The invention discloses a Hadoop-based mass stream data storage and query method and a Hadoop-based mass stream data storage and query system. The method comprises the following steps of: constructing a segmented column cluster type storage structure; sequentially storing stream data as column cluster records, compressing the column cluster records from front to back to obtain compressed data pages, writing each compressed data page into a piece of column cluster data, and simultaneously additionally writing the page outline information of the compressed data pages into the tail ends of the column cluster data to obtain an integrated data segment; and in the process of executing query statements, constructing a scan table according to filtering restraints by utilizing the page outline information at the tail ends of data segments to quickly filter the data.

A lighting system, a reflector, light sources and a light control member are sequentially disposed from a light incident side to a light outgoing side. Preferably used for large displays requiring high uniformity, this invention eliminates lamp image and removes the necessity to do light source repositioning, while enabling luminance in the exit plane to achieve excellent luminosity and uniformity. This invention achieves total transmittance of more than 50% when light is incident on the normal direction of the incident plane at a predetermined angle α and achieves 1.05-3 times more total transmittance than when the light is normally incident. This is achieved by using a light control member such as the light diffusion plate described herein, which is conformed to obtain required luminosity and uniformity by controlling the ratio between total transmittance in the positions of greater transmittance and the total transmittance in the positions of lesser transmittance.

Ligase detection reaction is utilized to distinguish minority template in the presence of an excess of normal template with a thermostable ligase. This process can be carried out with a mutant ligase, thermostable ligase, or a modified oligonucleotide probe. This procedure is particularly useful for the detection of cancer-associated mutations. It has the advantage of providing a quantitative measure of the amount or ratio of minority template.

The invention discloses a technique method for producing high-concentration nitric phosphate, which comprises the following steps of: adding nitric acid into phosphorus ore for acidolysis, depositing and separating acid non-soluble substance, freezing and crystallizing calcium nitrate, filtering the calcium nitrate, neutralizing the mother liquid, vaporization, pelleting and drying. The invention is characterized in that: a step of thoroughly removing the calcium of the mother liquid is arranged between the steps of filtering the calcium nitrate, and neutralizing the mother liquid. The steps comprise the following steps of: I) thoroughly removing the calcium of the mother liquid and adding sulfuric acid or ammonium sulfate; the calcium ions and the sulfate ions in the mother liquid generate dihydrate calcium sulfate crystal; II) the grading processing of reaction slurry: employing a grading device to carry out grading processing to the reaction slurry; returning the reaction slurry provided with small grain calcium sulfate to the mother liquid for thoroughly removing the calcium, and feeding the reaction slurry provided with large grain calcium sulfate to the calcium sulfate for filtering; and III) filtering and washing the filtering reaction slurry of calcium sulfate by a filter, feeding the primary filtrate and the primary lavage fluid into the working procedure of neutralizing, and returning the secondary lavage fluid to the filter. The invention has the advantage of using middle-low quality phosphorite to prepare the high-concentration nitric phosphate.

The invention relates to an apparatus for simultaneously injecting fluids into a plurality of samples of porous media, comprising: a plurality of holders for the samples of porous media, each holder comprising a sleeve and first and second platens, the first platen having an inlet for an injection fluid and the second platen having an outlet for a produced fluid, and the samples of porous media being arranged, in use, in each of the holders such that the first platen and second platen of each holder contact a first and second end of the sample of porous medium respectively, the inlet of each first platen being in fluid communication with an injection line for injecting fluid into the sample of porous medium arranged in the holder, the outlet of each second platen being in fluid communication with a dedicated effluent line for removing fluid produced from the sample of porous medium arranged in the holder, on-line and/or off-line analytical means for analyzing the fluids injected into each of the samples of porous media, on-line and/or off-line means for analyzing the fluids removed from each of the samples of porous media. A method of simultaneously injecting injection fluid into the samples of porous media is also provided.

A thermally bonded filtration media that can be used in high temperature conditions in the absence of any loss of fiber through thermal effects or mechanical impact on the fiber components is disclosed. The filter media can be manufactured and used in a filter unit or structure, can be placed in a stream of removable fluid, and can remove a particulate load from the mobile stream at an increased temperature range. The combination of bi-component fiber, other filter media fiber, and other filtration additives provides an improved filtration media having unique properties in high temperature, high performance applications.

A switchable view angle control device includes an electrically switchable zenithal bistable liquid crystal display view angle control liquid crystal device (ZBD view angle control LCD) that is operable in a first state and a second state; a front polarizer located on a viewing side of the switchable ZBD view angle control LCD; and a polarized light source located on a non-viewing side of the switchable ZBD view angle control LCD that emits light that is polarized in a first direction. When the switchable ZBD view angle control LCD in the first state, the view angle control device operates in a narrow angle view mode in which the polarization of the light from the polarized light source is changed by the switchable ZBD view angle control LCD to be polarized in a second direction that is at least partially absorbed by the front polarizer, and on-axis light passes through the switchable ZBD view angle control LCD and the front polarizer. When the switchable ZBD view angle control LCD is in the second state, the view angle control device operates in a wide angle view mode in which the polarization state of the light from the polarized light source is not changed by the switchable ZBD view angle control LCD and passes through the front polarizer.

Compounds having quinone and quinone analogs useful for pharmaceutical preparations have now been found which inhibit cysteine proteases, in particular, caspases and 3C-cysteine proteases. The cysteine protease inhibitors of the present invention can be identified by their mode of action in disrupting the ability of cysteine proteases and, in particular, caspases to cleave a peptide chain. These compounds are useful in inhibiting cysteine protease or cysteine protease-like proteins and for treating infections diseases or physiopathological diseases or disorders attributed to the presence of excessive or insufficient levels of cysteine proteases.

The invention discloses a method for efficiently separating single antigen-specific B lymphocyte from spleen cells. High-throughput rapid screening of single antigen-specific B lymphocyte is realizedby negative screening adopting multiple lymphocyte surface marker antibodies, establishment of a rapid fluorescence marked antigen substance method and high-specificity screening by use of a fluorescence marked antigen substance, and the positive rate of the finally obtained antibody-specific B lymphocyte is increased from less than 5% in a traditional hybridoma method to 30%. Therefore, the scheme can shorten monoclonal antibody development time to a great extent and greatly increase the number and diversity of obtained monoclonal antibodies.
