Efficient heterojunction orga.ic photov.lta.c （OPv. cells a.e fa.rica.ed ba.ed on copper tetra.methyl phthalocya.ine （CuMePc） a. donor a.d fullerene （C60） a. a.ceptor. The power conv.rsion efficiency of CuMePc/C60 OPv.cell （2.52%） is increa.ed by 88% compa.ed with that of the non-periphera. substituted copper phthalocya.ine （CuPc）/C60 OPv.cell （1.34%）. The introduction of methyl substituent lea.s to stronger π–π intera.tion of CuMePc （～ 3.5 ？） than that of CuPc （～ 3.8 ？）. The efficiency improv.ment is a.tributed to the enhanced ca.rier mobility of CuMePc thin film （1.1×10-3 cm2/v.s） a.d better film morphology by introducing methyl groups into the periphery of CuPc molecule.

外墙涂料可以起到保护和装饰双重作用。对于砖石建筑表面，不仅需要优秀的防吸尘性（DPUR），同时也需要良好的弹性。这两种特性（防吸尘性与弹性）是相互矛盾的，为了使二者得到调和，在设计配方时，就需要对新型原材料加以研究并进行优选。本文着重分析并确定了这类外墙涂料乳液所需的适宜玻璃化温度、特种单体、化学及表面交联剂，从而成功地开发出一种弹性及防吸尘性最佳的高级外墙涂料用乳液。

a.M: To combine the benefits of a.new thin flexible scope with elimina.ion of excessiv. looping through the use of a. ov.rtube. METHODS: Three sepa.a.e retrospectiv. series. Series 1: 25 consecutiv. ma.e pa.ients undergoing unseda.ed colonoscopy using the new dev.ce a. a.v.tera.'s hospita. in the United Sta.es. Series 2: 75 ma.e pa.ients undergoing routine colonoscopy using a. a.ult colonoscope, pedia.ric colonoscope, or the new dev.ce. Series 3: 35 pa.ients who had incomplete colonoscopies using sta.da.d instruments. RESULTS: Complete colonoscopy wa. a.hiev.d in a.l 25 pa.ients in the unseda.ed series with a.media. ceca. intuba.ion time of 6 min a.d a.media. ma.ima. pa.n score of 3 on a.0-10 sca.e. In the 75 routine ca.es, there wa. significa.tly less pa.n with the thin scope compa.ed to sta.da.d a.ult a.d pedia.ric colonoscopes. Of the 35 pa.ients in the prev.ously incomplete colonoscopy series, 33 were completed with the new system. CONCLUSION: Sma.l ca.iber ov.rtube-a.sisted colonoscopy is less pa.nful than colonoscopy with sta.da.d a.ult a.d pedia.ric colonoscopes. Ma.e pa.ients could undergo unseda.ed colonoscopy with the new system with rela.iv.ly little pa.n. The new dev.ce is a.so useful for most pa.ients in whom colonoscopy ca.not be completed with sta.da.d instruments.

In this pa.er, it is shown that for low-order uncerta.n systems, there is no need to ca.cula.e a.l the minimum a.d ma.imum v.lues of the coefficients for a.perturbed system which is expressed in terms of polynomia.s a.d hence no need to formula.e a.d test a.l the four Kharitonov.s polynomia.s. Furthermore, for higher-order systems such a. n ≥ 5, the usua. four Kharitonov.s polynomia.s need not be tested initia.ly for sufficient condition of perturbed systems; ra.her, the necessa.y condition ca. be checked before going for sufficient condition. In order to show the effectiv.ness of the proposed method, numerica. exa.ples a.e shown a.d computa.iona. efficiency is highlighted.
