El brigadier Juan Gutiérrez de la Concha y el papel de los marinos españoles en tiempos de la revolución rioplatense (1808-1814)

En la presente Tesis Doctoral se abarcan dos objetos de estudio principales y complementarios. El primero es de carácter individual: la vida del brigadier de la Real Armada Juan Gutiérrez de la Concha (1760-1810); mientras que el segundo es colectivo, y se refiere al papel de los marinos destinados en el Virreinato del Río de la Plata entre 1808 y 1814. Ese segundo eje de investigación está además conformado por diversos actores que en realidad se encuentran íntimamente relacionados. La investigación aborda desde una metodología biográfica, basada en la prosopografía, el análisis de la vida y trayectoria profesional de Gutiérrez de la Concha hasta su muerte por oponerse a la Junta revolucionaria de Buenos Aires (mayo de 1810), estudiando las páginas de la historia naval española de las que formó parte. El propósito ha sido entender su trayectoria vital como respuesta a un tiempo cultural (Ilustración – siglo XVIII), a un espacio geo-histórico preciso (España – Virreinato del Río de la Plata), a una formación específica (oficial naval), y a las características particulares que toda persona posee. Las fuentes documentales analizadas han sido numerosas, y tanto su procedencia como su tipología revisten una considerable variedad, encontrándose tanto en archivos españoles como en archivos americanos. Una diversidad que recoge aquella documentación directamente relacionada con la vida y profesión del personaje (acta de bautismo, partida de casamiento, hoja de servicios, expediente militar, memoria testamentaria…), hasta las fuentes de procedencia diversa que nos acercan igualmente a su conocimiento y al de la trayectoria profesional de sus camaradas (memorias de contemporáneos, correspondencia privada, documentos diversos, informes, memoriales, gacetas, correspondencia administrativa…) En los tiempos de la revolución rioplatense los marinos españoles tomaron en su mayoría el partido de oponerse a la misma, aunque no fue una actitud desarrollada de manera monolítica ni homogénea...

A REGIONALIZAÇÃO DO HIP HOP NO BRASIL SOB A ÓTICA DA GEOGRAFIA: HORIZONTALIDADES E VERTICALIDADES

O presente trabalho objetiva discutir o Hip Hop como manifestação territorial. Essa manifestação territorial assume particularidades regionais e tem no Rap uma das suas formas de existir. Carregado de regionalismo, o Rap tem influenciado, tanto por meio de suas reclamações quanto por meio de suas particularidades, na inclusão de uma parcela da população no exercício da política. O Hip Hop, que abrange uma grande quantidade de jovens e tem profundas ligações com os lugares, é utilizado como ferramenta de solidariedade orgânica, haja vista que essa manifestação assumiu uma posição bastante relevante frente a questões urgentes relacionadas a segmentos sociais desfavorecidos e fez também com que membros de um movimento não-institucional passassem a participar da política formal, concorrendo inclusive a cargos públicos.

Endoscopic Endonasal Transsphenoidal Resection Of Pituitary Adenomas: Preliminary Evaluation Of Consecutive Cases.

Endoscopic endonasal transsphenoidal surgery has gained increasing acceptance by otolaryngologists and neurosurgeons. In many centers throughout the world, this technique is now routinely used for the same indications as conventional microsurgical technique for pituitary tumors. To present a surgical experience of consecutive endoscopic endonasal trans-sphenoidal resections of pituitary adenomas. In this study, consecutive patients with pituitary adenomas submitted to endoscopic endonasal pituitary surgery were evaluated regarding the rate of residual tumor, functional remission, symptoms relief, complications, and tumor size. Forty-seven consecutive patients were evaluated; 17 had functioning adenomas, seven had GH producing tumors, five had Cushing's disease, and five had prolactinomas. Of the functioning adenomas, 12 were macroadenomas and five were microadenomas; 30 cases were non-functioning macroadenomas. Of the patients with functioning adenomas, 87% improved. 85% of the patients with visual deficits related to optic nerve compression progressed over time. Most of the patients with complaints of headaches improved (76%). Surgical complications occurred in 10% of patients, which included with two carotid lesions, two cerebrospinal fluid leaks, and one death of a patient with a previous history of complications. Endoscopic endonasal pituitary surgery is a feasible technique, yielding good surgical and functional outcomes, and low morbidity.

