Methods of assuring that a representative formation and/or fluid sample of a subterranean reservoir is obtained are provided. One method of validating a reservoir fluid sample obtained from a wellbore includes the steps of acquiring a reservoir fluid sample in the wellbore; measuring a property of the fluid sample downhole with a technique to obtain a measured downhole fluid property; replicating ...

An information management system is described comprising one or more workstations running applications to allow a user of the workstation to connect to a network, such as the Internet. Each application has an analyser, which monitors transmission data that the application is about to transmit to the network or about to receive from the network and which determines an appropriate action to take reg...

A fiber comprising an isotactic propylene homopolymer characterized as having 13 CNMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity.

The present application describes a specific tracer delivery system that has been tested. The claimed system is composed of melamine formaldehyde resin (MFR) doped with various tracer materials. The MFR is used to slowly release tracer compounds into a liquid system. The MFR/tracer mixture is applied as part of a monitoring system where tracer is delivered from the MFR/tracer mixture at a specific...

Fischer-Tropsch synthesis is performed on a CO/H*2 feed gas using a plurality of compact catalytic reactor modules ( 12 ) each defining catalytic reaction channels and coolant channels, in two successive stages, with the same number of reactor modules for each stage. The gas flow velocity in the first stage is sufficiently high that no more than 75% of the CO undergoes conversion. The gases are co...

The invention provides gypsum wallboard, made from gypsum-containing slurries having outstanding hydration rate characteristics comprising alpha-hemihydrate ground to a particular particle size distribution range and having a Blaine surface area in the range from about 3100 cm2/g to about 9000 cm2/g, alone or in combination with beta-hemihydrate.

Set retarders of copolymers of at least one polymerizable ethylenically unsaturated monomer and at least one alkoxylated sulfate, phosphate or ketonic salt are capable of delaying the hardening of a cementitious slurry when introduced into a subterranean formation until a downhole temperature greater than or equal to 500° F. is obtained, even in the absence of an intensifier. The ethylenically uns...

A coated substrate is configured with one or more cross-linked interfacial zones provided to improve the adhesion between the coating and substrate of the article or between adjacent coating layers. The coating composition contains molecules having at least two reactive functional groups capable of reacting with cross-linking molecules in the substrate and/or molecules in adjacent coating layers. ...

The invention relates to an apharesis device for use in the treatment of Alzheimer patients. Said device comprises a solid support with which a flow of blood or plasma can be contacted.

Drum type washing machine including a tub of plastic having a wall for holding washing water therein and mounting a driving part thereon, a drum rotatably arranged inside of the tub, a shaft passed through the tub and connected to the drum for transmission of a driving power from a motor to the drum, at least one bearing for supporting the shaft, a bearing housing having a bearing supporting part ...

An audience measurement system (10) collects data representative of tuned programs rather than of tuned channels, and includes (i) a household metering apparatus (14) which records ancillary codes or extracts program signatures from the programs if no ancillary codes are found therein, (ii) a reference apparatus (32) which monitors broadcast programs to be monitored, which extracts reference signa...

The invention relates to a composite artificial grass fibre for use in an artificial lawn, in particular an artificial grass sports field, which artificial grass fibre is made up at least of several monofilament fibres. The invention further relates to an artificial lawn, in particular an artificial grass sports field built up of a substrate to which composite artificial grass fibres according to ...

A filled composite material, preferably having fire retardant or non-combustible properties, comprising a preformed syntactic composite material (1) of particulate structure defining interstitial spaces between the particles thereof, and a filler material (2) which may be aqueous or resin based, drawn into the interstitial spaces by applying to the composite material a partial vacuum.

Consiste en una guillotina para el corte del banano de forma segura, rapida y estetica, que elimina ademas el dano en el gajo de banano, dado el corte fino y parejo que hace de este. Consta de un eje horizontal que sirve de soporte a la estructura, una barra transversal movil, un pedal, barras guias, una viela de movimiento, barras de transmision, un pivote de pedal, una mandibula inferior y una m...

Mejora al bloque de concreto convencional utilizado en la mamposteria reforzada fabricado por el sistema de vibrocompactacion

A dispensing device (1) is proposed for dispensing a liquid (2), in particular containing or consisting of a drug, as a fine spray (3). A high fraction of small particles can be achieved by using a duct (5) or slit (22) having a flat cross section.

The device has a carrier rotating system (2) with a number of grip arm elements (1), a grip arm promoter (4) behind the other grip arms that can be promoted. The grip arm promoter is maintained such that each grip arm across the direction aligned edge (11) can be promoted. During this promotion, pile edge is aligned on the carrier edge which can be seized. Carriers are equipped for receiving and c...

A system for attaching a shade material to a roller having recesses in its surface includes inserting portions of the shade material into an associated elongated recess and retaining the material in the recess with an attachment member having peaks and valleys along its length for intermittent engagement with the material within the recess.
