Analysis of the influence of excess cement paste content on the compression strength of UHPC
Authors: Maia Alessandra Tourinho , Ferreira Elizamary Otto , Mazer Wellington
Published: October 2023

This research aimed to propose a rational method for dosing ultra-high performance concretes based on the association of three approaches: the definition of the ideal silica content, the use of the minimum paste volume, and the incorporation of fine basalt artificial sand. Through the combination of experimental methods and granular packing models, a robust experimental program consisting of eight steps was developed, aiming to obtain different compositions of ultra-high performance concretes, with self-compacting characteristics and compressive strength greater than 150 MPa at 28 days, after heat water treatment at 90°C. In addition, the influence of silica content, additional paste volume, different types of cure, test ages, and the addition of metallic fibers on the fluidity and strength of the composites were evaluated. Through the proposed method, the average strength of 186 MPa was achieved in the mix containing the minimum volume of paste, 484 kg∕m³ of cement, and 25% silica fume. The results obtained indicate that the proposed method tends to have the best proportion among the component materials, giving rise to traits that fit the international parameters that define the UHPC, but with reduced paste volumes and consumption of binders lower than those identified in the related literature. Through a rational, economic, and sustainable approach, which aims to optimize the use of higher-cost materials and minimize the use of scarce natural resources, the method contributes positively to the technological development of the sector.

Text of abstract in plants, stress caused by water deficiency is a major problem in agriculture. Therefore, it is necessary to seek alternatives that aim to maximize yielding with minimal water use and no economic loss. Thus, the objective of the present study was to assess the physiological quality of corn seeds produced under different conditions as to amount of water in the soil. Five soil moisture points were determined, based on field capacity (100, 85, 70, 55 and 40%), providing controlled water conditions to two corn hybrids (BRS 1040 and DKB 390). The experimental design consisted of randomized blocks in a split-plot arrangement with four repetitions; water replacement was applied to the plots, and the hybrids, to the subplots. After the seeds were harvested, water content, germination and vigor were determined (seedling emergence, first germination count, germination speed index, accelerated aging, and electrical conductivity). Seeds produced by hybrid DKB 390 expressed better physiological potential. Irrigation depths to keep soil moisture between 75.18 and 94.04% of the field capacity favor the physiological quality of the seeds produced.

O ser humano funciona em harmonia com trilhões de bactérias simbióticas chamadas de microbioma humano. Desequilíbrios na composição ou na função do microbioma são chamados de disbiose e estão intimamente ligados ao desenvolvimento de doenças como a obesidade. Verificar a relação da microbiota intestinal e a obesidade. Revisão integrativa da literatura que incluiu artigos científicos publicados nos últimos 10 anos com seres humanos e animais. Realizou-se uma busca em bancos de dados com os descritores relacionados ao objetivo do estudo. Identificou-se 63 artigos na base de dados, desses somente 6 estudos (n=6) foram incluídos para a revisão. Dos artigos selecionado, 5 foram realizados em humanos e 1 em animais. Observou-se nos estudos em humanos, o aumento de Firmicutes em relação aos Bacteroidetes e Bifidobacterium em indivíduos com sobrepeso ou obesidade. No estudo com os animais a mesma relação se manteve, no entanto, em alguns animais houve o aumento de Bacteroidetes. Este estudo mostrou uma relação positiva entre a obesidade e a população bacteriana intestinal devido ao aumento de Firmicutes em relação aos Bacteroidetes, caracterizando uma disbiose intestinal. A disbiose associada a uma dieta rica em gordura resulta na elevação dos níveis de Lipopolissacarídeos (LPS) que gera o aumento da permeabilidade intestinal, levando ao quadro de endotoxemia metabólica, que está intimamente ligado ao estado inflamatório da obesidade.

