description: The cooler synchrotron COSY provides proton and deuteron beams in the energy range of 45 MeV - 2,7 GeV and 75 MeV - 2,2 GeV, respectively, for precision experiments in medium energy physics. High beam quality is achieved by means of electron and stochastic cooling. Electron cooling is applied right after injection. However, in case of intense electron cooled proton (deuteron) beams fast particle losses due to transverse coherent beam oscillations are regularly observed. Unstable behaviour of the intense COSY beam, in particular of the electron cooled one, is investigated. The transverse stability is discussed in terms of transverse coupling impedances. Tune shifts due to high phase space densities are calculated. Possible cures of instabilities are analysed. Active damping of instabilities using a transverse feedback system is considered to be a suitable method to improve beam intensity and quality. A transverse damping system utilizing a pick-up, signal processing electronics, a power amplifier and a stripline deflector was designed, installed and successfully commissioned. Beam current, profile and Schottky spectra measurements with the feedback system turned on and off are presented. The feedback system allows to increase the cooled beam intensity by at least a factor of four when cooling and stacking of repeated injections is applied. Such a procedure is especially useful to increase the luminosity in internal experiments with the polarized beam which has a low injection intensity. For the experiments with unpolarized beams the significant increase of luminosity can be achieved without a decrease of the machine s duty factor. External experiments profit from the small diameter beams and the reduced halo.

description: The Ion Beam Induced Charge Collection (IBIC) technique was used to map the charge collection efficiency (CCE) of a 4H-SiC photodetector with coplanar interdigitated Schottky barrier electrodes and a common ohmic contact on the back side. IBIC maps were obtained using focused proton beams with energies of 0.9 MeV and 1.5 MeV, at different bias voltages and different sensitive electrode configurations (charge collection at the top Schottky or at the back Ohmic contact). These different experimental conditions have been modeled using a two dimensional finite element code to solve the adjoint carrier continuity equations and the results obtained have been compared with experimental results. The excellent consistency between the simulated and experimental CCE maps allows an exhaustive interpretation of the charge collection mechanisms occurring in pixellated or strip detectors.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2003

description: A qualitative study was conducted in Surma woreda, Southern Nations, Nationalities, and People's Region (SNNPR) in order to investigate the socio-cultural factors in decisions related to fertility in Suri ethnic group. Key informants were selected by heterogeneous and snowball sample selection techniques. Key informant in – depth interviews using open-ended questions and observations using checklists were the data collection techniques. Data analysis was done manually in the field and using computer software for handling qualitative data. The Suri has an old tradition of child spacing practice. The reason for their child spacing practices are related to child welfare especially related to child feeding practices, maternal well being for fear of maternal depletion as a result of closely spaced births and the violent way of life that the Suri people often find themselves in. The traditional methods used for child spacing include the rhythm method, post – partum sexual abstinence, and prolonged breastfeeding. Traditional sexual norms such as polygamy and extramarital relation in men and the pastoralist way of life support child spacing practice using the traditional methods. In instances of unwanted pregnancy, the Suri try to induce abortion using local materials and plants. Recommendations were given to establish reproductive health services in the area as well as strengthening the already existing traditional family planning method by providing scientific and reliable information

Η μελέτη αποτελείται από τρία μέρη: Στο πρώτο κεφάλαιο παρουσιάζονται διεξοδικά το σύνολο των βυζαντινών αγιολογικών κειμένων που συντάχθηκαν προς τιμή του Μεγάλου Πατέρα της Εκκλησίας (Βίοι, Εγκώμια, Συναξάρια), εξετάζοντας παράλληλα και τις αυτοβιογραφικές μαρτυρίες που εντοπίζονται στα έργα του. Στο δεύτερο κεφάλαιο υπάρχει μια κατηγοριοποιημένη παρουσίαση των, σχετικών προς τον Άγιο, υμνογραφικών κειμένων (Κοντάκια, Κανόνες, Απολυτίκια κλπ). Στο τρίτο μέρος της εργασίας, έγινε μια συνθετική παρουσίαση των αγιολογικών αντιλήψεων τόσο των αγιολόγων, όσο και των υμνογράφων που είχαν για τον άγιο Γρηγόριο τον Θεολόγο την εποχή του Βυζαντίου, εξετάζοντας παράλληλα τον λόγο για τον οποίο ο Πατέρας της εκκλησίας θεωρούταν μια αγία μορφή της ορθόδοξης εκκλησίας
description: The aim of the master’s thesis was the compilation of the «dossier» of the Saint Gregory the Theologian. The study consists of three parts. In the first chapter, the set of Byzantine hagiographical texts that were written in honor of the Great Father of the Church are thoroughly presented (such as Vita, Encomium, Synaxarium) while also examining the autobiographical testimonies found in his works. In the second chapter there is a categorized presentation of hymnographical texts (Kontakion, Kanones, Apolytics etc) related to the Saint. In the third part of this work, a synthetic presentation of the hagiological concepts of both the hagiographers and the hymn writers who had about Saint Gregory the Theologian during the Byzantine era was made, while examining the reason why the Father of the church was considered a holy figure of the Orthodox church

