Reliable analysis for the nonlinear fractional calculus model of the semilunar heart valve vibrations
Authors: Yıldırım Ahmet , Gülkanat Yaǧmur 
Published: June 2010

AbstractThe aim of this paper is to solve the equation of motion of semilunar heart valve vibrations using the homotopy perturbation method. The vibrations of the closed semilunar valves were modeled with fractional derivatives. The fractional derivatives are described in the Caputo sense. The methods give an analytic solution in the form of a convergent series with easily computable components, requiring no linearization or small perturbation. Analytical solution is obtained for the equation of motion in terms of Mittag–Leffler function with the help of Laplace transformation. These solutions can be interesting for a better fit of experimental data. Copyright © 2010 John Wiley & Sons, Ltd.
Synthesis and improved electrochemical performance of LiCo1‐xSnxO2 (x= 0 to 0.1) powders
Authors: Valanarasu S. , Chandramohan R. 
Published: June 2010

AbstractLayered intercalation compounds LiCo1‐xSnxO2 (x= 0 to 0.1) have been prepared using a simple combustion route method. X‐ray diffraction patterns and Laser Raman spectrum suggest that the synthesized materials had the R‐3m structure. Scanning electron images show that particles are well‐crystallized with a size distribution in the range of 50‐100 nm. The room temperature electrical conductivity of the sample increased with Sn content. For LiCo1‐xSnxO2(x = 0, 0.01, 0.03, 0.05 and 0.1), the first discharge capacity increased with increase in Sn content. Among these samples, LiCo0.95Sn0.05O2had produced the best performance of all others with a stable reversible capacity of 186 mAhg‐1 after 30 cycles. (© 2010 WILEY‐VCH Verlag GmbH & Co.

Synthesis and tribological properties of laminated Ti3SiC2 crystals
Authors: Wu Qiong , Li Changsheng , Tang Hua 
Published: June 2010

AbstractLaminated Ti3SiC2 crystals are prepared of Ti, Si, C and Al powders by the method of hot isostatic pressing with NaCl additive in argon at 1350 °C. The laminated morphology of Ti3SiC2 is presented through the SEM and TEM observations. The results of high resolution transmission electron microscope (HRTEM) and selected area electron diffraction (SAED) patterns combined, it can be seen that the layers are of Ti3SiC2 crystals. The growth mechanism of Ti3SiC2 crystals, controlled by two‐dimensional nucleation, is also explained. The tribological properties of Ti3SiC2 crystals as additives in HVI500 base oil are investigated by a UMT‐2 ball‐on‐plate friction and wear tester. The study shows that under determinate conditions, the friction coefficient of the base oil containing Ti3SiC2 crystals is lower than that of pure base oil, and it decreases with the increase of mass percent of Ti3SiC2 nanolayers when its proportion is lower than 5wt. %.

On the simulation of fast settling charge pump PLLs up to fourth order
Authors: Guermandi Marco , Franchi Eleonora , Gnudi Antonio 
Published: June 2010

AbstractIn this paper, we discuss three different models for the simulation of integer‐N charge‐pump phase‐locked loops (PLLs), namely the continuous‐time s‐domain and discrete time z‐domain approximations and the exact semi‐analytical time‐domain model. The limitations of the two approximated models are analyzed in terms of error in the computed settling time as a function of loop parameters, deriving practical conditions under which the different models are reliable for fast settling PLLs up to fourth order. Besides, output spectral purity analysis methods based upon the time‐domain model are introduced and the results are compared with those obtained by means of the s‐domain model in terms of phase noise and reference spur estimation. As a case study, we use the three models to analyze a fast switching PLL to be integrated in a frequency synthesizer for WiMedia MB‐OFDM UWB systems. Copyright © 2010 John Wiley & Sons, Ltd.
Zur Anwendbarkeit des vereinfachten Bemessungsverfahrens für Mauerwerksbauten in der Norddeutschen Tiefebene
Authors: Ortlepp Sebastian 
Published: June 2010

