description: It is shown that tunneling rates can be defined in terms of a false-vacuum effective action whose reality and convexity properties differ from those of the corresponding groundstate functional. The tunneling rate is directly related to the false-vacuum effective action evaluated at an extremal "quantum bounce". The Nielsen identities of the false-vacuum functional ensure that the rate remains independent of the choice of gauge-fixing. Our results are nonperturbative and clarify issues related with convexity and radiative corrections.

description: The timed pattern matching problem is formulated by Ulus et al. and has been actively studied since, with its evident application in monitoring real-time systems. The problem takes as input a timed word/signal and a timed pattern (specified either by a timed regular expression or by a timed automaton); and it returns the set of those intervals for which the given timed word, when restricted to the interval, matches the given pattern. We contribute a Boyer-Moore type optimization in timed pattern matching, relying on the classic Boyer-Moore string matching algorithm and its extension to (untimed) pattern matching by Watson and Watson. We assess its effect through experiments; for some problem instances our Boyer-Moore type optimization achieves speed-up by two times, indicating its potential in real-world monitoring tasks where data sets tend to be massive.

description: Lapis Lazuli is one of the oldest precious stone, being used for glyptic as early as 7000 years ago: jewels, amulets, seals and inlays are examples of objects produced using this material. Only few sources of Lapis Lazuli exist in the world due to the low probability of geological conditions in which it can form, so that the possibility to associate the raw material to man-made objects helps to reconstruct trade routes. Since art objects produced using Lapis Lazuli are valuable, only non-destructive investigations can be carried out to identify the provenance of the raw materials. Ionoluminescence (IL) is a good candidate for this task. Similarly to cathodoluminescence (CL), IL consists in the collection of luminescence spectra induced by MeV ion (usually protons) irradiation. The main advantage of IL consists in the possibility of working in air while measuring simultaneously the composition of major and trace element by means of complementary Ion Beam Analysis techniques like PIXE or PIGE (Particle Induce X-ray or Gamma-ray Emission). In the present work a systematic study of the luminescence properties of Lapis Lazuli under charged particles irradiation is reported. In a first phase a multi-technique approach was adopted (CL, SEM with microanalysis, micro-Raman) to characterise luminescent minerals. This characterisation was propaedeutic for IL/PIXE/PIGE measurements carried out on significant areas selected on the basis of results obtained previously. Criteria to identify provenance of Lapis Lazuli from four of the main sources (Afghanistan, Pamir Mountains in Tajikistan, Chile and Siberia) were proposed.

description:
Mantle metasomatism largely controls the physical and chemical properties of the lithospheric mantle and exerts control over the genesis of kimberlitic magmas and diamond formation. In this context, garnet xenocrysts from kimberlites are fundamental for decoding metasomatic events in the lithospheric mantle and to decipher the variation in rock types with depth. However, dating mantle lithologies and processes is complicated by high ambient temperatures that allow the equilibration of most isotopic systems up to the time of kimberlite eruption.

In this study we investigate garnet xenocrysts from the ~376 Ma V. Grib kimberlite, Russia to evaluate the potential of garnet for dating metasomatic events in the subcontinental lithospheric mantle. Based on major and trace element compositions and REE patterns, harzburgitic, wehrlitic, lherzolitic (4x) and megacrystic garnet xenocrysts are distinguished.

Our preliminary data indicates that garnet can record the ages of different metasomatic events. Garnet from harzburgitic and lherzolithic lithotypes indicate at least 30 myr of mantle metasomatism prior to kimberlite eruption. This age spread reflects distinct metasomatic events, but partial resetting of the U-Pb isotope system also has to be considered.
Inverse Mellin Transformation of Continuous Singular Value Decomposition: A Route to Holographic Renormalization

description: We examine holographic renormalization by the singular value decomposition (SVD) of matrix data generated by the Monte Carlo snapshot of the 2D classical Ising model at criticality. To take the continuous limit of the SVD enables us to find the mathematical form of each SVD component by the inverse Mellin transformation as well as the power-law behavior of the SVD spectrum. We find that each SVD component is characterized by the two-point spin correlator with a finite correlation length. Then, the continuous limit of the decomposition index in the SVD corresponds to the inverse of the correlation length. These features strongly suggest that the SVD contains mathematical structure the same as the holographic renormalization.

description:
Meteoric 10Be is introduced to the ground surface as fallout from cosmic-ray production in the atmosphere, while 9Be is a trace element released by mineral weathering.  The 10Be/9Be ratio in soil and sediment is therefore used to infer the rate of primary mineral weathering over the timescale of 10Be accumulation, typically 103-105 y.  Although beryllium is retentive in soils, a small fraction is released to groundwater.

