摘要： The technology described relates to a process for the safe dissolution of alkali metals, alkaline earth metals, and alloys predominantly comprising at least one thereof. The process comprises contacting the metal with a reaction inhibitor and water. In this process, the reaction inhibitor is selected from a hydrocarbon, a hydroxylated compound, and a mixture thereof. The uses of this process for the quantitative dissolution of metals and their analysis, for the destruction and stabilization of metallic residues, and for the recycling of batteries are also described.

摘要： An improved a method of treating a patient having a disorder responsive to PDE-4 inhibition by administering roflumilast. The improvement involves administering the roflumilast topically in a composition having a roflumilast release profile that produces in the patient a flattened plasma concentration time curve and a reduced Cmax relative to oral administration of a PDE4-inhibiting amount of roflumilast. Such disorders include inflammatory disorders such as inflammatory dermatoses, including psoriasis, atopic dermatitis and seborrheic dermatitis. Such disorders also include inflammatory diseases in a variety of organs, especially the lungs (asthma, COPD). Because of reduced side effects with topical administration due to the improved pharmacokinetics (PK) characteristics, it may be possible to provide higher systemic exposures (AUCs) with topical administration, resulting in greater therapeutic efficacy than with the oral route of administration.

摘要： Methods are provided to inhibit corrosion in low hardness water systems. The corrosion inhibiting treatment comprises: calcium salts of low molecular weight polymer polycarboxylic acids. These calcium salts may be added preformed to the water system in need of treatment or formed in-situ in the system. This method of corrosion inhibition is not a source of addition phosphorous or heavy metal to the treated system.

摘要： Roflumilast crystals have been shown to increase in size during storage. The size of the roflumilast crystals can affect the bioavailability and efficacy of a pharmaceutical composition. The growth of roflumilast crystals can be inhibited during storage by including hexylene glycol in the composition. The resulting composition has improved bioavailability and efficacy and can be used to inhibit phosphodiesterase 4 in a patient in need of such treatment.
