稀土Sm掺杂PLA／TiO2杂化材料的制备及抗凝血性能测定

以乳酸为原料、辛酸亚锡为催化剂制备聚乳酸（PLA）;以PI。A、Sm、钛酸四正丁酯（TBT）为原料,采用溶胶凝胶法制备稀土Sm掺杂PLA／TiO2有机无机杂化材料。XPS分析结果显示了Sm的加入。动态凝血时间测定法测定结果表明。Sm的掺杂提高了PLA／TiO2的抗凝血能力,并且在加入量为wt0．6％时效果最佳。     

Implementation of advanced peripheral bus interface for MV1O MCU

MV10 is an MCU which consists of PWM,ADC,CAN and some other function blocks.It is designed for car body's control.Advanced peripheral bus (APB) is a low speed AMBA bus connecting low-power peripherals.This paper presents an implementation of APB interface for MV10 MCU.After that,MV10 can be integrated into any AMBA system on chips (SoCs) easily.We have built a multi-core system with ABMA to verify this design.In this system ARM9 is a main processor mounted on AHB and MV10 acts as a low-power and low-speed slaver on APB.Before building this system,some operations are encapsulated into a task with dedicated ID.MV10 works as a co-processor with ARM by acquiring task ID from ARM.The result of simulation indicates that MCU can work well as expected.Based on our design,MV10 can be mounted on any AMBA system from now on.

Immigration and student achievement: Evidence from Switzerland

This paper investigates empirically whether immigrant students in Switzerland perform poorly compared to their native counterparts and provides some explanations. Using a national sample of the 2000 PISA (Programme for International Student Assessment) database, we first analyze the impact of immigrant status on pupils’ achievement. We find a negative and significant impact of immigrant status on test scores in reading, mathematics and science literacy, even after controlling for a set of characteristics. We then decompose the observed reading score gap between Swiss and immigrant students to identify whether gaps in endowments explain test score differences along the distribution. Lower endowments explain most of the achievement gap in reading between Swiss and second-generation immigrants. However, lower returns explain around one quarter of the achievement gap between Swiss and first-generation immigrants for the weakest pupils.
