Abstract The influence of keyhole TIG (K-TIG) welding parameters on the weld geometry and defects a new nickel-based superalloy VDM Alloy 780 alloy were investigated using statistical design experiment, microstructures heat-affected zone (HAZ) fusion (FZ) K-TIG-welded characterized. No cracks are found in FZ HAZ. Travel speed significantly influences minimum width (Wm), face root excess metal, ...

This study aimed to determine the relationship of some metabolic constituents in follicular fluid (FF) with size (FZ) and oocyte diameter (OD) local ewes ovaries (Ovis aries), from September 2021 February 2022 Laboratories Animal Production Department, Al-Musaib Technical College. Two hundred non-pregnant genital organs were collected abattoirs Babylon province carried laboratory within two hou...

To satisfy the design requirements for a hydropneumatic spring damper valve, inlet–outlet pressure drop (ΔP) and axial force on spool (FZ) of valve were investigated using fluid–solid coupling simulations multi-objective optimization, along with effects diameters three internal holes (DA, DB, DC) in ΔP FZ. First, meshed computational fluid dynamics model was established based its geometric stru...

Abstract Zn–Al–Mg coating galvanized steel in resistance spot welded (RSW) different configurations of DC51D was investigated to illustrate the nugget evolution process and mechanical properties joints. Results show that microstructure joints can be divided into zone (FZ), heat-affected (HAZ), base metal (BM). FZ composed lath martensite. The average hardness value weld joint 110 HV 0.2 while u...

background and aim: auditory p300 is an event-related potential. cognitive factors like attention are involved in the generation of p300. it seems that normative variation of p300 is necessary for clinical purposes. thus, the current study was designed to establish preliminary normative variation of p300 amplitude and latency at fz and cz sites in adults. methods: this cross-sectional study was...

Members of the Frizzled (Fz) family of seven-pass transmembrane receptors are required for the transduction of both Wnt-Fz/beta-catenin and Fz/planar cell polarity (PCP) signals. Although both pathways transduce signals via interactions between Fz and the cytoplasmic protein Dishevelled (Dsh), each pathway has specific and distinct effectors. One explanation for the pathway specificity is that ...

In this study, an external transverse magnetic field was used to assist laser-metal inert gas (MIG) hybrid welding of Ti-6Al-4 V (TC4). The microstructure and mechanical properties, such as microhardness tensile properties the weld joints, under (EMF) a reference joint without EMF were investigated. results showed that laser-arc interaction zone (LAIZ) heat-affected (HAZ) expanded, laser fusion...

High-dosage buprenorphine (BUP) consumed concomitantly with benzodiazepines (BZDs) including flunitrazepam (FZ) may cause life-threatening respiratory depression despite a BUP ceiling effect and BZDs' limited effects on ventilation. However, the mechanism of BUP/FZ interaction remains unknown. We hypothesized that BUP may alter the disposition of FZ active metabolites in vivo, contributing to r...
