description: Anxiety and depression disorders show high prevalence rates, and stress is a significant risk factor for both. However, studies investigating the interplay between anxiety, depression, and stress regulation in the brain are scarce. The present manuscript included 124 law students from the LawSTRESS project. Anxiety and depression symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS), and psychosocial stress was induced with the imaging stress paradigm ScanSTRESS. Anxiety, but not depression scores, were significantly related to neural stress responses in a striato-limbic cluster. Moreover, relative to women, men showed stronger associations between anxiety scores and activation in striatal and temporal clusters. A bifactor model of the HADS suggested a general factor characterized by tension, nervousness, and cheerlessness, which was associated with activation changes in a similar but more circumscribed cluster than anxiety. In the LawSTRESS project, the HADS was assessed at five sampling points (1 year, 3 months, 1 week prior exam, 1 week, and 1 month thereafter), and thus an exploratory trajectory analysis could be performed. It confirmed the relationship between anxiety scores and striatal stress responses at baseline but revealed no predictive value of the neural measure across the sampling points. Our results suggest that—in healthy young participants—neural acute psychosocial stress responses in striato-limbic structures are associated with anxiety, supporting the assumption that these regions are related to individual differences in vulnerability to stress-related disorders. A correlation with depression scores could not be found, and possible explanations are discussed.

description:
Analysis of Au in geological materials has been proven useful for understanding geological processes related to the formation of various Au-rich ore deposits. However, the Au concentration in the source rocks is extremely low and the methodologies allowing analysis at sub-ng/g levels are time-consuming, costly and generally involve handling of dangerous chemicals. Here we present a new, faster, cheaper and safer method for low Au concentration analysis by Laser-Ablation Inductively-Coupled-Plasma Mass-Spectrometry (LA-ICP-MS) of pressed-powder-pellets (PPP), which has been developed in the Laboratory for Environmental and Raw Materials Analysis (LERA) at Karlsruher Institut für Technologie (KIT). Fine instrumental tuning for key parameters such as ICP-MS sample gas flow, torch position, RF power, laser frequency, ablation style and laser gas flow allows us to increase the Au sensitivity while keeping oxide production low. Indeed, the latter is critical when analysing low concentration Au samples as the ICP-MS analysis is generally impaired by Ta181O16 and the Hf180O16H1 interferences. Reducing the oxides allows the PPP-LA-ICP-MS method for better quantification and correction of these interferences. The new method improves the detection limit down to 0.05-0.1 ng/g Au. Routine analysis of reference materials shows that Au analysis by PPP-LA-ICP-MS is both accurate and precise. This contribution highlights that the method is suitable for investigating Au distribution and behaviour in Au depleted rocks.

description:
TRR170-DB (https://planetary-data-portal.org/) is a re3data (r3data.org) referenced data repository that stores machine-readable replication datasets of the collaborative research center ‘Late Accretion onto Terrestrial Planets’ (TRR 170) and from other institutions in the planetary science community. The TRR170-DB framework aligns their data storage with the FAIR (Wilkinson et al., 2016) data life cycle as promoted by the German National Research Data Infrastructure Initiative (www.nfdi.de) and various national and international funding agencies and initiatives. The TRR170-DB repository will be permanently hosted by Freie Universität Berlin, which ensures long-term preservation of, and access to TRR170-DB’s published data.

TRR170-DB has a flexible data-driven metadata system that uses tailored metadata blocks for specific data communities. Metadata and files of a published replication dataset can be exported in various open international metadata standards and file formats. This ensures that all published data are generally accessible for other external databases and repositories (“interoperability”).

