The sailing efficiency of an underwater glider, an important type of marine environment detection and data collection equipment, directly affects its range and duration.The zero-angle-of-attack gliding can be achieved by adjusting the wing installation angle to minimize the drag and improve the sailing efficiency, and thus further improving perform
In this study, the efforts have been made to obtain relatively high dielectric constant polymer-ceramic composite by incorporating the giant dielectric constant material, calcium copper titanate (CCTO) in a PVC polymer matrix.We have prepared composites of CaCu3Ti4O12 (CCTO) ceramic and Poly Vinyl Chloride (PVC) polymer in various ratios (by volume
Climate change creates challenges for wild species, but plants have survived and adapted to similar changes in their evolutionary past.Most plants 203 were originally outcrossing, one theoretical genetic reason being that self-fertilization does not create novel recombinants that allow adaptation.Thus selfing seems an evolutionary “dead end&#
Cervical spondylosis is a chronic degenerative disease which is prevalent in middle and aging population.Its cause is multifactorial attributing to stress, anxiety, trauma, sports, occupational factors or use of handheld devices.It is easily missed and neglected as it has an insidious onset, early subtle features, ORG SEA SALTED PISTACHIOS and rese
Agricultural areas can benefit from the reduction of rodents by raptors, yet many croplands and pastures do not provide adequate perching structures needed by raptors to hunt effectively.Many artificial raptor perches have been constructed as a solution to this deficiency, Table Lamp however, monitoring the benefits of these perches has proved chal