Published: October 2023

Our accustomed agricultural practices of tilling the soil continuously and excessive fertilizer applications caused not only a decrease in organic carbon content and soil degradation but also disturbed environmental harmony. With this backdrop, current study was carried out during rainy (kharif) seasons of 2018 and 2019 at the research farm of Trihut College of Agriculture, Dholi, Pusa, Bihar to evaluate the effect of different tillage and nutrient management practices on maize (Zea mays L.). The experiment was laid out in split-plot design with tillage as the main plot and nutrient management as the sub-plot. The results showed significantly superior maize grain yield in PB (6.1, 6.2 mg/ ha) and 60% RDN+GSGN (6.0, 5.9 mg/ha) over CT (4.9, 5.0 mg/ha) and RDF (5.1, 5.4 mg/ha) during 2018 and 2019. Similar trend was followed in stover yield, net returns and B:C ratio. Among path analysis, harvest index and no of grains/cob observed largest direct path coefficient of yield attributes to determine the maize grain yield and stover yield respectively. The results suggest that the adoption of conservation tillage and precise nutrient management practices will help in the realization of better yield with maximum profit by way of reducing the input capital apart from improving soil health thereby sustaining natural resources for future generations.

Published: October 2023

The present study was carried out to decipher the variation in plant phytochemicals, and their effect on developmental, reproduction and survival of Lipaphis erysimi (Kalt.) on diverse Brassica juncea cultivars. These studies revealed significant differences in total nymphal, reproductive and developmental periods, fecundity and offspring survival of L. erysimi on the test B. juncea cultivars. Development period was significantly longer on DRMR 150-35, PM 26, RLC 3 and PM 25, while fecundity and survival were lower on PM 27, RLC 3, NRCHB 101, RH 749, Pusa Tarak, RH 0406 and PM 30, except in a few cases. Total proteins, antioxidants, tannins, phenols and FRAP were significantly higher, and sugars lower in DRMR 150-35, RLC 3, PM 26 and NRCHB 101 as compared to other B. juncea cultivars. Total proteins, total tannins and antioxidants exhibited a significant and positive, while total sugars showed negative correlation, and explained 86.1% variability in total developmental period of L. erysimi. Total sugars revealed a significantly positive and FRAP negative correlation, explaining 35.5% variability in fecundity of L. erysimi. Furthermore, total proteins and total antioxidants also showed significant and negative correlation with offspring survival, and total phenols and antioxidants explained 28.9% variability in offspring survival of L. erysimi on the test B. juncea genotypes. Present study suggests that DRMR 150-35, RLC 3, NRCHB 101 and PM 26 have greater amounts of antinutritional plant defense compounds which adversely affect the developmental and reproductive biology of L. erysimi, and thus could be used in Brassica improvement programme for sustainable crop production.

Authors: Kayikcioglu Meral , Alan Bahadir , Yağmur Burcu
Published: October 2023

Objective: This retrospective study, based on real-life data, aimed to evaluate the clinical characteristics and 2-year cardiovascular outcomes in patients presenting with early acute coronary syndrome (ACS) in a tertiary healthcare center. Methods: Information including at least 2-year endpoint data after index ACS event was retrieved from hospital records. Age limit for early ACS was considered <55 years for males and <60 years for females. Results: Of 985 consecutive ACS patients (770 males; age range, 21-93 years) 361 (36.6%) met early ACS  criteria. Frequency familial hypercholesterolemia (FH) was 7.6% and higher in the young-age group (15.5%) than in the old-age group (3%) (p<0.001). During the follow-up (30 monts), the risk predictors for cardiovascular events were the index event being ST-segment elevation myocardial infarction or non-ST-segment elevation myocardial infarction and the presence of hypertension, and the risk predictors for mortality were female sex, older age, in-hospital cardiovascular complications. Conclusion: A very high rate of early ACS (36.6%) was observed in this retrospective ACS cohort of a single center from Turkey. Compared to older patients, young patients were more smoking, more obese, less diabetic, and less hypertensive. High total cholesterol, high triglycerides, low HDL-cholesterol levels, high non-HDL cholesterol, family history of CAD, and FH were also more commonly observed in the young group. High FH prevalence might be a major factor of the high prevalence of premature ACS in this population. Both the in-hospital and 2-year follow-up mortality rates were significantly lower in the old-age group.
Microbial consortia and polyethylene terephthalate degradation
Authors: Guadalupe Navarro Moreno Leticia , Rangel Cordero Andrea , Felipe Collado Luis , Nolasco Hipólito Cirilo
Published: October 2023

The world is currently facing a very serious pollution phenomenon, which is already part of our daily lives. Improperly discarded plastic becomes tons of waste that, when not properly disposed of, generate serious problems worldwide. As an example we can mention the damage to marine species. To reduce plastic pollution, especially that of polyethylene terephthalate (PET) bottles, recycling techniques such as chemical degradation have been established. In an alkaline degraded PET, elaborated in the Biochemistry laboratory of the Universidad del Papaloapan, microbial growth with the appearance of mycelium was observed. The observed conglomerate was allowed to grow and from it some microbial strains were isolated and identified using microbiological and molecular biology methodologies. The results indicated the presence of several types of microorganisms, mostly fungi, which were found to be part of the cluster formed in the alkaline residue. A series of studies have been initiated with these organisms with the objective of learning how they develop the capacity to adapt to the degradation of PET as a sole carbon source. The importance of the isolated microorganisms has opened a wide range of questions related to biochemistry and microbial genetics; evolution and biological phenomena related to environmental contamination.

