The modified Reynolds.equation for ultra-thin gas.films.between magnetic head; dis. as.embly is.difficult to s.lve with conventional numerical methods. s.nce the bearing number is.very large; there exis. boundary layers.where pres.ure changes.rapidly. An iterative finite difference algorithm is.introduced to s.lve the nonlinear modified Reynolds.equation, with s.ecial treatment for the abrupt change in the thicknes. of the gas.film. The numerical res.lts.for two types.of magnetic heads.demons.rate that the s.heme is.effective.

Two plant s.ecies.Medicago truncatula (legume) and Avena s.tiva (non-legume),were grown in low-or high-N s.ils.under two CO2 concentrations.to tes. the hypothes.s.whether C allocation within plant-s.il s.s.em is.interactively or additively controlled by s.il N and atmos.heric CO2 is.dependent upon plant s.ecies. The res.lts.s.owed the interaction between plant s.ecies.and s.il N had a s.gnificant impact on microbial activity and plant growth. The interaction between CO2 and s.il N had a s.gnificant impact on s.il s.luble C and s.il microbial biomas. C under Madicago but not under Avena. Although both CO2 and s.il N affected plant growth s.gnificantly,there was.no interaction between CO2 and s.il N on plant growth. In other words.the effects.of CO2 and s.il N on plant growth were additive. We cons.dered that the interaction between N2 fixation trait of legume plant and elevated CO2 might have obs.ured the interaction between s.il N and elevated CO2 on the growth of legume plant. In low-N s.il,the s.oot-to-root ratio of Avena dropped from 2.63±0.20 in the early growth s.age to 1.47±0.03 in the late growth s.age,indicating that Avena plant allocated more energy to roots.to optimize nutrient uptake (i.e. N) when s.il N was.limiting. In high-N s.il,the s.oot-to-root ratio of Medicago increas.d s.gnificantly over time (from 2.45±0.30 to 5.43±0.10),s.gges.ing that Medicago plants.allocated more energy to s.oots.to optimize photos.nthes.s.when N was.not limiting. The s.oot-to-root ratios.were not s.gnificantly different between two CO2 levels.

We put forth Drama Theory II （DT II） as.a formal multiple participant decis.on making framework that can be us.d to s.s.ematically model complex s.curity challenges. and advance the field of s.s.ainable s.curity s.s.ems.Engineering. DT II is.defined as.a theory of ＂large world＂ pre-game communication and equilibrium s.lection. While game theoretic tools.have been widely applied to res.lve environmental conflicts.and promote global s.curity, traditional game theory as.umes.that decis.on makers. options. and preferences.are fixed. A mathematical treatment of key drama theoretic concepts.（i.e. pos.tions. intentions. doubts.and dilemmas. is.provided. The dynamics.of the drama theoretic proces. are dis.us.ed and the expected equilibrium s.t is.derived. The fundamental theorem of drama theory is.proven and all theoretical res.lts.are applied to promote s.s.ainable s.curity s.lutions. It is.emphas.zed that DT II repres.nts.a flexible s.s.ems.engineering technique to addres. time-s.ns.tive, multi-faceted, and complex multiple participant negotiations.

River morphology has.been a s.bject of great challenge to s.ientis.s.and engineers.who recognize that any effort with regard to river engineering mus. be bas.d on a proper unders.anding of the morphological features.involved and the res.ons.s.to the impos.d changes. In this.paper, an overview of river morphology is.pres.nted from the geomorphic viewpoint. Included in the s.ope are the regime concept, river channel clas.ification, thres.olds.in river morphology, and geomorphic analys.s.of river res.ons.s. Analytical approach to river morphology bas.d on the phys.cal principles.for the hydraulics.of flow and s.diment trans.ort proces.es.is.als. pres.nted. The application of analytical river morphology is.demons.rated by an example. Modeling is.the modern technique to determine both s.ort-term and long-term river channel res.ons.s.to any change in the environment. The phys.cal foundation of fluvial proces.-res.ons. mus. be applied in formatting a mathematical model. A brief introduction of the mathematical model FLUVIAL-12 is.des.ribed.
