摘要:
Halogenated alkyl substituted phenols may be dealkylated by treating a compound such as 5-t-butyl-2-fluorophenol with a diealkylation catalyst such as an acid acting compound at dealkylation conditions whereby the t-butyl substituent is removed and the resulting compound comprising 2-fluorophenol is recovered.
摘要:
Alkyl substituted 1,2-halofluorinated aromatic compounds may be subjected to hydrolysis to form an alkyl substituted o-fluorophenol by treating said compound with water in the presence of a relatively mildly basic compound such as the salt of a strong base and a weak acid at hydrolysis conditions to form the desired compound.
摘要:
Prenyl chloride (1-chloro-3-methylbutene-2) may be synthesized in increased yields by reacting isoprene with hydrochloric acid in the presence of sodium chloride. In addition, the yield may also be advantageously increased by utilizing a modified method of operation in which the distillation heads and tails fractions which are obtained from the process are recycled to the reaction zone.
摘要:
This invention provides a method for treating a human subject afflicted with multiple sclerosis or a single clinical attack consistent with multiple sclerosis with a pharmaceutical composition comprising glatiramer acetate and a pharmaceutically acceptable carrier, comprising the steps of 1) identifying whether the human subject is a predicted responder to glatiramer acetate by determining the genotype of the subject at one or more single nucleotide polymorphisms (SNPs) selected from the group consisting of the SNPs in Group 1; and 2) administering the pharmaceutical composition comprising glatiramer acetate and a pharmaceutically acceptable carrier to the subject only if the subject is identified as a predicted responder to glatiramer acetate.

Embodiments of a food container including a media player are provided. In some embodiments, the food container has an exterior, and the food container comprises at least one compartment sized and dimensioned to accommodate food. Additionally, the food container includes a media player configured to play media content. The container and/or media player includes at least one device that serves as an input device to select media content in the media player of for later play and activation device to activate the play of the selected media content. In another embodiment the container and/or media player includes two devices, one to select media content and another to activate play of the selected media content. The media content can be, for example, a message from a parent or other meal maker to a child for later play by the child during the day.
摘要:
High throughput channel operation in a mesh wireless local area network (WLAN) is disclosed. A mesh network comprises a plurality of mesh points and a network management entity (NME). The NME is configured to retrieve capability and configuration data from the mesh points. The NME configures at least one mesh point with respect to IEEE 802.11n channelization and legacy protection mode based on the capability and configuration data.
摘要:
An aggregated medium access control (MAC) frame for use with multiple transmission rates in a wireless communication system includes an aggregated header; at least one MAC protocol data unit (MPDU), the MPDUs being grouped together in the frame by transmission rate of the MPDU; and a separating sequence between each rate group. The aggregated header includes a count field to indicate a number of rates that have been aggregated in the frame and an information group for each rate that has been aggregated in the frame.
摘要:
A wireless local area network (WLAN) includes at least one high throughput-enabled access point (AP) and at least one high throughput-enabled station (STA). A STA and a target AP communicate high throughput-related information and the STA performs a basic service set (BSS) transition to the target AP based on the high throughput-related information. The high throughput-related information may be included in an IEEE 802.11r, 802.11k, or 802.11v signaling message. The STA may send measurement reports for an extended range and a normal range of an AP separately, or may send a combined measurement report for an extended range and a normal range of an AP. A network management entity may obtain current status information of the STA and the AP regarding high throughput capabilities, features and parameters and selectively enable and disable at least one of the high throughput capabilities, features and parameters of the STA and the AP.
摘要:
In accordance with a preferred embodiment, the present invention comprises a method for using the remaining TxOP time by the peer node to forward traffic to a different destination, a method for using the remaining TxOP time by the original node to send traffic to a different destination, a method for using the remaining TxOP time by a neighbor to send traffic to the original node, a method for using the remaining TxOP time by a neighbor to send traffic to another node, a method to signal the reuse rules of the remaining TxOP time, and a method to efficiently relinquish/truncate a TxOP to reset the NAV for the neighborhood.
摘要:
A unit dosage form suitable for once daily administration to a human comprising a physiologically effective amount of at least one hormone selected from the group consisting of steroidal estrogen, estradiol, estrone, medroxyprogesterone, norethindrone, norethisterone, progestin, norgestrel, and progesterone, and at least one carotenoid wherein the carotenoid is in an amount effective to prevent the adverse effects which may result from the administration of the hormone.
