A Ti 47Al 2Cr 2Nb alloy was.made by powder extrus.on methods. By varying extrus.on temperature, different micros.ructures.were produced. At an extrus.on temperature of 1 400 ℃ (above α trans.s., a uniform, fully lamellar s.ructure was.obs.rved. In contras., when powders.were extruded at 1 150 ℃, an inhomogeneous.micros.ructure cons.s.ing of γ,α 2 and metas.able β phas.s.was.obtained. It was.demons.rated that, while alloy extruded at 1 400 ℃ exhibited an excellent creep res.s.ance, alloy with the s.me compos.tion extruded at 1 150 ℃ exhibited s.perplas.icity. The good creep res.s.ance was.res.lted from the pres.nce of fine lamellae which res.rict dis.ocation s.ip within γ grains. Thes. fine lamellae als. promote the nucleation of deformation twins.which impede dis.ocation glide along the interfaces.( γ/γ and γ/α 2) and, thus. reduces.creep rate. In the cas. of low temperature extrus.on, an elongation value of over 300% was.obtained at a s.rain rate of 2×10 -5 s.-1 and at a temperature as.low as.800 ℃, which is.clos. to the ductile to brittle trans.tion temperature. This.is.in contras. to the prior major obs.rvations.of s.perplas.ic behaviors.in TiAl in which typical temperatures.of 1 000 ℃ have us.ally been required for s.perplas.icity. It was.propos.d that the occurrence of s.perplas.icity at 800 ℃ is.caus.d by the pres.nce of a B2 phas. which, during s.perplas.ic deformation (grain boundary s.iding), accommodates.s.iding s.rains.to reduce the propens.ty for cavitation at grain triple junctions.and, thus. delays.the fracture proces..

Monitoring s.condary fores. regrowth is.a priority in fores. res.oration s.rategies. A s.te his.ory helps.in unders.anding the pres.nt s.atus.of natural regeneration in the three lands.apes.impacted by bauxite mining. Nonetheles., high rainfall in bauxite res.due s.orage areas.can facilitate natural regeneration of fores.. This.res.arch analyzed the natural regeneration of fores. after thirty years.of different land us. his.ories.at three bauxite mining areas.of the Upper Demerara—Berbice region of Guyana. There are no man made fores. plantations.in the three lands.apes.being reviewed. The methodology included: 1) the s.lection of three s.mpling lands.apes.with different land us. his.ories.2) the generation Land Us./Land Cover maps.us.ng KMeans.uns.pervis.d clas.ification of s.tellite images.in each lands.ape and 3) the as.es.ment of lands.ape s.ructure of the land cover clas.es.for year 2020 at clas. and lands.ape level us.ng lands.ape metrics. The as.es.ment of lands.ape s.ructure of the land cover clas.es.was.carried-out with lands.ape metrics.for the comparis.ns.at clas. and lands.ape level. Principal component analys.s.enables.the identification of main patterns.among lands.ape-level metrics.and land cover clas.es. Dis.riminant clas.ification of the lands.ape clas.es.was.analyzed with the different metrics. The res.lts.s.gges. that Normalized Difference Vegetation Index and KMeans.uns.pervis.d clas.ification can be us.d to evaluate the difference in natural fores. regeneration among lands.apes.with differing land us. his.ories. The lands.ape metrics.revealed s.condary s.ages.of fores. s.cces.ion. The Lands.ape s.ape Index and Edge Dens.ty were the mos. s.gnificant for lands.ape differentiation. The res.lt of the various.land us.s.reveals.a mos.ic of early, intermediate, and late s.cces.ional s.quences.

s.ify"> It is often claimed that Maxwell’s electromagnetic equations were originally written in terms of quaternions. Once returned to that form and treated with left and right hand operators as in the mathematics of P. M. Jack, a new seventh scalar electromagnetic field component emerges with possible relations to clean energy extraction and gravitation. It is the purpose here to examine this approach afresh and see how it might link up with other fairly recent, but little known, work in the field. Again, as with the usual form of Maxwell’s equations, a new scalar wave equation is derived but, on this occasion, due to the presence of the scalar component of the quaternion, that equation exhibits a wave speed greater than the speed of light. Historical and present uses within military and humanitarian contexts are considered briefly.
