This paper aims at reducing greenhouse gas emissions, which contributes to carbon neutrality, and, the same time, preventing mine heat disasters and extracting highly mineralized (HM) water, so as realize synergy between CO2 storage (CS) geothermal extraction utilization (GEU) in a high temperature (HT) goaf. With this purpose, an innovative CS-GEU technology for HT HM water deep is proposed, b...

N AUTOMATIC PIPETING DEVICE for measuring small samples of serum or other biologic fluids has been described (1). This type of pipet can be used to measure 0.1 to 0.2 ml. volumes of different samples accurately. It is self-cleaning and can be used repeatedly from sample to sample. Because of these desirable features it was applied to the manometric Van Slyke apparatus (2) for the measurement of...

The capability of supercritical CO2 to extract edible oil from handmade Argan press cake was investigated. aim is enable Moroccan cooperatives improve their economic situation by valuing the argan cake, which nowadays considered as a waste, applying clean extraction process. Extraction experiments were conducted at 300 and 400 bar, 333 K 0.14 kg/h on dried biomass. fatty acids tocopherols compo...

Two isostructural 1D compounds {[M3(hpdc)2(H2O)6] 2H2O}n (M = Mn, Co; H3hpde = 2-hydroxypyrimidine-4,6-dicarboxylic acid) were synthesized by the in situ hydrothermal reactions of 2-chloropyrimidine-4,6-dicarboxylic acid with MCl2 (M = Mn, Co) and NaOH; the MnII compound shows spin-canted antiferromagnetism, whereas the CoII compound exhibits the coexistence of spin-canting and a two-step field...

Supercritical fluid extraction was used to extract the alkaloid N-[7-(3',4'-methylenedioxyphenyl)-2(Z),4(Z)-heptadienoyl]pyrrolidine from leaves of Piper amalago L. A three-level orthogonal array design matrix, OAD OA9(34), was used for optimization of the parameters of supercritical extraction of the alkaloid, employing supercritical carbon dioxide: extraction time (20, 40, and 60 min), temper...
