description: Project team work in Water Action Aid encounters different problem of effectiveness during project implementation of organizational objective. The study assesses the practices and challenges of Project team work case of Water Action Aid. Censes was used to use all stuff members of Water Action Aid organization 30 respondents comprising 1 CEO, 1 Program Manager, 4 Project Managers, 7 Project Coordinators, 11 Frontline Project Staff and 6 key resource persons. Structured questionnaire was used to get information from CEO, Program Manager and Project Managers, whereas FGD questionnaire was used to provoke information from Project Coordinators, Frontline Staff and key resource persons. The study identified that success and faller of project majorly affected by the effectiveness of project teamwork. It was discovered also that the interests and parts of the key Stakeholders were very critical to the effectiveness of the projects. The project teamwork was found to be predominantly not institutionalized (separate organizational body). The study also revealed challenges like Lack of clear Communication, lack of shared vision, problems of Collaboration and participation, problems in leadership style, stimulating work environment, Innovation and creativity and adaptability to change were found to effect on the performance of the projects teamwork in the organization. Finally, it is recommending that team management courses should be incorporated in the training of professional to enhance their skills to higher levels, Professionals should work in teams as opposed to functional structure as there is positive relationship between team effectiveness and project performance and the Government should come up with laws requiring maintenance of records by professional bodies, of events in the water aid project. This would facilitate, among others, continuous improvement of team management in the water aid project. assessment of effectiveness of team works in project management: the case of water action aid project, addis ababa, ethiopia.

description: Contrary to its universal stability and its low rank on borrowability scales (Haspelmath & Tadmor 2009, Haspelmath, Tadmor & Taylor 2010), the lexicalisation of the concept blood (Haspelmath & Tadmor 2009) seems to have undergone a remarkable history of replacements across Bantu Africa, motivated by both internal and external pressures. This is particularly true of Eastern Africa where the widespread loanword *sakame attests to an economically-driven transfer from Southern Cushitic *ts’aq’amee ‘trickle (from a leakage)’ in the context of the Bantu adoption of the practice of bleeding cattle. The contribution is an attempt to unravel some (neglected) aspects of the lexical history of the concept blood in Bantu East Africa and add a higher degree of resolution to the general picture painted by Ehret 1974 and Ehret 1998.

description: Background: Computed tomography (CT) chest findings of granulomatosis with polyangiitis (GPA) may mimic the abnormalities of post primary pulmonary tuberculosis (PTB). In tuberculosis endemic countries, it is essential to differentiate between these two conditions due to therapeutic implications. Aim of the present study was to compare the chest CT findings between GPA and PTB. Methods: In this retrospective study, patients with GPA and lung involvement and patients with sputum positive PTB were included for analysis. Parenchymal lesions including nodules, masses, consolidation, ground glass opacities, cavities, traction bronchiectasis, pleural or pericardial involvement and presence of lymphadenopathy were compared between patients with GPA and PTB. Results: Forty-five patients with GPA and 47 patients with PTB were included. Findings in GPA were nodules in 33 (73.33%), masses in 10 (22.22%), ground glass opacities in 18 (40%), consolidations in 19 (42.22%) and septal thickening in 19 (42.22%) patients. Cavitation of the nodules was noted in 21 (46.67%) and diffuse alveolar haemorrhage was present in 6 (13.33%) patients. Pleural involvement was noted in 5 (11.11%) patients. None of the patients had mediastinal or hilar lymphadenopathy. Findings that were significantly more common in PTB included centrilobular nodules (p<0.0001), consolidation (p<0.0001), cavitation (p=0.022), parenchymal bands (p=0.001), and lymphadenopathy (p<0.0001). Diffuse alveolar haemorrhage was the only finding that was significantly more common in GPA (p=0.043). Additionally, GPA was associated with significantly larger nodules (p=0.003). Conclusion: Combination of CT chest findings may help in differentiating GPA from PTB in tuberculosis endemic areas. Disclosures: None

