AB  - Aerophytic phototrophs, colonizers of different substrates exposed to air, among which are rock substrates in cave habitats, are in general not sufficiently investigated and studied. From the ecological point of view, seasonal/temporal variations and parameters that influence aerophytic phototrophic communities through seasons still remain largely unknown. Seasonal analysis of phototrophic microorganisms from biofilms developed at entrances of Samar and Jezava caves in Eastern Serbia was performed four times a year. All identified phototrophic representatives were assigned to a certain division or group. The relationship between documented groups and different measured, determined and observed ecological parameters was illustrated using principal component analysis (PCA). A high diversity of cyanobacteria and algae was observed as a result of seasonal sampling: 141 taxa in Samar and 61 taxa in Jezava Cave. Cyanobacteria were dominant in both caves (coccoid forms prevailing) and were followed by Bacillariophyta. Bacillariophyta were positively correlated with light intensity and sites where seeping water was present, and cyanobacteria with water content in biofilm, Chl a and relative air humidity. Higher diversity of phototrophs was documented in December and March, and lower in May and August in both caves with Chl a values having the same trend as the diversity of phototrophic microorganisms. This was especially the case with biofilms in which diversity was more prone to seasonal changes and where Cyanobacteria dominated. Only 24 taxa were documented during all four seasons in Samar Cave (Cyanobacteria, Bacillariophyta and Chlorophyta representatives) and three in Jezava Cave (Cyanobacteria only).

AB  - Phototrophic microorganisms from two caves in Serbia (Podpeć and Stopić) were examined. Samples were taken from the entrances where natural light was present, as well as from the inside caves near artificial light (lampenflora community). Cyanobacteria, Chlorophyta, Bacillariophyta and Xanthophyta were documented, with 51 taxa in total. The highest number of taxa recorded in the Cyanobacteria were coccoid cyanobacteria; Gleocapsa and Chroococcus were dominant. According to the redundancy analysis (RDA), Cyanobacteria were dominant at cave entrances while other groups (Chlorophyta, Bacillariophyta and Xanthophyta) were documented in lampenflora samples. Temperature, relative humidity, and light intensity were measured, as well as chlorophyll a concentrations and biofilm parameters (water, organic and inorganic matter content). Ecological parameters did not show significant variation, while light intensity de-pended on the position of sampling sites. RDA showed that the water content was higher in biofilm samples from cave entrances, while levels of inorganic matter were increased in lampenflora samples. The concentration of chlorophyll a did not show significant correlations with any of the measured ecological or biofilm parameters. Although the ecological parameters inside the cave did not show significant variation, they should be monitored because of the potential influence on the development of the lampenflora community that has a negative aesthetic impact on cave formations.

AB  - Phototrophic microorganisms can be found in biofilms at entrances to caves where they have access to sufficient
sunlight, water and nutrients; however, they can also be found inside caves, where they are carried by animals and people, and
can proliferate in the presence of artificial light. Although the genus Humidophila includes some well-known cosmopolitan
species, further exploration of its rare, insufficiently investigated representatives in different geographical areas and unusual
habitats is necessary. Caves remain unknown, little-explored habitats, and many species currently known to science were
recorded for the first time. This study aimed to report species belonging to the genus Humidophila that were identified in
19 caves in Serbia. A total of ten species of this genus were recorded and some of them are documented for the first time
in Serbia. The most abundant species were H. contenta (found in 16 caves), H. paracontenta, and H. aerophila (found in 13
caves), whereas H. pyrenaica was identified in only one cave. The rare species, H. brekkaensoides and H. vidalii, were also
documented and described, but with different dimensions from those provided in current identification keys.

