Authors: Amini Malihe , Younesi Habibollah
Published: September 2009

In this study, the biosorption of Cd(II), Ni(II) and Pb(II) on Aspergillus niger in a batch system was investigated, and optimal condition determined by means of central composite design (CCD) under response surface methodology (RSM). Biomass inactivated by heat and pretreated by alkali solution was used in the determination of optimal conditions. The effect of initial solution pH, biomass dose and initial ion concentration on the removal efficiency of metal ions by A. niger was optimized using a design of experiment (DOE) method. Experimental results indicated that the optimal conditions for biosorption were 5.22 g/L, 89.93 mg/L and 6.01 for biomass dose, initial ion concentration and solution pH, respectively. Enhancement of metal biosorption capacity of the dried biomass by pretreatment with sodium hydroxide was observed. Maximal removal efficiencies for Cd(II), Ni(III) and Pb(II) ions of 98, 80 and 99% were achieved, respectively. The biosorption capacity of A. niger biomass obtained for Cd(II), Ni(II) and Pb(II) ions was 2.2, 1.6 and 4.7 mg/g, respectively. According to these observations the fungal biomass of A. niger is a suitable biosorbent for the removal of heavy metals from aqueous solutions. Multiple response optimization was applied to the experimental data to discover the optimal conditions for a set of responses, simultaneously, by using a desirability function.

Published: September 2009

The direct low‐temperature oxidation of methane to methanol is demonstrated on a highly active homogeneous molecular catalyst system and on heterogeneous molecular catalysts based on polymeric materials possessing ligand motifs within the material structure. The N‐(2‐methylpropyl)‐4,5‐diazacarbazolyl‐dichloro‐platinum(II) complex reaches significantly higher activity compared to the well‐known Periana system and allows first conclusions on electronic and structural requirements for high catalytic activity in this reaction. Interestingly, comparable activities could be achieved utilizing a platinum modified poly(benzimidazole) material, which demonstrates for the first time a solid catalyst with superior activity compared to the Periana system. Although the material shows platinum leaching, improved activity and altered electronic properties, compared to the conventional Periana system, support the proposed conclusions on structure–activity relationships. In comparison, platinum modified triazine‐based catalysts show lower catalytic activity, but rather stable platinum coordination even after several catalytic cycles. Based on these systems, further development of improved solid catalysts for the direct low‐temperature oxidation of methane to methanol is feasible.
Sustainable Chemistry Metrics
Authors: Calvo‐Flores Francisco García
Published: September 2009

Green chemistry has developed mathematical parameters to describe the sustainability of chemical reactions and processes, in order to quantify their environmental impact. These parameters are related to mass and energy magnitudes, and enable analyses and numerical diagnoses of chemical reactions. The environmental impact factor (E factor), atom economy, and reaction mass efficiency have been the most influential metrics, and they are interconnected by mathematical equations. The ecodesign concept must also be considered for complex industrial syntheses, as a part of the sustainability of manufacturing processes. The aim of this Concept article is to identify the main parameters for evaluating undesirable environmental consequences.
A new ICI mitigation method with generalized data‐allocation for OFDM systems
Authors: Wu Jiun‐Ming , Chen Chun‐Chyuan
Published: September 2009

This paper describes an ICI mitigation method based on the generalized data‐allocation of (1, −β) for orthogonal frequency division multiplexing systems. To improve the performance of the ICI mitigation for the higher‐frequency offset, we propose an efficient search algorithm to generate the sub‐optimal parameter β for maximizing the carrier‐to‐interference ratio (CIR). The CIR and bit error rate performances of the proposed method were derived in this paper. The performances with different carrier frequency offset scenarios were evaluated by computer simulations. According to the simulation results, the performance of the proposed ICI mitigation scheme is better than that of the conventional ICI self‐cancellation scheme and is nearly the same as that of the ICI self‐cancellation scheme for the optimal parameter β. Additionally, the proposed ICI mitigation scheme has a dramatically reduced hardware complexity in comparison with the ICI self‐cancellation scheme for the optimal parameter β.

Published: September 2009

Background

Diabetes is a risk factor for coronary heart disease (CHD) but CHD does not occur in all diabetic individuals. The goal of this study was to assess the relationship between family history of myocardial infarction (MI) and incident CHD in diabetic postmenopausal women.