description: Die Injektion in den Speicherring ist eine wichtige Phase im Betrieb einer Synchrotronstrahlungsquelle. Bei DELTA, einer Synchrotronstrahlungsquelle der dritten Generation, ist eine Automatisierung der Optimierung des Ladungstransfers notwendig, um die Zeit für diese Injektionsphase zu minimieren. Eine exemplarische Untersuchung der vorhandenen Mess- und Korrekturmöglichkeiten im Transferkanal T2 im Rahmen dieser Arbeit zeigte Probleme bei der theoretischen Modellierung auf. Um eine Automatisierung der Injektionsoptimierung zu realisieren, wurde daher auf die Methodik der wissensbasierten Systeme aus dem Fachgebiet der künstlichen Intelligenz zurück gegriffen. Das Ergebnis ist ein kooperierendes Agentensystem, in das ein Expertensystem zur Injektionsoptimierung eingebettet ist. So konnte die Optimierung der Transfereffizienz automatisiert werden, ohne den Betrieb der Beschleunigeranlage zu beeinträchtigen. Der erfolgreiche Einsatz des Agentensystems und speziell des T2-Experten zeigt, dass es möglich und sinnvoll ist, Methoden der künstlichen Intelligenz zur Automatisierung physikalischer Anwendungen einzusetzen.

description: Two distinct models are developed to investigate the transverse magnetic stationary solutions propagating in one-dimensional anisotropic nonlinear plasmonic structures made from a nonlinear metamaterial core of Kerr-type embedded between two semi-infinite metal claddings. The first model is semi-analytical, in which we assumed that the anisotropic nonlinearity depends only on the transverse component of the electric field and that the nonlinear refractive index modification is small compared to the linear one. This method allows us to derive analytically the field profiles and the nonlinear dispersion relations in terms of the Jacobi elliptical functions. The second model is fully numerical, it is based on the finite-element method in which all the components of the electric field are considered in the Kerr-type nonlinearity with no presumptions on the nonlinear refractive index change. Our finite-element based model is valid beyond weak nonlinearity regime and generalize the well-known single-component fixed power algorithm that is usually used. Examples of the main cases are investigated including ones with strong spatial nonlinear effects at low powers. Loss issues are reduced through the use of gain medium in the nonlinear metamaterial core.

description: We present the first version of CYJAX, a package for machine learning Calabi-Yau metrics using JAX. It is meant to be accessible both as a top-level tool and as a library of modular functions. CYJAX is currently centered around the algebraic ansatz for the Kähler potential which automatically satisfies Kählerity and compatibility on patch overlaps. As of now, this implementation is limited to varieties defined by a single defining equation on one complex projective space. We comment on some planned generalizations.

