A 45-year-old male patient went to our observation for a white lesion in the left lower gum.At the anamnesis he reported previous diagnosis of oral erosive and genital lichen planus (discovered 2 and 12 years before respectively) and the excision of 2 small oral squamous papillomas 2 year ago.A PCR-real time test using a saliva sample was carried o
Wind energy systems (WESs) based on doubly-fed induction generators (DFIGs) have enormous potential for meeting the future demands related to clean energy.Due to the low inertia and intermittency of power injection, a WES is equipped with a virtual inertial controller (VIC) to support the system during a frequency deviation event.The frequency devi
The Kola region hosts numerous Paleozoic massifs of ultrabasic alkaline rocks and carbonatites with deposits of commercially valuable metals, such as iron, tantalum, niobium, and rare earth elements.These magmatic complexes are characterized by high contents of alkaline elements at generally low contents of SiO2 and/or Al2O3.In this study, we exami
While geobotanists have long used plant occurrence to locate subsurface resources, none have utilised floristic surveys as evidence in models of mineral potential.Here, we combine plant species distributions with terrain metrics to custom congratulations banner produce predictive models showing the probability of bauxite presence.We identified nine
