Wastewater treatment processes

description: Petroleum wastewater is produced by petroleum exploration and production operations and industries, such as refineries, metallurgy, and petroleum transportation. In this study the electrochemical methods were investigated which are used to treat petroleum wastewater. Conversion, separation, and combined methods are the three major electrochemical methodologies for wastewater treatment. Electrooxidation, electroreduction, and electrochemical destruction are notable conversion processes. Separation techniques include electro-deionization, electro-filtration, electrodeposition, electrodialysis and electro-flotation. Electrocoagulation, electro-Fenton, and electrocatalysis are among the combined processes. The wastewater treatment techniques also use EAOPs when treating effluents that contain organic waste. Electrochemical wastewater treatment operations are considered green technologies as they can operate in harmony with renewable energy sources and can create oxidants by using electrons instead of toxic materials. The physicochemical properties of petroleum wastewater, electrode materials, and, ultimately, the overall implemented system determine the efficacy of an electrochemical treatment method. It is crucial to establish the criteria for selecting the most suitable electrochemical technique, while also considering the operational efficiencies. The COD and sulfide removal experiment performed in this study revealed that electrocoagulation using Fe electrodes was very successful in almost quantitative elimination of sulfur (99%) but only partially effective in removal of COD (36%). After electrocoagulation, electrooxidation and electro-Fenton procedures were utilized as iterative treatments to remove the residual COD. The iterative electrooxidation was performed using BDD at the two distinct temperatures of 25°C and 60°C. At 60°C, it was observed that 99% of the remaining COD had been eliminated. Alternatively, an iterative electro-Fenton procedure using Fe electrodes at 25°C was carried out following the electrocoagulation. The outcomes showed that 92% of the COD was removed without the necessity to increase the temperature. Depending on the parameters and conditions, it should be demonstrated that various electrochemical treatments can be combined to effectively treat petroleum wastewater.

description: The gauging of the lepton flavour group is considered in the Standard Model context and in its extension with three right-handed neutrinos. The anomaly cancellation conditions lead to a Seesaw mechanism as underlying dynamics for all leptons; requiring in addition a phenomenologically viable setup leads to Majorana masses for the neutral sector: the type I Seesaw Lagrangian in the Standard Model case and the inverse Seesaw in the extended model. Within the minimal extension of the scalar sector, the Yukawa couplings are promoted to scalar fields in the bifundamental of the flavour group. The resulting low-energy Yukawa couplings are proportional to inverse powers of the vacuum expectation values of those scalars; the protection against flavour changing neutral currents differs from that of Minimal Flavor Violation. In all cases, the $μ-τ$ flavour sector exhibits rich and promising phenomenological signals.

Discontinuity in the asymptotic behavior of planar orthogonal polynomials under a perturbation of the Gaussian weight

Year: 2016

description: We consider the orthogonal polynomials, $\{P_n(z)\}_{n=0,1,\cdots}$, with respect to the measure $$|z-a|^{2c} e^{-N|z|^2}dA(z)$$ supported over the whole complex plane, where $a>0$, $N>0$ and $c>-1$. We look at the scaling limit where $n$ and $N$ tend to infinity while keeping their ratio, $n/N$, fixed. The support of the limiting zero distribution is given in terms of certain "limiting potential-theoretic skeleton" of the unit disk. We show that, as we vary $c$, both the skeleton and the asymptotic distribution of the zeros behave discontinuously at $c=0$. The smooth interpolation of the discontinuity is obtained by the further scaling of $c=e^{-ηN}$ in terms of the parameter $η\in[0,\infty).$

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

description: This research is aimed at assessing the practices and challenges of application of land administration governance principles in urban land development and management in Nifas Silk Lafto Sub-city of Addis Ababa City Administration. The study assessed the problems in applying the land administration governance dimensions (principles). In order to achieve the above mentioned objectives, primary and secondary data was collected. Content and literature review was conducted from available scholarly studies, land management manuals and program documents. A conceptual framework was developed from the literature review and qualitative methodology was employed. Survey Questionnaires, interview and document review checklists were used as data collection tools. The qualitative interview and content data was analyzed using narrative explanations. The survey questionnaire responses were analyzed descriptively. The findings of the study revealed that land development and management processes are not transparent to the service users. Weak citizen participation in the land development and management and unequal treatment of clients in the service provision were observed as key problems of applying land administration governance principles. The study also revealed that service users were dissatisfied on the performance of land development and management officials in terms of service delivery per the needs of customers. Based on the findings of the study, the study concluded with the recommendation that concerned government bodies in the land development and management institutions need to improve performance, involve citizens and design systems of transparency in the study sub city. The service provision and the systems in place should ensure equal treatment of customers. Based on the assessment, items of the transparency dimension score is below the cutoff point. So, the perception of respondents had assessed the transparency of the office as unsatisfactory. There are another problems based on observation, service users always make a repeated compliant in relation with service delivery, no conducive work environment, most service recipients came to the office redundantly and waste their time to settle unaccomplished cases, the citizen charter of the office is not in proper function and inconsistencies on interpreting land related legislations.

