description: I året 995 skrev benediktiner-nonnen Roswitha av Gandersheim en pasjonshistorie om martyren Pelagius. En del av handlingen utspiller seg i Cordoba. Selv om hun i sitt liv aldri kunne besøke byen hun skrev om, så var beundringen for Cordoba så stor, at hun valgte hun å beskrive Cordoba med ordene ”Clarum Decus Orbis”, eller ”verdens ornament”. Denne unike rollen hadde kultur og kunst i Andalus fått gjennom sammensmelting av romersk, arabisk og europeisk kulturtradisjon, som befruktet hverandre gjennom flere århundre naboskap av muslimer, jøder og kristne.

I mars 2023 fikk studenter fra kurset ”Bygningshistorie” ved NMBU på Ås anledning til å besøke Cordoba og Granada for å få et inntrykk av denne spennende epoken og la seg inspirere av den multikulturelle kulturen i dette unike europeiske landskapet.

description: In this Letter a topological interpretation for the string thermal vacuum in the Thermo Field Dynamics (TFD) approach is given. As a consequence, the relationship between the Imaginary Time and TFD formalisms is achieved when both are used to study closed strings at finite temperature. The TFD approach starts by duplicating the system's degrees of freedom, defining an auxiliary (tilde) string. In order to lead the system to finite temperature a Bogoliubov transformation is implemented. We show that the effect of this transformation is to glue together the string and the tilde string to obtain a torus. The thermal vacuum appears as the boundary state for this identification. Also, from the thermal state condition, a Kubo-Martin-Schwinger condition for the torus topology is derived.

description: This study identified duty-related stressors and examined the frequency of stressors, prevalence of Posttraumatic stress disorder (PTSD) and PTSD symptoms in male and female members of the Royal Canadian Mounted Police (RCMP). Differences based on years of service, gender, symptoms and prevalence of PTSD as well as coping and social support were explored. The study was conducted via self-administered survey of 92 police officers (73 males and 19 females). Of the 92 participants, 41 (32 males, 9 females) completed all the items of the survey. Results indicated that the male members identified armed violent arrests, serious threats made against themselves/family or friends as the most stressful, while women identified fatal motor vehicle accidents and sudden death as the most stressful events. There was a significant relationship between years of service and frequency of stressors. The prevalence of PTSD in the sample was 4.9%. There were difference in PTSD symptoms met by gender, but no significant differences were found for coping or anxiety.

description: In the recent years India’s agricultural sector has experienced significant changes in institutional and policy interventions and productivity at the national and sub-national levels. But although overall production has increased growth has slowed down, inter-state and intra-state disparities continue to remain very high and even widened in some cases. Using Principal Component Analysis technique and constructing district-wise agricultural development indices, this paper analyses the spatio-temporal variations in agricultural development in Odisha , India for 3 years over the period 2001-02 to 2011-12, identifies the underlying factors, examines inter-relationships and draws policy implications for improving the agricultural situation. Increasing public investment in agricultural infrastructure including irrigation, establishing appropriate farming systems , developing suitable and affordable technology and crop varieties, augmenting credit delivery and designing region and crop-specific plans and strategies are suggested for moderating spatial inequalities and achieving a less unbalanced regional development in agriculture.

description: Despite fluorescent cell-labelling being widely employed in biomedical studies, some of its drawbacks are inevitable, with unsuitable fluorescent probes or probes inducing a functional change being the main limitations. Consequently, the demand for and development of label-free methodologies to classify cells is strong and its impact on precision medicine is relevant. Towards this end, high-throughput techniques for cell mechanical phenotyping have been proposed to get a multidimensional biophysical characterization of single cells. With this motivation, our goal here is to investigate the extent to which an unsupervised machine learning methodology, which is applied exclusively on morpho-rheological markers obtained by real-time deformability and fluorescence cytometry (RT-FDC), can address the difficult task of providing label-free discrimination of reticulocytes from mature red blood cells. We focused on this problem, since the characterization of reticulocytes (their percentage and cellular features) in the blood is vital in multiple human disease conditions, especially bone-marrow disorders such as anemia and leukemia. Our approach reports promising label-free results in the classification of reticulocytes from mature red blood cells, and it represents a step forward in the development of high-throughput morpho-rheological-based methodologies for the computational categorization of single cells. Besides, our methodology can be an alternative but also a complementary method to integrate with existing cell-labelling techniques.

