Nudos y enredos : circuitos bárbaros y polémicas beligerantes en las revistas andinas de principios del siglo XX
Creators: name: Ortiz, Rodolfo

description: This dissertation is an investigation into the role of magazines in the early twentieth-century intellectual and cultural fields of the Andes. Based on the topology of knots and tangles, I look at the relationship between these magazines and this period's political and cultural transitions in the context of a questioning of the idea of an unviable modernity in the Andes. In a field of friction and entanglement, I analyze the formation of an “abigarrado” or motley zone and how magazines become a dispositif that crosses and undermines borders (and not only national borders), in favor of cultural multiplicity and segmentarity. From Gesta Bárbara (1918) in Potosí to Puno’s Boletín Titikaka (1926-1930), I examine how this dispositif operated in-between the literary and the political, in-between the visual field (both regional and cosmopolitan) and language, in-between insurgent movements (not only indigenous) and the nation-state… in short, in-between the aesthetic and political ideologies discussed and disputed in the interplay of avant-garde movements, political revolutions, and social transformations. I study the circuits of an intellectual barbarism that, through these magazines, (dis)articulates geopolitical paths. I also discuss the discursive heterogenization by which ideas are knotted as soon as their horizons become entangled or diluted. In this mechanism of varied velocities, I highlight the destituent power of an off-center and fugitive intellectuality embodied by Arturo Borda, Pablo Iturri Jurado, Óscar Cerruto, Eustaquio K'allata, Gamaliel Churata… a destituent power that pugnaciously escapes the political and cultural nets of its time.
The CDF dijet excess and Z'_{cs} coupled to the second generation quarks

description: Recently the CDF collaboration has reported the excess in the dijet invariant-mass distribution of the Wjj events, corresponding to a significance of 3.2 standard deviations. Considering the lack of similar excesses in the $γjj$ and $Z jj$ events yet, we propose a new Z' model: Z' couples only to the second generation quarks. Single production of $\zsc$ as well as associated production with $W,γ, Z$ are mainly from the sea quarks. Only $W Z'$ production has additional contribution from one valence quark and one sea quark, which is allowed by CKM mixing. We found that if the new gauge coupling is large enough, marginally permitted by perturbativity, this new model can explain the observed CDF $Wjj$ anomaly as well as the lack of $\gm jj$ and $Z jj$ anomalies. Vanishing coupling of Z'-b-b protects this model from the constraint of p pbar ->WH -> lνb \bar{b}.

description: Since 2019, the novel coronavirus outbreak has shaken the world to its core in terms of the deadly mortality and economic turbulence. On a positive note, national restriction measures to stem the spread of the virus have unexpectedly ameliorated the environment. One of the silver linings is that air pollution in many parts of the world has witnessed a substantial improvement, especially in the heavily polluted countries as in the case of Viet Nam. That being said, it does not take a rocket scientist to discern that in the absence of concrete environmental commitments and actions Viet Nam's air pollution will remain even if the COVID-19 has ebbed. This Article suggests that the COVID-19 pandemic should serve as a wake-up call for the Vietnamese authority to embrace sturdier and more vigorous environmental laws and policies to fully address the worsening air pollution in the country. Thereby it also makes some recommendations for Viet Nam in this respect.
High dye removal capacity of Peniophora laxitexta immobilized in a combined support based on polyurethane foam and lignocellulosic substrates

description: Dye removal from effluents is a major problem for most textile industries. At present, wastewater treatments are currently based on physico-chemical methods which are expensive, energy inefficient and of limited versatility. The aim of this work was to find a low-cost and efficient method for dye removal. To do this, we designed a combined system based on the immobilization of the ligninolytic white-rot fungus Peniophora laxitexta (BAFC 4687) on mixed supports consisting of two polyurethane foam discs and a middle layer of diverse lignocellulosic substrates: soybean hulls, wheat straw or cellulose spent casings. As a corticioid fungus, P. laxitexta was able to completely colonize the supports developing a compact and tight structure that maintained the integrity of the system after several dye removal cycles. The immobilized fungus removed between 30% and 50% of the azoic dye Xylidine and more than 50% of the anthraquinonic dye RBBR in three successive cycles, and near 90% of the triphenylmethane Malachite Green in 10 repeated cycles without any loss of efficiency. Our analysis showed that the removal of the dyes was due to the combined effect of adsorption to the supports and enzymatic decolorization by soluble laccases and enzymes associated with the mycelium. Additionally, we showed that the presence of Malachite Green induced the expression of a new laccase isoform with high decolorization capacity. Based on these results, we propose that this inoculated laminar biocarrier could be effectively used for dye removal in textile wastewater.

