description: Isospin effect of the statistical emission fragments from the equilibrated source is investigated in the frame of statistical binary decay implemented into GEMINI code, isoscaling behavior is observed and the dependences of isoscaling parameters $α$ and $β$ on emission fragment size, source size, source isospin asymmetry and excitation energies are studied. Results show that $α$ and $β$ neither depends on light fragment size nor on source size. A good linear dependence of $α$ and $β$ on the inverse of temperature $T$ is manifested and the relationship of $α=4C_{sym}[(Z_{s}/A_{s})_{1}^{2}-(Z_{s}/A_{s})_{2}^{2}]/T$ and $β=4C_{sym}[(N_{s}/A_{s})_{1}^{2}-(N_{s}/A_{s})_{2}^{2}]/T$ from different isospin asymmetry sources are satisfied. The symmetry energy coefficient $C_{sym}$ extracted from simulation results is $\sim$ 23 MeV which includes both the volume and surface term contributions, of which the surface effect seems to play a significant role in the symmetry energy.

description: CONTEXT: [ABRIDGED]. For the Milky Way bulge, there are currently essentially no measurements of carbon in un-evolved stars, hampering our abilities to properly compare Galactic chemical evolution models to observational data for this still enigmatic stellar population. AIMS: We aim to determine carbon abundances for our sample of 91 microlensed bulge dwarf and subgiant stars. Together with new determinations for oxygen this forms the first statistically significant sample of bulge stars that have C and O abundances measured, and for which the C abundances have not been altered by the nuclear burning processes internal to the stars. METHODS: The analysis is based on high-resolution spectra for a sample of 91 dwarf and subgiant stars that were obtained during microlensing events when the brightnesses of the stars were highly magnified. Carbon abundances were determined through spectral line synthesis of five CI lines around 9100 A, and oxygen abundances using the three OI lines at about 7770 A. [ABRIDGED] RESULTS: Carbon abundances was possible to determine for 70 of the 91 stars in the sample and oxygen abundances for 88 of the 91 stars in the sample. The [C/Fe] ratio evolves essentially in lockstep with [Fe/H], centred around solar values at all [Fe/H]. The [O/Fe]-[Fe/H] trend has an appearance very similar to that observed for other alpha-elements in the bulge, [ABRIDGED]. When dividing the bulge sample into two sub-groups, one younger than 8 Gyr and one older than 8 Gyr, the stars in the two groups follow exactly the elemental abundance trends defined by the solar neighbourhood thin and thick disks, respectively. Comparisons with recent models of Galactic chemical evolution in the [C/O]-[O/H] plane shows that the models that best match the data are the ones that have been calculated with the Galactic thin and thick disks in mind.

description: The spectral decomposition of regular sl_2-invariant R-matrices R(lambda) is studied by means of the method of reduction of the Yang-Baxter equation onto subspaces of a given spin. Restrictions on the possible structure of several highest coefficients in the spectral decomposition are derived. The origin and structure of the exceptional solution in the case of spin s=3 are explained. Analogous analysis is performed for constant R--matrices. In particular, it is shown that the permutation matrix P is a ``rigid'' solution.

An argument for the teaching of moral habits
Creators: name: Carroll, Christopher Joseph
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis an argument is presented that defends the inclusion of the teaching of moral habits in a program of moral education. The assertion is made that certain moral habits can be taught, as opposed to inculcated, because they are within the range of rationality. The argument is developed first by a defense of the possibility of knowledge and by extension moral knowledge. Differing views of moral education are then presented and the conclusion reached that rational deliberation is defensible, involving rational engagement with students concerning concepts relevant to ethics. The argument is made that if certain habits, including moral habits, fall within the range of the concept "rationality", and if the appropriate method of teaching moral education involves rationality, then the teaching of moral habits is possible and defensible. In order to support the notion that certain habits are within the range of the rational, the alleged "paradox" of moral education is analyzed, rejected and the assertion made that certain habits seems to be "infused" with reason. An analysis of "habit" follows and the assertion made that certain habits seem to fall within the range of rationality. The concept, "rationality", is then analyzed with the intention of showing that certain habits do fall within its range. The relationship of rationality to objectivity and truth are discussed to provided substance to the assertion that a body of moral knowledge does exist and can be taught. The last chapter concludes that certain moral habits fall within the range of the rational and can be included in a program of moral education. The thesis is conceptual in nature, with the purpose of defending the notion of the inclusion of moral habits in a program of moral education. Little discussion, therefore, is put forward concerning specific habits to be taught.
Corona and XUV emission modelling of the Sun and Sun-like stars