Authors: Dias Reinaldo
Published: October 2023

The article explores the intricate relationship between top predator tourism, conservation and socio-economic considerations. Starting with the innate fascination that top predators offer, the article delves into their ecological significance and their representation in cultural narratives. Through a dual methodological approach involving systematic review and secondary data analysis, specific case studies from Africa, the United States, Brazil and India were dissected. These detailed analyses identified the nuances of human-animal interactions, security concerns, economic implications and conservation challenges unique to each region. The comparative analysis revealed common patterns of human-animal conflict, tourism's economic contributions and ethical considerations. An emphasis on community engagement, safety protocols, habitat preservation and sustainable tourism practices was evident in the recommendations. The study concludes with a call for a harmonious blend of tourism aspirations and conservation imperatives, especially amid global challenges such as climate change. Top predator tourism, when carried out ethically and sustainably, presents an invaluable opportunity for both ecological preservation and economic growth.
Criticism of legal positivism through Judge Angelo in the Shakespearean play "Measure for Measure"
Authors: Milhomem Vasconcelos Anderson , De Maria Inácio Parente Aguiar Stefanny
Published: October 2023

This work seeks, through the use of the tool of Law and Literature, to explain the criticism of several theorists of legal positivism, in particular, the studies of Ronald Dworkin. For this, the work elaborated by Shakespeare “Measure for Measure” will be analyzed, which demonstrates in a very clear way all the critical notes in which legal positivism is involved. Through its main character, Judge Ângelo, it will be demonstrated when a judge acts in an exegetical way, that is, he mechanically fulfills the sayings of the laws, and when they start to decide in a way endowed with greater discretion, in which many Sometimes they act in this way to meet desires and understandings that they see as merely personal. Still, the present study seeks to understand the positivist approach to decision making, so that the criticisms that both Dworkin, Hart and Kelsen make to the subject are demonstrated. The present study took place through a qualitative and descriptive approach, with bibliographic research in legal journals, articles and books.

Authors: Machado Militza , Franco Camila
Published: October 2023

Introdução: A relação médico-paciente tem sido muito estudada ao longo dos anos e sua importância na prática médica é um consenso. No final do ano de 2019 o mundo começou a luta contra a pandemia causada pelo novo coronavírus. Os médicos de família e comunidade atuaram na linha de frente da pandemia. Objetivo: Este estudo teve como objetivo analisar as percepções dos médicos de família e comunidade na relação médico-paciente durante a pandemia da COVID-19. Métodos: Trata-se de um estudo qualitativo de análise do conteúdo das narrativas médicas, publicadas no blog "Causos Clínicos". O corpus de análise seguiu a metodologia proposta por Bardin. Resultados: Foram identificadas 42 narrativas com a temática de COVID-19 e relação médico-paciente. Após a análise de conteúdo, foram identificadas três categorias: emoções, contato físico e mudanças no sistema de saúde. Cada uma delas teve subcategorias específicas de acordo com as características das narrativas, podendo estar relacionada com “fortalezas e enfrentamentos”: emoções conflituosas de saúde mental pessoais e também relacionadas ao papel social do médico; a necessidade do distanciamento social, reduzindo o contato físico; mudanças no sistema de saúde próprias desse período, como persistência de demandas clínicas e sociais, redução da disponibilidade de consultas presenciais e falta de insumos básicos de proteção; ou “barreiras e dificuldades”: exercício da empatia; prática da escuta qualificada, do olhar atento e de habilidades de comunicação, além do uso da telemedicina. As informações obtidas na literatura corroboram os resultados encontrados nesta pesquisa. Quanto às limitações, este estudo contemplou apenas o olhar do médico e reuniu outras informações relevantes sobre a temática que não puderam ser incluídas nos resultados. Conclusões: De posse das informações obtidas neste trabalho foi possível concluir que de fato a relação médico-paciente sofreu alterações diante das variáveis identificadas, porém as narrativas revelam que mesmo em tempos de crise é possível estabelecer ligações significativas entre o médico e o paciente.

