Quality of Recovery Evaluation of the Protection Schemes for Fiber-Wireless Access Networks
Authors: Fu Minglei , Chai Zhicheng , Le Zichun 
Published: March 2015

AbstractWith the rapid development of fiber-wireless (FiWi) access network, the protection schemes have got more and more attention due to the risk of huge data loss when failures occur. However, there are few studies on the performance evaluation of the FiWi protection schemes by the unified evaluation criterion. In this paper, quality of recovery (QoR) method was adopted to evaluate the performance of three typical protection schemes (MPMC scheme, OBOF scheme and RPMF scheme) against the segment-level failure in FiWi access network. The QoR models of the three schemes were derived in terms of availability, quality of backup path, recovery time and redundancy. To compare the performance of the three protection schemes comprehensively, five different classes of network services such as emergency service, prioritized elastic service, conversational service, etc. were utilized by means of assigning different QoR weights. Simulation results showed that, for the most service cases, RPMF scheme was proved to be the best solution to enhance the survivability when planning the FiWi access network.

Abstract
This work concentrates on stagnation point flow
of a nanofluid over an impermeable stretching cylinder
with mass transfer and slip effects. Carbon nanotubes
(CNTs) and water are used as a nanofluid in the present investigation.
Two types of CNTs are used as nanoparticles
(i) Single-wall carbon nanotubes (SWCNTs) and (ii) multiwall
carbon nanotubes (MWCNTs). Appropriate transformations
are used to achieve a system of ordinary differential
equations. Convergent series solutions are obtained.
Behavior of various parameters on the velocity, temperature
and concentration profiles are discussed graphically.
Numerical values of skin friction coefficient, Nusselt number
and Sherwood number are computed and analyzed.
Fatigue Life Analysis of Turbine Disks Based on Load Spectra of Aero-engines
Authors: Li Yan-Feng , Lv Zhiqiang , Cai Wei , Zhu Shun-Peng , Huang Hong-Zhong 
Published: March 2015

AbstractLoad spectra of aero-engines reflect the process of operating aircrafts as well as the changes of parameters of aircrafts. According to flight hours and speed cycle numbers of the aero-engines, the relationship between load spectra and the fatigue life of main components of the aero-engines is obtained. Based on distribution function and a generalized stress–strength interference model, the cumulative fatigue damage of aero-engines is then calculated. After applying the analysis of load spectra and the cumulative fatigue damage theory, the fatigue life of the first-stage turbine disks of the aero-engines is evaluated by using the
Bipodal benzoylthiocarbamic acid esters: crystal and molecular structures of R = Et (a polymorph), and of a binuclear Cu(I) complex, R = iPr

Abstract
The crystal and molecular structure of a second polymorph (P21/n) of [1,4-ROC(=S)N(H)C(=O)C6H4C(=O)N(H)C(=S)OR], R = Et, is shown to have inversion symmetry and to have a more twisted conformation than the previously reported P43212 form which has 2-fold symmetry. Despite utilising equivalent atoms in forming intermolecular interactions, very distinct crystal packing patterns are observed. Crystal characteristics and theory (DFT) are consistent with the P43212 form being more stable, a conclusion correlated with the observation that this form is the overwhelming majority of the sample (PXRD). An analysis of a binuclear copper(I) complex containing the R = iPr analogue, reveals the neutral ligand to bind via the thione-S atom resulting in a distorted ClP2S tetrahedral geometry.
Protonenrelaxation und Hydratation in wäßrigen Lösungen des Manganions
Authors: Pfeifer H. 
Published: March 2015

