Robustα-Fe_(2)O_(3)/Epoxy Resin Superhydrophobic Coatings for Anti-icing Property

α-Fe_(2)O_(3)/epoxy resin composite superhydrophobic coating was prepared withα-Fe_(2)O_(3) nanoparticles and epoxy resin by spin coating method.The coating without epoxy resin has higher contact angle(CA)and lower ice adhesion strength(IAS),but the mechanical properties are poor.Theα-Fe_(2)O_(3)/epoxy resin composite superhydrophobic coating exhibits good mechanical durability.In addition,compared with the bare aluminum substrate,the Ecorr of the composite coating is positive and the Jcorr is lower.The inhibition efficiency of the composite coating is as high as 99.98%in 3.5 wt%NaCl solution.The difference in the microstructure caused by the two preparation methods leads to the changes in mechanical properties and corrosion resistance of composite superhydrophobic coating.

Study of Flow and Heat Transfer in an Ejector-Driven Swirl Anti-Icing Chamber

The formation of ice on the leading edge of aircraft engines is a serious issue,as it can have catastrophic consequences.The Swirl Anti-Icing(SAI)system,driven by ejection,circulates hot fluid within a 360°annular chamber to heat the engine inlet lip surface and prevent icing.This study employs a validated Computational Fluid Dynamics(CFD)approach to study the impact of key geometric parameters of this system on flow and heat transfer characteristics within the anti-icing chamber.Additionally,the entropy generation rate and exergy efficiency are analyzed to assess the energy utilization in the system.The research findings indicate that,within the considered flow range,reducing the nozzle specific areaφfrom 0.03061 to 0.01083 can enhance the ejection coefficient by over 60.7%.This enhancement increases the air circulating rate,thereby intensifying convective heat transfer within the SAI chamber.However,the reduction inφalso leads to a significant increase in the required bleed air pressure and a higher entropy generation rate,indicating lower exergy efficiency.The nozzle angleθnotably affects the distribution of hot and cold spots on the lip surface of the SAI chamber.Increasingθfrom 0°to 20°reduces the maximum temperature difference on the anti-icing chamber surface by 60 K.

Neurosyphilis complicated by anti-γ-aminobutyric acid-B receptor encephalitis: A case report

BACKGROUND Syphilis is an infectious disease caused by Treponema pallidum that can invade the central nervous system,causing encephalitis.Few cases of anti-N-methyl-Daspartate receptor autoimmune encephalitis(AE)secondary to neurosyphilis have been reported.We report a neurosyphilis patient with anti-γ-aminobutyric acid-B receptor(GABABR)AE.CASE SUMMARY A young man in his 30s who presented with acute epileptic status was admitted to a local hospital.He was diagnosed with neurosyphilis,according to serum and cerebrospinal fluid(CSF)tests for syphilis.After 14 d of antiepileptic treatment and anti-Treponema pallidum therapy with penicillin,epilepsy was controlled but serious cognitive impairment,behavioral,and serious psychiatric symptoms were observed.He was then transferred to our hospital.The Mini-Mental State Examination(MMSE)crude test results showed only 2 points.Cranial magnetic resonance imaging revealed significant cerebral atrophy and multiple fluidattenuated inversion recovery high signals in the white matter surrounding both lateral ventricles,left amygdala and bilateral thalami.Anti-GABABR antibodies were discovered in CSF(1:3.2)and serum(1:100).The patient was diagnosed with neurosyphilis complicated by anti-GABABR AE,and received methylprednisolone and penicillin.Following treatment,his mental symptoms were alleviated.Cognitive impairment was significantly improved,with a MMSE of 8 points.Serum anti-GABABR antibody titer decreased to 1:32.The patient received methylprednisolone and penicillin after discharge.Three months later,the patient’s condition was stable,but the serum anti-GABABR antibody titer was 1:100.CONCLUSION This patient with neurosyphilis combined with anti-GABABR encephalitis benefited from immunotherapy.

