The Importance of Chert in Central Anatolia: Lessons from the Neolithic Assemblage at Çatalhöyük, Turkey

Nazaroff A.J. | Baysal A. | Çiftçi Y.

Article | 2013 | Geoarchaeology28 ( 4 ) , pp.340 - 362

This paper is a presentation of three sources of artifact-quality chert in Central Anatolia. A previous dearth of research focused on locating and characterizing such raw material sources has incorrectly colored our view of prehistoric economic practices. To remedy this situation, we have conducted a survey of various locales within Central Anatolia to test for the presence of artifact-quality materials. We make use of Individual Attribute Analysis (IAA) and Energy Dispersive X-ray Fluorescence (EDXRF) analysis to discriminate among these materials, and suggest their use by the Neolithic occupants of Çatalhöyük through similar analy . . .ses of artifactual materials. We argue that the presence and characterization of these new sources allows us to better understand the intricacies of Neolithic practices by illustrating the ways in which the consumption of these materials was variably entwined with the exploitation of other resources, as well as embedded within social relations outside of Central Anatolia. © 2013 Wiley Periodicals, Inc.

Optimization of design and operating parameters in a pilot scale Jameson cell for slime coal cleaning

Hacifazlioglu H. | Toroglu I.

Article | 2007 | Fuel Processing Technology88 ( 7 ) , pp.731 - 736

The Jameson flotation cell has been commonly used to treat a variety of ores (lead, zinc, copper etc.), coal and industrial minerals at commercial scale since 1989. It is especially known to be highly efficient at fine and ultrafine coal recovery. However, although the Jameson cell has quite a simple structure, it may be largely inefficient if the design and operating parameters chosen are not appropriate. In this study, the design and operating parameters of a pilot scale Jameson cell were optimized to obtain a desired metallurgical performance in the slime coal flotation. The optimized design parameters are the nozzle type, the he . . .ight of the nozzle above the pulp level, the downcomer diameter and the immersion depth of the downcomer. Among the operating parameters optimized are the collector dosage, the frother dosage, the percentage of solids and the froth height. In the optimum conditions, a clean coal with an ash content of 14.90% was obtained from the sample slime having 45.30% ash with a combustible recovery of 74.20%. In addition, a new type nozzle was developed for the Jameson cell, which led to an increase of about 9% in the combustible recovery value. Crown Copyright © 2007 Daha fazlası Daha az

Resilience and Redundance: Resource Networks and the Neolithic Chert Economy at Catalhoyuk, Turkey

Nazaroff, Adam Joseph | Baysal, Adnan | Ciftci, Yahya | Prufer, Keith

Article | 2015 | EUROPEAN JOURNAL OF ARCHAEOLOGY18 ( 3 ) , pp.402 - 428

The polycentric nature of Neolithic developments in the Middle East has prompted several discussions related to the processes driving regional diversification in the emergence of agglomerate societies. Archaeologists have recognized how diverse social, environmental, and material landscapes shaped various communities, resulting in a heterogenous Neolithic world. In this paper, we use portable x-ray fluorescence analysis to determine the use of different chert resources at the site of Catalhoyuk, Turkey, and question how their consumption affected, and was affected by, different social and material practices enacted within the commun . . .ity. We adopt a network perspective to examine the range of behaviours that consumed particular resources, and trace how alterations in these networks impacted the social fabric of Catalhoyuk. Ultimately, we conclude that different investments involved in the consumption of each resource either promoted or restricted their use through time. A more complete picture of Neolithic life, we suggest, takes note of the varied relationships that communities developed with nearby social and environmental landscapes, including nuances in the ways in which resources were incorporated into different facets of each community Daha fazlası Daha az

Article | 2016 | TURK GOGUS KALP DAMAR CERRAHISI DERGISI-TURKISH JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY24 ( 3 ) , pp.561 - 564

Factor XII deficiency is an important hematological problem which is characterized by isolated prolongation of the activated partial thromboplastin time and presents with thrombosis and thromboembolism tendency rather than expected bleeding diathesis in clinical practice. A 55-year-old male patient who was scheduled for aortic coronary bypass graft surgery had elevated activated partial thromboplastin time (109.4 sec) as a laboratory finding. The patient was diagnosed with factor XII deficiency and operated in our clinic. No thromboembolic event was seen during follow-up. The patient was discharged in the seventh postoperative day u . . .neventfully. Herein, we highlight the importance of this disease due to its rare occurrence and present our treatment strategy applied Daha fazlası Daha az

