A colorimetric chiral sensor based on chiral crown ether for the recognition of the two enantiomers of primary amino alcohols and amines
Authors: Cho Eun Na Rae , Li Yinan , Kim Hee Jin , Hyun Myung Ho 
Published: December 2010

AbstractA new colorimetric chiral sensor material consisting of three different functional sites such as chromophore (2,4‐dinitrophenylazophenol dye), binding site (crown ether), and chiral barrier (3,3′‐diphenyl‐1,1′‐binaphthyl group) was prepared and applied to the recognition of the two enantiomers of primary amino alcohols and amines. Among five primary amino alcohols and two primary amines tested, the two enantiomers of phenylalaninol show the highest difference in the absorption maximum wavelength (Δλmax = 43.5 nm) and in the association constants (KS/KR = 2.51) upon complexation with the colorimetric chiral sensor material and, consequently, the two enantiomers of phenylalaninol were clearly distinguished from each other by the color difference.

Accumulation of Heavy Metals by Chickpea Grown in Fly Ash Treated Soil: Effect on Antioxidants
Authors: Pandey Vimal Chandra , Singh Jay Shankar , Kumar Akhilesh , Tewari D. D. 
Published: December 2010

AbstractChickpea grown in fly ash (FA) treated soil (25, 50, and 100% FA) was used to evaluate the effect of FA on antioxidants, metal concentration (Fe, Zn, Cu, Cr, and Cd), photosynthetic pigments (chlorophyll a (chl‐a), chlorophyll b (chl‐b), total chlorophyll (total chl), and carotenoids), growth and yield performance. All antioxidants in roots, shoots and leaves of chickpea increase with increasing FA doses to combat FA stress. The activities of antioxidants were more in the root tissues to cope with stress induced in the plants as compared to shoot and leaf. Concentration of metals was found maximum in roots than the shoots and seeds. The highest concentration of Fe and lowest level of Cd were recorded in all treatments of FA for different parts of the plant. The treated crop showed reduced level of chlorophyll but enhanced level of carotenoids and protein. However, root length, number of nodules and biomass in 25 and 50% FA treatments did not differ significantly in comparison to respective control plants. These results suggest that heavy metals of FA causes oxidative stress in this crop and the antioxidant enzymes could help a pivotal role against oxidative injury.
Amendment of Copper Toxicity in Alluvial Soil Using Iron: Effect on Growth and Yield of Triticum aestivum L.
Authors: Singh Dharam 
Published: December 2010

AbstractPot experiments were conducted in glasshouse under controlled conditions. The effect of copper in alluvial soil on the growth and yield of Triticum aestivum L. (wheat) was worked out. Copper was applied in soil at 5–100 mg L−1, along with iron supplement. Inhibitory response of copper was significant (p < 0.05) confirmed by the plant growth parameters viz., plant height, fresh and dry weight, moisture content, pigment contents, protein, sugar contents followed by increased catalase and peroxidase activity in the harvest at 30, 60, and 90 days, of treatment, respectively. The plants grown on copper treated soil along with 5 mg L−1 Cu and iron application showed significant effects (p < 0.05) regarding the increase in plant biomass, plant height (shoot only), pigment contents, protein, sugar contents, grain yield followed by decreased catalase and peroxidase activity in wheat after 30, 60, and 90 days of treatment, respectively. The accumulation of metal in plant tissues was found in order of Fe > Cu coupled by less translocation in grain as compared to the whole plant.

Published: December 2010

AbstractThe removal of chemical oxygen demand (COD) and phenol from olive oil mill wastewaters (OOMW) was investigated experimentally by using conventional Fenton (CFP) and Fenton type processes (FTP) with zero valent iron (ZVI). Different operational parameters such as initial pH, Fe2+, Fe0, and H2O2 concentrations were examined. Kinetic studies in terms of COD and phenol removals for both CFP and FTP were performed. The original pH value (4.6) of OOMW for CFP was found as the optimum pH. The determined optimum conditions are [Fe2+] = 1500 mg L−1, [H2O2] = 1750 mg L−1, and pH = 4.6 for CFP; [Fe0] = 2000 mg L−1, [H2O2] = 2000 mg L−1, and pH = 3 for FTP. 82.4% COD and 62% phenol removals were performed under the optimum conditions by CFP, while 82% COD and 63.4% phenol were removed by FTP. According to the results of kinetic studies, it was observed that COD and phenol were removed by FTP more rapidly, compared to CFP. Consequently, it was determined that both CFP and FTP were effective processes for the pretreatment of OOMW.