AB  - Iron oxide, in the form of magnetite (MG)–functionalized porous wollastonite (WL), was used as an adsorbent for heavy metal ions (cadmium and nickel) and oxyanions (chromate and phosphate) removal from water. The porous WL was synthesized from calcium carbonate and siloxane by controlled sintering process using low molecular weight submicrosized poly(methyl methacrylate) as a pore-forming agent. The precipitation of MG nanoparticles was carried out directly by a polyol-medium solvothermal method or via branched amino/carboxylic acid cross-linker by solvent/nonsolvent method producing WL/MG and WL-γ-APS/MG adsorbents, respectively. The structure/properties of MG functionalized WL was confirmed by applying FTIR, Raman, XRD, Mössbauer, and SEM analysis. Higher adsorption capacities of 73.126, 66.144, 64.168, and 63.456 mg g−1 for WL-γ-APS/MG in relation to WL/MG of 55.450, 52.019, 48.132, and 47.382 mg g−1 for Cd2+, Ni2+, phosphate, and chromate, respectively, were obtained using nonlinear Langmuir model fitting. Adsorption phenomena were analyzed using monolayer statistical physics model for single adsorption with one energy. Kinetic study showed exceptionally higher pseudo-second-order rate constants for WL-γ-APS/MG, e.g., 1.17–13.4 times, with respect to WL/MG indicating importance of both WL surface modification and controllable precipitation of MG on WL-γ-APS.

AB  - The industries of leather-tanning, mining and textile dyeing, generate large amounts ofchromium-containing wastewater. Hexavalent Cr(VI) is highly poisonous and extremelymobile in the surface-water and groundwater in a broad pH range and therefore it hasbeen identified as a potentially carcinogenic substance. The aim of the presented workwas to develop cellulose-based membrane functionalized with magnetite, which couldbe used as an efficient adsorbent for the removal of hexavalent chromium Cr(VI) ionsfrom aqueous solutions. Cellulose-based filter (CF) was functionalized with magnetitein three-step process. In the first and second step CF surface was modified usingan ethanolic solution of (3-aminopropyl)triethoxysilane (APTES), anddiethylenetriaminepentaacetic acid dianhydride, respectively. The introduction of aminoand carboxylic groups provided successful precipitation of magnetite in the third step.The obtained cellulose-magnetite membrane (CelMag-M) was characterized by FTIRand SEM analysis. Adsorption of Cr(VI) onto CelMag-M was studied using batchadsorptiontest. Under optimum pH conditions, the maximum experimental adsorptioncapacity of CelMag-M for Cr(VI) was found to be 111.2 mg g–1. The adsorption processwas endothermic, the equilibrium adsorption data could be best fitted to the Langmuiradsorption isotherm model and kinetics was in agreement with the pseudo-second-orderrate equation.

AB  - The term bottled water applies for water packaged in a health-correct packaging available in the market for
human consumption. Consumers still have insufficient knowledge of the importance of certain water
ingredients and their harmful or beneficial effect on the human organism. There is not enough expert
information about the harmfulness of certain ingredients in the water, even if many countries of the world have
adopted legal acts in which quality parameters of bottled water are standardized1. In such declared water,
physiological characteristics of water, redox status and the consequences of bad health effects are neglected
due to excessive consumption of waters with high mineral content. Due to the increased content of mineral
substances and high sodium intake, the allowed daily intake should be declared for water loaded with mineral
substances. The oxide-reduction potential of water, EROX, represents the mixed potential of all present redox
pairs and directly affects the behavior of water relative to the agents with it comes into contact. In this research,
we measured all parameters that define redox status: pH value, redox potential and rH2 factor in a wide range
of bottled waters available on the market of the Republic of Serbia. The substances that are declared as
potentially toxics2 were detected by HPLC-MS/MS. The results pointed to the necessity of a detailed
declaration of bottled water to decrease the possible consequences of bad effects on health due to excessive
consumption of water rich with minerals.

potentially toxics2 were detected by HPLC-MS/MS. The results pointed to the necessity of a detailed
declaration of bottled water to decrease the possible consequences of bad effects on health due to excessive
consumption of water rich with minerals.",

AB  - Bipolar electrochemistry (BPE) is an unconventional method to address conducting and semiconducting
particles in a wireless manner1. Unique features of BPE when compared to conventional electrochemical setup
where electrochemical reactions take place at the surface of two different electrodes both connected to a
potentiostat, allow us to address bipolar electrode electrochemically in a wireless fashion because there is no
direct connection with the power supply (see Figure 1.). Herein, we used the concept of BPE for the
electrochemical remediation of cyanotoxins following the formed products by HPLC-MS/MS. Due to the high
toxicity of cyanotoxins presenting potential global health problem, highly efficient remediation methods have
been under development in recent years, with advanced oxidation processes focused on mineralization as major
target. Electrochemical remediation arose as an interesting alternative with few reported protocols to date.

