Historischer Überblick zur mathematischen Theorie von Unstetigkeitswellen seit Riemann und Christoffel
1981
We give a brief historical account of the development of the mathematical theory of propagation of discontinuities in gases, fluids or elastic materials. The theory was initiated by Riemann who investigated the propagation of shocks in one-dimensional isentropic gas flow. Riemann’s results were used by Christoffel to treat, more generally, the propagation of (first order) discontinuity surfaces in three-dimensional flows of perfect fluids. Subsequently Christoffel applied his general theory to first order waves in certain elastic materials. Independently of Riemann and Christoffel significant contributions were made by Hugoniot. The theory was completed in Hadamard’s celebrated monograph [3…
The Riemannian manifold of all Riemannian metrics
1991
In this paper we study the geometry of (M, G) by using the ideas developed in [Michor, 1980]. With that differentiable structure on M it is possible to use variational principles and so we start in section 2 by computing geodesics as the curves in M minimizing the energy functional. From the geodesic equation, the covariant derivative of the Levi-Civita connection can be obtained, and that provides a direct method for computing the curvature of the manifold. Christoffel symbol and curvature turn out to be pointwise in M and so, although the mappings involved in the definition of the Ricci tensor and the scalar curvature have no trace, in our case we can define the concepts of ”Ricci like cu…
The Bread of God: religious and symbolic aspects of bakery
2019
Abstract The present conference discusses the symbolic meaning of bread in the religious mentality of the Ancient Near East. We will find that bread, besides being a food necessary for its existence, also represented a cultural archetype that summed up and assumed in itself either different divinities of Oriental civilizations, or had a ritual-sacrificial character, in order to facilitate man rather immortality.
Co-participation in Oral Paired Interviews: Preliminary Findings of the OPENPAU Project
2015
Abstract The Ministry of Education is changing how Spanish University Entrance Examination (PAU) will be delivered in 2017. To test the construct, experimental oral interviews with potential candidates of the PAU were done. Purpose of Study: The research observed whether paired interviews favored the delivery and organization of the PAU test and if this type of delivery favors the students’ performance. This paper studies how students in paired interviews outperform the individual. Sources of Evidence: About ten interviews were delivered in the US and about 40 in Spain. They all were recorded and analyzed from the interaction and output quality. Analysis and results: The study indicates tha…
Can the Students’ Career be Helpful in Predicting an Increase in Universities Income?
2013
The students’ academic failure and the delay in obtaining their final degree are a significant issue for the Italian universities and their stakeholders. Based on indicators proposed by the Italian Ministry of University, the Italian universities are awarded a financial incentive if they reduce the students’ attrition and failure. In this paper we analyze the students’ careers performance using: (1) aggregate data; (2) individual data. The first compares the performances of the Italian universities using the measures and the indicators proposed by the Ministry. The second analyzes the students’ careers through an indicator based on credit earned by each student in seven academic years. The …
Wildfire effects on extractable elements in ash from aPinus pinasterforest in Portugal

Brief an Karl Axel Christer Freiherr von Bruiningk
1839
Ms. 930a, Nr. 6b, Bl. 19r-19v Merkel, Garlieb H. Brief an Karl Axel Christer Freiherr von Bruiningk, [Depkinshof ?], [bez datuma; ohne Datum, pēc / nach 1839] Autora rokraksts / Autograph, vācu val. / Deutsch, [2] lpp. / S. Attēlu numuri / Bildnummern: 930a-006b-1 – 930a-006b-2 In dem undatierten Entwurf einer Antwort auf einen Brief Bruiningks [womit der unter Ms. 930a, Nr. 6a gemeint wird, bleibt noch unklar] lobt Merkel dessen Einsatz für die Bauernbefreiung. Das Problem des fehlenden Grundbesitzes für die freigelassenen Bauern sei ein Grund für die wirtschaftliche Rückständigkeit der „vaterländische[n] Provinzen“. Selbst in Posen (Preußen) und Galizien (Österreich) hätte die wirtschaftl…
Brief an Garlieb H. Merkel
1799
Ms. 930a, Nr. 18, Bl. 45r-46v Justus C. Loder. Brief an GarliebH. Merkel, Jena, den 19. Jul[i] 1799 Autora rokraksts / Autograph, vācuval. / Deutsch [2] lpp. / S. Attēlu numuri / Bildnummern: 930a-018-1, 930a-018-2 Der kurze Brief, der wahrscheinlich von Justus C. Loder stammt, hat vor allem zum Ziel, scheinbar erneut, Merkel einzuladen und die Verbundenheit mit ihm zum Ausdruck zu bringen.Loder, der zu diesem Zeitpunkt Professor für Medizin in Jena war, stammte aus Riga, woraus sich ein besonderes Verhältnis zu Livland und zum Adressaten entstammt haben könnte. Es ist naheliegend, dass Merkel während seines kurzen, aber nicht zu Ende geführten Medizinstudiums, das er in Leipzig begann und …
Ku teologicznemu pojęciu religii
2018
The concept of religion is a fundamental concept of religiological sciences. Still it is not devoid of difficulties. Its critics attempt to prove that plurality and variety of religious phenomena excludes the possibility to define religion. On the other hand the lack of the general concept of religion constitutes a serious problem for theology of religion since it is difficult to study relationships between Christianity and other religions not knowing what religion is and what its theological essence is. The present article consists of three parts. The first part analyses the history of the concept of religion (Latin religio). Second part considers the problem of the definition of religion.…
El litigio climático ante la responsabilidad intergeneracional
2021
El carácter intergeneracional del litigio climático plantea un interés sobre la protección jurídica de las generaciones futuras. La preocupación intergeneracional no es novedosa en el Derecho, sin embargo, debido al ascendiente número de litigios climáticos presentados por jóvenes en nombre propio y en el de las generaciones futuras para demandar mayor ambición climática han incorporado nuevas formas de observar este fenómeno. En esta contribución se lleva a cabo un estudio sobre sus implicaciones, la relevancia que puede tener el reconocimiento en normas internacionales e internas de los vínculos intergeneracionales, y cómo, a través del litigio climático, es posible vislumbrar nuevas form…
