description: The $t_{2g}$ orbitals of an edge-shared transition-metal oxide with a honeycomb lattice structure form dispersionless electronic bands when only hopping mediated by the edge-sharing oxygens is accessible. This is due to the formation of isolated quasimolecular orbitals (QMOs) in each hexagon, introduced recently by Mazin et al. [Phys. Rev. Lett. 109, 197201 (2012)], which stabilizes a band insulating phase for $t_{2g}^5$ systems. However, with help of the exact diagonalization method to treat the electron kinetics and correlations on an equal footing, we find that the QMOs are fragile against not only the spin-orbit coupling (SOC) but also the Coulomb repulsion. We show that the electronic phase of $t_{2g}^5$ systems can vary from a quasimolecular band insulator to a relativistic $J_{\rm eff}=1/2$ Mott insulator with increasing the SOC as well as the Coulomb repulsion. The different electronic phases manifest themselves in electronic excitations observed in optical conductivity and resonant inelastic x-ray scattering. Based on our calculations, we assert that the currently known Ru$^{3+}$- and Ir$^{4+}$-based honeycomb systems are far from the quasimolecular band insulator but rather the relativistic Mott insulator.

In vitro starvation model for Assessing Phenotypic Drug Tolerance in Mycobacterium tuberculosis Lineages of Ethiopia
Creators: name: Ashagre, Wondimu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Background: Mycobacterium tuberculosis persist in the human host for decades and reactivation can occur at any point. It becomes dormant and phenotypically drug tolerant when exposed adverse conditions. Understanding of the signals and processes which allow the bacteria to achieve this feat could potentially be used as a baseline to design new types of drugs or modify old drug regimens for improved cure and avert development of drug resistance. Objective: To assess the level of phenotypic drug tolerance of Mycobacterium tuberculosis using in vitro nutrition starvation model. Methods: Three MTB lineages and one standard susceptible reference strain (H37Rv) were tested by different test methods at different time point from March to September 2017. All lineages tested to be sensitive to first-line anti-TB drugs. Log phase (highest colony count on week 3-4) culture from Lowenstein Jensen medium sub cultured to Middle-brook7H9 with 10% Oleic Acid Albumin Dextrose Catalase as a normal, Phosphate Buffer Solution (PBS) (PH 7.2) and Sterile Distilled water (SDW) as starvation media were used. Each week culture growth reading was performed, Acid Fast Stain (AFS) by Ziehl Neelson(ZN), Lipid Bodies (LB)by Sudan black stain and viability by Fluorescein DiAcitate (FDA) staining. On week 0, 3 and 6 drug susceptibility test was done by colorimetric MTT assay. Graph pad prism 6 and SPSS V20 used for data analysis. Results: A total of 576 experiments were performed using4 strains of Mycobacterium tuberculosis subcultured on SDW, PBS and 7H9 and. Of these, 324 microscopic tests using ZN(108)acid fastness, FDA(108) viability, and Sudan black stain(108) for lipid bodies, 108 culture growth reading done. After week 6 acid fastness, viability and culture growth decreased. 144 phenotypic DST done using MTT assay. A higher inhibitory drug concentration was required at the 6th week compared to the baseline and C50 (RMP=0.5;INH=0.1; STM=2.0 and for EMB=4.0), yet the proportion of lipid body containing bacilli increased continuously in all lineages. Conclusion: Our study showed that the mycobacteria lineages behaved similarly in all media systems and reached stationary phase at similar time. The increased drug concentration observed at the 6th week coincided with the decline in viable bacilli in all media systems, thus attributing this phenomena to lipid body accumulation alone was difficult.