AbstractThe appearance of group 1 CD1 proteins (CD1a, CD1b and CD1c) on maturing myeloid DC is a key event that converts myeloid DC to effective lipid APC. Here, we show that Borrelia burgdorferi, the causative agent of Lyme disease, triggers appearance of group 1 CD1 proteins at high density on the surface of human myeloid DC during infection. Within human skin, CD1b and CD1c expression was low or absent prior to infection, but increased significantly after experimental infections and in erythema migrans lesions from Lyme disease patients. The induction of CD1 was initiated by borrelial lipids acting through TLR‐2 within minutes, but required 3 days for maximum effect. The delay in CD1 protein appearance involved a multi‐step process whereby TLR‐2 stimulated cells release soluble factors, which are sufficient to transfer the CD1‐inducing effect in trans to other cells. Analysis of these soluble factors identified IL‐1β as a previously unknown pathway leading to group 1 CD1 protein function. This study establishes that upregulation of group 1 CD1 proteins is an early event in B. burgdorferi infection and suggests a stepwise mechanism whereby bacterial cell walls, TLR activation and cytokine release cause DC precursors to express group 1 CD1 proteins.

Published: December 2010

AbstractA series of novel complexes [Ln2(N3)(nic)2(OH)3(Hnic)(H2O)]n (Ln = YIII 1 and GdIII 2; Hnic = nicotinic acid) and [Sm4(N3)2(nic)4(OH)6(Hnic)2(H2O)2]n (3) have been hydrothermally synthesized and structurally characterized by single‐crystal X‐ray analysis. Complexes 1, 2 and 3 have similar structures and consist of [Ln2(N3)(nic)2(OH)3(Hnic)(H2O)] units that are linked to neighboring units through end‐on azido, μ2 and μ3 hydroxo, and bridging carboxylato groups to form 1D infinite chains. In all the complexes the 1D chains propagate parallel to crystallographic a‐axis to give rise to a ribbon‐like chain structure. All the compounds exhibit excellent catalytic performance in olefin epoxidation reactions, which is reflected in high turnover numbers. Good expoxide selectivity was obtained in the cases of cyclooctene and 1‐hexene. The possibility of easy recycling makes these catalysts highly promising candidates for addressing industrial needs and environmental concerns.

AbstractThe dinuclear complexes [Cu2(R‐pybox)2][PF6]2 {R‐pybox = 2,6‐bis[4′‐(S)‐isopropyloxazolin‐2′‐yl]pyridine for (S,S)‐iPr‐pybox (1) and 2,6‐bis[4′‐(R)‐phenyloxazolin‐2′‐yl]pyridine for (R,R)‐Ph‐pybox (2)} are very efficient precursors for the synthesis of dinuclear and mononuclear derivatives containing isocyanide or phosphane ligands. The reaction of 1 and 2 with the isocyanides (CNBn or CNCy) resulted in the synthesis of the dinuclear derivatives [Cu2(R‐pybox)2(CNBn)2][PF6]2 [R‐pybox = (S,S)‐iPr‐pybox (3), (R,R)‐Ph‐pybox (4)] and [Cu2(R‐pybox)2(CNCy)2][PF6]2 [R‐pybox = (S,S)‐iPr‐pybox (5), (R,R)‐Ph‐pybox (6)]. When the reaction was carried out with the monodentate (PMePh2, PPh3) and the bidentate phosphanes [dppm, dppf, (S)‐peap] the mononuclear complexes [Cu(R‐pybox)(PRPh2)2][PF6] [R‐pybox = (S,S)‐iPr‐pybox, R = Me(7), Ph (8); R‐pybox = (R,R)‐Ph‐pybox, R = Ph (9)], [Cu(R‐pybox){(S)‐peap}][PF6] [R‐pybox = (S,S)‐iPr‐pybox (11), (R,R)‐Ph‐pybox (12)], and [Cu(R‐pybox)(dppf)][PF6] [R‐pybox = (S,S)‐iPr‐pybox (13), (R,R)‐Ph‐pybox (14)] and the dinuclear complex [Cu2{(S,S)‐iPr‐pybox}(μ‐dppm)2][PF6]2 (10) were obtained, respectively. The structures of complexes 3, 7, 10, and 13 have been resolved by X‐ray diffraction methods and by 1D, 2D, and DOSY NMR spectroscopy measurements. The 1H, 31P, and 19F DOSY NMR spectroscopic experiments provided evidence that the solid‐state nuclearity of compounds 3, 7, 10, and 13 is maintained in solution and confirmed that these ionic compounds exist in solution as stable, discrete, cationic complexes.

