摘要:
A method of making a composite downhole article is disclosed. The method include forming at least one corrodible core member comprising a first material that is corrodible in a wellbore fluid at a first corrosion rate; and disposing at least one outer member on the core member, the outer member comprising a second material that is corrodible in the wellbore fluid at a second corrosion rate, wherein the corrodible core member has a composition gradient or a density gradient, or a combination thereof, and wherein the first corrosion rate is substantially greater than the second corrosion rate. A method of using a composite downhole article is also disclosed. The method includes forming a composite downhole article as described above; using the article to perform a first wellbore operation; exposing the article to the wellbore fluid; and selectively corroding the second corrodible member.

A robot arm assembly a base unit with a shoulder assembly rotatably disposed on the base unit. A lower robot arm is pivotably attached to the shoulder assembly. An upper robot arm is pivotably attached to the lower robot arm. The base unit includes a first motor which rotates a main shaft fixed to the shoulder assembly to rotate the shoulder. A second motor in the base unit rotates a second shaft in the shoulder assembly extending through the main shaft to pivot the lower robot arm with respect to the shoulder.
摘要:
An interconnect structure comprises a solder including nickel (Ni) and tin (Sn), with the nickel in a range of 0.01 to 0.20 percent by weight. The interconnect structure further includes an intermetallic compound (IMC) layer in contact with the solder. The (IMC) layer comprises a compound of copper and nickel.

摘要:
According to one embodiment, an apparatus for opening and closing an overhead door, having a door assembly for mounting to the overhead door, and an operator for securely engaging the door assembly, the operator having a chassis, and a cable reel rotatably mounted to the chassis and coupled to a main cable, wherein, when the main cable is coupled to the door assembly, as the cable reel is rotated in a first direction, the door assembly is drawn towards the operator so as to close the door. The apparatus may further comprise a latch assembly for securing the door assembly to the operator when the door is closed, and a latch release mechanism for selectively disengaging the latch assembly so as to disengage the door assembly from the operator. The overhead door may be biased to the open position so that when the latch assembly is disengaged, the overhead door automatically opens.

Methods for lipomodeling by peripherally administering a modulator of a Y receptor are provided. Methods may comprise reduction of a fat depot by administering a Y receptor antagonist proximally and/or directly to the site of the fat depot. Other methods comprise increasing or stabilizing a fat depot or fat graft by administering a Y receptor agonist proximally and/or directly to the site of the fat depot or fat graft. Also provided are methods for stimulating wound healing by administering a Y receptor agonist proximally to a wound site.

The present disclosure provides systems utilizing fiber optics for monitoring downhole parameters and the operation and conditions of downhole tools and controlling injection operations based on measurements in an injection well and/or a production well.
摘要:
Methods, functional data, and systems are provided for image feature translation. An image is decomposed into sub images, each sub image having its features identified by feature attributes. The feature attributes are used to identify a particular feature within each sub image. The orientation of the particular feature within the sub image is then mapped or calculated to a value. One or more of the mapped or calculated values are translated into a reading associated with an instrument. The reading is then optionally recorded or transmitted.
摘要:
A medical device having a bioactive in a salt and a free-base form contained within the device and/or coated onto a surface of the device. The salt and the free-base form have different solubilities in an aqueous medium. The elution of bioactive from the device in an aqueous medium is tailored by fixing the ratio of forms. Methods of preparing such a device are also provided.
