Creators: name: Blen, Tadesse
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Tanning is the chemical process that converts animal hides and skin into leather and related products. The transformation of hides into leather is usually done by means of tanning agents and the process generates highly complex and characterized by high contents of organic, inorganic and nitrogenous compounds, chromium, sulfides, suspended solids and dissolved solids. This study deals with removal of chromium from tannery wastewater using modified Moringa oleifera seed pod (MMOSP) adsorbent. The collected MOSP crushed and sieved to a particle size between 125 and 250µm, Moringa oleifera seed pod was modified or treated with HNO 3 to remove metals and increase its surface area and after the acid treatment, the adsorbent was extracted with methanol to remove inorganic and organic matter from the sorbent surface. Finally washed with distilled water, dried at105 o c and characterized by FTIR and XRD. The adsorption efficiency MMOSP was evaluated as the function of adsorbent dosage, pH and contact time. Atomic absorption spectrometry (AAS) technique was used for the measurement of concentration of Cr (III) before and after adsorption. Batch adsorption experiments were conducted using model pollutant of tannery wastewater. The effects of independent variables on initial Cr (III) concentration of 150mg/L were evaluated. A Cr (III) removal efficiency of 99.78 % would be achieved at pH 5.5, 0.65g and 90min using modified Moringa oleifera seedpod. The experimental results have been fitted well by the Langmuir isotherm model with the higher correlation coefficients of R 2 = 0.999. Thus, indicating to the applicability of monolayer coverage of the Cr (III) on the surface of the MMOSP. Adsorption kinetics was determined using pseudo first order and pseudo second order models and it was found that the adsorption process follows pseudo second order model (R 2 =1). Generally, the results indicate that MMOSP may be used as a low cost adsorbent, alternative for treatment of effluents containing Cr (III).

description: Η παρούσα εργασία αποσκοπεί να διερευνήσει τον ρόλο που διαδραματίζει η παροχή ανακουφιστικής φροντίδας στα νεογνά που νοσηλεύονται σε ΜΕΝΝ και βρίσκονται στο τελευταίο στάδιο της ζωής τους, καθώς και η στήριξη που παρέχει η συγκεκριμένη διαδικασία στη διαχείριση των αρνητικών συναισθημάτων στους γονείς των νεογνών, οι οποίοι καλούνται να αντιμετωπίσουν μια πολύ δύσκολη κατάσταση. Η ανακουφιστική φροντίδα συνιστά μια διαδικασία όπου οι επαγγελματίες υγείας καλούνται να μειώσουν τα συμπτώματα των νεογνών από τις ασθένειες, ώστε να ενισχυθεί σημαντικά η ποιότητα της ζωής τους, ακόμα και εάν αυτή είναι σύντομη. Επίσης, οι επαγγελματίες καλούνται να υποστηρίξουν και τις οικογένειες των νεογνών, οι οποίοι σε πολλές περιπτώσεις δεν γνωρίζουν τον τρόπο με τον οποίο χρειάζεται να ανταποκριθούν στις ανάγκες των παιδιών τους. Οι πρακτικές και οι στρατηγικές που εφαρμόζουν οι επαγγελματίες υγείας κρίνονται καταλληλότερες από εκείνες που δύνανται να παράσχουν οι γονείς, ενώ παράλληλα η μείωση ή η εξάλειψη του πόνου των νεογνών, με τη χρήση αναλγητικών και παυσίπονων, προσφέρει τη δυνατότητα στους γονείς να αξιοποιήσουν το μικρό διάστημα ζωής με τα παιδιά τους. Η μέθοδος έρευνας που χρησιμοποιείται στην παρούσα εργασία στηρίζεται στη συστηματική βιβλιογραφική ανασκόπηση σε έρευνες και μελέτες σχετικά με την ανακουφιστική φροντίδα των νεογνών στις ΜΕΝΝ που δημοσιεύτηκαν κατά την περίοδο 2015-2020. Η αναζήτηση των ερευνών πραγματοποιήθηκε στις βάσεις δεδομένων PUBMED, SCOPUS και SCHOLAR με την εισαγωγή λέξεων κλειδιών και εφαρμόζοντας στη συνέχεια κριτήρια εισαγωγής και αποκλεισμού για τα αποτελέσματα της αναζήτησης. Τα αποτελέσματα της έρευνάς μας ανέδειξαν τη σημαντική συμβολή της ανακουφιστικής φροντίδας στα νεογνά, και τη σημασία παροχής αυτής από επαγγελματίες υγείας, οι οποίοι διαθέτουν τις απαραίτητες γνώσεις για να καταστεί αποτελεσματική μια τέτοια διαδικασία. Τέλος, αναδείχθηκε η σημασία της ανακουφιστικής φροντίδας και στη διαχείριση των αρνητικών συναισθημάτων που βιώνουν οι γονείς των νεογνών.

