In this paper, Forchheimer equation is used as the constitutive equation for flow through rockfill, and the non-linear two-dimensional governing equation with free surface is solved by a new finite element method in a fixed grid. The model is verified by applying it to different flow conditions. The first scenario, which is assumed to be one-dimensional with analytical solution available for it...

BACKGROUND Leptospira can be found in soil. However, it is unclear whether occupational exposure to soil may represent a risk for Leptospira infection in humans. Therefore, we sought to determine the association of Leptospira IgG seroprevalence with the occupation of gardener, and to determine the epidemiological characteristics of gardeners associated with Leptospira exposure. METHODS We per...

This study sheds light on a new generation of Swedish food producers, market gardeners, who are attracting attention in terms system sustainability, prompted by increasing consumer awareness about the value healthy and locally produced food. Market gardening is part global agroecological movement opposed to industrialized agriculture its negative impacts environment rural communities. These pro...

In spite of the fact that pampering with proper care and management are better than ever before, woody plants are accumulating no more fat today than they did centuries ago. If anything, the rise in the number of certified arborists, master gardeners, and professional landscape managers applying their skills along with enforcement of clean air standards have resulted in healthier plants in our ...
