PURPOSE To estimate the cost-effectiveness of detecting colorectal polyps with computed tomographic colonography (CTC) and subsequent polypectomy with primary colonoscopy (CC), using CC as the alternative strategy. MATERIAL AND METHODS A marginal analysis was performed regarding 103 patients who had had CTC prior to same-day CC at two hospitals, H-I (n = 53) and H-II (n = 50). The patients we...

this study tries to codify a proper mathematical model which can be predict the costs of repair and maintaining the tractors as precisely as possible for three common models of tractors in shahid beheshti cultivation firm in andimeshk-ahvaz road of dezfoul. studied tractors include: newhland tm155 tractor which is chosen from the most perfect file of 10 tractor machines and jandier tractor-3140...

We address three questions: (i) Can classical models be reconciled with the fact that many crises are marked by high rates of depreciation and small increases in seignorage revenue? (ii) What are the implications of different financing methods for post-crisis rates of inflation and depreciation? (iii) How do governments pay for the fiscal costs associated with currency crises? To study these qu...

In this paper we extend the Lucas (1988) endogenous growth model to include sector-specific external effects and depreciation in both sectors. We derive analytically, the restrictions on the parameter space that are necessary and sufficient for the existence of balanced growth paths and equilibria. We demonstrate that in contrast to the original model, with the addition of an external effect an...

This paper presents estimates of the impact of exchange rate movements on the industry-level price of investment goods using a panel of OECD countries. An exchange rate depreciation (appreciation) causes a significant rise (fall) in the prices of the investment goods used by most industries, but the magnitude of this effect differs greatly across sectors. A currency depreciation causes a strong...

One of the striking characteristics of the recent currency crises in East Asia is the sharp reductions in output that followed depreciations. This paper draws on an earlier literature on contractionary depreciations to motivate an empirical model of the relationship between exchange rate and output fluctuations in a panel of six East Asian economies. There is evidence of a negative relationship...

Previous studies have estimated the "human capital depreciation" of women re-entering the work force after voluntary, lengthy interruptions. Those studies have found reduced real wages and furthermore the decrease is positively related to the length of the interruption. Upon re-entry, however, real wages grow rapidly as human capital is restored. This paper develops a model of the wage historie...

The demand for electricity is currently growing rapidly. In accordance with the government's policy to optimize use of renewable energy sources, including water, by constructing a hydroelectric power plant. study potential utilization Batang river flow aimed at how much optimum electric there in Merangin as hydropower results calculation Kerinci PLTA show that electrical can be generated 366.27...

This article is a research on the economic and financial role of depreciation. Depreciation seen as recognition decrease in value an asset resulting from use, time, change technique or anything else. The depreciation represents difference between its gross net book value. difficulties measuring this lead to spread over probable lifetime goods normally depreciable according plan. If current sign...

A number of studies in the U.S.A. and mainland Europe have described the costs of fibreoptic tracheal intubation. However, no such data from the UK appear available. We performed a cost assessment of fibreoptic intubation, using re-usable (various devices from Olympus, Acutronic and Karl Storz) and single-use (Ambu aScope) fibrescopes, at the Queens Medical Centre, Nottingham, U.K., between 1 J...
