description: Este proyecto tiene como base fundamental la música como herramienta lúdico-pedagógica en el grado primero de primaria para potencializar los procesos de enseñanza y aprendizaje en la fundación instituto mixto el nazareno, de la cual se deriva el interrogante: ¿Cómo articular la música como herramienta lúdico-pedagógica para mejorar las estrategias en el proceso de enseñanza-aprendizaje de los niños?, por ello se propone la continuidad en el uso de la lúdica, sabiendo que son niños y por ende necesitan una motivación efectiva, para aprender de forma divertida y dinámica; además, es de gran importancia en el proceso pedagógico, porque a través de la música los niños además del aprendizaje, crean ambientes sanos, que les permiten desarrollarse social, emocional e intelectualmente. Los fundamentos teóricos base son: Piaget, Vygotsky, Ausubel (teoría del aprendizaje significativo), Maslow (teoría de la motivación), Gardner (inteligencias múltiples) y Carl Orff, Zoltan Kodály (teoría musical). Este trabajo de investigación tiene un enfoque cualitativo – descriptivo utilizando como instrumentos, la observación, las actividades pedagógicas, talleres con docentes y padres de familia, y encuesta aplicadas a una población de estudiantes y maestras del grado primero del Instituto Mixto el Nazareno de la ciudad de Cartagena. Los resultados obtenidos han sido que los niños presentaron mejoría en la motivación afectando positivamente su desempeño en el desarrollo académico y al tiempo los docentes se fortalecieron en sus estrategias en este proceso demostrando que las herramientas lúdico-musicales realmente potencializan los procesos pedagógicos, creando personalidad en los niños.

description: The geoelectric properties of the geothermal system associated with the Tolhuaca volcano were investigated by three-dimensional (3D) inversion of magnetotelluric (MT) data. This study presents the first resistivity model of the Tolhuaca volcano derived from 3D MT inversion to have a better understanding of its magmatic and hydrothermal system. We selected data from 54 MT stations for 3D inversion. We performed a series of 3D MT inversion tests by changing the type of data to be inverted, as well as the starting model to obtain a model in agreement with the geology. The final 3D MT model presents a conductive body (<20 Ωm) located 2 km below the summit of Tolhuaca volcano, inferred as a shallow magmatic storage compartment. We also distinguish a ~300 m thick layer of high conductivity (<10 Ωm) corresponding to argillic hydrothermal alteration. The MT model includes two resistive bodies (~200 Ωm) in the upper crust below the laterally displaced argillic alteration layer to the west beneath the extinct Tolhuaca, which would correspond to a shallow reservoir (~1000 m from the surface) and a deep reservoir (>1800 m from the surface) that had so far not been identified by previous resistivity models. The result of this study provides new insights into the complexity of the Tolhuaca geothermal system.

description: Recently, it has been found that off-centre carbon burning in a subset of intermediate-mass stars does not propagate all the way to the center, resulting in a class of hybrid CONe cores. Here, we consider the possibility that stars hosting these hybrid CONe cores might belong to a close binary system and, eventually, become white dwarfs accreting from a non-degenerate companion at rates leading to a supernova explosion. We have computed the hydrodynamical phase of the explosion of Chandrasekhar-mass white dwarfs harboring hybrid cores, assuming that the explosion starts at the center, either as a detonation (as may be expected in some degenerate merging scenarios) or as a deflagration (that afterwards transitions into a delayed detonation). We assume these hybrid cores are made of a central CO volume, of mass M(CO), surrounded by an ONe shell. We show that, in case of a pure detonation, a medium-sized CO-rich region, M(CO)<0.4 Msun, results in the ejection of a small fraction of the mantle while leaving a massive bound remnant. Part of this remnant is made of the products of the detonation, Fe-group nuclei, but they are buried in its inner regions, unless convection is activated during the ensuing cooling and shrinking phase of the remnant. In contrast, and somehow paradoxically, delayed detonations do not leave remnants but for the minimum M(CO) we have explored, M(CO)=0.2 Msun, and even in this case the remnant is as small as 0.13 Msun. The ejecta produced by these delayed detonations are characterized by slightly smaller masses of 56Ni and substantially smaller kinetic energies than obtained for a delayed detonation of a 'normal' CO white dwarf. The optical emission expected from these explosions would hardly match the observational properties of typical Type Ia supernovae, although they make interesting candidates for the subluminous class of SN2002cx-like or SNIax.

