Characteristics of families with a negative net worth are explored using data from the 1992 Survey of Consumer Finances. Life cycle theory is applied to predict which households have a negative net worth. Logit analysis showed that well educated young households who might expect increasing...

BackgroundAs a crucial component of solar radiation, the association between exposure to ultraviolet (UV) radiation and acne remains unclear.ObjectivesTo investigate the association of previous exposure to ultraviolet radiation at different wavelengths or doses with acne in college...

To accurately predict the gravity separation distribution rate and thus the product yield during the design and management of coal preparation plants, a modified hyperbolic tangent model was proposed to derive direct calculation formulas for heavy-medium and water-medium separation distribution...

Dielectric barrier discharge (DBD) synergistic catalysis technology combines the high reaction activity of a plasma and the high reaction selectivity of a catalyst and has attracted increased attention in recent years. In this work, the conversion of carbonyl sulfide (COS) by DBD combined with a...

A new process of “cold spraying interlayer + roll-bonding” (CSIR)for preparation of metal clad plates was put forward. Firstly, micro-Ni particles were cold sprayed to form an ultra-thin coating between two substrate slabs. Then the elongation and bonding of Mg and Al substrate slabs and...

Constructing acceptor–donor units (D/A) of polymer is an efficient method for promoting carrier separation to optimize photoreactivity. However, the carriers across the D/A interface of micromolecule was relatively hindered by the Coulomb potential. In this work, the polarity-bridged...
