Signatures of superconducting and pseudogap phases in ultrafast transient reflectivity of Ca(Fe0.927Co0.073)(2)As-2

We present femtosecond time-resolved pump-probe spectroscopic studies of a pseudogap (PG) along with the superconducting (SC) gap in an overdoped iron pnictide Ca(Fe0.927Co0.073)(2)As-2. It is seen that the temperature evolution of the photo-excited quasiparticle (QP) relaxation dynamics, coherently excited A(1g)-symmetric optical phonon and two acoustic phonon dynamics behave anomalously in the vicinity of the superconducting transition temperature T-c. A continuous change in the sign of the experimentally measured transient differential reflectivity Delta R/R signal at the zero time delay between the pump and probe pulses at a temperature of similar to 200K is inferred as an evidence of the emergence of the PG phase around that temperature. This behavior is independent of the pump photon energy and occurs for crystals without the spin density wave phase transition. Copyright (C) EPLA, 2014

Diário da Constituinte [gravação de vídeo] : [programa n. 073]

Na Comissão da Organização Eleitoral, Partidos e Garantias das Instituições da Assembleia Nacional Constituinte (ANC), todos os temas polêmicos serão discutidos duas vezes antes da votação final. São eles: o papel dos militares, criação de uma corte constitucional e a fixação dos tempos dos mandatos. Saulo Queiroz (PFL-MS) acredita que assim a participação será democrática. A Comissão de Sistema Tributário, Orçamento e Finanças quer acabar com a impunidade dos crimes de colarinho branco. O deputado Fernando Gasparian (PMDB-SP), relator da Comissão, propõe a punição rigorosa e o impedimento da União em assumir os prejuízos financeiros causados por eles. A Subcomissão dos Negros, Populações Indígenas, Pessoas Deficientes e Minorias reafirma e amplia o direito das minorias. José Carlos Sabóia (PMDB-MA) relata que caberá a Constituição e ao Tribunal Constitucional impedir qualquer prática de discriminação racial. Populares falam a respeito. Para os deficientes físicos, alguns direitos já estão garantidos no anteprojeto. Nelson Seixas (PDT-SP) afirma que agora as entidades responsáveis pelos interesses dos deficientes viverão um novo momento. Ione Pereira França, presidente da Associação dos Deficientes Físicos de Brasília, acredita que só através da implementação de leis haverá mudanças.

MS 073 Guide to the William C. Moloney MD papers; 1952-1954

William C. Moloney MD kept a personal journal, with photographs, for much of his two years in Japan with the Atomic Bomb Casualty Commission. In January of 1986, Dr.Moloney donated his journal, correspondence and diary pages to the Harris County Medical Archive. He died in 1998 at the age of 91. His first contribution was a set of ten reprints representing his work with the ABCC from 1952 to 1954. Dr.Moloney's journal is a fine document, one which will be of great use to historians. It is an important record of personal impressions, thoughts and details of events. The journal gives new insights into the work of the ABCC and into the people who participated in that work. Dr. Moloney wrote in his journal from April 1952 to February 1954. The Korean War was on and there was a great deal of military activity in southern Japan. The collection is open for research. The collection consists of a handwritten journal, loose calendar or notebook pages and some reprints. The journal is in generally fair condition. The paper is slightly acidic and the binding is loose. There are numerous photos glued onto the pages. The collection encompasses the years 1952-1954 and is 0.25 cubic feet (1 box).
