ISS033-E-019822 (9 Nov. 2012) --- An eruption plume from the Karymsky volcano on the Kamchatka Peninsula in the Russian Federation is visible in this image photographed by an Expedition 33 crew member on the International Space Station. The Karymsky stratovolcano stands 1,536 meters above sea level, with most eruptions and occasional lava flows originating from the summit. Karymsky is the most active of Kamchatka’s eastern volcanoes, with almost constant (on a geologic time scale) volcanism occurring since at least the late 18th century when the historical record for the region begins. In light of the high levels of volcanic activity on the Kamchatka Peninsula, the Kamchatka Volcanic Eruption Response Team (KVERT) monitors the activity levels of several volcanoes and issues updates including aviation alerts and webcams. KVERT reported moderate seismic activity at Karymsky during 2-9 Nov. 2012; such activity can indicate movement of magma beneath or within a volcanic structure and can indicate that an eruption is imminent. The Tokyo Volcanic Ash Advisory Center (VAAC) subsequently reported an explosive eruption at Karymsky on Nov. 9, 2012 at 22:15 GMT. This photograph of the resulting ash plume was taken approximately one hour and 35 minutes after the eruption began. The plume extends from the summit of Karymsky (bottom center) to the southeast, with brown ash deposits darkening the snow cover below the plume. The Akademia Nauk caldera – now filled with water to form the present-day Karymsky Lake - is located to the south of Karymsky volcano. Calderas are formed by explosive eruption and emptying of a volcano’s magma chamber – leading to collapse of the structure to form a large crater-like depression. Akademia Nauk last erupted in 1996.

Under a complex geological region influenced by the subduction of the Pacific plate, Kamchatka Peninsula is one of the most active volcanic arcs in the Pacific Rim. Due to logistical difficulty in instrumentation, shallow magma plumbing systems beneath some of the Kamchatkan volcanoes are poorly understood. InSAR offers a safe and quick method for monitoring volcanic deformation with a high spatial resolution. In this study, a group of satellite radar interferograms that span the time interval from 2000 to 2010 shows eruptive and non-eruptive deformation at Karymsky Volcanic Center (KVC), Kamchatka, Russia. All the interferograms provide details of the activity around the KVC during 2000-2010, as follows: (1) from 2000 to 2004, the Karymsky-AN (Akademia Nauk) area deflated and the MS (Maly Semyachik) area inflated, (2) from 2004 to 2006, the Karymsky-AN area deflated with ongoing eruption, while the MS area subsided without eruption, (3) from 2006 to 2008, as with 2000-2004, the Karymsky-AN area deflated and the MS area inflated, (4) from 2008 to 2010, the Karymsky-AN area inflated up to 3 cm, and the MS area subsided. Point source models suggest that two magma reservoirs provide a good fit to the observed deformation. One source is located beneath the area between Karymsky and AN at a depth of approximately 7.0 km, and the other one is situated beneath MS at a depth of around 5.8 km. Synchronous deformation patterns suggest that two magma systems are fed from the same deep magma source and connected by a fracture zone. The InSAR results are consistent with GPS ground deformation measurements, seismic data, and petrological constraints.

origins in the Chair of Anatomy and Medicine at Danzig Academic Gymnasium (GA; Sive Illustre), an establishment which lasted for 239 years, from 1584 to 1812. The history of surgery in Danzig has its roots in the centuries-old tradition of the medical practice of surgeons who were associated in the Surgeons Guild, teaching, as well medical and scientific research. The Surgeons Guild existed in Danzig from 1454 to 1820. Over the centuries manual intervention was also in the hands of academically uneducated persons such as bath house attendants, barbers, and wandering surgeons. Until the end of 1946 there was no separate urology department in Danzig. Urological surgery was in the hands of surgeons. Interventions and operations on genitourinary organs were carried out, more or less, in all surgical departments. The end of World War II created a new political situation in Europe. Danzig (now Gdafisk) and Pomerania became part of Poland. In 1945, on the basis of the former MAD, the Polish Government established the Polish Academy of Physicians, later renamed the Medical Academy in Gdafisk (Gdafiska Akademia Medyczna - GAM). In 2009, GAM was again renamed, as the Medical University of Gdafisk (Gdaiski Uniwersytet Medyczny). The political changes after World War II accelerated the process of the separation of urology from surgery. In May 1947, a 30-bed Urological Ward was opened in Gdanisk, in Debinki Street, forming part of the First Surgical Clinic of the Academy of Physicians (headed by Prof. Kornel Michejda, 1887-1960, later by Prof. Stanislaw Nowicki, 1893-1972, and lastly by Prof. Zdzislaw Kieturakis, 1904-1971). The first head doctor of the new urological ward was Dr. Tadeusz L$renz (1906-1986), a urologist from Lvov (Lemberg). After the departure of Professor Lorenz to Wrodclaw (Breslau) in 1958, Dr. Jan Renkielski was acting as Head of the Urological Ward until 1971. In 1971 the ward was transformed to the separate Department of Urology. Docent ("lecturer"), and later