description: We consider chance-constrained binary programs, where each row of the inequalities that involve uncertainty needs to be satisfied probabilistically. Only the information of the mean and covariance matrix is available, and we solve distributionally robust chance-constrained binary programs (DCBP). Using two different ambiguity sets, we equivalently reformulate the DCBPs as 0-1 second-order cone (SOC) programs. We further exploit the submodularity of 0-1 SOC constraints under special and general covariance matrices, and utilize the submodularity as well as lifting to derive extended polymatroid inequalities to strengthen the 0-1 SOC formulations. We incorporate the valid inequalities in a branch-and-cut algorithm for efficiently solving DCBPs. We demonstrate the computational efficacy and solution performance using diverse instances of a chance-constrained bin packing problem.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: This study is about The Role of Project Risk Management Practices for Project success by taking 12 sample projects from projects practiced in the Commercial Bank of Ethiopia. Therefore, project team members worked on those projects implemented in the Commercial Bank of Ethiopia was contacted to collect data. Questionnaire survey was conducted to collect data from the respondents that consisted of project managers, supervisors, and other related respondents. After being tested for their validity and reliability, in total, 36 questionnaires were distributed and 29 returned and used for analysis of the study. The study uses purposive or judgmental sampling to select respondents that have adequate knowledge and significant role in the projects. The applications used to analyze and examine the hypotheses were the Statistical Package for Social Sciences V.21.The descriptive statistics was used to describe the general result of the variables. In addition, correlation analysis was done to check the correlation between the dependent variable and the independent variables, while regression analysis was used to test the hypotheses developed following the conceptual framework developed from the literature. The finding of the study indicate that effective implementation of project risk management element (Risk planning, Risk Identification, Risk analysis and Risk control and Response) has significant effects on project completion within the scheduled time and budgeted cost. But the impact of risk management practices on project completion with the promised quality is not clear from the finding of the study. But, in the projects taken as a sample, project risk management is not practiced to the level needed and gap is seen between what should be theoretically applied and what is being practiced in the projects. Therefore, this study recommends that project risk management (proper risk identification) should be practiced throughout project life cycle and should involve project team members

description: In the present study, the effect on the chlorophyll a and the total protein content as well as the Chattonella spp. cell viability were examined after concentration-dependent exposure to CuCl2 and Aroclor 1242. The comparison between various raphidophyte strains provides an insight into the different susceptibilities to contaminants of Chattonella subsalsa (CSNAV-1), C. marina var . marina (CMCV-1) and C. marina var. ovata (COPV-2). The microalgae were cultivated in artificial seawater medium. Exponentially growing microalgae (8-10 days in culture) were used for exposure experiments. We observed in all three raphidophyte species cytotoxicity-mediated modifications beginning at concentrations of 150 and 200μM of the heavy metal copper after 24 hours exposure. But interestingly, the three strains exhibited only slight differences in their susceptibility to CuCl2. C. subsalsa and C. marina var. marina cells were first affected at the chlorophyll a level and in cell viability. The total protein amount was reduced significantly only after exposure to 300μM of CuCl2. However, C. marina var. ovata microalgae showed similar reduction curves for all three analysed cytotoxicity endpoints after heavy metal exposure. On the other hand, after Aroclor 1242 incubation the cytotoxic modification pattern indicated clearly the different susceptibilities of the three raphidophyte strains. C. subsalsa cells noticeably exhibited a decrease in the analysed pigment amount (30-20% compared to that of the control) already after 0.007mg/L PCB exposure. In contrast, cell viability and total protein content were slightly reduced and fell below the 50% threshold after 0.7 and 3.3mg/L of Aroclor 1242, respectively. Interestingly, C. marina var. ovata showed almost no cytotoxic modification caused by the PCB mixture. Only the concentration of 0.7mg/L Aroclor 1242 clearly affected the cell viability. As opposed to that we observed a concentration-dependent decrease of cell viability and chlorophyll a amount in CMCV-1 microalgae. These observations confirmed that the susceptibility of the raphidophytes strains CSNAV-1, CMCV-1 and COPV-2 is contaminant- dependent. We showed differences even between two variants of Chattonella (Chattonella marina var. marina and C. marina var. ovata). Furthermore, we were able to show the different mode of action of two common pollutants by simple cytotoxic parameters like total protein and chlorophyll a content as well as by cell counting analysis.

