description: Many believe that certification testing of residential wood heat appliances should provide data indicative of installed performance. Operationally, test methods typically only assess steady-state emissions and fail to include other typical conditions for batch appliances such as start-up. From a fueling perspective, protocols should ensure a consistent approach reflecting common use practices. Ensuring representative conditions and accurate quantification of emissions requires assessing the impact of different start-up conditions and whether or not start-up conditions affect appliance operation during start-up and beyond. This study evaluated the impact of modifying fuel piece sizes and configurations using a “smart” wood-fired hydronic heater (WHH) cordwood appliance. The appliance represents technologies using software and oxygen sensors to improve performance. Since the study used a “smart” appliance, the results likely reflect the least amount of variability found in a WHH cordwood appliance. The analysis consisted of a series of tests that involved changing one fuel variable per series, including: (1) kindling fuel arrangement in the firebox; (2) fuel piece size; and (3) the amount of kindling and starter fuel used. A goal of the study was to determine how each variable affects emissions performance during start-up and the following steady state load. Testing used a dual-stage combustion cordwood WHH equipped with external thermal storage. Particulate matter (PM), carbon monoxide (CO), and delivered heating efficiency were measured, and visible emissions from the stack and secondary combustion chamber were observed. Replicate tests were conducted for each protocol series to evaluate WHH performance reproducibility. These tests found that for a low-mass staged combustion WHH with external thermal storage, the use of different fueling protocols can substantially affect PM and CO emissions. Implications: As test methods move to incorporate measurements beyond steady-state emissions, fueling protocols must be assessed to determine (1) if they reflect typical field procedures and (2) the impact of start-up procedures on the complete test run. This paper assessed how changing start-up conditions affected run variability and PM emission impacts.

Pach's selection theorem says that there are sets $Z_1 \subset U_1,\dots, Z_{d+1} \subset U_{d+1}$ and a point $u$ in $R^d$ such that each $|Z_i| > c_1(d)n$ and $u$ belongs to $\langle z_1,...,z_{d+1} \rangle$ for every choice of $z_1$ in $Z_1,\dots,z_{d+1}$ in $Z_{d+1}$. Here we show that this theorem does not admit a topological extension with linear size sets $Z_i$. However, there is a topological extension where each $|Z_i|$ is of order $(\log n)^(1/d)$.

description: This study intends to assess the project finance appraisal practice of financial institutions; specifically focusing on Dashen Bank S.C. The challenges exist throughout the appraisal process are also assessed and identified. The project appraisal practice was evaluated; whether or not it encompasses measurement parameters concerning Technical, Financial, Market, Managerial, and risk aspects of a proposed project. Primary data was used throughout the research. Quantitative and qualitative data were employed. The quantitative data was collected through a structured questionnaire and the qualitative using an in-depth interview. Since the appraisal process is undertaken on two departments at Head office, the 48credit related staffs of these departments were taken as a population and census method was employed. About 77% or 37 questionnaires were filled and returned. Frequency, percentage, mean and standard deviation ware used to analyze the data. The findings of the research revealed that from the technical dimension the appraisal practice is good enough in addressing aptness of the project schedule, choice of appropriate technology and scale of operation. However plant layout and selection of scale of operation were not well considered. The Bank uses cash flow estimation to forecast the cost-benefit of the proposed project. Payback period, accounting rate of return and net present value (NPV) are the widely used methods of estimation while other alternative methods are not popular in the Bank. In the process, the management aspect got little attention despite the significant contribution it has on project success/failure. Regarding the marketing aspect, Demand-supply gap analysis is the only used to identify the demand for the product of the proposed project defining distribution channels and pricing of the product got little consideration. Project related risk is assessed solely using sensitivity analysis leaving apart qualitative risk analysis and probabilistic risk analysis. The Bank has no defined risk prevention and mitigation strategy specifically for project risks. The restraining factors of the project appraisal process are identified as; low level of quality and completeness of project feasibility study, unavailability of reliable, quality and up to date information, low level of knowledge and skill of project appraiser, lack of well trained and experienced consultants on the specific project, external pressure, management intervention.

