Miniaturized mobile microrobots have opened new applications from biomedical to environmental fields. Among various types of microrobots, recent progress on highly performing planar type could offer a good compromise between the manufacturability and functionality promising for practical applications. The remaining challenges are guarantee their sustainable operations in unclean wet environment...

using ultrasonic devices in endodontics can enhance the antibacterial and tissue dissolving ability of different root canal irrigants such as sodium hypochlorite (naocl) which is the most common irrigant with excellent antibacterial and tissue dissolving abilities. however, due to its high surface tension, its penetration into the irregularities of the root canal system is a challenge. the purp...

Coral reefs are one of the most diverse habitats in the world, yet our understanding of the processes affecting their biodiversity is limited. At the local scale, cleaner fish are thought to have a disproportionate effect, in relation to their abundance and size, on the activity of many other fish species, but confirmation of this species' effect on local fish diversity has proved elusive. The ...

UNLABELLED Vacuum cleaners with a central exhaust may lead to lower airborne dust and allergen concentrations compared with regular vacuum cleaners. In 12 houses, equipped with a central vacuum cleaning system, a standardized vacuum cleaning protocol was performed comparing airborne dust and allergen concentrations between the central system and a regular cleaner. Airborne dust concentrations d...

There is strong evidence that brain nonapeptides are implicated as modulators of a wide array of social and reproductive behaviors in fishes. However, the question remains, as to whether there is a link between the distribution of active nonapeptides across brain regions and fishes specific behavioral phenotypes. To explore this link we compared the nonapeptides' profile across the brains of fi...

Kinjal Patel, PG student at LDCE, Ahmedabad. Phone:9974407792 E-mail: [email protected] Abstract—The common indicators of economic welfare, such as national product and income have reflected the growth of the industry as a major indicator for the development of the nation. But the other angle of industrialization has been the serious damage to the surrounding environment so there is keen n...

Both the spectrum and correlation characteristics are important in constructing excitation sequences to realize the multichannel ultrasonic sensors working together. For LFM excitation sequence, there should not be too many simultaneously fired ultrasonic sensors, because of the limited available frequency band of the ultrasonic ranging system. The optimized CFM excitation sequences are propose...

In ultrasonic tube hydroforming, the tube is hydro formed while the ultrasonic vibration is applied to the die. Prior studies provide experimental proof that ultrasonic tube hydroforming reduces corner radius, improves lubrication and uniform thickness. Use of ultrasonic vibration can decrease friction at the tube-die interface. Few attempts have been made to analyze the wire drawing while the ...

Sustainable development is a three-pronged attack on the future. It is shorthand for balancing economic progress, social equity and environmental quality to provide fulfilling lifestyles for the planet’s inhabitants, both now and in the future. Sustainable development has been progressively embraced by leading industries, national governments, international organisations and financial instituti...
