摘要:
Method for transmitting data from a controller to multiple stations in a wireless network, wherein said data comprises a first data set to be sent to a first station and a second data set to be sent to a second station, whereby the method comprises the following steps: generating a MAC frame comprising a MAC header and a payload, said payload comprising one or more packets, each packet being generated such that it comprises: a first control bits field including an identification (ID) of the first station, and data bits from the first data set; a second control bits field including an identification (ID) of the second station, and data bits from the second data set;
transmitting said generated MAC frame by said controller.
摘要:
A non-therapeutic method of accumulating a polymeric or high molecular weight molecular product within a bacterial microcompartment in bacterial cytoplasm, which method employs a recombinant bacteria which is genetically engineered to express a microcompartment containing an enzyme capable of converting a low molecular weight substrate into a polymeric or high molecular weight product, the method comprising the steps of: incubating the recombinant bacteria with the low-molecular weight substrate, or a precursor of the low molecular weight substrate which is capable of being metabolised to the substrate within the recombinant bacteria, such that the substrate or precursor is taken up by the bacteria, wherein the substrate enters the microcompartment and the enzyme within the microcompartment converts the substrate to a polymeric or high molecular weight molecular product, and wherein the polymeric or high molecular weight molecular product is accumulated within the microcompartment due to its size.

The method relates to a method of modulating quorum sensing in bacteria. Quorum sensing is inhibited using peptide hydrolases. This inhibition is used to prevent biofilm formation or to break down established biofilms and may also be used to downregulate the production of virulence determinants by pathogenic bacteria. The invention also relates to the use of peptide hydrolase inhibitors for the upregulation of quorum sensing in bacteria, resulting in the overproduction of proteins and the use of this system as an expression system.

A facial image generation system uses a first vector representation of a first facial image of a first individual having an age in a first age range, vector representations of a plurality of facial images of a first group of individuals having ages in the first age range, third vector representations of a plurality of facial images of a second group of individuals having ages in a second age range which does not overlap with the first age range and fourth vector representations of a plurality of facial images of a third group of individuals which are related to the individuals of the second group and of a different generation to the individuals of the second group. Data derived from the first, second, third and fourth vector representations is processed to generate an output vector representation which comprises a vector representation of an estimate of the facial image of the first individual in the second age range. This system uses samples of facial images of the starting age (the first age range) and the target age (the second age range) in order to model the ageing process on the vector representations of a given facial image. In addition, samples of facial images are used to derive a relationship between the facial images of different generations of the same family. This relationship can then be used to ensure that an ageing algorithm (to an older or to a younger age) can be applied which is consistent both with a general change in appearance between the starting age and the target age, but also to provide consistency of the estimated facial image with other family members of the first individual.

The present invention relates to a method of treating a disorder mediated by soluble adenylyl cyclase in a subject. The method involves administering to a subject an effective amount of a compound disclosed herein that modulates soluble adenylyl cyclase, under conditions effective to treat the disorder mediated by soluble adenylyl cyclase. The present invention also relates to a method of treating a disorder mediated by soluble adenylyl cyclase in a subject, where the disorder is selected from the group consisting of: learning or memory disorders, malaria, fungal infection, spinal cord injury, Alzheimer's disease, amyotrophic lateral sclerosis, and peripheral neuropathy. The method involves modulating soluble adenylyl cyclase in the subject. Another aspect of the present invention relates to a method of modulating soluble adenylyl cyclase. The method involves contacting eukaryotic cells with a compound that modulates soluble adenylyl cyclase, under conditions effective to modulate soluble adenylyl cyclase.
摘要:
A spectral interferometry apparatus and method is provided to supply unambiguous profiles (A - scans free of mirror terms) of the reflectivity versus optical path difference and make difference between the positive and negative optical path difference or provide output in a selected interval of optical path differences. The apparatus comprises object optics that transfer a beam from an optical source to a target object (55) to produce an object beam and reference optics that produce a reference beam. Displacing means (57) are provided to produce a gap (g) between the object beam (41’) and the reference beam (42’). Optical spectrum dispersing means (7) such as a grating or a prism receive the two relatively displaced beams, and disperse their spectral content onto a reading element such as a CCD. The combination of the displacing means and the optical spectrum dispersing means creates an intrinsic optical delay between the wavetrains of the object beam and the reference beam which can be used with the optical path difference in the interferometer to generate a channelled spectrum for the optical path difference in the interferometer on the reading element.
摘要:
A process for the microbial degradation of waste characterised in that it comprises determining the significant constituent(s) of a waste, providing one or more microorganisms able at least partially to degrade and/or biotransform and/or mineralise each determined constituent of the waste, optionally providing one or more other microorganisms capable of furthering mineralisation of biotransformation or partial degradation product(s), growing one or more mixed cultures of at least some of the microorganisms on a synthetic mixture of at least some of the determined constituents of the waste and utilising the adapted population of microorganisms substantially to mineralise the actual waste is disclosed. The present process is generally applicable, but a particular area of use is in the treatment of waste from acrylonitrile production.
