Carbidization and size effects of unsupported nanosized iron in the low temperature Fischer-Tropsch process
No full textIncludes abstract.Includes bibliographical references.In the process of developing the most efficient production of fuels from coal or natural gas, there have been major advances in the development of the catalysts used. Previous work at the Centre for Catalysis Research, at the University of Cape Town, has shown great potential and provided a much deeper under- standing of the workings of the Fischer-Tropsch catalyst. The research has found that the catalyst crystallite size plays a crucial part in the product selectivity and requires strict control in order to obtain a certain desired product spectrum. The aim of this project is to provide insight on the behavior of various iron oxide crystallite sizes when placed in a CO concentrated environment during catalyst pretreatment. It will also clarify whether the sizes of the nano-crystallites will increase or decrease when the different phases form and which size carbides faster
A smoothing Newton method based on the generalized Fischer-Burmeister function for MCPs
No full text[[abstract]]We present a smooth approximation for the generalized Fischer-Burmeister function where the 2-norm in the FB function is relaxed to a general p-norm (p > 1), and
establish some favorable properties for it, for example, the Jacobian consistency. With the smoothing function, we transform the mixed complementarity problem (MCP) into
solving a sequence of smooth system of equations.

Prayer Kaddish
No full textKadiš je kratka liturgijska molitva sa eshatološkim fokusom koja se više puta izgovara tokom verske službe (uglavnom na aramejskom) kojom se veliča i slavi Bog. Takođe je i molitva ožalošćenih tokom prve godine žalosti. Kadiš je za sve Jevreje, i pobožne i slobodumne, uzvišen i svet i možda najpopularnija molitva u celokupnoj jevrejskoj liturgiji. Dr Fischer smatra da su njen postanak, razvoj, sadržaj, značaj, jezik i odnos ka spasenju duše malo poznati i da samo moć navike ovoj molitvi daje prividnu snagu. Zbog toga u članku “Molitva Kadiš” želi da protumači sadržaj ove divne molitve i da širu javnost upozna sa njenom istorijom. Govoreći o nastanku ove molitve autor nas upoznaje sa verovatnim izvorima koji se odnose na citate iz Talmuda i Mišne kao i na jednu staru potresnu bajku iz vremena Rab Akibe. Kadiš je prvobitno napisan na hebrejskom jeziku pa se tako citira i pojavljuje u Talmudu. Kasnije je u Vavilonu hebrejski tekst preveden na aramejski ali su odlomci starog hebrejskog teksta očevidno zadržani u delu molitve, koji se i danas govori subotom i praznicima pri iznošenju Tore. Dr Fischer smatra da je neobično da se ova najpoznatija i najčešće izgovarana molitva slabo ili nikako može razumeti te stoga analizira svaki stih posebno dajući nam potrebna objašnjenja i tumačenja. Na kraju rada govori o promenama koje se su događale tokom vremena i poredi prvobitni i savremeni sadržaj Kadiša.Kaddish is a short liturgical prayer with an eschatological focus that is pronounced several times during a religious service (mostly in Aramaic) which praises and glorifies God. There is also the prayer of the grieving during the first year of mourning. For all Jews, both religious and free-spirited, Kaddish is sublime and holy, and perhaps the most popular prayer in the entire Jewish liturgy. Dr. Fischer believes that its origin, development, content, significance, language, and attitude towards the salvation of the soul are slightly known and that only the power of habit gives this prayer illusory strength. That is why in the article "Prayer Kaddish" he wants to interpret the content of this wonderful prayer and to acquaint the general public with its history. Speaking about the origin of this prayer, the author introduces us to probable sources that refer to quotations from the Talmud and the Mishnah, as well as to an old shocking fairy tale from the time of Rab Akiba. Kaddish was originally written in Hebrew, so it is quoted and appears in the Talmud. Later, in Babylon, the Hebrew text was translated into Aramaic, but excerpts from the old Hebrew text were apparently retained in the part of the prayer, which is still spoken today on Saturdays and holidays during the presentation of the Torah. Dr. Fischer finds it unusual that this most famous and most often pronounced prayer can be poorly or not at all understood and therefore analyzes each verse separately giving us the necessary explanations and interpretations. At the end of the paper, he talks about the changes that have taken place over time and compare the original and modern content of Kaddish.Dr Leopold Fischer (1886-1941) bio je rabin u Daruvaru a potom nadrabin u Vršcu. Uređivao je "Jevrejski almanah" godišnjak Saveza rabina Kraljevine SHS, koji je izlazio od 1925 do 1930. Bio je član Glavnoga odbora Saveza jevrejskih opština Jugoslavije i član Upravnoga odbora biblioteke i muzeja grada Vršca. Autor je knjiga i tekstova koji i danas predstavljaju važan izvor u talmudskim studijama. Bio je osoba izuzetnog obrazovanja, govorio je 9 jezika, imao dva doktorata, dopisivao se s brojnim poznatim i uglednim ličnostima (Šalom Alejhem, Šalom Aš, Rabindranat Tagore). Nakon sloma Kraljevine Jugoslavije uhvaćen je i sa ostalim beogradskim Jevrejima deportovan u logor Topovske Šupe u Beogradu, gdje je stradao.Dr. Leopold Fischer (1886-1941) was a rabbi in Daruvar and senior rabbi in Vršac. He was edited "Jewish Almanac" - the yearbook of the Association of Rabbis of the Kingdom of Serbs, Croats and Slovenes, which was published from 1925 to 1930. He was a member of the Main Board of the Federation of Jewish Communities of Yugoslavia and a member of the Board of the Library and Museum of Vršac. He is the author of books and texts that still represent an important source in Talmudic studies. He was a person of exceptional education, he spoke nine languages, he had two doctorates, and he corresponded with many famous and respectable people (Shalom Aleichem, Shalom Ash, Rabindranath Tagore). After the collapse of the Kingdom of Yugoslavia, he was captured and deported with other Belgrade Jews to the Topovske Šupe camp in Belgrade, where he died
Principal Vectors for Spatial Dynamical Analysis by Fischer
No full textOtto Fischer was during the late 19th and early 20th century the founder of 3-D human gait analysis. From motion recordings he calculated by hand the inverse dynamics of humans in motion, for which he discovered and used the principal vectors of a system of moving bodies. With the principal vectors the equations of motion and the kinetic energy can be written in a specific simple form with full geometric meaning and with reduced mass models with which system dynamics can be investigated in a simple way at link level. Fischer applied his theory mainly in its planar form. He also presented the theory of the spatial form by example of a serial two-link chain, however the explanations in the original texts in German are challenging to understand. This paper presents Fischer’s spatial form in a modern and understandable way.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Mechatronic Systems Desig
Collection des Flambeaux, Vol. 10
No full textI had long sought a copy of Fischer's outstanding work and was lucky to find it at an unusual price. As Bodemann's listing indicates, Fischer handles some fifty-five fables from across the twelve books. There is a larger frontispiece and then there are eighty-six beginning and ending illustrations, half a page at their largest. They are extremely stylized. Fine linear etchings, with figures often created without any interruption in the line, but the line does not give the figure's circumference but rather suggests characteristic body elements and binds these to each other. I believe that the lead set of illustrations, with texts, is on Velin du Marais, with a separate set without text on Chine. Compare with the set being offered now for $940. My prizes go to these outstanding illustrations: CW, DS, FK, DW, FC, FM, FS, GA, LM, The Old Cat and the Young Mouse, and The Stag in the Pool. I scanned a copy of each of those. They are simply lovely!Language note: French#34 of 325 numberedSigned by Fischer and GoninJean de La Fontain
