Quang phổ cận hồng ngoại (Near Infra Red Spectroscopy NIRS): là kỹ thuật không xâm lấn có thể được sử dụng để theo dõi ô xy mô não trên nhiều khu vực của bề mặt não. Những kĩ ban đầu chỉ cho phép xu hướng thay đổi nồng độ mô, sau đó những tiến bộ trong quang gian đã đo bão hòa tuyệt đối (Saturation cerebral oxygenation – ScO2). Giá trị bình thường ScO2 từ 58 - 82% và giá lên tới 10% ngưỡng thiế...

Abstract This paper presents experimental data on a centrifugal compressor operated with CO2. Temperature and pressure at the inlet of are varied to cover supercritical region from liquid-like gas-like region. In addition, conditions in two-phase also included. Thus, test campaign considers thermodynamic relevant for future energy conversion sCO2-Joule cycles. Experimental results presented as ...

Real gas thermodynamic cycles employ state-of-the-art property routines to compute the state properties as ideal relations are inaccurate. Multiparameter equation of (EOS), though accurate, is computationally time consuming due iterative solutions needed for complex cycles. Alternatively, look-up tables alleviate computational but compromise accuracy interpolation and extrapolation schemes. Thi...

Simulation of both the climate of the twentieth century and a future climate change requires taking into account numerous forcings, while climate sensitivities of general circulation models are defined as the equilibrium surface warming due to a doubling of atmospheric CO2 concentration. A number of simulations with the Massachusetts Institute of Technology (MIT) climate model of intermediate c...

The soluble domain of cytochrome c oxidase subunit II (COX2), located in the outer side of the inner mitochondrial membrane, contains a binuclear copper site (CuA) through which electrons flow from cytochrome c to the core of the oxidase where oxygen reduction takes place. Being COX2 encoded in the mitochondrial genome, newly synthesized protein undergoes maturation steps in which it is translo...

This paper focuses on the use of CO2 + SO2 binary mixture as innovative working fluid for closed transcritical power cycles with a minimum temperature above 50 °C. Starting from literature review available experimental data mixture, PC-SAFT EoS is identified suitable model to characterize behavior. Once proper thermodynamic selected this comparison between cycle and sCO2 proposed various plant ...
