description: En este trabajo se estudian las representaciones discursivas de masculinidades y feminidades que se tejen en la configuración y producción de los enunciados de la sección 'Columna de sexo' en la revista Soho. Para ello, se analizaron las marcas valorativas referidas a la mujer, al hombre y sus relaciones erótico-afectivas, desde las categorías de Afecto y Juicio propuestas por la teoría de la valoración. El corpus está constituido por 22 columnas escritas por mujeres, publicadas durante el periodo 2001-2005. Los resultados revelan una tendencia a reconocer que la mujer recibe una mayor aceptación que el hombre por parte de las autoras, en cuanto a la sexualidad y al entramado afectivo-erótico.

Year: 2018

description: The success of any business entity is not mainly influenced by its employees or any internal factors, but significantly determined by the level of customer satisfaction due to the products and services offered by that particular business. Fortunately, marketing mix, branding strategy and marketing relationship strategy can be used as each elements of it is designed to meet customer's needs and satisfaction. This study was conducted to examine the effect of marketing strategy on customer satisfaction at St. George brewery. A quantitative research of the data collection used and384 questionnaires is distributed and 330 usable questionnaires for response rate of 85.94% returned. Data was analyzed using descriptive, correlation and multiple regression analysis. The result of the study shows that among the six variables product, distribution, promotion and relation marketing strategy have positive significant impact on customer satisfaction while price and branding strategy don't. Following the findings, the study therefore recommended that the company should concentrate their attention on developing more and improved effective marketing strategies for retaining and sustaining their customers by satisfying their unlimited needs and wants

description: Uncertainty quantification plays an important role in biomedical engineering as measurement data is often unavailable and literature data shows a wide variability. Using state-of-the-art methods one encounters difficulties when the number of random inputs is large. This is the case, e.g., when using composite Cole-Cole equations to model random electrical properties. It is shown how the number of parameters can be significantly reduced by the Karhunen-Loeve expansion. The low-dimensional random model is used to quantify uncertainties in the axon activation during deep brain stimulation. Numerical results for a Medtronic 3387 electrode design are given.

description: The spatially discretized magnetic vector potential formulation of magnetoquasistatic field problems is transformed from an infinitely stiff differential algebraic equation system into a finitely stiff ordinary differential equation (ODE) system by application of a generalized Schur complement for nonconducting parts. The ODE can be integrated in time using explicit time integration schemes, e.g. the explicit Euler method. This requires the repeated evaluation of a pseudo-inverse of the discrete curl-curl matrix in nonconducting material by the preconditioned conjugate gradient (PCG) method which forms a multiple right-hand side problem. The subspace projection extrapolation method and proper orthogonal decomposition are compared for the computation of suitable start vectors in each time step for the PCG method which reduce the number of iterations and the overall computational costs.

description: During the Green Space Logistics and furthermore during the REACT projects, the consortium allocated time to literature review, interviews of experts and industrial partners, and tests to apply simplified, space-specific Life Cycle Assessment (LCA) to concrete cases. This helped to understand the current state-of-the-art and state-of-affairs in terms of assessment of the environmental impacts and ecodesign in the space sector.

Thanks to these efforts, knowledge gaps have been identified. Those cannot be filled within the scope of the ongoing project. Either because they require different expertise, or because the timescale or resources needed to research them do not correspond. Ongoing efforts, and potential projects to fill those gaps are listed and explained in this document.

"This document is open to public to provide recommendations to the scientific community to improve the understanding of environmental impact of launch vehicle." The announcement of opportunity can then be used, together with other sources, to justify new funding and projects which will contribute to the improvement of the knowledge to assess environmental impacts of space missions across Europe.
Multipole moments of a charged rotating disc of dust in general relativity

description: The gravitational and electromagnetic multipole moments of the charged rotating disc of dust, which is an axisymmetric, stationary solution of the Einstein-Maxwell equations in terms of a post-Newtonian expansion, are calculated and discussed. It turns out that the individual mass, angular momentum, electric and magnetic moments are ordered in the sense that higher moments have a lower absolute value. There is an interesting conjecture stating that the absolute values of all higher multipole moments of a uniformly rotating perfect fluid body are always greater than those of the corresponding Kerr spacetime, which we generalize to include charged bodies. We find that for the charged rotating disc of dust the conjecture holds (within the limits of accuracy of the post-Newtonian expansion).

