Popping视觉效果运用于表达角色心理活动刍议

Popping诞生于20世纪70年代左右,属于街舞的一个分支。舞者们常常将其他一些舞蹈元素融合进来,最终形成了我们现在所看到的多元化的舞蹈形态。这些被融合进来的舞蹈元素在视觉效果上各有特点,不光能停留在炫技这个相对外在的层面,还可以运用得更深、更广。通过对融合Popping相关元素用于表达相对复杂、抽象、内在的角色心理活动的探讨,为丰富Popping的内涵和外延,拓展舞蹈表达的边界,为建立一种新的舞蹈分支提供一种思路。

Identification of QTL for Popping Characteristics Using a BC_2F_2 Population and Comparison with Its F_(2:3) Population in Popcorn

Normal corn germplasm can be used to improve popcorn （Zea mays L.） through 1-2 backcrosses with popcorn as recurrent parents. Popping characteristics of derived lines from popcorn × dent or flint corn crosses play a determinant role in popcorn breeding. Advanced backcross QTL methods can effectively combine QTL identification and plant breeding. 220 selected BC2F2 families developed from a cross between Dan 232, a dent corn inbred line, and N04, an elite popcorn inbred line, were evaluated for three popping characteristics, popping volume, flake size, and popping rate, under two environmental conditions. Using composite interval mapping, a total of 10 significant QTLs were detected, and of these, 2 to 4 QTLs were identified for each trait. Six QTLs had favorable alleles contributed by Dan 232. Comparison with the 15 QTLs detected in the F2：3 families showed that 3 QTLs were the same in both populations. The QTLs should be redetected in generations developed through severe selection. Improved N04 and near isogenic lines could be developed from this BC2F2 population through selfing or another 1 to 2 backcrosses with N04.

Effectiveness of impedance monitoring during radiofrequency ablation for predicting popping

AIM： To retrospectively evaluate the effectiveness of impedance monitoring for predicting popping during radiofrequency ablation （RFA） using internally cooled electrodes. METHODS： We reviewed 140 patients （94 males, 46 females; age range 73.0 ＋ 11.1 year） who underwent RFA between February 2006 and November 2008 with a modified protocol using a limited power delivery rather than a conventional one to avoid popping. All the patients provided their written informed consent, and the study was approved by the institutional review board. Intraprocedural impedances were measured for the study subjects, and the tumors were classified into three types according to the characteristics of their impedance curves： increasing, flat, or decreasing. The tumors were further sorted into seven subtypes （A-G） depending on the curvature of the impedance curve＇ s increase or decrease. Relative popping rates were determined for the three types and seven subtypes. A chi-square test was performed to estimate statistical significance.RESULTS： A total of 148 nodules treated by RFA were analyzed. The study samples included 132 nodules of hepatocellular carcinoma, 14 nodules of metastatic liver cancer, and two nodules of intrahepatic cholangio- carcinoma. The numbers of nodules with each imped- ance curve type were as follows： 37 increasing-type nodules, 43 fiat-type nodules, and 68 decreasing-type nodules. Popping occurrence rates were 24.3%, 46.5% and 64.7%, respectively. Flat-type nodules exhibited a significantly higher rate of popping compared to increasing-type nodules （P = 0.039）. Decreasing-type nodules exhibited a significantly higher rate of popping compared to increasing-type nodules （P 〈 0.0001）. No- tably, nodules that showed a sharp decrease in imped- ance in the latter ablation period （subtype E） exhibited a significantly higher rate of popping compared to other subtypes. CONCLUSION： Intraprocedural impedance monitoring can be a useful tool to predict the occurrence of pop- ping during liver tumor RFA performed with internally cooled electrodes.

Protein Quality of Amaranth Grains Cultivated in Ethiopia as Affected by Popping and Fermentation

The effect of popping and fermentation on protein quality of three different varieties of amaranth grains cultivated in Ethiopia was evaluated. Total lysine content of the grains was higher than that of commonly available cereals but close to that of legumes. Methionine and cysteine contents in the grains were also higher than that found in cereal and legume proteins. Percentage of total indispensable amino acids, excluding tryptophan, was 43% - 49%, which was higher than WHO reference pattern (31%). Popping resulted in 36% and 37% reduction in total lysine and cysteine contents, respectively, whereas fermentation reduced cysteine, lysine and methionine contents by 16%, 20% and 20%, respectively. From the free amino acids, histidine was the major indispensable amino acid but threonine was not detected. During popping, all free amino acids, except threonine, were reduced. On the other hand, fermentation significantly increased (p < 0.01) most amino acids except arginine, which was significantly decreased (p < 0.01), and tyrosine and glutamic acid, for which no change was observed. Popping decreased in vitro protein digestibility (IVPD) by 8.3% - 17.1% while fermentation increased IVPD by 4.8% - 7.5%. Substitution of amaranth for wheat and/or maize during complementary food formulation could contribute much to the daily requirements of indispensable amino acids of young children.