description: The X-ray and extreme-ultraviolet (EUV) emissions from the low-mass stars significantly affect the evolution of the planetary atmosphere. However, it is, observationally difficult to constrain the stellar high-energy emission because of the strong interstellar extinction of EUV photons. In this study, we simulate the XUV (X-ray+EUV) emission from the Sun-like stars by extending the solar coronal heating model that self-consistently solves, with sufficiently high resolution, the surface-to-coronal energy transport, turbulent coronal heating, and coronal thermal response by conduction and radiation. The simulations are performed with a range of loop lengths and magnetic filling factors at the stellar surface. With the solar parameters, the model reproduces the observed solar XUV spectrum below the Lyman edge, thus validating its capability of predicting the XUV spectra of other Sun-like stars. The model also reproduces the observed nearly-linear relation between the unsigned magnetic flux and the X-ray luminosity. From the simulation runs with various loop lengths and filling factors, we also find a scaling relation, namely $\log L_{\rm EUV} = 9.93 + 0.67 \log L_{\rm X}$, where $L_{\rm EUV}$ and $L_{\rm X}$ are the luminosity in the EUV and X-ray range, respectively, in cgs. By assuming a power-law relation between the Rossby number and the magnetic filling factor, we reproduce the renowned relation between the Rossby number and the X-ray luminosity. We also propose an analytical description of the energy injected into the corona, which, in combination with the conventional Rosner-Tucker-Vaiana scaling law, semi-analytically explains the simulation results. This study refines the concepts of solar and stellar coronal heating and derives a theoretical relation for estimating the hidden stellar EUV luminosity from X-ray observations.

description: In a Type II superconductor, the vortex core behaves like a normal metal. Consequently, the single-particle density of states in the vortex core of a conventional Type II superconductor remains either flat or (for very clean single crystals) exhibits a peak at zero bias due to the formation of Caroli-de Gennes-Matricon bound state inside the core. Here we report an unusual observation from scanning tunneling spectroscopy measurements in a weakly pinned thin film of the conventional s-wave superconductor a-MoGe, namely, that a soft gap in the local density of states continues to exist even at the center of the vortex core. We ascribe this observation to rapid fluctuation of vortices about their mean position that blurs the boundary between the gapless normal core and the gapped superconducting region outside. Analyzing the data as a function of magnetic field we show that the variation of fluctuation amplitude as a function of magnetic field is consistent with quantum zero-point motion of vortices.

description: Density fitting (DF), also known as the resolution of the identity (RI), is a widely used technique in quantum chemical calculations with various types of atomic basis sets - Gaussian-type orbitals, Slater-type orbitals, as well as numerical atomic orbitals - to speed up density functional, Hartree-Fock, and post-Hartree-Fock calculations. Traditionally, custom auxiliary basis sets are hand-optimized for each orbital basis set; however, some automatic schemes have also been suggested. In this work, we propose a simple yet numerically stable automated scheme for forming auxiliary basis sets with the help of a pivoted Cholesky decomposition, which is applicable to any type of atomic basis function. We exemplify the scheme with proof-of-concept calculations with Gaussian basis sets and show that the proposed approach leads to negligible DF/RI errors in Hartree-Fock (HF) and second-order Møller-Plesset (MP2) total energies of the non-multireference part of the W4-17 test set when used with orbital basis sets of at least polarized triple-$ζ$ quality. The results are promising for future applications employing Slater-type orbitals or numerical atomic orbitals, as well as schemes based on the use of local fitting approaches. Global fitting approaches can also be used, in which case the high-angular-momentum functions produced by the present scheme can be truncated to minimize the computational cost.

