Research ArticleOpen accessAll words, across the recordSimplified Analysis of the Lining Behavior During Earthquakes in Deep Rock TunnelsPierpaolo OresteThe sizing of the lining of a tunnel requires to consider not only the static loads transmitted from the surrounding rock, but also the effects of earthquakes on the stresses and strains of the lining. The detailed evaluation of the interaction earthquake-lining using numerical methods typically requires very long calculation time and can be limited to the verification of the … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 4 May 2015 · 6,901 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Importance of Maintaining a Proper Database on Forest Restoration Program for Orangutans in BorneoRaymond Alfred, Koh Pei Hue, Lee Shan Khee, Rayner AlfredProblem statement: The lowland forest of Sabah is the most important habitat for orangutans and pygmy elephants. This is shown in the WWF-Malaysia’s elephant tracking programme in which satellite-based Global Position System (GPS) collar devices are used to monitor their movement and the range of their habitats, as well as an aerial survey on orangutan’s nest is performed to determine … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,910 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordVegetation Assessment of Peat Swamp Forest Using Remote SensingSeca Gandaseca, John Sabang, Osumanu Haruna Ahmed, Nik Muhamad Ab.

Research ArticleOpen accessAll words, across the recordUse of Cross-linking to Assess Subunit Interaction of Recombinant Human Coproporphyrinogen OxidaseJason R. Stephenson, Nancy E. Thomas, Jon A. Friesen, Marjorie A. JonesTo provide further evidence for a dimeric form of coproporphyrinogen oxidase reported using the conventional hydrodynamic methods, bifunctional cross-linkers were incubated with purified, recombinant human coproporphyrinogen oxidase to determine subunit interaction in solution. The use of cross-linkers provides an effective way to demonstrate subunit association and allows for assessment of activity upon covalent cross-linking. Following incubation with selected cross-linkers, enzyme … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,594 accessesView PDF Cite
