面点实践教学中工艺标准化探析

在当前面点教学中,大部分教师仍处于凭经验教学阶段,各类教学品种无定量的工艺参数和明确的质量标准,不同教师做法不一,且计量手段落后,概念模糊,制品质量不稳定,造成学生学习起来难度较大;实施面点工艺标准化教学,可使学生更快更好的掌握烹饪工艺和技能,同时增强了学生的标准化意识,为传统食品的工业化生产打好基础;工艺标准化是通过对教学品种的制作工艺进行定量研究,从它的原料性状、制作工艺、营养卫生、质量标准及饮食美学等几个方面着手,确定原料质量标准、制作工艺标准和产品质量标准来实现的。

Physical design method of MPSoC

Floorplan, clock network and power plan are crucial steps in deep sub-micron system-on-chip design. A novel di- agonal floorplan is integrated to enhance the data sharing between different cores in system-on-chip. Custom clock network con- taining hand-adjusted buffers and variable routing rules is constructed to realize balanced synchronization. Effective power plan considering both IR drop and electromigration achieves high utilization and maintains power integrity in our MediaSoC. Using such methods, deep sub-micron design challenges are managed under a fast prototyping methodology, which greatly shortens the design cycle.     

论李煜前期词与南唐亡国之关系

李煜的前期词与其性格是统一的,它们都受唐五代词风的影响,同时又是南唐社会的一个缩影,这些因素综合在一起,决定了南唐必然亡国的命运。本文就是从这个角度讨论了李煜前期词与其亡国的关系。     

Tandem Biocatalysis by CotA-TJ102@UIO-66-NH2 and Novozym 435 for Highly Selective Transformation of HMF into FDCA

2,5-Furandicarboxylic acid(FDCA) is a potential biorenewable chemical for applications including plastics, polyamides, drugs, etc. The selective biosynthesis of FDCA from 5-hydroxymethylfurfural(HMF) by a specific enzyme poses a great challenge. In this study, we reported an efficient strategy to produce FDCA from HMF by the tandem biocatalysis of laccase(Cot A-TJ102@UIO-66-NH_2) and Novozym 435. For the first step, a nanoparticle metal–organic framework was synthesized as a carrier to immobilize Cot A-TJ102@UIO-66-NH_2, which was assigned for the production of 5-formyl-2-furancarboxylic acid(FFCA) and featured an enzyme loading of 255.54 mg/g, specific activity of 135.90 U/mg, and solid loading ratio of 99.65%. Under optimal conditions, an ideal FFCA yield of 98.5% was achieved, and the Cot A-TJ102@UIO-66-NH_2 presented a high recycling capacity after 10 cycles. For the second step, Novozym 435 was applied for the further conversion of FFCA into FDCA, presenting a high FDCA yield of 95.5% under the optimized conditions. Novozym 435 also exhibited a high recyclability after eight cycles. As a result, the tandem biocatalysis strategy provided a 94.2% FDCA yield from HMF, indicating its excellence as a method for FDCA production.     

Investigation of iodine concentration in salt,water and soil along the coast of Zhejiang,China

Objective: We aim to describe the environment iodine concentration in salt, water and soil along Zhejiang Province coast in the China foreland. It will be helpful for us to judge whether this area is insufficient in iodine and universal iodized salt is necessary or not. Methods: We collected iodized salt samples, drinking water samples (tap water in the towns, and well water or spring water in the villages), water samples from different sources (ditches, lakes, rivers) and soil samples through random sampling in June, 2005. Salt, water and soil iodine was detected by arsenic-cerium redox method. Statistical analysis was expressed as mean±SEMby Windows SPSS 13.0. Results: (1) The iodine concentration in salt was 27.9±4.33 mg/kg (n=108). (2) Seventy-five water samples were collected. The water iodine value was 0.6～84.8 μg/L (mean of 11.66 μg/L). The watershed along the Qiantang River has significantly higher iodine content than the water in Lin'an in mountain area (P＜0.01). The iodine content and mean iodine content of tap water, well or spring water and natural water sources were 4.30±2.43 μg/L (n=34), 23.59±27.74 μg/L (n=19)and 12.72±10.72 μg/L (n=22) respectively. This indicated that among environmental water sources, the ditch iodine content was the highest with river water iodine being the lowest (P＜0.01). (3) Soil iodine value was 0.11～2.93 mg/kg (mean of 1.32 mg/kg).Though there was no statistical difference of soil iodine in different districts (P=0.131), soil iodine content correlated positively with water iodine content. Conclusion: Iodine concentration in salt accords with national policy of adding iodine in salt. Foreland has more iodine in water than mountain area. The data reflected that water and soil iodine in foreland area was not high, which suggests universal iodized salt should be necessary. Environment iodine has relatively close association with pollution.     

氯地酚和FSH对猕猴超数排卵的比较及其在兔输卵管内受精的研究

在不考虑月经周期的情况下连续灌喂氯地酚5天,每天50mg,第8天肌注hCG2000IU,对猕猴具有一定的卵泡超数发育作用,最多可使双侧卵巢共24个卵泡发育,最大卵泡直径5—6mm,但不同个体反应变化较大。FSH hCG超排方案(考虑或不考虑月经周期,连续肌注FSH6天,共80—90IU,第8天肌注hCG2500IU)比氯地酚效果较好,最多可使双侧卵巢共28个卵泡发育,卵泡最大直径10mm,另外在1只猕猴观察到5个卵泡破裂将卵排出。电刺激采得之猕猴精子经洗涤后与用以上两种超排方案以卵泡吸得之卵子一同输入兔输卵管进行受精,获得2个原核期受精卵和1个桑椹胚。
