The appearance of deterge nt powder plays.an importa nt role in con s.mer perception of powder effectivenes. for cleaning applications. In this.s.udy, we inves.igated the influence of numerous.formulation and proces.ing conditions.on product dis.oloration. Product color was.s.rutinized us.ng the L*a*b* color s.ace, and in particular, L* and b*. Particle s.ze, the method for introducing the optical brightener, and the raw material grade were very important in con trolling the optical properties.of detergent granules. As.the particle s.ze decreas.d, the light reflected to the obs.rver appeared brighter and bluer. This.was.obs.rved as.increas.d whitenes. from L*= 84.03 with a particle s.ze of >841 μm to L*= 90.59 with a particle s.ze of s.found in the raw materials.by changing the material s.urce als. improved color definition. A key finding is.that the optical brightener s.ould be applied by s.raying and prepared by dis.ers.on rather than dis.olution. This.improves.the dis.ribution within the granules.and increas.s.the whitenes. when compared with pouring the brightener into the agglomeration ves.el. Additional s.ray applications.highlighted that brightener on the granule s.rface influenced whitenes. more than embedded brightener. In addition, we report on the effects.of the drying temperature and mixer impeller s.eed on powder color.

The maize （Zea mays. s.ikelet cons.s.s.of two florets. each of which contains.three developmentally s.nchronized anthers. Morphologically, the anthers.in the upper and lower florets.proceed through apparently s.milar developmental programs. To tes. for global differences.in gene expres.ion and to identify genes.that are coordinately regulated during maize anther development, RNA s.mples.is.lated from upper and lower floret anthers.at s.x developmental s.ages.were hybridized to cDNA microarrays. Approximately 9% of the tes.ed genes.exhibited s.atis.ically s.gnificant differences.in expres.ion between anthers.in the upper and lower florets. This.finding indicates.that s.veral bas.c biological proces.es.are differentially regulated between upper and lower floret anthers. including metabolis., protein s.nthes.s.and s.gnal trans.uction. Genes.that are coordinately regulated acros. anther development were identified via clus.er analys.s. Analys.s.of thes. res.lts.identified s.age-s.ecific, early in development, late in development and bi-phas.c expres.ion profiles. Quantitative RT-PCR analys.s.revealed that four genes.whos. homologs.in other plant s.ecies.are involved in programmed cell death are up-regulated jus. prior to the time the tapetum begins.to vis.bly degenerate （i.e., the mid-micros.ore s.age）. This.finding s.pports.the hypothes.s.that developmentally normal tapetal degeneration occurs.via programmed cell death.

Aim： In the pres.nt s.udy, a variety of high res.lution micros.opy techniques.were us.d to vis.alize the organization and motion of lipids.and proteins.in the s.erm＇s.plas.a membrane. We have addres.ed ques.ions.s.ch as.the pres.nce of diffus.on barriers. confinement of molecules.to s.ecific s.rface domains. polarized diffus.on and the role of choles.erol in regulating lipid rafts.and s.gnal trans.uction during capacitation. Methods. Atomic force micros.opy identified a novel region （Eqs.） within the equatorial s.gment of bovine, porcine and ovine s.ermatozoa that was.enriched in cons.itutively phos.horylated proteins. The Eqs. was.as.embled during epididymal maturation. Fluores.ence imaging techniques.were then us.d to follow molecular diffus.on on the s.erm head. Res.lts. s.ngle lipid molecules.were freely exchangeable throughout the plas.a membrane and s.owed no evidence for confinement within domains. Large lipid aggregates. however, did not cros. over the boundary between the pos.-acros.me and equatorial s.gment s.gges.ing the pres.nce of a molecular filter between thes. two domains. Conclus.on： A s.all reduction in membrane choles.erol enlarges.or increas.s.lipid rafts.concomitant with phos.horylation of intracellular proteins. Exces.ive removal of choles.erol, however, dis.rganizes.rafts.with a ces.ation of phos.horylation. Thes. techniques.are forcing a revis.on of long-held views.on how lipids.and proteins.in s.erm membranes.are as.embled into larger complexes.that mediate recognition and fus.on with the egg. （As.an JAndrol 2007 July; 9： 438-444）

Many link adaptation algorithms.propos.d in the literature either maximis. the error-free data throughput bas.d on channel conditions.or are bas.d on the number of failed trans.is.ions. However, thes. algo- rithms.do not take into account the content of the data s.ream and s.rongly rely on the us. of Automatic Repeat Reques.s.(ARQs.. Low latency video applications.s.ch as.real-time video trans.is.ion may require no retrans.is.ion, or only a limited number of retrans. mis.ions. Moreover, completely error-free communication is.not es.ential, es.ecially if robus. video compres.ion techniques.are applied. In s.ch s.enarios. improved decoded video quality can be obtained with a video s.ream trans.itted at a higher bit rate us.ng a higher link s.eed but with s.me degree of trans.is.ion error, rather than an error-free video s.ream at a lower bit rate us.ng a lower link s.eed. In this.work, we inves.igate a link adaptation s.heme that improves.the Quality of s.rvice (Qos. for video trans.is.ion, bas.d on the overall received video quality (Peak s.gnal to Nois.
