Recent studies have highlighted the ecological, economic and social benefits assured by green roof technology to urban areas. However, green roofs are very hostile environments for plant growth because of shallow substrate depths, high temperatures and irradiance and wind exposure. This study provides experimental evidence for the importance of accurate selection of plant species and substrates...

We have investigated developmental alterations in the tonotopic projection of the gerbil lateral superior olive. Single neurons were characterized in the frequency domain and the recording site marked with fast green. Transverse tissue sections from the auditory brainstem of each animal were visualized with a video-equipped microscope, and the image was digitized for subsequent alignment. The t...

We have constructed a sequence of solutions of the Helmholtz equation forming an orthogonal sequence on a given surface. Coefficients of these functions depend on an explicit algebraic formulae from the coefficient of the surface. Moreover, for exterior Helmholtz equation we have constructed an explicit normal derivative of the Dirichlet Green function. In the same way the Dirichlet-to-Neumann ...

In this paper, we analyse the financial viability and economic sustainability implications of government programs for the development of renewable energy sources, explicitly considering that consumers take environmental issues into account. We envisage a broad policy strategy for the future, which we label the “World Sustainable Scenario”, and we quantify the inter-temporal resource requirement...

The increased pollution arising from different stages of producing, distributing, and disposing of electronics products highlights the importance of green operations (GO) in terms of process and product stewardship to mitigate environmental damages and satisfy the escalating social expectation for environmentally friendly operations in the electronics industry. Drawing on the natural-resourceba...

In recent years there has been a considerable increase in our knowledge of the respiratory metabolism in higher plants. The lower plants, however, have received little attention. This is particularly true of the blue-green algae where the amount of available information on their respiration is almost negligible. The only known investigation has been that of EMERSON (1) who reported that respira...

Under sustainable development pressures, organizations have to consider the relationship between the environment and activities of supply, production, distribution, consumption and disuse, which is known as “green supply chain management” (GSCM). The article presents an overview of research work in these areas, followed by an introduction of the green concept in SCM resorting to System Dynamics...

Recent developments in climate concern have lead to changes in technology to reduce energy consumption in order to decrease green house gas emissions, as well as cost reduction. One of the methods (re)introduced is virtualization. Virtualization makes it possible to consolidate multiple operating systems on one hardware platform, making utilization of hardware resources more efficient. This res...

1. The fast green stain of Alfert and Geschwind for nuclear basic protein is shown to obey the Beer-Lambert laws when used on purified histone. Interference from acid substances other than nucleic acids as a possible source of error is indicated. 2. Use of this technique after a modified Feulgen stain enables determination of relative amounts of desoxyribonucleic acid and histone in the same in...
