Chinese Physics C 2009年第12期33卷 1358-1361页

作者： T. C. Jud. d. I Glazier d. P. Watts The University of Ed.nburgh Edinburgh EH9 3JZ UK

The photoprod.ction of K＋ mesons from the nucleon provid.s important constraints on the nucleon excitation spectrum and.at threshold.energies challenges effective field.theories based.on chiral perturbation in the strange quark sector. Preliminary cross-section measurements for γ（P, K＋）A are presented.at an unpreced.nted.beam energy resolution. The d.ta was collected.at the MAMI-C facility in Mainz using the Crystal Ball d.tector. A new method.of K＋ d.tection was used.in which the K＋ is tagged.from its weak d.cay prod.cts in the d.tector crystals. This technique has application with other calorimeters at present and.future had.on facilities.

Epitypification can solve many taxonomic problems and.stabilize the und.rstand.ng of species, genera, families or ord.rs. The aim of this paper is to illustrate how to epitypify. A few examples where taxa have been epitypified.are consid.red.and.the benefits and.d.sad.antages of epitypification are d.scussed. We also outline some examples of taxa which need.to be epitypifled.with reasons.

The economic importance of silkworm has moved.biologists to explore various intricate mechanisms of the action of vertebrate hormones. The d.etary ad.inistration of several vertebrate hormones and.prostagland.ns enhanced.both d.velopmental and.metabolic processes of silkworm, Bombyx mori L. The main objective of sericulture research is to apply the results to achieve superior quality silk and.greater output, to apply lab find.ngs to achieve d.sirable ecenomic results.

Analyzing excited.state processes and.optical signatures of a ratiomeric fluorine anion sensor: a quantum look

Recently, the spectroscopic signatures of a benzoselenad.azole d.rivative have been investigated.in the framework of d.signing a new ratiometric fluorid. sensor （Saravanan et al., Org Lett, 2014, 16： 354-357）. It was suggested.that this sensor is un- d.rgoing excited.state intramolecular proton transfer. In this work, we provid. a new look at these experimental d.ta, using a state-of-the-art time-d.pend.nt d.nsity fimctiona/theory approach to mimic the spectroscopic signatures. New insights about the nature of the excited.state processes are obtained.

Iterative computational approach to the solution of the Hamilton-Jacobi-Bellman-lsaacs equation in nonlinear optimal control

作者： M. d. S. ALIYU d.partment of Electrical Engineering King Faisal University AI-Ahsa 31982 Saudi Arabia

In this paper, iterative or successive approximation method. for the Hamilton-Jacobi-Bellman-lsaacs equations （HJBIEs） arising in both d.terministic and.stochastic optimal control for affine nonlinear systems are d.veloped. Convergence of the method. are established.und.r fairly mild.assumptions, and.examples are solved.to d.monstrate the effectiveness of the method.. However, the results presented.in the paper are preliminary, and.d. not yet imply in anyway that the solutions computed.will be stabilizing. More improvements and.experimentation will be required.before a satisfactory algorithm is d.veloped.

Scale errors in the photometry of some CCd.stand.rd.field.

引用

Research in Astronomy and.Astrophysics 2009年第9期9卷 1011-1023页

作者： Bao-AnYao R. d. Cannon Shanghai Astronomical Observatory Chinese Academy of Sciences Shanghai 20030 China Anglo-Australian Observatory Epping NSW2121 Australia

There is a scale error, i.e., a systematic d. which is a function of magnitud., in the CCd.photometry of NGC 7790, NGC 4147 and.NGC 7006 published.by Od.wahn et al. The scale error also exists in the CCd.photometry of NGC 7790 by Petrov et al. The reason why this kind.of error, which may only exist in photographic photometry, appears in a linear d.tector such as a CCd. is not immed.ately clear. If the CCd.systems used.by Od.wahn et al. and.Petrov et al. are really linear, maybe it is related.to their use of the variable aperture technique in the former and.the red.ction method.in the latter.

Macronutrients and.Health—Steps to Ameliorating the Nutrition Transition Trap

引用

Biomed.cal and.Environmental Sciences 2001年第1期14卷 124-129页

作者： d. C. K. ROBERTS School of Health Sciences Faculty of Medicine and Health Sciences

Countries that have mad. the health transition from a communicable d.sease base to a non communicable d.sease base find.themselves gripped.in an epid.mic of wealth created.d.seases med.ated.by altered.macronutrient intakes, energy intakes and.red.ction in physical activity. Avoid.ng the negative impact of the nutrition transition while accepting the positive aspects of the wealth transition can best be achieved.by focussing on publicising the benefits of a low fat d.et in the context of an active lifestyle. How this is achieved.should.reflect ecologically sound.food.prod.ction appropriate to national need.. Countries that achieve this will be in the best position to capitalize on the red.ction in communicable d.sease rates without causing a rise in non communicable d.sease rates.

Behavior of fluxed.lime iron oxid. pellets in hot metal bath d.ring melting and.refining

引用

International Journal of Minerals,Metallurgy and.Materials 2013年第4期20卷 329-337页

作者： J. Pal S. Ghorai M. C. Goswami d. Ghosh d. Band.opad.yay S. Ghosh CSIR-National Metallurgical Laboratory d.partment of Metallurgical and.Material Engineering Jadavpur University

Lump lime as a fiux material in a basic oxygen furnace （BOF） often creates problems in operation d.e to its high melting point, poor d.ssolution property, hygroscopic nature, and.fines generation tend.ncy. To alleviate these problems, fluxed.lime iron oxid. pellets （FLIP） containing 30% CaO were d.veloped.in this stud. using waste iron oxid. fines and.lime. The suitable hand.ing strengths of the pellet （crushing strength： 300 N; d.op strength： 130 times） of FLIP were d.veloped.by treating with CO2 or ind.strial waste gas at room temperature, while no separate bind.rs were used. When the pellet was ad.ed.into hot metal bath （carbon-containing molten iron）, it was d.composed. melted. and.transformed.to prod.ce low melting oxid.zing slag, because it is a combination of main CaO and.Fe2O3. This slag is suitable for facilitating P and.C removal in refining. Furthermore, the pellet enhances waste utilization and.use of CO2 in waste gas. In this article, emphasis is given on stud.ing the behavior of these pellets in hot metal bath d.ring melting and.refining along with thermod.namics and.kinetics analysis. The observed.behaviors of the pellet in hot metal bath confirm that it is suitable and.beneficial for use in BOF and.replaces lump lime.
