz, from D. auratus and Diapterus rhombeus (Cuvier) in Yucatán, from Eugerres brasilianus (Cuvier) in Panama (all new hosts and geographical records), and from D. peruvianus (Cuvier) and Gerres cinereus (Walbaum) in Guerrero; Aristocleidus lamothei Kritsky and Mendoza-Franco, 2008, was recovered from E. plumieri in Veracruz and from D. rhombeus in Yucatan (new hosts and geographical records), and Aristocleidus sp. was recovered from G. cinereus in Guerrero. Results from this study suggest that species of Aristocleidus exhibit wide host specificity within gerreid fishes and that geminate species within this parasite genus may have originated with the formation of the Isthmus of Panama (3.1 to 3.5 ma). Evidence is also presented suggesting the potential role of the Panama Canal as a passageway allowing the interoceanic dispersal of Aristocleidus species across the isthmus.

Featured Image: Identifying a Glowing Shell

Kohler, Susanna

2018-05-01

New nebulae are being discovered and classified every day and this false-color image reveals one of the more recent objects of interest. This nebula, IPHASX J210204.7+471015, was recently imaged by the Andalucia Faint Object Spectrograph and Camera mounted on the 2.5-m Nordic Optical Telescope in La Palma, Spain. J210204 was initially identified as a possible planetary nebula a remnant left behind at the end of a red giants lifetime. Based on the above imaging, however, a team of authors led by Martn Guerrero (Institute of Astrophysics of Andalusia, Spain) is arguing that this shell of glowing gas was instead expelled around a classical nova. In a classical nova eruption, a white dwarf and its binary companion come very close together, and mass transfers to form a thin atmosphere of hydrogen around the white dwarf. When this hydrogen suddenly ignites in runaway fusion, this outer atmosphere can be expelled, forming a short-lived nova remnant which is what Guerrero and collaborators think were seeing with J210204. If so, this nebula can reveal information about the novathat caused it. To find out more about what the authors learned from this nebula, check out the paper below.CitationMartn A.

From the study of fire effects on individual soil properties to the development of soil quality indices. 1. The pioneer research

Science.gov (United States)

Mataix-Solera, Jorge; Zornoza, Raúl

2013-04-01

Although forest fires must be considered as a natural factor in Mediterranean ecosystems, the modification of its natural regime during last five decades has thansformed them in an environmental problem. In the Valencia region (E Spain) 1994 was the worst year in the history affecting more than 120,000 hectares. I started my Ph.D that year by studying the effects of fires in soil properties. The availability to be able to analyse a great set of different types of soil properties in the laboratories of University of Alicante allowed me to explore how fires could affect physical, chemical and micobiological soil properties. After years studying different soil properties, finding that several factors are involved, including: fire intensity and severity, vegetation, soil type, climate conditions, etc. (Mataix-Solera and Doerr, 2004; Mataix-Solera et al., 2008, 2011) my research as Ph-D supervisor has been focussed to investigate more in depth some selected properties, such as aggregate stability and water repellency (Arcenegui et al., 2007, 2008). But one of the main problems in the studies conducted with samples affected by wildfires is that for the evaluation of the fire impact in the soil it is necessary to have control (unburned) soil samples from a similar non-affected near area. The existing spatial variability under field conditions does not allow having comparable samples in some acses to develop a correct assessment. With this idea in mind one of my Ph.D researcher (R. Zornoza) dedicated his thesis to develope soil quality indices capable to assess the impact of soil perturbations without comparing groups of samples, but evaluating the equilibrium among different soil properties within each soil sample (Zornoza et al., 2007, 2008). Key words: wildfire, Mediterranean soils, soil degradation, wàter repellency, aggregate stability References: Arcenegui, V., Mataix-Solera, J., Guerrero, C., Zornoza, R., Mayoral, A.M., Morales, J., 2007.

Full Text Available Since the 1970s, interest in caring for the environment has gained traction and the environmental education movement has gained momentum. The Talloires Declaration was the first document to incorporate sustainable development into higher education. After that, higher education institutions assumed the social responsibility of training human resources with a sustainable vision. This study aimed to contribute to the design of indicators that could be used to evaluate the efficacy of the sustainability taught at the Universidad Autónoma de Guerrero (Autonomous University of Guerrero in Mexico. We administered a survey to 63 teachers and 511 students from four academic units in high schools, and undergraduate and postgraduate programs. The answers were analyzed using the F-test and the variable descriptions. For the environmental, social and economic indicators, the satisfaction levels of teachers and students were more positive in graduate and undergraduate programs than in the high school. To determine the efficacy of the teaching function in terms of sustainable education, as well as to fulfill the commitments acquired to achieve sustainability, institutional processes need to be strengthened.

Full Text Available A total of 206 serum samples from children (3-14 years old living in the Amador County (La Chorrera District, Province of Panama were screened by indirect immunofluorescence antibody test (IFAT for the presence of antibodies against Trypanosoma cruzi. Positive sera were confirmed by recombinant enzyme-linked immunosorbent assay (ELISA and Western blot analysis. The presence of blood trypanosomes was investigated by hemoculture and subsequently identify by a duplex polymerase chain reaction (PCR followed by dot blot hybridization. The results indicated a prevalence of 9.7% for trypanosome infections, a seroprevalence of 2.9% against T. cruzi and a predominance of T. rangeli infection (6.8%. The immunological and clinical implications of these findings are discussed.

De la Inmaculada a la Mujer Águila del Apocalipsis, imágenes marianas novohispanas 1555-1648

Directory of Open Access Journals (Sweden)

Nathalie Augier de Moussac

2013-07-01

Full Text Available The mid XVI th century marian frescoes of the Franciscan convents of Huejotzingo, Puebla, are visual proves of the Immaculist devotion of the first missionaries. Amongst the numerous engravings from Northern Europe, which invaded New Spain via the Spanish port of Seville from the Conquest onwards, one image depicts the Virgin as the Tota Pulchra. Within the evangelisation of the New world and the intensive reproduction process it involved to impose Christian iconographies onto the American landscape, the type of the Tota pulchra was reinterpreted with an apocalyptic point of view. The Historia de los Indios de la Nueva España written by one of the first Franciscan friars who came to preach in New Spain, Toribio de Benavente, known as Motolinia, lays the principles of the Franciscan utopia derived from the millenarian theories of Joachim of Fiore, announcing the advent of the Age of the Holy Spirit and the reign of the New Eve. This particular context fostered new epiphanies around 1555, amongst which the image of the Mexican Guadalupe stands first. However it would not be until the publication, nearly a century later of Miguel Sánchez’s « Imagen de la Virgen María, Madre de Dios de Guadalupe…»(1648, whose text, largely inspired by the Augustinian exegesis identifies the Virgin of the Guadalupe with the Woman of the Revelation, that the image of the Tepeyac would acquire its canonical status of acheiropoieta and reveals itself as the living symbol of the New American Church.

Full Text Available Resumen: La región de los Altos de Jalisco es una zona turística basada en la religiosidad y principalmente en la devoción hacia la Virgen de la Inmaculada Concepción más conocida como “Virgen de San Juan de los Lagos”. Debido a la canonización que hizo el Papa Juan Pablo II de 25 mártires cristeros, han urgido en esta zona, nuevos centros de devoción religiosa. En el caso de Santa Ana de Guadalupe se estima que recibe alrededor de un millón de visitantes anualmente. Es sorprendente el crecimiento logrado por este último santuario. Se ha convertido en un importante centro de turismo religioso; lo asombroso es que está ubicada a 20 kilómetros de San Juan de los Lagos, segundo centro religioso del país, lo que hace aún más interesante la manera en que han podido integrarse estos dos sitios.

Full Text Available Las condiciones medioambientales en que se encuentran las obras de arte son un factor que determina su conservación. Optimizar estos parámetros beneficia la conservación de las mismas. El Centro José Guerrero (Granada cuenta con una colección permanente (gráfica y pictórica del pintor José Guerrero, sobre la que se ha realizado el estudio que nos ocupa. El edifico no ofrece una temperatura similar en sus espacios expositivos, ni la temperatura de superficie de los cuadros en exposición es homogénea en toda su extensión, lo que se ha podido comprobar mediante técnicas analíticas de temperatura de superficie, que han reflejado con claridad las condiciones reales de temperatura de las obras, que también resultan ser diferentes a las mediciones térmicas globales del ambiente de las salas, con las consiguientes alteraciones físicas y químicas que este fenómeno puede originar en los materiales de los trabajos artísticos. Debido a ello, razón, este hecho debe ser valorado, con la intención de evitarlo o minimizarlo convenientemente.

THREE STORIES FROM MANUEL GUERRERO’S PROSA LITERARIA: “THE GOLD TREE”, “ANTAMOK”, AND “SIANING”

2009-12-01

Full Text Available The English translations presented here attempt to preserve and make more accessible three literary pieces originally written in Spanish by Filipino writer Manuel Guerrero (1877-1919: Ël arbol de oro”, that is, “The Gold Tree”, “Antamok” and “Sianing.” These three stories are considered his best. Included in the collection Prosa Literaria (1921, they are almost impossible to find and will most likely become even more so as time goes by. And yet, Manuel Guerrero, who also earned a name for himself as a medical doctor, must be made known and appreciated by more scholars throughout the world because he was one of the best writers of the “The Golden Age of Fil-Hispanic Literature” (1903-1942. A journalist early in life, he contributed to such newspapers as La Republica Filipina (1898-1899, La Independencia (1898-1900, and La Patria (1899-1900. He also penned articles and sketches on Philippine customs, folkways and legends which led to his making a mark on Philippine literature in Spanish. His writings are a significant part of our Fil-Hispanic literary heritage, and our cultural patrimony. It would be a great loss if we were to set these aside completely.

Full Text Available The outstanding work developed by Maria Guerrero through her long activity as actress and producer, began in the 1894-95 season with two important achievements. On one side, she attracted around her the most important and compromised authors, initiating the necessary innovation in contemporary theatre. On the other, thank to her, the Spanish Classical Theatre had one of its best moments. To this Theatre the actress dedicated one day per week, the «classic Mondays», and with its performances she travelled all over Europe and South America. This article is intended to study the complex work to stage Entre bobos anda el juego, the play that inaugurated the first complete season at the Teatro Español in Madrid (1895- 96. It is important to emphasize her scenographic and artistic work, and Donato Jiménez as well, one of the best interpreters as Don Lucas del Cigarral.La gran labor dramática desarrollada por María Guerrero en su larga vida escénica como actriz y empresaria, arrancó en la temporada teatral 1894-95 con dos grandes logros.

De otra, el teatro clásico español vivió en los años finales del siglo XIX, gracias a la Guerrero, uno de sus momentos más esplendorosos. A él dedicó la actriz un día a la semana, los «lunes clásicos», y con él se paseó por Europa y América del Sur. Al estudio de la puesta en escena de Entre bobos anda el juego, obra con la que inauguró la primera temporada completa en el teatro Español de Madrid (1895-1896, va dedicado este trabajo, en el que se destaca la cuidada labor escenográfica y artística de la joven empresaria y actriz, así como la que desarrolló Donato Jiménez, uno de los mejores intérpretes de Don Lucas del Cigarral.

Diagnosis of coccidioidomycosis in a non-endemic area: Inference of the probable geographic area of an infection.

Fernández, Ramón; Arenas, Roberto; Duarte-Escalante, Esperanza; Frías-De León, María Guadalupe; Vega Memige, María Elisa; Acosta Altamirano, Gustavo; Reyes-Montes, María Del Rocío

Coccidioidomycosis is one of the most important endemic mycoses in Northern Mexico. However, diagnosing this disease can be challenging, particularly in patients who do not reside in endemic areas. The case of a Mexican HIV+ patient who developed fever, general malaise, a severe cough, and dyspnea during a stay in Acapulco, Guerrero, Mexico, is presented. Since various diseases are endemic to the state of Guerrero, the doctors originally suspected that the patient had contracted influenza A (H1N1), Q fever, or tuberculosis. All the diagnostic tests for those diseases were negative. The patient had received numerous mosquito bites while staying in Acapulco, and a nodule had appeared on his right cheek. Therefore, malaria, cryptococcosis, and histoplasmosis were also suspected, but those infections were also ruled out through diagnostic tests. A direct microscopic examination was performed using KOH on a sample taken from the cheek nodule. The observation of spherules suggested the presence of a species of Coccidioides. The fungus was isolated, and its identity was confirmed by phenotypic and molecular methods. The geographic area in which the infection was likely acquired was identified by random amplified polymorphic DNA (RAPD) analysis. The results suggested a probable endogenous reactivation. This clinical case illustrates the difficulties associated with diagnosing coccidioidomycosis in non-endemic areas. Copyright © 2017. Publicado por Elsevier España, S.L.U.

The Mexican mesozoic uranium province: its distribution and metallogeny

International Nuclear Information System (INIS)

Bazan B, S.

1981-01-01

The distribution of uranium scattered in sedimentary terrains of the continental jurassic such as those found in the Tlaxiaco-Guerrero Basin encourage the outlook for uncovering extensive new deposits of strato-bound uranium belonging to the Mexican mesozoic in other structurally similar intercratonic basins. Stratographic and paleographic structural references define the simultaneous evolution of five sedimentary basins during the Mexican geotechtonic cycle: 1. the Tlaxiaco-Guerrero basin, 2. the Huayacocotla basin, 3. the Gulf of Sabinas basin, 4. the Chihuahua basin and 5. the Sonora basin. From the various lithostratographic formations in them we favourably infer the presence of intermountainous mesozoic concentrations of uranium sediments leached from crystalline precambric packets and from nevadian plutonites and volcanic rocks. During the metallogeny process described under the techtonic evolution of the Mexican structural belt, the presence is established of extensive terciary hydrothermal uranium deposits in the districts of Aldama, Chihuahua; Coneto-El Rodeo, Durango; Vizarron de Montes, Queretaro; Tlaucingo, Puebla; Los Amoles, Sonora; El Picacho, Sonora; Amalia Margarita, Coahuila; etc., scattered in sandstones and sinters of the continental mesozoic and shifted during the postorogenic phase of the Mexican geotectonic cycle. The extensive mesozoic province defined within the Mexican territory favourable to large deposits of uranium, scattered and strato-bound in triassic, jurassic and cretaceous sandstone and sinters, could resolve future demands for energetics within a modified philosophy and resourceful policy of regional mining.

Kinematics and age of Early Tertiary trench parallel volcano-tectonic lineaments in southern Mexico: Tectonic implications

Science.gov (United States)

Martini, M.; Ferrari, L.; Lopez Martinez, M.; Cerca Martinez, M.; Serrano Duran, L.

2007-05-01

We present new geological, structural, and geochronological data that constrain the timing and geometry of Early Tertiary strike slip deformation in southwestern Mexico and its relation with the concurrent magmatic activity. Geologic mapping in Guerrero and Michoacan States documented two regional WNW trending volcano-tectonic lineaments sub parallel to the present trench. The southernmost lineament runs for ~140 km from San Miguel Totolapan area (NW Guerrero) to Sanchiqueo (SE Michoacan), and passes through Ciudad Altamirano. Its southeastern part is marked by the alignment of at least eleven silicic to intermediate major domes as well as by the course of the Balsas River. The northwestern part of the lineament is characterized by ductile left lateral shear zones in Early Tertiary plutonic rocks observed in the Rio Chiquito valley. Domes near Ciudad Altamirano are unaffected by ductile shearing and yielded a ~42 Ma 40Ar/39Ar age, setting a minimum age for this deformation. The northern volcano-tectonic lineament runs for ~190 km between the areas of Huitzuco in northern Guerrero and the southern part of the Tzitzio fold in eastern Michoacan. The Huautla, Tilzapotla, Taxco, La Goleta and Nanchititla silicic centers (all in the range 37-34 Ma) are emplaced along this lineament, which continues to the WNW trough a mafic dike swarm exposed north of Tiquicheo (37-35 Ma) and the Purungueo subvolcanic body (~42 Ma). These rocks, unaffected by ductile shearing, give a minimum age of deformation similar to the southern Totolapan-Sanquicheo lineament. Post ~42 Ma deformation is essentially brittle and is characterized by several left lateral and right lateral transcurrent faults with typical Riedel patterns. Other trench-parallel left lateral shear zones active in pre-Oligocene times were recently reported in western Oaxaca. The recognizing of Early Tertiary trench-parallel and left-lateral ductile shearing in internal areas of southern Mexico suggest a field of widely

2015-12-01

A region-wide survey was conducted in the tropical area of Tierra Caliente, State of Guerrero, Mexico to estimate the prevalence of subclinical bovine mastitis (SCM), distribution of mastitis pathogens, and in vitro antimicrobial susceptibility of different mastitis pathogens in dairy farms. In total, 1036 quarter milk samples were obtained from 259 cows at 87 different dairy farms. Collected quarter milk samples were submitted for California Mastitis Test (CMT), bacteriological examination, and testing for antimicrobial susceptibility. Overall prevalence of SCM in the studied area was 20.5 %. Prevalence in the different regions was as follows: 28 % in Arcelia municipality, 21 % in Tlalchapa municipality, 19.4 % in Pungarabato municipality, and 14.3 % in Finch Cutzamala municipality. Of all positive isolates, 97.5 % were Gram-negative bacteria. Moreover, of all positive isolates, 37.5 % were Proteus vulgaris, 25 % Salmonella spp., 12.5 % Enterobacter aerogenes, and 10 % Escherichia coli. Klebsiella pneumonia and E. coli were sensitive for netilmicin antimicrobial. However, E. coli was sensitive for pefloxacin and gentamicin with a sensitivity for pefloxacin for E. aerogenes, while Staphylococci were sensitive for gentamicin and dicloxacillin. It could be concluded that practices such as the implementation of mastitis control programs, improved milking hygiene together with an intramammary treatment with netilmicin, pefloxacin, and gentamicin antimicrobials should be considered for mastitis prevention in the study area of Tierra Caliente, in the tropical area of Guerrero, Mexico.

