Composting and digestion are important waste management strategies. However, the resulting products can contain significant amounts of organic pollutants such as polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs). In this study we ...
This study uses an endogenous switching-regression model to examine the impact of slash-and-burn cultivation practice on the application of commercial fertilizer and pesticides, as well as yields and net returns. The empirical evidence of the study indicat ...
The first series tube of the gyrotrons for the 10-MW electron cyclotron resonance heating system of the stellarator W7-X was tested at Forschungszentrum Karlsruhe (FZK) and yielded a total output power of 0.98 MW, with an,efficiency of 31% (without a singl ...
This article presents a power-efficient and low-voltage CMOS output driver circuit based on low-voltage differential signaling (LVDS) standard. To reduce the ringing at the output of the proposed driver circuit and simultaneously keep the power consumption ...
In this paper we explore the concept of informal innovation by investigating it both on the input (activities) and output (impact) side of the innovation process. Informal innovation is defined as innovation that is not explicitly planned and budgeted and ...
This paper deals with the modeling of the strategic allocation of greenhouse gases emission allowances in the EU-wide trading market that results from Kyoto agreement implementation. An M-matrix game is formulated where the players are countries or groups ...
In this paper, we present a model-checking toolset for a synchronous version of the Java language (Synchronous Java or in short sJava). The toolset includes a set of extensions to the Bandera and Bogor model-checking frameworks. It inherits thus a large nu ...

Introduction In 1987, the need to strive towards development aimed at making it possible to satisfy the present needs without compromising the needs of future generations is generally acknowledged. The Rio Earth Summit in 1992 propagated Agenda 211, whi ...
Emergy (spelled with an m) is the energy of one kind, usually solar energy, which is required to make a service or product. The yearly emergy consumption/production of a building is evaluated considering the Solar Energy Laboratory (LESO) building on the c ...
Eutrophication of various lakes on the Swiss Plateau was targeted in the 1980s by reducing external nutrient loading and installing aeration/oxygenation systems. For five eutrophic lakes, three of which have been artificially oxygenated and aerated for alm ...
