Modeling the cyanide heap leaching of cupriferous gold ores
Creators: name: Coderre, Francois
Publisher: name: University of British Columbia
Year: 2009

description: A mathematical model of cyanidation heap leaching of cupriferous gold ores which includes the speciation of all cyanide, cyanate, thiocyanate, hydroxide and sulfate complexes, and their corresponding copper and gold precipitates, was developed to facilitate the treatment of these complex ores. The concepts of back mixing and solution retention are represented by two fundamentally different fluid elements: i) the bulk solution flowing through the heap, and ii) a stagnant solution reservoir adjoining and enclosed by the ore particles. Four 1.5 m tall column tests simulating actual heap leaching behavior under different nominal influent cyanide concentrations were operated for a period of up to seven months, along with semi-batch coarse ore and batch fine ore leaching tests. The resulting experimental data were used for the calibration and validation of the model. It was found that, in the presence of significant copper sulfate mineralization, the pH of the solution would naturally buffer to approximately 4.6. Further pH decrease to 3.5 is provoked by the oxidation of cyanide to cyanate by cupric ions. At such low pH levels, it is thought that cuprous and aurous cyanide salts tend to precipitate out of solution both within and around porous ore particles. As a result, neither dissolved gold nor dissolved copper from secondary copper sulfides appear in the column effluent for a significant period of time, depending on the influent cyanide concentration and the height of the column. Once dissolved again, gold appears in the column effluent, whereas its leaching kinetics are a strong function of leaching kinetics of secondary copper sulfide minerals such as covellite and chalcocite. Furthermore, the combined effect of covellite leaching and copper sulfate discharge is synergistic in that both promote the precipitation of copper hydroxide. This leads to the dispersal of a Cu(OH)₂(s) reserve throughout the column which has the effect of increasing the long term cyanide consumption. This, in turn, affects the leaching of secondary copper sulfides, and hence, of gold.

description: We consider an effective theory (ET) approach to flavour-violating processes beyond the Standard Model (SM), where the breaking of flavour symmetry is described by spurion fields whose low-energy vacuum expectation values are identified with the SM Yukawa couplings. Insisting on canonical mass dimensions for the spurion fields, the large top-quark Yukawa coupling also implies a large expectation value for the associated spurion, which breaks part of the flavour symmetry already at the UV scale Lambda of the ET. Below that scale, flavour symmetry in the ET is represented in a non-linear way by introducing Goldstone modes for the partly broken flavour symmetry and spurion fields transforming under the residual symmetry. As a result, the dominance of certain flavour structures in rare quark decays can be understood in terms of the 1/Lambda expansion in the ET. We also discuss the generalization to 2-Higgs-doublet models with large tan(beta).

description: We present a method for simulating the dynamics of a mixture of gas and multiple species of large Stokes number dust grains, typical of evolved protoplanetary discs and debris discs. The method improves upon earlier methods, in which only a single grain size could be represented, by capturing the differential backreaction of multiple dust species on the gas. This effect is greater for large dust-to-gas ratios that may be expected in the later stages of the protoplanetary disc life. We benchmark the method against analytic solutions for linear waves, drag and shocks in dust-gas mixtures, and radial drift in a protoplanetary disc showing that the method is robust and accurate.

Evaluation of Diamond Grade Reflective Sheeting

Publisher: name: Kentucky Transportation Center, University of Kentucky

Subjects: subject: Transportation Engineering

description: The objective of this project was to monitor the performance of the diamond grade sheeting when used on both typical traffic signs and construction signs. The durability, appearance, and reflectivity of the signs were monitored. Diamond grade sheetings used on typical traffic signs were evaluated over a two-year period with construction signs evaluated over an 18-month period.  Diamond grade sheeting was found to provide increased reflectivity compared to high intensity sheeting with no problems noted related to durability or appearance. However, the cost of the diamond grade sheeting would limit its use to situations where brighter, wider-angle reflective sheeting is warranted and the increased cost can be justified. Locations where the use of diamond grade sheeting should be considered because of its higher reftectivity include the following:      signs in areas with high levels of ambient lighting,     work zones (especially in urban locations) where the roadway environment is visually cluttered, and     high accident locations involving a nighttime accident problem.  A location where use of diamond grade sheeting could be considered because of the increased viewing angle would be for overhead signs in urban areas. These increased angles would only be a factor when the driver is attempting to view the sign at a locations close to the sign which could be the situation at urban intersections.
The all-particle spectrum of primary cosmic rays in the wide energy range from 10^14 eV to 10^17 eV observed with the Tibet-III air-shower array