A major requirement for the reuse of data is metadata information that reflects up-to-date analytical developments. Currently, we are expanding metadata templates to incorporate additional standardized information on samples and materials, analytical methods and additional experimental data in the area of geochemistry. This ongoing process will involve international scientific communities and initiatives (OneGeochemistry, Astromaterials Data System, NFDI, etc.) by discussing and testing joint standards and practice. Our efforts on advancing metadata for geochemical analysis data parallel with establishing an interest group on ’metadata standards for instrumental analysis data in geochemistry’ in the context of the German NFDI4Earth, a consortium of the NFDI Initiative.

title: A new tool to decipher the past silica cycle? The Si isotope signatures of radiolarians: taxa-specific isotope difference and their potential for studying past biogeochemistry
Creators: name: Doering, Kristin
Publisher: name: Deutsche Geologische Gesellschaft - Geologische Vereinigung e.V. (DGGV)

description:
Dissolved silica (DSi) is an essential nutrient for marine silicifiers, and its cycling is closely linked to the biological pump and carbon cycle. The biological uptake of DSi and subsequent formation of biogenic opal (BSi) discriminate against heavier 30Si isotopes, resulting in BSi with lighter isotope compositions than surrounding seawater. The resulting stable isotope compositions (δ30Si) of BSi have proven reliable tools to reconstruct the DSi concentrations of bottom waters (sponges) or surface ocean nutrient utilization (diatoms). However, crucial information from the subsurface and intermediate waters is missing to fully reconstruct silica cycling.

A new tool to close this gap is the δ30Si of radiolarians (δ30Sirad), marine zooplankton dwelling in shallow to deep depths. Radiolarian δ30Si is thought to reflect DSi concentrations of the surrounding seawater, but estimations of a fractionation factor indicating how radiolarians discriminate against the 30Si are difficult due to the inability to culture radiolarians: Accordingly, estimates are limited to analyses to comparisons of radiolarians from surface sediment and DSi concentrations from their habitat depths. So far, only two studies have estimated an apparent fractionation factor (Δ30Si= δ30Sirad - δ30SiDSi) for radiolarians, ranging between -0.0‰ and -1.2‰. The differences in Δ30Si could now be attributed to different radiolarian taxa, likely caused by taxa-specific Si isotope fractionation during DSi uptake.

Significant inverse relationships have also shown the assumed relationship between δ30Sirad and DSi concentrations. However, these relationships still have large uncertainties, and δ30Sirad cannot identify changes below 10 to 15 µM DSi, highlighting the need for more investigations.

description: We study the formation of the directed flow of hadrons in nuclear collisions at energies between AGS and SPS in Monte Carlo cascade model. The slope of the proton flow at midrapidity tends to zero (softening) with increasing impact parameter of the collision. For very peripheral topologies this slope becomes negative (antiflow). The effect is caused by rescattering of hadrons in remnants of the colliding nuclei. Since the softening of the proton flow can be misinterpreted as indication of the presence of quark-gluon plasma, we propose several measurements at NICA facility which can help one to distinguish between the cases with and without the plasma formation.

description: The discussion and definition of the MBS (Multi Body Simulation) parameters and the methods and the types of the MBS softwares along with their special features and advantages has been stated in the start of this thesis so as to get cleared on what is going to be done in MBS title. Different related previously published and reference written articles of literatures regarding the idea of fluid dynamic simulation have then been described to focus on the expected results of this thesis. Also, the limitation and the focusing area have been fortunately guided by these literatures. The load shift and roll performance characteristics of the vehicle with the optimal cross-sections are compared with those of the currently used various other types of tank cross-sections (for various liquid fill conditions); here, the manufacturing cost comparison of local against the imported tankers also duly analyzed referring the cost-break down approach in local factories. The results have been compared and the conclusions with advantages are discussed to decide in selection of the optimal tank cross sectional geometry for shape modeling. The modeling of the tank structure along with the simplified bogie supporting the fluid wagons is done by using the Solidworks 2014 software to show the shape and the relative part mates" contacts to perform the allowable relative motion analysis with respect to the mate. The behavior of the fluid wagon containing the viscous fluids of preferably petroleum base natural oil during the vehicle running has been simulated using both Simpack and ANSYS fluent CFD workbench packages after performing the modeling and the meshing analysis. The graphic result reports from Analytic and each of the MBS softwares have been compiled and discussed so as to observe in comparing the load, the stress and the motion results to decide the critical motion parameters.

