When the closure member is placed on the purge system, weight of that package surpasses a spring force, opens the valve and admits the replacing gas to flow. When an empty isolation enclosure is placed on the system, the weight is not sufficient to open the valve, so that only enclosures...
The fine structure of the parabronchi and the gas exchange area of the Adelie penguin lung 来自 Semantic Scholar 喜欢 0 阅读量: 81 作者:HE Drescher,U Welsch 摘要: The parabronchi of the Adelie penguin are endowed with wide atria forming pockets between a loose meshwork of bundles of smooth...
The past few years have witnessed a veritable explosion in the development of new methods for the isolation and structure determination of natural products. This is true in particular for the applications of novel separation technologies and modern spect
This paper considers when and how oceanic mixing processes affect gas exchange. The two processes considered are wave breaking and Langmuir circulations. The approach taken is to predict the strength of the Langmuir cell overturning as a function of surface forcing. It is demonstrated that although ...
The microbiome is intricately linked with soil structure, such as aggregation and pore connectivity, because this structure regulates the flow of water, oxygen and nutrients through the system. In this Review, we summarize the key functions of soil microbiomes in agroecosystems, highlight the ...
Numerical Study of Latent Heat Discharge of a Phase Change Material Shell-and-Tube Thermal Energy Storage System The solar heat exchanger, a phase-change heat storage system, is designed in this work. A numerical analysis was carried out to examine the impact of ... Oudaoui, K.,Faraji, M...
1). According to reported works, prolonged higher temperature pyrolysis can result in the vanish of Zn22. Fig. 1 Schematic illustration of active site structures in transition metal–nitrogen–carbon system. Light yellow, blue and pink ivory balls represent carbon, nitrogen and transition metal ...

Then, the air of the aerosol was exchanged with Ar (purity: 99.99%) through a gas exchange device. The aerosol particles in the Ar flow were then analyzed using HR-ToF-AMS. The HR-AMS spectra acquired in the highly sensitive V mode were used to quantify the atmospheric concentrations of ...
