Una nueva mirada al informe de la Ley Agraria de Jovellanos doscientos años después
1995
Con motivo del bicentenario (1795-1995) de la publicación del Informe de Ley Agraria de Jovellanos se presenta una visión retrospectiva de esa obra ya clásica del pensamiento español incluyendo un repaso de sus múltiples y desacordes intérpretes modernos y un análisis del interior del texto e incluso del título. Se concluye insistiendo en la plena inserción del Informe en la tradición ilustrada española, en que los usuales calificativos de mercantilista, liberal smithiano o fisiócrata son inadecuados y en que es preciso restituir la obra y su autor a su tiempo. On the occasion of the bicentenary (1795-1995) of the publication oMepart antbe AgraHan Law by Jovellanos, we present a retrospecti…

Quantum Spin-Tunneling:A Path Integral Approach
1995
We investigate the quantum tunneling of a large spin in a crystal field and an external magnetic field. The twofold degeneracy of the corresponding classical ground state is removed due to tunneling. The tunnel splitting ΔE o of the ground state is calculated by use of a path integral formalism. It is shown that coherent spin state path integrals do not yield a reasonable result. However a “bosonlzation” of the spin system yields excellent results in the semiclassical limit. This result follows from the coherent spin state approach from replacing the spin quantum number s by s + 1/2 which causes a renormalization of the preexponential factor of ΔE o .

La Generalitat Valenciana y las políticas de bienestar social (1985-1995)
1995
El Gobierno Autónomo se ha convertido en los últimos diez años en el principal proveedor de servicios públicos para la población valenciana. La educación, la salud y los servicios sociales son las tres principales áreas de actuación de la administración. A lo largo de estos diez últimos años se ha producido una mejora sustancial no sólo en el volumen global de gasto, sino también en la calidad del servicio, pese a que lo largo de este periodo la administración ha debido enfrentarse a nuevos desafíos como la LOGSE o la LRU.
Spatial Mark-Recapture Method in the Estimation of Crayfish Population Size
1995
The mark-recapture method is considered for estimation of population size of slowly moving animals like crayfish. The Petersen type estimator for closed population is generalized for situations where recaptures are spatially dependent between the capture sites, and its variance approximation is derived using point processes as models for the population. The method of quadratic forms is suggested to be used as variance estimator. Finally, a trapping design is proposed where onc trap at recapture is replaced by four adjacent traps. A simulation experiment is performed to explain the robusticity of the new trapping design against movements of animals.

