description: Background: Bacterial meningitis remains a major cause of mortality and morbidity in neonatology and pediatrics patients in many countries of the world including Ethiopia. Information on prevalence of bacterial meningitis, susceptibility of the causative microorganism to rationalize treatment and associated risk factors is scare among pediatrics groups. Objective: To isolate bacteria's from CSF specimen, determine antimicrobial susceptibility pattern and to assess associated risk factors with special emphasis on Streptococcus pneumoniae among pediatrics suspected meningitis patients attending pediatrics clinic at Tikur Anbessa and Yekatit 12 specialized hospitals, Addis Ababa, Ethiopia. Methodology: A hospital based cross sectional study was conducted at Tikur Anbessa and Yekatit 12 specialized hospitals, from September, 2013 to January, 2014. A consecutive sampling technique was used. Three hundred eighty five pediatrics patients attending the hospital at pediatrics ward that were gave CSF samples for diagnostic purpose were enrolled in the study. Samples were taken from them and analyzed according to standard microbiological (culture) procedures, antimicrobial susceptibility pattern were determined using disc diffusion technique and serological (BinaxNOW streptococcus pneumoniae antigen test) procedure was also done. Datas were double entered with EPI INFO version 3.5.3 and analyzed using SPSS version 21 software. Binary logistic regression was used to identify the association between variables. Sensitivity, specificity, PPV and NPV were used to see the performance of the ICT. Result: Bacterial pathogens were isolated from 17 patients showing an isolation rate of 4.4%.Among these, 58.8% and 41.2% were gram negative and gram positive organisms respectively. The most commonly isolated bacteria were S.pneumoniae (35.3%), followed by Neisseria meningitidis (11.8%). Among all risk factors assessed, none of them were statistically significant with suspected meningitis cases (p>0.05). The antimicrobial sensitivity remained high for third generation cephalosporins for most of the isolates. The ICT increased the detection of pneumococcus over culture. Conclusion The prevalence of bacterial isolates in this study was 4.4%. Antigen detection (BinaxNOW S.pneumoniae test in our study) is a better adjuvant to culture. Frequency of single as well as multiple drug resistance was very high among the bacterial isolates. Area specific periodic evaluation of antimicrobial susceptibility test will be important

description: A one dimensional stochastic exclusion process with two species of particles, $+$ and $-$, is studied where density of each species can fluctuate but the total particle density is conserved. From the exact stationary state weights we show that, in the limiting case where density of negative particles vanishes, the system undergoes a phase separation transition where a macroscopic domain of vacancies form in front of a single surviving negative particle. We also show that the phase separated state is associated with a diverging correlation length for any density and the critical exponents characterizing the behaviour in this region are different from those at the transition line. The static and the dynamical critical exponents are obtained from the exact solution and numerical simulations, respectively.

description: Surface distributions of two level system (TLS) defects and magnetic vortices are limiting dissipation sources in superconducting quantum circuits. Arrays of flux-trapping holes are commonly used to eliminate loss due to magnetic vortices, but may increase dielectric TLS loss. We find that dielectric TLS loss increases by approximately 25% for resonators with a hole array beginning 2 $μ\text{m}$ from the resonator edge, while the dielectric loss added by holes further away was below measurement sensitivity. Other forms of loss were not affected by the holes. Additionally, we estimate the loss due to residual magnetic effects to be $9\times 10^{-10} /μ\text{T} $ for resonators patterned with flux-traps and operated in magnetic fields up to $5$ $μ\text{T}$. This is orders of magnitude below the total loss of the best superconducting coplanar waveguide resonators.

description: Abstract: Waray is a major language spoken in the Eastern Visayas region of the Philippines. In this paper I argue that genitive case undergoers in clauses describing semantically transitive situations are neither direct objects, nor oblique constituents. Rather their grammatical properties result from speakers’ choice to “de-perspectivize” an undergoer. Consequently, constructions that have been called “Actor Voice” in studies of other Philippine languages are in fact grammatically Intransitive. This observation has profound consequences for the conceptualization of voice and grammatical relations in Philippine languages.