description: Desho (Pennisetum glaucifolium) grass is one of the indigenous cultivated multipurpose perennial forage crops grown for animal feed and soil conservation practices in Ethiopia. This study was conducted to evaluate desho grass varieties for their morphological characteristics, dry matter yield performance, and nutritive value in the central highlands of Ethiopia. The study was conducted at Holetta Agricultural Research Center during the main cropping seasons of 2013 - 2017 under rain fed conditions. Four varieties of desho grass, viz. Areka (DZF # 590), Kulumsa (DZF # 592), Kindu Kosha-1 (DZF # 591), and Kindu Kosha-2 (DZF # 589) were planted in a randomized complete block design with three replications. Though the plant height of desho grass varieties was not significant (P>0.05) at each production year and combined over years, it significantly differed among the production years. The number of nodes per plant and leaf to stem ratio varied significantly while the internode length was not significant among desho grass varieties. The combined over years analysis indicated that the leaf and stem dry matter yields varied significantly (P<0.05) for desho grass varieties. Furthermore, the leaf and stem dry matter yields differed significantly among the production years. The total dry matter yield accumulated by desho grass varieties varied significantly and Areka (DZF # 590) variety accumulated the highest dry matter yield (23.8 t/ha) followed by Kulumsa (DZF # 592) variety (23.1 t/ha), while Kindu Kosha-1 (DZF # 591) accumulated the least (18.8 t/ha) dry matter yield. The first year of production produced the lowest dry matter yield while the accumulation of dry matter yield increased for consecutive production years but the yield declined in the last production year. The highest dry matter yield was accumulated in the 2016 production year and it had 19.8 and 4.3% advantages over the 2014 and 2015 production years, respectively. The crude protein yield and nutritive value among desho grass varieties was not significant. The result indicated that the crude protein yield of desho grass varieties ranged from 2.8 to 4.0 t/ha with a mean of 3.4 t/ha. Similarly, the crude protein content ranged from 10.7 to 12.5% with a mean of 11.7%. Generally, the varieties have comparable performances for measured traits in the study area. However, further study should be conducted over locations and years to select and recommend the best variety for the study area and to other similar agro-ecologies.

description: We investigate the possible existence of the bound state in the system of three bosons interacting with each other via zero-radius potentials in two dimensions (it can be atoms confined in two dimensions or tri-exciton states in heterostructures or dihalogenated materials). The bosons are classified in two species (a,b) such that a-a and b-b pairs repel each other and a-b attract each other, forming the two-particle bound state with binding energy $ε_b^{(2)}$ (such as bi-exciton). We developed an efficient routine based on the proper choice of basis for analytic and numerical calculations. For zero-angular momentum we found the energies of the three-particle bound states $ε^{(3)}_b$ for wide ranges of the scattering lengths, and found a universal curve of $ε^{(3)}_b/ε^{(2)}_b$ which depends only on the scattering lengths but not the microscopic details of the interactions, this is in contrast to the three-dimensional Efimov effect, where a non-universal three-body parameter is needed.

description: Recent experiments in hybrid-quantum systems facilitate the potential realization of one of the most fundamental interacting Hamiltonian-Reservoir system, namely, the single-site Bose-Hubbard model coupled to two reservoirs at different temperatures. Using Redfield equations in Born-Markov approximation, we compute non-equilibrium average particle number, energy and currents beyond linear response regime, both time-dynamics and steady state and investigate its dependence on various tunable parameters analytically. We find interesting scaling laws in high temperature regimes that are independent of choice of bath spectral functions. We also demonstrate that the system shows very interesting particle and energy current rectification properties which can be controlled via the relative strength of interaction and temperatures, as well as via the degree of asymmetry in system-bath coupling. Specifically, we find inversion of direction of thermal rectification as a function of the relative strength of the interaction strength and the temperatures. We also show that, in the limit of low-temperature and high interaction strength our results are consistent with the non-equilibrium spin-Boson model. Our results are experimentally relevant not only to hybrid quantum systems, but also in other areas such as molecular junctions.

description: We investigate a laser model for a resonant system of photons and ion cluster-solvated rotating water molecules in which ions in the cluster are identical and have very low, non-relativistic velocities and direction of motion parallel to a static electric field induced in a single direction. This model combines Dicke superradiation with wave-particle interaction. As the result, we find that the equations of motion of the system are expressed in terms of a conventional free electron laser system. This result leads to a mechanism for dynamical coherence, induced by collective instability in the wave-particle interaction.