description: We consider a neutral holographic plasma with dynamical electromagnetic interactions in a finite external magnetic field. The Coulomb interactions are introduced via mixed boundary conditions for the Maxwell gauge field. The collective modes at finite wave-vector are analyzed in detail and compared to the magneto-hydrodynamics results valid only at small magnetic fields. Surprisingly, at large magnetic field, we observe the appearance of two plasmon-like modes whose corresponding effective plasma frequency grows with the magnetic field and is not supported by any background charge density. Finally, we identify a mode collision which allows us to study the radius of convergence of the linearized hydrodynamics expansion as a function of the external magnetic field. We find that the radius of convergence in momentum space, related to the diffusive transverse electromagnetic mode, increases quadratically with the strength of the magnetic field.

description: It is widely known in quantum mechanics that solutions of the Schröinger equation (SE) for a linear potential are in one-to-one correspondence with the solutions of the free SE. The physical reason for this correspondence is Einstein's principle of equivalence. What is usually not so widely known is that solutions of the Schrödinger equation with harmonic potential can also be mapped to the solutions of the free Schrödinger equation. The physical understanding of this equivalence is not known as precisely as in the case of the equivalence principle. We present a geometric picture that will link both of the above equivalences with one constraint on the Eisenhart metric.

description: This thesis provides a theoretical approach to represent enriched versions of heterogeneous schemata for semi-structured data. Based on regular tree grammars, the presented model constitutes a format- and technology-independent concept for the integration of research data in the context of the arts and humanities. As a result of the abstraction from technological problems, fundamental semantic aspects have been highlighted, whose resolution depends on the explication of the background knowledge of domain experts. An integrative system based on the presented model is enabled to classify issues of data integration into technological and context-dependent components—allowing the differentiated realization of the data integration concept in terms of adaptions to identifiable access protocols and schema languages—implementable mainly by software engineers and models of schemata and mappings, which are continuously described and refined by scholars and research projects. The model presents various extension points, among which the association of labels to entries in controlled vocabularies or ontologies seems intuitive in order to further enhance the semantic richness of represented schemata and provide unifying views based on ontological relations.

description: The chemistry of the diffuse interstellar medium is driven by the combined influences of cosmic rays, ultraviolet (UV) radiation, and turbulence. Previously detected at the outer edges of photodissociation regions (PDRs) and formed from the reaction of C+ and OH, CO+ is the main chemical precursor of HCO+ and CO in a thermal, cosmic-ray, and UV-driven chemistry. Our aim was to test whether the thermal cosmic-ray and UV-driven chemistry is producing CO in diffuse interstellar molecular gas through the intermediate formation of CO+ We searched for CO+ absorption with the Atacama Large Millimeter Array (ALMA) toward two quasars with known Galactic foreground absorption from diffuse interstellar gas, J1717-3342 and J1744-3116, targeting the two strongest hyperfine components of the J=2-1 transition near 236 GHz. We could not detect CO+ but obtained sensitive upper limits toward both targets. The derived upper limits on the CO+ column densities represent about 4% of the HCO+ column densities. The corresponding upper limit on the CO+ abundance relative to H2 is <1.2 x 10^{-10}. The non-detection of CO+ confirms that HCO+ is mainly produced in the reaction between oxygen and carbon hydrides, CH2+ or CH3+ , induced by suprathermal processes, while CO+ and HOC+ result from reactions of C+ with OH and H2O. The densities required to form CO molecules at low extinction are consistent with this scheme.

description: We present a new combinatorial model for identifying regulatory modules in gene co-expression data using a decomposition into weighted cliques. To capture complex interaction effects, we generalize the previously-studied weighted edge clique partition problem. As a first step, we restrict ourselves to the noise-free setting, and show that the problem is fixed parameter tractable when parameterized by the number of modules (cliques). We present two new algorithms for finding these decompositions, using linear programming and integer partitioning to determine the clique weights. Further, we implement these algorithms in Python and test them on a biologically-inspired synthetic corpus generated using real-world data from transcription factors and a latent variable analysis of co-expression in varying cell types.

