To monitor the stage in turbid reservoirs with a sloping bank, it has been proposed to install a near-infrared Lidar on the bank and to orient it so that it points at the water surface with a large incidence angle (between ≈ 30◦ and 70◦). The technique assumes that the Lidar can detect suspended particles that are slightly below the water surface. Some laboratory results and the first long-term...

The biliary excretion and blood/plasma ratios of four novel 5-bromo-6-alkoxy- 5,6-dihydro prodrugs to S-ethyl-2'-deoxyuridine (EDU) including (-)-trans-(5S, 6S)-S-bromo-S-ethyl-6-methoxy-S, 6-dihydro-2'-deoxyuridine (BMEDU), (+ )-trans( SR, 6R)-S-bromo-S-ethyl-6-ethoxy-S, 6-deoxyuridine (BEEDU), (+ )-trans-(SR, 6R)-5-bromo-5-ethyl-6-ethoxy -S, 6-dihydro-S '-O-valeryl-2 ':.deoxyuridine (VBE...

Europe is currently transitioning to digital terrestrial television and is aimed to replace all analog infrastructures by 2012. Besides replacing all broadcasting networks in Europe, the transition requires updating household televisions and antennas. As with any major change, public administrations must keep citizens informed and provide support, especially when dealing with a communication me...

Digital television (DTV) provides pedagogical and technological advantages to education. DTV is presented as a novelty for the audience and involves the convergence of education, telecommunications, and internet in a unique environment. This technology will allow for the development of interactive educational platforms known as t-learning platforms. Currently, there are relatively few models wh...

Determination of activity concentrations in twenty five (25) soil samples collected from various points in bauxite ore deposit in Menoua Division in Western of Cameroon was done using gamma spectrometry based Broad Energy Germanium (BEGe6530) detector. The average terrestrial radionuclides of (40)K, (226)Ra, (232)Th, (235)U and (238)U were measured as 671 ± 272, 125 ± 58, 157 ± 67, 6 ± 3 and 99...

Soil acts as a source of continuous radiation exposure to human and as a medium of migration for transfer of radionuclides to the biological systems hence causes the radiological contamination in the environment. So, it is necessary to study the natural radioactivity in soil to assess the dose due to terrestrial gamma radiation levels in order to know the health risks. The Primordial Radioactiv...

One of the tasks of the European Commission (EC) under the Euratom Treaty is to collect, validate and provide information about the levels of radioactivity in the environment. In order to offer to the public a more balanced view on the annual dose that it may receive from environmental radioactivity, a few years ago we decided to explore the feasibility of preparing a European Atlas of Natural ...