description: The deconfinement transition and the hadronization mechanism at high energy are related to the quark-antiquark string breaking and the corresponding temperature depends on the string tension $σ$. In the Unruh scheme of hadron production it turns out $T = \sqrt{σ/2π}$, with $σ\simeq \E$, the vacuum energy density. In heavy ion collisions at lower energy, i.e. large baryonchemical potential, $μ_B$, the dynamics is dominated by Fermi statistics and baryon repulsion. However one can still consider $\E$ as the relevant physical scale and its evaluation as a function of the baryon density, in a nuclear matter approach, gives dynamical information on the $μ_B$ dependence of the hadronization temperature and on the value of the critical end point in the $T-μ_B$ plane.

description: The stress-strain anisotropy -including both elastic properties and dislocation distributions- of crystalline systems can be studied using a dislocation model proposed by Ungár and Borbély. However this model requires fundamental parameters (i.e., contrast factors), which take into account both the elastic properties and symmetry for each system. In this study, such contrast factors were calculated from first principles for cubic slip-systems through the evaluation of the distortion tensor in a dislocation-dependent coordinate set. Moreover, a straightforward expression for the computation of contrast factors is provided. Further analysis of the microstructural parameters was carried out using the modified Williamson-Hall method to characterize rock-salt materials.

Light sterile neutrinos from a late phase transition

description: Light sterile neutrinos represent a well-motivated extension of the 3-neutrino paradigm. However, the impressive agreement between standard cosmology and data casts doubts on their existence. Here we present a class of scenarios that robustly avoids this tension. In these models the sterile neutrinos are light, chiral states of a new sector interacting with the Standard Model via the right-handed neutrino portal and, crucially, active-sterile neutrino oscillations require a phase transition in the hidden sector. We explore the hidden-couplings/critical-temperature plane and identify regions where several sterile neutrinos can be accommodated. A late phase transition is usually preferred and may also ward off a potential threat posed by the formation of topologically stable defects.

description: Background: Type 2 diabetes is a major non-communicable disease with an increasing prevalence in Ethiopia and worldwide. About 2% of Ethiopians are reported to have type 2 diabetes, but this may be an underestimate, due to a paucity of studies on diabetes epidemiology in Ethiopia. Objective: Assessment of insulin resistance and dyslipidemia in type 2 diabetic patients attending diabetic clinic of the Tikur Anbessa Hospital, Addis Ababa. Methods: This study was carried out on 106 type 2 diabetic patients attending Tikur Anbessa Specialized Hospital Diabetic Clinic. Fasting blood glucose, serum lipid panels, serum insulin concentrations, Apo lipoprotein A-1 and Apo lipoprotein B were measured in diabetics who were taking oral medications. Patients taking insulin were excluded from the study. Insulin resistance was measured by calculating HOMA-IR for each patient. Blood pressure, body mass index (BMI), waist circumference and smoking status were also determined. Result: Most patients (80%) had poorly controlled fasting blood glucose (>126 mg/dL), and this was similar for males and females. Serum triglycerides were abnormally high in 58.7% of patients, LDL-cholesterol levels were elevated above 100 mg/dL in 50% of patients, and serum HDL-c levels were abnormally low in 76.9 % of patients.88.6% of the diabetic patients had showed significant insulin resistance (P<0.05), indicated by an elevated HOMA-IR index (>3.0). Two third of the diabetic patients showed normal blood pressure. Furthermore, sixteen of the 106 patients were cigarette smokers and smokers over 40 years old with diabetes had substantial cardiovascular risks as determined by their Framingham cardiovascular risk score. Conclusion: These results emphasize the need for improvedprograms for diabetes screening, prevention and care in Ethiopia. The biochemical and medical significance of the results are discussed.