description: We present recent optical photometric observations of the blazar OJ 287 taken during September 2015 -- May 2016. Our intense observations of the blazar started in November 2015 and continued until May 2016 and included detection of the large optical outburst in December 2016 that was predicted using the binary black hole model for OJ 287. For our observing campaign, we used a total of 9 ground based optical telescopes of which one is in Japan, one is in India, three are in Bulgaria, one is in Serbia, one is in Georgia, and two are in the USA. These observations were carried out in 102 nights with a total of ~ 1000 image frames in BVRI bands, though the majority were in the R band. We detected a second comparably strong flare in March 2016. In addition, we investigated multi-band flux variations, colour variations, and spectral changes in the blazar on diverse timescales as they are useful in understanding the emission mechanisms. We briefly discuss the possible physical mechanisms most likely responsible for the observed flux, colour and spectral variability.

description: Tannery sludge and the effluents in general are of large-scale environmental concern because they color and diminish the quality of soil and water bodies into which they are released. Their disposal into the environment creates adverse effects by altering the normal physiochemical properties of soil and water. This thesis is aimed to investigate potential application of tannery sludge waste residue for soil conditioning through vermicomposting process by Eisenia fetida and to address the environmental pollution problems in the leather-manufacturing. The performance of the compost was evaluated by biomass of salad grown on vermicompost. The experiments were conducted in circular plastic containers after earthworm-collection and culturing. The containers were filled with different combinations of tannery sludge in combination with cow dung and horse manure in different ratio. In the experimental period (45 days), different parameters were analyzed within a time interval of 15 days like pH, temperature and moisture during vermicomposting processes. While, electrical conductivity, the Total Nitrogen (%), Available Phosphorus (%) and Total Potassium (%) increased at the end of the process, while the % Organic Carbon decreased as the vermicomposting processes progressed. the research has demonstrated that vermicomposting serves different advantages and applications but the two main purposes for the welfare of humans as it helps in the degradation of tannery sludge waste and the vermicompost produced during this process is used as a natural fertilizer. The application and potential utilization of tannery sludge waste for soil conditioning effect has also shown in the increase a biomass of salad.

description:
Heavy halogens are exceptional tracers of fluid provenance due to their largely conservative behaviour during most fluid-rock interaction processes. In particular, Br/Cl ratios have long since been established as a tracer of fluid origin in certain geological settings (e.g. unconformity-related ore systems), where they have significantly contributed to our understanding of ore forming processes. However, mounting evidence suggests that similar Br/Cl signatures can, in fact, be produced by very different geological processes, significantly impacting the applicability of Br/Cl as a fluid source tracer to other crustal environments. Iodine provides an additional proxy and constraint that makes it possible to discern between these different processes and is thus crucial in utilizing the full potential of halogens as fluid provenance tracers. The generally low concentrations of iodine in crustal fluids have posed significant analytical challenges, and iodine analysis was until very recently only possible using bulk analytical techniques.

Recent advances in halogen fluid inclusion microanalysis have made it possible to determine Cl-Br-I systematics in individual fluid inclusions, providing novel opportunities for the study of complex ore forming systems with protracted and complex overprinting fluid signatures. We present a comprehensive triple-halogen fluid inclusion LA-ICP-MS dataset of various magmatic and metamorphic systems, showcasing the power of Cl-Br-I systematics in identifying and characterizing fluid sources, reconstructing processes such as fluid mixing, and the – rather surprising – temporal changes in metamorphic halogen signatures between the Archean and the Phanerozoic.

description:
Precipitation patterns in present-day southeastern Brazil are mainly regulated by the South American Summer Monsoon. The southeast Brazilian Doce Basin is expected to suffer from droughts and flooding as a result of future climate induced shifts in the monsoonal precipitation pattern. Data on past spatiotemporal precipitation shifts are scarce but valuable, especially for climate sensitive regions. We analysed X-ray diffraction-derived mineralogical data for the 150–70 ka period (marine isotope stage (MIS) 6 to MIS 5) on samples obtained from marine sediment core M125-55-7 close to the Doce river mouth (20°S). Within the river-derived fraction, we discriminated between two mineral assemblages with varying abundances between glacial and interglacial times and precession-forced variability only visible in MIS 5. The first assemblage has high contents of kaolinite and gibbsite and indicates intensified lowland erosion of mature tropical soils. The second one has higher contents of well-ordered illite, quartz and albite and points to intensified erosion of immature soils in the upper Doce Basin. Prevailing high kaolinite contents in late MIS 6 indicate pronounced lowland soil erosion and weak monsoonal activity. The dominance of the illite-rich mineral assemblage in MIS 5, particularly during times of high austral summer insolation, indicates strong monsoonal rainfall and physical erosion in the upper catchment. In times of lower insolation in MIS 5, the summer monsoon weakened, leading to decreased precipitation and runoff in the upper catchment and dominant lowland erosion as indicated by an increase in the abundance of the kaolinite-rich mineral assemblage.

