Life cycle assessment and economic analysis of a low concentrating photovoltaic system.

Many new photovoltaic (PV) applications, such as the concentrating PV (CPV) systems, are appearing on the market. The main characteristic of CPV systems is to concentrate sunlight on a receiver by means of optical devices and to decrease the solar cells area required. A low CPV (LCPV) system allows optimizing the PV effect with high increase of generated electric power as well as decrease of active surface area.

An Italian-Australian comparison of quality of life among people with intellectual disability living in the community.

This paper reports the measurement of both objective and subjective quality of life in samples of people either with intellectual disability or from the general adult population, drawn from Australia and Italy. Measures were made using the Comprehensive Quality of Life Scale. Generally, it was found that the scores for all groups were comparable.

Isolated myoclonic alien hand as the sole presentation of pathologically established Creutzfeldt-Jakob disease: a report of two patients.

Creutzfeldt-Jakob disease may have many atypical presentations before the development of classic progressive dementia and startle myoclonus. In two patients with pathologically established disease association with a progressive alien hand syndrome was the sole initial manifestation of the disease.

Homonymous field defect as the first manifestation of Creutzfeldt-Jakob disease.

Purpose: Although in the early stage of Creutzfeldt-Jakob disease most patients have obvious dementia, we found that the disease can be diagnosed in patients solely on the basis of a visual system disorder.

Methods: We examined three patients who initially complained of a nonspecific, insidious visual disturbance.

Results: The three patients were found to have Creutzfeldt-Jakob disease, confirmed by histopathologic analysis.
