The Kármán–Howarth theorem is derived for the Lagrangian averaged Navier-Stokes alpha (LANS−α) model of turbulence. Thus, the LANS−α model’s preservation of the fundamental transport structure of the Navier-Stokes equations also includes preservation of the transport relations for the velocity autocorrelation functions. This result implies that the alpha-filtering in the LANS−α model of turbule...

alpha thalassemia (α-thal) is relatively common worldwide. most carriers are defective in either one or two alpha globin genes out of four functional ones, with deletions being more common than point mutations. the hematologic features are very important for the selection of the appropriate molecular tests while determining the genotype. the aim of this study was to compare hematologic features...

background: alpha thalassemia (α-thal) is one of the most common hemoglobinopathies worldwide. the aim of this study was to investigate the spectrum of α-thal mutations among premarital baluch couples in southeastern iran. subjects and methods: we assessed 1215 individuals by multiplex gap polymerase chain reaction (gap-pcr) and amplification refractory mutation system (arms-pcr). results: of t...

The alpha-helix to beta-sheet transition (α-β transition) is a universal deformation mechanism in alpha-helix rich protein materials such as wool, hair, hoof, and cellular proteins. Through a combination of molecular and theoretical modeling, we examine the behavior of alpha-helical coiled-coil proteins with varying lengths under stretch. We find that the occurrence of the α-β transition is con...

Of alpha-amylases and other starch-digesting enzymes from bacteria and plants.ess was supplemented with bacterial and fungal amylases or scalded flour. Immunochemical characteristics of alpha-amylase sensitization.Alpha-amylase production and its activity was compared in two different. Bacterial amylases are resistant to high temperatures, they can active in wide pH.fungal amylascs lowest, liqu...

Background and Aims: Interferon alpha is an effective cytokine in viral infections, where it has various roles in immune function. The use of this antiviral agent in the treatment of viral infections and even cancers is common, although, the beneficial effects of this antiviral agent in high doses can be associated with side effects that limit its use. In this project, we tried to investigate t...

We study the relaxation of local ferromagnetic order in transverse field quantum Ising chain with power-law decaying interactions \sim 1/r^\alpha ∼1/rα . prepare system GHZ state and ti...

Helium( 4 He, or α)is the second most abundant element in observable Universe. The α-particle induced reactions such as(α, γ), (α, n) and p) play a crucial role nuclear astrophysics, especially for understanding stellar heliumburning. Because of strong Coulomb repulsion, it is greatly hindered to directly measure cross sections these α-capture at energies. Alpha-cluster transfer reaction powerf...