description: El presente trabajo analiza el tipo de getsion del olivar, o su posible reconversion al bosque mediterraneo, que maximiza la provision de bienes y servicios comerciales y no comerciales de este sistema agrario. Metodologicamente se combinan tecnicas de analisis multiveriterio de agregacion de preferencias indiciduales, el metodo analitico jerarquico (AHP), y el analisis territorial mediante los Sistemas de Informacion Geografica (SIG). La informacion primaria procede de una encuesta a la poblacion para determinar sus preferencias sobre las funciones que deberian cumplir este sistema agrario y de varias entrevistas personales a gripos de expertos, uno para cada funcion, para evaluar como cada sistema de gestion contribuye a la consecucion de estas funciones. Ambas fuentes de informacion se integran posteriormente un SIG que georreferemcia el tipo de gestion que maximiza el bienestar de la sociedad. Los resultados sugieren que la funcion mas valorada del olivar de montana es la fijacion de la poblacion rural (un 24 por ciento), seguida por la produccion de aceite de oliva (un 18 por ciento), la prevencion de incendios (un 17 por ciento) y la lucha contra la erosion (un 16 por ciento). El modelo general de optimizacion plantea reconcertir aproximadamente dos tercios del olicar gestionado de forma convencional por otros tipos de gestion (integral o ecologica) o su reconversion al bosque mediterraneo. In this paper alternative management systems of olive plantations and its restoration to Mediterranean forest are analysed in order to optimise the provision of market and public goods of this agricultural system. Methodologically, the Analytic Hierarchy Process, to assess citizens' preferences for the functions that olive plantations (Olea europaea L.) in mountain areas should provide to Society and experts' opinions about the adequacy of each olive production system for the achievement of such functions, is combined with a Geographical Information System (GIS) to determine changes in agricultural land use to optimise social welfare. According to the populations' responses, keeping the rural population in the villages (24%), the production of olive oil (18%), the prevention of wildfires (17%) and the reduction of soil erosion (16%) are the most valued functions. The general GIS model indicates that two thirds of the conventional production systems should shift toward integrated and organic production systems and restoration of the Mediterranean forest to maximize social welfare.

description: Diese Diplomarbeit untersucht den Bayesschen Ansatz zur Portfolioselektion. Wir benutzen ein nicht-hierarchisches und ein hierarchisches multivariat-Gaussches Bayessches Modell mit zwei verschiedenen Prior-Verteilungen. Aufgrund der mathematischen Unlösbarkeit solcher komplizierten Bayesschen Modelle benutzen wir eine probabilistische Programmiersprache namens Stan, welche den numerischen Markov-Chain Monte Carlo (MCMC) Ansatz zur Inferenz dieser Modelle benutzt. Wir betrachten zwei verschiedene Portfoliooptimierungsmethoden: die klassische Mean/Variance Optimierung und einen direkten Erwartungsnutzen-Maximierungsansatz basierend auf der CRRANutzenfunktion. Wir führen eine Backtest-Analyse, basierend auf einem Datensatz der 10 Industriesektoren des S&P 500 zwischen 1989 und 2016, durch. Wir vergleichen dabei die Bayessschen Modelle und Optimierungsmethoden mit dem klassischen Mean/Variance Ansatz mit Maximum-Likelihood-Schätzer. Obwohl die Baysschen Modelle keine besseren Punktvorhersagefähigkeiten besitzen, war der Einsatz dieser fortgeschrittenen Methoden, aufgrund der Nutzengewinne von 1-2% Zusatzrendite des Sicherheitsäquivalents pro Jahr, gerechtfertigt. Alle zusätzlichen Gewinne konnten durch das Fama-French-Carhart Vier-Faktorenmodell erklärt werden.
description: This thesis investigates the Bayesian approach to portfolio selection. We use a nonhierarchical and a hierarchical Multivariate Gaussian Bayesian model with two different prior distributions. Due to the mathematical intractability of such advanced Bayesian models, we use a probabilistic programming language called Stan, which uses the numerical Markov Chain Monte Carlo (MCMC) approach to do inference on these models. We consider two different portfolio optimization methods: The classical Mean/Variance optimization and an direct expected utility maximization approach based on the CRRA utility function. We conduct a historical backtesting analysis based on a dataset consisting of the 10 industry sectors of the S&P 500 index between 1989 and 2016. We compare the Bayesian models and optimization methods to the classical Markovitz Mean/Variance approach with maximum likelihood estimators. Although the Bayesian models do not provide better point prediction forecast ability, the use of these advanced methods was justified, by providing an utility gain which ranges up to 1-2% additional certainty equivalent return per year. All additional returns can be explained by the Fama-French-Carhart four factor model.

