QUALINET white paper on definitions of Immersive Media Experience (IMEx)
With the coming of age of virtual/augmented reality and interactive media,
numerous definitions, frameworks, and models of immersion have emerged across
different fields ranging from computer graphics to literary works. Immersion is
oftentimes used interchangeably with presence as both concepts are closely
related. However, there are noticeable interdisciplinary differences regarding
definitions, scope, and constituents that are required to be addressed so that
a coherent understanding of the concepts can be achieved. Such consensus is
vital for paving the directionality of the future of immersive media
experiences (IMEx) and all related matters.
The aim of this white paper is to provide a survey of definitions of
immersion and presence which leads to a definition of immersive media
experience (IMEx). The Quality of Experience (QoE) for immersive media is
described by establishing a relationship between the concepts of QoE and IMEx
followed by application areas of immersive media experience. Influencing
factors on immersive media experience are elaborated as well as the assessment
of immersive media experience. Finally, standardization activities related to
IMEx are highlighted and the white paper is concluded with an outlook related
to future developments
Evaluation of dormance sunflower seed lots
U Laboratoriji za ispitivaje semena Instituta za kukuruz Zemun Polje,
u toku redovnog ispitivanja klijavosti semena suncokreta, uoÄeno je
kod dve partije semena veliki broj neklijalog semena. Seme je
stavljeno na naklijavanje dva puta sa razliÄitim temperaturnim
reĆŸimom. U toku prvog ispitivanja seme je stavljeno na klijanje
metodom izmeÄu filter papira, hlaÄenje semena je trajalo 6 dana,
energija klijanja je oÄitana Äetvrtog dana a ukupna klijavost desetog
dana. Seme je naklijavano u klijaliĆĄtu na 200C sa reĆŸmom svetlosti 8
sati dan, 16 sati noÄ. U toku drugog ispitivanja, seme suncokreta je
postavljeno na klijanje istom metodom izmeÄu filter papira, hlaÄeno
je 6 dana, energija klijanja je oÄitana Äetvrti dan a zavrĆĄna klijavost
deseti dan. Naklijavanje je obavljeno u sobi klijaliĆĄtu na naizmeniÄnoj
temperaturi 20300C, sa svetlosnim reĆŸimom 8 sati dan, 16 sati
noÄ. UraÄen je i TTZ - tetrazolium test. Analizom dobijenih rezultata
uoÄeno je da na kraju prvog ispitivanja izdvojen veliki broj neklijalog
semena koje je bilo sveĆŸe bez simptoma bolesti. Na kraju drugog
ispitivanja taj procenat je bio manji u odnosu na prvo ispitivanje.
Naklijavanje semena na veÄoj, naizmeniÄnoj temperaturi 20300C,
u toku drugog ispitivanja, smanjilo je broj neklijalog semena. TTZ
testom je potvrÄena vitalnost neklijalog semena.A great number of nongerminated sunflower seed of two lots were
observed during regular testing in the Seed Testing Laboratory of the
Maize Research Institute, Zemun Polje. Seeds were germinated
twice under different temperature regimes. In the course of the first
test, seeds were germinated between filter paper, cooling lasted 6
days, the first count was done on the fourth day, while total
germination was determined on the 10th day. Seeds were germinated
in the germination cabinet at 200oC with 8 h (light) to16 h (night)
regime. In the course of the second test, the method applied was the
same: sunflower seeds were germinated between filter paper,
cooling lasted 6 days, the first count was done on the fourth day,
while total germination was determined on the 10th day. Germination
was performed in the germination cabinet at the alternating
temperature of 20300oC, and the light regime of 8 h (light) to16 h
(night). The TTZ -tetrazolium test was also performed. The analysis
of obtained results showed that a great number of nongermination,
but fresh and disease-free seeds were detected at the end of the first
test. The corresponding percentage at the end of the second test
was smaller. Seed germination at higher, alternating temperatures of
20300oC, in the course of the second test, reduced the number of
nongerminated seeds. Seed viability was confirmed by the TTZ test
A contribution to pharmaceutical biology of freshwater sponges
<p><i>In vitro</i> anti-tumour and anti-radical activities of the acetone extract of the freshwater sponge <i>Ochridaspongia rotunda</i> were the subject of this study. The extract was found to be highly cytotoxic to human lung tumour cell line A-549 reaching IC<sub>50</sub> value of 5.01 ± 0.21 Όg/mL. Indeed, it displayed only 2-fold less anti-tumour activity than doxorubicin (IC<sub>50</sub> value 2.42 ± 0.13 Όg/mL) used as a positive control. The same extract was also found to be almost 37-fold more selective against A-549 vs. MRC-5 (normal) lung cells, in difference to weak selectivity of doxorubicin (less than 3-fold). Its profound anti-DPPH radical activity comparable to that of quercetin (IC<sub>50</sub> values 3.68 ± 0.19 and 3.14 ± 0.09 Όg/mL, respectively) coupled with no signs of genotoxicity in the comet assay (MRC-5 cell line, vs. doxorubicin) has actually implicated the importance of this animal bioresource in searching for pharmaceutically useful bioactive compounds of natural origin.</p

<p>The effect of subinhibitory concentrations (1/2â1/256 X MIC) of lichenocin 50.2 (2a) and BGBU1-4 crude extract (2b) on biofilm formation of <i>L</i>. <i>monocytogenes</i>. Results are presented as mean OD ± standard deviation; Category +, weak biofilm producer; Category ++, moderate biofilm producer; Category +++, strong biofilm producer; * p<0.05, ** p<0.01.

With the coming of age of virtual/augmented reality and interactive media,
