  • Patent number: 11976154
    Abstract: In at least one embodiment, a devolatilization vessel includes a first set of one or more devolatilization plates and a second set of one or more devolatilization plates. A first distributor is above the first set of one or more devolatilization plates and the second set of one or more devolatilization plates. A second distributor is above the second set of one or more devolatilization plates. In at least one embodiment, a process of forming a polymer includes forming a first polymer solution having a first viscosity and forming a second polymer solution having a second viscosity. The process includes flowing the first polymer solution and the second polymer solution to a devolatilization vessel. The process includes removing volatiles from the first polymer solution and the second polymer solution in the devolatilization vessel to form a devolatilized first polymer melt and a devolatilized second polymer melt.

  • Publication number: 20230271177
    Abstract: A lateral flow device for analysing a sample of liquid has a first lateral flow strip configured to respond to a first volume of sample and a second lateral flow strip configured to respond to a second volume of the sample, wherein the second volume is greater than the first volume. The lateral flow device comprises a first well configured to receive the first volume of the sample and a second well configured to receive the second volume of the sample. Each well has a flow restriction outlet located adjacent its lateral flow strip. The lateral flow device comprises a pre-actuation configuration and an actuated configuration.

  • Patent number: 11046960
    Abstract: A method of detecting gibberellins, for example in barley. Current methods of detecting gibberellins require dedicated equipment which makes it expensive and time consuming. A ligand bind assay for detecting gibberellins in which the above disadvantages could at least partially be overcome or alleviated is described. The ligand binding assay uses aptamers for the detection of gibberellins in barley seeds.

  • Publication number: 20050130322
    Abstract: Disclosed is an assay device to determine the presence of at least one analyte of interest in a liquid sample, the device comprising means for generating a first signal (the ‘test’ signal) which indicates the presence and/or amount of analyte of interest in the sample; and means for generating a second signal, the generation of which second signal indicates both (a) the test has been successfully conducted, and that (b) sufficient time has elapsed following contact of the assay device with the liquid sample for the test to be read and the first signal to have been properly generated.

  • Patent number: 6900336
    Abstract: This invention relates to compounds which are generally EP4 receptor agonists and which are represented by Formula I: wherein A is a —CH2—CH2—, or —CH?CH—; B is absent, an aryl, or heteroaryl group; R1 is alkyl, alkenyl, alkynyl, cycloalkylalkyl, heterocyclylalkyl, aryl, arylalkyl or heteroaryl, when B is aryl or heteroaryl and R3, R4, R5 and R6 are not simultaneously hydrogen, or R1 is heterocyclylalkyl, aryl, or heteroaryl when B is absent and R3, R4, R5 and R6 are simultaneously hydrogen; and the other substituents are as defined in the specification; or individual isomers, racemic or non-racemic mixtures of isomers, or pharmaceutically acceptable salts or solvates thereof. The invention further relates to pharmaceutical compositions containing such compounds, methods for their use as therapeutic agents, and methods of preparation thereof.

  • Publication number: 20030176998
    Abstract: A method and system are described for highly declarative specification of master-detail applications of relational databases, by end users who need not be trained in programming or in database administration. The method and system includes a notation in which end users can specify applications using their own English words and phrases, and by using place holders that are set out on indented lines to specify a master-detail hierarchy. The invention improves on the prior art by allowing a wider range of applications to be specified without programming, and without work by database administrators. The invention also improves on the prior art by automatically generating explanations showing what parts of the specification, and what supporting facts from the database, have been used in obtaining an answer to a question.

  • Publication number: 20030165242
    Abstract: A method and system are described to allow the encryption and decryption of a plaintext string of symbols, e.g. a paragraph of English text, using a key consisting in part of an executable computer program. The method and system is such that an attacker who seeks to recover the plaintext from the ciphertext, without knowing the key, can produce a very large number of decrypt attempts that are plausible, but unrelated in meaning to the original plaintext. However the attacker cannot know whether any one of the attempted decrypts is the correct original plaintext. A property of the method and system is that, if the same plaintext is encrypted twice using the same key, the respective ciphertexts are normally different, and normally have different lengths.
