Walter Dieminger

Walter Dieminger, was a German space scientist and director of Germany's Max Planck Institute for Aeronomy from 1955 to 1975. Dieminger's research was focused on the ionosphere. Dieminger studied physics between 1935 at the Technical University of Munich. After receiving his Ph. D. for work on electromagnetic waves and the ionosphere with Jonathan Zenneck, he worked at the Deutsche Versuchsanstalt für Luftfahrt. With his focus on research of the ionosphere and electromagnetic waves at his new institute, called the Zentralstelle für Funkberatung. Applying a code invented by his cooperator Karl Rawer he was able to make predictions on shortwave communication for the military and the police; the institute at Leobersdorf continued to monitor the ionosphere until the end of World War II. A group of British physicists supervised the dissolution of the institute; the ionospheric physicist William Roy Piggott opposed the dissolution and managed to transfer most of its scientists and equipment to Lindau am Harz in the British sector of Germany.

This research institute became after several name changes, the Max Planck Institute for Ionospheric Research in 1948. Dieminger became the director of the institute in 1951, renamed the Max Planck Institute for Aeronomy in 1958, he continued his research of the upper atmosphere and was able to participate in several international collaborations. For example, he established a station for ionospheric observations in Tsumeb and cooperated with the Finnish EISCAT facility in Sodankylä. Dieminger was one of the most active scientists in the International Union of Radio Science: Vice-President 1963-69, President 1969-72, he continued with his research. He died in 2000 in Northeim. Dieminger was a member of several academic societies including the German Academy of Sciences Leopoldina, Austrian Academy of Sciences, International Academy of Astronautics and the Finnish Academy of Sciences, he was made an honorary citizen of Katlenbug-Lindau in 1975 and received the Federal Cross of Merit in 1975.

Puerto Rico Highway 511

Puerto Rico Highway 511 is tertiary state highway in Ponce, Puerto Rico. The road runs south to north, connecting PR-14 at its southern terminus to PR-143 at its northern terminus, it runs along the Inabón River in the road's southern portions through barrio Real and along the Anón River in its northern portion, once the road enters barrio Anón. The road is 16.4 kilometers long. Puerto Rico Legislature Joint Resolution 795 of 5 July 2010, which sought to order the Oficina de Gerencia y Presupuesto the assignment of $4.2 million to the Puerto Rico Highways and Transportation Authority to make improvements to the road, was not approved. On 30 March 2011, Puerto Rico Senator Larry Seilhamer Rodríguez, presented Senate Joint Resolution 774 to order the Puerto Rico Highway and Transportation Authority to rebuild PR-511 at km. 11.5 where the road had been damaged in 2005 due to heavy rains. In October 2013, the residents of barrio Anon collected money to make the improvements themselves but their efforts were halted after learning they could be the subjects of lawsuits.