description: Background: Correct diagnosis of malaria is crucial for proper treatment of patients and surveillance of the disease. However, there are various limiting factors including inadequate infrastructure and consumables. Furthermore, inappropriate perception and inadequate satisfaction of health service providers and users are suggested as significant challenges in the utilization and the quality of laboratory malaria diagnostic services in other African countries. Objective: To assess perceptions and satisfactions of patients and health professionals about malaria diagnostic service in Awi Zone, Amhara National Regional State, North West Ethiopia. Methods: Health facility based cross sectional study was conducted from November to December 2013. The patient sample size was determined by using single population proportion. Interview and self administered structured questionnaires were employed to collect information from laboratory personnel, clinicians and patients. Data were collected from 304 patients, 99 clinicians, 26 laboratory professionals and 11 key informants. Data was entered using Epi-Info 3.5.3, further analysis was done by SPSS version 20. Chi-square test was used to determine association between the main out come and associated factors. The strength of association between covariates and the main outcome was identified by using odds ratio in binary logistic regression, and also multiple logistic regression was utilized to crosscheck confounders for those associated variables. Values less than 0.05 and 95% CI were taken as significant level. Result: Overall 52.6% of patients, 50% of laboratory professionals, and 61.2% of clinicians were satisfied with malaria diagnostic service in their health facility laboratories. Ethnicity, residence, knowing malaria diagnosis after consulting clinician, and time period to receive malaria result were independent predictors for patient satisfaction (p< 0.05). Lack of benefit, training or professional development and insufficient duty payment besides unequal workload were some of the factors significantly affected lab professionals level of satisfaction (p<0.05). Request for laboratory malaria diagnosis on the basis of clinical signs and symptoms of patients and trust for malaria diagnostic result were important predictors for clinician satisfaction (p<0.05). Conclusion and Recommendation: Based on the finding, patients and health professionals level of satisfaction on malaria diagnosis service was in the range of 50% to 61.2%. Lab constraints were the main factors that mimic satisfaction for health professionals, and these in turn might cause negligence of professionals towards patients and prolonged waiting time that presented dissatisfaction for patients. Thus, the regional government should focus on those constraints that compromise the quality of malaria diagnostic service.

description: In single field slow-roll inflation, one expects that the spectral index $n_s -1$ is first order in slow-roll parameters. Similarly, its running $α_s = dn_s/d \log k$ and the running of the running $β_s = dα_s/d \log k$ are second and third order and therefore expected to be progressively smaller, and usually negative. Hence, such models of inflation are in considerable tension with a recent analysis hinting that $β_s$ may actually be positive, and larger than $α_s$. Motivated by this, in this work we ask the question of what kinds of inflationary models may be useful in achieving such a hierarchy of runnings, particularly focusing on two--field models of inflation in which the late-time transfer of power from isocurvature to curvature modes allows for a much more diverse range of phenomenology. We calculate the runnings due to this effect and briefly apply our results to assessing the feasibility of finding $|β_s| \gtrsim |α_s|$ in some specific models.

description: Non-linear phenomena in optically excited semiconductor structures are of high interest. We here develop a model capable of studying the dynamics of the photoexcited carriers, including Coulomb interaction on a Hartree-Fock level, on the same footing as the dynamics of the light field impinging on an arbitrary photonic structure. Applying this method to calculate the third harmonic generation in a semiconductor quantum well embedded in a Bragg mirror structure, we find that the power-law exponent of the intensity dependence of the third harmonic generation depends on the frequency of the exciting pulse. Off-resonant pulses follow the expected cubic dependence, while the exponent is smaller for resonant pulses due to saturation effects in the induced carrier density. Our study provides a detailed understanding of the carrier and light field dynamics during non-linear processes.

