description: An influence of the phonon-phonon coupling (PPC) on the $β$-decay half-lives and multi-neutron emission probabilities is analysed within the microscopic model based on the Skyrme interaction with tensor components included. The finite-rank separable approximation is used in order to handle large two-quasiparticle spaces. The even-even nuclei near the r-process pathes at $N=82$ are studied. The characteristics of ground states, $2^+$ excitations and $β$-decay strength of the neutron-rich Cd isotopes are treated in detail. It is shown that a strong redistribution of the Gamow-Teller strength due to the PPC is mostly sensitive to the multi-neutron emission probability of the Cd isotopes.

description: We investigate an extension of the Standard Model containing two Higgs doublets and a singlet scalar field (2HDSM). We show that the model can have a strongly first-order phase transition and give rise to the observed baryon asymmetry of the Universe, consistent with all experimental constraints. In particular, the constraints from the electron and neutron electric dipole moments are less constraining here than in pure two-Higgs-doublet model (2HDM). The two-step, first-order transition in 2HDSM, induced by the singlet field, may lead to strong supercooling and low nucleation temperatures in comparison with the critical temperature, $T_n \ll T_c$, which can significantly alter the usual phase-transition pattern in 2HD models with $T_n \approx T_c$. Furthermore, the singlet field can be the dark matter particle. However, in models with a strong first-order transition its abundance is typically but a thousandth of the observed dark matter abundance.

Political Economy of International Education
Creators: name: Wu, Wenxi
Publisher: name: Critical Education
Year: 2022

description: As educational sectors and stakeholders are increasingly engaged in the practice of international education, there have been many discussions regarding two persisting issues with the practice, which can be summarised as Western-centrism and elitism. Applying concepts from the study of political economy, this paper analyses major political constraints underlying these two challenges. The paper suggests that the origin of these political constraints is a Western-dominated neoliberal world order, with powerful effects on the educational choices made by advantaged groups in non-Western societies. The analysis highlights a political-economic cycle based on the West’s export of educational products in exchange for human and economic capitals, which sustains the current ecology of international education. The paper also discusses possible ways to redress the political constraints for international education to be more inclusive and equitable. It concludes with notes on new challenges underway and their effects on the future directions of international education.

Renter Credit Programs: A Path Towards Reducing Concentrated Poverty in Chicago
Creators: name: Friesen Gehring, Karlyn
Publisher: name: Unknown
Year: 2021

description: This article proposes that renter credit programs should be implemented alongside current investment initiatives in low-income Chicago neighborhoods to address concentrated poverty. Renter credit programs invest cash credits in accounts tied to each tenant that can be redeemed after a set amount of time. Such programs have helped to strengthen community ties and increase financial stability for renters. The article considers historical and current drivers of poverty as well as the lasting impact that racial segregation has had on urban areas. It further discusses recommendations for implementing renter credit programs in Chicago based off of models that have found success in other U.S. cities. Finally, it proposes strategies for adapting the approach and overcoming its limitations, ending with current opportunities for collaborating with city development initiatives.

description: Stapp and others have proposed that reality involves a fundamental life process, or creative process. It is shown how this process description may be unified with the description that derives from quantum physics. The methods of the quantum physicist and of the biological sciences are seen to be two alternative approaches to the understanding of nature, involving two distinct modes of description which can usefully supplement each other, and neither on its own contains the full story. The unified view explains the major features of quantum mechanics and suggests that biological systems may function more effectively than would be expected on the basis of quantum mechanics alone.

