The "Landfill 3" was formed at the location of the flotation tailing dump "Čukaru Peki", where the earthen material, created during the dam construction of the flotation tailing dump was placed. A ...part of the deposited material and substrate at this landfill has slipped that endangers the local road and "Kusak" stream at the landfill foot. That is why this landslide needs to be rehabilitated.
The deposits of Bor and Cukaru Peki are important contributors to the Apuseni–Banat–Timok–Srednogorie (ABTS) belt’s metallogenic endowment. We use decision tree and random forest algorithms applied ...to zircon geochemistry data from Bor, Cukaru Peki and a selection of other localities within the ABTS. The resulting predictions, supported by high scores on the test set predictions for the random forest algorithm, suggest that it is possible to fingerprint the studied deposits and localities from the ABTS belt based on zircon geochemistry. These results take into account the multivariate geochemical patterns and can be used in combination with a widely accepted Eu anomaly indicator or assist in finding more subtle geochemical differences for systems where applying a single cut-off value does not result in a good separation between barren and mineralized rocks.
Čukaru Peki is a recently discovered copper-gold deposit in the Bor metallogenic zone in east Serbia. Three types of mineralization can be distinguished in this ore deposit: porphyry, ...high-sulphidation, and transitional epithermal type. This research was focused on fluid inclusion analysis of genetically different veins from the porphyry and the transitional zones of Čukaru Peki with an aim of better understanding the fluid evolution and mineralization processes in this system. Seven types of veins were identified in the porphyry zone of Čukaru Peki and four of these veins contained transparent minerals which were suitable for fluid inclusion analysis. Eight types of inclusion assemblages were distinguished in these veins: type 1 – primary inclusions with homogenization temperatures above 550°C and high salinity, type 2a- scattered polyphase inclusions two salt crystals, type 2b-polyphase inclusions with two salt crystals in crystal growth zones, type 3- brine inclusions with one salt crystal in crystal growth zones, type 4- vapour-rich inclusions, type 5- primary inclusions in anhydrite, and types 6 and 7- secondary low-temperature inclusions This research suggests that saline fluids (30-40% wt.% NaCl eq.) were the most important ones for the formation of porphyry-type mineralization and that the mineralization was formed at temperatures between 350 and 450°C and pressures between 100 and 500 bars. The epithermal stage was characterized by cooler low-salinity fluids with temperatures between 150-350°C, and salinity between 0 and 7 wt.% NaCl eq.
Nadine Labaki, Lübnan’ın yetiştirdiği önemli yönetmenlerden birisidir. Eğitimini Lübnan’da tamamlaması ve filmlerini burada yapması, onu diğer Lübnanlı ve Ortadoğulu yönetmenlerden ayırmaktadır. ...Labaki’nin filmlerindeki kadın temsilinin incelenmesi, kadın sorunlarının genelde Ortadoğu özelde ise Lübnan sinemasında nasıl işlendiğinin ortaya konulması açısından önemli veriler sunar. Bu çalışmada Labaki’nin çektiği üç uzun metraj film olan Karamel (2007), Peki Şimdi Nereye? ve Kefernahum (2018) filmlerinde kadınların ve kadın sorunlarının nasıl temsil edildiği incelenmiştir. Yapılan analizler neticesinde incelenen filmlerin, toplumsal cinsiyet rol kalıplarını ve ataerkil ahlaki normları onayan bir anlatı yapısına sahip olması nedeniyle ana akım sinemaya benzer özellikler taşımakla birlikte; aktif, mücadeleci ve çözümler üreten kadın karakterlere yer vererek ana akım sinema filmlerinden farklılaştığı sonucuna ulaşılmıştır. İncelenen filmlerdeki kadınların genellikle güçlü karakterler olduğu ve çoğu zaman diğer kadınlarla dayanışma içerisinde, birlikte hareket ederek başarıya ulaştıkları; bunun mümkün görünmediği durumlarda kaderlerine razı olmadıkları ve mücadeleyi sürdürdükleri, erkek egemenliğine boyun eğen pasif kadın karakterlerin ise genellikle kaybeden taraf olarak konumlandırıldığı tespit edilmiştir. Ayrıca filmler boyunca ele alınan kadın sorunlarının ekonomik nedenleri üzerinde durulmadığı; sorunların bireyselleştirilerek kolay çözülebilir hale getirildiği belirlenmiştir.
Nadine Labaki is one of the most significant directors raised by Lebanon. She is distinguished from other Middle Eastern and Lebanese directors because she completed her education in Lebanon and made her films there. Analyzing female representation in Labaki’s films reveals important data in terms of explaining how women’s problems are handled in the Middle East in general and in Lebanese cinema in particular. In this study, how women and issues of women are represented in Labaki’s three full-length films, Caramel (2007), Where Do We Go Now? (2011), and Capernaum (2018) are examined. As a result of the analyses, it is concluded that although the films have similar features with mainstream cinema in that they approve gender role patterns and patriarchal moral codes, they differ from mainstream cinema films in terms of placing emphasis on active, combative, problem-solver female characters. It is determined that the women in the analyzed films are generally strong characters and they often succeed in solidarity with other women by acting together; in cases where this is not possible, they do not accept their destiny, and they struggle; passive female characters who are submissive to male domination are generally positioned as the losing side. In addition, it is determined that the economic causes of women’s problems handled throughout the films are not emphasized, and the problems are made easy to solve by individualizing them.
Čukaru Peki is a recently discovered porphyry- high-sulfidation Cu-Au deposit located 5km south of the mining town of Bor in east Serbia. Three styles of mineralization are distinguished in the ...Čukaru Peki system: a high-sulfidation type with massive sulfides (named the Upper zone), a porphyry type (named the Lower zone) and a transition type (between porphyries and massive sulfides). This study investigates the concentration and distribution of trace elements in pyrite from these three mineralization zones of Čukaru Peki. The high-sulfidation pyrite contains elevated concentrations of V, Mn, Ni, Cu, As, Mo, Ag, Cd, In, Sn, Sb, Au, Hg, Tl, Pb and Bi, compared to pyrite from the porphyry zone. The porphyry zone pyrite contains elevated concentrations of Co and Se. The sample from the transition zone contains concentrations between the two other zones, with the exception of the relative enrichment of Co and Ag. This research also aims to separate different stages of ore deposition. The porphyry stage contains several types of veins: quartz A veins, quartz B veins, pyrite D veins, magnetite veins, purple anhydrite veins, sulfide veins and orange anhydrite veins. The high sulfidation stage also formed in several stages: pyrite1, pyrite-enargite veins, pyrite-covellite veins, pyrite2 veins and calcite-anhydrite veins. There are distinct differences between various vein generations found within each zone, notable examples are the enrichment of Se in quartz B veins pyrite and Cu in sulfide veins, compared to other veins from porphyry zone veins and the enrichment of several trace elements (Cu, Mo, Ag, Cd, In, Sn, Sb, Au, Hg, Tl, Pb and Bi) in pyrite from the Py-cov veins in comparison to the other high-sulfidation veins. The trace element data also indicates a change in fluid compositions; the earlier fluids responsible for the porphyry zone mineralization showing a slightly more magmatic fluid signature (higher Co/Sb and Se/As values) and the later high-sulfidation fluids bearing a more typical epithermal trace element signature, which indicates cooling and diluting of fluids. Some of the porphyry zone pyrite crystals (from B-type veins and Purple anhydrite-veins) contain elevated concentrations of elements attributed to the high-sulfidation zone (e.g. Cu, Ag, Cd, In, Sn, Pb and Bi), which suggests that these veins were affected by later high-sulfidation fluids.
