In this study, the impact of some organic matters and a moisture super absorbent were investigated on available water and delay of permanent wilting point in a sample soil of Rasht landscape. In incubation stage, 12 Treatments including control (70% v/v soil with 30% of the composted manure) and various amounts of soil, municipal compost, composted manure, olives and rice wastes along with a su...
Aging in super glassy polymers such as poly(trimethylsilylpropyne) (PTMSP), poly(4-methyl-2-pentyne) (PMP), and polymers with intrinsic microporosity (PIM-1) reduces gas permeabilities and limits their application as gas-separation membranes. While super glassy polymers are initially very porous, and ultra-permeable, they quickly pack into a denser phase becoming less porous and permeable. This...
BACKGROUND Large quantities of water condensation occur in the anaesthesia circuit during low-flow anaesthesia. We hypothesized that cooling of the CO2 absorbent would prevent water condensation. METHODS To cool CO2 absorbent efficiently, we constructed a novel temperature gradient reduction (TGR) canister, which was cooled by a blower. Experiments were divided into three groups: the conventi...
Mn1-xZnxFe2O4 (0 ≤ x 0.65) nanoferrite particles were used as filler in a silicone polymer matrix order to obtain composite material with the purpose of absorbing electromagnetic radiation. The was characterized by X-ray diffraction, transmission electron microscopy and force modulation (FMM) properties means network impedance analyzers. It observed that higher concentrations Znx (x = 0.5 prese...