description: A cylindrical tank wagon is a type of railroad freight car designed to transport chemicals, petroleum products, and other bulk liquids like oil.Itis a welded metal tank of cylindrical shape, placedhorizontally. Thisstudyaims analyze and identify the stress and fatiguedeformation of cylindricaloil tank wagon to minimize the deformation. The modelling of the cylindrical tank structure along with its simplified supporting frame of the wagons isdone by using the Solidworks 2013 software to show the geometry and the relevant component. After accomplishing the modellingon solidworks, itwasimportedinto the ANSYS v17.2 to analyze the stress, deformation and also FEMFAT was done to analysis the fatigue life of the tank. The meshing type for this research is Fine size meshing. All the properties material are applied. From the analysis of stress and fatigue which has been carried out through the deformation of the cylindrical tank in ANSYS and FEMFAT softwares, the material analysis was conducted and it yielded simulated result. The analysisincludes total deformation, stress, strain, and fatigue life, safety factorwasdoneusing ANSYS and also endurance limit and survival propability was done by FEMFAT softwares. The analysis of the simulation carried out throught changing the material has yielded the maximum deformations, standing at 0.0065458 Max carbone steel and at 0.003612 Max AISI A656 High StrengthAlloySteel, therefore the deformationof cylindrical tank reduce by 44.81 . FEMFAT software reveals that the selected material have greater endurance limit and survival probability, which mean the new material will be more resistant. So thisrecommendsthe application of the new materiel AISI A656 High StrengthAlloySteel for the analysis of cylindrical tank wagon material.

description: We define and study the class of positively finitely related (PFR) profinite groups. Positive finite relatedness is a probabilistic property of profinite groups which provides a first step to defining higher finiteness properties of profinite groups which generalize the positively finitely generated groups introduced by Avinoam Mann. We prove many asymptotic characterisations of PFR groups, for instance we show the following: a finitely presented profinite group is PFR if and only if it has at most exponential representation growth, uniformly over finite fields (in other words: the completed group algebra has polynomial maximal ideal growth). From these characterisations we deduce several structural results on PFR profinite groups.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: In this study Advanced oxidation process using Fenton reagents is considered for the application of textile dye-house wastewater treatment. A representative basic dye-house wastewater sample has been brought from K.K. Textile Factory and its characteristic is analyzed and the result shows that dye-house wastewaters, containing basic dyes, are hazardous to the environment since their COD & BOD values are higher than the free discharge limit values and also they are highly colored even at the lower dye concentration operation cases. After characterizing the wastewater, advanced oxidation of a Basic Blue 41 dyes using solar -Fenton treatment was investigated in batch experiments using Box–Behnken statistical experiment design and the response surface analysis. Dyestuff, H2O2 and Fe2+ concentrations were selected as independent variables in Box– Behnken design while color and COD removal were considered as the response functions. Color removal increased with increasing H2O2 and Fe2+ concentrations up to a certain level. High concentrations of H2O2 and Fe2+ adversely affected the color and COD removals due to hydroxyl radical scavenging effects of high oxidant and catalyst concentrations. Both H2O2 and Fe2+ concentration had profound effects on decolorization. Percent color removal was higher than COD removal indicating formation of colorless organic intermediate. The optimal H2O2 / Fe2+ / dyestuff ratio resulting in for the 99.75% color removal & 87.56% COD removal is found to be 1045mg/L / 52mg/L / 12mg/L ( 0, 0, -0.09 coded value).

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We modify the first laws of thermodynamics of a Reissner-Nordstrom anti-de Sitter black hole and a pure de Sitter space-time by the surface tensions. The corresponding Smarr relations are obeyed. The cosmological constants are first treated as fixed constants, and then as variables associated to the pressures. For the black hole, the law is written as $δE = T δS - σδA$ when the cosmological constant is fixed, where $E$ is the Misner-Sharp mass and $σ$ is the surface tension. Adopting the varied constant, we modify the law as $δE_0 = T δS - σ_{eff}δA +VδP$, where $E_0=M-\frac{Q^2}{2r_+}$ is the enthalpy. The thermodynamical properties are investigated. For the de Sitter space-time, the expressions of the modified laws are different from these of the black hole. The differential way to derive the law is discussed.