Bu çalışmamızda prostat kanserinde PSA’ya ek olarak TNF-? ve IL-8’in tanısal değerinin olup olmadığının araştırılmasını amaçladık. Bu çalışmaya Ocak ve Aralık 2005 tarihleri arasında ZKÜ Tıp Fakültesi üroloji polikliniğinde PSA yüksekliği nedeniyle prostat biyopsisi planlanan toplam 37 hasta alındı. Hastaların TNF-? ve IL-8 düzeyleri her hasta için iki adet 100 µL serum örneği alınarak ve Immulite® IL8 ve Immulite® TNF-? kitleri kullanılarak pg/ml biriminde ölçüm yapıldı. BPH ve Prostat kanserli grupta TNF-? ve IL8 değerleri karşılaştırıldı. Ayrıca kanserli grupta Gleason skoru ile bu ölçütler arasındaki korelasyon incelendi. Prosta . . .t kanseri olan grupta (n=20) IL-8 düzeyleri 5.0 pg/ml ile 46.2 pg/ml arasında ve ortalama 12.1 pg/ml, TNF-? düzeyleri ise 4.0 ila 10 pg/ml arasında ve ortalama 5.64 pg/mL olarak saptandı. BPH grubunda (n=17) ise bu düzeyler IL-8 için 5.0 ila 27.4 pg/ml arasında ve ortalama 9.094 pg/ml, TNF-? düzeyleri ise 4.0 ila 9.0 pg/ml arasında ve ortalama 5.46 pg/ml olarak tespit edildi (p>0.05). Gleason skoru ve bu ölçütler arasında istatistiksel olarak korelasyon saptanmadı. Çalışmamızdan BPH’lı ve prostat kanserli hastaların serum TNF-? ve IL-8 düzeyleri arasında istatistiksel açıdan anlamlı farklılık saptanmamıştır. TNF-? ve IL-8’in prostat kanserli hastalarda tanısal değerinin olmadığı düşünülse de, TNF-? ve IL-8’in prostat kanseri patogenezindeki rolleri ve prostat kanseri seyrindeki belirleyici yerleri farklı evredeki hasta grupları ve daha geniş serilerde araştırılmalıdır. Introduction: In this study, we aimed to evaluate TNF-α and IL-8 levels in patient with prostate cancer as diagnostic tools additional to PSA. Materials and Methods: In this current study, we included a total of 37 patients who were planned to undergo prostate biopsies in Department of Urology of Zonguldak Karaelmas University due to having high PSA levels between January and December 2005. Two samples of serum each containing 100 µL plasma were collected from each patient in order to measure TNF-α and IL-8 levels by using Immulite® IL8 and Immulite® TNF-α immunometric assays and results were given in pg/mL unit. TNF-α and IL-8 levels were compared in groups of BPH and prostate cancer. Additionally, Gleason score and those parameters were compared within prostate cancer group. Results: IL-8 levels were between 5.0 pg/mL to 46.2 pg/ml and mean IL-8 level was 12.1 pg/ml; TNF-α levels were between 4.0 pg/ml to 10 pg/mL and mean TNF-α level was 5.64 pg/ml in prostate cancer group (n=20). IL-8 levels were between 5.0 pg/ml to 27.4 pg/ml and mean IL-8 level was 9.094 pg/ml; TNF-α levels were between 4.0 pg/ml to 9 pg/mL and mean TNF-α level was 5.46 pg/ml in BPH group (n = 17) (p>0.05). There was no statistical corelation detected between Gleason score and those parameters. Conclusion: There were not any significant statistical difference in TNF-α and IL-8 levels between patients with BPH and prostate cancer. IL-8 and TNF-α do not seem to diagnostic value in patients with prostate cancer. However, the role of TNF-α and IL-8 in prostate cancer etiology and their roles in diagnosing prostate cancer and prognosis of prostate cancer should be investigated in larger series Daha fazlası Daha az

Preoperative Evaluation of Lymph Node Metastases in Patients with Gastric Cancer: An Analysis of Imaging Methods

Günay, Yusuf | Çağlar, Emrah | Korkmaz, Esin | Erdemir, Rabiye Uslu | Taşdöven, İlhan | Kozan, Ramazan

Article | 2018 | ACTA ONCOLOGICA TURCICA51 ( 3 ) , pp.276 - 282

INTRODUCTION: Preoperative evaluation is necessary for the surgical treatment of gastric cancer (GC). Nonetheless, there is no single best diagnostic modality to predict lymph node metastases prior to surgery. The aim of this study was to analyze of the diagnostic utility of positron emission tomography-computed tomography (PET-CT) and CT for the preoperative evaluation of lymph node (LN) metastases in GC. METHODS: Eighty seven patients with a history of GC, who underwent gastrectomy and D2 LN dissection were investigated. Imaging test results and pathology reports were collected from the patients’ charts. RESULTS: There was no stat . . .istical differences between PET/CT and CT scans in regard to predicting LN metastases in GC patients (p>0.05). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of PET/CT scans in predicting LN metastases were 55.56%, 54.55%, 55.26%, 75%, and 33.3%, respectively, versus 60.47%, 57.69%, 59.42%, 70.27%, and 46.88% for CT scans, respectively. However, combined PET/CT and CT showed better outcomes and specificity with a PPV of 80% and 88.9%, respectively. No patients or tumor factors were found to increase the accuracy of LN metastasis prediction using either PET/CT or CT scans. DISCUSSION AND CONCLUSION: The combination of CT and PET/CT scans increases the specificity and PPV. This increases the prediction accuracy of LN metastasis in GC patients compared to the use of each type of imaging modality alone.
