Full textThis PhD Thesis focuses on the reconstruction of past climatic conditions in the Western Mediterranean Basin, and more precisely on the study of the impact of climate variability at orbital and millennial time scales over oceanographic conditions. The work relies on the study of sedimentological proxies like grain-size and elemental geochemical composition of the sediments for unravelling the changes in terrigenous supplies led by oscillations in climate and oceanographic conditions, namely sea level fluctuations and changes in the termohaline circulation of the Western Mediterranean Sea. Sea level changes associated with glacial cycles have been investigated by analysing the oscillations in grain-size and geochemical composition of the sediment records from the progradational Gulf of Lion margin. Eustatic sea level oscillations have determined stacking of regressive progradational units in the upper slope following a 100 kyr cyclicity. Sea level fluctuations have modulated sediment accumulation over this margin, with a succession of periods dominated by high fluvial supplies, and periods characterized by the reactivation of erosive processes in the continental shelf such as Dense Shelf Water Cascading during glacial lowstands and interglacial highstands, respectively. The study of climate variability during Marine Isotope Stage 3, between 65 and 20 ka, characterized by rapid climate fluctuations of millennial time scales, may help us to understand how the climate behaves when undergoing rapid changes and therefore might also further increase our understanding of rapid, anthropogenic climate change. The high-resolution study of grain-size oscillations during Marine Isotopic Stage 3 in the Gulf of Lion margin has shown by the first time the occurrence of millennial scale sea level fluctuations associated with climate variability during the Dansgaard-Oeschger cycles identified in the North Atlantic region. Relative high sea level has been observed to occur during warm interstadials of the Dansgaard-Oeschger cycles. These results point to a rapid response of the ice sheets to climate variability during the last glacial period. However, the precise timing and the amplitude of these millennial-scale sea level rises are still to be determined. The termohaline circulation of the Western Mediterranean Sea has been affected by Dansgaard-Oeschger climate oscillations during Marine Isotopic Stage 3 too, as determined by the study carried out in the IMAGES core MD99-2343 offshore Minorca island. Our results show that during Dansgaard-Oeschger cycles the circulation of deep-water masses in the Western Mediterranean was not synchronized with the Atlantic Meridional Overturning Circulation. This confirms the rapid transmission of climate variability between high and mid-latitudes, likely induced by an atmospheric mechanism similar to the present-day North Atlantic Oscillation. Hydrological oscillations within the basin further modulated the termohaline circulation in the Western Mediterranean Sea. During the Holocene a series of short-lived events of enhanced deep-water circulation have been identified to occur with a cyclicity close to 1000 yr, which have been correlated to relatively cold periods recently recognized from the North Atlantic region and in other regions of the world. These results confirm that rapid reorganizations of the climate system usually ascribed to glacial stages are also a common feature during interglacial periods.

Full text--- The present study determined the concentrations of apolipoprotein-B as an indicator of coronary risk in rural populations of the height of Cerro de Pasco to 4340 msnm and urban populations of the level of the sea of Lima at 25 meters. The quantification of this structural protein of atherogenic lipoproteins, and its concentration, is a reflection of the number of particles present atherogenic. Serum concentrations of apolipoprotein-B (Apo-B) were studied in 51 subjects aged between 22 and 48 years of Cerro de Pasco; and of 48 subjects aged between 23 and 50 years of Lima. Se they were measured by enzymatic Test for Total cholesterol, triglycerides, HDL-cholesterol, LDL cholesterol; and Test Inmunoturbidimétrico to Apo-B. The found values of Apo-B ±DS for the town of Cerro de Pasco was 109. 39±25. 18 mg % and for the population of Lima was 106. 3±33. 12 mg %, which indicates a rise in the levels of this apolipoprotein, which was not expected in this population, and reflecting the change of habits dietary, especially in the intake of carbohydrates and lipids. The correlation between the Apo-B and LDL-cholesterol was 0.9196 for the population of Cerro de Pasco and 0.8932 for the population of Lima, which tells us that both parameters are closely linked in terms of quantity and hence in terms of consequences for the evaluated cardiovascular risk. Key words: Lipoprotein, apolipoprotein-B (Apo-B), coronary risk and atherosclerosis.