description: (1) Background: Rural areas are characterised by a higher number of volunteers compared to urban centres in Germany. In this context, cultural and arts education is one of the largest voluntary sectors. However, an increasing decline in (cultural) volunteering can be observed. To counteract the decrease, it is important to strengthen regional cooperation and social networks, which are based on trust. The connection between trust, volunteering, and social networks has already been examined, but we still do not fully understand the emergence of trust in the link of cultural education cooperation and networks in rural areas. (2) Methods: A total of 34 semi-structured interviews in combination with egocentric network maps were conducted in four rural regions. The interview data were audio-recorded, transcribed, and analysed using qualitative content analysis. (3) Results: Four dimensions of trust-building were identified: 1. presence and spatial proximity, 2. multiplexity, 3. third party, and 4. community spirit.

description: Organometallic approaches are of ongoing interest for the development of novel functional 99mTc radiopharmaceuticals, while the basic organotechnetium chemistry seems frequently to be little explored. Thus, structural and reactivity studies with the long-lived isotope 99Tc are of permanent interest as the foundation for further progress in the related radiopharmaceutical research with this artificial element. Particularly the knowledge about the organometallic chemistry of high-valent technetium compounds is scarcely developed. Here, phenylimido complexes of technetium(V) with different isocyanides are introduced. They have been synthesized by ligand-exchange procedures starting from [Tc(NPh)Cl3(PPh3)2]. Different reactivity patterns and products have been obtained depending on the steric and electronic properties of the individual ligands. This involves the formation of 1:1 and 1:2 exchange products of Tc(V) with the general formulae [Tc(NPh)Cl3(PPh3)(isocyanide)], cis- or trans-[Tc(NPh)Cl3(isocyanide)2], but also the reduction in the metal and the formation of cationic technetium(I) complex of the formula [Tc(isocyanide)6]+ when p-fluorophenyl isocyanide is used. The products have been studied by single-crystal X-ray diffraction and spectroscopic methods, including IR and multinuclear NMR spectroscopy. DFT calculations on the different isocyanides allow the prediction of their reactivity towards electron-rich and electron-deficient metal centers by means of the empirical SADAP parameter, which has been derived from the potential energy surface of the electron density on their potentially coordinating carbon atoms.

description: The problem of increasing health care costs and decreasing access to health care services is a major crisis in the U.S. today. One factor contributing to the rising cost of health care is the inappropriate use of emergency rooms, (ERs). In response to escalating costs a local health care corporation implemented a telephone triage program called the After Hours Program, (AHP). The goal of the program was to reduce inappropriate utilization of emergency rooms, and to educate patients to recognize and treat specific health problems independently, i.e., home treatment.

A program evaluation was completed in which different dimensions of patient satisfaction were measured including accessibility, interpersonal care and technical skill of the nursing staff, as well as convenience of alternate treatment facilities. Almost 90% of those surveyed rated the program as very good or excellent, and 99% of respondents stated they would call the nurses again for advice. The study indicated that patients are satisfied with the AHP, and the results warrant incorporation into the program's quality improvement plan.

description: The arylation of carboxylic acid derivatives via Smiles rearrangement has gained great interest in recent years. Both radical and ionic approaches, as well as radical-polar crossover concepts, have been developed. In contrast, a reversed polar-radical crossover approach remains underexplored. Here we report a simple, efficient and scalable method for the preparation of sterically hindered and valuable α-quaternary amides via a polar-radical crossover-enolate oxidation-aryl migration pathway. A variety of easily accessible N-alkyl and N-arylsulfonamides are reacted with disubstituted ketenes to give the corresponding amide enolates, which undergo upon single electron transfer oxidation, a 1,4-aryl migration, desulfonylation, hydrogen atom transfer cascade to provide α-quaternary amides in good to excellent yields. Various mono- and di-substituted heteroatom-containing and polycyclic arenes engage in the aryl migration reaction. Functional group tolerance is excellent and substrates as well as reagents are readily available rendering the method broadly applicable.

description: We evaluate the difference between the Casimir free energies corresponding to either grounded or isolated perfect conductors, at high temperatures. We show that a general and simple expression for that difference can be given, in terms of the electrostatic capacitance matrix for the system of conductors. For the case of close conductors, we provide approximate expressions for that difference, by evaluating the capacitance matrix using the proximity force approximation. Since the high-temperature limit for the Casimir free energy for a medium described by a frequency-dependent conductivity diverging at zero frequency coincides with that of an isolated conductor, our results may shed light on the corrections to the Casimir force in the presence of real materials.