In carbonate landscapes, groundwater beryllium accumulates in cave speleothem, and can be used to track changes in soil 10Be/9Be over time.  Independently dated speleothem offer a novel way to monitor weathering rate at a single site over glacial-interglacial timescales.  Here, we present a 10Be/9Be record from Soreq Cave, Israel, which we interpret as a weathering history of beryllium-bearing silicates (primarily feldspar) in the overlying terra rossa soil derived from loess.  Results show that silicate weathering rates vary 2-fold with temperature over the past ~175 ky, from a low of 2-3 t km-2 y-1 during cool glacials to a high of 5-6 t km-2 y-1‑during warm interglacials.  Considered as an Arrhenius relationship, the weathering rate indicates an activation energy of 97 ± 16 kJ/mol, similar to other field-based estimates for feldspar weathering.

Although the beryllium isotopic record in speleothem is likely to be complicated by factors such as changing vegetation and soil depth, our initial work shows promise as a proxy for local soil weathering rates through time, offering a new method for quantifying relationships between climate, soils, and landscape evolution.
In-medium properties of the phi meson with phi N resonant contributions

description: Nuclear production experiments report missing absorption processes of the in-medium phi meson. Contributions arising from the K-bar K cloud have already been widely studied, and therefore we investigate the phi-meson properties in cold nuclear matter with the additional inclusion of resonant phi N interactions. Two models are considered which dynamically generate N*-like states close to the phi N threshold. We find that these states, together with the non-resonant part of the amplitude, contribute to the phi self-energy with the same order of magnitude as the K-bar K effects. At non-vanishing nuclear density, both models lead to an additional in-medium broadening of the phi, up to around 50 MeV. Furthermore, at least one of the models is compatible with a mass shift to lower energies of up to 35 MeV at threshold and normal matter density. Finally, a double-peak structure appears in the spectral function due to the mixing of resonance-hole modes with the $ϕ$ quasi-particle peak. These results converge into the direction of the experimental findings.

description:
In the Chilean Atacama Desert, alternation of lacustrine evaporites and diatomites suggest that hyper-aridity has prevailed since the early Miocene, but was interrupted by recurring pluvial phases. Changes in lacustrine deposition, however, can be either climate- or tectonically-driven, which challenges a unique interpretation. Here, we demonstrate that an isotope model-data approach combining triple oxygen and hydrogen isotope data of paleo-lake water derived from gypsum hydration water with the Craig-Gordon evaporation model can provide quantitative information on local hydroclimate conditions in the past Atacama Desert.

We analyzed the isotope composition (δ17O, δ18O, δ2H) of structurally bonded water extracted from lacustrine and marine gypsum deposits in the Atacama Desert of Late Miocene and Pleistocene age, respectively. We used a Monte Carlo simulation to obtain the best-fit solution of input variables of the Craig-Gordon equation – notably, relative humidity, the isotope composition of source water and atmospheric water vapor – through isotope data of multiple gypsum samples from a single unit of the paleo-lacustrine formations. Gypsum ages were obtained by U-Pb dating.