description: Wissensentdeckung in Datenbanken (engl. Knowledge Discovery in Databases, KDD) ist die Bezeichnung für einen nichttrivialen Prozess, der im Kern eine oder mehrere Anwendungen eines Algorithmus aus dem Maschinellen Lernen auf echte Daten beinhaltet. Vorbereitende Schritte in diesem Prozess bereiten die Beispiele, aus denen gelernt wird, auf, erstellen also die Beispiel- Repräsentationssprache. Nachfolgende Schritte wenden die gelernten Ergebnisse auf neue Daten an. In dieser Arbeit wird der gesamte Prozess auf einer konzeptuellen (begrifflichen) Ebene analysiert. Außerdem wird MiningMart beschrieben, eine Software, die den gesamten Prozess unterstützt, aber den Fokus auf die Vorverarbeitung der Daten legt. Diese Vorverarbeitungsphase ist die zeitintensivste Phase des Wissensentdeckungsprozesses. Sie wird durch die Beiträge dieser Arbeit umfassend und auf neuartige Weise unterstützt. Im Ergebnis lässt sich der Aufwand für Benutzer bei der Erstellung, beim Rapid Prototyping, bei der Modellierung, Ausführung, Veröffentlichung und Wiederverwendung von KDD-Prozessen deutlich reduzieren.
description: Knowledge Discovery in Databases (KDD) is a nontrivial process centered around one or more applications of a Machine Learning algorithm to real world data. Steps leading towards this central step prepare the examples from which the algorithm learns, and thus create the example representation language. Steps following the central step may deploy the learned results to new data. In this thesis, the complete process is described from a conceptual view, and the MiningMart software is presented which supports the whole process, but puts its focus on data preparation for KDD. This preparation phase is the most time-consuming part of the process, and is comprehensively supported in new ways by the contributions towards MiningMart made in this thesis. The result are greatly reduced user efforts for rapid prototyping, modelling, execution, publication and re-use of KDD processes.

description: Η παρούσα διπλωματική εργασία εστιάζει στην διερεύνηση της διεργασίας της κροκίδωσης με άλατα σιδήρου και συγκεκριμένα στην προσθήκη υπεροξειδίου του υδρογόνου και τον τρόπο με τον οποίο η παρουσία του στην διεργασία της κροκίδωσης επηρεάζει την απομάκρυνση του αρσενικού από το νερό. Ειδικότερα πραγματοποιήθηκαν πειράματα κροκίδωσης με χρήση του jar test προσθέτοντας διαδοχικά το Η2Ο2 και το κροκιδωτικό ώστε να επιτευχθεί ικανοποιητικά η οξείδωση του αρσενικού και η απομάκρυνση του μέσω δημιουργίας συσσωματωμάτων με το κροκιδωτικό απλοποιώντας με αυτόν τον τρόπο την διεργασία κροκίδωσης σε ένα στάδιο. Δοκιμάστηκαν διαφορετικοί συνδυασμοί συγκεντρώσεων κροκιδωτικών Fe(III)/Fe(II) και Η2Ο2 σε συνθετικό νερό και νερό βρύσης. Πραγματοποιήθηκε σύγκριση με την συμβατική κροκίδωση χωρίς Η2Ο2 ώστε να αναδειχθεί η επίδραση του Η2Ο2. Επίσης μελετήθηκε η επίδραση του pH και του EDTA στην απομάκρυνση του As(III). Επιπλέον, πραγματοποιήθηκε μηχανιστική μελέτη στο σύστημα Fe(III)/ Η2Ο2 με χρήση ενώσεων που παρεμποδίζουν την δράση των κύριων οξειδωτικών του As(III). Οι ενώσεις αυτές ήταν η μεθανόλη, το DMSO και η 2-προπανόλη. Από τα πειράματα αυτά βρέθηκε ότι η οξείδωση και επακόλουθη απομάκρυνση του As(III) ακολουθεί διπλό μηχανισμό. Τέλος, η δράση του Η2Ο2 ήταν ευεργετική με σημαντική αύξηση της απομάκρυνσης του As(III).
description: The present diploma thesis focuses on the investigation of the process of coagulation with iron salts and more specifically, on the addition of hydrogen peroxide and the way with which, its presence influences the As(III) removal from water. In particular, coagulation experiments were performed with jar test method by adding subsequently Η2Ο2 and the coagulant to achieve adequately both the oxidation of arsenic and the removal by creating flocs, simplifying this way the coagulation process in one stage. Different concentration combinations of the Fe(III)/Fe(II) coagulant and the Η2Ο2 were tested in synthetic and tap water. A comparison between this process and the coagulation without Η2Ο2 was made to further show the importance of the Η2Ο2 addition. Also, the effect of pH and EDTA on the As(III) removal was investigated. Additionally, a study of the reaction mechanism in the Fe(III)/ Η2Ο2 system was performed by using compounds that interfere with the main oxidants of As(III). These compounds were methanol, DMSO and 2-propanol. From these experiments it was found out that the oxidation and subsequent removal of As(III) has a double mechanism. Finally, the effect of Η2Ο2 was positive and significant increase of As(III) removal was achieved

