Libros de texto de matemáticas en España en los siglos XVIII y XIX

A finales del siglo XVIII, en Europa el conocimiento científico se había desarrollado extraordinariamente. Surgen los nombres de Lavoisier, Ritcher, Coulomb y Celsius entre otros muchos. Se enuncian leyes en química y física; junto a ellas también florece la matemática de la mano de Euler, Lagrange, D«Alambert, Monge, por citar sólo unos cuantos. Mientras tanto, el atraso de las matemáticas españolas se debía, entre otras causas, al pobre estado en que se encontraban las universidades: aún de tipo medieval y de carácter eclesiástico. Esto lo evidencia Fray Benito Jerónimo Feijoo en la carta titulada Causas del atraso que se padece en España en orden a las ciencias naturales, y el Marqués de la Ensenada quien, en 1748, se lo expresa al rey Fernando VI. Las deficiencias de las universidades tenían que ver con la enseñanza memorística, textos anticuados e interés primordial por disciplinas como derecho, teología y filosofía en detrimento de las matemáticas y las ciencias.

Problemas comentados (XIX)

Algunos problemas nos atraen independientemente de la dificultad de su resolución. El que vamos a presentar lleva como título ¿CÓMO SE LLAMA EL PROFE? Y lo hemos encontrado en el libro de Agustín Fonseca: “El rompecocos” (Ed. Temas de Hoy).

Reality Shows in Chile, origin and road map. Historical-Communication Dialogues

Reality shows are TV programs which represent a format used in television nowadays; however, the observation practices of individual and/or group intimacy dates from thousands years ago. Sometimes this was driven by voyeurism or morbid fascination, some others, by the purpose of guarding, supervising and maintaining status quo. This work offers an alternative answer to the explanation of this type of TV program emergence and relates this appearance to a government procedure bound up with modern State terrorism which began at the end of the eighteenth century and has been recalled by different regimes until present days.

Dirac-Fock energy levels and transition probabilities for oxygen-like Fe XIX

Multiconfigurational Dirac-Fock calculations are reported for 656 energy levels and the 214 840 electric dipole (E I), electric quadrupole (E2) and magnetic dipole (M1) transition probabilities in oxygen-like Fe xix. The spectroscopic notations as well as the total transition probabilities from each energy level are provided. Good agreement is found with data compiled by NIST.

Radiation damping effects on L-shell photoionization cross- sections of O-like Fe xix and N-like recombination rate coefficients for Fe xx

Photoionization cross-sections out of the fine-structure levels (2S(2)2p(4) P-3(2,0,1)) of the O-like Fe ion Fe XIX have been reinvestigated. Data for photoionization out of each of these finestructure levels have been obtained, where the calculations have been performed with and without the inclusion of radiation damping on the resonance structure in order to assess the importance of this process. Recombination rate coefficients are determined using the Milne relation, for the case of an electron recombining with N-like Fe ions (Fe XX) in the ground state to form O-like Fe (Fe XIX) existing in each of the fine- structure ground-state levels. Recombination rates are presented over a temperature range similar to 4.0 less than or equal to log T-e less than or equal to 7.0, of importance to the modelling of X-ray emission plasmas.

Effective collision strengths for transitions in Ni XIX

Aims. In this paper we report electron impact collision strengths and excitation rates for transitions among the lowest 89 levels of Ni XIX.
Methods. The Dirac atomic R-matrix code (DARC) is adopted for the calculations of collision strengths and subsequently the effective collision strengths.
Results. Collision strengths for resonance transitions among 89 levels arising from the (1s2) 2s22p6, 2s22p53$\ell$, 2s2p63$\ell$, 2s22p54$\ell$, and 2s2p64$\ell$ configurations of Ni XIX are reported over a wide energy range below 250 Ryd. Additionally, effective collision strengths for all 3916 transitions among the 89 levels are listed over a wide temperature range below 107 K. Comparisons are made among different calculations and the accuracy of the data is assessed. Finally, comparisons between theoretical and experimental intensity ratios of some prominent lines of Ni XIX are discussed.

Collision strengths for transitions in Ni XIX

In this paper we present calculations of electron impact excitation collision strengths for transitions among the 89 fine-structure levels of the 2S(2) 2p(,)(6) 2S(2) 2P(5) 3l, 2s(2)p(6) 3l, 2s(2) 2p(5) 4l, and 2s(2)p(6) 2l configurations of Ni XIX, for which flexible atomic code (FAC) has been adopted. Comparisons are made with the earlier available results in the literature, and the anomalies observed have been discussed.

