Product Information MINIMUM ESSENTIAL MEDIUM EAGLED-VALINE MODIFICATIONProduct Number M7395Storage Temperature 2-8°CProduct DescriptionMinimum Essential Medium (MEM), developed by Harry Eagle, is one of the most widely used of all synthetic cell culture media. Early attempts to cultivate normal mammalian fibroblasts and certain subtypes of HeLa cells revealed that they had specific nutritional requirements that could not be met by Eagle’s Basal Medium (BME). Subsequent studies using these and other cells in culture indicated that additions to BME could be made to aid growth of a wider variety of fastidious cells. MEM, which incorporates these modifications, includes higher concentrations of amino acids. MEM has been used for cultivation of a wide variety of cells grown in monolayers. Optional supplementation of non-essential amino acids to the formulations that incorporate either Hanks’ or Earle’s salts has broadened the usefulness of this medium. The formulation has been further modified by optional elimination of calcium to permit growth of cells in suspension culture.MINIMUM ESSENTIAL MEDIUM EAGLE, Product No. M 7395 is one of the cell culture media available from Sigma. The selection of a nutrient medium is strongly influenced by 1] type of cell, 2] type of culture [monolayer, suspension, clonal] and 3] degree of chemical definition necessary. It is important to review the literature for recommendations concerning medium, supplementation and physiological parameters required for a specific cell line.Components g/L Calcium Chloride•2H2O0.265 Magnesium Sulfate (anhydrous)0.09767 Potassium Chloride0.4 Sodium Chloride 6.8 Sodium Phosphate Monobasic0.122 (anhydrous)L-Arginine•HCl0.126L-Cystine•2HCl0.0313 L-Glutamine0.292L-Histidine•HCl•H2O0.042L-Isoleucine0.052L-Leucine0.052L-Lysine•HCl0.0725 L-Methionine0.015L-Phenylalanine0.032L-Threonine0.048L-Tryptophan0.01L-Tyrosine•2Na•2H2O0.0519D-Valine0.092 Choline Chloride0.001Folic Acid0.001myo-Inositol0.002 Niacinamide0.001D-Pantothenic Acid (hemicalcium)0.001 Pyridoxal•HCl0.001 Riboflavin0.0001 Thiamine•HCl0.001 Glucose 1.0 Phenol Red•Na0.011Precautions and DisclaimerREAGENTFor In Vitro Diagnostic UsePreparation InstructionsPowdered media are extremely hygroscopic and should be protected from atmospheric moisture.

Therefore, users of gasket materials can, by selecting different combinations of statements, specify different combinations of properties desired in various parts. Suppliers, likewise, can report properties available in their respective products.4.Basis of Classification4.1To permit "line call-out" of the descriptions mentioned in 3.2, this classification system establishes letter ornumber symbols or both for various performance levels of each property or characteristic (see Table 1).4.2In specifying or describing gasket materials, each "line call-out" shall include the number of this system (minusdate symbol) followed by the letter "F" and six numerals, for example: SAE J90 (F125400). Since each numeral of the call-out represents a characteristic (as shown in Table 1), six numerals are always required.The numeral "0" is used when the description of any characteristic is not desired. The numeral "9" is used when the description of any characteristic (or test related thereto) is specified by some supplement to this classification system, such as notes on engineering drawings.4.3To further specify or describe gasket materials, each "line call-out" may include one or more suffix letter-numeral symbols, as listed in Table 2, for example: SAE J90 (F125400-B2M4). Various levels of definition may be established by increasing or decreasing the number of letter-numeral symbols used in the "line call-out."TABLE 1—BASIC PHYSICAL AND MECHANICAL CHARACTERISTICS Basic Six-Digit Number Basic CharacteristicFirst Numeral"Type" of material (the principal fibrous or particulate reinforcement material from which the gasketis made) shall conform to the first numeral of the basic six-digit number, as follows:0 = not specified1 = asbestos2 = cork3 = cellulose4 = fluorocarbon polymer5 = flexible graphite7 = nonasbestos, tested as Type 19 = as specified(1)Second Numeral Class of material (method of manufacture or common trade designation) shall conform to thesecond numeral of the basic six-digit number, as follows:When first numeral is "0" or "9," second numeral:0 = not specified9 = as specified(1)When first numeral is "1" or "7," second numeral:0 = not specified1 = compressed sheeter process2 = beater process3 = paper and millboard9 = as specified1When first numeral is "2," second numeral:0 = not specified1 = cork composition (Class 1)2 = cork and elastomeric (Class 2)3 = cork and cellular rubber (Class 3)9 = as specified(1)When first numeral is "3," second numeral:0 = not specified1 = untreated fiber—tag, chipboard, vulcanized fiber, etc. (Class 1)2 = protein treated (Class 2)3 = elastomeric treated (Class 3)4 = thermosetting resin treated (Class 4)9 = as specified(1)When first numeral is "4," second numeral:0 = not specified1 = sheet PTFE2 = PTFE of expanded structure3 = PTFE filaments, braided, or woven4 = PTFE felts5 = filled PTFE9 = as specifiedWhen first numeral is "5," second numeral:0 = not specified1 = homogeneous sheet2 = laminated sheet9 = as specified(1)TABLE 1—BASIC PHYSICAL AND MECHANICAL CHARACTERISTICS Basic Six-Digit Number Basic CharacteristicThird Numeral Compressibility characteristics, determined in accordance with 9.2, shall conform to the percentindicated by the third numeral of the basic six-digit number.

