The Scientific Correspondence of H.A. Lorentz
Author: A.J. KoxPublisher: Springer
ISBN: 3319903292
Category : Mathematics
Languages : en
Pages : 886
Book Description
This is the second and final volume of Dutch physicist Hendrik Antoon Lorentz's scientific correspondence with Dutch colleagues, including Pieter Zeeman and Paul Ehrenfest. These 294 letters cover multiple subjects, ranging from pure mathematics to magneto-optics and wave mechanics. They reveal much about their author, including Lorentz's surprisingly active involvement in experimental matters in the first decades of his career. Letters are also devoted to general relativity, Lorentz's 1908 lecture on radiation theory, and his receipt of the Nobel Prize along with Zeeman in 1902. The letters are presented in their original language; Dutch originals are accompanied by English translations. A concise biography of Lorentz is also included.

Book Description
In The Netherlands, Belgium and other European countries, manganese is removed by conventional groundwater treatment with aeration and rapid (sand) filtration. Such a treatment process is easy to operate, cost effective and sustainable, because it does not make use of strong oxidants such as O3, Cl2, ClO2 and KMnO4 with the associated risk of by-product formation and over or under dosing. However, application of aeration-filtration is also facing drawbacks, especially the long ripening time of filter media. Due to the long ripening time, water companies have to waste large volumes of treated water, making this process less sustainable. Also, costs associated with filter media ripening (man power, electricity, operational and analysis costs) are high. Therefore decreasing the filter ripening time, regarding manganese removal is a big issue. Although already extended research has been carried out into manganese removal, the controlling mechanisms, especially of the start up face of filter media ripening, are not fully understood yet. The emphasis of this thesis is to provide a better understanding of the mechanisms involved in the ripening of virgin filter media, regarding manganese removal and how to shorten or completely eliminate the long ripening period of filters with virgin material. This thesis therefore highlights the role of the formation of a manganese oxide coating on virgin filter media. Characterization and identification revealed that the responsible manganese oxide for an effective manganese removal was Birnessite. It was found that Birnessite, formed at the beginning of the ripening process was of a biological origin. Based on the knowledge that manganese removal in conventional groundwater treatment is initiated biologically, long ripening times may be reduced by creating conditions favouring the growth of manganese oxidizing bacteria, e.g., by limiting the back wash frequency and / or intensity. Additionally, this thesis also shows that the use of freshly prepared manganese oxide, containing Birnessite, can completely eliminate filter media ripening time.

Book Description
A New York Times bestseller The unforgettable story of two unsung heroes of World War II: sisters Janny and Lien Brilleslijper who joined the Dutch Resistance, helped save dozen of lives, were captured by the Nazis, and ultimately survived the Holocaust. Eight months after Germany’s invasion of Poland, the Nazis roll into The Netherlands, expanding their reign of brutality to the Dutch. But by the Winter of 1943, resistance is growing. Among those fighting their brutal Nazi occupiers are two Jewish sisters, Janny and Lien Brilleslijper from Amsterdam. Risking arrest and death, the sisters help save others, sheltering them in a clandestine safehouse in the woods, they called “The High Nest.” This secret refuge would become one of the most important Jewish safehouses in the country, serving as a hiding place and underground center for resistance partisans as well as artists condemned by Hitler. From The High Nest, an underground web of artists arises, giving hope and light to those living in terror in Holland as they begin to restore the dazzling pre-war life of Amsterdam and The Hague. When the house and its occupants are eventually betrayed, the most terrifying time of the sisters' lives begins. As Allied troops close in, the Brilleslijper family are rushed onto the last train to Auschwitz, along with Anne Frank and her family. The journey will bring Janny and Lien close to Anne and her older sister Margot. The days ahead will test the sisters beyond human imagination as they are stripped of everything but their courage, their resilience, and their love for each other. Based on meticulous research and unprecedented access to the Brilleslijpers’ personal archives of memoirs and photos, Sisters of Auschwitz is a long-overdue homage to two young women’s heroism and moral bravery—and a reminder of the power each of us has to change the world.