description: Presently, deterioration of glass beads is a significant problem in conservation and restoration of beaded exhibits in museums. Glass corrosion affects nearly all kinds of beads but cloudy blue-green ones are more than others subjected to disastrous destruction. However, physical and chemical mechanisms of this phenomenon have not been understood thus far. This article presents results of a study of elemental and phase composition of glass of the blue-green beads of the 19th century obtained from exhibits kept in Russian museums. Using scanning electron microscopy, X-ray microanalysis and X-ray powder analysis we have detected and investigated Sb-rich microinclusions in the glass matrix of these beads and found them to be micro crystallites of KSbSiO$_5$. These crystallites were not detected in other kinds of beads which are much less subjected to corrosion than the blue-green ones and deteriorate in a different way. We belive that individual precipitates of KSbSiO$_5$ and especially their clusters play a major role in the blue-green bead deterioration giving rise to slow internal corrosion of the bead glass.

description: We consider a scenario where the inflaton decays to a hidden sector thermally decoupled from the visible Standard Model sector. A tiny portal coupling between the hidden and the visible sectors later heats the visible sector so that the Standard Model degrees of freedom come to dominate the energy density of the Universe before Big Bang Nucleosynthesis. We find that this scenario is viable, although obtaining the correct dark matter abundance and retaining successful Big Bang Nucleosynthesis is not obvious. We also show that the isocurvature perturbations constituted by a primordial Higgs condensate are not problematic for the viability of the scenario.

description: In the new precision era for cosmic ray astrophysics, theoretical predictions cannot content themselves with average trends, but need to correctly take into account intrinsic uncertainties. The space-time discreteness of the cosmic ray sources, together with a substantial ignorance of their precise epochs and locations (with the possible exception of the most recent and close ones) play an important role in this sense. We elaborate a statistical theory to deal with this problem, relating the composite probability P(Ψ) to obtain a flux Ψ at the Earth and the single-source probability p(ψ) to contribute with a flux ψ. The main difficulty arises from the fact that p(ψ) is a fat tail distribution, characterized by power-law or broken power-law behavior up to very large fluxes for which central limit theorem does not hold, and leading to well-known stable laws as opposed Gaussian. We find that relatively simple recipes provide a satisfactory description of the probability P(Ψ). We also find that a naive Gaussian fit to simulation results would underestimate the probability of very large fluxes, that is, several times above the average, while overestimating the probability of relatively milder excursions. At large energies, large flux fluctuations are prevented by causal considerations, while at low energies a partial knowledge on the recent and nearby population of sources plays an important role. A few proposal have been discussed in the literature to account for spectral breaks recently reported in cosmic ray data in terms of local contributions. We apply our newly developed theory to assess their probabilities, finding that they are relatively small.

description: Background Blood is one of the integral components of body constituents. Blood transfusion is important therapy during maternal bleeding, surgery and also a lifesaving procedure for anemic patients. Transfusion reaction and transfusion transmitted infections (TTI) are major problems associated with blood transfusion. TTI is ranging from 8% up to 43%. The burden of transfusion transmitted infections in developed countries decline from time to time but it is still a challenge of developing countries like Ethiopia due to lack of adequate volunteer donors, testing material, good infrastructure and well trend personnel because of resource constraints. In addition to that there are insufficient data on seropostivity of TTI among blood donors in our setting. Objective To assess the prevalence of transfusion transmitted infections among blood donors at Yirgalem hospital blood bank and Hawassa blood bank center, Sidama zone, SNNPRS Ethiopia. Methodology Institutional based cross-sectional study was conducted, convenient sampling techniques used to address 384 donors and blood collection was done from health volunteers and replacement donors from April-May, 2015 G.C at Yirgalem Hospital and Hawassa regional Blood bank. Data was coded, cleaned, entered and analyzed by using SPSS version 21.Proportion, odds ratio and p-value were used for analyses. P-value <0.05 considered as statistically significant. Result A total of 384 blood donors were screened and the overall prevalence of TTI was 28 (7.29%). The Seroprevalence of HIV, HBV, HCV, Syphilis and Malaria was 6(1.6%), 16(4.2%), 2(0.5%), 3(0.8%) 1(0.3%) respectively. Two out of 384(0.5%) had multiple infections. The combinations were HIV- HBV 1/384(0.26%) and HIV-HCV1/384(0.26%). The prevalence of HBV was 13/258(5.0%) and 3/126(2.4%) in male and female respectively, p=0.001. When see the age of donors, 15/331(4.5%) and 1/41(2.4%) in age group18-24 and 25-34 years respectively. The prevalence of HIV was 1/25(4.0%) and 5/359(1.4%) in urban and rural respectively, p=0.002 Conclusion and Recommendation The prevalence of TTI was 28(7.29%), the seroprevalence of HIV 6(1.6%), HBV 16(4.2%), HCV2 (0.5%), Syphilis 3(0.8%) and Malaria 1(0.3%). High prevalence of HBV, HCV and syphilis infection were found among family replacement blood donors when compared with voluntary blood donors. Students highly participated in voluntary blood donation program when compared with others. Creating awareness among the public is important to have voluntary donors and this helps to provide safe blood to blood transfusion and collection services.