Imperialism in Current Film Industry——Take Hollywood as the Example

In current patterns of media, old media and new media both prevail in modern society. Since media is a too broad term, this article will focus on the film industry. It will state whether the imperialism of Hollywood, a typical media giant, exists in the film industry and its influence on cultural globalization.

Mindset Shaping by Media: An Overview of Media Technologies Leading towards Media Imperialism in Media Mix

When medium itself has become message and gets disproportionate importance, the substance of the message gets pushed back. Influence of visual media on culture and people has been increasing day by day. Though it influences people both positively and negatively, it affects more adversely than otherwise as the media has begun affecting the very identity of the masses and reduced them to passive subjects. The plurality of culture and identity of people in the third world countries are at stake. Strong resistance of the masses supported by a new order of international information is the need of the hour. Keeping this in mind, a revisit to the influence of visual media is deliberated here.

Literary Art as a Vehicle for the Diffusion of Cultural Imperialism in the Nigerian Society： The Example of Chimamanda Adichie＇s Purple Hibiscus

This paper takes a cursory look at the conceptual framework of what cultural imperialism entails with particular study of its socio-political consequences in contemporary Nigerian society, and a closer look at the transportation and importation of western cultural values and the implantation of same in Nigeria thereby almost completely eclipsing the hitherto African cultural conservatism of the Nigerian state. Clear examples of this cultural transplant are given in this work, including but not limited to the use of English language in place of the indigenous languages for communication even when there are no foreigners, smoking of cigarettes, ladies putting on trousers, abortions as a means of birth control, free premarital and extramarital sexual relationships, and homosexuality and gay practices. These which were viewed as an anathema to Nigeria＇s cultural values have supplanted the traditional conservatism of the Nigerian people. This work particularly looks at Chimamanda Adichie＇s Purple Hibiscus and distills classical cases of cultural imperialism. Adichie through the character Eugene, captures cultural imperialism as seen in the life of this vastly brainwashed ＂been-to＂ who is clearly portrayed as an imperial lackey, capitalist, and apologist. Also, the character of Rev. Father Benedict, a Briton, who often found any indigenous songs in St. Agnes Parish was quite offensive. The work also captures cultural imperialism in the ironical contempt with which the catholic devotee, Eugene, treats his own father, Papa Nnukwu, steeped in the traditional African cultural values, and Eugene viewes him as Godlessness. The essay concludes by identifying the cultural crises that cultural imperialism creates in the Nigerian state, and recommends ways of diluting and diffusing the present cultural imperialism as a solution to the myriad of socio-political crises currently experienced by the Nigerian society.

The Impact and the Solutions of English Linguistic Imperialism

English linguistic imperialism is that the dominance of English as a world language and sets out to analysis how the language became so dominant. It looks at the spread of English, in order to ascertain whether the language has actively promoted as aninstrument of the foreign policy of the major English-speaking states, and if so, in what ways.Last, it will provide a description of language pedagogy, the scientific study of language learning and language teaching, has beenisolated from the social sciences and political disconnection.

Linguistic Imperialism: An Inevitable Trend

English,as a global language,has expanded on many countries and fields.With the spread of English,scholars started to look at the influence it has brought to culture,economy,and politics.Even though English is accepted by different countries,the debate on its spread and influence is always in a hot spot.As linguistic imperialism being used to describe the position of English,it is also contentious.

The Spread of “Cultural Imperialism” and The Rebounds of China's Movie & TV

With the marked globalization of cultural transmission and wide opening of the Chinese market, Chinese movie & TV industry faces unprecedented opportunities and challenges as well. What we face is not only the enormous impact of the economic form of film industry; what is more, in the field of culture, we will also face the enormous impact of"cultural imperialism". This paper focuses on the"cultural imperialism"existed in global especially American films. To counter the cultural empirical globalization of American films growing in great intensity, this paper discusses the theory of"culture rebounds"presented earliest in France. Moreover, under the influence of the theory especially in Chinese film circles, it makes research and analysis to deal with the present situation.

