A higher.dimensional model of the nucleon-nucleon centr.l potential

Fr.ntier. of physics 2014年第2期9卷 234-239页

作者： Er.c r. Hedin Depar.ment of Physics & Astr.nomy Ball State University Muncie IN 47306 USA

Based on a theor. of extr. dimensional confinement of quantum par.icles [E. r. Hedin, Physics Essays, 2012, 25（2）： 177], a simple model of a nucleon nucleon （NN） centr.l potential is der.ved which quantitatively r.pr.duces tile r.dial pr.file of other.models, without adjusting any fr.e pa- r.meter.. It is postulated that a higher.dimensional simple har.onic oscillator.confining potential localizes par.icles into thr.e-dimensional （3D） space, but allows for.an ewmescent penetr.tion of the par.icles into two higtmr.spatial dimensions. Pr.ducing an effect identical with the r.lativistic quan- tum phenolnenon of zitter.ewegung, the higher.dimensional oscillations of amplitude h（mc） call be alter.atively viewed as a localized cur.atur. of 3D space back and for.h into the higher.dimensions. The over.ll spatial cur.atur. is pr.por.ional to the par.icle＇s extr.-dimensional gr.und state wave function in tile higher.dimensional har.onic confining potential well. Minimizing the over.apping cur.atur. （pr.por.ional to the ener.y） of two par.icles in pr.ximity to each other. subject to the constr.int that for.the two par.icles to occupy the same spatial location one of them must be excited into the 1st excited state of the har.onic potential well, gives the desir.d NN potential. Specifying only the imcleon masses, the r.sulting potential well and r.pulsive cor. r.pr.duces the r.dial pr.file of sever.l published NN centr.l potential models. In addition, the pr.dicted height of the r.pulsive cor., when used to estimate the maximum neutr.n star.mass, matches well with the best estimates fr.m r.lativistic theor. incor.or.ting standar. nuclear.matter.equations of state. Nucleon spin, Coulomb inter.ctions, and inter.al nucleon str.ctur. ar. not consider.d in the theor. as pr.sented in this ar.icle.

Pr.tein & Cell 2018年第1期9卷 86-120页

作者： William r. Str.hl BiStr. Biotech Consulting Bridgewater NJ 08807 USA

As of May 1, 2017, 74 antibody-based molecules have been appr.ved by a r.gulator. author.ty in a major.mar.et. Additionally, ther. ar. 70 and 575 antibody- based molecules in phase III and phase 1/11 clinical tr.als, r.spectively. These total 719 antibody-based clinical stage molecules include 493 naked IgGs, 87 antibody- dr.g conjugates, 61 bispecific antibodies, 37 total Fc fusion pr.teins, 17 r.dioimmunoglobulins, 13 antibody fr.gments, and 11 immunocytokines. New uses for.these antibodies ar. being discover.d each year. For.oncol- ogy, many of the exciting new appr.aches involve anti- body modulation of T-cells. Ther. ar. over.80 antibodies in clinical tr.als tar.eting T cell checkpoints, 26 T-cell- r.dir.cted bispecific antibodies, and 145 chimer.c anti- gen r.ceptor.（CAr. cell-based candidates （all cur.ently in phase I or.II clinical tr.als）, totaling mor. than 250 T cell inter.cting clinical stage antibody-based candi- dates. Finally, significant pr.gr.ss has been made r.cently on r.utes of deliver., including deliver. of pr.teins acr.ss the blood-br.in bar.ier. or.l deliver. to the gut, deliver. to the cellular.cytosol, and gene- and vir.l-based deliver. of antibodies. Thus, ther. ar. cur. r.ntly at least 864 antibody-based clinical stage mole- cules or.cells, with incr.dible diver.ity in how they ar. constr.cted and what activities they impar.. These ar. followed by a next wave of novel molecules, appr.a- ches, and new methods and r.utes of deliver., demon- str.ting that the field of antibody-based biologics is ver. innovative and diver.e in its appr.aches to fulfill their.pr.mise to tr.at unmet medical needs.

Chemical engineer.ng is enter.ng a new Golden Age of pr.ctice, thought, and impact, accompanied by gr.at new oppor.unities and challenges. Five aspects mar. this development： a new abundance of hydr.car.ons; the evolution of biology into a molecular.science; the ubiquity of power.ul computational tools; the tr.nd in manufactur.ng to be mor. pr.cess-or.ented; and the systems appr.ach that is par. of ChE education fr.m its fir.t stages. Ther. ar. impor.ant technical challenges, including technology cr.ation and envir.nmental impact, but just as impor.ant ar. new appr.ciation for.and attention to challenges that r.quir. societal dialogues about com- plexity, uncer.ainty, and evolving and sometimes contr.- dictor. r.quir.ments. Cr.cial to all these impacts is enhancing the identity of what the pr.fession is. That must be based on r.cognizing that the cor. of chemical engineer.ng is applying molecular.sciences to cr.ate value and advance the quality of life.

