A method for reducing longitudinal flow of fluids through an annular space surrounding a permeable well tubular, such as a slotted liner or a sandscreen, in an inflow region of an oil and / or gas production well having: arranging a series of collapsed resilient sealing rings at regular longitudinal intervals around the permeable tubular before lowering the tubular into the well by means of tape and / or a binder which dissolves downhole; placing the tubular in the inflow region of the well; and allowing the tape and / or binder to dissolve, thereby allowing the resilient sealing rings to expand radially in the annular space surrounding the permeable tubular.

A microfluidic chip formed with multiple fluid channels terminating at a tapered electrospray ionization tip for mass spectrometric analysis. The fluid channels may be formed onto a channel plate that are in fluid communication with corresponding reservoirs. The electrospray tip can be formed along a defined distal portion of the channel plate that can include a single or multiple tapered surfaces. The fluid channels may terminate at an open-tip region of the electrospray tip. A covering plate may substantially enclose most portions of the fluid channels formed on the channel plate except for the open-tip region. Another aspect of the invention provides methods for conducting mass spectrometric analysis of multiple samples flowing through individual fluid channels in a single microfluidic chip that is formed with a tapered electrospray tip having an open-tip region.

A fluid end for a reciprocating pump including a body having a base, a side and a longitudinal opposing side, a cylinder bore formed horizontally through the body and a vertical bore intersecting the cylinder bore defining a high stress region proximate the intersection, and a tension member extending through the body substantially parallel to the longitudinal axis of the body, wherein the tension member provides a compressive load on the body reducing the stresses encountered in the region during operation of the fluid end.

The present invention discloses a method, includes: receiving uplink control plane signaling or uplink control plane signaling and uplink user plane media data sent by a UE; performing, encapsulation and conversion on the uplink control plane signaling or the uplink control plane signaling and the uplink user plane media data, and sending the uplink control plane signaling or the uplink control plane signaling and the uplink user plane media data after the encapsulation and conversion to a TCF; receiving downlink control plane signaling or downlink control plane signaling and downlink user plane media data sent by the TCF; and performing encapsulation and conversion on the downlink control plane signaling or the downlink control plane signaling and the downlink user plane media data, and sending the downlink control plane signaling or the downlink control plane signaling and the downlink user plane media data after the encapsulation and conversion to the UE.

The present invention discloses a computer system and program product. A computer system including an algorithm for computing a characteristic value of a matrix comprising steps of; providing a first matrix comprising M rows and N columns (M-by-N matrix); providing second matrixes by randomly selecting rows from the first matrix, each of the second matrixes including predetermined numbers of rows smaller than the numbers of rows of the first matrix; computing the characteristic values for the second matrixes; plotting each of the characteristic values with respect to the predetermined numbers of rows; and extrapolating the plots to said number of rows of the first matrix so as to obtain a characteristic value of the first matrix.

An electronic device. The electronic device comprising a host, and a module structure is disposed in the host for calculating data. The module structure has a first substrate, a process unit, a heat-dissipating device and a second substrate. The first substrate is a motherboard of the electronic device, and the process unit is disposed on the first substrate, and the heat-dissipating device is attached to the process unit and disposed on the first substrate. The first substrate and the second substrate have the same structure and texture. The first substrate and the second substrate are blanketed from a multi-layer structure or sheet used for the motherboard.

An automated pharmaceutical or biotech compound testing system uses a very small molded plastic shelf keeping unit or test tube known as a “minitube”. The minitubes are stored in trays in a standing refrigeration unit and are retrieved by a machine or robot having a die cutting tubular end effector adapted to selectively cut away and remove a minitube from an integrally molded matrix containing hundreds of minitubes (e.g., 384); the matrix is called a minitube well plate. Upon cutting a selected minitube away from the matrix, the end effector is pushed down over the selected minitube, thus forcing the minitube into the cylindrical interior lumen of the end effector, where it is retained by friction fit until such time as the minitube is to be releaseably locked into a plastic receiving tray. Minitubes are stored in the plastic tray which is adapted to receive and releaseably hold or lock the tubes in place. The minitubes themselves are molded plastic tubes having distally projecting spaced apart “rabbit ear” detent lock members which are biased outwardly. The plastic receiving tray has apertures sized to receive the minitubes and each aperture of the tray is terminated at bottom in a hole defined within chamfered shoulders adapted to slidably engage and exert transverse force against the minitube rabbit ears. The two rabbit ears and the hole together comprise a detent lock system, the minitube rabbit ears releaseably engage the shoulder surfaces on the bottom of the hole in each aperture of the tray. The robot end effector can withdraw and replace the tubes as needed to perform automated testing.

Disclosed is a hybrid broadband optical source comprising an amplified spontaneous emission (ASE) light source module to generate ASE, a gain medium to amplify the ASE, a pump light source to generate pump light, and a wavelength selective coupler to supply the pump light to the gain medium.

A method of making phenol and alkylphenol ethoxylates non-estrogenic by inserting 1 mole of propylene oxide onto the phenolic group before proceeding with the addition of ethylene oxide or mixtures of ethylene and propylene oxide. The final phenolic products can be further reacted to form sulfates, sulfonates, phosphate esters, condensed alkylphenol alkoxylates and other derivatives of alkylphenol or phenol. Non-estrogenic phenol and alkylphenol alkoxylates and their derivatives have been found to be excellent salt tolerant, high temperature stable surfactants for oil recovery from subterranean reservoirs. These products are also useful in forming emulsions of heavy crude for transportation through pipelines.

The present invention relates to sealed containers or pouches. More specifically, the present invention relates to containers, such as flexible packages or bags wherein the containers or pouch can be compressed or evacuated to remove excess air, fluid or other gaseous content and then sealed in such compressed or evacuated arrangement.
