Ulucak Höyük: Pojav lončenine v zahodni Anatoliji

It has been increasingly clear that pottery was adopted as a continuous technology during the first quarter of the 7th millennium BC in a wide region, from Upper Mesopotamia through Central Anatolia and the Lakes District region. However, the absence of pottery in the basal level at Ulucak Höyük shows the presence of a pre-ceramic sequence in western Anatolia, before c. 6600/6500 cal BC. This article discusses the earliest pottery assemblage from Ulucak (6600/6500–6200 cal BC) and compares it with the later ceramic sequences at the site. Ultimately, the functional and typological developmental sequence of Neolithic pottery at Ulucak Höyük and its temporo-spatial relations with other Neolithic sites in Anatolia will be assessed.Vse bolj je jasno, da je bilo lončarstvo kot tehnologija sprejeto neprekinjeno v prvi četrtini 7. tisočletja pr. n. št. na širokem območju od zgornje Mezopotamije do osrednje Anatolije in območja jezer. Kljub temu odsotnost lončenine v najglobljih plasteh na najdišču Ulucak Höyük kaže na obstoj predkeramične sekvence v zahodni Anatoliji, in sicer pred ok. 6600/6500 pr. n. št. V članku razpravljamo o najzgodnejšem zbiru lončenine iz Ulucaka (6600/6500–6200 pr. n. št.) in ga primerjamo s kasnejšimi sekvencami keramike na tem najdišču. Na koncu ocenjujemo funkcionalno in tipološko razvojno sekvenco neolitske lončenine na najdišču Ulucak Höyük in njeno časovno in prostorsko povezavo z drugimi neolitskimi najdišči v Anatoliji

Spatial and temporal heterogeneity in human mobility patterns in Holocene Southwest Asia and the East Mediterranean

We present a spatiotemporal picture of human genetic diversity in Anatolia, Iran, Levant, South Caucasus, and the Aegean, a broad region that experienced the earliest Neolithic transition and the emergence of complex hierarchical societies. Combining 35 new ancient shotgun genomes with 382 ancient and 23 present-day published genomes, we found that genetic diversity within each region steadily increased through the Holocene. We further observed that the inferred sources of gene flow shifted in time. In the first half of the Holocene, Southwest Asian and the East Mediterranean populations homogenized among themselves. Starting with the Bronze Age, however, regional populations diverged from each other, most likely driven by gene flow from external sources, which we term “the expanding mobility model.” Interestingly, this increase in inter-regional divergence can be captured by outgroup-f$_3$-based genetic distances, but not by the commonly used F$_{ST}$ statistic, due to the sensitivity of F$_{ST}$, but not outgroup-f$_3$, to within-population diversity. Finally, we report a temporal trend of increasing male bias in admixture events through the Holocene

Modification of ring spinning machine for producing core yarn containing elastane

Son yıllarda ülkemizde esnek üretim amaçlı, daha çok ithal teknoloji kullanılarak modernize edilen makinelerde farklı iplik tipleri üretilmeye çalışılmaktadır. Bu modernizasyonların çoğunda yurt dışı kaynaklı teknolojiler kullanıldığından, bu çalışmada konvansiyonel üretim yapan bir ring iplik eğirme makinesinin tamamen yerli olanaklarla elektronik ve tam kontrollü olarak elastan içerikli kor iplik üretmek üzere modifikasyonu anlatılmıştır. Söz konusu modernizasyon, Çukurova Üniversitesi Tekstil Mühendisliği Bolum laboratuvarında bulunan 56 iılik bir ring iplik eğirme makinesine uygulanmış ve TUBİTAK tarafından da desteklenmiştir.In recent years, different types of yarns are produced by using flexible machines which is modernized with imported technology in our country. In this study, a modification of a conventional ring spinning is explained for producing core-spun yarns which contain elastane. This modification is applied for a 56 spindles ring spinning machine which is situated in the Cukurova University Textile Engineering Department Laboratory made by using purely domestic interests. This study is supported by TUBTAK for financially
