Effect of Curvature of Tip and Convexity of Electrode on Localization of Particles
(Scientific Research, 2015-12)We investigate the effect of curvature of the tip and the convexity of an electrode on the localization of suspended particles under the combined effect of dielectrophoresis and AC electroosmosis through simulations using ... -
Experimental and Numerical Investigations on Plate-Type Heat Exchanger Performance
(Scientific Research, 2015-03)Low-grade Thermal Energy Conversion (LTEC) is a potential source of renewable energy. One of its forms is the Ocean Thermal Energy Conversion (OTEC) in which the temperature difference between the warm surface water and ... -
Weis-Fogh Mechanism Mathematic Model of Wave Power Generation Device
(Scientific Research, 2014-12)A Weis-Fogh mechanism wave power generation system is designed, its physical model and mathematical model are discussed, and the component expressions of fluid dynamic expression are derived. Adopting numerical integral ... -
Impact of the Housing on the Air Flow and the Thermal Behavior of an Automotive Clutch System
(Scientific Research, 2015-03)New directives and increasing competition push automakers to get better performances (engine power increase), along with mass and size reduction (consumption). These evolutions lead to an increase of the thermal solicitations ... -
Novel Power Law of Turbulent Spectrum
(Scientific Research, 2014-06)This paper is concerned with novel power law of turbulent energy spectrum and the relevant experiment in tidal current. The power law in the inertial sub-range has been proposed in such a way that the power of the ... -
Simulation of Average Turbulent Pipe Flow: A Three-Equation Model
(Scientific Research, 2014-03)The aim of this study is to evaluate a three-equation turbulence model applied to pipe flow. Uncertainty is approximated by comparing with published direct numerical simulation results for fully-developed average pipe flow. ... -
The Research of Performance Comparison of Displacement and Mixing Ventilation System in Catering Kitchen
(Scientific Research, 2013-07)A commercial kitchen is a complicated environment where multiple components of a ventilation system including hood exhaust, conditioned air supply, and makeup air systems work together but not always in unison. And the ... -
Effect of Hub-Ratio on Performance of Asymmetric Dual-Rotor Small Axial Fan
(Scientific Research, 2013-07)Currently, domestic and abroad scholars put more attention on contra-rotating dual-rotor axial fan. But there is less scholars study on asymmetric dual-rotor small axial fan, which is one of the contra-rotating dual-rotor ... -
Managing leaf-cutting ants: Peculiarities, trends and challenges
(published online, 2014-03)Leaf-cutting ants are generally recognized as important pest species in Neotropical America. They are eusocial insects that exhibit social organization, foraging, fungus-cultivation, hygiene and a complex nest structure, ... -
Integrated pest management tactics and predatory coccinellids: A review
(published online, 2016-02)Integrated pest management, defined as an approach in comprehensive meaning by the selection, integration and implementation of sustainable pest control tools to keep pest status to endurable levels while maintaining a ... -
Insecticidal effect of plant extracts on two termite species
(published online, 2011-06)The insecticidal contact activity of two desert plant extracts, Withania somnifera and Solanum incanum (Tubiflora: Solanaceae) was tested against the workers of the two species, Amitermes messinae and Microtermes najdensis ... -
Indigenous approaches for the management of termite and white grub in upland rice
(2014-01)Termites and white grubs are of regional importance in upland rain fed rice. Major insect pests in upland rice are stem borers, gundhi bug, mealy bug, root aphids, white grubs, and termites (Odontotermes obesus and ... -
Impacts of termites on selected soil physicochemical characteristics in the highlands of Southwest Ethiopia
(published online, 2017-03)Termites are reported to improve soil physicochemical properties thereby enhance soil fertility of their mound and foraging areas. Empirical study pertaining to these effects is missing in Southwest Ethiopia. For this ... -
Hunting strategy of a generalist ant species proposed as a biological control agent against termites
(Kluwer Academic Publishers., 1999-09)We studied the hunting behaviour of Myrmicaria opaciventris (Hymenoptera: Formicidae) in order to evaluate if it can be used as a biological control agent against the termites that damage sugarcane plantations. Hunting ... -
Ecology of termites from the genus Nasutitermes (Termitidae: Nasutitermitinae) and potential for science-based development of sustainable pest management programs
(published online, 2017-02)The genus Nasutitermes is among the most abundant wood-feeding Termitidae and an 48 extremely diverse and heterogeneous group in terms of its biogeography and morphology. 49 Despite the major role of several Nasutitermes ... -
