Post-stratification weights were used to correct for over- and underrepresentation in response. Adjusted logistic regression was used to model associations with early sexual experience, by gender. In the final sample ( N =5,321, 49% girls), 9 in 10 were sexually experienced, of whom 21% ...
moist neutral stratification 中尺度对流系统CloudSat卫星湿中性层结Many vertical sections of Mesoscale Convective System (MCS) detected by CloudSat satellite in regions of high humidity have a structural trait whereby the equivalent potential temperature is close to uniform in the vertical. This is called...
Stratification. Stratification means trying to keep the levels of decomposition stratified so that you can view the system at any single level and get a consistent view. Design the system so that you can view it at one level without dipping into other levels. Standard techniques. The more a s...
What system of stratification is commonly used in capitalist societies? What is an economic goal that Marxism shares with socialism? What are the major characteristics of fascism? What are the main economic system models? What is a free economic system?
and in some instances even skin-type differentiation, showing striking similarities not only in morphology but also in terms of gene expression. Therefore, characterization of this dynamic process lends insight into the process of stratification, squamous cell formation, and “keratinization” in a path...
Based on the description of the origin and growth of natural convection,the mechanism and development of cryogenic liquid thermal stratification were analyzed.The precondition of thermal stratification and the dominant factor of effecting on stratification ratio were explained combining with the cryogenic th...
Real-world data were employed to determine clinical characteristics of patients with myasthenia gravis (MG) with differing degrees of muscle weakness, as defined using the Myasthenia Gravis Foundation of America (MGFA) classification system. Data were dr
It can be explained that the particle size classification results in the 200 m high bench dump forming a clear horizontal stratification. The top of the dump site comprised a relatively less coarse grain content, the middle of the dump site was moderately distributed, and the bottom content of...
To investigate the dynamic mechanical behavior and energy dissipation characteristics of low-temperature rock samples under cyclic impact loading, a temperature-controlled impact system that combines Hopkins bars with a low-temperature compensation devic
However, owing to thermal buoyancy, introducing warm air may result in large temperature stratification and/or airflow short-circuiting between supply inlet and exhaust outlet [7,9]. Such problems, which counteract thermal comfort and energy saving, often occur in a room that is heated through ...
