Perfect and internal control, and can be effective for control and supervision of the exercise of power. From this analysis of the current organizational structure and internal control of the building status quo and the existence of the problems, and in response to these issues put forward a number of points, and measures to reduce public institutions internal accounting control risk has a positive role.展开更多

Methods which make such a complex characterization possible are rare. This paper presents an investigation carried out at the University of Mons （Belgium） in collaboration with the technical support and control unit, restoration directorate, of the Walloon region, aiming to evaluate the effectiveness of consolidants used to strengthen stone masonry. The characterization of the materials is based on a novel semi-destructive scratching method which allows tomographic representation of the strength of the damaged and treated areas. This paper describes the experimental methodology and presents results from laboratory experiments as well as a case study.展开更多