Full textIntroduction. Living in high altitudes mandates that villagers adapt biologically and socially to the environment. The objective of this study was to determine the difference in physical performance (PP) in rural populations at sea level and at high altitude. Material and methods. A cross-sectional study was conducted in rural communities in Ancash, Peru, located at 3345 meters above sea level (m.a.s.l.) and also in communities located in coastal areas at 6 m.a.s.l. PP was measured by the Short Physical Performance Battery (SPPB) and other associated factors. Adjusted prevalence ratios (aPR) were calculated. Results. 130 older adults were assessed in the high altitude communities and 129 on the coast. The median age was 71.4 and 55.6% were female. Low physical performance (SPPB ≤ 6) was 10.0% at high altitude and 19.4% on the coast (p <0.05). Factors associated with low physical performance were residing at the coast (aPR: 2.10, 95% CI 1.02 to 4.33), self-reported poor health (aPR: 2.48, 95% CI 1.21 -5.08), hypertension (aPR: 1.73, 95% CI 1.01 to 2.98), and age (aPR: 1.04, 95% CI 1.01 to 1.07), while being a farmer (aPR: 0.49, 95% CI 0.25 to 0.97), and being independent (aPR: 0.37, 95% CI 0,20-, 072) were found to be protective factors. We also found that the inhabitants of the coast have on average a 0.86 point lower total SPPB than the high altitude ones (p = 0.004). Conclusions. There is an association between altitude of residence and PP in older adults. The prevalence of low PP in older adults in rural areas at sea level is twice as high compared to those living in high altitude rural communities.

Full text--- We studied serum levels of relaxin in the 3 th, 4 th and 5 th month of pregnancy, women postpartum and newborns within the first 24 hours both at sea level as high altitude. The study was performed in 24 pregnant women (18 to 32 years) in the third, fourth or fifth month of gestation in (Cerro de Pasco, 4300 m) and 20 pregnant women of the same gestational age at sea level (Lima, 150 m). Also, we studied the serum levels of relaxin in 09 women and 09 newborns within 24 hours postpartum at the high altitude group and 20 women and 20 newborns within 24 hours at sea level. Relaxin was measured by RIA (Radioimmunoassay), using kits Immunodiagnostic Laboratories (Germany) labeled with I-125 and using the gamma scintillation counter computer in lab of the Institute of Clinical Research at the National University of San Marcos. The results indicate no significant difference between the hormone levels of relaxin in the 3 th, 4 th and 5 th month of pregnancy in women at high altitude and sea level, showing a gradual decrease in serum levels of 3 th to 5 th month both at sea level and at altitude. In postpartum women, levels of relaxin in serum were significantly lower in women at high altitude with regard to sea level. The radio mother relaxin / child relaxin is the same at high altitude as the sea level. Keywords: relaxin levels, pregnant women, postpartum, newborn

Full textEl principal procés en l'escenari a llarg termini que pot causar importants canvis en zones costaneres amb poca elevació (per exemple, el Delta de l'Ebre), és l'Elevació del Nivell del Mar. Degut a això, es reproduïxen tres escenaris d'elevació del nivell del mar per a determinar àrees potencialment inundables, tenint en compte el paper de les estructures interiors -com canals, dics i carreteres- en la prevenció d'inundacions.
L'escenari extrem o episòdic, s'associa a processos amb períodes de retorn molt amplis i que no presenten una periodicitat en el temps. En aquest cas, es van identificar les àrees inundables associades a tempestes costaneres amb períodes de retorn de 10, 50, 100 i 500 anys. Per a la determinació d'aquestes àrees, es va identificar la resposta morfodinámica de la costa i la distribució de la inundació a la part posterior de la platja.
Així mateix, es va dur a terme una avaluació dels danys i pèrdues associades a la inundació. Per a això es van emprar els valors dels serveis ecològics de l'ecosistema. I es va implementar un indicador de Vulnerabilitat Costanera a l'Erosió per Tempestes.
Esta tesis propone un marco metodológico para la determinacion de Areas con Riesgo a Inundaciones y la Evaluación de Daños por Tormentas Costeras, en dos escalas de trabajo: una a largo plazo relacionada con la Elevacion Relativa Nivel del Mar y una episódica/extrema relacionada con eventos de tormenta. La incorporación de la respuesta morfodinamica de la costa a eventos de tormenta es una parte fundamental de esta propuesta. Este marco metodológico fue aplicado en el Delta del Ebro.