Quasiclassical theory of magnetoelectric effects in superconducting heterostructures in the presence of the spin-orbit coupling

subject: FOS: Physical sciences

description: The quasiclassical theory in terms of equations for the Green's functions (Eilenberger equations) is generalized in order to allow for quantitative description of the magneto-electric effects and proximity-induced triplet correlations in the presence of spin-orbit coupling in hybrid superconducting systems. The formalism is valid under the condition that the spin-orbit coupling is weak with respect to the Fermi energy, but exceeds the superconducting energy scale considerably. On the basis of the derived formalism it is shown that the triplet correlations in the spin-orbit coupled normal metal can be induced by proximity to a singlet superconductor without any exchange or external magnetic field. They contain an odd-frequency even-momentum component, which is stable against disorder. The value of the proximity-induced triplet correlations is of the order of $Δ_{so}/\varepsilon_F$, that is absent in the framework of the standard quasiclassical approximation, but can be described by our theory. The spin polarization, induced by the Josephson current flowing through the superconductor/Rashba metal/superconductor junction, is also calculated.

description: Assessments of the quality of democracy focus on deviations from the rule of law and decreasing levels of political participation, but do not adequately explore the mechanisms through which the quality of democracy decreases. Populism is such a mechanism, used by populist leaders, after they ascent to power. Populism is combined with clientelism and corruption to form means of political domination in democratic regimes which are backpedalling or backsliding. Examples are three recently consolidated democratic regimes of Western Balkans. The governments of Aleksandar Vucic in Serbia, Nikola Gruevski in FYR Macedonia and Milo Djukanovic in Montenegro purposefully use populism, clientelism and corruption. Although not present in all back-sliding democracies, populism, clientelism and corruption are associated with backsliding from recently consolidated democracies and deterioration of the quality of democracy.

Nonlinear saturation of resistive tearing modes in a cylindrical tokamak with and without solving the dynamics
Creators: name: Loizu, J.

Publisher: name: arXiv
Year: 2023
Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: We show that the saturation of resistive tearing modes in a cylindrical tokamak, as well as the corresponding island width, can be directly calculated with an MHD equilibrium code without solving the dynamics and without considering resistivity. The results are compared to initial value resistive MHD simulations and to an analytical nonlinear theory. For small enough islands, the agreement is remarkable. For sufficiently large islands, the equilibrium calculations, which assume a flat current profile inside the island, overestimate the saturation amplitude. On the other hand, excellent agreement between nonlinear resistive MHD simulations and nonlinear theory is observed for all the considered tearing unstable equilibria.

description: We study the formation and the evaporation of a spherically symmetric black hole in conformal gravity. From the collapse of a spherically symmetric thin shell of radiation, we find a singularity-free non-rotating black hole. This black hole has the same Hawking temperature as a Schwarzschild black hole with the same mass, and it completely evaporates either in a finite or in an infinite time, depending on the ensemble. We consider the analysis both in the canonical and in the micro-canonical statistical ensembles. Last, we discuss the corresponding Penrose diagram of this physical process.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Due to the high cost of surfactant production caused by petrochemical feed stocks, considerable attention has been given to non-edible vegetable oils as an alternative source of feedstock. In this paper, a new non-edible oil derived surfactant based on Jatropha plant is synthesized. In this study the objective is synthesis and characterization of anionic surfactant from Jatropha Oil to substitute petroleum based anionic surfactant. The oil of jatropha was extracted by using Mechanical press and characterization of the oil has been done in order to make sure the oil is best fit for synthesizing anionic surfactant. Using transesterification process the extracted oil reacts with methanol by using catalyst sodium hydroxide to produce methyl ester. The molar ratio of H2SO4 to methyl ester, reaction temperature, reaction time and agitation speed on the sulfonation process of methyl ester produced was statistically investigated and important conditions are determined. A four-factor central composite design (CCD) combined with response surface modeling (RSM) and optimization was employed for maximizing the yield of sulfonated methyl ester based on 20 different experimental data. Analysis of variance (ANOVA) and other tests were used to test the significance of the independent variables and their interactions. Adequacy of the model was tested by the correlation between experimental and predicted response and enumeration of prediction errors. The predicted maximum active mater (68.3%) was found under the optimum conditions of the process variables (1:1 molar ratio of H2SO4 to methyl ester, 65oC of reaction temperature and 1.5 hours of reaction time) the result is close to the experimental value (69%) determined.