description: Mathematical models of the thermal state of the air cooler with allowance for air humidity for countercurrent, direct-flow and cross flow schemes of heat carriers have been developed. On the basis of these mathematical models, an appropriate method for calculating the intermediate air coolers of GTU is presented. The methodical features of the calculation of multi-pass heat exchangers are indicated. The sufficiently high accuracy of the calculations is ensured by using a specially developed method for calculating the heat capacity of moist air during its cooling. On the basis of the developed techniques, the calculation of moisture release in the intermediate air cooler in the process of air cooling was carried out.
Spectral Analysis of Large-Scale Solar Flows and Surface-Convection

description: Vigorous turbulent convection near the solar surface excites acoustic waves that propagate through the solar interior and form a large discrete set of resonant modes. High-precision measurements of these modes have been carried out for decades, enabling the imaging of the solar interior using helioseismology. Flows and deviations from purely radial stratification act as perturbations that modify these modes. Global helioseismic normal-mode coupling promises to be a modern tool that enables the estimation of all physical perturbations such as flows, structure and magnetic fields. Differential rotation, the dominant global-scale axisymmetric perturbation, which plays a crucial role in modulating the large-scale solar magnetic field, has been tightly constrained primarily using measurements of mode-frequency splittings. However, the frequency-splitting formalism invokes the approximation that modes are isolated, which becomes increasingly inaccurate for modes at high angular degrees. Such modes dominantly propagate in the shallow depths near the surface, thereby influencing the inferences of structure and rotation in this region. While the effects of coupling have been estimated to be reasonably small through analytical estimates, a full-blown analysis of the inaccuracy of the assumption was impracticable due to prohibitively expensive computing and can be historically attributed to legacy computing architecture, limited memory and inefficient algorithms. Using modern computing architecture with a massive memory bandwidth, we set up a parallel computation on large HPC compute nodes, to analyse eigenfunction corrections, which respect cross-coupling of modes across multiplets. A successful estimation of differential rotation establishes the method of normal-mode coupling as a valid probe for measuring large-scale flows, internal structure and dynamics. We show that, surprisingly, if structure perturbations are ignored, mode-coupling does not affect the inference of rotation. Consequently, we also demonstrate that, at shallow depths, mode-coupling breaks the selections rules that enabled a simple disentangling of flows, structure and magnetic fields from observations, highlighting the need for a simultaneous estimation of all these features. We also propose a framework for the measurement of meridional circulation through mode-coupling which is enabled by our modelling of the Center-to-Limb systematic.
Early anisotropic hydrodynamics and the RHIC early-thermalization and HBT puzzles

description: We address the problem if the early thermalization and HBT puzzles in relativistic heavy-ion collisions may be solved by the assumption that the early dynamics of the produced matter is locally anisotropic. The hybrid model describing the purely transverse hydrodynamic evolution followed by the perfect-fluid hydrodynamic stage is constructed. The transition from the transverse to perfect-fluid hydrodynamics is described by the Landau matching conditions applied at a fixed proper time. The global fit to the RHIC data reproduces the soft hadronic observables (the pion, kaon, and the proton spectra, the pion and kaon elliptic flow, and the pion HBT radii) with the accuracy of about 20%. These results indicate that the assumption of the very fast thermalization may be relaxed. In addition, the presented model suggests that a large part of the inconsistencies between the theoretical and experimental HBT results may be removed.

description: Groundwater is the only source of high quality water for human consumption in most parts of the world; however, it can be easily contaminated by domestic, industrial, and agricultural wastes such as fertilisers and pesticides. The main objective of the present research was to study the photocatalytic removal of 2,4-Dichlorophenoxyacetic acid pesticide (2,4-D) from aqueous media. This was a laboratory scale study in which the zinc oxide nanoparticles were doped with 0.5, 1, and 2 molar percent of tungsten oxide. The nanoparticles synthesised were characterised using powder XRD, SEM, FTIR, and UV-Vis Spectroscopy analyses. During the photodegradation of 2,4-D, the operational parameters studied were pH, nanoparticles dosage, initial pesticide concentration, light intensity, contact time, and the mineralisation trend of organic matter. It was found that the doped nanoparticles had a smaller band gap energy, which confirms the effect of doping. The percentage of the dopant can affect the pesticide removal efficiency. The optimal pH value obtained was 7. In addition, the process efficiency, increased from 27% to 78% with increasing UV light intensity from 172 to 505 W/m2 respectively. Moreover, it was found that, with increasing light intensity, contact time and nanoparticle concentration all caused the pesticide removal efficiency to be increased too. In addition, the increase of the pesticide concentration would cause a reduction in the process removal efficiency. This study indicated that the photocatalytic process using tungsten doped zinc oxide nanoparticles can remove the 2,4-D pesticide by around 80% from the aquatic environment.