Global English Usage and Linguistic Imperialism

English spreading from a tiny scale to a global dimension, allowing countries and citizens to participate fully in global prosperity. English gradually becomes dominant in educational, political, economic and cultural aspects. Regarding the dominance of English as a neutral international language, rather than the evidence of linguistic imperialism can be controversial.

“体用排偶”与明清制义的文体特征

“制义”是明清科举考试中经义文体的正式名称,“八股文”则是对经义文体的俗称。明代官方正式文件从不称其科举文体为“八股文”,明代的经义文集一般不以“八股文”为书名,“八股文”一词不能准确、全面揭示明清经义文的文体性质和特点。《明史·选举志》指出“体用排偶”是明代制义主体部分的文体形态特点。“排偶”包括排比和骈偶,骈偶类包括两扇、四段、六股、八股、十股、十二股、十六股等。在排比类中存在着一种股数为奇数的排比形态,如三股文、五股文、七股文、九股文,可统称为“奇股文”。奇股文的存在应引起我们重视,明清制义文体的本质与特点需要重新认识。决定明、清制义“排偶”部分文体形态的,是题目的句型结构特点和语义结构特点。当然,作者的修辞理念和兴趣也对其“排偶”设置产生影响。明代成化之后,八股形态在“排偶”诸形态中占据主流地位,这既与它契合传统文章学理念有关,也与科举考试的标准化进程是相呼应的。

清代书院课艺:联结书院学与科举学的历史文献

在上千年的中国书院史上,多数书院都重视以考促学。从流传形态来看,清代书院课艺主要分为课艺原件、编入别集中的课艺和以书院名义选编的课艺总集三大类别;就主课艺内容而言,清代书院课艺大体包括制艺试帖、经史词章、时务西学等门类。书院课艺数量与书院数量、考课次数、书院额数和刊刻频率直接相关。尽管历史上汗牛充栋的书院课艺多已散佚,但其现存数量依旧十分巨大,无法准确估算。清代书院课艺具有一定的经学、文学、史学、书院学和科举学价值,深入挖掘其中的有用元素,可以从书院考课内容与科举考试内容、考课衡文标准与科举衡文标准、书院育人目标与科举取士目标、科举人物的思想观念与关系网络、书院生徒平时成绩与科考录取率等方面,考察书院学与科举学的共生和互动关系。

宋代科举试论程式化之演进与成因——兼谈科举文体的程式迁移与定型

宋代科举试论程式化进程始于北宋熙丰年间,而非传统看法中的南宋初年。这一转变与王安石科举改革引经义入科场密切相关。试论程式中的官题与论腰两部分直接源于经义程式,试论的程式化实乃经义程式迁移的结果。而这种迁移最早发生于北宋后期的太学,之后随时文刊本的传播而普及。试论程式虽始终未被官方制度化,但因便于考生仿效且为考官阅卷提供了便利,故在应举人数增加、试论篇幅渐长的南宋同时受到考生和考官的青睐,最终成为双方心照不宣的试论写作与评判标准。

论苏轼与元祐秘书省职官的诗歌唱和

诗歌唱和成为元祐间苏轼与秘书省文人交游的重要手段,成为引人注目的诗歌现象。苏轼在元祐间与秘书省职官唱和之作数量较多,他们的唱和之作多出于交游、宴饮、雅集过程之中,基本不涉及时政国事,在新旧法之争、洛蜀党争激烈之元祐间,体现出苏轼与这些秘书省职官们的情感选择。苏轼与这些秘书省职官皆博学高才之士,他们的唱和之作是文人逞才斗艺的一种创作形式,力求诗意深邃、用字精巧、事典广博、用韵严谨、句式规范,体现出“以才学为诗”的特征,使宋诗的题材、笔法、结构、语言等方面的特点愈加鲜明,为推动整个元祐诗坛的繁荣起到了积极的作用。

