Influence of Post-Synthesis Treatments on the Properties of Brushite/Monetite Powders
Željko Radovanović, Lidija Radovanović, Aleksandar Kremenović, Đorđe Janaćković, Rada Petrović (2022)Dicalcium phosphate (DP) materials, of which brushite and monetite were the most known, have been intensively studied for several decades because of excellent resorptive and osteoconductive properties that can satisfy the requirements needed for various medical applications, such as bone cements, coatings of metallic implants and bone grafts ...Željko Radovanović, Lidija Radovanović, Aleksandar Kremenović, Đorđe Janaćković, Rada Petrović.

Electronic Dictionaries - from File System to lemon Based Lexical Database
In this paper we discuss some well-known morphological descriptions used in various projects and applications (most notably MULTEXT-East and Unitex) and illustrate the encountered problems on Serbian. We have spotted four groups of problems: the lack of a value for an existing category, the lack of a category, the interdependence of values and categories lacking some description, and the lack of a support for some types of categories. At the same time, various descriptions often describe exactly the same ...... : 1. RelationName is a unique rule name and its identifica- tion, built upon a unique combination of other attribute values (e.g. VAR=IratiOvati V V); 2. RelationType is a type a variation: suffix variations, affix variations, etc.; 3. SuffixFrom / SuffixTo indicates suffixes (suf- fix variations) ...
... oxidate). In this way rule groups were introduced contain- ing rules that come in pairs. An example of a rule from this rule set is VAR=ArisatiIrati V V, which is applied to a verb that ends in -arisati and contains the marker VAR=ArisatiIrati (e.g. komentarisati ‘to comment’). The rule can be used ...

The lost freshwater goby fish fauna (Teleostei, Gobiidae) from the early Miocene of Klinci (Serbia)
Freshwater gobies played an important role in the Miocene paleolakes of central and southeastern Europe. Much data have been gathered from isolated otoliths, but articulated skeletons are relatively rare. Here, we review a rich assemblage of articulated gobies with abundant otoliths in situ from the late early Miocene lake deposits of Klinci in the Valjevo freshwater lake of the Valjevo-Mionica Basin of Serbia. The fauna was originally described by Anđelković in 1978, who noted many different fishes, including one ...Katarina Bradić-Milinović, Harald Ahnelt, Ljupko Rundić, Werner Schwarzhans.

Metodologija proračuna sanacije klizišta šipovima
Klizišta u Srbiji, u najvećem broju slučajeva, jako zavise od geoloških uslova u terenu i svako klizište ima svoje specifičnosti koje moraju da se odrede geotehničkim istraživanjima. Stoga su u radu prvo prikazane osnovne karakteristike klizišta u Srbiji, kao i postupci njihovog istraživanja. Zatim su prikazani proračuni sanacije klizišta vertikalnim šipovima. Metodologija proračuna je složena, jer podrazumeva interakciju klizišta i stabilizirajućih šipova. Prilikom određivanja bočne otpornosti tla oko šipova koristi se metoda Brinč Hansena koja uzima u obzir trodimenzionalne ...klizišta, geotehnička istraživanja, bočna nosivost šipova, interakcija klizišta i šipa, analiza stabilnostiSlobodan Ćorić, Dragoslav Rakić, Stanko Ćorić, Dušan Berisavljević.

Fuzzy expert analysis of the severity of mining machinery failure
Mining machinery failure is almost an everyday occurrence. Usually the failures bare certain consequences, which require additional financial costs to repair and restore the system to its operational state. The consequences are viewed through negative and damaging effects a failure has on the machine, health and safety of the employees, work environment, and on the environment. The removal of the consequences of the failure requires additional financial investment, which has a negative impact on the company’s business. In order ...Dejan V.

Svedoci smo toga da moderni problemi zahtevaju malo drugačiji pristup nego u prošlosti, odnosno zahtevaju moderna rešenja. Samim tim, vremenom je došlo do modernizacije alata,u ovom slučaju došlo je do razvoja modela za rasprostiranje buke koji su se vremenom unapređivali pa tako danas imamo jedno moćno sredstvo za borbu protiv buke u vidu kompjuterskog softvera.Ovaј master rad, pod nazivom „Modeliranje buke u urbanoj sredini ...... slika: N B 2 B 2 B 2 B 2 B 2 B 2 il C” C0 eo Fo P oO o g o o v g o i g o g v r u o g v p p p j u u J j J a l l a o l l š N M m i o i a o y e g p a g u W w q w j w w w v B w g g j p v p j p p p o v p w p a w „ : u a L S C c ) D m ” o r o . r r o O al: a2: a3: a4: ...

The number of unimodular roots of some reciprocal polynomials
Dragan Stankov (2020)We introduce a sequence P2n of monic reciprocal polynomials with integer coefficients having the central coefficients fixed. We prove that the ratio between number of nonunimodular roots of P2n and its degree d has a limit when d tends to infinity. We present an algorithm for calculation the limit and a numerical method for its approximation. If P2n is the sum of a fixed number of monomials we determine the central coefficients such that the ratio has the minimal limit. ...Algebraic integer, the house of algebraic integer, maximal modulus, reciprocal polynomial, primitive polynomial, Schinzel-Zassenhaus conjecture, Mahler measure, method of least squares, cyclotomic polynomialsDragan Stankov.

Determination of Mechanical Properties of Altered Dacite by Laboratory Methods
This paper presents a methodology for determining the uniaxial and triaxial compressive strength of heterogeneous material composed of dacite (D) and altered dacite (AD). A zone of gradual transition from altered dacite to dacite was observed in the rock mass. The mechanical properties of the rock material in that zone were determined by laboratory tests of composite samples that consisted of rock material discs. However, the functional dependence on the strength parameter alteration of the rock material (UCS, intact ......

Damage quantification of built stone on Dark Gate (Belgrade, Serbia): sample of damage index application for decay rate evaluation
The Dark Gate is the monument of culture, part of the cultural and historical complex of the Belgrade Fortress. It is constructed of limestone blocks that after 270 years of exposure to environmental conditions and different anthropogenic influences show wide ranges of decay forms. During 2007, detail registration of all built limestone microfacies and weathering forms was done using tools of monument mapping. A correlation scheme ‘‘intensity– damage category’’ was made according to the type, intensity, and distribution of ...... (2000) Deterioration of rock monuments in Petra/Jordan.

Granatski amfiboliti Bistrice
Jovana Opančina (2024)Predmet ispitivanja ovog završnog rada su granatski amfiboliti Bistrice. Izvršena su petrografska i hemijska ispitivanja s ciljem da se odredi stepen metamorfizma, protolit ispitivanih stena i P-T uslovi nastanka. Ispitivani granatski amfiboliti geografski pripadaju Prijepolju, tačnije nalaze se na ulasku u Prijepolje, mesto Bistrica. Geološka građa obuhvata uglavnom mezozojske tvorevine među kojima se nalaze sedimentne, magmatske i metamorfne stene. Geološki procesi koji su doveli do stvaranja amfibolita su procesi subdukcije i obdukcije koji su se pretpostavljamo dešavali na većim ...Jovana Opančina. Granatski amfiboliti Bistrice, 2024
