环己烷是工业上生产环己醇、己二酸和己内酰胺的重要原料,也可用于生产聚酰胺(尼龙-6,6和尼龙6)。在20世纪80年代,首次提出用苯催化加氢的方法制取环己烷,虽然该方法简单且副产物少,但由于环己烷和苯之间沸点差异仅为0.7K,容易形成共沸物,使得原料分离较为困难。因此,通过普通的分离方法很难分离它们。在工业中,通过使用有机溶剂如环丁砜对环己烷和苯进行萃取分离,但有机溶剂选择性较低,并且用量较大,从而增加了工艺成本。离子液体具有强大的萃取和分离能力,并且具有独特的性质,例如宽的液体范围、高的热稳定性、易燃性和可忽略的蒸汽压。本论文旨在解决这些问题,并且评估离子液体作为苯-环己烷分离过程中绿色溶剂的潜力。本论文采用传统溶剂环丁砜和绿色离子液体1-丁基-3-甲基咪唑四氯铝酸盐,对环己烷与苯的分离进行了两次独立的过程模拟研究,两种溶剂均在Aspen Plus(V10)中模拟。通过调节理论塔板数,回流比,馏分率,萃取剂流率,共沸物进料温度和萃取剂进料温度等参数,研究了用这两种溶剂作为萃取剂分离环己烷和苯的可行性,最后在共沸物进料量为450 kg、环己烷质量分数0.8、温度为310 K和压力为515 kPa条件下对传统溶剂和离子液体分离工艺进行了比较,为了获得高达99.50%的环己烷产物的纯度和98.0%的高苯回收率,计算了所需的理论塔板数和溶剂比(S/F)。结果表明:(1)当环丁砜用作萃取剂时,得到的环己烷质量纯度为99.56%,苯回收率为98.13%,总能量消耗为1.36 GJ/t环己烷。在同样的条件下,当n=6时,溶剂比为3;(2)当[BMIM][AlC14]用作萃取剂时,所得环己烷的质量纯度为99.62%,苯回收率为99.32%,总能耗为0.84 GJ/t环己烷。当n=6时,溶剂比为0.4,并且离子液体的损失可忽略不计;(3)通过比较两种分离方法,发现通过两种分离方法得到的环己烷产物的纯度和回收率基本相同,满足分离要求。与环丁砜分离工艺相比,[BMIM][AlC14]分离工艺节省了 38.23%的能源需求和39.33%的成本。本论文的研究成果为离子液体分离环己烷-苯共沸物提供了可行的方向。为了检查两种溶剂的可行性,进行了效率,能量,萃取剂损失和成本分析的比较,并且离子液体在各个方面都表现更优。

寒武系海相碳酸盐岩地层是塔里木盆地深层油气勘探的关键层位,本论文针对塔里木盆地西北部柯坪地区肖尔布拉克剖面的下中寒武统地层,通过微观观测分析了地层的常量元素、微量元素、稀土元素、总有机碳含量(TOC)以及碳氧同位素数据,对目的层碳酸盐岩形成的沉积环境、海平面的高度变化等方面进行了探讨。此外,本论文还分析了全球背景下碳同位素的地层相关性和负漂移,结果显示寒武系玉尔吐斯组、肖尔布拉克组、沙依里克组的碳酸盐岩富含在缺氧环境下沉积的V、Ni、Cu等指示氧化还原环境的元素。但玉尔吐斯组和吾松格尔组的地球化学特征显示,其顶部为亚氧化氧化环境。这可能是因为氧化还原环境受海平面高度的变化控制。中上玉尔吐斯组和沙依里克组揭示古生产力水平的Al/Ti参数高于肖尔布拉克组和吾松格尔组。目的层段稀土元素曲线分布相对平缓,表现为轻稀土元素较少而较重稀土元素富集,指示开阔的海相沉积环境。在玉尔吐斯组和沙依里克组中可以发现?Eu的正异常,指示了热液活动比较活跃。本次研究还观察到两个显著的δC负漂移事件:发育于下-中寒武统边界的“REOCE”事件发育于肖尔布拉克组下部的“CARE”事件。微量元素和碳同位素数据表明,导致δC负漂移的原因可能是由全球海平面上升引起的底部贫C的缺氧水体上涌。研究区内的δC负漂移可以与全球范围内其它区域的“REOCE”事件及“CARE”事件对比,并可以作为地层对比的依据。TOC和微量元素数据表明玉尔吐斯组的泥岩和沙依里克组的碳酸盐岩可能是两套潜在的烃源岩。

In this paper, we propose and analyze a subdivision scheme which unifies 3-point approximating subdivision schemes of any arity in its compact form and has less support, computational cost and error bounds.? The usefulness of the scheme is illustrated by considering different examples along with its comparison with the established subdivision schemes. Moreover, B-splines of degree 4and well known 3-point schemes [1, 2, 3, 4, 6, 11, 12, 14, 15] are special cases of our proposed scheme.

