+1. Introduction 2. Cyrillic Letter Rumanian Yn
MAIN.HTM 10/13/2006 06:42 PM +1. INTRODUCTION These are comments to "Additional Cyrillic Characters In Unicode: A Preliminary Proposal". I'm examining each section of that document, as well as adding some extra notes (marked "+" in titles). Below I use standard Russian Cyrillic characters; please be sure that you have appropriate fonts installed. If everything is OK, the following two lines must look similarly (encoding CP-1251): (sample Cyrillic letters) АабВЕеЗКкМНОопРрСсТуХхЧЬ (Latin letters and digits) Aa6BEe3KkMHOonPpCcTyXx4b 2. CYRILLIC LETTER RUMANIAN YN In the late Cyrillic semi-uncial Rumanian/Moldavian editions, the shape of YN was very similar to inverted PSI, see the following sample from the Ноул Тестамент (New Testament) of 1818, Neamt/Нямец, folio 542 v.: file:///Users/everson/Documents/Eudora%20Folder/Attachments%20Folder/Addons/MAIN.HTM Page 1 of 28 MAIN.HTM 10/13/2006 06:42 PM Here you can see YN and PSI in both upper- and lowercase forms. Note that the upper part of YN is not a sharp arrowhead, but something horizontally cut even with kind of serif (in the uppercase form). Thus, the shape of the letter in modern-style fonts (like Times or Arial) may look somewhat similar to Cyrillic "Л"/"л" with the central vertical stem looking like in lowercase "ф" drawn from the middle of upper horizontal line downwards, with regular serif at the bottom (horizontal, not slanted): Compare also with the proposed shape of PSI (Section 36). 3. CYRILLIC LETTER IOTIFIED A file:///Users/everson/Documents/Eudora%20Folder/Attachments%20Folder/Addons/MAIN.HTM Page 2 of 28 MAIN.HTM 10/13/2006 06:42 PM I support the idea that "IA" must be separated from "Я". -
Old Cyrillic in Unicode*
Old Cyrillic in Unicode* Ivan A Derzhanski Institute for Mathematics and Computer Science, Bulgarian Academy of Sciences [email protected] The current version of the Unicode Standard acknowledges the existence of a pre- modern version of the Cyrillic script, but its support thereof is limited to assigning code points to several obsolete letters. Meanwhile mediæval Cyrillic manuscripts and some early printed books feature a plethora of letter shapes, ligatures, diacritic and punctuation marks that want proper representation. (In addition, contemporary editions of mediæval texts employ a variety of annotation signs.) As generally with scripts that predate printing, an obvious problem is the abundance of functional, chronological, regional and decorative variant shapes, the precise details of whose distribution are often unknown. The present contents of the block will need to be interpreted with Old Cyrillic in mind, and decisions to be made as to which remaining characters should be implemented via Unicode’s mechanism of variation selection, as ligatures in the typeface, or as code points in the Private space or the standard Cyrillic block. I discuss the initial stage of this work. The Unicode Standard (Unicode 4.0.1) makes a controversial statement: The historical form of the Cyrillic alphabet is treated as a font style variation of modern Cyrillic because the historical forms are relatively close to the modern appearance, and because some of them are still in modern use in languages other than Russian (for example, U+0406 “I” CYRILLIC CAPITAL LETTER I is used in modern Ukrainian and Byelorussian). Some of the letters in this range were used in modern typefaces in Russian and Bulgarian. -

