Abstract:
The present invention relates to non-pathogenic strains of HIV-1 and to components, parts, fragments and derivatives thereof and to genetic sequences derived therefrom and their use in the development of diagnostic and therapeutic compositions for the treatment and prophylaxis of AIDS and AIDS-related disorders. The present invention also relates to a method for attenuating pathogenic strains of HIV-1 by mutagenizing particular regions of the HIV-1 genome.
Abstract:
A mechanical bladder pump is provided for collecting fluid samples from a well. The pump includes an outer tubular member having a longitudinal bore, and an inner tubular member arranged within the bore of the outer tubular member. The inner and outer tubular members are connected at their lower ends to a compressible bladder, and are arranged for oscillating movement relative to each other to expand and compress the bladder. The lower end of the bladder is open to an inlet passage, and the upper end of the bladder is open to an outlet passage. First and second check valves are provided to control the flow of fluid through the bladder during operation of the pump. A return spring is used to store energy during a tension stroke of the inner tubular member and to release energy during a compression stroke thereof. The pump provides highly representative samples of groundwater.
Abstract:
An antenna arrangement is provided with a phase lock loop so that the phase of microwave energy radiated by an antenna element can be precisely controlled. The phase lock loop provides compensation for phase errors introduced in the feed to the antenna element and includes a controllable local oscillator. In practice, a large number of individual antenna channels could be provided, each having its own phase lock loop, so that together a directional microwave beam could be radiated. Such a requirement can exist in connection with pulsed radars.
Abstract:
Embodiments may comprise a personal cargo device. According to some embodiments a personal cargo device may include an elongate strip defining a band, and the band may include fastening means at either end so that the ends may be joined. Furthermore, the bands may have at least one lateral fastening means disposed along the length of the band which is adapted to engage a hanging cargo member. A hanging cargo member may be so dimensioned as to substantially cover and/or protect a thigh of a wearer, and may include one or more integrated storage means. An integrated storage means may be closable with a closure flap, which may be removable from an embodiment.
Abstract:
The invention provides a method of handover from an active network to a selected one of a plurality of potential other networks. In addition to the overall solution, the solution proposed has several individual aspects. All subsidiary aspects are related to the common problem mentioned above and sharing the underlying common solution concept of implementing a system in which selective handover is possible and in which a list of available other networks provided by an active network can be handled and selection made by a terminal, so that neighbor cell information can be transmitted based on expressed terminal preferences.
Abstract:
There is disclosed a method to synthesize microporous crystalline material comprising a metal containing chabazite having a crystal size greater than 0.5 microns and a silica-to-alumina ratio (SAR) between 5 and 15, wherein the method is carried out without the use of an organic structural directing agent and without requiring calcination. There is also disclosed a large crystal organic free chabazite made according to the disclosed method. In addition, there are disclosed methods of using the disclosed crystalline material, such as in the selective catalytic reduction of NOx in exhaust gases.
Abstract:
The present invention is directed to a lubricating oil composition, a diesel engine comprising a lubricating oil composition, and a method of lubricating a diesel engine provided with an exhaust gas recirculation system, comprising lubricating said engine with a lubricating oil composition comprising an oil of lubricating viscosity, and a polymeric N-dispersant booster.
Abstract:
Methods and apparatus are disclosed for combining advertising messages with short message service (SMS) messages in a wireless communications system. A signaling message processing and routing node transmits and receives short message service (SMS) data packets via a communications network. The routing node includes an SMS message processing module that determines whether an SMS message should be modified to include advertisements. SMS messages, whether modified or left unmodified, are forwarded to a destination mobile communications device. The SMS message processing module applies rules to match selected advertisements with the SMS message. The determination of whether to modify the SMS message to include a selected advertisement is based on a variety of considerations including: the content and format of the SMS message; the content and format of the advertisements; the communications and display characteristics of the destination mobile communications device; and the limitations of the channel used to communicate the message to the destination mobile communications device.
Abstract:
Compositions and methods for decontaminating surfaces are disclosed. More specifically, compositions and methods for decontamination using a composition capable of generating a long lasting foam. Compositions may include a surfactant and gelatin and have a pH of less than about 6. Such compositions may further include affinity shifting chemicals. Methods may include decontaminating a contaminated surface with a composition or a foam that may include a surfactant and gelatin and have a pH of less than about 6.
