Materijalni i procesni uslovi za zasnivanje odnosa roditelja i deteta u savremenom porodičnom pravu
The subject of this paper are, primarily, the methods of
determining and disputing maternity and paternity, regulated by the
Family law on the Republic of Serbia. In order to shed light on them
in a comprehensive way, we will divide the work into four logical
units, ie. four chapters. In the first chapter, we will present general
concepts about the parent-child relationship, its basic manifestations
and legal phenomena that are directly related to it. In the next chapter,
we will deal with the material and procedural aspects of the child's
family status, trying to clarify its characteristics in the domestic and
the rights of individual European countries (France, Germany,
Austria, Montenegro, Croatia, Russia). Therefore, we will research
the methods for determining maternity in domestic and comparative
law, pointing out that in some countries it can be based on
recognition, and not only on the entry of data on the mother in the
birth register and, possibly, on the verdict. In the sphere of paternity
rules, we will distinguish between marital and extramarital paternity,
so we will underline the different conditions that must be met in
certain countries in order for the (ex)husband of the mother to be
considered the father of the child. We will also present the different
conditions for challenging marital paternity and the practice of the
ECHR on this issue. In the domain of extramarital paternity, we will
compare domestic and foreign rules on the conditions for his
recognition and on the possibilities of oppugning him. In the
procedural part of the paper, we will pay special attention to actively
legitimized persons for initiating litigation to determine and challenge
maternity and paternity, and to the deadlines prescribed in domestic
and analyzed foreign laws.
The third chapter will be dedicated to the issue of
establishing parenthood with biomedical assistance, and in it we will
present the general rules on these procedures in domestic and
comparative law, the types of these procedures and their disputable
elements. We will pay special attention to surrogacy, from the point
of view of existing proposals in domestic law and positive solutions
from comparative law. Given the importance of this institution, in this
part of the research we will deal with the rights of those countries that
we have not studied in the course of work so far, and in which
surrogacy is allowed, such as Greece, Canada, Ukraine, Macedonia,
Great Britain and the USA. We will deal with the conditions under
which it is allowed, its types (commercial and non-commercial,
complete and incomplete subrogation, posthumous insemination of a
surrogate mother), ways and conditions of using the services of a
surrogate mother, contractual rights and obligations of intended
parents and surrogate mother, status of the child surrogate mother. We
will also analyze the characteristic decisions of the ECHR concerning
surrogacy, which may be a kind of roadmap for the Serbian legislator.
In the last chapter, researching the rules on adoption, we
will deal with its concept, historical development, functions, material
and formal conditions for its establishment, types, effect and methods
and consequences of its termination. As the Preliminary draft
proposes a return to incomplete adoption, which was not so long ago
present in Serbian family law, we will also express our opinion on it.
Considering that the biggest differences between domestic and certain
foreign laws are manifested in the sphere of the age difference
between adopters and adoptees, we will deal with it in particular, in
order to draw a conclusion about the one that best suits natural laws
and modern needs. We will point out the importance of the best
interest of the child as a condition for establishing adoption, both in
domestic and comparative law, and in the practice of the ECHR
The role of humoral immune response in the aetiopathogenesis of amyotrophic lateral sclerosis
Amiotrofična lateralna skleroza (ALS) je fatalna neurodegenerativna bolest sa
početkom u adultnom dobu koja se karakteriše progresivnim gubitkom gornjih i donjih
