Dilute amorphous (Niioo-xe )79138 alloys exhibit usual characteristics of spin glasses : freezing temperatures T (sharp cusp in zero-field susceptibility) proportional to x up to x=4 at. %. However, the magnetization does not follow the Blandin-Souletie-Tournier scaling laws. Such an anomaly can be explained within a model of ferromagnetic clusters coupled bt RKKY interaction. INTRODUCTION.From...

A pre-phylogenetic revision of the family Phalacridae at the genus level is presented. Twenty-eight new generic synonymies are established as follows: Acylomus Sharp 1888 (=Liophalacrus Sharp 1888, syn. nov.; Ganyrus Guillebeau 1894, syn. nov.; Podocesus Guillebeau 1894, syn. nov.; Tinodemus Guillebeau 1894, syn. nov.; Ledorus Guillebeau 1895, syn. nov.; Astenulus Guillebeau 1896, syn. nov.; Af...

See related article, page 137. In 1977, Sourander and Walinder1 described a family with neuropsychiatric disease, a relapsing course, and cognitive impairment. The disorder began in early adulthood, affected women and men, and lasted for 10 to 15 years. At brain necropsy, there were multiple small infarcts, particularly of the basal ganglia, thalamus, periventricular white matter, and pons. Vas...

Introduction: Diffusion-weighted, readout-segmented EPI (rs-EPI) with parallel imaging and 2D navigator correction [1] can provide substantially improved image quality compared to single-shot EPI (ss-EPI) with parallel imaging. The technique achieves a reduction in susceptibility artefacts and T2 image blurring by allowing a very short echo-spacing, which unlike ss-EPI does not increase with th...

INTRODUCTION: Diffusion tensor MRI (DT-MRI) has been useful in estimating microscopic changes in tissue based on water molecular diffusion. However, DT-MRI is inappropriate in regions with non-parallel fibers [1]. To overcome this, high angular resolution diffusion (HARD) encoding schemes have been proposed [2] and used for finite mixture of Gaussians [2], q-Ball imaging [3] and spherical decon...

Introduction In recent years Spherical Deconvolution (SD) methods have been applied to diffusion imaging to improve the visualization of multi-fibre orientation in brain regions with complex white matter organization [1][2][3]. However, the potential to quantify white matter integrity with SD has not been explored. Previous simulations have shown that the variation of fibre diffusion properties...

We advocate to shift research efforts in environmental biotechnology from searching for desired traits of monocultures that microbial communities. As these will be hard identify with classical genome mining approaches, we recommend using artificial community selection as a tool and select novel and/or enhanced functions.Bioremediation biodegradation artificially selected communities harbors gre...

The Extramedullary Plasmacytomas (EP) are rare tumors originating from plasmacells of the soft tissues outside of the bone. For a correct diagnosis biopsy is mandatory and CT or MRI is necessary. We report a case of a 62 year-old man, who underwent to otolaryngologist visit for nose bleeding. A peduncolated right palatine tonsillar lesion was diagnosed. The nasopharyngeal examination revealed a...
