Based upon findings and results from our recent research (De Vocht et al., 2011) we propose a generic framework concept for researcher profiling with appliance to the areas of ”Science 2.0” and ”Research 2.0”. Intensive growth of users in social networks, such as Twitter generated a vast amount of information. It has been shown in many previous works that social networks users produce valuable content for profiling and recommendations (Reinhardt et al., 2009; Java et al., 2007; De Vocht et al., 2011). Our research focuses on identifying and locating experts for specific research area or topic. In our approach we apply semantic technologies like (RDFb, SPARQLc), common vocabularies (SIOCd, FOAFe, MOATf, Tag Ontologyg) and Linked Datah (GeoNamesi, COLINDAj) (Berners-Lee, 2006; Bizer et al., 2012) .
The aim of this study was to determine whether volume and localization of intracerebral hematoma affects the six-month prognosis of patients with intracerebral hemorrhage (ICH). Patients and Methods. The study included 75 patients with ICH of both sex and all age groups. ICH, based on CT scan findings, was divided in the following groups: lobar, subcortical, infratentorial, intraventricular haemorrhage and multiple hematomas. Volume of intracerebral hematoma was calculated according to formula V = 0.5 × a × b × c. Intracerebral hematomas, according to the volume, are divided in three groups (0–29 mL, 30–60 mL, and >60 mL). Results. The highest mortality rate was recorded in the group with multiple hematomas (41%), while the lowest in infratentorial (12.8%). The best six-month survival was in patients with a volume up to 29 mL, 30 of them (64%) survived. The highest mortality rate was recorded in patients with the hematoma volume >60 mL (85%). Kaplan-Meier's analysis showed that there was statistical significance between the size of the hematoma and the six-month survival (P < 0.0001). More than half of patients (61.1%) who survived 6 months after ICH were functionally independent (Rankin scale ≤2). Conclusion The volume of hematoma significantly affects six-month prognosis in patients with intracerebral hemorrhage, while localization does not.
U teorijskoj organskoj hemiji, zakoni molekulsko – orbitalne teorije omogucuju da se odrede energetska stanja π – elektrona u konjugovanim (nezasicenim) jedinjenjima. Pri ovome energetski nivoi elektrona, dobijaju se razvijanjem odgovarajuce determinante koja se formira koristeci tri karakteristicne matrice po definiciji. Svakom jedinjenju, pri ovome pridružuje se odgovarajuci polinom, dok ce energetski nivoi zavisiti od njegovih nula. Kod velike vecine jedinjenja koja se susrecu u teoriji i praksi, dobijeni polinom uvek ima bar jednu racionalnu nulu pa se problem resava jednostavno metodom faktorizacije. Problem nastaje kada karakteristicni polinom nema ni jednu racionalnu nulu. U ovom slucaju moguca je primena gotovih matematickih formula koje su međutim nepodesne za prakticnu upotrebu. Isto tako moguca je i primena numerickih metoda, koje daju samo približno realno resenje koje nije pogodno za primenu s obzirom da se gotovo uvek traži tacno realno resenje. Uzimajuci u obzir predhodno, u radu bice dat predlog za resavanje gore navedenog problema na bazi formiranja ekvivalentnih jednacina preko odgovarajucih matematickih transformacija, koje omogucuju da se na relativno jednostavan nacin dobiju tacno sve realne nule polinoma. U prikazanom radu, resavanje matematickog problema bice ilustrovano na nekoliko karakteristicnih primera. Tacnost dobijenih rezultata prema predloženoj metodi bice izvedena poređenjem sa približnim numerickim resenjem koristeci odgovarajuci racunarski program, odnosno numericke metode.