description: Background: H.pylori is a gram-negative bacterium found on the luminal surface of the gastric epithelium. At least 50% of the world's human population has H.pylori infection. Studies have shown an increased prevalence of this bacteria in people infected with HIV relied on the CD4 count level. Aim:To determine the burden H.pylori and its association with CD4 count among HIV infected individuals who attend the ART service in Kotebe Health Center, Yeka Sub City, Addis Ababa, Ethiopia. Methods:A cross sectional Study was conducted from October to November 2016 on 388HIV infected individuals at Kotebe Heath Center, Yeka Sub City Addis Ababa. Convenient sampling technique was employed to include study participants who met the inclusion criteria. CD4 count and hemoglobin level with demographic and other variables such as habit of drinking alcohol, habit of eating chat, habit of personal hygienic practice, and also direct stool microscopy examination was included in the study. Results:The prevalence of H.pylori infection among study subject was 54.8%, H.pylori infection among female participant was 51.8% (133/256) and among male participant was 60.6% (87/143) with X2 = 2.745a and P-Value 0.098. The prevalence of H.pylori infection in patient with CD4 count level less than 500 was 54.4% (131/141) and with CD4 count level greater than 500 was 55.1% (81/147).The prevalence of H.pylori was 67.1% (61/91) among HIV clients with people in the house hold greater than four. The prevalence of H.pylori infection among HIV clients those use tanker water, wheel water, pipe water was 50% (2/4), 25% (4/16) and 55.9% (226/401) respectively (X2= 6.114a P. value=0.047). Conclusion: There was no significant association between the prevalence of H.pylori and level of CD4 cell count. But there was significant association between number people in the house hold and type of water used for drinking. And there was no significant association between with socio demographic data like age, sex, marital status, educational level, stage of ART taking, habit for drinking of alcohol, smoking, eating of chat, and habit of hand washing, and pervious history of GIT.

description: Long coherence times are key to the performance of quantum bits (qubits). Here, we experimentally and theoretically show that the Hahn-echo coherence time (T2) of electron spins associated with divacancy defects in 4H-SiC reaches 1.3 ms, one of the longest T2 times of an electron spin in a naturally isotopic crystal. Using a first-principles microscopic quantum-bath model, we find that two factors determine the unusually robust coherence. First, in the presence of moderate magnetic fields (300 G and above), the 29Si and 13C paramagnetic nuclear spin baths are decoupled. In addition, because SiC is a binary crystal, homo-nuclear spin pairs are both diluted and forbidden from forming strongly coupled, nearest-neighbor spin pairs. Longer neighbor distances result in fewer nuclear spin flip-flops, a less fluctuating intra-crystalline magnetic environment, and thus a longer T2 time. Our results point to polyatomic crystals as promising hosts for coherent qubits in the solid state.

description: We study the intrinsic, disorder-induced decoherence of an isolated quantum system under its own dynamics. Specifically, we investigate the characteristic time scale (i.e., the decoherence time) associated with an interacting many-body system losing the memory of its initial state. To characterize the erasure of the initial state memory, we define a time scale, the intrinsic decoherence time, by thresholding the gradual decay of the disorder-averaged return probability. We demonstrate the system-size independence of the intrinsic decoherence time in different models, and we study its dependence on the disorder strength. We find that the intrinsic decoherence time increases monotonically as the disorder strength increases in accordance with the relaxation of locally measurable quantities. We investigate several interacting spin (e.g., Ising and Heisenberg) and fermion (e.g., Anderson and Aubry-André) models to obtain the intrinsic decoherence time as a function of disorder and interaction strength.

We provide a detailed theoretical framework on the testing problem for equality of spectral densities in the bivariate case, but also present the generalization to the m dimensional case and to other statistical applications like testing for zero correlation or clustering of time series data with different length. We prove asymptotic normality of an appropriately standardized version of the test statistic both under the null and the alternative and investigate the finite sample properties of our method in a comprehensive simulation study. Furthermore we apply our approach to cluster financial time series data with different sample length.

description: We study the effects of dilute La and Rh doping on the electronic structure of the relativistic Mott insulator Sr$_2$IrO$_4$ using fully relativistic and magnetically non-collinear density functional theory with the inclusion of an on-site Hubbard $U$. To model doping effects, we have adopted the supercell approach that allows for a realistic treatment of structural relaxations and electronic effects beyond a purely rigid band approach. By means of the band unfolding technique we have computed the spectral function and constructed the effective band structure and Fermi surface (FS), which are readily comparable with available experimental data. Our calculations clearly indicate that La and Rh doping can be interpreted as effective electron and (fractional) hole doping, respectively. In Sr$_{2-x}$La$_x$IrO$_4$ the IMT is accompanied by a moderate renormalization of the electronic correlation substantiated by a reduction of the effective on-site Coulomb repulsion $U-J$ from 1.6 eV ($x=0$) to 1.4 eV (metallic regime $x=12.5\%$). The progressive closing of the relativistic Mott gap leads to the emergence of connected elliptical electron pockets at ($π$/2,$π$/2) and less intense features at $X$ in the FS. The substitution of Ir with the nominally isovalent Rh is accompanied by a substantial hole transfer from the Rh site to the nearest neighbor Ir sites. This shifts down the chemical potential, creates almost circular disconnected hole pockets in the FS and establishes the emergence of a two-dimensional metallic state formed by conducting Rh-planes intercalated by insulating Ir-planes. Finally, our data indicate that hole doping causes a flipping of the in-plane net ferromagnetic moment in the Rh plane and induces a magnetic transition from the AF-I to the AF-II ordering.
Diagnostic Utility of Immunophenotyping by Flow Cytometry for Diagnosis and Classification of Acute Leukemias in Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia

