Abstract Proton exchange membrane fuel cells are widely utilized in transportation and stationary power generation applications due to their high energy conversion efficiency, substantial density, zero emissions. To address the requirements for internal status monitoring hydrogen purge management supply subsystem of automotive cell systems, this paper proposes an innovative online scheme real-time measurement anode exhaust mixture concentration from stack, utilizing ultrasonic flowmeter....
Glucose can serve as both the source of energy and regulatory signaling molecule in plant. Due to environmental metabolic change, sugar levels could affect various developmental processes. High glucose environment is hardly conductive plant growth but cause development arrest. Increasing evidence indicate that alternative splicing (AS) plays a pivotal role signaling. However, mechanism upon stress remains unclear. The full-length transcriptomes were obtained from samples Arabidopsis...
By studying the evaluation principles of mechanical parts’ form and position errors many kinds error algorithms, presented in recent patents scientific articles, a project was proposed by using modified particle swarm optimization (PSO) with linearly decreasing inertia weights to evaluate errors. With its important parameters being analyzed based on features errors’ evaluation, PSO proved be high accuracy good robustness. The experiments were carried out for evaluating group straight lines...
Nano-TiO2 photocatalysis technology has attracted wide attention because of its safety, nontoxicity and long-lasting performance. However, traditional nano-TiO2 been greatly limited in application band gap can only be activated by ultraviolet light (λ < 387 nm). In this paper, was prepared self-doping method. The synthesized a single anatase crystal type with particle size 10 nm uniform size. addition, high stability good dispersion. More importantly, exhibits excellent visible (400–780 nm)...
Abstract Huge oil reserves are located in ultra-low permeability reservoirs the Ordos basin China. There three key characteristics associated with these reservoirs: low reservoir quality (10 to 13% porosity), (0.3 2.0 mD), and pressures (pressure gradients of 0.0075 0.009 MPa/m). The Chang 6 formation Huaqing field is classified as reservoirs. Water injection maintain pressure important develop horizontal wells. Fracturing design optimization improving well production development...
Abstract The protection of negative pressures generated by the hydraulic transient process in water supply system is crucial to safe and stable operation. In this study, a mathematical model pipeline with multi-undulating terrain was established based on method characteristics (MOC). generation development hammer were analyzed, double one-way surge tank schemes proposed. It proved that first should be located at initial pressure point, second second-highest point rather than highest point....
Two sets of super-synchronization speed control assemblies for two 80 MVA motor-generator units have been developed successfully in order to satisfy the demand toroidal field system HL-2A tokamak. Based on three-phase logical no-circumfluence a.c./a.c. cycloconverter, speeds 2500 kW double fed drive motors regulated by means vector technology. The maximum operating each motor- generator unit has raised from 1488 rpm (revolutions per minute) 1650 and released energy during a pulsed discharge...
This paper discussed a method of PLC controlling motor.Including the start and stop, forward inversion motor, Positive &negative switching in process Running.And realizing low speed, high medium speed switch operation, accurate control step motor number.it was elaborated programming block diagram ladder implementation status detail.
High background signal is a common problem experienced when detecting proteins isolated through immunoprecipitation (IP) by Western blotting (WB). The most frequent cause of high interference from the heavy and light chain fragments denatured immunoprecipitating (or capture) antibody ' by-products IP labeled species-specific secondary antibodies at WB stage. Here we comment on alternative methods for detection immunoprecipitated that avoid labeling to varying extents. Certain have been...
Factor V defi ciency is a rare bleeding disorder, which includes congenital and acquired factor deficiencies.Congenital (CFVD) an autosomal recessive disorder with estimated prevalence of 1:1,000,000. [1]However, deficiency (AFVD) even rarer, as only approximately 200 case reports or series describing this have been reported in the literature.We herein report very unusual patient AFVD.In case, not were prothrombin time (PT) activated partial thromboplastin (APTT) corrected following mixing...
Abstract As one of the important ways to utilize hydrogen energy, fuel cells are receiving more and attention research from countries institutions. To meet practical needs testing performance high-power fuel-cell systems simulate actual application environment as much possible, a system test bench is usually used performance, in which cooling-temperature control has great impact on results system. This paper studies strategy 150-kW-class engine platform, proposes new test-bench...