description: In this paper, a non-integrated defect relation for meromorphic maps from complete Kähler manifolds $M$ into smooth projective algebraic varieties $V$ intersecting hypersurfaces located in $k$-subgeneral position is proved. The novelty of this result lies in that both the upper bound and the truncation level of our defect relation depend only on $k$, $\dim_{\,\mathbb{C}}(V)$ and the degrees of the hypersurfaces considered. In addition, this defect relation recovers Hirotaka Fujimoto [Theorem 1.1; MR0884636 (88m:32049); Japan. J. Math. (N.S.) 11 (1985), no. 2, 233-264.] when subjected to the same conditions.

On the hysteresis effect in transitions between accretion and propeller regimes

description: Some observations and numerical simulations of disc-magnetosphere interaction show that accretion can proceed in the propeller regime. When the Alfvén radius is beyond the corotation radius, matter climbs up to the high latitudes where the Alfvén surface is inside the equilibrium surface and can accrete. We calculate the fraction of the mass flux in the disc that can accrete onto the neutron star depending on the fastness parameter and the inclination angle between rotation and magnetic axis. We find that, for a narrow range of the fastness parameter, the Alfvén and the equilibrium surfaces intersect at two different critical latitudes. While the system is transiting from the propeller to the accretion regime (the initial rise of an outburst), the disc is already thick and the part of the disc between these two critical latitudes cannot accrete. In transitions from the accretion to the propeller regime (decay of an outburst), the disc is thin, hence, full accretion of matter proceeds until the Alfvén radius moves beyond the equilibrium radius at the disc-midplane. Therefore, the accretion regime commences at a smaller fastness parameter than it ceases. As a result, the transition from the propeller to the accretion regime occurs at a luminosity higher than the transition from the accretion to the propeller regime. We discuss the implications of our results for spectral transitions exhibited by low-mass X-ray binaries.

Year: 2016

description: Background: The 2007 Census of Ethiopia revealed 32630 of the 2739551 Addis Ababa population was persons with disability among which 7,835 are reproductive aged women. Persons with disabilities are the most marginalized groups concerning reproductive health services. Unmet need for family planning (FP) and Contraceptive Prevalence Rate (CPR) in Ethiopia was estimated at 25.3% and 29% in 2011 respectively. It may be difficult to achieve sustainable development goal without a focus on including people with disabilities. Objectives: This study is designed to assess levels and determinants of family planning use and unmet need among women of reproductive age group with disabilities in Addis Ababa. Method: Cross sectional study based on associations of persons with disabilities with stratified sampling was used to select 727 women's with disability. Data were collected using structured questionnaire by eight trained females who completed grade twelve; two of which communicate by speaking and sign language. Data were cleaned and analyzed using Epi data and Stata 12. Descriptive statistics, binary and multivariate logistic regression analyses was employed to identify factors associated with contraceptive use and unmet need for family planning. Cut-off point for the detection of significance is p<0.05. Result: Current CPR among all reproductive age women and sexually active women with disability in Addis Ababa was 44.4% and 64.5% respectively. Unmet need of contraception was 20% among sexually active women with disabilities (10.6% for spacing and 9.4% for limiting) making percentage of demand satisfied 68.9%. Contraception was 6.8 (95% CI: 1.47, 31) times higher in women aged 30-34 compared to age group 45-49. Women whose partners attained primary education had about 3.1 (95% CI: 1.04, 9.5) times more likely to use FP compared with uneducated partners. Unemployed women were 0.8: (95% CI 0.3, 2.04) less likely to use FP methods compared with employed. Women discussing about contraception with partners were 3.3 (95% CI: 1.08, 10.34) times more likely to use FP. While unmet need is less likely among women aged 30-34, 0.05 (95% CI 0.04, 0.7) compared to age group 45-49. Besides women who discuss with their partner about contraception were less likely to have unmet need compared to counterparts 0.23 (95% CI 0.07, 0.7). Those women with number of living children above two are 3.3 (95% CI: 1.03, 10.7) times more likely to have unmet need compared to women with living children less or equal to two. Conclusion and recommendation: Unmet need is found to be high among women with disabilities in Addis Ababa, therefore public and private sectors should promote targeting programs for women with disabilities and their partner for the uptake of the family planning services. Focus should be given to women with disabilities who are unemployed and those whose partners have never been into school. ix

