Electronic Reserves: A Centralized Approach to the Scanning Process     

《Journal of Interlibrary Loan, Document Delivery & Electronic Reserve》2013,23(3):105-112

ABSTRACT

Electronic reserves are being offered at colleges and Universities across the country creating an opportunity for collaboration between the library units of academic libraries. Library units with course reserves in medium and large academic libraries can capitalize on the benefits working with a centralized scanning unit, thus consolidating the scanning process of electronic reserves processing. The cooperation between library units to provide better service results in a positive relationship between course instructors, students, and the library.  相似文献   

An evaluation of personalised insoles developed using additive manufacturing     

Andre S. Salles  Diane E. Gyi 《Journal of sports sciences》2013,31(4):442-450

Abstract

The aim of the study was to evaluate the short and medium term use of personalised insoles, produced by combining additive manufacturing (AM) with three-dimensional (3-D) foot scanning and computer aided design (CAD) systems. For that, 38 runners (19 pairings) were recruited. The experimental conditions were: personalised and control. The personalised condition consisted of trainers fitted with personalised glove fit insoles manufactured using AM and using foot scans to match the plantar geometry of the feet. The control condition consisted of the same trainers fitted with insoles also manufactured using AM but using scans of the original insole shape. Participants were allocated to one of the experimental conditions and wore the trainers for 3 months. Over this period they attended three laboratory sessions (at months 0, 1.5 and 3) and completed an Activity Diary after each training session. The footwear was evaluated in terms of discomfort and biomechanics. Lower discomfort ratings were found in the heel area (P ≤ 0.05) and for overall fit (P ≤ 0.05), with the personalised insole. However, discomfort was reported under the arch region for both conditions. With regard to the biomechanical data, differences between conditions were detected for ankle dorsiflexion at footstrike (P ≤ 0.05), maximum ankle eversion (P ≤ 0.05) and peak mean pressure under the heel (P ≤ 0.01): the personalised condition had lower values which may reduce injury risk. The personalisation of the geometry of insoles through advances in AM together with 3-D scanning and CAD technologies can provide benefits and has potential.  相似文献   

Morphology of polyethylene ski base materials     

Jörg Fischer  Gernot M. Wallner  Alois Pieber 《Journal of sports sciences》2013,31(5):555-562

Abstract

We used high-resolution Raman spectroscopy and differential scanning calorimetry for a comprehensive analysis of carbon black-filled polyethylene ski base grades at processing stages from the raw material to the structured ski base. Based on Raman mapping, we assessed the applicability of an advanced evaluation procedure for amorphous, disordered, and crystalline phase fractions of polyethylene for polyethylene extrusion and sinter grades. For sinter grades, a sufficient segregation between carbon black and polyethylene was confirmed, allowing for a comprehensive Raman spectroscopic morphological analysis. Significant morphological changes in polyethylene due to processing from the raw material to the semi-finished film and to the structured ski base were identified. Throughout the processing chain, we observed a decrease in crystallinity and an increase in the amorphous phase fraction. Although the raw material and the sintered semi-finished film exhibited a different but uniform polyethylene morphology, the morphological changes due to structuring of the ski base are limited to the top surface layer. The highest amorphous phase fractions were detected in the surface of the structured ski bases.  相似文献   

利用STM研究苝四羧酸分子间的作用机制     

刘春华  李亿保  谢云志  李勋  范小林 《赣南师范学院学报》2013,(6):32-35

通过对苝-3,4,9,10-四羧酸二酐(PTCDA)酸化,合成了苝-3,4,9,10-四羧酸(PTCA),采用红外、氢谱等方法对目标产物进行了表征.并且采用荧光光谱研究了产物的光学性质,结果表明:酸化后的PTCA表现出很强的荧光特性.为了进一步揭示分子作用机制,以高定向热解石墨HOPG(Highly Oriented Pyrolytic Graphite)为基底,利用扫描隧道显微镜(STM)研究了PTCA分子在固-液界面的二维(2D)自组装行为,实验结果表明了分子间的作用力来源于分子间的氢键和π-π堆积相互作用力.  相似文献
