Öğe Age and gender related changes in bronchial tree: a morphometric study with multidedector CT(VERDUCI PUBLISHER, 2016) Ulusoy, M.; Uysal, I. I.; Kivrak, A. S.; Ozbek, S.; Karabulut, A. K.; Paksoy, Y.; Unver Dogan, N.OBJECTIVE: The aims of this study are the identification of differences in the diameter, length, area and branching angles of the trachea and bronchi with gender and age, and the identification of trachea types by using MDCT images. PATIENTS AND METHODS: The thoracic MDCT images of 253 patients (0-74 years old, 142 male and 111 female) were evaluated. Tracheal diameter, tracheal cross-sectional area, diameter and length of bronchi, and several angles of the bronchial tree [e.g. subcarinal angles (SCA), interbronchial angles (IBA)] were measured. RESULTS: Average anteroposterior and transverse diameter of the trachea in adult patients were measured as 15.8 +/- 2.9 mm and 17.5 +/- 3.7 mm respectively. Average tracheal cross-sectional areas in adult patients were calculated as 160.7 +/- 41.3 mm(2) in females and as 275.7 +/- 57.3 mm(2) in males. Four types of trachea were identified as circular (68% in adults, 73% in children), oval (13%, 15%), rectangular (11%, 5%) and horseshoe shaped (8%, 7%). The average right and left SCA were calculated as 34.5 degrees +/- 8.1 degrees and 38.1 degrees +/- 8.9 degrees respectively. The average right and left IBA were calculated as 32.4 degrees +/- 7.7 degrees and 35.2 degrees +/- 8.1 degrees respectively. CONCLUSIONS: The findings of this study may be helpful during bronchoscopy and tube and stent application procedures. MDCT seems to be a convenient technique for the evaluation of the bronchial tree.Öğe Different igneous masonry blocks and salt crystal weathering rates in the architecture of historical city of Konya(PERGAMON-ELSEVIER SCIENCE LTD, 2007) Ulusoy, M.The damaging effects of salt crystal growth on the ancient igneous masonry blocks in Konya region have been investigated. A systematic mineralogical, petrographical and chemical examination of weathered masonry blocks and crusts was performed, both in situ and in the lab on samples received from different locations of Konya. Basically, sodium sulphate and magnesium sulphate soundness tests were carried out to determine the salt crystal weathering rates for the nine different igneous masonry blocks. The tests subject samples to immersion in sodium sulphate and magnesium sulphate solutions and oven drying, repeating this process through at least 15 cycles. After these testing cycles, weight loss of the masonry samples was measured and the durability of each sample was assessed by the percentage of weight lost. The strength reduction of each sample was also experimentally determined. (c) 2005 Elsevier Ltd.

A.; Oral, M.Refunctioning is a widely used method for protecting historical structures. However, throughout architectural education, functioning historical structures and producing new designs in terms of historical pattern do not attract great attention within the framework of design studios. It is a fact that in such schools that abovementioned items are more popular, the connection between protection oriented studio and design studio is pretty weak. In this study refunctioning was discussed as a design studio topic in relation to the old girls. teacher training school and its immediate surroundings. The primary objective of this design studio is to increase architecture students. awareness in terms of visual and perceptual levels of project designs in historical patterns. Within the context of this manuscript, the experiences gained during design studio process were transferred and discussed.