description: We present an updated all-particle energy spectrum of primary cosmic rays in a wide range from 10^14 eV to 10^17 eV using 5.5 times 10^7 events collected in the period from 2000 November through 2004 October by the Tibet-III air-shower array located at 4300 m above sea level (atmospheric depth of 606 g/cm^2). The size spectrum exhibits a sharp knee at a corresponding primary energy around 4 PeV. This work uses increased statistics and new simulation calculations for the analysis. We performed extensive Monte Carlo calculations and discuss the model dependences involved in the final result assuming interaction models of QGSJET01c and SIBYLL2.1 and primary composition models of heavy dominant (HD) and proton dominant (PD) ones. Pure proton and pure iron primary models are also examined as extreme cases. The detector simulation was also made to improve the accuracy of determining the size of the air showers and the energy of the primary particle. We confirmed that the all-particle energy spectra obtained under various plausible model parameters are not significantly different from each other as expected from the characteristics of the experiment at the high altitude, where the air showers of the primary energy around the knee reaches near maximum development and their features are dominated by electromagnetic components leading to the weak dependence on the interaction model or the primary mass. This is the highest-statistical and the best systematics-controlled measurement covering the widest energy range around the knee energy region.

description: Three-dimensional Weyl semimetals have pairs of topologically protected Weyl nodes, whose projections onto the surface Brillouin zone are the end points of zero energy surface states called Fermi arcs. At the endpoints of the Fermi arcs, surface states extend into and are hybridized with the bulk. Here, we consider a two-dimensional junction of two identical Weyl semimetals whose surfaces are twisted with respect to each other and tunnel-coupled. Confining ourselves to commensurate angles (such that a larger unit cell preserves a reduced translation symmetry at the interface) enables us to analyze arbitrary strengths of the tunnel-coupling. We study the evolution of the Fermi arcs at the interface, in detail, as a function of the twisting angle and the strength of the tunnel-coupling. We show unambiguously that in certain parameter regimes, all surface states decay exponentially into the bulk, and the Fermi arcs become Fermi loops without endpoints. We study the evolution of the `Fermi surfaces' of these surface states as the tunnel-coupling strengths vary. We show that changes in the connectivity of the Fermi arcs/loops have interesting signatures in the optical conductivity in the presence of a magnetic field perpendicular to the surface.

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1993
Subjects: subject: Transportation Engineering

description: A mandatory safety belt ordinance was enacted in Fayette County with an effective date of July 1, 1990. One objective of this study was to conduct usage surveys after the ordinance had been in effect for approximately three years. This would allow comparisons to be made of safety belt usage before and immediately after the effective date of the ordinance to that found a substantial time period after enactment of the ordinance. A second objective of the study was to compere accident data before and after the ordinance became effective. The would allow an analysis of the effect the ordinance had on accident severity. The third objective involved an analysis of citation data in order to determine the level of enforcement of the ordinance.  The usage rate for drivers was approximately 37 percent before enactment of the ordinance. After the ordinance became effective and enforcement began on July 1, 1990, the usage rate for drivers increased to approximately 76 percent. However, after approximately three years, the usage rate for drivers has dropped to about 59 percent.  Citation data were summarized for the three·year period after enactment of the ordinance. The citation data show that enforcement has continued over the study period although most of the secondary citations are dismissed.  Accident data show that the number of fatalities has been reduced after enactment of the law. The number of non-incapacitating injuries was also reduced with no reduction found in the number of incapacitating injuries. Comparing actual with projected numbers shows that the actual number of fatalities was 18 percent lower than the projected number with the number of non-incapacitating injuries 12 percent less than the projected number.