motoneurona, što dovodi do atrofije muskulature, mišićne paralize i smrti usled slabosti
respiratorne muskulature. Oko 5-10% ALS slučajeva su sa familijarnom istorijom bolesti
(fALS), dok su preostali slučajevi sporadični (sALS) sa nepoznatim uzrokom bolesti. Cilj
ove disertacije bio je da proceni efekat imunoglobulina G (IgG) izolovanog iz sALS
bolesnika (ALS IgG) na homeostazu kalcijuma i mobilnost endozoma/lizozoma kod
pacovskih kortikalnih astrocita u kulturi. ALS IgG (0.1 mg/ml) poreklom od 7 ALS
pacijenata, za razliku od IgG iz 3 kontrolne osobe, izazvao je prolazne promene
unutarćelijske koncentracije kalcijuma (Ca2+-talas) u astrocitima. Povećana aktivnost
kalcijuma detektovana je kod oko polovine astrocita nakon tretmana sa ALS IgG, bez
obzira na prisustvo vanćelijskog kalcijuma (47,5 ± 12,9 %, 2 mM Ca2+ naspram 48,2 ± 13,6
%, 0 mM Ca2+). U prisustvu vanćelijskog kalcijuma, maksimalna vrednost promene
dostignuta je ~3x brže (19,7 ± 2,8 s, 2 mM Ca2+ naspram 56,3 ± 6,8 s, 0 mM Ca2+) i ukupno
povećanje kalcijuma (površina pod Ca2+-talasom) bilo je ~1.7x veće (26,0 ± 1,6 F/F0 *s, 2
mM Ca2+ naspram 15,6 ± 1.1 F/F0 *s, 0 mM Ca2+), ali vanćelijski kalcijum nije uticao na
maksimum amplitude kalcijumovog talasa. Primena farmakoloških inhibitora otkrila je da
je aktivacija inozotol 1,4,5-trifosfatnog (IP3), za razliku od rianodinskog receptora
neophodna i dovoljna da inicira povećanu aktivnost, a ulazak kalcijuma kroz TRPC kanale
produžava odgovor. Inhibicija fosfolipaze C (PLC) umanjuje, dok inhibicija
fosfatidilinozitol-3-kinaze (PI3K) u potpunosti sprečava tipičan ALS IgG-izazvan
kalcijumski odgovor. Populacija vezikula obeleženih lizotrekerom koji boji endozome i
lizozome, sastojala se od stacionarnih vezikula (6,1%) sa prosečnom brzinom koja nije
prelazila 67 nm/s i mobilnih vezikula (93.9%) čija je ukupna dužina putanje (TL) pređene
za 15 s iznosila u proseku 3,03±0,01 μm. ALS IgG (0.1 mg/ml) poreklom iz 12 od 13 ALS
bolesnika povećao je TL mobilnih vezikula za ~24% i maksimalni pomeraj (MD) za ~26%
tokom praćenih 4 min, za razliku od kontrolnih IgG (poreklom od 4 osobe) koji nisu uticali
na mobilnost vezikula. ALS IgG-izazvano povećanje mobilnosti bilo je manje izraženo u
rastvoru bez Ca2+, što ukazuje da su promene u homeostazi kalcijuma uključene u proces
kojim ALS IgG povećava mobilnost vezikula. Interesantno, ALS IgG kao i ATP (1 mM)
nisu uticali na oslobađanje sadržaja vezikula, što znači da je brza i kompletna egzocitoza
malo verovatan događaj kod astrocita u kulturi u našim eksperimentalnim uslovima.
Sumarno, ALS IgG utiče na kalcijumovu homeostazu astrocita preko IP3-posredovanog
oslobađanja kalcijuma iz endoplazmatičnog retikuluma i ulaska kalcijuma kroz TRPC
kanale, uz aktivaciju PI3K uzvodno od PLC. ALS IgG povećavaju mobilnost endozoma i
lizozoma, a ovaj efekat delimično zavisi od vanćelijskog kalcijuma. Ova studija je otkrila
molekulske mehanizme kojima astrociti postaju meta humoralnog imunskog odgovora u
ALS, što može da doprinese etiopatogenezi bolesti.Amyotrophic lateral sclerosis (ALS) is an adult onset fatal neurodegenerative
disease characterized mainly by the progressive loss of upper and lower motor neurons
resulting in wasting, paresis and death from respiratory failure. Approximately 5-10% of
ALS cases are familial (fALS), while the rest are sporadic (sALS) with unknown cause of
disease. The objective of this dissertation was to evaluate the effect of immunoglobulin G
(IgG) isolated from sALS patients (ALS IgG) on calcium homeostasis and mobility of
endosomes/lysosomes in cultured rat cortical astrocytes. ALS IgG (0.1 mg/ml) from 7 ALS
patients, but not IgG from 3 control individuals evoked calcium transients (Ca2+-waves) in
astrocytes. About half of the tested astrocytes responded with elevated calcium activity
regardless of the presence of extracellular calcium (47.5 ± 12.9 %, 2 mM Ca2+ vs. 48.2 ±
13.6 %, 0 mM Ca2+). In presence of extracellular calcium, the peak amplitude developed
~3x faster (19.7 ± 2.8 s, 2 mM Ca2+ vs. 56.3 ± 6.8 s, 0 mM Ca2+) and the overall magnitude
of calcium rise (area under the Ca2+-wave) was ~1.7x larger (26.0 ± 1.6 F/F0 *s, 2 mM Ca2+
vs. 15.6 ± 1.1 F/F0 *s, 0 mM Ca2+), while the peak amplitude itself was not affected.
