Nutrient availability in ecosystems has increased dramatically over the last century.Excess reactive nitrogen deposition is known to negatively impact plant communities, e.g.by changing species composition, biomass and vegetation structure.In contrast, little is known on how such impacts propagate to higher trophic levels.To evaluate how nitrogen d
More than four hundred scholars and guests from around the world attended the "Second International Islamic Conference on Prevention of Drugs and Alcohol" held at the International Islamic University, Islamabad, Pakistan Shawwal 26-28 1409/June 1-3, 1989.The conference, sponsored by Rabita al-Alam al-Islami, Makkah alMukarramah Seat Cushions (World
Cyanobacteria are oxygenic photoautotrophs, exhibiting a cosmopolitan distribution in almost all possible environments and are significantly responsible for half of the global net primary productivity.They are well adapted to the diverse environments including harsh conditions Dishwasher ComfortLift End Stopper by evolving a range of fascinating re
Carbon nanotubes are a new class of microtubule-stabilizing agents since they interact with protein microtubules in living cells, interfering with cell division and inducing apoptosis.In the present work, a modified beam model is Ornaments developed to investigate the effect of carbon nanotubes on the buckling of microtubule bundles in living cell.
Obstacle distance measurement is one of the key technologies for autonomous navigation of high-voltage transmission line inspection Garters robots.To address the robustness of obstacle distance measurement under varying illumination conditions, this article develops a research method that fuses image enhancement with robot monocular vision so that
