High Efficiency Cyclotron Trap Assisted Positron Moderator
Instruments, 2018 We report on the realisation of a cyclotron trap assisted positron tungsten moderator for the conversion of positrons with a broad keV–few MeV energy spectrum to a mono-energetic eV beam with an efficiency of 1.8(2)% defined as the ratio of the ...

Design and Performance Evaluation of Asymmetric Hyperboloid Linear Ion Trap [PDF]
Zhipu Xuebao, 2021 Hyperbolic electrode linear ion trap is a good choice as the mass analyzer of miniaturized ion trap mass spectrometer for the reason that it has a compact size and excellent performance. However, ions are ejected from both opposite directions along the x-

Determining The Critical Degree of Reservoir Lifetime for The Saguling Reservoir Based on The Sediment Inflow Simulation [PDF]
Jurnal Teknik Sipil, 2010 This study aims to find out the relationship between the critical degree of reservoir lifetime and sediment inflow. The critical degree of reservoir lifetime is defined as the ratio between the designated lifetime of the reservoir and its effective ...

A Study of the Sedimentation and Storage Capacity Depletion of a Reservoir
Slovak Journal of Civil Engineering, 2023 Theoretical and empirical equations have previously been proposed to compute the sediment trap efficiency of a reservoir. The empirical equations were developed by analyzing a limited amount of field data for reservoirs in selected areas; thus, their ...

Evaluation of sediment barriers in relation to the trap of soil particles
Soil and Water Research, 2022 Water erosion and the subsequent sediment deposits can cause a number of environmental problems. The damage can be mitigated by means of sediment barriers. Their use is most often associated with the construction or protection of transport infrastructure.

Efficiency of antlion trap construction [PDF]
Journal of Experimental Biology, 2006 SUMMARYAssessing the architectural optimality of animal constructions is in most cases extremely difficult, but is feasible for antlion larvae, which dig simple pits in sand to catch ants. Slope angle, conicity and the distance between the head and the trap bottom, known as off-centring, were measured using a precise scanning device.

Flight behaviour of malaria mosquitoes around odour-baited traps: capture and escape dynamics [PDF]
Royal Society Open Science, 2018 Host-seeking mosquitoes rely on a range of sensory cues to find and approach blood hosts, as well as to avoid host detection. By using odour blends and visual cues that attract anthropophilic mosquitoes, odour-baited traps have been developed to monitor ...

Performance analysis of rectangular SIT (sediment invert trap) for stormwater drainage system
Journal of Hydrology and Hydromechanics, 2022 Deposition of solid particles in the stormwater sewers reduces the discharging capacity, causing inundation. A sediment invert trap (SIT) is an option that can be installed at the bottom of the stormwater sewer drain to intercept the flowing solid ...
