Laser clad coating’s susceptibility to cracking is extremely high due the brittleness of material itself and enormous residual stress caused by rapid heating cooling. In order relieve stress, a series Fe-based amorphous-Cu composite coatings were fabricated on 20 steel using laser processing. The effects copper addition phase composition microstructure evolution then investigated. as-prepared c...

nuclear cross sections that determine core multiplication strongly depend on core temperature (e.g., the doppler, moderator density effects etc). on the other hand, since this heat is generated by the neutron flux in the reactor core, the temperature distribution in the core will depend heavily on its neutronic behavior. fuel centerline temperature could be the limiting constraint on reactor po...

Partial dilution of clad powder and the substrate to form a new protective layer is called as cladding. The present article focuses on development novel surface modification technique for better resistance wear/erosion using microwaves source heat. Clads MoCoCrSi/ WC-Co were produced austenitic stainless steel (SS-316) microwave irradiation techniques. Composite clads established by irradiating...

In this paper, an analytical model based on Modified Slab Method is presented for rolling of clad sheet or double-layers in which the two layers are bounded prior to rolling. This model considers the general case of asymmetrical rolling due to unequal &#10surface speed, different contact friction, roll diameters, flow stress, and thickness ratios of the two layers. Using this model, rolling par...

PurposeSurvival after lung transplantation (LT) is hampered by the development of chronic allograft dysfunction (CLAD). There no treatment available to reverse CLAD once diagnosed, but early intervention could modify progressive function decline. Thus, biomarkers are need for detection CLAD. High levels donor derived cell-free DNA (ddcfDNA) have been described precede acute cellar rejection and...

AIM To assess the prevalence of vitamin D deficiency in burka-clad pregnant women and to study feto-maternal outcome in these women. METHODS 200 pregnant burka-clad women of 18-40-year age group irrespective of the period of gestation were recruited from the ANC OPD/ward of Kasturba hospital, and their vitamin D levels were estimated. Patients were categorized into vitamin D deficient, vitami...

OBJECTIVE There is growing interest in using closed-loop anesthetic delivery (CLAD) systems to automate control of brain states (sedation, unconsciousness and antinociception) in patients receiving anesthesia care. The accuracy and reliability of these systems can be improved by using as control signals electroencephalogram (EEG) markers for which the neurophysiological links to the anesthetic-...

Chronic lung allograft dysfunction (CLAD) is, in one sense, a term without a true consensus definition, although its common usage in the field of lung transplantation implies a base understanding throughout the community that it describes a lung allograft that does not work (well) [1]. There appears to be general agreement that CLAD most commonly occurs in a time-dependent fashion after transpl...

Abstract Interfacial structure greatly affects the mechanical properties of laminated plates. However, critical material that impact interfacial morphology, appearance, and associated bonding mechanism explosive welded plates are still unknown. In this paper, same base plate (AZ31B alloy) different flyer metals (aluminum alloy, copper, stainless steel) were used to investigate morphology struct...
