Savić, Snežana D. Savić (2021)Poor water solubility of new chemical entities is considered as one of the main obstacles in drug development, as it usually leads to low bioavailability after administration. To overcome these problems, the selection of the appropriate formulation technology needs to be based on the physicochemical properties of the drug and introduced in the early stages of drug research. One example of the new potential drug substance with poor solubility is DK-I-60-3, deuterated pyrazoloquinolinone, designed for the treatment of various neuropsychiatric ...... ć 6, Ivana Pantelić 1 , James M.

Jelena R. Mitrović, Maja Bjelošević Žiberna, Aleksandar Vukadinović, Daniel E. Knutson, Dishary Sharmin, Aleksandar Kremenović, Pegi Ahlin Grabnar, Odon Planinšek, Dominique Lunter, James M. Cook, Miroslav M. Savić, Snežana D. Savić (2023)Recently, nanocrystal dispersions have been considered as a promising formulation strategy to improve the bioavailability of the deuterated pyrazoloquinolinone ligand DK-I-56-1 (7‑methoxy-2-(4‑methoxy-d3-phenyl)-2,5-dihydro-3H-pyrazolo[4,3-c]quinolin-3-one). In the current study, the freeze-drying process (formulation and process parameters) was investigated to improve the storage stability of the previously developed formulation. Different combinations of lyoprotectant (sucrose or trehalose) and bulking agent (mannitol) were varied while formulations were freeze-dried under two conditions (primary drying at -10 or -45 °C). The obtained lyophilizates were characterized in terms ...... Aleksandar Vukadinović, Daniel E.

Anisotropic grossular–andradite garnets: Evidence of two stage skarn evolution from Rudnik, Central Serbia
This paper presents LA-ICP-MS data for garnets from the Rudnik skarn deposit (Serbia), which range from Grs45–58Adr40–52Alm2–3 in the core and Adr70–97Grs2–29Sps1 in the rim displaying anisotropy and zoning. In spite of wide compositional variations the garnets near the end-member of andradite (Adr > 90) are generally isotropic. Fe-rich rims exhibit LREE depletion and flat HREE pattern with weak negative Eu anomaly, including higher As and W contents. On the other side, the Fe-poorer core shows flat REE pattern ......

Arsenopirit iz rudnih ležišta Šumadijsko-kopaoničke oblasti: paregeneza, sastav i produkti oksidacije
Ivana N. Jelić (2023)Arsenopirit, FeAsS je čest pratilac polimetaličnih orudnjenja Šumadijsko-kopaoničke oblasti. Jedan je od sulfida koji u najvećoj meri koncentriše zlato. Nepoželjan je u rudama jer njegovom oksidacijom na jalovištima može doći do oslobađanja arsena koji spada u elemente toksične za životnu sredinu. U okviru ovog doktorata sistematski su ispitivani arsenopiriti iz različitih stadijuma i tipova orudnjenja rudnih ležišta i mineralizacija Šumadijsko-kopaoničke oblasti (Rudnik, Sastavci, Trepča, Gokčanica – Drenjak i Rujak, Golijska reka i Jurija).

Crystallography and Surface Oxidation of Stoichiometric Arsenopyrite from Šumadija-Kopaonik Pb-Zn/Polymetallic Ore District (Serbia)
Ivana Jelić, Aleksandar Pačevski, Aleksandar Kremenović, Aleš Šoster, Andreja Šestan, Janez Zavašnik (2023)The behaviour and stability of arsenopyrite largely depend on its crystal structure, but studies of crystallography and structural defects are scarce. For clarification, we investigated a series of natural arsenopyrite crystals from the polymetallic Pb-Zn-(±Cu,Ag,Au,Sb,Bi,W) Šumadija-Kopaonik ore district (Serbia) by powder X-ray diffraction (XRPD). Among them, samples from the Drenjak gold mineralisation showed near-stoichiometric FeAsS composition and were further investigated by conventional and high-resolution transmission electron microscopy methods.