description: We derive simple relations which express 2D light front force distributions in terms of 3D Breit frame pressure and shear force distributions. Mathematically the relations correspond to invertible Abel transformation and they establish one-to-one mathematical equivalence of 3D Breit frame force distributions and 2D light front ones. Any knowledge (model calculation, experimental measurement, etc.) about pressure and shear force distributions in Breit frame can be unambiguously transformed into light front force distributions with the help of Abel transformation. It is important that the transformation ensures 2D stability conditions if the 3D stability conditions are satisfied. As an illustration of how the relations work, we calculated the light front force distributions for a large nucleus as a liquid drop, and for large $N_c$ nucleon as a chiral soliton.

description: The exceptional combination of strength and ductility in multi-component alloys is often attributed to the interaction of dislocations with the various solute atoms in the alloy. To study these effects on the mechanical properties of such alloys there is a need to develop a modeling framework capable of quantifying the effect of these solutes on the evolution of dislocation networks. Large scale three-dimensional (3D) Discrete dislocation dynamics (DDD) simulations can provide access to such studies but to date no relevant approaches are available that aim for a complete representation of real alloys with arbitrary chemical compositions. Here, we introduce a formulation of dislocation interaction with substitutional solute atoms in fcc alloys in 3D DDD simulations that accounts for solute strengthening induced by atomic misfit as well as fluctuations in the cross-slip activation energy. Using this model, we show that local fluctuations in the chemical composition of various CrFeCoNi-based multi-principal element alloys (MPEA) lead to sluggish dislocation motion, frequent cross-slip and alignment of dislocations with solute aggregation features, explaining experimental observations related to mechanical behavior and dislocation activity. It is also demonstrated, that this behavior observed for certain MPEAs cannot be reproduced by assuming a perfect solid solution. The developed method also provides a basis for further investigations of dislocation plasticity in any real arbitrary fcc alloy with substitutional solutes.

description: We investigate the spin Seebeck effect and spin pumping in a junction between a ferromagnetic insulator and a magnetic impurity deposited on a normal metal. By the numerical renormalization group calculation, we show that spin current is enhanced by the Kondo effect. This spin current is suppressed by increase of the temperature or the magnetic field which is comparable with the Kondo temperature. Our results indicate that spin transport can be a direct probe of spin excitation in strongly correlated systems.

CONTRIBUTION OF EXCLOSURE FOR ENVIRONMENTAL CONSERVATION AND COMMUNITY LIVELIHOODS IN THE CENTRAL RIFT VALLEY AREA OF ETHIOPIA
Creators: name: Getachew Alemu Tayachew
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background: Exclosures are among degraded land rehabilitation strategies which are practiced in Ethiopia. However, due to lack of environmental and socio-economical virtues most exclosure are attributed negatively by local people and hence their sustainability left at risk.A study was carried out on two selected kebeles to investigate the effectiveness of exclosure in achieving the goal of environmental conservation and improving community livelihood strategy. Stratified random sampling was employed for the selection of sample households in two kebeles and they were surveyed using semi-structured questionnaires. Additionally, focus group discussions and key informant interviews were also administered. In all, a total of 96 households (70 non-participants and 26 participants) were interviewed. Data were presented in descriptive statistics. Results:The study showed that the majority of the local communities living next to exclosure were dependent on subsistence farming system mainly crop cultivation and animal rearing, but a few were participated in exclosure activities as a means of their livelihood strategy. Conversely, a majority of the household heads (66%) had a wish to participate in exclosure developmental activities. Conclusion:To ensure the sustainability of exclosure local community’s participation and beneficiary involvement is mandated in almost all exclosure activities but it has not been proved very significant in practice. Therefore, rehabilitating of degraded areas by exclosure can be success through greater participation and involvement of the local communities, and it becoming environmental soundness, economic viability and social acceptability