description: Within the superfield approach, we consider the nonlocal generalization of the Wess-Zumino model and calculate the one-loop low-energy contributions to the effective action. Four different nonlocal models are considered, among which only the first model does not reduce to the standard Wess-Zumino model when we take the parameter of nonlocality of the model, $Λ$, much greater than any energy scale; in addition, this model also depends on an extra parameter, $ξ$. As to the other three models, the result looks like the renormalized effective potential for the usual Wess-Zumino model, where the normalization scale $μ$ is replaced by the $Λ$. Moreover, the fourth model displays a divergence which can be eliminated through the appropriate wave function renormalization.

description: Magnesium alloy AZ31 metal sheets were formed at room temperature with a pulsed magnetic field induced by a flat coil. For this a die with variable die radius and inside diameter was used. The forming results were evaluated regarding to deformation, die radius, inside diameter, micro hardness, texture examination of forming area and energy input. In addition high velocity forming process was compared to a quasi-static forming process at room temperature. Therefore an experimental setup with an adapted punch was constructed. Punch geometry was defined in dependence of the high velocity forming structure of a sample at well-defined energy input. By comparing texture and micro hardness at forming area a distinction of high-speed forming process and quasi-static process is determined.
Closing the stellar labels gap: An unsupervised, generative model for $\textit{Gaia}$ BP/RP spectra

description: The recent release of 220+ million BP/RP spectra in $\textit{Gaia}$ DR3 presents an opportunity to apply deep learning models to an unprecedented number of stellar spectra, at extremely low-resolution. The BP/RP dataset is so massive that no previous spectroscopic survey can provide enough stellar labels to cover the BP/RP parameter space. We present an unsupervised, deep, generative model for BP/RP spectra: a $\textit{scatter}$ variational auto-encoder. We design a non-traditional variational auto-encoder which is capable of modeling both $(i)$ BP/RP coefficients and $(ii)$ intrinsic scatter. Our model learns a latent space from which to generate BP/RP spectra (scatter) directly from the data itself without requiring any stellar labels. We demonstrate that our model accurately reproduces BP/RP spectra in regions of parameter space where supervised learning fails or cannot be implemented.

description: In this paper, a method is presented for the virtual process design of combinations of deep drawing and electromagnetic forming. With suitably chosen parameters, such process combinations of a quasi-static and an impulse forming process extend forming limits of classical, purely quasi-static forming. To determine parameters leading to the desired forming result, a numerical optimization algorithm is employed. The parameters to be adjusted comprise parameters of the triggering current, such as frequency, amplitude, damping, etc., geometric parameters of the tool coil and parameters of the deep drawing process, as, e.g., drawing radii or tribological parameters. To reduce the required number of evaluations of the target function, a gradient based numerical optimization scheme is employed following directions of decent in the parameter space. The quality of a given parameter set is determined by computing the distance of the simulated forming result to the prescribed ideal shape via a finite element simulation. Forming limits are incorporated by so called forming limit surfaces as constraints to the optimization process, considering rate dependence and prestrain in the second impulse forming step.

Dipolar exchange induced transparency with Rydberg atoms
Creators: name: Petrosyan, David
Publisher: name: arXiv
Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A three-level atomic medium can be made transparent to a resonant probe field in the presence of a strong control field acting on an adjacent atomic transition to a long-lived state, which can be represented by a highly excited Rydberg state. The long-range interactions between the Rydberg state atoms then translate into strong, non-local, dispersive or absorptive interactions between the probe photons, which can be used to achieve deterministic quantum logic gates and single photon sources. Here we show that long-range dipole-dipole exchange interaction with one or more spins -- two-level systems represented by atoms in suitable Rydberg states -- can play the role of control field for the optically-dense medium of atoms. This induces transparency of the medium for a number of probe photons $n_p$ not exceeding the number of spins $n_s$, while all the excess photons are resonantly absorbed upon propagation. In the most practical case of a single spin atom prepared in the Rydberg state, the medium is thus transparent only to a single input probe photon. For larger number of spins $n_s$, all $n_p \leq n_s$ photon components of the probe field would experience transparency but with an $n_p$-dependent group velocity.

