The current paper deals with the evaluation of the BANCS erosion prediction model and its two componentsethe Bank Erosion Hazard Index（BEHI） and Near-Bank Stress（NBS） indices. To construct the erosion prediction curves, 18 experimental sections were established on the Kubrica Stream, district of Trencín, Slovakia. Each section was assessed through the NBS index and BEHI index and real annual bank erosion was measured using erosion toe pins. Subsequently, the relations between the BEHI and real annual bank erosion was assessed through regression and correlation analyses. The relation proved to be moderately strong, with the correlation coefficient（R） reaching 0.47. Further, the relation between the NBS index and real annual bank erosion was evaluated, which was also moderately strong, with R= *** on the measured data, two erosion prediction curves were constructed, the first for moderate BEHI, with R= 0.69 and coefficient of determination（R2） of 0.47 and the second for high BEHI with R=0.74 and R2= 0.55. The prediction curves were based on data from one year of measurements and can, therefore, be used only for discharges that occurred within that year and in the region where the model was developed. In the current case, according to runoff Curve Numbers（CN）, the real culmination discharge was Q ? 1.88 m3/s, which is roughly equivalent to 1.5-year recurrence interval flow（Q1.5）.

BACKGROUND AND OBJECTIVE In 2004, the World Health Organization highlighted the need to assess the effect of older age on recovery from mild traumatic brain injury (mTBI). This study was designed to determine whether, similar to younger adults, psychosocial markers would be identified as having prognostic value for older adults with *** Participants included adults, 65 years of age or older, presenting to the emergency room (ER) for mTBI within 72 hours of injury. The patients were contacted by phone within 10 days of the ER visit and asked to complete a computer-assisted telephone survey. The survey included sociodemographic, psychological and mental health factors, preinjury functional status and brain health, injury related factors and previous brain injuries. Six months after the ER visits, subjects were asked to complete several recovery outcome measures including post-concussion symptoms (PCSs), Glasgow Outcome Scale-Extended Version, the SF-12 and self-assessment of *** Subjects were 97 adults with a mean age of 76.2 years. The only baseline factor independently associated with all measures of recovery was worse health in the one year prior to injury. At six months, those reporting fatigue at the initial follow-up were four times more likely to report a poor recovery. Poor self-prognosis and baseline depression were associated with poor recovery but did not reach statistical *** This study of elderly individuals with a mild traumatic brain injury, found that worse recovery at six months occurred among those reporting worse health one year before injury, poor self-expectations for recovery, depression and fatigue shortly after injury.

In this study, advanced techniques such as atom probe tomography, atomic force microscopy, X-ray photoelectron spectroscopy, and electrochemical impedance spectroscopy were used to determine the corrosion mechanism of the as-ECAPed Zn-0.8mg-0.2Sr alloy. The influence of microstructural and surface features on the corrosion mechanism was investigated. Despite its significance, the surface composition before exposure is often neglected by the scientific community. The analyses revealed the formation of thin ZnO, mgO, and mgCO3 layers on the surface of the material before exposure. These layers participated in the formation of corrosion products, leading to the predominant occurrence of hydrozincite. In addition, the layers possessed different resistance to the environment, resulting in localized corrosion attacks. The segregation of mg on the Zn grain boundaries with lower potential compared with the Zn-matrix was revealed by atom probe tomography and atomic force microscopy. The degradation process was initiated by the activity of micro-galvanic cells, specifically Zn - mg2Zn11/SrZn13. This process led to the activity of the crevice corrosion mechanism and subsequent attack to a depth of 250 μm. The corrosion rate of the alloy determined by the weight loss method was 0.36 mm⋅a􀀀 1. Based on this detailed study, the degradation mechanism of the Zn-0.8mg-0.2Sr alloy is proposed.

分离到了不产生含铁超氧物歧化酶FeSOD(sodB)和过氧化氢酶阴性(katFG)的福氏志贺氏5型突变株。根据小鼠腹腔巨噬细胞和人多形核白细胞的杀死效应测定和家兔迥肠袢感染试验的结果表明其对氧压的敏感性有所增高。sodB对吞噬细胞的杀死作用比起其亲代野生株m9OT十分的敏感。过氧化氢酶阴性株虽然对这种杀死作用的敏感性也增高了,但在程度上小得多。家兔回肠袢的感染和此后的组织病理学检查方面,sodB突变株引起的肠绒毛损伤几乎检测不出,其感染作用的结果基本上类似于m9OT的无质粒无毒衍生株BS176,而katFG突变株则类似于m9OT,有很高程度的破坏作用。上述提示sodB编码的超氧物歧化酶在福氏志贺氏菌的致病性中可能有重要的作用,相比之下,过氧化氢酶的作用看来是有限的。
