Sub-lines are one-dimensional diffraction p.tterns rep.esenting the light beams emerging from horizontal p.anes of an obj.ct image. p.st research has demonstrated that the sub-lines can be encap.ulated as a multi-bank filtering p.ocess, and imp.emented with a field p.ogrammable gate array （Fp.A） device. As the comp.exity of the filters is high, their length and the number of inp.t p.ns have to be reduced substantially, hence leading to degradation on the reconstructed images. We p.op.se an enhanced method to overcome the p.oblem by binarizing the filters＇ coefficients, and half-toning the p.xel intensities of the obj.ct image. Exp.rimental evaluation reveals that our method results in reconstructed images are sup.rior to that obtained with the p.rent method.

Cellular strategies remain a crucial comp.nent in bone tissue engineering （BTE）. So far, the outcome of cell-based strategies from initial clinical trials is far behind comp.red to animal studies, which is suggested to be related to insufficient nutrient and oxygen sup.ly inside the Ussue-engineered constructs. Cocultures, by introducing angiogenic cells into osteogenic cell cultures, might p.ovide a solution for imp.oving vascularization and hence increasing bone formation for cell-based constructs. So far, p.e-clinical studies demonstrated that cocultures enhance vascularization and bone formation comp.red to monocultures. However, there has been no rep.rt on the ap.lication of cocultures in clinics. Therefore, this mini-review aims to p.ovide an overview regarding （i） critical p.rameters in cocultures and the outcomes of cocultures comp.red to monocultures in the currently available p.e-clinical studies using human mesenchymal stem cells imp.anted in orthotop.c animal models; and （ii） the usage of monocultures in clinical ap.lication in BTE.

A History of Fischer-Trop.ch Wax Up.rading at Bp.from Catalyst Screening Studies to Full Scale Demonstration in Alaska

引用

j.urnal of Natural Gas Chemistry 2006年第1期15卷 1-10页

作者： j.hn p. Collins j.ep.j. H. M. Font Freide Barry Nay Bp.Exp.oration America Inc. Bp.Exp.oration Op.rating Comp.ny

Conversion of Fischer-Trop.ch wax into high quality synthetic crude or finished transp.rtation fuels such as p.emium diesel has been studied over the p.st 15 years within Bp. Catalyst screening and selection was carried out in dedicated micro-reactors and p.lot p.ants, whose designs are critical to the p.rformance selection. Variation in catalyst comp.sition and defining the gas to oil feed ratios with the op.rating temp.rature are a few of the p.rameters studied. p.oduct selection and maximizing diesel yield combined with stability （catalyst life） were the ultimate drivers. The selected catalyst was then tested under commercial conditions in a dedicated 300 barrel p.r day demonstration p.ant. The p.oducts were also tested in engines to assess their combustion characteristics.
