Homotopy analysis of heat and mass transfer boundary layer flow through a non‐porous channel with chemical reaction and heat generation
Authors: Shateyi S. , Motsa S. S. , Sibanda P.
Published: August 2010

This paper describes the two‐dimensional flow of an incompressible viscous fluid through a non‐porous channel with heat generation and a chemical reaction. Employing similarity transformations the governing non‐linear partial differential equations are solved both analytically and numerically. Analytically, we used the homotopy analysis method and numerically, we used the Matlab in‐built boundary value solver bvp4c. The effects of the Reynolds number Re, the Eckert number Ec, heat generation parameter δ, chemical reaction parameter γ, and the local Grashof number Gc on the velocity, temperature, and concentration fields are shown through tables and graphs and discussed.
A model of steady viscous flow of a micropolar fluid driven by injection or suction between a porous disk and a non‐porous disk using a novel numerical technique
Authors: Motsa S. S. , Shateyi S. , Sibanda P.
Published: August 2010

In this study, we solve the problem of steady viscous flow of a micropolar fluid driven by injection between two porous disks using novel spectral modification of the homotopy analysis method (SHAM). The effects of Reynold's number (Re), and the micropolar parameters (c1, c2, c3) on the velocity profiles and microrotation are shown through tables and graphed and then discussed.
Mathematical modelling of fluidized‐bed reactors for non‐catalytic gas–solid reactions
Authors: Maroufi S. , Khoshandam B. , Kumar R. V.
Published: August 2010

Mathematical modelling of a continuous fluidized‐bed reactor has been carried out for non‐catalytic gas–solid reactions. The two‐phase bubbling bed model has been used and the elutriation phenomenon for the fine particles has been investigated. The feed stream consisting particles with size distribution and reversible or irreversible first‐order kinetics can be treated by the model. The reduction behaviour of solid reactants was described by the grain model. A program was developed in MATLAB software for solving the governing equations at conditions of different temperatures and pressures. The model was validated using experimental data and simulation results available in the literature for the iron ore reduction with a gas mixture containing hydrogen [Srinivasan and Staffansson, Chem. Eng. Sci. 45(5), 1253–1265 (1990)]. The mathematical modelling was also used for predicting the extent of reaction for reduction of cobalt oxide by methane.

Published: August 2010

Nanocomposites of LDPE/LLDPE/nanoclay have been prepared using a lab‐scale co‐rotating twin screw extruder. Using XRD, tensile testing, AFM, TGA, effects of some material properties and one processing parameter on mechanical and thermal properties of the prepared nanocomposites were evaluated. Tensile properties indicated that all the prepared nanocomposites exhibited a significant improvement in elastic modulus and toughness compared to pristine LDPE/LLDPE blends of the same composition. Thermal stability of nanocomposites in the air and nitrogen atmosphere was improved. XRD patterns and AFM micrographs showed semi‐exfoliated and intercalated microstructures for the prepared nanocomposites with different orders of mixing.

The solvent‐free O‐acylation of some alcohols with benzoyl chloride was carried out to the corresponding benzoylated products in good to excellent yields by the mediation of a catalytic amount (5 mol%) of the commercially available and inexpensive zinc oxide in short reaction times. This methodology represents an eco‐friendly and simple catalytic alternative for benzoylation of primary, secondary, tertiary, and benzylic alcohols with ZnO. This catalytic system was homogeneous because of high solubility of zinc oxide in the reaction medium. Findings showed that ZnO was dissolved in hydrochloric acid, created in situ, after a few minutes. Although, others argued on the catalytic role of solid phase zinc oxide under a heterogeneous condition, it is not surprising to emphasize on the catalytic function of Zn2+ in the benzoylation of alcohols under homogeneous reaction conditions. Zinc oxide served as pre‐catalyst to form Zn2+, as the catalytically active species.

