Background: Since sponge iron is the main feed of steel furnaces for the production of crude steel, especially in electric arc furnaces, the production of quality sponge iron is one of the concerns of the steel industry.The reduction process, which is the conversion of pellets into sponge iron using reduction gases, has been used in Iran for many y
It is safe to say that over the past decade, no region in the world as much as the Middle East and North Africa has been involved with rapid political developments, unrest and instability.The beginning of a cycle of mass protests and instability in the aftermath of the Arab Spring is just one of those cases.The main purpose of the present research
The proliferation of specific lymphocytes is the central tenet of the clonal selection paradigm.Antigen recognition by T cells triggers a series of events that produces expanded clones of differentiated effector cells.TCR signaling events are detectable within seconds and minutes and are likely to continue for hours BODY WASH and days in vivo.Here,
Activity in the human temporoparietal junction and inferior frontal gyrus is hypothesized to underlie stimulus-driven, or bottom-up attention reorienting.Demanding tasks require focused attention, and as task difficulty increases, activity suppression in the ventral network correlates positively with task performance, an Welding Helmet Accessory ef
Abstract Background Research ethics and the measures deployed to ensure ethical oversight of research (e.g., informed consent forms, ethics review) are vested with extremely important ethical and practical goals.Accordingly, these measures need to function effectively in real-world research and to follow high level standards.Methods Welding Helmet
