Chitosan/montmorillonite (CTS-MMT) composite beads were Incline Control used as adsorbents for the removal of silver ion (Ag+) from aqueous solution.Equilibrium adsorption was achieved within 150 min at 3% MMT of chitosan solution.The optimum pH value for Ag+ removal was found to be 6-7.The maximum adsorbent dosage for Ag+ removal was 5 g/L.Under a

In this paper, a class of all-metal cavity-backed slot array employing multiple layers, corporate-feed waveguide network, and coaxial-to-ridged waveguide transition is proposed.The frequency band flexibility of Coffee this class of array with a fixed aperture is demonstrated using the direct metal laser sintering (DMLS) technique.Given a fixed aper

The coexistence of acute ischemic stroke and acute myocardial infarction is rare.The reperfusion therapy used in the therapeutic window is the golden standard in the treatment of both diseases.We present a case of successful aspiration thrombectomy circumflex anterior artery and effective mechanical thrombectomy of the right internal carotid artery

Cambrian Series 2 shelly fossils from thick carbonate successions in East Antarctica have received limited systematic treatment through the 20th century.Described here are the East Antarctic camenellan tommotiids from the Shackleton Limestone in the Central Transantarctic Mountains and Alarm Clock the Schneider Hills limestone in the Argentina Rang
