A variety of combinations of CdS, TiO2, and Pt in preparing the hybrid catalysts were studied for hydrogen production under visible light (l > 420 nm) irradiation. The preparation method sensitively influenced the activity of the ternary hybrid catalysts. The formation of the potential gradient at the interface between CdS and TiO2 is necessary in achieving the efficient charge separation and t...

Although the cytoplasm of spermatids is removed at the end of spermiogenesis, a tiny portion is usually retained in the sperm flagellum, which is termed the cytoplasmic droplet (CD) in mammals. CDs are believed to play a role in sperm volume adaptation. However, we have noticed that epididymal spermatozoa that display initial (flagellation in situ) and progressive motility mostly possess CDs, w...

OBJECTIVES To develop a valid and reliable instrument to assess caregiver burden in caregivers of children with cerebral palsy (CP). METHODS A self-administered, multidimensional instrument--Caregiver Difficulties Scale (CDS)--was developed using a combined qualitative-quantitative approach. Items for the preliminary draft were selected from existing caregiver assessment instruments by consen...

Fluorescent carbonaceous nanodots (CDs) have attracted much attention due to their unique properties. However, their application in noninvasive imaging of diseased tissues was restricted by the short excitation/emission wavelengths and the low diseased tissue accumulation efficiency. In this study, CDs were prepared from glucose and glutamic acid with a particle size of 4 nm. Obvious emission c...

Using 5-year credit default swap (CDS) contracts on 1,247 U.S. firms from 2003 2011, we show a 3-month formation and 1-month holding period CDS momentum strategy yields 52 bps per month. By incorporating past CDS return signals, we further show traditional stock momentum strategies avoid abrupt losses during the crisis period and improve their performance by net 104 bps per month. Both within C...

A green approach was developed from the preparation of fluorescent carbon dots (CDs) by using water chestnut as precursor. The preparation of CDs was performed by simple pyrolsis. The as-prepared CDs are uniform in size, and the quantum yield was 12.6% by using quinine sulfate as the reference. Significantly, not only the precursor of CDs and whole synthesis procedure was green, but also the CD...

OBJECTIVE To review the literature on clinical decision support (CDS) for genetically guided personalized medicine (GPM). MATERIALS AND METHODS MEDLINE and Embase were searched from 1990 to 2011. The manuscripts included were summarized, and notable themes and trends were identified. RESULTS Following a screening of 3416 articles, 38 primary research articles were identified. Focal areas of...

Close-spaced-sublimated (CSS) CdS films exhibit strong fundamental edge luminescence, high optical absorption, and a bandgap of ~2.41 eV. Structurally, these films show good crystallinity with thickness-dependent grain sizes that vary between 100-400 nm. In contrast, chemical-bath-deposited (CBD) CdS exhibits subband luminescence, lower absorption, and a thicknessdependent bandgap. These films ...

Three experiments evaluated the effects of condensed distillers solubles (CDS) on performance and metabolism characteristics in finishing diets. In Exp. 1, 250 crossbred steers (355 ± 18 kg of BW) were used in a randomized complete block design study and fed 0, 9, 18, 27, or 36% CDS to replace a portion of urea and a 1:1 ratio of dry-rolled corn (DRC) and high-moisture corn (HMC). Dietary fat i...
