Enzyme Activity DeterminationAssay the activity of alanine aminotransferase (ALT) in serum(Mohun’s Method)* Enzyme activity is the ability of an enzyme to catalyze a specific reaction and a measure of quantity of enzyme present .* Reaction rate can be measured as disappearance of reactant or accumulation of product per unit time under some condition such as identified reactant and product,reaction time and temperature.A unit of enzyme activity is the amount of enzyme activity which will catalyze thetransformation of 1 micromole of the substrate per minute under standard conditions. The unit has the symbol “U”.The plasma concentration of most enzymes remains fairly constant in the case of a normal individual. It will be altered if there is:a) Change of synthesis of enzymes within the cell;b) Cellular damage;c) Change in the size of enzymes forming tissue ;d) An alteration in the rate of inactivation and disposal of enzymes;e) An obstruction to a normal pathway of enzyme excretion.The serum nonfunctional enzyme determinations are particularly helpful in clinical medicine, it may be useful to:a) Assess the severity of the organ damage;b) Differentiate a particular type of disease;c) Follow the trend of the disease;d) Determine post-operative risk.Normally the serum transaminase levels are low but after extensive tissue destruction these enzymes are liberated into the serum.Liver tissue is rich in Aspartate Transferase (AST) and alanine aminotransferase (ALT), but contains more of ALT than of AST. Therefore measurement of the serum levels (activity) of ALT is to ascertain the potential for liver cell damage.Principle:The quantitative of serum ALT reflect the damage of liver cell. Activities of serum ALT were determined colorimetrically according to Mohun (1957).ALT can catalyze the transamination: ALTL-Alanine+α-ketoglutarate↔Pyruvate+ Glutamic acidThen, 2,4-dinitro-phenylhydrazine is added for stopping the reaction and marron compounds are formed which response to a-ketoacid. The absorbance at 520nm of the product formed from pyruvate is bigger than that from a-ketoglutarate. So we can detect the activity of ALT by spectrophotometry.In this experiment, one Unit of ALT activity in serum is defined as the amount of enzyme needed to produce 2.5μg of pyruvate per ml serum after it is incubated with the substrate at 37o C, pH 7.4 for 30 min.Procedure:Accurately pipette into 4 tubes respectivelyTest (1) Test Blank (2) Standard (3) Standard Blank (4)Substrate buffer 0.5 0 0.5 0.5Put the tubes into water bath at 37oC for 1 minSerum 0.1 0.1 0 0Pyruvate (200μg/ml)0 0 0.1 0Phosphate buffer 0 0 0 0.1Mix the tubes sufficiently, and put into water bath at 37oC for 30 min.2,4-dinitro-phenylhydrazine 0.5 0.5 0.5 0.5Substrate buffer 0 0.5 0 0Mix the tubes, and put into water bath at 37oC for 20 min0.4 mol/L NaOH 5.0 5.0 5.0 5.0Mix the tubes, after 20 min at room temperature, read A 520 within 30 min using distilled water adjusting A to zero.Calculation: ALT enzyme activity= (A1-A2)/(A3-A4)x 20/2.5x 1/0.1 ( Mohun’s Uni酶活性测定测定丙氨酸转氨酶的活性(ALT)血清(莫哈巴的方法)酶活性是一种去催化一个特定反应的能力和一种衡量酶存在量的方法。

"Dancing at the Edge of the World: Thoughts on Words, Women, Places".《世界边缘的舞蹈:关于语言、女性和地方的思考》Introduction:In "Dancing at the Edge of the World," Ursula K. LeGuin explores the intersection of language, women, and places. She writes about the power of words, the role of women in society, and the importance of our connection to the places we inhabit. Through a series of essays, LeGuin invites readers to think critically about these topics and consider how they shape our understanding of the world.Chapter 1: LanguageConclusion:第二篇示例:IntroductionEnglish literature translation is an important field in the study of language and culture. The translation of English literature involves not only the linguistic translation of words or sentences but also the transfer of cultural meaning and emotional resonance. This article will discuss the challenges and techniques of translating English literature, as well as the importance of preserving the original author's voice and style in the translated text.Challenges in translating English literature第三篇示例:Title: The Importance of Translation of Full English TextsTranslation plays a crucial role in bringing different languages and cultures together. More specifically, translating full English texts into different languages allows for access to valuable information and insights that may otherwise be inaccessible to those who do not speak English. In this article, we will explore the importance of translating full English texts and the benefits it brings.