Surface inlets are installed in subsurface drainage systems to reduce ponding duration and surface runoff, but can contribute to water quality concerns by allowing water to directly enter buried drains. Blind inlets consist of perforated pipes covered with gravel and are separated from an overlying sand layer by a geotextile membrane and have been shown to be more effective in reducing losses of sediment, nutrients, and pesticides than typical tile line risers. In this study, we investigated whether the effectiveness of blind inlets to sorb pollutants, with emphasis on the herbicide atrazine, could be further improved by amended them with materials other than limestone. The media, shredded tires (tire chips), electric arc steel furnace slag (steel slag), and oak-derived biochar were chosen because they are readily available, inexpensive, and do not present environmental concerns. Kinetic sorption and isotherms were determined to ascertain atrazine sorption by these materials, in addition to testing for potential metal leaching using the Synthetic Precipitation Leaching Procedure (SPLP) and the Toxicity Characteristic Leaching Procedure (TCLP). The kinetic data were fitted using pseudo first- and second-order reaction equations and indicated that atrazine sorption rate was 38 times faster and equilibrium was reached 5 times earlier for biochar than tire chips. The 24-h sorption isotherm data were fitted to the Freundlich sorption equation. The sorption coefficient for biochar was higher than for tire chips, steel slag, and limestone. Per the SPLC and TLCP tests, there was no leaching of heavy metals at levels of environmental concern. Our results suggested that the effectiveness of blind inlets as well as other conservation practices that include filter media such as rain gardens and filter socks could be improved by incorporating more reactive materials than sand and gravel with biochar being a particularly effective alternative.

利用神舟8号飞船的SIMBOX发射机会,对真实微重力影响裸藻光合作用活性进行了研究.我们发现,微重力降低了光合活性(Fv/Fm),提高了细胞内叶绿素a和胡萝卜素含量.快速叶绿素荧光动力学研究显示微重力降低了叶绿素荧光强度,但快速叶绿素荧光动力学曲线的形状(O-J-I-P)没有改变.在微重力处理下裸藻的最大光化学效率(φPo)、用于电子传递的量子产额(φEo)和光合作用性能指数(PIABS and PICS)都明显降低,但单位反应中心吸收的光能(ABS/RC)和单位反应中心耗散的能量(DIo/RC)都明显升高.77K低温荧光光谱实现微重力改变了能量在PSⅠ和PSⅡ之间的分配并出现了红移现象.这些结果表明真实微重力降低光合作用的活性有可能通过两个途径,即抑制裸藻抑制光合电子传递中PSⅡ的受体端和改变PSⅠ的结构从而引起流向PSⅠ的能量传递减少.

全球碳循环研究计划强调两个基本问题。第一个是关于碳系统对人为扰动的直接响应,即化石燃烧和土地利用变化排放出的过多的CO_2如何分布在大气、陆地和海洋中,以及这种分布如何随时间而变化?第二个问题是反馈问题,即气候变化如何反过来影响自然界碳循环并导致大气CO_2浓度的变化?本文评述解决这些问题的观测约束条件:①记录最近100年来CO_2浓度增加的大气直接观测和冰芯测量;②用观察氧和碳同位素的新方法和模型模拟都得到当前大气CO_2的收支估值,在此估值中海洋的作用如何?③通过CO_2全球监测网揭示的空间分布信息。100年前Arrhenius与他的同事(地质学家Hogbom)都注意到了控制大气中CO_2浓度的主要过程,然而他们的兴趣在于长期特征而没有察觉工业排放对全球气候的直接威胁。今天,我们能够定量确定和模拟人为扰动的直接影响,尽管大量不确定因素依然存在,特别是在地球生物圈过程方面。然而,我们对许多碳循环气候反馈的理解还是很有限的,这个问题在未来几十年里将始终是一个具有挑战性的课题。

Objectives: Patients with ischemic ventricular arrhythmia (IVA) in the form of fibrillation or tachycardia represent a surgical challenge. Evidence in the literature suggests that ventricular arrhythmia threatens survival even after cardiac surgery. We aim to review the results of our patients presenting with IVA with regard to short and long term outcome following cardiac surgery. Methods: This was a retrospective study of data entered prospectively into our cardiac surgical database between January 1999 and September 2015. A total of 9609 patients underwent Cardiac Surgery which included 54 patients after surviving IVA. The short- and long-term outcomes were compared to a propensity matched group. Actuarial survival was calculated using Kaplan Meier analysis. Results: The 54 study group patients were propensity matched on a 1:2 basis with a control group of non-IVA (n = 108). The baseline preoperative characteristics and risk factors were similar between the 2 groups and all cases underwent CABG only. Univariate analysis showed pacing postoperatively (33.3 vs 66.7%;p = 0.001) and postoperative ventricular arrhythmia (10 vs 22.2%;p = 0.039) to be significantly higher in the IVA group. Cox-multivariate analysis showed postoperative ventricular arrhythmia in either group (Hazard ratio = 1.5) to be the only significant factor to impact mortality (p 0.001). Long term survival was not significantly different between the two groups (10.4;CI: 9.08 - 11.75 vs 9.3;CI: 7.61 - 11.01 yrs, p = 0.3). Conclusion: Cardiac surgery on patients presenting with IVA can be performed safely yielding short and long term results equivalent to non-IVA cases. These patients should not be denied surgery with consideration of good long term outcome.

Micropropagation from shoot tips and nodal segments was carried out for the conservation and domestication of spontaneous Moroccan thyme, Thymus broussonetii Boiss. subsp. broussonetii (endemic threatened). The mineral composition of the culture medium, as well as the succession of different growth regulators, influenced the in vitro growth of this species. Sterilized achenes of T. broussonetii were able to germinate on an agar medium containing Gautheret macronutrients with a rate of 25% and a degree of contamination of less than 4%. Shoot apices of 15-day seedlings (two cotyledon leaves) were cultivated on SD + 0.46 μM Kin medium and the explants obtained were transplanted every month. Six macronutrients (MS, B5, SH, SD, MSm and N30K) were tested and N30K was chosen for the following experiments. Seven cytokinins (Kin, BAP, 2iP, DPU, adenine, Zeat and TDZ) at 0.46, 0.93 and 2.32 μM/l were evaluated and the addition of 0.93 μM adenine to N30K medium favored significantly the induction of buds and the elongation of explants. Three polyamines (putrescine, spermidine and spermine) at 2, 5, 10 and 20 μM/l were tested. A better multip
