Soil and water conservation is essential for sustaining food production and for preserving the environment in arid and semi arid lands （ASALs） where conditions for agriculture and other land use systems are often harsh and unpredictable. The ASALs of Algeria are an important source of a variety of non wood forest products like Stipa tenacissima L. plant （esparto grass）. This research was conducted to determine the effects of different low concentration （〈 I%） polyacrylaJnide, Stipa tenacissima L. fiber （esparto grass fibers） and its mixtures with the polymer at water retention in arid and semi arid soil. All samples are characterized by infrared spectroscopy, X-ray Diffractometry, thermal analysis TG DSC and scanning electron micrographs （SEM）. The results showed that polymer blend in soil could improve better soil physical proprieties decreased evaporation and increase water retention in arid soils compared with application of any other blend at the same concentration. The use of Polyacrylamide-Cellulose blend appears to promise for reducing the labor cost of irrigation at arid and semi-arid soils, and offers safe and environmentally friendly inexpensive materials. The importance of Polyacrylamide-Cellulose blends to alleviate poor physical properties and retain water in these arid regions to sustain plant growth.

Study on plant fiber/plastic composites as the substrate of floorboard

引用

Journal of Forestry Research 2005年第3期16卷 245-246页

作者： YANG Wen-bin LI Jian LIU Yi-xing Fujian Agricuhure and Forestry University Fuzhou 350001 P. R. China Key laboratory of Bio-based Material Science and Technology （Northeast Forestry University

Three kinds of composites （fiber/Polypropylene, fiber/Polyethelene, and fiber/Polystyrene） were made by using hot pressing process for substrate of floorboard and the properties of each kind of composites were tested. MORs of PP/wood fiber, PS/fiber, and PE/fiber composites with coupling agent added were raised by 18.4%, 37.1%, and 42%. respectively, compared to those without coupling agent. Among the three kinds of fiber/plastic composites, fiber/PP composite has best mechanical properties, and it can meet quality standard of eligible grade product and come up to the excellent grade products of China when the coupling agent is added. The performance of composite made of PE/fiber or PS/fiber can exceed qualified product grade only with coupling agent added.

Primates access energy from plant fiber via bacterial fermentation in either a modified forestomach(‘foregut’),a caecocolic(‘hindgut’)chamber of the large intestine,or *** digestive retention times allow for more complete fermentation;as such,primates that consume an herbivorous diet high in fiber are expected to have both relatively and absolutely longer retention times than those mammals that rely on more readily digestible plant foods,such as *** used particulate markers to measure the digestive retention times of captive Allen’s swamp monkeys[Allenopithecus nigroviridis(Pocock,1907)](n=3)and L’Hoest’s monkey(Cercopithecus lhoesti ***,1899)(n=2).Results indicate mean retention times of 23.2-29.4 h and 23.2-24.0 h for *** and ***,*** from this study,in combination with previously published data on digestive retention times in other primate species,indicate that cercopithecines differ from other primate taxa by having lengthier retention times that can be predicted by body mass *** data are consistent with the hypothesis that relatively lengthy retention times are a primitive trait for Cercopithecinae.

APPLICATION OF THE COLLAGENOUS fiber FROM THE SOLID WASTES OF LEATHER FOR PAPERMAKING

引用

天津科技大学学报 2004年第S1期 314-317页

作者： Zhijie Wang1, Jian Wang1, Zhang Chuanbo2, Hou Xiaodong2 1 School of Papermaking Engineering, Shaanxi university of Science & technology, Xianyang, 712081, China 2 School of leather Engineering, Shaanxi University of Science & Technology, Xianyang, 712081, China

The capability of pulping for the solid waste of leather was investigated. The properties of paper that made up of collagenous fiber and plant fiber were also analyzed. The result showed that by proper treatment, solid waste of leather could be made into collagen fiber for papermaking. The physical strength of paper can be enhanced by appending collagenous fiber in a proper propriety.