Methods

We conducted a prospective cohort study among 2642 diabetic postmenopausal women without CHD at baseline in the Women's Health Initiative Observational Study. Family history was defined as a proband report of MI in first‐degree relatives. Incident CHD was defined as non‐fatal MI, coronary revascularization, or CHD death.

Results

During 7.3 ( ± 1.8) years of follow‐up, 14.3% of the participants had incident CHD. The risk of incident CHD was 50% higher (HR = 1.50, 95% CI: 1.20–1.87, p = 0.0003) in those with a family history of an MI in at least one first‐degree relative, and 79% higher (HR = 1.79, 95% CI: 1.36–2.35, P < 0.0001) if two or more first‐degree relatives had an MI, compared to participants without a family history, after adjustment for covariates. The CHD risk increased with elevated systolic blood pressure (SBP) (HR = 1.01, 95% CI: 1.003–1.02, p = 0.001) but decreased with elevated diastolic BP (HR = 0.98, 95% CI: 0.97–0.999, p = 0.005) and with two or more episodes per week of physical activity (HR = 0.70, 95% CI: 0.52–0.93, p = 0.02).

Conclusions

The results suggest that a family history of MI predicts CHD in diabetic postmenopausal women. Close attention should be paid to BP control and physical activity in these women. Copyright © 2009 John Wiley & Sons, Ltd.
Synthesis and Reactivity of an Aminocarbene Osmium Complex Formed by Double C–H Activation of a NCH3 Unit
Authors: Richter Birgit , Werner Helmut
Published: September 2009

The reaction of [OsCl2(PPh3)3] (1) with iPr2PCH2CH2NMe2 in 2‐propanol under reflux affords the Fischer‐type aminocarbene complex cis,cis‐[OsCl2{κ2(C,P)‐CHN(CH3)CH2CH2PiPr2}{κ2(P,N)‐iPr2PCH2CH2NMe2}] (2) by double C–H activation of one NCH3 group. While treatment of 2 with phenylacetylene leads to the vinylidene complex cis,trans‐[OsCl2(C=CHPh){κ2(C,P)‐CHN(CH3)CH2CH2PiPr2}{κ(P)‐iPr2PCH2CH2NMe2}] (3) by partial opening of the P,N‐chelate bond, the reaction of 2 with CO and CNtBu gives rise to ionic compounds of type [OsCl(L){κ2(C,P)‐CHN(CH3)CH2CH2PiPr2}{κ2(P,N)‐iPr2PCH2CH2OMe}]Cl (4: L = CO, 5: L = CNtBu) by substitution of one chloro ligand.

Authors: Turcu Mihaela C. , Rantapaju Maria , Kanerva Liisa T.
Published: September 2009

The kinetic resolution of three dorzolamide intermediates has been studied in the presence of Burkholderia cepacia lipase in organic solvents. All the stereoisomers of 6‐methyl‐5,6‐dihydro‐4H‐thieno[2,3‐b]thiopyran‐4‐ol were prepared starting from the racemic cis‐dihydrothiopyranol intermediate giving first the 4R,6S and 4S,6R enantiomers. Subsequent epimerization and purification of the trans enantiomers by enzymatic acylation or alcoholysis then gave the cis enantiomers. The cis‐4‐hydroxy‐6‐methyl‐5,6‐dihydro‐4H‐thieno[2,3‐b]thiopyran 7,7‐dioxide enantiomers were also prepared by enzymatic kinetic resolution. The kinetic resolution of ethyl 3‐(2‐thienylthio)butanoate with lipases gave moderate enantioselectivities but the method was not used on a preparative scale with this substrate.

Published: September 2009

The mechanism of the sulfuric acid‐catalyzed acetolysis of methyl 2,3,5‐tri‐O‐acetyl‐ and methyl 2,3,5‐tri‐O‐benzoyl‐L‐ribofuranosides and the accompanying anomerization of both the starting material and the 1,2,3,5‐tetra‐O‐acetyl‐ and 1‐O‐acetyl‐2,3,5‐tri‐O‐benzoyl‐L‐ribofuranoses formed was investigated. The progress of the reactions was followed by 1H NMR spectroscopy and the rate constants for the reactions were determined for a proposed kinetic model. The role of H+ and Ac+ as the catalytically active species was clarified, proving that the anomerization of the acylated methyl furanosides is activated by protonation, while, on the contrary, the anomerization of the 1‐O‐acetyl ribofuranoses is activated by the acetyl cation. The anomerization of the acylated methyl furanosides was verified to be activated on the ring oxygen leading to endocyclic CO‐bond rupture while the 1‐O‐acetyl ribofuranoses are activated on the acetyloxy group on C(1) leading to exocyclic cleavage.(© Wiley‐VCH Verlag GmbH & Co.

