STEEL RELIEVING CONSTRUCTIONS IN MINING AREAS AS TEMPORARY OR PERMANENT RAILWAY BRIDGES

Attitudes as Temporary Constructions

For the past several years we have investigated the effects of introspection on attitude change. We have found that when people are asked to think about why they feel the way they do about something, they often change their minds about how they feel. People who analyze their reasons have been found to change their attitudes toward such diverse things as political candidates (Wilson, Kraft, We h...

Henna Tattoo: Temporary or Permanent?

Comparison of Design Standards for Steel Railway Bridges

The popularity of steel bridges is increasing in the modern era because of its unmatchable advantages. Engineers are using various national codes to achieve an optimum design. Some of the Asian countries are using their own codes and also American and other country code provisions to achieve better economy and better standards. In this regard the comparison of design codes is relevant. Comparis...

Methods for Better Assessment of Fatigue and Deterioration in Bridges and Other Steel or Concrete Constructions

Large metal and concrete structures suffer by various kinds of deterioration, and accurate prediction of the remaining life is important. This paper informs about two methods for its assessment. One method, suitable for steel bridges and other constructions exposed to fatigue, monitors the loads and damage accumulation using information systems for the operation and the finite element model of ...

Macroeconomic Fluctuations: Demand or Supply, Permanent or Temporary?

We use generalized method of moments to estimate a rational expectations aggregate demand/aggregate supply macroeconomic model for five European economies and the United States. Our aim is to examine whether supply or demand shocks have predominated in these economies during the post-war era, and whether shocks of either type have been primarily temporary or permanent in nature. The estimation ...
