SUm.ARY Postpartum.psychosis is a condition characterised by rapid onset of psychotic sym.tom. several weeks after childbirth. Outside of its tim.ng and descriptions of psychotic features, m.nim.l research exists due to its relative rarity (1 to 2 per 1000 births in the USA), with greater em.hasis on postpartum.sadness and depression. With the existi叩 literature, cultural differences and language barriers previously have not been taken into consideration as there are no docum.nted cases of postpartum.psychosis in a non-English-speaki叩 patient. Correctly differentiating postpartum.psychosis from.other postpartum.psychiatric disorders requires adeptly evaluating for the presence of psychotic sym.tom. with in-depth history taking.

Antim.crobial efficacy of three novel organic sanitizers, CHICO WashTm. C8C10 and CG100, was evaluated for the reduction of Escherichia coli O157:H7 during flum.-washing of organic leafy greens. Organic form.lations at various concentrations: CHICO (C3H8I0C3O7) WashTm.(1:20 ratio) and C8C10 and CG100 (0.2 and 0.4%), along with the controls: hydrogen-peroxide and water, were used for washing organic baby and m.ture spinach and rom.ine and iceberg lettuce. Leafy greens were inoculated with a 2-strain cocktail of E. coli O157:H7 (6 logs CFU/m.) and washed in each treatm.nt for 1 or 2 m.nutes. The treated leafy greens were stored at 4°C and surviving pathogen populations determ.ned on days 0, 1, and 3 of storage. Organic sanitizers, for both treatm.nt tim.s, significantly (P E. coli O157:H7 on all the leafy greens during storage. Highest reduction (3.4 logs CFU/g) was observed after treatm.nt with CG100 (0.4%) in rom.ine lettuce, while CHICO WashTm.showed greater than 2 logs CFU/g reduction on all the leafy greens, by day 3. This study dem.nstrates the potential application of organic sanitizers in flum.-washing of organic leafy greens for the reduction of E. coli O157:H7.

辽河油田Q131区块属于低渗水敏轻质油藏,原始地层压力33.4 m.a,油藏温度98-112℃,地质储量(OOIP)253万m.,地层原油粘度0.5 m.a.s。其特征是油层较厚、地层倾角较大,但地层能量不足,初期压力衰竭开采产量较低。由于渗透率低及水敏严重,后期水驱也未收到成效,目前注水困难,注不进采不出”的矛盾突出。因此,该区块正在考虑实施注气提高采收率技术。注气已经成为一种有效的提高采收率方法,其原理主要在于增加或保持地层压力,提高驱油和波及效率,从而提高原油采收率。根据气源情况,有三种注气技术可以应用于Q131区块:注空气、注CO以及注N。本研究针对Q131工况,考虑了注气高效重力稳定驱替方式在Q131应用的优势,在不同注气技术在目标区块提高采收率机理分析的基础上,对三种技术的技术和经济可行性进行了分析。论文对目标区块的生产历史和及实时数据进行了总结分析,并评估了在本区块进行注气提高采收率的可行性。结合理论分析、注气提高采收率机理、现场经验、室内试验研究、PVT分析和油田生产数据历史拟合,运用Cm.-STARS数值模拟软件,建立三种注气技术应用的油藏数值模拟模型。然后根据注入不同气体对保持地层压力、提高采收率、经济性、安全性等的影响进行筛选。对于注空气工艺,在实验基础上建立低温氧化动力学模型并应用于油藏模拟中。注空气低渗岩心驱替实验表明注空气可以得到比水驱更高的采收率,并且其采收率随着地层倾角的增加而增加。温度在130-170°C的轻质油低温氧化实验表明,油层内的产生的自发低温氧化反应能完全消耗O并且CO转换率高达58%。油藏数值模拟结果表明,受注入井位置和数量限制,气体注入速率及注气量是影响原油产量的重要因素。累积产油量随着气体注入速度和注入量增加而增加,并有注入量的最优值。注空气过程中,在模拟的注入量下生产井未没有出现O突破的现象。以单井30000m./day的速度向地层中注入空气、CO和N(4口注入井)30年,原油采收率分别可达到35%,36.5%,35.5%,其中注入CO的开采效果最好。气体早期突破及油井产出气油比太高是注气工艺的重要问题,关闭的高气油比井是降低气体产出的有效手段。敏感性分析表明,在维持相同注入量下,但采用关闭高气油比油井的方法降低气体产出量,其20年的注入空气、CO和N的原油采收率可分别达到33.5%,36%,and 34%,使得注气项目具有更高的经济性。初期的经济性和安全性分析也证明三种注气技术都具有可行性和经济性。其中,由于操作成本低,注空气成为三种方法中最具前景的方法。此外,详细讨论了不同注气技术安全性和防腐问题,也对低渗油藏更有效开发提出了建议。