description: Mas alla de la produccion de alimentos y materias primas, la agricultura contribuye en muchas zonas rurales a la conservacion de la biodiversidad, del paisaje y del patrimonio cultural, siendo objetivo de creciente atencion por parte de las politicas agricolas y de desarrollo rural de la UE. Asi, el actual Programa de Desarrollo Rural 2007-2013 preve, en su Eje 2 de Mejora del medio ambiente y el entorno rural, la aplicacion de medidas de apoyo al sector mediante ayudas compensatorias a zonas de montana y en despoblamiento, a la forestacion de superficie agricola y a las medidas agroambientales. ENe ste trabajo, con una encuesta realizada a 356 ciudadanos de la Region de Murcia, se valora a traves de los resultados de un Experimento de Eleccion la utilidad que a los ciudadanos les proporcionan las politicas antes mencionadas en la Comarca del Noroeste de esta Comunidad Autonoma, realizando una valoracion monetaria de las mismas en terminos de precios implicitos. La comparacion de los resultados con el presupuesto previsto por las Administraciones Publicas para gasto en este Eje pone de manifiesto tanto su insuficiente financion como una importante divergencia en su reparto por medidas. Beyond food and raw materials production, agricultre contributes to the biodiversity, landscape and cultural heritage conservation, being the focus of considerable attention on the part the common agricultural and rural development policy of the European Union. The Axis 2 about improving the environment and countryside included in the Rural Development Programme 2007-2013 provides measure as compensatory premiums to mountain and depopulation areas, afforestation of agricultural land, and agri-environmental measures. In this work, by means of a survey to 356 inhabitants of the Region of Murcia, the utility of the implementation of the above measures in the Northwest District of the Region is valued by a Choice Experiment. In addition, these measures are estimated in terms of implicit prices. The results are compared with the budget provided by the Public Administration, which highlights its insufficient financing as well as an important divergence as far as its proportional split is concerned.

description: Se analizan por medio de modelos econometricos, empleando datos de encuesta, los factores que explican la contratacion de seguros agrarios por parte de productores ecologicos. Los modelos logit y poisson revelan que aspectos y condicionantes como la percepcion que los agricultores dedicados a la produccion ecologica tienen de cada riesgo, el grado de diversificacion existente en la explotacion o la propia dimension economica de la misma, pueden explicar la utilidad que hoy en dia tiene para dichos productores una herramienta como el seguro agrario, utilizado por un gran numero de ellos con el objetivo de garantizar la proteccion de sus cosechas frente a posibles fenomenos climatologicos adversos. Se demuestra que las variables que condicionan la contratacion de una poliza de seguro agrario difieren mucho entre los cultivos de cereal y fruta ecologica. En el caso de los productores de fruta ecologica, de la variables contempladas en este estudiom son los riesgos de pedrisco y plagas asi como el grado de diversificacion de la propia ecplotacion los que condicionan la decision de contratar. Sin embargo, en el caso de los productores de cerearl ecologico es el tamano economico de la explotacion el que condiciona fundamentalmente la suscripcion de una poliza de seguro. This paper analyzes the main factores that determinate the decision of contracting an agricultural insurance policy by organic farmers using data from a questionnaire and econometric models. Logit and Poisson models reveal the aspects and conditionings of organic farmer's risk perception. The diversification level of their farms and also the economic dimension of their farm can explain how useful the agricultural insurance is nowadays. This tool is used by a great number of farmers in Spain with the aim of protecting their crop against adverse climatic disasters. It is demonstrated in this paper that the variables that determine an agricultural insurance policy subscription is very different between fruit and cereal organic producers. In case of organic fruit producers, hail and plague aversion and diversification level are the variables that determinate the decision of subscribe an agricultural insurance policy. However, for the cereal organic farmers, the variable that fundamentally determine the subscription is the economic size of the main farm

