A WordNet Ontology in Improving Searches of Digital Dialect Dictionary
In this paper, we present a method for automatic generation of a digital resource, which connects all indirect synonyms of a dialect term to all indirect synonyms of a corresponding term in the standard language, aiming to improve the search of a digital dialect dictionary. The method uses SWRL rules defined in the Serbian WordNet ontology to identify sets of synonymous words. It also uses e-dictionaries to produce correct lemmas in standard language that users usually employ in searches. ...Miljana Mladenović, Ranka Stanković, Cvetana Krstev.

Rule-based Automatic Multi-word Term Extraction and Lemmatization
In this paper we present a rule-based method for multi-word term extraction that relies on extensive lexical resources in the form of electronic dictionaries and finite-state transducers for modelling various syntactic structures of multi-word terms. The same technology is used for lemmatization of extracted multi-word terms, which is unavoidable for highly inflected languages in order to pass extracted data to evaluators and subsequently to terminological e-dictionaries and databases. The approach is illustrated on a corpus of Serbian texts from ...Ranka Stanković, Cvetana Krstev, Ivan Obradović, Biljana Lazić, Aleksandra Trtovac.

Burnishing Versus Smoothing In Ceramic Surface Finishing: A Sem Study
From the Neolithic up to the present, people have used various methods to improve the surface of ceramic objects. In this study, we look specifically at smoothing and pattern burnishing of ceramics produced today by traditional methods. Optical microscopy and SEM show specific surface changes. Smoothing results in an irregular surface, which causes diffused reflection of light. Burnishing produces an even and compact surface, which causes specular reflection and lustre. The results can be used to infer methods of ...Ionescu Corina, Volker Hoeck, Crandell Otis N., Šarić Kristina.

Bioleaching Process for Copper Extraction from Waste in Alkaline and Acid Medium
Flotation wastes are becoming a valuable secondary raw material and source of many metals and semimetals worldwide with the possibilities of industrial recycling. The flotation tailings contain oxide and sulfide minerals that have not been sufficiently stabilized and form acidic mine waters, which in turn contaminate groundwater, rivers, and reservoi6sediments. An effective way to recycle these mine wastes is to recover the metals through leaching. While the focus is on acid bioleaching by iron- and sulfur-oxidizing bacteria, alkaline leaching, ...Ivica Ristović, Darina Štyriaková, Iveta Štyriaková, Jaroslav Šuba, Emilija Širadović.

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 ...Jelena R.

Техничка и биолошка рекултивација као технолошки процес рада у површинској експлоатацији на примеру ПК „Тамнава Западно Поље“ РБ Колубара
Вељко Божић (2024)Површинска експлоатација угља захтева управљање целокупним простором експлоатационог поља, како производњом угља, тако и одлагањем откривке. Рекултивација и реструктуирање ових маса нуди бројне могућности у избору и структуирању земљишта за потребе и циљеве човека и његове животне околине. Избор пост-експлоатационог начина коришћења земљишта треба заснивати на функционалним и социокултуралним потребама заједнице и окружења. Рекултивација представља комплекс рударских, инжењерских и пољопривредних мера које се спроводе за обнављање, па чак и побољшање, биолошке продуктивности и пољопривредне вредности терена нарушеног површинском експлоатацијом. ...Површинска експлоатација, Тамнав-Западно поље, техничка рекултивација, биолошка рекултивација, заштита животне средине... pamu poropHM Oarep SR. 2000 32/5 + VR, TpaHcnoprepH ca TpakoM B = 2000 mm u omunarau A-+R.-B 8500x60.