东海近岸持久性有机污染物分布及其影响因素

收集分析近10a东海近岸海水和沉积物中全氟烷基物(PFASs)、多氯联苯(PCBs)、多溴联苯醚(PBDEs)、有机氯农药(OCPs)、邻苯二甲酸酯(PAEs)和多环芳烃(PAHs)等六种典型持久性有机污染物(POPs)的分布及其影响因素的研究数据.结果表明,基于半数效应浓度(EC50)或海洋沉积物质量标准对海水和沉积物中POPs的生态风险评估,表明东海近岸大部分海域的PCBs、PBDEs和OCPs生态风险较低,但在杭州湾附近海域处于轻微至中等生态风险水平.PAHs整体上处于中等偏低及以下风险,PAEs处于中等偏高风险.PFASs处于中等及以下风险,但其中的全氟辛烷磺酸(PFOS)在长江口附近的生态风险较高.来自陆源输入的POPs在东海近岸海水和沉积物中的分布主要受到长江冲淡水、大气干湿沉降、沿岸流和潮汐作用的影响,呈现出绝大多数污染物含量在长江口和杭州湾附近较高,且向外海和南部沿岸总体降低的趋势.在浙闽沿岸泥质区、东海陆架泥质区,沉积物中部分污染物含量明显较高,与泥质区细颗粒泥沙对POPs的结合能力较强密切相关.长江冲淡水与东海海水交汇过程中温盐差异形成的“大陆边缘过滤器”效应,使得沉积物中部分POPs含量在盐度1~5的海域较高.东海的季节性低氧使得DDTs和PCBs等POPs普遍发生还原降解作用.除生物降解作用之外,生物泵和生物扰动等也会影响POPs在东海的分布.虽然我国已加强了对POPs的管控,但目前东海近岸的局部海域的POPs污染仍然存在,有待未来进一步完善POPs的监测手段和风险评价标准,并继续加强对新污染物的监测和环境行为研究.

持久性有机污染物在危险废物鉴别中的限值修订建议

持久性有机污染物(POPs)已频繁在多种环境介质和人体组织中检出并受到环境研究者的重点关注。固体废物是POPs重要的源和汇,科学合理地处置含POPs固体废物对于遏制和减少该类污染物的环境危害具有重要意义。随着《关于持久性有机污染物的斯德哥尔摩公约》清单的更新,我国现行的GB 5085.6—2007《危险废物鉴别标准毒性物质含量鉴别》也需要及时修订完善。针对这一需求,对比了国内外含POPs固体废物的管理限值要求,梳理了我国典型固体废物或固体样品中POPs的残留现状。结果显示,大多数固体废物、环境样品或生物体中POPs含量在十亿分之一到百万分之一的水平,一些POPs在用途较大的样品中接近或可达千分之一的水平。其中,固体废物中POPs可能高于限值风险的种类有多溴联苯醚类、五氯酚和短链氯化石蜡等。结合我国现行危险废物鉴别标准制定的方法学,综合考虑技术可行性和社会经济影响等方面的因素,给出了我国《重点管控新污染物清单(2023年版)》中列举的19种(类)POPs在毒性物质含量鉴别中的建议修订限值。

东平湖水源地POPs的健康风险评价初探

为了揭示东平湖水源地持久性有机污染物(POPS)的健康风险水平,于2015年7月对东平湖16个不同点位的表层沉积物进行采样,并用GC-μECD仪器测定了有机氯农药(OCPs)、多氯联苯(PCBs)和多环芳烃(PAHs)含量,运用美国环保局(USEPA)推荐的健康风险评价模型开展健康风险评价。结果显示,东平湖水源地沉积物中OCPs将会对人体产生致癌危险,PCBs对人体可能产生潜在的健康危害,PAHs不会对人体造成致癌危害;OCPs非致癌风险指数较大,导致慢性非致癌健康的风险较高;PCBs仅有(I点)、(L点)会对儿童产生非致癌风险。

Snapshot Survey of the Presence of Perfluoroalkyl Substances in Products, Articles, and the Environment in Ecuador

The Stockholm Convention on Persistent Organic Pollutants(POPs)is a legally binding instrument for 186 Parties(status:April 2023).Accordingly,among other responsibilities,countries are obliged to report the production,import,or export of the POPs listed in Annexes A,B,or C;provide information to registers;maintain inventories;and monitor the presence of POPs in the environment.In the broader context of international chemicals and waste management,producer responsibilities,harmonized reporting,and compliance with national and international regulations,Ecuador has addressed the newly listed group of perfluorinated alkyl substances(PFAS)in its national implementation plan and sent selected products from its national market for PFAS analysis.The products analyzed came from the initially listed fields of specific exemptions and acceptable purposes,including:fire-fighting foams;photographic aids;greasers/degreasers;various kinds of paper/packaging;textiles;and leather,coatings,cleaners,metal plating,and pesticides.Our results showed that the three PFAS presently listed in the Stockholm Convention could be quantified in only a few samples;additional PFAS,not yet listed in the Convention also had low detection frequencies.Although the number of samples was limited,the samples covered a large spectrum of sample matrices,making it possible to conclude that—once these products become waste and are regulated under the Basel Convention—they would not constitute a disposal problem.Nevertheless,verification of the presence of PFAS in products on the market is expected to pose an analytical challenge for both,developed and developing countries.