Functional Analysis of MYC2-Like Gene in Cotton Responsive t...

学位级别：硕士

Verticillium wilt of cotton （Gossypium hirsutum） is a widespread and destructive disease that is caused by the soil-borne fungus pathogen Verticillium dahliae. Jasmonic acid （JA） and Salicylic acid （SA） are essential signaling molecules that coordinate the plant response to biotic and abiotic challenges, in addition to several developmental processes. The basic-helix-loop-helix （bHLH） transcription factor （TF） MYC2 has recently emerged as a master regulator of most aspects of the jasmonate （JA） signaling pathway in Arabidopsis. MYC2 coordinates JA-mediated defense responses by antagonistically regulating two different branches of the JA signaling pathway that determine resistance to pests and pathogens, respectively. In present study, a MYC2-like gene, GhMYC2-like, was used and transferred into G. hirsutum cv. YZ-1 （susceptible to V. dahliae）. The transcriptional level of GhMYC2-like was up regulated in transgenic cotton plants as compared to wild types upon JA treatments. It was also observe that GhMYC2-like up regulates the expression of those genes were involved JA-mediated response defense to pathogens. While GhMYC2-like expression was suppressed after SA treatment GhMYC2-like induced transgenic lines were subjected to insect feeding stress. Results revealed that the effects of insect feeding were very less on leaves of transgenic lines that probably due to the GhMYC2-like induced JA defense system against insects. Constitutively overexpressing of GhMYC2-like transgenic plants displayed a noteworthy tolerance against herbivores, which supports our hypothesis. Overall, these results are consistent with the observation that GhMYC2-like is a positive regulator of a subset of JA-responsive genes involved in pathogen and insects stress. Virus induced gene silencing （VIGS） is post-transcriptional gene silence technique, which offers an alternative and complimentary approach for large-scale functional analysis of individual genes by knocking down the expression of endo

Aim: To report a rare case of Spontaneous subcutaneous emphysema and pneumo-mediastinum Introduction: Spontaneous subcutaneous emphysema and pneumo-mediastinum may be defined as the presence of free gas or air in the subcutaneous tissue or mediastinal structures without an apparent precipitating cause. It most commonly occurs in adolescent in good physical health group devoid of severe existing lung pathology. Case Report: In our case, a middle aged married housewife was referred to Department of Medicine, Peoples Medical University Hospital Nawabshah, Sindh, Pakistan, by her local GP for the worsening of her condition due to development of acute neck pain, difficulty in breathing, eating and swallowing (mainly for solid foods) with swelling of neck. She was not complaining of any respiratory symptoms. The chest and neck radiographs showed subcutaneous emphysema and pneumo-mediastinum, there was no any evidence of air leakage from esophagus. She was subsequently put on free fluids, light diet, antibiotics, analgesia and other supportive measures along with close observation. After three days of admission, her clinical symptoms were alleviated to a great extent. She was discharged well from hospital after four days. Conclusion: Spontaneous subcutaneous emphysema with pneumo-mediastinum is medical and surgical emergency. Diagnosis may be made by routine chest X-rays and CT scan of the chest. Prompt diagnosis and immediate management may affect the morbidity and mortality outcomes in this condition.

Purpose： Firearm injuries impose a continuous economic burden on society and hospital resources. The aim of this study was to assess the pattern of bony injuries among victims of gunshots. Methods： A retrospective study was conducted in the Department of Orthopedics, Dow University of Health Sciences and Civil Hospital l〈arachi from January 2011 to December 2012. Patients with isolated bony injuries were included while patients with other systemic injuries were excluded. Results： There were 90 cases and the majority of them were male （84.4%）. Mean age was （32.52 ± 10.27） years. Most of the patients （72.2%） belong to the younger age group. A low velocity weapon was used in 61 （67.8%） cases and a high velocity weapon was used in 29 （32.2%） cases. Armed robbery （64.4%） was the cause of conflict in more than half of the cases. Lower limb was involved in 72.2%. Fifty eight （64.4%） patients remained hospitalized for 15-20 days and others for more than 20 days. Internal fixation with intramedullary nailing was done in 35 patients while K-wire was used in 5 patients. Fifty patients were managed with external fixation, either uniplanar or multiplanar ilizarov. Deep wound infection and nonunion were observed more often in high velocity injuries. Conclusion： Armed robbery was the leading cause of gunshot bony injuries in our hospital. Young males were victimized in a majority of cases. High velocity injuries were associated with more complications.