第四篇示例:Abstract: This article discusses the importance of translating English literature and the challenges translators face when putting together a full-text translation. It highlights the skills and knowledge needed to accurately convey the meaning and tone of the original text while preserving its cultural and literary nuances. Through a detailed analysis of the translation process, this article emphasizes the crucial role translators play in bridging the gap between languages and making English literature accessible to a global audience.IntroductionEnglish literature is a rich and diverse field encompassing a wide range of genres, styles, and themes. From classic works by Shakespeare and Dickens to contemporary novels by authors like J.K. Rowling and Philip Pullman, English literature offers something for everyone. However, for non-English speakers, accessing and understanding these works can be a challenge. This is where translation comes in.Translation is the process of rendering a text from one language into another, while striving to preserve the original meaning, tone, and style of the original work. Translating afull-length English text requires a deep understanding of both languages, as well as a keen awareness of the cultural andhistorical context in which the work was written. Additionally, translators must possess strong writing skills in order to convey the beauty and complexity of the original text in a new language.Challenges of Full-text TranslationTranslating a full-length English text poses several challenges for translators. One of the most significant challenges is capturing the nuances and subtleties of the original work. English literature is known for its rich and layered language, with intricate wordplay, metaphors, and symbolism that can be difficult to convey in another language. Translators must carefully consider each word and phrase in order to accurately convey the author's intended meaning.Another challenge of full-text translation is maintaining the author's unique voice and style. Each writer has a distinct way of expressing themselves, and a good translator must be able to replicate this voice in the translated text. This requires a deep understanding of the author's writing style, as well as the ability to adapt it to the conventions of the target language.Additionally, translators must be mindful of the cultural and historical context of the original work. English literature is deeply rooted in the history and traditions of the English-speaking world, and translators must be aware of these influences in orderto accurately convey the author's intended message. This requires thorough research and a nuanced understanding of the social, political, and economic factors that shaped the work.Skills and Knowledge RequiredTo successfully translate a full-length English text, translators must possess a wide range of skills and knowledge. First and foremost, translators must be fluent in both the source language (English) and the target language. This includes a strong grasp of grammar, syntax, and vocabulary in both languages, as well as an understanding of the cultural and historical context of the works being translated.Translators must also have a keen eye for detail and a meticulous approach to their work. Every word, sentence, and paragraph must be carefully considered and translated with precision in order to accurately convey the meaning of the original text. This requires strong analytical skills and a deep understanding of the nuances and complexities of language.Furthermore, translators must possess strong writing skills in order to craft a compelling and engaging translation. Translating a full-length English text is not simply a matter of substituting one word for another; it requires creativity, imagination, and a deep appreciation for the beauty of language. Translators mustbe able to capture the rhythm, cadence, and tone of the original work in their translation, while also adapting it to the conventions of the target language.ConclusionIn conclusion, translating a full-length English text is a complex and challenging task that requires a high level of skill, knowledge, and creativity. Translators must possess a deep understanding of both the source and target languages, as well as the cultural and historical context of the work being translated. Through their careful and meticulous work, translators play a crucial role in making English literature accessible to a global audience, bridging the gap between languages and cultures. By preserving the beauty and complexity of the original text in their translations, translators enrich our understanding of literature and bring the works of English authors to readers around the world.。

