Disclosed is an animal litter that includes a palm oil residue, possibly in combination with another absorbent material such as whole ground grain, virgin germ, seed meal, spent germ or clay. The palm oil residue may be palm kernel cake, palm oil sludge, or palm pressed fiber. Also disclosed are a method for removing animal waste and a process for preparing an animal litter. The method for removal of animal waste includes allowing an animal to excrete waste into a container that includes a litter, the litter comprising a palm oil residue. The process for preparing an animal litter comprises combining the materials that make up the litter to form the litter.
摘要:
The present invention pertains to the use of the protein phenylalanine ammonia-lyase, as well as the biologically-active derivatives of the said protein for preventing or treating diseases associated with a phenylalanine imbalance in a human or animal body. More particularly, the present invention relates to the therapeutic use of the above-cited molecules for preventing or treating a phenylalanine imbalance in vivo. This invention also deals with therapeutic compositions comprising a pharmaceutically active amount of the above-described therapeutic molecules as well as with therapeutic methods using the said therapeutic compositions. Finally, the present invention relates to processes for selecting more therapeutically-effective variants of said protein as well as to the selected variants themselves.
摘要:
A dark-field imaging method for detecting defects in reflective lithography masks (e.g., extreme ultraviolet (EUV) masks) used, e.g., in processes for the fabrication of microelectronic devices. A mask blank is coated with a photoresist layer having a fluorescent dye incorporated therein. The photoresist layer is exposed to a source of radiation (e.g., EUV radiation or glancing soft X-rays). In areas of the mask blank having defects the combined direct and reflected radiation will be insufficient fully to expose the photoresist layer. After development, photoresist will remain on the mask blank surface in areas corresponding to defects. Illumination with the excitation wavelength of the fluorescent dye reveals the location of any remaining photoresist, which can be detected using an optical microscope, thereby to detect defects in the mask blank.

Disclosed is an automatically-activated wireless code symbol reading system comprising a bar code symbol reading mechanism contained within a hand-supportable housing having a manually-activatable data transmission switch. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e.g. product, bar code menu, etc.) so that the bar code symbol is scanned, detected and decoded in a cyclical manner. Each time the scanned bar code symbol is successfully read during a bar code symbol reading cycle, a new bar code symbol character string is produced, while an indicator light on the hand-supportable housing is actively driven. During the bar code symbol reading cycle, the user actuates the data transmission switch producing a data transmission control activation signal and enabling a currently or subsequently produced symbol character data string to be automatically selected and transmitted to the host system. By virtue of the present invention, automatically-activated hand-supportable bar code symbol readers are now able to accurately read, in an unprecedented manner, bar code symbols on bar code menus, consumer products positioned in crowded point-of-sale environments, and other objects requiring automatic identification and/or information access.
摘要:
Olefins are polymerized by novel transition metal complexes of selected iminocarboxylate and iminoamido ligands, sometimes in the presence of cocatalysts such as alkylaluminum compounds or neutral Lewis acids. Olefins which may be (co)polymerized include ethylene, α-olefins, and olefins containing polar groups such as olefinic esters for example acrylate esters. Also described are certain “Zwitterionic” transition metal complexes as polymerization catalysts for making polar copolymers. The resulting polymers are useful as thermoplastics and elastomers.
摘要:
This invention concerns olefins having a terminally disposed fluorocyclobutyl ring bearing an ionic functionality or a precursor thereto, a process for the production thereof, and polymers formed therefrom.
摘要:
Transition metal complexes of selected monoanionic phosphine ligands, which also contain a selected Group 15 or 16 (IUPAC) element and which are coordinated to a Group 3 to 11 (IUPAC) transition metal or a lanthanide metal, are polymerization catalysts for the (co)polymerization of olefins such as ethylene and α-olefins, and the copolymerization of such olefins with polar group-containing olefins. These and other nickel complexes of neutral and monoanionic bidentate ligands copolymerize ethylene and polar comonomers, especially acrylates, at relatively high ethylene pressures and surprisingly high temperatures, and give good incorporation of the polar comonomers and good polymer productivity. These copolymers are often unique structures, which are described.

摘要:
Certain complexes containing ligands having a phosphino group, amino group or an imino group, and a second functional group such as amide, ester or ketone, when complexed to transition metals, catalyze the (co)polymerization of olefinic compounds such as ethylene, &agr;-olefins and/or acrylates. A newly recognized class of ligands for making copolymer containing polar monomers using late transition metal complexes is described.

This invention pertains to olefins having a terminally disposed fluorocyclobutyl ring bearing a sulfonyl, sulfonic acid or sulfonate salt, a process for the production thereof, and polymers, especially ionomers, formed therefrom. The invention further pertains to ionically conductive compositions formed by the combination of a liquid and the ionomer of the invention, and electrochemical devices such as electrodes, sensors, and solid polymer electrolytes comprising those conductive compositions. The polymers of the invention arc useful in the formation of films and coatings with high chemical resistance and good physical properties. The ionomers of the invention are useful in electrochemical applications, particularly in lithium batteries. The polymeric compositions of the invention are useful for strong acid catalysis, such as Friedel-Crafts alkylation.