description:
The Eoalpine high pressure (HP) belt is part of the Austroalpine basement and reached eclogite facies conditions at 100 to 90 Ma during the Cretaceous Alpine orogenic cycle. It extends over 350 km from the Texel Complex in the west over the Saualpe and Koralpe units to the Pohorje Mountains in the east. While HP to ultra HP conditions are well established, there is still debate on the tectonic history of these rocks. Early studies suggest a continuous subduction along the suture of the Meliata ocean. Other studies suggest a younger intra-continental subduction zone, which formed along a pre-existing weakness caused by Permian rifting. Also, the exhumation mechanisms of these rocks remain unclear. Exhumation through an extrusion wedge has been suggested for the rocks of the Saualpe. The contact toward the hanging wall is interpreted as a low-angle normal fault active during extrusion of the HP rocks. Based on crystallographic preferred orientation (CPO) data, exhumation in an extensional regime along a low angle detachment fault was proposed for the Koraple. Slab extraction has been proposed for both the Koralpe and the Pohorje units, based on pseudosection modeling, which suggests a common exhumation path for the HP units with their hanging wall starting at 1.0 GPa. We will present new CPO data of both metabasalts and the surrounding gneiss matrix from the Koralpe as well as the Pohorje mountains, which will shed some light on the deformation mechanisms active during exhumation and on the overall tectonic history of these rocks.

description:
The oxygen (δ18O) and clumped (∆47) isotope composition of carbonates are widely used proxies for palaeotemperature. However, Earth surface carbonates are rarely formed in isotope equilibrium but often show oxygen and clumped isotope compositions that do not accurately reflect their crystallisation temperature. Isotopic disequilibrium commonly observed in biogenic carbonates and speleothems is inherited from the dissolved inorganic carbon pool of their parent solutions. A combination of isotope systems, e.g., ∆47–δ18O, ∆47–∆48, can uncover and correct for such kinetic effects [1].

The analysis of the 17O/16O ratio to the more commonly investigated 18O/16O ratio in carbonates — referred to as the triple oxygen isotope method — expands the traditional oxygen isotope scheme by another dimension and; thereby, allows the identification of fractionation processes involved in carbonate formation. In addition, the triple oxygen isotope method can give insight into the diagenetic history of ancient carbonates and offers the possibility of reconstructing the primary isotope compositions of altered samples [2].

Here, we report triple oxygen isotope ratios (Δ17O) of various altered and unaltered biogenic (e.g., brachiopods, belemnites) and abiogenic (e.g., speleothems, laboratory precipitates) carbonates. The high-precision measurements were performed on CO2 gas from acid digestion, using tunable infrared laser differential absorption spectrometry (TILDAS) [3]. Based on the results, we will discuss what combination of kinetic isotope fractionation and diagenetic processes could have played a part in the formation of the investigated carbonates.

description:
Reconstructing the earliest evolution of the silicate Earth remains a major geological challenge because of the scarcity and incomplete preservation of rocks older than 3.8 Ga. Isotope variations produced by short-lived radionuclides, such as 146Sm, have the potential to trace the early formation of distinct chemical reservoirs within the silicate Earth, and at the same time can also help decipher the petrogenesis of the oldest-preserved cratonic units.