description: This study investigated whether sphingosine is effective as prophylaxis against Aspergillus spp. and Candida spp. In vitro experiments showed that sphingosine is very efficacious against A. fumigatus and Nakeomyces glabrataa (formerly named C. glabrata). A mouse model of invasive aspergillosis showed that sphingosine exerts a prophylactic effect and that sphingosine-treated animals exhibit a strong survival advantage after infection. Furthermore, mechanistic studies showed that treatment with sphingosine leads to the early depolarization of the mitochondrial membrane potential (Δψm) and the generation of mitochondrial reactive oxygen species and to a release of cytochrome C within minutes, thereby presumably initiating apoptosis. Because of its very good tolerability and ease of application, inhaled sphingosine should be further developed as a possible prophylactic agent against pulmonary aspergillosis among severely immunocompromised patients.

description: A detailed analysis of the electronic structure and decay dynamics in a symmetric system with three electrons in three linearly aligned binding sites representing quantum dots (QDs) is given. The two outer A QDs are two-level potentials and can act as (virtual) photon emitters, whereas the central B QD can be ionized from its one level into a continuum confined on the QD axis upon absorbing virtual photons in the inter-Coulombic decay (ICD) process. Two scenarios in such an ABA array are explored. One ICD process is from a singly excited resonance state, whose decay releasing one virtual photon we find superimposed with resonance energy transfer among both A QDs. Moreover, the decay-process manifold for a doubly excited (DE) resonance is explored, in which collective ICD among all three sites and excited ICD among the outer QDs engage. Rates for all processes are found to be extremely low, although ICD rates with two neighbors are predicted to double compared to ICD among two sites only. The slowing is caused by Coulomb barriers imposed from ground or excited state electrons in the A sites. Outliers occur on the one hand at short distances, where the charge transfer among QDs mixes the possible decay pathways. On the other hand, we discovered a shape resonance-enhanced DE-ICD pathway, in which an excited and localized B∗ shape resonance state forms, which is able to decay quickly into the final ICD continuum.
Chiral Exact Relations for Helicities in Hall Magnetohydrodynamic Turbulence

description: Besides total energy, three-dimensional incompressible Hall magnetohydrodynamics (MHD) possesses two inviscid invariants which are the magnetic helicity and the generalized helicity. New exact relations are derived for homogeneous (non-isotropic) stationary Hall MHD turbulence (and also for its inertialess electron MHD limit) with non-zero helicities and in the asymptotic limit of large Reynolds numbers. The universal laws are written only in terms of mixed second-order structure functions, i.e. the scalar product of two different increments. It provides, therefore, a direct measurement of the dissipation rates for the corresponding invariant flux. This study shows that the generalized helicity cascade is strongly linked to the left polarized fluctuations while the magnetic helicity cascade is linked to the right polarized fluctuations.

description: Cryptosporidiosis is a water- and food-borne zoonotic disease caused by the protozoon parasite of the genus Cryptosporidium. C. hominis and C. parvum are the main two species causing infections in humans and animals. The disease can be transmitted by the fecal–oral route as well as the respiratory route. The infective stage (sporulated oocysts) is resistant to different disinfectants including chlorine. Currently, no effective therapeutic drugs or vaccines are available to treat and control Cryptosporidium infection. To prevent cryptosporidiosis in humans and animals, we need to understand better how the disease is spread and transmitted, and how to interrupt its transmission cycle. This review focuses on understanding cryptosporidiosis, including its infective stage, pathogenesis, life cycle, genomics, epidemiology, previous outbreaks, source of the infection, transmission dynamics, host spectrum, risk factors and high-risk groups, the disease in animals and humans, diagnosis, treatment and control, and the prospect of an effective anti-Cryptosporidium vaccine. It also focuses on the role of the One Health approach in managing cryptosporidiosis at the animal–human–environmental interface. The summarized data in this review will help to tackle future Cryptosporidium infections in humans and animals and reduce the disease occurrence.

