Medicago sativa (lucerne) is a widely used perennial fodder crop and ranked amongst the highly nutritive fodders globally. This study assessed the nutritive value (i.e. CP % and TDN %) of four lucerne cultivars under two soil types at Bathurst Research Station. A random grid (quadrant) sampling method was used for sampling and samples were submitted to the laboratory for analysis to determine forage quality. Data collection was carried out by separating harvested biomass for each cultivar using clean packs, weighed and dried at 70˚C for 48 hours then crude protein (CP %) and Total Digestible Nutrients (TDN %) were determined. The results of the study showed that soil type (site) had a significant (P g CP content. Soil type also significantly affected (P gestible nutrient (TDN %) content of different lucerne cultivars. In S1, C4 (WL 525) had the highest (P generally produced highly nutritive lucerne in S2 while they produced less nutritive lucerne in relation to both CP and TDN content in S1.

万豪国际酒店集团新的Edition酒店就坐落在伦敦市中心的伯纳斯街上，酒店内的BernersTavern餐厅，墙上挂着近300幅照片。每张照片都品味不俗，装裱在洛可可风格的镀金相框里，密密麻麻地挂在酒吧灰褐色的墙上；照片主题有风景、动物、水果、充满艺术气息的乡间别墅；照片有大有小；有黑白的，也有彩色的。这些照片里，很少有任何一张值得再看第二眼，但它们一起排在豪华布艺长凳的上方，效果却是非常震撼。“这是一种发自内心的东西。”伊恩·施拉格（IanSchrager）说。去年9月酒店开业前，他亲自调整每幅照片，确定它们的位置，还亲自登上梯子调整灯光。“室内设计讲究的是整体效果，而不是关于某一个细节。”

In the present study, the Volterra series theory is adopted to theoretically investigate the force transmissibility of multiple degrees of freedom （MDOF） structures, in which an isolator with nonlinear anti-symmetric viscous damping is assembled. The results reveal that the anti-symmetric nonlinear viscous damping can significantly reduce the force trans- missibility over all resonance regions for MDOF structures with little effect on the transmissibility over non-resonant and isolation regions. The results indicate that the vibration isolators with an anti-symmetric damping characteristic have great potential to solve the dilemma occurring in the design of linear viscously damped vibration isolators where an increase of the damping level reduces the force transmissibility over resonant frequencies but increases the transmissibility over non-resonant frequency regions. This work is an extension of a previous study in which MDOF structures installed on the mount through an isolator with cubic nonlinear damping are considered. The theoretical analysis results are also verified by simulation studies.