The Acoustic Dimension of Social Protest: Notes from an Ethnography of Sound

Directory of Open Access Journals (Sweden)

José Luis Martin

2017-09-01

Full Text Available In this article we analyse the role of sound in protest marches from an interactional communication perspective. We present an inter-disciplinary proposal for the development of a methodology suited for the ethnography of sound in the contemporary context. We also present the results of the application of this methodology in the context of the protests against the forced disappearance of the 43 students from Ayotzinapa, Guerrero in Mexico. The study questions the social modes of sound as the acoustic materialization of the communication processes within specific sound contexts.

We evaluated different strains of the rotifer Asplanchna brightwellii collected from central Mexico using morphology, morphometry and molecular tools (CO1 and ITS). Three distinct clonal populations from each of the 3 regions (Mexico City, State of Mexico and State of Guerrero) were established under laboratory conditions. For a given waterbody, morphometric comparisons within the populations of A. brightwellii showed almost stable measurements of trophi and with no statistically significant differences among them (p > 0.05). However, asplanchnid body length and width as well as the cyst diameter varied significantly depending on the waterbody from which A. brightwellii was collected. The smallest adults (about 700 microm) were from Valerio Trujano lake (Guerrero State) samples while the largest were from Xochimilco lake. Similar tendencies were reflected in the diameter of resting eggs. In addition, morphologically the cysts of A. brightwellii from the three waterbodies showed slightly different pattern. The number of globular structures on the surface of cysts was smaller for Valerio Trujano strain, while these were larger and less numerous for both Xochimilco and Zumpango strains. The ITS region tree displayed two groups Xochimilco and Valerio Trujano -Zumpango, this analysis did not reflect the morphological grouping; on the contrary the CO1 gene tree separated the populations according to morphological clusters and location (Xochimilco, Valerio Trujano and Zumpango lakes). When the tree was built using the combination of both ITS and CO1 sequences, the phylogenetic relationships observed on CO1 gene were consistent; but showed differences with the relationships observed on ITS region tree (only two groups).

Modelling the fine and coarse fraction of heavy metals in Spain

Science.gov (United States)

García Vivanco, Marta; González, M. Angeles

2014-05-01

Heavy metals, such as cadmium, lead, nickel, arsenic, copper, chrome, zinc and selenium, are present in the air due to natural and anthropogenic emissions, normally joined to particles. These metals can affect life organisms via inhalation or ingestion, causing damages in human health and ecosystems. Small particles are inhaled and embebed in lungs and alveolus more easily than coarse particles. The CHIMERE model is a eulerian air quality model extensively used in air quality modelling. Metals have been recently included in this model in a special version developed in the CIEMAT (Madrid, Spain) modelling group. Vivanco et al. (2011) and González et al. (2012) showed the model performance for some metals in Spain and Europe. However, in these studies, metals were considered as fine particles. Some studies based on observed heavy metals air concentration indicate the presence of metals also in the coarse fraction, in special for Cu and Zn. For this reason, a new attempt of modelling metals considering a fine (Arsenic, Lead, Cadmium and Nickel Ambient Air Concentrations in Spain, 2011.

Variable merozoite surface antigens of Babesia bovis are exposed glycoproteins having a role in erythrocyte invasion. Members of this gene family include msa-1 and msa-2 (msa-2c, msa-2a(1), msa-2a(2) and msa-2b). To determine the sequence variation among B. bovis Mexican isolates using msa-2b as a genetic marker, PCR amplicons corresponding to msa-2b were cloned and plasmids carrying the corresponding inserts were purified and sequenced. Comparative analysis of nucleotide and deduced amino acid sequences revealed distinct degrees of variability and identity among the coding gene sequences obtained from 16 geographically different Mexican B. bovis isolates and a reference strain. Clustal-W multiple alignments of the MSA-2b deduced amino acid sequences performed with the 17 B. bovis Mexican isolates, revealed the identification of three genotypes with a distinct set each of amino acid residues present at the variable region: Genotype I represented by the MO7 strain (in vitro culture-derived from the Mexico isolate) as well as RAD, Chiapas-1, Tabasco and Veracruz-3 isolates; Genotype II, represented by the Jalisco, Mexico and Veracruz-2 isolates; and Genotype III comprising the sequences from most of the isolates studied, Tamaulipas-1, Chiapas-2, Guerrero-1, Nayarit, Quintana Roo, Nuevo Leon, Tamaulipas-2, Yucatan and Guerrero-2. Moreover, these three genotypes could be discriminated against each other by using a PCR-RFLP approach. The results suggest that occurrence of indels within the variable region of msa-2b sequences can be useful markers for identifying a particular genotype present in field populations of B. bovis isolated from infected cattle in Mexico.

Fermentation couples Chloroflexi and sulfate-reducing bacteria to Cyanobacteria in hypersaline microbial mats

Directory of Open Access Journals (Sweden)

Jackson Z Lee

2014-02-01

Full Text Available Past studies of hydrogen cycling in hypersaline microbial mats have shown an active nighttime cycle, with production largely from Cyanobacteria and consumption from sulfate-reducing bacteria (SRB. However, the mechanisms and magnitude of hydrogen cycling have not been extensively studied. Two mats types near Guerrero Negro, Mexico -- permanently submerged Microcoleus microbial mats (GN-S, and intertidal Lyngbya microbial mats (GN-I -- were used in microcosm diel manipulation experiments with 3-(3,4-dichlorophenyl-1,1-dimethylurea (DCMU, molybdate, ammonium addition, and physical disruption to understand the processes responsible for hydrogen cycling between mat microbes. Across microcosms, H2 production occurred under dark anoxic conditions with simultaneous production of a suite of organic acids. H2 production was not significantly affected by inhibition of nitrogen fixation, but rather appears to result from constitutive fermentation of photosynthetic storage products by oxygenic phototrophs. Comparison to accumulated glycogen and to CO2 flux indicated that, in the GN-I mat, fermentation released almost all of the carbon fixed via photosynthesis during the preceding day, primarily as organic acids. Across mats, although oxygenic and anoxygenic phototrophs were detected, cyanobacterial [NiFe]-hydrogenase transcripts predominated. Molybdate inhibition experiments indicated that SRBs from a wide distribution of dsrA phylotypes were responsible for H2 consumption. Incubation with 13C-acetate and nanoSIMS (secondary ion mass-spectrometry indicated higher uptake in both Chloroflexi and SRBs relative to other filamentous bacteria. These manipulations and diel incubations confirm that Cyanobacteria were the main fermenters in Guerrero Negro mats and that the net flux of nighttime fermentation byproducts (not only hydrogen was largely regulated by the interplay between Cyanobacteria, SRBs, and Chloroflexi.

Dispersive component of the free surface energy of a Colombian semianthracite type coal - Paramo de Guerrero - was determined by Inverse Gas Chromatography (IGC), at zero coverage injecting the series of n-alkanes at 313, 333, 353 and 373 K. For the retention time, the mass center determination was used instead of the maximum peak in the chromatograms. The free surface energy (-{Delta}G{sub A}) increase linearly with the carbon atom number to the alkanes but is not constant due, probably to the conformational structure of the probes. The IGC study of the adsorption process in function of the temperature, provides the respective Enthalpy and Entropy values. (orig.)

A Mexican zeolite (clinoptilolite) from Taxco, Guerrero, was partially stabilized with sodium cations. Radioactive Cobalt ( 60 Co) was used to study the Co 2+ sorption in the stabilized zeolite (Na + ). It was found that sorption in general does not favour the diffusion of cobalt between framework, it explains because of it is a natural zeolite and its composition heterogeneous decrease its exchange capacity by the generated competence to the existence other type of exchange ions. The cobalt retention reached the highest level, around 0.408 m eq Co 2+ /g in the Na-Clinoptilolite. The crystallinity of the aluminosilicates was maintained during experiments, it was verified by XRD patterns. (Author)

Full Text Available Plicopurpura patula pansa es un caracol carnívoro característico de las costas rocosas del Pacífico mexicano. Presenta una glándula hipobraquial que secreta un fluido que adquiere una coloración púrpura en presencia de oxígeno y luz solar. Se determinó el arreglo espacial del caracol en playas que difieren en cuanto al tipo de sustrato, exposición al oleaje y pendiente de playa. Se calculó entre 0.1522 y 0.5435. Las menores fluctuaciones del Ip se presentaron en 5 playas que tienen en común sustratos fijos, gran cantidad de grietas y oquedades. Las mayores fluctuaciones correspondieron a 4 playas con sustratos móviles, como los cantos rodados.Plicopurpura patula pansa is a carnivore snail common of the Mexican Pacific rocky shores. Its hypobranchial gland produces a secretion that, in the presence of oxygen and sunlight, becomes purple. We determined the spatial distribution of the snail on beaches that differ in substratum, wave exposure, and the degree substratum’s inclination. The average snail density was calculated. Using the Morisita index (Id and the Morisita standardized index (Ip, we found that in 96.3% of the samples taken, the snails were distributed according to a patchy distribution. The rest of the time, their distribution was random. The I index oscillated between 0.1522 and 0.5435. Smaller fluctuations of the I index were observed in 5 beaches with substrata that were more stable and had a larger number of cracks and crevices than those on beaches with mobile substrata, such as rolled rocks.

Gertrudis Gómez de Avellaneda desde otro ápice: su labor como prologuista

Full Text Available The literary work of Gertrudis Gómez de Avellaneda was devoted mostly to three genres: poetry, narrative and drama. Nevertheless, there remain some important but less considered facets of her writing interests, such as her remarkable work as a columnist —where we can find texts later judged real essays— and as a literary critic. Among the latter I highlight her brief, but no less important, role as a prologue writer, dedicated absolutely to Cuban authors of varying significance: the Countess of Merlín, Luisa Pérez de Zambrana, Teodoro Guerrero and Ángel Mestre. Our contribution analyses the diverse foundations that support these texts, written in different moments between 1844 and 1865, where her literary and civic obsessions, and the theme of the “gender mark” that pervades her works, are exposed.La obra literaria de Gertrudis Gómez de Avellaneda se cumplió fundamentalmente en tres géneros: poesía, narrativa y teatro. Quedan a su favor otros flancos importantes y poco estudiados de su labor, tales como su apreciable quehacer como articulista en trabajos devenidos, a veces, en verdaderos ensayos, y como crítica literaria. En esta última coloco su breve, pero no menos relevante servicio como prologuista, ejercido siempre sobre obras de autores cubanos de mayor o menor relevancia: la condesa de Merlín, Luisa Pérez de Zambrana, Teodoro Guerrero y Ángel Mestre. Nuestra propuesta valora los presupuestos de diverso carácter expuestos en esos trabajos, escritos en diferentes momentos entre 1844 y 1865, donde quedan reveladas sus propias inquietudes literarias, cívicas y también la marca de género, tan presente en el conjunto de su obra.

Sedimentary Record of the Back-Arc Basins of South-Central Mexico: an Evolution from Extensional Basin to Carbonate Platform.

The Lower Cretaceous depositional systems of southwestern Oaxaquia, in south-central Mexico, were controlled by tectonic processes related to the instauration of a continental arc and the accretion of the Guerrero arc to mainland Mexico. The Atzompa Formation refers to a succession of conglomerate, sandstone, siltstone, and limestone that crop out in southwestern Mexico with Early Cretaceous fauna and detrital zircon maximum depositional ages. The sedimentary record shows a transition from early fluvial/alluvial to shallow marine depositional environments. The first stage corresponds to juvenile fluvial/alluvial setting followed by a deep lacustrine depositional environment, suggesting the early stages of an extensional basin. The second stage is characterized by anabranched deposits of axial fluvial systems flowing to the NE-SE, showing deposition during a period of rapid subsidence. The third and final stage is made of tidal deposits followed, in turn, by abrupt marine flooding of the basin and development of a Barremian-Aptian carbonate ramp. We interpret the Tentzo basin as a response to crustal extension in a back-arc setting, with high rates of sedimentation in the early stages of the basin (3-4 mm/m.y), slower rates during the development of starved fluvial to tidal systems and carbonate ramps, and at the top of the Atzompa Formation an abrupt deepening of the basin due to flexural subsidence related to terrane docking and attendant thrusting to the west. These events were recorded in the back-arc region of a continental convergent margin (Zicapa arc) where syn-sedimentary magmatism is indicated by Early Cretaceous detrital and volcanic clasts from alluvial fan facies west of the basin. Finally, and as a response to the accretion of the Guerrero superterrane to Oaxaquia during the Aptian, a carbonate platform facing toward the Gulf of Mexico was established in central to eastern Oaxaquia.

The official version of events does not answer many questions of the family, nor it does answer the questions of the society as a whole.

The impact of a control program is evaluated to eventually eradicate taeniasis-cysticercosis (Taenia solium) based on education and vaccination of pigs. The prevalence of porcine cysticercosis was estimated using tongue inspection, ultrasound and determination of antibodies, before and three years after the application in three regions of the state of Guerrero. A significant reduction in the prevalence of porcine cysticercosis of 7 to 0.5% and 3.6 to 0.3% estimated by tongue examination or ultrasound respectively (ptaeniasis-cysticercosis establishes the program's effectiveness in preventing infection. The sustained presence of antibodies, compatible with contact of Taenia solium or other related helminths, underlines the importance of maintaining interventions to achieve eradication.

Ni "almas bellas" ni "guerreros justos": mujeres implicadas en violencia política

Full Text Available La implicación de las mujeres en violencia política ha sido invisibilizada, marginalizada y desvalorizada. Estudios recientes sobre su participación en conflictos bélicos, movimientos de resistencia, movimientos revolucionarios y grupos terroristas a lo largo del siglo XX y XXI permiten rescatar la visibilidad de este fenómeno así como interpretarlo a la luz de los procesos psicosociales del contexto, que son similares a los que explican la implicación de los varones: en particular, los procesos grupales y comunitarios de carácter psicosocial, la ideología política, y la transformación de la identidad de género en un momento histórico de conquista de la igualdad. Los estereotipos sexistas e incluso algunas interpretaciones de la psicología diferencial de los géneros contribuyen a distorsionar la explicación de la implicación de las mujeres en esta y otras formas de violencia. The involvement of women in political violence has been hidden, marginalized and devalued. Recent studies about involvement of women in armed conflicts, resistance movements, revolutionary movements and terrorist groups throughout the twentieth and twentieth-first centuries can rescue the visibility of this phenomenon and interpret it in the light of the psychosocial processes of the context, similar to those that explain the involvement of men: particularly, group and community psychosocial processes, political ideology, and gender identity transformation towards women equality. Sexist stereotypes and even some interpretations of the psychology of gender differences help to distort the explanation of the involvement of women in this and other forms of violence.

We study estimation of the date of change in persistence, from [Formula: see text] to [Formula: see text] or vice versa. Contrary to statements in the original papers, our analytical results establish that the ratio-based break point estimators of Kim [Kim, J.Y., 2000. Detection of change in persistence of a linear time series. Journal of Econometrics 95, 97-116], Kim et al. [Kim, J.Y., Belaire-Franch, J., Badillo Amador, R., 2002. Corringendum to "Detection of change in persistence of a linear time series". Journal of Econometrics 109, 389-392] and Busetti and Taylor [Busetti, F., Taylor, A.M.R., 2004. Tests of stationarity against a change in persistence. Journal of Econometrics 123, 33-66] are inconsistent when a mean (or other deterministic component) is estimated for the process. In such cases, the estimators converge to random variables with upper bound given by the true break date when persistence changes from [Formula: see text] to [Formula: see text]. A Monte Carlo study confirms the large sample downward bias and also finds substantial biases in moderate sized samples, partly due to properties at the end points of the search interval.

Poor insight is found in up to 80% of schizophrenia patients and has been associated with multiple factors of which cognitive functioning, social and environmental factors. Few studies have explored associations between patient insight and that of their biological parents', and the influence of parental factors. Insight was assessed in 41 patients and their biological parents with Amador's Scale for the assessment of Unawareness of Mental Disorder (SUMD). Parents' knowledge about schizophrenia and critical attitudes were assessed with validated self-report questionnaires. Both groups underwent cognitive assessments for working memory and executive functioning. Insight in patients and their parents was not associated for any of the SUMD dimensions but a significant correlation was found between patient and parent awareness of treatment effect for patient-parent dyads with frequent daily contact. Low parental critical attitude was associated with higher patient awareness of symptoms and a high parental memory task score with high patient insight. Our study is the first to suggest a possible influence of parental factors such as critical attitudes and cognitive performance on patient insight. Copyright © 2015 Elsevier Ireland Ltd.

Full Text Available The following study analyses the nature of the self-defence forces that arose in February 2013 in Michoacán, a Mexican state located on the Pacific coast. The novelty of this movement is underlined: its ambiguity with respect to the law, its use of modern tactics and its continuity with the ideological assumptions of the “war on drugs”. Furthermore, questions are posed about the similarities and differences from forms of violence such as paramilitarism and insurgency, and from other groups such as the community police operating in Guerrero state, which orders the Michoacán. Finally, the paper concludes with the issues that the rise, tolerance and legalisation of this type of movement raise for the country.