description: Recently it has been reported that the tumor adjacent colon tissues of 1,2-dymethylhydrazine induced (DMH)-rats revealed a high paracellular permeability. We hypothesized that the changes might be induced by cytokines. Colorectal cancer is accompanied by an increase in tumor necrosis factor alpha (TNFα) and interleukin 10 (IL10) that exert opposite regulatory effects on barrier properties of the colon, which is characterized by morphological and functional segmental heterogeneity. The aim of this study was to analyze the level of TNFα and IL10 in the colon segments of DMH-rats and to investigate their effects on barrier properties of the proximal and distal parts of the colon in healthy rats. Enzyme immunoassay analysis showed decreased TNFα in tumors in the distal part of the colon and increased IL10 in proximal tumors and in non-tumor tissues. Four-hour intraluminal exposure of the colon of healthy rats with cytokines showed reduced colon barrier function dependent on the cytokine: TNFα decreased it mainly in the distal part of the colon, whereas IL10 decreased it only in the proximal part. Western blot analysis revealed a more pronounced influence of IL10 on tight junction (TJ) proteins expression by down-regulation of the TJ proteins claudin-1, -2 and -4, and up-regulation of occludin only in the proximal part of the colon. These data may indicate a selective role of the cytokines in regulation of the barrier properties of the colon and a prominent role of IL10 in carcinogenesis in its proximal part.

description: Single eukaryotic cells commonly sense and follow chemical gradients, performing chemotaxis. Recent experiments and theories, however, show that even when single cells do not chemotax, clusters of cells may, if their interactions are regulated by the chemoattractant. We study this general mechanism of "collective guidance" computationally with models that integrate stochastic dynamics for individual cells with biochemical reactions within the cells, and diffusion of chemical signals between the cells. We show that if clusters of cells use the well-known local excitation, global inhibition (LEGI) mechanism to sense chemoattractant gradients, the speed of the cell cluster becomes non-monotonic in the cluster's size - clusters either larger or smaller than an optimal size will have lower speed. We argue that the cell cluster speed is a crucial readout of how the cluster processes chemotactic signal; both amplification and adaptation will alter the behavior of cluster speed as a function of size. We also show that, contrary to the assumptions of earlier theories, collective guidance does not require persistent cell-cell contacts and strong short range adhesion to function. If cell-cell adhesion is absent, and the cluster cohesion is instead provided by a co-attraction mechanism, e.g. chemotaxis toward a secreted molecule, collective guidance may still function. However, new behaviors, such as cluster rotation, may also appear in this case. Together, the combination of co-attraction and adaptation allows for collective guidance that is robust to varying chemoattractant concentrations while not requiring strong cell-cell adhesion.

description: Molecular dynamics (MD) simulations have become popular in materials science, biochemistry, biophysics and several other fields. Improvements in computational resources, in quality of force field parameters and algorithms have yielded significant improvements in performance and reliability. On the other hand, no method of research is error free. In this review, we discuss a few examples of errors and artifacts due to various sources and discuss how to avoid them. Besides bringing attention to artifacts and proper practices in simulations, we also aim to provide the reader with a starting point to explore these issues further. In particular, we hope that the discussion encourages researchers to check software, parameters, protocols and, most importantly, their own practices in order to minimize the possibility of errors. The focus here is on practical issues.

Habitat and distribution
Soil-dwelling species with a preference for mountain habitats. It was collected from the central and eastern Pyrenees (Denis 1930; Condé & Mathieu 1957; Sendra & Jiménez 1986). Outside the Pyrenees, C. giardi is cited from two localities at Durham, NE England (Bagnall 1915) and from two further localities in France: a mine of Gard and in a humid cave near Nancy (Husson 1946), but Condé (1956a) considered that they needed to be revised.

description: The synthesis and physical properties of two new and one known Ir-Sn-Se compound are reported. Their crystal structures are elucidated with transmission electron microscopy and powder X-ray diffraction. IrSn0.45Se1.55 is a pyrite phase which consists of tilted corner-sharing IrX6 octahedra with randomly distributed (Sn-Se)4- and (Se-Se)2- dimers. Ir2Sn3Se3 is a trigonally distorted skutterudite that consists of cooperatively tilted corner-sharing IrSn3Se3 octahedra with ordered (Sn-Se)24- tetramers. Ir2SnSe5 is a layered, distorted \b{eta}-MnO2 (pyrolusite) structure consisting of a double IrSe6 octrahedral row, corner-sharing in the a direction and edge-sharing in the b direction. This distorted pyrolusite contains (Se-Se)2- dimers, Se2- anions, and each double row is "capped" with a (Sn-Se)n polymeric chain. Resistivity, specific heat, and magnetization measurements show that all three have insulating and diamagnetic behavior, indicative of low spin 5d6 Ir3+. Electronic structure calculations on Ir2Sn3Se3 show a single, spherical, non-spin-orbit split valence band, and suggest that Ir2Sn3Se3 is topologically non-trivial under tensile strain, due to inversion of Ir-d and Se-p states.