Here, we present coupled 146,147Sm-142,143Nd systematics of layered gneisses from the Acasta Gneiss Complex (AGC) in northwest Canada. In addition, U-Pb dates of zircon extracted from individual layers and whole-rock major and trace element data are used to constrain the emplacement ages of the gneiss protoliths and their petrogenetic history. Mafic and felsic layers yield average µ142Nd values of +2.7 and −7.5 ppm (±2.5 ppm, 2 S.D.), respectively, documenting the existence of both Hadean mantle and crustal components within the sources of the AGC. Within individual layers, zircon U-Pb data form bands along concordia suggesting ancient Pb loss, with major clusters at 3.5–3.6 Ga for the felsic layers and 3.65–3.75 Ga for one mafic layer. Using these ages, the felsic layers yield consistently negative ε143Ndi values of about −5, while the mafic layers have near-chondritic ε143Ndi. Variations in ε143Ndi and µ142Nd are tightly correlated, suggesting correct age assignment and intactness of the long-lived 147Sm-143Nd system since zircon crystallization. Thus, the studied samples likely record primary 142,143Nd variations, implying that multiple sources were involved in the formation of the AGC protoliths.

description:
The Ruhr Basin in Germany is one of the most extensively studied 3D rock volumes due to decades of subsurface coal mining. Mine flooding associated with the closure of the coalfields may lead to local stress perturbation but also may enable post-mining geothermal applications. However, important geothermal parameters of the Upper Carboniferous clastics are poorly constrained with respect to flow and thermal properties. To improve the understanding of the subsurface heat flux, a dataset of petrophysical parameters is presented for three drill cores of the Westphalian A and B. The studied core material shows fourth order sequences of coarsening/fining upwards cycles in an overall shallowing upward trend. Up to 17 m thick sandstones are associated with a delta front, mudstones and siltstones with a lower delta plain with up to 4 m thick coal seams with a lower delta plain (wetlands) environment. Low compressional wave velocities of 2886 m/s in sandstones are related to higher porosities of up to 15.6%. Likewise, porosity is a major control of thermal conductivity with up to 5.3 W/(m*K) in sandstones. In less porous samples thermal conductivity depends rather on the mineralogy. The low thermal conductivity (mean 3.0 W/(m*K)) of mud and silt-dominated deposits is due to the presence of organic matter or sheet silicates. Generally, low porosity (mean 5.6%) and permeability (mean 0.1 mD) of the rock matrix indicate that fluid flow during mine flooding and potential future geothermal applications will primarily rely galleries and on permeable faults and fracture systems.

description: The presence of knots has been observed in a small fraction of single-domain proteins and related to their thermodynamic and kinetic properties. The exchanging of identical structural elements, typical of domain-swapped proteins, make such dimers suitable candidates to validate the possibility that mutual entanglement between chains may play a similar role for protein complexes. We suggest that such entanglement is captured by the linking number. This represents, for two closed curves, the number of times that each curve winds around the other. We show that closing the curves is not necessary, as a novel parameter $G'$, termed Gaussian entanglement, is strongly correlated with the linking number. Based on $110$ non redundant domain-swapped dimers, our analysis evidences a high fraction of chains with a significant intertwining, that is with $|G'| > 1$. We report that Nature promotes configurations with negative mutual entanglement and surprisingly, it seems to suppress intertwining in long protein dimers. Supported by numerical simulations of dimer dissociation, our results provide a novel topology-based classification of protein-swapped dimers together with some preliminary evidence of its impact on their physical and biological properties.

Year: 2008

description: In recent world the best way of protecting community health mainly depends on preventive methods rather than curative means. Due to this reason, having good solid health-care waste management and disposal in every health-care center is inevitable. The present study is conducted in five systematically selected sample hospitals in Addis Ababa. The main objective of the study was to assess the impacts arose from the current health-care solid waste management, predict proper treatment and disposal mechanism and check the possibility of heat recovery during treatment of waste. The sampling method used is two-stage cluster sampling with 90 % confidence level. In these sample hospitals, solid waste was collected for one week from 84 randomly selected beds of the total occupied 505 beds. The mean waste generation rate for the city was estimated to be 1.227± 0.253 Kg/ day. bed, like wise the generation rate for the private and governmental hospitals were estimated applying the same data. To achieve these results different statistical estimation methods are used. On top of this, proper on site sorting was done in order to perform proximate analysis to seven waste categories. Based on this analysis the maximum infected hospital waste in the city was estimated to be 662 Kg/day. Additionally, an attempt is done to address the overall solid waste management trend all over the routes to disposal. Possible Environmental, health and social impacts are identified for every waste management route. Analyzing the data found, health, environmental and social impact has 37.7, 35.6, and 26.7% impact contribution respectively. To identify the energy recovery of the treatment plant, secondary data from WHO that gives the minimum calorific value for infectious waste and estimated total generation rate of infectious waste in the city was used to determine the energy generation to be 104 Kg/hr, which is less than the capacity of medium sized steam generator. Since the capacity of the energy is less, possible ways of utilizing this small energy was suggested. Finally, based on the results and findings of the present study, certain solid waste management, treatment and disposal recommendations are forwarded to improve the management and minimize the impact of solid health-care waste in Addis Ababa.

