Abstract For the growth of low-defect crack-free GaN heterostructures on large-area silicon substrates, compositional grading AlGaN is a widely adapted buffer technique to restrict propagation lattice-mismatch induced defects and balance thermal expansion mismatch-induced tensile stress. So far, consolidation design strategy such step-graded buffers has been impaired by incomplete understanding...
Background and Aims: It is important to use intracanal medicaments in teeth with necrotic pulp. Calcium hydroxide is the intracanal medicament of choice in such cases. Also, Mineral Trioxide Aggregate (MTA) is a suitable root canal filling material because of its favorable characteristics. MTA can be used in some cases where calcium hydroxide is used. The purpose of this study was to evaluate t...
Objective(s): The aim of this study was to explore the accuracy of thyroid to background uptake ratio (UR) in the evaluation of 99mTc-pertechnetate thyroid uptake (TcTU) and establishment of an improved algorithm. Methods: This study was conducted on the thyroid images of 322 patients with thyroid diseases and 67 controls. For the purpos...
Abstract Critical site percolation on the triangular lattice is described by Yang–Baxter solvable dilute A 2 ( stretchy="false">) loop model with crossing par...
a factorial experiment based randomized complete block was conducted in order to investigation of two rice (oryza sativa l.) genotypes responses for na+, k+, ca2+, mg2+, clˉ, mn2+, p and total soluble sugars accumulation and compartmentation in leaves 3, 4, 5 and 6 to salt stress. in estimation of the simple correlation between traits, dry weight was negatively correlated with na+ and clˉ. the ...
