The fracture development of the overlying strata after coal mining is an important guarantee of efficient gas drainage.In order to explore the fracture evolution characteristics close to a mined coal seam group, the F15.16-24130 working face in the Pingdingshan No.10 coal mine was taken as the research background.The FLAC3D numerical simulation sof
The different ecological components of fragile ecosystems in the Pantanos de Villa Wildlife Refuge are naturally affected by fluctuations in Photo-Video climate variability, mainly due to climatological elements.The impact of vegetation by climatic variability was determined based on the normalized difference vegetation index (NDVI) with climatic d
A simple, thin, flexible mantle cloak for conducting Crank Link rods based on scattering cancellation is analyzed, designed and experimentally realized.We show strong scattering suppression at all angles of incidence, for both far-field plane-wave and near-field Gaussian excitations.The required effective shunt surface impedance is realized by a su
Since antiquity, the interaction of brain and heart has inspired physicians and philosophers.Today, our knowledge has vastly improved, but the exact way of their interaction still holds SHELF many secrets to reveal.The interaction between brain and heart merits particular attention in the aftermath of a sudden injury to the brain-like acute The Fas
Covid-19 (SARS-CoV-2) is a new coronavirus.Since the declaration of a global pandemic, a lot has been learnt about its SHELF spread, disease pattern, diagnosis and management.The lungs remain the prime organs to incur serious insult and when lung complications embark, significant morbidity and mortality is observed.Predominantly, patchy and periphe
