Irradiation of the posterior segment of the eye resulting from radiotherapy either of local ocular lesions (e.g. retinoblastoma or malignant melanoma of the choroid) or of extraocular lesions of the adjacent regions (e.g. carcinoma of the antrum and nose, rodent ulcer of the face, squamous cell carcinoma of eyelids, etc.) has been known to produce delayed retinal vascular changes which develop ...

Examination of research into pole alternatives indicates that, without exception, studies have found that total energy requirements associated with wood materials are considerably lower than those of commonly substituted materials. The substitution of high-energy-intensive materials for low-energy-using wood materials would contribute substantially to an overall increase in carbon

The rise in the average temperature of earth has been described as global warming which is mainly attributed to the increasing phenomenon of the greenhouse effect. It is believed that global warming can have several harmful effects on human health, both directly and indirectly. Since malaria is greatly influenced by climatic conditions because of its direct relationship with the mosquito popula...

[1] The accumulation of wind blown (eolian) dust in deep‐sea sediments reflects the aridity/humidity conditions of the continental region supplying the dust, as well as the “gustiness” of the climate system. Detailed studies of Pleistocene glacial‐interglacial dust fluxes suggest changes in accumulation rates corresponding to orbital variations in solar insolation (Milankovitch cycles). While t...

This paper presents a tool for mapping several commonly available novel controllers to various musical parameters in order to provide technological novices with a way to exploit new forms of musical interaction provided by technology. The tool automatically connects to a control interface specified by the user and maps input parameters of that interface to musical output. Besides being able to ...

CONTINUED ON PAGE 5 California has drawn much international attention with its efforts to reduce greenhouse gases and encourage clean electricity production. In addition to pre-existing regulations that require expanded energy efficiency programs and increased purchases of renewable energy, last year California passed Assembly Bill 32 which calls for an overall reduction in greenhouse gases to ...

This study discusses a Turkish music education model similar to its Venezuelan counterpart El Sistema, in which socialization and human development are the main goals. The Music for Peace (Baris Icin Muzik) model, founded in 2005 by an idealist humanitarian in Istanbul, started as a pilot project with accordion and today makes symphonic music education. The program aims to offer social change t...

Contemporary societies are faced by a new spectre haunting the 'globe' – the changing of the world's climate. Such change is believed to be caused by increased levels of ‘greenhouse gases’ (GHGs) in the atmosphere which cannot be fully absorbed into the oceans and hence impact upon the earth’s present and future temperatures. Such a climate forcing mainly results from systems that involve extra...

[1] The African Sahel experienced severe drying between the 1950s and the 1980s, with partial recovery since. We compare Sahel rainfall in the 20th century, pre-industrial, and increased greenhouse gases (GHG) simulations produced for the Intergovernmental Panel on Climate Change (IPCC). The simulations forced by 20th century concentrations of aerosol and GHG reproduce (i) a global change in SS...