01 The Language of MusicA painter hangs his or her finished pictures on a wall, and everyone can see it. A composer writes a work, but no one can hear it until it is performed. Professional singers and players have great responsibilities, for the composer is utterly dependent on them. A student of music needs as long and as arduous a training to become a performer as a medical student needs to become a doctor. Most training is concerned with technique, for musicians have to have the muscular proficiency of an athlete or a ballet dancer. Singers practice breathing every day, as their vocal chords would be inadequate without controlled muscular support. String players practice moving the fingers of the left hand up and down, while drawing the bow to and fro with the right arm—two entirely different movements.Singers and instruments have to be able to get every note perfectly in tune. Pianists are spared this particular anxiety, for the notes are already there, waiting for them, and it is the piano tune r’s responsibility to tune the instrument for them. But they have their own difficulties; the hammers that hit the string have to be coaxed not to sound like percussion, and each overlapping tone has to sound clear.This problem of getting clear texture is one that confronts student conductors: they have to learn to know every note of the music and how it should sound, and they have to aim at controlling these sound with fanatical but selfless authority.Technique is of no use unless it is combined with musical knowledge and understanding. Great artists are those who are so thoroughly at home in the language of music that they can enjoy performing works written in any century.01音乐的语言画家将已完成的作品挂在墙上,每个人都可以观赏到。

[2] 迅速增多的大量研究工作——迄今已有104 个研究项目,涉及大约15 000人——证明乐观的态度可以使你更快乐、更健康、更成功。
与此相反,悲观则导致无望、疾病以及失败,它与沮丧、孤独、令人苦恼的腼腆密切相关。
休斯敦莱斯大学的心理学家克雷格•A•安德森说:“如果我们能够教会人们更积极地思考,那就如同为他们注射了预防这些心理疾病的疫苗。
”[3] “你的能力固然重要,”匹兹堡卡内基–梅隆大学的心理学家迈克尔•F•沙伊尔说,“但你成功的信念影响到你是否真能成功。
”在某种程度上,这是由于乐观者和悲观者以截然不同的方式对待同样的挑战和失望。
[4] 以你的工作为例。
宾夕法尼亚大学的心理学家马丁•E•P•塞利格曼与同事彼得•舒尔曼在一项重要研究中对大都会人寿保险公司的推销员进行了调查。
他们发现,在工龄较长的推销员中,积极思考者比消极思考者要多推销37% 的保险额。
在新雇用的推销员中,乐观主义者则多销了20%。
[5] 公司受到了触动,便雇用了100 名虽未通过标准化行业测试但在态度乐观一项得分很高的人。
这些本来可能根本不会被雇用的人售出的保险额高出一般的推销员10%。
[6] 他们是如何做到的呢?据塞利格曼说,乐观主义者成功的秘诀就在于他的“解释方式”。
出了问题之后,悲观主义者倾向于自责。
他说:“我不善于做这种事,我总是失败。
”乐观主义者则寻找漏洞,他责怪天气,抱怨电话线路,甚至怪罪别人。
他认为,是那个客户当时情绪不好。
当一切顺利时,乐观主义者居功自傲而悲观主义者只把成功视为侥幸。

Discussion about the application of the anchor bar on theslope constructionFu Ming Fu , Zhang TianAbstract:There are some advantages in strengthening slope with the anchor bar, such as low project cost, convenient for construction and so on. It not only meets the requirement of the reliability of the construction, but also is economic and reasonable for the construction.Key words: anchor bar; slope; strengthening1.IntroductionAnchor technique uses strata geotechnical’s shear strength around bolt to deliver structures pulling force or keep strata of the excavation own stability. Due to the use of the anchor rod, Anchor strata produce compressive zone and have reinforcement effect to strata, can enhance the strength of strata, improve mechanical properties of strata, make structure and stratum together formed a kind of work together complex. Anchor system can effectively sustain tension and shear, improve shear strength of the potential sliding surface, so it can effectively prevent slope to produce sliding damage.Fig 1 after excavation of the slope2.Project profileThe length of a slope is about 60m, the most slope height is about 23m,the angle up to 50°~ 75°, a five-layer frame structure buildings is far from about 1.5 to 4m at its base edge, its foundation is artificial bored pile and its bearing stratum is in weathered phyllite. Due to the strong weathering of rocks, it was chunky, loosely structured, multi-muddy filling. It has residual slope deposits of silty clay overlying and local folder with a pulpy, low strength. Slope hadcollapsed at various locations, it is vary dangerous to the building, so we need to reinforce the slope, and we use stone concrete retaining wall and bolt to support it.3.Bolt retaining and protecting design3.1Bolt design(1)all formation of anchor use whole length bond-type, the binder materials are ordinary cement mortar, the mortar strength grade is M30, the anchor length L is 10 meters, the slope height h is 9 meters. Anchoring section length is 5m.(2)According to the construction condition and the needs of the process, the layout form of anchor use quincunx, and in order to make the anchoring force in the role of surface rock surface with uniform, the two adjacent line bolts should be staggered arrangement.(3)The anchor’s number according to /3.24 per meter to calculation, the anchor length is L, a tolal of 252. The diameter of drilling holes is φ90,the number of drill according to (L-0.1)m per hole to calculation, M30 grout number according to average 0.052m3per hole to calculation.