The paper considers the analysis of the market for garden equipment. The authors consider some information on garden equipment failures, using an example of Husqvarna trimmers. They also assess a possibility of using additive technologies to manufacture sliding bearings for mechanical drives of garden equipment. For testing the physical and mechanical properties, a batch of samples was prepared by means of 3D printing using FDM (FFF) technology. According to the ASTM D638-14 standard, samples were prepared on a PICASO 3D Desingner X Pro 3D printer. Samples were made of ABS-plastic and PA12 with diff erent degrees of fi lling: 20, 50 and 100%. It is noted that the destruction pattern of samples made of diff erent materials is signifi cantly diff erent. Samples made from ABS plastics are more fragile than samples made from PA12. According to the test results, PA12 with 100% fi lling have shown the best results, which makes them suitable for use in the manufacture of slide bearings by means of 3D printing.
Proton beam characterisation of a prototype thin-tile plastic scintillator detector with SiPM readout for use in fastneutron tracker R Preston, J Jakubek, D Prokopovich et al. ABSTRACT: The paper analyses the factors affecting the detection efficiency and the spatial resolution of the luminescent detectors intended for fast neutron imaging. An analytical approach has been used for this purpose. A design of the large area detector based on the application of a matrix screen and a set of crossed wavelength shifting fibers (WLS) for reading out the scintillation signal has been suggested. The spatial resolution of the detector depends on the cross section of the matrix cell. The detection efficiency of the detector is sufficiently high and can amount to about 25% for the screen made of polyvinyl toluene in the case of 14 MeV neutrons.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