description: We have demonstrated that a supersonic beam of methyl radicals (CH$_3$) in the ground rotational state of both $para$ and $ortho$ species has been slowed down to standstill with a magnetic molecular decelerator, and successfully captured spatially in an anti-Helmholtz magnetic trap for $>$ 1 s. The trapped CH$_3$ radicals have a mean translational temperature of about 200 mK with an estimated density of $>5.0\times10^7$ cm$^{-3}$. The methyl radical is an ideal system for the study of cold molecules not only because of its high reactivities at low temperatures, but also because further cooling below 1 mK is plausible via sympathetic cooling with ultracold atoms. The demonstrated trapping capability of methyl radicals opens up various possibilities for realizing ultracold ensembles of molecules towards Bose-Einstein condensation of polyatomic molecules and investigations of reactions governed by quantum statistics.

description: Explicit analytic expressions are derived for the effective-range function for the case when the interaction is represented by a sum of the short-range square-well and long-range Coulomb potentials. These expressions are then transformed into forms convenient for extrapolating to the negative-energy region and obtaining the information about bound-state properties. Alternative ways of extrapolation are discussed. Analytic properties of separate terms entering these expressions for the effective-range function and the partial-wave scattering amplitude are investigated.

description: Statistical models that analyse (pairwise) relations between variables encompass assumptions about the underlying mechanism that generated the associations in the observed data. In the present paper we demonstrate that three Ising model representations exist that, although each proposes a distinct theoretical explanation for the observed associations, are mathematically equivalent. This equivalence allows the researcher to interpret the results of one model in three different ways. We illustrate the ramifications of this by discussing concepts that are conceived as problematic in their traditional explanation, yet when interpreted in the context of another explanation make immediate sense.

Evaluation of Phlebotomy Services in Clinical Laboratory Setting in Addis Ababa Public
Creators: name: Liknaw, Wondimeneh
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Background: Phlebotomy being a critical part of the pre analytical phase of laboratory testing is the most neglected procedure in health care. About 70% of quality of test is affected during phlebotomy and other pre analytical services. However, little is known about the practice of phlebotomy services in developing countries like Ethiopia. Objectives: To assess the practice of phlebotomists and to identify the major sources of errors during venous blood collection in public hospitals in Addis Ababa. Methodology: Hospital based, cross sectional study was conducted from April 15 to May 10, 2014. The study followed 40 phlebotomists while each of them were collecting 5 different venous blood collections (giving a total of 200 phlebotomies). Well structured questionnaires and checklists were used to collect data. Data was entred on EPI-Data version 3.1and statistical analysis was performed with SPSS version 20. Descriptive statistics were employed and Chi square test was used for compairing major errors observed. Result: Almost all laboratory phlebotomy sites had no SOPs available in collection sites and most of collection sites were not well ventilated. The major errors identified were use of single glove for more than one client 139 of 200 (69.5%), inappropreate cleaning practice of vein puncture sites 180 of 200 (90%), collecting blood before the disinfectant alcohol is air dried 139 of 200 (69.5%), incorrect tube collection sequences 107 of 200 (53.5%), unnecessarly applying of tourniquets after blood started flowing in to the collection tubes and syringes 170 of 200 (85.0%) and applying tourniquets before locating and selecting approperate site for venous blood collection 175 of 200 (87.5%). Conclusion and Recommendation: - Many errors were identified in the phlebotomy practice during the observational study. As the quality of blood specimen influences patient result: emphasis should be given on phlebotomy training to improve the practices for phlebotomists and ensure safety as well as quality during blood collections for laboratory analysis.

