Four calcium phosphate cement formulations were implanted in the rabbit distal femoral metaphysis and middiaphysis. Chemical, crystallographic, histological analyses made at 2, 4, 8 weeks after implantation. When into metaphysis, part of brushite was converted carbonated apatite by 2 weeks. Some removed mononuclear macrophages prior to its conversion apatite. Osteoclastlike cell mediated remodeling predominant had The same results seen for plus calcite aggregate cement, except with...
The NEMO 3 detector, which has been operating in the Fréjus underground laboratory since February 2003, is devoted to search for neutrinoless double-beta decay (beta beta 0v). half-lives of two neutrino 2v) have measured 100Mo and 82Se. After 389 effective days data collection from 2003 until September 2004 (phase I), no evidence was found approximately 7 kg 1 corresponding limits are T1/2(beta beta0v) > 4.6 x 10(23) yr 0v) 1.0 82Se (90% C.L.). Depending on nuclear matrix element...
The possibility to probe new physics scenarios of light Majorana neutrino exchange and right-handed currents at the planned next generation neutrinoless double beta decay experiment SuperNEMO is discussed. Its ability study different isotopes track outgoing electrons provides means discriminate underlying mechanisms for by measuring half-life electron angular energy distributions.
Observing double beta decay with no neutrinos in the final state, would signal existence of lepton number violating processes and hint at neutrino being a Majorana particle. The impressive effort represented by NEMO-3 experiment sets important constraints on mass lepton-number processes.
Abstract A synergistic extraction solvent for the simultaneous removal of cesium and strontium from acidic solutions has been investigated. The consists of, 4,4′,(5′)‐di‐(t‐butyldicyclo‐hexano)‐18‐crown‐6 (DtBuCH18C6), calix[4]arene‐bis‐(tert‐octylbenzo‐crown‐6) (BOBCalixC6), 1‐(2,2,3,3‐tetrafluoropropoxy)‐3‐(4‐sec‐butylphenoxy)‐2‐propanol (Cs‐7SB modifier) in a branched aliphatic kerosene (Isopar® L). Extraction synergy was observed when DtBuCH18C6 combined with BOBCalixC6 extractant Cs‐7SB...
