Novelty and distinctive character are the conditions of protection for a registered design in Turkey. This study investigates the ways in which novelty and distinctive character are interpreted and assessed by the parties actively involved in the assessment process &ndash / judges, court experts, the Turkish Patent Institute experts, attorneys and design agents. The face-to-face interviews conducted with 51 participants from the parties involved indicate that the assessment of distinctive character presents more challenges than the assessment of novelty. Not being exactly the same with a previous design is the main consideration in the assessment of novelty. The assessment of distinctive character is primarily identified with the comparison of designs&rsquo / overall impressions whereas designer&rsquo / s degree of freedom remains as the least mentioned consideration. The study suggests that being subject to protection of designs not fulfilling the conditions of protection coupled with the uncertainties in the assessment of novelty and distinctive character, which may have a negative impact on the public trust in the design registration system. The study concludes with a set of suggestions for developing an assessment guide for the design registration system in Turkey.

The study of Japan has too often been premised upon a crude presupposition that any intellectual or artistic production is predetermined by the structure of Japanese language or culture. This rather culturalist assumption can be sustained only by a refusal to entertain theoretical critiques. This article shows that the typical culturalist argument about Japanese literature is based upon a misconception of translation and the accompanying essentialist view of language.

In this study, possible cleaner production opportunities for a dairy processing facility are examined, considering the market milk production process. Cleaner production concept and its key tools of implementation were analyzed to build the basis of study. General production process and its resulting environmental loads are discussed by taking possible CP opportunities as the axis of study. A methodology is developed for cleaner production opportunity assessment in Milk Processing Facility of Atat&uuml / rk Orman Ciftligi. The methodology covers two major steps / preparation of checklists for assisting auditing and opportunity assessment / implementation of the mass balance analysis. For mass balance analysis, measurements and experimental analysis of the mass flows are utilized to determine the inputs and outputs. Prepared check lists are utilized to determine waste reduction options that could be implemented. Selected opportunities are evaluated considering its environmental benefits and economic feasibility.

The slags from iron-steel and zinc industries are rich in metal oxide contents like FeO, MnO, CaO. However, these slags are not used extensively, except some usage in the cement industry. These slags can be used in removing H2S from waste gases from different industrial sources. The purpose of this research is to study the effect of initial concentration of H2S on the capacity and sorbent efficiency of waste materials from iron-steel and zinc industries. Experiments were conducted in a 25 mm-quartz reactor with simulated gases containing H2S as reactive gas. Breakthrough curves for sulfidation reactions were obtained for 3000 ppmv, 4000 ppmv and 5000 ppmv initial H2S concentrations at the reaction temperature range of 500&deg / C&ndash / 700&deg / C. According to the results obtained from the experiments, the H2S removal capacity of both slags increased with increasing reaction temperature, however, the H2S removal capacity of the slags decreases as the initial H2S concentration increases. Cyclic sulfidation and regeneration tests were applied to both steel and zinc slags in order to determine the regenerability of the slags. In cyclic tests, zinc slag gave better results than steel slag. A &ldquo / Deactivation Model&rdquo / was used in order to fit the breakthrough curves obtained experimentally to the breakthrough curves predicted from the deactivation model. A very good fit was obtained for both steel and zinc slags. Zinc slag was shown to be more suitable for gas cleanup than steel slag taking into account its high H2S removal efficiency, regenerability and low cost (almost free of charge).

The improvement of construction systems and management systems do not move together in construction industry, not using the effective management approaches decrease the productivity of the work. The firms both in national and international area in manufacturing industry use supply chain management to preserve their competitive force. As material costs account for a high percentage of the overall cost, the success of a project is heavily dependent on material related factors and processes. In Turkey because of extensively using in-situ concrete in construction, the supply chain for reinforcement and concrete is very important. One of the components of concrete is &ldquo / re-bar&rdquo / and its supply chain, rbSC (rebar supply chain) was investigated within the scope of this research. In this study a framework was developed on the basis of the information from a literature survey and a field-test consisting of face-to-face interviews and questionnaire to determine the factors affecting the rbSC externally and those related to the supply chain participants. The developed rbSC performance framework was analyzed with Structural Equation Modeling rules. LISREL software was used, and the outputs of LISREL were evaluated by relationing with the information obtained from literature survey. The developed framework can be used to maximize both effectiveness of the rbSC process and efficiency of time and cost related issues in the rbSC. rbSC performance was associated with the project performance at the end of the study to reach a higher-level scale. The difference between the performance ratings obtained by self-assessment of a participant and those obtained through assessment done by the others was used to determine the affects of cultural issues on performance. Common reasons for the lower performance were analyzed due to cultural context and recommendations were set down for rbSC participants to solve the problems.

