This study explored the use of phraseological frames (p-frames), a type of lexical bundle, by simultaneous interpreters as a strategy for managing cognitive loads. Specifically, using a comparable corpus of United Nations Security Council conferences, the study employed kfNgram to automatically identify the p-frames, and investigated their variations, regarding frequency, fixedness, structures, and functions among L1, L1-L2, and L2-L1 texts, which differ in cognitive loads due to task complexity and directionality of interpreting. The findings indicated that interpreters used more p-frames as cognitive loads increased; No significant difference was identified in fixedness as all texts tended to employ heavily formulaic and relatively fixed p-frames.

Current treatment strategies for CHB are not satisfactory as they induce a low rate of hepatitis B surface antigen (HBsAg) loss. Extracts were prepared from lettuce hydroponically cultivated in solutions containing glycine or nitrate as nitrogen sources.

Bruising is one of the major defects occurring on apple surface inevitably during postharvest handling and processing stage. To detect slight bruises on apples fast and efficiently, a novel bruises detection algorithm based on hyperspectral imaging and minimum noise fraction transform is proposed. First, the hyperspectral images in the visible and near-infrared (400 approximately 1 000 nm) ranges are acquired, and MNF transform based on full ranges could obtain better detection performance compared to PCA transform; Second, five wavebands (560, 660, 720, 820 and 960 nm) are selected as the effective wavebands based on the coefficient curve of I-RELIEF method conducted on spectra extracted from intact and bruise surface; Third, the bruises detection algorithm is developed based on the effective wavebands and MNF transform method.

In the crystal structure of the title compound, C(18)H(23)NO(2), there are only van der Waals inter-actions present. The cyclo-hexyl ring has a chair conformation. The longer axes of the displacement parameters of the non-H atoms forming the ethyl-methyl-carboxyl-ate skeleton are perpendicular to the plane through the non-H atoms of this skeleton.

Here, we characterize an inward Shaker K(+) channel, MIRK (melon inward rectifying K(+) channel), cloned in a salt-tolerant melon (Cucumis melo) cultivar, and show that this channel displays an unusual sensitivity to Na(+) . • MIRK expression localization was analyzed by reverse-transcription PCR (RT-PCR).

An incubation test was conducted to study the effects of different temperature (1 degrees C, 15 degrees C, and 25 degrees C) on the mineralization and adsorption of exogenous amino acid and peptide in the soils of horticultural production systems, including organic farming system (OS), transitional farming system (TS), and conventional farming system (CS). With the increase of incubation temperature, the mineralization of exogenous amino acids and peptides in test soils quickened. The mean half-life (D50) of Glu at 1 degrees C, 15 degrees C, and 25 degrees C was 13.

In addition, two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) were used to identify the proteins involved in the fenvalerate reaction process. Finally, the cDNA of P450 fragments was cloned and real-time RT-PCR was performed.