Thermodynamic uncertainty relations for systems with broken time reversal symmetry: the case of superconducting hybrid systems

Publisher: name: arXiv
Year: 2023
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We derive bounds to the thermodynamic uncertainty relations in the linear-response regime for steady-state transport in two-terminal systems when time reversal symmetry is broken. We find that such bounds are different for charge and heat currents and depend on the details of the system, through the Onsager coefficients, and on the ratio between applied voltage and temperature difference. As a function of such a ratio, the bounds can take any positive values. The bounds are then calculated for a hybrid coherent superconducting system using the scattering approach, and the concrete case of an Andreev interferometer is explored. Interestingly, we find that the bound on the charge current is always smaller than 2 when the system operates as a heat engine, while the bound on the heat current is always larger than 2 when the system operates as a refrigerator.

description: Explicit controlled-NOT gate sequences between two qubits of different types are presented in view of applications for large-scale quantum computation. Here, the building blocks for such composite systems are qubits based on the electrostatically confined electronic spin in semiconductor quantum dots. For each system the effective Hamiltonian models expressed by only exchange interactions between pair of electrons are exploited in two different geometrical configurations. A numerical genetic algorithm that takes into account the realistic physical parameters involved is adopted. Gate operations are addressed by modulating the tunneling barriers and the energy offsets between different couple of quantum dots. Gate infidelities are calculated considering limitations due to unideal control of gate sequence pulses, hyperfine interaction and charge noise.

To determine the sample from the total population of 520 employees, first, the target population was stratified in to four stratums and then to select respondents from each stratum simple random sampling technique was applied; having this, the researcher uses formula based-sample size determination. Basically, a total of 226 questionnaires were distributed to the sampled employee, among these 182 were returned. Thus, 182 returned questionnaires (i.e. representing 80.5%) % of response rate) are analyzed using statistical package for social science (SPSS version 20). In the analysis descriptive statistics, correlation analysis and; linear regression analysis was performed. The descriptive finding of the study shows that in NTE Share Company employees had low level satisfaction existing performance appraisal practice of criteria(factors). Employees of NTE Share Company have low level of work performance. The analysis of result indicated that there is no performance appraisal satisfaction in the Company and employees' work performance relationship that is weak or low level of the employees' work performance. The response about the effect of performance appraisal System on level employees' satisfaction with Distinctiveness the respondent to some extent was positive. And also Consistency and Consensus low level of satisfaction .the correlation analysis result also indicates employees' work performance of performance appraisal System had positive and significant (Very strong association) relationship with employees' work performance whereas the finding of linear regression analysis indicates that performance appraisal System had positively and significantly influence work performance. Therefore,. In doing so, human resource department should play a vital role in the overall process of performance appraisal System influence employees' work performance. Finally, it is forwarded that further research has to be done in more completed and comprehensive way. Keywords: Factors affecting of PAS and Effective PA elements, Employees work performance.

description: Three-dimensional topological Dirac semimetals have recently gained significant attention, since they possess exotic quantum states. When constructing Josephson junctions utilizing these materials as the weak link, the fractional ac Josephson effect emerges in the presence of a topological supercurrent contribution. We investigate the ac Josephson effect in a Dirac semimetal Cd$_3$As$_2$ nanowire using two complementary methods: by probing the radiation spectrum and by measuring Shapiro patterns. With both techniques, we find that conventional supercurrent dominates at all investigated doping levels and that any potentially present topological contribution falls below our detection threshold. The inclusion of thermal noise in a resistively and capacitively shunted junction (RCSJ) model allows us to reproduce the microwave characteristics of the junction. With this refinement, we explain how weak superconducting features can be masked and provide a framework to account for elevated electronic temperatures present in realistic experimental scenarios.

description: In this paper, we consider joint drift rate control and impulse control for a stochastic inventory system under long-run average cost criterion. Assuming the inventory level must be nonnegative, we prove that a $\{(0,q^{\star},Q^{\star},S^{\star}),\{μ^{\star}(x): x\in[0, S^{\star}]\}\}$ policy is an optimal joint control policy, where the impulse control follows the control band policy $(0,q^{\star},Q^{\star},S^{\star})$, that brings the inventory level up to $q^{\star}$ once it drops to $0$ and brings it down to $Q^{\star}$ once it rises to $S^{\star}$, and the drift rate only depends on the current inventory level and is given by function $μ^{\star}(x)$ for the inventory level $x\in[0,S^{\star}]$. The optimality of the $\{(0,q^{\star},Q^{\star},S^{\star}),\{μ^{\star}(x): x\in[0,S^{\star}]\}\}$ policy is proven by using a lower bound approach, in which a critical step is to prove the existence and uniqueness of optimal policy parameters. To prove the existence and uniqueness, we develop a novel analytical method to solve a free boundary problem consisting of an ordinary differential equation (ODE) and several free boundary conditions. Furthermore, we find that the optimal drift rate $μ^{\star}(x)$ is firstly increasing and then decreasing as $x$ increases from $0$ to $S^{\star}$ with a turnover point between $Q^{\star}$ and $S^{\star}$.