Our results demonstrate that a generally more humid climate persisted over northern Chile 8.9 Ma ago, caused by distal vapour advection with significant rainout along the vapour advection pathway. The regional atmospheric circulation likely changed as a result of an overall weaker sub-tropical subsidence over the Miocene SE Pacific Ocean. Marine lagoon gypsum with an age of 1.8 ± 0.2 Ma were deposited under near-similar hyper-arid conditions in comparison to the present-day coastal climate.

description: We study a Gaussian matrix function of the adjacency matrix of artificial and real-world networks. In particular, we study the Gaussian Estrada index---an index characterizing the importance of eigenvalues close to zero. This index accounts for the information contained in the eigenvalues close to zero in the spectra of networks. Here we obtain bounds for this index in simple graphs, proving that it reaches its maximum for star graphs followed by complete bipartite graphs. We also obtain formulas for the Estrada Gaussian index of Erdős-Rényi random graphs as well as for the Barabási-Albert graphs. We also show that in real-world networks this index is related to the existence of important structural patterns, such as complete bipartite subgraphs (bicliques). Such bicliques appear naturally in many real-world networks as a consequence of the evolutionary processes giving rise to them. In general, the Gaussian matrix function of the adjacency matrix of networks characterizes important structural information not described in previously used matrix functions of graphs.

description: The Health facilities of any region in the country have a responsibility for establishing of reliable, cost-effective, and sustainable pharmaceutical supply chains that will capable for meeting the demand of its local area people and patients, likely wise all H/Facilities found in the Arsi Zone are responsible to avail and store pharmaceutical for preventing and curative health services. To accomplish different health activities the health facilities, need enough warehouse space for storage of supplies. Unlike other products pharmaceutical supplies need standard warehouse for minimizing of wastages due to poor storage management activities any pharmaceutical warehouse components are arranged to provide cost-effective and efficient product flows to clinical users. These components comprise 1) the warehouse facility; 2) the material handling equipment & layout; 3) warehouse internal operations or activities 4) receiving and issuing of orders from suppliers or users. The total population of H/centers found under the ZHD is 98 and the sample size was 40 for this study. Primly all Zonal H/centers were stratified by 26 woredas and H/centers found under the woreda town were selected for assessment purposely being they have high volume patient and supply consumptions. The researcher believes that the impact of poor storage practices & shortages of space in high volume H/centers were sever than the rest nearby H/Centers. The rest 14 were selected in random probability methods. (40% X 96). The research method for gathering of information employed was a mix of interviewing to store managers and relevant management members by using the standard questionaries' which was categorized in to six major sections. In addition to this I observe the actual operation practices inside warehouses during my selfpresentation of questioners to the store heads like availability of pallets, shelves, recording & documentation practices and finally about space adequacy status. The total sum of the recommendations was then presented to AAUSC for academic fulfillment and the statement of my recommendations will be my next phase of effort to realize this research in to practices
A STUDY ON WORKING CAPITAL MANAGEMENT WITH REFERENCE TO MICRO POLYESTER LAMINATION

description: This study aims to analyze the working capital management practices at Micro Polyester Lamination and their impact on the company's financial performance. The methods employed include a detailed review of the company's financial statements, ratios related to working capital management (such as the current ratio, quick ratio, and cash conversion cycle), and comparison with industry benchmarks. The results show that while the company maintains a relatively stable working capital, inefficiencies in inventory management and accounts receivable cycles affect its liquidity and operational flexibility. A strong correlation was found between working capital management practices and profitability, where the efficient management of current assets and liabilities contributed to a better return on assets. The conclusion highlights the need for Micro Polyester Lamination to focus on optimizing inventory turnover and accelerating receivables collection to improve its cash flow and operational efficiency. Additionally, the study suggests that better management of working capital could lead to enhanced profitability and competitiveness in the market.
The Minimum Wage and Means-Tested Benefits: Raising the Wage and Raising the Threshold
Creators: name: Rippel, Kaitlyn
Publisher: name: Unknown
Year: 2021

description: This article argues that in the current and ongoing political battle to raise the minimum wage, we must account for the impacts on means-tested benefits. Beginning with a look at how raising the federal minimum wage to $15/hour would improve the financial conditions for people whose income falls at the poverty line, it tackles the arguments against raising the minimum wage and explores means-tested benefits by looking at marginal tax rates and income thresholds. It further engages concerns that raising the minimum wage will negatively impact employment by discussing the Work Opportunity Tax Credit. This article is not an exhaustive analysis of the fight to raise the minimum wage, but it paints a picture of where the movement is headed and what we need to keep in mind on the way there.

description:
Reaction rims contain a wealth of information that can be used to decipher the P-T-t-X history of metamorphic and metasomatic rocks. One of the most important parameters that controls reaction rim growth dynamics is the presence of volatiles, which can affect rim thicknesses, phase stabilities and the development of rim microstructures.

