Using turbulent MHD simulations (magnetic Reynolds numbers up to≈ 8000) and Hinode observations, we study effects of turbulence on measuring the solar magnetic field outside active regions. Firstly, from synthetic Stokes V profiles for the FeI lines at 6301 and 6302 Å, we show that a peaked probability distribution function (PDF) for observationally-derived field estimates is consistent with a ...

Root and shoot branches are major determinants of plant form and critical for the effective capture of resources below and above ground. These branches are often maintained at specific angles with respect to gravity, known as gravitropic set point angles (GSAs). We have previously shown that the mechanism permitting the maintenance of non-vertical GSAs is highly auxin-dependent and here we inve...

The causes of bilateral asymmetries during able-bodied gait are unclear. These asymmetries may represent a form of functional asymmetry, which has been defined as a consistent task discrepancy between the two lower limbs. According to this theory, the non-dominant lower limb contributes more to support, while the dominant lower limb contributes more to forward propulsion. Impulses due to vertic...

Abstract The aim of this research is to review the literature for influence thickness and shape cervicalmargins on strength posterior monolithic zirconia crowns. Studies assess fracture resistance crowns with different types cervical margins, published from 2014 2020, were searched using electronic database PubMed Google Scholar following keywords: “monolithic zirconia,” “translucent,” “shoulde...

background and aims. plasma rich in growth factors (prgf) is a concentrated suspension of growth factors, which is used to promote periodontal tissue regeneration. the aim of this randomized, controlled, clinical trial was to evaluate of the treatment of grade ii mandibular molar furcation involvement using autogenous bone graft with and without prgf. materials and methods. in this double-blind...

PURPOSE To quantify long-term changes in stromal collagen ultrastructure following penetrating keratoplasty (PK), and evaluate their possible implications for corneal biomechanics. METHODS A pair of 16 mm post-mortem corneo-scleral buttons was obtained from a patient receiving bilateral penetrating keratoplasty 12 (left)/28 (right) years previously. Small-angle x-ray scattering quantified col...
