description: The coalescence phenomenon of drops in liquid/liquid systems is reviewed with particular focus on its technical relevance and application. Due to the complexity of coalescence, a comprehensive survey of the coalescence process and the numerous influencing factors is given. Subsequently, available experimental techniques with different levels of detail are summarized and compared. These techniques can be divided in simple settling tests for qualitative coalescence behavior investigations and gravity settler design, single-drop coalescence studies at flat interfaces as well as between droplets, and detailed film drainage analysis. To model the coalescence rate in liquid/liquid systems on a technical scale, the generic population balance framework is introduced. Additionally, different coalescence modeling approaches are reviewed with ascending level of detail from empirical correlations to comprehensive film drainage models and detailed computational fluid and particle dynamics.

description: Im vorliegenden Beitrag werden schriftliche Bildbeschreibungen von monolingual und bilingual aufwachsenden Schüler*innen der dritten bis sechsten Klasse (N = 288) hinsichtlich ihres Adjektivgebrauchs untersucht. Deskriptiv zeigt sich, dass monolinguale Schüler*innen mehr Adjektive in der Freitextproduktion verwenden als bilinguale Schüler*innen. Mit Ausnahme der prädikativen und wertenden Adjektive, die prädikativ und attributiv vorkommen, zeigt sich ein vermehrter Adjektivgebrauch bei monolingual Lernenden im Vergleich zu bilingual Lernenden. Für die prädikativen Adjektive zeigen sich keine signifikanten Unterschiede; für die wertenden Adjektive zeigt sich ein Mehrgebrauch der bilingualen Schüler*innen. Die gefundenen Effekte können als klein bis mittel klassifiziert werden. Es zeigt sich keine Evidenz für das Vorliegen einer Interaktion zwischen Spracherwerb und Klassenstufe in der Verwendung attributiver und wertender Adjektive. Die Auswertung liefert wichtige Erkenntnisse zum Sprachaneignungsprozess von Adjektiven und zeigt schulischen Handlungsbedarf auf.

description: Coalescence modelling in liquid/liquid dispersions is a challenging task and field of investigations up to now, which becomes apparent when comparing the various existent models with their different and partly even contradictive implementation of influencing factors. In this work, systematic investigations of single drop coalescence were used to compare and validate different coalescence efficiency models regarding the important influencing parameters relative collision velocity and drop size. The impact of these parameters could be analysed independently from each other for the first time and used to identify the best modelling approach. Moreover, the numerical parameter of the coalescence efficiency model could be obtained based on single drop experiments. Using this determined parameter the simulation of drop size distributions within a lab scale stirred vessel was possible. The presented method offers the possibility of independent parameter estimation for population balance equation simulations based on single drop experiments. The application of this systematic approach allows the separate validation of submodels and reliable parameter determination by small scale investigations. On this basis a sound scale-up is possible using population balance equation simulations. (C) 2016 Elsevier Ltd. All rights reserved.

description: We search for runaway stars in the Large Magellanic Cloud (LMC) by computing the space velocities of the visually brightest stars in the LMC that are included in the Gaia TGAS proper motion catalog. We compare with predictions from stellar dynamical models to obtain (peculiar) velocities relative to their local stellar environment. Two of the 31 stars have unusually high proper motions. Of the remaining 29 stars we find that most objects in this sample have velocities in very good agreement with model predictions of a circularly rotating disk model. Indeed the excellent fit to the model implies that the TGAS uncertainty estimates are likely overestimated. The fastest outliers in this subsample contain the LBV R71 and a few other well known emission line objects though in no case do we derive velocities consistent with fast (~100 km/s) runaways. Our results imply that R 71 in particular has a moderate deviation from the local stellar velocity field (40 km/s) lending support to the proposition that this object cannot have evolved as a normal single star since it lies too far from massive star forming complexes to have arrived at its current position during its lifetime. Our findings therefore strengthen the case for this LBV being the result of binary evolution. Of the two stars with unusually high proper motions we find that one, the isolated B1.5 Ia+ supergiant Sk-67 2 (HIP 22237), is a candidate hypervelocity star, the TGAS proper motion implying a very large peculiar transverse velocity (~360 km/s) directed radially away from the LMC centre. If confirmed, for example by Gaia Data Release 2, it would imply that this massive supergiant, on the periphery of the LMC, is leaving the galaxy where it will explode as a supernova.