description: Das Bakterium Photorhabdus luminescens lebt in einer mutualistischen Symbiose mit Nematoden der Gattung Heterorhabditis. Die Nematoden dringen in das Hämozöl und den Gastrointestinaltrakt verschiedener Insektenarten ein und sondern dort über ihre Körperausgänge die Bakterien ab. Um die Immunabwehr des Insekts zu umgehen und das Insekt zu töten, sekretiert Photorhabdus luminescens eine Vielzahl von Virulenzfaktoren, insbesondere Tc-Toxine. Tc-Toxine sind aus jeweils einer A-, B- und C-Komponente aufgebaut, die einen 1,7 Megadalton großen Holotoxinkomplex bilden. Dieser Komplex enthält ein toxisches Enzym, das nach Übertragung in die Wirtszelle durch Modifikation von Proteinen zum Zelltod führt. In der hier vorliegenden Arbeit wurden die dreidimensionalen Strukturen der pentameren AKomponente (TcdA1-Präpore aus Photorhabdus luminescens) und des Heterodimers der Bund C-Komponente (TcdB2-TccC3 aus Photorhabdus luminescens) mittels Röntgenkristallographie bestimmt. Das TcdB2-TccC3-Heterodimer bildet eine kokonähnliche Struktur und enthält im C-terminalen Bereich von TccC3 eine intrinsische Aspartatproteasedomäne. Diese Domäne spaltet den C-Terminus von TccC3 ab, der als ADPRibosyltransferase C3 die eigentlich toxische Komponente bildet, die wahrscheinlich in einem entfalteten Zustand im Kokon vorliegt. Desweiteren verschließt ein unsymmetrischer β-Propeller den Kokon in TcdB2. Die TcdA1-Struktur zeigt ein Pentamer, das aus einer äußeren Hülle und einem zentralen Translokationskanal aufgebaut ist. Die äußere Hülle enthält Insertionen, die sich in rezeptorbindende Domänen und in ein neuraminidaseähnliches Pentamer falten. Aufgrund der Homologie zu Sialidasen könnte dieses Pentamer Glykoproteine in der Wirtszelle enzymatisch spalten. Die rezeptorbindenden Domänen zeigen Homologien zu Interleukin- und Interferon- Rezeptoruntereinheiten. Durch Interaktionen mit Mitgliedern dieser Zytokinrezeptorfamilie könnte das TcdA1-Pentamer an der Wirtszellmembran stabilisiert und die Penetration der Membran durch den TcdA1-Translokationskanal bei einer Konformationsänderung unterstützt werden.

description: We study the physics of adhesion and the contact mechanics at the nanoscale with a peeling experiment of a carbon nanotube on a flat substrate. Using an interferometric atomic force microscope and an extended force modulation protocol, we investigate the frequency response of the stiffness of the nano-contact from DC to 20 kHz. We show that this dynamic stiffness is only weakly frequency dependent, increasing by a factor 2 when the frequency grows by 3 orders of magnitude. Such behavior may be the signature of amorphous relaxations during the mechanical solicitation at the nano-scale.

description: We expand upon previous work that examined behavior of the iterated Douglas-Rachford method for a line and a circle by considering two generalizations: that of a line and an ellipse and that of a line together with a $p$-sphere. With computer assistance we discover a beautiful geometry that illustrates phenomena which may affect the behavior of the iterates by slowing or inhibiting convergence for feasible cases. We prove local convergence near feasible points, and---seeking a better understanding of the behavior---we employ parallelization in order to study behavior graphically. Motivated by the computer-assisted discoveries, we prove a result about behavior of the method in infeasible cases.

description: This paper focuses on assessing the Practices of project performance evaluation in ethio Telecom. The research is intended to answer the questions, how project performance evaluation mechanisms have been applied in ethio telecom? And what are the challenges of project performance evaluation process in ethio telecom? To answer these questions descriptive research design is used and both qualitative and quantitative methods are applied purposive sampling technique is used to determine sample and sample size. In a way, the researcher tried to assess the evaluation practice of project evaluation process and challenges in application of evolution mechanism. 53 number of respondents have been involved in the study and structured closed ended and open-ended questioners were used. The result revealed ethio telecom practiced all types of project performance evaluation, Used its own force , project manager has formal communication line with all stakeholders and follow planning, execution and reporting process but ethio telecom has limitation on involvement of third parties, in stating clear role and responsibility of project staff, on generating and using relevant, reliable and quality information and in using evaluation result to enhance individual and organizational lesson learning process. The study recommends that there should be involvement of third parties, have to use project evaluation techniques with mandatory and compliance procedure, have state clearly role and responsibility of staffs, Should improve project evaluation capacity through training to improve skill and knowledge of evaluators and have to implement automation to enhance central documentation and to make strong recently organized Project management office. Further researches are also recommended in this study.

