description: The relativistic heavy-ion collisions create both hot quark-gluon matter and strong magnetic fields, and provide an arena to study the interplay between quantum chromodynamics and quantum electrodynamics. In recent years, it has been shown that such an interplay can generate a number of interesting quantum phenomena in hadronic and quark-gluon matter. In this short review, we first discuss some properties of the magnetic fields in heavy-ion collisions and then give an overview of the magnetic field-induced novel quantum effects. In particular, we focus on the magnetic effect on the heavy flavor mesons, the heavy-quark transports, and the phenomena closely related to chiral anomaly.

description: We present a uniform analysis of the atmospheric escape rate of Neptune-like planets with estimated radius and mass (restricted to $M_{\rm p}<30\,M_{\oplus}$). For each planet we compute the restricted Jeans escape parameter, $Λ$, for a hydrogen atom evaluated at the planetary mass, radius, and equilibrium temperature. Values of $Λ\lesssim20$ suggest extremely high mass-loss rates. We identify 27 planets (out of 167) that are simultaneously consistent with hydrogen-dominated atmospheres and are expected to exhibit extreme mass-loss rates. We further estimate the mass-loss rates ($L_{\rm hy}$) of these planets with tailored atmospheric hydrodynamic models. We compare $L_{\rm hy}$ to the energy-limited (maximum-possible high-energy driven) mass-loss rates. We confirm that 25 planets (15\% of the sample) exhibit extremely high mass-loss rates ($L_{\rm hy}>0.1\,M_{\oplus}{\rm Gyr}^{-1}$), well in excess of the energy-limited mass-loss rates. This constitutes a contradiction, since the hydrogen envelopes cannot be retained given the high mass-loss rates. We hypothesize that these planets are not truly under such high mass-loss rates. Instead, either hydrodynamic models overestimate the mass-loss rates, transit-timing-variation measurements underestimate the planetary masses, optical transit observations overestimate the planetary radii (due to high-altitude clouds), or Neptunes have consistently higher albedos than Jupiter planets. We conclude that at least one of these established estimations/techniques is consistently producing biased values for Neptune planets. Such an important fraction of exoplanets with misinterpreted parameters can significantly bias our view of populations studies, like the observed mass--radius distribution of exoplanets for example.

description: In the present article, a double generally weighted moving average (DGWMA) control chart based on a three-parameter logarithmic transformation is proposed for monitoring the process variability, namely the S2-DGWMA chart. Monte-Carlo simulations are utilized in order to evaluate the run-length performance of the S2-DGWMA chart. In addition, a detailed comparative study is conducted to compare the performance of the S2-DGWMA chart with several well-known memory-type control charts in the literature. The comparisons indicate that the proposed one is more efficient in detecting small shifts, while it is more sensitive in identifying upward shifts in the process variability. A real data example is given to present the implementation of the new S2-DGWMA chart.

Creators: name: Tewodros, Daniel
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: This research project seeks to investigate factors affecting the performance of garment exporting industries in Ethiopia particularly the case of Addis Ababa. For the sake of achieving the objectives of this study, interview and questionnaires were analyzed using statistical analysis such as descriptive analyses. The information obtained through self-administered questionnaire from a sample of 16 operators and face-to-face interviews with respondents in the sector was conducted on industries under investigation. The respondent operators were selected using Purposive or judgmental sampling techniques. Besides, the interview questions were analyzed using descriptive narrations through concurrent triangulation strategy. The empirical study extracted major factors which seem to affect export performance of garment industries which include: unavailability of raw material, lack of capital, availability of skilled labor force, marketing problems, inadequate infrastructures, incapability of management, technological, poor institution and between industry relation and lacking government regulation and incentives. The findings further indicate that, the availability of raw material, skilled labor force, shortage of capital, absence of marketing personal and infrastructure being the most critical factors impeding garment industries engaged in export. Based on findings, recommendations to government bodies, to operators of garment industry sector and suggestions for other researchers are forwarded. Key words: garment, performance factors