description: Researchers estimate that ten percent of people who have had COVID-19 experience prolonged symptoms. Often referred to as Long COVID, these symptoms, which can include fatigue, shortness of breath, brain fog, sleep disorders, fevers, gastrointestinal symptoms, anxiety, and depression, can persist for months and can range from mild to incapacitating. In some cases, new symptoms arise sometime after initial infection or evolve over time. While still being defined, these effects are now collectively referred to as Post-Acute Sequelae of SARS-CoV-2 infection (PASC) in the United States, also known as mild-covid or Long COVID. These patients call themselves “long-haulers” and they are facing doubts from medical providers about their symptoms when seeking services and treatment. Although research studies have indicated women are more likely to be long-haulers, it is, in fact, women who have reported experiencing difficulties negotiating a diagnosis by the medical community, repeatedly being told "it's just anxiety." How does disbelief and delegitimation affect the illness experiences of women with contested illnesses? This article seeks to examine, through the lens of Long COVID, how disbelief and delegitimation affect the illness experiences of women with contested illnesses.
Formal Verification of Multi-Paxos for Distributed Consensus

description: Paxos is an important algorithm for a set of distributed processes to agree on a single value or a sequence of values, for which it is called Basic Paxos or Multi-Paxos, respectively. Consensus is critical when distributed services are replicated for fault-tolerance, because non-faulty replicas must agree on the state of the system or the sequence of operations that have been performed. Unfortunately, consensus algorithms including Multi-Paxos in particular are well-known to be difficult to understand, and their accurate specifications and correctness proofs remain challenging, despite extensive studies ever since Lamport introduced Paxos. This article describes formal specification and verification of Lamport's Multi-Paxos algorithm for distributed consensus. The specification is written in TLA+, Lamport's Temporal Logic of Actions. The proof is written and automatically checked using TLAPS, the TLA+ Proof System. The proof is for the safety property of the algorithm. Building on Lamport, Merz, and Doligez's specification and proof for Basic Paxos, we aim to facilitate the understanding of Multi-Paxos and its proof by minimizing the difference from those for Basic Paxos, and to demonstrate a general way of proving other variants of Paxos and other sophisticated distributed algorithms. We also discuss our general strategies and results for proving complex invariants using invariance lemmas and increments, for proving properties about sets and tuples to help the proof check succeed in significantly reduced time, and for overall proof improvement leading to considerably reduced proof size.

description: High-quality microresonator lasers can be realised using semiconductor microcavities containing nanostructures as optically active medium, e.g. quantum wells and quantum dots. These highly efficient lasers are of great importance for prospective applications, such as in optoelectronics. This dissertation thesis investigates two kinds of microcavity lasers. The first part of the thesis concerns quantum-dot micropillar lasers operating in the regime of weak light-matter coupling. The transition from dominating spontaneous emission to lasing operation is analysed in terms of the excitation-power dependent coherence properties and the degree of linear polarisation. To this end, we performed photoluminescence spectroscopy as well as correlation spectroscopy experiments, revealing clear nonlinearities around the lasing threshold. Hence, a full characterisation of the lasing transition of such micropillar lasers is given. In the second part, a quantum-well microcavity operating in the regime of strong coupling is studied. Due to the strength of the light-matter interaction, new eigenstates are created in the microcavity system: excitons-polaritons. These bosonic quasi-particles are known to undergo a phase transition similar to Bose-Einstein condensation, i.e. they accumulate in large numbers in the ground state at a certain particle density. As condensed polaritons are phase-locked, their emission is coherent as well. Combining experimental results obtained from angle-resolved spectroscopy with photon-correlation spectroscopy data, the present work demonstrates that coherent emission from such a condensate can be distinguished from conventional photon lasing by the analysis of two distinct nonlinearities at different particle densities.

