摘要:
A lead frame has a flag, a peripheral frame, and main tie bars coupling the flag to the peripheral frame. At least one cross tie bar extends between two of the main tie bars and an inner row of external connector pads extending from an inner side of the cross tie bar and an outer row of external connector pads extending from an outer side of the cross tie bar. Both an inner non-electrically conductive support bar and an outer non-electrically conductive support bar are attached across the two of the main tie bars. The inner non-electrically conductive support bar is attached to upper surfaces of the two of the main tie bars and to upper surfaces of the inner row of the external connector pads.

摘要:
The present invention relates to a method for producing ultra-clean gasoline. The invention provides a method of hydro-upgrading inferior gasoline through deep desulfurization and octane number recovery, which comprises the following steps: cutting inferior full-range gasoline into the light and heavy fraction gasolines; contacting the light fraction gasoline successively with a catalyst for selective diene removal and a catalyst for desulfurization and hydrocarbon aromatization/single-branched-chain hydroisomerization; contacting the heavy fraction gasoline with a catalyst for selective hydrodesulfurization, and contacting the reaction effluent with a catalyst for supplemental desulfurization and hydrocarbon multi-branched-chain hydroisomerization; and blending the treated light and heavy fraction gasolines to obtain the ultra-clean gasoline product. The method of the invention is suitable for hydro-upgrading inferior gasoline, especially for hydro-upgrading inferior FCC gasoline with ultra-high sulfur content and high olefin content to obtain excellent hydro-upgrading effects.

The present technology relates to compounds of Formulas (V) and (VI) and methods of making and using such compounds. Methods of use include prevention and treatment of hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, hepatic steatosis, and metabolic syndrome. Compounds disclosed herein also lower total cholesterol, LDL-cholesterol, and triglycerides and increase hepatic LDL receptor expression, inhibit PCSK9 expression, and activate AMP-activated protein kinase.
摘要:
The present invention describes a novel process for the conformal coating of polymer fibers on nonwoven substrates. This process is based on the modification of polymer fiber surfaces by controlling the degree of etching and oxidation, which improves adhesion of initiators to the surface and facilitates subsequent conformal polymer grafting. The modified fiber surfaces render new functionalities to the surface, such as increasing hydrophilicity, attaching ligands or changing surface energy. The invention includes the modified polymer fibers produced by the process described herein.

摘要:
Compositions comprising extracts or isolated or purified compounds from plants of the genus Corydalis provide prevention and treatment of hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, hepatic steatosis, and metabolic syndrome. Corydalis compounds and their derivatives of natural and synthetic origins lower total cholesterol, LDL-cholesterol, and triglycerides and increase hepatic LDL receptor expression and activate AMP-activated protein kinase. Specific stereoisomers of Corydalis compounds with lipid lowering activity include 14R-(+)-corypalmine, 14R,13S-(+)-corydaline, 14R-(+)-tetrahydropalmatin, (+)-corlumidin, d-(+)-bicuculline, and (+)-egenine.

摘要:
A quantitative PCR method has been developed for the simultaneous detection and quantitation of an agent in samples of biologically derived materials. Unlike conventional quantitative PCR detection methods, this assay allows for the detection of viable agents.
