Since the authors' initial experience in the surgical management of bronchogenic carcinoma in 1956, more than 40 years have passed. The purpose of this report was to review the authors' data and compare the results by decade (1956-1966; 1967-1976; 1977-1986; and 1987-1996) in order to assess the changing patterns in bronchogenic carcinoma. A total of 1,597 thoracotomies have been performed. Bet...

Bangladesh currently has a population approaching 150 million and will add another 100 million before stabilizing, unless fertility can soon drop below replacement level. This level of fertility decline will require a change in marriage patterns, which have been minimal so far, even with increasing female schooling.

The findings are a reminder that equity investments are risky even over longer time periods, and investors should take this into consideration when making portfolio choices.

This article describes refinements to an instrument for determining the viscoelastic properties of a solid material isothermally, with a single apparatus, over 10 decades of time and frequency. Torque is applied electromagnetically to a specimen fixed at one end. Specimen deformation is determined via a laser beam reflected from the other end upon a split diode detector. Phase resolution is imp...
