We investigate the system of D-dimensional hard spheres in D-dimensional space, where D>3. For the fluid phase of these hyperspheres, we generalize scaled-particle theory to arbitrary D and furthermore use the virial expansion and the Percus-Yevick integral equation. For the crystalline phase, we adopt cell theory based on elementary geometrical assumptions about close-packed lattices. Regardle...

Neste trabalho são discutidos os resultados de uma sequência didática baseada no método Peer Instruction para o ensino de circuitos elétricos, aplicada em sete turmas de ensino médio integrado a cursos técnicos. Os dados obtidos, em dois testes iguais, antes e depois da aplicação do método, foram analisados a partir do ganho normalizado ou ganho de Hake, e comparados a trabalhos na literatura n...

Presented here is a computational system which uses free−space optical interconnect (FSOI) communication between processing elements to perform distributed calculations. Technologies utilized in the development of this system are integrated two−dimensional Vertical Cavity Surface Emitting Lasers (VCSELs) and MSM−photodetector arrays, custom CMOS ASICs, custom optics, wire−bonded chip−on−board a...

was to assess analytical issues surrounding the measurement of PSA in prostate cancer screening. A subsequent review article published earlier this year in the Annals of Clinical Biochemistry titled " Pre-and post-analytical factors that may influence use of serum prostate specific antigen and its isoforms in a screening programme for prostate cancer " 1 discusses the findings and draws from th...
