Copper Pitting and Brass Dezincification: Chemical and Physical Effects
OBJECTIVES: The key hypothesis of this project was that both chemical and physical factors associated with real plumbing systems may influence copper pitting and brass dezincification corrosion, and thus the project was aimed at better understanding these factors. In addition to a comprehensive review of the literature on brass dezincification in potable water systems, experimental work was und...
متن کاملPitting oedema in hypothyroidism.
A 38 yrs old female admitted generalised swelling, puffiness of face and coarsening of features for six months. Examination revealed obesity (BMI 34.7 kg/m) with pitting pedal oedema (Figs, 1,2), normal JVP and delayed relaxation of ankle jerks. Rest of general physical examination and systemic examination was normal. On investigation, haemogram, urine examination, X-ray chest, echocardiography...
متن کاملEffect of Deformation-Induced Defects on the Microstructure and Pitting Corrosion Behavior of Al-Ag Alloy
In this study, a wide range of combined ageing treatments and cold work deformations in the Al 4.2 wt% Ag alloy matrix were proposed, aiming to investigate the effect of defects such as precipitates (Ag2Al plates) and dislocations on the mechanical and electrochemical behavior of Al–4.2 wt% Ag alloys. Further reductions of thickness from 10 to 60%, decreases the mean size of Ag2...
متن کاملPolyarthritis and pitting oedema.
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...
متن کاملNail pitting and onycholysis.
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...
