1. The cycle groups C8. An algebraic variety F i n w-dimensional complex projective space P ( n ) is obtained by equating to zero a finite number of forms Fi(x0, • • • , xn)f • • • , Fm(xo, • • • , xn) with complex coefficients ; F is assumed to be nonempty. If F i s irreducible, that is, if V is not the union of a finite number of proper subvarieties, it is possible to associate with V in seve...

The objective of this work was to study the corrosion behavior 2xxx aluminum alloys in marine environment and degradation mechanical properties caused by as well provide support for lightweight design equipment. characteristics 2297-T8 2195-T8 were observed scanning electron microscopy (SEM) energy dispersive spectroscopy (EDS) at 3, 6, 9, 12 months exposure, obtained via uniaxial tensile testi...

A case of extramedullary spinal root hemangioblastoma is described. A 44-year-old male presented with gait disturbance. Magnetic resonance (MR) imaging revealed a round enhanced mass at the level of T8. Spinal angiography showed a vascular tumor fed by the posterior spinal artery via the left T9 intercostal artery. A laminectomy of T8-T9 was performed, and a reddish brown-colored soft tumor ori...

The haematological profile and peripheral blood lymphocyte subpopulations of 36 patients with donovanosis were estimated by an indirect immunofluorescence technique using monoclonal antibodies. Concentrations of serum immunoglobulins (IgM, IgG, and IgA) were also estimated. The total leucocyte and lymphocyte counts were generally raised, as were total T lymphocyte, T4, and T8 counts. Patients w...

STUDY DESIGN  Case report. OBJECTIVE  To describe a case of spinal cord transection in a 6-year-old child. BACKGROUND INFORMATION  Non-missile injury of the spinal cord is not common and its incidence varies according to the country. In addition, to our knowledge, there are no published reports of spinal cord injury (SCI) from a penetrating nail. Here, we report the case of a child who deve...
