Chemicals and Materials All chemicals used in the experiments (KBr, Fe2(SO4)3, H2SO4, ethanol, Rhodamine B) are analytical grade or better provided by Sinopharm Co., China. All aqueous solutions are prepared with deionized water (18.2 MΩ, Milli-Q, Millipore Corp., France). ITO glass slides were washed in an ultrasonic cleaner by isopropanol and deionized water for several times and dried by blo...

In this in vitro study, we investigated the efficacy of sodium hypochlorite (NaOCl) and calcium hydroxide (Ca(OH)2) in dissolving necrotic tissue and cleaning root canals. In the first part of the study, 0.5% NaOCl solution and Ca(OH)2 paste and solution were tested with samples of necrotic bovine muscle in different treatment modes and for different periods. The necrotic tissue was weighed bef...

The new copper processing plant of the Sarcheshmeh copper complex consists of two parallel circuits. After a primary crushing, the ore is sent to a SAG mill, and the product is further ground in a ball mill. The overflow of the hydrocyclones is fed to a flotation circuit that contains 8 rougher tank cells (RCS130), 3 cleaner cells (RCS50), 5 scavenger cells (RCS50), and a flotation column (as r...

this paper shows how game theory can be applied to modeling the interaction between government and manufacturer in implementation of cleaner production. a generic game model based upon ‘two-person non-cooperative’ static game is created to allow various strategic actions being tested by stages, and aid decision making by selecting optimal strategy for both manufacturer and policy maker to reduc...

PURPOSE The effects of air cleaners on the removal of airborne indoor allergens, especially house dust mites (HDM), are still controversial. The objective of this study is to evaluate the effect of an air cleaner with an electrostatic filter on the removal of airborne mite allergens. MATERIALS AND METHODS A dried HDM culture medium that contained mite body particles and excretions was dispers...

Interactions between the bluestreak cleaner wrasse Labroides dimidiatus and its client reef fish are a textbook example of interspecific mutualism. The fact that clients actively visit cleaners and invite inspection, together with evidence that cleaners eat many client ectoparasites per day, indeed strongly suggests a mutualistic relationship. What remains unknown is how parasite removal affect...

This article considers the suitability of current robots designed to assist humans in accomplishing their daily domestic tasks. With several million units sold worldwide, robotic vacuum cleaners are currently the figurehead in this field. As such, we will use them to investigate the following key question: Could a robot possibly replace the hand-operated vacuum cleaner? One must consider not ju...

The movement of robots from the production line to the service sector provides a potentially radical solution to innovate and transform public service delivery. Although robots are increasingly being adopted in service delivery (e.g., healthand eldercare) to enhance and in some cases substitute labour-intensive services, the public administration research community is short on knowledge of the ...

The effects of seven commercially available alkaline cleaners used in the food processing industry, 0.025 M NaOH, and 0.025 M KOH on viability of wild-type (EDL 933) and rpoS-deficient (FRIK 816-3) strains of Escherichia coli O157:H7 in logarithmic and stationary phases of growth were determined. Cells were treated at 4 or 23 degrees C for 2, 10, or 30 min. Cleaners 2, 4, 6, and 7, which contai...