Inclusive measurements of the K+- and p / anti-p production in hadronic Z0 decays
1995
This analysis, based on a sample of 170000 hadronic Z0 decays, provides a measurement of the K± and p/View the MathML source differential cross sections which is compared to string- and cluster fragmentation models. The total multiplicities for K± and p/View the MathML source per hadronic event were found to be: NK = 2.26 ± 0.18 and Np = 1.07 ± 0.14. The positions ξ* of the maxima of the differential cross sections as a function of ξ = ln(1/xp) for K± and p/View the MathML source were determined to be 2.63 ± 0.07 and 2.96 ± 0.16 respectively. A comparison of the ξ* values for various identified particles measured at LEP with the prediction of the Modified Leading Logarithm Approximation wit…
Results from the Real Photon Programme at MAMI
1995
The accelerator MAMI (Mainzer Mikrotron) with its excellent beam properties and its duty factor of 100% allows to apply coincidence techniques in intermediate energy nuclear physics, which has led to a variety of results with high precision. The real photon collaboration (A2) uses energy tagged bremsstrahlung photons with energies up to 800 MeV. We have results on total photon absorption (proton, deuteron, 3He and U), on Compton scattering (proton, 4He and 12C) and on meson production, especially on π°- and η-photoproduction. Double pion production on the proton and the deuteron was measured. The two and three body breakup of 3He was investigated as well as the reactions (γ,NN) and (γ, π ± …
From Theatre to Theatricality—How to Construct Reality
1995
At the end of the nineteenth century, the dominance of language, so typical of Western culture since the Renaissance, was increasingly challenged. As early as 1876, Nietzsche wrote on Richard Wagner in Thoughts Out of Season:He was the first to recognize an evil which is as widespread as civilization itself among men; language is everywhere diseased, and the burden of this terrible disease weighs heavily upon the whole of man's development. Inasmuch as language has retreated ever more and more from its true province— the expression of strong feelings, which it was once able to convey in all their simplicity—and has always had to strain after the practically impossible achievement of communi…
Vulnerability of Mediterranean ecosystems to Climatic Change, study of soil degradation under different climatological conditions in an altitudinal t…
1995
Abstract To investigate the potential response of soils to climatic change, measurements of soil physical and chemical properties were carried out during a year in a mountain zone in Alicante (Spain), along an altitudinal and climatological gradient. Hydrological properties (infiltration runoff and sediment concentration) were measured under winter and summer conditions. Chemical and physical soil properties were analyzed for reference soil profiles along the transect. The erosional response of the soils as well as soil properties like organic matter and CEC are found to be under the direct influence of the climate, and as a result they have to be considered as important factors in the dese…
Effects of Cytokines on the Expression of Cell Adhesion Molecules by Cultured Human Omental Mesothelial Cells
1995
Cultured mesothelial cells (HOMES) are very responsive to the proinflammatory cytokines, interleukin (IL)-1 and tumor necrosis factor-alpha (TNF-alpha). E-selectin, ICAM-1 and VCAM-1 are known to play an important role, because they are presented by diverse cell types, for example endothelial cells (ECs), and interact with co-responding ligands on white blood cell membranes. In this study, the expression of ICAM-1, VCAM-1, E-selectin as well as PECAM-1 on cultured HOMES was studied over 5, 24, 48 and 72 h exposure to IL-1 beta, interferon-gamma and TNF-alpha. In previous studies we have shown that IL-1 beta and TNF-alpha increase the expression of ICAM-1, E-selectin and VCAM-1 on the cytopl…
Renormalization of the effective theory for heavy quarks at small velocity
1995
The slope of the Isgur-Wise function at the normalization point, $\xi^{(1)}(1)$,is one of the basic parameters for the extraction of the $CKM$ matrix element $V_{cb}$ from exclusive semileptonic decay data. A method for measuring this parameter on the lattice is the effective theory for heavy quarks at small velocity $v$. This theory is a variant of the heavy quark effective theory in which the motion of the quark is treated as a perturbation. In this work we study the lattice renormalization of the slow heavy quark effective theory. We show that the renormalization of $\xi^{(1)}(1)$ is not affected by ultraviolet power divergences, implying no need of difficult non-perturbative subtraction…
Organophosphonate utilization by the wild-type strain of Penicillium notatum
1995
We studied the biodegradation of compounds containing phosphorus-to-carbon bonds by using a wild-type strain of Penicillium notatum. The substrate specificity of this strain was studied, and we found that it is able to utilize structurally diverse organophosphonates as sole sources of phosphorus. This ability seems to be inducible, as indicated by the presence of a lag phase during growth. A popular herbicide, glyphosate, inhibited fungal growth, but it was also degraded by the fungus if it was applied in sublethal doses. This indicates that P. notatum may play an important role in biodegradation of organophosphonates. The strain which we used did not metabolize any of the phosphonates whic…
Feitzingerowie. Cieszyński epizod w historii polskiej książki masowej
1995
Printing industry has belonged, since the second half of the XIXth century to the best-developed industrial branches in Cieszyn Region. There appeared here a great number of active printing-editing centres in such places as the capital of the Region and Biała, but also in Bogumin, Frysztat or Ostrava. The modem local cultural goods market was co-created by the effectively working, multi-generation publishing company of the Feitzingers. It built its market offer, first of all, from what might enjoy the easiest sales. Edward, the son, printed, for example, all sorts of calendars, well-selling and profit-yielding Series of folk booklets, books designed for followers of two Christian denominati…