System product performance depends upon a number of factors, including the fastener (material, adhesive and area), application method, surface characteristics (material, texture and cleanliness), environmental conditions (moisture, ultraviolet and temperature exposure) and the time it is expected to support a given load. Because many of these factors are uniquely within the user’s knowledge and control, it is required that the user evaluate 3M products to determine whether they are t for a particular purpose and are suitable for the user’s substrates, method of application and desired end use.Rounding the corners, slightly recessing the product into the substrate, or providing raised edges around the Reclosable fastener can reduce the possibility of edge lifting and improve the overall appearance of the fastener on the nished product. Mechanically securing the corners of the fastener with rivets, staples, screws, etc. may also reduce the possibility of edge lifting, but may reduce the closure performance.The two most common techniques for attaching these 3M hook and loop fasteners to various surfaces are summarized below.Pressure Sensitive Adhesive Attachment: The use of pressure sensitive adhesives eliminates or reduces the need for sewing, solvent activation, dielectric or ultrasonic bonding or bulk adhesive bonding. This can result in simplicity, improved safety and lower installation costs. Pressure sensitive adhesive products can be applied manually or automatically using a variety of equipment choices. Contact your 3M Sales Representative to discuss automated equipment options.Surface Preparation: Highly textured surfaces may reduce the ultimate adhesion levels and care should be given to minimize the surface texture or roughness. Adhesive backed fasteners should be applied to surfaces that are clean, dry and free of oil, grease, dust, mold release agents or surface contaminants that could reduce the adhesion. It is recommended to remove any surface contaminants that may reduce adhesion by using a method suited for the type and quantity of surface contaminants present. Isopropal alcohol is a good general use solvent for cleaning contaminants from surfaces for example.In exceptional cases, especially when removing silicone mold release agents or on rough, porous surfaces, it may be necessary to lightly abrade the surface, use an adhesion promoter, or surface sealer to optimize the adhesive bond to the substrate. The selection of abrasion, priming or sealing methods will depend upon the substrates and the environmental conditions the product will be exposed to during use.Attachment Procedure: To obtain optimum bond to any surface, both the fasteners and the target surfaces should have equilibrated for a minimum of one hour at temperatures between 68°F (20°C) to 100°F (38°C) before application. The liner protecting the adhesive is removed and preferably without touching the adhesive, the fastener is applied to the substrate. Exposure of the adhesive to ambient conditions without the protective liner, before applying to the surface, should be minimized as initial adhesive tack may decrease. Flexible materials should be lying on a hard at surface so as to permit uniform adhesive contact with the surface. Use of a rubber hand roller, press platen or similar device is recommended to ensure full adhesive contact or wet- out with the substrate surface. Approximately 4.5 pounds of force per square inch, (310 grams per square centimeter) is recommended to increase adhesive contact, improving bond strength. For all adhesive applications, it is important to ensure that the edges are rolled down to reduce the chance of edge lifting.Plain backedThe plain backed 3M hook and loop fasteners are most commonly sewn into their applications. Liquid or hot melt adhesives and staples are other forms of attachment that can be utilized.Sewing: Although the selvedge edge was initially developed for stitching on, customers often nd that they get better anchorage when stitching through the 3M hook and loop portions of the fastener – this may be application dependant. The type of thread and stitch type is also best determined based on individual application, however, the fastener should be stitched on all edges for the best seam strength. Typically, special machine adjustmentsare not necessary when using our 3M hook and loop fastenersStorage and Shelf LifeShelf Life when stored in original packaging at 72°F (22°C) and 50% RH is 24 months.Family GroupReferencesISO Statement Technical Information Product Use SJ3401SJ3522SJ3523SJ3526N SJ3527N SJ3402SJ3531SJ3571SJ3572SJ3532N SJ3533N SJ3530Thickness (mm)Test Condition: Unmatedwithout liner2 2.4 3.2 2.4 3.22 3.2 3.2 2.4 2.03 3.05 2.4Thickness (mm)Test Condition: Matedwithout liner3.10.330.330.330.33 3.10.330.330.33 3.3 3.30.33Material Loop-WovenNylon Hook-WovenNylonLoop-WovenNylonHook-WovenNylonLoop-WovenNylonHook-WovenNylonLoop-WovenNylonLoop-WovenNylonHook-WovenNylonHook-WovenNylonLoop-WovenNylonHook-WovenNylonBacking NoAdhesive Sewon Plasticizerresistant acrylicPSAPlasticizerresistant acrylicPSAHighPerformance rubberbased PSAHighPerformance rubberbased PSANoAdhesiveSewonGeneralPurposerubberbasedPSAHighPerformanceAcrylicPSAHighPerformanceAcrylicPSARubberbased PSARubberbased PSAGeneralPurposerubberbasedPSALiner None Nonprintedpolyolen lm Nonprintedpolyolen lmPolyethylene withredprintingPolyethylene withredprintingNone PolypropylenePolyolen withembossed 3MlogoPolyolen withembossed 3MlogoWhitePolypropyleneWhitePolypropylenePolypropylene1.

