Single-shot transverse coherence in seeded and unseeded free-electron lasers: A comparison
The advent of x-ray free-electron lasers (FELs) drastically enhanced the capabilities of several analytical techniques, for which the degree of transverse (spatial) coherence of the source is essential. FELs can be operated in self-amplified spontaneous emission (SASE) or seeded configurations, which rely on a qualitatively different initialization of the amplification process leading to light emission. The degree of transverse coherence of SASE and seeded FELs has been characterized in the past, both experimentally and theoretically. However, a direct experimental comparison between the two regimes in similar operating conditions is missing, as well as an accurate study of the sensitivity of transverse coherence to key working parameters. In this paper, we carry out such a comparison, focusing in particular on the evolution of coherence during the light amplification process
Human amniotic membrane for myocutaneous dehiscence after a radical surgical treatment of vulvar cancer: A case report
Background: The application of the amniotic membrane could have a favourable effect on tissue repair and regeneration. We report the first case of implant of an amniotic membrane in a patient affected by myo-cutaneous dehiscence, after a radical surgical treatment for vulvar cancer. Methods: We describe a case of a 74-years-old patient affected by vulvar cancer. After radiotherapy, the patient underwent to an anterior pelvic exenteration with uretero-ileo-cutaneostomy by Wallace, bilateral pelvic lymphadenectomy, omental biopsies, omental flap, bilateral inguinal lymphadenectomy, resection of ulcerated left inguinal lesion, reconstruction with left gracilis muscle flap and locoregional V-Y advancement flap. The patient developed a myo-cutaneous dehiscence. Two months after the surgery, following an accurate curettage of the wound and negative pressure therapy, a patch of human amniotic membrane was implanted. Results: The surgical procedure was easy, feasible and did not require long operating room times. No intraoperative or postoperative complications occurred. The results obtained were encouraging with a marked improvement in the surgical wound. Conclusion: the use of amniotic membranes was safely and easily performed to promote the healing of complicated surgical wounds
BRS Cometa: cultivar de feijoeiro comum do tipo comercial carioca de porte ereto.
O programa de melhoramento genĂ©tico do feijoeiro comum da Embrapa Arroz e FeijĂŁo estĂĄ focado na busca de cultivares mais produtivas, mais resistentes Ă s doenças e de porte ereto, que possibilitem inclusive a colheita mecanizada, para que os agricultores possam ofertar um produto de melhor qualidade ao consumidor final e auferir melhores rendimentos com a cultura. Ă com esta filosofia que estĂĄ sendo lançada a cultivar de feijĂŁo com tipo de grĂŁo comercial carioca BRS Cometa para Santa Catarina, ParanĂĄ, SĂŁo Paulo, Mato Grosso do Sul, GoiĂĄs/Distrito Federal, Mato Grosso, Tocantins, Bahia, Sergipe e Alagoas, com destaque para seu porte ereto, seu ciclo mais reduzido, alĂ©m da resistĂȘncia a trĂȘs patĂłtipos do fungo causador da antracnose, ao mosaico-comum e a moderada resistĂȘncia Ă ferrugem e Ă mancha-angular.bitstream/CNPAF/25039/1/comt_131.pd

Tunability experiments at the FERMI@Elettra free-electron laser
FERMI@Elettra is a free electron-laser (FEL)-based user facility that, after two years of commissioning, started preliminary users' dedicated runs in 2011. At variance with other FEL user facilities, FERMI@Elettra has been designed to deliver improved spectral stability and longitudinal coherence. The adopted scheme, which uses an external laser to initiate the FEL process, has been demonstrated to be capable of generating FEL pulses close to the Fourier transform limit. We report on the first instance of FEL wavelength tuning, both in a narrow and in a large spectral range (fine- and coarse-tuning). We also report on two different experiments that have been performed exploiting such FEL tuning. We used fine-tuning to scan across the 1sâ4p resonance in He atoms, at â23.74 eV (52.2 nm), detecting both UVâvisible fluorescence (4pâ2s, 400 nm) and EUV fluorescence (4pâ1s, 52.2 nm). We used coarse-tuning to scan the M4,5 absorption edge of Ge (âŒ29.5 eV) in the wavelength region 30â60 nm, measured in transmission geometry with a thermopile positioned on the rear side of a Ge thin foil
