Article A Survey On the Visibility Of Mosaic Heritage On The UNESCO World Heritage List(Bursa Uludağ University, 2025) Akture, Z.World Heritage Programme was launched under the auspices of UNESCO by adopting the Convention concerning the Protection of the World Cultural and Natural Heritage in 1972. 1223 cultural, natural, and mixed properties have been inscribed on the World Heritage List (WHL) from 1978 to 2024 to ensure international consideration and assistance in their preservation as patrimony of humanity. This paper offers an insight into the visibility of mosaic heritage in this corpus through a survey of references to mosaics in the Statements of Outstanding Universal Value (OUV) on the homepages of World Heritage properties at UNESCO’s website. After an introduction on the requirements for inscription on WHL, distribution of mosaics in World Heritage properties is surveyed in reference to their category, location on the globe, and setting within the property to highlight over- and under-representations, with inspiration from the current strategy of achieving a balanced representation of heritage types, chronologies-regions, and themes on WHL. Then selected “exceptions” in terms of mosaic types, locations, and periods are presented to contribute in increasing their visibility, followed by “highlights” in whose Statements of OUV the word “mosaic” is most repeated. Adopting the wholistic approach recommended in the World Heritage Programme, both sections aim to contextualise the selected examples in the overall corpus and mosaic heritage as an element forming and representing their attributes of OUV. After observing the thus exemplified variety in the mosaic heritage so far inscribed on WHL, concluding remarks highlight areas of further research to deepen the presented visibility analysis. © (2024), ().

The results show that on clean Co(111), hydrogen sulfide dissociation proceeds fast due to low activation barriers, yielding atomic sulfur on the cobalt surfaces. Boron promotion hinders the dissociation of hydrogen sulfide due to increased activation barriers. Furthermore, boron prevents the interaction of sulfur compounds with cobalt surface atoms, as these poisons bind on boron. The findings indicate that boron is an effective promoter that can be used to design sulfur resistant cobalt catalysts. © 2024, Sakarya University.

However, continuous organic and inorganic precursor load and disinfectant dosing make pool water chemistry much more complex than other disinfected waters. Carcinogenic bromate compound is one of the hundreds of disinfection by-products in pool water. The occurrence of bromate in pool waters depends on the precursor content of filling water, the disinfection process, operating parameters, and the purity of disinfectants. While the average filling water bromide concentrations of University Campus indoor swimming pool in Gülbahçe –Urla (SP1) and Buca public indoor swimming pool (SP2) were determined to be 182 μg/L and 11.0 μg/L, respectively, the average bromate concentrations of SP1 and SP2 were 59.4 μg/L and 68.3 μg/L. Estimated chronic-toxic health risks of accidental ingestion of pool water during swimming (between 10-3 and 10-1) were lower than the threshold level (‘1’). Although the carcinogenic risks in central tendency scenario (<10-6) indicate negligible risks for swimmers, worst case scenario indicates carcinogenic risks (medians were ranged from 1.61×10-6 to 9.42×10-6) for highly exposed specific swimmer groups. Bromate accumulation in swimming pools needs attention for mitigating the health risks for swimmers. © 2021, Yıldız Technical University.Article Citation - WoS: 4Impact of Window-To Surface Area for Different Window Glass Types and Wall Orientations on Building Energy Performance: a Case Study for a School Building Located in Izmir, Turkey(Yıldız Teknik Üniversitesi, 2011) Yildiz, Yusuf; Ozbalta, Trkan Goksal; Arsan, Zeynep DurmusThe opaque and transparent surfaces of buildings have an important role in the total percentage of energy loss or gain. Heat loss or gain from windows are dependent on the window-to-wall area ratio, the window glass type, and the type of window frame used. In the concept of energy efficient design, heat loss or gain from windows should be analyzed in detail in the early stages of building design by considering local climatic conditions. This study investigates a school building located in Izmir in Turkey, a city with a hot and humid climate. Various glass types with different glazing characteristics and number of layers, located in different parts of the buildings and with different window-to-wall ratios are analyzed and compared using building the energy analysis program "EnergyPlus". Results indicate that window-to-wall area ratios, wall orientation and glass types are important factors in the building's total energy consumption. When the window-to-wall area ratio is increased from 10% to 60%, the winter heating load of the building decreases in maximum amount on the south side of the building and reduces in minimum amount on the east side of the building. When summer cooling load is investigated the highest increase in energy consumption is found on the south side of the building. On the eastern and western sides of the building the effect of increased energy consumption value remains low. When the total energy consumption (cooling + heating) is considered, it is calculated that the east and west sides have the biggest total effect and the northern wall has the smallest total effect. When low emissivity glass is used instead of double layer glass, in terms of energy consumption the building side order of effect remains the same, although actual values differ. It is therefore clear that using energy analysis programs to analyse different factors within the energy consumption of buildings will be beneficial in creating energy efficient solutions. This can be carried out in the earlier stages of the architectural design of the buildings or at the renovation stages of existing buildings.Article Military Intelligence Deeds in the Reports of Izmir British Consulate General (1878-1914)(Ege Univ, 2011) Aditatar, FundaFrom 1825 up to the late nineteenth century the British Levant Consular Service developed highly parallel with the policy of Britain in the Ottoman Empire. During the protection policy of the Ottoman territory which continued until the 1870s, political and commercial aspects of consular services has been formulated almost an equal level. Instead of protecting the territorial integrity of the Empire after the Berlin Treaty of 1878 turned into a controlled sharing and consuls began press to served heavily political direction. The aim of this paper is to evaluate reports of Izmir British Consulate about military intelligence. The voluminous reports of the consulate related with the military intelligence. This situation occurs in Izmir because of commercial importance and strategic location, and also