Apariţia de noi tipuri de detectori cu scintilatori anorganici LaBr3(Ce) şi LaCl3(Ce), a generat necesitatea testării lor pentru diferite aplicaţii. Ca o alternativă a detectorului NaI(Tl), utilizat, în mod tradiţional, în sistemele gama de monitorizare a I-131, în tiroidă, a fost considerat pentru caracterizare, un detector LaBr3(Ce), de dimensiuni 1.5“ x 1.5”. Rezultatele au fost evaluate, ur...

Coumarins are classified as a member of the benzopyrone family. all of which consist of a benzene ring joined to a pyrone ring. The benzopyrones can be subdivided into the benzoalfa-pyrones to which the coumarins belong and the benzo-gama-pyrones, of which the flavonoids are principal members. Umbelliferone, esculetin and scopoletin are the most widespread coumarins in nature. During the synthe...

Agent-based models are now used in numerous application domains (ecology, social sciences, etc.) but their use is still impeded by the lack of generic yet ready-to-use tools supporting the design and the simulation of complex models integrating multiple level of agency and realistic environments. The GAMA modeling and simulation platform is proposed to address such issues. It allows modelers to...

Dr. Rômulo L. Gama – Rede Sarah de Hospitais de Reabilitação Avenida Presidente Juscelino Kubitscheck 4500 60861-630 Fortaleza CE Brasil. E-mail: [email protected] Developmental venous anomaly (DVA), also known as venous angioma, is becoming the most commonly encountered intracranial vascular malformation in central nervous system (CNS) imaging. It is thought that DVA develops during developm...

Agent-based modeling is used to study many kind of complex systems in different fields such as biology, ecology, or sociology. Visualization of the execution of a such complex systems is crucial in the capacity to apprehend its dynamics. The ever increasing complexification of requirements asked by the modeller has highlighted the need for more powerful tools than the existing ones to represent...

ZnO and ZnO:Mn nanocrystals synthesized via reverse micelle method. The size, band gap, Urbach energy, optical constants and penetration depth of nanocrystals were calculated by UV-vis spectroscopy data. The surface morphology was studied with the use of scanning electron microscope (SEM). Moreover the samples exposed to Gama ray source of 60Co and their thermoluminescence properties...

Objective: To investigate whether 14-3-3 eta protein is detectable in synovial fluid and blood serum of high performance horses and to study whether any significant correlation between this and matrix metalloproteinase 1 and 3 in horse synovial fluid. Design: Clinical study. Animals: Eleven standard breed horses (seven high performances and four controls). Procedures: Blood serum and fetlock...
