A knowledge of the solubility of 3,4-bis(3-nitrofurazan-4-yl)furoxan (DNTF) in different solvents is essential for crystallization and further theoretical studies. The laser monitoring system was used for measuring the solubility of DNTF in methanol, ethanol, acetic acid, benzene, toluene and n-butanol at temperatures ranging from (298.15 to 338.15)K. Polynomial empirical equation, ideal model and...
A novel pattern diversity slot antenna for ultra-wideband (UWB) application with band-notched characteristics is presented. Two modified coplanar waveguides (CPW) are used to feed the staircase-shaped radiating elements respectively, which generate orthogonal radiation patterns. One rectangle stub placed at 45 degrees axis between the two coplanar waveguides ensures the isolation above 15 dB. Two...
The influence of regional culture and values on the Chinese human resource market has been steadily increasing, but unconsciously. In recent years scholars have studied a variety of phenomena that imply a shift-away from classical explanations of talent flow and human resource patterns. This has led to the coining of some new terms and concepts, such as "Ant Tribe". This tendency towards...
This study focuses on the investigation of the relationship between tenure of top management teams (TMTs) and corporate performance. 73 Chinese listed real estate companies are selected as our samples, and hierarchical regression statistical methods are used to analyze the collected data. Then we conclude that: (a) TMTs' average tenure is negatively related to short-term firm performance. But it is...
