Kinetics of the dissolution of copper metal in some chelating systems under oxygen pressure
Creators: name: Milants, Henri Yves Jean
Publisher: name: University of British Columbia
Year: 2012

description: An investigation was conducted on the dissolution of copper metal in aqueous solutions of ethylenediamine, glycine, α-alanine and β-alanine, under oxygen pressure. The kinetics of these reactions were investigated over a wide concentration range of the corresponding ionized species. The rate of dissolution of copper, in all solutions, has been found to be independent of the initial copper concentration, the volume of the solution and the area of the copper sample. No intermediate products, i.e., cuprous ions, were observed. Two regions were observed, having different dependence on oxygen pressure. In one, the rate depends on the first power of the oxygen pressure, and is independent of the concentration of the chelating agent. In the other region, the reaction is first order in chelating agent and independent of oxygen pressure. The rate of the reaction in this second region appears to be chemically controlled at the copper surface. The neutral and charged species of the chelating agent were found to have independent rates. These two dissolution reactions were found to be first order with respect to the concentration of the respective complexing species. The mechanism proposed by Halpern previously for the ammonia system was found to be applicable to the systems studied in the present work. The rate constants for each chelating agent have been computed and appear to be related to the stability constants. No steric effect was observed.

description: The extraordinary magnetic Ap star HD75049 has been studied with data obtained with the ESO VLT and 2.2-m telescopes. Direct measurements reveal that the magnetic field modulus at maximum reaches 30kG. The star shows photometric, spectral and magnetic variability with a rotation period of 4.049d. Variations of the mean longitudinal magnetic field can be described to first order by a centred dipole model with an inclination i = 25 degrees, an obliquity beta = 60 degrees, and a polar field B_p = 42kG. The combination of the longitudinal and surface magnetic field measurements imply a radius of R = 1.7 R sun, suggesting the star is close to the zero-age main sequence. HD75049 displays moderate overabundances of Si, Ti, Cr, Fe and large overabundances of rare earth elements. This star has the second strongest magnetic field of any main sequence star after Babcock's star, HD215441, which it rivals.
Current measurements in Knight Inlet, 1956.
Creators: name: Rodgers, George Keith
Publisher: name: University of British Columbia
Year: 2012

description: Current measurements were made in Knight Inlet during the period, July 4th to 11th, 1956. A current drag, designed at the Chesapeake Bay Institute, was employed for current measurements in the upper 20 meters of the water column. An Ekman current meter was used at depths below 20 meters. Corrections for ship motion were applied to the Ekman current meter readings. This investigation consists of : (1) a general analysis of the techniques used in the collection and treatment of the data, (2) a description of the currents obtained from the above treatment of the data. Currents at every depth of measurement showed oscillating or fluctuating components superimposed on a net current. Tidal forces appear to act at all depths. The direct effect of wind stress on currents is apparent to depths of at least 10 meters. Indirect wind effects are indicated at greater depths.

description: We give a review of the existence of Taub-NUT/bolt solutions in Einstein Gauss-Bonnet gravity with the parameter $α$ in six dimensions. Although the spacetime with base space $S^{2}\times S^{2}$ has curvature singularity at $r=N$, which does not admit NUT solutions, we may proceed with the same computations as in the $\mathbb{CP}^{2}$ case. The investigation of thermodynamics of NUT/Bolt solutions in six dimensions is carried out. We compute the finite action, mass, entropy, and temperature of the black hole. Then the validity of the first law of thermodynamics is demonstrated. It is shown that in NUT solutions all thermodynamic quantities for both base spaces are related to each other by substituting $α^{\mathbb{CP}^{k}}=[(k+1)/k]α^{S^{2} \times S^{2}\times >...S_{k}^{2}}$. So no further information is given by investigating NUT solution in the $S^{2}\times S^{2}$ case. This relation is not true for bolt solutions. A generalization of the thermodynamics of black holes to arbitrary even dimensions is made using a new method based on the Gibbs-Duhem relation and Gibbs free energy for NUT solutions. According to this method, the finite action in Einstein Gauss-Bonnet is obtained by considering the generalized finite action in Einstein gravity with an additional term as a function of $α$. Stability analysis is done by investigating the heat capacity and entropy in the allowed range of $α$, $Λ$ and $N$. For NUT solutions in $d$ dimensions, there exist a stable phase at a narrow range of $α$. In six-dimensional Bolt solutions, metric is completely stable for $\mathcal{B}=S^{2}\times S^{2}$, and is completely unstable for $\mathcal{B}=\mathbb{CP}^{2}$ case.

