The results show that the Aharonov-Bohm flux have an effect on the peak, the width, the energy and the spatial configuration of the spin of the soliton.展开更多

Aspergillus spp. is one of the agents.Fungi of aspergillus genus are widely distributed in nature, particularly in the soil and in thedecomposed vegetation. They are frequent opportunist pathogens in immunocompromised patients. Themost frequent causative organisms that cause cutaneous aspergillosis are A. fumigatus and A. flavus.In this report, we present a case of primary cutaneous aspergillosis manifested by ulceration ofthe shank due to A. flavus. The patient had no deficiency of immunological status and severe diseaseassociated with fungal infection. Excellent response was shown to anti-fungal therapy.展开更多