description: We have found that the thin film aluminum structures shaped into a chain of micron sized islands connected by narrow isthmuses, can modify their electrical and structural properties under microwave radiation. As a result, at the temperature of 4.2 K the film structures turn into a kind of lateral periodic structure N-S-N, where N is for normal islands, S is for superconducting isthmuses. Current-voltage characteristics of the samples, as well as changes of these characteristics under low power radiation, have been studied over the temperature range from 1.3 to 10 K. The sensitivity of a structure as a microwave detector runs 10^{5} V/W.

The relation of anxiety to empathy and prosocial behaviour in school-age children
Creators: name: Fessler, Leanne J.
Publisher: name: University of British Columbia
Year: 2010

description: This study examines the relation of anxiety symptoms to empathy-related responses and reports of prosocial behaviour in children. Empathy and prosocial behaviour variables were also considered in order to examine their ability to predict subtypes of trait anxiety. Participants were a community sample of 104 children, ages 9 through 12 years, who completed self-report measures of anxiety, empathy-related responding, and prosocial behaviour. Peers and teachers completed assessments of students’ peer prosocial behaviour. Results indicated that empathic concern, perspective-taking, and personal distress were positively and significantly related to higher rates of self-reported anxiety in children (some variation depending upon the anxiety subtype). Children’s anxiety was generally unrelated to reports of their prosocial behaviour, with the exception of the social phobia subtype. Hierarchical regressions revealed that dimensions of empathy-related responding contributed uniquely to the prediction of all subtypes of children’s anxiety, while prosocial behaviour contributed unique information (beyond that provided by empathy variables) to the prediction of obsessive compulsive and social phobia anxiety subtypes. Implications are discussed considering variable associations, unique characteristics of middle childhood, variations by anxiety subtype, gender differences, construct definition, and measurement issues.

description: The risk or value process of an insurance company, modelled by a Cramer-Lundberg model, is supposed to be controlled by a reinsurance share, that is a part of the risk is undertaken, but also premium has to be divided. The aim is to control this reinsurance level in way, that the discounted value of the risk process maximizes. First, the process is approximated by a diffusion process, then stochastic control theory is used to find an optimal value function and an optimal control. Non-cheap reinsurance and a bankruptcy value are also considered. In the last part of the thesis Monte-Carlo simulation is used to calculate examples and verify the solution.

description: El descenso del sector agrario en Espana puede llegar a ocasionar problemas de indole ambiental, cultural y economico. Las soluciones no deben estar de espaldas a los requerimientos del mercado, por lo que el estudio de las preferencias del consumidor es fundamental. En este trabajo se analiza si la comercializacion en los mercados locales en una alternativa adecuada para los productores agrarios. Para ello, se analiza si la aceptacion del producto local seria buena entre los consumidores locales. El estudio se ha realizado para aceite de oliva virgen extra en la Comunidad Valenciane utilizando la valoracion contingente. Los datos necesarios se han obtenido de una encuesta a 400 consumidores. Los resultados muestran que un porcentaje elevado de poblacion presente una buena respuesta a los productos locales, y ello, pese a que el aceite de oliva virgen extra no es un producto alimentario particularmente ascoiado a esta Comunidad. The decline of the Spanish agricultural sector may cause several environmental, cultural and economic problems. The solutions shouldn't be back to market requirements. So, the study of the consumer preferences is essential. In this paper, the proposed alternative is the production of agricultural products with subsequent commercialization in the local market. The suitability of the alternative is measured by the acceptance of the product n local markets. The research was conducted about extra-virgin olive oil in Valencian Community. The acceptance was determined through contingent valuation. Data source has been a survey of 400 consumers. The results show that a high percentage of population has a good response to local products, despite the fact that olive oil isn't an agricultural product particularly related to the Valencian Community.