In this work is evaluated the activity of the alpha emitters, uranium and plutonium, in sand samples and seawater coming from diverse points of the Mexican Pacific Coast (Baja California, Jalisco, Colima and Guerrero). The used techniques were: radiochemistry separation and alpha spectrometry, with these techniques could be observed that the sand contains natural uranium and trace quantities of 239 Pu and 240 Pu combinations. The biggest activity in Pu was found in Finisterra, Baja California Sur (0.13 Bq/kg) and the minor (0 Bq/kg) in Miramar, Colima. The relationship between the geographical localization and the Pu activity suggests that while there is more interaction of the site with the oceanic currents, more is the content of Pu in the sands of the coast.

This descriptive study investigates the genetic structure of seven Mexican indigenous populations (Mixteca Alta, Mixteca Baja, Otomies, Purepecha, Nahuas-Guerrero, Nahuas-Xochimilco, and Tzeltales) on the basis of five PCR-based polymorphic DNA loci: LDLR, GYPA, HBGG, D7S8, and GC. Genetic distance and diversity analyses indicate that these Mexican indigenous are similar and that more than 96% of the total gene diversity (H(T)) can be attributed to individual variation within populations. Mixteca-Alta, Mixteca-Baja, and Nahuas-Xochimilco show indications of higher admixture with European-derived persons. The demonstration of a relative genetic homogeneity of Mexican Indians for the markers studied suggests that this population is suitable for studying disease-marker associations in the search for candidate genes of complex diseases.

The evolving interaction of low-frequency earthquakes during transient slip.

2016-04-01

Observed along the roots of seismogenic faults where the locked interface transitions to a stably sliding one, low-frequency earthquakes (LFEs) primarily occur as event bursts during slow slip. Using an event catalog from Guerrero, Mexico, we employ a statistical analysis to consider the sequence of LFEs at a single asperity as a point process, and deduce the level of time clustering from the shape of its autocorrelation function. We show that while the plate interface remains locked, LFEs behave as a simple Poisson process, whereas they become strongly clustered in time during even the smallest slow slip, consistent with interaction between different LFE sources. Our results demonstrate that bursts of LFEs can result from the collective behavior of asperities whose interaction depends on the state of the fault interface.

A new 12R-type perovskite-related oxide, Ba 3 NdMn 2 O 9 , has been prepared by traditional solid-state reaction method and the presence of chemical phase separation phenomenon has been revealed by transmission electron microscopy. The perfect grains of the compound have an average chemical composition of Ba 4 NdMn 3 O 12 (mainly for cationic ratio) according to the characterization by TEM-EDX. In this perfect 12R-type structure with composition Ba 4 NdMn 3 O 12 , the Nd cations are located in the corner-sharing octahedra, whereas the Mn cations are located in the face-sharing octahedra, leading to a remarkable cation ordering. Superstructure modulation was found to be a common phenomenon in the 12R polytype and the modulated areas were revealed by both EDX and EELS to be Nd rich compared to the perfect areas. This result together with the previous work [A.F. Fuentes, K. Boulahya, U. Amador, J. Solid State Chem. 177 (2004) 714] has shown that, for the rare-earth-containing Ba-RE-Mn-O systems (RE being rare-earth elements), the composition Ba 4 REMn 3 O 12 (mainly for cationic ratio) is required for the formation of perfect 12R polytype

In this work, through a review of the literature, we assessed several aspects of how CP influences the patient’s daily activities and quality of life, as well as its repercussions in the workplace, and on the family and social environment. Finally, the consequences of pain on the health care system are discussed. On the basis of the results, we concluded that in addition to the serious consequences on the patient’s life, CP has a severe detrimental effect on their social and family environment, as well as on health care services. Thus, we want to emphasize on the need to adopt a multidisciplinary approach to treatment so as to obtain more comprehensive improvements for patients in familial and social contexts. Accordingly, it would be beneficial to promote more social- and family-oriented research initiatives. Keywords: pain, everyday problems, social relationships, family environment, health services

2016-01-01

This work evaluates the ashes generated from the wood and coal combustion process of the thermoelectric plant in Petacalco, Guerrero (Mexico) in order to determine its viability as a filter in the biogas purification process. The ash is constituted by particles of morphology and different chemical properties, so it required a characterization of the same by different analytical techniques: as was scanning electron microscopy and X-ray diffraction, in order to observe the microstructure and determine the elemental chemical composition of the particles. Prior to the analysis, a set of sieves was selected to classify as a function of particle size. Four different types of ashes were evaluated: one generated by the wood combustion (wood ash) and three more of the Petacalco thermoelectric generated by the coal combustion (wet fly ash, dry fly ash and dry bottom ash).

2011-02-01

A fructanase, produced by a Kluyveromyces marxianus strain isolated during the fermentation step of the elaboration process of "Mezcal de Guerrero" was purified and biochemically characterized. The active protein was a glycosylated dimer with a molecular weight of approximately 250 kDa. The specific enzymatic activity of the protein was determined for different substrates: sucrose, inulin, Agave tequilana fructan, levan and Actilight® and compared with the activity of Fructozyme®. The hydrolysis profile of the different substrates analyzed by HPAEC-PAD showed that the enzyme has different affinities over the substrates tested with a sucrose/inulin enzymatic activity ratio (S/I) of 125. For the hydrolysis of Agave tequilana fructans, the enzyme also showed a higher enzymatic activity and specificity than Fructozyme®, which is important for its potential application in the tequila industry.

Monitoring guidelines improve control of walnut husk fly in California

Opp, Susan B.; Reynolds, Katherine M.; Pickel, Carolyn; Olson, William

2000-01-01

The walnut husk fly (WHF), Rhagoletis completa Cresson, is a key pest of walnuts (Juglans spp.) in California, where over 95% of the US and approximately two-thirds of the world's commercial walnuts are produced. The primary hosts of this monophagous fruit fly are J. regia L. (commercially grown English walnut), J. californica S. Wats. var. hindsii (northern California black walnut), J. californica var. californica (southern California black walnut) and J. nigra Thunb. (eastern black walnut). Some cultivars of the English walnut are more susceptible than others; the most heavily infested varieties of English walnut include Eureka, Franquette, Hartley, Mayette and Payne. Neither English walnuts nor the walnut husk fly are native to California. So-called 'English' walnuts are sometimes more appropriately called 'Persian' walnuts, in reference to Persia, the origin of J. regia. English walnuts were first planted in southern California in the 1860s. In contrast, the native range of WHF is the mid- and south-central United States where it attacks J. nigra (Boyce 1934). The fly was likely to have been introduced into southern California in the mid-1920s by tourists travelling from Kansas, New Mexico, Texas or Oklahoma. WHF was first documented in California in 1926 in the San Bernardino County when maggots were found in the husks of English walnuts (Boyce 1929). The fly gradually spread throughout walnut growing regions of California. In 1928, only three or four orchards in the San Bernardino County were known to be infested. By 1932, the fly was also found in the Los Angeles and Orange Counties (Boyce 1933), and by 1954, it was found in Ventura, Riverside, and the San Diego Counties, in addition to the northern California county of Sonoma (Anonymous 1966). The spread of the fly in northern California was rapid. By 1958, WHF was found in San Joaquin County; in 1963, the fly was in Amador, Lake, Solano, Tulare and Yolo Counties; in 1964, it was found in Fresno, Mendocino

Full Text Available This study’s objective was to understand how occupational roles of individuals with anorexia nervosa are configured. The sample was composed of a control group and 11 adult women with anorexia nervosa being cared for by the Eating Disorders Care Group in a hospital in Ribeirão Preto, SP, Brazil. Socio-demographic and anthropometric data were collected and the Role Checklist was applied. The results revealed a significant loss of roles for women with anorexia nervosa in relation to the performance of the roles worker, friend, and amateur/hobbyist, supporting the idea that psychosocial harm may arise from this eating disorder. The evaluation of occupational roles in the treatment of eating disorders is an important strategy for planning Occupational Therapy activities and supporting the creation of healthier spaces to enable individuals to resume occupational roles, and acquire independence and autonomy.El objetivo es entender como figuran los papeles ocupacionales de las personas con anorexia nervosa.

Here, two papers are presented, which constitute the first reports of surgical procedures in Mexican children performed at the 19 th century. The two publications refer to surgical operations for the extraction of bladder stones. At that time, there was no anesthesia, so part of the description alludes to the suffering of the patients and the operative difficulties. The first case, is referred to as a lithotomy in a 17-year-old girl, performed by surgeon José Victoriano Guerrero in Guadalajara in 1822. The publication is not an academic report, but a pamphlet written as a gift to Emperor Augustin I to celebrate his ascension to the throne. The second work, is a lateral lithotomy in a 5-year-old boy, published by Dr. Luis Jecker in the first issue of the Periódico de la Academia de Medicina de Mégico in 1836.

For that purpose, the corpus of 2107 journalistic documents was explored over a period of three months, following the newspapers Reforma and La Jornada; the purpose of this exploration was to identify the discourse strategies used in the press to report on the fact, from the lexical frequency and the nominal phrasing occurrence. Four strategies were specifically identified: negation, and neutralization, which are used to hide the State responsibility in the violent acts and the historization and accreditation as part of the dissident discourse.  All of the strategies are oriented to the dispute of the lexical fields that give sense to the forced disappearance and the violation of human rights. © Revista Colombiana de Ciencias Sociales.

For a Critique of Transatlantic Mestiza Territoriality: Challenging the Angolan-Cuban Revolutionary Community

Full Text Available This essay presents the transatlantic confluence of two hegemonic cultural traditions; the ideology of mestizaje and lusotropicalismo in the discourses of the Angolan and Cuban socialist regimes. The shared political utopia during the Angolan Civil War envisioned a South-South community, racially homogeneous. In the last part of the essay I review the works Dulces guerreros cubanos (1999 by Norberto Fuentes, Desconfiemos de los amaneceres apacibles (2011 by Emilio Comas Paret, Geração da Utopía (1992 by Pepetela, and Estação das Chuvas (1996 by José Eduardo Agualusa, in order to demonstrate socio-racial conflicts embedded in the leftist armed struggle. These narratives challenge the homogeneity of official discourses about identity that sustained the transatlantic mestiza territoriality. In doing so, they note a historical continuity of inequality and authoritarianism between colonial and postcolonial, between pre-national and revolutionary nation.

Dengue, recognized by the WHO as the most important mosquito-borne viral disease in the world, is a growing problem. Currently, the only effective way of preventing dengue is vector control. Standard methods have shown limited effect, and there have been calls to develop new integrated vector management approaches. One novel tool, protecting houses with long lasting insecticidal screens on doors and windows, is being trialled in a cluster randomised controlled trial by a joint UADY/WHO TDR/IDRC study in various districts of Acapulco, Mexico, with exceptionally high levels of crime and insecurity.This study investigated the community's perspectives of long lasting insecticidal screens on doors and windows in homes and in schools, in order to ascertain their acceptability, to identify challenges to further implementation and opportunities for future improvements. This was a sequential mixed-methods study. The quantitative arm contained a satisfaction survey administered to 288 houses that had received the intervention examining their perspectives of both the intervention and dengue prevention in general. The qualitative arm consisted of Focus Group Discussions (FGDs) with those who had accepted the intervention and key informant interviews with: schoolteachers to discuss the use of the screens in schools, program staff, and community members who had refused the intervention. Overall satisfaction and acceptance of the screens was very high, with only some operational and technical complaints relating to screen fragility and the installation process. However, the wider social context of urban violence and insecurity was a major barrier to screen acceptance. Lack of information dissemination and community collaboration were identified as project weaknesses. The screens are widely accepted by the population, but the project implementation could be improved by reassuring the community of its legitimacy in the context of insecurity. More community engagement and better information sharing structures are needed.The screens could be a major new dengue prevention tool suitable for widespread use, if further research supports their entomological and epidemiological effectiveness and their acceptability in different social and environmental contexts. Further research is needed looking at the impact of insecurity of dengue prevention programmes.

In this study, we apply a liposomal melanin–fluorescein compound to an ex vivo model of human skin, using a new electrical microneedling device (Nanopore turbo roller. The product was applied by hand massage (A or with the assistance of the electrical roller for 2 minutes (B. An additional test was performed free of product and with only the E-roller (C. Histological changes and product absorption were evaluated by optical and fluorescent microscopy 60 and 90 minutes after the treatment. Site B showed larger deposits of melanin–fluorescein at superficial and deep levels of hair structures in comparison to site A. Light, epidermal deposits of the melanin–fluorescein complex were also observed. Sites B and C showed a significant widening (47% of the follicular infundibulum which could explain the increased penetration of the formulation. Microneedling also removed the scales and sebum residues in the neighborhood of the infundibulum. Targeting hair follicles with melanin may be useful to dye poorly pigmented hairs, improving laser hair removal. The procedure accelerates the delivery of melanin into hair structures allowing an even absorption, larger pigment deposits, and deeper penetration of the formulation into the hair.

Los hallazgos del Sacromonte a la luz de la historia de la Iglesia y de la teología católica

2002-12-01

Full Text Available The Lead Books, far from being a purely Moorish invention of its creators and in its ideological content, have at their base Medieval Christian traditions, a Catholic theology and the religious-political problems of modem Spain. In their origin, thinkers of a pronounced counter-reform view also actively participated. In the present state of research of the Morisco problem which goes beyond the monolithic, partisan vision of this ethnic group, it is essential to initiate new fields of interpretation of the books' contents and of the findings of Sacromonte in general. As an example, we suggest a treatment of the persons and themes fundamental to the thread of argument, as are the Apostle St. James, St. Cecil and the Virgin's inmaculate conception.

Lejos de ser sólo una fabulación netamente morisca en su inventores y en sus contenidos ideológicos, los libros plúmbeos tienen en su base las tradiciones medievales cristianas, la teología católica y la problemática político-religiosa de la España moderna; en su gestación también participaron activamente pensadores de marcado corte contrarreformista. En la línea actual de investigación del problema morisco, que supera la monolítica, partidista y radial visión de esta etnia, hay que iniciar nuevos campos de interpretación del contenido de los libros plúmbeos y de los hallazgos del Sacromonte granadino en general. Proponemos como ejemplo el tratamiento de personajes y temas tan fundamentales en el hilo argumental como son el apóstol Santiago, san Cecilio y la Concepción Inmaculada de la Virgen.

Evaluation of the properties of the CaCO3CaO system for metallurgical use

International Nuclear Information System (INIS)

Tapia, O.; Grijalva, M.; Rodriguez, A.; Formoso, A.

1999-01-01

The principal goal of this work, is to make a preliminary and comparative study on the physical chemistry, structural and thermal properties of the metallurgical lime production using experimental, and in some cases industrial measurements. This is important, because the characterization of the CaCO 3 CaO system, predicts the dissolution grade of the lime on the slag solution in the steel making. The mineral is located on the border of Michoacan (Lazaro Cardenas)and the Guerrero states (La Union) Mexico. This study evidences limited properties of this lime, which is due to the thermal and physical chemistry behaviour of the obtained results of this material. However, it is necessary to make a study in the future about the kinetic behavior during decomposition. This is necessary because it is important to obtain an increase in the basic oxides concentration and a decrease in the loss of ignition, which is important for the competitive lime production.

Policies of fear and local resistances

Directory of Open Access Journals (Sweden)

Pilar Calveiro

2015-12-01

Full Text Available In this text, I begin with maintaining that the use of fear as an instrument of population control is a constitutive element of Neoliberal governance. Also, I suggest that current violence, because of its characteristics, is more easily observable and understandable in local environments, which would explain that the most important resistances also come from these spaces. For this purpose, I analyse the case of the state of Guerrero, in México, focusing on the surge and path of the Regional Organizer of Community Authorities (Coordinadora Regional de Autoridades Comunitarias, CRAC and, more recently, in the same territory, the forceful disappearance of 43 students in Ayotzinapa and the forms of mobilization and organization that followed this tragedy. I attempt to point out the consistency in the policies of fear by public-private networks, which connect legal and illegal circuits, as well as the strategies used to overcome fear, display resistance and, mainly, build power and politics from the margins.

In vitro dialyzability of essential minerals from white and whole grain pasta.

Vignola, María Belén; Bustos, Mariela Cecilia; Pérez, Gabriela Teresa

2018-11-01

The aim of the present investigation was to study the in vitro mineral dialyzability of pasta made with white and whole-grain flours obtained from two genotypes (Klein Guerrero and Baguette Premium 11) with different mineral contents. Pasta samples were made from white flour (FP), and whole grain flour from cyclonic mill (WFAP) and blade mill (WFBP). Mineral content and in vitro digestion were determined on all samples to study starch variation and mineral dialyzability. Whole-grain pasta contained significantly higher amounts of minerals than FP, since bran and embryo are richer in minerals than endosperm. In addition to the low content of mineral composition observed in FP, the dialyzability of some minerals (Cu, Fe, Mg and Zn) was higher than whole-grain pasta even when the percentage of starch hydrolyzed after intestinal digestion was higher than FP. These results can also be useful for developing wheat-based products rich in the desired minerals. Copyright © 2018 Elsevier Ltd. All rights reserved.

Violent Brokers: Use and Organization of Force as a Business in Ayutla de los Libres

Directory of Open Access Journals (Sweden)

Miguel Ángel Berber

2017-05-01

Full Text Available The article presents a analysis of violence in Ayutla de los Libres, between 2008 and 2012.  The research is based on statistical data and more than 40 interviews. This period is characterized by the appearance of violent intermediaries:  criminal groups with the capacity to organize the use of violence as a business.  The main activities of these groups were security and protection provision, conflict resolution, and exaction.  Several factors have been present in Guerrero and Ayutla that could account for increase in the homicide rate: the federal security strategy and disputes among DTO. However, the violence in Ayutla is not explained only because of the drug trafficking and competence among DTOs. Micro-analysis can offer variations and nuances to the perspectives about violence. This text invites to elaborate more contextualized, ethnographic studies that confirm or reject the government and media narratives about violence in Mexico.