Rohstoffgewinnung geht mit einer mehr oder minder massiven Veränderung der Landschaft und den natürlichen Verhältnissen einher. Die für unseren Alltag notwendige Entnahme von Ressourcen beeinflusst nahezu alle Aspekte des Naturhaushaltes: Wasser, Boden, Flora und Fauna. Aus geowissenschaftlicher und geoökologischer Sicht betrifft das insbesondere die sogenannten Polder im Ruhrgebiet; Areale, die durch den Steinkohleabbau erhebliche Bergsenkungen erfahren haben und heute kontinuierlich entwässert werden müssen.

Im Projekt „MuSE - Multisensor-Geomonitoring zur Optimierung der nachbergbaulichen Wasserhaltung“ sollen für solche Gebiete Konzepte entwickelt werden, nach denen die Wasserhaltung möglicherweise optimiert werden kann. Ziel ist es, Ideen zu entwickeln, das Polderwasser bspw. in Dürreperioden sinnvoll in Land- und Forstwirtschaft zu nutzen oder den Polder bei Starkregenereignissen vielleicht sogar als Pufferspeicher einsetzen zu können, um zu erwartende Schäden zu verhindern.

Um ein Prozessverständnis aufzubauen, gehen die Geowissenschaftler:innen des FZN dreistufig vor: Neben den klassischen geowissenschaftlichen Ansätzen über die Geologie, den Boden, die Vegetation und Wetterparameter (in situ-Komponente) sollen letztlich Bewertungen auf Basis von Satellitendaten (Sentinel 1 und 2) eine flächenhafte Aussage erlauben. Zur besseren Interpretation dieser Daten werden hochauflösende Multispektraldrohnen eingesetzt, um mögliche Wasser- und Vegetationsindizes abbilden und mit dem Satellitensegment vergleichen zu können. Beispielhaft stellt der Vortrag die kombinierten Ansätze einer Sensordatenfusion aus In situ-Messkomponenten, einer Ground Trouthing-Ebene aus UAV-gestützten Sensoren und (bislang noch eingeschränkt) dem Satellitensegment mit einer Konzentration auf die ersten Beiden Aspekte vor.

description: High speeds have been measured at seep and mud-volcano sites expelling methane-rich fluids from the seabed. Thermal or solute-driven convection alone cannot explain such high velocities in low-permeability sediments. Here, we demonstrate that in addition to buoyancy, osmotic effects generated by the adsorption of methane onto the sediments can create large overpressures, capable of recirculating seawater from the seafloor to depth in the sediment layer, then expelling it upwards at rates of up to a few hundreds of metres per year. In the presence of global warming, such deep recirculation of seawater can accelerate the melting of methane hydrates at depth from timescales of millennia to just decades, and can drastically increase the rate of release of methane into the hydrosphere and perhaps the atmosphere.

