Cluster headache is generally considered to be a primary headache; secondary cluster-like headache is quite rare, while cluster-like headache secondary to meningioma is even rarer.Here, we describe an unusual case with cluster-like headache 2.5 years after sphenoid ridge meningioma surgery.The cluster-like headache and meningioma were on the same s
Sand filter is frequentlyused to treat contaminated water.Channel filter system is a modification of sand filter where the channel is shaped thus the land requirement could be minimized, water is flowed horizontallyfrom intial tank to finaltank through sand filter.Employing the channel filter to treat domestic wastewateris capable of reducing E.Col
With the increasing interest in autonomous transport, machine vision and remote sensing, several three-dimensional time-of-flight (ToF) imaging technologies that can recover object's fine Grapeseed details have been presented.Single-pixel imaging provides an alternative to ToF photon-counting imaging with a scanned laser spot.In this work, w