AB  - In the research phase of nuclear materials from the Backa area (NW of Serbia), hydrogeochemical prospecting was applied, which covers an area of about 500 km2. Samples were collected from surface water, from sources and wells, and bores. Combined hydrogeochemical methods included the examination of U, Ra, Pb, Zn, Cu, Mo, Li, Sr; anions HCO3-, SO42-, Cl-; cations Ca2+, Mg2+, Na+, K+, as well as the determination of SiO2, Eh, Ep and pH values. Additional testing determined the water content: NO3, F, Br, J, P. Value content of uranium (U) varied in the range of 0.1 - 125 ppb; Ra 0.026 - 0.33 Bq/l; Rn 1.45 - 32.63 Bq/l. At selected locations the uranium content in the A - horizon (15 - 20 cm) were determined. According to the geological and structural characteristics of the research area, results are shown on the maps in scale of 1:50000 and on appropriate diagrams and tables. The aim of this study was the application of geochemical prospecting method for the identification of geopathogenic zones of the influence of natural radionuclides in the rural settlements environment.

AB  - Hyperalkaline (pH>10.5) springs are extremely rare. There are only about ten in the entire world. This type of water has been identified in an ultramafic massif in central Serbia, on Mt. Studena, during the course of investigations conducted in 2017. The investigations included prospecting, terrain mapping and sampling, followed by assessment of data collected in situ and from laboratory analyses. The hyperalkaline spring is of the ascending type, its yield is very low (~0.05 L/s), and the water emerges in a diffuse fashion along fractures. The spring water is of the Ca-OH type, the pH level is 11.6 and the water temperature 11.2°C. The drainage area of the spring, like the entire Mt. Studena, is built up of Paleozoic ultramafic rocks, which geotectonically belong to the External Vardar Subzone. The spring is situated in the floodplain of the Brezanska River, whose channel is the local base level of erosion. The primary point of groundwater emergence is in solid ultramafic rocks, within a zone of fractures up to 0.5 mm wide, over a land area of ~1.5 m2. The paper describes a conceptual model of the formation of hyperalkaline water for the ascending spring in the ultramafic valley of the Brezanska River, on the northern slopes of Mt. Studena. The pH level of the groundwater is indicative of contemporary serpentinization, deep groundwater circulation and a prolonged contact between groundwater and ultramafic rocks along secondary fracture systems.

AB  - Iron oxide, in the form of magnetite (MG)–functionalized porous wollastonite (WL), was used as an adsorbent for heavy metal ions (cadmium and nickel) and oxyanions (chromate and phosphate) removal from water. The porous WL was synthesized from calcium carbonate and siloxane by controlled sintering process using low molecular weight submicrosized poly(methyl methacrylate) as a pore-forming agent. The precipitation of MG nanoparticles was carried out directly by a polyol-medium solvothermal method or via branched amino/carboxylic acid cross-linker by solvent/nonsolvent method producing WL/MG and WL-γ-APS/MG adsorbents, respectively. The structure/properties of MG functionalized WL was confirmed by applying FTIR, Raman, XRD, Mössbauer, and SEM analysis. Higher adsorption capacities of 73.126, 66.144, 64.168, and 63.456 mg g−1 for WL-γ-APS/MG in relation to WL/MG of 55.450, 52.019, 48.132, and 47.382 mg g−1 for Cd2+, Ni2+, phosphate, and chromate, respectively, were obtained using nonlinear Langmuir model fitting. Adsorption phenomena were analyzed using monolayer statistical physics model for single adsorption with one energy. Kinetic study showed exceptionally higher pseudo-second-order rate constants for WL-γ-APS/MG, e.g., 1.17–13.4 times, with respect to WL/MG indicating importance of both WL surface modification and controllable precipitation of MG on WL-γ-APS.

