description:
Silicate weathering sequesters CO2 from the atmosphere and stabilizes Earth’s climate over geologic timescales. In turn, weathering of accessory carbonate and sulfide minerals is a geologically relevant CO2 source. Rock-uplift and -erosion is the primary mechanism by which fresh minerals are exposed to weathering at Earth’s surface. Therefore, the global inorganic carbon cycle is sensitive to mountain uplift and erosion. However, quantifying this sensitivity is complex, because existing data do not consider weathering of all relevant mineral phases, and because co-variation of multiple environmental factors obscures the role of erosion. Here, we analyze the sensitivity of silicate, carbonate, and sulfide weathering fluxes to erosion in solute chemistry from four small mountain streams that span well-defined erosion-rate gradients in relatively uniform metasedimentary lithologies. Across all datasets and 2-3 orders of magnitude of erosion rate, we find that silicate weathering fluxes are almost insensitive to erosion at rates >10-2 mm yr-1. In contrast, weathering fluxes from sulfide and carbonate minerals increase sub-linearly with erosion. By fitting a weathering model to these data, we show that the contrasting sensitivities of silicate, carbonate, and sulfide weathering produce a distinct CO2-drawdown maximum at moderate erosion rates of ~0.1 mm/y. Below this maximum, mineral supply limits silicate weathering. Above the maximum, silicate weathering fluxes plateau and CO2 emissions from coupled sulfide oxidation and carbonate weathering increasingly dominate the carbon budget. Overall, uplift of metasedimentary lithologies to moderate relief can substantially bolster Earth’s CO2 sink whereas further uplift may decrease, or even reverse, CO2 sequestration rates.

description:
Alluvial river adjustment occurs in response to altered sediment and water inputs, driven by both natural and anthropogenic climate change, changes in land use and/or land cover, and/or imposed by tectonic boundary conditions. This river response is ultimately reflected in the geometry of the bankfull channel, the planform characteristics of the river, and the longitudinal profiles of the mainstem river and its tributaries. This study utilizes analyses of river longitudinal profiles and provides a powerful tool to detect the change and extend it to long-term landscape evolution. Wickert and Schildgen (2019) developed the model, GRLP, to compute transient and steady-state solutions for the long-profile evolution of transport-limited gravel-bed rivers with self-forming channel-width adjustments. Following an analogous approach to that taken by Wickert and Schildgen (2019) and linking sediment transport and river morphodynamics, we developed a model describing the long-profile evolution of a transport-limited sand-bed river. This sand-bed model allows for planform adjustments as a function of excess shear stress (following Parker, 1978, and Dunne et al., 2018) thereby linearizing the sediment-transport response to changing river discharge. Ultimately, the resultant equations suggest a diffusive form for sand-bed river long-profile form and evolution. Both models were further built to work with the Landlab component library. Here, with these Landlab compatible models, we further present examples of sand- and gravel-bed river long-profiles under a variety of water- and sediment-supply boundary conditions, and present the transition into models of linked tributaries reproducing river-network evolution over both human and geological time scales.

Astronomical insolation forcing is now well-established as the underlying metronome of Quaternary ice ages and Cenozoic climate carbon-cycle feedback mechanisms. However, its effects on earlier Eras (Mesozoic, Paleozoic, and pre-Cambrian) are less understood. In this presentation, I will evaluate various pre-Cenozoic modes of response to astronomical forcing, and provide an overview of the Earth System components that were particularly sensitive to astronomical forcing under evolving boundary conditions. Subsequently, the role of astronomical forcing in pacing the global carbon cycle in the Devonian warmhouse and Cretaceous hothouse worlds is discussed. Both periods are characterized by recurrent ocean anoxia and remarkably similar hypotheses exist regarding how astronomical forcing could have amplified a nutrient surplus (from chemical weathering and volcanism, respectively) to tip the ocean system into anoxia. The Triassic-Jurassic boundary cyclostratigraphy illustrates the importance of precession-scale time-control to understand feedback mechanisms and cause-and-effect chains at a resolution that is relevant for making analogies with the present-day. Finally, this presentation provides an outlook on the need for a coordinated approach, using so-called astrochronozones, to establish a fully astronomically-calibrated timescale for the Phanerozoic. Overall, I will highlight the need for a more comprehensive understanding of the role of astronomical insolation forcing in shaping Earth's climate over geologic time.

Earthquakes are a direct response to the Earth’s state of stress, which is one of the key ingredients controlling the lithosphere rheological behavior. To first order, the total in-situ stress is a function of two main co-players: the long-term tectonic stress, and the short-term (seismic cycle) stress transfer. Despite their diversity in temporal and spatial scales, these components are not mutually independent, but they do interact in the final rheological configuration of the lithosphere

Understanding the relative importance of different tectonic loads and how the stress is transferred is of high relevance for robust earthquake simulators. As the stress transferred to a fault affects its mechanical behavior, it has a direct control on its potential to generate earthquakes.