description: Integration with conventional electronics offers a straightforward and economical approach to upgrading existing superconducting technologies, such as scaling up superconducting detectors into large arrays and combining single flux quantum (SFQ) digital circuits with semiconductor logic and memories. However, direct output signals from superconducting devices (e.g., Josephson junctions) are usually not compatible with the input requirements of conventional devices (e.g., transistors). Here, we demonstrate the use of a single three-terminal superconducting-nanowire device, called the nanocryotron (nTron), as a digital comparator to combine SFQ circuits with mature semiconductor circuits such as complementary metal oxide semiconductor (CMOS) circuits. Since SFQ circuits can digitize output signals from general superconducting devices and CMOS circuits can interface existing CMOS-compatible electronics, our results demonstrate the feasibility of a general architecture that uses an nTron as an interface to realize a super-hybrid system consisting of superconducting detectors, superconducting quantum electronics, CMOS logic and memories, and other conventional electronics.

description: In this paper, we explore how teacher educator parents’ (TEPs) feelings about their choices for their children’s schooling and how these choices align or don’t with their professional values. We provide a nuanced look at the emotional elements of “school choice” and the delicate intersections of teacher educators’ personal and professional identities amid a neoliberal educational system that is grounded in choice. This paper illuminates TEPs’ cognitive dissonance and struggle through conflicted and emotional choices as they strive to live in ways that reflect their ideals, while parenting within a racist and stratified school system.

description: For space-based astronomical observations, it is important to have a mechanism to capture the digital output from the standard detector for further on-board analysis and storage. We have developed a generic (application- wise) field-programmable gate array (FPGA) board to interface with an image sensor, a method to generate the clocks required to read the image data from the sensor, and a real-time image processor system (on-chip) which can be used for various image processing tasks. The FPGA board is applied as the image processor board in the Lunar Ultraviolet Cosmic Imager (LUCI) and a star sensor (StarSense) (instruments developed by our group). In this paper, we discuss the various design considerations for this board and its applications in the future balloon and possible space flights.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: The main aim of this study was the use of enhanced coagulation method to reduce DBPs precursors from surfaces raw water source to control the formation of DBPs in drinking water. Jar test experiments were conducted to study the effectiveness of enhanced coagulation for removal of DBPs precursors from Legedadi reservoir, which is the major water supply to Addis Ababa Metropolitan the capital city of Ethiopia. In this study, for the removal of turbidity and organic matter polyelectrolyte, PACl, and alum were used. The performance of the three coagulants with varying dose level were assessed through treated water turbidity measurement and content of organic matter measured by surrogate parameters of total organic carbon value. These coagulants showed almost similar turbidity removal value. The results were indicated by TOC tested the optimum factorial combination of 1.75* optimum dose of PACl, which gave better resulting with optimum response values of 98.80 % organic matter removal efficiency, whereas Alum, and polyelectrolyte at 1.5*optimum dose showed optimum response value of 96.20, and 96.70 % organic matter removal efficiency respectively. The result showed that 84 % organic matter removal efficiency was obtained in conventional treatment, where as enhanced coagulation process showed an efficiency of 98.08 %. .Since organic matter is a large contributor in the formation of THMs, lower TOC values will likely indicate a lower potential for formation of disinfection by-products. This indicated that enhanced coagulation process is an effective means for removing organic matter present in drinking water if the coagulant dose and pH condition are adjusted to optimum condition. In general, TOC removal enhanced with increasing coagulant dose. However, further increases in coagulant dose beyond the optimal value had little negative effect on DBPs precursors' removal Key words: Enhanced Coagulation, Organic Matter (DBPs Precursor), Total Organic Carbon, Organic Carbon Removal, Addis Ababa, Legedadi Water Treatment Plant, Ethiopia
title: A just transition for UK oil and gas workers? Re-employment after job loss
Creators: name: Denyer, Kirsty Lindsay Reoch
Publisher: name: University of Reading
Year: 2023