riots and wars all of these can be explained in the intensive military mobility during the last period of the Empire (1878-1914).Article Citation - WoS: 7Investigation of Educational Buildings in Terms of Daylighting Performance(Yıldız Teknik Üniversitesi, 2011) Erlalelitepe, Ilknur; Aral, Duygu; Kazanasmaz, TugceEducational buildings have the priority among other building types in daylight performance studies. There are several reasons for this. Classrooms which are used during the whole day should have sufficient and homogeneously distributed daylight. In insufficient daylight conditions, the use of electrical lighting increases energy consumption. Users' visual comfort should also be assured, and design incorporating natural light requires the analysis of sun protection devices in order to avoid glare and excessive heat. Also, atriums and skylights can be included in the building design with the aim of distributing light equally and in a relatively balanced manner throughout the building. However, lighting schemes are often proposed by architects and professionals who tend to make use of different design tools, and it would be pertinent to investigate whether these tools perform as desired. This study analyses daylight design principles and design elements in educational buildings. It outlines the method which has been used to analyse the daylight performance of buildings. A university building was selected for the field study. Measurements were taken in sample spaces to determine daylight performance. Utilising comparison between standard values and measured values, findings are presented in the form of tables, drawings and figures.Article A Fuzzy Logic Model To Classify Design Efficiency of Nursing Unit Floors(Yıldız Teknik Üniversitesi, 2010) Kazanasmaz, Tugce; Tayfur, GokmenThis study was conducted to determine classifications for the planimetric design efficiency of certain public hospitals by developing a fuzzy logic algorithm. Utilizing primary areas and circulation areas from nursing unit floor plans, the study employed triangular membership functions for the fuzzy subsets. The input variables of primary areas per bed and circulation areas per bed were fuzzified in this model. The relationship between input variables and output variable of design efficiency were displayed as a result of fuzzy rules. To test existing nursing unit floors, efficiency output values were obtained and efficiency classes were constructed by this model in accordance with general norms, guidelines and previous studies. The classification of efficiency resulted from the comparison of hospitals.Article Citation - WoS: 2The Development of Western-Type Large-Scale Consumption Areas in Turkey and Legal and Structural Regulation Efforts in Urban Retail Environments(Yıldız Teknik Üniversitesi, 2009) Kompil, Mert; Celik, MuratThe retail sector has been experiencing a rapid and continuous change worldwide. There have also been profound changes in Turkey, especially after the 1980s. Both the retail sector and the urban retail environments have been altered radically. One of the most significant indicators of this change is the proliferation of western-type large-scale retail developments. Past experiences in developed countries have shown that the uncontrolled development of large-scale retail areas results in some undesired socioeconomic and physical outcomes, such as decline in the cultural and commercial activities of city centers, damage in existing retail workforce structure, and change in local retail hierarchy, nearby land uses, traffic loads and original architectural identity. Many countries have put into practice restrictive and regulatory policies to prevent these negative effects. As similar transformations have also been realized in Turkish retail environments, many institutions think that similar legal regulations must be implemented in Turkey as well. The present study investigates the ongoing retail change within the Turkish context, explores the legal and structural regulatory policies of the Organization for Economic Co-operation and Development (OECD) countries, and critically discusses the appropriate retail regulation policies for Turkey.Article Efficient Design of Nursing Unit Floors(Yıldız Teknik Üniversitesi, 2009) Kazanasmaz, Z. Tugce; Duzgunes, ArdaHospital designs aim to obtain the lowest possible construction, maintenance and operational costs together with patient satisfaction, comfort and privacy. To satisfy these needs, the efficient design of nursing unit areas becomes considerably important. This study was thus conducted to analyze planimetric design efficiency of nursing unit floors by defining certain floor areas and floor area ratios. To test existing nursing unit floors, quantitative assessments were noted in regard to their planimetric efficiency: the utility value of the built floor area, both in terms of its allocation to patient space (served), support (serving) and circulation space and the relative proportions of these. Results were presented in a comparative table. Of the 15 hospital floor plans analyzed, five satisfied minimum space requirements for patient areas, while another five were in the optimum range for circulation areas. Two were defined as the least efficient, having the lowest patient-to-circulation area ratio.Article Citation - WoS: 1Hydrogeochemical and Hydrogeological Investigation of the Can Geothermal Field(TMMOB Jeoloji Mühendisleri Odası, 2010) Deniz, Ozan; Baba, Alper; Tarcan, GultekinThe Can Geothermal Field is located on a central part of the Biga Peninsula in northwest Turkey. Volcanics are the dominant rock type in this region. Alteration zones and clay minerals are very common in these rocks. Sedimentary rocks, low-grade metamorphics and alluvium are other geological units observed around Can. These units include common fracture zones because of the tectonic activity in the region. Thermal waters have reached the surface via these fracture zones. Alluvium is the most productive aquifer in all geological units. Wells drilled in this unit yield between 5-30 L/s. The transmissibility and permeability coefficients of this unit are of 50-421 m(2)/day and of 1.01-16.8 m/day, respectively. In this aquifer, groundwater depth changes between 0.1 and 8.3m. According to the IAH (1979) water classification, these thermal waters are of the Na-Ca-SO4 type, the cold waters are of the Ca-Mg-HCO3 type and the snow samples are of a mixed water type. Geothermal waters have a meteoric origin. The mean temperature, electrical conductivity and pH of the thermal waters have values of 44.4 degrees C, 2941 mu S/cm and 6.9, respectively. Geothermometer equations were used for prediction of reservoir fluid temperatures of the geothermal system and temperature values were obtained between 46 and 203 degrees C. delta D, delta T and delta O-18 isotope analysis showes that thermal waters in the Can region have a meteoric origin and are a minimum of 45-50 years old.