Die Protonenrelaxationszeiten in wäßrigen Lösungen paramagnetischer Ionen wurden bislang im Gegensatz zu denen reiner Flüssigkeiten unter Vernachlässigung des sogenannten Translationsanteils behandelt. Dieser Translationsanteil erfaßt die Wechselwirkungen mit allen den magnetischen Partnern, die nicht zum gleichen Molekül oder Komplex gehören.
In der vorliegenden Arbeit wird der Einfluß des Translationsanteils in wäßrigen Lösungen von Manganionen, die aus verschiedenen Gründen vorteilhaft erscheinen, experimentell und theoretisch untersucht. Die Resultate lassen sich deuten, wenn man eine Bewegungsbehinderung der Wassermoleküle außerhalb der ersten Schicht der Hydrathülle (Fernhydratation) durch einen effektiven Diffusionskoeffizienten in Rechnung setzt, der etwa sechsmal kleiner ist als der von reinem Wasser. Der relative Beitrag des Translationsanteils an der resultierenden Relaxationszeit ergibt sich dann etwa zu 10 — 20%. Die Aussagen bezüglich der Nahhydratation stehen im wesentlichen in Übereinstimmung mit früheren Untersuchungen.
Die Zentrifugalkorrektur im Rotationsspektrum eines Moleküls mit interner Rotation, untersucht am (CH3)2S
Authors: Rudolph Heinz Dieter 
Published: March 2015

55 rotational transitions of the prevailing isotopic species of (CH3)2S recorded between 12 and 63 kmc/s and all split into triplets or quartets by the interaction of over-all and two-top internal rotation (torsional ground state) have been fitted with high precision to a KIVELSON–WILSON 1 centrifugal distortion formula. The transition frequencies to be used are those of “centroids” of the multiplets—where single absorption lines would be found without internal rotation—rather than those of the individual multiplet lines. For symmetrical triplets and certain quartets the centroid frequency is easily obtained as a weighted average of the frequencies of the “pseudo-rigid” multiplet lines. This treatment considers the perturbations due to centrifugal distortion and internal rotation as independent. The distortion formula reproduces the 55 centroids with a rms error of only 15 kc/s. The mean centrifugal distortion correction is 15 mc/s (the highest found 54 mc/s). The mean width of the multiplets is 1.5 mc/s. The values of the rotational constants and the six centrifugal coefficients contained in the distortion formula as fitting parameters are given.
After the completion of this report two more transitions involving J &gt; 12 were measured. Although their centrifugal corrections are large, 87 and 126 mc/s, the centroids of the two multiplets were found within 15 resp. 30 kc/s of the frequencies predicted by a distortion formula 1 using the previously determined parameters.

Zur Frage der Beteiligung intrazellulärer Hemmfaktoren bei der Proteinsynthese von Acetabularia
Authors: Clauss H. 
Published: March 2015

Nach STICH und KITIYAKARA soll durch Unterteilung kernloser Zellen von Acetabularia crenulata die Proteinsynthese gegenüber unbehandelten ganzen Zellen stimuliert werden. Auf Grund dieser Befunde wurde auf einen die Proteinsynthese kontrollierenden „inhibitory mechanism“ geschlossen.
Bei Wiederholungen dieser Versuche konnten die Ergebnisse dieser Autoren nicht bestätigt werden. Die Zunahme der Zellproteine ist weitgehend unabhängig davon, ob die kernlose Zelle als ganze, halbiert, geviertelt oder geachtelt untersucht wird. Diese Befunde sprechen dafür, daß bei der Entfernung des Zellkernes das weitere Schicksal der Zelle, auch hinsichtlich der Proteinsynthese, festgelegt ist.

Abstract
The cycloaddition of nitriles and of dimethylacetylenedicarboxylate to the azide ligand of polymeric Schiff Base cobalt(III) and phosphine palladium(II) complexes gives the corresponding tetrazolate and triazolate complexes from which the heterocycles could be cleaved by hydrogen chloride. Usually the yields are low; if the heterocycle is soluble in ether or sublimable, yields up to 30% have been obtained. Using this method the hitherto unknown 5-trichlormethyltetrazole could be prepared which was characterized by an X-ray structural analysis. Similarly, the cyclo-addition of azido(tetraphenylporphinato)cobalt(III) with nitriles, cyclohexylisocyanide and MeO2CC≡CCO2 Me affords the corresponding complexes with heterocyclic ligands. The prepa-ration of tetraphenylporphyrinato(tricyanmethanido)cobalt(III), (TPP)CoN=CC(CN)2 , is reported.

