“…And the activation energy is usually approximated described by a Gaussian distribution. 20 Researchers have made a lot of research on biomass pyrolysis by the three-parallel-DAEM-reaction model, which assumes three independent parallel reacting pseudocomponents (cellulose, hemicellulose and lignin). [21][22][23][24][25] It was further assumed that the pyrolysis kinetics of each pseudocomponent can be described by the single Gaussian-reaction-DAEM.…”

This work deals with the pyrolysis kinetics of cellulose, hemicellulose and lignin. Experiments were carried out in a thermogravimetric analyzer (TGA Q5000) in the inert atmosphere of nitrogen at a heating rate of 10 K min À1 . The single Gaussian distributed activation energy model (DAEM) was utilized to study the pyrolysis kinetics. Kinetic parameters such as the pre-exponential factor (k 0 ), mean activation energy (E 0 ) and standard variance (s) were computed by a pattern search algorithm. It was found that the calculated kinetic parameters using the single Gaussian-DAEM-reaction model could reproduce the differential thermogravimetric (DTG) curves of cellulose very well. However, there existed obvious deviations in the whole range of temperatures between the calculated and experimental data for hemicellulose and lignin.In order to describe the thermal decompositions of hemicellulose and lignin more accurately, a novel double Gaussian-DAEM-reaction model consisting of two parallel partial reactions was developed to describe the pyrolysis processes. Calculated results of the fitting procedure using the double Gaussian-DAEM-reaction model showed good agreement with experimental DTG data of hemicellulose and lignin.

“…For Thai lignite at slow heating rates (5-50 K/min), Tia et al (1991) observed that the activation energy derived from SFORM is the same for the different heating rates and the frequency factor is strongly influenced by heating rates. The effect of heating rates on the numerical solution of DAEM equation has been investigated in another study (Güneş and Güneş, 1999). According to obtained results, the heating rate (from 5 to 5000 K/min) has little effect on the solution of DAEM equation in comparison with E 0 and σ .…”

Fashion is a phenomenon with a complex structure that changes according to time and place. Innovations in the form of clothing played an important role in the development of fashion. The idea of having a different style of clothing and being liked more paved the way for the emergence of fashion trends. Therefore, the importance of trademark image in the fashion sector has increased gradually. While consumers prefer the fashion trademark, they are more influenced by the trademark image. For this reason, trademark has become very important for businesses in the fashion sector. However, in order to become a trademark owner in the fashion sector, enterprises and undertakings should not have absolute refusal grounds at the time of trademark application. The absolute refusal grounds are related to public order and are therefore protected by international and national regulations. The absolute refusal grounds in our country have been prepared in Article 5 of Industrial Property Law No. 6769 in line with the European Union Directives and the agreements signed within the European Union. In this study, the absolute refusal grounds are discussed within the scope of Article 5 of Industrial Property Law No. 6769. In this direction, an evaluation was made in line with the recommendations of the European Court of Justice and the decisions of the Court of Cassation. In addition, the absolute refusal grounds were examined and examples from fashion and textile sectors were given.
