The present invention is directed to methods and media for the isolation and presumptive identification of various bacteria. In particular, the organisms commonly associated with urinary tract infections are distinguished based on their colonial morphology and color.

This invention relates to growth media for capturing and sustaining the growth of conifer embryogenic tissue and conifer embryos. Using media of the invention allows good growth of embryogenic tissue and conifer embryos which can subsequently be germinated to obtain plants. With these media there is no need to use plant regulator/hormones such as auxins and/or cytokinins for embryogenic tissue cature and maintenance.

Thermally shock stable bonded solid materials are formed by mixing a solid mineral or inorganic material in an aqueous medium with a lignosulfonate, treating the aqueous medium with a metal ion- based complexing agent (such as lime), with application of heat sufficient to maintain the lignosulfonate in fluid form, so as to produce an intimate mix of saturated slaked lime with lignosulfonate and the mineral or inorganic material, and thoroughly mixing the resulting substantially dry material with...

A recording medium comprises an ink-receiving layer comprising a pigment and an alkali-process gelatin, wherein the alkali-process gelatin has no sol-gel reversibility in an environment of room temperature and has a weight average molecular weight within the range of from 50,000 to 150,000. A coating aqueous dispersion comprises water and has dispersed therein a pigment and the alkali-process gelatin. A process for producing a recording medium comprises the steps of coating on a support at room ...

A recording element which comprises a recording layer containing, a first charge-generating material adapted to generate a first electric charge by a supply of external energy, a first charge-transporting material for transporting the first electric charge, a charge-capturing material for capturing the first electric charge, and a material having an electro-optical effect, wherein a change in optical properties of the recording layer is caused only through an inner electric field to be generated...

The present invention provides a filtration medium comprising an ultrafiltration membrane and a monomer surface coating thereon of an acrylic or methacrylic acid monomer having alcohol functional groups, wherein the filtration medium after having been fully dried is characterized by having a titer reduction of at least about 10.sup.3 with respect to PP7 bacteriophage and a critical wetting surface tension of at least about 70 mN/m. The filtration medium preferably further comprises a fibrous non...

Microscopy specimens are infused with and embedded in a low viscosity medium whose composition comprises: a low viscosity epoxy resin, a moderately low viscosity epoxy flexibilizer, an anhydride hardener, and an accelerator. The composition's viscosity is low enough to permit thorough infusion into a wide range of specimens, including endosperms with a high lipid content, tissues with hard, lignified cell walls, and highly vacuolated parenchymatous tissues of ripe fruits.

A magnetic recording medium for high density recording comprising a support having thereon a magnetic recording layer comprising a ferromagnetic metal powder of the Fe-Co-Cr-B system and having a coercive force of about 700 to 500 oersteds in the oriented direction of the magnetic substance and a residual magnetic flux density of about 1500 gausses or more, the residual magnetic flux density of which after storage for 160 hours under the conditions of a temperature of 60.degree.C and 90%RH is 85...

A thermistor material of between 99% and 50% by weight of praseodymium oxide and 1 to 50% by weight of zirconium oxide provides a stable thermistor with desired resistance value changes over a temperature range of 100.degree.C to 600.degree.C. Other selected oxides may be used in place of zirconium. Small amounts of indium or gallium oxides can also be added to the mixture to lower the resistivity and temperature coefficient of resistance.

A standard breath alcohol test medium comprises a canister containing a charge of nitrogen and vaporized alcohol having a predetermined amount of alcohol per unit of volume therein, and means on the canister accommodating discharge of the nitrogen and alcohol mixture therefrom, preferably by pressure discharge or hypodermic extraction through a self-sealing septum in the wall of the canister. A method for filling the containers with a predetermined amount of alcohol vapor is also disclosed.