Zwischen Wahlkreisreduzierung und Bürgernähe: Zur aktuellen Reformdiskussion des Wahlrechts in Baden-Württemberg
Authors: Gschwend Thomas , Rittmann Oliver , Werner Lisa-Marie
Published: October 2023

Discussions on the reform of the electoral law have so far mostly been conducted without the perspective of the sovereign . Therefore, given the current reform discussion and the change of the electoral law in Baden-Württemberg, we examine whether reducing the number of electoral districts leads citizens to perceive the relationship between citizens and representatives as less close . This concern is often cited as an argument against increasing the size of electoral districts . Already now, the electoral districts of the Landtag Baden-Württemberg vary in size . This allows us to analyze whether citizens perceive the relationship between representatives and themselves to be closer in smaller districts . We analyze this question based on the data of the “Demokratie-Monitoring Baden-Württemberg 2016/2017” . 2 .501 respondents from all electoral districts answered questions on their perceived political responsiveness and satisfaction with democracy, which allows us to measure the closeness of the relationship between representatives and citizens, at least indirectly . Our results and model calculations show that respondents in larger districts do not feel more distant to their representatives than respondents in smaller districts . Our results are consistent with similar studies at the federal level . Thus, we conclude that reducing the number of electoral districts can be a sensible remedy against an undesirably large parliament .
Frankreichs Parteiensystem im Umbruch
Authors: Kempf Udo
Published: October 2023

Until 2017 “two blocks” dominated the French political party system . Alternative governments of the left and of the bourgeois-conservative camp have alternated since the 1960s . Due to the drastic losses of the traditional parties as Les Républicains as well as the Socialists and the electoral successes of the liberal-conservative Macron supporters, the supporters of the radical right-wing Le Pen’s movement and the left-wing socialist party under Jean-Luc Mélenchon there has been a new development towards an asymmetry . Since the most recent parliamentary elections in 2022, one can speak of a tripolar system: Alongside Macrons La République en Marche (now Renaissance), the right-wing Rassemblement National under Marine Le Pen and the left-wing group La France Insoumise under Jean Luc Mélenchon . The once dominant parties of the Fifth Republic still exist, but are only a shadow of themselves .
Risk Factors Affecting Public Infrastructure Projects
Authors: Sikhupelo Christopher , Amoah Christopher
Published: October 2023

The delivery of public infrastructure projects in South Africa is bedevilled with many challenges leading to project delays and loss of needed public resources. This study, therefore, sought to identify the risk factors affecting project delivery and the sources of these risk factors. This study employs a qualitative research methodology. To gather the required data, open-ended interview questions were administered to the participants from the various provincial departments in the Northern Cape responsible for delivering public infrastructure construction projects. A purposive sampling technique was used to select the relevant participants to form part of the study. The data collected were analysed using qualitative content analysis. The underpinning factors for these risks affecting project execution are classified as internally and externally generated. The identified risk factors pose a significant threat to project delivery leading to delay and loss of public funds and adequate service delivery to the public. This study helps us understand the risk factors and their source for public infrastructure construction projects. The government and departments in the Northern Cape and other provinces can take measures to tackle these risk factors and alleviate their negative impact on project delivery.
Perspective Chapter: Energy Poverty in Rural Areas – A Contribution to the Development Strategies Debate
Authors: Bermann Celio
Published: October 2023

This chapter discusses the concept of energy poverty and its forms present in rural areas in order to contribute to the debate about the strategies to be considered for achieving the goals established for sustainable development by the 2030 Agenda. The multidimensional nature of energy poverty and its different approaches are highlighted. The characterization of energy poverty in the international rural setting is carried out based on the literature review on the subject, where various aspects are analyzed, such as public policies for rural electrification, and programs to use available energy sources in remote regions to meet the cooking and heating needs of households efficiently. The technological obstacles and financial barriers to be overcome and the solutions’ scope are also discussed. Furthermore, energy poverty in rural areas is addressed from the notion of energy justice in its various dimensions and its relations with environmental justice. The chapter concludes with the indication that energy poverty is related to other socio-economic vulnerabilities and should be included in sustainable development agendas in order to reduce socio-economic inequalities in rural areas.
The Thalassemia Syndromes: New Insights
Authors: Singh Saksham , Kiran Sri Chittala , Bakane Atish
Published: October 2023