description: Inspired by guidelines in the works of linguists (e.g. Bernd Heine, Henry Muzale, Karsten Legère) and natural scientists in Tanzania (e.g. Donald Otieno, Joseph Otieno, Mainen Moshi), I document in a monograph the plant names and utilities of the Hadzabe people in Tanzania. This monograph also builds on the contribution of anthropologists (Frank Marlowe, James Woodburn, Nicholas Blurton-Jones,) who have researched on food substances of the Hadzabe people. In the monograph, I classify plants into Ts’itibiʔi “Trees”, Tcikibiʔi “Shrubs and Thickets”, Mákaleabeʔe “Climbers, Creepers and Tubers”, Énápiʔi “Grasses and Herbs”, and Semeya “Crop Names”. On the abundance of plant species, both Tcikibiʔi “Shrubs and Thickets” and Énápiʔi “Grasses and Herbs” surpass other clusters. In the classification, I use information provided by speakers from all four regions: Tlhi’ika at Kipamba, Mangola at Darajani, Dunduhiya at Sungu, and Yaeda Chini (in the fringes of Siponga). But I rely on the knowledge of at least one informant from each region. I present numerous uses of the plants, focusing mainly on medicinal plants and food resources, which had been the core of the research work. While Marlowe (2010) suggests that the Hadzabe know medicinal plants, I argue that there are Hadzabe people who are more knowledgeable about medicines in the regions. Such persons are regarded as waganga in the villages.

description: We systematically examine the topological, valleytronic, and optical properties of experimentally accessible PbS (001) few-layers, with a focus on the monolayer. With even-odd layer-dependent oscillations and without band inversions, the band gaps cover a wide spectrum from infrared to visible, making the few-layers promising for optoelectronics. Intriguingly, the uniaxial (biaxial) compressive strain can tune the trivial monolayer into a $\mathcal{Z}_2$-topological (topological crystalline) insulator, which may be utilized for controllable low-power electronic devices. Although elliptical dichroism vanishes in the monolayer due to inversion symmetry, optical pumping provides an efficient tool to characterize the three phases and to realize charge, spin, and valley Hall effects in optoelectronic transport that are tunable by external strain and light ellipticity.

description: Background: Anti-glomerular basement membrane (GBM) disease is a small-vessel vasculitis affecting glomerular and/or alveolar capillaries where autoantibodies are deposited along the basement membrane. Renal function at diagnosis and percentage of crescents in non-sclerotic glomeruli are established prognostic factors, but there are reports that autoantibody levels at diagnosis also matters. However, very little is known about autoantibodies produced after start of treatment. The autoantibodies are directed towards the NC1 domain on the α3-chain of collagen IV (NC1(α3)IV) where 2 major epitopes have been identified, denoted Ea and Eb, but their relative contribution to the pathogenesis is unclear. IdeS is a streptococcal enzyme specifically cleaving human IgGs within minutes, and it was used in the GOODIDES-01 trial. The aim of this study was to elucidate the role of rebound of autoantibodies and the relative contribution of autoantibodies with different epitope specificity. Methods: The GOODIDES-01 trial recruited 15 patients in 5 European countries, all received a single dose of IdeS on top of standard treatment. Patients were followed prospectively for 6 months. In sera, reactivity towards the entire NC1(α3)IV (denoted α3) as well as each of the epitopes Ea and Eb were measured using ELISA. Results are presented in optical density (OD). Descriptive statistics, group comparisons using Mann-Whitney multiple ranks test or a mixed model for analysis of variance with Hólm-Sídak method for correction and graphs were generated using GraphPad Prism version 9.0. Results: In 4 patients autoantibodies did not rebound, they all displayed renal survival at 6 months. In 4 patients autoantibodies against Ea and Eb were of similar proportion at rebound, 2 of them were still dialysis dependent at 6 months. In 5 patients autoantibodies against the Ea epitope dominated at rebound, 1 of them were dialysis dependent at 6 months. In 2 patients the rebound was dominated by autoantibodies against the Eb epitope, both of them were dialysis dependent at 6 months. Conclusions: Rebound of autoantibodies was in this study associated with adverse prognosis. Patients with more reactivity toward the Eb epitope at rebound were more often dialysis dependent at 6 months compared to patients with reactivity towards only Ea. This could indicate that autoantibodies towards the Eb epitope are more pathogenic and could be a potential early marker of a less favorable renal prognosis.

description: This presentation seeks to explore what has been termed an optional i- prefix on some Class 5 roots in Mbugwe (Bantu F34). We will examine some previous analyses of Class 5 nouns in Mbugwe and the distribution of this initial i- as attested in my data, before I present my hypothesis that the i- prefix is an augment.