AB  - The study of the synthesis of anticorrosive inhibitors, based on chemically modified tannins, and
their use in alkyd based coatings to improve anticorrosive properties is presented in this work.
Two methods of tannin modification were applied: direct method using ammonium hydroxide,
ammonium hydroxide/ammonium chloride buffer or diethylenetriamine (DETA); and a two-step
method including tannin modification with epichlorohydrin (ECH) in first step to produce epoxy
modified tannin, ET, and further modification with heteroaromatic amines or linseed oil fatty acids
(LFA) in second step. The obtained anticorrosive additives were characterized using ATR-FTIR,
1H and 13C NMR spectroscopies and elemental analysis. Epoxy, amino, hydroxyl, acid and iodine
values of the synthesized inhibitors were determined according to standard methods. The
prepared alkyd coating with tannin inhibitors was tested according to standard SRPS EN ISO
4628 method. Anticorrosive coating containing modified tannin based additive showed increased
anticorrosive properties, good adhesion and coverage comparing to the coating with zinc
phosphate additive. The alkyd coating films based on ET-LFA and ET modified with 2-amino-5-
mercapto-1,3,4-thiadiazole showed best anticorrosive results.

AB  - Due to life in extreme environments, cyanobacteria and algae from cave biofilms that form at the entrances or deep inside the cave around artificial lights are of increasing interest to many scientists. It is well-known that many phototrophic microorganisms are first to colonize exposed substrata and produce the organic matter on which other biofilm constituents relly. Many studies dealing with phototrophic microorganisms from biofilms focus on the diversity and community composition of cyanobacteria and algae, while quantitative assessments are rarely implemented. Biofilm sampling was conducted in Degurić and Vernjikica Cave located in Western and Eastern Serbia, respectively. Ecological parameters (temperature, relative humidity, light intensity) and distance from the entrance were measured. Additionally, chlorophyll content, as well as biofilm parameters (water content, organic and inorganic matter) were determined. The abundance of phototrophic microorganisms was assessed on microscope slides which contained 1 mg of biofilm that was dehydrated for a short period of time and homogenized prior to slide preparation, and then rehydratated. The biomass of recorded cyanobacterial and algal taxa was calculated by applying geometric approximations and standard mathematical formulas. In Degurić Cave, at the sampling site where the highest biomass was documented, the higher diversity, water content and chlorophyll values were also recorded, while in Vernjikica Cave a high content of organic matter was documented. According to the multivariate analyses performed, the biomass of simple trichal Cyanobacteria, Bacillariophyta, and Xanthophyta was positively correlated with the content of organic matter in biofilm and light intensity, while coccoid and heterocytous Cyanobacteria and Chlorophyta showed a positive correlation with water content in the biofilm, relative humidity and distance from the entrance. The total biomass was positively correlated with the chlorophyll content, organic matter and light intensity, and negatively with the distance from the entrance.