Injecting liquid CO2 into deep‐sea sediments below ca. 3 km of seawater has been suggested for the permanent storage of anthropogenic CO2. At the pressures and temperature found below 3 km of seawater, CO2 becomes denser than seawater and so is likely to remain permanently sequestered in the sediment. Deepwater engineering, however, is expensive and seawater depths of greater than 3 km are often only reached far from shore. Here, we consider the less expensive alternative of injecting CO2 into marine sediments at depths shallower than required for denser‐than‐seawater CO2 storage. We compare the mobility of liquid CO2 that has been injected into deep‐sea reservoirs with the mobility of supercritical CO2 that has been injected into geologically equivalent (i.e., identical porosity, permeability, and effective stress) reservoirs with terrestrial pressure and temperature conditions. We demonstrate that buoyant liquid CO2 with a density of about 90 % that of seawater is sufficiently immobile that it can be considered trapped by gravity and capillarity. In contrast, supercritical CO2 under typical terrestrial conditions is highly mobile and only trapped by the appropriate confining layer in either a structural or stratigraphic trap. As a result of its very high mobility under terrestrial conditions, CO2 injected in an unconfined formation would spread beneath the confining layer to produce a large flat cylindrical‐shaped plume of pure‐phase CO2. In contrast, the less mobile CO2 in a typical deep‐sea reservoir produces a spherical‐shaped plume, resulting in a pure‐phase‐CO2 footprint that is much smaller than the pure‐phase‐CO2 footprint formed in the confined‐terrestrial reservoir.

The morphology of dendrites and the axon determines how a neuron processes and transmits information. Neurite morphology is frequently analyzed by Sholl analysis or by counting the total number of neurites and branch tips. However, the time and resources required to perform such analysis by hand is prohibitive for the processing of large data sets and introduces problems with data auditing and reproducibility. Furthermore, analyses performed by hand or using course‐grained morphometric data extraction tools can obscure subtle differences in data sets because they do not store the data in a form that facilitates the application of multiple analytical tools. To address these shortcomings, we have developed a program (titled “Bonfire”) to facilitate digitization of neurite morphology and subsequent Sholl analysis. Our program builds upon other available open‐source morphological analysis tools by performing Sholl analysis on subregions of the neuritic arbor, enabling the detection of local level changes in dendrite and axon branching behavior. To validate this new tool, we applied Bonfire analysis to images of hippocampal neurons treated with 25 ng/ml brain‐derived neurotrophic factor (BDNF) and untreated control neurons. Consistent with prior findings, conventional Sholl analysis revealed that global exposure to BDNF increases the number of neuritic intersections proximal to the soma. Bonfire analysis additionally uncovers that BDNF treatment affects both root processes and terminal processes with no effect on intermediate neurites. Taken together, our data suggest that global exposure of hippocampal neurons to BDNF results in a reorganization of neuritic segments within their arbors, but not necessarily a change in their number or length. These findings were only made possible by the neurite‐specific Sholl data returned by Bonfire analysis. © 2010 International Society for Advancement of Cytometry

Recombinant human erythropoietins (rHuEPOs) are glycoproteins drugs, produced by the pharmaceutical industry to restore production of red blood cells by stimulating human bone marrow for which this pathology has been diagnosed. It is suspected that these molecules are diverted as doping agents in horseracing to enhance oxygen transport and aerobic power in racehorses. Although indirect double‐blotting or direct liquid chromatography‐mass spectrometry (LC‐MS) methods have been developed to confirm the presence of rHuEPO in a sample, the short detection time (48 h) is still a problem for doping control. In this context, gene profiling investigation through Serial Analysis of Gene Expression (SAGE) has been conducted on seven thoroughbreds treated with Eprex®. This functional genomic method has been performed from total blood cells collected from each animal to assess the mRNA expression consecutive to rHuEPO injections. Sample pooling was chosen as a powerful, cost‐effective, and rapid means of identifying the most common and specific changes in terms of gene expression profile and to eliminate individual variation. Consequently, three SAGE libraries were constructed, before, during, and after Eprex® treatment. More than 71 440 mRNA signatures were observed and subjected to statistical analysis; 49 differentially expressed genes were identified and analyzed by qPCR. From the selected gene list, were defined as potential biomarkers in terms of their low inter‐individual variation and capacity as strong markers of rHuEPO administration up to 60 days after the beginning of the doping period. In this paper, a new strategy is proposed to the horseracing industry to prevent rHuEPO abuse. Copyright © 2010 John Wiley & Sons, Ltd.
Analyses of second‐generation ‘legal highs’ in the UK: Initial findings
Authors: Brandt Simon D. , Sumnall Harry R. , Measham Fiona , Cole Jon
Published: August 2010

