Two cores from a marine diesel engine oil cooler were received for analysis to investigate the cause of failure via leaking. Results indicate that the cooler core failed due to pitting corrosion initiated on the interior (oil side) at the edge of the fins.

Two blade samples of a cracked ******************* centrifugal blower impeller blade was submitted for metallurgical analysis of the cracks. The cracks in the submitted blade samples were found to have initiated at corrosion pits on the leading edge of the blades.
Breast cancer patients often suffer menopausal symptoms, which include vaginal dryness. This distressing symptom is often treated with topical estrogen or progesterone creams; however, there remains a concern about systemic absorption of estrogen and its effect on breast cancer. In a group that is treated with tamoxifen, it would appear that the systemic affect would be negated by the tamoxifen's anti-estrogen blockade but the question remains hotly debated.

The ongoing research and development of new anticoagulant/antiplatelet drugs deserves special attention in the evaluation and management of patients presenting for surgery.
Several concentrating still condenser tubes exhibiting pitting were received to determine the cause of pitting. Results indicate the tubes pitted initially from the inner diameter (ID) surface due to microbiological corrosion (MIC). MIC pitting initiated preferentially at the tube seam weld. Additional ID surface pits and significant pit enlargement of MIC pits due to chloride pitting were also observed. The chlorine is likely remains from the hydrochloric cleaning process
In various industries there are valve applications where the standard valves used do not function satisfactorily. When scale is formed on the moving elements of ball valves or gate valves the consequence is either blocking of the valve movement or damage to the valve seats and consequent leaking through the valves
After 60 years of availability of antibiotics, surprisingly little is known about their role in obstructive airway diseases. Areview of antibiotic therapy will necessarily involve a discussion of the role of bacterial infection in asthma and chronic obstructive pulmonary disease