Así mismo se llevo a cabo una evaluación de los daños y perdidas asociadas a la inundación. Para lo cual se emplearon los valores de los servicios ecológicos del ecosistema. Y se implemento un indicador de Vulnerabilidad Costera a la Erosión por Tormentas.
A methodological framework for Flood Hazard Mapping and Damage Assessment to Coastal Storms was proposed in this thesis in two working scales: A long-term scale related to Relative Sea-Level Rise, and an episodic/extreme scale related to storm events. The incorporation of coastal response to storm events in this framework is a basic part of this proposal. This methodological framework was aplied to the Ebro Delta.
In terms of the long term scale, the Relative Sea Level Rise is the main process that can cause important changes in low-lying coastal areas, such as Ebro Delta. Three possible scenarios of sea level rise were reproduced to determine potentially flood areas considering the paper of the inner structures - like channels, docks and highways - in the floods prevention.
The extreme/episodic scenario is associated to processes that have very large return periods and do not exhibit a periodicity in the time. Flood areas associated to coastal storms with return periods of 10, 50, 100 and 500 years were identified. For this aim, the coastal morphodynamic response and the backbeach flood distribution were studied.
Additionally, an evaluation of the lost and damages associated to flood was carry out. For this study, the values of the ecological services of the ecosystem were used. An indicator of Coastal Vulnerability to the Erosion by Storms was also implement.

El material biológico fueron 50 cuyes. La formación ósea fue inducida mediante osteotomía en el maxilar inferior, asignándose 5 grupos: Grupo Control (10 cuyes), Grupo mar 15 días (grupo expuesto a presión de oxígeno ambiental de 157 mmHg y sacrificado a los 15 días, 10 cuyes), Grupo altura 15 días (grupo expuesto a presión de oxígeno ambiental de 107 mmHg y sacrificado a los 15 días, 10 cuyes), Grupo mar 30 días (grupo expuesto a presión de oxígeno ambiental de 157 mmHg y sacrificado a los 30 días, 10 cuyes), Grupo altura 30 días (grupo expuesto a presión de oxígeno ambiental de 107 mmHg y sacrificado a los 30 días, 10 cuyes). Se realizó un conteo de osteocitos mediante estudio histopatológico. El Grupo mar 15 días presentó menor número de osteocitos por campo comparado con el Grupo altura 15 días (63.180 vs. 80.310, p < 0.05), lo cual fue estadísticamente significativo. A su vez, el Grupo mar 30 días presentó también menor número de osteocitos por campo comparado con el Grupo altura 30 días (160.640 vs. 167.370, p < 0.05), pero dicho resultado no fue estadísticamente significativo. La menor presión de oxígeno ambiental favorece una mayor formación ósea en cuyes nativos del nivel mar.

Full textThis thesis is an empirical research that aims to analyze how children’s citizen participation is promoted in second cycle classrooms of a public preschool in Magdalena del Mar. The relevance of this study lies in the opportunity it brings to understand the perceptions that teachers have about their practice as promoters of citizen participation in their classrooms and in school. Likewise, the strategies that teachers apply to promote citizen participation in their classroom are described. Based on the results obtained, it can be affirmed that the teachers of the second cycle classrooms of the aforementioned preschool promote citizen participation through various actions that take place in a democratic environment: by recognizing children as citizens, by valuing children's citizen participation, by recognizing themselves as citizen educators, by giving children opportunities to express opinions, by listening carefully, by inviting them to make proposals to solve problems in their environment, among others. Teachers' perceptions of their role, as well as the strategies they practice at school, and in their classroom are the cornerstone of today's citizen training

Introducción: El vivir en grandes alturas genera que los pobladores se adapten biológica y socialmente al ambiente. El objetivo fue determinar la diferencia del rendimiento físico (RF) en poblaciones rurales a nivel del mar y a gran altitud. Material y métodos: Estudio transversal en comunidades rurales de Áncash, Perú, ubicadas a 3.345 m s.n.m. y 6 m s.n.m. Se midió RF según el Short Physical Performance Battery (SPPB) y otros factores asociados. Se calculó las razones de prevalencia ajustadas (RPa). Resultados: Se evaluó a 130 adultos mayores en la comunidad de gran altitud y 129 en la costa, la mediana de la edad fue 71,4 y 55,6 % fueron mujeres. El bajo rendimiento físico (SPPB ≤ 6) fue de 10,0 % a gran altitud y 19,4 % en la costa (p < 0,05). Los factores asociados con un bajo rendimiento físico fueron ser de costa (RPa: 2,10; IC 95 %: 1,02-4,33), tener una percepción de mala salud (RPa: 2,48; IC 95 %: 1,21-5,08), tener hipertensión arterial (RPa: 1,73; IC 95 %: 1,01-2,98), tener mayor edad (RPa: 1,04; IC 95 %: 1,01- 1,07), mientras que ser agricultor (RPa: 0,49; IC 95 %: 0,25-0,97), y ser independiente (RPa: 0,37; IC 95 %: 0,20-,072) serían factores protectores. Asimismo, se encontró que los pobladores de la costa tienen 0,86 puntos menos en el SPPB total que los de gran altitud (p = 0,004). Conclusiones: Existe asociación entre residir en altura y RF en adultos mayores. La prevalencia de bajo RF en los adultos mayores de zonas rurales a nivel del mar es dos veces mayor en comparación a los que viven en comunidades rurales de altura.