Published: December 2010

AbstractThe paper summarizes the results of a recent industry supported research and development study in which a novel framework for evaluating meaningful power system reliability and quality indices was developed and applied. The system‐wide integrated performance indices are capable of addressing and revealing areas of deficiencies and bottle‐necks as well as redundancies in the composite generation–transmission–demand structure of large‐scale power grids. The novel technique utilizes a basic linear programming formulation, which offers a general and comprehensive framework to assess the harmony and compatibility of generation, transmission, and demand in a power system. Practical application to a portion of the Saudi power grid is also presented in the paper for demonstration purposes. Copyright © 2010 John Wiley & Sons, Ltd.
A novel Multi‐objective Fuzzy Adaptive Chaotic PSO algorithm for Optimal Operation Management of distribution network with regard to fuel cell power plants
Authors: Niknam Taher , Zeinoddini Meymand Hamed , Doagou Mojarrad Hasan 
Published: December 2010

AbstractA new Multi‐objective Fuzzy Adaptive Chaotic particle swarm optimization (MFACPSO) evolutionary algorithm for the Multi‐objective daily Optimal Operation Management (MOOM) problem with regard to fuel cell power plants (FCPPs) in distribution system is presented in this paper. The purposes of the MOOM problem are to minimize the total electrical energy losses, the total electrical energy cost, and the total pollutant emission produced by sources. Conventional algorithms for solving the multi‐objective optimization problems convert the multiple objectives into a single objective using a vector of the user‐predefined weights. This conversion has several defects. For instance, the final solution of the algorithms greatly depends on the values of the weights and it also loses some information in the conversion and this strategy is not expected to provide a robust solution. The proposed algorithm maintains a finite‐sized repository of non‐dominated solutions which gets iteratively updated in the presence of new solutions. Since the objective functions are non‐commensurable, a fuzzy clustering technique is used to control the size of the repository within the limits. The proposed algorithm is tested on two distribution test feeders and the results demonstrate the capabilities of the proposed approach to generate a set of well‐distributed Pareto‐optimal non‐dominated solutions of the MOOM problem. The comparison with the different reported techniques demonstrates the superiority of the proposed MFACPSO in terms of the diversity of the Pareto‐optimal solutions obtained. In addition, the results confirm the potential of the proposed technique to solve the MOOM problem and produce high‐quality non‐dominated solutions. Copyright © 2010 John Wiley & Sons, Ltd.

AbstractBackgroundThe purpose of this prospective study was to assess the quality of life (QOL) and oral functioning of patients with oral cancer up to 5 years after prosthodontic rehabilitation with mandibular implant‐retained overdentures.MethodsFifty patients who had received implants during ablative surgery were evaluated by standardized questionnaires before and after oncological and prosthetic treatment.ResultsIn 20 of 24 surviving patients, the dentures were functional after 5 years. In these survivors, oral function remained unchanged during this period. In the 6 patients with concurrent comorbidity, global health and QOL had deteriorated, while in the patients without comorbidity, global health and QOL were very high. Five‐year survivors had a higher global health and better oral functioning at the 1‐year evaluation than nonsurvivors.ConclusionOral function and denture satisfaction were high and did not change over time for survivors. Deterioration in overall global health and QOL was associated with concurrent comorbidity. Head Neck, 2011

THE IMPACT OF AID ON BUREAUCRATIC QUALITY: DOES THE MODE OF DELIVERY MATTER?
Authors: Selaya Pablo , Thiele Rainer 
Published: December 2010

AbstractWe show that the impact of foreign aid on bureaucratic quality in recipient countries varies with the mode of delivery. Specifically, grants are found to impair the functioning of the bureaucracy, whereas loans are not. The negative impact of grants is larger when they are given as budget support rather than as assistance for specific projects or for programmes in general. Our results thus suggest that the probability of adverse effects rises with the degree of discretion recipients have over the incoming resources, which is in conflict with donors' recent emphasis on strengthening local ownership by limiting the conditions attached to foreign aid.

