Nitrification, previously shown to occur in the stream under study, ensued only when the stream received heated (28 degree C or above) discharges and was negligible when water temperatures were 17 degree C or lower. The most probable number os ammonium oxidizer in stream bed sediments exceeded intrite oxidizers by ratios of 43:1 to 1,113:1, and the average(More)
This work seeks to support the validation of large eddy simulation models used to simulate fire suppression. The emphasis in the present study is on the prediction of flame extinction and the prevention of spurious reignition using a fast chemistry, mixing-controlled combustion model applicable to realistic fire scenarios of engineering interest.

We present two cases of reactivation of Hand-Schüller-Christian disease or multifocal eosinophilic granuloma 6 and 13 years after discontinuation of systemic therapy. Both patients received oral therapy with methotrexate and prednisone continuing for 2--3 years after the disease was thought to be in remission. Relapses were detected because of disease(More)
Testicular cancer is one of the most common cancers in men between the ages of 15 and 34. Symptoms of testicular cancer vary but can include scrotal nodules or swelling and a sensation of fullness or heaviness of the scrotum, which may be interpreted as pain. Four treatment options are available for testicular cancer: surgery to remove the cancer, radiation(More)
