摘要： Gene products of plasmid DNA, such as proteins, are prepared in high yields by cultivating bacteria carrying a plasmid which shows a controlled constant plasmid copy number at one temperature and a much higher or totally uncontrolled copy number at a different temperature. The plasmid may be prepared by recombinant DNA technique using a cloning vector showing the temperature dependent plasmid copy number pattern.
摘要翻译：通过培养携带质粒的细菌，在不同温度下，在一个温度和高得多或完全不受控制的拷贝数下，在一个温度下显示受控的恒定质粒拷贝数，质粒DNA（例如蛋白质）的基因产物以高产率制备。质粒可以通过使用显示温度依赖性质粒拷贝数模式的克隆载体的重组DNA技术来制备。

摘要： The basic fluid is water or an oil-water mixture. The primary weighting materials are dissolved salts, e.g., sodium chloride, calcium chloride or mixed brines, and in these the calcium or sodium ions inhibit hydration and swelling of drilled solids. When non-cationic fluids are used, an inhibitor is added to prevent such hydration and disintegration - an electrolyte or a cationic surfactant. Any viscosifier added is one having neither a structured viscosity nor gel strength, hydroxyethyl cellulose for example. When the drilling fluid is pumped to the surface, most of the drilled solids are in their original condition and size, and are readily removed and discarded by screening and other available physical means. There is none of the build-up of solids associated with older systems, and hence no need for discarding, thinning, and make-up.
摘要翻译：基本的液体是水或油水混合物。主要称重材料是溶解的盐，例如氯化钠，氯化钙或混合盐水，在这些中，钙或钠离子抑制钻井固体的水化和溶胀。当使用非阳离子流体时，加入抑制剂以防止这种水合和崩解 - 电解质或阳离子表面活性剂。任何增粘剂均不具有结构粘度和凝胶强度，例如羟乙基纤维素。当钻井液被泵送到表面时，大多数钻探的固体处于其原始状态和尺寸，并且通过筛选和其他可用的物理手段容易地去除和丢弃。与旧系统相关联的固体没有任何积聚，因此不需要丢弃，变薄和化妆。

摘要： THIS SPECIFICATION DISCLOSES INHIBITION OF FOAMING IN A LIQUID SYSTEM CONTAINING WATER AND A HYDROCARBON. INHIBITION IS EFFECTED BY THE PRESENCE IN THE SYSTEM OF PARTICLES OF A SOLID, INSOLUBLE MATERIAL. THESE PARTICLES HAVE A SURFACE AREA OF LESS THAN 50 SQUARE METERS PER GRAM AND A PORTION OF THEIR SURFACES IS OCCUPIED BY POLAR SITES. REPRESENTATIVE SOLID MATERIALS ARE POLY-2,6-DIMETHYL-1,4-PHENYLENE OXIDE, A COPOLYMER OF 2,6-DIMETHYL PHENOL AND 2METHYL-1,6-TETRADECYL PHENOL WHEREIN THE PROPORTION OF THE LATTER COMPOUND DOES NOT EXCEED ABOUT 20 PERCENT BY WEIGHT OF THE COPOLYMER, A COPOLYMER OF VINYL STEARATE AND MALEIC ANHYDRIDE, SUBLIMED SULFUR, SILICON CARBIDE, AND POLYTETRAFLUOROETHYLENE COMMINUTED UNDER CRYOGENIC CONDITIONS.

摘要： The present invention addresses to a wireline logging method using an aqueous based drilling fluid with xanthan gum and polyols in order to improve the quality of the acquisition of geological data from wireline logging (final logging) in open hole and reducing the risk of the tool getting stuck. It can also be applied in well control situations and used in the integral drilling of the reservoir, but with different application bias of the multifunctional fluid.

摘要： Apparatus and methods for determining the fluid conductivity of a fluid network. The method includes injecting a nanoemulsion into the formation, the nanoemulsion including a carrier liquid and nanodroplets. The nanodroplets are stabilized within the carrier liquid by polymer-coated iron oxide nanoparticles. After extracting fluid from the formation, a parameter of the extracted nanodroplets is determined. Based on the determined parameter, the fluid conductivity of the fluid network is determined.