Gap-bridging enhancement of modified Urca processes in nuclear matter

description: In nuclear matter at neutron-star densities and temperatures, Cooper pairing leads to the formation of a gap in the nucleon excitation spectra resulting in exponentially strong Boltzmann suppression of many transport coefficients. Previous calculations have shown evidence that density oscillations of sufficiently large amplitude can overcome this suppression for flavor-changing $β$ processes, via the mechanism of "gap bridging". We address the simplifications made in that initial work, and show that gap bridging can counteract Boltzmann suppression of neutrino emissivity for the realistic case of modified Urca processes in matter with $^3P_2$ neutron pairing.

Structure of the $\mathbf{Λ(1405)}$ from Hamiltonian effective field theory

description: The pole structure of the $Λ(1405)$ is examined by fitting the couplings of an underlying Hamiltonian effective field theory to cross sections of $K^- p$ scattering in the infinite-volume limit. Finite-volume spectra are then obtained from the theory, and compared to lattice QCD results for the mass of the $Λ(1405)$. Momentum-dependent, non-separable potentials motivated by the well-known Weinberg-Tomozawa terms are used, with SU(3) flavour symmetry broken in the couplings and masses. In addition, we examine the effect on the behaviour of the spectra from the inclusion of a bare triquark-like isospin-zero basis state. It is found that the cross sections are consistent with the experimental data with two complex poles for the $Λ(1405)$, regardless of whether a bare baryon basis state is introduced or not. However, it is apparent that the bare baryon is important for describing the results of lattice QCD at high pion masses.

Year: 2014

description: Background: Biosafety is an important practice in all laboratory settings especially in developing countries where standard operating procedures are lacking. There is only limited information about biosafety practices in government hospital laboratories in Addis Ababa. Objective: To assess the situation of biosafety practice and associated factors in clinical laboratory workers among government Hospitals in Addis Ababa, Ethiopia Method: Cross-sectional study design was conducted from March to May 2014; in all government Hospitals of Addis Ababa. A total of 290 laboratory professionals were participated about their biosafety practice and its associated factors using structured questionnaire to assess the structural and functional aspects of Biosafety Practice of laboratories. Data were coded and entered by Epi Info and Exported to SPSS V.20 for analysis. Bivariate and multivariate analysis were also used to identify factors that affect the outcome variable and to examine the effect of selected variables on laboratory personnel practice toward biosafety practice by using Odds Ratio (OR) with a 95% Confidence Interval. P- Value less than 0.05 were taken as statistically significant. Variables that were found with a statistically significant association (p<0.05) at bivariate logistic analysis were entered and analyzed by multiple logistic regression analysis. Results: - In this study a total of 290 laboratory professionals were involved. Out of those subjects the biosafety practice rates of protective barrier were 76.2%. The major factor for biosafety practice were practice of performing a written procedure for the clean-up of spills (AOR=2.31; CI 1.21-4.42), those who were practice of decontamination and wastes before disposal (AOR=2.69; CI 1.49-4.86) and those who got information in Participating a biosafety practice (AOR=5.07; CI 1.66-15.52) Conclusion: - This study revealed that there is an achievement of a minimum requirement of biosafety practice among studied laboratory personnel. Practice of performing clean-up of spills, practice of decontamination and wastes before disposal and information in participating a biosafety practice are a significant association with biosafety practice.