We performed reaction rim growth experiments to investigate net-transfer reactions in both “dry” and “wet” systems. Reaction rims were produced between single crystals of quartz and periclase in an internally heated pressure vessel (IHPV) at 0.3-0.4 GPa and 1100-1300 °C for 66 h to 168 h. In “wet” experiments, a ppm amount of water was introduced by pre-annealing periclase single crystals at water saturated conditions, which is gradually released during rim growth experiments.

First results indicate the formation of single enstatite or forsterite and double enstatite-forsterite reaction rims in the “dry” and “wet” systems respectively. When water-doped periclase is used as a reactant, reaction rim growth rates increase from 10-18.23±0.18 to 10-17.67±0.03 m2/s at 1100 °C and from 10-16.95±0.06 to 10-16.16±0.01 m2/s at 1200 °C. In experiments that were entirely anhydrous, no reaction rim formed at all. These observations suggest that water may act as a catalyst and that a certain fluid threshold is needed to initiate metamorphic re-equilibration.

These findings imply that reaction rims may be used to discriminate between kinetically “dry” and “wet” systems and have thus the potential to monitor the presence of extremely small amounts of water during metamorphic reactions in natural systems.

description: We propose a model solely based on actin treadmilling and polymerisation which describes many characteristic states of actin wave formation: spots, spirals and travelling waves. In our model, as in experiments on cell recovering motility following actin depolymerisation, we choose an isotropic low density initial condition; polymerisation of actin filaments then raises the density towards the Onsager threshold where they align. We show that this alignment, in turn, destabilizes the isotropic phase and generically induces transient actin spots or spirals as part of the dynamical pathway towards a polarized phase which can either be uniform or consist of a series of actin-wave trains (flocks). Our results uncover a universal route to actin wave formation in the absence of any system specific nonlinear biochemistry, and it may help understand the mechanism underlying the observation of actin spots and waves in vivo. They also suggest a minimal setup to design similar patterns in vitro.

Inventory and Inspection Guideline for Railway Bridges
Creators: name: Addisu, Desalegne
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Due to the substantial role of bridges in transportation network and in accordance with the limited fund for bridge management, remedial strategies have to be prioritized. A conservative bridge assessment will result in unnecessary actions, such as costly bridge strengthening or repairs. On the other hand, negligence and delayed action of bridge maintenance may lead to heavy future costs or degraded assets. The accuracy of decisions developed by any manager or bridge engineer relies on the accuracy of the bridge assessment which emanates from well-established bridge Inventory and Inspection. A high degree of accurate Bridge Database is only maintained if the bridge Inventory and Inspection is carried out using well-established guideline. If bridge Inventory and Inspection tasks are not performed for all bridges without having a well-established guideline, frequent collapse would occur at the same time in many parts of the county and would provoke social and political chaos. As a new government corporate the Ethiopian Railway Corporation needs to start the bridge asset management by inventory and inspecting of its new assets. To perform this, sustainability of well-established bridge Inventory and Inspection guideline should be established. Therefore; the main goal of this research is study preparation of Inventory and Inspection Guideline for Railway Bridges in Ethiopia by adapting the practice in similar sources. In this research Inventory and Inspection Guideline for Ethiopian railway bridges is studied from the experience of different countries, bridges administration authorities ERA, AACRA, manuals and others relevant sources, and a seed for Rail Bridge Management System established.