AB  - Investigations focusing on wellhead encrustations within select zones of emergence of mineral water, in different hydrogeological provinces, were conducted from 2014 to 2017 in Serbia. They included: well BB-1 in Bogatić (Inner Dinaric Alps of western Serbia), wells LB-4 and LB-5 in Lukovska Banja (Šumadija-Kopaonik-Kosovo Province), and wells VG-2 and VG-3 in Vranjska Banja (Serbian Crystalline Core). The studied occurrences belong to the group of hot mineral waters, with temperatures ranging from 62°C to 93.9°C, and total dissolved solids (TDS) from 600 to 1267 mg/L. They are mildly acidic to mildly alkaline (pH 6.6 – 8.0) and their genetic types are HCO3 --Na++K+ (Bogatić and Lukovska Banja) and SO4 2-, HCO3 --Na++K+ (Vranjska Banja). Macroscopic, optical and diffraction assessment revealed that the encrustations comprised calcite and aragonite minerals, along with some local quartz, muscovite, albite and clinochlore. The conclusion was that there was a predominant presence of calcium carbonate in all the occurrences, represented by crystalline calcite grains, characteristically birefractive, and dark, semitranslucent grains in the form of microcrystalline calcite highly stained by iron hydroxides (Bogatić), as well as crystalline calcite with radially developed carbonate - aragonite (Lukovska Banja) and rod-like and filamentous aggregates of aragonite and calcite, highly translucent in places (Vranjska Banja).The texture of the samples exhibits alternating horizontal or wavy carbonate laminae. In Vranjska Banja, they include thin micritic to medium crystalline laminae and laminae composed of aggregates of aragonite needles in the form of bunch. In Bogatić and Lukovska Banja, there are thick micritic and highly porous laminae, 0.025 to 1 mm thick, or interlayers of a coarser crystalline structure. Apart from encrustations, all the occurrences exhibit phototrophic microbial mats, which were analyzed by scanning electron microscopy. The onset and progress of encrustation are primarily influenced by the physical and chemical composition of the mineral water (T, pH, TDS, HCO3 -, Ca2+, CO2, etc.), as corroborated by hydrogeochemical modeling software PHREEQC 3.4.0. In addition, phototrophic biofilms might be contributing to the creation and accumulation of minerals in the encrustations.

AB  - Levulinic acid (4-oxopentanoic acid) (LA) is a two-functional γ-keto acid widely used in a production of pharmaceuticals, ethyl levulinate, the substance which is
widely used in the cream and perfume industry, polymers, plasticizers, biofuel, resins, and various other additives.
LA was synthesized by the dehydration of fructose in a strongly acidic aqueous medium, using diluted hydrochloric acid, and subjected to microwave irradiation at
different operational conditions. LA was further used in two subsequent steps of peroxidation and dehydration to obtain 3-hydroxypropanoic acid and maleic
anhydride (MA) and acrylic acid (AA), respectively, which could be used for acrylic ester synthesis which could be used as a monomer in a polyacrylate
production (Figure 1).

AB  - In the research phase of the geological status of the area of southeastern Banat, samples were collected from surface waters, wells, and lakes. The content of U, Ra, Rn is determined in water. The sampling network was adjusted to the hydrographic characteristics of the terrain, and a hydrogeochemical map has been made at a scale of 1:50 000. In addition to hydrogeochemical prospecting, samples of the soil river sediments were taken to determine the profile of the coast of the following lakes: Vračarevo, Šaransko, Bagersko and Veliko lake. The regional hydrogeochemical prospecting included the area of the Bela Crkva, which drained the sediments of Negotin and Kvartara. In this area and wider, in accordance with the results of regional investigation, semi-geological and semi-geochemical research was carried out to identify resources of mineral deposits as well as the sources for water supply of rural settlements. During research, samples of water from surface streams, sources, wells, lakes, water reservoirs, creek sediments and wall samples were collected and examined.
AB  - U fazi istraživanja geološkog statusa područja jugoistočnog Banata, prikupljeni su uzorci sa površinskih akvatorija, bunara i jezera. U vodi je determinisan sadržaj U, Ra, Rn. Mreža uzorkovanja je prilagođena hidrografskim karakteristikama terena, i napravljena je hidrogeohemijska mapa 1:50 000. Pored hidrogeohemijske prospekcije, uzeti su uzorci rečnih sedimenata zemljišta kako bi se odredio profil obale sledećih jezera: Vračarevo, Šaransko, Bagersko i Veliko jezero. Regionalna hidrogeohemijska prospekcija obuhvatila je područje Bele Crkve, koje dreniraju sedimente Neogena i Kvartara.