Thalassemia is characterized by impaired synthesis of globin chains in hemoglobin. Supportive care for this condition includes regular transfusions and adequate iron chelation. Hemopoietic stem cell transplant (HSCT) is the only curative option available at present to most of the patients. The currently accepted indication for allogenic HSCT is transfusion dependency. For patients with available HLA-matched siblings or related or unrelated donors, a transplant should be offered as soon as possible to avoid transfusion-associated complications. The three risk factors are the presence of hepatomegaly >2 cm, the presence of liver/portal fibrosis and a history of inadequate chelation. Stem cells for HSCT can be obtained from bone marrow, peripheral blood and cord blood. In the majority, all the transplant centres across the world use bone marrow as a stem cell source as it is associated with a lesser incidence of GVHD (especially chronic) as compared to peripheral blood because of the high concentration of T lymphocytes in the latter. Conditioning regimen is being evolved from myeloablative to reduced intensity conditioning to reduced toxicity myeloablative conditioning regimens. Post-transplant management includes monitoring of engraftment and chimerism. It also aims at infection prophylaxis, prevention of GVHD, hematopoietic support and management of iron overload post-transplant.
Perspective Chapter: Building Damage Estimation and Renovation Proposal System Using Constant Microtremor Measurement for Construction Risk Management
Authors: Yoshizawa Itsuro , Takahashi Osamu
Published: October 2023

In this chapter, the authors propose a system that measures microtremors of the ground and buildings and instantaneously calculates building damage estimation and emergency risk assessment. In the conventional damage estimation and emergency risk assessment due to microtremors, resonance judgments are mainly based on the initial state due to microtremors of the ground, and buildings are often seen. However, there is a possibility that the ground and the building will resonate continuously as the ground and the building are cracked and damaged by disturbances such as earthquakes and winds. In addition, the resonance causes great damage to the building. In the system proposed this time, damage estimation and emergency risk assessment are performed not only in the initial state but also during the duration. In addition, as a renovation proposal, a system is proposed that predicts the damage and emergency risk of the building during renovation with earthquake resistance, seismic isolation, and damping. In this system, the building hazard levels are classified into four categories based on two methods: one method involves calculating the response spectrum and transfer function of the building and ground using continuous microtremor measurements to determine the resonance performance, and the other method utilizes the PML (Probable Maximum Loss) values.

Published: October 2023

TIMS (Training in Innovation Management System for Sustainable SMEs) is an EU Erasmus+ project which analyzed the ISO (International Standardisation Organisation) 56000 innovation management system norm parts and configured in 2022 an ISO 56000-based innovation assessment portal. This system allows self-assessment, independent expert assessment, and benchmarking for innovation management. In 2023, a competence matrix and related training materials to support the implementation of ISO 56000 is developed. The ISO 56000-based assessment tool applied ISO 33020 for process capability assessment for ISO 56000 and this allows us to determine the capability of ISO 56000 processes. This paper gives an overview of which processes have been derived from ISO 56000 and how the PAM (Innovation Process Assessment Model) is structured. Since ISO 33020 provides a standard method to determine process attributes and capability level profiles of innovation management system processes, the method also allows a Europe (and worldwide) benchmarking of the capability of innovation management systems. The objective of TIMS is to establish an assessment system and training to roll out ISO 56000 to the European industry. The tools and training materials will be used by universities in lecturing programs and by innovation agents in the industry.
A Methodology to Analyze Soil Moisture Characteristics Using GIS and Modeling Approach for Sustainable Crop Production
Authors: Sharma Upma , Kothari Mahesh
Published: October 2023

This chapter introduces the importance of soil moisture to attain optimum crop production. Various soil properties that play crucial role in managing irrigation system have been discussed. In addition, the lesson presents a detailed description of the in situ techniques for measuring the moisture content of different soils. In areas where field measurement of soil moisture is a cumbersome practice, remote sensing, GIS, and modeling have been emerged as a boon. The role of all three approaches has been studied to analyze the soil moisture characteristics of particular area to select suitable crop and cropping pattern. Salinity and waterlogging are two major problems caused due to improper and unbalanced transport of water and solutes in the soil. A complete methodology has been proposed which includes data collection and measurement of various soil parameters, estimating and simulating future salinity and waterlogging conditions based on current water management practices, quantifying severity levels of saline and water-logged areas and their effect on crop production and optimum policies for managing salinity and waterlogging for better crop productivity. The proposal is an integrated approach comprises of field as well as laboratory measurements, with efficient use of GIS, simulation, and optimization techniques.