Abstract
Reduction of [(cyclo-C7H8)RuCl2]2 in the presence of a diazadiene RN=CH−CH=NR (DAD; R = i-C3H7) gives red, airsensitive, sublimable (η6-C7H8)Ru(DAD) (5). A rigid structure on the basis of the 1H NMR spectrum is excluded. On the other hand pentacoordinate complexes [η4-nor-C7H8)Ru(DAD)P(C6H5)3] (8) or [(η4-nor-C7H8)Ru(DAD)CO] (9) have rigid, Cs-symmetric, square-pyramidal structures. They are obtained by chemical or irreversible electro-chemical reduction of [(η4-nor-C7H8)Ru(DAD)Cl2] to [η4-nor-C7H8)Ru(DAD)(solv)] (7) (solv = tetrahydrofuran or acetonitrile) and addition of phosphine or carbon monoxide. 7, in non-coor-dinating solvents, is a stereospecific catalyst for the 1-alkene → trans-2,... -alkene isomerization.

trans-1,2-Dichloro-1,2-bis(trichlorosilyl)ethene (1) was prepared from Cl3CSiCl3 and copper powder, and its structure determined by single crystal X-ray diffraction (monoclinic, space group P21/n, a = 7.297(1), b = 10.964(1), c = 7.988(1) Å, β = 108.06(1)°; R = 0.037, Rw = 0.066). Cl3SiC=CSiCl3 , 2, forms a cobalt cage cluster on reaction with Co2(CO)8 formulated as (CO)6Co2C2(SiCl3)2 . Hydrosilylation with HSiCl3 gives tris(trichlorosilyl)ethene. -Bis(trimethylsilyl)ethine adds HSiCl3 to form 1-trichlorosilyl-1,2-bis(trimethylsilyl)ethene, which can be converted into the hydride with i-BU2AlH. All compounds are model systems for CVD production of amorphous silicon a-Si:C.
Low Temperature Raman Spectra of Dichlorosulfane (SCl2), Tetrachlorosulfurane (SCl4), Dichlorodisulfane (S2Cl2) and Dichlorodiselane (Se2Cl2)
Authors: Steudel Ralf , Jensen Detlef , Plinke Bettina 
Published: March 2015

Abstract
The Raman spectrum of commercial "sulfur dichloride" shows strong lines due to SCl2 and S2Cl2 and weak Cl2 lines at 25 °C, but strong SCl2 and SCl4 signals at -100 °C (the latter are superimposed on the S2Cl2 lines). Thus, the intense Raman effect of SCl4 can be used to detect small amounts of chlorine in SCl2 . Mixtures of SCl2 and Cl2 (1:15) yield the Raman spectrum of SCl4 at -140 °C, while at 25 °C not trace of this compound can be detected. The spectra of SCl4 and α-SeCl4 are quite different, indicating different molecular and/or crystal structures, although ECl3 + ions (E = S, Se) are present in both cases. While Se2Cl2 dimerizes reversibly below -50 °C, S2Cl2 neither dimerizes nor isomerizes on cooling. The S2Cl2 dimer is characterized by a Raman line at 215 cm-1 the intensity of which was used to calculate an enthalpy of dimerization as of -17 kJ/mol.

Published: March 2015

Abstract
The reaction of tris(ethene)nickel(0) with stoichiometric amounts of bis(dimethylphos-phino)methane (dmpm) in ether at low temperature affords the yellow crystalline, dinuclear complexes (dmpm)Ni2(C2H4)4 (1) and (dmpm)2Ni2(C2H4)2 (2). 2 reacts with ethyne to yield (dmpm)2Ni2(C2H2)2 (3). When 2 is treated with CO at -40 °C the primary product is (dmpm)2Ni2(CO)2(μ-CO) (4). At 20 °C 4 is converted by additional CO into (dmpm)2Ni2(CO)4 (5), which has already been characterized as the reaction product of Ni(CO) 4 with dmpm. In compounds 1-5 the bidentate dmpm acts as a bridging and not as a chelating ligand. The structures of complexes 1-4 were assigned on the basis of their 13C and 31P NMR spectra.