description: Poor drought tolerance of European beech trees raised concerns in Europe. We hypothesized that beech could show an opposite physiological response to the same level of climatic drought with change in edaphic drought. We performed a combined analysis of δ13C and δ18O in tree rings to reveal retrospective temporal physiological responses of trees to drought. The edaphic drought was assessed by quantifying the capacity of soil to store water in plots (classified as “dry” and “less-dry”) near the drought limit of the species in three near-natural oak-beech ecotones in Germany and Switzerland. Neighbourhood competition was quantified. A climatic drought index was calculated from meteorological records and related to the δ13C and δ18O values of the trees. Trees from dry plots showed a higher response to drought and climatic dependency than less-dry plots. Neighbourhood competetion increased δ18O values significantly. Dual isotope analysis shows a tendency of greater stomatal resistance in dry plots and higher stomatal conductance in less-dry plots. We conclude that beech trees belonging to the same population under changing soil water availability can show different physiological responses under climatic drought stress. Our finding indicates the high plasticity of the beech trees to survive drought stress with changing site conditions.

description: A method to simulate anomalous fermion-boson interactions in Wtb vertex is presented with a minimal set of simulated samples of single top quark events at the LHC energies. In proposed method additional auxiliary vector fields corresponding to the Standard Model gauge fields are implemented for each type of the anomalous vertex structure. The method allows to simulate a manifestation of anomalous gauge couplings in two approaches used in experimental analyses either keeping only the linear order contributions in the anomalous couplings or keeping all contributions in numerators and denominators as appeared in matrix elements. All the single top quark production mechanisms, $t$-, $s$- and associative tW-channels are considered. The correctness of the proposed method is demonstrated.

Factors influencing effectiveness of internal audit in the Commercial Banking Sector the case of Commercial Bank of Ethiopia
Creators: name: Melkamsew, Kedami
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Generally, internal audit has become an essential management tool for achieving effective control in an organization. The main purpose of this study is to identify the factors that influence internal audit effectiveness in the Commercial Bank of Ethiopia (management support, management's perception of internal audit values, organizational independence of internal auditors, placement of adequate and competent internal audit staff, and the presence of approved internal audit charter) and to show the influences of the same on the effectiveness of internal audit activities. To address this purpose, the study required to answer the research question: To what extent these factors influence effectiveness of internal audit and which of them is the most important for internal audit effectiveness. The study adopted quantitative research methods and internal auditors of the CBE are the source for the required data to the researcher through the questionnaires administered and analyzed using SPSS. Census method was used to conduct the research. According to the research finding Organizational independence, the management support and management perceptions of internal Audit value highly affect the internal audit effectiveness. Whereas, availability of adequate and competent internal audit staff and the presence of approved internal audit charter were not significant impact on the effectiveness of internal audit. All of these five independent variables are making 85 % of the contributions for internal audit effectiveness. The Commercial Bank of Ethiopia should understand that the contributions of these variables were collectively significant to identify any noncompliance activities in their office and to add values for the IAE.

description: In this paper general dynamic equations describing the time evolution of isothermal quasi-incompressible multicomponent liquids are derived in the framework of the classical Ginzburg-Landau theory of first order phase transformations. Based on the fundamental {equations of continuum mechanics}, a general convection-diffusion dynamics is set up first for compressible liquids. The constitutive relations for the diffusion fluxes and the capillary stress are determined in the framework of gradient theories. {Next the general definition of incompressibility is given}, which is taken into account {in the derivation} by using the Lagrange multiplier method. To validate the theory, the dynamic equations are solved numerically for the quaternary quasi-incompressible Cahn-Hilliard system. It is demonstrated that variable density (i) has no effect on equilibrium (in case of a suitably constructed free energy functional), {and (ii) can} influence non-equilibrium pattern formation significantly.