(4)The two adjacent rows vertical spacing of anchor take 2.55m, horizontal spacing take 2.55m. The dip angle of anchor: with the angle of horizontal line is 20°, and drilling down with this Angle.(5)Anchor use the steel bar, which is HRB400 level, 28mm diameter.3.2Anchor calculation(1)The calculation of lateral geotechnical pressure[1][2]When the supporting structure to leave in rock and earth mass direction migration until to the limit equilibrium state, the geotechnical pressure which is role in supporting structure called active geotechnical pressure. Its calculation method is as follows:For the slope which has no flare structure surface, generally speaking, failure is controled by rock mass strength, the calculation formula is same to the active soil pressure, but cohesive force C take zero, internal friction angle ϕuse eϕ(rock mass equivalent internal friction angle) instead of, according to the standard to selection; rupture angle is 45°+ϕ/2(ϕis rock mass internal friction angle, is estimationed by haircut at the standard of rock mass internal friction angle, reduction factor according to the standard to selection).According to the engineering survey, active rock pressure can calculation as follows:(2)the calculation of anchor tension design value a Q ak N N γ= (1)(2) In the formula: a N is anchor tension design value; ak N is anchor tension standard value; Q γis partial load factor, take 1.3; tk H is the horizontal tension standard value of anchor; αis the dip angle of anchor.Through the calculation, ak N =112.3kN a N =145.99kN(3)the calculation of anchor steel section area(3) In the formula: S A is the steel section area of anchor; ογ is slope engineering importance coefficient(the slope engineering importance coefficient of this project is level 1, take 1.1); 2ξis the tensile working conditions coefficient of anchor bar ( permanent anchor take 0.69, temporary anchor take 0.92); y f is the tensile strength design value of anchor bar(standard value k y f =400a MP , design value y f =360a MP ).According to the calculation, S A ≥0.5883210m -⨯,choose level 3 steel of 1φ28mm,S A =0.6153210m -⨯.(4)The calculation of anchorage body and rock mass anchoring lengthanchoring length should not only meet the requirements which the bond force of formation on mortar and the bond stress of mortar on steel, but also meet the requirements that the Structure design codes the Minimum anchoring length.(4) In the formula: a l is the anchoring length; D is the diameter of anchorage body; rb f is the bond strength eigenvalue of layer and anchorage body, through the experiment or local experience sure, or according to the standard to selection ( this engineering ’s rock mass uniaxial compressive 2222111209tan (45)2090.217175.77/2222e a aE H K kN m ϕγ︒==⨯⨯⨯-=⨯⨯⨯=cos tkak H N α=2a S yNA f ογξ≥1ak a rbN l Df ξπ≥strength is 7.46a MP , belong to soft rock, rock mass structural plane development, rb f take 300a KP );1ξis the bond working conditions coefficient of anchorage body and layer (permanent anchor take 1.00).According to the calculation, a l ≥4.3m, take a l =5.0m.(5)The anchoring length between anchor steel and anchor mortara l ≥ (5) In the formula: a l is the anchoring length between steel and mortar; d is the diameter of anchor bar; n is the number of steel;b f is the bond strength design value between steel and anchor mortar, through the experiment sure, or according to the standard take 2.40; 3ξ is the working conditions coefficient of steel and mortar bond strength(permanent anchor take 0.60). According to the calculation, a l ≥2.1m ,take a l =5.0m.3.3 The construction technology and key points of anchorThe anchor ’s construction technology is as follows: build-up scaffold ——excavate and clear up the slope surface ——measures to fix position ——drill hole ——washing hole ——bolt put in a certain place ——grout ——colligation the end of the anchor ——flushing the slope surface ——pouring frame space ——Spray seed(1)This slope belong to rocky slope, after excavate the slope 10 cm to the underside of the frame space, set bolt and pouring frame space, then spray grass or seeds after borrowed soil 20 cm in the frame space.(2)the slope should be payed attention to clean up, when construction. The anchor should be placed after wash hole, then put pressure (0.4MPa) and grout. After the mortar fully solidification, colligation steel, cast-in-place reinforced concrete frame space, bend the end of the anchor and bind point by point with the skeleton steel.(3)Before drilling, the hole should be measured to fix position and then do mark. Pitch deviation is less than 150mm, hole depth error is less than 50mm. Try not remold the surrounding rock, when drill. Before Put the anchor, it should be attentioned that blow wash clean the water of the hole and rock powder and so on, and rust removal the body of rod.