Full textEl 11 de marzo de 2011 un terremoto de 8,9 grados en la escala de Richter golpeó las costas de Japón. Tras el terremoto, un tsunami azotó las instalaciones de la central nuclear de Fukushima I, las olas del tsunami alcanzaron las casas de bombas de los sistemas de enfriamiento, dejando estas de funcionar, lo que llevo al colapso de los seis reactores, provocando la fusión parcial del núcleo de tres de ellos, emitiendo a la atmosfera partículas radioactivas. Tras esta catástrofe nuclear, las compañías de seguros advirtieron esta falencia en los sistemas de enfriamiento con agua de mar. Chile es un país sísmico, y por ende, también estamos expuestos a la ocurrencia de tsunamis en nuestras costas. Considerando que muchas de las centrales termoeléctricas construidas o actualmente en proyecto en Chile, cuentan con sistemas de enfriamiento con agua de mar, tendrían estos sistemas de enfriamiento riesgos similares de falla a los de la central nuclear de Fukushima I. En el marco de lo anterior, el presente trabajo de título tiene por finalidad proponer una solución anti-tsunami para los sistemas de agua de enfriamiento en centrales termoeléctricas a carbón. La solución propuesta consiste en separar en la casa de bombas, el foso de filtrado del foso de bombas, reubicando el foso de bombas/motores a una cota protegida ante una eventual inundación en caso de tsunami. Para conducir el agua de mar del foso de filtros a la nueva ubicación del foso de bombas, se propone construir un túnel de conducción de agua de mar bajo la cota del nivel mar. El presente estudio analiza la factibilidad técnica y estima los costos de la construcción de este túnel en dos tipos de suelo, el primero de ellos en un limo cementado y el segundo en roca, en ambos casos se considera un túnel de largo 200 metros. En el caso de un suelo del tipo limo cementado, se estudia la metodología constructiva tunnel liner y se concluye que es técnicamente factible utilizar este método y su costo total aproximado es de MMUS$ 11,7. Por otro lado, en el caso de un suelo del tipo roca, se estudia la metodología constructiva de perforación y voladura y se concluye que es técnicamente factible y su costo total aproximado es de MMUS$ 6,6.

Full textDue to the situation originated in 2020, schools change their educational modality to continue their services through technological and digital media. In the face of this new panorama of education, teachers find themselves facing a new challenge: using ICT to generate meaningful learning in children. One of the elements belonging to ICT with greater functionality and access to transmit initial knowledge currently, are digital resources, therefore its mode of application in the level sessions is extremely important and decisive in the development of this modality. Based on this digital education, arises the general objective of analyzing the use that teachers of the initial level give to the resources within the virtual modality of in a private educational institution in the Magdalena del Mar district. The first specific objective is to classify the digital resources used by pre-school teachers in the virtual mode of education and the second, which complements it, seeks to identify the digital skills of pre-school teachers in the use of digital resources. The focus of this research is qualitative at the descriptive level, which uses the interview technique to collect the necessary data from the informants. Data that after contrasting them with theory shows a varied use of digital resources in terms of type and function, however, the basic digital skills that have limitations on different occasions.

Full textThe present study is based on the personal interest of the researcher in knowing the strategies used by early-school teachers to involve parents in the education of their children. Likewise, in the framework of remote education, which is the context of this study, ICTs play a predominant role in the strategies designed by teachers. Therefore, the information obtained from this study is a contribution to the educational community, as it responds to the needs and demands of the current context. Based on this, the main objective that defines this research is "To describe the strategies used by pre school teachers to promote parental involvement in the framework of remote education in a state educational center in the Magdalena del Mar district." For this reason, the thesis has a qualitative methodological approach and is descriptive. Findings show that pre-school teachers use dialogue to involve their parents and bring them closer to school. In addition, it is obtained that the school-parent relationship is not so pervasive in the framework of remote education, thus affecting the involvement of the parent in the activities proposed by the teacher. Even work and family factors are evident that made it difficult for the father to participate in the educational process of his children.