description: Despite the research tradition in analyzing public communication, local public spheres have been rather neglected by communication science, although they are crucial for social cohesion and democracy. Existing empirical studies about local public spheres are mostly case studies which implicitly assume that cities are alike. Based on a participatory-liberal understanding of democracy, we develop a theoretical framework, from which we derive a monitor covering structural, social, and spatial aspects of local communication to empirically compare local public spheres along four dimensions: (1) information, (2) participation, (3) inclusion, and (4) diversity. In a pilot study, we then apply our monitor to four German cities that are comparable in size and regional function (‘regiopolises’). The monitoring framework is built on local statistical data, some of which was provided by the cities, while some came from our own research. We show that the social structures and the normative assessment of the quality of local public spheres can vary among similar cities and between the four dimensions. We hope the innovative monitor prototype enables scholars and local actors to compare local public spheres across spaces, places, and time, and to investigate the impact of social change and digitalization on local public spheres.

Το ιπποφαές ή Hippophaë rhamnoides L. χρησιμοποιηθεί στην παραδοσιακή ιατρική διαφόρων χωρών, όπως η Κίνα, η Ινδία, το Πακιστάν για την αντιμετώπιση διαφόρων ασθενειών όπως για δερματοπάθειες, για την επούλωση τραυμάτων και εγκαυμάτων, για την αντιμετώπιση οιδημάτων, φλεγμονών και βακτηριακών λοιμώξεων, ως καθαρτικό, ακόμη και για αντιμετώπιση πεπτικών διαταραχών. Επίσης, οι καρποί του ιπποφαούς έχουν χρησιμοποιηθεί για την παρασκευή ροφημάτων, γλυκισμάτων και καλλυντικών. Έχει μελετηθεί από την επιστημονική κοινότητα διεξοδικά η χημική σύνθεση διαφόρων φυτικών τμημάτων του ιπποφαούς: της σάρκας, της φλούδας και των σπόρων του καρπού, των φύλλων, αλλά και των βλαστών, του φλοιού και της ρίζας. Βρέθηκε ότι κυρίως οι καρποί και τα φύλλα έχουν μία πλούσια σύνθεση σε βιοδραστικά συστατικά σε υψηλές συγκεντρώσεις: φλαβονοειδή, φαινολικά οξέα, βιταμίνες, τοκοφερόλες, καροτενοειδή, λιπαρά οξέα, αιθέρια έλαια, αμινοξέα, ιχνοστοιχεία. Οι ουσίες αυτές έχουν ένα ευρύ δυνητικό φάσμα θετικών επιδράσεων στον ανθρώπινο οργανισμό. Ένας μεγάλος αριθμός επιστημονικών ερευνών έχουν διεξαχθεί με σκοπό να αξιολογήσουν, να εντοπίσουν και να προσδιορίσουν την ευεργετική επίδραση του ιπποφαούς στην ανθρώπινη υγεία. Τα αποτελέσματα αυτών των μελετών είναι πολύ αισιόδοξα και δείχνουν ότι το ιπποφαές μπορεί να έχει αντιμικροβιακή δράση έναντι βακτηρίων και μυκήτων, αντιοξειδωτική, ηπατοπροστατευτική και ακτινοπροστατευτική δράση, να επιδρά θετικά στον περιορισμό της υπερβολική έκκρισης σμήγματος, στη θεραπεία πληγών και εγκαυμάτων, στην αντιμετώπιση των συμπτωμάτων της ψωρίασης και της ατοπικής δερματίτιδας, και, επιπλέον, μπορεί να λειτουργεί καρδιοπροστατευτικά, ακόμη και να βοηθάει στην πρόληψη και τη θεραπεία του καρκίνου.

description: Dentin collagen degradation represents an important limit to the stability of the resin-dentin interface in conservative dentistry. In vitro application of 1-ethyl-3-(3- dimethylaminopropyl)-carbodiimide hydrochloride (EDC), an imide-based zerolength cross-linking agent, showed [1] the capability to inactivate the endogenous dentin matrix metalloproteinases and to increase the mechanical properties of the organic dentin extracellular matrix. In the present study, a correlative high resolution SEM (FEISEM) with an Energy Dispersive Spectroscopy (EDS) analysis was performed to characterize the fine structure and the chemical modifications of EDCstabilized human dentin, after compressive mechanical stress (Chewing Simulation - CS). Demineralized human dentin disks were assigned to four groups: (1) artificial saliva at 37°C for 30 days; (2) pre-treatment with 0.5M EDC for 60 s, then as in Group 1; (3) CS challenge for 30 days; (4) 0.5M EDC as in Group 2 and CS challenge as in Group 3. The FEISEM analysis revealed that the EDC-pretreatment made the collagen fibrillar network more compact, in comparison to controls and this effect was particularly evident on the surface of not stressed samples. Along with the increased compactness of the collagen complex, the EDS analysis showed a significant semi-quantitative increase of sulfur. The presence of chlorine in EDC treated samples was also detectable. The increase of sulfur, not present in EDC composition, suggests a possible implication of sulfate glycosaminoglycans containing proteoglycans during the extracellular matrix stabilization, as also suggested by the concurrent increase of the amorphous matrix. The presence of chlorine in EDC treated samples induces to conclude that the activity of the cross-linking agent is stable even after the experimental time intervals.

