Creating an effective parallel SAT solver is known to be a challenging task. At present, the most efficient implementations of parallel SAT solvers are portfolio solvers with some heuristics to share learnt clauses. In this paper, we propose a novel approach for solving SAT problems in parallel based on the combination of traditional CDCL with St̊almarck’s method. In particular, we use a variant...
Recovering resources from water purification sludge (WPS) have been gradually stipulated in environmental protection laws and regulations in many nations. Hence, reusing the WPS is becoming an important topic, and recovering alum from WPS is one of the many practical alternatives. Most previous research efforts have been conducted on studying the amphoteric characteristic of aluminum hydroxide ...
ethylammonium propionate with high polarity and ionic conductivity was synthesized andcharacterized with 1hnmr and ir. this ionic liquid which is prepared from readily available startingmaterial in high yield shows reasonably high at viscosity and heat stability up to 150 °c. this ionicliquid is able to dissolve most of organic solvents due to the hydrogen interaction between ionicliquid and th...
A model was developed to aid in the selection of healing monomers that can rapidly dissolve catalysts in self-healing materials. Predictions are made regarding dissolution rates of Grubbs’ catalyst in a small library of ring-opening metathesis polymerization (ROMP)-active norbornenyl-based healing monomers. The Grubbs’ catalyst and the healing monomers were experimentally assigned sets of Hanse...
1. Protein fractions derived from tubercle bacilli are toxic to the interior of Amoeba dubia but have no action on the plasmalemma. 2. Phosphatide fractions dissolve the plasmalemma but have no effect on the internal cytoplasm. 3. The fatty acid fraction has a marked solvent action on the plasmalemma when brought in contact with the surface of the cell. When injected it may slowly penetrate the...
this study illustrates the process of removal of chromium from chrome tanning waste-water by fly ash which was drive from chrome shaving dust. this experiment was carried out in a batch process with laboratory prepared adsorbent samples and chrome tanning water collected from local tanneries. the influence of various factors likes adsorbent doses, contact time, and initial concentration of chro...