description: Cardiac fibrosis is a pathological process characterized by excessive tissue deposition, matrix remodeling, and tissue stiffening, which eventually leads to organ failure. On a cellular level, the development of fibrosis is associated with the activation of cardiac fibroblasts into myofibroblasts, a highly contractile and secretory phenotype. Myofibroblasts are commonly identified in vitro by the de novo assembly of alpha-smooth muscle actin stress fibers; however, there are few methods to automate stress fiber identification, which can lead to subjectivity and tedium in the process. To address this limitation, we present a computer vision model to classify and segment cells containing alpha-smooth muscle actin stress fibers into 2 classes (α-SMA SF+ and α-SMA SF-), with a high degree of accuracy (cell accuracy: 77%, F1 score 0.79). The model combines standard image processing methods with deep learning techniques to achieve semantic segmentation of the different cell phenotypes. We apply this model to cardiac fibroblasts cultured on hyaluronic acid-based hydrogels of various moduli to induce alpha-smooth muscle actin stress fiber formation. The model successfully predicts the same trends in stress fiber identification as obtained with a manual analysis. Taken together, this work demonstrates a process to automate stress fiber identification in in vitro fibrotic models, thereby increasing reproducibility in fibroblast phenotypic characterization.

description: With 3D printing we desire to be “limited only by our imagination”, and although remarkable advancements have been made in recent years the scope of printable materials remains narrow compared to other forms of manufacturing. Light-driven polymerization methods for 3D printing are particularly attractive due to unparalleled speed and resolution, yet the reliance on high energy UV/violet light in contemporary processes limits the number of compatible materials due to pervasive absorption, scattering, and degradation at these short wavelengths. Such issues can be addressed with visible light photopolymerizations. However, these lower-energy methods often suffer from slow reaction times and sensitivity to oxygen, precluding their utility in 3D printing processes that require rapid hardening (curing) to maximize build speed and resolution. Herein, multifunctional thiols are identified as simple additives to enable rapid high resolution visible light 3D printing under ambient (atmospheric O2) conditions that rival modern UV/violet-based technology. The present process is universal, providing access to commercially relevant acrylic resins with a range of disparate mechanical responses from strong and stiff to soft and extensible. Pushing forward, the insight presented within this study will inform the development of next generation 3D printing materials, such as multicomponent hydrogels and composites.

description: Triacylglycerols (TAGs) are among the most important ingredients in food, cosmetic and pharmaceutical products. Many physical properties of such products, incl. morphology, texture and rheology, are determined by the phase behaviour of the included TAGs. Triglycerides are also of special interest for the production of solid lipid nanoparticles, applied for controlled drug delivery and for encapsulation of bioactive ingredients. In this paper, we study the polymorphic behaviour of complex TAG mixtures, composed of 2 to 6 mixed TAGs, by differential scanning calorimetry and X-ray scattering techniques, aiming to reveal the general rules for their phase behaviour upon cooling and heating. The results show that two or more coexisting phases form upon solidification $(α$, $β'$ and/or $β)$, the number of which depends strongly on the cooling rate and on the number of components in the mixture. No completely miscible $α$- or $β'$-phases were observed. The structure of the most stable $β$ polymorphs, formed upon subsequent heating of the solidified samples, does not depend on the thermal history of the samples. For all mixtures studied, we observed one-component $β$ domains, coexisting with binary mixed $β$ domains with composition and structure which do not depend on the specific TAG ratio in the mixture. In other words, for a mixture with $k$ saturated TAGs we observed $(2k-1)$ different $β$ phases. These conclusions provide some predictive power when analysing the phase transition properties of TAG mixtures.
Spontaneous mirror-symmetry breaking induces inverse energy cascade in 3D active fluids

