Fine-grained tungsten carbide copper (WC-Cu) cemented carbide was sintered via spark plasma sintering at 1773K using a fine WC powder with a mean particle size of 0.11 mm. The mechanical properties were compared with tungsten carbide cobalt (WC-Co) cemented carbide and a binderless WC-sintered material. The Vickers hardness and fracture toughness obtained by the indentation fracture method for ...

In the Neurospora circadian negative feedback loop, white collar 1 (WC-1) and WC-2 form the WC complex that activates frequency (frq) transcription. Here we show that Not1 is a WC-interacting protein and is important for maintaining WC levels. The not1 transcript displays a circadian oscillation with a similar phase as frq. Down-regulation of not1 leads to low levels of WC-1 and WC-2 and a dela...

Denitrifying bioreactors can be effective for removing nitrate from agricultural tile drainage; however, questions about cold springtime performance persist. The objective of this study was to improve the nitrate removal rate (NRR) of denitrifying bioreactors at warm and cold temperatures using agriculturally derived media rather than wood chips (WC). Corn ( L.) cobs (CC), corn stover (CS), bar...

This study aimed to examine differences in CVD risk factors across four crosstabulated groups according to health-related physical fitness index (PFI, composite index of standing long jump, 50-m test, and 800or 1000-m run/walk) and waist circumference (WC) in Guangzhou youth. Participants comprised 588 males and 579 females aged 11–18 years from Guangzhou, China. They were cross-tabulated into ...

We present the properties of the 12CO(1-0) and (3-2) line emission from the nuclei of 60 IR luminous SLUGS galaxies. This subsample is flux limited at S60μm ≥ 5.24 Jy with FIR luminosities mostly at LFIR > 10 10 L⊙. The emission line strengths of 12CO(1-0) and (3-2) transitions were compared at a common resolution of ∼ 15, and the line ratios r31 vary from 0.22 to 1.72 with a mean value of 0.66...

Context. BP Psc is a puzzling late-type, emission-line field star with large infrared excess. The star is encircled and enshrouded by a nearly edge-on, dusty circumstellar disk, and displays an extensive jet system similar to those associated with pre-main sequence (pre-MS) stars. However, the photospheric absorption features of the star itself appear more consistent with post-main sequence sta...

We present 12CO,13CO and C18O J=1→0, and 12CO and 13CO 2→1 and 3→2 observations of the Rosette Molecular Complex (RMC), obtained with the KOSMA 3m and IRAM 30m telescopes. We introduce a method for correcting error beam pick-up of single-dish telescopes in spectral line radio maps by using observations of a smaller telescope and apply it to correct the IRAM 30m data presented in this paper by t...

Using the IRAM interferometer, we have observed the nearby starburst galaxy M 82 with a 4. ′′2 resolution (' 70 pc) in the 1→0 line of 13CO and in the λ 2.6-mm continuum. The spatial distribution of the 13CO line shows the same gross features as the 12CO(1→0) map of Shen & Lo (1995), namely two lobes and a compact central source, though with different relative intensities. The lobes are more co...

BACKGROUND Current criterion of waist circumference (WC) for abdominal obesity is not enough to demonstrate characteristics of obese and non-obese populations defined by BMI. The aim of this study was to redefine the cutoff values of WC according to general obesity (BMI ≥ 25 kg/m(2)). METHODS The receiver operating characteristic curve analysis was performed to determine cutoff values of WC f...

BACKGROUND In adults, overweight is associated with reduced lung function, in children evidence on this association is conflicting. We examined the association of body mass index (BMI) and waist circumference (WC) at age 12, and of persistently (at ages 8 and 12 years) high BMI and large WC, with forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) at age 12. METHODS He...