description: In addition to a component of the emission that originates from clearly distinguishable coronal loops, the solar corona also exhibits extreme-ultraviolet (EUV) and X-ray ambient emission that is rather diffuse and is often considered undesirable background. Importantly, unlike the generally more structured transition region and chromosphere, the diffuse corona appears to be rather featureless. The magnetic nature of the diffuse corona, and in particular, its footpoints in the lower atmosphere, are not well understood. We study the origin of the diffuse corona above the quiet-Sun network on supergranular scales. We identified regions of diffuse EUV emission in the coronal images from the SDO/AIA. To investigate their connection to the lower atmosphere, we combined these SDO/AIA data with the transition region spectroscopic data from the IRIS and with the underlying surface magnetic field information from the SDO/HMI. The region of the diffuse emission is of supergranular size and persists for more than five hours, during which it shows no obvious substructure. It is associated with plasma at about 1 MK that is located within and above a magnetic canopy. The canopy is formed by unipolar magnetic footpoints that show highly structured spicule-like emission in the overlying transition region. Our results suggest that the diffuse EUV emission patch forms at the base of long-ranging loops, and it overlies spicular structures in the transition region. Heated material might be supplied to it by means of spicular upflows, conduction-driven upflows from coronal heating events, or perhaps by flows originating from the farther footpoint. Therefore, the question remains open how the diffuse EUV patch might be sustained. Nevertheless, our study indicates that heated plasma trapped by long-ranging magnetic loops might substantially contribute to the featureless ambient coronal emission.

Estos datos fueron presentados por la Organización Mundial de la Salud (OMS) en su Informe Mundial sobre la violencia y la salud del año 2001. Según estadísticas también recopiladas por la OMS el suicidio es la decimotercera causa principal de muerte a nivel mundial y representando una tasa mundial de mortalidad anual de 14.5 por 100 mil habitantes lo que equivale a un suicidio cada 45 segundos5. Las estimaciones indican que en el año 2020 las muertes por suicidio podrían ascender a 1,5 millones anuales (OMS. 2004), lo que conlleva a la afectación Emocional, económica y social de miles de personas relacionadas con el suicida, entre familiares y amigos, que son sobrevivientes de este fenómeno social. Lo anterior sin mencionar que las estadísticas hablan de que por cada muerte por Suicidio se realizan de 10 a 20 intentos de autoeliminación (OMS. 2005) llegando a sumar cifras verdaderamente exorbitantes de seres humanos que optan día a día por autoagredirse con el fin último de morir y escapar de un dolor que les es insoportable ya sea a nivel físico o psicológico.

description: The purpose of the research was evaluating the effect of performance appraisal system on employee motivation in East African Pharmaceuticals PLC. Questions raised during the study were,what looks like the existing performance appraisal, level of motivation and how effective PA is in motivating employeein this particular organization. A descriptive research design with survey method was applied. Employee'sreaction towards performance appraisal was evaluated using components of performance Appraisal such as method, process and purpose.Data was obtained through a questionnaire of eighty employees from a representative of ninety twonon managerial staffs from all departments selected using stratified sampling methodsand also secondary data was obtained from administration manual of the organization regarding the issue of performance appraisal system. The collected data were analyzed using SPSS version 20 software. The research findings established that employees were relatively satisfied with the existing PA system (process and Method) but in relation to purposes of performance appraisal systememployees perceived that PA result was used fordevelopmental purposes but it was unjust in relation to promotion, rewarding and pay scheme. The level of motivation of employee in EAP was fair in which employees witnessed theywere motivated. The finding also showed there is a positive correlation between PA and employee motivation. The result from the regression Analysis showed around 20.8 % of employee motivation was caused by PA. As a conclusion the performance appraisal system of the corporation has an effect on employees' motivation. The purpose of performance appraisal only partiallyimplemented it was unjust in relation to promotion, rewarding and pay scheme. In light of the findings, the following recommendations were forwarded. The organization need to enhance motivation, throughproper implementation and regular follow up of Appraisal system. Preparing learning and development plan, fair compensation, promotion and salary payment scheme based on the results of performance appraisal.Other researchers in the area of pharmaceuticals manufacturing should conduct using similar factors of Performance Appraisal which were covered by this work or other Factors of PA to get a betterresult.

