The myth of minority : cultural change in Valencia in the thirteenth century at the time of the conquests of James I of Aragon
No full textThe history of the Iberian Peninsula is intricate and complex. Like most regions of
Western Europe in the Middle Ages, it suffered invasion, occupation, political change and an almost constant re–alignment of social alliances. Yet the thirteenth century saw one of the most massive shifts in the balance of power recorded in western history. In the space of fifty years, Islamic rule within the peninsula was ended for good, with the last vestiges of Muslim territory erased from the southern peninsula by the fifteenth century. Christian ascendancy heralded the arrival of a mixed policy of tolerance, as questions began to be asked about the nature of living together with other cultures and religions and whether this new rule – this new Christian rule – needed to tolerate the existence of others in its midst.
The most dramatic shift in policy occurred in the middle of the thirteenth century, as the campaigns of the two great northern kingdoms of Leon–Castile and Aragon–Catalonia moved southwards. The most dramatic outcome – due to the size of the Muslim population – was the relatively swift conquest of, in the case of Ferdinand III, the main towns of Andalucia and, in the case of James I, king of Aragon, the region of Valencia by 1245. Yet it is important when examining the campaigns of these great warrior kings not
to be overwhelmed by the idea of the religious ethos for the conquest. Some historians have chosen to interpret the thirteenth–century conquests as the Christian reaction for the centuries of subjugation under Muslim rule. The reasoning behind the conquests was far more complex than that of a mere idealistic crusade. In the case of thirteenth–century Christian expansion, desire for territory, sovereignty, inheritance, taxation and inter-territorial rivalry had just as much of a part to play as a desire to overcome the Muslim ‘infidel.’ It is the conquest of Valencia which will form the major focal point of this paper, examining the historical precedent for conquest, the nature of Muslim rule, the ulterior motives of the Christians, the
position of Muslims and Jews in existing Christian society (as well as under the
conquerors) and the role of James I in both consolidating and changing that culture.
The programme of this thesis is divided into two main parts. In the first part, the paper will explore the impact of historical events up to the birth of James; how these events both shaped him as a king and as a warrior; and how domestic concerns may have provided a greater incentive than religious missionaries spreading Crusading fever amongst Western kingdoms. It will review the impact of those close to the king; on the nature of his conquest; on his ideology; and how his attitude towards his conquered subjects was shaped. External political and geographical pressures impacted both upon the king’s campaigning and, ultimately, how complete the conquest was.
In the second part, the thesis will focus on the communities themselves and the changes that occurred as the conquests progressed further and further southwards. It will
contrast the circumstances and fortunes of those conquered with the lives of minority
cultures who were already subjects in the Christian realms. It will examine the idea of
hierarchy within minority culture and the social mores that had an even more direct
impact upon community life than the military campaigning. Most important of all, it will
question the idea of convivencia and the concept of tolerance and ‘living together.
Did the Cooperative Start Life as a Joint-Stock Company? Business Law and Cooperatives in Spain, 1869-1931
No full textStudies of Spanish cooperatives date their spread from the Law on Agrarian Syndicates of 1906. But the first legislative appearance of cooperatives is an 1869 measure that permitted general incorporation for lending companies. The 1931 general law on cooperatives, which was the first act permitting the formation of cooperatives in any activity, reflects the gradual disappearance of the cooperative’s “business” characteristics. In this paper we trace the Spanish cooperative’s legal roots in business law and its connections to broader questions of the freedom of association, the formation of joint-stock enterprises, and the liability of investors in business and cooperative entities. Our account underscores the similarities of the organizational problems approach by cooperatives and business firms, while at the same time respecting the distinctive purposes cooperatives served.cooperative, general incorporation, business enterprise, freedom of association, freedom of contract

el Sanatorio de Agua de DiosEl SANATORIO DE AGUA DE DIOS E.S.E., (Empresa Social del Estado). Se encuentra ubicado en el Municipio de Agua de Dios Departamento de Cundinamarca, tiene por objeto la prestación con el carácter público los servicios de salud para todos los enfermos de Hansen en atención médica, asistencial social, rehabilitación física, a su vez desarrolla programas de promoción y prevención en salud. Casa Médica es un área que presta un servicio adicional de hospedaje-alimentación a los funcionarios del Ministerio de Protección Social, Direcciones Seccionales y de Instituciones prestadoras del Servicio de Salud Pública y Privadas.
