Absorption of water/methanol binary system on ion‐exchange resins
Authors: Tesser R. , Di Serio M. , Casale L. , Carotenuto G. , Santacesaria E. 
Published: August 2010

AbstractPolymeric ion‐exchange resins are widely used in important industrial processes for both separation and reaction applications. Due to their particular cross‐linked structure, these materials are subjected to a remarkable swelling phenomena when are contacted with polar solvents like methanol or water. The high liquid volume retained and the selectivity towards the absorption of particular substances can results in a significant alteration of the liquid reactive mixture composition when polymeric resins are used as catalysts. In this situation the bulk liquid phase and the absorbed phase are different in composition and the kinetics could be strongly affected as the chemical reaction occurs mainly on the internal surface of the resin particles. The correct description of the kinetics for such systems requires additional information regarding the phase partitioning of the various components between the liquid and the absorbed phase. In this work, experimental absorption data, concerning the binary system methanol–water partitioned in the presence of Amberlyst 15 and Relite CFS, two sulphonic ion‐exchange resins, typically used as esterification catalysts, are presented. This mixture is of great interest in the esterification reaction of free fatty acids (FFAs) that is nowadays considered a suitable pre‐treatment of cheap feedstock for biodiesel production. The data collected on binary systems water–methanol, at different temperatures, have then been successfully correlated by a multicomponent competitive absorption model that could be useful, in the future, in a wider kinetic study. The same model has also been tested on data taken from the literature.
Complete mapping of glomeruli based on sensory nerve branching pattern in the primary olfactory center of the cockroach Periplaneta americana
Authors: Watanabe Hidehiro , Nishino Hiroshi , Nishikawa Michiko , Mizunami Makoto , Yokohari Fumio 
Published: August 2010

AbstractGlomeruli are structural and functional units in the primary olfactory center in vertebrates and insects. In the cockroach Periplaneta americana, axons of different types of sensory neurons housed in sensilla on antennae form dorsal and ventral antennal nerves and then project to a number of glomeruli. In this study, we identified all antennal lobe (AL) glomeruli based on detailed innervation patterns of sensory tracts in addition to the shape, size, and locations in the cockroach. The number of glomeruli is ∼205, and no sex‐specific difference is observed. Anterograde dye injections into the antennal nerves revealed that axons supplying the AL are divided into 10 sensory tracts (T1–T10). Each of T1–T3 innervates small, oval glomeruli in the anteroventral region of the AL, with sensory afferents invading each glomerulus from multiple directions, whereas each of T4–T10 innervates large glomeruli with various shapes in the posterodorsal region, with a bundle of sensory afferents invading each glomerulus from one direction. The topographic branching patterns of all these tracts are conserved among individuals. Sensory afferents in a sub‐tract of T10 had axon terminals in the dorsal margin of the AL and the protocerebrum, where they form numerous small glomerular structures. Sensory nerve branching pattern should reflect developmental processes to determine spatial arrangement of glomeruli, and thus the complete map of glomeruli based on sensory nerve branching pattern should provide a basis for studying the functional significance of spatial arrangement of glomeruli and its developmental basis.

Evaluation of the Chemical Reactions from Two Electrogenerated Species in Picoliter Volumes by Scanning Electrochemical Microscopy
Authors: Wang Qian , Rodríguez‐López Joaquín , Bard Allen J. 
Published: August 2010

AbstractThe volume created by the positioning of two scanning electrochemical microscope (SECM) probes (tip and substrate) at a micrometric distance defines a “picoliter beaker” where homogeneous electron‐transfer reactions are studied. The SECM is used to concurrently electrogenerate in situ two reactive species and to evaluate the possibility of detecting their reactivity. Two reaction cases are studied: the first, called the “reversible case”, occurs when the electrochemically generated species at the substrate electrode can also react at the tip to yield the same product as the reaction in the gap. The second case, named the “irreversible case”, occurs when the electrochemically generated species at the substrate are not able to react at the tip. Digital simulations are performed and compared to experimental studies. These show that an unusual compensation between collection and feedback effects render the analysis inapplicable in the “reversible case”. The “irreversible case” is shown experimentally.
Cued platform training reveals early development of directional responding among preweanling rats in the Morris water task

Published: August 2010

AbstractPrevious studies on the ontogeny of spatial learning report that rats younger than 19–21 days of age are incapable of learning the location of a platform relative to distal cues in the Morris water task. Here, we manipulated the spatial relationship of a cued platform to the pool and the distal visual room cues to investigate whether distal cues can control navigation among 16‐ to 24‐day‐old rats. Rats were trained to navigate to a cued platform in a rich distal cue environment. During critical test trials, the pool was shifted to a different, overlapping position and the cued platform was placed either in the same absolute location in the room or the same relative location in the pool as during training. Rats aged 17 days and older exhibited a disruption in performance when the cued platform was in the absolute location but not the relative location, indicating that rats had learned the direction of the cued platform within the distal cue environment. These observations indicate that (1) information acquired from distal room cues influences navigation as early as 17 days of age, (2) this distal cue information is preferentially used to guide navigation in a particular direction rather than to a precise place in the room, and (3) the directional nature of the influence of distal cues on navigation is invariant across development. © 2010 Wiley Periodicals, Inc.

