Effect of delamination size, location and boundary conditions on the behavior of a laminated glass plate

Ebru DURAL

Laminated glass is made by combining glass layers with polyvinyl butyral (PVB) or a different adhesive with the help of heat and pressure. Its popularity is increasing in the building industry as a protective material. However, despite the popularity of laminated glass as a structural material, delamination is recognized as a highly undesirable problem inducing major damage to laminated glass. The effect of boundary conditions on the delamination strength of laminated glass is observed in this study. It is concluded that the location and size of delamination have a considerable effect in deter ...Более

Understanding digital diplomacy through Ukraine-Russia events: The truth behind events in Ukraine and donbass

Niyazi AYHAN | Tolkun Bekturgan Kızı

Digital diplomacy is a form of new public diplomacy that uses the internet, new information and communication technologies, and social media as a means to strengthen diplomatic relations. The main differences from classical public diplomacy are greater access to information, more interaction between people and organizations, and greater transparency. Diplomacy is radically transforming in front of our eyes. In the face of new challenges, its structure and methods are changing, and new directions are emerging. The chapter analyzes new opportunities and technologies for use by the diplomatic dep ...Более

Cotton Agriculture in Turkey and Worldwide Economic Impacts of Turkish Cotton

İbrahim İlker ÖZYİĞİT

Cotton is a product that provides wealth for humanity with its widespread and compulsory usage, and alongside creating employment opportunities in the producer countries. Due to the availability of suitable land for agriculture, seven countries including Turkey produce close to 80% of cotton worldwide. The average cotton yield in Turkey is above the world average, placing the country close to first place among the major producing countries. On the other hand, Turkey is one of the main countries engaged in organic cotton production by using only non-transgenic seeds and therefore, its cotton as ...Более

Technological intelligence for circular supply chain: a co-citation analysis approach

Serhat BURMAOĞLU

Purpose The COVID-19 pandemic has disrupted the supply chains, and this brought researchers and practitioners to think about more on circular supply chains (CSC). The CSC concept has been discussed in the literature more than a decade. This study aims to find out the theoretical roots of CSC by analyzing scholarly articles in literature. Design/methodology/approach This paper uses document cocitation analysis for reaching this aim. After retrieving data from Web of Science database, this paper explores data set by considering used references of these publications and clusters them based on the ...Более

Inverse design of ultra-compact photonic gates for all-optical logic operations

Mirbek TURDUEV

Logic gates have great importance in realization of rapid data transmission as well as low loss transfers. In this paper, a multi-objective inverse-design approach is implemented by using objective-first algorithm to design optical AND, OR, NAND and NOT logic gates on Si-platform at the design wavelength of 1.30 mu m. For all gates, the design area is fixed to 2.24 mu m x 2.24 mu m. The optical logic '1' output is accepted to be optical power values greater than 0.8 times of the input optical power. By implementing a Bias waveguide as well as two input ports, we made it possible to achieve log ...Более

Future research avenues at the nexus of circular economy and digitalization

Serhat BURMAOĞLU

Purpose The authors posit that one of the key enablers of the circular economy will be the digital transformation - in other words, digitalization. In this study, the authors examine and visualize the interaction of the circular economy and digitalization by using scientific publications. They explore possible synergies and future research avenues at this junction. Design/methodology/approach The authors first apply bibliometrics to explore and visualize the relationships between the circular economy and digitalization in the academic literature. Following the clustering of topics, they define ...Более

Determination of Propagation Constants and Wave Impedance of Non-Reciprocal Networks From Position-Insensitive Waveguide Measurements

Mehmet ERTUĞRUL

A microwave method is proposed to determine the forward and backward propagation constants (gamma ⁺ and gamma ⁻) and the wave impedance ( z_w ) of reciprocal and non-reciprocal microwave networks whose positions are not known within their measurement cells (position-insensitive). The proposed method relies purely on analytical expressions and can also evaluate the reference plane transformation distances. Scattering parameter measurements at the X-band (8.2-12.4 GHz) of a reciprocal network (a waveguide straight) and a non-reciprocal network (a microwave phase shifter) arbitrarily positioned i ...Более

Synthesis and characterization of carboxymethyl cellulose (CMC) from different waste sources containing cellulose and investigation of its use in the construction industry

Mustafa DOLAZ

This study aimed at the recovery of cellulose from abundantly available wastes and its sustainable application. Firstly, in the cleaning process, cellulose-containing wastes, such as air particle vacuum powder (APVD), towel clippings (TC), and cottonseed delintation residues (CD), were thoroughly washed, separately, with tap water to remove some organic and inorganic impurities. The cotton slurry was purified by 17.5 NaOH at 90 degrees C for about 4 hours, then filtered and washed with tap water. Afterwards, the resulting pulp was bleached by NaOH and H2O2 , and washed with distilled water unt ...Более