Fracturas de cadera y diáfisis femoral ipsilaterales
1995
Se aportan 10 casos de fracturas de cadera y diáfisis femoral ipsilaterales tratados quirúrgicamente de forma diferida con un tiempo medio de demora de 12 días (rango: 3 a 22 días). Nueve fracturas diafisarias fueron tratadas con placa AO de fémur, y una, donde la fractura de cadera asociada pasó inicialmente inadvertida, mediante un clavo de Küntscher. Las fracturas de cadera se fijaron con tornillos de esponjosa (8 casos) o clavo-placa de Richards (2 casos). En todos los pacientes se inició un programa de rehabilitación precoz. El seguimiento medio ha sido de 31 meses (rango: 12 a 84 meses). Todas las fracturas consolidaron. Las complicaciones fueron un caso de acortamiento femoral y otro…
Optimización de las osteotomías de tibia mediante cálculos matemáticos
1995
El objetivo de este trabajo es aclarar con cálculos matemáticos las dificultades que existen en cuanto a la relación entre la cuña a resecar con la desviación a corregir y los diferentes alargamientos según que las osteotomías sean cuneiformes o bien arciformes. Así hemos llegado a las siguientes conclusiones: 1) Se ha establecido una fórmula matemática que nos permite obtener una relación exacta entre la cuña a resecar y la desviación a corregir; 2) Se demuestra el importante rol que juega el ancho de la metáfisis como factor relevante en la cuña a resecar; 3) Las osteotomías cuneiformes producen un acortamiento real del hueso, que se ve compensado con la corrección del eje del mismo; 4) L…

La figura de Sócrates en el joven Nietzsche
1995
Detallada exposición de los diferentes significados que reviste la figura de Sócrates en la obra del joven Nietzsche, en especial en 'El nacimiento de la tragedia', obra en la que tanto el motivo de Sócrates moribundo, como de Sócrates cultivando la música, permiten una lectura mucha más matizada del pretendido tópico maniqueo que opone sin más a Sócrates con Dionisos.

Peroxisomes and Hepatotoxicity
1995
Peroxisomes are ubiquitous organelles of eukaryotic cells and are present in significant amounts in hepatic liver cells. Peroxisomal enzymes contribute to several metabolic pathways including fatty acid, purine and amino acid catabolism or bile acid synthesis. The peroxisomal oxidative reactions produce hydrogen peroxide, mostly degraded by catalase which prevents oxidative stress. Moreover, peroxisomes are involved in arylderivative drug detoxification through its epoxide hydrolase activity.
The structure of gas-filled n-butyl-2-cyanoacrylate (BCA) polymer particles
1995
Abstract The structure of gas-filled poly-[n-butyl-2-cyanoacrylate] (BCA) particles has been demonstrated by negative staining with uranyl acetate, platinum-carbon shadowing of air-dried material and thin sectioning of the aqueous suspension of BCA particles, embedded in water-soluble melamine resin. The polymer shell of the hollow particles possesses a globular outer surface and a smoother inner surface.
On the construction of classes of suffix trees for square matrices: Algorithms and applications
1995
Given an n × n TEXT matrix with entries defined over an ordered alphabet σ, we introduce 4n−1 classes of index data structures for TEXT. Those indices are informally the two-dimensional analog of the suffix tree of a string [15], allowing on-line searches and statistics to be performed on TEXT. We provide one simple algorithm that efficiently builds any chosen index in those classes in O(n2 log n) worst case time using O(n2) space. The algorithm can be modified to require optimal O(n2) expected time for bounded σ.
Genetic Heterogeneity and Phenotype Variation of Schizophrenia
1995
It is well proven that the manifestation of schizophrenia is under genetic control (Kendler and Diehl 1993). It is however less clear: 1. How relevant environmental factors are, and how they operate and interact with genetic factors. 2. If the genetic susceptibility is identical across the total population of schizophrenics (or at least across all subjects with familial schizophrenia), or if the specific genetic components vary across families. 3. What is transmitted in families of schizophrenics and how co-familial traits are related to genetic and genetic risk factors; are only disorders and symptoms that belong to the schizophrenic sepctrum transmitted or are neurophysiological, neuropsy…
Fibrosis glútea: ¿esencial o secundaria?
1995
Constatamos la rara frecuencia de esta afección presentando 5 observaciones de Fibrosis Glútea recogidas en tres casos clínicos estudiados. Dos son bilaterales y uno afecta a un solo glúteo. Habiéndose invocado, por los autores consultados, etiologías diversas, actualmente sigue siendo desconocida. Creemos de interés resaltar que los casos presentados se trataron en las etapas finales de crecimiento, mientras que los referidos en la literatura consultada todos han recibido tratamiento quirúrgico en edad temprana. El tratamiento es de resultado satisfactorio, independientemente de la edad y de la técnica quirúrgica empleada. Three patients affected with gluteal fibrosis are colected by the a…
