Two-tensor, bimetric (or ‘‘f-g’’) gravity (BMG) was born as the fusion of the strong-interaction resonances of the 1960s (specifically that of a massive spin 2 field) with general relativity’s (GR) massless metric [1]. The idea was to join the two symmetrically by giving each its own Einstein-Hilbert action, then coupling the two resulting ‘‘spaces’’ through a nonderivative ‘‘mass term’’ that n...

Objective: We present our experience of buccal mucosa substitution urethroplasty in all segments the Anterior urethra, as mucosal graft (BMG) is now recognized tissue choice for single-stage reconstruction bulbar urethral strictures. Patients and methods: Twenty-five patients underwent BMG at center between January 2015 2019: 18 a dorsal on lay (pendulous, bulbous), 2 ventral onlay (1 pendulous...

The influence of crystallinity on the electrocatalytic activity complex alloys requires further clarification to optimize their properties. In this work, properties additively manufactured Fe-based bulk metallic glasses (BMG), namely, toward oxygen evolution reaction are studied in alkaline media. Laser powder bed fusion (PBF-LB/M) is applied fabricate electrodes with different numbers glass-fo...

Here, we successfully welded two bulk metallic glass (BMG) materials, Zr51Ti5Ni10Cu25Al9 and Zr50.7Cu28Ni9Al12.3 (at. %), using a liquid-solid joining process. An atomic-scale metallurgical bonding between two BMGs can be achieved. The interface has a transition layer of ~50 μm thick. The liquid-solid joining of BMGs can shed more insights on overcoming their size limitation resulting from thei...

Shear deformations of Cu57Zr43 bulk metallic glass (BMG) model systems are performed using molecular dynamics simulation. The results suggest that both the hydrostatic stress and the stress normal to the shear plane should affect the shear response (modified Mohr–Coulomb yield criterion). We see shear localization and shear band nucleation in both a small system of 2000 atoms, and large systems...

The use of buccal mucosa graft urethroplasty (BMGU) for bulbar urethral strictures has gained widespread popularity since the first report in 1996. Over the last two decades, there have been many modifications in the surgical technique. This, along with better understanding of urethral anatomy, has allowed the BMG to become the 'gold standard' in urethral substitution. The present article revie...

In this research, a thermodynamic study is executed for multi-generation hybrid renewable energy system (MG-HRES) off-grid supply to rural settlement in Katsina state, Nigeria. the system, downdraft biomass gasifier (BMG), syngas electrical engine (SGE) attached with an absorption refrigeration and wind turbine generator are integrated relieve variability deliver three useful outputs. The which...

Ti-2.5Zr-5.0Hf-37.5Cu-7.5Ni-1.0Si-5.0Sn (at.%) BMG has been successfully manufactured in amorphous powder with a size of about 25 μm (D50). Using this powder, Ti-based was by an additive manufacturing process based on laser bed fusion (LPBF) technique. In 3D printing processes using powders, it is necessary and important to understand the crystallization behavior due difference energy density a...
