This study addresses the problem of "faking bad" (malingering) of abnormal types (non paranoid schizophrenia, paranoid schizophrenia, and psychopathy) when answering the EPQ-R-S personality questionnaire and clinical scales. We tested 180 students under two conditions: “fake bad” and “sincerity”. We demonstrated that although answers to EPQ-R-S may be deliberately and specifically modified, thi...

The study concerning the relevance of lung ultrasound in the diagnosis of acute respiratory failure by Lichtenstein and Mezière in CHEST (July 2008) 1 raises a few basic questions. First of all, there is a technical problem: modern ultrasound systems work on the basis of noise reduction. As a result, one sees fewer artifacts. Artifacts are a fundamental component of ultrasound imaging, for inst...

It was proposed that perfect invisibility cloaks can be constructed for hiding objects from electromagnetic illumination [J. B. Pendry, D. Schurig, and D. R. Smith, Science 312, 1780 (2006)10.1126/science.1125907]. The cylindrical cloaks experimentally demonstrated [D. Schurig, Science 314, 977 (2006)10.1126/science.1133628] and theoretically proposed [W. Cai, Nat. Photon. 1, 224 (2007)10.1038/...

in the present work, the znfe2o4 nanoparticle has been successfully synthesized. the obtained sample was characterized by x-ray diffraction (xrd), emission scanning electron microscopy (fe-sem) and its optical property was examined by uv-vis spectrophotometer. fe-sem revealed that the particle size of the znfe2o4 of about 47 nm was synthesized. the photocatalytic performance under uv-vis and vi...