In the UK, mephedrone and other so‐called ‘legal high’ derivatives have recently been classified as Class B, Schedule I under the Misuse of Drugs Act 1971. Since then, alternative products have been advertised on a number of websites. In order to obtain an immediate snapshot of the situation, 24 products were purchased online from 18 UK‐based websites over a period of 6 weeks following the ban in April 2010. Qualitative analyses were carried out by gas chromatography ion trap mass spectrometry using electron‐ and chemical ionization modes, nuclear magnetic resonance spectroscopy, and comparison with reference standards. Overall, the purchased products consisted of single cathinones or cathinone mixtures including mephedrone, butylone, 4‐methyl‐N‐ethylcathinone, flephedrone (4‐fluoromethcathinone) and MDPV (3,4‐methylenedioxypyrovalerone), respectively. Benzocaine, caffeine, lidocaine, and procaine were also detected. The emphasis was placed on ‘Energy 1’ (NRG‐1), a product advertised as a legal replacement for mephedrone‐type derivatives usually claiming to contain naphyrone (naphthylpyrovalerone, O‐2482). It was found that 70% of NRG‐1 and NRG‐2 products appeared to contain a mixture of cathinones banned in April 2010 and rebranded as ‘new’ legal highs, rather than legal chemicals such as naphyrone as claimed by the retailers. Only one out of 13 NRG‐1 samples appeared to show analytical data consistent with naphyrone. These findings also suggest that both consumers and online sellers (unlike manufacturers and wholesalers) are, most likely unknowingly, confronted with the risk of criminalization and potential harm.

Ecosystem effects of groundwater depth in Owens Valley, California
Authors: Goedhart C. M. , Pataki D. E.
Published: August 2010

Owens Valley, California, USA, is an important source of water for the city of Los Angeles; however, recent studies have documented losses of grass cover coinciding with decreased watertable depths in many locations. These changes in community composition are assumed to be associated with shallower rooting depths and greater vulnerability to declining watertable depths in grasses compared to neighbouring shrubs. However, the hydraulic properties and water stress resistance of most species in Owens Valley have not been measured. In addition, the relationships between groundwater depth and other aspects of ecosystem function such as nutrient cycling are not well understood. In this study, we measured grass and shrub cover, vulnerability to cavitation, and plant and soil isotopic and chemical composition at 9 sites along a depth to watertable gradient of 0·3–5·7 m in Owens Valley. Contrary to expectations, the grass species was more resistant to water stress‐induced cavitation than either shrub species. However, grass cover declined in sites with deeper watertables while shrub cover remained constant. Water isotopes indicated shallower rooting depths in grasses than in shrubs, although the phreatophytic shrub Ericameria nauseosa had enriched leaf water isotopes at deep groundwater sites, indicating water stress. Sites with lower grass cover contained less soil nitrogen (N) that was also more isotopically enriched, which is indicative of greater ecosystem N losses. These results show that groundwater depth is correlated with a number of ecosystem traits in these Great Basin Desert ecosystems and should be considered when evaluating future changes in groundwater depth.

Evapotranspiration partitioning in semiarid shrubland ecosystems: a two‐site evaluation of soil moisture control on transpiration
Authors: Cavanaugh Michelle L. , Kurc Shirley A. , Scott Russell L.
Published: August 2010

