Ice (Dukaj novel)

Ice (Polish: Lód) is a Janusz A. Zajdel, European Union Prize for Literature and Kościelski awards-winning novel written in 2007 by the Polish science fiction writer Jacek Dukaj, published in Poland by Wydawnictwo Literackie. The novel mixes alternate history with science fiction elements, in particular, with alternative physics and logic.

Ice will be published in English by Atlantic Books in June 2012; and possibly in other languages too.

Universe

The story of the book takes place in an alternate universe where the First World War never occurred and Poland is still under Russian rule. Following the Tunguska event, the Ice, a mysterious form of matter, has covered parts of Siberia in Russia and started expanding outwards, reaching Warsaw. The appearance of Ice results in extreme decrease of temperature, putting the whole continent under constant winter, and is accompanied by Lute, angels of Frost, a strange form of being which seems to be a native inhabitant of Ice. Under the influence of the Ice, iron turns into zimnazo (cold iron), a material with extraordinary physical properties, which results in the creation of a new branch of industry, zimnazo mining and processing, giving birth to large fortunes and new industrial empires. Moreover, the Ice freezes History and Philosophy, preserving the old political regime, affecting human psychology and changing the laws of logic from many-valued logic of "Summer" to two-valued logic of "Winter" with no intermediate steps between True and False.

Ląd, Greater Poland Voivodeship

Ląd [lɔnt] is a village in the administrative district of Gmina Lądek, within Słupca County, Greater Poland Voivodeship, in west-central Poland. It lies approximately 12 kilometres (7 mi) south of Słupca and 71 km (44 mi) east of the regional capital Poznań.

The village has a population of 60.

Cistercian Abbey

The village is the location of a Cistercian monastery, the Ląd Abbey. Founded about 1150 one kilometer south of the village center, it is one of the seven daughter houses of the Altenberg Abbey. Its major buildings date from the 16th and 17th centuries. In 1796 most of its surrounding property was confiscated by the Prussian government, and in 1819 the Cistercian monastery was dissolved.

From 1921 it has been operated and maintained by the Salesians of Don Bosco. The Polish World War II martyr Kazimierz Wojciechowski served there as a tutor in the 1920s.

The abbey is one of Poland's official national Historic Monuments (Pomnik historii), as designated July 1, 2009 and tracked by the National Heritage Board of Poland.

Týr

Týr (/ˈtɪr/;Old Norse: Týr [tyːr]) is a god associated with law and heroic glory in Norse mythology, portrayed as one-handed. Corresponding names in other Germanic languages are Gothic Teiws, Old English Tīw and Old High German Ziu and Cyo, all from Proto-Germanic *Tīwaz. The Latinised name is Tius or Tio.

In the late Icelandic Eddas, Tyr is portrayed, alternately, as the son of Odin (Prose Edda) or of Hymir (Poetic Edda), while the origins of his name and his possible relationship to Tuisto (see Tacitus' Germania) suggest he was once considered the father of the gods and head of the pantheon, since his name is ultimately cognate to that of *Dyeus (cf. Dyaus), the reconstructed chief deity in Indo-European religion. It is assumed that Tîwaz was overtaken in popularity and in authority by both Odin and Thor at some point during the Migration Age, as Odin shares his role as God of war.

Týr is a god of war and will take mead, meat and blood for sacrifice. If a warrior carved the rune Tîwaz on his weapon he would be dedicating it to Týr and strengthen the outcome of a battle to be in his favor. After a warrior has dedicated his weapon to Týr he should not lose it or break it. Tiw was equated with Mars in the interpretatio germanica. Tuesday is in fact "Tīw's Day" (also in Alemannic Zischtig from zîes tag), translating dies Martis.

Ceramic capacitor

A ceramic capacitor is a fixed value capacitor in which ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications. Ceramic capacitors are divided into two application classes:

Ceramic capacitors, especially the multilayer style (MLCC), are the most produced and used capacitors in electronic equipment that incorporate approximately one trillion (10¹²) pieces per year.

Ceramic capacitors of special shapes and styles are used as capacitors for RFI/EMI suppression, as feed-through capacitors and in larger dimensions as power capacitors for transmitters.

History

Since the beginning the study of electricity non conductive materials like glass, porcelain, paper and mica have been used as insulators. These materials some decades later were also well-suited for further use as the dielectric for the first capacitors. Porcelain was the precursor in case of all capacitors now belonging to the family of ceramic capacitors.