Las dos fuentes presentan diferencias significativas entre sí: el monto difiere, en promedio, en dos mil muertes anuales, lo que representa entre 15 y 20 por ciento de la cifra anual de homicidios; sin embargo, coinciden en señalar al año 2008 como un momento de repunte de este tipo de delitos en la república mexicana, particularmente en cinco entidades federativas: Baja California, Chihuahua, Durango, Guerrero y Sinaloa. Se destaca el hecho de que el incremento de homicidios se da luego de la aplicación de una estrategia gubernamental de lucha frontal contra el crimen organizado iniciada en el año 2007.

Study of time dynamics of seismicity for the Mexican subduction zone by means of the visibility graph method.

Ramírez-Rojas, Alejandro; Telesca, Luciano; Lovallo, Michele; Flores, Leticia

2015-04-01

By using the method of the visibility graph (VG), five magnitude time series extracted from the seismic catalog of the Mexican subduction zone were investigated. The five seismic sequences represent the seismicity which occurred between 2005 and 2012 in five seismic areas: Guerrero, Chiapas, Oaxaca, Jalisco and Michoacan. Among the five seismic sequences, the Jalisco sequence shows VG properties significantly different from those shown by the other four. Such a difference could be inherent in the different tectonic settings of Jalisco with respect to those characterizing the other four areas. The VG properties of the seismic sequences have been put in relationship with the more typical seismological characteristics (b-value and a-value of the Gutenberg-Richter law). The present study was supported by the Bilateral Project Italy-Mexico "Experimental Stick-slip models of tectonic faults: innovative statistical approaches applied to synthetic seismic sequences", jointly funded by MAECI (Italy) and AMEXCID (Mexico) in the framework of the Bilateral Agreement for Scientific and Technological Cooperation PE 2014-2016

Revealing the cluster of slow transients behind a large slow slip event.

Frank, William B; Rousset, Baptiste; Lasserre, Cécile; Campillo, Michel

2018-05-01

Capable of reaching similar magnitudes to large megathrust earthquakes [ M w (moment magnitude) > 7], slow slip events play a major role in accommodating tectonic motion on plate boundaries through predominantly aseismic rupture. We demonstrate here that large slow slip events are a cluster of short-duration slow transients. Using a dense catalog of low-frequency earthquakes as a guide, we investigate the M w 7.5 slow slip event that occurred in 2006 along the subduction interface 40 km beneath Guerrero, Mexico. We show that while the long-period surface displacement, as recorded by Global Positioning System, suggests a 6-month duration, the motion in the direction of tectonic release only sporadically occurs over 55 days, and its surface signature is attenuated by rapid relocking of the plate interface. Our proposed description of slow slip as a cluster of slow transients forces us to re-evaluate our understanding of the physics and scaling of slow earthquakes.

To determine non-fatal road traffic injuries (NFRTI) prevalence and its distribution in Mexico. Data from ENSANUT Survey 2006 were used. Using simple random sampling, one adult, one adolescent and one child were selected in each household, constituting a final sample of 94,197 representing an N of 102,886,482 people. The dependent variable was the prevalence of road traffic injuries (RTI) during the 12 months prior to the survey. The general accident prevalence was 6.0%; 16.7% corresponded to NFRTI. Men in the 20 to 44 age group living in urban areas and with high socioeconomic status had a higher RTI prevalence (p<0.05). Jalisco, Aguascalientes and Sonora were states with the highest prevalence of RTI, while Guerrero, Michoacan and Oaxaca were those with the lowest. NFRTI are frequent in Mexico and they are concentrated among men in productive ages in urban areas; they are associated with socioeconomic status at the individual level and with the state's development at the population level.

We recently proposed a Quantum Optimal Control (QOC) method constrained to build pulses from analytical pulse shapes [R. D. Guerrero et al., J. Chem. Phys. 143(12), 124108 (2015)]. This approach was applied to control the dissociation channel yields of the diatomic molecule KH, considering three potential energy curves and one degree of freedom. In this work, we utilized this methodology to study the strong field control of the cis-trans photoisomerization of 11-cis retinal. This more complex system was modeled with a Hamiltonian comprising two potential energy surfaces and two degrees of freedom. The resulting optimal pulse, made of 6 linearly chirped pulses, was capable of controlling the population of the trans isomer on the ground electronic surface for nearly 200 fs. The simplicity of the pulse generated with our QOC approach offers two clear advantages: a direct analysis of the sequence of events occurring during the driven dynamics, and its reproducibility in the laboratory with current laser technologies.

Marine Microbial Mats and the Search for Evidence of Life in Deep Time and Space

Des Marais, David J.

2011-01-01

Cyanobacterial mats in extensive seawater evaporation ponds at Guerrero Negro, Baja California, Mexico, have been excellent subjects for microbial ecology research. The studies reviewed here have documented the steep and rapidly changing environmental gradients experienced by mat microorganisms and the very high rates of biogeochemical processes that they maintained. Recent genetic studies have revealed an enormous diversity of bacteria as well as the spatial distribution of Bacteria, Archaea and Eukarya. These findings, together with emerging insights into the intimate interactions between these diverse populations, have contributed substantially to our understanding of the origins, environmental impacts, and biosignatures of photosynthetic microbial mats. The biosignatures (preservable cells, sedimentary fabrics, organic compounds, minerals, stable isotope patterns, etc.) potentially can serve as indicators of past life on early Earth. They also can inform our search for evidence of any life on Mars. Mars exploration has revealed evidence of evaporite deposits and thermal spring deposits; similar deposits on Earth once hosted ancient microbial mat ecosystems.

The aim is to use the Studies of the Imaginary by Gilbert Durand to look symbolic images for the photographic images. It is ended that the symbolic imagination is present also in an activity eminently technique as the picture, and that the abundance of pictures of the intimate banalities indicates a conversion of the objetictiv and warlike imaginary to an euphemistic and subjetctiv imaginary.

Although the quality of these records is poor, it is possible to estimate a temporal variation of energy in the range of 1-2Hz (best signal/noise ratio for the NVT). These clearly indicate a maximum of NVT energy release (En) during the 2001-2002 and 2006 large aseismic slow slip events (SSE) registered by the Guerrero GPS network. In particular En is higher for the 2001-2002 SSE which had larger surface displacements and extension than the 2006 SSE. A more detailed and accurate study of NVT activity was carried out using the data collected during the MASE experiment in Mexico. MASE consisted of 100 broad band seismometers in operation for ~2.5 years (2005-2007) along the profile oriented SSW-NNE from Acapulco, and crossing over the subduction zone for a distance of ~500 km. Epicenters and depths of individual tremor events determined using the envelope cross-correlation technique have rather large uncertainties, partly originated from the essentially 2D geometry of the network. The 'energy' approach is more efficient in this case because it provides an average NVT activity evolution in time and space. The data processing consists of a band pass (1-2Hz) filter of the raw 100 Hz sampled N-S component records, application a 10 min-width median filter to eliminate the effect of local seismic events and noise, and integration of the energy and normalization of daily En using an average coda amplitude from several regional earthquakes of M~5. A time-space distribution of En reveals a strong correlation between NVT energy release and the 2006 SSE, which also replicates the two-phase character of this slow event and a migration of the slow slip maximum from North to South. There are also a few clear episodes of relatively high NVT energy release that do not correspond to any significant geodetic

Full Text Available Investigou-se a prevalência de sobrepeso e obesidade e respectivos fatores associados em escolares mexicanos. O estudo teve delineamento transversal e amostra composta por 700 escolares. As prevalências de sobrepeso e obesidade foram calculadas segundo sexo e idade, e as medidas de associação (odds ratios estimadas por pontos e por intervalos, utilizando-se a regressão logística multivariada. Para o conjunto de escolares, as prevalências de sobrepeso e obesidade foram 28,1% e 13,7%, respectivamente. Os fatores de risco para o sobrepeso foram: "número de anos de escolaridade da mãe"; "hábito de comer enquanto estuda ou assiste à TV"; "escores de freqüência de consumo de alimentos de risco > 12 pontos"; "atividades sedentárias > 1,6 horas/dia" e "peso ao nascer > 2.890 gramas". Os fatores de risco para a obesidade foram semelhantes àqueles detectados para o sobrepeso. Maior freqüência de atividades esportivas foi identificada como fator de proteção para ambos os desfechos. A detecção dos principais fatores associados ao sobrepeso e à obesidade indica o direcionamento de intervenções para a prevenção de doenças crônicas nessa população, cujos fatores de risco já podem ser identificados a partir da infância.This study aimed to investigate the prevalence rates for overweight and obesity among Mexican schoolchildren, identifying factors associated with the outcomes. A cross-sectional study was conducted in a sample consisting of 700 schoolchildren. Prevalence rates were calculated according to age and gender, and odds ratios were estimated by point and intervals, using multivariate logistic regression. Overweight and obesity prevalence were 28.1% and 13.7%, respectively. Risk factors for overweight were: mother's schooling (in years; eating while studying or watching TV; scores for risk food items > 12 points; sedentary activities > 1.6 hours/day, and birth weight > 2,890 grams. Obesity risk factors were similar to those related to overweight. Higher frequency of sport activities was detected as a protective factor in both outcomes. The associated factors for overweight and obesity highlighted the focus for health programs to prevent chronic diseases in this population, for which risk factors can already be identified in childhood.

Full Text Available Twenty-five bats were trapped in Yutaje (Amazonas, Venezuela and examined for Litomosoides (Filarioidea: Onchocercidae. Of the nine recovered bat species, only Pteronotus parnelli was infected; it is a cave-dwelling species belonging to a family, Mormoopidae, which has not previously been included in the host range of the genus. The new species, L. yutajensis n. sp., has two median cephalic bosses covered with rugosities and differs from the 15 recognized species and subspecies from bats in several characters. Alike L. molossi Esslinger, 1973, L. chandleri Esslinger, 1973 and L. chitwoodi Bain, Guerrero, Rodriguez 2003 , the new species has cuticular lateral bosses on the body. Eight of 10 P. parnelli were microfilaraemic, but only three had adult worms, showing that microfilariae survive longer than adults, which could lengthen the period of transmission. No infective larvae were detected in the following macronyssid mites: 58 Ornithonyssus bacoti, Ornithonyssinae, experimentally fed on microfilaraemic bats and dissected 15 days later, and a few Radfordiella sp., Macronyssinae, recovered from P. parnelli.

To describe and compare household dynamics in terms of structure, beliefs and nutrition-related behavior in the homes of malnourished and well-nourished children less than five years of age. The authors carried out a qualitative ethnographic study using participant observation, and in depth interviews. Interviews were conducted with the child's caretaker or key informants, prior oral informed consent. Child care and childhood feeding practices at home and in the community were the focus of observations. The study included two periods of field work conducted in 2001, in three rural municipalities from the Río Balsas region, in Guerrero state, Mexico. The study's ethical and methodological aspects were approved by the National Research Commission of the Mexican Institute of Social Security. Households were differentially characterized by number of members, composition, type of relationship, source of income, and interactions among household members and with the community. Monoparental structures, in an early stage of the household cycle, give rise to conditions that render the child prone to malnutrition. Extended family structure represented more favorable household dynamics.

In the research cooperation promotion projects having been carried out, the R and D of an overall recovery system have been conducted which recovers effectively and systematically valuable resources such as magnesium, bromine and boron including in brine made after the salt manufacturing in the coastal region in Mexico. In this project, as the research on the distilling process needed for commercialization of the system to recover valuable resources from the brine, Japan has been collecting information on various distilling processes and solar pond systems and studying a distilling process appropriate to the site jointly with Mexico. As a result, a seawater desalination process which combined the solar pond using solar energy and the evaporation method was recommended as a low-priced distilling method. Moreover, it was indicated that the solar still method for condensing/recovering the evaporated water of the Guerrero Negro salt pan is also less influential in the salt manufacturing process and is viable as a most economical distilling process by studying the structural design and operational method of more efficient solar stills

Full Text Available Corridor Acapulco-Zihuatanejo is the name under the coastal plain is known, between these cities in the state of Guerrero, a strip of land located on the northwestern coast of the state which is very interesting for private investment in tourist mega-projects. This article describes the historical vicissitudes that have occurred in land use with development cycles and crises in production practices, and the consequent cultural change by successive jumps in the landscape of this territory. Using a model case study and the retrospective geography fundamentals it is possible an investigation to understand the conditions which provide a continuity of production practice or the determinant that raise a decisive break in the same practice. For this work, the landscape is a historical-cultural construction, the crop is the unity of the geographical environment which participates in the formation of the landscape within the successive production cycles, and the retrospective is a solution to questions about the future because the observation of the past suggests the question about the future, invite to leave the retrospective by the uncertainty of prospective.

Full Text Available Abstract The control over what Dillon and Lobo-Guerrero (2008 conceptualise as ‘pluripotent’ life has become an essential factor of capitalist agriculture; this occurs through the regulation of strategic genetic resources. We recognise this course as part of a larger project of neo-agro-colonialism, which takes place by controlling both biotechnology and territories as an expression of a fungible power, turning geopolitics into biopolitics and vice-versa. While assessing the power relations and manipulation of spatio-temporalities in the process of life fabrication, we discuss the mechanisms of control over ‘pluripotent’ life – genetically modified seeds and biopiracy through patentisation of traditional knowledges – which turns life into a commodified good. This is to say that the instrumental use of life fabrication within the rationale of globalised capital (recreates post-colonial temporalities that legitimise (renew(ed colonial ties.

Lomnitz, C.; Rodríguez-Padilla, L. D.; Castaños, H.

2013-05-01

Locations of 3,000 earthquakes of 40 to 300 km depth are used to define the 3-D structure of the subducted Cocos Plate under central and southern Mexico. Discrepancies between deep-seated lineaments and surface tectonics are described. Features of particular interest include: (1) a belt of moderate activity at 40 to 80 km depth that parallels the southern boundary of the Mexican Volcanic Plateau; (2) an offset of 150 km across the Isthmus of Tehuantepec where all seismic activity is displaced toward the northeast; (3) three nests of frequent, deep-seated events (80 to 300 km depth) under southern Veracruz, Chiapas and the coast of Mexico-Guatemala. The active subduction process is sharply delimited along a NW-SE lineament from the Yucatan Peninsula, of insignificant earthquake activity. The focal distribution of intermediate-depth earthquakes in south-central Mexico provides evidence of stepwise deepening of the subduction angle along the Trench, starting at 15 degrees under Michoacan-Guerrero to 45 degrees under NW Guatemala. Historical evidence suggests that the hazard to Mexico City from large intermediate-depth earthquakes may have been underestimated.

This study was conducted with the objective of determining whether there is a depuration of organochlorine pesticides in breast milk according to breastfeeding time. In total, 171 samples from mothers that lived in the State of Guerrero, Mexico were analyzed. There was a weak negative relationship between pp'DDE (r = -0.216) and Σ-DDT (r = -0.222) concentrations with the days of lactation. In a comparison analysis, a statistically significant decrease of pp'DDT and pp'DDE levels was observed, as well as the Σ-DDT from the first to the fifth week of lactation. A reduction of 0.188 mg/kg lipid of pp'DDE and 0.181 mg/kg lipid of Σ-DDT per week was obtained. HCB, β-HCH and op'DDT concentrations were low and had no major fluctuations between subgroups. The low levels found and the observed reduction in time involve less exposure to the infant to these pollutants. Through this methodology changes in levels of certain organochlorine pesticides in various stages of human milk production may be shown.

Full Text Available In 1667 the construction of the Hospice of Saints Ildefonso and Tomás de Villanueva began on the Roman Via Sistina. The headquarters of the Augustinian Recollects in Rome took on a particular architectural configuration directly inspired by Francesco Borromini’s Chapel of the Three Kings and a very concrete iconography linked to the political situation during the second half of the 17th century. Thus the church was decorated to create a monument to the Immaculate Conception with images of the Loreto litany adorning its walls, reinforced by paintings of the Virgins of Copacabana and Guadalupe inside. All of this, combined with the dedication of the building to Saint Tomás de Villanueva (canonized in 1658, turns the temple into a celebration of the pietas hispanica in an area of the Holy City scene of clashes for power between France and Spain.En 1667 se pone la primera piedra del Hospicio de los santos Ildefonso y Tomás de Villanueva en la Via Sistina romana. La sede de la orden de los agustinos recoletos en Roma toma una particular configuración arquitectónica, directamente inspirada en la Capilla de los Reyes Magos de Francesco Borromini, y una muy definida iconografía vinculada con la situación política de la segunda mitad del siglo XVII. Así, la iglesia se erige en un monumento a la Inmaculada Concepción concretado en las imágenes de la letanía lauretana que ornan sus muros y reforzado por las pinturas de las vírgenes de Copacabana y Guadalupe en su interior. Todo ello, junto a la advocación a Santo Tomás de Villanueva, canonizado en 1658, convierte el templo en un alegato a la pietas hispanica en un área de la ciudad que fue escenario de los enfrentamientos entre Francia y España.

The study of music academies is not quite known. From few works on literary academies, this article will focus on the music academy that of Juan de Borja i Castro hold in Madrid. In this way, if the courtly literary patronage is already an issue with multiple variants, the approach to other artistic activities, such as the music, it is even more. In the following pages, it will delve into the various aspects of erudition of Juan de Borja with the thread of the academies, as a centre of intellectual, creative and cultural promotion and personal. Some of the most important composers of the Iberian World of that time, such as Francisco Guerrero or Tomás Luis de Victoria, were involved in this academy.