description: Good governance has the critical aim of promoting equity, increasing the quality of public service and economic growth. In this paper the scope of good governances are limited to basic elements of good governance like rule of law, participation, accountability, transparency, efficiency, responsiveness and effectiveness to assess the opportunities and challenges of good governance in court, finance and economic development and land administration offices in Tigray National Regional State specifically in Mekelle city administration. However, the opportunities and challenges of good governance in the identified areas still lack investigation. Therefore, the objective of this study is to examine the opportunities and challenges of good governance in Tigray National Regional State specifically in Mekelle city administration. The data collected via desk reviews, key informants and personal observation were critically analyzed. Consequently, the country’s constitution clearly indicates that functions of government at all levels shall be transparent and officials shall be accountable to the people unless officials shall be questioned. Further, the government is addressing the issues of good governance in its policies and plans. However, the collective action problems are occurred at multiple levels. Courts are also not fully equipped with the necessary number of skilled manpower at the some sub-cities are undermining good governance that effectively generate healthy services in the city. The communities in the city are also not fully informed what the city administration has been planned. Civil service reform program problems and corruption are also impeding the implementation of good governance. Service delivery on stated time and providing decision based on realistic evidence are hardly practiced in city. Lack of responsiveness, transparency, low interaction between stakeholders, lack of commitment and motivation of leaders and experts in city to facilitate the implementation of good governance are identified as the most impediments to good governance.

description: In the fragile and uncertain environment of arid and semi-arid area, camel plays a crucial role as a primary source of livelihood for pastoralists and agro-pastoralists. However, pastoral and agropastoralists in developing countries including Ethiopia are marginalized and generally not given due consideration in wider social-political analysis, although the camel and camel milk had been victim of neglect by policy, research and development under the livestock subsector. Therefore, this study is initiated with providing information on camel milk production and marketing though chain analysis and multiple linear regression model in agro-pastoral and pastoral area of Easter Ethiopia as such information would be useful to develop policy which is based on evidence.

description: Malnutrition is a general term for a medical condition caused by an improper or insufficient diet. Under nutrition is prevalent around the world. The objective of this study was to assess the prevalence of under nutrition and factors affecting nutritional status among children aged 6-59 months in Haramaya, eastern Ethiopia. The data were collected by using a well-structured pretested questionnaire. Anthropometric measurements of the children were taken to assess the nutritional status of the children. The prevalence of stunting, wasting and underweight were 36.07% [95% CI (0.314, 0.408)], 14.43% [95% CI (0.110, 0.179)] and 23.63% [95% CI (0.195, 0.278)], respectively. The current study showed that the prevalence of child under-nutrition is highly prevalent in Haramaya district. Community based nutrition program should be established; continuous nutrition supervision based on each nutritional status indicators and special attention to severely malnourished children is necessary to attempt the problem of malnutrition.

description: Chocolate spot causes substantial yield losses in various cropping seasons in Ethiopia and in many parts of the world wherever faba bean grows. Thus, integrated management of faba bean chocolate spot (Botrytis fabae Sard.) was studied using the moderately tolerant variety, ‘Degaga’ (R-878-3) and local cultivar during the 2012/13 main cropping season at Bekoji and Kulumsa Agricultural Research Centers in Arsi, Ethiopia. The experiment was laid out in a randomized complete block design in a factorial combination of two faba bean cultivars, two cropping systems (Degaga- and Local-barley intercropping in 1:1 ratio) and four spray intervals of fungicide (Chlorothalonil) applied at 7, 14 and 21 days after the onset of disease at a rate of 2.5kg a.i ha-1 and unsprayed control with three replications. Chocolate spot infection was more prevalent at Kulumsa with a significant (P<0.001) amount of disease observed as compared with Bekoji (P < 0.05). Applications of fungicide and cropping systems considerably reduced disease incidence, severity, area under the disease progress curve, disease progress rate, and increased faba bean grain yield and system productivity by a mean relative yield advantage of 31 and 39% at Bekoji and Kulumsa, respectively. Reduction in disease severity was observed in all fungicide sprayed intercropping systems and sole crops compared with the corresponding unsprayed intercrops and sole controls, with a general disease reduction from 35.4 to 23.4% at Bekoji and 68.9 to 40.9% at Kulumsa. However, considering the economics of fungicide application against the faba bean chocolate, maximum net profit was recorded from medium spray intervals (Local FB:BA 14-days) as compared with the other treatments at both locations. Faba bean-barley integrated management practice proved to help in reducing chocolate spot and increasing productivity and income especially under subsistence farming conditions in the country.

