INFLUENCE OF FAT CONTENT AND PRESERVATIVES ON THE BEHAVIOR OF LISTERIA MONOCYTOGENES IN BEAKER SAUSAGE

Behavior of Listeria monocytogenes Scott A in pork liver sausage containing 22–67% fat, and antilisterial activities of sodium lactate, sorbic acid, potassium sorbate and sodium propionate were studied during storage at 4C and 10C. Commercial pork liver sausage batter (22% fat), alone and with additions of lard (15, 30, and 45% by weight) were tested. Concentrations of 1.8% sodium lactate, 0.1% sorbate as the acid or the potassium salt, and 0.2% sodium propionate were tested in heat sterilized sausage inoculated with a 24 h culture of the organism (10⁴ CFU/g). Fat content alone caused small reductions in cell numbers by the end of the storage periods: from log CFU/g of 9.9 to 9.4 after 14 days at 10C, and from 7.3 to 6.5 after 50 days at 4C in the basic sausage formulation and with 45% added fat, respectively. The inhibitory activities of lactate and propionate increased with increase in fat content, and were more pronounced at 4C, where the effects were listericidal. Inhibition by sorbic acid was least influenced by the fat content, and the potassium salt was less antilisterial than the acid.

室温磁制冷材料La（Fe0.94Co0.06）11.7Si1.3在去离子水中腐蚀行为的研究木

针对La（Fe0.94Co0.06）11.7Si1.3磁制冷材料在去离子水中的腐蚀行为进行了研究，结果表明，腐蚀速率随时间的变化而变化，开始时腐蚀速率较快，随着时间的延长，腐蚀速率逐渐变慢。XPS能谱分析表明，腐蚀产物主要由γ-Fe2O3、Co（OH）2及H2SiO3组成，产物形态较为疏松，不足以对基体形成有效保护。腐蚀产物中没有发现La的信息，其具体原因有待在后续工作中进一步深入探讨。

关于防止海水入侵大小凌河扇地的研究

大、小凌河扇地与海水相连,扇地内地下水(淡水)与海水相接的界面,由于大量开采地下水,发生"采补"失衡的结果,平均以10～30 m/a的速度向内地入侵.目前已经影响锦州城市水源地和当地农民生产、生活的取水安全.结合本地区的实际情况,确定防止海水入侵的主要措施.该措施的特点是利用地表水,补给地下水,增加含水层内地下水压力,顶住海水入侵.这种以水治水的办法比砼防渗墙的阻咸措施降低工程造价70%～90%,这是一种节约建设资金、保证阻咸效果的最佳措施.

High-level synthesis design flow for power side-channel security

The lack of efficient security guidance is a prominent problem in the design flow of high-level synthesis. To tackle this issue, this paper proposes a security-based high-level synthesis design flow featuring the power side-channel vulnerabilities. The side-channel leakage is quantified by establishing a secure component module library, a more efficient and secure parallel scheduling mechanism is generated by optimizing the control flow, and a more secure architecture of the storage system is achieved by optimizing the data flow. The goal is to perform tradeoffs between performance and security, reducing the side-channel risks at the early stage of design and simultaneously generating more secure and efficient cryptographic cores in hardware. Furthermore, the proposed HLS design flow is verified on a field programmable gate array platform. Experimental results show that, in comparison with the traditional design flow, this method reduces the resources by 72% and the clock cycles by 70% and increases the throughput by 88%, and that it can lower the power side-channel risks within an ongoing design to the greatest extent.
