Abstract This paper provides an overview of research on core from Oman Drilling Project Hole BT1B and the surrounding area, plus new data calculations, constraining processes in Tethyan subduction zone beneath Samail ophiolite. The area is underlain by gently dipping, broadly folded layers allochthonous Hawasina pelagic sediments, metamorphic sole ophiolite, Banded Unit peridotites at base mant...

A new analytical study performed to investigate the effect of the temperature difference between gas and particle in propagation of the spherical flames. The combustible system is containing uniformly distributed volatile fuel particles in an oxidizing gas (Air) mixture. The model includes evaporation of volatile matter of dust particles to known gaseous fuel (methane) and the single-stage reac...

We study the slow neutron capture process (s process) in Asymptotic Giant Branch (AGB) stars using three different stellar evolutionary models computed for a 3 M⊙ and solar metallicity star. First we investigate the formation and the efficiency of the main neutron source: the C(α,n)O reaction that occurs in radiative conditions. A tiny region rich in C (the C pocket) is created by proton captur...

Cytogenesis in the cat retina was studied using tritiated (3H) thymidine autoradiography and nuclear stains. Three zones of cell division were recognized. In the first zone cell cleavage occurs at the outer limiting membrane. The distribution of these mitotic figures is uniform as early as an embryonic age of 29 days (E29) until E50. At about E50 a "cold spot", made apparent by the absence of m...

Context. To investigate the physical nature of the 'nucleated instability' of proto giant planets, the stability of layers in static, radiative gas spheres is analysed on the basis of Baker's standard one-zone model. Aims. It is shown that stability depends only upon the equations of state, the opacities and the local thermodynamic state in the layer. Stability and instability can therefore be ...

The shoot apicalmeristem (SAM) acts as a reservoir for stem cells. The central zone (CZ) harbors stem cells. The stem cell progenitors differentiate in the adjacent peripheral zone and in the rib meristem located just beneath the CZ. The SAM is further divided into distinct clonal layers: the L1 epidermal, L2 sub-epidermal and L3 layers. Collectively, SAMs are complex structures that consist of...

Ischemic stroke is the third most common cause of death in humans, requiring further studies to elucidate its pathophysiological background. One potential mechanism to increase oxygen delivery to the affected tissue is induction of angiogenesis. The most potent proangiogenic factor is VEGF. For this reason, our study investigated immunohistochemically VEGF reactivity in different cellular brain...