description: Biochar is known to be a highly adsorptive material, especially when the biochar is altered by activation to further increase its sorption ability. Little information, however, is available on the potential reversibility of both ammonium (NH4+) and nitrate (NO3−) sorption on the inherent biochar pH. The objective of our study was to characterise biochars made using different pyrolysis conditions from five various plant materials and rubber tyre, and to use them to investigate the biochar properties responsible for NH4+ and NO3− adsorption and desorption. The rubber tyre, maize stover and sugarcane pith were the weakest adsorbing biochars (5.7–7.8 mg g−1) and best described by the Freundlich adsorption isotherm. The grape pip, grape skin and pine wood biochars had adsorption capacities in the range 8.3–9.4 mg NH4+ g−1 and best described by a linear adsorption isotherm at 100 mg L−1. The NH4+ adsorption results were associated with physisorption which implies that they can act as slow release NH4+ fertilisers if NH4+ is bioavailable. The six biochars had NO3− adsorption capacities in the range 15.2–15.9 mg g−1 and were well fitted to the linear adsorption isotherm at 100 mg L−1. All six biochars had a stronger NO3− removal affinity (82–89%) compared to NH4+ (33–39%). Adsorbed nitrate was not desorbable (0.01–0.23%) compared to adsorbed NH4+ which was 53–60% desorbable. The desorption result was possibly due to NO3− competing redox reactions or NO3− being too strongly adsorbed for extraction. Desorption of NH4+ was associated with biochar net negative pH values and volatilisation of ammonia.

description: Gaugino AMSB models-- wherein scalar and trilinear soft SUSY breaking terms are suppressed at the GUT scale while gaugino masses adopt the AMSB form-- yield a characteristic SUSY particle mass spectrum with light sleptons along with a nearly degenerate wino-like lightest neutralino and quasi-stable chargino. The left- sleptons and sneutrinos can be pair produced at sufficiently high rates to yield observable signals at the Fermilab Tevatron. We calculate the rate for isolated single and dilepton plus missing energy signals, along with the presence of one or two highly ionizing chargino tracks. We find that Tevatron experiments should be able to probe gravitino masses into the ~55 TeV range for inoAMSB models, which corresponds to a reach in gluino mass of over 1100 GeV.

description: Necessary and sufficient conditions for the nonclassicality of bosonic quantum states are formulated by introducing nonclassicality filters and nonclassicality quasiprobability distributions. Regular quasiprobabilities are constructed from characteristic functions which can be directly sampled by balanced homodyne detection. Their negativities uncover the nonclassical effects of general quantum states. The method is illustrated by visualizing the nonclassical nature of a squeezed state.

description: We propose a surface-edge state theory for half quantized Hall conductance of surface states in topological insulators. The gap opening of a single Dirac cone for the surface states in a weak magnetic field is demonstrated. We find a new surface state resides on the surface edges and carries chiral edge current, resulting in a half-quantized Hall conductance in a four-terminal setup. We also give a physical interpretation of the half quantized conductance by showing that this state is the product of splitting of a boundary bound state of massive Dirac fermions which carries a conductance quantum.

description: Introduction: The Canadian National Vaccine Safety (CANVAS) network collects seasonal influenza vaccine safety data from adults and children across Canada each year. Health events are evaluated between a vaccinated group and an unvaccinated group using data from online surveys. This thesis aims to describe the rate of severe health events and the most severe symptoms following seasonal influenza vaccination compared to an unvaccinated group of children and pregnant people. In addition, it aims to determine the agreement between symptoms reported in the online survey and a follow-up telephone report. Methods: Uncorrelated data from the CANVAS network were analyzed from 2013/2014 to 2019/2020. The outcome of interest was a severe health event that prevented/stopped daily activities, missed school, or required medical consultation. Incidence rate ratios and logistic regressions were conducted for both groups of interest to determine the association between vaccination status and severe health events. The sensitivity, specificity, and kappa estimate were calculated to determine the agreement for the most severe symptom, diagnosis, and treatment. Results: The unadjusted rate ratio for severe health events in children who received the inactivated influenza vaccine (IIV) compared to unvaccinated children was 1.22 (1.10, 1.34). However, no differences were observed in children who received the live attenuated influenza vaccine (LAIV) compared to an unvaccinated child group. The adjusted odds ratio (OR) for severe health events in children who received IIV compared to unvaccinated children was 1.11 (1.00, 1.25), and 1.11 (0.95, 1.29) in children who received LAIV compared to unvaccinated children. The agreement between child responses in the self-report online survey and the telephone report was moderate-to-high in both vaccinated and unvaccinated participants combined. The unadjusted rate ratio for severe health events in vaccinated pregnant people compared to unvaccinated pregnant people was 1.00 (0.64, 1.58). The adjusted OR for severe health events in vaccinated compared to unvaccinated pregnant people was 0.95 (0.59, 1.53). Conclusion: The findings show no association between the seasonal influenza vaccine and severe health events in children and pregnant people in Canada. There was moderate to high agreement of child responses between the online survey and the telephone report.