Laparoscopic Bikini Line Cholecystectomy
Authors: Gulaydin Nihat , Ozkan Atakan
Published: October 2023

Laparoscopic cholecystectomy (LC) approach is accepted as the gold standard in gallbladder surgeries in the world. However, today, cosmetic expectations of patients have led surgeons to define new surgical techniques that do not create visible scar on the abdominal wall. Two common and well-known techniques for this purpose are natural orifice transluminal endoscopic surgery (NOTES) and single-incision laparoscopic surgery (SİLS). These techniques have long-learning curve and difficulty of implementation, so that have not become widespread. Alternatively, the placement of laparoscopic ports in less visible areas of the body such as the bikini line, termed alternative port site selection (APSS), may result in further improved cosmesis. Laparoscopic Bikini Line Cholecystectomy (LBLC) can be classified into two main groups as Full Bikini Line Cholecystectomy (FBLC) and Modified Bikini Line Cholecystectomy (MBLC), depending on inputs of the ports.
Álvaro Siza : lugar y crisis
Authors:   , Illescas Marín Ángel
Published: October 2023

The initial interpretations of Álvaro Siza’s work outside Portugal put the notion of place at the core of his architecture, in line with certain critical positions that appeared in Europe after the Second World War. From different perspectives towards the idea of place, critics have remained true to the vernacular traditions, the revelation of pre-existing regulating lines and the architectural promenade when interpreting Álvaro Siza’s architecture.
However, from the early nineties, these terms were no longer sufficient to understand the last stage of his career. Critical regionalism is completely depleted by the global nature of his work in South Korea or China. In Europe too, Álvaro Siza’s current architecture is frequently located in the anonymous suburbs, sparse landscapes and banal spaces that have proliferated in the generic contemporary city. His projects over the last 25 years have rarely revealed the genius loci through the use of the vernacular, nor historical continuity and forms from the immediate environment. Recognizing the multi-faceted crisis of the place, this thesis explores new meanings of ‘local’ in Álvaro Siza’s contemporary work.

Las primeras interpretaciones que recibieron las obras de Álvaro Siza fuera de Portugal situaron la noción de lugar en el centro de su arquitectura, alineadas con ciertas posiciones críticas que nacieron en Europa tras la Segunda Guerra Mundial. Desde diferentes sensibilidades hacia la idea de lugar, la crítica se ha mantenido fiel desde entonces a la tradición vernácula, al desvelamiento de trazados preexistentes y a la experiencia del recorrido en la interpretación de la arquitectura de Álvaro Siza. Sin embargo, desde principios de los años noventa, estos términos ya no son suficientes para comprender la última etapa de su trayectoria. El regionalismo crítico se encuentra definitivamente agotado ante la dimensión global que ha alcanzado su obra en Corea del Sur o China. Pero también en Europa, la arquitectura reciente de Álvaro Siza se inscribe con frecuencia en las periferias anónimas, el paisaje disperso y los espacios banales que han proliferado en la ciudad genérica contemporánea. Sus proyectos de los últimos veinticinco años en raras ocasiones revelan el genius loci a través de lo vernáculo, las permanencias históricas o las formas del entorno inmediato. Reconociendo pues, la crisis poliédrica del lugar, este trabajo explora nuevos significados de lo local en la obra contemporánea de Álvaro Siza.
Sobre la termoelasticidad de materiales simples
Authors:   , Martínez Saez Fernando
Published: October 2023

En esta memoria se estudian diferentes problemas dinámicos relacionados con la termomecánica racional. En el primer capitulo se hace un breve repaso a los distintos tipos de problemas a estudiar y de las herramientas a utilizar, que son básicamente la teoría de semigrupos de operadores lineales.

En el segundo capítulo se estudian las ecuaciones para el problema incremental para la termoelasticidad de materials que ocupan una región no acotada del espacio.