Rudimentary pedal grasping in mice and implications for terminal branch arboreal quadrupedalism
Authors: Byron Craig , Kunz Hawley , Matuszek Heather , Lewis Stephanie , Van Valkinburgh Daniel 
Published: December 2010

AbstractWe use an outbred laboratory mouse strain (ICR/CD‐1, Charles River Laboratories, Inc.) to model a type of preprimate locomotion associated with rudimentary pedal grasping. Ten male mice were assigned to either control or climbing groups (n = 5 per group). Climbing mice lived within a specialized terrarium that included ∼7.5 m of thin branches (5 and 10 cm long) with a thickness of 3.3mm, arranged in a reticulated canopy. Food, water, and a nest site were placed among the branches. To discourage mice from palmigrade or digitigrade locomotion, the floor of the terrarium was flooded with a few centimeters of water. Climbing mice were placed in this setting upon weaning and reared for 3 months until they were mature in size. Litter, and age‐matched controls were also maintained for comparison with climbers. Climbing mice quickly acclimated to the requirements of the fine‐branch model using the foot and tail for grasping and balance. At maturity, climbing and control mice exhibited minor, but significant, morphological plasticity. For climbers, this includes a greater angle of the femoral neck, larger patellar groove index, relatively shorter talar neck length, and more circular talar head aspect ratio (P < 0.10). Climbers also exhibit increased curvature of the distal third metacarpal, decreased talar head angle, and relatively longer caudal vertebrae transverse processes (P < 0.05). These results in a small‐bodied eutherian mammal suggest that facultative hallucial opposability and coordinated tail use enable a kind of grasping active arboreal quadrupedality relevant to the latest stages of pre‐euarchontan evolution. In light of these data, we hypothesize that a unique advantage of mouse‐sized mammals is that they exhibit a highly flexible body plan allowing them to engage in a diverse array of anatomical positions without requiring specific limb morphologies.

The sensitivity of climate response to the wintertime Niño3.4 sea surface temperature anomalies of 1855–2002
Authors: Bulić Ivana Herceg 
Published: December 2010

AbstractThe sensitivity of winter atmosphere to ENSO forcing is analysed from an ensemble of integrations forced with observed monthly sea‐surface temperatures (SSTs) for the period 1854–2002 with particular interest on the North Atlantic European (NAE) region. A categorisation into warm and cold events, according to the strength of Niño3.4 index, is performed providing main features of simulated atmospheric response to ENSO forcing. A symmetry in a spatial pattern of the atmospheric response to warm and cold phase is found, but with stronger amplitude for warm events. An additional experiment with SST forcing restricted to the tropical Pacific confirmed that atmospheric variability over the Northern Hemisphere is considerably affected by ENSO, even over the distant NAE region.Signals calculated over the Niño3.4, Pacific‐North American (PNA) and NAE regions are analysed as functions of the amplitude of the winter (JFM) SST anomalies in the Niño3.4 region. Both the precipitation and large‐scale circulation signals over the Niño3.4 and PNA regions gradually increase with the intensity of SST forcing. However, an asymmetry in amplitude of atmospheric response respecting the polarity of the tropical SST anomalies is found. The tropical and PNA signals associated with warm ENSO events are found to be stronger than the signals related to the cold events. A saturation effect is noticed for the cold events. No such evident characteristics are obtained for the NAE region, but the results imply discernible ENSO impact on atmospheric signals over that region.Using a correlation coefficient approach, it is shown that the JFM Niño3.4 SST anomaly affects not only the atmospheric response in the simultaneous season, but also during the next few seasons. Significant correlations between the strength of ENSO and the signals are found for the Niño3.4 and PNA regions. Although with smaller absolute values, statistically significant correlations are also found for the NAE region. Copyright © 2010 Royal Meteorological Society