AbstractBei Bauvorhaben in der Norddeutschen Tiefebene sind bei der Lastermittlung besondere Regeln zu beachten. Der Grund hierfür ist, dass für die Schneelast ein zusätzlicher, außergewöhnlicher Lastfall mit 2,3‐fachem Einwirkungswert [1] berücksichtigt werden muss. Für die Zuordnung der Gebiete in der Norddeutschen Tiefebene zu Schneelastzonen wird auf die Musterliste der Technischen Baubestimmungen (MLTB [1]) bzw. die Liste der eingeführten Technischen Baubestimmungen (LTB [2]) der einzelnen Bundesländer verwiesen.Für die Anwendung des vereinfachten Verfahrens nach DIN 1053‐100 [3] gelten bestimmte Grenzen für Geometrie und Einwirkungen. Unter anderem darf dieses Berechnungsverfahren nur angewendet werden, wenn eine veränderliche Last auf einer Deckenplatte, welche auf einer Wand aus Mauerwerk gelagert ist, maximal 5 kN/m2 beträgt. Der vorliegende Beitrag zeigt die Randbedingungen, bei denen dieser außergewöhnliche Lastfall maßgebend wird und dass das vereinfachte Verfahren hier auch weiterhin angewendet werden darf.About the applicability of the simplified design method for mason ry buildings in the North German Plain.In construction projects in the North German Plain are special rules for determining the load to be observed. The reason for this is that to be expected for a snow load an additional, exceptional load case with 2.3‐fold value [1]. For the classification of areas in the North German Plain, the list of technical building regulations (MLTB [1] and [2]) of the various states is valid. The purposes of the simplified procedure provided in DIN 1053‐100 [3] is subject to certain limits on geo metry and loads. Among other things, this calculation method may be applied only if a variable load of less than 5 kN/m2 on a ceiling works, which is mounted on a wall of masonry. This paper describes the boundary conditions, for which the exceptional load case will prevail and when it is not important.
Schubtragfähigkeit von Mauerwerk aus Porenbeton‐Plansteinen und ‐Planelementen
Authors: Lohaus Ludger , Steinborn Thomas , Höveling Holger , Jäger Wolfram , Schöps Peter 
Published: June 2010

AbstractMauerwerkswände müssen neben Vertikallasten als platten‐ und scheibenförmige Bauteile auch horizontale Lasten aufnehmen und weiterleiten können. Die Neufassungen der DIN 1055 bzw. der DIN 4149 führten zu einer Erhöhung der anzusetzenden Horizontallasten aus Wind und Erdbeben und damit zu einer Erhöhung der Beanspruchung der aussteifenden Bauteile auf Schub.Im nachfolgend vorgestellten Forschungsvorhaben konnten vorhandene Reserven der Schubtragfähigkeit von Mauerwerk aus Porenbeton‐Plansteinen und ‐Planelementen durch Schubversuche an geschosshohen Mauerwerkswänden sowie durch begleitende Materialversuche, numerische Simulationen und Parameterstudien aufgezeigt werden.Durch die Versuche war es ebenfalls möglich, die vorhandene Datenbasis vor allem für Steine kleiner Festigkeiten (PP2) zu ergänzen und zu erweitern. Dadurch ist nun eine bessere statistische Anpassung der Bemessungsgleichung möglich. Für die Normung wurde ein Vorschlag erarbeitet. Sowohl im Versuch als auch in den Begleitrechnungen konnte für Wände mit vermörtelten Stoßfugen im Vergleich zu denen ohne eine Erhöhung der aufnehmbaren Horizontallasten nachgewiesen werden.Shear Loading Capacity of Aerated Autoclaved Concrete (AAC) Flat Block Masonry. Masonry walls should be able to carry and transfer horizontal loads in addition to vertical loads, due to their plate or panel form. The new versions of the DIN 1055 and DIN 4149 have led to an increasing of the assumed horizontal loads caused by wind and earthquakes, and thus to an increase in stress in the stiffening components that are designated for shear.The aim of the research project described below was to investigate the existing reserves in shear capacity of masonry made of aerated autoclaved concrete flat blocks. Therefore shear tests on masonry walls of a storey height were executed accompanied by material tests, numerical simulations and parameter studies. Furthermore it was possible to update and expand the existing data base particularly concerning blocks with lower strengths (PP2). Hence it is now possible to achieve a better statistical adjustment to the design equations. A proposal for standardization was also developed. From the investigations and the accompanying calculations, it was determined that walls with mortared butt joints have a higher horizontal load carrying capacity in comparison with those without.

