introduction atmospheric processes and their interactions with ground surface responsible for formation and evolution of a heavy dust storm are important for identifying dust transport pathways. spatial and temporal distribution of middle eastern dust for a severe dust event during 4-8 july 2009 was analyzed by weather research and forecasting with chemistry (wrf/chem) model simulations, in-sit...

solitary plasmocytoma is rarely located in the cranial vault. we report one case of solitary plasmacytoma of the skull and discuss the clinical features and treatment of this uncommon tumor in the light of the published cases. a 46-year-old moroccan male, without previous history consulted for a swelling in medial frontal and paramedian region. on clinical examination the clinical examination r...

One of the most important factors in drug addiction is stress. It has been shown that animals with prenatal stress history are more risky for drug dependence. It have also been shown that frontal cortex play a role in drug dependence. In the present study the effects of two kinds of mild stress during pregnancy on the development of frontal cortex in Wistar rats (250-300 g) were investigated. F...

A case of frontal sinusitis with osteomyelitis its posterior wall producing lobe brain abscess is presented, whereby the dehiscence was exposed by external sinostomy an ENT surgeon and then, through dehiscence, drained a neurosurgeon. This uncommon technique draining where no bone craniotomy required. approach yields least damage to cerebral tissue as very close sinus drain has travel minimal i...

The world is an unpredictable place, presenting challenges that fluctuate from moment to moment. However, the neural systems for responding to such challenges are far from fully understood. Using fMRI, we studied an audiovisual task in which the trials' difficulty and onset times varied unpredictably. Two regions were found to increase their activation for challenging trials, with their activit...

We examined interactions between frontal, striatal, and hippocampal systems during a rule-learning task. Nineteen healthy young adults solved multiple rule-learning problems requiring hypothesis testing while functional magnetic resonance images were obtained. Activity in the head of the caudate peaked early after the beginning of each problem and then dropped rapidly. In contrast, activity in ...

Pronounced environmental trends across fronts suggest that the otolith chemistry of oceanic fish can resolve zones on either side, promoting application to population questions at similar spatial scales. Trace and minor elements laid down immediately prior to capture—along the edges of otoliths from Patagonian toothfish Dissostichus eleginoides—discriminated frontal zones in the Antarctic Circu...

Markerless motion capture systems have developed in an effort to evaluate human movement in a natural setting. However, the accuracy and reliability of these systems remain understudied. Therefore, the goals of this study were to quantify the accuracy and repeatability of joint angles using a single camera markerless motion capture system and to compare the markerless system performance with th...

Research on biometrical systems and especially on face recognition systems has become of high interest. Nowadays several approaches exist to recognize frontal views of faces. Under certain constraints the recognition accuracy even for huge databases seems to be acceptable. However, it has shown, that the recognition performance of nearly all state-of-the-art systems dramatically drops down, whe...