description: We use radial velocities from spectra of giants obtained with the WIYN telescope, coupled with existing chemical abundance measurements of Na and O for the same stars, to probe the presence of kinematic differences among the multiple populations of the globular cluster (GC) M13. To characterise the kinematics of various chemical subsamples, we introduce a method using Bayesian inference along with an MCMC algorithm to fit a six-parameter kinematic model (including rotation) to these subsamples. We find that the so-called "extreme" population (Na-enhanced and extremely O-depleted) exhibits faster rotation around the centre of the cluster than the other cluster stars, in particular when compared to the dominant "intermediate" population (moderately Na-enhanced and O-depleted). The most likely difference between the rotational amplitude of this extreme population and that of the intermediate population is found to be $\sim$4 km s$^{-1}$, with a 98.4% probability that the rotational amplitude of the extreme population is larger than that of the intermediate population. We argue that the observed difference in rotational amplitudes, obtained when splitting subsamples according to their chemistry, is not a product of the long-term dynamical evolution of the cluster, but more likely a surviving feature imprinted early in the formation history of this GC and its multiple populations. We also find an agreement (within uncertainties) in the inferred position angle of the rotation axis of the different subpopulations considered. We discuss the constraints that these results may place on various formation scenarios.

Determination of Biokinetic Coefficients of Distillery Wastewater Using Activated Sludge Process
Creators: name: Werku, Teshome
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Distilleries are among the existing industry which produces high effluent volume characterized with high temperature, low PH, very high COD and BOD, which is potentially dangerous to the environment if it is discharged without effective treatment. Therefore, this study is conducted to determine kinetic data which is crucial for effective treatment of this high volume distillery effluent using activated sludge process. In this thesis work samples for the laboratory experiment were taken from Metehara sugar factory, with the following characteristic pH 3.8 – 4.5, COD 92,000 mg/L, BOD 45,410 mg/L, TS 49,950 mg/L, temperature 89 – 98 oC , Nitrogen 1150 mg/L and phosphorous 4100mg/L. In the determination of the kinetic coefficients, Michaelis-Menten relation for continuous process was used. Chemicals which are used in this experiment are ATH to avoid nitrification, KOH to absorb CO2and Na (OH) to maintain pH. During the study, performance of a laboratory-scale biological treatment unit for the distillery waste was evaluated and the kinetic parameters for the activated sludge process were determined. A laboratory-scale treatment unit comprising aerobic digester and final clarifier was used for this purpose. The treatment unit was operated continuously for 270 days by varying the hydraulic retention times from 2 to 9 days. The biological oxygen demand (BOD) of the influent and effluent and the mixed liquor volatile suspended solids of the aeration tank were determined at various detention times to generate data for the kinetic coefficients. The kinetic coefficients k (maximum substrate utilization rate), Ks(half velocity constant), Y (cell yield coefficient), and Kd (decay coefficient) were found to be 4.46 per day, 534 mg/L, 0.714, and 0.038 per day, respectively, based on BOD and MLVSS in the reactor. These coefficients used for the design of reactor volume and sludge handling facility for activated sludge process

description:
Orogenic Sb-Au ore bodies of deposits near Pezinok (Malé Karpaty Mts., Slovakia) are hosted in metamorphosed black shales in amphibolites. The ore bodies contain parageneses with various Sb sulfides, sulfoxides, and oxides. Given the variable mineral assemblages, the deposit serves as a model to understand the behaviour of Sb isotopes from initially reducing to an evolving oxidizing system at µm-scales. Here we determined the stable isotope composition (δ123Sb) of antimony minerals in-situ using a deep UV-femtosecond laser ablation system coupled with MC-ICP-MS [1]. The precision of analyses was <0.1 ‰ and all analysis were reported relative to NIST 3102a.

Polished sections, containing assemblages of successively precipitated antimony minerals, show an isotopic range from -0.2 to +0.8 ‰. Stibnite, which is the most abundant mineral, shows an isotopic variation of around 0.35 ‰ (median = -0.2 ‰) that is generally lighter than δ123Sb of kermesite (0.1 ‰), valentinite-senarmontite (~0.5‰), and schafarzikite (~0.8 ‰). This isotopic relationship is consistent with textural and thermodynamic observations, indicating earlier formation of stibnite, followed by kermesite, valentinite-senarmontite, and schafarzikite formation during decreasing temperatures and increasing fO2. The large isotopic variation within and between different minerals can be explained by a Rayleigh fractionation model with enrichment of 123Sb in the residual fluid and in successively later formed minerals. Therefore, the results of this study suggest that in-situ δ123Sb values could be a promising tool to understand the evolution of orogenic Sb-Au deposits in space and time.

