磷酸缓冲液预处理对高温胁迫下油菜叶片膜脂过氧化及体内保护系统的影响

高温胁迫下,油菜叶片细胞膜相对透性、丙二醛（MDA）含量和过氧化物酶（POD）活性增加;抗坏血酸（ASA）、谷胱甘肽（GSH）、可溶性蛋白质总量及热稳定性蛋白质所占比例与超氧化物歧化酶（SOD）和过氧化氢酶（CAT）活性下降;酸缓冲液预处理可维持较高的保护酶活性、抗氧化物质含量和较低的膜脂过氧化水平．     

基于IREQ模型的低温环境应急救援人员冷应激分析

为更准确地评估低温环境下应急救援人员冷应激情况,避免低温伤害。基于国家推荐性标准GB/T 24254—2009确定我国低温冰冻灾害应急救援作业工作服装热阻（IREQ）,并引入适合描述我国低温冰冻灾害高强度应急救援作业的人体储热率参数,对所需IREQ模型进行改进。计算分析低温冰冻灾害环境下应急救援人员的修正服装热阻、有限持续暴露时间、体温恢复时间。研究结果表明:改进的 IREQ模型计算所得的基本需求热阻更高,有限持续暴露时间更低,对提高低温环境下的应急救援作业安全性具有一定的科学意义。

介绍了几种不同组合的防护装饰性镀层经16年大气曝露试验后的情况。结果表明：具有约40μm厚度的多层镍 微孔铬或微裂纹铬组合镀层可以有效地保护钢铁基体在亚热带气候条件下免遭腐蚀：而厚度达60μm的普通铜 镍 铬、镍 铬组合镀层对钢铁基体不能提供可靠的腐蚀保护。     

Parental awareness and perception for correct use of child restraint systems and airbags in Brazil

Objective: The objective of this study was to obtain information about the current knowledge and habits of parents who transport children in cars in Brazil.

Methods: A cross-sectional survey was conducted using specifically designed self-report questionnaires to parents of children attending a private pediatric office in a town in southwest Brazil. Data were collected regarding children's age, gender, height, and weight and possession of an automobile child restraint system (CRS), its type, frequency and adequacy of use, and reasons for not possessing or not using the devices. Parents were asked whether their cars were equipped with airbags and about the use of the restraints in seats with airbags.

Results: We interviewed parents of 293 children transported in cars who met the criteria for use of a CRS. Children were younger than 1 year in 15.3% of the cases, between 1 and 4 years in 38.6%, and older than 4 in 46.1%. Cars were equipped with CRS in 78.5% of the cases, but in only 58% of the cases was the device proper for child's age and adequately installed in the seat. Among owners of the devices, 84.3% reported that they always used it. Reasons for infrequency were forgetting the device at home or in another car (6.4%), the child disliking the device (3.2%), or the false impression that the child was grown enough not to use it (3.2%)l 87.1% did not justify why they did not always use the CRS. Considering type of CRS, correct installation of the seat, and frequency of use, only 44.4% of children under 1 year, 69.9% of those 1 to 4 years, and 52.6% over age 4 were protected. Only 28.6% of the parents knew that children should never be positioned in a seat with active airbags.

Conclusion: Considering appropriateness for age, correctness of installation (in the back seat in the correct orientation), and frequency of use, only 50.85% (149/293) of the children were reported as always protected with a CRS. Children between 1 and 4 years were more likely to always use a CRS in this Brazilian survey. We were also able to identify an important gap in the knowledge about airbags among parents. Further efforts are needed to correct those distortions.