description:
Whether Archean tectonics were horizontally or vertically dominated is debated because arguments bear on the kinematics and thermal state of the Archean mantle and constrain the formation of the earliest continental crust. Deformed strata of greenstone belts figure prominently in this debate because they record long periods and multiple deformation phases. Among the best-preserved belts counts the Barberton Greenstone Belt (BGB) of southern Africa. Geological mapping of its southern part in Eswatini (Swaziland), combined with U-Pb zircon dating, show that the region preserves a tightly re-folded imbricate thrust stack in which metavolcanic and -volcaniclastic strata of the Onverwacht Group, deposited at 3.34-3.29 Ga, have been thrust on top of ca. 3.22 Ga siliciclastic strata of the Moodies Group. The structurally highest element, the Malolotsha Syncline, forms a tectonic klippe of substantial size and is >1450 m thick. Forward modelling of a balanced cross section indicates that this thrust stack was part of a northwestward-verging orogen along the southern margin of the BGB and records a minimum horizontal displacement of 33 km perpendicular to its present-day faulted, ductily strained and multiply metamorphosed margin. Because conglomerate clasts indicate a significantly higher degree of prolate strain which extends further into the BGB than at its northern margin, the late-stage tectonic architecture of the BGB may be highly asymmetrical. Our study documents that the BGB, and perhaps other Archean greenstone belts, preserves a complex array of both vertically- and horizontally-dominated deformation styles that interfered with each other at small regional and short temporal scales.

description: The "torus" obscurer of Active Galactic Nuclei (AGN) is poorly understood in terms of its density, substructure and physical mechanisms. Large X-ray surveys provide model boundary constraints, for both Compton-thin and Compton-thick levels of obscuration, as obscured fractions are mean covering factors $f_{\text{cov}}$. However, a major remaining uncertainty is host galaxy obscuration. In Paper I we discovered a relation of $N_H \propto M_{\star}^{1/3}$ for the obscuration of galaxy-scale gas. Here we apply this observational relation to the AGN population, and find that galaxy-scale gas is responsible for a luminosity-independent fraction of Compton-thin AGN, but does not produce Compton-thick columns. With the host galaxy obscuration understood, we present a model of the remaining, nuclear obscurer which is consistent with a range of observations. Our radiation-lifted torus model consists of a Compton-thick component ($f_{\text{cov}}\sim35\%$) and a Compton-thin component ($f_{\text{cov}}\sim40\%$), which depends on both black hole mass and luminosity. This provides a useful summary of observational constraints for torus modellers who attempt to reproduce this behaviour. It can also be employed as a sub-grid recipe in cosmological simulations which do not resolve the torus. We also investigate host-galaxy X-ray obscuration inside cosmological, hydro-dynamic simulations (EAGLE, Illustris). The obscuration from ray-traced galaxy gas can agree with observations, but is highly sensitive to the chosen feedback assumptions.

description: We investigate the influence of dissipation and decoherence on quantum Darwinism by generalizing Zurek's original qubit model of decoherence and the establishment of pointer states (Zurek, Nature Physics 5, 181 - 188 (2009)). Our model allows for repeated multiple qubit-qubit couplings between system and environment which are described by randomly applied two-qubit quantum operations inducing entanglement, dissipation and dephasing. The resulting stationary qubit states of system and environment are investigated. They exhibit the intricate influence of entanglement generation, dissipation and dephasing on this characteristic quantum phenomenon.