abstract = "In the research phase of the geological status of the area of southeastern Banat, samples were collected from surface waters, wells, and lakes. The content of U, Ra, Rn is determined in water. The sampling network was adjusted to the hydrographic characteristics of the terrain, and a hydrogeochemical map has been made at a scale of 1:50 000. In addition to hydrogeochemical prospecting, samples of the soil river sediments were taken to determine the profile of the coast of the following lakes: Vračarevo, Šaransko, Bagersko and Veliko lake. The regional hydrogeochemical prospecting included the area of the Bela Crkva, which drained the sediments of Negotin and Kvartara. In this area and wider, in accordance with the results of regional investigation, semi-geological and semi-geochemical research was carried out to identify resources of mineral deposits as well as the sources for water supply of rural settlements. During research, samples of water from surface streams, sources, wells, lakes, water reservoirs, creek sediments and wall samples were collected and examined., U fazi istraživanja geološkog statusa područja jugoistočnog Banata, prikupljeni su uzorci sa površinskih akvatorija, bunara i jezera. U vodi je determinisan sadržaj U, Ra, Rn. Mreža uzorkovanja je prilagođena hidrografskim karakteristikama terena, i napravljena je hidrogeohemijska mapa 1:50 000. Pored hidrogeohemijske prospekcije, uzeti su uzorci rečnih sedimenata zemljišta kako bi se odredio profil obale sledećih jezera: Vračarevo, Šaransko, Bagersko i Veliko jezero. Regionalna hidrogeohemijska prospekcija obuhvatila je područje Bele Crkve, koje dreniraju sedimente Neogena i Kvartara. U ovom području i šire, u skladu sa rezultatima regionalnih ispitivanja, obavljena su i poludetaljna geološka-geohemijska istraživanja u cilju identifikacije ležišta mineralnih sirovina, kao i izvorišta za vodosnabdevanje ruralnih naselja.

AB  - The term bottled water refers to the water that is packaged in a health-correct packaging and that is available on the market for
human consumption. Consumers still have insufficient knowledge of the importance of certain ingredients and their harmful or
beneficial effects on the human body. Nowdays there are many legal acts in the world that regulate the quality of bottled water. In
order to assess the impact of packaging quality on the quality of bottled water, it is necessary to look at the regulation, both in the
field of water and in the field of packaging polymer. The information provided on the declaration is insufficient to see the quality of
the bottled water itself, and there is no indication of the potential toxic elements that can migrate from the packaging into the water.
Although PET is considered as inert material according certain components that are added to PET production can migrate in the
water, that must be regurarly controlled. Declarations of such products must follow the updating and monitoring of potentially toxic
parameters in accordance with European and world regulations. The impact of packaging, transport and storage on the change of
bottled water quality from the aspect of potentially toxic substances has been shown in many studies in the world, however, studies
of this type are rare in our country.

AB  - The term bottled water means water packed in a health-correct packaging and available
in the market for human consumption. Consumers still have insufficient knowledge of
importance of the certain ingredients and their harmful or beneficial effect on the human
organism. There is not enough expert information about the harmfulness of certain
ingredients in the water, but many countries in the world have adopted legal regulations
in which quality parameters of bottled water are standardized (EEC, WHO1, EPA,
IBWA, FDA). The race for profit and the lack of necessary quantities of bottled waters
moved declarations in to the second plan. The declaration on bottled waters should
describe also the physiological characteristics, since the consumption of high-mineral
water may lead to adverse effects on the health of consumers, primarily children. In such
declared water, missing physiological characteristics of water, redox statuses, and
possible consequences on the health, are neglected due to excessive consumption of
waters with high mineral content. Due to the increased content of mineral substances
and high sodium intake, the allowed daily intake should be declared for water loaded
with mineral substances. Redox status of water represents a health factor and it is
completely defined by the pH value, redox potential and rH2 factor, parameters which
were the subject of this study in this work. The oxide-reduction potential of water, EROX,
represents the mixed potential of all present redox pairs and directly affects the behavior
of water relative to the agents to which comes into contact2. The results pointed to the
necessity of a fuller declaration of bottled water, because in that case bottled water
gained in importance and would decrease the consequences of the possible bad effects
on health due to excessive consumption of water rich with minerals. Test results
demonstrated that our market has a wide range of bottled waters, and that the health
aspect can be estimated through the oxidation-reduction properties.

