This study investigated the effect of several substrate types and moisture sources on the developmental and reproductive fitness of the zoophytophagous predator Orius laevigatus (Fieber) (Hemiptera: Anthocoridae) when fed a factitious prey (i.e. unnatural prey) Ephestia kuehniella (Zeller) eggs, or a meridic artificial diet based on hen's egg yolk. O. laevigatus is known to feed on plants as an...

Two cu-galactosidase (a-o-galactoside galactohydrolase, EC 3.2.1.22) isozymes have been highly purified from human placental tissue. Both isozymes appeared to be homogeneous based upon disc gel electrophoresis. Both were bound by concanavalin A-Sepharose and stained positively with the periodic acid-Schiff stain indicating that each contained carbohydrate. The A isozyme had a molecular weight o...

MEMS Inlet Valve for Portable Sensor Systems With funding support from DARPA, RTI developed the electrostatic “artificial eyelid” actuator, which has a diversity of applications including optical shutters, electrical switches, tunable capacitors, and microvalves. The artificial eyelid consists of a flexible curled film fabricated from polymer and metal layers which is anchored to a substrate (e...

OBJECTIVES This study investigates biomechanical implications of walking with indigenous "Kolhapuri" footwear compared to barefoot walking among a population of South Indians. MATERIALS AND METHODS Ten healthy adults from South India walked barefoot and indigenously shod at voluntary speed on an artificial substrate. The experiment was repeated outside, on a natural substrate. Data were colle...

We propose a self-assembling procedure for the fabrication of GaAs islands by Droplet Epitaxy on silicon substrate. Controlling substrate temperature and amount of supplied gallium is possible to tune the base size of the islands from 70 up to 250 nm and the density from 10(7) to 10(9) cm(-2). The islands show a standard deviation of base size distribution below 10% and their shape evolves chan...

Abstract. Artificial substrates associated with renewable offshore energy infrastructure, such as floating wind farms, enable the establishment of benthic communities a taxonomic composition similar to that naturally occurring rocky intertidal habitats. The size biodiversity impact and structural changes in habitats will depend on selected locations. aim study is assess colonisation zonation, q...
