Study the corrosion behavior of low carbon steel weldments immersed in tap water [PDF]

open access: yesAl-Qadisiyah Journal for Engineering Science
Corrosion is one of the main sources of failure for metals and alloys, thus it is a major engineering problem. Engineers must consider the corrosion of metals in different environments when designing engineering parts. Metals tend to corrode in different

Investigation of joining properties of AA 5083 material in MIG and TIG weldings

open access: yesCumhuriyet Science Journal, 2021
AA 5083 Aluminum alloys begin to be replaced steels in automobiles, ships, and high-speed-trains by providing reduced energy consumption and low carbon emissions thanks to their low densities, good weldabilities, and high corrosion resistance. During the

Pathophysiology of sepsis‐induced cholestasis: A review

open access: yesJGH Open, 2022
Sepsis is a critical condition resulting from the excessive activation of the inflammatory/immune system in response to an infection, with high mortality if treatment is not administered promptly. One of the many possible complications of sepsis is liver

Numerical Analysis of Metal Transfer Process in Plasma MIG Welding

open access: yesMetals, 2022
In plasma MIG welding, inert gas introduced from the torch nozzle is ionized in the upstream region of the MIG arc, which is termed “plasma”. This study aims to clarify the effect of the plasma on the metal-transfer process in the plasma MIG welding ...

Use of inundated lakeshore vegetation by Cichlids for reproduction in Lake Kinneret (Israel)

open access: yesFrontiers in Marine Science, 2015
The collapse of the Sarotherodon galillaeus fishery in Lake Kinneret, from a mean annual catch of ~300 tons, to less than 10 tons in 2008 may indicate an imbalance between reproduction and mortality of the species.

Deliberate Establishment of Asymptomatic Bacteriuria—A Novel Strategy to Prevent Recurrent UTI

open access: yesPathogens, 2016
We have established a novel strategy to reduce the risk for recurrent urinary tract infection (UTI), where rapidly increasing antibiotic resistance poses a major threat. Epidemiologic studies have demonstrated that asymptomatic bacteriuria (ABU) protects