Year: 2018

description: This research evaluated the performance of customs clearing agents in Ethiopia by focusing air cargo customs clearing agents to determine their impact on the overall customs clearing processes. The major problem observed in customs clearing process is delay. Explanatory and quantitative methods of research were used. Primary data were collected by questionnaires. Secondary data from ERCA data base also used to determine the transaction performed by the clearing agents and Import/Export status. Data analysis was conducted using descriptive statistics, correlation and regression analysis. The findings of the study suggested that customs clearing agents had significant impact on the customs clearing process. As the SPSS output shows Customs clearing operation, customer service, Information accuracy and relationship with stakeholders had positive significant impact on the performance of the customs clearing agents. Information accuracy had more impact than the others variables. From the survey conducted and filled by customers, it was found also that the delay on customs clearing process is confirmed. The study concluded the improvement on the above four will improve the customs clearing process and this will lead to minimize the delay. The research recommended the customs clearing process should supported by ICT and stakeholders specially ERCA should support and give due attention for customs clearing agents

description:
Diffusion studies in minerals are a fundamental tool for understanding the rheological properties of Earth’s mantle. Previous theoretical studies on deformational strain rates show that the key mechanism for deformation in bridgmanite (Brg) is diffusion-controlled creep of the slowest element, Si. The Al, Si interdiffusion rate in Brg is thus essential for understanding mantle dynamics. Brg diffusion couples were synthesised from 0-5 mol.% Al2O3-bearing MgSiO3 enstatite at 24 GPa and 2023 K using a conventional multianvil apparatus. A scanning transmission electron microscope (STEM) can provide a resolution down to the nanometre scale and is therefore ideal for studying slow diffusion, such as in this study. To achieve reliable results from STEM analysis, it is necessary to carry out sample preparation carefully. In this study, a focused ion beam was used for (S)TEM sample preparation. The Al substitution mechanisms in Al-bearing Brg diffusion couples in the recovered samples were analysed using an energy-dispersive X-ray spectrometer. The measured diffusion coefficient for Al, Si interdiffusion at 24 GPa and 2073K was Log10(D) = -20.1 ± 0.7 (based on units of m2/s). The result is two to three orders of magnitude slower compared to the previously reported Si self-diffusion coefficient Log10(DSi) = -18 ± 0.5 at 25 GPa and 2073 K. The slower diffusion rate places limits on deformational strain rates of Brg in the lower mantle.

description: We will show that the period $T$ of a closed orbit of the planar circular restricted three-body problem (viewed on rotating coordinates) depends on the region it encloses. Roughly speaking, we show that, $2 T=kπ+\int_Ωg$ where $k$ is an integer, $Ω$ is the region enclosed by the periodic orbit and $g:\mathbb{R}^2\to \mathbb{R}$ is a function that only depends on the constant $C$ known as the Jacobian integral; it does not depend on $Ω$. This theorem has a Keplerian flavor in the sense that it relates the period with the space "swept" by the orbit. As an application, we prove that there is a neighborhood around $L_4$ such that every periodic solution contained in this neighborhood must move clockwise. The same result holds true for $L_5$.

Year: 2016

description: There are many reasons for affecting of the freight train disc properties. The braking system failures takes lion's share of to affect the brake disc in operation. Under normal condition the disc should have enough thermal capacity so that they can handle the heat developed by friction during normal braking action. However, in any braking components failures the braking force will be uncontrolled. Therefore, this thesis deals with the effects of uncontrolled braking force on thermomechanical propertied of discs. Particularly this paper emphasis on the effect of uncontrolled brake force on brake disc which is created due to overcharging and losses of air in braking components. The purpose of the study is to show, how the brake disk is affected its performance (thermomechanical properties) due to uncontrolled brake force. At the end, this thesis helps to give a true picture to Ethiopian Railway Corporation (ERC) about pri maintenance on the braking components before any operation. Since any failures of braking system has effects on braking action and it has a consequences on disc performance. In the analysis a three dimension finite element model of the brake disc is used to investigate the effects of uncontrolled braking force due to service braking. The specimens are modeled by CATIA V5 R19 and analysis is done by ANSYS 12 and by imposing the uncontrolled forces. The findings of this analysis will observed from ANSIS solution and give conclusion based on the design standards and finally ended with recommendation.

description:
Suitable raw material is the basis for every ceramic object. In order to study the artisanal choices and factors associated with the selection of clays for Bronze Age ceramic production a raw-material survey has been carried out near the excavation site of Grutt’i Acqua on the peninsula of Sant'Antioco (Sardinia). This project is characterized by a transdisciplinary combination of experimental archaeology and mineralogical material science analysis - carried out in a cooperation between ArchaeoLytics and the Institute for Archaeological Studies of the Ruhr-University Bochum.

