We calculate the number of photons produced by the parametric resonance in a cavity with vibrating walls. We consider the case that the frequency of vibrating wall is nω1(n = 1, 2, 3, ...) which is a generalization of other works considering only 2ω1, where ω1 is the fundamental-mode frequency of the electromagnetic field in the cavity. For the calculation of time-evolution of quantum fields, w...

Baffled shake flask cultivation of Aurantiochytrium sp. B-072 was carried out at in a glucose-monosodium glutamate mineral medium at different C/N-ratios (30-165) with glucose fixed at 90 g/L. With increasing C/N-ratio, a modest increase in lipid content (60 to 73 % w/w) was observed whereas fat-free biomass decreased but overall biomass showed little variation. FA-profiles were not affected to...

Facing a stochastic market wage, which is independent of their own hiring policy, employers offer contracts specifying fixed wage, revenue share and employment duration. In ongoing employment relations it depends on the treatment whether fixed wages can be only increased or also decreased. Will the uncertainty of the future market wage and less wage flexibility lead to temporary employment? And...

Bu araştırmada Bento ve arkadaşları (2020) tarafından geliştirilen Çocuk-Ergen Mükemmeliyetçilik Ölçeği-Kısa Formunun (ÇEMÖ- KF) Türkçe’ye uyarlanması, geçerlik güvenirlik çalışmasının yapılması amaçlanmıştır. Çalışma; yaşları 10 ile 22 arasında değişen 364 çocuk ergen (110 erkek; 254 kadın) yürütülmüştür. Ölçeğin yapı geçerliği açımlayıcı faktör analizi (AFA) doğrulayıcı (DFA) sınanmıştır. Ölç...
