The isolated dual active bridge (DAB)-based two-stage AC-DC-DC converters have been widely applied in grid-connected power electronics systems. However, the impedance interactions between DAB converter and AC-DC rectifier can cause instability problems to accurate terminal characteristics of are still not clear due high frequency ac conversion stage. This makes it difficult assess impacts circu...

In our previous study, we compared the two α-amylase enzymes from Bacillus sp.KR8104, BKA∆(N44) and BKA∆(N44C193) which is the secreted form of it. The results indicated that the presence of 193 amino acids propeptide in the C-terminal of BKA∆(N44) changed its enzymatic parameters like an uncompetitive inhibitor in comparison to BKA∆(N44C193). In the present study, we cloned the DNA sequence of...

The investigation of the terminal falling velocity of non-spherical particles is currently one of the most promising topics in sedimentation technology due to its great signifcance in many separation processes. In this study, the potential of Artifcial Neural Networks (ANNs) for the prediction of nonspherical particles terminal falling velocity through Newtonian and nonNewtonian (power law) liq...

The present work comprises the synthesis of one series of diarylmethane dyes containing one or more terminal methoxy substituents together with a variable tertiary amino group. The electronic absorption spectra of the dyes have been determined. As the conjugation of the terminal nitrogen atom improves in the sequence NMez > Kairoline > Julolidine, a progressive hypsochromic shift is observed

We consider the problem of loading vehicles onto a ferry. The order in which arrive at terminal can have significant impact on efficiency packing ferry as it may not be possible to place vehicle an optimal location if is front one dockside queues right point process. As arrival stochastic, we model process two-stage stochastic optimization where objective reduce penalties incurred by failing pa...

Global interest in LNG products and supply chains is growing, demand continues to rise. As a clean energy source, can nevertheless emit air pollutants, albeit at lower level than transitional sources. An plant capable of producing up 126 MMTA was successfully developed simulated this study. A hybrid life cycle assessment model examine the social human health impacts chain’s environmental emissi...

The functionalization of a Csp2-H bond an heteroarene with alkyne represent one the most attractive procedure for late-stage aromatic core, due to structural characteristics and synthetic versatility given by triple carbon-carbon bond. aim this review is cover significant results reported in literature regarding synthesis alkynyl-substituted five-membered heteroarenes selective direct alkynylat...

background: anaphylactic reactions, such as urticaria, edema, respiratory symptoms, and anaphylactic shock often complicate the course of cystic echinococcosis (ce). methods: to investigate the role of the ige immunoreactive antigen 5 (ag 5) in the sero-positive patients with ce, we determined n-terminal of 57 kda subunit of ag5 responsible for ige and c-terminal of this active antigen related ...