description: Background: Immunophenotypic characterization of acute leukemia is an important clinical application of flow cytometery and has become a powerful tool contributing to proper diagnosis and classification. Objective: To phenotype and classify acute leukemias by flow cytometry using commonly used markers for leukemia diagnosis. Method: A total of 40 pediatric and adult patients diagnosed with acute leukemia were evaluated by flow cytometry with 17 surface and cytoplasmic markers known to be useful in discriminating different types of acute leukemia. Results: 21 of 40 patients (52.5%) were classified as Acute Myeloblastic leukemia (AML) while 19 (47.5%) were identified as Acute lymphoblastic leukemia (ALL). Of all the ALL cases, 10 of the 19 (52.6%) were B-ALL and 47.4% (9/19) were T-ALL. Markers of immaturity HLA-DR and CD34 antigens were co expressed in 61% of AML cases, and 33% of T-ALL cases, whereas CD34 was expressed in 50% of the B-ALL cases. MPO and CD13 were the most commonly expressed markers of AML, whereas CD19 and cCD79a were present in all cases of B-ALL. Cytoplasmic CD3 and CD7 were the most sensitive markers for T-ALL. Discrimination of AML from ALL patients by flow cytometry was 80% concordant with traditional morphology. Notable discrepancies occurred in cases where leukemia cells expressed markers for more than one lineage. Conclusion: Immunophenotyping by flow cytometry provides useful information to confirm diagnoses of standard morphology methodology, to provide classifications where morphology is indeterminate, and to provide further lineage and maturation information for ALL not obtainable by morphology is needed for ALL cases. It thus represents an important tool among many in leukemia classification and is realistic in the resource limited settings. Key words: Leukemia, ALL, AML, Flow cytometry, Immunophenotyping

description: In the common linear regression model the problem of determining optimal designs for least squares estimation is considered in the case where the observations are correlated. A necessary condition for the optimality of a given design is provided, which extends the classical equivalence theory for optimal designs in models with uncorrelated errors to the case of dependent data. For one parameter models this condition is also shown to be sufficient in many cases and for several models optimal designs can be identified explicitly. For the multi-parameter regression models a simple relation which allows verifying the necessary optimality condition is established. Moreover, it is proved that the arcsine distribution is universally optimal for the polynomial regression model with a correlation structure defined by the logarithmic potential. It is also shown that for models in which the regression functions are eigenfunctions of an integral operator induced by the correlation kernel of the error process, designs satisfying the necessary conditions of optimality can be found explicitly. To the best knowledge of the authors these findings provide the first explicit results on optimal designs for regression models with correlated observations, which are not restricted to the location scale model.

description: A model is presented for shifting the manual intensive manufacturing process of complex biomedical devices towards more lean and efcient production process via application of concepts of cyber physical systems in combination with big data and analytics in a closed loop manner. The concept model is capable of handling high product volumes and variety, has ability for self-adaptation and correction in various operating conditions, and ofers real-time quality control. The approach acknowledges the challenge of these industries operating in a strict regulated environment and the higher standards of built-in quality required by developing a closed loop process, proposed to be built in accordance to the requirements of regulatory bodies and current Industry 4.0 practices. The proposed model illustrates that modern manufacturing methodologies and concepts can be integrated and adopted in such highly regulated manufacturing environments and that the model can be deployed to diferent production scenarios.