AB  - Bipolar electrochemistry (BPE) is an unconventional method to address conducting and
semiconducting particles in a wireless manner. Unique features of BPE when compared
to conventional electrochemical setup where electrochemical reactions take place at the
surface of two different electrodes both connected to a potentiostat, allow us to address
bipolar electrode electrochemically in a wireless fashion because there is no direct
connection with the power supply (see Figure 1.). Herein, we used the concept of BPE
as a straightforward way for the site selective deposition of materials on bipolar
electrodes. Furthermore, we use these materials for the electrochemical remediation of
cyanotoxins, a potential global health problem, exploiting the versatility of bipolar
electrochemistry. Due to the high toxicity of cyanotoxins, highly efficient remediation
methods have been under development in recent years, with advanced oxidation
processes focused on mineralization as major target. Electrochemical remediation arose
as an interesting alternative with few reported protocols to date.

AB  - The presence of biofilms on stone monuments can lead to biodeterioration processes that significantly lower not only the aesthetic value of cultural heritage sites but also cause considerable physical and chemical damage to stone surfaces. In terrestrial environments, cyanobacteria have a significant role in biofilm formation on a variety of natural and artificial stone substrata, including granite, sandstone, limestone, lime mortar, etc. Studies on cyanobacterial diversity and estimation of biodeteriorative activity on stone cultural heritage objects can be very important for conservators and restorers, and cyanobacteria removal from stone monuments is currently a great challenge for conservation science. In that sense, the diversity of terrestrial cyanobacteria was investigated at six localities in Serbia. Samples for cyanobacterial analyses were taken from surface biofilms covering different substrata: granite and lime mortar (The Monument to the Unknown Hero), sandstone (Branko's Bridge, Eiffel's Lock) and carbonate rock (Medieval tombstones from Mramorje and Rastite, Gradac Monastery). A total of 18 cyanobacterial taxa were identified. The highest diversity was found on carbonate rock, followed by sandstone. Cyanobacteria were also recorded on an artificial substratum - lime mortar, while cyanobacteria were not found on granite. All detected cyanobacteria seriously impaired the structural and aesthetic integrity of the studied monuments via mechanical and chemical actions, so their presence must not be overlooked.

AB  - Predmet ove doktorste disertacije je analiza zajednice aerofitskih cijanobakterijai algi iz biofilma sa stenovitog supstrata ulaza petnaest odabranih pećina iz Srbije kao inekoliko tačaka u blizini veštačkog osvetljenja. Akcenat istraživanja bio je nafototrofnim mikroorganizmima iz biofilma, dok su kao dodatak endolitski predstavniciidentifikovani iz nekoliko uzoraka stene. Analizirana je i morfologija, stepenrazvijenosti biofilma, kao i udeo sadržaja vode, organske i neorganske materije ubiofilmu. U svim pećinama, mereni su ekološki parametri i određene su primarnaprodukcija (preko koncentracije hlorofila a) i petrografska analiza stenovitog supstrata.Na odabranim uzorcima rađena je kvantitativna i sezonska analiza cijanobakterija i algi.Statističke analize su poslužile kao alat za sagledavanje odnosa zabeleženih fototrofnihmikroorganizama i različitih ekoloških i opisnih parametara.Zabeleženo je prisustvo ukupno 290 taksona cijanobakterija i algi koje susvrstane u 4 razdela: Cyanobacteria (134 taksona, od kojih 82 taksona pripadakokoidnim formama), Bacillariophyta (129 taksona), Chlorophyta (26 taksona) iXanthophyta (1 takson). Najveći broj taksona Cyanobacteria zabeležen je u rodovimaGloeocapsa, Chroococcus, Gloeothece, Leptolyngbya i Scytonema.

