OBJECTIVES To generate baseline data for indoor airborne fungal spores in noncomplaint residential properties (with no moisture/mold-related problems) and to identify home characteristics indicative of elevated fungal levels. METHODS Air samples were collected onto petroleum jelly-coated slides from living rooms of 100 residential properties in Leicestershire, United Kingdom, using a Burkard ...

Carbon with a metallic reflection was prepared from polyaniline (PANI) vapor deposited on the inner quartz wall of furnace. Electron probe microanalyzer analysis proved that resultant contained carbon, oxygen, nitrogen, and sulfur atoms. A Dysonian line shape paramagnetic properties observed for resulting carbon PANI in electron spin-resonance spectroscopy measurement. The resistance vs. temper...

Reflection high-energy electron diffraction is presented as a contactless, surface-specific method to probe the ion organization and layering at the ionic liquid-solid interfaces. Three regimes can be identified for the structure of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM][Tf2N]) on highly oriented pyrolytic graphite, which is strongly dependent on the distances of ...

The technological process for manufacturing seamless steel tubes in the Sisak Rolling Mill includes the heating of the charge for processing in the hearth-rotating furnace. Description of the furnace and its operation can be found in literature 1 . In the process currently applied for producing the tubes with the outer diameter of 168.3–356.6 mm the temperature is between 1280 and 1300 °C 2 . T...

The present paper reports a statistical analysis of the performance of the blast furnace number X at the Bhilai Steel Plant over a period of sixteen years with the special reference to the quality and consumption of sinter . The variation in basicity and consumption of sinter, for the blast furnace data considered , is wide. The range of data covers high level to almost nil amount of raw limest...

INTRODUCTION This report presents the results of two trials conducted with the Blast Furnace Granular Coal Injection System at Bethlehem Steel Corporation's Bums Harbor Plant. The trials were conducted using granulated and pulverized high volatile coal from Colorado. The first trial was conducted to quantify the effect that a high volatile western coal, Colorado Oxbow, has on the blast furnace ...

The difficulty in measuring load temperatures inside reheating gas furnaces may be circumvented by appropriate use of on-line numerical models. In this article we describe a model of pusher furnaces, used to reheat steel slabs. The model uses thermocouple measurements at fixed positions inside the furnace to calculate the temperature of the combustion products, and takes into account radiative ...
