The dwindling capture fisheries has triggered an increase in Kenya's annual fish demand deficit, currently estimated at 553,000 MT. With the adoption of sustainable policies, aquaculture can bridge and surpass this deficit. farming environment is however characterized by its highly fragmented production farms, which limit dynamism technical change needed to commercialize aquaculture. global tre...

Scheduling problems for general cases are characterized as NP hard, and the computation time required to obtain the optimal schedule will grow exponentially with the problem size. The scheduling problems that consider the limited or shared resources, alterable constraints or environmental changes become very complex in both formulation and solution. Since the solution for these problems has gre...

Collapsing gullies are among the most severe soil erosion problems in the tropical and subtropical areas of southern China. However, few studies have examined the relationship of soil particle size distribution (PSD) changes with land-use patterns in the alluvial fans of collapsing gullies. Recently, the fractal method has been applied to estimate soil structure and has proven to be an effectiv...
