Objective(s): Neural stem/progenitor cells (NS/PCs) hold a great potential for delivery of therapeutic agents into the injured regions of the brain. Efficient gene delivery using NS/PCs may correct a genetic defect, produce therapeutic proteins or neurotransmitters, and modulate enzyme activation. Here, we investigated the efficiency of a recombinant lentivirus vector ...

In this paper, we designed and implemented an internal multi-band folded monopole antenna for mobile handset. The proposed antenna covers Global System for Mobile Communications (GSM900: 880~960 MHz), Digital Communications System (DCS: 1710~1880 MHz), USPersonal Communications Service (US-PCS: 1850~1990 MHz), Bluetooth(2400~2484 MHz), WiMAX(3400~3600 MHz), and Wireless Local Area Network (WLAN...

A novel single layer, coaxial probe feed compact triple band slotted microstrip patch antenna with modified ground plane for wireless application has been designed and analyzed. The presented antenna, occupying a compact size of 24 × 22 × 1.6mm3, embodies a rectangular slotted patch and a rectangular ground plane modified with open ended step graded slots. The step graded slots are introduced o...

Periodic composite structures, like acoustic metamaterials (AMMs) and phononic crystals (PCs), are able to prevent the propagation of sound elastic waves for some specific frequency ranges, leading emergence so-called band gaps. So far, optimization metamaterial properties therefore gaps has been typically performed on passive PCs AMMs. Hence, gap cannot be tuned anymore after production proces...

We experimentally and theoretically investigate the band-gap and transmission properties of phononic crystal (PC) beams immersed in water. Spectral element method (SEM) is developed for theoretical analysis in which the hydrodynamic loading is taken into consideration. Influence of the hydrodynamic loading on band-gap and transmission properties of the PC beams are studied. To directly detect t...

The increasing use of wireless communication systems, demands antennas for different systems and standards, with properties like broadband, compact, multiple resonant frequencies. The previous chapter discussed the analysis and fabrication of two single frequency EBG antennas. This chapter deals with the design and fabrication of a dual frequency EBG antenna. The bandwidth improvement of a comp...

In this work, we designed a narrow-band filter based on one-dimensional photonic crystal heterostructure featuring an angle-adjustable single-channel. The design presented here is quarter-wave reflector with mirror defect layer in the middle of structure. By combining two defective crystals (PCs), obtained which sub-PCs had wavelengths their modes, that is, same at one incident angle and differ...

Phononic band-gap materials prevent elastic waves from propagating at certain frequency ranges. These materials are called Phononic Crystals (PCs). PCs have been applied to manufacture frequency filters, vibration protection devices, waveguide and to improve ultrasound imaging transducers. Periodic band-gap materials are designed by choosing the location and the size of the band gaps. Many work...

Two experimental factors (dietary treatment with or without pelleted-concentrate supplement (PCS) and sex) were investigated in crossbreed post-weaning calves to monitor their effects on performance, hematological profile, and plasma mineral concentration. Twenty-four post-weaning calves were classified according to sexually (either male or female) and randomly distributed into two dietary trea...