description: Classical turbulence theory assumes that energy transport in a 3D turbulent flow proceeds through a Richardson cascade whereby larger vortices successively decay into smaller ones. By contrast, an additional inverse cascade characterized by vortex growth exists in 2D fluids and gases, with profound implications for meteorological flows and fluid mixing. The possibility of a helicity-driven inverse cascade in 3D fluids had been rejected in the 1970s based on equilibrium-thermodynamic arguments. Recently, however, it was proposed that certain symmetry-breaking processes could potentially trigger a 3D inverse cascade, but no physical system exhibiting this phenomenon has been identified to date. Here, we present analytical and numerical evidence for the existence of an inverse energy cascade in an experimentally validated 3D active fluid model, describing microbial suspension flows that spontaneously break mirror symmetry. We show analytically that self-organized scale selection, a generic feature of many biological and engineered nonequilibrium fluids, can generate parity-violating Beltrami flows. Our simulations further demonstrate how active scale selection controls mirror-symmetry breaking and the emergence of a 3D inverse cascade.

description: Background: Takayasu’s arteritis (TAK) is an idiopathic systemic vasculitis characterized by the involvement of the aorta and its major branches [1]. The supra-aortic arteries are often involved in TAK, with the reported prevalence ranging from 40% to 84% [2-3]. Importantly, patients with supra-aortic involvement carry a higher risk of neurological severe ischemic events (SIE) [4-5]. The common carotid artery (CCA) is the most affected artery and is more closely associated with neurologic symptoms than other supra-aortic arteries [6]. Ultrasonography (US) has been regarded as the most popular, user-friendly, and repeatable tool for the diagnosis and follow-up of CCA injuries. Our aim was to characterize TAK with supra-aortic involvement and determine the associations between clinical features, carotid US parameters, and neurological SIE. Methods: Patients with supra-aortic involvement including brachiocephalic trunk, bilateral common carotid artery and internal carotid artery, and bilateral subclavian and vertebral artery and baseline carotid US examination were enrolled. Bilateral carotid diameter, intima-media thickness (IMT), and peak systolic velocity (PSV) were measured by US. Then, IMT/diameter ratio (IDR) was calculated. Risk factors associated with neurological SIE were analyzed by multivariate logistic regression. Results: Totally, 295 patients were included, of whom 260 (88.1%) were female, and 93 (31.5%) experienced neurological SIE, with common carotid artery involved (81.7%). Involved supra-aortic artery distribution (p=0.04) and number (p<0.01) differed between neurologic and non-neurologic SIE subjects, showing higher prevalence of common carotid and vertebral artery involvement in cases with neurological SIE and 57.1% neurological SIE patients having more than four involved arteries. The left carotid IMT (p=0.03) and IDR (p<0.01) differed between patients with and without neurological SIE. The left carotid IDR (cut-off value ≥0.55, odds ratio [OR] 4.46; 95% confidence interval [CI] 2.05-9.71; p<0.01) and PSV (≤76 cm/s, OR 3.38; 95% CI 1.62-7.04; p<0.01) and involved supra-aortic artery number (≥4, OR 3.16; 95% CI 1.54-6.47; p<0.01) were independently associated with neurological SIE. Conclusion: The left carotid IDR, PSV and involved supra-aortic artery number would perform as valuable markers for recognizing neurological SIE in TAK patients with supra-aortic lesions.

