Opis:
The static criterion that the amplitude of the principal peak of the liquid structure factor has a constant value along the freezing line and the onset of freezing are studied from the structure factors and the static dielectric functions of halide salts interacting via the effective pair potentials through the hypernetted-chain approximation. It is observed that the criterion above is restricted to the effective charge difference. The critical value of plasma parameter at freezing is affected by the mobility and number concentration of anions and cations. The distribution of the value of the static dielectric function closest to the wave number axis in the negative region is also determined by the charge difference and the ordering of ions and related to the onset of freezing.

Opis:
In this study, an artificial neural network application was performed to tell if 18 plates of the same material in different shapes and sizes were cracked or not. The cracks in the cracked plates were of different depth and sizes and were non-identical deformations. This ANN model was developed to detect whether the plates under test are cracked or not, when four plates have been selected randomly from among a total of 18 ones. The ANN model used in the study is a model uniquely tailored for this study, but it can be applied to all systems by changing the weight values and without changing the architecture of the model. The developed model was tested using experimental data conducted with 18 plates and the results obtained mainly correspond to this particular case. But the algorithm can be easily generalized for an arbitrary number of items.

Opis:
In this study, the possibility of enhancing heat insulation performance of hollow bricks by filling the cavities with perlite is investigated. A conjugate heat transfer by conduction, convection and radiation in different hollow bricks are analyzed numerically to assess their thermal performance. Calculations are performed for three scenarios for each type of hollow brick: (i) cavities are filled with air, (ii) half of the cavities are filled with perlite while the other half is filled with air, (iii) all cavities are filled with perlite. The benefit of filling cavities with perlite is justified quantitatively for each investigated hollow brick type. It is concluded that the enhancement in insulation performance can be up to 15.6% and 27.5% for half-perlite and full-perlite cases, respectively, depending on the brick type.

The $K_{β} // K_{α}$ X-ray intensity ratios of Co, Ni, Cu and Zn in metalophthalocyanines complexes have been studied. Co, Ni, Cu and Zn elements have been excited by using 59.5 keV photons emitted by 50 mCi $\text{}^{241}Am$ radioactive source. K X-rays emitted by samples have been counted by a Si(Li) detector with resolution 0.16 keV at 5.9 keV. We have found that $K_{β} // K_{α}$ X-ray intensity ratios of Co, Ni, Zn, and Cu complexes have changed depending on chemical structures of Co, Ni, Zn and Cu. The measured values have been compared with the theoretical predictions and experimental values of pure elements.

Opis:
Iodine is an essential element for the production of thyroid hormones. In recent years, it has been suggested that excessive consumption of iodine may play a role in the pathogenesis of papillary thyroid cancer (PTC). In addition, studies have suggested that high iodine consumption is an important risk factor for the formation of a BRAF mutation in the thyroid gland. A prospectively designed study included 132 cases scheduled for thyroidectomy for various reasons. Urine iodine levels of all patients were examined before the operation. The iodine excretion levels of the patients were grouped according to the median urinary iodine concentration determined in community screenings (those with <100 µg L-1 low iodine excretion, those with 100-199 µg L-1 normal iodine excretion, those with 200-299 µg L-1 high iodine excretion). Patients were divided into 3 groups according to the post-operative pathology results. As a result of thyroid histopathology, benign (n: 44), PTC (n: 88) (BRAF (+): 44 and BRAF (-): 44) cases were included in the study. BRAF mutations in patients diagnosed with PTC were evaluated using the “Real Time PCR Melting Curve Analyzer” method. The relationship between urinary iodine excretion levels and clinical, histopathological and BRAF positivity was examined. In our study, no difference was found in urinary iodine excretion between patients with and without PTC. Hashimoto’s thyroiditis was observed more frequently in patients with PTC (p=0.023). In addition, Hashimoto’s thyroiditis was statistically more frequently detected in the BRAF (-) group compared to the BRAF (+) and control group (p=0.034). Despite studies suggesting that high iodine consumption is important in PTC pathogenesis, we did not find a relationship between the mutation and iodine consumption, which plays an important role in the development of PTC.

Opis:
Poly(2-hydroxyethyl methacrylate)-co-poly(4-vinyl pyridine) and poly(HEMA)-co-poly-(4-VP) copolymers were synthesized by free radical polymerization. K₂S₂O₈ was used as an initiator. Chain lengths of the copolymer was changed by varying the monomer/initiator ratio. These polymers have molarites of 2.6 and 2.1 respectively and are called COP2 and COP4. The samples were exposed to gamma rays at room temperature. After irradiation, the EPR spectra of COP2 and COP4 were recorded between 120 K and 450 K. From the temperature dependence of the line intensity, it was concluded that unpaired spin concentration in the irradiated samples has been changing with temperature. A theoretical study, presented in this report, was aimed to test success of the machine learning methods and to select the best learning method.

