A side wall is pasted with an electric heating plate and a thermal insulation cotton. A stirring paddle is arranged inside. An air inlet and an air outlet are respectively provided on a front and a rear wall. A discharging mechanism is located below. The electrical control cabinet separately controls the reaction conditions of each reaction chamber monomer. The present invention further relates to a use method thereof, which can realize the biodegradability evaluation in such three aspects as material degradation rate, disintegration rate and ecological non-toxicity test.

A testing method of thermal barrier coating (TBC) is for evaluating the presence or absence of damage to TBC formed on a bending part on which compression stress acts. The method includes a test piece that includes a pair of arm parts, a bending part arranged between the pair of arm parts, and a TBC layer on a bending surface of the bending part; attaching the test piece to a compression testing device after preparing the test piece; and applying compression stress to the test piece in a direction for bringing the pair of arm parts close together after attaching the test piece with the compression testing device. The pair of arm parts are arranged so as to separate from each other from base end portions toward front end portions of the arm parts. The bending part is arranged between the base end portions.

The invention relates to a method for processing an object using a material processing device that has a particle beam apparatus. The method comprises the following steps: determining a region of interest of the object on or in a first material region of the object, ablating material from a second material region adjoining the first material region by means of an ablation device, recognizing a geometric shape of the first material region, the geometric shape having a center, ablating material from a second portion of the first material region adjoining a first portion by means of a particle beam, the first portion having a first subregion and a second subregion, the region of interest being arranged in the first subregion, recognizing a further geometric shape of the first material region, the further geometric shape having a further center at a second position, relative positioning of the object such that the first position corresponds to the second position, and ablating material from the second subregion by means of the particle beam.

The present invention in general relates to a method of localization and structural characterization of peptides in a formaldehyde-fixed paraffin-embedded biological sample using matrix assisted ionization (such as in MALDI). Specifically, the invention relates to the combination of the development of a sample preparation protocol which does not require any enzymatic digestion nor antigen-retrieval steps, with highly sensitive mass spectrometry.

The specification describes devices, methods, and kits for mincing biological tissue. The method includes conforming biological tissue to having about uniform cross-sectional area planes along its length, and cutting the biological tissue. The conforming and cutting is performed cooperatively to control the size of the minced biological tissue. The device is suitable for use with the method.

An experimentation method for a type I stress intensity factor test considering frost heaving force periodic changes, steps being 1: preparing a specimen, waterjet cutting on the specimen to simulate a non-penetrating rock mass fracture; step 2: vacuum saturating the specimen; step 3: affixing a strain gauge in a non-elastic area at a tip of the specimen; step 4: placing the specimen into a rock mass (1) fracture frost heaving experiment box (5), pressurizing by a pressurizing apparatus (4) balloons on either side of the frost heaving experiment box (5), shutting a valve and removing a pipe, placing the frost heaving experiment box (5) holding the specimen into a water tank, allowing water to immerse the specimen; and step 5: placing the water tank and the frost heaving experiment box (5) holding the specimen together into a high-low temperature alternating experiment box (7) to start a freeze-thaw cycle experiment.

The present disclosure also relates to systems and methods for quality control in histology systems. In some embodiments, a method is provided that includes receiving a tissue block comprising a tissue sample embedded in an embedding material, imaging the tissue block to create a first imaging data of the tissue sample in a tissue section on the tissue block, removing the tissue section from the tissue block, the tissue section comprising a part of the tissue sample, imaging the tissue section to create a second imaging data of the tissue sample in the tissue section, and comparing the first imaging data to the second imaging data to confirm correspondence in the tissue sample in the first imaging data and the second imaging data based on one or more quality control parameters.

The present invention relates to devices, systems, and methods for cutting tissues. In some embodiments, the devices, systems, and methods of the invention relate to cutting tissues into fragments that find use in tissue culture and drug testing applications.

A double-cross composite fabric membrane biaxial tensile strength test piece is provided, including a core region and four cantilevers. The four cantilevers extend outwards around the core region and form a cross shape. Each cantilever is connected to the core region via an edge transition region. An end portion of the cantilever is a clamping section. The clamping section is provided with a clamping end rubber rod. The clamping end rubber rod is used for connecting to a clamp of a biaxial tensile testing machine. The clamping section is three-layered. The cantilever and the edge transition region are double-layered. The core region is single-layered. The edge transition region is in the shape of a quadrangle rounded at four corners. A manufacturing method of the test piece is also provided.
