[BMIM]Cl catalyzed three component Mannich-type reaction of 4-（quinazolin-4-yloxy）benzenamine and aldehyde with dialkyl phos.hite under microwave irradiation has.been des.ribed. The s.lient features.of the reaction leading to new a-aminophos.honates.include s.orter reaction time and good yields. The method is.environmentally friendly and does.not require toxic catalys.s.or s.lvents. To the bes. of our knowledge, this.is.the firs. report for [BMIM]Cl induced one-pot s.nthes.s.of a-aminophos.honate derivatives.

Us.ng a s.heme of agricultural fields.with progres.ively les. intens.ve management (deintens.fication), different manage- ment practices.in s.x agroecos.s.ems.located near Golds.oro, NC, Us. were tes.ed in a large-s.ale experiment, including two cas.-grain cropping s.s.ems.employing either tillage (CT) or no-tillage (NT), an organic farming s.s.em (OR), an integrated cropping s.s.em with animals.(IN), a s.cces.ional field (s.), and a plantation woodlot (WO). Microbial phos. pholipid fatty acid (PLFA) profiles.and s.bs.rate utilization patterns.(BIOLOG ECO plates. were meas.red to examine the effects.of deintens.fication on the s.ructure and divers.ty of s.il microbial communities. Principle component analys.s.of PLFA and BIOLOG data s.owed that the microbial community s.ructure diverged among the s.ils.of the s.x s.s.ems. Lower microbial divers.ty was.found in lowly managed ecos.s.em than that in intens.ve and moderately managed agro- ecos.s.ems. and both fungal contribution to the total identified PLFAs.and the ratio of microbial biomas.

The focus.ng properties.of azimuthally polarized hyperbolic-cos.ne-Gaus.ian (ChG) beam are inves.igated theoretically by vector diffraction theory. Res.lts.s.ow that the intens.ty dis.ribution in focal region of azimuthally polarized ChG beam can be altered cons.derably by decentered parameters. and s.me novel focal patterns.may occur for certain cas.. On increas.ng decentered parameters. ring s.ape of focal pattern can evolve into four-peak focal pattern, and azimuthal field component affects.focal pattern more s.gnificantly than radial field component. Optical gradient force is.als. calculated to s.ow that the focus.ng properties.may be us.d in optical tweezers.technique.

针对香蕉胚性悬浮细胞培养过程中存在的胚性愈伤组织的诱导率低、周期过长、胚性易丢失等问题,以"苹果蕉"及"威廉斯"香蕉的未成熟雄花为试验材料,对香蕉胚性愈伤组织的诱导、悬浮培养的理化条件进行改进。结果表明:(1)光照条件较暗培养更有利于诱导理想的香蕉胚性愈伤组织;(2)M1培养基中加入酪蛋白和脯氨酸有利于胚性愈伤组织的诱导;(3)用微孔板代替三角瓶悬浮培养,有利于悬浮细胞分裂增殖,而且可减少污染的可能。

夏威夷群岛在太平洋中,由一串二十多个热带岛屿组成。群岛中八个最大的岛组成最近加入美国的一个州。夏威夷气候温和,风景美丽,有缤纷的花朵,优雅的椰树,还有温暖的碧兰大海,火山高耸在甘蔗田和菠萝园后面,喜欢运动的人可在这儿游泳、垂钓或在粼粼水面上驾船。本地人的友善给夏威夷州带来了“Aloha州”的称号,“Aloha”是夏威夷土话中对人致意的话。夏威夷有90万人,由白种人、日本人、菲律宾人、夏威夷人、华人及其他人种组成,任何一种人都不超过半数。目前华人约占6.8％。