Nineteen clay-rich sediments have been collected and processed to examine their suitability to produce pottery according to local Bronze Age techniques and diagnostic vessel shapes. Based on standardized test-tiles the dry- and fire-shrinkage as well as the color-variations have been recorded for firing-experiments at 600 and 900°C. Ten samples out of this series have been selected for further investigations including polarizing microscopy, XRD and XRF. Preliminary comparisons with local Bronze Age shards show clear distinguishing features, allowing a solid provenance study. In addition, our field experiences, the in-situ processing of raw materials and the X-Ray data provide us with a more profound and broader understanding of the local Bronze Age pottery in the area of Grutt’i Acqua.

description:
The isotopic and chemical properties of organic matter (OM) in extraterrestrial samples record a combination of presolar, nebular, parent-body, and terrestrial processes, which can be disentangled by high-spatial resolution studies [e.g., 1]. These studies have the advantage that they also allow for analysis of the petrographic relationship to the matrix and require only minimal chemical treatment. Here we have investigated OM properties within two recent observed falls, Tarda and Winchcombe, by combined “in-situ” techniques. Carbon and nitrogen isotopic compositions were studied by NanoSIMS. OM was sectioned by the focused ion beam (FIB) technique (Hitachi Ethos NX5000). Scanning Transmission X-Ray Microscopy (STXM) was performed at the I08 beamline of Diamond Light Source. Low-kV electron energy loss spectroscopy (EELS) in the vibrational and core loss regimes was performed with a monochromated, aberration-corrected Nion UltraSTEM 100MC. Nitrogen and carbon isotopic compositions of OM aggregates and nanoglobules in Tarda show a range of δ15N values from close-to-terrestrial to ~600‰ with close-to-terrestrial or slightly heavy δ13C values. Single hotspots reach >1000‰ in δ15N and ~80‰ in δ13C, but no negative δ15N values similar to Maribo OM have been detected [2]. STXM analyses at the C K-edge show that OM in Winchcombe is typical for OM in primitive meteorites, with strong absorption at the aromatic C=C (~285 eV) and the ketone/aldehyde (~286.6 eV) bands. The presence of reactive double and triple C-N bonding is a strong indicator that some OM is still pristine.

description:
As the best-preserved fragment of paleo oceanic crust on land, the Samail ophiolite (Sultanate of Oman) allows extensive field studies on fast-spread lower oceanic crust. Drill core GT1 of the Oman Drilling Project in the frame of ICDP (International Continental Scientific Drilling Program) spans about 400 m from the layered gabbros between ~1200 and 800 m above the crust-mantle boundary (maM). The drilled samples are mostly gabbros or olivine gabbros and we applied petrological, geochemical, and microstructural methods to identify those magmatic processes relevant for the lower crust accretion. Mg# (Mg/Mg+Fe x 100; molar basis) in olivine and clinopyroxene and the Ca# (Ca/Ca+Na x 100; molar basis) in plagioclase show parallel fractionation trends from 800 to 1070 maM which can be subdivided into four 25 to 80 m-thick smaller trends. Above 1070 maM, phase compositions change towards more primitive compositions over a 15 m-thin horizon, revealing decameter-scale fractionation over the uppermost 80 m of the core. These trends are confirmed by bulk rock Mg# and Cr/Zr ratios and thermodynamic modeling suggests that they can result from in-situ fractionation by a crystallization degree of less than 30 mol% followed by primitive melt replenishment. Thus, the necessity of removing latent heat which is regarded as critical in terms of in-situ crystallization is only limited, because most melt migrates upwards, without crystallizing. Our results suggest that magma replenishment and fractional crystallization are the key processes responsible for the accretion of the layered gabbro section of the Oman paleocrust.
Addis Ababa City Light Railway Transit Speed Profile for Optimum Train Drive: Case of Line from Menelik Square to Kality
Creators: name: Abebe, Teklu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Optimum train driving is the key aspect of railway transportation development and depends on energy consumed, passenger comfort and punctuality. In this thesis three mathematical models have been developed considering nearly all traction mechanics and track information to generate appropriate speed profile. The first problem solved is minimization of energy consumed whereby the given journey must be completed on the allocated time. The second problem is minimization of journey time to complete the given journey; here the maximum energy consumed (the drive rating not to be exceeded) for fastest train drive is taken as one of the constraints. The third problem is designed to have different speed profile for different traffic condition ranging from high to low exempting the two extremes. In order to generate appropriate speed of the train at each discrete point, we used genetic algorithm with Deb's constraint handling technique. Finally, we implemented the problems for North to South line of Addis Ababa light railway transit. The result obtained from simulation helps the driver to attain the required driving performance by driving the train with the respective speed profile.