description: Regression and classification are statistical techniques that may be used to extract rules and patterns out of data sets. Analyzing the involved algorithms comprises interdisciplinary research that offers interesting problems for statisticians and computer scientists alike. The focus of this thesis is on robust regression and classification in genetic association studies. In the context of robust regression, new exact algorithms and results for robust online scale estimation with the estimators Qn and Sn and for robust linear regression in the plane with the estimator least quartile difference (LQD) are presented. Additionally, an evolutionary computation algorithm for robust regression with different estimators in higher dimensions is devised. These estimators include the widely used least median of squares (LMS) and least trimmed squares (LTS). For classification in genetic association studies, this thesis describes a Genetic Programming algorithm that outpeforms the standard approaches on the considered data sets. It is able to identify interesting genetic factors not found before in a data set on sporadic breast cancer and to handle larger data sets than the compared methods. In addition, it is extendible to further application fields.

description: One of the leading explanations for the origin of Fermi Bubbles is a past jet activity in the Galactic center supermassive black hole Sgr A$^*$. The claimed jets are often assumed to be perpendicular to the Galactic plane. Motivated by the orientation of pc-scale nuclear stellar disk and gas streams, and a low inclination of the accretion disk around Sgr A$^*$ inferred by the Event Horizon Telescope, we perform hydrodynamical simulations of nuclear jets significantly tilted relative to the Galactic rotation axis. The observed axisymmetry and hemisymmetry (north-south symmetry) of Fermi/eROSITA bubbles (FEBs) due to quasi-steady jets in Sgr A$^*$ can be produced if the jet had a super-Eddington power ($\gtrsim 5\times 10^{44}$ erg s$^{-1}$) for a short time (jet active period $\lesssim 6$ kyr) for a reasonable jet opening angle ($\lesssim 10^\circ$). Such powerful explosions are, however, incompatible with the observed O VIII/O VII line ratio towards the bubbles, even after considering electron-proton temperature non-equilibrium. We argue that the only remaining options for producing FEBs are i) a low-luminosity ($\approx 10^{40.5-41}$ erg s$^{-1}$)) magnetically dominated jet or accretion wind from the Sgr A$^*$, and ii) a SNe or TDE driven wind of a similar luminosity from the Galactic center.

description: The aim of the present thesis to present the short-term treatment effects of the SOS Activator, a functional appliance with an alternative design, for the correction of Class II skeletal discrepancies, which can be combined concurrently with fixed appliances on the upper arch. The results of the cephalometric analysis in children pretreatment and immediately post treatment, showed that SOS Activator is remarkably effective in the correction of Class II skeletal discrepancy in the short term. It has a favorable effect on the skeletal and dental characteristics by the protraction of the mandible and the distal movement of the upper first molars, and on soft tissue variables by reducing the convexity of the soft tissue profile. Additionally, it presents the important advantage compared to other removable functional devices of the simultaneous use of fixed appliances, such as braces and/or expansion devices, on the upper arch

InMAS integrates diverse tools for malware collection (using honeypots) and malware analysis (mainly using dynamic analysis). All collected information is aggregated and accessible through an intuitive and easy-to-use web interface. In this paper, we provide an overview of the structure of InMAS and the various tools it integrates. We also introduce the web frontend that displays all information on different levels of abstraction, from a coarse-grained overview down to highly detailed information on demand.

