In electronic topological Dirac semimetals (DSMs) the conduction and valence bands touch at discrete points in the Brillouin zone and formDirac cones. They are robust against spin–orbit interaction (SOI) and protected by crystal symmetries. They can be driven to different topological phases by breaking the symmetries. In the low-temperature quantummagnetic systems themagnon dispersions have sim...

In this study, a medicinal plant, Galla rhois (GR), was examined and screened for its anti-Helicobacter pylori activity. Galla rhois was extracted with 70% ethanol. Inhibitory zone tests, as in vitro assays, and an in vivo study using a Mongolian gerbil (Meriones unguiculatus) model were performed. The safety of the GR extract was then evaluated in an animal study. The Galla rhois extract demon...

Roads may be one of the most common disturbances in otherwise continuous forested habitat in the southern Appalachian Mountains. Despite their obvious presence on the landscape, there is limited data on the ecological effects along a road edge or the size of the "road-effect zone." We sampled salamanders at current and abandoned road sites within the Nantahala National Forest, North Carolina (U...

This paper presents a comparative study of the performance of distance relays for transmission line high voltage (HV) 400 kV in Eastern Algerian transmission networks at Group Sonelgaz compensated by two different series Flexible AC Transmission System (FACTS) i.e. GTO Controlled Series Capacitor (GCSC) and Thyristor Controlled Series Capacitor (TCSC) connected at midpoint of an electrical tran...

raccoon is a native species to north and central america. at present, it is an invasive species in many countries such as japan, germany, russia and iran. raccoon was observed for the first time in gilan province in iran in 1991. this research was employed ecological niche factor analysis (enfa) method to model habitat selection of raccoon in lavandevil wildlife refuge. the results showed that ...