Full textThis essay is an investigation of the functions of the intertextuality in Laura Restrepo’s novel Isle of Passion. The quotations and allusions that refer to Cervantes’ Don Quixote, Defoe’s Robinson Crusoe and the Bible are examined and the context in which these intertextual references appear is taken into account when analyzing the functions they fulfil in the story of the novel. The conclusion reached is that a quotation in the form of an epigraph constitutes the intertextuality between Isle of Passion and Don Quixote and that the intertextual references to Robinson Crusoe and the Bible appear as allusions. Furthermore, the functions of the intertextuality in Isle of Passion are to provide foreshadowing, to create irony and to describe events and characters, sometimes in the shape of similes and metaphors. Finally, the essay states that in the novel the functions of the intertextual references do not vary according to the type of work that the intertextuality refers to, although the biblical allusions tend to be similes.

Full textLastly, the atmospheric surge was estimated from a statistical point of view. The numerical modelling requires a high computational effort, and hence, when the time coverage or the spatial extent under study is large, a different approach should be considered. A multivariate regression model was used to statistically reconstruct the surge levels from the 20th Century Reanalysis. This is done by finding the relationship between the atmospheric fields (mean sea level pressures) and the surge. This statistical simulation allowed us to developed a global atmospheric surge database that covers the period from the end of the XIX century to the present. According to the general objective of this thesis, the study of the atmospheric surge from these different viewpoints, contributed to a better understanding of this sea level component, giving insights of their characteristics at different temporal and spatial scales, and also about the advantages and shortcomings of the different simulation methods.

The rol of NO in the pulmonary arteriolar hypertrophy and right cardiac hypertrophy observed in ascitic syndrome is still unknown. Hence, the aim of this study was to obtain the values of nitrites and nitrates, stable metabolites of NO, and its correlation with the degree of pulmonary arteriole hypertrophy through the muscular wall/arteriolar diameter (CM/DA) ratio, the right ventricular hypertrophy through the right ventricle/total ventricle (RV/TV) ratio and right ventricle/body weight (RV/BW) ratio in chickens rised at environmental hypoxia. A total of 135 male, Cobb vantres chickens and born at sea level were studied; 15 of them were sacrificed at 1 day age and diverse variables were determinate in their samples whose results were used as comparative base line for those of the other animals. The reminder 120 chickens were distributed in the groups: Sea Level (SL) 60 birds and altitude (A) 60 birds. At 10, 20, 30 and 40 days old, 15 chicken were taken randomly to measure body weight (BW), hematocrite (Ht), nitrites and nitrates, MW/AD, RV/VT and RV/BW.

Full textThe subtropical latitudes of South America have been experiencing a major hydroclimatic change since the early 1970’s that has had a major societal impact affecting the local economy of one of the most densely populated regions. This change resulted in an abrupt increase in lake levels including Laguna Mar Chiquita, a lake which now covers 6000 km2, while the sedimentary records over the last millennium show a long drying trend. In order to gain a better understanding of the relation between lake level fluctuations and the climate variability in this region, this work aims to simulate the hydrological behaviour of Laguna Mar Chiquita and the relationship with its catchment. The implementation of the lake water balance indicates that lake fluctuations at the beginning of the 1970’s were in direct response to increased runoff in its northern sub-basin, suggesting a tropical climate influence. The coupling of the lake water balance with a hydrological watershed model has led to simulate lake level variations in relation with the climate of the northern sub-basin, highlighting the minor human impact in the recent hydroclimatic transition. For the first time, an integrated basin-lake model in link to global climate is presented combining the results of hydrological basin-lake modelling with the outputs of the climate LMDZ model through a statistical downscaling approach. This novel approach allows to explore the ability of global climate models to accurately represent the regional climate. In addition, it confirms the tropical influence on forcing of recent hydrological variabilities in this region of South America

Full textWireless mesh networks (WMNs), because of their advantageous characteristics, are considered as an effective solution to support voice services, video and data in next generation networks. The IEEE 802.16-d specified for WMNs, through its mesh mode, two mechanisms of scheduling data transmissions; namely centralized scheduling and distributed scheduling. In this work, we evaluated the support of the quality of service (QoS) of the standard by focusing on distributed scheduling. System problems in the support of voice traffic have been identified. To solve these problems, we proposed a protocol for supporting VoIP, called Assisted VoIP Scheduling Protocol (AVSP), as an extension to the original standard to support high QoS to VoIP. Our preliminary simulation results show that AVSP provides a good improvement to support VoIP.
