In this paper, we consider singular and degenerate parabolic equations$$u_t =(x^alpha u_x)_x +u^m (x_0,t)v^{n} (x_0,t),quadv_t =(x^beta v_x)_x +u^q (x_0,t)v^{p} (x_0,t),$$ in $(0,a)times (0,T)$, subject to nullDirichlet boundary conditions, where $m,n, p,qge 0$, $alpha, betain [0,2)$ and $x_0in (0,a)$. The optimal classification of non-simultaneous and simultaneous blow-up solutions is determin...

The road environment can affect driver speed choice through influencing both the driver’s perception of their current speed, and the speed that they think is appropriate for the road. These influences and their effects on speed can therefore affect crash rates. This report reviews the influence of various factors within the road environment, including the geometry of the road, the roadside envi...

COVINGTON, KY. – Providers continue to rely on blood cultures to detect serious bacterial infections in children with bronchiolitis, even though urinary tract infections are the most common culprit, a chart review showed. “Even though there is outstanding evidence in the literature that cultures are unnecessary in the vast majority of infants with clinical bronchiolitis, this practice is common...

This paper investigates how freight rates paid by shippers are affected the characteristics of urban areas origin and destination. It is based on a commodity flow survey between 45 Japanese prefectures from 2000 to 2010. Through an analysis rates, authors seek identify advantages disadvantages faced firms depending spatial arrangement their flows. The results show that shipping cargo small larg...

The assessment of harsh working conditions requires a correct evaluation of the metabolic rate. This paper revises the basis described in the ISO 8996 standard for the evaluation of the metabolic rate at a work station from the recording of the heart rate of a worker during a representative period of time. From a review of the literature, formulas different from those given in the standard are ...

The effect of temperature on the evolution of metabolism has been the subject of debate for a century; however, no consistent patterns have emerged from comparisons of metabolic rate within and among species living at different temperatures. We used experimental evolution to determine how metabolism evolves in populations of Drosophila melanogaster exposed to one of three selective treatments: ...
