in this study, residues of imidacloprid (confidor) were measured in greenhouse cucumbers in mazandaran province, iran. confidor 200 sl was applied at the recommended rate (30.0 g ai ha-1) and its double (60.0 g ai ha-1). samples were collected at 1 h to 21 days after application and analyzed to determine the content and dissipation rate of imidacloprid. . analysis was carried out by the quecher...

In this document an idea is submitted how IP and ARP can be used on inhomogeneous FDDI networks (FDDI networks with single MAC and dual MAC stations) by introducing a new protocol layer in the protocol suite of the dual MAC stations. Thus two dual MAC stations are able to do a load splitting across the two rings and use the double bandwidth of 200 Mbits/s as single MAC stations. The new layer i...

background: conventional tomography used for evaluation of the small areas of the jaws provides acceptable information. it has some advantages of availability, less radiation dose and costin comparison to computed tomography (ct) and cone beam ct. double emulsion film usuallyused for taking tomograms requires less exposure than single emulsion film; on the other hand,the latter provides more sh...

This paper proposes a general design method of modular multiphase permanent-magnet synchronous machine with hybrid single/double layer (HL) fractional-slot concentrated winding (FSCW), which indicates that double-layer (DL) FSCW machines satisfying two preconditions can be transformed into HL machines. different slot and pole number combination are designed to prove the feasibility universality...

Abstract: nanocrystalline nickel samples with the grain size of ~25 nm were prepared via direct current electrodeposition andaluminized for different durations by pack cementation method at 500 means of SEM, EDS and XRD techniques. According to results, short time aluminizing resulted in the formation of asingle aluminide layer whereas at long duration two distinct aluminide layers were formed....

Quantum wells (QWs) constitute one of the most important classes of devices in the study of two-dimensional (2D) systems. In a double-layer QW, the additional "which-layer" degree of freedom gives rise to celebrated phenomena, such as Coulomb drag, Hall drag, and exciton condensation. We demonstrate facile formation of wide QWs in few-layer black phosphorus devices that host double layers of ch...

Ordered Mesoporous Carbon (OMC) represents an interesting material for electric double layer capacitors which has the high surface area, easily accessed ordered pore channels and lower production cost. In this work, CMK-3 as promising OMC has been fabricated using the ordered mesoporous silica SBA-15 as a template. The structure and morphology of CMK-3 are characterized by X-ray diffraction...

Permanent Magnet Machines (PMM) with a phase number (m) higher than three allow redundancy and lower torque ripple compared to their three phase counterparts. In this paper, a six phase permanent magnet machine with surface rotor magnets, designed with fractional slot tooth winding is proposed. A stator design with fractional slot tooth winding allows the design of a compact machine through sho...