Application of pharmacological inhibitors revealed that activation of inositol 1,4,5-
triphosphate (IP3), but not of ryanodine receptors is necessary and sufficient to initiate
elevated activity, while the influx of extracellular calcium through TRPC channels prolongs
the responses. Inhibition of phospholipase C (PLC) diminishes, while the inhibition of
phosphatidilinositol-3-kinase (PI3K) completely prevents typical ALS IgG evoked calcium
response. The population of vesicles labeled with lysotracker that mainly stains endosomes
and lysosomes, consisted of non-mobile (6.1%) vesicles with the average speed of <67
nm/s and mobile vesicles (93.9%) with total track length (TL) in 15 s averaging at
3.03±0.01 μm. ALS IgG (0.1 mg/ml) from 12 of 13 patients increased the TL of mobile
vesicles by ~24% and the maximal displacement (MD) by ~26% within 4 min, while IgG
from control group (n=4) did not alter the vesicle mobility. The mobility enhancement by
ALS IgG was less pronounced in Ca2+-free extracellular solution, indicating that ALS IgG
vesicle mobility enhancement involves changes in Ca2+ homeostasis. Interestingly, neither
ALS IgG nor ATP (1 mM) triggered the release of vesicular cargo, making rapid and
complete exocytosis unlikely in cultured astrocytes in our experimental conditions. In
conclusion, ALS IgG affect calcium homeostatic system in astrocytes by IP3 mediated
calcium release from the endoplasmic reticulum and entry of extracellular calcium through
TRPC channels, with the activation of PI3K upstream of PLC. ALS IgG enhance the
mobility of endosomes and lysosomes, and this effect is partialy dependent on extracellular
calcium. This study revealed the molecular mechanisms by which astrocytes become
targeted cells for humoral immune response in ALS that could contribute to the
aetiopathogenesis of the disease

MLP ANN Condition Assessment Model of the Turbogenerator Shaft A6 HPP Đerdap 2
This paper describes a model for estimating the condition of the shafts of turbines of the current generator in Hydropower plant Đerdap 2. For this purpose, an integral diagnostic approach was used. Based on the diagnostics of the condition of the shaft and the estimated lifetime, a multi-layer perceptron (MLP) based artificial neural network (ANN) is built, which is able to estimate the remaining lifespan of the turbine shaft. The MLP ANN model has not been made in this way on turbogenerators of hydroelectric power plant Đerdap 2 until now. The significance of this approach is that experiment brings about topology of ML ANN (number of neurons and layers) which is optimal for this model, training and testing. Results obtained from the neural network can be further used for decision-making about the moment of diagnosis or maintenance actions, as well as reducing stagnation and production losses
Upcycling of the Used Cigarette Butt Filters through Pyrolysis Process: Detailed Kinetic Mechanism with Bio-Char Characterization
Thermo-chemical conversion via the pyrolysis of cigarette butt (CB) filters was successfully valorized and upcycled in the pre-carbonization and carbonization stages. The pre-carbonization stage (devolatilization) of the precursor material (cellulose acetate filter, r-CAcF) was analyzed by micro-scale experiments under non-isothermal conditions using TG-DTG-DTA and DSC techniques. The results of a detailed kinetic study showed that the decomposition of r-CAcF takes place via complex mechanisms, including consecutive reaction steps and two single-step reactions. Consecutive stages include the α-transition referred to as a cellulose polymorphic transformation (cellulose I → II) through crystallization mechanism changes, where a more thermodynamically ordered system was obtained. It was found that the transformation rate of cellulose I → II (‘cellulose regeneration’) is strongly affected by the presence of alkali metals and the deacetylation process. Two single-step reactions showed significant overlapping behavior, which involves a nucleation-controlled scission mechanism (producing levoglucosan, gaseous products, and abundant radicals) and hydrolytic decomposition of cellulose by catalytic cleavage of glycosidic bonds with the presence of an acidic catalyst. A macro-scale experiment showed that the operating temperature and heating rate had the most notable effects on the total surface area of the manufactured carbon. A substantial degree of mesoporosity with a median pore radius of 3.1695 nm was identified. The presence of macroporosity on the carbon surface and acidic surface functional groups was observed
Risk education in Serbia
Natural disaster risk reduction can be achieved through vulnerability reduction, as well as through strengthening the resilience of the population. One of the segments leading to these aims is a proper risk education. It is the public (compulsory) education system that reaches the greatest number of participants and represents a good platform for the natural disaster knowledge transfer. Geography, as a complex subject that includes both natural and social components, is the most appropriate to transfer the knowledge necessary to improve the resilience. Research done in Serbia (detailed analyses of curricula, textbooks, teachers' role and pupils' knowledge) shows that children do learn about natural disasters but not in a way which provides usable knowledge
An Overview of S-Genotype Diversity in Sweet Cherry Landraces Grown in the Central Region of the Republic of Serbia
Identification of the S-genotypes in landraces is a crucial step in the molecular characteri- zation of Serbian autochthonous sweet cherry germplasm. It is also of enormous significance for bre- eders and growers, as this fruit species exhibits a gametophytic self-incompatibility, controlled by the multi-allelic two genes of the S-locus. The aim of this study was to summarize known information and reveal new data on the S-alleles in 23 sweet cherry landraces originating in the Republic of Ser- bia. The use of polymerase chain reaction (PCR) with consensus primers for the second intron of S- RNase, primers specific for S-RNase and certain SFB alleles, along with DNA fragment analysis using fluorescently labelled forward primers to amplify both the S-RNase first intron and the SFB in- tron, revealed 10 alleles (S1 to S6, S9, S12, S13 and S22) that generated the following 13 S-genotypes: S1S2 (one landrace), S1S4 (one landrace), S1S5 (one landrace), S2S3 (four landraces), S3S4 (two lan- draces), S3S5 (two landraces), S3S6 (three landraces), S3S9 (two landraces), S3S12 (two landraces), S4S5 (one landrace), S4S13 (one landrace), S5S22 (one landrace) and S6S9 (two landraces). The most frequent S-allele and S-genotype in this sweet cherry material were S3 and S2S3, with occurrence fre- quencies of 32.6% and 17.4%, respectively. Based on the obtained results, the sweet cherry landraces were assigned to 12 incompatibility groups and one group of universal donors (‘0’). These results pro- vide important information about their cross-compatibility and the diversity of the S-locus in Serbian sweet cherry germplasm
