Fifteen compounds reported to be inhibitors of gelation or sickling were studied by standard methods. These tests included (1) the determination of the solubility of deoxyhemoglobin S or Csat, (2) evaluation of sickling in whole SS blood at various pO2s, (3) measurement of the oxygen affinity of hemoglobin and blood, and (4) examination of red cell indices and morphology. Among the 4 noncovalen...

Abstract Brittleness is a crucial parameter of rock mass and the key indicator in engineerings, such as rockburst prediction, tunnelling machine borehole drilling, hydraulic fracturing. To solve problem using present brittleness indexes, existing indexes were firstly summarised this paper. Then, index (BL), which considers ratio stress drop rate increase peak stress, was proposed. This new has ...

This paper presents a novel Bayesian-based method for predicting brittleness. The involves synthesizing petrophysical data from multiple well cores to establish joint Gaussian distribution function shale facies and non-shale facies. Furthermore, Bayesian classification is applied seismic data. proposed combines with Rickman brittleness obtain new index. are utilized enhance the differentiation ...
