A single-slope greenhouse (SSG) is the general name of a kind agricultural facility widely used in China. Microclimate studies for SSGs Weifang, Shandong Province, are relatively scarce. This paper mainly discusses test data nine including temperature, humidity, solar global radiation intensity, CO2 concentration, wind speed, and vapor pressure deficit (VPD) trend. Moreover, conservation qualit...

Taiwanese tone sandhi, although a phrase-level pattern, has been argued to be essentially lexicalized. We thus expected it to be phonetically categorical and insensitive to pragmatic context. To test these predictions, we had native speakers read aloud pairs of sentences identical except for morphemes expected to be neutralized by tone sandhi, both across and within prosodic positions. Speakers...

The calculation of slope (downhill gradient) for a point in a digital elevation model (DEM) is a common procedure in the hydrological, environmental and remote sensing sciences. The most commonly used slope calculation algorithms employed on DEM topography data make use of a three-by-three search window or kernel centered on the grid point (grid cell) in question in order to calculate the slope...

Abstract The present study investigates the maximum temperature and smoke back-layering length S in downhill direction from fire source a tilted tunnel under natural ventilation. Numerical simulations were conducted using FDS to flow behaviors for with nine slopes of 0, 1%, 2%, 3%, 4%, 5%, 6%, 7% 8%. It was found that, due stack effect, stagnated at distance direction. effects slope, ? , heat r...

Behavioral and EEG studies suggest spatial attention is allocated as a gradient in which processing benefits decrease away from an attended location. Yet the spatiotemporal dynamics of cortical processes that contribute to attentional gradients are unclear. We measured EEG while participants (n = 35) performed an auditory spatial attention task that required a button press to sounds at one targ...

Motivated by models of fracture mechanics, this paper is devoted to the analysis of a unilateral gradient flow of the Ambrosio-Tortorelli functional, where unilaterality comes from an irreversibility constraint on the fracture density. Solutions of such evolution are constructed by means of an implicit Euler scheme. An asymptotic analysis in the Mumford-Shah regime is then carried out. It shows...

The metabolic cost of the negotiation of obstacles, and the influence that this has on route selection, are important determinants of an animal's locomotor behaviour. We determined the gross metabolic cost of locomotion on slopes of different gradients, ranging from -90 to +90 deg, in leaf-cutter ants (Acromyrmex octospinosus) in a closed-circuit respirometry system. Ants were able to select th...

Open-cut coal mining in Queensland results in the formation of extensive saline overburden spoil-piles with steep slopes at the angle of repose (approximately 75% or 37o). These spoil-piles are generally found in multiple rows, several kilometers in length and heights of up to 50 or 60 m above the original landscape. They are highly dispersive and erodible. Legislation demands that these spoil ...

BACKGROUND AND PURPOSE This study sought to determine the degree of agreement between asymmetries of neuropsychological functioning and nine methods of quantifying asymmetries of regional cerebral blood flow. METHODS The regional cerebral blood flow methods combined three markers of cerebral blood flow asymmetry (percent hemispheric difference, maximum percent probe-pair asymmetry, and number...