subject: FOS: Social sciences

description: La récolte d'incidences est une approche qualitative en évaluation ex post. Plutôt que de tester un impact spécifique de l'intervention étudiée, elle consiste, en collaboration avec les parties prenantes, à identifier et collecter des preuves empiriques concernant des effets intentionnels ou non, à étudier comment ces effets ont été produits et si et comment l'intervention a pu jouer un rôle dans ce processus, avant de valider ces résultats à l’aide de sources externes. La récolte d'incidences est une approche axée sur l'utilisation : elle vise à produire des connaissances pour l'action. Elle est particulièrement utile dans le cas d'interventions complexes, quand les effets d’une intervention ne sont pas connus ou identifiés au préalable ou dans le cas d’une intervention significativement modifiée depuis son lancement.

Efficient frequency response computation for structures with structural damping

Modal analysis

description: The modern procedure for analyzing the dynamics of a large, complex structure, such as an automobile, is to use the finite element method to discretize the structure with millions of degrees of freedom. For the steady-state response to a harmonic excitation, a frequency response problem (FRP) is derived for the finite element discretization. To ease computational cost, modal analysis is performed, creating a corresponding FRP in an approximating modal subspace with a substantial reduction in dimension. Typically, more than one level of structural damping is present in a complex structure. This results in a fully populated modal damping matrix, so that the frequency-dependent coefficient matrix of the modal FRP is full. This problem is traditionally solved using a brute-force approach, which can be prohibitively expensive since it requires O(n³) operations for each of the hundreds of frequencies. This dissertation presents two new approaches for solving modal FRPs of automobile structures that have any composition of structural damping. Each approach requires a single frequency-independent O(n³) operation which changes the full coefficient matrix of the modal FRP into one with a simpler form. The first approach presents a new method which creates a low rank approximation of the modal structural damping matrix. The second approach is used when the modal structural damping matrix has high rank and relies on a new method for determining an accurate eigenvalue decomposition of a complex symmetric matrix. Computing responses using these two approaches then only requires O(n²) operations for every frequency. Automobile companies perform analyses on computers with multi-core CPU processors and graphics processing units which can perform dense linear algebra operations with high efficiency. This dissertation shows how the two approaches are implemented to take advantage of these parallel technologies. The accuracy and performance of the two new approaches are presented and compared with the brute-force approach

Assessment Of Project Risk Management Practice Of It Project: The Case Of Ethio Telecom
Creators: name: Mekonnen, Rediat
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: This study is targeted to assess project risk practice of IT project in Ethio Telecom by addressing the process undergone namely: risk planning, risk identification, risk analysis, risk response, and risk monitoring and controlling. The primary data was collected from 60 respondents out of the total population of 387 which are selected using non-probability purposive sampling. And the collected data analyzed using SPSS version 20.0. Then the data presented quantitatively using descriptive statistics. Semi-structured interview was also conducted with 4 project managers, and analyzed qualitatively by integrating secondary data obtained from TEP chart, reports, magazines, And Ethio telecom booklet. The findings obtained about the practice of risk planning revealed that the project have a systematic risk planning process and it is prepared with the involvement of relevant stakeholders and consideration of an expert judgment. However, team members do not receive training about how to handle risks. Regarding the practice of risk identification, there is no involvement of all team members; the project uses a measurement system to analyze risk and subjective probability assessment to assess the probability of risk occurrence. While responding to risk the project considers factors such as budget, schedule and resources. There is little practice of risk monitoring and control. And this little practice is not done in accordance with the goal and objective of the project. Therefore, the project should improve its risk management practice by filling the gap between the real practice in the project and the theory.

description: Der Bereich umweltbezogener Dienstleistungen scheint ein Paradebeispiel für den raschen Wandel von Berufen und Berufsbildern zu sein. Dieser Beitrag untersucht die Folgen für berufliche Identität auf der Grundlage einer Markt- und Berufs-Befragung der Schweizer Umweltdienstleister (N=406). Untersucht wird, ob die berufliche Identität eher von professions-soziologisch fassbaren Bedingungen abhängt (Professionalisierungsgrad der Berufsgruppe), oder eher von der psychologisch fassbaren individuellen Expertise (Berufserfahrung). Berufliche Identität wird hier im Sinne Haußers (1995) operationalisiert, und zwar als berufliches Selbstkonzept, beruflicher Selbstwert und berufliche Kontrollüberzeugungen. Wie sich zeigt, ist der Einfluss auf die berufliche Identität sehr viel deutlicher bei der spezifischen Berufsgruppenzugehörigkeit als bei der individuellen Expertise.
