OBJECTIVES The rapid increase in drug expenditure has become a major source of public criticism in China. In 2009, the National Essential Medicine System (NEMS) was launched in China to control drug prices and improve access to medicines. This study investigated whether and to what extent the prices of essential medicines were reduced after the introduction of NEMS. METHODS Data were obtained...

In the last decade we have witnessed exciting technological advances in the fabrication and control of microelectromechanical and nanoelectromechanical systems (MEMS&NEMS) [16, 19, 26, 54, 55]. Such systems are being developed for a host of nanotechnological applications, such as highly sensitive mass [25, 34, 67], spin [56], and charge detectors [17, 18], as well as for basic research in the m...

Because of exceptional mechanical, chemical, and tribological properties, diamond has a great potential to be used as a material for the development of high-performance MEMS and NEMS such as resonators and switches compatible with harsh environments, which involve mechanical motion and intermittent contact. Integration of such MEMS/NEMS devices with complementary metal oxide semiconductor (CMOS...

Our work in carbon-microelectromechanical systems (C-MEMS) suggests that C-MEMS might provide a very interesting material and microfabrication solution to the battery miniaturization problem, active DNA arrays and a wide variety of chemical and biological sensors. We established that it is possible to use C-MEMS to create very high aspect ratio carbon structures (e.g. posts with an aspect ratio...

Nanolithography techniques providing a good scalability and feature size controllability are of great importance for the fabrication integrated circuits (IC), MEMS/NEMS, optical devices, nanophotonics, etc. Herein, cost-effective, easy...

This work proposes a methodology suitable for analysing the sound power levels (Lw), and carbon dioxide (CO2) nitrogen oxides (NOx) emissions along travel, consequentially assessing related critical hotspots. The estimation of noise pollutant from six vehicles driven three different routes (one National Road two highways) was conducted, in combined way, through seven Noise Emissions Models (NEM...
