One of the problems in the case of stainless steels is their low corrosion resistance against pitting corrosion in chloride containing environments, thereby leading to severe damage to industries. In this research, the pitting corrosion of 304 austenitic stainless steel was studied in 3.5% NaCl solution at room temperature (25˚C) by performing electrochemical measurements (containing cyclic pol...

an 8-year old boy with polyarthritis and nail involvement is presented in this report. nail involvement in reiter's syndrome is a rare condition that may include painless erythematous nduration of the base of the nail fold; subungual parakeratotic scaling and thickening opacification, ridging of the nail plate.

Sirs, A 12-year-old female presenting with a onemonth history of painful edema of the hands followed by edema of the feet and legs was admitted to our clinic. She had a history of occasional thrombocytopenia (83,000/mcl) since eleven years of age, without markers of autoimmune diseases. Our physical examination revealed pitting edema of her hands and feet and edema of the pretibial region and o...

The critical role of manganese sulphide (MnS) inclusions for the initiation of the short-term growth of pitting or localized corrosion of low carbon steels has long been recognized. Classical results show that pitting probability and pitting severity increases with increased sulphide concentration for low carbon steels as a result of magnesium sulphides acting as local cathodes for initiating p...

Reinforcing steel bars (-12mm diameter and 150mm long) were used in cyclic polarization tests in saturated Ca(OH)z solution and simulated concrete pore solution (SPS) with various levels of sodium chloride addition. Below a limiting chloride level (-O.004M [Cl-] in Ca(OH)z solution and -0.4M [Cl-] in SPS solution), steel was not found to undergo pitting corrosion even if it was polarized to the...

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...

PATIENT Female, 56 FINAL DIAGNOSIS: Thyroiditis - silent Symptoms: Palpitations • pretibial pitting edema • short of breath • sweating MEDICATION - Clinical Procedure: - Specialty: Endocrinology and Metabolic. OBJECTIVE Unknown etiology. BACKGROUND Hyper- or hypothyroidism sometimes causes pretibial myxedema characterized by non-pitting infiltration of a proteinaceous ground substance. Ho...

Stem pitting is a common virus-induced disease of perennial woody plants induced by a range of different viruses. The phenotype results from sporadic areas of the stem in which normal xylem and phloem development is prevented during growth of stems. These alterations interfere with carbohydrate transport, resulting in reduced plant growth and yield. Citrus tristeza virus (CTV), a phloem-limited...

A study was performed to evaluate fault detection effectiveness as applied to gear tooth pitting fatigue damage. Vibration and oil-debris monitoring (ODM) data were gathered from 24 sets of spur pinion and face gears run during a previous endurance evaluation study. Three common condition indicators (RMS, FM4, and NA4) were deduced from the time-averaged vibration data and used with the ODM to ...