考试题 “保持持久的学习毅力”是能够在工作中真正学到知识的重要 方法。 “巧妇难为无米之炊”,一般来说,创业者要先有资源,再去 创业。 《中华人民共和国职业分类大典》是我国第一部对职业进行科 学分类的权威性文献。 1959年,美国管理专家德鲁克在他的《明天的地标》 (Landmarks of Tomorrow)”中提出了知识工作者的概念, 其对象类似于现代技术工人。 1959年,美国管理专家德鲁克在他的《明天的地标》(La错误 dmarks of Tomorrow)”中提出了知识工作者的概念,其对象 类似于现代技术工人。 1986年,我国颁布了《注册会计师条例》,提出了第一项职业 资格制度。 E-Lear错误i错误g可以取代面授学习。 不患人不用,患己不用也。 创业的社会性特性是指创业不仅使创业者获得经济利益,实现 自身的社会价值,还为他人提供就业岗位,为社会创造财富。 创业团队首先要了解目标并确定实现目标所必需的活动。对其 生存发展影响重大的关键性活动,应该成为组织设计工作关注 的焦点。 创业中的社会资源也就是在创业过程中需要的技术、市场、管 理、法律等人才,他们是创业者开创事业的辅助力量。 单位人——职业化的单位人——职业人是专业技术人才发展的 一种路径。 当我们的行为背离了自己的价值观的时候我们就会感受到痛苦 。 对于一个组织来说,有想法的专业技术人员是难能可贵的。 对专业技术职业的规范性要求,尤其是职业道德方面的要求自 现代专业技术职业诞生以来就一直伴随着专业技术职业和从业 人员的发展。 法律意义上的“职称”本质上就是专业技术职务。 改善的技能是评价管理者能力的最重要的基准。 根据霍华德理论,企业型人格的代表性职业包括出纳员、统计 员、图书管理员、行政管理助理、邮局职员等。 工作和生活的平衡是不可能实现的理想状态。 工作意味着系统完备的知识体系、意味着一种精神层面的追求 和社会道德体系建设、意味着人生价值观的改变。 管理者要掌握管理方法和技巧,不需要关注新技术和工作的新 知识。 管理知识和技能是专业技术人员应具备的通用知识。 国际劳工组织、美国、英国、澳大利亚、中国等都在根据经济 、社会、科技、文化不断变化的需要修订职业分类目录,明确 每个职业所需要的知识、技能、能力、资格条件、资格管理等 等。 机会是领导给的。 价值观是一个人对各类事物的一般性态度,这种态度表现出比 较明确而单一的趋向和情感,便成为了价值取向。 经营是老板的事,是市场营销人员的事。 经营意味着你要有利害意识、价值意识。狭义地讲经营是要能 够赚钱,广义地讲经营是能够让自己的生命、生活更加符合人 的本性、更加符合生命的意义,使得生活更加有意义,身心都 能够得到愉悦和幸福感。 劳动者不再仅仅将职业作为谋生的手段,而是生活的重要组成 部分,是人生快乐的重要源泉,是体现自我价值的唯一(重要) 途径。

留在大城市发展虽然会辛苦一些,但对于人才成长百利而无一 害。 美国著名学者格林豪斯认为,职业生涯的定义既包含客观部 分,也包含对工作相关事件的主观知觉。 面对严峻的就业形势,更应理性地降低对金钱的期望值,把眼 光放远一些,应尽可能地将自我成长和自我实现作为在自我定 位和求职时的首选价值观。 你可以不做老板,但必须学会经营。 企事业单位的专业技术职务一般实行聘任制。企事业单位的各 级专业技术职务,由行政领导在经过评审委员会评定的符合相 应任职条件的专业技术人员中聘任。行政领导应向被聘任的专 业技术人员颁发聘书,双方签订聘约。 企业的具体培训计划应由人力资源管理部门制定。 气质具有相对的稳定性,但后天也可以锻炼改造。 人不能离开社会而独立存在,个人只有在工作中为社会做贡献 才能实现自己的职业价值。