La trazabilidad en la Ingeniería de Software es una práctica de control que ayuda a obtener el producto en el dominio de la solución lo más exacto y fiable posible a las necesidades expresadas por el cliente. En el desarrollo de aplicaciones web, los requerimientos poseen características particulares, las cuales no están contempladas explícitamente en los estándares vigentes. En esta línea de trabajo se analizan los aspectos vinculados a la especificación de requerimientos y la explicitación de mecanismos de trazabilidad en el desarrollo de aplicaciones web, basadas en criterios de calidad definidos por los estándares vigentes. El objetivo principal es generar metodologías y herramientas de software que contribuyan al desarrollo de software para la web, cumpliendo requisitos de calidad.

Introduction. Acute renal failure is a common complication in critically ill newborn infants. The therapy of acute renal failure is conservative and etiological. Patients not responding to this kind of therapy require peritoneal dialysis. Material and methods. This retrospective study included 6 newborn infants undergoing peritoneal dialysis during the period from January 2004 to June 2006, at the Nephrology Department of the Institute of Child and Youth Health Care in Novi Sad. All patients presented with complications of acute renal failure including hypercalemia and uremic encephalopathy. Results. Complete restoration of kidney function was evident in four patients on peritoneal dialysis. Three patients are still alive, but in one patient acute renal failure progressed to chronic renal failure. One patient died in the third month of life due to multiple organ dysfunction, after just two days of dialysis. Several complications were reported: intra-abdominal hemorrhage, dialysate l...

In this paper, we introduce the pyramidal robot, a novel kind of parallel cable-based robot that has been constructed and designed with five cables. Last, we suggested a control method. In this context, we studied the application of the Runge-Kutta method of fourth order for resolving the non-linear partial differential equations of our system, which is frequently employed for managing uncertainties in linear systems. The primary contribution of this study is firstly the design of a reel prototype and the creation and implementation of a graphical user interface (GUI) for displaying the position of the end effector. Second, to test the precision of the tracking of the object, we analyse the system’s response using cutting-edge methods such as predictive control. Finally, using the advanced technique proposed, we present the simulation results on this cable-based robot. These results demonstrate the performance of the technique as proposed.

Pediatric obesity has a growing health and socio-economical impact due to cardiovascular and metabolic complications in adult life. Some recent studies suggest that live or heat-treated probiotics have beneficial effects in preventing fat deposition and obesity in preclinical and clinical sets. Here, we have explored the effects of heat-treated probiotic Bifidobacterium animalis subsp. lactis CECT 8145 (HT-BPL1), added as a supplement on an infant milk formula (HT-BPL1-IN), on Caenorhabditis elegans fat deposition and short-chain fatty acids (SCFAs) and lactate, using fermented baby fecal slurries. We have found that HT-BPL1-IN significantly reduced fat deposition in C. elegans, at the time it drastically augmented the generation of some SCFAs, particulary acetate and organic acid lactate. Data suggest that heat-treated BPL1 maintains its functional activities when added to an infant powder milk formula.

Spain from the historical point of view remains, without a doubt, one of the key sceneries in medieval Europe where the East and the West intersected in a fruitful way. The prominence of the Jewish people in this process played an unquestionable part in it. In this context the anti-Semitic component in the construction of Galician nationalism is interesting, while creating the founding myth contrasts the West and the East. In the background of this great cultural creation, full of consequences, we may glimpse the absent history of Galicia, the small demos of the western end of the Roman Finisterrae.
