Criteria for Selecting Carbon Subsurface and Ocean Storage Site in Developing Countries: A Review

引用

American Journal of Climate Change 2024年第2期13卷 103-139页

作者： gregory Mwenketishi Hadj Benkreira Nejat Rahmanian School of Engineering Faculty of Engineering and Digital Technologies University of Bradford Bradford UK

Important first phases in the process of implementing CO2 subsurface and ocean storage projects include selecting of best possible location(s) for CO2 storage, and site selection evaluation. Sites must fulfill a number of criteria that boil down to the following basics: they must be able to accept the desired volume of CO2 at the rate at which it is supplied from the CO2 source(s);they must as well be safe and reliable;and must comply with regulatory and other societal requirements. They also must have at least public acceptance and be based on sound financial analysis. Site geology;hydrogeological, pressure, and geothermal regimes;land features;location, climate, access, etc. can all be refined from these basic criteria. In addition to aiding in site selection, site characterization is essential for other purposes, such as foreseeing the fate and impacts of the injected CO2, and informing subsequent phases of site development, including design, permitting, operation, monitoring, and eventual abandonment. According to data from the IEA, in 2022, emissions from Africa and Asias emerging markets and developing economies, excluding Chinas, increased by 4.2%, which is equivalent to 206 million tonnes of CO2 and were higher than those from developed economies. Coal-fired power generation was responsible for more than half of the rise in emissions that were recorded in the region. The difficulty of achieving sustainable socio-economic progress in the developing countries is entwined with the work of reducing CO2 emissions, which is a demanding project for the economy. Organisations from developing countries, such as Bangladesh, Cameroon, India, and Nigeria, have formed partnerships with organisations in other countries for lessons learned and investment within the climate change arena. The basaltic rocks, coal seams, depleted oil and gas reservoirs, soils, deep saline aquifers, and sedimentary basins that developing countries (Bangladesh, Cameroon, India, and Nigeria etc.

This study investigated the impact of different ratios of soluble to insoluble dietary fiber(SDF:IDF)formulations by sugar beet pulp(SBP)supplementation on piglet growth performance,nutrient digestibility,immune function,intestinal morphology,intestinal microbiota and intestinal health.A total of 60 crossbred piglets(Duroc×[Landrace×Yorkshire])at 40 d old with body weight of 10.0±0.3 kg were randomly assigned to 5 treatments with 6 replicates per treatment and 2 piglets per replicate in a 21-d *** dietary treatments included a corn-soybean meal diet(0%SBP supplementation;CON),and diets supplemented with 2%,4%,6%,and 8%SBP,representing different SDF:IDF ratios at 10.16%,13.53%,16.79%,19.86%,and 24.81%,*** results indicated that the 8%SBP treatment had a negative effect on feed-to-gain ratio(linear,P=0.009)compared with the CON treatment(P=0.021).The apparent total tract digestibility(ATTD)of crude protein was lower in treatments supplemented with SBP(P=0.002)and showed a linear decrease(P=0.001),while the ATTD of IDF showed a linear increase(P=0.037)in four SBP treatments compared to the CON *** 4%SBP treatment increased serum concentrations of triglyceride(quadratic,P=0.019)and K(linear,P<0.0037),and decreased alanine transaminase concentration(quadratic,P=0.015)compared with the CON *** concentrations of Cit,Cys,Ile,Leu,Orn,Arg,taurine,urea,1-methylhistidine,α-aminoadipic acid,α-aminobutyric acid and cystathionine in the 4%SBP treatment were highest among all treatments(P<0.05).The serum concentrations of interleukin-6,interleukin-8,interleukin-10,transforming growth factor-β,and tumor necrosis factor-αin the 6%SBP treatment were higher than those in the CON treatment(P<0.05),which also increased mucin-2 and G protein-coupled receptor 41 mRNA expression(P<0.05)in colonic mucosa compared with the CON treatment and improved the intestinal barrier *** containing more than 19.86%SDF:IDF could impair the intestinal healt