宋代的科举考试立法——敕、令、格、式

宋代科举取士重立法。《贡举条制》是科举考试法的总称,其下又有敕、令、格、式等细化管理。科举条制从宋初沿唐制,至真宗朝始制订本朝《科举条制》,由疏而密。科举条制历经仁宗《庆历贡举条制》,神宗《熙宁科举条制》,哲宗朝元祐、元符条制修订的反复,徽宗朝《政和新修贡士敕令格式》,南宋《绍兴重修贡士敕令格式》的五次改革。宋代仅存的丁度《贡举条式》反映了科举条制在实践中的不断变化。两宋科举敕、令、格、式的延续修订,反映出宋代朝廷重视建立科举考试法,目的在于公正、公平科举考试取士。这种追求与努力也是宋代科举制能延续至元、明、清的一个重要原因。

丧钟敲响:皇族内阁的社会反响与抗议风潮

1911年皇族内阁成立后,遭到各方反对。有的官员公开表达不满,本为阁员的官员的表态则暴露出清廷最高层的矛盾;各报刊给予持续的批评和讥讽;以各省咨议局联合会为中心的立宪派人士多次上书抗议,又联络各团体抗争,成为反对皇族内阁的核心,并引发持续的抗议风潮。立宪派人士反对皇族内阁的根本原因,在于他们完全不信任清廷权贵,不相信他们能领导国家走出危机。在国会请愿后出台的皇族内阁,使本已十分尖锐的清政府与立宪派及社会各方的矛盾更为激化,等于敲响了清王朝的丧钟。

北齐后期发敕、发诏授官及其影响——以《文馆词林·敕上·除授》为中心

《文馆词林》保存的北齐后期皇帝除授官员职务的“敕”分为两类:一为“件授如右”敕,是北齐皇帝对吏部上奏官职拟选名单的批复,它是吏部铨选运作的一个重要环节;二为以皇帝名义发布的除授官员职务敕,它与发诏授官同属官职除授的重要形式,但各有对应的官职除授范围。北齐后期皇帝发诏、发敕授官和“件授如右”敕,不仅与唐代“册授”“制授”“敕授”和“旨授”存在渊源关系,是唐代选授之法的重要来源,而且对唐代制敕授官文书产生了重要影响。

汉唐西北地区基层行政的帝制化

秦汉时期,中国完全进入帝制社会。帝制社会体现在很多方面,基层行政组织也不例外。近代以来,甘肃、新疆、青海、内蒙古西部等西北地区发现了大量秦汉至唐宋时期的文献资料。这些出土文书内容丰富,资料原始性强,其中大量有关县以下基层行政组织的记载,是研究秦汉以来乡、里、村、坊等基层行政制度实施与推行的珍贵史料,是西北地区逐步进入帝制社会曲折历程的历史见证。西汉武帝时期,在推行郡县制的同时,内地实施的乡里制也推行于河西走廊地区。十六国北朝时期,汉以来的以西乡、东乡、北乡、都乡等为代表的方位名乡制及里的建制在河西走廊地区以及吐鲁番地区得以沿袭和实施,地方行政体系排列顺序基本上是郡—县—乡—里。唐朝时期,内地基层行政制度推行于更向西的以羁縻州制为主的西域地区。与县以上体制多变比较,西域地区的基层行政体系更具有稳定性。总体而言,随着唐的基层行政制度在西域地区的全方位推行,西北地区最终完成了帝制社会化历程。

“仙都玉京”与“幻灭之城”:龚自珍的京师梦寻

龚自珍6岁之时随母进京,出仕之后又一直担任京官,北京是其想象中的“仙都玉京”,亦是历经坎坷之后的“幻灭之城”,这座城市的文化精神深深融入了龚自珍的人格建构与文学书写中。从进京寻梦之初“东华飞辩少年时,伐鼓撞钟海内知”的意气风发,到中途“东华环顾愧群贤,悔著新书近十年”的失意、失语,再到挥别京师之时“布衣三十上书回,挥手东华事可哀”的幻灭感,正是龚自珍京师梦寻的复杂心路。
