La expropiación de los bienes de las obras pías en Costa Rica, 1805-1860. Un capitulo en la consolidación económica de una élite nacional

IntroducciónEl presente estudio tratara de cumplir con dos propósitos fundamentales que son: la presentación de  varios documentos que consideramos son centrales en el proceso histórico costarricense en la época tardía de  la colonia y en los primeros años de la independencia y el análisis del Apple del sector ganadero de la época, a través de las cofradías ganaderas, en la consolidación de una elite económica nacional antes del cultivo comercial del café, punto de que hemos profundizado en otras ocasiones. Esta consolidación de grupo tuvo una de sus máximas expresiones en los distintos procesos e expropiación de las cofradías y obras pías ganaderas y traspaso a  mano particulares, primero bajo la consolidación de vales reales, llevada a  cabo por los años 1805-1890 por  orden de  la corona española y luego bajo sucesivas admistraciones independientes, hasta aproximadamente 1860.

Comentario del libro ‘El Río San Juan en la lucha de las Potencias, 1821-1860’

IntroducciónLa nueva obra de Clotilde Obregón Quesada constituye un aporte esclarecedor no sólo para los estudiosos de la historia de las relaciones internacionales de la Centroamérica del siglo pasado, sino también para todos quienes se interesan por el desarrollo político del Istmo en la hora actual. En efecto, si bien la temática del libro gira en torno a las complejas relaciones de poder expresadas en la lucha por la hegemonía sobre el río San Juan y la Vía del Tránsito a mediados del siglo XIX, también ofrece una interesante explicación sobre la naturaleza y significación de las tensiones que, desde entonces, prevalecen en el área...

Una lluvia de males: el régimen de precipitaciones en la Costa Rica del progreso. Trayectoria, representaciones sociales e impacto socioeconómico (1860-1940)

Resumen Este artículo procura establecer algunas de las múltiples interacciones posibles, entre la evolución de las precipitaciones, como uno de los factores climáticos de mayor incidencia histórica en las sociedades humanas, y la dinámica económica y socioambiental de Costa Rica, en un período en el que, al tiempo que se consolidaba como Estado-Nación y se definía de forma definitiva su rol agroexportador en el mercado mundial, se construían nuevas relaciones con el medio biofísico, guiadas por la dominante e incuestionable ideología del ?progreso?. Además de la dimensión objetiva del impacto de las lluvias, el trabajo procura realizar un breve repaso por las representaciones dominantes de este factor climático, frecuentemente dicotómicas y a la vez ambivalentes, como lo deja entrever el carácter ?bondadoso? o ?malsano? que a las lluvias y sus consecuencias, otorgaron diversos sujetos histórico-sociales. Abstract This papers analyses the relationship between the evolution of rainfalls and economic and socioenvironmental dynamism in Costa Rica in a period of State-building process, the consolidation of global economic exchange, and the definition of new relations with the environment, all guided by the ?progress? ideology. Besides analyzing the real impact of rainfall, this essay studies the major social representations of rainfall and its characterization by a diversity of historical subjects.

A IMPLANTAÇÃO FERROVIÁRIA NO ESTADO DO RIO DE JANEIRO: 1854-1898

Esse artigo é parte da pesquisa que pretende analisar a importância da ferrovia para a circulação na região Norte Fluminense do Estado do Rio de Janeiro. A pesquisa, ainda não concluída, está baseada nos preceitos da Geografia Histórica (ver SILVA, 2008). Com isso é necessário analisar o processo maior de implantação ferroviária no Estado do Rio de Janeiro desde o início da implantação ferroviária, em 1854, da primeira ferrovia brasileira, a Imperial Companhia de Navegação a Vapor e Estrada de Ferro de Petrópolis. A partir daí surge a Ferrovia Dom Pedro II, uma das mais importantes do país e depois a Estrada de Ferro Cantagalo. São então implantadas diversas ferrovias, sempre atendendo à interesses regionais capitaneados por lideranças locais. Assim é que a ferrovia chega em Campos dos Goytacazes em 1875. Outra importante ferrovia do estado foi a Estrada de Ferro Leopoldina, que foi incorporando várias pequenas linhas férreas, até a transformação desta ferrovia em outra empresa a “The Leopoldina Railway Company”, que começa a funcionar em 1898, substituindo o caos reinante na companhia anterior. O conhecimento do período inicial de configuração de uma rede ferroviária no Norte Fluminense passa a ser de fundamental importância devido à importância da Companhia Leopoldina para a região Norte Fluminense em períodos posteriores.