description: Las cooperativas de Credito, y mas concretamente las Cajas Rurales, tradicionalmente vinculadas al sector agrario, operan en un entorno fuertemente competitivo, dodnde cada vez estan menos asegurados los <> y la tradicional fidelidad de su clientela. Como cooperativas que son, se espera de ellas el cumplimiento de una serie de objetivos sociales claramente establecidos y definidos, a nivel legislativo y estutario, y socialmente reconocidos. Sin embargo, como entidades financieras, deben operar en un entorno donde es fundamental la busqueda de rentabilidad como via de creacion de valor y servico, sostenida sobre unos adecuados niveles de solvencia. Este trabajo se centrara en analizar, por un lado, la participacion del sector agrario en el modelo de negocio de las cooperativas de credito, comparativamente con la situacion en Bancos y Cajas de Ahorros, y por otro, el peso que las Cooperativas de Credito tienen en la financiacion a los diferentes sectores productivos, y mas concretamente al sector agrario, respecto de las restantes entidades financieras. La situacion actual de crisis ha impulsado el debate interno en el sector de las Cooperativas de Credito, sobre la necesidad de un replanteamiento de su modelo de negocio. Cooperative Banks, and more specifically Rural Banks, traditionally linked to the agrarian sector, operate in a strongly competitive environment, where the <> and the traditional loyalty of its customers are less and less assured. As cooperatives, they are expected to fulfill a series of social aims, clearly established at a legislative and statutory level, socially recognized. Nevertheless, as financial institutions, they must operate in an environment where the search of profitability is mandatory as route of creation of value and service, based on suitable levels of solvency. This will analyze, on the one hand, the participation of the agrarian sector in the business model of Credit Cooperatives, comparatively with the situations in Banks and Savings Banks, and on other one, the weight that the Credit Cooperatives have in the financing to the different productive sectors, and more concretely the agrarian sector, with regard to the remaining financial institutions. The current situation of crisis has driven the internal debate in the sector of the Credit Cooperatives, on the need of a rethinking of his business model.

description: Boxy, peanut- or X-shaped "bulges" are observed in a large fraction of barred galaxies viewed in, or close to, edge-on projection, as well as in the Milky Way. They are the product of dynamical instabilities occurring in stellar bars, which cause the latter to buckle and thicken vertically. Recent studies have found nearby galaxies that harbour two such features arising at different radial scales, in a nested configuration. In this paper we explore the formation of such double peanuts, using a collisionless N-body simulation of a pure disc evolving in isolation within a live dark matter halo, which we analyse in a completely analogous way to observations of real galaxies. In the simulation we find a stable double configuration consisting of two X/peanut structures associated to the same galactic bar - rotating with the same pattern speed - but with different morphology, formation time, and evolution. The inner, conventional peanut-shaped structure forms early via the buckling of the bar, and experiences little evolution once it stabilises. This feature is consistent in terms of size, strength and morphology, with peanut structures observed in nearby galaxies. The outer structure, however, displays a strong X, or "bow-tie", morphology. It forms just after the inner peanut, and gradually extends in time (within 1 to 1.5 Gyr) to almost the end of the bar, a radial scale where ansae occur. We conclude that, although both structures form, and are dynamically coupled to, the same bar, they are supported by inherently different mechanisms.

