This group of paintings portrays the beauty and strength frontline clinicians in a hectic emergency room during COVID-19 pandemic. Head-to-toe personal protective equipment covers their fear. Vibrant colors strange perspectives help question reality through which they patients lived.

Electroceramic thick films are 2D (planar) structures that, in their simplest form, consist of a substrate, a bottom electrode, a ceramic film and a top electrode, with the thickness of an individual layer being typically between 1 and 100 μm. The processing of thick films is similar to the processing of bulk ceramics, i.e., it involves powder synthesis, shaping and sintering. The major differe...

The recent focus on diversity in themanagement literature takes on special urgency in the context of human services organizations. Human services organizations have traditionally served a wide array of communities with a high representation of diverse, disadvantaged, and oppressed groups. This diversity has not typically been mirrored in the workforce of those organizations. A recent study of a...

Studies on surface analysis of carbon steel protected from corrosion in low chloride and nearly neutral aqueous environment by a synergistic mixture containing N,N-bis(phosphonomethyl) glycine (BPMG), zinc ions and citrate ions are presented. The effect of addition of citrate to the binary system, BPMG-Zn, is quite significant and is well explored through various studies. The surface protective...

Protective layers typically act in a passive way by simply separating two sides. Protection is only efficient as long as the layers are intact. If a high level of protection has to be achieved by thin layers, complementary measures need to be in place to ensure safety, even after breakage of the layer-an important issue in medical applications. Here, we present a novel approach for integrating ...

Inconel 713C is a nickel-based superalloy usually considered as material of poor weldability due to its susceptibility hot cracking in the heat-affected zones. Cold spray, solid-state deposition technology that does not involve melting, can be proposed methodology deposit for surface enhancement other target components. In this study, coating was deposited on 718 substrate with high-pressure co...

The corrosion phenomenon affects several low carbon steel structures leading to excessive expenditure on coatings and other alternatives. However, the used usually contain compounds that pollute environment. Therefore, environmentally friendly, economical transparent or films have been developed. sol-gel method is a reliable way for development of anticorrosive films, as case alumina silica fil...

according to development of displacement–performance based design, there are some studies on different structures which most of them are about regular plan structures. in this research has been tried to review the frame steel structures designed based on 2800 standard of iran to achieve the designed structures performance level to find how much function levels it covers in earth quake. to show ...

PURPOSE To quantify the clinically observed dose enhancement adjacent to cranial titanium fixation plates during post-operative radiotherapy. METHODS Irradiation of a titanium burr hole cover was simulated using Monte Carlo code MCNPX for a 6 MV photon spectrum to investigate backscatter dose enhancement due to increased production of secondary electrons within the titanium plate. The simulat...