description: The UK’s oil and gas industry is declining, in the context of net zero and depleting North Sea petroleum reserves. A ‘Just Transition’ is needed for its highly skilled workforce, who face reduced employment opportunities as their industry declines. This study explores the reality of a Just Transition – operationalised as ‘re-employment success’ (Wanberg, 2012, p377) – for workers experiencing job loss from the UK oil and gas industry. The study adopts the lens of structure and agency to understand the contextual and individual-level factors influencing their search for re�employment. Data for this qualitative study were collected via 37 semi-structured interviews with UK oil and gas workers with experience of seeking work after job loss, and industry stakeholders; and analysed using template analysis and abductive reasoning techniques. Analysis identified structural features of the UK oil and gas industry that influence access to replacement work: its boom and bust nature; its status of decline, evolution and uncertainty; and its unique culture. Within this context, individual-level resources which can enable an individual to act with agency were identified. These agentic resources were categorised as health, coping and job search resources. The importance of maintaining mental health by ‘managing the spiral’ highlights a dynamic process which can put at risk the very agentic resources needed to navigate the search for re-employment. Results were used to propose a model of acting with agency in the search for re-employment after job loss from the UK oil and gas industry. Findings were interpreted to mean that workers are not yet experiencing a Just Transition, due to low job security, lack of alternative employment opportunities and a lack of transition support. Achieving re-employment success is largely down to the individual worker, who requires a high level of agentic resources to cope with unemployment, and succeed in their search for work.

description: In the frame of a systematic study of excitation functions of deuteron induced reactions the excitation functions of the $^{133}$Cs(d,x)$^{133m,133mg,131mg}$Ba, ${134,132}$Cs and $^{129m}$Xe nuclear reactions were measured up to 40 MeV deuteron energies by using the stacked foil irradiation technique and $γ$-ray spectroscopy of activated samples. The results were compared with calculations performed with the theoretical nuclear reaction codes ALICE-IPPE-D, EMPIRE II-D and TALYS calculation listed in the TENDL-2014 library. A moderate agreement was obtained. Based on the integral yields deduced from our measured cross sections, production of $^{131}$Cs via the $^{133}$Cs(d,4n)$^{131}$Ba $\longrightarrow$ $^{131}$Cs reaction and $^{133}$Ba via $^{133}$Cs(d,2n) reactions is discussed in comparison with other charged particle production routes.

description: Nonequilibrium quasiparticles represent a significant source of decoherence in superconducting quantum circuits. Here we investigate the mechanism of quasiparticle poisoning in devices subjected to local quasiparticle injection. We find that quasiparticle poisoning is dominated by the propagation of pair-breaking phonons across the chip. We characterize the energy dependence of the timescale for quasiparticle poisoning. Finally, we observe that incorporation of extensive normal metal quasiparticle traps leads to a more than order of magnitude reduction in quasiparticle loss for a given injected quasiparticle power.

Creators: name: Jemil, Degife
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The goal of this study is analyzing and identifying the stresses on bolted rail joint due to the wheel load to predict and minimize failures caused. The three dimensional model has been developed on modeling package of CATIAV5R16. In CATIAV5R16, different components of wheel/rail assembly i.e. wheel, rail, joint, bars, nuts, bolts are created separately then all components are assembled, and create a complete model of wheel/rail assembly. Assembly model has created in assemble workbench of CATIA after individual component of joint had created on part work bench. After the assembly is accomplished on CATIA, it was imported in to the ANSYS v14.5 to analyze the stress caused by vertical load. The material properties of the rail and wheel are assumed to be same. All the material properties and boundary conditions are being applied to estimate fatigue stress. The analysis using the software ANSYS includes fatigue stress, fatigue life, von miss stresses, shear stress and Equivalent elastic strain. These values have been determined under the influence of axle load. The result obtained in this analysis is better stress values for rail joint assembled by the modified geometry than the existing joint bar. During the rail joint analysis Joint between the sleepers needed more attention than other parts, to reduce the problem related to the rail joint.

