Numerical relativity simulations of tilted black hole-torus systems
2016
Las fusiones de objetos compactos se encuentran entre los eventos más interesantes de la astrofísica relativista, siendo, en particular, el principal objetivo de la astronomía de ondas gravitatorias. En esta tesis investigamos los posibles estados finales de la fusión de sistemas binarios formados por agujero negro-estrella de neutrones o por dos estrellas de neutrones: discos gruesos (o toros) de acrecimiento alrededor de agujeros negros en rotación tipo Kerr. Estos sistemas agujero negro-toro se cree que constituyen el motor central de los eventos más luminosos del Universo: los llamados estallidos de rayos gamma. Nuestro conocimiento sobre la evolución y la estabilidad de estos sistemas …

Combined Analysis of the Effects of Exposure to Blue Light in Ducks Reveals a Reduction in Cholesterol Accumulation Through Changes in Methionine Met…
2021
Monochromatic light is widely used in industry, medical treatment, and animal husbandry. Green-blue light has been found to stimulate the proliferation of satellite cells and the results of studies on the effects of blue light on poultry vary widely. It would be worthwhile to study the effect of blue light on poultry growth and how exposure to blue light affects metabolism and the intestinal microbiota. In this study, we irradiated Cherry Valley ducks with 460 nm wavelength light (blue light) for 3 weeks to explore the effects of blue light in comparison to those of white light (combined wavelength light) on animal growth and development. Our results showed that, under exposure to blue ligh…

Ārstu izvēle izrakstot hipolipidēmiskos līdzekļus pacientiem un to patēriņš Latvijā salīdzinājumā ar Baltijas valstīm
2016
Kardiovaskulārās slimības ir biežākais nāves cēlonis gandrīz visās Eiropas Savienības valstīs. Sirds išēmiskās slimības ir izraisījušas aptuveni 18% no visiem nāves gadījumiem ES 2011. gadā. Viens no SIS attīstības cēloņiem ir hiperholesterinēmija. Statīni ir visbiežāk izrakstītās zāles holesterīna līmeņa samazināšanai, un to patēriņš ar katru gadu pieaug. Maģistra darba mērķis bija izpētīt ārstu izvēli izrakstot seruma lipīdu modificējošos līdzekļus, to apriti “Mēness aptiekā”, statīnus lietojošo pacientu veselību ietekmējošos paradumus un statīnu patēriņu Latvijā, salīdzinājumā ar Baltijas valstīm, veicot ārstu un pacientu aptaujas, kā arī veicot recepšu un patēriņa analīzi. Pētījumā tika…

Towards an understanding of the caring phenomenon - why is it so topical? : a search for its role and its attributes in holistic education
2016
Traditional liberal education has provided one-size-fits-all schooling, followed by neoliberal policies in the past 30 years, resulting in losing the purpose of education to build well-rounded personalities and to ensure quality education for all. Instead, the ideal today is the homo economicus able to further personal goals on self-interest, and the global divide between the haves and have-nots has increased. The research problem rises from the alternative view to the purpose of education, to fostering the learner’s full human growth, and focuses on holistic education as expressed in the ethics of care theory of Nel Noddings and my life experiences in four diverse learning cultures. Meta-a…
Management of labyrinthine fistula in chronic otitis with cholesteatoma: case series.
2015
Labyrinthine fistula is a complication of ear cholesteatoma that increase the risk of sensorineural hearing loss. The management of the fistula must be done contextually with mastoidectomy by: leaving cholesteatoma matrix over the fistula, or remove the matrix reconstructing the defect. Objective: analysis of the two techniques to treat labyrinthine fistula. Methods: retrospective review with case series analysis. Results: a labyrinthine fistula was present in 14% of cholesteatoma patients; CT scan was pre-dictive in all cases; the hearing preservation was obtained with both techniques; a re-currence was detected only in one case; postoperative nystagmus incidence was higher in those cases …
Geophysical study of an landslide in northern Sicily
2002
The San Fratello area in the Nebrodi Mountains (northern Sicily) is a region of high instability. It has suffered many devastating occurrences, which have hit and destroyed the village of San Fratello. At present the area is still subject to a high landslide risk. A series of geophysical surveys have been carried out with the aim of determining the thickness and dimensions of the landslide body as well as some tectonic features, in order to gain insight into the evolution of the landslide. The following geophysical techniques have been used: borehole seismic tomography, i.e. down-hole tomographic seismic soundings (DH TSS), time-domain electromagnetic (TDEM) soundings and georadar profiling…
Integration of constrained electrical and seismic tomographies to study the landslide affecting the cathedral of Agrigento
2014
The Cathedral of Saint Gerland, located on the top of the hill of Agrigento, is an important historical church, which dates back to the Arab–Norman period (XI century). Unfortunately throughout its history the Cathedral and the adjacent famous Archaeological Park of the 'Valley of the Temples' have been affected by landslides. In this area the interleaving of calcarenites, silt, sand and clay is complicated by the presence of dislocated rock blocks and cavities and by a system of fractures partly filled with clay or water. Integrated geophysical surveys were carried out on the north side of the hill, on which the Cathedral of Agrigento is founded, to define lithological structures involved …