Opis:
In this paper, Turkey's comparative advantage and competitiveness in the textile and clothing industries are analysed by using Balassa's revealed comparative advantage index and Vollrath's indices of competitive advantage for the period of 1988-2008 in the enlarged EU market. The results revealed that Turkey has overall a strong comparative advantage and competitiveness in textile and clothing in the EU market. All competitiveness indices for the years 2005-2008 showed an increasing trend for the textile industry and a decreasing trend for clothing. The decrease in the competitiveness of clothing was observed more intensively in the enlarged EU market compared to that of the EU12. These findings can be thus interpreted: the Turkish textile industry responded well to the elimination of quotas, while the clothing sector has been more vulnerable to the inclusion of low-cost labour countries in the market since 2005.
Artykuł przedstawia analizę przewagi komparatywnej i konkurencyjności tureckiego przemysłu tekstylnego i odzieżowego przeprowadzoną w oparciu o indeksy Balassy i Vollrath'a za okres 1988 - 2008. Wykazano, że pozycja Turcji była zdecydowanie korzystna. W okresie 2005 - 2008 stwierdzono wzrost współczynników dla przemysłu tekstylnego, natomiast spadek dla przemysłu odzieżowego. Spadek konkurencyjności był intensywniejszy dla powiększonego rynku EU w porównaniu do EU 12. Pozycja tureckiego przemysłu tekstylnego była bardziej stabilna, podczas gdy przemysł odzieżowy okazał się bardziej podatny na przyłączenie nowych członków UE.

Opis:
In this study, the comparative advantage of four countries in the world: Bangladesh, China, Germany and Turkey is analysed with respect to the US and the EU-15 textiles and cloth-ing markets by employing Balassa’s revealed comparative advantage (RCA) index for the period 2000-2010. This country selection was made because all these countries rank in the top ten textile and clothing exporters in the world and they represent economies from four different income levels. The results have revealed that Bangladesh, China and Turkey have a strong comparative advantage in both the textile and clothing markets of the world, the US and the EU-15, while Germany has no significant comparative advantage in any of these markets. The findings show that the Bangladesh clothing industry has a substantially higher comparative advantage in all three markets compared to the other countries. It has also been found that Turkish textiles show the strongest comparative advantage in all three markets, whereas the comparative advantage of Chinese textiles indicates a slightly increasing trend in all aforementioned markets.
W pracy przeanalizowano przewagę komparatywną czterech krajów na tekstylno-odzieżowych rynkach światowych, Stanów Zjednoczonych oraz EU-15, stosując wskaźnik przewagi komparatywnej typu Balassy (RCA) dla okresu 2000–2010. Wybrane kraje znajdują się w rankingu dziesięciu największych eksporterów wyrobów włókienniczych i odzieżowych na świecie i równocześnie reprezentują kraje o czterech różnych poziomach dochodu. Wykazano, że Bangladesz, Chiny i Turcja maja silną przewagę komparatywną na tekstylnych i odzieżowych rynkach światowych, Stanów Zjednoczonych i EU-15, Niemcy natomiast nie wykazują znaczącej przewagi komparatywnej na żadnym z wymienionych rynków. Wykazano również, że przemysł odzieżowy Bangladeszu ma znacznie wyższą przewagę komparatywną na wszystkich trzech rynkach w porównaniu z pozostałymi krajami. Przemysł tekstylny Turcji również wykazuje najsilniejszą przewagę komparatywną na wszystkich trzech rynkach, podczas gdy przewaga komparatywna przemysły tekstylnego Chin wykazuje nieznaczną tendencję wzrostową.

Opis:
In the present work, Cu and Ni nanofluids were synthesized using the pulsed wire evaporation (PWE) method in the different aqueous medias, namely (ethanol and ethylene glycol), and the effects of the aqueous media on the dispersion state, stability, and particle size of nanoparticles were studied. The size and morphology of synthesized nano-particles were investigated by transmission electron microscopy (TEM). Also, the dispersion stability of the nanofluids was evaluated by turbiscan analysis. The TEM results showed that the nano-particles were spherical in shape, and the average particle size was below 100 nm. The average particle size of the Cu nano-particles was smaller than that of Ni, which was attributed to a difference in the specific sublimation energy of the elements. Moreover, ethylene glycol (EG) exhibited higher suspension stability than ethanol. Finally, the dispersion stability of Cu@EG displayed the highest value due to lower particle size and greater viscosity.

Opis:
The Metropolitan Municipality of Izmir (Turkey) designated a steeply inclined area for the construction of buildings to house the participants of the Izmir University Olympic Games. Before the construction activities could start, engineering geological and geotechnical investigations had to be carried out in order to establish which zones in the area were suitable for safe constructions. Seismic studies, borings and laboratory tests yielded the data, which were used for preparing five hazard maps in a GIS environment. The construction activities based on the results of this complex investigation appeared successful. The engineering geological investigations included geotechnical measurements on core samples obtained from the boreholes (core drilling) and laboratory testing. The rock-quality designation (RQD%) values of the rock units were determined and used in the rock-mass classification (rock-mass rating method) as an in-put parameter and in the calculation of the bearing capacity of the various rock units. Geophysical surveys were carried out to determine the seismic velocity of the rocks at the site. A short overview is provided of the main problems that had to be dealt with, and of the successive steps taken to solve the engineering-geological problems. Determination of these problems is necessary for adequate land-use planning and construction activities.

