摘要:
Internal combustion engines exhibit improved efficiency of the emissions control system by using a lubricating oil composition of a base oil, an alkali or alkaline earth metal-containing detergent; a metal salt of one or more phosphorus-containing compounds represented by the formula (I), wherein X1 and X2 are independently O or S, and R1 and R2 are independently hydrocarbyl groups, the average total number of carbon atoms in R1 and R2 for the one or more phosphorus-containing compounds being at least 10.4; and an acylated nitrogen-containing compound having at least about 10 alphatic carbon atoms and a TBN of at least about 2; the lubricating oil composition being characterized by a phosphorus concentration of up to about 0.12% by weight and the substantial absence of copper, thereby generating a lean-phosphorus containing exhaust gas.
摘要:
Compositions for improving plant health, the compositions comprising at least one water-soluble pesticide and at least one non-herbicidal water-insoluble agrochemical, are described. Also described are processes for preparing the compositions and methods of improving agronomic crop plant health using the compositions.
摘要:
Hypersulfated disaccharides of formula I and other hypersulfated disaccharides disclosed herein are used to treat diseases or conditions associated with human neutrophil elastase imbalances. The disaccharides and/or intermediates useful to prepare such compounds are prepared from heparin. The diseases and conditions which are treated with a compound of formula I include chronic obstructive pulmonary disorder (COPD) and cystic fibrosis (CF). The formulations are delivered to the lungs in an aerosol formulation or dry powder means or via nebulization. Oral forms are also suitable.
摘要:
Lubricant compositions of (a) an oil of lubricating viscosity; (b) a molybdenum salt; (c) a monoester of (i) a polyol and (ii) an aliphatic carboxylic acid containing about 12 to about 24 carbon atoms; and (d) a borate ester of a vicinal diol containing 12 to 24 carbon atoms provide good fuel economy and power output to internal combustion engines.
摘要:
Disclosed are compounds that are derivatives of brevetoxin, or PbTx, pharmaceutical formulations comprising the compounds, and methods of regulating mucus transport in a cell, treating mucociliary dysfunction and diseases related to decreased mucus transport, wherein the compounds are of the Formula (I), and Formula (III): wherein R, R1, R2, R3, A, n, and Y are as defined herein for each compound.
摘要:
Methods of reducing injury to crop foliage and achieving weed control using encapsulated acetamide herbicides are described. Herbicidal microcapsules comprising herbicide core material and a shell wall encapsulating the core material are also described. The microcapsules provide reduced crop injury through controlled herbicide release.
摘要:
Efficacious herbicidal compositions comprising a derivatized saccharide surfactant and an amine oxide surfactant are described. The compositions are characterized as having low toxicity and are readily biodegradable.
摘要:
Solid and liquid pesticidal concentrate and spray compositions are described which exhibit enhanced efficacy due to the addition thereto of a compound which increases EPSPS enzyme inhibition by the pesticide, cell membrane permeability, or expression of hydroxyproline-rich glycoproteins.
摘要:
In a network of computer nodes, a directory service provides both the physical location of directory information around the network and the directory information itself in a single data structure. This single data structure is distributed throughout the network, and continuously redistributed, so as to create a directory service that is both more flexible, and more robust, than prior art directory services.
摘要:
A low-sulfur, low-phosphorus composition comprising an oil of lubricating viscosity; a substantially nitrogen-free sufurized olefin antiwear agent; a nitrogen-containing dispersant; and an overbased detergent selected from the group consisting of salixarates, saligenins, salicylates, and glyoxylates; containing less than about 0.1 percent by weight phosphorus, less than about 0.5 percent by weight sulfur, and having less than about 1.2% sulfated ash, is useful for lubricating a diesel engine, exhibiting good antiwear performance.
