Assessment of Risk for Asthma Initiation and Cancer and Heart Disease Deaths among Patrons and Servers due to Secondhand Smoke Exposure in Restaurants and Bars

Lifetime excess risk of cancer death, ischaemic heart disease death, and asthma initiation among non-smoking restaurant and bar servers and patrons in Minnesota and the US were estimated using weighted field measurements of SHS constituents in Minnesota, existing data on tobacco use, and multiple dose-response models.

Tankless Water Heaters: Do They Really Save Energy?

The in situ efficiency of the storage water heaters was nearly 20% lower than rated, while that of the tankless water heaters was only 10% lower. This paper will discuss the causes, consequences, and possible ramifications of this reduced efficiency.

Application of a Linear Input/Output Model to Tankless Water Heaters

This study evaluates the applicability of a linear input/output model to gas-fired, tankless water heaters. The model can be used to reproduce performance metrics, such as the energy factor, and can be used to evaluate the impacts of alternative draw patterns and conditions.