description: Clear-cutting is an extensively used silvicultural method in the Nordic and Baltic countries, which strongly influences the site’s carbon (C) budget. In the current study, C budgets for a young silver birch stand chronosequence (2–8-year-old) were compiled using the C budgeting method. High variability of annual NEP between stands of similar ages occurred, as the C accumulation ability of young stands was site specific. Heterotrophic respiration (Rh), the main C efflux from the ecosystem, varied between (3.7 and 6.3 t C ha−1 yr−1) across all stands. Modelling of the annual NEP dynamics across the chronosequence revealed the C compensation point at a stand age of 6 years. The estimated cumulative C loss for the period when NEP was negative was almost 5 t C ha−1 and the amount of lost C could have been recaptured already in a 10-year-old stand. The C sink capacity of the studied sites depended mostly on the production of herbaceous plants until the production of the new tree generation became the main driver of ecosystem’s net primary production. Hence, site’s C accumulation capacity largely depends on the density and quality of the new forest regeneration.

description: We develop a generalized linear mixed model (GLMM) for bivariate count responses for statistically analyzing dragonfly population data from the Northern Netherlands. The populations of the threatened dragonfly species Aeshna viridis were counted in the years 2015–2018 at 17 different locations (ponds and ditches). Two different widely applied population size measures were used to quantify the population sizes, namely the number of found exoskeletons (‘exuviae’) and the number of spotted egg-laying females were counted. Since both measures (responses) led to many zero counts but also feature very large counts, our GLMM model builds on a zero-inflated bivariate geometric (ZIBGe) distribution, for which we show that it can be easily parameterized in terms of a correlation parameter and its two marginal medians. We model the medians with linear combinations of fixed (environmental covariates) and random (location-specific intercepts) effects. Modeling the medians yields a decreased sensitivity to overly large counts; in particular, in light of growing marginal zero inflation rates. Because of the relatively small sample size (n = 114) we follow a Bayesian modeling approach and use Metropolis-Hastings Markov Chain Monte Carlo (MCMC) simulations for generating posterior samples.

description: This exploratory research discusses natural ventilation in a traditional city through employing a computational method. The mechanism of airflow in traditional cities has not yet been sufficiently studied through experimental and computational methods. This paper reports work on simulating natural ventilation in traditional Bushehr City by means of computational models of airflow in the study zone under three design scenarios. Simulations show that the unstructured plan of the city is less likely to improve air circulation and velocity ratios. But the main corridor with a relatively wider width and straight direction is more likely to contribute to urban ventilation. Further use of evidence-based methods to test climate-responsive strategies of traditional cities may be helpful.
Assessment of Organizational Responses towards HIV/AIDS Pandemic (The case of BGI-Ethiopia and Ethiopian Telecommunication Corporation)
Creators: name: Gadissa, Demeke
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2008

description: This paper aims at the assessment of business responses towards HIV/AIDS pandemic by taking two case organizations in Addis Ababa (BGI-Ethiopia and Ethiopian Telecommunication Corporation) based on the responses of 124 employees (30 white collar and 94 blue collar workers). Data collected through a questionnaire and interview were analyzed using SPSS. The results revealed that, awareness level of workers on HIV/AIDS is good except few individuals who believe in the transmission of the virus because of working in the same office and eating in the same cafeteria with HIV positive employee. BGI-Ethiopia is using different alternatives means of HIV/AIDS awareness creation activities than ETC. Moreover, ETC's practice on ensuring non-discriminatory practice during employment, promotion, transfer, and training, is not satisfactory. Neither ETC nor BGI-Ethiopia is providing free home care and support services for employees who retired because of HIV/AIDS illness. Finally, mistrust, unwillingness to share information related to HIV/AIDS, poor health care infrastructure, low funding for HIV/AIDS project, and low commitment of higher officials were the challenge faced by the two organizations in response to HIV/AIDS. Based on the findings conclusions and recommendations were made.

