RESUMEN: Elaboro un ambiente para los sentidos, creando un lugar lleno de color, texturas, comodidad e incomodidad, dispuesto para activar los sentidos, sobre todo el sentido del erotismo y no partiendo desde el punto de vista morboso, sino mas bien mórbido; un erotismo romántico. No busca la producción del placer sexual como lo es la pornografía; sino mas bien un erotismo personal, más propio; donde se esta uno con sus pensamientos y hay malicia; por un instante logro desconéctame de la cotidianidad. La relación del objeto con la comida nace de la armonía que encuentro entre el comer y el sentir, sin embargo, no busco la representación literal de las cosas, es mas bien una metáfora sensorial donde cada quien le da un sentido desde su experienciaABSTRACT: I develop an environment for the senses, creating a place full of color, textures, comfort and discomfort, ready to activate the senses, especially the sense of eroticism and not starting from the morbid point of view, but rather morbid; a romantic eroticism. It does not seek the production of sexual pleasure as is pornography; but rather a personal eroticism, more proper; where you are one with your thoughts and there is malice; for an instant I manage to disconnect from everyday life. The relationship of the object with food is born from the harmony that I find between eating and feeling, however, I do not seek the literal representation of things, it is rather a sensory metaphor where everyone gives it a meaning from their experienc

Successful combination of electron spin resonance, luminescence and palaeomagnetic dating methods allows reconstruction of the Pleistocene evolution of the lower Moulouya river (NE Morocco)

Based on a combination of Electron Spin Resonance (ESR) dating of quartz, luminescence dating of K-feldspar and palaeomagnetism, this study presents the first chronostratigraphic framework for the Pleistocene fluvial deposits of the lower Moulouya river in the Triffa basin (NE Morocco). K-feldspar pIRIR(225) and pIRIR(290) signals of all samples are saturated, suggesting fluvial deposition at least as early as the Middle Pleistocene (similar to 0.39-0.80 Ma). Consequently, further chronological information was obtained with ESR dating of quartz grains from the ancient Pleistocene fluvial deposits. As for ESR, the multiple centres approach provides equivalent dose values derived from the Al and Ti centres that mostly agree within 1 sigma-error, suggesting complete signal resetting from the former during fluvial transport. ESR dating results yield Calabrian deposition ages for all river profiles from similar to 1.1 to similar to 1.5 Ma. These ages are remarkably consistent with the palaeomagnetic results: the occurrence of mostly reversed polarity in the deposits indicates a Matuyama age (>0.78 Ma). While low incision rates in the Triffa basin (0.025 +/- 0.003 mm/a) related to thrusting activity during the Calabrian could be inferred, the fluvial record points to an acyclic and discontinuous sedimentation pattern over the last similar to 1.3 Ma. It thereby probably rules out climate as the main driver for fluvial aggradation in the lowermost sedimentary basin. At a regional scale, several indicators point to transient fluvial response resulting from major Quaternary tectonic activity along the Beni Snassen gorge, located directly upstream of the investigated basin. We suggest that a capture event at the margin of the uplifting Beni Snassen massif occurred between 1.04 and 1.36 Ma at the latest and subsequently led to the creation of the gorge.

Chagas cardiomiopathy: the potential of diastolic dysfunction and brain natriuretic peptide in the early identification of cardiac damage

INTRODUCTION: Chagas disease remains a major cause of mortality in several countries of Latin America and has become a potential public health problem in non-endemic countries as a result of migration flows. Cardiac involvement represents the main cause of mortality, but its diagnosis is still based on nonspecific criteria with poor sensitivity. Early identification of patients with cardiac involvement is desirable, since early treatment may improve prognosis. This study aimed to assess the role of diastolic dysfunction, abnormal myocardial strain and elevated brain natriuretic peptide (BNP) in the early identification of cardiac involvement in Chagas disease. METHODOLOGY/PRINCIPAL FINDINGS: Fifty-four patients divided into 3 groups--group 1 (undetermined form: positive serology without ECG or 2D-echocardiographic abnormalities; N = 32), group 2 (typical ECG abnormalities of Chagas disease but normal 2D-echocardiography; N = 14), and group 3 (regional wall motion abnormalities, left ventricular [LV] end-diastolic diameter >55 mm or LV ejection fraction 37 pg/ml) were noted in 0%, 13%, 29% and 63% in controls and groups 1 to 3, respectively. Half of patients in the undetermined form had impaired relaxation patterns, whereas half of patients with ECG abnormalities suggestive of Chagas cardiomyopathy had normal diastolic function. In group 1, BNP levels were statistically higher in patients with diastolic dysfunction as compared to those with normal diastolic function (27 ± 26 vs. 11 ± 8 pg/ml, p = 0.03). CONCLUSION/SIGNIFICANCE: In conclusion, the combination of diastolic function and BNP measurement adds important information that could help to better stratify patients with Chagas disease

ENGIU: Encuentro Nacional de Grupos de Investigación de UNIMINUTO.

El desarrollo del prototipo para el sistema de detección de Mina Antipersona (MAP), inicia desde el semillero ADSSOF perteneciente al programa de Administración en Seguridad y Salud en el trabajo de la UNIMINUTO, se realiza a partir de un detector de metales que emite una señal audible, que el usuario puede interpretar como aviso de presencia de un objeto metálico, en este caso una MAP. La señal audible se interpreta como un dato, como ese dato no es perceptible a 5 metros de distancia, se implementa el transmisor de Frecuencia Modulada FM por la facilidad de modulación y la escogencia de frecuencia de transmisión de acuerdo con las normas y resolución del Ministerio de Comunicaciones; de manera que esta sea la plataforma base para enviar los datos obtenidos a una frecuencia establecida. La idea es que el ser humano no explore zonas peligrosas y buscar la forma de crear un sistema que permita eliminar ese riesgo, por otro lado, buscar la facilidad de uso de elementos ya disponibles en el mercado
