The combined effect of shear and buoyancy on dispersion behind a fence is examined. Stable turbulent boundary layers up to Rigrad 1⁄4 0.2 are generated by a recycle method. The fence affects concentrations up to at least 100 obstacle heights downstream. The decay of maximum velocity and temperature deficit is independent of stability. The decay in maximum concentration excess decreases appreciably

respect and reverence for water and trees are institutionalised in many ancient civilisations due to socio-cultural traditions, values and beliefs. in iranian societies, respect for trees and water, separately and in composite form as gardens, is a well-known cultural value both before and after islam. therefore, the first part of this paper explains the value and importance of plants and garde...

What are the effects of snow fence variables on wind patterns, and geometry and volume of snow collected in drifts? This question arose from a need to capture winter’s blowing snow to improve water supply during a drought and to protect critical areas from blowing snow. Last year, during the first phase of this project, various powders were tested to find which would closely replicate snow in a...

Urban beekeeping is becoming more popular in the UK. One of the challenges faced by urban beekeepers is finding a suitable apiary location. Honey bees are often perceived as a nuisance, mainly due to their stinging behaviour. Here, we experimentally test the assumption that barriers around an apiary such as walls or fences, force the bees to fly above human height, thereby reducing collisions w...

There will also be all-weather Bio-Domes designed by Jerry Tate (architect of the CORE educational facilities at the Eden Project). Feeling peckish? Enjoy a feast on the Slow Food Moving Restaurant, where tables and chairs snake up through the ‘hanging gardens’ atrium, into rooms created by food-artists. Discover innovative, fresh, locally produced food, designed to stimulate all the senses, de...

limited by the timing of new tiller development. Development of new tillers in smooth bromegrass is largely Smooth bromegrass (Bromus inermis Leyss) is poorly adapted to determinant, with synchronized elevation and elongamanagement-intensive rotational grazing because of slow and limited tion of new apical meristems above the soil surface regrowth potential. In an effort to discover germplasm w...

Cover Art Caption: Odor emission from swine facilities is a major issue for the pork industry. Here, air samples are taken to determine the impact of reducing dietary crude protein concentration through the use of crystalline amino acids on odor emission into building air. The effects of type of housing (stalls versus pens) and method of heat detection (fence-line boar exposure conducted in-pla...