Los ingresos del Sanatorio son adquiridos principalmente por el Ministerio de Hacienda Nacional, adicionalmente recibe ingresos por parte de los diferentes contratos que tiene suscritos con las Entidades Prestadoras de Servicios de Salud (EPS).
Las organizaciones han venido desarrollando sistemas de evaluación de desempeño a las áreas operativas con el fin de medir el aporte de cada una dentro del proceso productivo. Por ello el Sanatorio de Agua de Dios ha incorporado a sus sistemas de calidad el sistema de costo ABC (Activity Based Costing) o costeo por actividades, a pesar de que sus procesos se enmarcan por este sistema, el área de Alimentación Casa Médica no cuenta con esta metodología. El actual sistema de costos que trabaja Casa Médica es tradicional, el cual no permite la identificación real de la materia prima (insumos directos e indirectos),
La situación actual del sistema de costos de Alimentación Casa Médica se conoció a través de una serie de entrevistas realizadas a los funcionarios de esta área, entre ellas el departamento financiero y economato. Revisión a los despachos Casa Médica en los meses de Enero, Febrero y Marzo suministrados por la entidad.
Así entonces el proyecto implementa herramientas de análisis organizacional que permite identificar la situación financiera de Casa Médica, estas no brindaran las pautas para determinar los gastos generales, directos e indirectos que se incurren para la elaboración de los productos. A través de entrevistas con los líderes de área y análisis sectorial de los costos, podemos calcular el costo de venta real, y de esta manera poder recomendar una metodología de costeo eficiente que aporte a la auto-sostenibilidad de Casa Médica.The SANATORIO DE AGUA DE DIOS E.S.E., (Social Enterprise of the State). It
is located in the Municipality of Agua de Dios Department of Cundinamarca; its purpose
is to provide public health services for all Hansen patients in medical care, social
assistance, physical rehabilitation, in turn develops promotion programs and prevention in
health. Medical house is an area that provides an additional service of lodging-feeding to
the officials of the Ministry of Social Protection, Sectional Directorates and Institutions
that provide the Public and Private Health Service.
The income of the Sanatorium is acquired mainly by the Ministry of National
Finance, additionally receives income from the different contracts that it has signed with
the different Health Services Providers (EPS).
The organizations have been developing performance evaluation systems for the
different operational areas in order to measure the contribution of each one within the
production process. For this reason the Agua de Dios Sanitarium has incorporated into its
quality systems the cost system ABC (Activity Based Costing) or costing by activities,
although its processes are framed by this system, the Casa Médica Food area does not
have this methodology. The current system of costs that Casa Médica works is traditional,
which does not allow the real identification of the raw material (direct and indirect
inputs),
The current situation of the Casa Médica Health Fees system was known through a
series of interviews with officials in this area, including the financial department and the
commissary. Review of Medical Home offices in the months of January, February and
March provided by the entity.
According to the shortcomings found, the implementation of the cost-per-activities
system for the restaurant services of Casa Médica is designed as a tool for the optimal
development of the activities carried out there, in this way to mark an advantage that lasts
in the time and that allows the decision making. Since it was identified that there are
many losses of raw material in the preparation of food and it is important to improve the
allocation of costs
Design and Implementation of a Low-Cost Air Quality Network for the Aburra Valley Surrounding Mountains: Pollutants
No full textThe densest network for measuring air pollutant concentrations in Colombia is in Medellin, where most sensors are located in the heavily polluted lower parts of the valley. Measuring stations in the higher elevations on the mountains surrounding the valley are not available, which limits our understanding of the valley’s pollutant dynamics and hinders the effectiveness of data assimilation studies using chemical transport models such as LOTOS-EUROS. To address this gap in measurements, we have designed a new network of low-cost sensors to be installed at altitudes above 2000 m.a.s.l. The network consists of custom-built, solar-powered, and remotely connected sensors. Locations were strategically selected using the LOTOS-EUROS model driven by diverse meteorology-simulated fields to explore the effects of the valley wind representation on the transport of pollutants. The sensors transmit collected data to internet gateways for posterior analysis. Various tests to verify the critical characteristics of the equipment, such as long-range transmission modeling and experiments with an R score of 0.96 for the best propagation model, energy power system autonomy, and sensor calibration procedures, besides case exposure to dust and water experiments, to ensure IP certifications. An inter-calibration procedure was performed to characterize the sensors against reference sensors and describe the observation error to provide acceptable ranges for the data assimilation algorithm (<10% nominal). The design, installation, testing, and implementation of this air quality network, oriented towards data assimilation over the Aburrá Valley, constitute an initial experience for the simulation capabilities toward the system’s operative capabilities. Our solution approach adds value by removing the disadvantages of low-cost devices and offers a viable solution from a developing country’s perspective, employing hardware explicitly designed for the situation