description: Binary mixtures prepared in an homogeneous phase and quenched into a two-phase region phase-separate via a coarsening process whereby domains of the two phases grow in time. With a numerical study of a spin-exchange model we show that this dynamics first takes a system with equal density of the two species to a critical percolation state. We prove this claim and we determine the time-dependence of the growing length associated to this process with the scaling analysis of the statistical and morphological properties of the clusters of the two phases.

description: Laboratory turnaround time is defined as the length of time from when a test is ordered to the time the result is reported. Various factors such as the type of test, level of urgency, and varying operational procedures have an impact on the turnaround time of laboratory investigations, with longer turnaround times having a negative impact on patient and staff satisfaction. The standard operational procedure for Wukro Hospital is to collect samples from 8:00am to 12:00pm and begin processing at 2:00pm. Under this process patients wait up to 6 hours for tests results which negatively satisfaction. In order to improve the quality of service delivery and increase patient and staff satisfaction the overall efficiency of the laboratory needs to be addressed. This project focuses on the impact of immediate processing of CD4 tests in reducing turnaround time and increasing patient and staff satisfaction at Wukro Hospital. Objective: To reduce turnaround time of CD4 tests from 3-6 hours to an average of 2 hours in Wukro Hospital by the end of August 2013. Methodology: A pre-post study was conducted in wukro hospital From January to March 2013 baseline data was collected on CD4 result turnaround times for 586 patients under the batch processing method and Follow-up data was collected on the turnaround time for receiving CD4 tests results from 640 patients after immediate processing was introduced during June to August 2013. Results: Before the intervention, the average TAT for CD4 test results was 4.38 hours (4.27-4.49 95% CI). The mean TAT decreased to 2.01 hours (2.00-2.04 95% CI) after the intervention (P<0.0001). After introducing the immediate processing method the maximum TAT was 2.5 hours, with the majority of patients 556/640 86.9% receiving their results in 2 hours or less. Work Plan and Budget: The study was conducted from January - August 2013, with a total required cost of 6,050ETB. Conclusion: Processing CD4 tests immediately after sample collection was effective in reducing turnaround time and increasing patient, staff, and community satisfaction. With a more efficient system of laboratory service the hospital can communicate to the community its commitment to service quality by setting the expectation standard for Wukro Hospital at 2 hours for CD4 exam results. Recommendations Acceptance TAT of CD4 test is important for health facilities. It is important to assess the turnaround time of the other laboratory tests.

description: Various supernovae (SN), compact object coalescences, and tidal disruption events are widely believed to occur embedded in active galactic nuclei (AGN) accretion disks and generate detectable electromagnetic (EM) signals. We collectively refer to them as \emph{AGN disk transients}. The inelastic hadronuclear ($pp$) interactions between shock-accelerated cosmic rays and AGN disk materials shortly after the ejecta shock breaks out of the disk can produce high-energy neutrinos. However, the expected efficiency of neutrino production would decay rapidly by adopting a pure Gaussian density atmosphere profile applicable for stable gas-dominated disks. On the other hand, AGN outflows and disk winds are commonly found around AGN accretion disks. In this paper, we present that the circum-disk medium would further consume the shock kinetic energy to more efficiently produce high-energy neutrinos, especially for $\sim$\,TeV$-$PeV neutrinos that IceCube detects. Thanks to the existence of the circum-disk medium, we find that the neutrino production will be enhanced significantly and make a much higher contribution to the diffuse neutrino background. Optimistically, $\sim20\%$ diffuse neutrino background can be contributed from AGN disk transients.

Ο εθελοντισμός είναι μια μορφή κοινωνικής δράσης που προάγει την αλληλεγγύη , την ικανότητα προσαρμογής αλλά και την ανάπτυξη συνοχής μεταξύ των μελών μιας κοινωνίας . Μέσω της εθελοντικής αιμοδοσίας καλύπτονται οι ανάγκες σε αίμα και παράγωγα του και έτσι πραγματοποιούνται οι απαραίτητες μεταγγίσεις . Στην παρούσα διπλωματική εργασία γίνεται μια συνοπτική παρουσίαση του αίματος , της μετάγγισης , του εθελοντισμού και της εθελοντικής αιμοδοσίας.
description: Blood is one of the most important biological fluids. Blood donation is a gift of life for anyone who is in dire need of a blood transfusion. Volunteering is a form of social action that promotes solidarity, the ability to adapt and the development of cohesion between members of a society. Through voluntary blood donation, the needs for blood and its derivatives are covered and thus the necessary transfusions are performed. In this dissertation there is a brief presentation of blood, transfusion, volunteering and voluntary blood donation

