  • Thermo-mechanical processing of sugar beet pulp. I. Twin-screw extrusion process
    Carbohydrate Polymers, 2006
    Co-Authors: Antoine Rouilly, Jeremy Jorda, Luc Rigal
    Abstract:

    Abstract Sugar beet pulp (SBP) is the raffinate of sugar extraction. Composed of empty vegetal cells, three quarters of it consist of polysaccharides. As it is cheap and produced in great quantities SBP is a potential raw material for industrial applications other than Cattle Feeding. Twin-screw extrusion modified its structure and destructuring level depended on the specific mechanical energy provided (SME). By gradually increasing this energy, the rate of soluble matter increased, cell structure was progressively destroyed and SBP rheological behaviour was modified. For an SME of 745 W h kg −1 , SBP examined through a scanning electron microscope showed a structure similar to that of a composite formed by a continued matrix consisting mainly of pectin and hemicelluloses filled with cellulose microfibres. Plasticized SBP was then formed by injection-molding. Thus treated, SBP becomes a cheap alternative to the use of thermoplastic starch for the production of biodegradable materials.

  • forest on the edge seasonal cloud forest in oman creates its own ecological niche
    Geophysical Research Letters, 2006
    Co-Authors: Anke Hildebrandt, Elfatih A. B. Eltahir
    Abstract:

    [1] Cloud forests usually grow in the moist tropics where water is not a limiting factor to plant growth. Here, for the first time, we describe the hydrology of a water limited seasonal cloud forest in the Dhofar mountains of Oman. This ecosystem is under significant stress from camels Feeding on tree canopies. The Dhofar forests are the remnants of a moist vegetation belt, which once spread across the Arabian Peninsula. According to our investigation the process of cloud immersion during the summer season creates within this desert a niche for moist woodland vegetation. Woodland vegetation survives in this ecosystem, sustained through enhanced capture of cloud water by their canopies (horizontal precipitation). Degraded land lacks this additional water source, which inhibits re-establishment of trees. Our modeling results suggest that Cattle Feeding may lead to irreversible destruction of one of the most diverse ecosystems in Arabia.

  • Ecohydrology of a seasonal cloud forest in Dhofar
    2006
    Co-Authors: Elfatih A. B. Eltahir
    Abstract:

    Cloud forests usually grow in the moist tropics where water is not a limiting factor to plant growth. Here, for the first time, we describe the hydrology of a water limited deciduous cloud forest in the Dhofar mountains of Oman. This ecosystem is under significant stress due to land degradation from camel Feeding on tree canopies. Our experimental field observations and numerical experimentation suggest that cloud immersion contributes to creating an ecological niche for a drought deciduous forest biome within an otherwise desert environment. Cattle Feeding may lead to irreversible destruction of one of the most diverse Arabian ecosystems.