description: We present a real-time and fully integrated quantum random number generator (QRNG) by measuring laser phase fluctuations. The QRNG scheme based on laser phase fluctuations is featured for its capability of generating ultra high-speed random numbers. However, the speed bottleneck of a practical QRNG lies on the limited speed of randomness extraction. To close the gap between the fast randomness generation and the slow post-processing, we propose a pipeline extraction algorithm based on Toeplitz matrix hashing and implement it in a high-speed field-programmable gate array. Further, all the QRNG components are integrated into a module, including a compact and actively stabilized interferometer, high-speed data acquisition, and real-time data post-processing and transmission. The final generation rate of the QRNG module with real-time extraction can reach 3.2 Gbps.

Year: 2016

description: Heavy metals are considered a major cause for environmental problems. Several conventional treatment methods have been developed for removal of toxic metal ions from wastewaters. Currently biological materials have received attention for heavy metal removal and recovery due to their good performance, low cost and availability. Among the broad lists of biosorbent materials, brewery spent grain has utilized for this study to remove, lead and chromium from wastewater. BSG was modified with 1M NaOH and afterward it was washed, dried and grinded to have particles sizes of 250-500μm. Lead (II) and Chromium (VI) stock solutions were prepared and from which different concentrations were obtained by serial dilution. Batch adsorption of Lead (II) and Chromium (VI) onto BSG was studied. The results indicated that the maximum percentage removal of lead and chromium was found to be 96.53% and 79.47% at pH= 4 and pH=2 respectively. The adsorption data of metal ions have been described by the Freundlich and Langmuir isotherm models. The sorption process conformed to both Langmuir and Freundlich isotherms with maximum sorption capacities of 26.3 and 10.75 mg/g for lead and chromium, respectively. Sorption kinetics for lead and chromium(VI) followed pseudo second order with regression coefficients of 0.9999 and 0.9998 respectively. Optimum operating conditions of 10 g/l adsorbent dose, 120 minutes and pH=2 for Cr(VI) and pH= 4 for Pb(II) solution were applied to remove lead and chromium ions from real electroplating wastewater. The results showed that brewery spent grain reduced lead ions from its initial concentration of 82 mg/l to 38.37 mg/l while chromium ion was reduced from 156.9 mg/l to 88.73 mg/l. Therefore, it can be concluded that modified spent grain as a new effective adsorbent has potential for Pb(II) and Cr(VI) removal from aqueous solutions.

description:
Environmental uranium (U) contaminations may be remediated by using microbes to reduce mobile hexavalent [U(VI)] to more immobile tetravalent U [U(IV)]1. However, the subsurface stability of U(IV), usually present as solid-phase non-crystalline U, can be affected by reactions with ligands, oxidants or bacteria. Uranium isotopes have the potential to monitor and assess these mobilization/immobilization processes, however, currently detailed knowledge of their fractionation in all involved individual processes is lacking.

