The present invention relates to an apparatus and method for clinical decision support to identify patients at high risk of thrombosis based on a combination of clinical risk factors and molecular markers, e. The method includes grinding of the carbon nano-materials. Also described is a method for staggercasting. In particular, without mapping information, software and hardware modules cannot access and modify the contents of trusted memory sections. The resection instruments preferably engages and locks to said engagement members via a sliding rod engagement member. , grinding and sieving the sludge through a screen to obtain sludge ash, forming the sludge ash into an artificial sludge aggregate by mixing the sludge ash with an inorganic binder and water followed by granularizing, and mixing the artificial sludge aggregate with an inorganic binder and water to form the sludge aggregate concrete product.