所以在择业中应把尽社会责任摆在 首位,其次考虑个人因素。 人们评价成功的标准是一成不变的。 韧劲几乎是所有取得一定成绩,获得成就的专业技术人员的共 同品质。 上述理论有很多应用测试方法。国外目前最常使用的四种计算 机辅助指导系统为:“发现”、“职业定位系统”、“职业辅 导系统”和“互动式指导系统”。 社会分工越来越细,职业的种类也必将越来越多,且具有多样 性的特点。一些职业的专业性越来越强,需要的知识、技术越 来越深,职业的差别也越来越大,会不断出现(已很难再出 现)精通各个岗位或领域的专家,这也是职业多样化的结果。 双螺旋职业生涯是指外职业生涯和内职业生涯之间的平衡。 随着社会的发展,以服务为主的第三产业类职业将得到全面发 展,在产业结构中的比重将得到很大的提高。 随着社会经济和科学技术的发展,脑力劳动职业发展速度越来 越快,体力劳动职业将越来越少。经济部门和服务性行业的职 业越来越少,行政管理等行业的需求越来越多。 所谓专门人才,是从能力角度对专业技术人员职业特征进行的 界定,即这一职业群体通常必须具备专门的理论知识和专业才 能,需要经过系统的、正规的、全面的教育和培养,拥有较高 的人力资本储备。这是专业技术人员区别于其他职业群体的最 大的特点。 外职业生涯是内职业生涯的主观层面或无形层面,是个人对职 业追求的一种主观愿望,由个人的能力、兴趣、气质、价值观 及对家庭义务、休闲需求等多种因素决定的。 网络究竟能够做到什么程度是个至今仍令人着迷的话题,移动 互联、智能网络、三D打印、大数据时代„„都为今后的职业 发展及活动方式(提供了无限想象的空间)设置了障碍。 未来职业的专业性、技术性、创造性特点越来越强,对劳动者 素质能力的要求越来越高。体力劳动类职业和各种职业中的体 力要求将大大降低,而逐渐被人工智能(脑力劳动和创意性工 作)所代替。 我国专业技术人员继续教育的对象比较广泛,包括大学毕业后 的各类专业技术人员。 无论在什么情况下,创业者都应该设法使用最少的资源去达到 最大的收益。 新创企业在创立之前与成立之初,需要与政府管理部门、金融 部门等进行联系,创业团队良好的人脉关系,有效地处理公共 关系,是创业成功的关键因素之一。 兴趣能够为自己的生活增添乐趣,但对职业选择没有什么影响 。 幸福感取决于实际收入水平。

幸福是比较出来的。 许可类职业资格必须按照行政许可法的要求来进行设置。职业 资格许可制度的核心就是以资格作为判断是否许可执业的手段 。 学习能力一般是指人们在正式学习或非正式学习环境下,自我 求知、做事、发展的能力。 学习型组织强调团队智慧大于个人智慧的平均值。 移动化学习就是把电脑上的学习内容搬到手机里。 影响人才流动的因素,除国家相关法律、政策之外,还有三个 因素:国别工资水平差距、工作生活环境以及互联网(职业资 格的国际互认)。 在进行职业生涯目标确定的时候首先要根据个人的专业、性格 、气质和价值观以及社会的发展趋势确定自己的短期目标。 在准备和撰写专业技术职称申报材料中,专业技术人员可以根 据实际情况对自己任职以来的工作进行美化和拔高。 职称或职业资格代表了一名专业技术人员的职业发展历程,有 高级职称的人或者有职业资格证书的人一定有好的职业发展前 程。 职称与称职、职称与实际能力和贡献之间并非完全等同。 职业的发展性,强调职业对于人自身的发展体现出的价值,人 通过将自己的智慧和精力奉献给所从事的职业,使自己的人生 价值得以体现。可以说,职业是人发展的舞台,任何人的发展 都离不开职业。 职业发展的意识对专业技术人员非常重要。 职业价值是确定一个人职业满意度的关键所在。
