Experimental Study of Steel-Aluminum Joints Made by RSW with Insert Element and Adhesive Bonding.

This work focuses on joining steel to aluminum alloy using a novel method of joining by resistance spot welding with an insert element based on anticorrosive steel in combination with adhesive bonding. The method aims to reduce the formation of brittle intermetallic compounds by using short welding times and a different chemical composition of the insert element. In the experiment, deep-drawing low-carbon steel, HSLA zinc-coated steel and precipitation-hardened aluminum alloy 6082 T6 were used.

Automated measurement method and tool of glomerular filtration rate using triphasic helical computed tomography images.

Objectives: To introduce an automated method to perform computed tomography-based glomerular filtration rate (CT GFR) measurement using the 2-point Patlak plot technique and triphasic helical CT images. We also evaluated the correlation between our automated method and the manual measurement results, as well as the results from cystatin C.

Methods: The present study included 25 patients without an acute renal disorder.

Decreased incidence of prostate cancer with selenium supplementation: results of a double-blind cancer prevention trial.

Objective: To test if supplemental dietary selenium is associated with changes in the incidence of prostate cancer.

Patients And Method: A total of 974 men with a history of either a basal cell or squamous cell carcinoma were randomized to either a daily supplement of 200 microg of selenium or a placebo. Patients were treated for a mean of 4.

Unusual complications of the vacuum erection device.

Objectives: The vacuum erection device (VED) is usually well tolerated and very effective for patients with erectile dysfunction. When used correctly, VEDs carry low morbidity and few recognized complications. We report on 5 patients who developed unusual complications associated with VED use, including two previously unreported complications of urethral bleeding and capture of scrotal tunica within the penile shaft.