Pleistocene rhinoceros from Bogovina Cave: the first report of Stephanorhinus hundsheimensis Toula, 1902 (Mammalia, Rhinocerotidae) from Serbia
Finds of Pleistocene rhinoceros are rare in Serbia, and only one species (the woolly rhinoceros Coelodonta antiquitatis Blumenbach, 1799) has been reported so far. The current paper presents the dental material of an extinct so-called Hundsheim rhinoceros, Stephanorhinus hundsheimensis Toula, 1902 from Bogovina Cave (East ern Serbia). Both the morphological and metric characteristics of the teeth are consis tent with the attribution to S. hundsheimensis.

Утицај промене нивоа подземне воде за услове плитког фундирања у крупнозрном тлу
Милана Мичета (2024)Подземне воде представљају изузетно важан природни ресурс, као и важну компоненту система, којим је представљено тло. У складу са тим, приликом пројектовања плитких темеља на крупнозрном тлу, односно приликом анализе граничне носивости и слегања, треба узети у обзир и утицај воде. Верује се да ниво подземне воде значајно смањује носивост тла, док се слегања значајно повећавају. Terzaghi (1943) је први сугерисао да се потапањем масе тла, његова носивост смањује за половину, док се слегање удвостручује.

The oil industry and climate changes
Dejan Radivojević (2020)Uprkos tome što je problem klimatskih promena poznat dugi niz godina i dalje veliki broj ljudi poistovećuje pojam vremenskih prilika sa klimom ne uzimajući u obzir različitu dužinu njihovog trajanja. U medijima se vrlo često mogu naći katastrofična predviđanja vezana za zagrevanje naše planete usled neodgovornog ponašanja čoveka. Sa druge strane geolozi znaju da je tokom geološke prošlosti naše planete bilo mnogo toplijih intervala od današnjih kao i da ti intervali nisu neminovno rezultovali masovnim izumiranjem živog sveta već su ...... org/10.1098/rsta.2012.0294 D.

Mineragenija i potencijalnost karbonatnih sirovina rudnog reona Bjelopavlića (Crna Gora)
Darko M. Božović (2016-09-28)Karbonatne sirovine, obzirom na geološku građu Crne Gore predstavljaju jednu od najznačajnijih nemetaličnih mineralnih sirovina. U Crnoj Gori postoje brojna leţišta karbonatnih sirovina (arhitektonsko - građevinskog i tehničko - građevinskog kamena) koja su istraţena ili su u eksploataciji, među kojima rudni reon Bjelopavlića zauzima najznačajnije mjesto.Dosadašnja istraţivanja karbonatnih sirovina na ovom području imala su, međutim, prevashodno uzak istraţivački cilj, utvrđivanje rezervi arhitektonsko - građevinskog i tehničko - građevinskog kamena određenog leţišta, ili preliminarna ispitivanja kvaliteta krečnjaka u njima, sa ...karbonatne mineralne sirovine, arhitektonsko - građevinski kamen, tehničko - građevinski kamen, karbonatna punila, rudni reon Bjelopavlića, potencijalnost....

A comparative study of the molecular and isotopic composition of biomarkers in immature oil shale (Aleksinac deposit, Serbia) and its liquid pyrolysis products (open and closed systems)
Gordana Gajica, Aleksandra Šajnović, Ksenija Stojanović, Jan Schwarzbauer, Aleksandar Kostić, Branimir Jovančićević (2021)The molecular and isotopic composition of biomarkers in initial bitumen isolated from immature (0.41% Rr) oil shale samples (Aleksinac deposit) and liquid products obtained by pyrolysis in open (OS) and closed (CS) systems are studied. The influence of pyrolysis type and variations of kerogen type on biomarkers composition and their isotopic signatures in liquid products is determined. The applicability of pyrolysis type, numerous biomarkers and carbon isotopic compositions (δ13C) of n-alkanes in liquid pyrolysates is established.
