3D Architectural Surveying of Diyarbakir Wall's Ulu Beden Tower with Terrestrial Laser Scanner

AbstractTurkey is one of the countries hosting many historical monuments. Many different cultures left rich traces of civilization in Anatolia. Keeping historical artifacts and documentation of these works is very important for the protection of this heritage. The technological progress changed the methods of surveying applications used nowadays. The changes in the methods of surveying applications reflected in the building survey applications too. The traditional surveying methods were replaced by digital photogrammetry and then by laser scanning methods. This work is contains the building survey of the Ulu Beden tower which is a part of Diyarbakir walls. Diyarbakir is a province in southeastern Turkey and in the past, it was home for many civilizations. Hittites, Persia, Macedonian and Seleucid Greeks, Rome, Byzantium, Arabs, Seljuk Empire, Mongol Empire and Ottoman Empire are among these civilizations leaving the traces in Diyarbakir. Diyarbakir wall is the second longest wall after the Great Wall of China. Hundreds of years after the construction of the walls, it is necessary to protect and restore it due to the corruption and demolition over time. In total, 45 stations were built for an architectural survey with laser scanner and the gathered point cloud data were combined together within computer environment to obtain a 3D model of the structure

INVESTIGATION OF THE COMPATIBILITY OF FASILLAR AND EFLATUNPINAR HITΤITE MONUMENTS WITH CLOSE-RANGE PHOTOGRAMMETRIC TECHNIQUE

There are two Hittite monuments in Konya whose names are Eflatunpınar and Fasıllar. Eflatunpınar is located approximately 25 km at the North of Beysehir town within Konya province in Turkey. Eflatunpınar monument is belonging to Hittite Empire Age, was known since XIX century. It is an open air temple of Hittite, 6.60 m wide and 7 m high, was built with large block stones. The second one known as Fasıllar Hittite monument lies on a hillside next to the Fasıllar village which is 16 km east of Beysehir town and it is a high relief monument which is made of basalt rock. It is commonly accepted that these two monuments had never been completely finished. J. Mellaart have suggested that Fasıllar monument was not in-situ position, it was moved from Eflatunpınar to Fasıllar village by the local people for decoration purposes. This means that ac-cording to J. Mellaart, Fasıllar monument is the part of Eflatunpınar monument. The objective of this study is to investigate whether Fasıllar monument was built for placing on the top of Eflatunpınar monument which is firstly raised a subject by J. Mellaart. For this purpose, three-dimensional (3D) digital model was created for each monument by close-range photogrammetric technique. By the help of the 3D digital models of these monuments, the unity between the monuments were investigated as an engineering approach

Burnout treatment on plaster mould produced with binder jetting technology: effect of process parameters and geometrical complexity

Binder jetting (BJ) is an additive manufacturing technology that realizes mineral or metallic parts without support material and avoiding critical issues due to thermal phenomena. Because of these benefits, this technology is suitable for rapid tooling applications, as well as for casting process to produce complex moulds made for instance in plaster and organic compound as binder. Regarding the latter application, it is worth noting that chemical reactions can occur when the mould is in contact with molten metal, leading to the formation of gas and therefore porosity in the cast part. To limit this phenomenon, a burnout cycle is usually required before pouring the molten metal. In this research, the burnout temperature and time were investigated, as well as the pre-heating mould temperature before metal pouring in case of simple and complex part geometries. Three different levels of each studied parameters were tested, and the results were analysed in terms of casting defects. Results highlight that a burnout treatment performed at 250 °C for 6 h guarantees the best compromise in terms of casting soundness

Morphometric evaluation of chinchillas (Chinchilla lanigera) femur with different modelling techniques [Chinchilla (Chinchilla lanigera) femur’unun farklı modelleme teknikleri ile morfometrik değerlendirilmesi]

Together with technological developments, different methods in anatomic and morphometric studies have been started to be used. In fact, in this study, more than one method was used and the reliability of these methods was presented. This study was performed in the aim of getting 3D model with three dimensional (3D) reconstruction and photogrammetric methods obtained from multidetector computerized tomography (MDCT) images of femur of chinchilla by mimics program, comparing the data of both methods and presenting whether there was a difference between genders as well as left and right sides. For this purpose, 6 chinchillas of both sexes were used. First of all, MDCT images of animals were taken under general anaesthesia and 3D reconstruction was obtained after transferring the data to personal computer as DICOM format. After taking MDCT images, the femurs of the animals killed by the conventional methods were cleaned of muscle and fats by boiling and their 3D models was formed by using images via photogrammetric methods. The measurements were taken from the models of two methods and volume and surface area of femur were found significant at a level of p<0.05 as a result of statistical processes. According to this, a statistically difference was not found in morphometric measurement values except volume and surface area. Moreover, while a statistical difference was not found between right and left femur of both sexes, a difference was determined between sexes and it was observed that the measurement values of females were higher than males. As a result, since 3D models obtained by both methods had almost same values, it was considered that these methods could be used in anatomic and morphometric studies. © 2016, Veteriner Fakultesi Dergisi.

Effect of frozen storage (-30 degrees C) an fatty acid composition of sardines (Sardina pilchardus W-1792)

The aim of the study presented here was to find out the effects of storage at -30 degrees C on fatty acids in fish oil, without adding antioxidants. Oils of sardines from the Sea of Marmara were extracted, analysed and stored at +4 degrees C for 4 and 8 days, and thereafter at -30 degrees C for 24 months. Fatty acid composition analyses were performed initially and after 4 and 8 days as well as after 24 months. In the case of the fatty acids C-16:0, C-20:1, C-18:3, C-22:6, C-14:0, C-16:1, and C-20:5 considerable changes with regard to their concentrations could be observed. In general, there was a decrease in minor unsaturated fatty acid (MUFA) content, and an increases in the saturated fatty acid and in some polyunsaturated fatty acid (PUFA) content

Caviar production from flathead grey mullet (Mugil cephalus, Lin. 1758) and the determination of its chemical composition and roe yield

WOS: 000174339400028The aim of this research is to determine the yield and chemical composition of the caviar produce from flathead grey mullet (Mugil cephalus, Lin.1758) in the Sufa lagoon. Acording to the results of our research 21.98% of the fish with an average live weight of 1.243.63 +/- 322.44 g and 49.11 +/- 3.83 cm length contains with roe. Salting the caviar caused a weight loss of 35%. As a result of salting, the salt content of the product was raised to 4.61% and as a result of waxing this reached a maximum of 7.04%. In all chemical composition parameters salted and waxed caviar groups had lower moisture, higher protein, fat and ash contents when compared to raw caviar