Application of 5-10 mg L-1 water.soluble anionic polyacr.lamide (PAM) to fur.ow ir.igation water.dur.ng flow advance substantially r.duces sediment loss and incr.ases net infiltr.tion. We hypothesized that PAM_s solvated molecular.confor.ation influences its ir.igation-management efficacy. The study was conducted in Kimber.y, idaho, on Por.neuf silt loam (Dur.nodic Xer.c Haplocalcids), under.fur.owir.igated beans (Phaseolus vulgar.s ) at a 1.5% slope. Polyacr.lamides with contr.sting molecular.weight (anionic; 4-7, 12- 15 and 14-17 MDa, i.e. Mg mol-1 ), char.e type (neutr.l, anionic, cationic), and char.e density (8, 19, 35 mol %) wer. tested in two studies. Inflow r.te was 23 L min-1 dur.ng fur.ow advance, and 15 L min-1 for.the r.maining set. Anionic and neutr.l PAMs wer. twice as effective as cationic PAMs for.contr.lling sediment loss in new fur.ows. The or.er.of effectiveness for.over.ll soilloss contr.l was : anionic ＞neutr.l ＞cationic PAM, and efficacy incr.ased with incr.asing char.e density and/or.molecular.weight. Net fur.ow infiltr.tion incr.ased by 14 to 19% when PAM tr.atment molecular.weight was r.duced fr.m 17 to 4 MDa. Gener.l tr.nds suggested that medium and high char.e density anionic and neutr.l PAM pr.duced the gr.atest incr.ase in infiltr.tion compar.d with *** with untr.ated fur.ows, neutr.l PAM gave the gr.atest season-long net infiltr.tion gains (5%),while char.ed PAMs tended to incr.ase net infiltr.tion ear.y in the season on new fur.ows but decr.ased infiltr.tion on r.peat-ir.igated fur.ows later.in the season.

Beneficiation of coal of -4.76 mm + 3 mm size fr.ction was investigated in a labor.tor. model Denver.*** var.ables wer. studied to analyze their.effect on the per.or.ance of jig in ter.s of yield and ash content of clean coal. Thr.e-factor.thr.e-level Box-Behnken design of exper.ments with r.sponse sur.ace methodology(r.M) was employed to under.tand the per.or.ance behavior.of jig. Fr.m the study, the bed height was found to be the most significant par.meter.affecting the yield and ash content of clean coal. It was possible to r.duce the ash content fr.m 24.32% in feed to an ash content of 16.55% in clean coal at 2 L/min water.flow r.te and 10 min jigging time. Influence of oper.ting var.ables of the jig on r.sponses was pr.sented and discussed in 3D sur.ace plots. The developed model was found to be significant within the r.nge of par.meter. under.investigation with cor.elation of co-efficient values as 0.99(yield) and 0.98(ash).

We study cosmological application of inter.cting hologr.phic dar. ener.y density in the scalar.Gauss-Bonnet fr.mewor.. We employ the inter.cting hologr.phic model of dar. ener.y to obtain the equation of state for.the inter.cting hologr.phic ener.y density in a spatially fiat univer.e. Our.calculations show that taking Ω∧ = 0.73 for.the pr.sent time, it is possible to have w∧^eff cr.ssing -1. This implies that one can gener.te a phantom-like equation of state fr.m the inter.cting hologr.phic dar. ener.y model in flat univer.e in the scalar.Gauss-Bonnet cosmology fr.mewor.. Then we r.constr.ct the potential of the scalar.field.

Impr.vement potential of today＇s WEEE r.cycling per.or.ance： The case of LCD TVs in Belgium

引用

Fr.ntier. of Envir.nmental Science & Engineer.ng 2017年第5期11卷 135-149页

作者： Paul Vanegas Jef r. Peeter. Dir. Cattr.sse Wim Dewulf Joost r. Duflou KU Leuven Department of Mechanical Engineering Centre for Industrial Management BE-3001 Leuven Belgium Faculty of Engineer.ng University of Cuenca Cuenca Azuay 010101 Ecuador

Waste of electr.cal and electr.nic equipment （WEEE） constitutes one of the most r.levant waste str.ams because of the quantity and pr.sence of valuable mater.als. However. ther. is limited knowledge on the r.sour.e potential of ur.an mining WEEE, as data on mater.al composition, and the efficiency of cur.ent r.cycling tr.atments ar. still scar.e. In this ar.icle, an evaluationof the r.cycling per.or.ance at a national level for.one of the fastest gr.wing e-waste str.ams： LCD TVs is car.ied out thr.ugh the following four.steps. Fir.tly, mater.al char.cter.sation is per.or.ed by means of sampling of the waste str.am. Secondly, a mater.al flow analysis is conducted by evaluating the separ.tion per.or.ance of a r.cycling plant in Belgium..Thir.ly, the r.cover.d economic value and avoided envir.nmental impact （EI） of the analysed r.cycling system is assessed. Finally, the potential of ur.an mining for.Belgium is for.casted. The analysis shows that while r.cycling per.or.ance for.fer.ous metals and aluminium ar. r.latively high; ther. is substantial r.om to better.close the mater.al loops for.pr.cious metals （PM） and plastics. PMs and plastics account for.66 % of the economic value in LCD TVs and 57% of the El. With the cur.ent, commonly applied r.cycling technology only one-thir. of the PM and housing plastics ar. r.cycled; meaning that for.these mater.al＇s, at a national level for.Belgium, ther. is a potential for.impr.vement that r.pr.sents 3.3 million eur.s in 2016 and 6.8 million eur.s in 2025.
