Parents often express concerns about that technology, particularly video has on their children. Indeed, have been associated with problems social isolation and a drop-off in academic achievement, and games containing violence shown to increase aggressive thoughts and. Frequent interaction with video games been associated with subsequent problems functions such as attention and impulse-control H...
We propose a strategy to identify the complementarity or substitutability among technology bundles. Differences between the observed distribution of technology choices can be subjected to statistical tests. Combinations of technologies that occur with greater frequency than would occur under independence are complementary technologies. Combinations that occur with less frequency are substitute ...
There are some reports on the lignan constituents of Linum spp. In this study, we investigated the cyototoxicity of Linum spp. in vitro cultures for the first time. If they show significant cytotoxic activity, they will be valuable candidates for isolation of cytotoxic compounds in large scale from them by tissue culture technology. In our study, we chose normal root, hairy root and calli cultu...

the purpose of this study was to investigate the impact of blended learning and multimedia softwares on iranian efl students vocabulary learning. in addition, the present study tried to examine the extent to which multimedia softwares can be applied into efl classes in iran. it also attempted to find out students attitudes toward using these softwares. to this end, 87 iranian efl learners at el...
We present the concept of a virtual node as means to achieve predictable integration of software components with real-time requirements. The virtual node is based on the technology using the hierarchical scheduling framework to achieve temporal isolation between components (or sets of components). The temporal isolation means that all components deployed to a virtual node will retain their temp...
In this paper, a matching circuit for RF diplexer for mobile communication is proposed. Most wanted bands in wireless technologies like GSM and DCS is used. Both bands are designed by using stepped impedance resonators with single order and matching between this two are implemented by Yjunction method. Cutoff frequency for GSM and DCS band are 925 MHz and 1795 MHz. Microstrip Technology is prop...
DSRC provides high speed radio link between Road Side Equipment and On-Board Equipment within the narrow communication area. In this paper, a 5.8 GHz down-conversion mixer for DSRC communication system is designed and fabricated using 0.8 m SiGe HBT process technology and RF/LO matching circuits, RF/LO input balun circuits and IF output balun circuit are all integrated on chip. The measured per...
In this paper, we introduce a new compact dual-polarized conformal slot antenna fed by two orthogonal Coplanar Waveguide (CPW) semi-discs. To achieve a high isolation between the two ports, a strip is inserted diagonally in the ground plane. The simulations are done using the Computer Simulation Technology (CST) Microwave Studio software. The simulated results show that the proposed antenna pro...
A wavelength interleaver having almost rectangular wavelength response, with 50 GHz free spectral range has been demonstrated using SiON waveguide technology. The device consists of an asymmetric Mach-Zehnder Interferometer (MZI), with a ring resonator coupled to one of its branches. A passband flattened and stopband broadened transfer function with 15 dB isolation for TM polarized light (12 dB...
The TPS2000B Series offers a distinctive range of capabilities in an oscilloscope with controls and menus you will find familiar and easy to use. Available in 2or 4-channel versions, the TPS2000B Series with IsolatedChannelTM technology provides isolation from ground and isolation between channels allowing you to take measurements with less worry about damaging circuitry. Battery power comes st...