AB  - The aim of this PhD thesis is the analysis of the aerophytic cyanobacterial andalgal community from biofilm developed on stone substrate at the entrance of fifteenselected caves from Serbia and several sites near the artificial light in caves. The focusof the study was on phototrophic microorganisms from the biofilm, while endolithicrepresentatives were additionaly identified from several stone samples. Morphology,degree of biofilm development, as well as the content of water, organic and inorganicmatter in biofilm were also observed. At all sampling sites, ecological parameters,primary production (through concentration of chlorophyll a), as well as petrographicanalysis of rocky substrates were measured and determined. Quantitative and seasonalanalyzes of cyanobacteria and algae were assessed in selected samples. Statisticalanalyzes have served as a tool for examining the relationship between recordedphototrophic microorganisms and various ecological and descriptive parameters.A total of 290 cyanobacterial and algal taxa were recorded and classified into 4divisions: Cyanobacteria (134 taxa, of which 82 taxa belong to the coccoid forms),Bacillariophyta (129 taxa), Chlorophyta (26 taxa) and Xanthophyta (1 taxon). Thehighest number of cyanobacterial taxa was documented within the following genera:Gloeocapsa, Chroococcus, Gloeothece, Leptolyngbya and Scytonema. Luticola andHumidophila were the most diverse genera within Bacillariophyta division, while inChlorophyta Cosmarium had the highest number of species.A new cyanobacterial taxon, Nephrococcus serbicus S. Popović, G. SubakovSimić & J. Komárek, sp. nov., was described from a biofilm sample of Božana Cave.This also represents the first record of the genus Nephrococcus in Europe.Cyanobacteria were dominant in all caves, except Rćanska and Bogovinskacave. The largest number of Bacillariophyta and Chlorophyta was recorded in theRćanska cave (due to the presence of water on samplins sites) and in the Samar Cave(due to seasonal sampling). The significance of the seasonal biofilm sampling in Samarand Jezava caves is primarily reflected through the higher diversity of aerophyticcyanobacteria and algae in comparison to other caves...

AB  - The ionic content was examined in nine aqueous tea extracts in which time of boiling, acidification of the medium using lemon juice and way of preparation were observed as factors. Ion chromatography was used for determination of inorganic anion content, and data were processed using CANOCO program for multivariate analysis. The variations in ionic content were observed among different tea samples. The highest concentrations of chloride, nitrate, phosphate, and sulphate ions were found in nettle, while the highest concentrations of fluorides were detected in elderflower tea infusion. The effect of boiling time (5, 10, and 20 min), acidification of the medium and different preparation procedure (boiling and cooling at room temperature) were statistically presented using principal component analysis. The examined factors did not have a significant effect on the ionic concentration in tea infusions.
AB  - Јонски садржај испитиван је код девет водених раствора чаја, при чему је на екстракцију јона посматран утицај дужине кувања, киселости средине (која је постигнута додатком лимуновог сока) и начинa припреме. Јонска хроматографија коришћена је за одређивање садржаја неорганских анјона, а пoдаци су обрађени помоћу Canoco програма за мултиваријациону анализу. Јонски садржај варира код различитих узорака чаја. Највеће концентрације хлоридних, нитратних, фосфатних и сулфатних јона одређене су у коприви, док су највеће концентрације флуорида одређене у инфузији кантариона. Утицај времена кључања (5, 10 и 20 мин.), киселост медијума и различити начини припреме (кључање и хлађење на собној температури) статистички су приказани помоћу анализе главних компоненти. Испитивани фактори нису имали значајан утицај на јонску концентрацију у чајним инфузијама.

AB  - Gelatin hydrogels have great potential in regenerative medicine but their weak mechanical properties are a major drawback for the load-bearing applications, such as scaffolds for tissue engineering. To overcome this deficiency, novel biodegradable hydrogels with improved mechanical properties were prepared by combining gelatine with 2-hydroxyethyl methacrylate (HEMA), using a double network synthetic procedure. The first, superporous and mechanically strong network, was obtained by free radical polymerization of HEMA at cryogenic temperature, in the presence of gelatin. Degradable poly (beta-amino ester) (PBAE) macromers of different chemical composition or molecular weight were used as crosslinkers to introduce hydrolytically labile bonds in PHEMA. The second gelatin network was formed by crosslinking gelatin with glutaraldehyde. For comparison, a set of biodegradable PHEMA networks was obtained by polymerization of HEMA at cryogenic temperature. All samples were characterized revealing that mechanical strength, swelling behavior and degradation rate as well as high biocompatibility of new IPNs are in accordance with values required for scaffolds in tissue engineering applications and that tuning of these properties is accomplished by simply using different PBAE macromers.