Fatigue crack growth in the threshold region

description: The fatigue behaviour of aerospace structural components is dominated by the time to grow from a small sub mm size flaw to a flaw of the order of a few mm. As such crack growth is dominated by the Region I growth of short cracks. Consequently management of the fleet requires that Region I short crack growth be both understood and predicted. Recent studies at the NASA Johnson Space Center have shown that the current ASTM testing standards can produce Region I da/dN versus K data that are a function of the test geometry and, as result, that similitude was not valid in Region I. As a result the NASA Johnson Space Center has abandoned these standards. Similar conclusions follow from recent Australian studies into cracking in 7050-T7451 aluminium alloy under variable amplitude loading. This research particularly focuses on the near threshold crack growth behaviour in 7050-T7451 aluminium Alloy, which is widely used in F/A-18 Hornet, the Super Hornet and the Joint Strike Fighter (F35). In order to understand the short crack growth behaviour, a fatigue test program in 7050-T7451 Aluminium Alloy specimens under repeated block loading was performed. The results show that the short crack growth rate (da/dN) versus K anomaly is due to forcing a relationship between them. It is also shown that this anomaly vanishes if crack growth is expressed using the Generalized Frost-Dugdale crack growth equation or the Hartman-Shijve crack growth equation. In order to investigate the effect of the stress concentration factor (Kt) on the crack growth rate, the growth of fatigue cracks from etched pits and machinery defects at a fastener hole under an operation RAAF load spectrum was analysed. The results of this study show that the Hartman-Schijve equation can be used to predict DSTO short crack growth tests data for both low and high Kt specimens. Crack growth under a representative combat and transport load spectrum was also studied. The characteristic stress intensity factor range Krms and the Effective Block Approach for analysing fatigue crack growth was conducted. Here it was found that the Krms effective block approach is a valid method for predicting crack growth under F-15 Eagle fighter aircraft and military transport spectra. The use of the fractal based crack growth equation was also evaluated. In this content it was found that fracture surfaces associated with the growth of cracks from small near micron initial defects can be treated as a fractal set and that crack growth conforms to a fractal crack growth equation. From this research, the growth of fatigue cracks from small pits, typically less than 20m, to long cracks, can be represented by the Generalized Frost-Dugdale crack growth equation and the Hartman-Schijve crack growth equation.

description: This research paper aimed mainly at studying the effect of fermentation on QPM-soybean blends with respect to the nutritional quality, antinutrient, proximate & micronutrient compositions, functional & physico-chemical properties, microbiological & sensory analysis. Seed varieties of QPM & soybean (BHQPY-545 & Afgat) were collected from Bako & Hawassa Agricultural Research Centres respectively. After sample preparation, the flour was formulated with QPM to soybean blend ratio of 82:18 using material balance method (protein-carbohydrate ratio). QPMsoybean blend flours were fermented for 24 & 48h by natural & controlled fermentations. Both unfermented and fermented samples were subjected to the analysis. The proximate analysis results before & after fermentation in (%) were 14.72, 17.43 for crude protein; 8.42, 10.2 for crude fat; 7.33, 4.49 for crude fiber; 66.63, 66.90 for total carbohydrates and 400.81Kcal./100g, 412.67Kcal./100g for calorific value. Significant differences (P<0.05) were observed between unfermented & fermented blends in proximate compositions, with specific increment of 15.5% for protein & 3% calorific value. Results of antinutrient content (tannin & phytate) in (mg/100g) were 21.95, BDL & 249.20, 155.75 with notable reduction. Micronutrient increment in (mg/100g) for P, Fe & Zn was 32.57 to 61.9; 3.98 to 7.20 & 2.61 to 4.21 respectively. Fermentation significantly (p<0.05) decreased the antinutrients which resulted in a significant (p<0.05) increase in micronutrients. Fermentation had a significant (p<0.05) increasing effect on pH, dispercebility and oil absorption whereas; decreasing effect on titratable acidity, viscosity; bulk density & water absorption. Microbiological result showed significant (p<0.05) reduction or elimination of undesirable coliform count & increment of LAB with increasing fermentation time. Fermentation process significantly (p<0.05) affected the product performance analysis. Therefore, gruel prepared from the fermented blend flour at 24h of fermentation and <250μm particle size was acceptable with higher scores of 7.80 for appearance, 7.54 for odor, 8.10 for taste, and 8.50 for overall acceptability, which is not significantly (p>0.05) different from the control. According to the result of the study, both types of fermentation comparably reduced or eliminated antinutrients and improved the nutritional quality of the weaning blend with preference for natural fermentation, which is inexpensive processing method that consumers especially low & medium income families can easily afford good quality product. Key words: Antinutrient, effect, fermentation, micronutrient, natural fermentation, proximate composition, QPM, soybean, Weaning food.
