Spinal fluid lactate dehydrogenase (L.D.H.) isoenzyme patterns have been investigated in normal subjects, in those with non-destructive nervous disease, and in those with destructive lesions in the nervous system.The spinal fluid from organic disease in general showed a significantly increased level of L.D.H.(2) and L.D.H.(3) so that the combined values of L.D.H.(2) and L.D.H.(3) might perhaps ...

Accelerated Destructive Degradation Tests (ADDTs) provide reliability information quickly. An ADDT plan specifies factor level combinations of an accelerating variable (e.g., temperature) and evaluation time and the allocations of test units to these combinations. This paper describes methods to find good ADDT plans for an important class of destructive degradation models. First, a collection o...

Many long established US DOE facilities are in possession of poorly documented wastes in a variety of forms spanning a broad range of waste containers, waste matrices and isotopic mixtures. Existing assay technologies such as the SuperHENC can address many of the expected waste configurations. However, there are also expected waste items that fall outside the normal operating range of these exc...

Policy interest since the early 1980s has focused in different ways on the creation of a large, productive, taxable economy – in which entrepreneurship plays a role for employment, income growth and innovation. The current understanding of various forms of entrepreneurship remains incomplete, focusing largely on productive and unproductive entrepreneurship. However, destructive entrepreneurship...

PURPOSE To report the clinical and histopathologic findings of a patient with sarcoidosis causing bilateral destruction of the lower eyelids. METHODS Case report. RESULTS Bilateral destructive lower eyelid lesions and cicatricial entropion developed in a 43-year-old man with systemic sarcoidosis. Histopathology was consistent with sarcoid granulomas. Disease progression was arrested with sy...

An increasing number of marine structures are utilizing composite materials. Major structure and components can be built lighter and corrosion-resistant using composite construction. The recreational boating industry has long recognized this and now commercial ferries are increasingly realizing fuel savings through weight reduction. The US Navy’s DDG-1000 topside structure and LPD-17 advanced e...

BACKGROUND Non-Inflammatory Destructive Periodontal Disease (NIDPD), is a severe destructive periodontal disease, that is characterized by the attachment loss and alveolar bone loss, without signs of the gingival inflammation, and the periodontal pocket development. OBJECTIVE Despite the fact that various cases of NIDPD have been reported; their etiology and disease evolution is still indefin...

John S. Popovics Summary Lasers are devices that create a high intensity, directed light beam. The light beam can travel in air or through fiber optic cables. Lasers can be used to generate waves and detect stretching or motion in a solid material without direct contact with the material. Thus lasers are useful in many important engineering applications that require remote non-destructive evalu...