Full Text Available Se realizaron muestreos de Amphiroa beauvoisii (Corallinales, Rhodophyta en diversas localidades de las costas del Pacífico y Caribe mexicano de 1994 a 2007 y se efectuó una extensa revisión bibliográfica de los trabajos en los que se cita Amphiroa beauvoisii. Asimismo, se revisaron los ejemplares depositados en herbarios nacionales y extranjeros, con el propósito de determinar la distribución latitudinal, y la variación morfológica y reproductiva de esta especie. El análisis de la información nos indica que se encuentra ampliamente distribuida en la costa del Pacífico desde islas Coronados, Baja California hasta La Ventosa, Oaxaca, siendo muy frecuente en el golfo de California y en los estados de Jalisco, Guerrero y Oaxaca, mientras que en la costa atlántica su distribución se encuentra restringida a los arrecifes coralinos de Yucatán y Quintana Roo. Se describen en forma detallada los caracteres morfo-anatómicos y reproductivos. En general se observó que los talos tetrasporangiales y bisporangiales son frecuentes, de mayor talla y más ramificados que las plantas gametangiales. El material examinado mostró que en la costa del Pacifico se encuentran los talos tetrasporangiales, bisporangiales y gametangiales, mientras que en la costa del Caribe mexicano sólo se presentan poblaciones tetrasporangiales. Se registra por primera vez la fase gametofitica masculina y femenina de A. beauvoisii en poblaciones mexicanas.Several samples of Amphiroa beauvoisii (Corallinales, Rhodophyta were collected in different localities along the Pacific and Caribbean coasts of Mexican from 1994 to 2007.

MATERIAL Y MÉTODOS: Estudio cualitativo con un diseño etnográfico basado en observación participante y entrevistas a profundidad a responsables del cuidado de menores e informantes clave bajo consentimiento informado verbal. El foco de observación fue el conjunto de prácticas relacionadas con el cuidado de los menores, con énfasis en las relacionadas con su alimentación, tanto al interior de los hogares como en la comunidad. Se realizaron dos estancias de campo, durante 2001, en tres comunidades rurales del Río Balsas, en el estado de Guerrero, México. RESULTADOS: Estructuras monoparentales, en etapa temprana del ciclo doméstico, generan condiciones que pueden propiciar la presencia de desnutrición de menores de cinco años. Las familias extensas representan, por su propia estructura, dinámicas domésticas más favorables. CONCLUSIONES: El problema de la desnutrición en ambientes de extrema pobreza resulta decisivamente influido por las estrategias nutricionales y las dinámicas sociales generadas en el interior de las familias.OBJECTIVE: To describe and compare household dynamics in terms of structure, beliefs and nutrition-related behavior in the homes of malnourished and well-nourished children less than five years of age.

The site effects and the source parameters, are inverted from a Fourier displacement spectra of seismograms that are corrected by geometrical spreading and regional attenuation valid for south center of Mexico(Ordaz and Singh, 1992). We used Genetic Algorithms (GA) to perform the non-linear inversion, like in the MAI method (Moya et al., 2000) . The GA have proved to produce better results than other traditional methods which are frequently trapped in a local minimum. GA is a method that mimics the evolution laws in living creatures. The best individuals reproduce and develop themselves with every generation. In our case each individual correspond to one source and the genes correspond to the source parameters. As in nature, the best source remain and are improved with each iteration. We assume that the site effect at each station are the same independently of the earthquake, because of that we can search for the combination of sources that can produce the smaller standard deviation of the estimated site effects from the different Fourier displacement earthquake spectra. Then we use the obtained site effects to generate a Fourier displacement spectra of an earthquake scenario. With this, we are able to compute the response spectra by means of random vibration theory (Reinoso et al., 1990). We apply this method to four stations located in the Acapulco City, Mexico, that recorded four earthquakes with epicenter located in the Guerrero Subduction Zone. The site effect estimated for one of the stations, called ACAZ, shows a good agreement with the estimated by Chávez-García et al. (1994) using spectral ratios between the ACAZ station and a rock reference site. Also we compare the response spectra from other earthquake, obtained by the former method and the response spectra computed using the acceleration record. We find an acceptable correlation between them. Chávez-García, J. Cuenca y M. Cárdenas (1994), "Estudio complementario de efectos de sitio en Acapulco

We have implemented a neural network of three hidden layers with 40 neurons each layer to be used as soil/rock transfer functions for two stations in Mexico City. The net was trained with supervised learning through input and output vectors of accelerations (twelve records, from five seismic events from Guerrero and Puebla, 5.8 M 7.3, and tested with three records not taken in account in the training. The results in the frequency domain are good, finding a seismic amplification between 0.2 to 5 Hz for the Lake zone. In the time domain we obtain results that are not coincident. Due to the data and the complex of the phenomena, it is necessary to apply this tool using more records for the training net, so the phenomena can be learned better through reliable database.

Full Text Available The sylvatic triatomine Rhodnius pallescens is considered to be the most important and widespread vector of Trypanosoma cruzi and Trypanosoma rangeli in Panama. However, its behavior and biological characteristics have only been partially investigated. Thus, to achieve sustainable and efficient control over Chagas disease in Panama, a better understanding of the ecology and biology of R. pallescens is essential. In this study we evaluated R. pallescens host feeding sources using a dot-blot assay, and the trypanosome infection index by PCR analysis in a Chagas disease endemic area of central Panama. It was found that in peridomestic palm trees, 20.3% of the examined bugs had fed on opossums (Didelphis marsupialis. However, we observed an increased anthropophagy (25.4% for those bugs collected inside houses. Considering the domestic and peridomestic habitats as a whole, the proportion of collected R. pallescens infected with trypanosomes was 87.4%. In the two habitats the predominant infection was with T. cruzi (80-90%. Between 47-51% of the analyzed triatomines were infected with T. rangeli. Mixed infections (40-51% were also detected. These findings provide a better basis for the implementation of a rational control and surveillance program for Chagas disease in regions where R. pallescens is endemic.O triatomíneo silvestre Rhodnius pallescens é considerado o mais importante vetor do Trypanosoma cruzi e Trypanosoma rangeli no Panamá. Entretanto, seu comportamento e características biológicas são pouco estudados. Para controlar a doença de Chagas no Panamá é necessário melhorar a compreensão dos aspectos eco-biológicos do R. pallescens. Neste estudo, investigaram-se as fontes de alimentação de R. pallescens usando dot-blot e o índice de infecção por Trypanosoma por metodologia molecular, em área endêmica da doença de Chagas na região central do Panamá. Foi observado que 20,3% dos barbeiros coletados em palmeiras peridomésticas se alimentavam de gambás (Didelphis marsupialis. Contudo, barbeiros coletados dentro das residências apresentaram antropofagia aumentada (25,4%. Considerando o ambiente doméstico e peridoméstico juntos, o percentual de R. pallescens infectados com Trypanosoma foi de 87,4 %. Nos ambientes doméstico e peridoméstico, a infecção por T. cruzi foi de 80,4% e 90%; a infecção por T. rangeli foi de 47% e 51%, respectivamente. Observou-se infecção mista em 43% dos triatomíneos coletados em ambiente doméstico e em 51% dos triatomíneos peridomésticos. Estes achados fornecem embasamento para a implementação de um controle adequado e um programa de vigilância para a doença de Chagas em regiões onde o R. pallescens é endêmico.

The World Federation of Hemophilia (WFH) 2010 World Congress held in Buenos Aires, Argentina, in July 2010, attracted more than 4,300 participants from 106 countries. This report summarizes two symposia held during the congress. The first, titled "Emerging Co-Morbidities in the Aging Hemophilia Population: Healthcare Challenges and Treatment Opportunities," chaired by Gerry Dolan, MD, and Jussara Almeida Cruz, MD, examined the co-morbidities experienced by the aging hemophilic patient population, such as cardiovascular disease, cancer, arthritis, osteoporosis, hypertension, and obesity. In addition, Bayer's products in preclinical and clinical development were reviewed, including a novel factor VIIa variant and a long-acting factor VIII molecule, i.e., one that has undergone site-specific PEGylation (attachment of polyethylene glycol [PEG] polymer chains to another molecule). The other symposium, titled "Practical Steps to Making Better Care for Hemophilia Patients a Reality," chaired by Carmen Altisent, MD, and Cesar Guerrero, RN, reviewed the steps that hemophilia caregivers can take to improve the care of their patients. Issues such as the treatment of hemarthroses, the role of the research nurse, and the management of pediatric patients transitioning to adulthood were discussed.

Full Text Available The shrimp fishery is one of the most important fisheries in the world, although the low selectivity from trawling nets has led to the capture of a large number of non-target species. Shrimp-bycatch species include a large number of fish and invertebrate species, of which fish species are the most abundant. The present study aims to determine the community structure as well as the average sizes at first maturity of the fish species from shrimp-bycatch caught from industrial fisheries in the Mexican Pacific from Sinaloa to Guerrero, from January to March 2015. The shrimp-bycatch fish diversity value was found to be 2.22. A total of 37 species of finfish were found, of which five were considered rare. The fish species with the highest Importance Value Index (IVI levels were Pseudupeneus grandisquamis, Paralichthys woolmani, Lutjanus peru and Diapterus peruvianus. The average size at first maturity was calculated for all species. Of the analysed organisms, 90% were in the juvenile stage, including species with riverine and artisanal fisheries. The present study demonstrates the risk within marine populations to different non-target species due to the poor selectivity of shrimp trawls.

We evaluated the association between four polymorphisms in the CRP gene with circulating levels of C-reactive protein (CRP), type 2 diabetes (T2D), obesity, and risk score of coronary heart disease. We studied 402 individuals and classified them into four groups: healthy, obese, T2D obese, and T2D without obesity, from Guerrero, Southwestern Mexico. Blood levels of CRP, glucose, cholesterol, triglycerides, and leukocytes were measured. Genotyping was performed by PCR/RFLP, and the risk score for coronary heart disease was determined by the Framingham's methodology. The TT genotype of SNP rs1130864 was associated with increased body mass index and T2D patients with obesity. We found that the haplotype 2 (TGAG) was associated with increased levels of CRP (β = 0.3; 95%CI: 0.1, 0.5; P = 0.005) and haplotype 7 (TGGG) with higher body mass index (BMI) (β = 0.2; 95%CI: 0.1, 0.3; P obesity and the haplotype 7 with BMI may explain how obesity and genetic predisposition increase the risk of diseases such as T2D in the population of Southwestern Mexico.

Levi-Strauss fue quien interrelacionó universalidad-naturaleza-cultura, poniendo de manifiesto que era la existencia de dicha prohibición la que posibilitaba una relación armónica naturaleza-cultura. Las relaciones entre derecho, economía y religión hacen del matrimonio una alianza social que se propone construir el grupo.

Early ADHD identification, severity assessment, and prompt treatment are essential to avoid the negative effects associated with this mental condition. The aim of our study was to develop a novel ADHD assessment instrument based on Microsoft Kinect, which identifies ADHD cardinal symptoms in order to provide a more accurate evaluation. A group of 30 children, aged 8-12 years (10.3 [SD 1.4]; male 70% [21/30]), who were referred to the Child and Adolescent Psychiatry Unit of the Department of Psychiatry at Fundación Jiménez Díaz Hospital (Madrid, Spain), were included in this study. Children were required to meet the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria of ADHD diagnosis. One of the parents or guardians of the children filled the Spanish version of the Strengths and Weaknesses of ADHD Symptoms and Normal Behavior (SWAN) rating scale used in clinical practice. Each child conducted a Kinect-based continuous performance test (CPT) in which the reaction time (RT), the commission errors, and the time required to complete the reaction (CT) were calculated. The correlations of the 3 predictors, obtained using Kinect methodology, with respect to the scores of the SWAN scale were calculated. The RT achieved a correlation of -.11, -.29, and -.37 with respect to the inattention, hyperactivity, and impulsivity factors of the SWAN scale. The correlations of the commission error with respect to these 3 factors were -.03, .01, and .24, respectively. Our findings show a relation between the Microsoft Kinect-based version of the CPT and ADHD symptomatology assessed through parental report. Results point out the importance of future research on the development of objective measures for the diagnosis of ADHD among children and adolescents. ©David Delgado-Gomez, Inmaculada

Full Text Available CONTEXTO: A performance musical requer alto nível de habilidade em diversos parâmetros, como coordenação motora, atenção e memória, o que a torna particularmente suscetível aos estados de ansiedade. Pesquisas nessa área têm avançado com a introdução de instrumentos específicos para abordar a ansiedade na performance musical, como é o caso da Kenny Music Performance Anxiety Inventory (K-MPAI. OBJETIVOS: O presente estudo teve como objetivo traduzir, adaptar e validar a K-MPAI para a língua portuguesa. MÉTODOS: Após autorização da autora, a escala K-MPAI foi traduzida e validada. A escala em língua portuguesa foi aplicada a 218 músicos de ambos os sexos, amadores e profissionais. Para a validação concorrente, foi utilizado o Inventário de Ansiedade Traço-Estado (IDATE, versão validada na língua portuguesa da State Trait Anxiety Inventory (STAI. RESULTADOS: A análise da consistência interna apresentou alfa de Cronbach = 0,957 com p < 0,001, reprodutibilidade com p = 0,378 e validação concorrente com a IDATE com alfa de Cronbach = 0,642 e p < 0,001. CONCLUSÃO: O estudo permite considerar a amostra com graus de confiabilidade e reprodutibilidade elevados, o que traduz este estudo como provindo de uma amostra não tendenciada e replicável a outras populações. A validação concorrente entre a K-MPAI e a IDATE permite inferir que ambas as escalas são comparáveis na capacidade de medir os níveis de ansiedade em musicistas.

These aspects raise concerns about the enunciative competence of this discursive practice and the autonomy of its field – mainly the relationship of its actors with sources and readers, producing other schemes of self-referentiality that engender in the world "of amateur authors". Would journalism be in the face of a dilution or dissolution of its nature? Or is there a possibility of restoration of its intermediation strength?

Full Text Available Javier Ena, Concepción Amador, Conxa Benito, Francisco PasquauHIV Unit, Hospital Marina Baixa, Villajoyosa, SpainAbstract: We reviewed the current information available on nevirapine immediate- and extended-release formulations and its role in single-dose and combination antiretroviral therapy. Nevirapine was approved in 1996 and was the first non-nucleoside reverse-transcriptase inhibitor available for the treatment of HIV-1 infection. Nevirapine has demonstrated good efficacy and a well-characterized safety profile. A major drawback is the low genetic barrier, allowing the emergence of resistance in the presence of single mutations in the reverse-transcriptase gene. This shortcoming is particularly relevant when nevirapine is administered in a single dose to prevent mother-to-child transmission of HIV-1 infection, compromising the efficacy of future non-nucleoside reverse transcriptase–inhibitor regimens. Studies published recently have probed the noninferiority of nevirapine compared to ritonavir-boosted atazanavir with both tenofovir disoproxil fumarate and emtricitabine in antiretroviral treatment–naïve patients. In 2011, a new formulation of nevirapine (nevirapine extended release that allowed once-daily dosing was approved by the Food and Drug Administration and by the European Medicines Agency. VERxVe, a study comparing nevirapine extended release with nevirapine immediate release in antiretroviral treatment–naïve patients, and TRANxITION, a study carried out in antiretroviral treatment–experienced patients who switched therapy from nevirapine immediate release to nevirapine extended release, provided data on the noninferiority of the new formulation of nevirapine compared with nevirapine immediate release in terms of efficacy and safety. Nevirapine extended release will further increase the durability and persistence of nevirapine-containing antiretroviral therapy, allowing once-daily dosing regimens.Keywords: nevirapine

Lobomycosis and lobomycosis-like diseases (LLD) (also: paracoccidioidomycosis) are chronic cutaneous infections that affect Delphinidae in tropical and subtropical regions worldwide. In the Americas, these diseases have been relatively well-described, but gaps still exist in our understanding of their distribution across the continent. Here we report on LLD affecting inshore bottlenose dolphins Tursiops truncatus from the Caribbean waters of Belize and from the eastern tropical Pacific Ocean off the southwestern coast of Mexico. Photo-identification and catalog data gathered between 1992 and 2017 for 371 and 41 individuals, respectively from Belize and Mexico, were examined for the presence of LLD. In Belize, 5 free-ranging and 1 stranded dolphin were found positive in at least 3 communities with the highest prevalence in the south. In Guerrero, Mexico, 4 inshore bottlenose dolphins sighted in 2014-2017 were affected by LLD. These data highlight the need for histological and molecular studies to confirm the etiological agent. Additionally, we document a single case of LLD in an adult Atlantic spotted dolphin Stenella frontalis in southern Belize, the first report in this species. The role of environmental and anthropogenic factors in the occurrence, severity, and epidemiology of LLD in South and Central America requires further investigation.