description: Knowledge about the spatial variation of boreal forest soil carbon (C) stocks is limited, but crucial for establishing management practices that prevent losses of soil C. Here, we quantified the surface soil C stocks across small spatial scales, and aim to contribute to an improved understanding of the drivers involved in boreal forest soil C accumulation. Our study is based on C analyses of 192 soil cores, positioned and recorded systematically within a forest area of 11 ha. The study area is a south-central Norwegian boreal forest landscape, where the fire history for the past 650 years has been reconstructed. Soil C stocks ranged from 1.3 to 96.7 kg m−2 and were related to fire frequency, ecosystem productivity, vegetation attributes, and hydro-topography. Soil C stocks increased with soil nitrogen concentration, soil water content, Sphagnum- and litter-dominated forest floor vegetation, and proportion of silt in the mineral soil, and decreased with fire frequency in site 1, feathermoss- and lichen-dominated forest floor vegetation and increasing slope. Our results emphasize that boreal forest surface soil C stocks are highly variable in size across fine spatial scales, shaped by an interplay between historical forest fires, ecosystem productivity, forest floor vegetation, and hydro-topography.

description: Essential insights on the characterization and quality of a detectable biosphere are gained by analyzing the effects of its environmental parameters. We compiled environmental and biological properties of the Phanerozoic Eon from various published data sets and conducted a correlation analysis to assess variations in parameters relevant to the habitability of Earth's biosphere. We showed that environmental parameters such as oxygen, global average surface temperatures, runoff rates and carbon dioxide are interrelated and play a key role in the changes of biomass and biodiversity. We showed that there were several periods with a highly thriving biosphere, with one even surpassing present day biodiversity and biomass. Those periods were characterized by increased oxygen levels and global runoff rates, as well as moderate global average surface temperatures, as long as no large or rapid positive and/or negative temperature excursions occurred. High oxygen contents are diagnostic of biomass production by continental plant life. We find that exceptionally high oxygen levels can at least in one instance compensate for decreased relative humidities, providing an even more habitable environment compared to today. Beyond Earth, these results will help us to understand how environmental parameters affect biospheres on extrasolar planets and guide us in our search for extraterrestrial life.

description: We show that a heavy fermion superconductor UPt_3 is a topological Weyl superconductor with tunable Weyl nodes. Adopting a generic order parameter in the E_2u representation allowed by nonsymmorphic crystal symmetry, we clarify unusual gap structure and associated topological properties. The pair creation, pair annihilation, and coalescence of Weyl nodes are demonstrated in the time-reversal symmetry broken B-phase. At most 98 point nodes compatible with Blount's theorem give rise to line node-like behaviors in low-energy excitations, consistent with experimental results. We also show an arc node protected by the nonsymmorphic crystal symmetry on the Brillouin zone face.

The Impact of Drought on Livelihoods, Vulnerability and Coping Mechanisms: the Case of North Shoa Zone, Oromiya
Creators: name: Kebebe, Defferew
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Agriculture is one of the sectors most vulnerable to drought impact. The impact is even stronger in Africa, where agriculture is truly important for the daily subsistence, and where adaptive capacity is low. Therefore, it is crucial to increase the understandings of the concerned body and local community in the continent in general and in Ethiopia for future most likely drought impacts. This study uses the North Shoa Zone in Ethiopia, as a case study and examines the trends of drought and its impact on livelihood in the region. It also answers the questions who is more vulnerable and why, what are the local and institutional coping strategies and what are the constraints that aggravate vulnerability. The study uses personal observation, structured and semi-structured interview to gather information from local people, government officials and experts, and secondary data from published and unpublished sources, and systematically analyzes this material both using qualitative and quantitative analysis. The result shows that drought increases from time to time in the zone even if there is variation between and among years and it challenges the livelihood of the whole region. To cope up with the impacts, societies use savings, migration, credits, selling own assets (who own asset) and on-farm and off-farm diversification as strategy. The coping mechanisms provided by institutions is very weak and at its early stage in the zone. And the coping mechanisms available in the zone are not equally important and practiced and are insufficient to cope with drought impacts. Thought all households in the zone are vulnerable to the disaster, the problem is more acute on the poor, women, large size family, children, old and disabled. Vulnerability is further aggravated by the decline in the fertility of land, landlessness, unemployment, unavailability and inability of most farmers to afford agricultural inputs, fertilizer and selected variety of crop. The study suggests a relentless need to address these challenges both from short and long-term policy perspectiv

