This work analysed the effects of Biochar (BC) addition to Anaerobic digestion (AD) wastewater Mixed sludge (MS) in semi-continuous mode. A 3 L digester was operated at 37 °C for 100 days, feeding MS collected every three weeks same treatment plant, and 10 g L−1 BC. The average performance (biogas 188 NmL d−1, 68% methane) improved presence BC 244 69% methane). According results multiple linear...

cognitive deficits such as impairments in attention, memory, information processing and executive functioning can be found in some parkinson's disease (pd) patients. recent studies suggested that pd drivers generally performed poorer than their healthy age-matched controls with regards to their cognitive and motor abilities during the psychometric testing. according to michon’s model of ca...

Height of the dielectric substrate material for a microstrip patch antenna is utterly important in terms of controlling bandwidth as well as surface wave. In this paper we have presented a comparative study of effect of height in the performance parameters of Rectangular Shaped Microstrip Patch antenna. The antennas were simulated for purpose of the application of wireless LAN for resonance fre...

This paper summarizes our recent advances in antenna designs for ultra wideband (UWB) applications. Two types of monopoles are studied and developed in our research group. The first type belongs to the electric monopole with a circular disc fed by three different feeding structures. The second type is the magnetic monopole with an elliptical slot. The performances of these two types of antennas...

To establish the sublethal concentrations domain, acute and chronic oral tests were conducted on caged honeybee workers (Apis mellifera L) using imidacloprid and a metabolite, 5-OH-imidacloprid, under laboratory conditions. The latter showed a 48-h oral LD50 value (153 ng per bee) five times higher than that of imidacloprid (30 ng per bee). Chronic feeding tests indicated that the lowest observ...

Circularly polarized millimeter-wave travelling-wave antennas, using substrate integrated circuits (SICs) technology, are designed, fabricated and tested. By using the SICs technology, compact antennas with low losses in the feeding structure and with good design accuracy are obtained. The elementary antenna which is composed of two inclined slots is characterized by full-wave simulations. This...

As the application of sampling system has stretched into image/video compression and video scalable coding areas, many researches have been carried out on how to improve the sampling system’s performance. So far, a lot of approaches have been proposed, such as directional sampling method, and adaptive sampling filter scheme. Every design has its own trade-off between image/video quality and com...

A 12-week feeding trial was conducted with 87 g rainbow trout to evaluate the effects on growth performances, feed efficiency and nutrient digestibility of adding β-mannanase and α-galactosidase enzymes, solely or in combination. Seven diets were prepared by adding β-mannanase, α-galactosidase and mixed enzyme at two different levels (1 g/kg and 2 g/kg) to control diet (without enzyme) includin...

Received Jan 16, 2017 Revised Mar 18, 2017 Accepted Mar 30, 2017 5G technology is using millimeter-wave band to improve the wireless communication system. However, narrow transmitter and receiver beams have caused the beam coverage area to be limited. Due to propagation limitations of mm wave band, beam forming technology with multi-beam based communication system, has been focused to overcome ...

The study evaluated two levels of distillers dried grain derivative (DDGD) (2 and 4% of the total diet) compared with a control diet (0%) on pig growth performances. Thirty-two nursery pigs (22 days of age) were individually housed in stainless steel pens. The pens were located in a clean, environmentally controlled room. The pigs were allowed to consume one of the three diets ad libitum during...