description: We study a three-body system, formed by a light particle and two identical heavy dipoles, in two dimensions in the Born-Oppenheimer approximation. We present the analytic light-particle wave function resulting from an attractive zero-range potential between the light and each of the heavy particles. It expresses the large-distance universal properties which must be reproduced by all realistic short-range interactions. We calculate the three-body spectrum for zero heavy-heavy interaction as a function of light to heavy mass ratio. We discuss the relatively small deviations from Coulomb estimates and the degeneracies related to radial nodes and angular momentum quantum numbers. We include a repulsive dipole-dipole interaction and investigate the three-body solutions as functions of strength and dipole direction. Avoided crossings occur between levels localized in the emerging small and large-distance minima, respectively. The characteristic exchange of properties such as mean square radii are calculated. Simulation of quantum information transfer is suggested. For large heavy-heavy particle repulsion all bound states have disappeared into the continuum. The corresponding critical strength is inversely proportional to the square of the mass ratio, far from the linear dependence from the Landau criterion.

description: Background: Leprosy is an old chronic infectious disease that continues to be an important public health problem in several developing countries.Host immunologic factors contribute to the clinical outcome in leprosy. This infection is also accompanied by several alterations in lipid metabolism and changes inthesynthesis of a number of acute phase proteins. Objective: To assess the immunological and lipid profile of leprosy patients across the disease spectrum Material and Methods: A crossectional study was conducted at ALERT center which included 30 leprosy patients and 21 healthy controls. An 8 ml of blood sample was collected from30 patients and 21 healthy controls and used for immunological and lipid profile assays. About 200μl of whole blood was stained with antibody conjugated flourochromes and data acquisition was done on FACSCanto II flowcytometer. Lipid profile and C reactive protein tests have been done using chemistry analyzer and qualitative test respectively. Mann-Whitney U test were used to analyze Memory T cells and lipid profile analysis. Result:The percentage of memory T cells (CD45RO+) expressed on CD3+ was significantly higher in PB patients than MB patients. Activated T cells (CD62L-) expressed on CD4+ were significantly higher in PB patients than in MB patients. MB patient's CD3+ effector T cells were significantly higher than the healthy controls. PB patients showed significantly higher CD3+, CD4+ and CD8+ effector memory cells than MB patients. Regarding the lipid profile it showed that, healthy control serum total cholesterol level was significantly higher than MB patients. On the contrary serum HDL level was significantly higher in healthy control than MB patients. Conclusion: This study provides further evidence that there is a significant difference in lipid profile among leprosy spectrum. The percentage of both activated and memory T cells in MB patients are significantly lower than in PB patients and this confirms the unresponsiveness of T cells in MB patients regardless of the high bacterial load in these patients. Recommendation:We recommend that monitoring and regulate the lipid homeostasis of leprosy patients may be useful. We also recommend further study on host immune responses in leprosy diseases in which lipid metabolism and inflammation intersect

description: We study the cosmological implications of interactions between spacetime quanta in the Group Field Theory (GFT) approach to Quantum Gravity from a phenomenological perspective. Our work represents a first step towards understanding Early Universe Cosmology by studying the dynamics of the emergent continuum spacetime, as obtained from a fundamentally discrete microscopic theory. In particular, we show how GFT interactions lead to a recollapse of the Universe while preserving the bounce replacing the initial singularity, which has already been shown to occur in the free case. It is remarkable that cyclic cosmologies are thus obtained in this framework without any a priori assumption on the geometry of spatial sections of the emergent spacetime. Furthermore, we show how interactions make it possible to have an early epoch of accelerated expansion, which can be made to last for an arbitrarily large number of e-folds, without the need to introduce an ad hoc potential for the scalar field.

Assessment of Medical Laboratory request form Completeness and non- Communicated Result to Clinicians in the two public Hospitals Found in Hawassa city, Southern Ethiopia
Creators: name: Ali, Muluberhan
Publisher: name: National Academic Digital Repository of Ethiopia

