    • The present invention relates to methods for isolating and storing, nucleic acid from a sample containing nucleic acid, such as a cell sample or cell lysate. The nucleic acid is isolated on a solid phase medium, which is then dried, and which can be stored efficiently, such as at room temperature, in columns, tubes, and microwell plates having a wide variety of filters and other solid phase media, for extended periods of time, including days, weeks, and months. The invention provides methods for isolating and storing nucleic acid from a sample by applying the sample to a solid phase medium, retaining the cells, lysing the cellular retentate, drying the medium and retaining the nucleic acid, storing the nucleic acid for extended periods of time at room temperature and humidity, and optionally eluting the nucleic acid. The invention provides methods for storing nucleic acid-containing samples on a wide range of solid phase media in many types of tubes, columns, or multiwell plates, many of which are commercial available.

    • Previous MIMO systems have used spatially diverse antenna elements in order not to reduce the number of orthogonal channels that can be realized. The present invention recognizes that this leads to large antenna sizes, as compared to multiple beam antenna systems which use closely spaced antenna elements. In order to provide a compact antenna unit, while still allowing a MIMO system to be exploited, the present invention recognizes that polarization diversity only can be used in a MIMO system without the need for spatially diverse antenna elements. Closely spaced antenna elements are used and this enables a compact MIMO antenna unit to be provided. In addition, such MIMO systems with polarization diversity but no spatial diversity can advantageously be used in line of sight situations and also combined with multi-beam antenna systems to further increase capacity.
    • 先前的MIMO系统已经使用空间多样的天线元件,以便不减少可以实现的正交信道的数量。 与使用紧密间隔的天线元件的多个波束天线系统相比,本发明认识到这导致大的天线尺寸。 为了提供紧凑的天线单元,在仍然允许利用MIMO系统的情况下,本发明认识到仅在MIMO系统中可以使用极化分集,而不需要空间多样的天线元件。 使用紧密间隔的天线元件,这使得能够提供紧凑的MIMO天线单元。 此外,具有极化分集但没有空间分集的这种MIMO系统可以有利地用于视线情况,并且还可与多波束天线系统组合以进一步增加容量。

    • A method of managing lost returns in a wellbore is disclosed. The method includes contacting a filter cake with a treating fluid to remove metallic weighting agents from the filter cake, wherein the filter cake is disposed on a face of a formation fracture in the wellbore. The method also includes contacting the filter cake with a proppant slurry, wherein the proppant slurry contacts the filter cake concurrently with the treating fluid or after the treating fluid contacts the filter cake. This method may include increasing the filter cake permeability and may utilize a barite removal agent, such as a chelation agent. At least one related wellbore management method is disclosed, which provides for creating a fracture in the wellbore and propping open the fracture to increase wellbore integrity to utilize higher weight drilling fluids and prevent fractures from forming further down the wellbore.
    • 公开了一种在井眼中管理丢失回报的方法。 该方法包括使滤饼与处理流体接触以从滤饼中除去金属加重剂,其中滤饼设置在井眼中的地层断裂面上。 该方法还包括使滤饼与支撑剂浆料接触,其中支撑剂浆料与处理流体同时接触滤饼,或处理流体接触滤饼之后。 该方法可以包括增加滤饼渗透性,并且可以使用重晶石去除剂,例如螯合剂。 公开了至少一个相关的井筒管理方法,其提供在井眼中产生断裂并支撑打开裂缝以增加井筒完整性以利用更高重量的钻井液并防止裂缝进一步向下形成井筒。