description: Objective: To assess factors associated with non-adherence to antiretroviral therapy among adults living with HIV/ AIDS in Arsi zone. Methods: This is a multiple facility-based cross-sectional study, where 306 adult aged over 18 years who were receiving antiretroviral therapy had interviewed using a structured questionnaire about their experience of taking antiretroviral therapy between June 1, 2015-June1, 2016. Additional data was extracted from each facilities record. Participants were defined as non-adherent if they missed at least one dose of their highly active antiretroviral therapy prescriptions within the last 30 days. Participants were also asked to indicate reasons for missing doses of highly active antiretroviral therapy. Descriptive analysis and Multivariable logistic regression model was used to determine predictors of non-adherence. The odds ratios in the binary logistic regression along with 95% confidence interval were used. Results: Overall, 306 clients responded; 35% were non-adherent. Seventy five (24.5%) and 214(69.9%) patients agreed and strongly agreed that the use of antiretroviral therapy is essential in their life. Thirty seven (12.1%) do not know whether drug resistance develop when antiretroviral therapy are missed or not. The reasons for missing doses include forgetting 71 (23.2%) and hiding from colleagues 90 (29.4%). Respondents who reported hiding from colleagues were found to be 2 times more likely to be non-adherent to antiretroviral therapy compared to respondents who had not reported hiding from colleagues (adjusted odds ratio = 2.02; 95% Confidence interval: 1.19-3.43). Conclusion: Prevalence of non-adherence to antiretroviral therapy is high. Some of the respondents do not know whether drug resistance develop when antiretroviral therapy are missed or not. Forgetfulness and hiding from colleague were the most common reason for missing doses. Hence, antiretroviral therapy counselors need to emphasis on memory aids. Creation of awareness on the risks of non-adherence is needed.

description: Motivated by recent experiments, we calculate particle emission from a Bose-Einstein condensate trapped in a single deep well of a one-dimensional lattice when the interaction strength is modulated. In addition to pair emission, which has been widely studied, we observe single-particle emission. Within linear response, we are able to write closed-form expressions for the single-particle emission rates and reduce the pair emission rates to one-dimensional integrals. The full nonlinear theory of single-particle emission is reduced to a single variable integrodifferential equation, which we numerically solve.

description: We report on the measurements of the total charge changing fragmentation cross sections in high-energy nucleus-nucleus collisions using Fe, Si and Pb incident ions. Several stacks of CR39 nuclear track detectors with different target combinations were exposed at normal incidence to high energy accelerator beams to integrated densities of about 2000 ions/cm^2. The nuclear track detector foils were chemically etched, and ion tracks were measured using an automatic image analyzer system. The cross section determination is based on the charge identification of beam ions and their fragments and on the reconstruction of their path through the stacks.

description: We prove and demonstrate here for the example of the large scale pixel detector of ATLAS that Serial Powering of pixel modules is a viable alternative and that has been devised and implemented for ATLAS pixel modules using dedicated on-chip voltage regulators and modified flex hybrids circuits. The equivalent of a pixel ladder consisting of six serially powered pixel modules with about 0.3Mpixels has been built and the performance with respect to noise and threshold stability and operation failures has been studied. We believe that Serial Powering in general will be necessary for future large scale tracking detectors.

description: Building upon prior work, we propose an alternative way to look at the pattern of spatial crime concentration and temporal stability of it. We first identify a high-crime cluster using the sample block groups in New York City by employing a k-means clustering method. We then examine the temporal stability of the high-crime cluster over time. We also longitudinally assess how our high-crime cluster classification is associated with the actual amount of crime while accounting for the measures of social and physical environments. We observed that about 6–12% of total areas are identified to be in the high-crime cluster. We also found that block groups identified to be high-crime cluster in one year are more likely to be that way in the next year. We hope future research may consider using data-driven approaches to expand understanding of spatial and temporal crime patterns.
