The decomposition processes and reactivity of C4F90CH2O• radical formed from C4F90CH3 (HFE-7100) have been studied by density function theory computational methods. All calculations were performed at B3LYP and mPW1PW91 levels of theory with the 6-311G(d,p) basis set. The calculated barrier heights were further improved... |
Channel estimation for an orthogonal frequency-division multiplexing (OFDM) broadband system over a dynamic sparse channel has become a challenging problem. Due to the special feature of dynamic sparse channels: path delays change over time, the channel sparsity changes dynamically. We propose a differential simultaneo... |

A summary of a critical review by a working group of the German commission on Air Pollution Prevention of VDI and DIN of the actual data on exposure and health effects (excluding cancer) of fine particulate air pollution is presented. |
EXPOSURE |
Typical ambient particle concentrations for PM10 (PM2.5) in Germany are in the range of 10-45 (10-30) microg/m3 as annual mean and 50-200 (40-150) microg/m3 as maximum daily mean. The ratio of PM2.5/PM10 generally amounts between 0.7 and 0.9. |
HEALTH EFFECTS |
During the past 10 years many new epidemiological and toxicological studies on health effects of particulate matter (PM) have been published. In summary, long-term exposure against PM for years or decades is associated with elevated total, cardiovascular, and infant mortality. With respect to morbidity, respiratory sym... |
CONCLUSION |
The working group concludes that a further reduction of the limit values proposed for 2005 will substantially reduce health risks due to particulate air pollution. Because of the strong correlation of PM10 with PM2.5 at most German sites there is no specific need for limit values of PM2.5 for Germany in addition to tho... |
in this research, the kinetics of carbothermic reduction of molybdenite in the presence of sodium carbonate was studied. For this purpose, mixed powder of molybdenite, graphite, and sodium carbonate with 1:4:2 mole ratio was investigated using simultaneous thermal analysis (STA) at the heating rates of 10, 15 and 20 0C... |
In natural scenes, multiple visual stimuli compete for selection; however, each saccade displaces the stimulus representations in retinotopicaly organized visual and oculomotor maps. In the present study, we used saccade curvature to investigate whether oculomotor competition across eye movements is represented in reti... |

Recently, received signal strength indicator (RSSI)-based range measurement technology is widely used in sensor network for its low-cost. But the radio signal transmission is influenced by the factors of channel atte... |
RNA produced from a number of genes on the mitochondrial (mt) DNA of Physarum polycephalum have nucleotides inserted at specific sites in their sequence. These insertions are spaced at approximately 25 nucleotide intervals and create open reading frames in mRNA and functional structure in tRNAs and rRNAs. Although most... |
In this study, we successfully developed gold nanoparticles capped with histidine (His-AuNPs) for Hg 2+ detection using trisodium citrate as the reducing agent. The optimum pH for the detection of Hg 2+ by His-AuNPs was 12. The addition of Hg 2+ to the His-AuNPs caused the color change from red to black-blue, which is ... |
The human population is infested with dermatological diseases. For example, at a global scale, 95% of people are infected with the Herpes Simplex Virus (HSV) and 90% of people contract the Human Papillomavirus (HPV) in their lifetime. Yet, while the healthcare law literature is visibly scaling, the research relating to... |

Patients with Peutz–Jeghers syndrome (PJS) are known to be at risk of gastric cancer (GC), and the STK11 gene is a susceptibility gene for PJS. However, as no cases of PJS with GC in which a STK11 germline mutation has been identified have ever been reported and other susceptibility genes have also been suggested to be... |
Mutualists and antagonists are known to respond to similar floral cues, and may thus cause opposing selection on floral traits. However, we lack a quantitative understanding of their independent and interactive effects. In a population of the orchid Gymnadenia conopsea, we manipulated the intensity of pollination and h... |
Abstract Natural disasters devastate economies as they impede capital accumulation. The resilience of labour markets is crucial for the poor who rely on labour to reduce risk. We evaluate how the 1998 ‘flood of the century’ affected wages in Bangladesh. We find short-term declines in agricultural and non-agricultural w... |

In the design of ligand-protected metal clusters, the choice of protecting ligands is a critical factor because they can profoundly affect the nuclearity, geometry, and electronic structures to afford a diverse range of cluster compounds. Here, we report the synthesis of two novel diarsine-protected Au13 clusters ([Au1... |
Of the approximately 11 million tonnes of annual solid concrete and demolition waste (C&D) in Canada, concrete accounts for about 52% by weight. However, most of this concrete is used as highway base or sent to landfills for disposal; only a very small portion of the concrete waste is reused in building construction. C... |