Conventional methods used in the structural analysis are usually insufficient for the analysis of historical structures because of the complex geometry and heterogeneous material properties of the structure. Today&rsquo / s computing facilities and methods make FEM the most suitable analysis method for complex structural geometry and heterogeneous material properties. Even the shrinkage, creep of the material can be considered in the analysis. Because of this reason Finite Element Method (FEM) is used to analyze such structures. FEM converts the structure into finite number of elements with specific degree of freedoms and analyses the structure by using matrix algebra. However, advanced FEM methods considering the inelastic and time dependent behavior of material is a very complex and difficult task and consumes considerable time. Because of this reason, to analyze every historical structure is not feasible by applying advanced inelastic FEM, whereas elastic FEM analysis at low load levels is very helpful in understanding the behavior of the structure.The analysis of a masonry gate in the historical city, Hasankeyf is the case study of this thesis. Different common software are used in FEM to compare the stresses, deformations, modal shapes etc. of the same structure. Besides the inelastic behavior of the structure is investigated and compared with the elastic behavior of the structure. The study is intended to show that at the low load levels elastic FEM analysis is sufficient to understand the response of the structure and is preferable to the inelastic FEM analysis unless a very complex analysis is required

Glass is an inherrently strong and elastic building material that allows the enclosure of spaces to provide both comfort and &aelig / sthetic appeal. It is evidently due recognition of these properties that has resulted in the current propensity to use it in ever larger sizes / and then with minimum&ndash / if not total absence&ndash / of visible supporting structure. It is, however, its lack of plastic behavior under stress&ndash / leading to catastrophic failure without warning&ndash / that has been the main drawback preventing its use as a structural material on its own. Ergo, the development of composite configurations with plastic interlayers, commonly known as structural glass. Contemporary working methods for glass have also been able to provide better structural characteristics&ndash / particularly after heat treatments, which reduce its vulnerability to cracking and brittle failure. In com-bination, these methods offer designers the possibility of using glass panels capable of acting as load-carrying structural elements. The aim of this study was to investigate the performance of glass-adhesive-glass composite, or laminated, elements and the use of glass as a structural material in light of their inherent strength properties. Here, an attempt was made to define the be-havior of interlayers in structural glass and to then prepare a selection guide. To this end, it was necessary to first gather information about the materials and design methods used to create glass structures. As the literature notes that such stresses are particularly important to structural glass design due to the inability of the material to flow plastically and to thus relieve high stresses, pertinent simulation techniques (e.g., finite element analysis) were then used to investigate shear transfer between glass panes and interlayers. These simulations allowed determination of stiffness with different types of interlayer for panes of different dimensions and orien-tation in respect to loading conditions. It was the results of these analyses that were finally compiled into the selection guide already noted. It is expected that these results will make a worthwhile contribution to developing glass structure design and its application in practice.

The Integrated Pollution Prevention and Control (IPPC) Directive from the European Union strives to achieve a high level of environmental protection by preventing or reducing the pollution emanating from industrial installations directly at the source. The Directive implies that the emission limit values should be set in accordance with each industry&rsquo / s Best Available Techniques (BAT). In the present study, water recovery and wastewater treatability alternatives developed beforehand were evaluated towards the evaluation of BATs for the management of wastewaters from a denim textile mill. For this purpose, an assessment that translates the key environmental aspects into a quantitative measure of environmental performance and also financial analysis were performed for each of the alternatives. The alternatives considered for water recovery from dyeing wastewaters were nanofiltration (NF) with coagulation and/or microfiltration (MF) pretreatment, ozonation or peroxone and Fenton oxidation. On the other hand, for the end-of-pipe treatment of the mill&rsquo / s mixed wastewater / ozonation, Fenton oxidation, membrane bioreactor (MBR) and activated sludge process followed by membrane filtration technologies were evaluated. The results have indicated that membrane filtration process providing 70 % water recovery with the least environmental impacts is the BAT for water recovery. On the other side, MBR technology has appeared as the BAT for the end-of-pipe treatment of the mill&rsquo / s mixed wastewater. A technical and financial comparison of these two BAT alternatives revealed that water recovery via membrane filtration from dyeing wastewaters is selected as the BAT for the water and wastewater management in the mill.

Advances in technologies and the idea of incorporating technological solutions into buildings have made it possible to provide more comfortable and secure spaces for living or working. The term &ldquo / intelligent building&rdquo / is becoming very popular in terms of attaching prestige to a project and improving its desirability. However too many buildings are claimed to be intelligent and adaptive to change but, without an appropriate understanding of intelligent building concept and also capabilities of assessing an intelligent building, it is not possible to judge such claims. In view of the fact that truly intelligent buildings provide their occupants with efficient facilities and comfortable space, many experts and researchers have discussed the characteristics of intelligent buildings and come up with different definitions and assessment systems, but none agree with each other completely. The aim of this study was to evaluate intelligence in intelligent buildings and provide responsiveness clues in terms of system efficiency and user convenience to find out whether buildings claimed to be intelligent meet the intelligence requirements or not. v After conducting a literature survey to identify main intelligence characteristics, two buildings both claimed to be intelligent and able to provide occupants with healthy, secure and comfortable space, were selected as the case studies. The intelligent building principals and specific design considerations together with efficient system integration and system requirements were examined in the case studies. It was concluded that, even though case studies were admired in terms of holding commercial value and applying new technologies but there existed a lack in either employing or incorporating that technologies to meet desired responsiveness and dynamism which, are main attributes of intelligent buildings.
