In the present paper a vibrational d.fferential equation governing on a rigid.beam.on viscoelastic found.tion has been investigated. The nonlinear d.fferential equation governing on this vibrating system.is solved.by a sim.le and.innovative approach, which has been called.Akbari-Ganji＇s m.thod.（AGm.. AGm.is a very suitable com.utational process and.is usable for solving various nonlinear d.fferential equations. m.reover, using AGm.which solving a set of algebraic equations, com.licated.nonlinear equations can easily be solved.without any m.them.tical operations. Also, the d.m.ing ratio and.energy lost per cycle for three cycles have been investigated. Furtherm.re, com.arisons have been m.d. between the obtained.results by num.rical m.thod.（Runk45） and.AGm. Results showed.the high accuracy of AGm. The results also showed.that by increasing the am.unt of initial am.litud. of vibration （A）, the value of d.m.ing ratio will be increased. and.the energy lost per cycle d.creases by increasing the num.er of cycle. It is conclud.d.that AGm.is a reliable and.precise approach for solving d.fferential equations. On the other hand. it is better to say that AGm.is able to solve linear and.nonlinear d.fferential equations d.rectly in m.st of the situations. This m.ans that the final solution can be obtained.without any d.m.nsionless proced.re Therefore, AGm.can be consid.red.as a significant progress in nonlinear sciences.

Evaluating the Effect of Tillage on Carbon Sequestration Using the m.nim.m.d.tectable d.fference Concept

Three long-term.field.trials in hum.d.regions of Canad. and.the USA were used.to evaluate the influence of soil d.pth and.sam.le num.ers on soil organic carbon (SOC) sequestration in no-tillage (NT) and.m.ld.oard.plow (m.) corn (Zea m.ys L.) and.soybean (Glycine m.x L.) prod.ction system.. The first trial was cond.cted.on a m.ryhill silt loam.(Typic Haplud.lf) at Elora, Ontario, Canad., the second.on a Brookston clay loam.(Typic Argiaquoll) at Wood.lee, Ontario, Canad., and.the third.on a Thorp silt loam.(Argiaquic Argialboll) at Urbana, Illinois, USA. No-tillage led.to significantly higher SOC concentrations in the top 5 cm.com.ared.to m. at all 3 sites. However, NT resulted.in significantly lower SOC in sub-surface soils as com.ared.to m. at Wood.lee (10-20 cm. P = 0.01) and.Urbana (20-30 cm. P d.significantly m.re SOC storage than m. at the Elora site (3.3 m. C ha-1) and.at the Wood.lee site (6.2 m. C ha-1) on an equivalent m.ss basis (1350 m. ha-1 soil equivalent m.ss). Sim.larly, NT had.greater SOC storage than m. at the Urbana site (2.7 m. C ha-1) on an equivalent m.ss basis of 675 m. ha-1 soil. However, these d.fferences d.sappeared.when the entire plow layer was evaluated.for both the Wood.lee and.Urbana sites as a result of the higher SOC concentrations in m. than in NT at d.pth. Using the m.nim.m.d.tectable d.fference technique, we observed.that up to 1500 soil sam.le per tillage treatm.nt com.arison will have to be collected.and.analyzed.for the Elora and.Wood.lee sites and.over 40 soil sam.les per tillage treatm.nt com.arison for the Urbana to statistically separate significant d.fferences in the SOC contents of sub-plow d.pth soils. Therefore, it is im.racticable, and.at the least prohibitively expensive, to d.tect tillage-ind.ced.d.fferences in soil C beyond.the plow layer in various soils.
