Amid growing academic and policy interest in the influence of think tanks in public policy processes, this article demonstrates the extent of tobacco industry partnerships with think tanks in the USA, and analyzes how collaborating with a network of think tanks facilitated tobacco industry influence in public health policy. Through analysis of documents from tobacco companies and think tanks, w...

We characterized the physical/chemical conditions and the algal and bacterial assemblages in ballast water from 62 ballast tanks aboard 28 ships operated by the U.S. Military Sealift Command and the Maritime Administration, sampled at 9 ports on the U.S. West Coast and 4 ports on the U.S. East Coast. The ballast tank waters had been held for 2–176 days, and 90% of the tanks had undergone ballas...

Mosquito breeding occurred in. both types of septic tanks, wz'th Type A septic tanks shounng heatner breeding, Seventy-two (55.4 percent) of the 130 Type A septic tanks inspected had Aedes albopictus breeding. Besides being a nuisance, mosquito breeding is a potential threat to public health, as Ae. albopictus is a vector of dengue fever. Prolific breeding by Ae. albopictus was encountered in. ...

This study aims to present a philosophical and quantitative perspective of propulsion system for large-scale hydrogen-fuelled liquid-hydrogen (LH2) tanker ship. Established methods are used evaluate the design performance an LH2-carrier JAMILA, ship designed with four cylindrical LH2 tanks bearing total capacity ∼280,000 m3 along cargo using boil-off as power fuel. Additionally, is evaluated ba...

Domestic rainwater tanks have become commonplace in Australia's urban landscape, and have become the physical embodiment of the changing relations between householders, water, and water authorities. The aim of our research was to understand these changing relations by examining how domestic rainwater tanks are inscribed with meanings and assumptions and thus mediate a relationship between house...

Up to now solar heat has been stored mostly in well insulated water tanks. The volume of these tanks is as large as 3 m3 for relatively high solar fractions and up to 70 m3 for full solar coverage for a single-family house. Storage tanks of this size are expensive and space consuming. In new buildings, provisions can be made to accommodate large storage volumes but this type of system is not li...
