摘要:
An air quality test unit for attachment to a vent of a HVAC system with air flow there through. The air quality test unit contains at least two substrate panels arranged in a v-shape form wherein at least one panel includes a sticky surface or a collection container. The air quality test unit is attachable to the vent by one or more clips. The sticky surfaces or collection container of the substrate panels capture airborne substances and contaminants emanating from the air flow of the HVAC system vent. A culture growth medium may be disposed in the collection container or on the sticky surface. The air quality test unit kit provides a user with an air quality test unit and process for shipping the unit to the laboratory for analysis.
摘要:
A method for measuring a dynamic viscoelasticity of a particulate material uses, as a sample to be subjected to the dynamic viscoelasticity measurement, a sheet-shaped test piece in which the particulate material to be measured is attached to an adhesion layer formed on a heat-resistant sheet base material. With regard to the measurement conditions of the dynamic viscoelasticity measurement, the measurement temperature is within a predetermined temperature range of from −150 to 300° C., the heating rate is a constant rate ranging from 0.01 to 100° C./minute, the measurement frequency is a constant frequency ranging from 0.01 to 100 Hz, and a sine wave control tensile mode is employed. When the particulate material is attached to the adhesion layer, the particulate material crushed in advance is sprinkled on one side of the adhesion layer and then the particulate material-sprinkled surface is squeegeed and/or air-blown.

摘要:
A film with a tissue section is placed with the tissue section downward on a microscope slide and the microscope slide positioned in the object plane of an inverse microscope; where an adhesive tape is arranged, with a bonding agent downward, above the film and therefore above the tissue section; wherein the next step, tissue to be isolated is excised by a focused laser beam, which also divides the film; whereupon removal of the adhesive tape from the microscope, the excised tissue pieces adhere to the adhesive tape, and the remnant of the film and of the tissue section remains adhering to the microscope slide.

Systems and methods for automated laser microdissection are disclosed. In one variation, targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition to the location of an interior of a cut path. In another variation, a sample of biological material is mounted onto a polymer membrane which is then placed onto a substrate. Targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition with the targeted biological material on the side of the biological material. In yet another variation, a sample of biological material is mounted onto a polymer membrane which is then inverted onto a substrate. Targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition with the targeted biological material on the side of the polymer membrane. Then, an UV laser cuts along a cut path around the targeted portions of biological material in a closed cut path or a substantially closed cut path defining an interior and an exterior portion of the tissue sample. In a substantially closed cut path, bridges are left spanning the interior of the cut path and the exterior of the cut path. An IR laser activates at least a portion of the transfer film such that the transfer film in the vicinity of targeted portion adheres to the biological material interior to the cut path. The transfer film is then removed separating the targeted portions of biological material which are adhered to the transfer film from the remaining portion of the tissue sample.
摘要:
A method for measuring of histamine in an epidermis comprising applying an adhesive article to an epithelium of a mammal; allowing for adherence of epithelial cells to the adhesive article; removing the adhesive article from the epithelium of the mammal; preparing the adhesive article using standard laboratory methods for extraction; extracting histamine from the epithelial cells adhered to said adhesive article; measuring histamine from the epithelial cells adhered to said adhesive article; determining the amount of histamine in the epithelial cells as compared to a baseline sample. Further, a method of objectively measuring the perception of itch in mammals and wherein there is a reduction in histamine from a baseline level which is directly proportional to a reduction in an itch perception.
摘要:
Disclosed is a monitoring system for collecting and/or transdermally rediffusing air containing environmental contaminants. The inventive monitoring system generally includes at least one diffusion collector and/or an equilibrium diffuser. The diffusion collector is provided with at least three layers, i.e. an adhesive layer that is in direct contact with the skin of a living being, a barrier layer, and a collecting layer on the exterior face of the monitoring system. The equilibrium diffuser includes an adhesive layer and a collecting layer. The collecting layers and the adhesive layers of the two components of the monitoring system are preferably made of the same material and have the same dimensions.

The container comprises a cylindrical member 20 which constitutes the side wall member, a bottom member 30 which is in contact with the bottom plane of the cylindrical member 20 and which constitutes the bottom part, and an engaged fixing part 35 for engaging the cylindrical member 20 with the bottom member 30; the cylindrical member 20 and the bottom member 30 sandwiches the carrier tape T from one side T1 of the carrier tape T and from the other side T2 of the carrier tape T, respectively, such that one of the plural thin section samples P1 may be disposed inside the cylindrical member 20. Accordingly, without cutting a sequence of tapes carrying thereon the thin section samples of biomedical tissues, each of the thin section samples of the biomedical tissues can be individually processed with different chemicals depending on the required observation for various types of biomedical tissues.
摘要:
Airborne particles are impacted on a collection surface, analyzed, and then the collection surface is regenerated. Thus, the same collection surface can be used in numerous cycles. The analysis can be focused on one or more properties of interest, such as the concentration of airborne biologicals. Sensors based on regenerative collection surfaces may be incorporated in many networks for applications such as building automation.