This study explores the genetic admixture of eight Mexican indigenous populations (Otomi-Ixmiquilpan, Otomi-Actopan, Tzeltales, Nahua-Milpa-Alta, Nahua-Xochimilco, Nahua-Zitlala, Nahua-Ixhuatlancillo, and Nahua-Coyolillo) on the basis of five PCR-based polymorphic DNA loci (LDLR, GYPA, HBGG, D7S8, GC), HLA_DQA1, and the blood groups ABO and Rh (CcDEe). Among the indigenous populations, the highest gene frequencies for O and D were 0.9703 and 1.000 for Zitlala (State of Guerrero) and 0.9955 and 0.9414 for Tzeltales (State of Chiapas), respectively. Maximum likelihood estimates of admixture components yield a trihybrid model with Amerindian (assuming that Nahua-Zitlala is the most representative indigenous population), Spanish, and African ancestry with the admixture proportions: 93.03, 6.03, and 0.94 for Tzeltales, and 28.99, 44.03, and 26.98 for Coyolillo. A contribution of the ancestral populations of Ixhuatlancillo, Actopan, Ixmiquilpan, Milpa-Alta, and Xochimilco were found with the following average of admixture proportions: 75.84, 22.50, and 1.66. The findings herein demonstrate that the genetic admixture of the Mexican indigenous populations who at present speak the same Amer-Indian language can be differentiated and that the majority of them have less ancestral indigenous contribution than those considered as Mestizo populations.

Full Text Available Genetic structure of the populations of H. inornata was evaluated and the barriers for genetic flux and historic processes were investigated. Samples were collected trying to cover the distribution range of the species, from Mexico to northern Perú. Based on COI sequences, 118 haplotypes from 220 specimens were detected; the differences between such haplotypes were due to 97 variable sites (21.41% of the 453 bp sequenced. A high haplotype diversity (h=0.979 and a moderate nucleotidic diversity were observed. The values of Fst, the exact test of population differentiation, and the molecular variance analysis (AMOVA were used in order to analyze the genetic differentiation. These analyses suggest the existence of two populations: northern, off the coasts of Sinaloa, Jalisco, Michoacán, Guerrero, and Oaxaca, and southern, off the coasts of Chiapas, El Salvador, Panamá and Perú. Historic events and oceanographic patterns may be the main factors determining dispersion and structure of Hi populations. It seems probable that the original population have extended first in the south and then northern. Besides, the split between these two populations may be due to several tectonic and oceanographic events constituting a barrier for H. inornata settling.

Esta investigación busca subsanar tal carencia al estudiar de manera detallada la candidatura de Pedraza desde la publicación imparcial Águila Mejicana. Específicamente, procura dar una respuesta a la pregunta: ¿cuáles fueron los argumentos periodísticos de los partidarios de Pedraza? De esta forma, analiza editoriales, colaboraciones y folletos para lograr una reconstrucción de la discursiva pedracista. Igualmente, presenta la crítica a los opuestos yorkinos, además de algunos debates suscitados entre ambos grupos. Discute los rasgos principales que la coalición pedracista resaltó sobre la idoneidad de la figura detrás de la Secretaría de Guerra y Marina (eficiencia y severidad gubernativa, imparcialidad y “hombría de bien”. Finalmente, explica por qué la alianza eligió justamente estos aspectos para confrontarse con los adversarios y, por otro lado, de qué forma estos permanecieron vigentes después de la victoria pírrica de Vicente Guerrero.

Full Text Available Desde 1945, la mayoría de los conflictos armados tuvieron lugar entre Estados y rebeldes o entre grupos armados no estatales al interior de Estados frágiles o fallidos. En la actualidad, los dramas en Irak, Siria y en Ucrania nos muestran que la guerra civil es uno de los males más importantes de nuestro tiempo. Reconociendo este hecho, el Derecho del conflicto armado no internacional, en particular desde la primera mitad de los años 90, ha experimentado un desarrollo bastante tormentoso. Este desarrollo legal tiene dos caras como la cabeza de Jano: por un lado, está caracterizado por la humanización del Derecho de los conflictos armados no internacionales. Sin embargo, por otro lado, las reglas que gobiernan las conductas en hostilidades se han cristalizado, y su denominación como ‘humanitaria’ no deja de ser eufemística. Vale la pena preguntar si el desarrollo de la ley de conflictos armados no internacionales debe complementarse con un Derecho contra el conflicto armado no internacional. La controversia presente sobre una política legal acerca del privilegio del combatiente para guerreros no estatales debe desenvolverse bajo esta nueva luz.

Full Text Available La agrupación de personas en escenarios públicos puede producir vibraciones que generan incomodidad y, en algunas ocasiones, daños a la estructura. Entre las estructuras más vulnerables a esta excitación se encuentran las tribunas de los estadios de fútbol. Por este motivo se diseñó y construyó una tribuna con parámetros dinámicos similares a la tribuna sur del Estadio Olímpico Pascual Guerrero de Cali-Colombia, para representar a escala natural el efecto de las barras bravas al saltar coordinadamente sobre la gradería. En el trabajo descrito en este artículo se utilizó un actuador electromagnético con 13,2 kg de masa móvil y una estrategia de control activo para disminuir las vibraciones producidas por la interacción Humano/Estructura. La estructura junto con el controlador fueron modelados, identificados y validados experimentalmente. El desempeño del sistema de control se verificó en simulación y su estabilidad y robustez se comprobaron con ensayos experimentales con personas con una masa total hasta 232 kg. En los ensayos experimentales el sistema de control disminuyó la respuesta hasta en un 50% de los valores sin control.

To estimate WTP we applied Contingent Valuation Method (MVC. It allows revealing the amount of money people is willing to pay in order to maintain the well-being that produces the modification in the conditions of supply of an environmental good without price in the market. The population interviewed perceives that the water of the river is polluted and the benefits they used to obtain have reduced. It is the reason why they have changed his use. Results show that inhabitants are willing to contribute resources to improve the quality of the water flow. Variables age, schooling, number of members of the household and income are statistically significant at 95% confidence and they fit very well a Tobit linear model. In terms of public policy, results show feasibly to start up an intervention to reduce water pollution with the involvement of organized people from the communities of the studied region.

Women have always had a hard time in the history of medicine; Dr. Isabel Blackwell was the first woman in history to practice medicine. Dr. Diana Beck became the world´s first female neurosurgeon. The first Latin American female neurosurgeon was Dr. María Cristina García Sancho y Álvarez-Tostado. All of these women had to face a large number of social, cultural, and economic obstacles in their path; however, this situation has changed gradually. Dr. Ana Lilia Siordia Karam was the first neurosurgeon to graduate from INNN. Nineteen years later the second female neurosurgeon at this institute was Dr. María Petra Herrera Guerrero. During their time at this institute they endured a lot of difficulties, especially with most of their coworkers; however, some coworkers treated them with respect and no gender distinction. Nowadays, four of the 25 total neurosurgery residents at INNN are women, and even though some of them have had to endure acts of gender discrimination, the general situation has changed. With work and respect, women have managed to have a larger role in the surgical field. We hope that in the near future a gender discrimination-free environment will be achieved in medicine and its specialties.

Overproduction or slow clearance of Aβ initiates a cascade of pathologic events that may lead to formation of neurofibrillary tangles, neuronal cell death, and dementia. Although immunotherapy in animal models has been demonstrated to be successful at removing plaques or prefibrillar forms of Aβ, clinical trials have yielded disappointing results. The lack of substantial cognitive improvement obtained by targeting Aβ raises the question of whether or not this is the correct target. Another important pathologic process in the AD brain is tau aggregation, which seems to become independent once initiated. Recent studies targeting tau in AD mouse models have displayed evidence of cognitive improvement, providing a novel therapeutic approach for the treatment of AD. In this review, we describe new advances in immunotherapy targeting Aβ peptide and tau protein, as well as future directions.Keywords: immunotherapy, Alzheimer's disease, β-amyloid, tau

Full Text Available México se consternó una vez más en septiembre de 2014 tras la noticia de los desaparecidos de Ayotzinapa –43 de ellos–, todos de la Escuela Normal Rural del Estado de Guerrero, al sur de la Ciudad de México. Las redes sociales, ya utilizadas en movimientos como #YoSoy132, fueron testigos del reclamo de los mexicanos. Siendo Twitter la red más utilizada para manifestar el reclamo de los usuarios al Gobierno Mexicano porque los devolvieran vivos. En este artículo, mostramos el resultado del estudio de un amplio corpus de tuits #Ayotzinapa en torno a la tragedia. Asimismo, estudiamos en particular las etiquetas constitutivas del joven género discursivo, cuyo anonimato, minimalismo y velocidad comunicativa, pueden revelar algunas facetas de las críticas más fuertes hechas al gobierno. Nuestra hipótesis se basa en que a partir de la popularidad en el uso de hashtags asociados hay una evolución de estos con el fin de llegar a una mayor audiencia. Nuestras conclusiones muestran que es necesaria una transformación de las etiquetas, con el paso del tiempo, para permanecer en la red social.

Full Text Available Esta investigación se propone determinar el impacto del incremento de la violencia en las movilizaciones actuales desde el estado de Guerrero en México y en la zona conurbada de San Salvador y La Libertad en El Salvador, durante la década del 2000. Los migrantes aquí estudiados no forman parte de los flujos tradicionales, comúnmente relacionados con precariedad laboral y económica, sino que se ven obligados a salir por la inseguridad. Se utilizó el enfoque cualitativo, aunque las cuestiones de seguridad constituyeron un reto para la construcción del instrumento y para el contacto con los sujetos de estudio. Se optó por entrevistas semiestructuradas a personas afectadas por la violencia y a personal que trabaja y ayuda a esta población. Para esto se contó con apoyo del Comité de Familiares de Desaparecidos en México (Cofamide, la Procuraduría de Derechos Humanos de El Salvador y la Universidad José Simeón Cañas (UCA, y con el Centro Regional de Defensa de Derechos Humanos José María Morelos y Pavón y Médicos Sin Fronteras, en México.

The sub-criteria values were standardized, weighted, and ordered by importance in a pairwise comparison matrix; the model was mathematically integrated to quantify the degree of extinction risk for each of the 29 populations present in the study area. The results indicate diverse levels of risk for the populations, ranging from very low to very high. Estanzuela, Presa Jaramillo, Peñas Cargadas and Plan del Baile populations have very low risk, with values less than 0.25. On the other hand, Vicente Guerrero, Morán, Minatitlán, La Garita and Tonalapa populations have very high risk (>0.35 because they are heavily influenced by anthropogenic (close to roads and towns, ecological (presence of exotic species and little or no natural regeneration and genetic (presence of mature to overmature trees and geographic isolation factors. In situ conservation activities, prioritizing their implementation in populations at most risk is highly recommended; in addition, germplasm collection for use of assisted gene flow and migration approaches, including artificial reforestation, should be considered in these locations.

Some microalgae are economically important in Mexico and the world because they can be potentially toxic. Algal explosive population growths are named harmful algal blooms and are frequently recorded in Mexico. The authors set up potentially toxic microalgae cultures from the Gulf of Mexico (Garrapatas tideland, Barberena river, Carpintero lagoon in Tamaulipas State; Chalchoapan and Catemaco lakes in Veracruz State), from the Mexican Pacific Ocean, Guerrero, Colima and Michoacán States, and from interior water bodies such as Vicente Aguirre dam, Chapultepec lake and several waste water treatment plants. This research is about the diversity and abundance of phytoplankton in relation a specific site because of harmful algal bloom events. Microalgae cultures are useful in order to solve taxonomic problems, to know life cycles, molecular studies, for the study of toxic species, and the isolation of useful metabolites. The cultures for this research are clonal, non-axenic, semi-continuous, 12:12 light/dark photoperiod, 20 ± 1 °C temperature and 90.5 µmol m(-2)s(-1) illumination. Four different culture media were used. This collection is open to the worldwide scientific community as a source of organisms in controlled conditions that can be used as a useful tool for microalgae research work.

[Abstract painting, a mental esthetic construction without exact correspondence with reality (José Guerrero: manuel and corporal expressions in his paintings)].

Science.gov (United States)

Portera Sánchez, Alberto

2006-01-01

It is desirable that a truthful aesthetic experience should be the consequence of a complete observation detached from all sorts of commercial, social, political or cultural ties. If during this period of admiration of a work of art a personal concentration is reached, the admirer perceives a liberation from all sorts of limiting ties and a rewarding artistic feeling. A similar type of mental freedom must be reached by the artist and prevail during the process of creation which must reach its greatest dimension in abstract paintings because not being illustrations they demand from the spectator a well developed habit to detect its esthetic values, difficult to perceive because they are in the abstract order. The dimensions such as perspective, symmetry, lights and shadows, usually integrated in figurative paintings to create well defined tridimensional spaces are not included in abstractions because this type of geometrical composition is not needed. In contemporary abstraction the design itself has lost its formal meaning and its protagonist role. It is frequently replaced by abrupt gestures as it is the case in the styles named "action painting" (Jackson Pollack) or "abstract expressionism" (Antonio Saura). Other abstract painters close to "minimalism" simply drop the colors on the canvas without any attempt to design but full of aesthetic energy and even single colors uniformly bathe the surface of the linen (Rothko). Other american artists of the sixties (Monis Louis) are also to be admired. They allow that the deposited and sliding colors themselves initiate and finish interesting artistic compositions. They become esential creative agents in the painting without being forced to be figurative nor to follow the creative will of the artist who, is simply acting as the first observer and only intervenes "a posteriori" accepting or rejecting the results. Only the colors and under the single influence of their sliding density create the shapes and artistic ensembles where there are still perceived their slow original movements. The observers of these abstract styles must initiate a process of perception without specific norms and wait until the engaging game of the colors generate emotional rewards in their minds such as amazement or interest that invite them to continue their tuning with the painting. If these artistic attraction is not evoked, the observer must be sadly satisfied with a simple ocular vision of the painting and again wait until the mental perception participates and the aesthetic reward is completed. What the "eyes of the mind" see is not a copy of the painting. A mental copy would not include the artistic meaning that the work of art contains which only emerges during the mental aesthetic encounter between the painting and the observer.

Cine, literatura y mito: Don Quijote en el cine, más allá de la adaptación

Pardo García, Pedro Javier

2011-04-01

Full Text Available This paper discusses Don Quixote’s presence in film, but in terms of the myth rather than the book, an approach which goes beyond adaptation and opens up the field of study in a significant way. In so doing it proposes a tentative but coherent description of the quixotic myth or narrative pattern as that of the inadequate and romantic imitator/reader of fiction, which is the point of departure for the elaboration of an initial corpus of quixotic movies. The protagonists of these films are frustrated imitators of cinematographic models, female Quixotes who romanticize reality and heroes who are Quixotic because they are not fit for the heroic task they have undertaken. In order to illustrate this deep penetration of the myth into the cinematic medium, a recent example in Spanish cinema will be examined, The Heart of the Warrior (El corazón del guerrero, 2000, a film directed by Daniel Monzón, where these several varieties are at work in a combined and crystal clear way. Our survey will allow us to make a series of distinctions which organise and structure the different kinds of relationship between Don Quixote and film (Cervantean, quixotic and quixotish film and, finally, to draw a series of theoretical conclusions which can be applied to the comparative study of film and literature.

Re-Evaluating the Geological Evidence for Late Holocene Marine Incursion Events along the Guerrero Seismic Gap on the Pacific Coast of Mexico.

Thomas A Bianchette

Full Text Available Despite the large number of tsunamis that impact Mexico's Pacific coast, stratigraphic studies focusing on geological impacts are scanty, making it difficult to assess the long-term risks for this vulnerable region. Surface samples and six cores were taken from Laguna Mitla near Acapulco to examine sedimentological and geochemical evidence for marine incursion events. Sediment cores collected from behind the beach barrier are dominated by intercalated layers of peat and inorganic sediments, mostly silt and clay, with little or no sand. Sand- and shell-rich clastic layers with high levels of sulfur, calcium, and strontium only occur adjacent to the relict beach ridge remnants near the center of the lagoon. With the exception of one thin fine sand layer, the absence of sand in the near-shore cores and the predominance of the terrigenous element titanium in the inorganic layers, evidently eroded from the surrounding hillslopes, suggests that these large-grained intervals do not represent episodic marine incursions, but rather were likely formed by the erosion and redeposition of older marine deposits derived from the beach ridge remnants when water levels were high. These results do not support the occurrence of a large tsunami event at Laguna Mitla during the Late Holocene.

Full Text Available Depicted arms and armour became particularly widespread in the Augustan period, when the Prince’s veterans tended to emphasise their role in the consolidation of the Empire with the adoption of these war themes in their tombs. The comparison between some funerary reliefs from Italy, the so-called Lusitanian Warriors, and some monetary emissions from the Iberian Peninsula, together with a recent finding in the Forum of Augustus, allows for the hypothesis that the celebration of Augustan victories in this region could have significantly contributed to the repertoire of depicted weapons that celebrated the new Empire.Las armas representadas en bajorelieve fueron particularmente generalizadas en la época de Augusto, cuando los veteranos del príncipe tendido a enfatizar su importancia en la consolidación del imperio con la adopción de estos temas de guerra en sus tumbas.

A Modeling Comparison of Methanogenesis from Noncompetitive vs Competitive Substrates in a Simulated Hypersaline Microbial Mat

Decker, K. L.; Potter, C.; Hoehler, T.

2005-12-01

The well-documented assumption about methanogens that co-occur in hypersaline mat communities with sulfate-reducing bacteria (SRB) is that they rely entirely on non-competitive substrates for methanogenesis. The reason for this is that during sulfate reduction, sulfur-reducing bacteria efficiently utilize H2, leaving a concentration too low for methanogenesis. Early results from recent work on a hypersaline microbial mat from salt evaporation ponds of Guerrero Negro, Baja, Mexico cast doubt that methanogenesis only occurs via non-competitive substrates, because it shows an excess of H2 in the mat rather than a paucity. We explore the use of our simulation model of the microbial biogeochemistry of a hypersaline mat (named MBGC) to compare methane production rates in a 1 cm thick mat when the methanogens use competitive substrates versus noncompetitive substrates. In the `non-competitive substrate' version of the model, methanogens rely exclusively on methylated amines that are accumulated as compatible solutes in cyanobacteria and released after lysis. In contrast, the `competitive substrate' models examine methanogen use of substrates (such as H2 + acetate) with different SRB population sizes (from absent to low). The comparison of these models of methane and sulfide biogeochemistry of a hypersaline mat has both ecological and geobiological significance, as one hypothesis of Archean microbial mats is that they existed in a low sulfate environment.