description: Spontaneously formed equilibrium nanopatterns with long-range order are widely observed in a variety of systems, but their pronounced temperature dependence remains an impediment to maintain such patterns away from the temperature of formation. Here, we report on a highly ordered stress-induced stripe pattern in a two-component, Pd-O, adsorbate monolayer on W(110), produced at high temperature and identically preserved at lower temperatures. The pattern shows a tunable period (down to 16 nm) and orientation, as predicted by a continuum model theory along with the surface stress and its anisotropy found in our DFT calculations. The control over thermal fluctuations in the stripe formation process is based on the breaking/restoring of ergodicity in a high-density lattice gas with long-range interactions upon turning off/on particle exchange with a heat bath.

description: We study the entangled states that can be generated using two species of atoms trapped in independently movable, two-dimensional optical lattices. We show that using two sets of measurements it is possible to measure a set of entanglement witness operators distributed over arbitrarily large regions of the lattice, and use these witnesses to produce two-dimensional plots of the entanglement content of these states. We also discuss the influence of noise on the states and on the witnesses, as well as connections to ongoing experiments.

description: Dye removal from effluents is a major problem for most textile industries. At present, wastewater treatments are currently based on physico-chemical methods which are expensive, energy inefficient and of limited versatility. The aim of this work was to find a low-cost and efficient method for dye removal. To do this, we designed a combined system based on the immobilization of the ligninolytic white-rot fungus Peniophora laxitexta (BAFC 4687) on mixed supports consisting of two polyurethane foam discs and a middle layer of diverse lignocellulosic substrates: soybean hulls, wheat straw or cellulose spent casings. As a corticioid fungus, P. laxitexta was able to completely colonize the supports developing a compact and tight structure that maintained the integrity of the system after several dye removal cycles. The immobilized fungus removed between 30 to 50% of the azoic dye Xylidine and more than 50% of the anthraquinonic dye RBBR in three successive cycles, and near 90% of the triphenylmethane Malachite Green in 10 repeated cycles without any loss of efficiency. Our analysis showed that the removal of the dyes was due to the combined effect of adsorption to the supports and enzymatic decolorization by soluble laccases and enzymes associated with the mycelium. Additionally, we showed that the presence of Malachite Green induced the expression of a new laccase isoform with high decolorization capacity. Based on these results, we propose that this inoculated laminar biocarrier could be effectively used for dye removal in textile wastewater.

description: The study of fast, eruptive events in the low solar corona is one of the science objectives of the Atmospheric Imaging Assembly (AIA) imagers on the recently launched Solar Dynamics Observatory (SDO), which take full disk images in ten wavelengths with arcsecond resolution and 12 sec cadence. We study with AIA the formation of an impulsive coronal mass ejection (CME) which occurred on June 13, 2010 and was associated with an M1.0 class flare. Specifically, we analyze the formation of the CME EUV bubble and its initial dynamics and thermal evolution in the low corona using AIA images in three wavelengths (171, 193 and 211 A). We derive the first ultra-high cadence measurements of the temporal evolution of the CME bubble aspect ratio (=bubble-height/bubble-radius). Our main result is that the CME formation undergoes three phases: it starts with a slow self-similar expansion followed by a fast but short-lived (~ 70 sec) period of strong lateral over-expansion which essentially creates the CME. Then the CME undergoes another phase of self-similar expansion until it exits the AIA field of view. During the studied interval, the CME height-time profile shows a strong, short-lived, acceleration followed by deceleration. The lateral overexpansion phase coincides with the deceleration phase. The impulsive flare heating and CME acceleration are closely coupled. However, the lateral overexpansion of the CME occurs during the declining phase and is therefore not linked to flare reconnection. In addition, the multi-thermal analysis of the bubble does not show significant evidence of temperature change.

