Boolean expressions are major focus of specifications and they are very much prone to introduction of faults, this survey presents various fault based testing techniques. It identifies that the techniques differ in their fault detection capabilities and generation of test suite. The various techniques like Cause effect graph, meaningful impact strategy, Branch Operator Strategy (BOR), BOR+MI, M...

Bu çalışmada, elyaf bor fiber takviyeli prepreglerin (Specialty Materials 5505 Boron Epoxy Prepreg Tape) epoksi reçine (Hexcel RTM6) kullanılarak serim yöntemi metodu ile tabakalı kompozit malzeme üretilmiştir. Üretilen malzemeler 9 kat olacak şekilde nano ilaveli ve olmayacak iki farklı hazırlanmıştır. Bir grup numunede sadece kullanılırken diğer içerisine deneme (akışkanlığa bakılarak) % 0.07...

Direct borohydride fuel cells (DBFC) oxidize an easily-stored energy-dense (sodium borohydride: NaBH4), that in theory reacts ca. 400 mV below H2 and produces 8 electrons per BH4- anion. However, the oxidation reaction (BOR) does not fully meet these promises practice: electrocatalyst nature, structure state-of-surface, operating conditions (pH, concentration, temperature, fluxes) noticeably in...

The structural genes for threonyl-tRNA synthetase (ThrRS) and phenylalanyl-tRNA synthetase (PheRS) are closely linked on the Escherichia coli chromosome. To study whether these enzymes share a common regulatory element, we have investigated their synthesis in mutants which were selected for overproduction of either ThrRS or PheRS. It was found that mutants isolated previously for overproduction...