description: Ένας από τους βασικούς στόχους των αναλογιστών είναι, συγκρίνοντας κάποιες τυχαίες καταστάσεις, να επιλέξουν αυτή με το λιγότερο ρίσκο. Οι συγκρίσεις αυτές βασίζονται κυρίως στη σύγκριση των μέσων τιμών ή και διακυμάνσεων τους, που όμως σε ορισμένες περιπτώσεις δεν είναι πολύ βοηθητικές. Έτσι, αναπτύχθηκε η θεωρία των στοχαστικών διατάξεων, η οποία εξασφαλίζει μια πιο λεπτομερή και ακριβή σύγκριση. Δύο από τα είδη στοχαστικών διατάξεων με ευρεία χρήση στην Αναλογιστική Επιστήμη τα τελευταία χρόνια, είναι η διάταξη της Ροπογεννήτριας και του Μετασχηματισμού Laplace. Στην πρώτη περίπτωση είναι απαραίτητη η ύπαρξη της ροπογεννήτριας για τις μεταβλητές που εξετάζουμε, ενώ στη δεύτερη περίπτωση όχι. Σκοπός της παρούσας εργασίας είναι να παρουσιαστούν και να μελετηθούν οι ιδιότητες των δύο αυτών διατάξεων, καθώς και να εξεταστεί η σχέση τους με άλλα είδη στοχαστικών διατάξεων. Επίσης, στόχος είναι να γίνουν εφαρμογές σε ορισμένες κατανομές όπου θα πραγματοποιηθούν συγκρίσεις σε Μετασχηματισμούς Laplace και Ροπογεννήτριες και κατ’ επέκταση στη θεωρία συλλογικού κινδύνου.

description: Vav1, normally restricted to hematopoietic cells, results ectopically expressed in solid tumors, including breast cancer (Sebban et al., 2013) in which, contrarily to other neoplasias, seems to be higher in tumors from patients who remained diseasefree than in patients who developed recurrence (Lane et al., 2008). The significance of Vav1 expression in breast tumors was evaluated by immunohistochemical analysis on TMAs containing invasive breast tumors from patients without lymph node involvement. Our findings indicate that Vav1 is expressed in almost all investigated cancers and shows a peculiar localization inside the nucleus of tumor cells. High amounts of nuclear Vav1 positively correlates with low incidence of relapse, regardless phenotype and molecular subtype of the neoplasia. Experiments performed with breast tumor-derived cells showing different morphology, immunoprofile and invasive properties indicated that Vav1 negatively modulates their invasiveness in vitro and their metastatic efficiency in vivo, possibly by affecting the expression of genes involved in invasion and/or metastasis of breast cancer. Since the high heterogeneity of breast tumors makes difficult to predict the evolution of early neoplasias, the evaluation of nuclear Vav1 levels may help in profiling and management of early breast cancer patients. In addition, Vav1 may serve as a target for new therapies designed to prevent breast cancer progression.

description: We report on the study of terahertz radiation-induced MIRO-like oscillations of magnetoresistivity in GaAs heterostructures. Our experiments provide an answer on two most intriguing questions-effect of radiation helicity and the role of the edges-yielding crucial information for an understanding of the MIRO (microwave-induced resistance oscillations) origin. Moreover, we demonstrate that the range of materials exhibiting radiation-induced magneto-oscillations can be largely extended by using high-frequency radiation.
Space-charge-limited currents in germanium

