A landfill (24) has an impermeable liner (26) at its base and sides, and is capped at (28) by a multi-layer cap. The body of waste material (46) within the landfill (24) will undergo degradation. One byproduct will be leachate. Sediment (37) will develop at the bottom of the landfill (24) in the absence of any intervention. Extraction wells (38) extend from the surface (above the cap 28) down to the bottom of the landfill (24). A pump (54) allows leachate to be drawn from the waste material (46), through the extraction well (38). Leachate is extracted at a rate sufficient to create turbulence within the body of waste material (46). The turbulence serves to entrain sediment in the leachate for extraction of the entrained sediment with the leachate.

A hem insert is adapted for forming an inwardly or outwardly-turned cuff in a garment. The hem insert comprises an elongated flexible strip having opposing ends and opposing longitudinal straight edges. The hem insert is adapted for insertion into a sewn circumferential hem of the garment, and the hem subsequently folded by a wearer to form the cuff.

Structurally-glazed curtain wall or store front wall systems can include fire-rated glazing units coupled together by a framing system. The framing system include a plurality of uninsulated vertical mullions with a roll-formed steel profile. The roll-formed steel profile can form a first wall portion and two projecting wall portions that extend from the first wall portion in a generally perpendicular manner.

A mobile telecommunication device is provided with a table which includes rows of entries for use when roaming outside the home country. The entries are provided with an order of preference, indicated by the order of columns in the table. An entry may specify a subscriber identity (IMSI 1, IMSI 2 etc.) and a local network (Voda, Telfort etc.), or only a subscriber identity. When roaming, a device will seek to establish a satisfactory connection using the subscriber identity and local network specified by the first preference entry for the roaming country. If a satisfactory connection cannot be achieved, the next most preferred table entry is read to obtain an alternative selection of subscriber identity and local network. At least one group of entries (e.g. for Netherlands) specifies two different subscriber identities (IMSI 1, IMSI 2). Specifying multiple subscriber identities and multiple local networks in the group of entries improves reliability by allowing a satisfactory connection to be achieved from another local network, if a specified local network is not available and allows an alternative subscriber identity from an alternative home network to be used, in the event that a failure in a home network prevents the establishment of a connection.

A method for intelligently switching on/off an antenna of a mobile terminal and a corresponding mobile terminal can improve antenna performance. A method includes: detecting a current working frequency band and a surrounding environment of a terminal; and according to a preset correspondence among an antenna radiation unit, an environmental condition, and the current working frequency band, changing impedance characteristics of a parasitic unit radiator. Another method includes: detecting a current working frequency band of a terminal; and according to a preset correspondence between an antenna radiation unit and the current working frequency band, changing impedance characteristics of a parasitic unit radiator. Another method includes: detecting a current surrounding environment of a terminal; and according to a preset correspondence between an antenna radiation unit and an environmental condition, changing impedance characteristics of a parasitic unit radiator. The terminal includes: a detection unit, an antenna control unit, and an antenna radiation unit. With the above technical schemes, the antenna radiation unit is controlled according to the working frequency band and/or the environmental state of the terminal, so as to improve communication quality of an air interface of a wireless communications system.

Ultrasonic measurement apparatus 10 includes a transmitter 14 to transmit an ultrasonic signal 16 into an item 12. A receiver 18 receives echoes 20 from the item 12. The apparatus 10 measures the frequency spectrum of the echo 20 and makes a comparison with another frequency spectrum to extract information relating to a change in the item 12. For example, the item 12 may wear during use. A comparison of the frequency spectrum, with previous frequency spectra, allows changes of dimension of the item 12 to be identified. Changes in amplitudes of the frequency spectrum allow changes in roughness to be detected.

A method, device and system for controlling assistant information of user equipment are disclosed. The field of wireless communication technology is related, and the problem is solved that the system efficiency is reduced, for UE reports the assistant information inappropriately. The method includes: the user equipment acquiring a control parameter of assistant information configured by a network side; and the user equipment reporting the assistant information of the user equipment to the network side according to the control parameter of assistant information. The technical scheme provided in the example of the present invention is applied to a LTE system or a UMTS system, which implements that the network side controls the UE reporting the assistant information.

Two construction panels 10 have edges 12. Each edge 12 has a recess 14. That is, the recess 14 is open at the edge 12. The recess 14 receives, in use, an end of a connection arrangement indicated generally at 16. Each panel 10 further comprises an aperture extending from a face of the panel 10 to the recess 14 to receive, in use, a fixing pin 22 which retains the connection arrangement 16 in the recess 14. The connection arrangement 16 may include a turnbuckle arrangement formed by threaded members 36 each threaded to a common connector member 38 and each having an eye 42 to receive one of the fixings 22. Turning the common member 38 allows the threaded members 36 to be moved together or apart.

An overfeed roller assembly for use on a rotating drive shaft of a textile machine is adapted for adjusting downstream tension in a continuous moving length of yarn. The overfeed roller assembly comprises a base assembly designed for mounting on the drive shaft, and an annular yarn tension adjuster carried by the base assembly. The tension adjuster comprises opposing closely spaced yarn-contacting walls. The yarn- contacting walls define a shallow generally serpentine depression in the tension adjuster adapted for receiving the continuous moving length of yarn. Yarn tension downstream of the roller assembly is thereby reduced as the moving yarn meanders through the tension adjuster in frictional contact with the yarn-contacting walls of the serpentine depression.