description: The main sequence of galaxies, a correlation between the star formation rates and stellar masses of galaxies, has been observed out to $z\sim4$. Galaxies within the scatter of the correlation are typically interpreted to be secularly evolving while galaxies with star formation rates elevated above the main sequence are interpreted to be undergoing interactions or to be Toomre-unstable disks with starbursting clumps. In this paper we investigate the recent merger histories of three dusty star forming galaxies, identified by their bright submillimeter emission at $z\sim1.5$. We analyze rest-frame optical and UV imaging, rest-frame optical emission line kinematics using slit spectra obtained with MOSFIRE on Keck I, and calculate Gini and M$_{20}$ statistics for each galaxy and conclude two are merger-driven while the third is an isolated disk galaxy. The disk galaxy lies $\sim$4$\times$ above the main sequence, one merger lies within the scatter of the main sequence, and one merger lies $\sim$4$\times$ below the main sequence. This hints that the location of a galaxy with respect to the main sequence may not be a useful discriminator of the recent star formation history of high-M$_{\star}$ galaxies at $z\sim1$.

description: The principle of common cause is discussed as a possible fundamental principle of physics. Some revisions of Reichenbach's formulation of the principle are given, which lead to a version given by Bell. Various similar forms are compared and some equivalence results proved. The further problems of causality in a quantal system, and indeterministic causal structure, are addressed, with a view to defining a causality principle applicable to quantum gravity.

description: The aim of this article was to evaluate the consumption of milk and milk products by the students of the University of Economics in Wroclaw. The study used a questionnaire which was filled by 130 full-time students aged 20-24.The collected data show that 40% of students consume milk at least once a day, including almost half of men and 38% women. Students were more likely to have used butter than margarine as bread spreads. Students most often choose milk with a fat content up to 2%. Among cheeses most consumed was yellow cheeses and cottage cheese spreads. Most of the students have milk drinks, both natural and fruit flavor in their diet. Students are aware of the importance of milk and dairy products in their diet.

description: Die theoretische Beschreibung von Schwerionenkollisionen stellt ein aktives Forschungsgebiet dar. Experimentell werden Schwerionenkollisionen an Anlagen wie beispielsweise dem LHC am europäischen Kernforschungszentrum CERN und dem RHIC am Brookhaven National Laboratory durchgeführt. Das „Color Glass Condensate“ (deutsch: Farbglas-Kondensat) stellt ein geeignetes Modell dar, um Schwerionen bei hohen Energien zu beschreiben. In diesem Modell erfolgt eine Trennung der Freiheitsgrade nach ihren longitudinalen Impulsen entlang der Bewegungsrichtung des Kerns. Die „harten“ Partonen, welche longitudinale Impulse größer als die der Trennungsskala besitzen, können ausintegriert werden und dann als effektive, klassische Farbladungsdichte aufgefasst werden. Diese wirkt dann als Quellterm für die Dynamik der „weichen“ Freiheitsgrade, welche longitudinale Impulse kleiner als die der Trennungsskala besitzen. In diesem Modell kann der Erwartungswert von Observablen durch die Mittelung über unterschiedliche Ladungskonfigurationen berechnet werden. Die statistische Verteilung der Farbladungsdichten erfolgt über eine Gewichtsfunktion. Bei sehr hohen Energien kann die Gewichtsfunktion durch eine Gauß-Verteilung beschrieben werden, was unter dem Namen McLerran–Venugopalan-Modell bekannt ist. Um Rechnungen bei niedrigeren, experimentell zugänglichen Energien durchzuführen, benötigt man die Gewichtsfunktion für die Energieskala, die von Interesse ist. Wie man durch Integration von weiteren Freiheitsgraden eine Verschiebung der Energieskala, bei der die Trennung in „harte“ und „weiche“ Moden erfolgt, durchführen kann, wird durch die sogenannte JIMWLK-Renomierungsgruppengleichung beschrieben. Diese wurde Ende der 1990er Jahren erstmals formuliert. In dieser Arbeit leiten wir die JIMWLK-Gleichung im Detail her. Des Weiteren führen wir eine Entwicklung der Gleichung für schwache Felder durch und zeigen explizit, dass dies zur BFKL-Gleichung, welche seit den 1970er Jahren bekannt ist, führt.
description: The color glass condensate framework is suitable for describing heavy nuclei at high energies. In this framework there is a cutoff scale separating the degrees of freedom according to their longitudinal momentum along the direction of the propagation of the nucleus. The “hard” partons can be integrated out and they contribute to a classical color charge density distribution which acts as a source term for the dynamics of the “soft” partons. A suitable model to describe the gluon distribution at very large energies is the McLerran–Venugopalan model. Passing from one energy scale to a lower energy scale can be accomplished by the JIMWLK renormalization group equation. We perform a detailed analysis of the JIMWLK equation and its derivation. Furthermore, we perform a weak field expansion of the JIMWLK equation and show that it leads to the BFKL equation explicitly.