description: A study has been made of space-charge-limited hole flow in germanium by investigating the current-voltage-temperature characteristics of selected p-n-p transistors used as diodes with the base open-circuited. These transistors were selected so as to minimize the effect of avalanche multiplication. These diodes pass hole current through the base after a voltage designated as the punchthrough voltage has been applied to deplete the n type base of electrons. The resulting space-charge-limited current above punchthrough has been closely studied and also its temperature dependence. To explain the form of these characteristics, published data have been used for the relationship between electric field and carrier drift velocity for holes in germanium in order to consider the hole flow through the high field region of the base. It was further found necessary to consider the variation of effective emitting area as the applied voltage is increased past punchthrough. For high applied voltages and hence high applied fields in the base, a constant differential resistance is obtained of magnitude about equal to that expected theoretically for a constant drift velocity of holes in the base. The temperature dependence of this current can be satisfactorily explained by the temperature variation of the base-generated current and of the punchthrough voltage itself. A satisfactory model of the latter variation has been made by considering the temperature variation of the potential barrier at the emitter junction. If the observed characteristics are corrected for these variations, there is found to be negligible variation of the space-charge-limited hole -flow. Capacitance measurements were made on both junctions for these diodes. From these measurements the assumption of a step junction and of uniform impurity distribution in the base were justified. No abrupt change of capacitance was observed as the voltage was increased through the punchthrough voltage contrary to the findings of Barker. The original theories of Shockley-Prim-Dacey were extended to include the effects of (i) mobility variation over a wide range of-fields (ii) non-planar geometry and (iii) the potential distribution near the emitter junction.

Αρχικά, παρουσιάστηκαν τα κυριότερα είδη ζυμαρικών και οσπρίων, καθώς και η σύσταση και τα διατροφικά τους χαρακτηριστικά. Εμφανίστηκε πλούσια περιεκτικότητα για τα ζυμαρικά σε υδατάνθρακες και σε πρωτεΐνες, ενώ για τα όσπρια σε φυτικές ίνες για τα όσπρια. Έτσι, έγινε αντιληπτός ο σκοπός του εμπλουτισμού των ζυμαρικών με άλευρα οσπρίων και παρουσιάστηκαν διάφορες προσπάθειες εμπλουτισμού. Στη συνέχεια, προσδιορίστηκε η επίδραση του εμπλουτισμού στα ποιοτικά χαρακτηριστικά των προϊόντων. Αρχικά, στη ζύμη η πλειοψηφία των ερευνών έδειξε αύξηση της απορρόφησης νερού και μείωση του χρόνου ανάπτυξης της ζύμης. Κατά τη διάρκεια της ξήρανσης, επηρεάστηκαν η επιφάνεια κι η μικροδομή των ζυμαρικών, ενώ κατά την υγροθερμική επεξεργασία των τελικών προϊόντων αυξάνονται το βάρος μαγειρεμένου προϊόντος, η απορρόφηση νερού, οι απώλειες μάζας, ενώ ο βέλτιστος χρόνος μαγειρέματος είτε αυξάνεται είτε μειώνεται με βάση τη βιβλιογραφία. Η οργανοληπτική αξιολόγηση κατέδειξε ότι σε χαμηλά ποσοστά υποκατάστασης με άλευρα οσπρίων εμφανίζονται θετικά αποτελέσματα, αλλά σε υψηλά ποσοστά τα αποτελέσματα ήταν αρνητικά.

description: The styloid process of the temporal bone has a variable length as demonstrated in studies conducted with different technique: three-dimensional computed tomography or dental panoramic three-dimensional scanning. Data on the osteometric values of the styloid process is scanty with significant length differences existing between the studies attributed to different races or ethnicities.The abnormal length can be in some cases accompanied by a set of symptoms, characterized by neck pain, dysphagia, headache, sore throat, ear pain, mandible dysfunction clinically framed in Eagle’s syndrome. We present an osteometric study on the length of the styloid process of a collection of dried skulls belonging to the museum of Anatomy “Leonetto Comparini “ at the University of Siena. All skulls came from the local psychiatric hospital. For measurement we employed a digital caliper . The data were analyzed through a free statistical software (Salstat 2) . Average and standard deviation (sd), were calculated. Univariate analysis of the length of the styloid process gave the following results: average: 27 mm ; sd : 7 mm ; normal range : average +/- 2 sd : 41-13 mm. The longest styloid process was 52 mm and the shortest had a length of 0.5 mm .In one case we discovered a skull with stylohyoid calcified ligament on one side . The styloid process was long 50 mm on the right and 70 mm on the left where is the tip calcified .An abnormal long styloid process>41 mm is present in 6% of items in our biometric study . The abnormal variations in length are put in relation to the possible anatomical change of the muscular and ligamentous structures of the styloid process by drawings of a case with a marked elongation of the styloid process.The shortening of the stylomandibular ligament that we suppose considering the distance from the angle of mandible of the tip and the possible change in direction could cause difficult in the protrusion of mandible and in mastication. The shortening of stylohyoid ligaments and muscles, could cause difficult in movement of os hyoid and in raising or lowering of larynge during swallowing.