Low-density Three-dimensional Foam Using Self-reinforced Hybrid Two-dimensional Atomic Layers.

Low-density nanostructured foams are often limited in applications due to their low mechanical and thermal stabilities. Here we report an approach of building the structural units of three-dimensional (3D) foams using hybrid two-dimensional (2D) atomic layers made of stacked graphene oxide layers reinforced with conformal hexagonal boron nitride (h-BN) platelets. The ultra-low density (1/400 times density of graphite) 3D porous structures are scalably synthesized using solution processing method. A layered 3D foam structure forms due to presence of h-BN and significant improvements in the mechanical properties are observed for the hybrid foam structures, over a range of temperatures, compared with pristine graphene oxide or reduced graphene oxide foams. It is found that domains of h-BN layers on the graphene oxide framework help to reinforce the 2D structural units, providing the observed improvement in mechanical integrity of the 3D foam structure.

Correlation Between Cephalometric Data And Severity Of Sleep Apnea.

Obstructive sleep apnea syndrome has a high prevalence among adults. Cephalometric variables can be a valuable method for evaluating patients with this syndrome. To correlate cephalometric data with the apnea-hypopnea sleep index. We performed a retrospective and cross-sectional study that analyzed the cephalometric data of patients followed in the Sleep Disorders Outpatient Clinic of the Discipline of Otorhinolaryngology of a university hospital, from June 2007 to May 2012. Ninety-six patients were included, 45 men, and 51 women, with a mean age of 50.3 years. A total of 11 patients had snoring, 20 had mild apnea, 26 had moderate apnea, and 39 had severe apnea. The distance from the hyoid bone to the mandibular plane was the only variable that showed a statistically significant correlation with the apnea-hypopnea index. Cephalometric variables are useful tools for the understanding of obstructive sleep apnea syndrome. The distance from the hyoid bone to the mandibular plane showed a statistically significant correlation with the apnea-hypopnea index.

Sinonasal Disorders In Hematopoietic Stem Cell Transplantation.

hematopoietic stem cell transplantation (HSCT) is associated with more respiratory infections due to immunosuppression. this study aimed to verify the frequency of rhinosinusitis after HSCT, and the association between rhinosinusitis and chronic graft vs. host disease (GVHD) and type of transplantation, clinical treatment, surgical treatment, and survival. this was a retrospective study in a tertiary university hospital. A total of 95 patients with hematological diseases undergoing HSCT between 1996 and 2011 were selected. chronic myeloid leukemia was the most prevalent disease. The type of transplant most often performed was the allogenic type (85.26%). The frequency of rhinosinusitis was 36%, with no difference between the autologous and the allogenic types. Chronic GVHD occurred in 30% of patients. Patients with GVHD had a higher frequency and recurrence of rhinosinusitis, in addition to more frequent need for endoscopic sinusectomy and decreased overall survival. there was a higher frequency of rhinosinusitis in HSCT and GVHD. The type of transplant does not appear to predispose to the occurrence of rhinosinusitis. GVHD seems to be an aggravating factor and requires a more stringent treatment.

Histologic Correlation Of Expression Of Ki-67 In Squamous Cell Carcinoma Of The Glottis According To The Degree Of Cell Differentiation.

Squamous cell carcinoma is the most common neoplasm of the larynx and glottis, and its prognosis depends on the size of the lesion, level of local invasion, cervical lymphatic spread, and presence of distant metastases. Ki-67 (MKI67) is a protein present in the core, whose function is related to cell proliferation. To evaluate the expression of marker Ki-67 in squamous cell carcinoma of the larynx and glottis and its correlation to pathological findings. Experimental study with immunohistochemistry analysis of Ki-67, calculating the percentage of the cell proliferation index in glottic squamous cell carcinomas. Sixteen cases were analyzed, with six well-differentiated and 10 poorly/moderately differentiated tumors. There was a correlation between cell proliferation index and degree of cell differentiation, with higher proliferation in poorly/moderately differentiated tumors. The cell proliferation index, as measured by Ki-67, may be useful in the characterization of histological degree in glottic squamous cell tumors.
