Otizm Spektrum Bozukluğu (OSB) birçok gelişim alanında kendisine özgü sorunlara sahip nörogelişimsel bir bozukluktur. OSB’de refleks ve motor ile duyusal işlevsellik üzerine çeşitli araştırmalar mevcuttur ancak Fear Paralysis Refleks (FPR) Moro ilişkilendirilmiş çalışmalar sınırlıdır. FPR Moro, harmonisinin ilk gelişen refleksleri kendilerinden sonraki reflekslere temel geçit olmaları açısından...

In Escherichia coli, the biosynthesis of the electron carrier menaquinone (vitamin K2) involves at least seven identified enzymatic activities, five of which are encoded in the men cluster. One of these, the conversion of o-succinylbenzoic acid to 1,4-dihydroxy-2-naphthoic acid, requires the formation of o-succinylbenzoyl-CoA (OSB-CoA) as an intermediate. Formation of the intermediate is mediat...

The emissions of volatile organic compounds (VOCs) from structural insulated panel (SIP) materials were investigated. Specimens of newly produced SIPs and associated panel adhesives were obtained from two relatively large manufacturers. Additionally, specimens of the oriented strand board (OSB) used as the inner and outer sheathing and the extruded polystyrene core for the SIP were obtained fro...

Oriented strand board (OSB) is an important engineered wood product manufactured through bonding of strands in cross-oriented layers. The bending strength, one the crucial properties for loadbearing material, OSB strongly depends on its structural characteristics. To understand strength OSB, strain distribution was continuously monitored during a three-point test using digital image correlation...

In modern DSL systems, multi-user crosstalk is the major source of performance degradation. Optimal Spectrum Balancing (OSB) is a centralized algorithm that optimally allocates the available transmit power over frequencies, thereby mitigating the effect of crosstalk. OSB uses Lagrange multipliers to enforce constraints that are coupled over frequencies. However, finding the optimal Lagrange mul...
