The role of reactive astrocitose in the chronological evolution of traumatic brain injury

Introduction and objectives. This study aims to investigate whether the cerebral modifications of posttraumatic reactive astrocitose can be considered an objective criterion for determining the age of traumatic cranio-cerebral lesions. Materials and methods. The present study consists of a series of 23 medico-legal cases that underwent autopsy inTeleormanCounty(Romania) Department of Forensic Medicine during 2007–2016, with full immune-histochemical microscopic examination using GFAP staining. The study consists of two groups, a series of 13 cases with cranio-cerebral trauma with different posttraumatic survival periods and 9 cases as a control group. Results and discussions. We discovered GFAP+ reactive astrocytes even when death occurred immediately after the trauma event and up to 4 months after the traumatic incident. We also discovered an intense positive correlation between the density of the GFAP+ cell from the perilesional area and the posttraumatic survival period. The highest cerebral density of the GFAP+ astrocytes occurred with acute death prior (1 to 24 hours) and the lowest in the chronic period (over 2 weeks). Conclusions. The gradual and differentiated appearance of the reactive astrocytes in close relation with the cerebral posttraumatic interval, with specific lesional and perilesional distribution as well as in surrounding area, clearly demonstrates that the state of the reactive astrocitose may constitute an objective index for evaluation of the elapsed time after the posttraumatic event

Quality utility modelling for multimedia applications for Android mobile devices

With the advances in mobile technologies, smart mobile computing devices have become increasingly affordable and powerful, leading to a significant growth in both the number of advanced mobile users and their bandwidth demands. Moreover multimedia streaming to these high-end mobile devices has become widespread. However, multimedia applications are known to be resource-hungry and in order to cope with this explosion of data traffic, operators have started deploying different, overlapping radio access network technologies. One important challenge in such a heterogeneous wireless environment is to ensure an Always Best Experience to the mobile user, anywhere and anytime. This paper proposes the Quality Utility, a realistic mapping function of the received bandwidth to user satisfaction for multimedia streaming applications. The Quality Utility is mapped to a Google Nexus One Android Mobile device and validated through objective and subjective tests

Arguments as abstract objects

In recent discussions concerning the definition of argument, it has been maintained that the word ‘argument’ exhibits the process-product ambiguity, or (as in Goddu forthcoming) an act/object ambi-guity. Drawing on literature on lexical ambiguity we argue that ‘argument’ is not ambiguous. The term ‘argument’ refers to an object, not to a speech act. We also examine some of the important implications of our argument by considering the question: what sort of abstract objects are arguments

„AIR AND WATER – COMPONENTS OF THE ENVIRONMENT” CONFERENCE AT 10 YEARS OF EXISTENCE

The Faculty of Geography has experienced a constant and accelerated development since 1994, when it became an independent subunit of Babeş-Bolyai University. In this context, in 2006, the fifth and the newest specialization of the faculty, Hydrology and Meteorology, was launched as Bachelor studies level. This specialization has as main aim to meet to practical needs, namely the training of specialists for several fields of the economic development, mainly for the national hydrological and meteorological networks. In order to provide a superior level of education for this specialization, in 2009 was established the Master studies program, under the title Resources and risks in the hydro-atmospheric environment. This ensured the complex training of future hydrologists and meteorologists. Over the 10-years period, the two study programs have been quite attractive, the number of students in the 1st year oscillating between 20 and 30 students, at Bachelor level and between 10 and 20 students, at Master level (Pandi, 2014). The opportunity and success of the specializations resulted also from the relatively high number of graduates who have been employed in the hydrological and meteorological national networks, as well as in other institutions. Moreover, many employees from the branches of the „Romanian Waters” National Administration and the National Meteorological Administration have completed their studies at a bachelor or master level. Most graduates work as hydrologists or meteorologists in weather and hydrological stations, research institutes, water basin monitoring offices, water management departments including leadership positions etc