Operators from this family are known to control for instance multilinear Calderón--Zygmund operators, square functions, fractional integrals, and the bilinear Hilbert transform. Our results feature a new multilinear version of the Fujii--Wilson $A_\infty$ characteristic that allows us to recover the best known estimates in terms of the $A_p$ characteristic for dependent weights as a special case of the mixed characteristic estimates for general tuples of weights.

description: In the steelmaking industry, the largest share of CO2 emissions comes from the reduction of iron ore. A switch from the blast furnace (BF) / basic oxygen furnace (BOF) route to the direct reduced iron (DRI) process with natural gas followed by the electric arc furnace (EAF) already enables CO2 savings of up to 38%. However, in order to meet the mid- to long-term CO2 targets of the iron and steel industry, further measures are required. Most DRI plants are currently operating on natural gas, which results in approximately 60% hydrogen in the process gas. However, currently projects are underway to determine if DRI units can operate at hydrogen levels at or close to 100%, which could further reduce CO2 emissions by more than 80%.
 In this context, it is important to consider the impact of hydrogen on the refractory lining in the DRI shaft kiln. Previous studies have shown that hydrogen can permeate through refractories and reduce ceramic oxides under certain process conditions. Silica-containing materials are reported to be especially susceptible to hydrogen attack. However, a deeper understanding of corrosion mechanisms is still needed.
 This article presents the first results of experimental work carried out by RHI Magnesita on the impact of hydrogen on refractory systems. Investigations were conducted on the effect of hydrogen exposure on the composition and microstructure of refractory bricks. This enables refractories to be identified that are suitable for lining a DRI shaft kiln where hydrogen is used as a reductant and will support the development of novel hydrogen-resistant refractory solutions.

description: The purpose of this article is to exploit the geometric structure of Quantum Mechanics and of statistical manifolds to study the qualitative effect that the quantum properties have in the statistical description of a system. We show that the end points of geodesics in the classical setting coincide with the probability distributions that minimise Shannon's Entropy, i.e. with distributions of zero dispersion. In the quantum setting this happens only for particular initial conditions, which in turn correspond to classical submanifolds. This result can be interpreted as a geometric manifestation of the uncertainty principle.

description: The fundamental analysis of drop coalescence probability in liquid/liquid systems is necessary to reliably predict drop size distributions in technical applications. For this crucial investigation two colliding oil drops in continuous water phase were recorded with different high speed camera set-ups under varying conditions. In order to analyze the huge amount of recorded image sequences with varying resolutions and qualities, a robust automated image analysis was developed. This analysis is able to determine the trajectories of two colliding drops as well as the important events of drop detachment from cannulas and their collision. With this information the drop velocity in each sequence is calculated and mean values of multiple drop collisions are determined for serial examinations of single drop collisions. Using the developed automated image analysis for drop trajectory and velocity calculation, approximately 1-2 recorded high speed image sequences can be evaluated per minute. (C) 2016 Elsevier Ltd.