Automatic Railway Track Element Detection for East-West Route of Addis Ababa LRT
Creators: name: Melaku, Tegegne
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: In railways, regular maintenance and inspection of railway track is quiet commonly used approach to maintain an acceptable level of safety. Such approach is currently done in most railway companies; ERC will not be a different, using a very laborious, lengthy and manual work by visually inspecting and visiting test sites with a help of trained operators. Another approach is to have an automatic train control system where a train vehicle is completely controlled by a central control system without the need of human driver intervention since computer-aided machines are less likely to make mistakes than humans once carefully designed and installed. In this thesis, an automated system is presented which mitigates the said problem by detecting a railway track elements (such as fasteners) from a real railway track image taken by a digital camera that is mounted in the train. Based on the level of difficulty in the detection problem, suitable combinations of image processing and pattern recognition methods are applied to achieve high performance automated detection. The system is primarily based on the Viola-Jones object detection framework Viola and Jones, but it selects best new Haar wavelet-like features more convenient to the problem of Addis Ababa Light rail transit track fasteners detection. The performance of the system is improved by employing an appropriate image pre-processing and performance evaluation techniques. Accordingly, the system has managed to achieve a 94.6% detection rate of performance and has a failure rate of 0.11%.

description: Linoleic acid (C18:2∆9,12, LA) is an important metabolite with numerous essential functions for growth, health, and reproduction of organisms. It has long been assumed that animals lack ∆12‐desaturases, the enzymes needed to produce LA from oleic acid (C18:1∆9, OA). There is, however, increasing evidence that this is not generally true for invertebrates. In the insect order Hymenoptera, LA biosynthesis has been shown for only two parasitic wasp species of the so‐called “Nasonia group,” but it is unknown whether members of other taxa are also capable of synthesizing LA. Here, we demonstrate LA biosynthesis in 13 out of 14 species from six families of parasitic wasps by gas chromatography–mass spectrometry analysis using two different stable isotope labeling techniques. Females of the studied species converted topically applied fully 13C‐labeled OA into LA and/or produced labeled LA after feeding on fully 13C‐labeled α‐ d‐glucose. These results indicate that ∆12‐desaturases are widespread in parasitic Hymenoptera and confirm previous studies demonstrating that these insects are capable of synthesizing fatty acids de novo.

description: We study the physical mechanism of a major X-class solar flare that occurred in the super NOAA active region (AR) 12192 using a data-driven numerical magnetohydrodynamic (MHD) modeling complemented with observations. With the evolving magnetic fields observed at the solar surface as bottom boundary input, we drive an MHD system to evolve self-consistently in correspondence with the realistic coronal evolution. During a two-day time interval, the modeled coronal field has been slowly stressed by the photospheric field evolution,which gradually created a large-scale coronal current sheet, i.e., a narrow layer with intense current, in the core of the AR. The current layer was successively enhanced until it became so thin that a tether-cutting reconnection between the sheared magnetic arcades was set in, which led to a flare. The modeled reconnecting field lines and their footpoints match well the observed hot flaring loops and the flare ribbons, respectively, suggesting that the model has successfully "reproduced" the macroscopic magnetic process of the flare. In particular, with simulation, we explained why this event is a confined eruption-the consequent of the reconnection is the shared arcade instead of a newly formed flux rope. We also found much weaker magnetic implosion effect comparing to many other X-class flares

description: Rises in fuel prices and the continued pollution to the environment calls for a search to find cost effective and environmentally cautious methods of finding alternative fuels especially for industrial purposes while Ethiopia is spending around 2,000,000,000 birr/year for HFO. The treatment can be costly for the owners but a method such as anaerobic digestion can be used to treat the waste , minimize environmental pollution due to the use of fossil fuel at the same time minimize the financial cost. .This study focuses on optimization and upgrading of biogas from brewery waste and for boiler.. This research emphasizes on production of biogas from brewery waste and cow dung focusing on the optimization of process parameters such as temperature, HRT and TS for the maximal biogas production. Optimization of those variables was carried out by General factorial Design Expert software. Firstly, the characteristics of each of the two items were investigated in detail comparatively. The results obtained can be summarized as follows: Biogas volume and composition from brewery waste was 0.5L, 35% using 10 day, 35 ℃, 8%Ts and compared to Cow dung that yielded 3.9L, 70% using 10 day, 35 ℃, 8%Ts. Therefore, to increase the amount of methane composition and yield brewery waste and cow dung were mixed based on the recommendation from literature Total solid of 4%, 8% and 12%, Temperature at 25℃, 35 ℃, 50℃ and hydraulic retention time at 10, 15, and 20 days. From the experiment, all three parameters had significant effects on biogas volume and composition. The optimum conditions for maximizing the biogas yield and composition were 10 day, 35 ℃, 8%Ts a in which maximum biogas yield of 0.3 lit /gm. Out of which 60% is methane that is upgraded. The methane was upgraded to 81.4% methane using 25% caustic water absorption process. During upgrading the carbon dioxide content reduced below 22% and hydrogen sulphide was negligible during the production step. The upgraded methane gave calorific value of 6967.84Kcal/m3which has energy generating potential of 8.1kwh/m3. While this waste has a potential to generate 15,240.636 kwh/day of energy which could cover 16.6% of HFO consumption it can generate energy equal to12, 954.54 kwh/day and save 6,591,764.508 birr/year of its budget. In addition, there is a benefit for the environment and human health.
The Power of Place: An Analysis of Chicago's Neighborhood Opportunity Funds
Creators: name: Maranion, Danielle
Publisher: name: Unknown