description: Since 2019, the novel coronavirus outbreak has shaken the world to its core in terms of the deadly mortality and economic turbulence. On a positive note, national restriction measures to stem the spread of the virus have unexpectedly ameliorated the environment. One of the silver linings is that air pollution in many parts of the world has witnessed a substantial improvement, especially in the heavily polluted countries as in the case of Viet Nam. That being said, it does not take a rocket scientist to discern that in the absence of concrete environmental commitments and actions Viet Nam's air pollution will remain even if the COVID-19 has ebbed. This Article suggests that the COVID-19 pandemic should serve as a wake-up call for the Vietnamese authority to embrace sturdier and more vigorous environmental laws and policies to fully address the worsening air pollution in the country. Thereby it also makes some recommendations for Viet Nam in this respect.

COs outside of the realm of citizen science have been operating for decades as instruments of public participation in both social and environmental monitoring fields. ICTs and new technologies increase the exponential impact of CSPs-COS. There are great expectations about their ability to impact the performance of citizen science, as a research infrastructure and as a way to facilitate the governance of commons resources.

The main objective of the present research was to study the photocatalytic removal of 2,4-Dichlorophenoxyacetic acid pesticide (2,4-D) from aqueous media. This was a laboratory scale study in which the zinc oxide nanoparticles were doped with 0.5, 1, and 2 molar percent of tungsten oxide. The nanoparticles synthesized were characterized using powder XRD, SEM, FTIR, and UV-Vis Spectroscopy analyses. During the photodegradation of 2,4-D, the operational parameters studied were pH, nanoparticles dosage, initial pesticide concentration, light intensity, contact time, and the mineralization trend of organic matter. It was found that the doped nanoparticles had a smaller band gap energy, which confirms the effect of doping. The percentage of the dopant can affect the pesticide removal efficiency. The optimal pH value obtained was 7. In addition, the process efficiency, increased from 27 to 78% with increasing UV light intensity from 172 to 505 W/m2 respectively. Moreover, it was found that, with increasing light intensity, contact time and nanoparticle concentration all caused the pesticide removal efficiency to be increased too. In addition, the increase of the pesticide concentration would cause a reduction in the process removal efficiency. This study indicated that the photocatalytic process using tungsten doped zinc oxide nanoparticles can remove the 2,4-D pesticide by around 80% from the aquatic environment.

description: In the pure spinor formalism for the superstring, the b antighost is necessary for multiloop amplitude computations and is a composite operator constructed to satisfy {Q,b}=T where Q is the BRST operator and T is the holomorphic stress-tensor. In superstring backgrounds with only NS-NS fields turned on, or in flat space, one needs to introduce "non-minimal" variables in order to construct the b antighost. However, in Type II backgrounds where the Ramond-Ramond bispinor field-strength satisfies certain conditions, the b antighost can be constructed without the non-minimal variables. Although the b antighost in these backgrounds is not holomorphic, its antiholomorphic derivative is BRST-trivial. We discuss the properties of this operator both in the AdS_5 x S^5 background and in a generic curved background.

description: Apoptosis, repair and senescence are tools which an organism can use in a risk management process that balances the threats posed by damaged, existing cells against the difficulty and cost of replacing them. If they are orchestrated effectively the organism can gain a degree of risk reduction, appropriate for a particular tissue and time of life, at minimum cost.
Where abundant resources allow, apoptosis eliminates risks posed by damaged, high-entropy cells. Where resources are constrained, senescence trades immediate threats posed by damaged cells for longer-term risks including inflammation, metastasis and epigenetic instability. Pushing risks into the future is consistent with an evolutionary need to keep an organism adequately healthy, for sufficiently long, that it can raise healthy offspring.
An organism which has reserves of, e.g., stem cells and telomeres, can manufacture pristine, low-entropy cells to replace damaged, higher-entropy cells eliminated by apoptosis. This mechanism will minimise cellular entropy, and retain cellular information, until the reserves are exhausted. Plentiful initial resources, and careful management of those resources, can delay but not eliminate the increase in cellular entropy and reduction in information as an organism ages. Increased risk, increased entropy and reduced information are closely related features of the aging process. Cellular entropy might act as a measure of ‘risk’ in the discussion presented here while the energy invested to reduce cellular entropy acts as a measure of ‘cost’.
