| 1 | Grazing effects on herbage nutritive values depend on precipitation and growing season in Inner Mongolian grassland显示文摘Aims Grasslands are widely used for production of livestock,which depend on the nutritive value of herbage species.However,there are still large uncertainties as to how grazing,precipitation and growing season interactively affect herbage nutritive value.Methods Here,based on a grazing experiment with seven grazing intensities in an Inner Mongolian grassland since the year 2005,we analysed nutritive value of four dominant grass species from June to September in both a relatively wetter year(2008)and a drier year(2010).Herbage with high nutritive value is characterized by high concentration of crude protein,high concentration of cellulase digestible organic matter and low concentration of neutral detergent fibre.Important Findings We found that(i)grazing significantly increased the nutritive value of Leymus chinensis,Agropyron michnoi and Cleistogenes squarrosa but had minor effects on the nutritive value of Stipa grandis.(ii)For all species,nutritive values were greater in the wetter year than in the drier year and were greatest in the early growing season(June)and lowest at the end of the growing season(September).Inter-annual and inter-seasonal variations in nutritive value were much greater for L.chinensis and A.michnoi than for C.squarrosa and S.grandis,suggesting higher water use efficiency for the latter two species.(iii)Grazing significantly decreased the drought resistance of three species,but not of S.grandis.(iv)Grazing significantly increased inter-month variation in nutritive value for L.chinensis and A.michnoi but had relatively minor or no effects on that of C.squarrosa and S.grandis.Therefore,grazing effects on species nutritive values showed strong inter-annual and seasonal patterns,and species-specific responses might be related to species traits(i.e.water use efficiency,digestibility).Our results have important implications for ecosystem management of arid and semiarid grasslands under intense grazing and global climatic change. | Haiyan Ren Guodong Han Zhichun Lan Hongwei Wan Philipp Schönbach Martin Gierus Friedhelm Taube | 2016 | Journal of Plant Ecology2016,9,6: | 14 |
| 2 | 28例转移性肝癌腹腔镜肝切除术显示文摘目的总结转移性肝癌的腹腔镜肝切除术经验。方法对1999—2006年度布里斯班医院所实施的转移性肝癌腹腔镜肝切除术病人进行回顾性研究。结果经病理证实的28例转移性肝癌病人进行了腹腔镜肝切除,13例进行左肝外侧叶切除,9例进行了右半肝切除。其余6例行肝段或不规则切除。追踪随访12例由直结肠转移的转移性肝癌病人2年存活率和无瘤生存率分别为75%和67%。结论在严格选择过的恶性肿瘤病人中行腹腔镜肝切除术是安全可行的。对病人要有适当的分期.术者需具丰富的开腹肝切除术经验和腹腔镜操作技能。 | 吴志明 Nick O'Rourke Lan Shaw Les Nathanson Lan Martin George Fielding | 2009 | 中华肝胆外科杂志2009,15,12: | 8 |

| 4 | Estimating the size and travel distance of Klapperhorn Mountain debris flows for risk analysis along railway, Canada显示文摘Debris flows occurring on Klapperhorn Mountain in the Yellowhead Pass in the Canadian Rocky Mountains pose a significant hazard to railway operations at the base of the mountain. The size (volume) and travel distance of these debris flows play an important role in assessing the risk to the railway. GIS analysis, airphoto interpretation together with field work were undertaken on two debris flows located at track mileage 54.0 and 54.3. Characteristics of these two debris flow events were analyzed, including debris flow path morphology and event behavior. Their sizes and travel distances were estimated using an empirical-statistical model (UBCDFLOW) under different initiation conditions. Their potential impact on the railway bridge was evaluated using a bridge blockage ratio. | Hengxing LAN C. Derek MARTIN C. H. ZHOU | 2008 | International Journal of Sediment Research2008,23,3: | 3 |
| 5 | Laboratory evaluation of the GreenSeeker^(TM) handheld optical sensor to variations in orientation and height above canopy显示文摘Handheld optical sensors recently have been introduced to the agricultural market.These handheld sensors are able to provide operators with Normalized Difference Vegetative Index(NDVI)data when cloud cover prevents acquisition of satellite or aerial images.This research addressed the sensitivity of the GreenSeeker handheld optical sensor to changes in orientation and height above a ryegrass canopy.Planter boxes were oriented both parallel and perpendicular to the light beam from the sensor head and heights of 30.5 cm(12”),61.0 cm(24”),91.5 cm(36”),122 cm(48”)and 152 cm(60”)were tested.Results indicated that the sensor was highly sensitive(P<0.0001)to both height above canopy and orientation of the sensor relative to the target.Operators should follow manufacturer’s recommendations on operating height range of 81-122 cm and orient the sensor head in-line with the target to obtain maximum signal response. | Daniel E Martin Juan D Lopez Jr Yubin Lan | 2012 | International Journal of Agricultural and Biological Engineering2012,5,1: | 2 |