description: Recent experiments (G. Ariel, et al., Nature Comm. 6, 8396 (2015)) revealed an intriguing behavior of swarming bacteria: they fundamentally change their collective motion from simple diffusion into a superdiffusive Lévy walk dynamics. We introduce a nonlinear non-Markovian persistent random walk model that explains the emergence of superdiffusive Lévy walks. We show that the alignment interaction between individuals can lead to the superdiffusive growth of the mean squared displacement and the power law distribution of run length with infinite variance. The main result is that the superdiffusive behavior emerges as a nonlinear collective phenomenon, rather than due to the standard assumption of the power law distribution of run distances from the inception. At the same time, we find that the repulsion/collision effects lead to the density dependent exponential tempering of power law distributions. This qualitatively explains experimentally observed transition from superdiffusion to the diffusion of mussels as their density increases (M. de Jager et al., Proc. R. Soc. B 281, 20132605 (2014)).

title: Deriving basin-wide erosion/denudation rates of basaltic rocks using cosmogenic Kr isotopes, vulcanic complex Vogelsberg, Germany

description:
The Vogelsberg area located in Hessen, Germany, comprises the largest contiguous volcanic complex in Central Europe, covering an area of about 2300 km². After volcanic activity ceased during the Mid Miocene, the complex was subject to extensive erosion and weathering. Fluvial erosion has shaped the area, which is now characterised by Pleistocene valleys and a radial river system exposing primitive alkali basalts and basanites. The inference of time-integrated erosion rates from regularly measured cosmogenic nuclides (e.g. 10Be, 26Al) remains challenging in such an environment due to the apparent mafic and thus quartz-poor composition of the local bedrock. However, the application of cosmogenic Kr isotopes on the weathering-resistant mineral zircon provides a novel tool to infer basin-wide denudation rates from quartz-poor lithologies. In our project, we aim to exploit the advantage of the applications of Kr and sample zircons from sediments of six streams radially draining the Vogelsberg. After zircon purification, these samples will be measured at the Cologne Noble Gas Mass Spectrometer to quantify Kr concentrations in these samples and to assess the time-integrated erosion patterns shaping the volcanic complex.

description:
Nowadays, applications of nanomaterials increasingly demand for monodisperse nanoparticles (NPs), since their defined properties form the basis for a wide range of applications. Gold NPs are of special interest due to their fascinating optical properties related to localized surface plasmons. This plasmonic behavior is highly responsive to extrinsic factors (physical-chemical environment, temperature, interactions of particles, stabilizing agent, etc.) and their morphology (size, shape, quality of surface). We present a three-step seed mediated synthesis for highly monodisperse single crystalline Au NPs stabilized by hexadecylpyridinium chloride (CPC) in variable sizes (24-90 nm) with an adjustable ratio of the cubic and octahedral facets. [1] This synthesis thus circumvents the common reproducibility drawbacks of CTAB-dependent syntheses. [2] The effect of the additive KBr and reducing agent ascorbic acid on shape and growth kinetics was systematically investigated and an explanation for the switching of the Au NPs morphology from cubic to octahedral is provided. The plasmonic response of individual particles and their assemblies is demonstrated using spatially resolved EELS to show the optical behavior of the particles, which is far superior to that of lithographically fabricated Au nanostructures. [3] These particles may then be used to assemble mesocrystals. Such superstructures of crystallographically aligned NPs may lead to strong directional and additional novel collective properties that cannot occur in any other structure of the same size range.

description: We study analytically and experimentally certain symplectic and time-reversible N-body integrators which employ a Kepler solver for each pair-wise interaction, including the method of Hernandez & Bertschinger (2015). Owing to the Kepler solver, these methods treat close two-body interactions correctly, while close three-body encounters contribute to the truncation error at second order and above. The second-order errors can be corrected to obtain a fourth-order scheme with little computational overhead. We generalise this map to an integrator which employs a Kepler solver only for selected interactions and yet retains fourth-order accuracy without backward steps. In this case, however, two-body encounters not treated via a Kepler solver contribute to the truncation error.

