results the mean age and work experience of workers were 31.39 ± 5.6 and 4.35 ± 2.5 years, respectively. among the exposed-to-noise personnel, 7.35% used hpds constantly; 75% used hpds for only short periods of time (less than four hours) and 17.65% did not make use of them at all. regarding the sound intensity and the level of noise reduction of hpds, among the 112 workers who used such device...

Gold nanoparticle assemblies significantly enhance optical fields and have been applied for nano-optical devices, biosensing, chemical reactions. The properties of the assembly are, however, less controllable once are fabricated on a solid substrate. An prepared at water-organic solvent interface overcomes this restriction provides flexible photochemical reaction fields. Additionally, physical ...

In this work we consider the problem of continuously monitoring a collection of data sets produced by sensors placed on moving or static targets. We propose a modification of the static sensor field model (SSSF) [2] to model computation in a dynamic network of tiny artifacts. We consider mobility coming from both the communication devices and the data. The mobility of devices is simulated by a ...

Microfluidic systems with splitting structures are excellent for increasing emulsion production. However, traditional two-dimensional (2D) lithographic systems require complex modification of the microchannel surfaces and achieve only 2D splitting of the droplets. Herein, we present new glass capillary microfluidic devices that perform three-dimensional (3D) splitting of droplets. These devices...

Due to their potentials in light-weight, flexible, and semitransparent devices, organic photovoltaics are of great significance the field renewable energy. However, narrow intrinsic absorption spectrum materials hinders full utilization solar To fabricate a highly efficient opaque cell, it is greatly necessary modify optical properties device improve light absorption. In addition, growing inter...

Due to the explosion of smart devices, data traffic over cellular networks has seen an exponential rise in recent years. This increase in mobile data traffic has caused an immediate need for offloading traffic from operators. Device-to-Device(D2D) communication is a promising solution to boost the capacity of cellular networks and alleviate the heavy burden on backhaul links. However, dir...

Biocompatible polymer brushes were successfully synthesized on diamond-like carbon (DLC) films via surface-initiated atom transfer radical polymerization (SI-ATRP) of 2-mtharyloyloxyethyl phosphorylcholine (MPC). The DLC film with a water contact angle (WCA) approximately 71.9° was modified into highly hydrophilic surface WCA 15.0° after MPC brush modification. Protein adsorption tests using qu...

This paper presents a simple method to change the hydrophilic nature of the glass surface in a poly(dimethylsiloxane) (PDMS)-glass hybrid microfluidic device to hydrophobic by an extra-heating step during the fabrication process. Glass substrates bonded to a native or oxygen plasma-treated PDMS chip having microchambers (12.5 mm diameter, 110 µm height) were heated at 200°C for 3 h, and then t...