The response of sap flow in desert shrubs to environmental variables in an arid region of China
Authors: Liu Bing , Zhao Wenzhi , Jin Bowen 
Published: August 2010

AbstractA case study was conducted in a desert–oasis ecotone in the middle of China's Heihe River basin to reveal the response of sap velocity to environmental variables. We measured sap flow in the branches and stems of desert shrubs (Nitraria sphaerocarpa and Elaeagnus angustifolia) using sap‐flow gauges, and simultaneously measured environmental variables at the study site. The relationships between sap velocity and the environmental variables were analysed using redundancy analysis. The diurnal variation in sap velocity was best described by a bimodal curve, except for the branches of N. sphaerocarpa, which followed a unimodal curve. Sap flow began about 1 h earlier in the branches than in the stems. The dynamic variations in sap velocity were remarkably similar for the two species at a given position (stem vs branch) but differed between the two positions for each species. Redundancy analysis and Kendall's tau analysis indicated that precipitation had the greatest influence on sap velocity in the stem, whereas precipitation duration significantly affected sap velocity in the branches of the desert shrubs (R2 = 0·85 and 0·73, respectively). The variation in sap velocity could be described by a multiple linear regression against the meteorological variables, and the simulated value was significantly linearly correlated with the measured value (0·861 ≤ R2 ≤ 0·938, P < 0·0001).

Published: August 2010

AbstractThe reaction of 2H‐benzotriazole (1) with dichloroacetic acid leads to the symmetric bis(2H‐benzotriazol‐2‐yl)methane (2c) in 40 % yield. Deprotonation of 2c at the bridging methylene group and subsequent carboxylation with CO2 yielded the new tripodal N,N,O ligand bis(2H‐benzotriazol‐2‐yl)acetic acid Hbbta (3). The sterically less demanding sodium 3,3‐bis(1H‐1,2,4‐triazol‐1‐yl)propionate Na[btp] (5) was obtained by saponification of methyl 3,3‐bis(1H‐1,2,4‐triazol‐1‐yl)propionate (4). The heteroscorpionate ligand 3 was treated with [MnBr(CO)5] and [RuCl2(PPh3)3] to form the manganese tricarbonyl complex [Mn(bbta)(CO)3] (6) and the air stable ruthenium complex [Ru(bbta)Cl(PPh3)2] (7). DFT calculations and the IR spectra of the carbonyl complex 6 reveal ligand 3 to be a less electron‐donating ligand compared to the bis(1H‐pyrazol‐1‐yl)acetic acid Hbpza. In case of the 1H‐1,2,4‐triazole‐based ligand 5 formation of coordination polymers were observed as proven by the synthesis of [Zn(btp)2]∞ (8) and [Mn(btp)2]∞ (9). Polymer 8 crystallises in linear chains of zinc atoms bridged by two molecules of ligand 5 each. These polymer chains show an interesting π‐stacking interaction between uncoordinated triazole residues of the ligands. Deposition of the coordination polymer on highly ordered pyrolytic graphite (HOPG) was successful and was analysed by scanning tunnelling microscopy (STM). Reaction of Na[btp] (5) with MnSO4·H2O resulted in a metal organic framework (MOF) [Mn(btp)2]∞ (9).
Social dominance‐based threat reactions to immigrants in need of assistance
Authors: Costello Kimberly , Hodson Gordon 
Published: August 2010

AbstractThe present investigation examined how individuals higher in social dominance orientation (SDO) react to experimentally induced intergroup threat in terms of support for helping immigrants. Participants read editorials describing an incoming immigrant outgroup posing realistic threats (to tangible resources and well‐being), symbolic threats (to values and traditions) or no threats. Participants higher in SDO exhibited greater resistance to helping immigrants upon exposure to realistic, symbolic, (Experiments 1 and 2), or combined realistic–symbolic (Experiment 2) intergroup threats, but not when the same immigrants posed no threats. In Experiment 2, SDO exerted indirect effects on modern prejudice through both heightened infra‐humanization and intergroup anxiety, with modern prejudice itself predicting greater resistance and indifference to helping immigrants. Moderated mediation analyses revealed strongest SDO‐infra‐humanization relations under conditions of symbolic threat. Implications for prejudice‐reduction interventions are considered.

Specific attentional impairments and complex visual hallucinations in eye disease
Authors: Graham G , Dean J , Mosimann UP , Colbourn C , Dudley R , Clarke M , Collerton D 
Published: August 2010

AbstractObjectiveTo test the prediction by the Perception and Attention Deficit (PAD) model of complex visual hallucinations that cognitive impairment, specifically in visual attention, is a key risk factor for complex hallucinations in eye disease.MethodsTwo studies of elderly patients with acquired eye disease investigated the relationship between complex visual hallucinations (CVH) and impairments in general cognition and verbal attention (Study 1) and between CVH, selective visual attention and visual object perception (Study 2). The North East Visual Hallucinations Inventory was used to classify CVH.ResultsIn Study 1, there was no relationship between CVH (n = 10/39) and performance on cognitive screening or verbal attention tasks. In Study 2, participants with CVH (n = 11/31) showed poorer performance on a modified Stroop task (p < 0.05), a novel imagery‐based attentional task (p < 0.05) and picture (p < 0.05) but not silhouette naming (p = 0.13) tasks. Performance on these tasks correctly classified 83% of the participants as hallucinators or non‐hallucinators.ConclusionsThe results suggest that, consistent with the PAD model, complex visual hallucinations in people with acquired eye disease are associated with visual attention impairment.
