In this study, an attempt was made to minimize the corrosion rate and maximize pitting potential of dissimilar metal welded joints of A387-Gr91/AISI316 steels. Process parameters of the pulsed current gas tungsten arc welding (PCGTAW) including of peak current (P), background current (B), pulse frequency (F), and on time percentage (O) were chosen as the influencing factors on corrosion behavio...

In 1987 we noticed excess adipose tissue in a patient with arm lymphedema and later, objective studies confirmed this clinical finding in patients with non-pitting arm lymphedema following breast cancer. A prospective study was begun in 1993, and its long-term results (15 years) shows overall complete reduction of the excess volume in patients with non-pitting arm lymphedema and that adipose ti...

BACKGROUND Novel immune checkpoint inhibitors have been often utilized for different types of malignancies as salvage therapy with varying success. One obstacle to immune checkpoint inhibitor use is the higher incidence of immune-mediated side effects that can prompt discontinuation of therapy. Remitting seronegative symmetrical synovitis with pitting edema has been described with immune checkp...

Plum bark necrosis stem pitting-associated virus (PBNSPaV) causes the plum bark necrosis stem pitting-associated disease. We obtained the complete genome of a PBNSPaV isolate (PBNSPaV-TA) using small RNA deep sequencing followed by overlapping RT-PCR. To our knowledge, this is the first report of a completed genome of PBNSPaV identified from cherry trees.

Stainless steels have good corrosion resistance in many environments but welding or aging can decrease their resistance. This work focused on the effect of aging time and ultrasonic nano-crystal surface modification on the passivation behavior of 316L stainless steel. In the case of slightly sensitized 316L stainless steel, increasing the aging time drastically decreased the pitting potential, ...

Duplex stainless steel multi-pass welds were made at 0.15 MPa, 0.45 MPa, and 0.75 MPa pressure, simulating underwater dry hyperbaric welding by the flux-cored arc welding (FCAW) method, with welds of normal pressure as a benchmark. The purpose of this work was to estimate the effect of ambient pressure on the microstructure, pitting corrosion resistance and impact toughness of the weld metal. T...

CASE 1 A 74 year old white man presented with an abrupt onset of metacarpophalangeal (MCP) and interphalangeal (IP) joint pains associated with swelling of both hands. He had two hours of morning stiVness but no other joint complaints or history of constitutional symptoms. Past medical history was unremarkable except for diabetes mellitus type 2 treated with oral antidiabetic drugs. Examination...

A previously healthy man, 43 years of age, was referred to the dermatology department with a one-year history of fingernail onychomycosis. His condition was refractory to oral antifungal treatment (terbinafine 250 mg QD for three months). On physical examination, nail pitting and onycholysis affecting seven fingernails was noted (Figure 1A). He also had mild erythematous silvery-white scaly pat...

stress-corrosion cracking (scc) tests were conducted in the near-neutral ph standard solution, ns4, and in an actual soil solution, using four-point bending at a high stress ratio and low frequency conditions very similar to those of operational pipelines. pitting incubation appeared first and then pitting initiated and grew in both solutions although there were many more pits on the specimen t...