description: Organizations are facing competitive and globalized markets, as well as constant environmental changes that often require an organizational restructuring of the business models in order to boost performance. Project management practices can help to achieve strategic goals and increase value of projects in organizations. The Project Management Office (PMO) is an organizational structure created in order to promote and improve project management practice, by adopting appropriate methodologies to achieve high levels of efficiency and effectiveness. The main purpose of this research is to assess the type and roles of PMO in Dashen Bank. Since the importance of PMO is increasing in organizations, the results of this work are useful to provide guidance to organizations on implementing or restructuring their own PMO. To achieve the objectives of this research, a descriptive approach has been used in studying the existing Dashen Bank PMO roles and type. The data collection used questionnaires to whole 82 employees of PMO as a primary data sources and organizational documents and reports as secondary data sources. The collected data analyzed by the use of SPSS v20 and other different methods. The outcomes of this research show that in Dashen Bank out of 25 attributes categorized in to five main roles; Recruit, select, evaluate and determine salaries of project managers, Coordinate vendor/ contractor relationship management, and Manage one or more programs are scored disagreement which means these roles are not being performed in the PMO. The office is supportive, controlling and directive type as needed by the organization with good flexibility. The research recommended that PMO in Dashen bank needs significant improvement on recruiting and assigning staffs to its project management office and sentiment existing roles and type with little improvement to have more benefit from the concept of program/project management office. It also recommended that the PMO should be empowered more and improve in the area of employees recruitment ad vendor relationship in turn it might help to improve its roles and responsibilities, staffing appropriate employees and empowering this PMO in the organization and helping to achieve more projects performance enhancement.

This paper presents an approach to synthesize Arabic handwriting. We segment word images into labeled characters and then use these in synthesizing arbitrary words. The synthesized text should look natural; hence, we define some criteria to decide on what is acceptable as natural-looking. The text that is synthesized by using the natural-looking constrain is compared to text that is synthesized without using the natural-looking constrain for evaluation.

description: We review modeling of astrocyte ion dynamics with a specific focus on the implications of so-called spatial potassium buffering, where excess potassium in the extracellular space (ECS) is transported away to prevent pathological neural spiking. The recently introduced Kirchoff-Nernst-Planck (KNP) scheme for modeling ion dynamics in astrocytes (and brain tissue in general) is outlined and used to study such spatial buffering. We next describe how the ion dynamics of astrocytes may regulate microscopic liquid flow by osmotic effects and how such microscopic flow can be linked to whole-brain macroscopic flow. We thus include the key elements in a putative multiscale theory with astrocytes linking neural activity on a microscopic scale to macroscopic fluid flow.

description: The drop size distribution is an essential process variable in liquid/liquid systems and relevant in many technical applications. It can be described by population balance equations. A coalescence efficiency model was developed to be able to describe the well-known coalescence inhibition due to changing pH value or salt concentration. The model includes the attractive van der Waals and repulsive electrostatic force according to the DLVO theory into the population balance equation framework. This DLVO model can extend existing simulations in a straightforward manner due to a conceptual implementation. Moreover, zeta potential measurements were performed and the model was applied to simulate experiments in a stirred Lank. Hence, the drop size distribution could be predicted well with changing pH value. The results are discussed in comparison to simulations with existing models in literature. (C) 2014 Elsevier Ltd.

subject: coalescence probability

description: The detailed understanding of droplet coalescence is important for the accurate description of liquid/liquid dispersions. A test cell is designed which enables serial examinations of the random coalescence process with high repetition rate, good observability and accuracy of experimental parameters. Within this rectangular test cell a rising droplet collides with a pendant one, while recorded by a high speed camera. The gained experimental data allows a validation and further development of appropriate models. The investigated parameters in this work are the drop size and the superimposed mass transfer influencing the coalescence probability. These examinations were carried out in the EFCE standard test system toluene/acetone/water. The effect of varying the drop size seems to be interfered by the different rising velocities due to buoyancy. Introducing a transferring component has a significant impact on the coalescence process. A transfer direction from disperse to continuous phase results in a coalescence probability of almost 100%, whereas the reverse mass transfer direction induces a repulsion of nearly all droplets.