description: Global economic crisis has produced a large cohort of unemployed youth, who in 2009, stood ataround 181 million worldwide. The Kenyan ministry of youth affairs was created in December2005 with a mandate to fully develop the potential of the youth as well as prepare and engagethem in the socio- economic development of Kenya. Specific priority areas include empoweringthe youth to engage in economic activities through training and funding of youth projects,creating employment opportunities that benefit the youth and providing the youth with necessaryfinancial support and market linkages to their products. To ensure the youth get access to cheaploans, the youth enterprise development fund was created in December 2006 through a legalnotice. Many developing countries continue to spend scarce resources on youth loans that haveno proven impact. It is surprising that in spite the introduction of youth funds, many youths stillstruggle to get employment. Thus, this study was set to establish the influence of monitoring onfinancial sustainability of youth projects funded by YEDF in Maara Sub-County, TharakaNithiCounty, Kenya. The study established that youths not only require funding but also supervisionin form of monitoring and evaluation of the projects invested in by the funding financial firms toincrease the success of such projects. The results show that there was a statistically significantpositive correlation between current ratio and groups where projects funded by YEDF are oftenmonitored and evaluated by the officials from government(r = 0.276 at p = 0.030). This impliesthat groups where projects funded by YEDF are frequently monitored often record betterfinancial outcomes as opposed to those where monitoring and evaluation of such projects arerarely monitored and evaluated.

description: The septuple-atomic-layer $\mathrm{VSi_2P_4}$ with the same structure of experimentally synthesized $\mathrm{MoSi_2N_4}$ is predicted to be a spin-gapless semiconductor (SGS). In this work, the biaxial strain is applied to tune electronic properties of $\mathrm{VSi_2P_4}$, and it spans a wide range of properties upon the increasing strain from ferromagnetic metal (FMM) to SGS to ferromagnetic semiconductor (FMS) to SGS to ferromagnetic half-metal (FMHM). Due to broken inversion symmetry, the coexistence of ferromagnetism and piezoelectricity can be achieved in FMS $\mathrm{VSi_2P_4}$ with strain range of 0\% to 4\%. The calculated piezoelectric strain coefficients $d_{11}$ for 1\%, 2\% and 3\% strains are 4.61 pm/V, 4.94 pm/V and 5.27 pm/V, respectively, which are greater than or close to a typical value of 5 pm/V for bulk piezoelectric materials. Finally, similar to $\mathrm{VSi_2P_4}$, the coexistence of piezoelectricity and ferromagnetism can be realized by strain in the $\mathrm{VSi_2N_4}$ monolayer. Our works show that $\mathrm{VSi_2P_4}$ in FMS phase with intrinsic piezoelectric properties can have potential applications in spin electronic devices.

description: We review a concept of the Moscow potential (MP) of the $NN$ interaction. On the basis of this concept we derive by quantum inversion optical partial potentials from the modern partial-wave analysis (PWA) data and deuteron properties. Point-form (PF) relativistic quantum mechanics (RQM) is applied to the two-body deuteron photodisintegration. Calculations of the cross-section angular distributions cover photon energies between 1.1 and 2.5 GeV. Good agreement between our theory and recent experimental data confirms the concept of deep attractive Moscow potential with forbidden $S$- and $P$-states.

description: Transactive energy plays a key role in the operation and energy management of future power systems. However, the conventional operational mechanism, which follows a centralized design, is often less secure, vulnerable to malicious behaviors, and suffers from privacy leakage. In this work, we introduce blockchain technology in transactive energy to address these challenges. Specifically, we develop a novel blockchain-based transactive energy framework for prosumers and design a decentralized energy trading algorithm that matches the operation of the underlying blockchain system. We prove that the trading algorithm improves the individual benefit and guarantees the socially optimal performance, and thus incentivizes prosumers to join the transactive energy platform. Moreover, we evaluate the feasibility of the transactive energy platform throughout the implementation of a small-scale network of Internet of Things (IoT) devices and extensive simulations using real-world data. Our results show that this blockchain-based transactive energy platform is feasible in practice, and the decentralized trading algorithm reduces the user's individual cost by up to 77% and lowers the overall cost by 24%.

description: Statistical significance testing centered on p-values is commonly used to compare NLP system performance, but p-values alone are insufficient because statistical significance differs from practical significance. The latter can be measured by estimating effect size. In this paper, we propose a three-stage procedure for comparing NLP system performance and provide a toolkit, NLPStatTest, that automates the process. Users can upload NLP system evaluation scores and the toolkit will analyze these scores, run appropriate significance tests, estimate effect size, and conduct power analysis to estimate Type II error. The toolkit provides a convenient and systematic way to compare NLP system performance that goes beyond statistical significance testing