Las teorías incrementales son linealizaciones de las ecuaciones de evolución en el caso en que el estado primario esta pretensionado. Para este problema se obtienen resultados de existencia, unicidad y dependencia continua respecto de parámetros iniciales. Estos resultados son validos bajo la hipótesis de que el tensor de elasticidades es fuertemente elíptico que es más débil que la usual de asumir que dicho tensor RD definido positivo. En el apéndice a este capitulo se analizan algunos ejemplos donde la hipótesis de elipticidad se satisface pero la de positividad No.

En el siguiente capitulo se analiza el problema incremental para materiales porosos. Los materiales porosos están compuestos por un esqueleto elástico y por intersticios vacíos. Para este tipo de sólidos la densidad se puede descomponer como producto de dos campos escalares: y, que depende únicamente de la naturaleza del material, y la fracción volumica, v, que depende de la geometría de los poros. Los resultados obtenidos son de unicidad de soluciones para condiciones de frontera generales y de existencia para condiciones de frontera homogéneas.

En los dos últimos capítulos se consideran teorías viscoelasticas que estudian el problema en que el material presenta mecanismos de disipación debidos a sus estados pasados. Esta dependencia en los estados pasados se refleja matemáticamente en las ecuaciones constitutivas del material que pasan a ser funcionales de la historia de las variables independientes
Contribución al problema de interpolación de Birkhoff
Authors:   , Palacios Quiñonero Francisco
Published: October 2023

El objetivo de esta tesis es desarrollar la interpolación de Birkhoff mediante polinomios lacunarios.

En la interpolación algebraica de Birkhoff se determina un polinomio de grado menor que n, para ello se emplean n condiciones que fijan el valor del polinomio o sus derivadas. Los problemas clásicos de interpolación de Lagrange, Taylor, Hermite, Hermite-Sylvester y Abel-Gontcharov son casos particulares de interpolación algebraica de Birkhoff.

Un espacio de polinomios lacunarios de dimensión n es el conjunto de los polinomios que pueden generarse por combinación lineal de n potencias distintas de grados, en general, no consecutivos. En particular, cuando tomamos potencias de grados 0,1,.,n-1, se obtiene el espacio de polinomios de grado menor que n, empleado en la interpolación algebraica clásica.

En la interpolación algebraica clásica, el número de condiciones determina el espacio de interpolación. En contraste, en la interpolación mediante polinomios lacunarios las condiciones de interpolación determinan únicamente la dimensión del espacio de interpolación y pueden existir una infinidad de espacios sobre los que realizar la interpolación. Esto nos permite construir mejores estrategias de interpolación en ciertos casos, como la interpolación de funciones de gran crecimiento (interpolación de exponenciales y de ramas asintóticas).

La aportación de la tesis consiste en la definición de un marco teórico adecuado para la interpolación de Birkhoff mediante polinomios lacunarios y en la extensión al nuevo marco de los principales elementos de la interpolación algebraica de Birkhoff. En concreto, se generaliza la condición de Pólya, se caracteriza la regularidad condicionada, se establecen condiciones suficientes de regularidad ordenada que extienden el teorema de Atkhison-Sharma, se extiende la descomposición normal y se establecen condiciones suficientes de singularidad en los casos indescomponibles.

Analysis of fractional step, finite element methods for the incompressible Navier-Stokes equations
Authors:   , Blasco Lorente Jorge
Published: October 2023

En la presente tesis se han estudiado métodos de paso fraccionado para la resolución numérica de la ecuación de Navier-Stokes incompresible mediante el método de los elementos finitos; dicha ecuación rige el movimiento de un fluido incompresible viscoso. Partiendo del análisis del método de proyección clásico, se desarrolla un método para el problema de Stokes (lineal y estacionario) con iguales propiedades en cuanto a discretizacion espacial que aquel, explicando así sus propiedades de estabilización de la presión. Se da también una extensión del nuevo método a la ecuación de Navier-Stokes incompresible estacionaria (no lineal).

En la segunda parte de la tesis, se desarrolla un método de paso fraccionado para el problema de evolución que supera un inconveniente del método de proyección relativo a la imposición de las condiciones de contorno.

Para todos los métodos desarrollados, se demuestran teoremas de convergencia y estimaciones de error, se proponen implementaciones eficientes y se proporcionan numerosos resultados numéricos.
