A multi-hop free space optical link Dolls based on all-optical relays is presented.All-optical relays are either composed of simple optical amplifiers or optical regenerators.It has been shown that after a certain number of hops, the amplifier based relay cannot extend the range of the free space optical link.Therefore, we have investigated the use
Based on immunomodulatory, osteogenic, and pro-angiogenic properties of adipose-derived stem cells (ASCs), this study aims to assess the safety and efficacy of ASC-derived cell therapies for clinical indications.Two autologous ASC-derived products were proposed to 17 patients who had not experienced any success with conventional therapies: (1) a sc
Traumatic acute subdural hematoma Dolls (ASDH) is generally addressed by craniotomy under general anesthesia.We report a patient whose traumatic ASDH was treated under local anesthesia by one-burr-hole endoscopic surgery.This 87-year-old woman had undergone coil embolization for a ruptured right middle-cerebral artery aneurysm and placement of a ve
The outflow of freshwater from underwater channels in the Kongsbreen tidal glacier in Kongsfjorden, Svalbard, 79oN, was measured as 138.8 m3 s-1 at Debresk the peak of the melting season.Experiments on local marine plankton mortality show that when exposed to salinities below 9 PSU, all copepods die within 15 minutes.We estimate that during 100 day
