Correspondence To the Editor: We reported a rare complication after thoracic endovascular aortic repair (TEVAR) with a chimney stent. A 68‑year‑old patient with no history of chest or back pain history presented to our hospital for evaluation of the endograft for TEVAR of a thoracic aneurysm approximately 4 years previously. Computed tomography angiography showed significant type Ia endoleak an...

The incidence of cancer was investigated among 5266 Swedish chimney sweeps employed for any period between 1918 and 1980. An analysis of the mortality has been reported earlier and showed an increased number of deaths from coronary heart disease, respiratory diseases, and lung, oesophageal, and liver cancer. Excess risks for cancer of the lung and oesophagus were confirmed in this analysis. Amo...

We have designed an anti-evaporative cover for use with the sample and reagent cups and other liquid containers that are required in automated analytical systems. This cover, which is simple in design, consists of a baseplate and a cylindrical chimney. By increasing the height and decreasing the inner diameter of the chimney, evaporative losses can be reduced to less than 0.1%/h; thus, aliquots...

This paper describes an analysis of mortality among census areas in the city of Christchurch, New Zealand. The number of deaths following days with high particulate air pollution were compared with deaths on matched unpolluted days. The possible role of population age structure, relative deprivation (estimated using the NZDep96 index) and local exposure to outdoor air pollution from household f...

Numerous environmental pressures have precipitated long-term population reductions of many insect species. Population declines in aerially foraging insectivorous birds have also been detected, but the cause remains unknown partly because of a dearth of long-term monitoring data on avian diets. Chimney swifts (Chaetura pelagica) are a model aerial insectivore to fill such information gaps becaus...

A three-dimensional numerical model of thermoelectric generator (TEG) modules attached to a large chimney plate is proposed and solved numerically using a control volume based finite difference formulation. The TEG module consists of a thermoelectric generator, an elliptical pin-fin heat sink, and a cold plate for water cooling. In the chimney, the temperature of flue gases is 450-650K. Althoug...

To what extent is the development of a fluid-transport system related to flow within the system? Colonies of the bryozoan Membranipora membranacea have a simple external fluid-transport system with three components: the canopy of lophophores (crowns of ciliated tentacles), the edge of the canopy, and chimneys (raised openings in the canopy). The lophophores pump seawater into the colony and cap...

In this letter we present the first images of the emission of SiO and H 13 CO + in the nucleus of the starburst galaxy M 82. Contrary to other molecular species, which mainly trace the distribution of the star forming molecular gas within the disk, the SiO emission extends noticeably out of the galaxy plane. The bulk of the SiO emission is restricted to two major features. The first feature, re...