Year: 2018

description: The main objective of the study is to investigate the effect of customers' attitude on general insurance purchase intention in Addis Ababa, Ethiopia. In this research, customers of general insurance service were targeted as the population while Cognition, Emotional Affect, and Subjective Norm were taken as predicting variables towards Purchase Intention as dependent variable. The researcher used questionnaire written both in Amharic and English to collect relevant data for the research questions from 423 sample respondents of five insurance companies which were selected using convenience sampling. From the total questionnaires distributed, 386 were considered valid for analysis. The analysis was performed using frequency, mean, standard deviation, correlation and regression by means of SPSS software. Then the collected data were analyzed and interpreted. And the findings of the study reveal that all the independent variables: Cognition, Emotional Affect, and Subjective Norm have a positive and significant effect on purchase intention. Pearson correlation and multiple regression analysis were used to examine the relationship between the independent variables and Purchase Intention using SPSS version 20.0 and the findings showed that all the independent variables have a positive and significant effect on Purchase Intention. Thus insurance companies should give due emphasis to address these elements for increment of their volume of customers.

description: We present a newly developed software package which implements a wide range of routines frequently used in Weak Gravitational Lensing (WL). With the continuously increasing size of the WL scientific community we feel that easy to use Application Program Interfaces (APIs) for common calculations are a necessity to ensure efficiency and coordination across different working groups. Coupled with existing open source codes, such as CAMB and Gadget2, LensTools brings together a cosmic shear simulation pipeline which, complemented with a variety of WL feature measurement tools and parameter sampling routines, provides easy access to the numerics for theoretical studies of WL as well as for experiment forecasts. Being implemented in python, LensTools takes full advantage of a range of state--of--the art techniques developed by the large and growing open--source software community (scipy,pandas,astropy,scikit-learn,emcee). We made the LensTools code available on the Python Package Index and published its documentation on http://lenstools.readthedocs.io

description: Laser impact welding is a solid-state, collision-based welding process. In this process, laser-generated optical energy is converted to kinetic energy through the ablation at the surface and confinement of the gas generated between a flyer and backing plate. The launch of the flyer can be affected by many factors, for example, backing material, ablative layer, and flyer thickness. In this paper, the effect of three backing materials: glass, polycarbonate and cellophane tape, were studied with different laser spot size and commercially pure aluminum alloy 1100 was used as the flyer. The results show that glass can provide the most efficient launches, but is damaged. Polycarbonate is a good compromise between efficiency and robustness. Welding is possible between many similar and dissimilar material pairs. In this study, commercially pure nickel was joined to commercially pure nickel. There are several possible geometric arrangements of the target relative to the flyer. With flat targets, metallurgical bonding takes place along the edges of the spot, and jet was observed in the center of the spot. Corrugated targets provide more surface area for metallurgical bonding. In this paper, the flyer launch velocity-time profile is also demonstrated using a photon Doppler velocimetry technique.

description: Proxima b is a planet with a minimum mass of 1.3 MEarth orbiting within the habitable zone (HZ) of Proxima Centauri, a very low-mass, active star and the Sun's closest neighbor. Here we investigate a number of factors related to the potential habitability of Proxima b and its ability to maintain liquid water on its surface. We set the stage by estimating the current high-energy irradiance of the planet and show that the planet currently receives 30 times more EUV radiation than Earth and 250 times more X-rays. We compute the time evolution of the star's spectrum, which is essential for modeling the flux received over Proxima b's lifetime. We also show that Proxima b's obliquity is likely null and its spin is either synchronous or in a 3:2 spin-orbit resonance, depending on the planet's eccentricity and level of triaxiality. Next we consider the evolution of Proxima b's water inventory. We use our spectral energy distribution to compute the hydrogen loss from the planet with an improved energy-limited escape formalism. Despite the high level of stellar activity we find that Proxima b is likely to have lost less than an Earth ocean's worth of hydrogen before it reached the HZ 100-200 Myr after its formation. The largest uncertainty in our work is the initial water budget, which is not constrained by planet formation models. We conclude that Proxima b is a viable candidate habitable planet.