description:
The processes that facilitate the production of granitoids are elucidated by the study of exposed lower crustal sections. The focus of this study is an exposure of the lower crustal portion of Albany-Fraser-Orogen (AFO) of Western Australia. This outcrop, located at Whale Head Rock in the western AFO, preserves the interface between an intrusive body and migmatised sedimentary rocks. Detailed mapping, petrography and thermodynamic modelling are combined to characterize the sources and distribution of melt generations in the aureole. U-Pb dating of zircon indicates that the tonalite crystallisation and migmatization of the metapelitic units were coeval at ca. 1.3 Ga. While thermodynamic modelling yields conditions of ca. 820°C and 0.5 GPa, in metapelites throughout the area. The contact zone evolves from igneous dominated textures to migmatitic sediments, dominated by concordant, internally derived leucosomes. The distribution of mineral assemblages and mineral chemistry across this section indicates that the mixing between intrusive and internally generated melt is structurally constrained. The back reaction with late stage, more evolved, melts within this mixing zone indicates that it acts as a pathway for continued melt removal and transport. This study represents and outcrop scale model for the complex processes that are involved in the production of granitoids at high temperature, medium pressure conditions. Giving further insight into the generation and extrapolation of melt from thinned crustal settings.

description: The Moscow State University Extensive Air Shower (EAS-MSU) array studied high-energy cosmic rays with primary energies ~(1-500) PeV in the Northern hemisphere. The EAS-MSU data are being revisited following recently found indications to an excess of muonless showers, which may be interpreted as the first observation of cosmic gamma rays at ~100 PeV. In this paper, we present a complete Monte-Carlo model of the surface detector which results in a good agreement between data and simulations. The model allows us to study the performance of the detector and will be used to obtain physical results in further studies.

Development of Composite Materials for Rail Vehicle Body by Using FEM
Creators: name: Hirpassa, Workineh
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: This thesis work presents the development of composite materials for rail vehicle body by using FEM by considering steel material and bamboo fiber reinforced epoxy composite materials. The Rail vehicle body of tram car model was used to develop the geometric model by Solid work R2017 modeling software. This 3D geometric model was imported to using ANSYS Workbench 15.0. The maximum operational load FEA was done after assigning displacement, load and boundary conditions. The equivalent stress and the displacement are noted and investigated to compare with the literatures revised. The result of this analysis shows that, the equivalent stress of bamboo fiber reinforced epoxy composite Rail vehicle body has the smaller value, as compared with the steel material. Based on these realities, it is recommended that bamboo fiber reinforced with epoxy composite materials are suitable for Rail vehicle body structural analysis.
Probing the dynamical and X-ray mass proxies of the cluster of galaxies Abell S1101

description: Context: The galaxy cluster Abell S1101 (S1101 hereafter) deviates significantly from the X-ray luminosity versus velocity dispersion relation (L-sigma) of galaxy clusters in our previous study. Given reliable X-ray luminosity measurement combining XMM-Newton and ROSAT, this could most likely be caused by the bias in the velocity dispersion due to interlopers and low member statistic in the previous sample of member galaxies, which was solely based on 20 galaxy redshifts drawn from the literature. Aims: We intend to increase the galaxy member statistic to perform a precision measurement of the velocity dispersion and dynamical mass of S1101. We aim for a detailed substructure and dynamical state characterization of this cluster, and a comparison of mass estimates derived from (i) the velocity dispersion (M_vir), (ii) the caustic mass computation (M_caustic), and (iii) mass proxies from X-ray observations and the Sunyaev-Zeldovich (SZ) effect. Methods: We carried out new optical spectroscopic observations of the galaxies in this cluster field with VIMOS, obtaining a sample of ~60 member galaxies for S1101. We revised the cluster redshift and velocity dispersion measurements based on this sample and also applied the Dressler-Shectman substructure test. Results: The completeness of cluster members within r200 was significantly improved for this cluster. Tests for dynamical substructure did not show evidence for major disturbances or merging activities in S1101. We find good agreement between the dynamical cluster mass measurements and X-ray mass estimates which confirms the relaxed state of the cluster displayed in the 2D substructure test. The SZ mass proxy is slightly higher than the other estimates. The updated measurement of the velocity dispersion erased the deviation of S1101 in the L-sigma relation.