Electron impact excitation collision strengths for neon-like Ni XIX calculated using the relativistic R-matrix method

In a recent paper [Pramana - J. Phys. 64, 129 (2005)] results have been presented for electron impact excitation collision strengths for transitions among the fine-structure levels of the 2s(2)2p(6) and 2s(2)2p(5)3s configurations of Ni XIX. In this paper we demonstrate through an independent calculation with the relativistic R-matrix code that those results are unreliable and the conclusions drawn are invalid.

Aims. In this paper we report calculations for energy levels and radiative rates for transitions in Ni XIX.

Energy levels, radiative rates and electron impact excitation rates for transitions in He-like Cl XVI, K XVIII, Ca XIX and Sc XX.

We report calculations of energy levels, radiative rates and electron impact excitation cross
sections and rates for transitions in He-like Cl XVI, K XVIII, Ca XIX and Sc XX. The grasp
(general-purpose relativistic atomic structure package) is adopted for calculating energy levels
and radiative rates. To determine the collision strengths and subsequently the excitation rates,
the Dirac atomic R-matrix code (darc) is used. Oscillator strengths, radiative rates and line
strengths are reported for all E1, E2, M1 and M2 transitions among the lowest 49 levels of
each ion. Collision strengths are averaged over a Maxwellian velocity distribution and the
effective collision strengths obtained listed over a wide temperature range up to 107.4 K.
Comparisons are made with similar data obtained from the flexible atomic code (fac) to
highlight the importance of resonances, included in calculations with darc, in the
determination of effective collision strengths. Discrepancies between the collision strengths
from darc and fac, particularly for forbidden transitions, are also discussed. Additionally,
theoretical lifetimes are listed for all the 49 levels of the above four ions.

Energy levels, radiative rates and electron impact excitation rates for transitions in Be-like Ti XIX

We report calculations of energy levels, radiative rates and electron impact excitation cross sections and rates for transitions in Be-like Ti XIX. The general-purpose relativistic atomic structure package is adopted for calculating energy levels and radiative rates. For determining the collision strengths and subsequently the excitation rates, the Dirac atomic R-matrix code (darc) is used. Oscillator strengths, radiative rates and line strengths are reported for all E1, E2, M1 and M2 transitions among the lowest 98 levels of the n≤ 4 configurations. Additionally, theoretical lifetimes are listed for all 98 levels. Collision strengths are averaged over a Maxwellian velocity distribution and the effective collision strengths obtained listed over a wide temperature range up to 10 ^7.7K. Comparisons are made with similar data obtained from the flexible atomic code (fac) to highlight the importance of resonances, included in calculations with darc, in the determination of effective collision strengths. Discrepancies between the collision strengths from darc and fac, particularly for forbidden transitions, are also discussed. 

O que o estado português quis conservar: a avaliação e aquisição de documentos de arquivo em Portugal nos séculos XIX e XX

Esta dissertação procura identificar os desígnios que orientaram as decisões do Estado português em relação à aquisição de documentos de arquivo, com o objectivo de verificar se esses desígnios se formalizaram numa política de avaliação e aquisição de documentos de arquivo coerente e sistemática. A análise incidiu no Arquivo Nacional e nos arquivos distritais durante o período cronológico que abrange o século XIX e a primeira metade do século XX. Partindo da discussão teórica presente nos discursos de arquivistas e investigadores, da evolução das práticas no Arquivo Nacional e das incorporações realizadas nos arquivos distritais, esta tese defende que existiu uma visão constitutiva dos arquivos enquanto repositórios documentais da memória da nação. No entanto, esta visão não se concretizou numa política arquivística articulada e estrutural; ABSTRACT:This dissertation aims to identify portuguese state’s goals that guided its intervention on acquisition of archival records. Our purpose is to verify if those goals meant a coherent and systematic appraisal and acquisition policy. Our analysis took as object Portugal’s national and regional archives from nineteenth to twentieth century’s first half. Beginning from theoretical discussion that can be seen on archivists and investigators speeches, National Archive’s practices and acquisitions occurred in regional archives, this thesis sustains that there was a vision on the archives as national memory documental repositories. However, this vision was not translated on an articulated and structured archival policy.