description: Pulse magnetic welding can be seen as a well developed manufacturing process. However, the realization of this technology implies a high degree of knowledge concerning the intrinsic mechanisms of current transmission and force generation and accordingly a high potential of optimization can be expected. Modelling pulse magnetic forming processes requires a transient electromagnetic calculation in order to obtain the generated currents and forces. The prediction of the deforming result requires an explicit structural simulation, as the forming process is conducted in timescales of a few 100 μs. A close investigation of the relevant physical entities is carried out with ANSYS Workbench and ANSYS Emag. Furthermore, the results of the Emag calculations are used as boundary conditions for explicit structural simulations with ANSYS AUTODYN in order to predict the needed charging energy for a joining process. For validation, a comparison between simulated and measured results with respect to magnetic flux density and discharge current is shown.

description: Einstein's theory of gravity has been extensively tested on solar system scales, and for isolated astrophysical systems, using the perturbative framework known as the parameterized post-Newtonian (PPN) formalism. This framework is designed for use in the weak-field and slow-motion limit of gravity, and can be used to constrain a large class of metric theories of gravity with data collected from the aforementioned systems. Given the potential of future surveys to probe cosmological scales to high precision, it is a topic of much contemporary interest to construct a similar framework to link Einstein's theory of gravity and its alternatives to observations on cosmological scales. Our approach to this problem is to adapt and extend the existing PPN formalism for use in cosmology. We derive a set of equations that use the same parameters to consistently model both weak fields and cosmology. This allows us to parameterize a large class of modified theories of gravity and dark energy models on cosmological scales, using just four functions of time. These four functions can be directly linked to the background expansion of the universe, first-order cosmological perturbations, and the weak-field limit of the theory. They also reduce to the standard PPN parameters on solar system scales. We illustrate how dark energy models and scalar-tensor and vector-tensor theories of gravity fit into this framework, which we refer to as "parameterized post-Newtonian cosmology" (PPNC).

description: CEBAF, the Continuous Electron Beam Accelerator Facility, has been actively serving the nuclear physics research community as a unique forefront international resource since 1995. This CW electron linear accelerator (linac) at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab) has continued to evolve as a precision tool for discerning the structure and dynamics within nuclei. Superconducting RF (SRF) technology has been the essential foundation for CEBAF, first as a 4 GeV machine, then 6 GeV, and currently capable of 12 GeV. We review the development, implementation, and performance of SRF systems for CEBAF from its early beginnings to the commissioning of the 12 GeV era.

description: Civil society has emerged as an important catalyst of change in the development and democratic processes, making tremendous contributions in developing countries where abject poverty still dominates the livelihood of the people; democratic values and system of governance are yet in their infancy. With this in mind, the Government of Ethiopia has recently come up with the Charities and Societies Proclamation (CSP) to aid and facilitate the role of Charities and Societies in Ethiopia. Therefore, the main objective of this thesis is to assess the impact of the CSP on Women and Children Civil Society Organizations (CSOs) in Addis Ababa. To achieve the objectives of this thesis, the research method used was descriptive case study. Through the use of primary and secondary data sources, the researcher has gathered the necessary information regarding the impact of the proclamation. By employing purposive sampling technique those Charities and Societies working for women and children in Addis Ababa were purposively selected in consultation with the Network of Ethiopian Women's Association (NEWA) and the Union of Ethiopian Women Charitable Association (UEWCA). Semi-structured interviews were carried out with the selected eight Charities and Societies. In addition, structured interviews of key informants were carried out with three donor organizations and with the Charities and Societies Agency. Information obtained from these sources was then analyzed qualitatively based on descriptive analysis. As the findings show, the proclamation has brought about new demands on the way these women and children Charities and Societies operate be it in terms of financial, existential, sustainability or structural change. Though the proclamation creates an autonomous Agency for the CSO sector, allows income generation activities, and tries to curb harmful practices by Charities and Societies; it has strict funding source requirements, potential going out of operation of organizations and termination of employees. The study reveals that the Ethiopian Charities and Societies are most affected by the proclamation. A great challenge for them has been raising 90% of their funds locally; which has led to termination of activities, closure of organizations and termination of employment of staff. The absence of a tradition of giving financial support to human rights organizations, and the lack of the necessary skill and experience in generating funds from local sources are currently challenging the Charities and Societies

description: Die Untersuchung zeigt, dass Zeitarbeitnehmer nicht nur gezwungen sind, nachteilige Arbeitsbedingungen hinzunehmen, sie erleben im Gefolge ihrer Diskriminierung auch einen sozialen Statusverlust. Auf der Grundlage einer Gelegenheitsstichprobe von insgesamt 157 Interviews sowohl mit Leiharbeitnehmern und Stammmitarbeitern als auch Führungskräften aus Einsatzunternehmen, Personaldienstleistern und Personaldienstleisterverbänden werden die gebräuchlichen Kriterien für die soziale Einordnung abgeleitet. Die Zitate illustrieren auch die abweichende Behandlung von Leiharbeitnehmern und Motive hinter deren Benachteiligung.

