In situ monitoring of the melt pools in laser powder bed fusion (LPBF) has enabled elucidation process phenomena. There been an increasing interest also using pool to identify anomalies and control quality manufactured parts. However, a better understanding variability relation incidence internal flaws are necessary achieve this goal. This study aims link distributions dimensions signal charact...

The envelope glycoprotein gp41 mediates the process of membrane fusion that enables entry of the HIV-1 virus into the host cell. Strong lipid affinity of the ectodomain suggests that its heptad repeat regions play an active role in destabilizing membranes by directly binding to the lipid bilayers and thereby lowering the free-energy barrier for membrane fusion. In such a model, immediately foll...

PURPOSE To report a case of corneal melting in a patient with fornix foreshortening being treated with reformulated generic diclofenac. METHODS Case report. RESULTS An asymptomatic 76-year old man presented with central corneal melting while being treated with reformulated generic diclofenac. This formulation did not contain the vitamin E derivative, tocophersolan, which has been felt to co...

We present the case of a young male that suffered from fungal corneal abscess and corneal melting. The patient was treated successfully by corneal cross-linking. Taking into account our experience from this case, we offer to consider corneal cross-linking as a therapeutic option in cases of fungal keratitis.

Composition, mean pressure, mean melt fraction, and crustal thickINTRODUCTION ness of model mid-ocean ridge basalts (MORBs) are calculated Comparison of observed basalt compositions with the using MELTS. Polybaric, isentropic batch and fractional melts predictions of polybaric mantle melting models places from ranges in source composition, potential temperature, and final important restrictions...

Laser powder bed fusion (LPBF) is an additive manufacturing technique that prints objects layer-by-layer by selectively melting powders using a focused laser. The mechanical properties of LPBF parts are affected processing parameters influence the flow within melt pool. Marangoni convection surface tension dependent mass transfer process from region lower to higher tension, influenced temperatu...

Abstract The MEMOS-U physics model, addressing macroscopic melt motion in large deformation and long displacement regimes, its numerical schemes are presented. Discussion is centred on the shallow water application to metallic melts induced by hot magnetized plasmas, where phase transitions electromagnetic responses pivotal. of boundary conditions with their underlying assumptions analysed sens...

The exact amount of vaporization losses and melt layer thickness resulting from a plasma disruption are very important to fusion reactor design and lifetime. Experiments using ion or electron beams to simulate the disruption effects have different environments than the actual disruption conditions in fusion reactors. A model has been developed to accurately simulate the beam-target interactions...

Laser powder bed fusion (LPBF) has made significant progress in producing solid and porous metal parts with complex shapes geometries. However, LPBF produced often have defects (e.g., porosity, residual stress, incomplete melting) that hinder its large-scale industrial commercialization. The process involves heat transfer fluid flow, the melt pool is a critical component of process. stability f...

This study investigates the possibility of correlating specimen property to part performance for laser beam powder bed fusion (LB-PBF) additive manufacturing by altering process parameters in order create similar thermal histories experienced during fabrication. In particular, effects scanning speed on LB-PBF 17-4 precipitation hardening (PH) stainless steel (SS) parts with different geometries...