Here, we present laboratory experiments, investigating the efficacy of Acidithiobacillus (At.) ferrooxidans to mobilize non-crystalline U(IV) and associated U isotope fractionation. As starting material an U(VI) isotope standard was reduced by Shewanella oneidensis MR-1 in a phosphate-containing medium (WLP) in order to produce non-crystalline U(IV). At. ferrooxidans mobilized between 74% and 91% U after one week, and interestingly, U mobilization was observed for both, living and inactive cells. This finding raises doubts on the long-term sustainability of in-situ bioremediation measures at U-contaminated sites.

In contrast to mobilization with ligands, which results in 238U enrichment in the mobilized phase2, mobilization by At. ferrooxidans did not cause U isotope fractionation, potentially because of a layer effect3. Thus, isotopic signatures found in nature are more likely associated with other processes such as U reduction, abiotic oxidation, or mobilization with ligands.

description: Η παρούσα διπλωματική εργασία έχει ως σκοπό να διερευνήσει πόσο σημαντικό είναι το συναίσθημα στην αποτελεσματική διαχείριση του ανθρώπινου παράγοντα στην εργασία. Ο αντικειμενικός σκοπός της συγκεκριμένης εργασίας δεν είναι μόνο να δοθεί ο ορισμός του συναισθήματος και να αναλύσει τα είδη της συναισθηματικής νοημοσύνης. Έχει ως κύριο στόχο να περιγράψει τα είδη της ανθρώπινης νοημοσύνης, να γίνει κατανοητό ότι δεν υπάρχει άμεση συσχέτιση της ευφυΐας με την ανάπτυξη της συναισθηματικής νοημοσύνης. Ανά δεκαετίες όπως θα δούμε και αναλυτικά στη συνέχεια της εργασίας, έχουν διατυπωθεί διάφορα μοντέλα για τη συναισθηματική νοημοσύνη. Στη συνέχεια, γίνεται αναφορά, στη διοίκηση ανθρώπινου δυναμικού. Το πόσο σημαντικό μέρος είναι για έναν οργανισμό , τι αρμοδιότητες έχει πως οργανώνεται αλλά και πόσο έχει αλλάξει στην Ελλάδα με την πάροδο των ετών. Η προσέλκυση αλλά και η διατήρηση των ανθρώπων που απαρτίζουν έναν οργανισμό είναι κάτι το οποίο δεν είναι εύκολο. Θα αναλυθεί προσεχώς ποια είναι η διαδικασία της προσέλκυσης των εργαζομένων, οι μέθοδοι προσλήψεων και η διατήρηση των ανθρώπων μέσα στην επιχείρηση. Στο τέταρτο κεφάλαιο της παρούσας εργασίας, θα γίνει αναφορά στη συναισθηματική νοημοσύνη και την εργασία. Δηλαδή, το πόσο επηρεάζουν, είτε είναι θετικά, είτε αρνητικά τα συναισθήματα την εργασία μας. Θα γίνει ακόμη και μία μικρή αναφορά σχετικά με την ηγεσία και τη συναισθηματική νοημοσύνη.

description:
Eclogite-facies metamorphic veins provide records of fluid flow dynamics during high-pressure metamorphism. Here, we evaluate the inventory of quartz-rich metamorphic veins and segregations in Variscan eclogites from the Münchberg Massif (NE Bavaria) to investigate the fluid origin and the scale of fluid flow. These eclogites experienced peak P-T conditions around 3 GPa and 700°C, and a continental rather than oceanic mafic igneous protolith setting is proposed.

Isolated, mm-sized quartz pockets with euhedral high-pressure minerals are common in the Münchberg eclogites, but continuous veins that may have allowed focused fluid flow to beyond specimen scale are rare. Nevertheless, where such veins occur, they can contain eclogite assemblages including minerals such as omphacite, garnet, rutile, kyanite, and phengite. Oxygen isotope thermometry of quartz-garnet, quartz-phengite, and quartz-kyanite pairs yield temperatures around 700°C. δ18O values of quartz (+6.1 to +10.5‰) from almost all the veins are identical to predicted (from mass balance modelling at 700°C based on host rock δ18O values from +4.0 to +7.9‰) equilibrium δ18O values of host rock quartz.

