摘要:
Tc-99m products containing at least one compound of the formula I ##STR1## in which R is a methyl, ethyl or propyl group and n represents a number from 1 to 6, or the physiologically tolerated salts thereof, are suitable for use in bone scintigraphy, especially for locating bone tumors.
摘要:
The invention is a reboiler-condenser which increases the efficiency of heat transfer between boiling and condensing fluids, such as oxygen and nitrogen in air separation or similar cryogenic applications. The exchanger is built up from individual plates, the opposite sides of which have enhanced condensing and boiling surfaces. The condensing channels are inclined slightly downward so that condensate can be removed at many elevations in the exchanger.
摘要:
One aspect of the invention relates to a hydrogel comprising a non-natural polymer comprising a plurality of pendant nucleophilic groups and a crosslinker comprising at least two pendant electrophilic groups. Another aspect of the invention relates to a hydrogel comprising a non-natural polymer comprising a plurality of pendant electrophilic groups and a crosslinker comprising at least two pendant nucleophilic groups. Yet another aspect of the invention relates to a method for reducing lung volume in a patient comprising the step of administering a hydrogel composition as described herein. Further, hydrogels of the invention may be used to achieve pleurodesis, seal brochopleural fistulas, seal an air leak in a lung, achieve hemostasis, tissue sealing (e.g., blood vessels, internal organs), or any combination thereof. In certain embodiments, the compositions and methods described herein are intended for use in the treatment of patients with emphysema.

One aspect of the invention relates to a hydrogel comprising a polymer comprising a plurality of pendent hydroxyl groups, a crosslinker, and a sclerosing agent. Another aspect of the invention relates to a method for reducing lung volume in a patient comprising the steps of advancing into a region of a patient's lung via said patient's trachea a multi-lumen catheter lumen through a bronchoscope; and co-administering, through the multi-lumen catheter, a first mixture comprising a first amount of a polymer containing a plurality of pendent hydroxyl groups; a second mixture comprising a second amount of a crosslinker; and a third mixture comprising a third amount of a sclerosing agent; thereby forming a hydrogel in said region. In certain embodiments, the compositions and methods described herein are intended for use in the treatment of patients with emphysema of the lung.
摘要:
A method and apparatus for operating a meter uniquely associated with a physical location are provided. The method includes monitoring a communication channel for a message from a remote device and identifying an initial message directed to the meter uniquely associated with the physical location, establishing a communication session with a data manager in response to the initial message from the remote device, receiving configuration information from the data manager, the configuration information associated with operation of the meter and uniquely associated with the physical location of the meter, and transmitting meter operating data to the data manager, wherein the meter is self-powered.
摘要:
A meter apparatus and method of operating a removable meter apparatus are described. The meter apparatus includes a tag associated with unique tag identification information and configured to be permanently affixed to a location housing at a unique physical location, and includes a removable meter unit configured to mate with the location housing and receive the tag identification from the tag and report the tag identification to a data manager configured to associate an identifier of the removable meter unit with the tag identification and unique physical location, and associate configuration information for the physical location with the removable meter unit and the tag identification. The unique physical location can comprise a single-space parking location.
摘要:
A single bay parking meter device is provided which accepts payment by means of a credit or debit card, an electronic purse, or coins. The device has a power supply unit, a solar power charging arrangement and power management, such that it does not need power supply cables to be installed for each meter. The parking meter device also transmits financial data to a financial institution in a wireless manner, also to avoid the need for cabling. The parking meter device is receivable in the base of a conventional single bay parking meter, such that the new parking meter device may be retrofitted to existing coin operated installed single bay parking meters, using a new cover that is also engageable with the conventional housing base.
摘要:
A separate removable and replaceable coin validation unit for use in a coin-operated device has a housing and clip formations by means of which the housing is releasably held in a cavity in the coin-operated device. The coin validation unit is electrically operable and has electrical connectors which connect with complementary connectors in the cavity. The coin operated device is particularly a single bay parking meter.
