THIS STUDY WAS INITIATED TO EXPLORE THE EMISSION CHARACTERISTICS OF REDUCED SULFUR COMPOUNDS (RSCS: hydrogen sulfide, methyl mercaptan, dimethyl sulfide, dimethyl disulfide), ammonia and trimethylamine from a Wastewater Treatment Plant (WWTP) located at Sun-Cheon, Chonlanam-Do in South Korea. The study also evaluates flux profiles of the six selected odorous compounds and their flux rates (μg/m...

Adult stem cells (ASC) have been found in many tissues and are of great therapeutic potential due to their capability of differentiation. However, ASC comprise only a small fraction of the tissues. In order to use ASC for therapeutic purposes, it is important to obtain relatively pure stem cells in large quantities. Current methods for stem cell purification are mainly based on marker-dependent...

The nucleolus is the site of ribosome biosynthesis, but is now known to have other functions as well. In the present study we have investigated how the distribution of signal recognition particle (SRP) RNA within the nucleolus relates to the known sites of ribosomal RNA synthesis, processing, and nascent ribosome assembly (i.e., the fibrillar centers, the dense fibrillar component (DFC), and th...

Background: Subjective cognitive decline and amnestic mild impairment (aMCI) were widely thought to be preclinical AD spectrum disorders, characterized by aberrant functional connectivity (FC) within the triple networks of default mode network (DMN), salience (SN), executive control (ECN). Dynamic FC (DFC) analysis can capture temporal fluctuations in brain during scan, which static cannot. The...

Permanent magnet linear synchronous motor (PMLSM), which has the advantages of simple structure, small volume, high force, is a research focus and difficulties because of the thrust ripple and control problems for PMLSM. In this paper, in order to reduce thrust ripple and improve system control performance, the space voltage vector pulse width modulation technology (SVPWM) was introduced into t...

In order to achieve a longer battery life suppression of energy consumption is vital. A demand for design methods for less energy consumption is increasing. The subthreshold scaling can reduce energy per cycle significantly by the scaling of supply voltage (VDD) below threshold voltage (Vth). Threshold voltage of CMOS technology represents the value of the gate-source voltage when the current i...