description: Since the discovery of neutrino oscillations many ideas have been put forward to explain the special features of the leptonic mixing and the differences with respect to the quark sector. In this talk I review some of these proposals, emphasizing especially their predictability. In the light of the new data, I first revisit fixed-point relations among mixing angles and phases. Then I briefly comment on radiative neutrino masses. Finally I discuss the role of flavour symmetries. Given the very many existing models I focus on two classes of models. On the one hand I illustrate the ability of models based on a generalization of the anarchy idea in reproducing the main features of both the quark and the lepton spectrum, also in a GUT framework. On the other hand I discuss less ambitious but more predictive models based on discrete flavour symmetries, centered on the properties of the leptonic mixing matrix.

description: Stimulated echo spectroscopy of nonselectively excitable I = 3/2 nuclei offers new perspectives for the investigation of ultraslow motions predominantly in inorganic solids and solid-like materials. Conditions for the generation of pure, quadrupole modulated multipolar spin orders and for the detection of two- and four-time correlation functions are discussed. The case of spins I > 3/2 is also briefly considered.

Prévention des infections
Compétences professionnelles

description: La toilette du résident est un soin qui mobilise un ensemble de compétences. L’observation de ce soin est l’occasion d’analyser les pratiques des professionnels concernant la prévention du risque infectieux des résidents. Notre équipe mobile d’hygiène (EMH) dédiée aux établissements d’hébergement des personnes âgées dépendantes (Ehpad) propose un audit des toilettes depuis 2021. Les objectifs sont de mesurer le respect des précautions standard mais aussi d’évaluer les moyens organisationnels permettant le respect des recommandations. Cette étude montre une moins bonne application des précautions standard chez les professionnels sans diplôme pour le respect des indications d’hygiène des mains, le port des EPI, l’évacuation du linge sale, le nettoyage-désinfection du matériel. La principale non-conformité liée à l’institution réside dans la sous-estimation du risque fécal avec une absence de moyens en locaux et matériels. Enfin, le port de tablier plastique pour tous les soins mouillant/souillant n’est pas encore considéré comme indispensable par certains professionnels mais aussi par certains acteurs clefs d’Ehpad. Cet audit observationnel permet de dresser un état des lieux des précautions standard afin de proposer des formations ou des organisations adaptées à chaque établissement. La restitution immédiate, dès la fin de l’observation, permet de sensibiliser le professionnel aux précautions standard. La restitution pédagogique globale, dans la même journée, proposée aux professionnels et aux acteurs clefs permet une discussion autour de propositions d’axes d’amélioration dans la prévention du risque infectieux. L’impulsion donnée par la direction et l’encadrement est essentielle pour faire vivre nos propositions et engager le changement de manière globale.
Relativistic dynamics of superfluid-superconducting mixtures in the presence of topological defects and an electromagnetic field with application to neutron stars

description: The relativistic dynamic equations are derived for a superfluid-superconducting mixture coupled to the electromagnetic field. For definiteness, and bearing in mind possible applications of our results to neutron stars, it is assumed that the mixture is composed of superfluid neutrons, superconducting protons, and normal electrons. Proton superconductivity of both I and II types is analysed, and possible presence of neutron and proton vortices (or magnetic domains in the case of type-I proton superconductivity) is allowed for. The derived equations neglect all dissipative effects except for the mutual friction dissipation and are valid for arbitrary temperatures (i.e. they do not imply that all nucleons are paired), which is especially important for magnetar conditions. It is demonstrated that these general equations can be substantially simplified for typical neutron stars, for which a kind of magnetohydrodynamic approximation is justified. Our results are compared to the nonrelativistic formulations existing in the literature and a number of discrepancies are found. In particular, it is shown that, generally, the electric displacement ${\pmb D}$ does not coincide with the electric field ${\pmb E}$, contrary to what is stated in the previous works. The relativistic framework developed here is easily extendable to account for more sophisticated microphysics models and it provides the necessary basis for realistic modelling of neutron stars.

