    • Wellhead assembly and method for providing a power connection to a downhole electrical device, such as a heater. Pressure-containing wellhead body members enclose a vertical wellbore and support therein an isolated tubing hanger and a grounding tubing hanger. The isolated tubing hanger suspends a conducting tubing string, while the grounding tubing hanger suspends a grounding tubing string concentrically spaced from the conducting tubing string. The isolated tubing hanger has an outer housing, an inner electrically conducting portion supported by the outer housing operative to provide electrical connection with, and suspend, the conducting tubing string, and insulation between the housing and conducting portion to electrically isolate the housing portion. Hot electrical connection is made for electrical connection to the conducting portion of the isolated tubing hanger or the conducting tubing string. Electrical isolation seals and electrically isolates the hot electrical connection from the wellhead body members. Grounding connection is provided to a wellhead body member. A source of current provides a first connection to the hot electrical connection and a second connection to the grounding connection.

    • Plant tissue specific gene expression by way of repressor-operator complexes, has enabled outcomes including, without limitation, male sterility and engineered plants having root-specific gene expression of relevant proteins to clean environmental pollutants from soil and water. A mercury hyperaccumulation strategy requires that mercuric ion reductase coding sequence is strongly expressed. The actin promoter vector, A2pot, engineered to contain bacterial lac operator sequences, directed strong expression in all plant vegetative organs and tissues. In contrast, the expression from the A2pot construct was restricted primarily to root tissues when a modified bacterial repressor (LacIn) was coexpressed from the light-regulated rubisco small subunit promoter in above-ground tissues. Also provided are analogous repressor operator complexes for selective expression in other plant tissues, for example, to produce male sterile plants.
    • 通过阻遏物 - 操作复合物的植物组织特异性基因表达,已经实现了包括但不限于雄性不育和具有相关蛋白质的根特异性基因表达的工程植物从而清除土壤和水中的环境污染物的结果。 水银超累积策略要求汞强反应酶编码序列强烈表达。 肌动蛋白启动子载体,A2pot,被设计成含有细菌lac操纵子序列,在所有植物营养器官和组织中指示强表达。 相比之下,当修饰的细菌阻遏物(LacIn)从地上组织中的光调节的rubisco小亚基启动子共表达时,来自A2pot构建体的表达主要限于根组织。 还提供了用于在其他植物组织中选择性表达的类似的阻遏物操纵子复合物,例如产生雄性不育植物。

    • The invention relates to redox-switchable material comprising a redox-active moiety adsorbed, bonded or both, to a semiconductor material. Among the preferred redox-active moieties disclosed herein are ferrocenes, acridines, and quinones though any such moiety may be employed. The redox-switchable material of this invention may be used to selectively remove one or more selected solutes from an aqueous solution wherein adsorption/complexation of the solute is influenced by the oxidation state of the redox-active moiety. In an alternative embodiment, inclusion moieties that are covalently bound to the redox-active moiety are employed to achieve selective complexation of the desired solute. Other possible applications of the disclosed materials are photoerasable writing media, electrochromic or photochromic materials, catalysis, and solar energy storage.
