Aleksandar Mijatović, Angelina Z. Caković, Aleksandar Lolić, Olivera Klisurić, Marko N. Živanović, Dragana S. Šeklić, Snežana Sretenović, Marija Ilić, Jovana Bogojeski (2023)Cancer remains one of the world's deadliest diseases, claiming many lives each day. Transition metal complexes are leading candidates in developing anticancer agens with cisplatin used in chemotherapy worldwide. Copper, an endogenous metal in the human body, is especially attractive because of its typical redox biological activities and a relatively strong affinity to nucleobases. A series of Cu(II) complexes with ethane-1,2-diamine as the amine part and pentane-2,4-dione and/or 1-phenylbutane-1,3-dione, pentane-2,4-dione and/or 1,1,1- trifluoropentane-2,4-dione, or 1,1,1-trifluoropentane-2,4-dione and/or 1-phenylbutane-1,3-dione as the ...Aleksandar Mijatović, Angelina Z.

Medical Domain Document Classification via Extraction of Taxonomy Concepts from MeSH Ontology
Mihailo Škorić, Mauro Dragoni (2019)This paper is a result of a task that was presented to attendants of Keyword Search in Big Linked Data summer school, that was organized by Vienna University of Technology, under the Keystone COST action in the summer of 2017. It presents a specific approach to the classification via creation of minimal document surrogates based on the US National medical library’s MeSH ontology, which is derived from the Medical Subject Headings thesaurus. In a series of previously classified medically ...... and the second block 055 is unique among the sibling nodes (Figure 2). 1.2 Classification introduction The problem of classifying documents in general occurs in two variants: clas- sification in a well-known, restricted domain of classes, and in an unknown one. For both, the problem is reduced to ...

The ex- perimental method also considered the length of the identifiers, so they were replaced by a certain number of iterations ...

Stevan Đenadić, Dragan Ignjatović, Miloš Tanasijević, Uglješa Bugarić, Ivan Janković, Tomislav Šubaranović (2019)Availability is one of the most used terms in maintainability engineering. This concept is used to denote: The quality of service of an engineering system, i.e., machines, weak points’ analysis, asset management, as well as making decisions in the process of life cycle management. Availability is an overall indicator and contains partial indicators that are oriented towards reliability, maintenance, and logistical support. Availability presents a variable value and changes in time and space. Usually, availability is shown as the ...... machinery working in EPS (Electric Power Industry of Serbia) mines.

Korelacija magnetnog susceptibiliteta i sadržaja metala u flotacijskom jalovištu
Procena metala u rudama, jalovištu i zemljištu se tradicionalno određuje hemijskim metodama kao što su Rengen fluorescentna analiza (XRF), Instrumentalna neutronska aktivaciona analiza (INAA) i Masena spektrometrija induktivno spregnute plazme (ICP-MS). Neke od pomenutih metoda su veoma zahtevne i skupe, te se nametnula potreba ka traženju jeftinijeg alata za brzu procenu prisustva pojedinih metala. Tokom poslednjih nekoliko decenija, mnoge studije su pokazale da su magnetna merenja dovoljno osetljiva da detektuju magnetni signal feromagnetnih materijala, a samim tim i metala ...Filip Abramović, Vesna Cvetkov, Aco Ilić, Dragana Životić.