Introduction. This document requests the addition of a nine Cyrillic characters to the UCS, extending the set of combining characters introduced in the Cyrillic Extended A block (U+2DE0..2DFF). These characters occur in medieval Church Slavonic manuscripts from the 10th/11th to the 17th centuries CE which are at present the object of scholarly investigations and publications in printed and electronic form. They are also used in modern ecclesiastical editions of liturgical and religious books. The set comprises nine superscript letters for which examples from representative primary sources are given. Printed samples of all units proposed for addition are to be found in the new Belgrade table, worked out by a group of slavists in 2007-08 (cf. BS). They also occur in certain Cyrillic fonts composed for scholarly publications, like the one designed by Victor A. Baranov at Izhevsk Technical university. 2. Additional combining characters. Principally, the superscription of characters in medieval Cyrillic manuscripts and printed ecclesiastical editions fulfils two major functions—the classification of abbreviations (in addition to other means, inherited from the Greek mother-tradition: per suspensionem— for common words of liturgical rubrics, and per contractionem—for nomina sacra, cf. -
Preparation and Characterization of Lab6 Ultra Fine Powder by Combustion Synthesis
Preparation and characterization of LaB6 ultra fine powder by combustion synthesis DOU Zhi-he, ZHANG Ting-an, ZHANG Zhi-qi, ZHANG Han-bo, HE Ji-cheng Key Laboratory for Ecological Utilization of Multimetallic Mineral of Ministry of Education, Northeastern University, Shenyang 110004, China Received 25 November 2010; accepted 16 May 2011 Abstract: High-purity, homogeneous and ultra fine LaB6 powders were prepared by combustion synthesis. The effects of reactant ratio and molding pressure on the phase and morphology of the combustion products were studied. The combustion products and leached products were analyzed by XRD, SEM and EDS. The results indicate that the combustion product consists of LaB6, MgO and a little Mg3B2O6. The combustion product becomes denser and harder when the molding pressure increases. The purity of LaB6 is higher than 99.0%. The LaB6 particle size is in range of 1.92–3.00 µm and the lattice constant of LaB6 is a=0.414 8 nm. Key words: combustion synthesis; lanthanum hexaboride; Mg3B2O6 content of free carbon in LaB6 products) and a poorer 1 Introduction sintering property. Although the nano-sized powders of LaB6 could be prepared by chemical vapor deposition Lanthanum hexaboride (LaB6) with divalent (CVD) [9], the yield was lower for a longer production rare-earth cubic hexaborides [1] has high melting point process. Therefore, it is important to develop an efficient (2 715 °C), high hardness, high chemical stability [2] and method to prepare LaB6 powders with high purity and the other special peculiarities [3] such as high and small particle size. Combustion synthesis has attracted constant electrical conductivity, low electronic work much attention to the synthesis of novel materials function, low expansion coefficient and high neutron because of high reaction speed, high temperature, high absorbability [4]. -
Computing PI and Omega Polynomials of an Infinite Family of Fullerenes
MATCH Commun. Math. Comput. Chem. 60 (2008) 905-916 MATCH Communications in Mathematical and in Computer Chemistry ISSN 0340 - 6253 Computing PI and Omega Polynomials of an Infinite Family of Fullerenes A. R. Ashrafi,1 M. Jalali,1 M. Ghorbani1 and M. V. Diudea2 1Institute of Nanoscience and Nanotechnology, University of Kashan, Kashan 87317-51167, I R Iran 2Faculty of Chemistry and Chemical Engineering, Babes-Bolyai University, Arany Janos 11, 400028 Cluj, Romania (Received September 16, 2007 ) Counting of non-equidistant edges in a graph can be achieved in the formalism of PI-type polynomials. At least three ways of evaluating the equidistance of edges are discussed and the corresponding conditions established. Two versions of polynomials counting non-equidistant edges (PI-type polynomials) and two polynomials counting equidistant edges (Theta and Omega polynomials) are discussed and analytical formulas for an infinite series of tubulenes/fullerenes, derived from the dodecahedron C20, are developed. 1. Introduction Fullerenes are molecules in the form of cage-like polyhedra, consisting solely of carbon atoms. Fullerenes Cn can be drawn for n = 20 and for all even n ≥ 24. They have n carbon atoms, 3n/2 bonds, 12 pentagonal and n/2-10 hexagonal faces. The 1,2 most important member of the family of fullerenes is C60. Let G = (V,E) be a connected bipartite graph with the vertex set V = V(G) and the edge set E = E(G), without loops and multiple edges. In 1988, Hosoya3 introduced what he termed the Wiener (and latter called Hosoya) polynomial of a graph as HGx(,)=⋅∑ mGk (,) xk , where m(G,k) is the number of pairs of vertices in G 1<<kl that are distance k apart, and l is the maximum value of k or the diameter of G. -

Details About Three Fatty Acid Oxidation Pathways Occurring in Man
Supplement information Details about three fatty acid oxidation pathways occurring in man Alpha oxidation Definition: Oxidation of the alpha carbon of the fatty acid, chain shortened by 1 carbon atom. Localization: Peroxisomes1 Substrates: Phytanic acid, 3-methyl fatty acids and their alcohol and aldehyde derivatives, metabolites of farnesol, geranylgeraniol, and dolichols2, 3. Steps in the pathway: Activation requires ATP and CoA. Hydroxylation requires iron, ascorbate and alpha-keto-glutarate as cofactors and secondary substrates. Lysis requires thymine pyrophosphate and magnesium ions. Dehydrogenation requires NADP. End products are transported into mitochondria for further oxidation. Enzymes and genes involved: Very long-chain acyl-CoA synthetase (E.C. 6.2.1.-) (SLC27A2, GeneID: 11001)4, phytanoyl-CoA dioxygenase (E.C. 1.14.11.18, PHYH, GeneID: 5264), 2-hydrosyphytanoyl-coA lyase (E.C. 4.1.-.-, HACL1, GeneID: 26061), and aldehyde dehydrogenase (E.C. 1.2.1.3, ALDH3A2, GeneID: 224). Disorders associated: Zellweger syndrome including RCDP type 1, where PTS2 receptor is defective and PHYH is unable to enter peroxisomes, and Refsum’s disease. Special features/ purpose: At the sub cellular level, the activation step can occur in the mitochondrion, endoplasmic reticulum, and peroxisome. Formic acid is the main byproduct of this pathway as opposed to carbon dioxide. Phytanic acid usually undergoes alpha oxidation; however, under conditions of enzyme deficiency, it undergoes omega oxidation and 3- methyladipic acid is produced as the end product5. Omega oxidation Definition: Oxidation of omega carbon of the fatty acid for generation of mono- and di- carboxylic acids. No chain shortening occurs. Localization: Fatty acid shuttles between cytosol and microsomes before entering the peroxisomes6. -

Um var að ræða fiskflök, hrogn, rækju, humar og ýmsar unnar afurðir. Mælingar voru gerðar á fitusýrum, joði og þremur vítamínum í völdum sýnum. Nokkrar afurðir voru efnagreindar bæði hráar og matreiddar. Markmið verkefnisins var að bæta úr skorti á gögnum um íslenskar sjávarafurðir og gera þær aðgengilegar fyrir neytendur, framleiðendur og söluaðila íslenskra sjávarafurða. Upplýsingarnar eru aðgengilegar í íslenska gagnagrunninum um efnainnihald matvæla á vefsíðu Matís. Selen var almennt hátt í þeim sjávarafurðum sem voru rannsakaðar (33‐ 50 µg/100g) og ljóst er að sjávarafurðir geta gegnt lykilhlutverki við að fullnægja selenþörf fólks. Fitusýrusamsetning var breytileg eftir tegundum sjávarafurða og komu fram sérkenni sem hægt er að nýta sem vísbendingar um uppruna fitunnar. Meginhluti fjölómettaðra fitusýra í sjávarafurðum var langar ómega‐3 fitusýrur.