Authors: Vigl Alois , Gerstner Reinhold
Published: September 2009

Injection grouting by various methods is of fundamental importance for the construction of pressure tunnels and demands corresponding attention from designers and also from contractors. Pressure tunnel for the sake of this article means the low‐pressure sections of the water supply to hydropower stations upstream of the surge chamber with an internal pressure of up to approx. 200 m WS (20 bar). The article deals principally with grouting used with lining systems consisting of precast concrete segments. Specific aspects concerning the grouting of in‐situ concrete linings, foils or steel liners are only included incidentally.

Injektionen unterschiedlicher Art sind im Druckstollenbau von grundlegender Bedeutung und verdienen sowohl in der Planung als auch in der Ausführung eine entsprechende Beachtung. Als Druckstollen wird im Rahmen dieser Darstellung der Niederdruckabschnitt der Triebwasserführung von Wasserkraftanlagen vor dem Wasserschloss, mit einem Innendruck bis ca. 200 m WS (20 bar) verstanden. In erster Linie werden Injektionen behandelt, die bei Auskleidungssystemen mit Betonfertigteilen (Tübbingsystemen) Anwendung finden. Spezifische Aspekte von Injektionen bei Ortbeton‐Auskleidungen, Folien oder Panzerungen werden nur am Rande mit einbezogen.

Published: September 2009

The Pfaendertunnel bypasses the residential area of the city of Bregenz at the northern part of the A14 Rheintal motorway. The alignment of the 2nd bore of the Pfaendertunnel runs for over 6.5 km under the Pfaender mountain‐massif, 70 m west of the existing bore. The route runs through geology described as the “Standing midland molasse”, a sequence of beds from the Neogene period (young Tertiary), which today mostly consisting of conglomerate, sandstones, marl‐sandstones, marl and clay‐marl. The second bore will be excavated continuously by a shielded tunnel boring machine, opening from the north starter‐tunnel to the existing bore at the south. The standard cross‐section of the tunnel will be circular (bored diameter 11.92 m) with external diameter 11.62 m segmental concrete lining. The paper deals with the main issues related to the design of the alternative TBM tunnelling‐tender taking into account the swelling tendency of the rock mass and also deals with the construction‐issues of the first road tunnel in Austria being built by the use of a TBM. During initial TBM‐drive in the starter‐tunnel the machine sagged into loose ground.. The problem of driving a TBM into divided cross sections (bench and invert sections without top‐heading) into soft ground and the solution adopted on site is discussed.

Der Pfändertunnel stellt, als nördlichster Teil der A14 Rheintal Autobahn, die Umfahrung des Siedlungsraums Bregenz dar. Die Achse der zweiten Röhre des Pfändertunnels erstreckt sich über 6,5 km unterhalb des Pfändermassives, 70 m westlich der Bestandsröhre. Die Trasse durchfährt die so genannte aufgerichtete mittelländische Molasse, eine Schichtfolge des Neogen (Jungtertiär) die heute als Konglomerate, Sandsteine, Mergelsandsteine, Mergel und Tonmergel vorliegt. Der Ausbruch der zweiten Röhre wird im kontinuierlichen Vortrieb, beginnend bei der Startstrecke Nord bis zur Bestandsröhre im Süden, mit einer Tunnelbohrmaschine mit Schild aufgefahren. Als Regelquerschnitt des Tunnelbauwerks wird ein Kreisquerschnitt mit Tübbingausbau mit einem Außendurchmesser von 11,62 m (Bohrdurchmesser 11,92 m) ausgeführt. Der Beitrag behandelt die Planungsschwerpunkte in Bezug auf das Alternativangebot TVM‐Vortrieb unter Berücksichtigung der Quellproblematik des Gebirges sowie die Bauausführung des ersten Straßentunnels mittels einer TVM in Österreich. Beim Einfahren in die Startstrecke Nord kam es zum Absinken der TVM im Lockermaterial. Die Einfahrtsproblematik im Lockermaterial bei einem halb aufzufahrenden Querschnitt (Strosse und Sohle) und die gewählten Lösungen werden erläutert.