description: To address growing inequalities, cities across the nation have turned to place-based funding strategies. In Chicago, the Neighborhood Opportunity Fund (NOF) provides grants to fund startup activity of local entrepreneurs in disinvested areas. Many of the contemporary challenges of cities today reflect the neoliberal assumptions of late twentieth-century policies. These solutions claim that market-driven processes, and not state intervention, are sufficient to promote positive, socially neutral development and growth. As one of the most segregated cities in the United States, Chicago stands as an example that these neoliberal policies exacerbate inequalities and actively exclude low-income, communities of color. With widespread neoliberal urban development, this paper seeks to show why municipal governments must consider realigning efforts to better empower local communities with the substantive tools and power to address neighborhood needs by using place-based strategies as a start to addressing racial inequalities.
title: Externally- vs. internally-derived H2O as control on reaction progress during high-pressure metamorphism

description:
The progress of metamorphic reactions at high-pressure is commonly limited by kinetics. Relatively low temperatures, absence of deformation, short timescales and particularly the paucity of fluid may hamper transformation, thereby promoting the preservation of lower-pressure assemblages at eclogite facies conditions. However, minute amounts of H2O can trigger the prograde breakdown of plagioclase to denser high-pressure assemblages. In the case of dry protoliths such as gabbro/granulite, H2O must be added to the system to cause metamorphism, for example via fluid infiltration. The ‘eclogitization’ of granitoids however can occur in a closed system due to the partial breakdown of igneous biotite. Both the addition of external H2O as well its liberation from biotite leads a localized increase in chemical potential (µH2O), causing H2O to be transported into nearby anhydrous minerals. If external H2O is added to metagranitoids at high pressure, it is mainly accommodated in phengite growing at the expense of K-feldspar. Upon decompression, such hydrated rocks would dehydrate, thereby causing fluid-assisted retrogression and loss of diagnostic eclogite-facies assemblages at lower pressure. By contrast, mafic eclogites have a limited capacity to store H2O in minor hydrous minerals such as amphibole. Even when fully saturated at high pressure, the crystallographically-bound H2O is insufficient for dehydration to occur during exhumation, thus favoring the preservation of garnet–omphacite-bearing assemblages. These mechanisms explain the discrepancy between peak pressures recorded in cogenetic mafic eclogites and orthogneisses observed in classic (U)HP terranes such as the Western Gneiss Region (Norway) and Dabie Sulu (China).

description: Social behaviors involving the interaction of multiple individuals are complex and frequently crucial for an animal's survival. These interactions, ranging across sensory modalities, length scales, and time scales, are often subtle and difficult to quantify. Contextual effects on the frequency of behaviors become even more difficult to quantify when physical interaction between animals interferes with conventional data analysis, e.g. due to visual occlusion. We introduce a method for quantifying behavior in courting fruit flies that combines high-throughput video acquisition and tracking of individuals with recent unsupervised methods for capturing an animal's entire behavioral repertoire. We find behavioral differences in paired and solitary flies of both sexes, identifying specific behaviors that are affected by social and spatial context. Our pipeline allows for a comprehensive description of the interaction between multiple individuals using unsupervised machine learning methods, and will be used to answer questions about the depth of complexity and variance in fruit fly courtship.

