The presence of the space station in low-Earth orbit provides a unique vantage point for collecting Earth and space science data.

Sep 23, 2016· The history of atmospheric O2 partial pressures ( P o2) is inextricably linked to the coevolution of life and Earth’s biogeochemical cycles. Reconstructions of past P o2 rely on models and proxies but often markedly disagree. We present a record of P o2 reconstructed using O2/N2 ratios from ancient air trapped in ice. This record indicates that P o2 declined by 7 per mil (0.7%) over the past ...

Gravity separation is achieved based on the difference in specific gravity (SG), shape and particle size of the valuable minerals or metals, as compared with the gangue or host rock and the carrying medium.

The DM cyclone operation is very sensitive to variations of process and design variables. There are optimum ratios of inlet opening: inlet head diameter, vortex finder diameter and spigot diameter. Most cyclone manufacturers still adhere to the DSM recommendations (de Korte and Engelbrecht, 2007). These cyclones are generally mounted at an ...

The degree of deacetylation (DD) of DE-chitin was 27.3%, as determined by conductivity titration . Before mechanical nanofibrillation, DE-chitin was redispersed in MQ water at a concentration of 0.2 wt %, followed by pH adjustment (3.0) with acetic acid under vigorous stirring, to …

Changes in the concentration of atmospheric CO2 and surface air temperature are closely related. However, temperature can influence atmospheric CO2 as well as be influenced by it. Studies of polar ice cores have concluded that temperature increases during periods of rapid warming have preceded increases in CO2 by hundreds of years. Parrenin et al. (p.

Stratospheric air samples have been collected once per year since 1985 over Japan using a balloon‐borne cryogenic sampler and then analyzed for their CO 2 concentrations. The measurements showed high values of CO 2 in the lowest part of the stratosphere, then a decrease with height to 20.0–25.0 km, and almost constant values above this level. From the comparison with the results of …

Sep 25, 2018· To examine gravitational separation of the stratospheric air over Antarctica in austral summer, we collected air samples from altitudes of 10 to 30 km over Syowa Station (69.0°S, 39.6°E) using balloon‐borne cryogenic samplers for the period 1998–2013, and then analyzed them for δ 15 N of N 2, δ 18 O of O 2, δ(Ar/N 2) and δ 40 Ar. The normalized mass ratio “δ,” calculated using ...

One of the simplest and the oldest gas de-dusting methods is gravitational separation of dusts from a gas stream.Devices using simple physical rules (rapid change of flow direction, centrifugal power, spiral traffic etc.) in the gas de-dusting process are called mechanical units.

Nostoc flagelliforme is an edible cyanobacterium with excellent food and herbal values. It has been used as food in China for more than 2000 years. Many studies have been focused on improving the yield and bioactivity of Nostoc flagelliforme polysaccharides although these have ignored the functional properties. In this study, we extracted and purified three polysaccharides (WL-CPS, NaCl-CPS ...
