Invasions of nonnative species such as zebra mussels can have both ecological and economic consequences. The economic impacts of zebra mussels have not been examined in detail since the mid-1990s. The purpose of this study was to quantify the annual and cumulative economic impact of zebra mussels on surface water-dependent drinking water treatment and electric power generation facilities (where...

This paper takes a 2021 Argentine case to show the atmospheric and economic impacts of using LNG fueled dredgers in second largest worldwide operation its kind about start Rio de la Plata. From emissions point view, (Liquified Natural Gas) would reduce 23%, mainly those (NOx, SOx PM) affecting coastal population health. The use BioLNG 99% (60,000 Tons/yr), including as well planetary impact CO2...

historically, turkish-russian relations have been cold and distant. during the cold war, the two former rivals viewed each other with hostility. after the fall of the ussr and in the early 1990s, the grounds were paved for the improvement in the bilateral ties. even though the two states have different military and security concerns, they have established closer relations in economic and trade ...

OBJECTIVES We examined the effects of sprawl, or conventional development, versus managed (or "smart") growth on land and infrastructure consumption as well as on real estate development and public service costs in the United States. METHODS Mathematical impact models were used to produce US estimates of differences in resources consumed according to each growth scenario over the period 2000-...

To estimate cost-effectiveness of routine and catch-up vaccination of Canadian children with seven-valent pneumococcal conjugate vaccine, a simulation model was constructed. In base scenario (vaccination coverage: 80%, and vaccine price: 58 dollars per dose), pneumococcal disease incidence reduction would be superior to 60% for invasive infections, and to 30% for non-invasive infections, but th...

Urinary tract infection (UTI) is the most common condition causing individuals to seek medical consultation. [1,2] It is considered as one of the major health problem next to respiratory and gastro intestinal infections in human.
