Study on Detection of Psocids Annual Occurrence in Wheat Flour Warehouse in Guangzhou

open access: yesLiang you shipin ke-ji, 2020
Psocids occurrence was detected in flour warehouse from March-2017 to February-2018 by a corrugated board trap. The location of psocids and its relationship with temperature and humidity were analyzed by geostatistics contour mapping technology.

Collection of indirect excitons in a diamond-shaped electrostatic trap [PDF]

open access: yes, 2009
We report on the principle and realization of a new trap for excitons -- the diamond electrostatic trap -- which uses a single electrode to create a confining potential for excitons.

Trapped antihydrogen

open access: yesNature, 2010
Antimatter was first predicted in 1931, by Dirac. Work with high-energy antiparticles is now commonplace, and anti-electrons are used regularly in the medical technique of positron emission tomography scanning. Antihydrogen, the bound state of an antiproton and a positron, has been produced at low energies at CERN (the European Organization for Nuclear

A two species trap for chromium and rubidium atoms [PDF]

open access: yes, 2004
We realize a combined trap for bosonic chromium 52Cr and rubidium 87Rb atoms. First experiments focus on exploring a suitable loading scheme for the combined trap and on studies of new trap loss mechanisms originating from simultaneous trapping of two ...

Fast atomic transport without vibrational heating [PDF]

open access: yes, 2010
We use the dynamical invariants associated with the Hamiltonian of an atom in a one dimensional moving trap to inverse engineer the trap motion and perform fast atomic transport without final vibrational heating.

Assessment of vector/host contact: comparison of animal-baited traps and UV-light/suction trap for collecting Culicoides biting midges (Diptera: Ceratopogonidae), vectors of Orbiviruses [PDF]

open access: yes, 2016
BACKGROUND The emergence and massive spread of bluetongue in Western Europe during 2006-2008 had disastrous consequences for sheep and cattle production and confirmed the ability of Palaearctic Culicoides (Diptera: Ceratopogonidae) to transmit the virus.

Effects of Aprons on Pitfall Trap Catches of Carabid Beetles in Forests and Fields [PDF]

open access: yes, 2017
This study compared the efficacy of three types of pitfall traps in four forest and two field habitats. Two traps had aprons and one did not. The two apron traps were the same except for a gap between the trap and the plywood-apron, allowing captures ...

Effect of Subclinical and Overt Form of Rat Maternal Hypothyroidism on Offspring Endochondral Bone Formation

open access: yesActa Veterinaria, 2018
Maternal hypothyroidism in its overt form affects skeletal development of the offspring, but these data are not available for the subclinical form which is becoming very frequent among pregnant women.

The Malaise Trap: Its Utility and Potential for Sampling Insect Populations [PDF]

open access: yes, 2017
Slightly over three decades have elapsed since Malaise (1937) first published plans for the insect trap now bearing his name a stationary mesh tent with open sides, a central baffle, and a top-mounted collecting apparatus (Fig. 1).
