Integrated usage of geophysical prospection techniques in Höyük (tepe, tell)-type archaeological settlements

The integrated use of geophysical methods has developed rapidly in the last fifteen years in archaeological prospection (Brizzolari et al., 1992; Gaffney et al., 2004; Drahor, 2006; Casana et al., 2008). The combined application of different geophysical techniques supplies useful information about buried archaeological contexts, particularly höyük(tell, tepe)-type archaeological settlements. The aim of such studies is to help archaeologists conduct fast, effective and economical excavations b..

Some quality properties of çökelek cheeses containing black cumin and dill dried at different temperatures

Kurutma en eski gıda maddelerini muhafaza etme yöntemlerinden biridir. Gıda ve tarım ürünlerini muhafaza etmek için yüzyıllardır yaygın olarak kullanılmaktadır. Kurutma prosesi süt endüstrinde de uygulanmaktadır. Dereotu ve çörek otu şifalı bitkilerdir. Bu çalışmada çökelek peynirine kurutulmuş dereotu ve çörek otu ilave edildikten sonra 3 farklı hava sıcaklığında (40, 50 ve 60°C) tepsili kurutucuda kurutulmuşlardır. Kurutulan örnekler 60 gün süreyle 4±1°C’de depolanmış ve depolama süresince (1. 30. ve 60. günlerde) bazı kimyasal özellikleri, duyusal özellikleri, tekstürel özellikleri, toplam fenolik madde içeriği ve antioksidan aktiviteleri belirlenmiştir. Kurutulan peynirlerin kuru madde ve kuru madde üzerinden %yağ içeriklerini örnek ve sıcaklık farklılıkları önemli düzeyde etkilememiştir (p>0,05). Örneklerin olgunlaşma derecesi depolama süresince artış göstermiştir. Çörek otu ilave edilen peynirlerin antioksidan aktivitesi değerleri diğer örneklere göre daha yüksek belirlenmiştir. Depolama süresince sertlik, çiğnenebilirlik ve sakızımsılık değerlerinin arttığı tespit edilmiştir. Depolama süresince toplam bakteri sayımı miktarı 5,00 log kob/g ile 6,35 log kob/g, maya küf sayımı miktarı 0,50 log kob/g ile 2,85 log kob/g arasında değiştiği görülmüştür. Depolamanın 1. ve 60. günü 50°C’de kurutulmuş ve dereotu ilaveli peynirlerin genel beğeni puanları daha yüksek tespit edilmiştir. Farklı sıcaklıklarda kurutulan çökelek peynirleri çoğunlukla panelistler tarafından beğenilmiştir.Drying is considered as the oldest food preservation technique and has been widely used for centuries to preserve different food and agricultural products. This process is applied in dairy industry. Dill and black cumin are medicinal plants. In this study, dried dill and black cumin were added to çökelek cheese and dried in in a tray dryer at three different drying air temperatures (40, 50 and 60°C). Cheese samples were stored at 4±1°C for 60 days and some chemical properties, sensory properties, texturel properties, total phenolic content and antioxidant activity value of dried samples were evaluated during the storage time (on the 1st, 30th and 60th days). The dry matter content and fat content in dry matter of dried cheese were not statistically significantly (p>0.05) affected by different temperatures and samples. The ripening degree of the samples showed on increase during storage period. The antioxidant activity value of cheese by adding black cumin was found to be higher than the other cheeses. It was determined that the hardness, chewiness and gumminess values increased throught storage period. Total viable counts varied between 5.00 log cfu/g and 6.35 log cfu/g, yeast and mould counts varied between 0.50 log cfu/g and 2.85 log cfu/g during storage period. On the 1st and 60th day of storage period, the general appreciation score of the dried cheese produced with dill was higher than of the other samples at 50°C dry temperature. The çökelek cheeses dried at different temperatures were mostly appreciated by the panelists

Biochemical and Molecular Characterization of Strontium-resistant Environmental Isolates of Pseudomonas fluorescens and Sphingomonas paucimobilis

Icgen, Bulent/0000-0001-8114-4230WOS: 000322301100001Strontium resistance was investigated in strains isolated from the river Kzlrmak which has been affected by industrial and agricultural heavy metal pollution from the surrounding facilities and domestic effluents from the city Krkkale, Turkey. Strontium-resistant isolates with a minimal inhibitory concentration of 2000mg L-1 were isolated and identified as Pseudomonas fluorescens and Sphingomonas paucimobilis. Both isolates were shown to be resistant to other heavy metals like aluminum, lithium, barium, nickel and resistance to the antibiotics like aztreonam and pefloxacin. Plasmid DNA analysis, transformation and curing results revealed that the strontium resistance ability of both isolates was chromosome-encoded. Outer membrane and total protein isolation results descriptively showed that not only membrane porins but also other proteins were effective in the strontium resistance in Pseudomonas fluorescens and Sphingomonas paucimobilis.Kirikkale University Research FundKirikkale UniversityThis research project has been supported by Kirikkale University Research Fund

Surface Water-Borne Multidrug and Heavy Metal-Resistant Staphylococcus Isolates Characterized by 16S rDNA Sequencing

Icgen, Bulent/0000-0001-8114-4230WOS: 000327122200016PubMed: 24068465Four Staphylococcus isolates having both multidrug- and multimetal-resistant ability were isolated from surface water. Further identification of the isolates was obtained through biochemical tests and 16S rDNA gene sequencing. One methicillin-resistant and two methicilin-sensitive isolates were determined as Staphylococcus aureus. The other isolate was identified as Staphylococcus warneri. The antibiotic and heavy metal resistance profiles of the Staphylococcus isolates were determined by using 26 antibiotics and 17 heavy metals. S. aureus isolates displayed resistance to most of the beta-lactam antibiotics tested. All Staphylococcus isolates were resistant to heavy metals including silver, lithium, and barium. Due to a possible health risk of these pathogenic bacteria, a need exists for an accurate assessment of their acquired resistance to multiple drugs and metals

Infusion versus bolus injection of Tc-99m tetrofosmin in the identification of viable myocardium

In this report, a patient with 100% RCA stenosis and prominent collaterals, in which Tl-201 rest/redistribution and Tc-99m tetrofosmin infusion imaging findings were compatible with viable myocardium in contrast to Tc-99m tetrofosmin bolus imaging is presented, Viability was confirmed with improvement of wall motion and perfusion 3 months after revascularization, Infusion of Tc-99m tetrofosmin rather than a bolus injection may be a more reliable technique in the identification of severely ischemic but viable myocardium