磁星是一类具有强磁场和长自转周期的年轻中子星.这些天体极其致密,半径约为12 km,但质量却可达太阳的1~2倍.在已知的30颗磁星中,只有少数会偶尔产生射电辐射.磁星转动时,射电束像灯塔一样扫过天空,天文学家正是从这些规律的脉冲信号中探索中子星的奥秘. 2018年末,磁星XTE J1810-197在经历了X射线爆发后再次产生射电辐射,结束了其长达十年的射电静默期.通过长时间、高频次的监测,我们在射电偏振信号中发现射电束相对于地球的倾角发生了显著变化,并且这种变化在几个月内逐渐消失^([1]).我们认为这种变化是由磁星的自由进动引起的,并提出了衰减的进动模型来解释这一观测现象.这一发现不仅帮助我们更深入地理解了磁星的内部结构和辐射几何,而且很可能排除了自由进动作为重复快速射电暴起源的理论模型.

Heart failure with preserved ejection fraction(HFpEF)has an estimated incidence rate of approximately 27 cases per 10,000 person-year[1].Furthermore,the prevalence of HFpEF is on the rise and is expected to exceed that of heart failure with reduced ejection fraction(HFr EF)[2].In the near future,HFpEF is expected to become the predominant subtype of heart failure[2].

{111}/{111}近奇异晶界较比一般晶界更耐蚀,如何提高此类晶界比例以显著提高Al及其合金晶界腐蚀抗力是一个新课题。本工作选用99.99%(质量分数)高纯Al为研究对象,考察晶粒长大对{111}/{111}近奇异晶界的影响。样品经室温多向锻造和370℃再结晶退火后,再经500℃保温不同时间,采用基于EBSD和五参数分析的晶界界面匹配表征方法对样品进行测试和分析。结果表明,随着晶粒长大,{111}/{111}近奇异晶界的比例显著增加。当平均晶粒尺寸由38μm长大至77μm时,{111}/{111}近奇异晶界的比例由3.91%增加至6.56%。离线原位EBSD和晶界迹线分析表明,晶粒长大过程中,{111}/{111}近奇异晶界主要通过具有/θ(θ为取向差转角)取向差关系的两两晶粒吞并周边晶粒并相遇后形成;具有/θ取向差关系的相邻晶粒,其晶界通过再取向调整至{111}/{111}位置,亦可形成此类近奇异晶界。{111}/{111}近奇异晶界存在旋错结构,其原子排列有序度显著高于一般晶界,这是此类晶界比一般晶界更耐蚀的原因。

Vaginal Birth after Cesarean after Zavanelli Maneuver: A Woman’s Right to Choose

引用

Open Journal of Obstetrics and Gynecology 2024年第7期14卷 1091-1095页

作者： Nicole Jenkins gregory Vurture Jonathan D. Baum Department of Obstetrics and Gynecology Jersey Shore University Medical Center Neptune NJ USA

Introduction: Vaginal birth after cesarean (VBAC) plays an essential role in lowering cesarean rates. Despite endorsement, trial of labor after cesarean (TOLAC) attempt rates remain low, in part due to fear of lawsuits. Zavanelli maneuver is a last resort procedure in the management of shoulder dystocia. We discuss a case of a woman determined to have a vaginal birth after her prior birth was complicated by shoulder dystocia requiring a Zavanelli maneuver. Her physicians were reluctant to allow her a TOLAC given her prior obstetric history. Case: A 34-year-old para 1 with prior cesarean delivery due to shoulder dystocia that required Zavanelli maneuver presents determined to pursue VBAC in her current pregnancy. She considered her delivery route options and addressed her modifiable risk factors. She consulted with multiple perinatologists who agreed that a TOLAC was reasonable, however she had to travel more than 70 miles (from Pennsylvania to New Jersey) to find an obstetrical practice and hospital willing to consider VBAC. She transferred care and the remainder of her prenatal course was uncomplicated. She went into labor at 41 weeks and had a successful VBAC without complication. In a thank you letter to her obstetrician, she described her birth experience as euphoric. Conclusion: This case illustrates how a woman’s choice of delivery route may be impacted by fear of litigation. Local providers focused on her prior delivery instead of her overall improved risk profile. Delivery route decisions should be based on a thorough evaluation of all risk factors and individualized to meet the reproductive goals of each woman. .

