The Unified Power Quality Conditioner (UPQC) is distribution FACTS device which is combination of Shunt compensator (DSTATCOM) and series compensator (DVR) connected back to back by a common DC link capacitor. The DC link capacitor generally as per requirement of shunt compensation which is 1.6 V of line voltage of sy…
Damaged eggshells result in losses of eggs. The genetic mechanism of variable eggshell strength is still unclear. The current study was conducted to verify whether the eggshell calcification related genes, CALB1, SPP1, DMP4, BMP2 and SLIT2, were associated with eggshell mechanical property. For this purpose quantitati…
Curcumin is a natural bioactive compound originated from the rhizomes of turmeric (Curcuma longa L.). This study was performed to investigate formic acid and microwave assisted extraction of curcumin from turmeric (Curcuma longa L.). In order to enhance the curcumin extraction, different parameters such as particle si…
Sorption kinetics and isotherms of phenol by four carbonaceous sorbents (activated carbon (AC), mesoporous carbon (MPC), bamboo biochar (BBC) and oak wood biochar (OBC)) were compared in this study. MPC has the fastest sorption rate and initial sorption potential, which were indicated by sorption rate constants and in…
Hardware corrosion on porcelain and glass insulators has occurred on ±800 kV UHVDC transmission lines in China. Iron cap corroded insulators all located at the negative polarity and pin corroded insulators concentrated in positive polarity. The corrosion mechanism is analyzed from the aspect of electrochemistry and th…
Summary A combined experimental and computational approach is presented in order to study reactor fouling in high pressure LDPE tubular reactors. Indications are found that fouling is a process driven by low polymer diffusion speeds and higher friction in the region close to the reactor wall. These findings can explai…
Proteases active at low temperature or high pH are used in many commercial applications, including the detergent, food and feed industries, and bacteria specifically adapted to these conditions are a potential source of novel proteases. Environments combining these two extremes are very rare, but offer the promise of…
We report the synthesis of noncentrosymmetric BiPd single crystal by the self-flux method. The BiPd single crystal is crystallized in monoclinic structure with the P2(1) space group. Detailed SEM (scanning electron microscopy) results show that the crystals are formed in a slab like morphology with homogeneous distrib…
The electronic structures and optical properties of intrinsic SnO 2 , Zn-doped SnO 2 , SnO 2 with Sn vacancy (V Sn ) and Zn-doped SnO 2 with Sn vacancy are explored by using first-principles calculations. Zn-doped SnO 2 is a p-type semiconductor material, whose Fermi level shifts into the valence band when Zn atoms su…
Abstract Synthesis of Au@Ni bimetallic core shell nanostructures using commercially available soya bean oil as the solvent through a sequential reduction strategy is reported. The energy efficiency and economic viability comes from the much milder temperatures and replacement of expensive and environmentally hazardous…
Particulate composites are widely used in the materials world. An understanding of their damage behaviour under a variety of loading conditions is necessary to inform models of their response to external stimuli. In the present experimental study, fine and coarse grained RDX-HTPB composites have been used to investiga…
The implantation formation of InAs nanoclusters in silicon and silica and their modification via irradiation with Xe ions with an energy of 167 MeV and a fluence of 3 × 10 14 cm –2 are studied. It is found that post-implantation annealing and irradiation with high-energy ions alter the size and shape of nanoclusters a…
In LiNbO3:Zn crystals with near-threshold doping levels ( 4.5–4.7 mol % Zn), high-temperature measurements and high-temperature annealing under short-circuit conditions lead to considerable changes in spontaneous unipolarity. The considerable changes in spontaneous unipolarity are accompanied by well-defined low-frequ…
SiO 2 –TiO 2 binary aerogels have been synthesized for the first time using methyl tert -butyl ether as supercritical fluid. It has been shown that the aerogels prepared in methyl tert -butyl ether and isopropanol contain nanocrystalline anatase and that amorphous SiO 2 –TiO 2 aerogels with a homogeneous distribution…
Controlling the flow of spin and charge currents in topological insulators (TIs) is a crucial requirement for applications in quantum computation and spin electronics. We demonstrate that such control can be established in nanoscopic two-dimensional TIs by breaking their time-reversal symmetry via magnetic defects. Th…
Chicken is one of the most popular domesticated species worldwide, as it can serve an important role in agricultural as well as biomedical research fields. Because it inhabits almost every continent and presents diverse morphology and traits, the need of genetic markers for distinguishing each breed for various purpos…
In this work, we show that aluminium doped with low concentrations of magnetic impurities can be used to fabricate quantum devices with intrinsic cooling capabilities. We fabricate single electron transistors made of aluminium doped with 2% Mn by using a standard multi angle evaporation technique and show that the qua…
An investigation on the mechanism of relaxation of axially confined 400 GeV/c protons to planar channeling in a bent crystal was carried out at the extracted line H8 from CERN Super Proton Synchrotron. The experimental results were critically compared to computer simulations, showing a good agreement. We identified a…
One of the control strategies of DVR (Dynamic Voltage Restorer) is minimum energy control strategy which is explained in this paper. The main duty of power system is to supply their customers a uninterruptable power supply at all the times, but in practice it is not happening. However, the total power system is the la…
Data on clayey swelling soils with gilgai microtopography are systematized. Classifications of gilgai microtopography representing regularly alternating microhighs and microlows are discussed, and its geometric parameters under different landscape conditions are considered. Gilgai microtopography is developed within f…
