Characterization of a 2,2-dichloropropionic acid (2,2-dcp) degrading alkalotorelant bacillus megaterium strain bhs1 isolated from blue lake in Turkey

Yılmaz KAYA

An acid, 2,2-dichloropropionic acid (2,2-DCP) is an active ingredient in herbicide (Dalapon®). Using 2,2-DCP as a model substrate, an alkalotolerant bacterium was successfully isolated from the Blue Lake, Turkey. This bacterium is a potential bioremediation agent of recalcitrant xenobiotic halogenated compounds. This study aimed to prove the efficacy of the alkalotolerance Bacillus megaterium BHS1 in degrading 2,2-DCP as the sole source of carbon. Biolog GEN III system and 16S rRNA analysis were used for the identification of the bacterium. It was discovered that the strain BHS1 is Bacillus m ...More

Sorption characteristics of zeolite and bentonite natural adsorbents modified complex

Zarlık MAYMEKOV

The main objective of our study is to obtain a complex compound from natural adsorbents to purify wastewater with simultaneous sorption of chemical and microbiological substances contained therein, which contribute to disinfection and softening of water, increasing the degree of treated water saturation with calcium, magnesium salts and trace elements, while not requiring the use of sophisticated equipment. The technical result is to create a complex of adsorbents with the sorbing ability of chemical and microbiological pollution, disinfecting and softening water, enriching it with calcium ion ...More

Agrobacterium- mediated transformation of Turkish upland rice (Oryza sativa L.) for Dalapon herbicide tolerance

Yılmaz KAYA | İbrahim İlker ÖZYİĞİT | Ali ASLAN

Agrobacterium-mediated transformation of upland rice is established in few numbers of cultivars due to the high cultivar-specificity of regeneration from transformed explants. Further, dehalogenase E (dehE) gene had been characterized in Pseudomonas putida and it produces an enzyme that degrades dalapon. This study aimed to transform Turkish upland rice with the dehE herbicide resistant gene and addresses the challenges of transgenic rice recovery by identifying explant and transformation method. Constructed vector pCAMdehE carrying dehE gene was transferred into the rice shoot apex by Agrobac ...More

Solution of the Maximum of Difference Equation

Dağıstan ŞİMŞEK | Burak OĞUL | Fahreddin ABDULLAYEV

In the recent years, there has been a lot of interest in studying the global behavior of, the socalled, max-type difference equations; see, for example, [1-17]. The study of max type difference equations has also attracted some attention recently. We study the behaviour of the solutions of the following system of difference equation with the max operator:paper deals with the behaviour of the solutions of the max type system of difference equations, x(n+1) = max {A/x(n-1) , y(n)/x(n)}; y(n+1) = max {A/y(n-1) , x(n)/y(n)}, (1) where the parametr A and initial conditions x(-1), x(0), y(-1), y(0 ...More

Statistical Models of EAF Harmonics Developed for Harmonic Estimation Directly from Waveform Samples Using Deep Learning Framework

Özgül SALOR-DURNA

In this paper, a method to generate large amounts of Electric Arc Furnace (EAF) currents with harmonics simulating the actual EAF operation characteristics to be used with deep learning (DL) applications of harmonic estimation is investigated. For this purpose, the behavior of the EAF current harmonics is examined in statistical terms using the field data collected at a transformer substation supplying an EAF plant. Then, a significantly larger amount of EAF current data is generated using the statistics mimicking the real EAF behavior to train the DL-based harmonic estimator. The outcomes of ...More

Effect of human development level of countries on the web accessibility and quality in use of their municipality websites

Rita İSMAİLOVA

This study aimed to explore the relationship between human development index (HDI) of countries and level of web accessibility and quality in use of their municipality websites. A list of 146 countries was obtained from the 2016 Global Human Development Report of the United Nations. Of these countries, 49 had a very high HDI, 42 had a high HDI, 33 had a medium HDI, and 22 had a low HDI. For the analysis of web accessibility and quality in use, the official municipality websites of capital cities of each country were found. These websites were tested using automated evaluation tools. The result ...More