description:
Determining the origin of archaeological bronzes and their metal sources is one of the great desiderata of archaeologists. Answersing these questions is often difficult with archaeological and typological methods alone, which is why isotope and elemental compositions of metals have since become important components. While the methods for the analysis of copper are more or less straightforward, determining the origin of the tin sources is still limited. However, owing to the high inter-deposit variations of Sn isotope compositions, their analysis alone is not a raliable tool for determining the origin of tin in bronzes. Due to this fundamental limitations, recent works pursued a multi-isotope approach with Pb, Cu and Sn isotopes coupled with trace elements in two case studies searching for evidence of source mixing and/or recycling. This is beyond the mere provancing for sources, which in turn may help to reconstruct relationships between artefacts of different origins and reveal cultural and trade networks. The approach is now investigated on a much larger scale in our recent project. For this, about 300 blades of the Sögel and Wohlde type from the Nordic Early Bronze Age are to be isotopically and chemically analysed and compared with counterparts in southern central Europe and south-eastern Europe. Ultimately, the origin of the artefact types, their metal sources and their socio-economical entanglements will be disclosed, but at the same time a critical evaluation of analytical data will be undertaken against the background of metal/ore mixing and recycling.

description: Rail transport is an important mode of transport that can play significant role for economic development of a country. Especially, Electric system train driving technology has many advantages for environment protection and fuel consumption reduction. Train control system is a broad section in railway technology and has responsible for ensuring passenger's safety and security during their journey. It also improves travel comfort, providing real time multimedia information and access to social networks in stations or in motion. Accident in railway technology is very series issue. So, maintaining safety is the first precondition for railway transport. To have safe operation in railway technology, train operators need to put in place an effective and reliable train-to-ground and train to train communication technology. On the other hand, the commercial wireless technologies have been evolving from voice centric 2G systems (e.g. GSM) with limited data transmission capabilities to 4G broadband multiservice systems (LTE). This Thesis addresses how the innovative commercial wireless technologies can enhance the safety and reliability of AA-LRT. It introduces the implementation of long term evolution (LTE) technology to Addis Ababa light railway. Each train communicates with their neighbor trains through modern communication system called LTE. The information like train speed, train distance and location of the train obtain from the speed capturing system and GPS technology. This information processed through Microcontroller and the system alert for the train pilot even it takes action on the braking system if necessary. The system decreases the need to construct additional track in the city and reduce the probability of train collision. In this scenario, this paper investigates capacity and quality of service improvement; energy efficiency, mobility, passenger's safety and security and results obtained from simulations are presented.

description:
The up to 3.7 km-thick Moodies Group (~3.22 Ga) of the Barberton Greenstone Belt, South Africa and Eswatini, comprises some of the oldest well-preserved sedimentary strata on Earth, deposited within only a few million years in prodeltaic to alluvial settings, with a dominance of tidal deltas and coastal plains. Moodies Group strata consist of polymict conglomerates, widespread quartzose, lithic and arkosic sandstones, siltstones, shales, and rare BIFs and jaspilites, all interbedded with tuffs and several lavas. They preserve abundant sedimentary structures and represent a very-high-resolution record of Paleoarchean surface conditions and processes. Widespread microbial mats, early-diagenetic vadose alteration zones and tidal rhythmites allow to investigate the environmental conditions under which bacterial life spread on early Earth. The ICDP Barberton Archean Surface Environments (BASE) Project drilled November 2021 to June 2022 eight inclined boreholes of 300-450 m length each through steeply inclined or overturned Moodies Group strata; the unweathered and continuous core record was complemented by sampling in three several-km-long tunnels and by detailed surface mapping. Two to three rigs operated concurrently, delivering twenty to sixty m of high-quality core daily, processed in a large, publicly accessible hall adjacent to the museum in downtown Barberton. An exhibition provided background explanations for visitors and related this fundamental geoscience research project to the recently established Barberton-Makhonjwa Mountains World Heritage Site.