We studied the production system of Agua Chile, using the technique of structured interview,information was obtained that allowed us to determine and meet the current models of socio-economic benefits in the form of productionof this vegetable. The importance of this study is that the chile de agua despite being a highly profitable crop has been little studied, so it is not known the extent that can have, there are markets that offer potentially greater benefits to farmers, therefore it is important to know the current situation of farmers in order to provide alternatives to improve their economic situation. The results indicate that according to the practices of peasant production and the low level of technology that includes the type of fertilizers, agrochemicals to combat pests and diseases and low use of agricultural machinery, yields of 3.97 t ha-1 allow total revenues are higher than the costs of production. Besides the existence of limited marketing networks (primarily in local markets and in the Oaxaca city, is a competitive crop in terms of profitability for finance of small production units and furthermore, it is growing factor relevant food security of farming families.

Quizá ello sea debido a la opinión generalizada de que la condición confesional del derecho islámico lo hacía poco apto para influenciar al cristiano de la Reconquista; a pesar de ello en más de una ocasión estudiosos de diferentes disciplinas han descubierto y señalado concomitancias reveladoras entre ambos derechos, y aun cuando éstas hayan sido puestas de relieve para ilustrar un ejemplo, o utilizadas como detalle erudito o anecdótico, la verdad es que esas similitudes en las costumbres y los usos guerreros de ambas comunidades, sancionadas por el derecho, poco han servido al especialista o al estudioso de las sociedades medievales peninsulares, en vista de que no existe un estudio sistemático acerca de dichos aspectos, estudio que, por otra parte, se echa en falta, tanto más palmariamente, cuanto que los musulmanes militar y políticamente son el otro componente esencial del medievo hispano.

Cladosporium cladosporioides and Cladosporium pseudocladosporioides as potential new fungal antagonists of Puccinia horiana Henn., the causal agent of chrysanthemum white rust.

David Eduardo Torres

Full Text Available Puccinia horiana Hennings, the causal agent of chrysanthemum white rust, is a worldwide quarantine organism and one of the most important fungal pathogens of Chrysanthemum × morifolium cultivars, which are used for cut flowers and as potted plants in commercial production regions of the world. It was previously reported to be controlled by Lecanicillium lecanii, Cladosporium sphaerospermum, C. uredinicola and Aphanocladium album, due to their antagonistic and hyperparasitic effects. We report novel antagonist species on Puccinia horiana. Fungi isolated from rust pustules in a commercial greenhouse from Villa Guerrero, México, were identified as Cladosporium cladosporioides and Cladosporium pseudocladosporioides based upon molecular analysis and morphological characters. The antagonism of C. cladosporioides and C. pseudocladosporioides on chrysanthemum white rust was studied using light and electron microscopy in vitro at the host/parasite interface. Cladosporium cladosporioides and C. pseudocladosporioides grew towards the white rust teliospores and colonized the sporogenous cells, but no direct penetration of teliospores was observed; however, the structure and cytoplasm of teliospores were altered. The two Cladosporium spp. were able to grow on media containing laminarin, but not when chitin was used as the sole carbon source; these results suggest that they are able to produce glucanases. Results from the study indicate that both Cladosporium species had potential as biological control agents of chrysanthemum white rust.

Interior-exterior connection in architectural design based on the incorporation of spatial in between layers. Study of four architectural projects

Full Text Available Different spatial layers in the architectural structure of a building can create particular spatial relations and an architectural space that cannot be defined as an inner space or as an outer space, but one which has the characteristics of both. This space, which can be called “in between space”, appears as the result of a specific design concept in which the architectural composition is created by gradual insertion of volumes one inside another, like a box that is placed inside a box, inside of which is placed another smaller box and so on. The incorporation of various layers in the spatial arrangement of volumes in certain architectural compositions can be conceived as a possible approach in connecting the interior and exterior. This kind of conceptual design distinguishes itself from the common approach by its specific architecture that offers richness, variety, complexity and unique perception of space, thereby increasing its value. The paper investigates this particular concept through the analysis of four residential houses (Villa Le Lac by Le Corbusier, Solar House by Oswald Mathias Ungers, House N by Sou Fujimoto and Guerrero House by Alberto Campo Baeza, and it strives to find out the concept’s use and advantages, all with the aim of opening up new possibilities in the design of buildings and enriching the design process.

Full Text Available Objective. We evaluated the association between four polymorphisms in the CRP gene with circulating levels of C-reactive protein (CRP, type 2 diabetes (T2D, obesity, and risk score of coronary heart disease. Methods. We studied 402 individuals and classified them into four groups: healthy, obese, T2D obese, and T2D without obesity, from Guerrero, Southwestern Mexico. Blood levels of CRP, glucose, cholesterol, triglycerides, and leukocytes were measured. Genotyping was performed by PCR/RFLP, and the risk score for coronary heart disease was determined by the Framingham's methodology. Results. The TT genotype of SNP rs1130864 was associated with increased body mass index and T2D patients with obesity. We found that the haplotype 2 (TGAG was associated with increased levels of CRP (β=0.3; 95%CI: 0.1, 0.5; P=0.005 and haplotype 7 (TGGG with higher body mass index (BMI (β=0.2; 95%CI: 0.1, 0.3; P<0.001. The risk score for coronary heart disease was associated with increased levels of CRP, but not with any polymorphism or haplotype. Conclusions. The association between the TT genotype of SNP rs1130864 with obesity and the haplotype 7 with BMI may explain how obesity and genetic predisposition increase the risk of diseases such as T2D in the population of Southwestern Mexico.

Full Text Available Este artículo analiza la representación social que construyen niños de pueblos afromexicanos sobre lo negro o las personas “negras” y examina de qué manera se asocia al racismo. Los resultados se basan en el trabajo de campo realizado en la región con la mayor concentración de localidades afrodescendientes en México, la Costa Chica de Guerrero y Oaxaca, en la cual se desarrollaron diversas estrategias etnográficas con niños de cuatro a catorce años de edad, como entrevistas grupales, talleres de radio y pintura, entre otras. Después de la introducción, se presenta una explicación sobre el contexto en que se realizó la investigación. Posteriormente se exponen los principales elementos de la representación social de niños de localidades afromexicanas sobre lo negro, mostrando en qué medida se vincula al racismo, aunque sin dejar de lado otros aspectos fundamentales como su relación con la construcción social de lugar. Finalmente, se presentan pautas metodológicas para combatir el racismo. Este trabajo busca contribuir a las discusiones antropológicas sobre el racismo a partir de perspectivas teóricas y propuestas metodológicas interdisciplinarias.

Until recently the music of Rodrigo de Ceballos (ca. 1525/30–1581) had been largely ignored by musicologists under the assumption that most of it was lost or preserved in deteriorated manuscripts. Research by the musicologist Robert Snow proved this assumption wrong and placed the composer among important figures of Spanish music during the sixteenth century. Ceballos’s style is influenced by the music of two major Spanish composers of the sixteenth century, Cristóbal de Morales (1500–1553) a...

Full Text Available Abstract Background The follow-up survey of a cluster-randomised controlled trial of evidence-based community mobilisation for dengue control in Nicaragua and Mexico included entomological information from the 2012 rainy and dry seasons. We used data from the Mexican arm of the trial to assess the impact of the community action on pupal production of the dengue vector Aedes aegypti in both rainy and dry seasons. Methods Trained field workers inspected household water containers in 90 clusters and collected any pupae or larvae present for entomological examination. We calculated indices of pupae per person and pupae per household, and traditional entomological indices of container index, household index and Breteau index, and compared these between rainy and dry seasons and between intervention and control clusters, using a cluster t-test to test significance of differences. Results In 11,933 houses in the rainy season, we inspected 40,323 containers and found 7070 Aedes aegypti pupae. In the dry season, we inspected 43,461 containers and counted 6552 pupae. All pupae and entomological indices were lower in the intervention clusters (IC than in control clusters (CC in both the rainy season (RS and the dry season (DS: pupae per container 0.12 IC and 0.24 CC in RS, and 0.10 IC and 0.20 CC in DS; pupae per household 0.46 IC and 0.82 CC in RS, and 0.41 IC and 0.83 CC in DS; pupae per person 0.11 IC and 0.19 CC in RS, and 0.10 IC and 0.20 CC in DS; household index 16% IC and 21% CC in RS, and 12.1% IC and 17.9% CC in DS; container index 7.5% IC and 11.5% CC in RS, and 4.6% IC and 7.1% CC in DS; Breteau index 27% IC and 36% CC in RS, and 19% IC and 29% CC in DS. All differences between the intervention and control clusters were statistically significant, taking into account clustering. Conclusions The trial intervention led to significant decreases in pupal and conventional entomological indices in both rainy and dry seasons. Trial registration ISRCTN27581154 .

Full Text Available Este trabalho analisa a formação de uma sensibilidade barroca em Minas Gerais a partir da orientação participativa e altamente emotiva das festas coloniais, cujo legado se mantem presente nas festas religiosas de muitas antigas cidades mineradoras do estado. Enfocando as celebrações da Semana Santa na cidade sul-mineira de Campanha, o texto mostra como este evento anual era organizado pela Irmandade do Santíssimo Sacramento, passando então às mãos de uma comissão local após a extinção da irmandade. Se até meados do século XIX, havia músicos semi-profissionais contratados para tocar e cantar nas celebrações, a música foi assumida progressivamente por grupos de amadores. Assim, a festa passou a ser entendida como uma produção local e a cada ano a população renova o seu orgulho campanhense, ao contemplar sua capacidade de produzir um evento tão 'maravilhoso'.This paper analyses the formation of a baroque sensibility in the State of Minas Gerais (Brazil that derives from the participatory and highly emotive orientation of the colonial festivals, the legacy of which is still present in many former mining towns in the region. By focusing upon the Holy Week celebrations in Campanha, a small town in southern Minas Gerais, the text shows how this annual event was organized by the Confraternity of the Holy Sacrament, but was then transferred to a local committee after the confraternity was made extinct. If up to the mid 19th century there were semi-professional musicians to perform for the celebrations, responsibility for the music was slowly taken over by amateur groups. In this way the festival came to be understood as a local affair, and each year the population renews its pride in itself for its capacity to stage such a 'marvelous' event.

Full Text Available INTRODUÇÃO: Apesar de a prática regular de exercício físico reduzir o risco de doença cardiovascular, estudos recentes têm documentado elevações em biomarcadores relacionados com danos cardíacos após exercícios prolongados em indivíduos aparentemente saudáveis. OBJETIVO: Investigar as alterações nos níveis de brain natriuretic peptide (BNP e troponina T cardíaca (cTnT em atletas amadores após uma maratona, assim como verificar as possíveis relações entre as alterações, antes e depois da prova, apresentada pelos dois biomarcadores e variáveis do teste cardiopulmonar. MÉTODOS: Estudamos 38 atletas do sexo masculino (40,9 ± 6,29 anos antes e depois da Maratona Internacional de São Paulo, SP, Brasil. Foram realizadas coletas de sangue na veia antecubital para mensurar os biomarcadores cardíacos, cTnT e BNP 24h antes, imediatamente após e 24h após a maratona. Foi realizado teste cardiopulmonar máximo nas três semanas que antecederam a prova. RESULTADOS: Os valores de BNP e cTnT aumentaram imediatamente após a maratona (p<0,001 quando comparados com os valores basais. No terceiro momento (24h os valores de troponina tiveram uma redução significativa caracterizando um retorno aos valores basais. Não encontramos correlação entre idade e variáveis referentes a intensidade da maratona, porém encontramos correlação dos biomarcadores com o tempo de conclusão da maratona. CONCLUSÃO: Diferentes causas de liberação podem ser assumidas para cTnT e BNP e, neste caso, parecem não refletir dano miocárdico devido ao comportamento da curva destes marcadores, além de não haver relação entre a liberação dos dois biomarcadores.

Full Text Available O estudo, inicialmente, apresenta a inserção do esporte nos tempos modernos com o objetivo de resgatar e discutir a estruturação da produção do esporte de alto rendimento no Brasil. A modalidade vôlei de praia serviu de modelo empírico e procurou-se verificar, durante o levantamento dos dados coletados, a forma e os valores que predominavam no ambiente social em que se desenvolvia essa modalidade. Para isso, foram focalizadas as relações que se processavam no decorrer de sua estruturação e procurou-se verificar o grau de influência que elas sofreram diante das mudanças estruturais capitalistas e de novas situações conjunturais. Concluiu-se que o vôlei de praia brasileiro, na verdade, mesmo apresentando problemas inerentes à própria condição de esporte de alto rendimento, e diante das muitas adversidades que enfrenta no cenário social nacional, tem ocorrido com base nos valores ditados pelo "profissionalismo", suplantando os valores de uma cultura "amadorística" e tradicional, predominante no universo esportivo nacional.The study examines sports in modern times. The objective of this was to retrieve and discuss the structuring of high performance sports production in Brazil. Beach volleyball served as a model. During the data collection process, aim was made to ascertain the forms and values that are predominant in the social environment of beach volleyball. For this, focus was placed on the relationships that developed during the structuring process and attempt was made to verify how such relationships were influenced by the capitalist-structural changes and the new settings that resulted therefrom. The study concluded that despite having problems that are inherent to the sport's being highly performance-oriented, and in light of many adversities faced in the national scenario, Brazilian beach volleyball is based on the values dictated by professionalism that overcome values of the amateur-like and traditional culture that

Full Text Available The goal of mechanistic case diagraming (MCD is to provide students with more in-depth understanding of cause and effect relationships and basic mechanistic pathways in medicine. This will enable them to better explain how observed clinical findings develop from preceding pathogenic and pathophysiological events. The pedagogic function of MCD is in relating risk factors, disease entities and morphology, signs and symptoms, and test and procedure findings in a specific case scenario with etiologic pathogenic and pathophysiological sequences within a flow diagram. In this paper, we describe the addition of automation and predetermined lists to further develop the original concept of MCD as described by Engelberg in 1992 and Guerrero in 2001. We demonstrate that with these modifications, MCD is effective and efficient in small group case-based teaching for second-year medical students (ratings of ~3.4 on a 4.0 scale. There was also a significant correlation with other measures of competency, with a ‘true’ score correlation of 0.54. A traditional calculation of reliability showed promising results (α =0.47 within a low stakes, ungraded environment. Further, we have demonstrated MCD's potential for use in independent learning and TBL. Future studies are needed to evaluate MCD's potential for use in medium stakes assessment or self-paced independent learning and assessment. MCD may be especially relevant in returning students to the application of basic medical science mechanisms in the clinical years.

Evidence regarding the influence of the mind on the body is abundant. Several mind-body healing procedures are currently being used, among them hypnosis, biofeedback, meditation, visualizations, management of emotions and prayer. Since the Big Bang, we are entangled with everything. This interaction would let individuals to communicate with the minds and bodies of others. The field of parapsychological research has provided a lot of information about significant events, including apparitions, communications with the dead, near-death experiences and out of the body experiences. It looks apparently evident, that consciousness can persist in the absence of brain function. According to the model that assumes that it is consciousness and not matter, the base of everything that exists, what survives after death is the "quantum monad" or spirit. It is said that spiritual cures are practiced by discarnate physicians who diagnose and prescribe conventional treatments, but very often they use unknown procedures based on the management of energy fields that are currently being studied by many physicists. Representative examples of the practice of spiritual medicine were the mediums Ze Arigo, George Chapman, Barbara Guerrero (Pachita) and presently the Brazilian medium John of God. Case reports of paranormal phenomena observed and studied by honest and serious scientists are very important for the advancement of parapsychology, because it has not been clearly established which approach, the qualitative or the quantitative, is more useful for the development of this field.

Lipid Biomarkers for a Hypersaline Microbial Mat Community

Jahnke, Linda L.; Embaye, Tsege; Turk, Kendra A.

2003-01-01

The use of lipid biomarkers and their carbon isotopic compositions are valuable tools for establishing links to ancient microbial ecosystems. As witnessed by the stromatolite record, benthic microbial mats grew in shallow water lagoonal environments where microorganisms had virtually no competition apart from the harsh conditions of hypersalinity, desiccation and intense light. Today, the modern counterparts of these microbial ecosystems find appropriate niches in only a few places where extremes eliminate eukaryotic grazers. Answers to many outstanding questions about the evolution of microorganisms and their environments on early Earth are best answered through study of these extant analogs. Lipids associated with various groups of bacteria can be valuable biomarkers for identification of specific groups of microorganisms both in ancient organic-rich sedimentary rocks (geolipids) and contemporary microbial communities (membrane lipids). Use of compound specific isotope analysis adds additional refinement to the identification of biomarker source, so that it is possible to take advantage of the 3C-depletions associated with various functional groups of organisms (i.e. autotrophs, heterotrophs, methanotrophs, methanogens) responsible for the cycling of carbon within a microbial community. Our recent work has focused on a set of hypersaline evaporation ponds at Guerrero Negro, Baja California Sur, Mexico which support the abundant growth of Microcoleus-dominated microbial mats. Specific biomarkers for diatoms, cyanobacteria, archaea, green nonsulfur (GNS), sulfate reducing, and methanotrophic bacteria have been identified. Analyses of the ester-bound fatty acids indicate a highly diverse microbial community, dominated by photosynthetic organisms at the surface.

