Kulturna geografija trgovačkih centara; primjer Arena Centra Zagreb kao nemjesta s elementima mjesta i javnog prostora

Cilj je ovog rada kroz kulturnu geografiju pružiti novi pogled na pojmovne odrednice mjesta, prostora, spomen-mjesta, nemjesta i javnih prostora, koje se u današnjem globalizacijskom i tranzicijskom društvu sve više preklapaju, otežavajući tako jasnu klasifikaciju. Trgovački centar, jednom tipičan primjer Augeovog nemjesta, s popularizacijom kapitalizma i konzumerizma ulazi u sferu javnih događanja i iskorištavanja slobodnog vremena, čime stječe dodatne odrednice pogodne za analizu i istraživanje. Na primjeru Arene Centar Zagreb istražit će se i predstaviti odrednice suvremenih trgovačkih centara, u odnosu na one javnog prostora, mjesta i nemjesta.This paper uses cultural geography to provide a new insight into characteristics of place, space, non-place, public spaces and memorials, which are becoming increasingly difficult to define as they begin to overlap in today’s globalized transitional society. Once an epitome of Auge's non-place, the malls are increasingly becoming venues of public events and leisure. The original classification of the malls as in hence brought into question, as they gain new uses and characteristics that require further research. The characteristics of malls and their relation the determinants of places, non places and public spaces is explored here on the example of Arena Centar Zagreb

Spatial cognition of the Mediterranean in Croatia

Iako se Sredozemlje smatra jednom od najstarijih prostornih cjelina u svijetu, njegove su granice još uvijek predmet istraživanja i rasprava. Ovaj rad nastoji pridonijeti definiranju Sredozemlja ili Mediterana kroz ispitivanje percepcije njegova prostornog obuhvata u Hrvatskoj i povezanosti s fizičkim i sociokulturnim obilježjima prostora. Istraživanje je provedeno metodom kognitivnih karata na uzorku od dvjesto ispitanika. Kao rezultat dobivena je široka granična zona koja razdvaja tzv. \u27\u27pravo\u27\u27 Sredozemlje od područja koja nisu dijelovi Sredozemlja. Ta zona u određenoj mjeri ima svojstva neizrazitog skupa (engl. fuzzy set) koji predstavlja postupni prijelaz između polova pripadnosti određenom skupu. Rezultati istraživanja na ispitanicima pokazali su da je najveća podudarnost percipiranih granica Sredozemlja s dinarskim smjerom pružanja reljefa (sjeverozapad-jugoistok), osim u Istri, te s obalnom crtom u čitavom hrvatskom primorju. Rezultati također pokazuju da su pri odabiru percipirane granice Sredozemlja čimbenici prirodne sredine važniji od sociokulturnih.Although the Mediterranean is considered to be one of the oldest regions in the world, its borders are still the subject of discussion and research. This paper aims to contribute to the definition of the Mediterranean by studying the perception of its spatial coverage in Croatia and its links to the physical and socio-cultural attributes of space. The research was conducted by using the cognitive map method on the sample of 200 participants. The result was a broad border zone separating the so-called "real" Mediterranean from areas which are not part of the Mediterranean. This zone is somewhat similar to a fuzzy set, representing a gradual transition between two ends belonging to a certain set. The research indicates that the congruence of perception of the borders of the Mediterranean is the largest along the Dinaric Alps (northwest – southeast), except in Istria, and the coastal spread along the entire Croatian littoral. The results also indicate that factors relating to the natural environment take precedence over socio-cultural factors in the perception of borders of the Mediterranean

Praćenje srednje moždane arterije transkranijskom dopler sonografijom tijekom stimulacije govora u afatičnih bolesnika

Hemodynamic changes can be noninvasively real-time monitored in stroke patients by means of transcranial Doppler sonography (TCD). The aim of this pilot study was to assess hemodynamic changes in both middle cerebral arteries (MCA) in aphasic stroke patients by means of TCD during verbal stimulation. Eight aphasic patients with stroke in the territory of the left MCA were tested by modified Boston Diagnostic Aphasia Examination (BDAE) within 3 days of stroke onset. Both MCA were monitored simultaneously by means of TCD with 2 MHz probes. Basic MCA mean blood flow velocity (MBFV) values were assessed and monitored during verbal stimulation. Verbal stimulation was performed with 30 photos of objects for daily usage, arranged by function. The same test was performed in 16 right-handed healthy controls. In stroke patients, the mean MBFV were 56 cm/s in the left MCA and 56 cm/s in the right MCA. A mean 30% increase was observed in the left MCA and 22% in the right MCA. In healthy controls, a mean 21.7% increase was observed in the left MCA and 18% in the right MCA. A trend toward higher percentage of MBFV increase was observed in the left MCA during verbal stimulations in aphasic patients as compared to control subjects.Promjene moždane hemodinamike u srednjoj moždanoj arteriji (SMA) u bolesnika s moždanim udarom u irigacijskom području lijeve moždane arterije, te s posljedičnom afazijom mogu se neinvazivno pratiti pomoću funkcionalne transkranijske dopler sonografije (fTCD). Pritom se kao funkcionalni podražaj može koristiti stimulacija govora u obliku logopedskih vježbi. Da bismo procijenili aktivaciju SMA tijekom receptivne i ekspresivne verbalne stimulacije, ispitivanje afazije proveli smo modificiranim bostonskim dijagnostičkim testom u irigacijskom području lijeve SMA kod 8 bolesnika s moždanim udarom unutar 3 dana od nastanka ishemičnog moždanog udara. U obje smo SMA praćenje TCD-om proveli istodobno pomoću 2 ultrazvučne sonde frekvencija 2 MHz. Srednje brzine strujanja krvi (SBSK) u SMA procjenjivali smo i pratili prije i tijekom govorne stimulacije. Stimulaciju govorom proveo je logoped baterijom logopedskih vježbi, te zadacima imenovanja uz pomoć 30 fotografija predmeta svakodnevne uporabe grupiranih prema funkcijama. Isto ispitivanje je provedeno u 16 zdravih dešnjaka. Srednje brzine strujanja krvi bile su: 56 cm/s u lijevoj ACM, te 56 cm/s u desnoj SMA. U lijevoj je SMA tijekom stimulacije govora zabilježen srednji 30%-tni rast SBSK, a u desnoj SMA 22%-tni rast u odnosu na mirovanje. U zdravih kontrolnih osoba u lijevoj je SMA zabilježen porast SBSK od 21,7%, a u desnoj SMA od 18%. Uočen je trend rasta SBSK u lijevoj SMA tijekom stimulacije govora u afatičnih bolesnika u usporedbi sa zdravim kontrolnim osobama

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