description: Drop size distributions in liquid/liquid systems within a turbulent flow, being an integral part of many technical applications, can be simulated solving population balance equations. Experimental investigations in stirred toluene/water systems at constant ionic strength of 0.1 mol/L showed that with pH values higher than 11, coalescence is hindered considerably due to electrostatic effects. Within this work, two designated models are used to simulate the transient drop size distributions in a stirred tank, showing that the influence of droplet charge due to a change in pH value or ion concentration cannot be predicted satisfactorily by existing models. This finding motivates a new modelling approach implementing the DLVO theory into the population balance framework.
Entwurf und Implementation einer Bibliothek graphischer Dialoge zur Ein- und Ausgabe von ProSet-Werten

Year: 2003
Subjects: subject: 004

description: Die Prototypingsprache ProSet besitzt lediglich Ein- und Ausgabeoperationen, welche die von Unix vorgegebenen Standardkanäle ( stdin, stdout und stderr) nutzen. Um eine graphische Ein- und Ausgabe von ProSet-Werten zu ermöglichen, wird eine ProSet-Bibliothek mit graphischen Ein- und Ausgabeoperationen konstruiert. Der Aufruf dieser Operationen basiert auf dem Konzept der internen Kontrolle. Die formale Spezifikation der graphischen Dialoge erfolgt mit Hilfe von Zustandsübergangsdiagrammen, die um eine ADA-basierte Notation ergänzt sind. Des weiteren werden ProSet-Konzepte wie Persistenz und Ausnahmebehandlung integriert. Mit der Realisierung einer interreferentiellen Ein- und Ausgabe werden zudem software-ergonomische Aspekte berücksichtigt.

description: We give evidence for intrinsic, defect-induced bulk paramagnetism in SiC by means of $^{13}$C and $^{29}$Si nuclear magnetic resonance (NMR) spectroscopy. The temperature dependence of the internal dipole-field distribution, probed by the spin part of the NMR Knight shift and the spectral linewidth, follows a Curie law and scales very well with the macroscopic DC susceptibility. In order to quantitatively analyze the NMR spectra, a microscopic model based on dipole-dipole interactions was developed. The very good agreement between these simulations and the NMR data establishes a direct relation between the frequency distribution of the spectral intensity and the corresponding real-space volumes of nuclear spins. The presented approach by NMR can be applied to a variety of similar materials and, thus, opens a new avenue for the microscopic exploration and exploitation of diluted bulk magnetism in semiconductors.

description: In this work, we study the parameterized black hole solution by applying the Newman-Janis approach and also examine the Hawking temperature. We consider a Lagrangian field equation associated with the generalized uncertainty principle to study the motion of boson particles. By using semi-classical phenomenon, we analyze the modified Hawking temperature and graphically check the effects of deformation, rotation and correction parameter on black hole geometry. Furthermore, we investigate the logarithmic corrected entropy and also analyze the graphical behavior of deformation and quantum gravity parameter on the logarithmic corrected entropy of black hole.

Assessment On Critical Success Factors Of Construction Projects (A Case Of Ethiopian Shipping And Logistics Services Enterprise Construction Projects
Creators: name: Alem, Ayinetaw
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: This study presents an assessment of the critical success factors in ESLSE construction projects. To achieve this aim, questionnaires were administered to all contractors, project managers, consultants, engineers in different levels, supervisors, foremen, and various technicians who work on ESLSE seven active construction projects in Addis Ababa and Modjo city. The critical success factors are summarized in components, that is, comfort, competence, communication and commitment (COMs). These components frame the four COMs model which forms a basis for evaluation of the questionnaires. An in-depth analysis review of the literature on the critical success factors in the construction projects has affirmed the four COMs model. The interpretation of this quantitative study was conducted with the use of descriptive statistics presented in a tabular format. The findings revealed that more than 61% of the respondents agree and strongly agree that the critical success factors are found practical in ESLSE. There was difference in their application on the four COMs of critical success factors in ESLSE, given the demographic differences between them. The critical success factors identified in this study have provided a way forward for project managers, contractors and other executers in ESLSE construction projects and others. Hence, the results presented in this study can be used as a guideline for successful execution of construction projects in ESLSE. ESLSE can modify the approach it should focus on and adjust trainings towards the employees. More over ESLSE should adjust the requirements the contractors should fulfill.