1993 Safety Belt Usage Survey and Evaluation of Effectiveness in Kentucky
Creators: name: Agent, Kenneth R.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1993
Subjects: subject: Transportation Engineering

description: The objective of the survey was to establish 1993 safety belt and child safety seat usage rates in Kentucky. Data were collected at 100 sites and combined based on vehicle miles travelled for a given type of highway, rural or urban location, and county population category. Also included in this report is an analysis of accident records evaluating the effectiveness of safety belts.  Statewide usage rates were 42 percent for drivers and front-seat passengers (over 19 years of age) and 61 percent for children under four years of age (front and rear seats). Driver usage rates increased in 1993 compared to 1992, however, the amount of the increase has decreased. Rates were highest on interstate highways and lowest on rural, non-interstate highways.  Benefits in the reduction of injures for occupants involved in police-reported accidents wearing a safety belt or in a safety seat were shown through the analysis of accident records. For example, a 54 percent reduction in fatal or incapacitating injuries was determined for drivers wearing a safety belt compared to those who were not restrained.  The increased usage that resulted in Fayette County, Jefferson County, Bardstown, Covington, and Bowling Green after enactment of local mandatory usage laws was shown. The recommendation is that a statewide mandatory safety belt law should be passed or, in lieu of a statewide law, additional local governments should pass such a law.

description: Red supergiants (RSGs) are an evolved stage in the life of intermediate massive stars (than than 25 solar masses). For many years, their location in the H-R diagram was at variance with the evolutionary models. Using the MARCS stellar atmospheres, we have determined new effective temperatures and bolometric luminosities for RSGs in the Milky Way, LMC, and SMC, and our work has resulted in much better agreement with the evolutionary models. We have also found evidence of significant visual extinction due to circumstellar dust. Although in the Milky Way the RSGs contribute only a small fraction (than than 1 percent) of the dust to the interstellar medium (ISM), in starburst galaxies or galaxies at large look-back times, we expect that RSGs may be the main dust source. We are in the process of extending this work now to RSGs of higher and lower metallicities using the galaxies M31 and WLM.

description: Severe mastitis is infection and inflammation of breast parenchymal cells. There is non-lactating andlactational mastitis majorly seen in women. It includes the breast tenderness, pain in the breast, theswelling in breast, high fever, and breast abscess. Mastitis is condition that majorly leads to severe painduring breastfeeding and hamper mother child bonding. Antibiotics, analgesic and antipyretics are choiceof treatment during mastitis. Breast mastitis can lead to local infection and cracked fissures in women’sbreast.Breast abscess is major symptom of severe mastitis which leads to entry of bacteria staphylococcus Aureusand negligence of breast care during pregnancy and postpartum period. Drug Ibuprofen is drug of choiceto treat mastitis and Tab. Paracetamol is used to reduce high fever. Proper breast support, regular breastcare, hand washing before and after breast feed should be used to prevent mastitis.Mastitis is condition where inflammation occurs of breast parenchymal cells in women. It includes highfever, tenderness in breast, and pain in breast, fluid accumulation, swelling and feeling of discomfort.Mastitis is rule out with different investigation breast examination, Culture swab, CBC investigation andbreast ultrasound.

description: We study the effects of spin transfer on thermally activated dynamics of magnetic nanopillars with identical thicknesses of the magnetic layers. The symmetric nanopillars exhibit anomalous dependencies of switching statistics on magnetic field and current. We interpret our data in terms of simultaneous current-induced excitation of both layers. We also find evidence for coupling between the fluctuations of the layers due to the spin transfer.

