Abstract. This paper is devoted to the development of a methodology suitable to be used to determine the impact of of wind farms in distribution networks that are also supplied with other classical generation facilities based on thermal and hydraulic energy. The methodology is based on an automated analysis varies the level of the electric generation for both the and thermal generators by using PSS, Phyton user can define multiple scenarios considering wind, thermal and hydraulic generators so the line capacity can be computed and compared in order to know where the system located and which situations occur. All the results computed can be analysed in a single or compared way by using tables and plots and considering the static rate of the distribution lines. The developed system can also be applied to the computation of the sensitivity of the power flow to the variation of the parameters that define the power system

Evaluación de un aerogenerador nacional de baja potencia empleando metodología de análisis de ciclo de vida

Actualmente se producen y comercializan en el país aerogeneradores de baja potencia que en general no cuentan con una evaluación de su impacto ambiental. En este trabajo se estudia el impacto ambiental de producir un aerogenerador de 1,3 kW mediante un análisis de ciclo de vida (ACV). Se procedió a realizar un inventario de todos los materiales y procesos consumidos en la fabricación, para desarrollar su ciclo de vida y analizarlo posteriormente. Como conclusiones se puede resaltar que los materiales y/o procesos de fabricación asociados a la fabricación de la torre y el generador son los que más contribuyen al impacto total calculado, que principalmente producirá daños potenciales sobre la salud humana, en menor medida sobre los recursos naturales y por último en la calidad de los ecosistemas, de acuerdo al método de análisis seleccionado.Currently, small wind turbines which don`t generally have an evaluation of their environmental impact are produced and commercialized in Argentina. In this paper, the impact of producing an 1,3 kW wind turbine is studied using a life cycle analysis (LCA). An inventory of all the materials and processes consumed in the manufacturing stage was carried out, followed by the development and analysis of its life cycle. As conclusions, it can be pointed out that the greater contribution to the impact lies in the tower and the generator. This impact damages mostly human health, then natural resources and least of all ecosystem quality.Tema 6: Energía eólica, geotermia, biomasa y otras energías no convencionales.Facultad de Arquitectura y Urbanism

Management of Renal Cell Carcinoma: Evaluation of Renal Masses by Modem Radiological Techniques

The utilty of ultrasound and computed tomography is compared to angiography and that of nephrotomography in the study of renal masses. Ultrasound and computed tomography, noninvasive methods, are replacing nephrotomography and, in some cases, angiograph

Neurosonology: An Update

Recent technological advances in diagnostic ultrasound have resulted in the development of high-resolution, portable real-time scanners. In neurological ultrasound, these devices have been particularly useful for detecting intracranial hemorrhage in premature infants. Sonography is now being used during neurosurgical procedures to help in localizing masses for resection and biopsy, as well as in the placement of shunt catheters. The applications of neurosonology and our experience with intraoperative neurosonology are reported in this review

E-cadherin expression is associated with somatostatin analogue response in acromegaly

Acromegaly is a rare disease resulting from hypersecretion of growth hormone (GH) and insulin‐like growth factor 1 (IGF1) typically caused by pituitary adenomas, which is associated with increased mortality and morbidity. Somatostatin analogues (SSAs) represent the primary medical therapy for acromegaly and are currently used as first‐line treatment or as second‐line therapy after unsuccessful pituitary surgery. However, a considerable proportion of patients do not adequately respond to SSAs treatment, and therefore, there is an urgent need to identify biomarkers predictors of response to SSAs. The aim of this study was to examine E‐cadherin expression by immunohistochemistry in fifty‐five GH‐producing pituitary tumours and determine the potential association with response to SSAs as well as other clinical and histopathological features. Acromegaly patients with tumours expressing low E‐cadherin levels exhibit a worse response to SSAs. E‐cadherin levels are associated with GH‐producing tumour histological subtypes. Our results indicate that the immunohistochemical detection of E‐cadherin might be useful in categorizing acromegaly patients based on the response to SSAs.ISCIII‐Subdirección General de Evaluación y Fomento de la Investigación PI13/02043 PI16/00175FEDER PI13/02043 PI16/00175Junta de Andalucía A‐0023‐2015 A‐0003‐2016 CTS‐1406 BIO‐0139Andalusian Ministry of Health C‐0015‐2014CIBERobn PI13/ 02043 PI16/0017