Boundary terms of the Einstein-Hilbert action

description: The Einstein-Hilbert action for general relativity is not well posed in terms of the metric $g_{ab}$ as a dynamical variable. There have been many proposals to obtain an well posed action principle for general relativity, e.g., addition of the Gibbons-Hawking-York boundary term to the Einstein-Hilbert action. These boundary terms are dependent on what one fixes on the boundary and in particular on spacetime dimensions as well. Following recent works of Padmanabhan we will introduce two new variables to describe general relativity and the action principle with these new dynamical variables will turn out to be well posed. Then we will connect these dynamical variables and boundary term obtained thereof to existing literature and shall comment on a few properties of Einstein-Hilbert action which might have been unnoticed earlier in the literature. Before concluding with future prospects and discussions, we will perform a general analysis of the boundary term of Einstein-Hilbert action for null surfaces as well.

description: This research paper aims to identify the determinants of successful loan repayment performance in foreign owned investments in Ethiopia. Clear understanding of these factors would enable borrowers and financing banks to develop suitable marketing strategies, business models, processes, and pilot projects. To address the research objective, about 97total foreign direct investors who borrow from Commercial Bank of Ethiopia and Development Bank of Ethiopia. Purposive sampling methods were used. Questioners were distributed to 97 different respondents, from which 96 sample respondents replied appropriately to the questionnaire. Data gathered were analyzed based on these 96 responses using SPSS 20 software package. Descriptive statistics and explanatory research approaches were employed. All out puts were reported using frequency, correlation and multiple linear regression analysis results such as ANOVA and coefficient and regression results were used. The result indicates that sufficient loan size and flexible loan repayment period were the most statistically significant determining factors affecting Successful loan repayment performance. During inflation amount of loan default is high and if banks couldn't adjust repayment schedule during inflation the borrowers would unable to repay their loan efficiently and effectively and there might be loan default. Thus, if there is inflation, loan default may increase and borrower couldn't pay their loan successfully. Therefore, inflation has statistically significant and negative association with loan repayment. The study recommended that sufficient and larger amount of loan would enhance the investors' access to basic inputs and improved business management opportunities, which would lead to higher productivity, reduced per unit cost and increased income. Thus, lending institution should disburse sufficient amount of money equivalent to loan applied by the investors.

description: We examine the feasibility of detecting auroral emission from the potentially habitable exoplanet Proxima Centauri b. Detection of aurorae would yield an independent confirmation of the planet's existence, constrain the presence and composition of its atmosphere, and determine the planet's eccentricity and inclination, thereby breaking the mass-inclination degeneracy. If Proxima Centauri b is a terrestrial world with an Earth-like atmosphere and magnetic field, we estimate the power at the 5577Å OI auroral line is on the order of 0.1 TW under steady-state stellar wind, or ${\sim} 100 {\times}$ stronger than that on Earth. This corresponds to a planet-star contrast ratio of $10^{-6}-10^{-7}$ in a narrow band about the 5577Å line, although higher contrast ($10^{-4}-10^{-5}$) may be possible during periods of strong magnetospheric disturbance (auroral power $1-10$ TW). We searched the Proxima Centauri b HARPS data for the 5577Å line and for other prominent oxygen and nitrogen lines, but find no signal, indicating that the OI auroral line contrast must be lower than $2\times 10^{-2}$ (with power $\lesssim$ 3,000 TW), consistent with our predictions. We find that observations of 0.1 TW auroral emission lines are likely infeasible with current and planned telescopes. However, future observations with a space-based coronagraphic telescope or a ground-based extremely large telescope (ELT) with a coronagraph could push sensitivity down to terawatt oxygen aurorae (contrast $7\times 10^{-6}$) with exposure times of ${\sim} 1$ day. If a coronagraph design contrast of $10^{-7}$ can be achieved with negligible instrumental noise, a future concept ELT could observe steady-state auroral emission in a few nights.