Development and use of clinical guidelines

The purpose of this chapter is to provide an overview of the development and use of clinical guidelines as a tool for decision making in clinical practice. Nurses have always developed and used tools to guide clinical decision making related to interventions in practice. Since Florence Nightingale (Nightingale 1860) gave us ‘notes’ on nursing in the late 1800s, nurses have continued to use tools, such as standards, policies and procedures, protocols, algorithms, clinical pathways and clinical guidelines, to assist them in making appropriate decisions about patient care that eventuate in the best desired patient outcomes. Clinical guidelines have enjoyed growing popularity as a comprehensive tool for synthesising clinical evidence and information into user-friendly recommendations for practice. Historically, clinical guidelines were developed by individual experts or groups of experts by consensus, with no transparent process for the user to determine the validity and reliability of the recommendations. The acceptance of the evidence-based practice (EBP) movement as a paradigm for clinical decision making underscores the imperative for clinical guidelines to be systematically developed and based on the best available research evidence. Clinicians are faced with the dilemma of choosing from an abundance of guidelines of variable quality, or developing new guidelines. Where do you start? How do you find an existing guideline to fit your practice? How do you know if a guideline is evidence-based, valid and reliable? Should you apply an existing guideline in your practice or develop a new guideline? How do you get clinicians to use the guidelines? How do you know if using the guideline will make any difference in care delivery or patient outcomes? Whatever the choice, the challenge lies in choosing or developing a clinical guideline that is credible as a decision-making tool for the delivery of quality, efficient and effective care. This chapter will address the posed questions through an exploration of the ins and outs of clinical guidelines, from development to application to evaluation.

Victoria regia's bequest to modern architecture

This paper will explore the relationship between the giant South American waterlily, the Victoria regia (today named Victoria amazonica), and the 1914 Glashaus exposition building by the German architect, Bruno Taut. Starting with a general botanical introduction of Victoria regia, the paper exposes the first European cultivation of the lily by Joseph Paxton at Chatsworth,England, in 1849. Following this initial cultivation, Paxton subsequently develops a specialist greenhouse for the plant, that later becomes the prototype for all Victoria regia greenhouses. However, from about 1860 as Victoria regia cultivation spreads to continental Europe, a greenhouse that differs from Paxton’s prototype subsequently evolves. An investigation of these later continental European greenhouses, coupled with an exposure of Taut’s own writings concerning Victoria regia, reveals startling similarities to the Glashaus, which ultimately reveals the Glashaus as directly inspired by Victoria regia.

Heritage refurbishment : National Trust House (Basement 3) [Architectural Practice Academy Office]

The refurbishment of The National Trust House (Basement3), undertaken in 2005, represents heritage consultation, architectural and interior design of a disused and deteriorating subbasement of a historically and culturally significant building situated in Brisbane. Research into rectification and restoration work of the existing structure and interior surfaces (inclusive of masonry work sourced from the Kangaroo Point quarry in the 1860's) formed a significant component of the project. The National Trust House sub basement 3 was refurbished to house the Architectural Practice Academy, a joint initiative of the Queensland Government and the Australian Institute of Architects.

Hydrogen-bonding in the structures of the hydrated proton-transfer compounds of isonipecotamide with the isomeric indole-2 and indole-3-carboxylic acids

The structures of two hydrated proton-transfer compounds of 4-piperidinecarboxamide (isonipecotamide) with the isomeric heteroaromatic carboxylic acids indole-2-carboxylic acid and indole-3-carboxylic acid, namely 4-carbamoylpiperidinium indole-2-carboxylate dihydrate (1) and 4-carbamoylpiperidinium indole-3-carboxylate hemihydrate (2) have been determined at 200 K. Crystals of both 1 and 2 are monoclinic, space groups P21/c and P2/c respectively with Z = 4 in cells having dimensions a = 10.6811(4), b = 12.2017(4), c = 12.5456(5) Å, β = 96.000(4)o (1) and a = 15.5140(4), b = 10.2908(3), c = 9.7047(3) Å, β = 97.060(3)o (2). Hydrogen-bonding in 1 involves a primary cyclic interaction involving complementary cation amide N-H…O(carboxyl) anion and anion hetero N-H…O(amide) cation hydrogen bonds [graph set R22(9)]. Secondary associations involving also the water molecules of solvation give a two-dimensional network structure which includes weak water O-H…π interactions. In the three-dimensional hydrogen-bonded structure of 2, there are classic centrosymmetric cyclic head-to-head hydrogen-bonded amide-amide interactions [graph set R22(8)] as well as lateral cyclic amide-O linked amide-amide extensions [graph set R24(8)]. The anions and the water molecule, which lies on a twofold rotation axis, are involved in secondary extensions.

