RESEARCH ON MONITORING METHOD AND APPLICATION OF THE DYNAMIC CONTACT FORCE BETWEEN CATENARY AND PANTOGRAPH BASED ON STRAIN RESPONSE INVERSION TECHNOLOGY (MT)

In-situ monitoring of the dynamic contact force between catenary and pantograph is very important for the quality evaluation of pantograph catenary current collection.A monitoring method based on strain response was proposed to invert the value and position of the dynamic contact force between catenary and pantograph.The measurement principle, sens

Zika virus (ZIKV) is a flavivirus that has emerged as a global health threat after Room Freshner the 2015 outbreak in the Americas, where devastating congenital defects were documented.There are currently no vaccines to prevent ZIKV infections nor commercially available clinical diagnostic tests demonstrated to identify ZIKV without cross-reactive

GF ALL PURPOSE BAKING FLOUR In this paper we intend to map out some of the dominant values in print advertisements announcing different types of environmentally friendly products and services from energy (oil, electricity, etc.) and heavy industry corporations.We will analyse the qualities and values explicitly linked to ecological samples through

Abstract A spectrogram of Power Line Harmonic Radiation (PLHR) consists of a set of lines with frequency spacing corresponding exactly to 50 or 60 Hz.It is distinct from a spectrogram Breadmakers of Magnetospheric Line Radiation (MLR) where the lines are not equidistant and drift in frequency.PLHR and MLR propagate in the ionosphere and the magneto

Chronic constipation can lead to fecal impaction in the large bowel, which can cause pressure necrosis followed by perforation, known as a stercoral ulcer.In extensive posterior thoracolumbar surgery, a long operation time, large blood loss, and perioperative narcotic use may aggravate constipation.Moreover, sacral root palsy due to cauda equina sy
