AN EXAMINATION OF RETAIL CLIENTS＇ INVESTOR SUITABILITY RULES IN THE cobs AND THE LESSONS FOR CHINA

Frontiers of Law in China-Selected Publications from Chinese Universities 2018年第2期13卷 260-290页

作者： ZHENG Weiwei DING Yu Jilin University of China Changchun China Renmin University of China Beijing China Renmin University of China Beijing 100872 China

Nowadays, the complexity of financial products makes it difficult for retail clients to identify investment risks, and there is an increasing tendency for firms, stipulated by the maximum profits, to recommend or enter into unsuitable transactions to or for retail clients while providing services of investment advice and portfolio management, which causes great losses to a significant number of investors. So, in the contemporary society, the investor suitability rules through which retail clients can purchase suitable financial products are the indispensable legal basis of investor protection. Currently, the regulations concerning investor suitability management in China have several problems, including the chaotic legal system, low effectiveness level and defective contents, which may make it difficult for suitability to be applied in justice and managed effectively. Since the UK＇s investor suitability rules in the Conduct of Business Sourcebook that apply to retail clients whose contents include requirements of obtaining retail clients＇ information, requirements of information to be provided to retail clients and criteria of assessing suitability are clear and comprehensive, the authors believe that the UK＇s experiences can provide a great enlightenment for China to better investor suitability management rules, including integrating legal documents and optimizing effectiveness level, rationalizing application scope, adding criteria of assessing suitability and revising specific clauses.

Binding Ability of Corn cobs Hemicellulose toward Cadmium

引用

American Journal of Analytical Chemistry 2013年第7期4卷 86-93页

Non-Starch Polysaccahride (NSP) is an agricultural byproduct containing of cellulose, hemicelluloses, and lignin. Hemicellulose has a hydroxyl functional group and carboxylic function on the monomer hemicellulose used as a binding ability for cadmium ion and hence as a pharmaceutical active ingredient to prevent cadmium toxicity. The purpose of this study is to isolate and evaluate hemicelluloses from corn cobs as a binding ability toward cadmium ion. The study is conducted by isolating the corn cobs in such way using 0.2 M NaOH, characterization of hemicellulose from corn cobs produced by Infra Red Spectrofotometry. Binding ability of corn cobs hemicellulose (CCH) was done in 3 ways. The first, it was by titrimetric with cadmium 3 mg/cm3 as a titrant and indicator of 0.05 N NaOH. The second, it was by in vitro test at pH 2 as a comparison to use pectin. The third, the in vivo test was conducted in 3 variations of treatment covering CCH 10 mg, 100 mcg of cadmium for 10 weeks. Assay of cadmium was conducted using atomic absorption spectrophotometry with flame at a wavelength of 228.8 nm. The research result showed that the highest yield of hemicellulose (12.04%) was obtained from delignication with 0.03 M NaOH in 60% ethanol and 3% H2O2, hemicellulose isolation with 500 cm3 of 0.2 M NaOH, and precipitation with 1:4 ratio of 10% acetic acid in 95% ethanol. Characteristics of CCH on infrared vibration methods provide vibrational hemicellulose in the region of 1820-1600 cm-1. It meant that the functional group carbonyl was present, and the vibration widened near 3400-2400 cm-1. It indicated that there was the functional group vibration region of hydroxyl. It also meant that there was carboxylic group and finger print at 1500-500 cm-1. Test results of the titrimetric holding ability showed that CCH was binding 100 mg of cadmium (46.17 ± 0.9256) mg or 46.17%. Binding ability test results at pH 2 showed that 300 mg of CCH yield was binding 30 mg cadmium of (26.68 ± 0.1490) mg or 88.93%. The results of in vivo tests show

Relationship between Physico-Mechanical Properties, Compacting Pressure and Mixing Proportion of Briquettes Produced from Maize cobs and Sawdust

引用

Journal of Sustainable Bioenergy Systems 2014年第1期4卷 50-60页

作者： Stephen J. Mitchual Kwasi Frimpong-Mensah Nicholas A. Darkwa Department of Construction and Wood Technology Education University of Education Winneba Kumasi Campus Kumasi Ghana Department of Wood Science and Technology Kwame Nkrumah University of Science and Technology Kumasi Ghana

This study examined the relationship between selected physico-mechanical properties, compacting pressure and mixing proportion of briquettes produced from combination of maize cob particles and sawdust of low, medium and high density timber species. Particle sizes of maize cobs and sawdust used for the study were ≤1 mm. The two materials were combined at mixing percentages of 90:10, 70:30 and 50:50 (Sawdust:maize cobs). Briquettes were produced at room temperature (28°C) using compacting pressures 20, 30, 40 and 50 MPa. The results suggested that combining maize cob particles with sawdust of low, medium and high density wood species could significantly enhance the relaxed density, compressive strength in cleft and impact resistance index of briquettes produced from agricultural biomass residue like maize cobs. The results further indicated that the physical and mechanical characteristics of briquettes produced from combinations of sawdust of low density species and maize cobs were exceptionally higher than that produced from combinations of maize cob particles, and medium density and high density timber species. The R2 values for the regression model between the independent variables (mixing percentage and compacting pressure) and relaxed density, compressive strength in cleft and impact resistance index of briquettes produced from combinations of maize cob particles and sawdust of low density species (Ceiba pentandra) were 0.966, 0.932 and 0.710 respectively. This study provides a hope for briquetting maize cobs at room temperature using a low compacting pressure.

COBAS MIRA系列全自动生化分析仪是由瑞士 Roche公司生产的一种准确性和重复性都较好的生化分析仪，但其零配件较为昂贵。在使用 COBAS MIRAS和 COBAS MIRA PIUS两种型号的生化分析仪十来年的过程中，摸索出部分零配件可以修旧利废和用国产件替代，现介绍几例如下。故障 1 冲洗塔溢水。故障分析与检修首先应检查冲洗塔至废液泵管道和其间的过滤器是否通畅，如管道和过滤器阻塞，应做相应的疏通处理。过滤器有两种，一种为陶瓷滤芯过滤器，虽易堵塞但可用酸洗液浸泡，蒸馏水反复冲洗后重复使用。另一种为滤膜过滤器，虽使用时间较长，但时间过久滤膜可腐烂而堵塞管道，应适时更换新的过滤器。管道与过滤器未出现上述问题，则应检查废液泵是否正常工作。废液泵开始出现故障时，通常时好时坏，只要做相应的清洗保养，即可恢复正常工作。一旦损坏到不可修复，则要更换废液泵。而一只废液泵价值人民币两万余元，价格不菲。我们采用其他报废机器的废液泵替代，至今正常工作已两年有余。具体做法是采用美国 Ciba Coning公司出品的 SBA－ 300型全自动生分分析仪外置的 GILFORD vacuum recelver3021真空泵，选用适合的硅胶管与生化仪内甩开废液泵后的相应管道相连接，将压力调至－ 2mmHg＊内即可，切不可过高以免负压过大。当然选用手头拥有的其他负压适合的真空泵也可。