description: Back ground: Long years ago, history and physical examinations have been the most important part of patient's assessment. However, in recent years, the care of patients has become increasingly dependent on the results of laboratory investigations, and clinical laboratories have become a major component in the delivery of health care.Correctly designed and properly completed request forms are vital for the performance of all laboratory tests to the benefit and satisfaction of users.Results that never reach the physician affect the quality of patient care and unnecessarily wastage of financial health resources. Objective-The objective of this study was to evaluate the content of empty request form to the standard and to assess completeness of filled information on medical laboratory request form and communication of results to users in two public Hospitals of Hawassa city, southern Ethiopia. Methods– ACross-sectional descriptive study design was employed. We collected all request forms submitted to the laboratory during March 15-30, 2015. Data was collected and information was recorded on the data collection sheet and cheeked for its completeness. To assess non-communicated requested result.we reviewed patient medical record. Furthermore to asses factors contributed to improper completion and failed collection, clinicians were asked using pre structured questionnaire. Finally data were analyzed using SPSS version 16.0. Result -The content of HURH empty medical laboratory request form to the standard was 16(72.7%) and Adare hospital 9(40.9%) A total of one thousand nine hundred request forms were studied. Our assessment revealed that, none of the request form was completely filled. All of the request forms 100% studied revealed that three or more gaps in the completion of the items assessed. From reviewed requests 23.8% was uncollected and from this 83(33.1%) was CBC. Conclusion -This study demonstrates that, the standard of completion of request forms was poor. Essential information required on the forms was often missing. This can lead to limited advice given by laboratory personnel and may increase the potential for errors. Conversely, provision of all the information needed on the forms will aid laboratory diagnosis and enhance patient care and save time and resource

description: Αντικείμενο της παρούσας εργασίας αποτελεί το mobile marketing και η επίδραση της διαδικτυακής διαφήμισης στην συμπεριφορά του καταναλωτή. Η αύξηση της χρήσης των κινητών τηλεφώνων με γνώμονα την τεχνολογία επηρεάζει τη συμπεριφορά των καταναλωτών. Το mobile marketing διαφοροποιείται από τα άλλα μέσα marketing όπως η τηλεόραση, το ραδιόφωνο και οι εφημερίδες μέσω της δια δραστικής του φύσης, επειδή παρέχει στον καταναλωτή συνεχή πρόσβαση οποτεδήποτε και οπουδήποτε καθιστώντας το έτσι ένα από τα πιο δυναμικά και αποτελεσματικά προσωπικά μέσα. Ειδικότερα γίνεται αναφορά στα πλεονεκτήματα και τα μειονεκτήματα από την χρήση του mobile marketing, στη στρατηγική και τα εργαλεία που χρησιμοποιεί αλλά και η σκοπιά των επιχειρήσεων προς αυτό. Συγχρόνως εστιάζουμε στην τεχνολογία αλλά και τη σχέση του mobile marketing με τα social media. Στο επόμενο σκέλος της εργασίας αναφερόμαστε στη σημαντικότητα της διαδικτυακής διαφήμισης και στους τύπους που χρησιμοποιούν οι επιχειρήσεις για να διαφημιστούν. Στη συνέχεια επικεντρωθήκαμε στην ανάπτυξη της διαφήμισης μέσω των social media καθώς και τα οφέλη της και τη συμβολή του Google Analytics στην διαφήμιση. Στο τέταρτο σκέλος το ενδιαφέρον εστιάζεται στην συμπεριφορά του e-καταναλωτή στα στάδια της αγοραστικής, στους παράγοντες που επηρεάζουν την συμπεριφορά του σε σχέση με τις νέες τεχνολογίες και στην επίδραση της διαφήμισης. αλλά και στους τρόπους με τους οποίους ικανοποιείται. Στο ερευνητικό κομμάτι το ενδιαφέρον εστιάζεται στην συμπεριφορά του e-καταναλωτή σε σχέση με τη διαφήμιση εξετάζοντας τους παράγοντες που επηρεάζουν τον e-καταναλωτή και εάν τελικά το mobile marketing επιτυγχάνει το σκοπό του να οδηγήσει τον e-καταναλωτή στην αγορά ενός προϊόντος η μιας υπηρεσίας αναλύοντας τις αντιλήψεις τους.

description: We present direct local-probe evidence for strongly hybridized nuclear-electronic spin states of an Ising ferromagnet LiHoF$_4$ in a transverse magnetic field. The nuclear-electronic states are addressed via a magnetic resonance in the GHz frequency range using coplanar resonators and a vector network analyzer. The magnetic resonance spectrum is successfully traced over the entire field-temperature phase diagram, which is remarkably well reproduced by mean-field calculations. Our method can be directly applied to a broad class of materials containing rare-earth ions for probing the substantially mixed nature of the nuclear and electronic moments.