As Phillipson sees it, leading institutions and individuals within the predominantly "white" English-speaking world, have (by design or default) encouraged or at least tolerated—and certainly have not opposed—the hegemonic spread of English, a spread which began some three centuries ago as economic and colonial expansion.同时,他认为这些政策和他称之为语言歧视(和种族歧视、性别歧视的情况类似)的偏见密切相关。

Its calculation method is as follows:For the slope which has no flare structure surface, generally speaking, failure is controled by rock mass strength, the calculation formula is same to the active soil pressure, but cohesive force C take zero, internal friction angle ϕuse eϕ(rock mass equivalent internal friction angle) instead of, according to the standard to selection; rupture angle is 45°+ϕ/2(ϕis rock mass internal friction angle, is estimationed by haircut at the standard of rock mass internal friction angle, reduction factor according to the standard to selection).According to the engineering survey, active rock pressure can calculation as follows:(2)the calculation of anchor tension design value a Q ak N N γ= (1)(2) In the formula: a N is anchor tension design value; ak N is anchor tension standard value; Q γis partial load factor, take 1.3; tk H is the horizontal tension standard value of anchor; αis the dip angle of anchor.Through the calculation, ak N =112.3kN a N =145.99kN(3)the calculation of anchor steel section area(3) In the formula: S A is the steel section area of anchor; ογ is slope engineering importance coefficient(the slope engineering importance coefficient of this project is level 1, take 1.1); 2ξis the tensile working conditions coefficient of anchor bar ( permanent anchor take 0.69, temporary anchor take 0.92); y f is the tensile strength design value of anchor bar(standard value k y f =400a MP , design value y f =360a MP ).According to the calculation, S A ≥0.5883210m -⨯,choose level 3 steel of 1φ28mm,S A =0.6153210m -⨯.(4)The calculation of anchorage body and rock mass anchoring lengthanchoring length should not only meet the requirements which the bond force of formation on mortar and the bond stress of mortar on steel, but also meet the requirements that the Structure design codes the Minimum anchoring length.(4) In the formula: a l is the anchoring length; D is the diameter of anchorage body; rb f is the bond strength eigenvalue of layer and anchorage body, through the experiment or local experience sure, or according to the standard to selection ( this engineering ’s rock mass uniaxial compressive 2222111209tan (45)2090.217175.77/2222e a aE H K kN m ϕγ︒==⨯⨯⨯-=⨯⨯⨯=cos tkak H N α=2a S yNA f ογξ≥1ak a rbN l Df ξπ≥strength is 7.46a MP , belong to soft rock, rock mass structural plane development, rb f take 300a KP );1ξis the bond working conditions coefficient of anchorage body and layer (permanent anchor take 1.00).According to the calculation, a l ≥4.3m, take a l =5.0m.(5)The anchoring length between anchor steel and anchor mortara l ≥ (5) In the formula: a l is the anchoring length between steel and mortar; d is the diameter of anchor bar; n is the number of steel;b f is the bond strength design value between steel and anchor mortar, through the experiment sure, or according to the standard take 2.40; 3ξ is the working conditions coefficient of steel and mortar bond strength(permanent anchor take 0.60). According to the calculation, a l ≥2.1m ,take a l =5.0m.3.3 The construction technology and key points of anchorThe anchor ’s construction technology is as follows: build-up scaffold ——excavate and clear up the slope surface ——measures to fix position ——drill hole ——washing hole ——bolt put in a certain place ——grout ——colligation the end of the anchor ——flushing the slope surface ——pouring frame space ——Spray seed(1)This slope belong to rocky slope, after excavate the slope 10 cm to the underside of the frame space, set bolt and pouring frame space, then spray grass or seeds after borrowed soil 20 cm in the frame space.(2)the slope should be payed attention to clean up, when construction. The anchor should be placed after wash hole, then put pressure (0.4MPa) and grout. After the mortar fully solidification, colligation steel, cast-in-place reinforced concrete frame space, bend the end of the anchor and bind point by point with the skeleton steel.(3)Before drilling, the hole should be measured to fix position and then do mark. Pitch deviation is less than 150mm, hole depth error is less than 50mm. Try not remold the surrounding rock, when drill. Before Put the anchor, it should be attentioned that blow wash clean the water of the hole and rock powder and so on, and rust removal the body of rod. When grouting, builders 3a bN n df ογξπshould attention the grouting pressure and mortar ratio.Fig 2 anchor field construction drawing4.ConclusionIt is economical to reinforcement slope with bolt, and use the normal equipment, It is not only achieve safe and also economy and rational.(1) Today bolt technology is widely used in the project. It is an effective reinforcement measures to constraints sliding soil with the combining of bolt and concrete slope protection.(2) We must be sure to do geological exploration work of the slope to find out the nature of the rock and hydrogeological situation before reinforcing slope by grouting bolt.(3) Due to the factors of engineering geological conditions, grouting pressure and construction technology, we should be given adequate attention to the quality of construction.Reference[1]Technical code for building slope engineering (JGJ 120-99).
