| 1 | 紫外光照对铝鞣胶原基材料的影响显示文摘为了研究紫外光照对铝鞣胶原基材料的影响,利用耐候仪对铝鞣胶原基材料在50℃、辐射量0.35W/m2下分别老化0、24、48和72h,以加速其在紫外照射条件下的老化速度。利用扫描电镜(SEM)研究老化前后铝鞣胶原基材料纤维形貌的变化;利用显微收缩温度仪(MHT)、差示量热扫描仪(DSC)和热重分析仪(TG),研究老化前后铝鞣胶原基材料的热学性能。试验结果表明:随着紫外照射时间的延长,铝鞣胶原基材料纤维编织变得松散、纤维间隙增大、部分纤维链断裂,热稳定性和耐热降解能力均出现降低,说明紫外光照射对铝鞣胶原基材料的结构和性能产生了破坏,且紫外照射时间越长,破坏作用越明显。 | 高艳平 杨爽 张金伟 Lucretia Miu 陈武勇 | 2015 | 中国皮革2015，44，16： | 2 |

| 3 | 羊皮纸现代复制工艺显示文摘在传统羊皮纸制作工艺基础上,增加软化和浸酸工序,制得现代羊皮纸。通过组织学观察,研究了浸灰时间对纤维的分散和非纤维成分的去除。测定了所制羊皮纸的拉伸强度(MPa)和撕裂强度(N/mm),其值分别为:10.24,18.72;色度色差仪测定了皮的表面颜色,其亮度值分布在85~90,说明其表面颜色较白;视频接触角测量仪测试了羊皮纸的接触角,其值大于90o,说明所制羊皮纸具有较好的疏水性。研究结果表明羊皮纸复制工艺基本可行。 | 杨爽 龚英 陈武勇 Lucretia Miu | 2012 | 皮革科学与工程2012，22，4： | 1 |

| 5 | Production and Evaluation of Table Wine Using Two Different Varieties of Pawpaw (Carica papaya)显示文摘The aim of this study was to produce and evaluate table wine from two different varieties of pawpaw (rose red and yellow pawpaw). The must was evaluated for physicochemical and microbiological changes during fermentation while the wine was analyzed for physicochemical characteristics, microbiological quality and sensory properties and compared with commercial grape wine. Specific gravity of the “must” during fermentation decreased from 1.059-0.995 for rose red pawpaw and 1.005-0.990 for yellow pawpaw. The sugar content decreased from 13-3% on the 14th day of fermentation for rose red pawpaw while yellow pawpaw “must” decreased from 12.5-3%. pH drop for the yellow pawpaw “must” was 4.7-3.4 on the 14th day and 4.0-3.4 for rose red pawpaw “must”. Titratable acidity of the pawpaw “must” increased from 0.16-0.32% for rose red pawpaw “must” and 0.20-0.52% for yellow pawpaw “must”. Microbial analysis of the “must” during fermentation showed that yeast count increased from no growth to 3.0 × 10^6 cfu/mL for yellow pawpaw must and 4.0 × 10^6 cfu/mL for rose red pawpaw, respectively while total bacterial count decreased from 5.4 × 10^7-l.5 × 10^7 cfu/mL for yellow pawpaw must and 5.2 × 10^7-1.2 × 10^7 cfu/mL for rose red pawpaw “must”. Coliform recorded no growth throughout the period of fermentation. Physicochemical analysis of the wine showed that the yellow pawpaw wine has a specific gravity of 0.999, alcohol content 8.00%, titratable acidity of 0.59%, pH of 3.5 and sugar content of 3%. The rose red pawpaw wine had sugar content of 3%, titratable acidity of 0.38%, alcohol content 7.69%, specific gravity 0.997 and pH of 3.5. Microbial analysis of the wine showed no growth of coliform and yeast while bacterial count was 1.0 × 10^6 cfu/mL for both wines. Sensory results for the pawpaw wine showed no significant (p > 0.05) difference in the clarity and overall acceptability from the commercial wine. | David Barine Kiin-Kabari Queen Igbo Lucretia Ifeoma Barber | 2019 | Journal of Food Science and Engineering2019，9，6： | 0 |
| 6 | The Influence of an Alternative Laboratory Placement:Overcoming the Fear of Teaching Science显示文摘As preservice science and social studies faculty worked with a group of underserved and underrepresented students in a rural community in a southern state,this study looked at how to best prepare preservice teachers to teach science autonomously.More specifically,this study looked to address the expressed concerns of preservice elementary school teachers that they have as it relates to their comfort and understanding of how to teach science,particularly STEM-related labs,and activities,along with the day-to-day operations of classroom management and logistics.During this time and study,the preservice teachers were able to build their confidence and needed skill sets because they had total autonomy and control of their preparation,planning,execution,classroom management,classroom support services,and before and after class activities.The certified mentor teachers were present due to state requirements as well as being able to offer context,support,and reference to specific students and community perspectives.During this study,the author regularly observed and monitored the preservice teachers as they developed individually from expressing fears of not only teaching science for the first time,but also sharing their concerns for classroom management,and time management,as well as developing interpersonal relationships with new students.For some,they were able to learn not all experiences will be positive,there will be challenges and limitations,however,there is great satisfaction to be gained as they recognized that experience is the best teacher. | Lucretia Octavia Tripp | 2023 | US-China Education Review(B)2023，13，2： | 0 |
| 7 | 传奇·公路片·温暖《若水》显示文摘还没有过这样带着怀疑的心情来等黄耀明出碟的经验。一来内中部分歌曲早就开始在电台、电视台播放,听下来也并没太惊喜,再来看见唱片封套——美不美倒还其次,创意明显脱胎自比约克的《OCEANIA》,甚至连《若水》这么文艺腔的字眼,都让人疑心是'OCEANIA'的老庄版翻译。 | Lucretia | 2007 | 书城2007，，2： | 0 |