description: We report a stable double optical spring effect in an optical cavity pumped with a single optical field that arises as a result of birefringence. One end of the cavity is formed by a multilayer Al$_{0.92}$Ga$_{0.08}$As/GaAs stack supported by a microfabricated cantilever, with a natural mode frequency of $274$ Hz. The optical spring shifts the resonance to $21$ kHz, corresponding to a suppression of low frequency vibrations by a factor of more than $10^{4}$. The stable nature of the optical trap allows the cavity to be operated without any external feedback and with only a single optical field incident.

description: This work presents an easy applicable method for estimating thermal conductivity of oxide ceramic samples in a high-temperature SOFC/SOEC system. An experimental investigation establishes a thermal conductivity map for various oxide ceramics in the temperature range of 700 - 900 °C. Material specific properties are determined using laser flash analysis, displacement measurement for density and differential scanning calorimetry for heat capacity. The total thermal conductivity, incorporating conduction and radiation, is assumed based on a linear relationship with temperature gradient. Deviations in measurements are attributed to increasing radiation effects. The method provides a rough estimation of thermal conductivity, with 8YSZ exhibiting good agreement with literature values and 10Sc1CeSZ showing a range of 2.3 (+0.32/-0.48) - 2.8 (+0.96/-1) W/mK.
Diphoton Signal of light pseudoscalar in NMSSM at the LHC

description: We explore the detection possibility of light pseudoscalar Higgs boson in the next-to-minimal supersymmetric Standard Model(NMSSM) at the LHC with the center of mass energy, $\sqrt{S}=13$ TeV. We focus on the parameter space which provides one of the Higgs boson as the SM-like with a mass of 125 GeV and some of the non-SM-like Higgs bosons can be light having suppressed couplings with fermions and gauge bosons due to their singlet nature. It is observed that for certain region of model parameter space, the singlet like light pseudoscalar can decay to di-photon($γγ$) channel with a substantial branching ratio. In this study, we consider this di-photon signal of light pseudoscalar Higgs boson producing it through the chargino-neutralino production and the subsequent decay of neutralino. We consider signal consisting of two photons plus missing energy along with a lepton from the chargino decay. Performing a detailed simulation of the signal and backgrounds including detector effects, we present results for a few benchmark points corresponding to the pseudoscalar Higgs boson mass in the range 60 -100 GeV. Our studies indicate that some of the benchmark points in the parameter space can be probed with a reasonable significance for 100 fb$^{-1}$ integrated luminosity. We also conclude that exploiting this channel it is possible to distinguish the NMSSM from the other supersymmetric models.

description: Corruption is a challenge to development. Scholars define corruption as abuse of public office for private benefit. Using this working definition, this study explores the main causes, the aggravating factors, work areas vulnerable to corruption and the means to combat corruption.Ethiopian Revenue and Customs Authority was taken as case study institution. Interviews were conducted with leaders and experts in the institution. From 2,905 population size in the selected four branches,one hundred fifty seven survey questionnaireswere administered to the staff of Ethiopian Revenue and Customs Authority by stratified sampling. The findings from this study confirm that corruption is increasing in extent and type (pity and grand corruptions). The perception of employee of the institution and the tax payers confirm the prevalence of corruption. Corruption has becomes a day to day tradition and considered as "normal"transaction, in terms of perception, including in ERCA office. From the findings of both primaryand secondary sources, there need to be enhancedholistic anti-corruption efforts and reforms, commitment of leaders and experts, building of strong institutions and corruption prevention and enforcement mechanisms at all levels. Creating an educating society starts from modeling students in ethics, inclusive development and coordinated approach in the staffs, leaders of the organization and the country at general Key Words: Challenges, consequences, corruption, perception, commitment, ethics, national integrity system, Ethiopian Revenue & Customs Authority, Federal Attorney General