Thomas Young’s investigations in gradient-index optics

Purpose: James Clerk Maxwell is usually recognized as being the first, in 1854, to consider using inhomogeneous media in optical systems. However, some fifty years earlier Thomas Young, stimulated by his interest in the optics of the eye and accommodation, had already modeled some applications of gradient-index optics. These applications included using an axial gradient to provide spherical aberration-free optics and a spherical gradient to describe the optics of the atmosphere and the eye lens. We evaluated Young’s contributions. Method: We attempted to derive Young’s equations for axial and spherical refractive index gradients. Raytracing was used to confirm accuracy of formula. Results: We did not confirm Young’s equation for the axial gradient to provide aberration-free optics, but derived a slightly different equation. We confirmed the correctness of his equations for deviation of rays in a spherical gradient index and for the focal length of a lens with a nucleus of fixed index surrounded by a cortex of reducing index towards the edge. Young claimed that the equation for focal length applied to a lens with part of the constant index nucleus of the sphere removed, such that the loss of focal length was a quarter of the thickness removed, but this is not strictly correct. Conclusion: Young’s theoretical work in gradient-index optics received no acknowledgement from either his contemporaries or later authors. While his model of the eye lens is not an accurate physiological description of the human lens, with the index reducing least quickly at the edge, it represented a bold attempt to approximate the characteristics of the lens. Thomas Young’s work deserves wider recognition.

Direct evaluation of IEC 61850-9-2 process bus network performance

This letter presents a technique to assess the overall network performance of sampled value process buses based on IEC 61850-9-2 using measurements from a single location in the network. The method is based upon the use of Ethernet cards with externally synchronized time stamping, and characteristics of the process bus protocol. The application and utility of the method is demonstrated by measuring latency introduced by Ethernet switches. Network latency can be measured from a single set of captures, rather than comparing source and destination captures. Absolute latency measures will greatly assist the design testing, commissioning and maintenance of these critical data networks.

Malnutrition in a sample of community-dwelling people with Parkinson’s disease

Objective: Malnutrition results in poor health outcomes, and people with Parkinson’s disease may be more at risk of malnutrition. However, the prevalence of malnutrition in Parkinson’s disease is not yet well defined. The aim of this study is to provide an estimate of the extent of malnutrition in community-dwelling people with Parkinson’s disease. Methods: This is a cross-sectional study of people with Parkinson’s disease residing within a 2 hour driving radius of Brisbane, Australia. The Subjective Global Assessment (SGA) and scored Patient Generated Subjective Global Assessment (PG-SGA) were used to assess nutritional status. Body weight, standing or knee height, mid-arm circumference and waist circumference were measured. Results: Nineteen (15%) of the participants were moderately malnourished (SGA-B). The median PG-SGA score of the SGA-B group was 8 (4 – 15), significantly higher than the SGA-A group, U=1860.5,p<.05. The symptoms most influencing intake were loss of appetite, constipation, early satiety and problems swallowing. Conclusions: As with other populations, malnutrition remains under-recognised and undiagnosed in people with Parkinson’s disease. Regular screening of nutritional status in people with Parkinson’s disease by health professionals with whom they have regular contact should occur to identify those who may benefit from further nutrition assessment and intervention.

Shape-formed ceramic superconductors by slip-casting

In order to rigorously test emerging applications using prototypes and pilot designs, high temperature superconductor (HTS) materials must be fabricated into a variety of shapes in an economical manner. We have developed a simple, economical, ceramic slip-casting approach to form complex shaped monolithic HTS articles for which high bulk density has been achieved. The sintered articles exhibit good Meissner signal and consist of phase-pure HTSC phase. A low transport critical current density is observed and is explained on the basis of densification and grain growth. © 1995 The Metallurgical of Society of AIME.

Ab initio studies of hydrogen desorption from low index magnesium hydride surface

The low index Magnesium hydride surfaces, MgH2(0 0 1) and MgH2(1 1 0), have been studied by ab intio Density Functional Theory (DFT) calculations. It was found that the MgH2(1 1 0) surface is more stable than MgH2(0 0 1) surface, which is in good agreement with the experimental observation. The H2 desorption barriers vary depending on the crystalline surfaces that are exposed and also the specific H atom sites involved – they are found to be generally high, due to the thermodynamic stability of the MgH2 system, and are larger for the MgH2(0 0 1) surface. The pathway for recombinative desorption of one in-plane and one bridging H atom from the MgH2(1 1 0) surface was found to be the lowest energy barrier amongst those computed (172 KJ/mol) and is in good agreement with the experimental estimates.
