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...

Arguments are presented favouring the step-wise introduction of mechanisation into cane harvesting. The multi-pass "McConnel" system of whole stick harvesting offers such a phased introduction. Three machines are introduced in the following order as labour becomes scarcer a versatile loader, a reaping aid which leaves the cane in orderly swaths "inline", and a pickup cleaner-bundler which takes...

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...

Manual work is taken over the robot technology and many of the related robot appliances are being used extensively also. Here represents the technology that proposed the working of robot for Floor cleaning. This floor cleaner robot can work in any of two modes i. e. "Automatic and Manual". All hardware and software operations are controlled by AT89S52 microcontroller. This robot can p...

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 growing concerns regarding sustainability and a firm's effects on the environment explain important role that environmental management may play in corporate reputation. Following premises of stakeholder approach dynamic capability theory, we explore how comprehensive (environmental innovation [EI] cleaner production [CP]) impacts By analyzing panel data European manufacturing firms, show EI...

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...

Cleaner shrimps are ecologically important members of coral reef communities, but for many species, cleaner status (i.e. dedicated, facultative and mimic), clientele and ecological role remain unverified or described. On Caribbean coral reefs, the spotted 'cleaner' shrimp Periclimenes yucatanicus forms symbioses with sea anemones that may serve as cleaning stations for reef fishes. The status o...