description: Dieser Vortrag wurde im Rahmen des Tages der Nachwuchsförderung gehalten, der dazu diente, Ideen des Dissertationsvorhabens vorzustellen und anschließend zu diskutieren. Schon eine im Jahr 1999 durchgeführte Befragung von Referendaren zur ihrem Mathematikstudium zeigte folgende Problemlage auf: "Eine deutliche Mehrheit hält die fachwissenschaftlichen Anforderungen im Studium für zu hoch und für zu schwach verbunden mit dem Berufsziel. Viele verlassen die Universität mit (nach eigener Wahrnehmung) unzureichender mathematischer Kompetenz und mit geringem Selbstvertrauen." (Beutelspacher et. al. 2011, S.5) Auch nehmen Lehramtsstudierende im Vergleich zu Diplomstudierenden das Studium weniger als eine vielseitige Lernerfahrung wahr (Vgl. Pieper - Seier 2002, S.397). Um diese unbefriedigende Lage genauer zu verstehen möchte ich mit meiner Dissertation Beziehungen zwischen verschiedenen Merkmalen der Studierenden aufzeigen, die die Einstellungen zur fachmathematischen Ausbildung beeinflussen. Dabei werden neben den subjektiven Relevanzkriterien für fachmathematische Inhalte und deren Anwendung auch die Verbindung des schulmathematischen Wissen zum Fachwissen, die Übertragbarkeit der Inhalte auf die Praxis, das mathematische Weltbild, die Sicht auf die Lehrerrolle und auf die Ziele des Mathematikunterrichts, das eigene Selbstbild, die Motivation für das Studium und vermutlich auch die eigenen fachlichen Fähigkeiten eine Rolle spielen. Damit werden verschiedene Forschungsbereiche in die Arbeit einbezogen. Den größten Bereich bildet die Belief-Forschung in die u.a. das mathematische Weltbild, die Sicht auf die Lehrerrolle und die Ziele des Mathematikunterrichts fallen. Aber auch die Biographie - und Transition-Forschung spielen eine Rolle und bedingen sich gegenseitig.

description: Dijet mass distributions can be used to search for spin-0 resonances that couple to two gluons. I show that there is a substantial impact on such searches from the interference between the resonant signal and the continuum QCD background amplitudes. The signal dijet mass distribution is qualitatively modified by this interference, compared to the naive expectation from considering only the pure resonant contribution, even if the total width of the resonance is minimal and very small compared to the experimental dijet mass resolution. The impact becomes more drastic as the total width of the resonance increases. These considerations are illustrated using examples relevant to the 750 GeV diphoton excess recently observed at the LHC.

Assessment Of Factors Influencing Community Participation In Water Supply Schemes: The Case Of Drought Affected Communities At Dollo-Bay, Somali Region
Creators: name: Fisseha, Tigist

description: eople living in IDPs sites and drought affected areas have substantially greater need for water, sanitation, and hygiene. Their participation in community-based water supply schemes is recommended. Studies on community participated water supply projects have found that demand responsiveness and participation by beneficiaries improve project performance (Isham et al., 1994; Narayan, 1995; Isham & Kahkonen, 1999, 2002; Prokopy, 2005). The main objective of this study was to identify the factors which influence community participation in conflict-affected populations based water supply schemes in IDPs and drought affected communities in Dollo Bay Woreda of Afder Zone. This study has identified the factors which influence user participation in community-based water supply schemes in IDPs and drought affected communities at Dollo Bay Woreda of Afder Zone, Somali Regional State, using primary data. 250 respondents of total households was designated using systematic random sampling technique in an attempt to investigate respondents' attitude towards the impact community participation on the satisfaction of water supply schemes. A two stage random sampling that is selection of the Kebeles and selection of households is made. To capture the rate of participation, two forms of indices were constructed: one to measure attendance in group meetings, and the other to measure their influence on decisions. The relative importance of factors such as group and household characteristics that affect participation were analyzed using linear regression models. Of the two sets of factors, it was found that household characteristics were the most influential. The analysis shows that males actively participated in group meetings. Level of education and involvement of households in other local organizations were the other major factors affecting participation. over all in the water supply context, once the system was installed and functioning without any interruption, it was observed that households were less interested in participating in the meetings. It is households' increased water demand that mainly drives them to participate in the community-managed schemes.

description: Concept issu des sciences infirmières et ici appliqué de façon innovante à l’évaluation, la sécurisation culturelle désigne une démarche visant à faire en sorte que l’évaluation se déroule d’une façon « sûre » pour les parties prenantes et notamment les communautés minorisées cibles de l’intervention étudiée, c’est-à-dire que le processus d’évaluation évite de reproduire des mécanismes de domination (agression, déni d’identité…) liés à des inégalités structurelles. Pour cela, diverses techniques participatives sont mobilisées à toutes les étapes de l’évaluation. La sécurisation culturelle est compatible avec tous types de méthodes. Elle contribue à rendre l’évaluation plus pertinente et utile pour les parties prenantes, et est susceptible d’accroître leur autodétermination.