description: We explore the possibility that GW190412, a binary black hole merger with a non-equal-mass ratio and significantly spinning primary, was formed through repeated black hole mergers in a dense super star cluster. Using a combination of semi-analytic prescriptions for the remnant spin and recoil kick of black hole mergers, we show that the mass ratio and spin of GW190412 are consistent with a binary black hole whose primary component has undergone two successive mergers from a population of $\sim 10M_{\odot}$ black holes in a high-metallicity environment. We then explore the production of GW190412-like analogs in the CMC Cluster Catalog, a grid of 148 $N$-body star cluster models, as well as a new model, behemoth, with nearly $10^7$ particles and initial conditions taken from a cosmological MHD simulation of galaxy formation. We show that the production of binaries with GW190412-like masses and spins is dominated by massive super star clusters with high metallicities and large central escape speeds. While many are observed in the local universe, our results suggest that a careful treatment of these massive clusters, many of which may have been disrupted before the present day, is necessary to characterize the production of unique gravitational-wave events produced through dynamics.

description: We present a model for describing flexible polyelectrolytes in a good solvent a nd in the presence of monovalent salt . The molecule composed by $N$ monomers is characterized by the end to end distanc e $R_e=b (Z-1)^γ$ and the number of associated counterions $n$. At high tem peratures the polyelectrolyte behaves as a neutral polymer ($γ=0.588$). Dec reasing the temperature, the macromolecule changes from this extended configurat ion($γ=0.588$) to a stretched form ($γ\approx 1$). At even lower temp eratures, above the Manning condensation threshold, the polyelectrolyte collapse s ($γ\approx 0.3$). Our results show good agreement with simulations.

description: Taking the Institute of Soil Science and Plant Cultivation-State Research Institute in Pulawy as an example, it has been demonstrated that agricultural research is focused on increasing the competitiveness of Polish agriculture. Research results have a significant impact on the agricultural sector by implementing environmentally friendly production technologies, management systems and cost optimization. The proper location of agricultural production and the use of biological and technological progress make it possible to improve product quality. It has been stated that to develop Polish agriculture competitiveness, there is a need to stimulate collaboration of different research teams and enhance the effectiveness of research results transfer to agricultural practice via advisory system. Agriculture differentiation between the regions and groups of farms must be taken into consideration.

description: The appearance of colossal magneto resistance (CM) in Tl$_{2}$Mn$_{2}$O$_{7}$ has stimulated many recent studies of the pyrochlore family of compounds A$_{2}$B$_{2}$O$_{7}$. The double exchange (DE) model of Zener does not describe the CM in Tl$_{2}$Mn$_{2}$O$_{7}$, because its metallic conductivity cannot be explained by doping. Here we employ Hubbard operators to reformulate the intermediate valence model used by Ventura and Alascio to describe the electronic structure and transport properties of this compound $(Phys.Rev. B56, 14533 (1997)). Following Foglio and Figueira (Phys.Rev. B62, 7882 (2000)) we use approximate one-electron Green's Functions (GF) to calculate the thermopower and the static and dynamic conductivity of Tl$_{2}$Mn$_{2}$O$_{7}$ for several magnetic fields. A qualitative agreement was obtained with the experimental measurements of those properties. Although the agreement is far from perfect, these quantities are fairly well described by the same set of system parameters.