Vegetation of dryland ecosystems is sensitive to precipitation pulses. Future climate scenarios suggest that the frequency and magnitude of precipitation events will change. How much and to what extent will these changes impact the hydrological cycle in creosotebush (Larrea tridentata) shrublands that dominate the three North American hot deserts? In this study, we examine the partitioning of precipitation inputs into bare soil evaporation (E) and transpiration (T) within creosotebush ecosystems at sites characterized by bimodal precipitation regimes: the Santa Rita Experimental Range (SRER) and the Walnut Gulch Experimental Watershed (WGEW). At both sites, during summer 2008, we measured evapotranspiration (ET) using eddy covariance, whole plant T using the heat‐balance sap flow, and soil moisture at several depths. During the dry period preceding the summer monsoon, both ET and soil moisture were very low. With the onset of summer rains, E dominated ET; shrub transpiration did not respond to increases in soil moisture for approximately 3 more weeks. A series of large precipitation events increased moisture at deeper soil layers, and triggered T. Overall, ET was largely correlated to moisture levels in shallow soil layers typical of dryland ecosystems dominated by dry conditions, high evaporative demand, and poor soil infiltration. Under the current precipitation regime, characterized by many small storms and few large storms, soil moisture is low with most precipitation inputs lost as E. However, if climatic changes lead to less frequent but larger precipitation events, dryland communities could experience shifts in the partitioning of ET affecting the hydrologic budget of the ecosystem.

Synthesis of a Chiral Palladacycle and Its Application in Asymmetric Hydrophosphanation Reactions
Authors: Ding Yi , Zhang Yi , Li Yongxin , Pullarkat Sumod A. , Andrews Paul , Leung Pak‐Hing
Published: August 2010

A novel amine ligand, 1‐(2,5‐dimethylphenyl)‐N,N,2,2‐tetramethylpropan‐1‐amine, was synthesized in six steps from commercially available p‐xylene. Direct ortho‐palladation of this amine ligand proceeded readily to form the racemic dimeric complex. The palladacycle structure and ring conformations of its triphenylphosphane derivative were thoroughly investigated by X‐ray structural analysis in the solid state and 2D 1H–1H ROESY NMR spectroscopy in solution. This racemic palladacycle was efficiently resolved through the formation of its (S)‐prolinato derivatives and an efficient separation of the resulting diastereomeric complexes was achieved by slow crystallization with the use of different solvent systems. The structure and absolute configuration of the two optically resolved palladium complexes were determined by X‐ray diffraction. Both the (R,R) and (S,S)‐di‐μ‐chlorido dimeric palladium complexes could be obtained chemoselectively by treating the corresponding prolinato derivatives with 1 M hydrochloric acid. The asymmetric hydrophosphanation reaction between diphenylphosphane and diethyl acetylenedicarboxylate was promoted by this newly synthesized palladacycle and resulted in the formation of a single isomer according to the 31P NMR spectrum. The amine auxiliary could be subsequently removed chemoselectively from the palladium center by treatment with concentrated HCl. An optically pure C2‐symmetrical diphosphane ligand containing two ester functional groups at the two chiral carbon stereogenic centers was prepared by ligand displacement.
The humanity of what we eat: Conceptions of human uniqueness among vegetarians and omnivores
Authors: Bilewicz Michal , Imhoff Roland , Drogosz Marek
Published: August 2010

Studies on dehumanization demonstrated that denying certain human characteristics might serve as a strategy for moral disengagement. Meat consumption—especially in the times of cruel animal farming—is related to the exclusion of animals from the human scope of justice. In the present research, it was hypothesized that the conception of human uniqueness (denying animals certain psychological characteristics) might be a strategy of meat‐eaters' moral disengagement. Three studies compared the extent to which vegetarians and omnivores attribute psychological characteristics to humans versus animals. In Study 1, vegetarian participants ascribed more secondary (uniquely human) emotions to animals than did the omnivores; however, there were no differences in primary (animalistic) emotions. Study 2 showed that omnivores distinguish human characteristics from animalistic ones more sharply than vegetarians do, while both groups do not differ in distinguishing human characteristics from mechanistic ones. Study 3 confirmed the results by showing that omnivores ascribed less secondary emotions to traditionally edible animals than to the non‐edible species, while vegetarians did not differentiate these animals. These results support the claim that the lay conceptions of ‘human uniqueness’ are strategies of moral disengagement. Copyright © 2010 John Wiley & Sons, Ltd.