Ships have an important role in among the factors causing marine pollution. Marine pollution by ships damages sea life, which effects human health indirectly, in addition it restricts usage of sea for different purposes. Increasing comprehensive and compelling liabilities related with environmental components and subjects day by day are expected results for environmental science and engineering applications according to 60% of our responsibilities of European Union Integration development. In today’s’ world, where global warming is an issue of high priority and makes us feel its impacts in our lives, leaving a livable world to the next generations is now a primary goal for all. Determination of marine pollution caused by ship operations issue is a multiple criteria decision-making (MCDM) problem, and requires MCDM methods to solve it. Therefore, the role of ship factor in maritime pollution and the possible reasons of this argument can be quantitatively evaluated based on expert knowledge and MCDM methodology. To investigate what makes to reduce the first “caused by ship operations " in marine pollution, the decision-making trial and evaluation laboratory (DEMATEL) method approach was applied in this study.

The aim of this study was to evaluate the efficacy of electroacupuncture in acute and chronic phases of radial and ulnar nerve injuries in histopathological, immunohistochemical and biochemical aspects. In the study, the rabbits were divided into four groups namely acute nerve injury (ANI) group, chronic nerve injury (CNI) group, positive control (PC) group and negative control (NC) group. In the ANI, CNI and PC groups, damage was created on the nervus radialis and nervus ulnaris by applying pressure for 60 seconds using a hemostatic forceps under anesthesia. No damage was created in the NC group. Fifteen sessions of electroacupuncture were applied to the rabbits in the ANI, CNI, and NC groups every other day using LI-4 (Large Intestine Meridian-4, He Gu), LI-10 (Large Intestine Meridian-10, Shou San Li), LR-3 (Liver Meridian-3, Tai Chong), and ST-36 (Stomach Meridian-36, Zusanli) electroacupuncture points. Electroacupuncture was not applied to the rabbits in the PC group. Decapitation was performed under general anesthesia at the end of electroacupuncture applications. After the euthanasia procedure, the samples obtained were evaluated for histopathological, immunohistochemical and biochemical parameters. In conclusion, degenerative foci in the treatment groups were found to be fewer than in the PC group whereas NGF and S-100 immunoreactivity were higher in the treatment groups than in the PC group. Whereas no statistically significant difference was observed between the treatment groups and the NC group in terms of oxidative stress factors, there was a statistically significant difference between the treatment groups and the PC group. In light of all these data, we have concluded that electroacupuncture is an effective treatment method for peripheral nerve injuries.

Opis:
The upper Campanian (Cretaceous) of the Hacımehmet area (south of the city of Trabzon; Eastern Pontides) is mainly composed of calciclastic turbidites. The basinal unit of the 119 m thick succession includes thin red pelagic limestone interlayers and conglomerates dominated by volcanic clasts. The overlying upper slope and lower slope units of the sequence consist of an alternation of allochthonous calcarenite/calcirudite beds and pelagic marls and mudstones. Calcarenite/calcirudite beds dominate the upper slope unit of the succession and are composed of transported material, including benthic foraminifers, red algae, bryozoan, crinoid and rudist fragments, inoceramid bivalve prisms and neritic and pelagic carbonate lithoclasts. The occurrence of Helicorbitoides boluensis (Sirel) extracted from the calcarenite/calcirudite beds indicates a Campanian age. Identifiable rudists such as Joufia reticulata Boehm, Bournonia cf. anatolica Özer, Biradiolites cf. bulgaricus Pamouktchiev and ?Biradiolites sp. from the upper slope unit of the succession indicate a late Campanian–Maastrichtian age. The planktonic foraminifers within the red pelagic limestone beds, marls and mudstones throughout the succession consist mainly of Campanian–Maastrichtian forms and suggest mainly basinal depositional conditions. The presence of Radotruncana cf. calcarata (Cushman) accompanied by Globotruncanita elevata (Brotzen) in the basinal unit of the succession indicates an early late Campanian age for the lower part of the succession. Inoceramid bivalves have been collected from the upper part of the succession. The fauna is dominated by ‘Inoceramus’ tenuilineatus Hall and Meek, 1854 and Cataceramus haldemensis (Giers, 1964); other taxa recognised are: ‘Inoceramus’ algeriensis Heinz, 1932, Platyceramus vanuxemi (Meek and Hayden, 1860), ‘Inoceramus’ cf. nebrascensis Owen, 1852, Cataceramus aff. barabini (Morton, 1834), Cataceramus gandjaensis (Aliev, 1956), and ‘Inoceramus’ sp.; the assemblage indicates the ‘Inoceramus’ tenuilineatus Zone; corresponding to the middle–late Campanian boundary interval. The uppermost part of the succession is characterized by the presence of the trace fossils Scolicia strozzii and Scolicia isp., indicating a mixed Skolithos-Cruziana ichnofacies. This ichnofacies suggests a well-oxygenated environment.