Effective elimination of fifteen relevant pharmaceuticals in hospital wastewater from Colombia by combination of a biological system with a sonochemical process
No full textThis work presents the treatment of selected emerging concern pharmaceuticals in real hospital wastewater (HWW) from Tumaco-Colombia by combination of a biological system with a sonochemical process. Fifteen compounds, commonly present in HWW, were considered: acetaminophen, diclofenac, carbamazepine, venlafaxine, loratadine, ciprofloxacin, norfloxacin, valsartan, irbesartan, sulfamethoxazole, trimethoprim, clarithromycin, azithromycin, erythromycin and clindamycin. Initially, HWW was characterized in terms of global parameters and the pharmaceuticals content. HWW contained a moderate amount of organic matter (i.e., total organic carbon: 131.56 mg L−1 (C)) mainly associated to biodegradable components. However, the most of pharmaceuticals were found at levels upper than their predicted no effect concentration (PNEC). Then, a conventional biological treatment was applied to the HWW. After 36 h, such process mainly removed biodegradable substances, but had a limited action on the pharmaceuticals. The resultant biotreated water was submitted to the sonochemical process (375 kHz and 88 W L−1, 1.5 h), which due to its chemical (i.e., radical attacks) and physical (i.e., suspended solids disaggregation) effects induced a considerable pharmaceuticals degradation (pondered removal: 58.82%), demonstrating the complementarity of the proposed combination. Afterwards, Fe2+ (5 ppm) and UVC light (4 W) were added to the sonochemical system (generating sono-photo-Fenton process), which significantly increased up to 82.86% the pondered pharmaceuticals removal. Subsequently, to understand fundamental aspects of the pharmaceuticals degradations, a model compound (norfloxacin) in distilled water was treated by sonochemical system, sono-photo-Fenton process and their sub-systems (i.e., sono-Fenton and UVC alone). This allowed proving the hydroxyl radical action in sonochemical treatment, plus the contribution of Fenton reaction and direct photodegradation in the pharmaceuticals removal by sono-photo-Fenton. Finally, it was found that 91.13% of the initial pharmaceuticals load in HWW was removed by the biological/sono-photo-Fenton combination. The high pollutants abatement evidenced that this combination is a powerful alternative for removing pharmaceuticals from complex-matrix waters, such as raw HWW
Wind Turbine Generator Condition Monitoring via the Generator Control Loop
No full textThis thesis focuses on the development of condition monitoring techniques for application in wind turbines, particularly for offshore wind turbine driven doubly fed
induction generators. The work describes the significant development of a physical condition monitoring Test Rig and its MATLAB Simulink model to represent modern variable speed wind turbine and the innovation and application of the rotor side control signals for the generator fault detection. Work has been carried out to develop a physical condition monitoring Test Rig from open loop control, with a wound rotor induction generator, into closed loop control with a doubly fed induction generator. This included designing and building the rotor side converter, installing the back-to-back converter and other new instrumentation. Moreover, the MATLAB Simulink model of the Test Rig has been developed to represent the closed loop control, with more detailed information on the Rig components and instrumentation and has been validated against the physical system in the time and frequency domains. A fault detection technique has been proposed by the author based on frequency analysis of the rotor-side control signals, namely; d-rotor current error, q-rotor current error and q-rotor current, for wind turbine generator fault detection. This technique has been investigated for rotor electrical asymmetry on the physical Test Rig and its MATLAB Simulink model at different fixed and variable speed conditions. The sensitivity of the each proposed signal has been studied under different operating conditions. Measured and simulated results are presented, a comparison with the results from using stator current and total power has been addressed and the improvement in condition monitoring detection performance has been demonstrated in comparison with previous methods, looking at current, power and vibration analysis