description: Zero temperature properties of a dilute weakly interacting $d$-dimensional Bose gas in a random potential are studied. We calculate geometrical and energetic characteristics of the localized state of a gas confined in a large box or in a harmonic trap. Different regimes of the localized state are found depending on the ratio of two characteristic length scales of the disorder, the Larkin length and the disorder correlation length. Repulsing bosons confined in a large box with average density $n$ well below a critical value $n_c$ are trapped in deep potential wells of extension much smaller than distance between them. Tunneling between these wells is exponentially small. The ground state of such a gas is a random singlet with no long-range phase correlation For $n>n_c$ repulsion between particles overcomes the disorder and the gas transits from the localized to a coherent superfluid state. The critical density $n_c$ is calculated in terms of the disorder parameters and the interaction strength. For atoms in traps four different regimes are found, only one of it is superfluid. The theory is extended to lower (1 and 2) dimensions. Its quantitative predictions can be checked in experiments with ultracold atomic gases and other Bose-systems.

description: Public spheres research has traditionally sidestepped questions of space by focusing on a priori delineated political territories, most prominently national public spheres. While this approach has always lacked nuance, it has become acutely insufficient nowadays, as digital communication technologies easily enable a host of heterogeneous actors to draw public attention to spaces and places at any scale, and communicatively connect places anywhere in the world. This conceptual article argues that communication scholars need to reconsider the spaces embedded in the content of public discourses. Drawing on the notion of issue publics, it understands the public definition of issues as inextricably linked to the places that are communicatively associated with them, causing issue spaces to emerge. The issue space is constructed through place-naming whenever public actors reference places in the context of issues. The article develops issue spatiality as an analytical framework to understand the role of place and space in public discourse. It discusses how issue spatiality enables a better understanding of the increasingly complex scales of public communication, and outlines several dimensions of issue spatiality. Drawing on communication infrastructure literature, it proposes socio-spatial inequalities of communicative resources as important predictors of issue spatiality, along with the habits of professional communicators, and local problem properties. Gazetteers and mapping techniques are introduced as methodological interventions required for the empirical use of issue spatiality.

description: Some models providing shell-shaped static solutions with compact support (compactons) in 3+1 and 4+1 dimensions are introduced, and the corresponding exact solutions are calculated analytically. These solutions turn out to be topological solitons, and may be classified as maps $S^3 \to S^3$ and suspended Hopf maps, respectively. The Lagrangian of these models is given by a scalar field with a non-standard kinetic term (K field) coupled to a pure Skyrme term restricted to $S^2$, rised to the appropriate power to avoid the Derrick scaling argument. Further, the existence of infinitely many exact shell solitons is explained using the generalized integrability approach. Finally, similar models allowing for non-topological compactons of the ball type in 3+1 dimensions are briefly discussed.

description: Endothelial progenitor cells (EPCs) are mobilized into circulation to replace damaged endothelial and recapitulate the vascular network of injured tissues (Moccia F et al., 2014). Intracellular Ca(2+) signals are key to EPC activation, but it is yet to be elucidated whether they are endowed with the same blend of Ca(2+) –permeable channels expressed by mature endothelial cells. For instance, endothelial colony forming cells (ECFCs), the only EPC subset truly committed to acquire a mature endothelial phenotype, lack canonical transient receptor potential channels 3, 5 and 6 (TRPC3, 5 and 6), which are widely distributed in vascular endothelium; on the other hand, they express a functional store-operated Ca(2+) entry (SOCE). The present study was undertaken to assess whether human circulating EPCs possess TRP vanilloid channel 4 (TRPV4), which plays a master signalling role in mature endothelium, by controlling both vascular remodelling and arterial pressure. W e found that EPCs express both TRPV4 mRNA and protein indicating that human circulating EPCs possess a functional TRPV4 protein before their engraftment into nascent vessels (Dragoni et al., 2014).

This effect clearly depends on the update rule: it diminishes with stochastic imitative rules whereas it increases with unconditional imitation. To study the transition between both regimes, we propose a new evolutionary rule, which stochastically combines unconditional imitation with another imitative rule. We find that, surprinsingly, in many social dilemmas this rule yields higher cooperative levels than any of the two original ones. This nontrivial effect occurs because the basic rules induce a separation of timescales in the microscopic processes at cluster interfaces. The result is robust in the space of 2x2 symmetric games, on regular lattices and on scale-free networks.