description: Connectivity is a homotopy invariant property of separable C*-algebras which has three notable consequences: absence of nontrivial projections, quasidiagonality and a more geometric realization of KK-theory for nuclear C*-algebras using asymptotic morphisms. The purpose of this paper is to further explore the class of connective C*-algebras. We give new characterizations of connectivity for exact and for nuclear separable C*-algebras and show that an extension of connective separable nuclear C*-algebras is connective. We establish connectivity or lack of connectivity for C*-algebras associated to certain classes of groups: virtually abelian groups, linear connected nilpotent Lie groups and linear connected semisimple Lie groups.

description: This study investigated how heat demand and fuel loading affect the emissions from outdoor wood-fired hydronic heaters by testing two such appliances using an integrated-duty cycle test method. This test included transient operating conditions, such as cold and hot-starts and modulation between 15 and 100% of maximum rated output. Emission values indicate transient operating conditions produce higher emissions than steady state operation. Cold starts resulted in elevated particulate matter emission factors for both appliances; in one case the particulate matter emission factor for this period was >3500 mg/MJ, which represented emissions 20 times the average value. Additionally, when heat demand was cycled—elevated CO emission factors were measured, with values >5000 mg/MJ for both appliances and more than 3 times the appliance averages, respectively. It follows that the appliance average particulate matter emission factors and CO emission factors were not representative of the actual EF values during these transient periods. In contrast, methane emission factors were relatively stable throughout all tested combustion conditions; however, they were much higher than oil-fired appliances are therefore should not be ignored. These findings demonstrate that wood-fired hydronic heater emissions during transient operating conditions can be significantly greater than emissions during steady-state test conditions, such as those used in typical certification tests. Consequently, certification test values for particulate matter and CO emission factors may significantly underestimate the actual emissions of these appliances when operated in a home. Use of integrated duty-cycle test protocols that capture cold-starts and reloading are better for representing in-use operations of wood-fired hydronic heaters and provide more realistic emissions and delivered efficiency measurements. Implications: In this work we provide information on the particulate and gaseous emissions from two wood fired outdoor hydronic heaters. The units were tested using an integrated duty cycle test method that captured cold starts, reload, cyclic and modulating periods between 15 and 100% of maximum rated output. The data and results show a much higher emission factor than those reported by current certification test methods but are more representative of how the units operate in the field.

description: All six logically possible orders of subject, object and verb are grammatical in Sandawe, but SOV predominates. Other common orders, such as OSV and VS, can be shown to be associated with particular information structure interpretations. The six possible orders also interact in interesting ways with the language’s system of subject-marking morphemes. Word order within noun phrases is more fixed and can be minimally contrastive in a tonal genitive construction. Other interesting word order phenomena in Sandawe include the functional difference in where certain conjunctions are placed in the clause and the relative order of conjoined verbs.

description: We introduce a factorization formula for semi-leptonic $b \to u$ transitions in the exclusive decay mode $B^- \to π^+π^-\ell^-\barν_\ell$ in the limit of large pion energies and large dipion invariant mass. One contribution can be described in terms of a universal $B \to π$ form factor and the convolution of a short-distance kernel $T^{\rm I}$ with the respective light-cone distribution amplitudes (LCDAs) of the positively charged pion. The second contribution, at leading power, completely factorizes, with a short-distance kernel $T^{\rm II}$ convoluted with the leading-twist LCDAs for both pions and the $B$-meson. We calculate the leading contributions to the short-distance kernels $T^{\rm I}$ and $T^{\rm II}$ in fixed-order perturbation theory, and discuss the approximate relations among the resulting $B \to ππ$ partial-wave form factors. Our results provide useful theoretical constraints for phenomenological models that aim to analyze the complete $B \to ππ\ellν$ phase space.