The veins and pockets are mostly in equilibrium with their host eclogites regarding texture, mineralogy, mineral chemistry, and oxygen isotopes. They seem to represent former cavities filled by internally-derived fluids, whereas indications for fluid transport beyond specimen scale are rare. The abundance of isolated quartz pockets and scarcity of more extended veins suggest that rather low quantities of fluid were produced. This may be typical for continental eclogites, which are supposed to have experienced little pre-subduction hydration compared to oceanic eclogites.

description:
We investigated three fluorite deposits associated with the Bushveld Igneous Complex in South Africa for their trace element characteristics (e.g., REE+Th+U): the two major and world-class Vergenoeg and Buffalo deposits, as well as the small Morgenzon deposit. Combined with published and unpublished data from the Vergenoeg deposit (host rock and mineral separates), which yield an age of 2050 ± 17 Ma (MSWD = 0.65), the new host rock and fluorite Sm-Nd isotope data confirms a primary magmatic origin for the Buffalo deposit as well. Whereas the host rock data for Morgenzon plot close to the 2050 Ma isochron, the Morgenzon fluorite data significantly diverge and plot along an errorchron corresponding to an age of 318 ± 59 Ma (MSWD = 7.4). The Morgenzon fluorites are also depleted in the abundances of REE+Th+U by almost a factor 100 compared to the Buffalo fluorites. Cathodoluminescence (CL) imaging reveals complex zoning patterns with a wide range in bluish CL colours for the Morgenzon fluorite. In contrast, fluorite from Buffalo is always very homogeneous (pale bluish CL colour), which indicates a single stage and likely primary magmatic formation process for the latter. Combined trace element and isotope data and CL evidence for the Morgenzon deposit suggest a late hydrothermal fluorite formation unrelated to the Bushveld igneous event.

description:
The formation of oceanic crust at mid-ocean ridges is one of the dominant processes in the chemical differentiation of our planet. Oceanic crust formed at fast-spreading ridges exhibits a relatively uniform seismic stratigraphy and is regarded as layered and relatively homogeneous in mineralogy. Because of the lack of natural in-situ exposures at the base of the crust of recent oceans, existing models on the geodynamics of the deep processes during crustal accretion have never been tested directly using natural samples. Using the CM1 and CM2 drill cores penetrating the Oman ophiolite sequence, the best analogue for fast-spreading crust on land, recovered by the ICDP Oman Drilling Project, we started a study combining experimental work and investigations on samples of the drill cores in order to shed light on the nature of this the poorly understood crust-mantle transition. The drill cores CM1 and CM2 cover the upper mantle harzburgites at the bottom, followed by a 90 m thick massive dunite layer with layered gabbros at the top. Ni and Mg# in olivine as well as Cr#, Mg# and trace elements in chrome spinel were analyzed by EPMA and fs-LA-ICP-MS. The data reveals a homogeneous harzburgite composition, followed by homogeneous dunite in the lower part and an upper dunite section showing decreasing Mg#, and therefore more differentiated compositions towards the top. We conclude that only the upper half of the 90 m thick dunite has a cumulative origin. The lower dunite section may be formed as a result of reactions with harzburgite.