Full Text Available OBJETIVO: Analizar los factores sociales asociados al estado de salud de hombres mayores de 60 años que viven en contextos de pobreza en áreas rurales de México. MATERIAL Y MÉTODOS: De febrero a octubre de 2002 se llevó a cabo un estudio transversal, descriptivo, con una muestra intencional de 392 adultos mayores residentes de zonas rurales de los estados de Guerrero, Morelos y Jalisco, utilizando un cuestionario especialmente diseñado y piloteado con anterioridad. Las variables de estudio incluyeron características sociodemográficas, bienestar generalizado, problemas de salud, consumo de algunos alimentos y algunos indicadores de salud mental, fuerza personal y apoyo social. Utilizando el paquete estadístico SPSS v. II.I se llevaron a cabo pruebas de Ji cuadrada de Pearson para variables categóricas; para analizar el consumo diferencial de alimentos se hicieron pruebas de ANOVA de una vía. RESULTADOS: Los ancianos de este estudio eran casados o viudos y tenían un promedio de seis hijos. Los ancianos de Morelos informaron haber padecido un mayor número de enfermedades y haber tenido un consumo más alto de bebidas alcohólicas, en comparación con los ancianos de los otros dos estados. De la muestra total, 60% notificaron el uso tanto de remedios caseros como de medicamentos para aliviar sus malestares de salud. Más de la mitad no recibía apoyo familiar adecuado. CONCLUSIONES: Los resultados de este estudio sugieren que el proceso de envejecimiento entre los hombres participantes es percibido como una carga, fundamentalmente debido al contexto de pobreza en que viven. La falta de ingresos suficientes y acceso a servicios de salud a través de planes de pensión y jubilación adecuados para los ancianos que viven en pobreza, es un problema que requiere de atención inmediata.OBJECTIVE: To analyze the social factors associated with the health status of elderly men, 60 years and older, who live in poverty in the rural areas of Mexico

The role of the matrix-edge dynamics of amphibian conservation in tropical montane fragmented landscapes La dinámica del borde-matriz en bosques mesófilos de montaña fragmentados y su papel en la conservación de los anfibios

Full Text Available Edge effects play a key role in forest dynamics in which the context of the anthropogenic matrix has a great influence on fragment connectivity and function. The study of the interaction between edge and matrix effects in nature is essential to understand and promote the colonization of some functional groups in managed ecosystems. We studied the dynamics of 7 species of frogs and salamanders occurring in 8 ecotones of tropical montane cloud forest (TMCF which interact with adjacent managed areas of coffee and corn plantations in Guerrero, southern Mexico. A survey effort of 196 man/hours along 72 transects detected 58 individuals of 7 amphibian species and 12 environmental and structural variables were measured. The diversity and abundance of amphibians in the forest mostly depended on the matrix context adjacent to the forest patches. The forest interior provided higher relative humidity, leaf litter cover, and canopy cover that determined the presence of some amphibian species. The use of shaded coffee plantations was preferred by the amphibians over the corn plots possibly due to the maintenance of native forest arboreal elements, low management rate and less intensity of disturbance in the coffee plantations than in the corn plots. Shaded coffee plantations reduce the edge effects in TMCF, improve the connectivity between TMCF fragments and increase habitat quality for the forest interior amphibian species. Future wildlife management research should take into account edge and matrix effects to understand species dynamics which move along anthropogenic-natural ecotones in managed ecosystems, thus prioritizing sites to buffer edge effects and increase habitat quality in remaining natural ecosystems.El efecto de borde es un evento clave en la dinámica de algunos bosques, la matriz que rodea a los fragmentos de bosque tiene una gran importancia en el funcionamiento y conectividad de estos fragmentos.

Full Text Available Abstract:In the international media, drug-related violence, corruption and militarization have received much attention. While this is understandable in view of the prominence of border area operations of drug cartels, drug trafficking is a pervasive phenomenon in other parts of Mexico as well, not in the least in significant parts of Western Mexico (especially in Guerrero, Colima and Michoacán. The latter state has a long history of drug production and trafficking (poppies and marihuana, and of military campaigns against it, especially in the area known as the 'Tierra Caliente', Michoacán. In recent decades, however, the situation has acquired a new dimension. This paper will examine the socio-economic and political characteristics of the area and analyse the emergence of drug trafficking as part of profound processes of agrarian transformation, especially since the 1980s. What are these transformations and how can the drug economy of the area be understood? In recent years the Tierra Caliente has become the scene of particularly atrocious confrontations between rivalling drug cartels; hence it was also the first target of military intervention after Felipe Calderón assumed power. How is this explained and what are the main consequences for violence, human rights and the drug and peasant economy?Resumen: Historias del narcotráfico en el México rural: Territorios, drogas y cárteles en MichoacánEn los medios masivos internacionales el tema de las drogas y la violencia relacionada con la corrupción y la militarización ha recibido mucha atención.

Induction of Programmed Cell Death by Parvovirus H-1 in U937 Cells: Connection with the Tumor Necrosis Factor Alpha Signalling Pathway

The human promonocytic cell line U937 undergoes apoptosis upon treatment with tumor necrosis factor alpha (TNF-α). This cell line has previously been shown to be very sensitive to the lytic effect of the autonomous parvovirus H-1. Parvovirus infection leads to the activation of the CPP32 ICE-like cysteine protease which cleaves the enzyme poly(ADP-ribose)polymerase and induces morphologic changes that are characteristic of apoptosis in a way that is similar to TNF-α treatment. This effect is also observed when the U937 cells are infected with a recombinant H-1 virus which expresses the nonstructural (NS) proteins but in which the capsid genes are replaced by a reporter gene, indicating that the induction of apoptosis can be assigned to the cytotoxic nonstructural proteins in this cell system. The c-Myc protein, which is overexpressed in U937 cells, is rapidly downregulated during infection, in keeping with a possible role of this product in mediating the apoptotic cell death induced by H-1 virus infection. Interestingly, four clones (designated RU) derived from the U937 cell line and selected for their resistance to H-1 virus (J. A. Lopez-Guerrero et al., Blood 89:1642–1653, 1997) failed to decrease c-Myc expression upon treatment with differentiation agents and also resisted the induction of cell death after TNF-α treatment. Our data suggest that the RU clones have developed defense strategies against apoptosis, either by their failure to downregulate c-Myc and/or by activating antiapoptotic factors. PMID:9765434

Dengue Fever (DF) is a human vector-borne disease and a major public health problem worldwide. In Mexico, DF and Dengue Hemorrhagic Fever (DHF) cases have increased in recent years. The aim of this study was to identify variations in the spatial distribution of DF and DHF cases over time using space-time statistical analysis and geographic information systems. Official data of DF and DHF cases were obtained in 32 states from 1995-2015. Space-time scan statistics were used to determine the space-time clusters of DF and DHF cases nationwide, and a geographic information system was used to display the location of clusters. A total of 885,748 DF cases was registered of which 13.4% (n = 119,174) correspond to DHF in the 32 states from 1995-2015. The most likely cluster of DF (relative risk = 25.5) contained the states of Jalisco, Colima, and Nayarit, on the Pacific coast in 2009, and the most likely cluster of DHF (relative risk = 8.5) was in the states of Chiapas, Tabasco, Campeche, Oaxaca, Veracruz, Quintana Roo, Yucatán, Puebla, Morelos, and Guerrero principally on the Gulf coast over 2006-2015. The geographic distribution of DF and DHF cases has increased in recent years and cases are significantly clustered in two coastal areas (Pacific and Gulf of Mexico). This provides the basis for further investigation of risk factors as well as interventions in specific areas. Copyright © 2018 IMSS. Published by Elsevier Inc. All rights reserved.

Since the discovery of slow slip events, many methods have been successfully applied to model obvious transient events in geodetic time series, such as the widely used network strain filter. Independent seismological observations of tremors or low frequency earthquakes and repeating earthquakes provide evidence of low amplitude slow deformation but do not always coincide with clear occurrences of transient signals in geodetic time series. Here, we aim to extract the signal corresponding to slow slips hidden in the noise of GPS time series, without using information from independent datasets. We first build a library of synthetic slow slip event templates by assembling a source function with Green's functions for a discretized fault. We then correlate the templates with post-processed GPS time series. Once the events have been detected in time, we estimate their duration T and magnitude Mw by modelling a weighted stack of GPS time series. An analysis of synthetic time series shows that this method is able to resolve the correct timing, location, T and Mw of events larger than Mw 6.0 in the context of the Mexico subduction zone. Applied on a real data set of 29 GPS time series in the Guerrero area from 2005 to 2014, this technique allows us to detect 28 transient events from Mw 6.3 to 7.2 with durations that range from 3 to 39 days. These events have a dominant recurrence time of 40 days and are mainly located at the down dip edges of the Mw > 7.5 SSEs.

Full Text Available El destino de Ahl Shaykh Mâ al-cAynîn está conectado a la resistencia contra la colonización europea en el Sahara y Marruecos. La literatura colonial francesa ha concebido la lucha del Sheij como consecuencia de un panislamismo activista. El contexto tribal regional lleva al Sheij a oponerse a la colonización francesa en Mauritania y Marruecos cuestionándose la legitimidad dinástica alawi. El desarrollo de la yihad concluyó con el nombramiento del sultán de Marruecos. Se subraya las contradicciones de un proyecto político basado en el guerrero tlamid del Sheij y las movilizaciones tribales contra el orden colonial. The fate of the Ahl Shaykh Mâ al-cAynîn is connected to the resistance against the European colonization in Sahara and Morocco. The french colonial literature has conceived the Shaykh’s fight as a consequence of an activistic panislamism. As a matter of fact it is located in a tribal regional context leading the Shaykh to be opposed to the French colonization in Mauritania and Morocco and to question finally the calawi dynastic legitimacy. The development of the jihad concluded in the name of the Moroccan Sultan underlines the contradictions of a political project depending on the warrior tlamid of the Shaykh and tribal mobilizations against the colonial order. The check of the jihad reduces the family’s part in the organization of the resistance; after 1920 this part becomes a secondary one.

A positive wave speed anomaly interpreted as the Cocos slab stretches from the uppermost mantle at the Middle America trench in the west, to the lowermost mantle below the Atlantic in the east. The length and continuity of this slab indicates long-lived, uninterrupted eastward subduction of the attached Cocos Plate and its predecessor, the Farallon Plate. The geological record of Mexico contains Triassic to present day evidence of subduction, of which the post-Late Cretaceous phase is of continental margin-style. Interpretations of the pre-Upper Cretaceous subduction-related rock assemblages are under debate, and vary from far-travelled exotic intra-oceanic island arc character to in-situ extended continental margin origin. We present new paleomagnetic data that show that Triassic, Jurassic and Cretaceous subduction-related rocks from the Vizcaíno Peninsula and the Guerrero terrane have a paleolatitudinal plate motion history that is equal to that of the North American continent. This suggests that these rock assemblages were part of the overriding plate and were perhaps only separated from the North American continent by temporal fore- or back-arc spreading. The entire Triassic-present day subduction record, and hence, reconstructed trench location, can therefore be linked to the Cocos slab, which provides control on longitudinal plate motion of North America since the time of Pangea. Compared to the latest state of the art mantle frames, in which longitudes are essentially unconstrained for pre-Cretaceous times, our reconstructed absolute position of North America requires a significant westward longitudinal shift for Mesozoic times.

En la literatura abundan las propuestas de factores de éxito para empresas muy consolidadas, mientras que los negocios de artesanía basan sus expectativas en las preferencias del consumidor, tienen gran variabilidad en su organización, en la formalidad y en la flexibilidad de su estructura, lo que dificulta la utilización de esos factores. Para la obtención de datos se empleó una entrevista estructurada en 337 negocios de artesanía, se realizó en 8 estados de la República Mexicana: Guanajuato, Jalisco, Michoacán, Estado de México, Guerrero, Oaxaca, Puebla y Veracruz. Se utilizó el análisis de regresión lineal múltiple para determinar los factores de éxito. Como resultado se obtuvieron nueve factores de éxito: innovación administrativa, impacto del financiamiento, tecnología de producción, tecnología en administración, capacidad en el manejo del proceso, del empaque, diferenciación e información. Se proponen ecuaciones que pueden ser aplicadas en el manejo del éxito del negocio, para cuando el éxito se mida como satisfacción con el negocio, o por ingresos en ventas, el crecimiento del negocio, o por el tamaño del negocio.

Full Text Available Mycetoma is a chronic granulomatous disease. It is classified into eumycetoma caused by fungi and actinomycetoma due to filamentous actinomycetes. Mycetoma can be found in geographic areas in close proximity to the Tropic of Cancer. Mexico is one of the countries in which this disease is highly endemic. In this retrospective study we report epidemiologic, clinical and microbiologic data of mycetoma observed in the General Hospital of Mexico in a 33 year-period (1980 to 2013. A total of 482 cases were included which were clinical and microbiology confirmed. Four hundred and forty four cases (92.11% were actinomycetomas and 38 cases (7.88% were eumycetomas. Most patients were agricultural workers; there was a male predominance with a sex ratio of 3:1. The mean age was 34.5 years old (most ranged from 21 to 40 years. The main affected localization was lower and upper limbs (70.74% and 14.52% respectively. Most of the patients came from humid tropical areas (Morelos, Guerrero and Hidalgo were the regions commonly reported. The main clinical presentation was as tumor-like soft tissue swelling with draining sinuses (97.1%. Grains were observed in all the cases. The principal causative agents for actinomycetoma were: Nocardia brasiliensis (78.21% and Actinomadura madurae (8.7%; meanwhile, for eumycetomas: Madurella mycetomatis and Scedosporium boydii (synonym: Pseudallescheria boydii were identified. This is a single-center, with long-follow up, cross-sectional study that allows determining the prevalence and characteristics of mycetoma in different regions of Mexico.

[Electoral demography. The demographic dimension of a political process].

Herrero, J M

1991-01-01

A complete and reliable knowledge of the potential voters is indispensable for holding elections in a democratic society. In 1990 a new Federal Code of Electoral Institutions and Procedures (COFIRE) was approved in Mexico. A new list of potential voters was to be created based on the 1990 census and without reference to the old list. The planning and implementation of the 1991 electoral rolls required great efficiency in order to complete the work in time for elections, while assuring its validity and legitimacy through a clear and participatory process in which all political parties played a permanent role. COFIRE designated July 1991 as the date for completion, allowing just 10 months for the entire process from planning to completion. The 1991 work represented a political process as much as a technical challenge. A working group from the political parties provided advice on all aspects of the work, from defining the social communications campaign to cartographic review and organization of field work. Although the list potential voters not intended for demographic purposes, its validity, coverage, and variety of information make it a rich source of sociodemographic information. An estimated 95% of individuals included in the 1990 census were included in the lists of prospective voters. Of these, 39,500,000 citizens, or 86% of the census population, actually registered as of the deadline on May 31. The final coverage by states varied from a low of 79.3% in Guerrero to a high of 91.0% in the Federal District.

The Comprehensive Nuclear Test-Ban-Treaty (CTBT) is a treaty that prohibits all the nuclear explosions by anybody and in any place, either on the terrestrial surface, in the atmosphere, under the sea or underground. From the adoption of this Treaty by the United Nations, Mexico has had interest for its entrance in vigor, as integral part to assure the international peace. For this reason, our country signed the Treaty since it was open in September 24, 1996 and three years later ratified it, due to Mexico is part of the group of necessary countries for their entrance in vigor. During 13 years, the country has been committed and helped to the installation of monitoring stations, actions that allow the strengthening of the International System of Surveillance. The purpose of this work is to divulge the Treaty,its technologies and benefits; and also to diffuse the works realized by Mexico regarding the radionuclides monitoring station and noble gases both certified ones for the CTBT. Besides the radionuclides technology, Mexico has taken charge of the installation and operation of the seismic stations and hydro-acoustics that have been certified too. The radionuclides station Rn-44 located in Guerrero Negro, BCS has two technologies, an automated sampler of suspended particles in air brand Cinderella/ARAME and a noble gases system Sauna used for the particles detection of radioactive material gamma emitting and Xenon radioisotopes product of nuclear assays. Both technologies are transmitting data in real time to the International Center of Data. These technologies are shown in this work. (Author)

Cómo terminar con la pobreza que hace referencia a los motivos que se tienen para que las personas efectúen donaciones y el deber que el ser humano tiene para ayudar a los más necesitados. En este sentido, el presente texto tiene como finalidad, preguntarse acerca del problema bioético que supone el que un sujeto o una institución otorguen algún tipo de donación, bajo el supuesto de ¿cuáles son los motivos éticos que a manera de imperativo categórico subyacen en el donativo? ¿Por qué ante la abismal brecha entre ricos y pobres el donativo se convierte en un paliativo de equidad social? Y ¿cuáles son las desgracias o hechos que obligan a compartir lo poco o mucho que se tiene? Para lograr esto, el texto se dividirá en dos partes, en primer lugar el presentar algunas objeciones que Singer tendría hacia la “Cruzada Nacional contra el Hambre” que se ha impuesto como meta el Gobierno Federal en México en el presente sexenio y, en segundo lugar, lo acontecido hace algunos meses en territorio nacional con la ayuda que miles de personas brindaron a los daminificados por el huracán Ingrid y la tormenta tropical Manuel, en septiembre del 2013, en especial, brindando su solidaridad al pueblo de Guerrero.
