For n ≥ 2 let ∆ be a Dynkin diagram of rank n and let I = {1, . . . , n} be the set of labels of ∆. A group G admits a weak Phan system of type ∆ over C if G is generated by subgroups Ui, i ∈ I , which are central quotients of simply connected compact semisimple Lie groups of rank one, and contains subgroups Ui,j = 〈Ui, Uj〉, i 6= j ∈ I , which are central quotients of simply connected compact s...

Oral lichen planus (OLP) has a prevalence of approximately 1%. The etiopathogenesis is poorly understood. The annual malignant transformation is less than 0.5%. There are no effective means to either predict or to prevent such event. Oral lesions may occur that to some extent look like lichen planus but lacking the characteristic features of OLP, or that are indistinguishable from OLP clinicall...

The Schedule for Affective Disorders and Schizophrenia (SADS), Part I, and the Present State Examination (PSE) are both structured interviews to assess the present psychiatric condition. The present article attempts to provide researchers with information that may help them to decide which of the two instruments would be most suitable for their purposes. We describe the similarities and differe...

Today's environment has different impacts on our body than previous generations. Heavy metals are a growing concern in medicine. Doctors and individuals request the removal of their amalgam (silver mercury) restorations due to the high mercury content. A safe protocol to replace the silver mercury filling will ensure that there is minimal if any absorption of materials while being removed. Stro...

The wear of cental amalgam was studied by single- and double-pass sliding and by a silicon carbide abrasion test. A dispersed amalgam showed significantly better resistance to two-body abrasion than the spherical amalgams tested. The wear amalgam was determined by resistance to penetration and by a ductile mode of surface failure over the load range studied. Differences in the wear of amalgam a...

Policy debates over medical malpractice in the United States involve a complex amalgam of legal doctrine, public demands to address the problem of medical errors, and the interests of various stakeholder groups. Most parties can agree, however, that the current system for compensating medical injury performs poorly. It falls short of achieving its two main goals: compensation and deterrence. Th...

This paper discuss an image presenting method that projects information on an inner wall of a car in order to raise safety by using RPT(Retro-reflective Projection Technology). In previous research, we can see through the rear seat which is covered with retro-reflective material as a screen and recognize directly backward of a car. In this paper, we propose a projection optical system for binoc...