Astrobiological Effects of Gamma-Ray Bursts in the Milky Way Galaxy

description: A planet having protective ozone within the collimated beam of a Gamma Ray Burst (GRB) may suffer ozone depletion, potentially causing a mass extinction event to existing life on a planet's surface and oceans. We model the dangers of long GRBs to planets in the Milky Way and utilize a static statistical model of the Galaxy that matches major observable properties, such as the inside-out star formation history, metallicity evolution, and 3-dimensional stellar number density distribution. The GRB formation rate is a function of both the star formation history and metallicity; however, the extent to which chemical evolution reduces the GRB rate over time in the Milky Way is still an open question. Therefore, we compare the damaging effects of GRBs to biospheres in the Milky Way using two models. One model generates GRBs as a function of the inside-out star formation history. The other model follows the star formation history, but generates GRB progenitors as a function of metallicity, thereby favoring metal-poor host regions of the Galaxy over time. If the GRB rate only follows the star formation history, the majority of the GRBs occur in the inner Galaxy. However, if GRB progenitors are constrained to low metallicity environments, then GRBs only form in the metal-poor outskirts at recent epochs. Interestingly, over the past 1 Gyr, the surface density of stars (and their corresponding planets) that survive a GRB is still greatest in the inner galaxy in both models. The present day danger of long GRBs to life at the solar radius ($R_\odot=8$ kpc) is low. We find that at least $\sim$65% of stars survive a GRB over the past 1 Gyr. Furthermore, when the GRB rate was expected to have been enhanced at higher redshifts, such as $z\gtrsim0.5$, our results suggest that a large fraction of planets would have survived these lethal GRB events.

The Effects of Vitamin D Supplementation on Respiratory Infections in Children Under 6 Years Old: A Systematic Review
Creators: name: Bratosin, Felix
Publisher: name: Open Science Framework
Year: 2023
Subjects: subject: Medicine and Health Sciences

description: The primary hypothesis of this systematic review is that adequate vitamin D levels are associated with a reduced risk and severity of childhood respiratory infections. Consequently, the main objective of this systematic review was to assess the effectiveness of vitamin D supplementation in decreasing the incidence and severity of RTI in the pediatric population of children between 0 and 5 years old, while the secondary objective was to explore potential effect modifiers, such as age, baseline vitamin D status, and type of respiratory infection. By synthesizing the available evidence, this systematic review aims to provide a comprehensive and up-to-date understanding of the role of vitamin D in child-hood respiratory infections, which may ultimately contribute to the development of targeted interventions and strategies to reduce the burden of these common and impactful illnesses.

description: Introduction: Guideline recommendations are meant to help minimize morbidity and to improve the care of nonmuscle invasive bladder cancer (NMIBC) patients but studies have suggested an underuse of guideline-recommended care. The aim of this study was to evaluate the level of adherence of German and Austrian urologists to German guideline recommendations. Methods: A survey of 27 items evaluating diagnostic and therapeutic recommendations (15 cases of strong consensus and 6 cases of consensus) for NMIBC was administered among 14 urologic training courses. Survey construction and realization followed the checklist for reporting results of internet e-surveys and was approved by an internal review board. Results: Between January 2018 and June 2019, a total of 307 urologists responded to the questionnaire, with a mean response rate of 71%. The data showed a weak role of urine cytology (54%) for initial diagnostics although it is strongly recommended by the guideline. The most frequently used supporting diagnostic tool during transurethral resection of the bladder was hexaminolevulinate (95%). Contrary to the guideline recommendation, 38% of the participants performed a second resection in the case of pTa low-grade NMIBC. Correct monitoring of Bacille Calmette-Guerin (BCG) response with cystoscopy and cytology was performed by only 34% of the urologists. Conclusions: We found a discrepancy between certain guideline recommendations and daily routine practice concerning the use of urine cytology for initial diagnostics, instillation therapy with a low monitoring rate of BCG response, and follow-up care with unnecessary second resection after pTa low-grade NMIBC in particular. Our survey showed a moderate overall adherence rate of 73%. These results demonstrate the need for sharpening awareness of German guideline recommendations by promoting more intense education of urologists to optimize NMIBC care thus decreasing morbidity and mortality rates.

description: We develop and apply several strategies for setting physical parameters on quantum annealers for application problems that do not fit natively on the hardware graph. The strategies are tested with a culled random set of mixed satisfiability problems, yielding results that generalize to guidelines regarding which parameter setting strategies to use for different classes of problems, and how to choose other necessary hardware quantities as well. Alternate methods of changing the hardware implementation of an application problem are also considered and their utility discussed.