Control of the misuse of bromide in horses
Authors: Ho Emmie N. M. , Wan Terence S. M. , Wong April S. Y. , Lam Kenneth K. H. , Schiff Peter J. , Stewart Brian D. 
Published: June 2010

AbstractBromide is a sedative hypnotic. Due to its potential use as a sedative or calmative agent in competition horses, a method to control bromide is needed. Colorimetric method had been employed in the authors' laboratory from 2003 for the semi‐quantification of bromide in equine plasma samples. However, the method was found to be highly susceptible to matrix interference, and was replaced in 2008 with a more reliable inductively coupled plasma‐mass spectrometry (ICP/MS) method. Equine plasma was protein‐precipitated using trichloroacetic acid, diluted with nitric acid, and then submitted directly to ICP/MS analysis.Since bromide is naturally occurring in equine plasma, a threshold is necessary to control its misuse in horses. Based on population studies (n = 325), a threshold of 90 µg/mL was proposed (with a risk factor of less than 1 in 10 000). Using the ICP/MS screening method, equine plasma samples with bromide greater than 85 µg/mL would be further quantified using the more accurate ICP/MS standard addition method. Confirmation of bromide was achieved by gas chromatography‐mass spectrometry (GC‐MS), with the bromide detected as its pentafluorobenzyl derivative. A sample is considered positive if its plasma bromide concentration exceeds the threshold (90 µg/mL) plus the measurement uncertainty of the quantification method (8 µg/mL at 99% 1‐tailed confidence level) and its presence is confirmed using the GC‐MS method.Following oral administration of potassium bromide (60 g each) to two geldings, plasma bromide levels peaked after approximately 2 hours at about 300 µg/mL, and then remained above the threshold for 8 and 13 days respectively.

The Chemical Behavior of 3,4‐Benzocycloocten‐1,5‐diyne
Authors: Werner Christian , Hopf Henning , Grunenberg Jörg , Jones Peter G. 
Published: June 2010

AbstractThe title compound 3,4‐benzocycloocten‐1,5‐diyne (1) is a highly reactive hydrocarbon that has been shown to undergo addition reactions with tetraphenyl‐cyclopentadienone(tetracyclone) to the 2:1 adduct 6, with octacarbonyldicobalt to the bis metal complex 7, with lithium aluminium hydride to the bis diene 9, and with various electrophilic reagents. In these latter cases cationic intermediates are generated from 1 and a transannular cyclization takes place leading to novel derivatives of 1,2‐dihydropentalene (31, 32, 35, 36, 43, 44).
Chiral Phosphanylferrocenecarboxamides with Amino Acid Pendant Groups as Ligands for Cu‐Mediated Asymmetric Conjugate Additions of Diethylzinc to Chalcones – Structural Characterisation of Precursors to the Cu Catalyst
Authors: Tauchman Jiří , Císařová Ivana , Štěpnička Petr 
Published: June 2010

AbstractA series of chiral phosphanylferrocenecarboxamides was prepared by treatment of either 1′‐(diphenylphosphanyl)ferrocene‐1‐carboxylic acid (Hdpf) or its planar‐chiral 1,2‐isomers with amino acid methyl esters in the presence of peptide coupling agents. The compounds were characterised by spectroscopic methods, and the crystal structure of one representative was determined by X‐ray diffraction. Catalytic testing of these donors in Cu‐catalysed asymmetric conjugate additions of diethylzinc to chalcones revealed that the reaction outcomes were highly sensitive to the ligand structure and the reaction conditions (copper source and solvent), whereas the chalcone substituents (Me, MeO, or Cl in positions 4 or 4′) had a less pronounced influence. Compounds based on Hdpf proved to be better ligands than their planar‐chiral analogues. Under optimised conditions, the reactionwith L‐valine–Hdpf conjugate, (S)‐Ph2PfcCONHCH(CHMe2)CO2Me (fc = ferrocene‐1,1′‐diyl) and unsubstituted chalcone gave the alkylation product with complete conversion (20 °C/4 h) and in 87 % ee. The catalytic behaviour of the amidophosphane ligands was correlated to the results of amodel coordination study and the crystal structure of [Cu(Ph2PfcCONHCH2CO2Me)2](CF3SO3)·2CHCl3.