提高{111}/{111}近奇异晶界比例可增强Al-Zn-Mg-Cu合金晶界腐蚀抗力,为了解此类晶界形成机理并探索其调控方法,本工作将470℃、12 h和520℃、6 h双级固溶及冷轧后再结晶的Al-Zn-Mg-Cu合金样品分别在450、480和520℃进行应变速率为0.001 s^(-1)、真应变为1.20的压缩变形,压缩后立即水冷。采用电子背散射衍射和基于五参数分析的晶界界面匹配定量表征方法对上述3个样品的显微组织和晶界特征分布进行观察分析。结果表明,高温压缩后的显微组织不均匀,存在间隔分明的细晶组织和粗晶组织,其中细晶组织中的晶界以小角度晶界(LAGB)为主,粗晶组织中的晶界以大角度晶界(HAGB)为主;粗、细晶组织中的{111}/{111}近奇异晶界({111}/{111}-NSB)比例均随压缩温度的升高而增大,其中经520℃压缩的试样,其LAGB中的{111}/{111}-NSB占总晶界的比例为8.77%,HAGB中的{111}/{111}-NSB占总晶界的比例为4.53%。进一步考察各试样的应力-应变曲线以及450℃压缩30%时的显微组织特征可见,应变介于0.05~0.70为稳态流变阶段,主要发生初次动态再结晶(DRX),其主要由粗晶及其HAGB构成。应变介于0.70~1.20为二次硬化阶段,主要发生二次DRX,其中不连续DRX(DDRX)和连续DRX(CDRX)同时进行,且优先发生在某些微区;不论是DDRX因形核和核心长大生成的HAGB,还是CDRX因亚晶合并引入的LAGB,均使对应微区的晶粒细化,导致样品总体流变应力急剧上升。二次DRX阶段,CDRX行为随压缩温度的提高而增强,{111}/{111}-NSB比例也随之增加,特别是LAGB中的{111}/{111}-NSB比例快速增加。

不同于低层错能面心立方结构的奥氏体不锈钢,高层错能体心立方结构的铁素体不锈钢在形变及再结晶等组织重构过程中很难形成结构稳定且十分耐蚀的奇异晶界(共格孪晶界).研究{011}/{011}近奇异晶界的影响因素和形成机理,将有可能为改善铁素体不锈钢,特别是低Cr铁素体不锈钢晶间腐蚀性能提供晶界工程新思路.本文选用经固溶处理和组织均匀化处理的00Cr12低Cr铁素体不锈钢为实验材料,5个平行试样分别在350℃,500℃,580℃,650℃和690℃进行厚度减缩量为70%的单向轧制变形后,立即进行750℃、2 h再结晶退火处理.使用基于电子背散射衍射和五参数分析的晶界界面匹配表征方法对上述样品进行测试和分析发现,轧制温度对00Cr12铁素体不锈钢再结晶{011}/{011}近奇异晶界比例有显著影响,再结晶后的{011}/{011}近奇异晶界比例随再结晶退火前轧制温度的升高先上升再下降,其中经650℃轧制的样品,其再结晶后{011}/{011}近奇异晶界比例达到极大值6.82%.取向分布函数(ODF)和重叠极图晶界迹线分析表明,经650℃轧制的样品,其再结晶组织中形成了强的{011}织构;具有{011}及其漫散取向的晶粒之间较多地存在/θ取向差关系(θ为绕的旋转角),其关联晶界为{011}/{011}近奇异晶界,这是经650℃轧制的样品,其再结晶后{011}/{011}近奇异晶界比例达到极大值的原因.离线原位表面侵蚀实验表明,{011}/{011}近奇异晶界的腐蚀抗力显著高于一般晶界.因此,基于本文研究结果,进一步调控并提高{011}/{011}近奇异晶界的比例将有助于从根本上显著改善00Cr12铁素体不锈钢晶间腐蚀性能.
