The CE mark is compulsory since 2002 for every kind of manhole step (steps for construction sector) following the UNE-EN-13101 European Norm and without this marking, nobody can manufacture or commercialize in Europe. Manhole steps are a complementary product in the civil works and clients usually do not know or ask for the norms. However, this product implies a very important detail in the ...
Pleistocene megafloods generated several large-scale obstacle marks that could not be interpreted hydraulically with the present knowledge of submerged obstacles. Thus, flume and field data of classical obstacle marks, characterised by a frontal scour hole and an adjacent depositional ridge, are analysed to estimate flow velocities from obstacle mark geometry, especially scour depths, length, ...

Pre-Construction Surveys The VIY2-300 GPR was used to survey Korolenko Square and contiguous area in Rivne town from 5 to 6 December 2006. Surveys were carried out both on the lawns and reinforced paving slabs. Large building structures, presumably ruined bridge foundation, are marked in blue. River at this place is no more than 100 years. Large buried objects are marked in blue. The deeper ...
Environmental and engineering firms often are tasked with performing soil borings for monitor well installation as part of a Phase II Environmental Site Assessment. This task becomes more challenging when the borings are to be installed in gasoline stations, right of ways or other areas where there are numerous underground utilities that are either unmarked or not properly located. GeoView can ...
Small constructed wetlands for up to 50 PT built in series are subject to two different fields of law. To place the product on the European market the construction law has to be respected and the product usually needs to be CE-marked. To operate such a plant and discharge the treated wastewater, the national water law needs to be respected and in some countries national approvals are ...

Introduction Water is an important substance without which mankind cannot survive. However, it also causes problems such as residual impurity in scientific experiments and in manufacturing processes where a high-vacuum condition or a high-purity gas is required. This is because water is present in the atmosphere in large quantities and therefore can intrude readily everywhere, and can adsorb ...
The research described here was performed to define curves of subjective equivalence between steering wheel rotational vibration and sound using stimuli from different automobile operating conditions. The steering wheel acceleration stimuli were summarised in terms of the unweighted and Wh weighted r.m.s. values, while the sound stimuli were summarised in terms of the unweighted SPL in decibels, ...
Sublethal levels of pollutants usually cause biochemical or physiological effects at the subcellular level in an organism. Death is too extreme a criterion for determination of whether a substance is harmful or not; it is therefore important to find biomarkers of health and sublethal toxicant effects. In the 11 local-government areas of Ibadan, a large metropolitan area in Nigeria, previous ...
Since the commissioning of the 'El Cabril' Central Storage Facility for Low– and Intermediate–level Radioactive Waste (hereafter 'El Cabril'), most people living in nearby towns and villages have regarded this nuclear facility with a marked degree of rejection and distrust. This study examines the process of analysis, management and intervention specifically designed and implemented with a view ...

Histone H3 tail modifications are among the earliest chromatin changes in the X-chromosome inactivation process. In this study we investigated the relative profiles of two important repressive marks on the X chromosome: methylation of H3 lysine 9 (K9) and 27 (K27). We found that both H3K9 dimethylation and K27 trimethylation characterize the inactive X in somatic cells and that their relative ...
