this work presents a simulation approach to the design and economic evaluation of fuel oil hydrotreating processes for control of so2 and nox emission in an iranian steam power plant. minimum amount of required fuel oil desulphurization was calculated from the limit of so2 emissions of power plants in two different scenarios based on (i) european and (ii) iranian so2 emission standards. based o...

this study investigated the effects of land size and two leased and private farming systems of machinery on economic efficiency and factors such as total production cost per hectare (ratio of total cost of agricultural inputs and operations to farm size), total income (ratio of product and byproduct value to farm size), yield (ratio of crop production to farm size) and degree of mechanization f...

One ofthe major difficulties in controlling software development project cost overruns and schedule delays has been developing practical and accurate software cost models. Software development could be modeled as an economic production process and we therefore propose a theoretical approach to software cost modeling. Specifically, we present the Minimum Software Cost Model (MSCM), derived from ...

AIMS This study aims to review the economic cost of childhood (0-18 years) unintentional injuries (UI) and focuses upon comparing the cost burden between developing and developed countries. METHODS Articles were selected from PUBMED using the search words "Economic Cost", "Unintentional injuries" and "Children". Nine articles were selected. RESULTS Studies in China focused upon cost to hosp...

Argues that it is unrealistic to expect the net benefit of economic globalization to be represented by a single monetary figure because its consequences are diverse and several of its consequences are uncertain. The benefits of economic globalization are accessed in terms of its possible impact on the level of global production and exchange of commodities. Both static and dynamic analysis are c...

This paper aims at positioning producer cooperatives within the Transaction Cost Economics theory, one of the most cited and prolific theories on management studies. To accomplish this goal, I will answer the questions what is a cooperative, which transactions producer cooperatives regulate, under which market conditions they operate, and where are the boundaries for such organizations. This pa...

We subject claims about the benefits of activity-based costing systems to the scrutiny of analytical models incorporating rational behavior by users of product costing systems. We find that a monopolist Is almost always strictly better off using multiple cost drivers as in an activity-based costing (ABC) system even when the system makes measurement errors in assigning overhead costs to activit...

Dengue, endemic in Puerto Rico, reached a record high in 2010. To inform policy makers, we derived annual economic cost. We assessed direct and indirect costs of hospitalized and ambulatory dengue illness in 2010 dollars through surveillance data and interviews with 100 laboratory-confirmed dengue patients treated in 2008-2010. We corrected for underreporting by using setting-specific expansion...

OBJECTIVE To calculate the costs of suicide in Ireland. METHOD The paper identifies all episodes of suicide in Ireland in 2001 and 2002, and projects the economic costs arising from these episodes over subsequent years. All prices have been converted to 2001 Euros. Both direct and indirect costs were calculated. Indirect costs included both the cost of lost output and human costs. RESULTS T...