Investigation Into the mechanism of action of disodium cromoglycate in pre-clinical models of asthma
Creators: name: Chen, Xue

description: Asthma is a disease with increasing global prevalence and patients typically suffer from symptoms such as wheezing, breathlessness, chest tightness and cough. Although in most cases asthma can be well controlled with current treatments, there remains an unmet need as patients do not always comply with therapies, and some remain unresponsive to treatment. In allergic asthma, exposure to allergen can lead to episodes of bronchoconstriction known as the late asthmatic response (LAR), a characteristic feature of asthma which has been shown to involve the activation of airway sensory nerves in a preclinical model. In asthmatics, DiSodium Cromoglycate (DSCG) is known to modulate the LAR but its use is limited because of its short duration of action seen evidenced by its pharmacokinetic profile. Although a safe and effective drug, the mechanism of action of DSCG remains unclear. The aim of this thesis is to investigate the mechanism with the possibility to develop a novel therapy with an improved PK profile and thus be a more useful treatment. Using a pre-clinical Brown Norway (BN) rat model of the LAR, it was established that both DSCG and a TRPA1 inhibitor can attenuate the LAR, suggesting an association between DSCG and TRPA1 on airway sensory nerves. This was confirmed by using an in vitro model of vagal sensory nerve activation, an in vitro model of airway specific neuron activation, in vivo sensory nerve recordings and an in vivo cough model, which all showed that DSCG can attenuate TRPA1 induced activation of airway sensory nerves. While investigating the mechanism by which DSCG inhibits airway sensory nerves, two distinct mechanisms were uncovered which depended on how the channel was opened. The first was that DSCG inhibited TRPA1 activity on airway sensory nerves through agonising GPR35 receptors. Selective GPR35 agonists demonstrated a similar inhibitory effect as DSCG, and this was reversed with GPR35 antagonists. Investigations showed that GPR35 was only responsible for some of the activity of DSCG on sensory nerves (i.e. with acrolein as the trigger); some DSCG modulated TRPA1 triggers were independent of GPR35 (i.e. PGE2). The second mechanism appeared to be via the blockade of TRPV2 channel/signalling and subsequent reduction of NADPH oxidase activity. The work within my thesis has therefore uncovered the important role of GPR35, TRPV2 and NADPH oxidase activity in the mechanism of action of DSCG by using pre-clinical models. These findings help to explain the beneficial effects observed in the clinic and also highlight novel targets for drug discovery.
Influence of intrinsic decoherence on tripartite entanglement and bipartite fidelity of polar molecules in pendular states

description: An array of ultracold polar molecules trapped in an external electric field is regarded as a promising carrier of quantum information. Under the action of this field, molecules are compelled to undergo pendular oscillations by the Stark effect. Particular attention has been paid to the influence of intrinsic decoherence on the model of linear polar molecular pendular states, thereby we evaluate the tripartite entanglement with negativity, as well as fidelity of bipartite quantum systems for input and output signals using electric dipole moments of polar molecules as qubits. According to this study, we consider three typical initial states for both systems respectively, and investigate the temporal evolution with variable values of the external field intensity, the intrinsic decoherence factor and the dipole-dipole interaction. Thus we demonstrate the sound selection of these three main parameters to obtain the best entanglement degree and fidelity.

The AGN dusty torus as a clumpy two-phase medium: radiative transfer modeling with SKIRT

description: We modeled the AGN dusty torus as a clumpy two-phase medium, with high-density clumps embedded in a low-density interclump dust. To obtain spectral energy distributions and images of the torus at different wavelengths, we employed the 3D Monte Carlo radiative transfer code SKIRT. Apart from the grid of two-phase models, we calculated the corresponding sets of clumps-only models and models with a smooth dust distribution for comparison. We found that the most striking feature of the two-phase model is that it might offer a natural solution to the common issue reported in a number of papers -- the observed excess of the near-infrared emission.
