The shearer is under complex impact when it works.and it makes the shearer cutting unit vibrate,which increase the burden of the spiral drum and rocker arm shell.Besides,it would bring bad effects to the shear performance of the shearer.In order to study its study the working stability,the vibration mathematical opi the color that keeps on giving e

The documentation of anticoagulant rodenticides (AR) in nontarget species has centered around wildlife that inhabit urban or agricultural settings.However, recent studies in California have shown that AR use in remote forest settings has escalated and has exposed and killed forest carnivores.Anticoagulant rodenticides have been documented as physio

This paper presents a polarization reconfigurable differential circularly polarized (PRDCP) antenna with wide impedance and axial ratio (AR) bandwidth for right-hand circular polarization (RHCP) or left-hand circular polarization (LHCP).The antenna is composed of a bandwidth-improved radiator and a reconfigurable differential-to-single-ended sequen

Heritage Building Information Modelling (HBIM) can be a valuable tool for the efficient management of cultural heritage.Adopting Building Information Modelling (BIM) for heritage architecture requires investing in training for modelling as-found elements, establishing standards for modelling, and developing accessible libraries of parametric assets

Transitive inference (TI) is the ability to infer unknown relationships from previous information.To test TI in non-human animals, transitive responding has been examined in a TI task where iphone 13 price dallas non-adjacent pairs were presented after premise pair training.Some mammals, birds and paper wasps can pass TI tasks.Although previous stu