description: This paper reports on the investigation of the electronic properties of a thin film CdS/CdTe solar cell with the Ion Beam Induced Charge (IBIC) technique. The device under test is a thin film (total thickness around 10 um) multilayer heterojunction solar cell, displaying an efficiency of 14% under AM1.5 illumination conditions. The IBIC measurements were carried out using focused 3.150 MeV He ions raster scanned onto the surface of the back electrode. The charge collection efficiency (CCE) maps show inhomogeneous response of the cell to be attributed to the polycrystalline nature of the CdTe bulk material. Finally, the evolution of the IBIC signal vs. the ion fluence was studied in order to evaluate the radiation hardness of the CdS/CdTe solar cells in view of their use in solar modules for space applications.

description: Background: Early diagnosis of HIV virus is a determinant for effective treatment of the disease with less costs than a late treatment. Mobile based VCT as part of community HIV testing and counselling service is suited to highly populated settings. Recently the world has agreement on UNAIDS 90-90-90 goals to achieve 90% of people living with HIV to know their HIV status by 2020 and end the AIDS epidemic by 2030. Despite the agreement, HIV testing and counselling continues to be undertaken predominantly in health facilities, even if there is strong evidence on clients' preference to test in the community. Hence, empirically studied cost-effective HIV testing and counselling model is desirable to achieve the goal. Objective: The objective of this study is to describe the cost and compare the cost-effectiveness of Facility, Standalone and Mobile based VCT in Addis Ababa, Ethiopia. Methods: Ingredients costing method and reciprocal cost allocation approach based on a provider perspective in view of economic costs was performed from July 2016 to June 2017 (2009 EFY). Effectiveness is measured by HIV-seropositive individual identified. A cross sectional study design using Decision tree modelling on TreeAge 2018 software was performed. One way and Probabilistic sensitivity analysis were conducted on HIV prevalence, costs, and probabilities. Result: The mean cost per client tested for HIV in Facility, Standalone and Mobile based VCT are USD 4.9, 6.6 and 3.7 respectively. The mean cost per HIV seropositive client identified for the corresponding models are USD 153.6, 154.1 and 138.8 respectively. From the three models, Standalone based VCT is extendedly dominated. The incremental cost of Mobile based VCT is USD 192.1 for every additional HIV positive clients identified when compared to Facility based VCT. Conclusion: More resources should be allocated to HIV prevention through mobile testing to eliminate HIV transmission and start ART early in the disease progression as Mobile based VCT is effective in diagnosing higher number of HIV positive individuals than Facility based VCT with higher costs. As the HIV prevalence in Ethiopia is becoming more concentrated in urban areas, more effort should be made for the provision of HIV counseling and testing service by implementing testing through Mobile based VCT to reach the 90-90-90 goal set by UNAIDS.

description: The main theme of the novel according to Dickens's preface is selfishness, portrayed in a satirical fashion using all the members of the Chuzzlewit family. Dickens introduced the first private detective character in this novel. The original parts issued from January 1843 to July 1844. Chapters 51-54: Chapter 51. Sheds new and brighter light upon the very dark place ; and contains the sequel of the enterprise of Mr. Jonas and his friend -- Chapter 52. In which the tables are turned, completely upside down -- Chapter 53. What John Westlock said to Tom Pinch's sister ; what Tom Pinch's sister said to John Westlock ; what Tom Pinch said to both of them ; and how they all passed the remainder of the day -- Chapter 54. Gives to author great concern. for it is the last in the book

description: The method for functional reduction of Feynman integrals, proposed by the author, is used to calculate one-loop integrals corresponding to diagrams with four external lines. The integrals that emerge from amplitudes for the scattering of light by light, the photon splitting in an external field and Delbrück scattering are considered. For master integrals in $d$ - dimensions, new analytic results are presented. For $d=4$, these integrals are given by compact expressions in terms of logarithms and dilogarithms.
