Oптимизација положаја резних елемената роторних багера помоћу мерења термалном камером
Предраг Радуловић (2024)Роторни точак као радни елемент роторног багера представља један од најбитнијих делова багера. У овом раду појединачно су представљени сви делови радног елемента роторног багера као и типови и материјали од којих су израђени. Приказани су утицаји геолошке грађе и разних отпора приликом копања на резне елементе. Веома битан део рада представља термографија као дијагностичка метода као и студија случаја која је изведена, након извршених мерења чији у резултати приказани у раду.Крајњи исход рада представља предлог оптимизације положаја зуба ...Предраг Радуловић.

New Pliensbachian rhynchonellide (Brachiopoda) from Livari, (Rumija Mountain, Montenegro): taxonomy and shell microstructure implications
Barbara V. Radulović (2022)An interesting case of close external similarity (homoeomorphy) is revealed by the study of an Early Jurassic rhynchonellide brachiopod from Livari, Rumija Mountain, southern Montenegro. Shell microstructure was used as the primary diagnostic tool, applied before serial sectioning to study internal characters. Sepkoskirhynchia sphaerica gen. et sp. nov. is erected based on the presence of coarse fibrous shell microstructure and subfalciform crura. Because of these primary diagnostic characters, the new genus is placed in the rhynchonellide family Basiliolidae.

Middle Jurassic terebratulide brachiopods from the Jordan Valley (northwestern Jordan)
U radu je izvršena revizija i detaljan opis srednjojurskih brahiopoda Jordanske doline, a takodje su izdvojeni i novi taksoni. Sa profila Arda iz gornjeg bata (Hamam formacija) i donjeg keloveja (Muganija formacija) odredjeni su novi rod i vrsta Jordanithyris ardainensis. Iz gornjeg bata Hamam formacije (krečnjaci, dolomiti, peščari i laporci) izdvojena je vrsta Ptyctothyris quillyensis. Zajednica koju čine Arabatia bihinensis, Ectyphoria sinaiensis, Ptyctothyris quillyensis, Dorsoplicathyris dorsoplicata i Tubithyris jurayfahiensis potiče iz donjokelovejskih krečnjaka sa proslojcima laporaca Muganija formacije.

Callovian (Middle Jurassic) terebratulide brachiopods from the Jordan Valley (northwestern Jordan)
U radu je izvršena revizija srednjojurskih terebratulidskih brahiopoda Jordanske doilne, a takodje su spisku predhodne faune dodati i novi taksoni. Sa profila Tel el Dahab, iz kelovejskih stena (Muganija formacija) odredjeni su novi taksoni terebratulida: Kutchithyris simoni sp. nov. i Trigonithyris wilsoni sp. nov, koji su ovom prilikom opisani. Takodje, po prvi put se iz Jordana pominju i tri terebratulidske vrste: Bihenithyris barringtoni, Ptyctothyris daghaniensis i Sphriganaria cardioides koje su nadjene zajedno sa Bihenithyris weiri, a koje imaju šire ...Howard R.

The first record of nautiloids (Cenoceras intermedius) from the early Pliensbachian of Rgotina, (Getic nappe, eastern Serbia)
Cenoceras intermedius (J. Sowerby) is one of the most widespread species among the Early Jurassic nautiloid fauna and its geological range still controversial up to the present day. The specimen of Cenoceras intermedius from the sandy bioclastic limestones of Rgotina (Getic nappe of eastern Serbia), is a large half conch representing the phragmocone. Viewing our findings in light of previous results suggests the main morphological changes occurred during the ontogenetic evolution. The coiling starts with a round-square whorl section, ...Cephalopoda, Cenoceras intermedius, ontogenetic changes, geological range, northwestern Neo-Tethys, PliensbachianPaul Țibuleac, Barbara V.