Rail Crack Analysis with Inspection and Maintenance Plan at Transition Section Between Bridges and Embankments

Year: 2016

description: Since railway is considered as optimal solution for the quickly growing transportation demand its design, construction and maintenance should get proper attention. In rail route design, we may need (be forced) to consider bridges and tunnels to pass obstacles (especially in countries like Ethiopia). And emphasis must be given for transition section like between bridges and embankments because when the railway route pass from embankment to bridge or vice versa the track bed stiffness (modulus) varies causing abrupt change in vertical deflection which intern leads to frequent high vertical force exerted on the track structure, that cause more frequent damage to the track systems. So, this study gives emphasis to the damage on rail occurring at this transition section (specifically from embankment to bridge or vice versa). The study uses ABAQUS and FRANC 3D software to determine the stress that occurs on the rail at the transition section and the crack size (level of damage) respectively together with analytical equation to get some important parameters used for the analysis. Accordingly, the analysis results shows that due to the track bed stiffness difference the crack will be 3.5 mm at the rail base and 2.5 mm at the rail head. However, in depth experiments show that the rail can serve as long as the gap due to the crack is up to 70mm. Therefore, the probability of derailment happening is small. Even if the derailment happening probability is less, as cracks can propagate with increased number of cycles, the rail should be inspected and maintained frequently. From the numerical investigation, the inspection frequency of the rail at the transition section should be four times in a year (every three month). Finally, the conclusions of the research are presented with recommendations for further research by adding other factors that affect stiffness at transition sections.
title: Mineralogy and Leaching of Steel Slag (BOF/LD/Converter steel slag)

description:
Integrated steelworks produce steel from iron-ore. Co-produced are vast amounts of slags in the Blast Furnace process (~200-250 kg slag/ton of metal) and Basic Oxygen Furnace (BOF) process (~100 kg slag/ton of steel). Whereas BF-slag is in high demand for cement use, BOF-slag addition to cement doesn’t create synergy, despite mineralogical similarity.

BOF slag mineralogy can be predicted using thermochemical modelling for the multicomponent system CMAFfSP, using FactSage, and petrological observations of BOF slag confirm phenocrysts of Magnesio-Wuestite (Liquidus-phase) followed by alpha-C2S, in a groundmass of co-crystalizing Wuestite, Srebrodolskite (C4AF), C2S and lime. Incorporation of minor constituents (Ti, V, Cr) occurs in Wuestite (Cr) and C2S (V) and C4AF (V, Ti), but cannot be predicted for lack of solid solution models. Cr and V can cause leaching concerns for slag applications.

Studying hydration reactions on finely ground BOF slag indicates that hydrogarnet, hydrotalcite, portlandite and CSH-gel tend to form as product and that all primary slag phases contribute in the reaction. The leaching of Vanadium is pH-controlled during C2S dissolution.

Application of BOF slag as secondary raw material requires adequate characterization. Grinding BOF slag to cement-fineness can produce a high-strength binder, however, requiring the aid of specific additives.

description: Technological development has resulted in a boundary free digital world. This development has resulted in transaction through virtual money instead of real ones, e-ticketing is mostly used system for such transactions. But AA LRT uses weak and unreliable ticketing system which is called paper ticketing. The thesis system makes use of barcode for verification and identification of the user. A unique barcode will be generated for each customer that is registered to the system. Using this barcode, the customer will be able to make transactions, which is an automated fare collection. This system solves all the drawback of the manual ticketing system which currently happened in AA LRT. Two dimensional bar codes could provide for more complex ticket types. The barcode based card number of the user is used which provides the information of the user. This system provides an efficient way of travelling while maintaining the security. This system is implemented using Visual studio 2013 development environment, C# programing language and database (SQL server). In the implementation of this system it requires barcode scanner with gate controller which scans the profile from the ID card, then sends to the database to check the validation and desktop application to register new customers profile and amount paid, generate the barcode based ID card, update customer balances and configured the stations. Finally, the system software is successfully developed.
