A public process has been in place in the United States for six years to establish an HDTV terrestrial broadcasting standard. The process, having moved through a planning phase, a competition phase, and an examination phase, has now entered a cooperation phase. Remarkable progress has been made — a testament to the process. During the next few months, the American digital HDTV terrestrial broad...

The present study aimed to assess the environmental fate of the insecticide and nematicide ethoprophos in the soil-water interface following the pesticide application in simulated maize and potato crops under Mediterranean agricultural conditions, particularly of irrigation. Focus was given to the soil-water transfer pathways (leaching and runoff), to the pesticide transport in soil between pes...

The article provides information about a new device, AlgaTox developed in the R&D project sponsored by the Technology Agency (n.TA02030179) and patented in Czech Republic (CZ 305687). Its functionality is based on the use of biosensor, and its main advantage is fast response rate. The toxicity detection is achieved through precise measurement of green algae oxygen production dynamics after thei...

Abstract. Oxidative stress can be used to evaluate not only adverse health effects but also ecological effects, limited research uses eco-toxicological assay assess the risks posed by particle matters non-human biomes. One important reason might that concentration of toxic components atmospheric particles is far below high detection limit eco-toxic measurement. To solve rapid problem, we extend...

In this paper a comparative study of two measurement campaigns carried out in Barcelona, Spain, and Pozna , Poland, to identify spectrum occupancy in different bands, is presented. In both cases the measurement setup was harmonized to obtain comparable results. The problem of efficient noise floor estimation was also considered and a pragmatic approach that takes into account both internal and ...

Gas products from gasified solid recovered fuel (SRF) have been proposed as a replacement for natural gas to produce electricity in future power generation systems. In this work, the life cycle assessment (LCA) of SRF air gasification energy was conducted using Recipe2016 model considering five environmental impact categories and four scenarios Qatar. The current situation municipal waste (MSW)...