description: Τα τελευταία χρόνια γίνεται λόγος για την ικανότητα των μεσεγχυματικών στελεχιαίων κυττάρων (MSC)να μεταναστεύουν από την κυκλοφορία σε περιοχές ιστικής βλάβλης και να διαφοροποιούνται σε διάφορους κυτταρικούς τύπους ή να ασκούν ανοσορρυθμιστική δράση. Οπότε θεωρήθηκε σημαντικό να μελετηθεί ο ρόλος τους στην πειραματική αρθρίτιδα που αποτελεί ζωϊκό μοντέλο για τη διερεύνηση του μηχανισμού παθογένεσης της ρευματοειδούς αρθρίτιδας. Από την παρούσα εργασία προκύπτει ότι τα MSC δεν ασκούν καμία ευεργετική επίδραση στην εξέλιξη της ΑΑ παρά μόνο αν χορηγηθούν ενδομυελικά και προηγηθεί μερική μυελοκαταστολή. Επίσης, βρέθηκε ότι οι παράγοντες που εκκρίνουν τα MSC προκαλούν αναστολή του πολλαπλασιασμού των Τ-λεμφοκυττάρων in vitro. Ο G-CSF που είναι ένας αυξητικός παράγοντας, χάρη στις αντιφλεγμονώδεις ιδιότητές του, έχει ευεργετική δράση όταν χορηγηθεί πριν από την έναρξη συμπτωμάτωντης ΑΔ.
description: Mesenchymal stem cells (MSCs) have the ability to proliferate extensively in vitro and differentiate into many cell types. Upon tissue injury, MSCs have been shown to migrate to the damaged area. In addition to their differentiation capability, MSCs have been recently demonstrated to suppress several T-lymphocyte activities, thus exerting an immunoregulatory capacity both in vitro and in vivo. According to these findings, our study focuses on the role of MSCs in adjuvant arthritis (AA), a rat model for human rheumatoid arthritis.Our results suggest that intra-bone marrow administration of MSCs seems to reduce severity of the disease only if lympho-myelo-ablation (sublethal doses of Total Body Irradiation-TBI) occurs. In addition, it has been shown that MSCs, as immunosuppressant agents, inhibit the proliferation of T-cells in vitro and this inhibition seems to be greater in splenocytes derived from AA rats. G-CSG (granulocyte colony-stimulating factor), which is a growth factor, is considered beneficial for the prevention and/or treatment of autoimmune diseases. G-CSF seems to be effective in AA when it is administered at disease onset. In contrast with this, if G-CSF is administered after induction of AA or after disease stabilization, it causes severe inflammation.

description: The vulnerability to trawling on a species level is determined by a species' individual combination of biological traits that is related to the ecosystem functions. Trait-based indices of physical resistance RI and reproductive potential RPI were developed and combined into an overall vulnerability index on a species level, the RRI or Resistance and Reproductive Potential Index. The indices are used to explore how resistance and reproductive potentia change over a trawling gradient. The RRI allows for dividing the benthic community into groups expressing different levels of vulnerability that can be linked to ecosystem functions. The RRI index opens up the possibility of scenario modelling by simulating the extinction or loss of vulnerable species and its effects on functions. The validity of the trait-based RRI index was explored by comparing individual species' RRI scores to empirically observed responses over a trawling gradient based on a previously published data. RRI score and observed responses (regression slopes) were significantly correlated providing support for the rationality of the approach taken. Data analyses evidenced increases of resistance and resilience indices over the trawling gradient, demonstrating that communities lost vulnerable species with increasing trawling. When exploring the effects of trawling on the bioturbation, we found it to be disproportionately affected though the loss of vulnerable species. The proposed indices provide new insights into the link of species vulnerability and function.

Relationship between polytropic index and temperature anisotropy in space plasmas

description: The paper develops a theoretical relationship between the polytropic index and the temperature anisotropy that may characterize space plasmas. The derivation is based on the correlation among the kinetic energies of particles with velocities described by anisotropic kappa distributions. The correlation coefficient depends on the effective dimensionality of the velocity distribution function, having its shape determined by the temperature anisotropies caused by the ambient magnetic field; on the other hand, the effective dimensionality is directly dependent on the polytropic index. This analysis leads to the connection between the correlation coefficient, effective dimensionality of velocity space, and the polytropic index, with the ratio of temperature anisotropy. Moreover, a data and statistical analysis is performed to test the application of the theoretically developed model, in the solar wind proton plasma near 1 AU. The derived theoretical relationship is in good agreement with observations, showing that the lowest and classical value of the adiabatic polytropic index occurs in the isotropic case, while higher indices characterize anisotropic plasmas. Finally, possible extensions of the theory considering (i) non-adiabatic polytropic behavior, and (ii) more general distributions, are further discussed.
