Attract and kill (AK) technology was evaluated against the Mediterranean fruit fly (Med-fly), Ceratitis capitata W.. Treatment was carried out in two peach orchards of four hectares each; first one located in Borj-Touil and the second in El-Kssibi Mornag, Northern Tunisia during the 2012 field season. AK is a specialized system based on hydrolyzed proteins and alpha-cypermethrin. During this …

An exact solution for the unsteady mixed convective MHD flow of an incompressible viscous electrically-conducting fluid over an infinite vertical isothermal plate impulsively held fixed in a uniform stream is presented here. A uniform magnetic field is assumed to be applied transversely to the direction of the flow, taking into account the induced magnetic field. The governing equations are so…

Rotating disk flows arise in many areas of the electrochemical, biophysics, renewable energy systems and materials processing industries. Motivated by industrial applications, we examine a complex multi-physical coupled nonlinear heat transfer regime in the vicinity of a rotating disk incorporating thermal radiation, magnetohydrodynamics, and wall slip and variable thermophysical properties. A…

Optical sensors have wide range of application such as in medicine, astronomy, industry, and others. Sensitivity of symmetric three layered optical waveguide sensor is investigated. The proposed sensor consists of dielectric slab surrounded by metamaterial (MTM) cladding and MTM substrate. MTMs are new artificial materials which have simultaneously negative permittivity ε and negative pe…

In this paper, a comprehensive numerical study is presented for the fully developed two-dimensional flow of viscous incompressible fluid through a curved duct with square cross section. Numerical calculations are carried out over a wide range of the Dean number 100 Dn 6500 for the curvature 0.5 . A temperature difference is applied across the vertical sidewalls for the Grashof numberGr 100 , w…

The flow of information is an important quality assurance system of the subsystem. The use of information technology enables fast data transfer, product modeling, electronic data transfer for the demands of the customers / users, as well as fast and efficient production.In this paper, the analysis of the Macedonian companies is being given in terms of the extent to which they use relevant infor…

Global Positioning System (GPS) is a satellite based navigation system that can be used to locate positions anywhere on earth and proper timing determination. The Global Positioning System (GPS) uses accurate, stable atomic clocks in satellites and on the ground to provide world-wide position and time determination. As a result of their motion and being in the earth gravitational field, these …
