primary assumption in most problems of elasticity theory in petroleum geophysics is that the elastic media is isotropic. laboratory experiments confirmed that most rocks are anisotropic. if in one medium, properties vary with directions, it is named as anisotropic. knowledge about anisotropy reduces risk and cost of hydrocarbon production. in the present study, anisotropy of a carbonate reservo...

The aim of this study was to stratify 305 elderly (> 65 years) treated at an academic health center (Botucatu, São Paulo, Brazil) according to risk of repeated hospitalization. Data collection used an instrument to evaluate risk of repeated hospital admissions, including eight health indicators: self-rated health, hospitalizations, doctor visits, diabetes, cardiovascular disease, gender, social...

Based on global cardiovascular (CV) risk assessment for example using the Framingham risk score, it is recommended that those with high risk should be treated and those with low risk should not be treated. The recommendation for those of medium risk is less clear and uncertain. We aimed to determine whether factoring in chronic kidney disease (CKD) will improve CV risk prediction in those with ...

This paper has combed the research results on internal control of small and medium manufacturing enterprises of domestic and foreign scholars. Combined with the status analysis of internal control and risk management of small and medium manufacturing enterprises, this paper built the internal control framework of small and medium manufacturing enterprises based on comprehensive risk management ...
