Among the environmental problems that could affect agriculture, one of most critical is ponding. This may be defined as water storage on surface in concavities and depressions due to soil saturation. Stagnant can seriously crops management agricultural landscapes. It mainly caused by prolonged rainfall events, type, or wrong mechanization practices, which cause compaction. To better understand ...

let g be a graph with p vertices and q edges and a = {0, 1, 2, . . . , [q/2]}. a vertex labeling f : v (g) → a induces an edge labeling f∗ defined by f∗(uv) = f(u) + f(v) for all edges uv. for a ∈ a, let vf (a) be the number of vertices v with f(v) = a. a graph g is said to be vertex equitable if there exists a vertex labeling f such that for all a and b in a, |vf (a) − vf (b)| ≤ 1 and the in...

The novella Coraline follows a young girl as she rescues her parents from an alternate reality. In his short story, author Neil Gaiman covers scarcely one week of Coraline’s life. Still, the descriptions of Coraline’s experiences and thoughts can engage Carl Jung’s psychological theories of personality structure and individuation. In particular, I will analyze how Coraline’s character illustrat...

Provisioners capture items both for delivery and for self-feeding. In doing so, they may travel directly to and from a single location, visit several patches on each excursion from a delivery point, or alternate excursions to different destinations. Prey suitable for self-feeding versus delivery have differing attributes, which means that they are often best sought in different places. Visiting...

Accurate inversion of soil hydraulic parameters based on the van Genuchten–Mualem model has received much attention in science research. Herein, a hybrid algorithm method using particle swarm optimization and vector-evaluated genetic was used to invert θs, α, n, Ks, with objective functions infiltration rate, cumulative infiltration, water content. Then, numerical experiments were conducted fou...

Introduction: Athabasca Vallis (Fig. 1) is the youngest known outflow channel on Mars, dated by crater counting at 2-8 Ma [1,2]. In-channel geomor-phic features indicative of flooding include streamlined forms, longitudinal lineations, and transverse dunes [1,2]. The streamlined forms have been hypothesized to be primarily depositional, i.e. composed of sediment deposited out of the floodwater ...
