Traditional centralized access control has some shortcomings in robustness, trustworthiness and circulation.Blockchains have the advantages of off white 5000 puffs fault tolerance and trust.Smart contracts have the characteristics of automatic execution and flexible expansion.Tokens can well record credential information and transfer easily.In this
Methane (CH4) and carbon dioxide (CO2) are potent greenhouse gases produced as waste in carbon-based fuel processes.This study investigates the use of natural microbial communities to consume CH4 and CO2 and convert these gases into biomass.Seawater enriched with nutrients was exposed to a gas stream containing CH4 and CO2 under either light or dar
In this paper Split Hopkinson pressure bar (SHPB) was used for dynamic testing of nickel coated polyurethane hybrid junk baller band foams.The foams were manufactured by electrodeposition of a nickel coating on the standard open-cell polyurethane foam.High strength aluminium alloy bars instrumented with foil strain-gauges were used for dynamic load
Galectin-14 is specifically expressed in placental trophoblasts, and its expression is reduced in trophoblasts retrieved from the cervix of women voyage et cie santal candle destined to develop early pregnancy loss.However, the roles of galectin-14 in regulating trophoblasts and in the pathogenesis of pregnancy complication have never been investig
Abstract Hyperlenses for ultrasonic imaging in nondestructive evaluation and non-invasive diagnostics have not been widely discussed, likely due to the lack of understanding on their performance, as well as challenges with reception of the elastic wavefield past fine features.This paper discusses the development junk baller band and application of