Recent studies suggest that the regional tectonic environment surrounding the faults (e.g., off-fault lithology, lithospheric structure, and degree of coupling between crustal and mantle domains) can influence fault behavior. However, the importance of such heterogeneities in modulating background seismicity needs to be properly evaluated to unveil the behavior of these complex systems.

3D data-integrative and gravity-consistent models are useful tools for characterizing such lithospheric-scale heterogeneities, and ultimately, to analyze their potential relationship with background seismicity. In this contribution, we present the preliminary results of a 3D lithospheric model of the southern San Andreas Fault system, where the wealth of available data was considered. We demonstrate that this is an important step towards the calculation of the background off fault stresses due to local loadings, which likely influence background seismicity.

In addressing climate change as one of the key problems of humanity (IPCC 2014), the school subject of geography is of particular importance, as it is a leading subject for Education for Sustainable Development with a pronounced systemic character (DGfG 2020). In this highly relevant area, on the one hand, the interest of students is considered a decisive prerequisite for the success of learning processes. On the other hand, students’ interest is also regarded as an important goal of (geography) lessons (Krapp 1998) - yet there are hardly any differentiated findings on its characteristics regarding climate change.

Against this background, in a quantitative, questionnaire-based study N = 4627 students in the federal state of Bavaria were surveyed about their topic-specific interest in climate change, and the data were analyzed both descriptively and interference-statistically. Overall, the students show a high level of interest in climate change. However, there are remarkable differences regarding different aspects of climate change, as well as between genders and between students attending different types of schools. Aspects related to actions against climate change as well as to the global level are considered more interesting than aspects concerning spatial proximity and climate change measurement/methodology, and girls show an overall higher interest in climate change than boys do. Furthermore, students attending grammar school (“Gymnasium”) show a higher interest than students attending secondary school (“Realschule”), and these in turn than students attending lower-level secondary school (“Mittelschule”). These and the results of further analyses of the survey will be presented.

description: The wool carder bee Anthidium manicatum is one textbook example of resource defense polygyny among solitary bees, known for intense male–male competition, forced copulations, and the extreme form of interspecific territoriality toward other flower visitors. This mating system depends on the spatial structure of the defended resource and requires several adaptations in males. The allocation of patches with host plants as well as male body size and phenology was analyzed over 3 years in the diverse habitat of a botanical garden. Anthidium manicatum males searched in groups up to 12 individuals a wide diversity of patches with various food plants of foraging females. Territories were established in small high-quality patches only. Males abandoned aggressive and territorial behavior in large patches. Available patches were occupied by males of the various body size fractions independently of each other according to patch profitability. The higher competitive weight of large males in small patches compared to spacious ones was balanced by an opposing correlation of patch profitability. Although the mating system in A. manicatum is clearly a resource defense polygyny, males were found to be plastic in their behavior, and territoriality was not consistently observed. Mate acquiring tactics, be they territory holder (bourgeois), sneaker, floater, or scrambler for mating, can be considered to be different behavioral phenotypes within one environmentally sensitive conditional strategy.

description:
The Ruwai Pb-Zn-Ag skarn deposit is located within the Schwaner Mountain Complex in Central Kalimantan, Indonesia. It is the largest polymetallic skarn deposit in Kalimantan with the resources is estimated up to 14.43 Mt. at 4.94 wt.% Zn, 3.28 wt.% Pb, 108.11 g/t Ag which hosted by Jurassic limestones of the Ketapang Complex and Cretaceous granitoids of Sukadana Complex. In order to study the complex mineralogy and deportment of critical-elements (Ag, Bi, Sb, In, Te, Cd) pulp samples from the main stages of the processing plant (Ball mill/feed, Pb concentrate, Zn concentrate, Pb scavenger, Zn scavenger, Fe screw, and tailings) as well as 66 core samples of Pb-Zn-Ag mineralization were obtained.

Preliminary results on the pulp samples from X-ray diffraction (XRD), X-ray fluorescence (XRF) and mineral liberation analysis (MLA) agree within analytical uncertainties. The data allows a preliminary assessment of the deportment and distribution of Ag and Bi in the skarn ores and processing products. Particularly, acanthite (Ag2S) and freibergite ((Ag,Cu,Fe)12(Sb,As)4S13) are likely to be important hosts of Ag, while Bi occurs within bismuthinite (Bi2S3) and native bismuth (Bi). For the core samples, µ-XRF measurements of slabs have so far provided a broad overview of elemental distribution within the samples, while XRD results indicate more complex mineralogical compositions than the pulp samples.

Further analytical work including electron probe microanalysis (EPMA) and laser ablation ICP-MS are planned for all samples to be also able to evaluate the resource potential of other critical elements of interest such as Sb, In, Te, Cd.

Neuropathic pain and the multiple sclerosis prodrome : a population-based matched cohort study
Creators: name: Bergeron-Vitez, Himali
Publisher: name: University of British Columbia
Year: 2024

description: Introduction: There is evidence of a prodromal phase in multiple sclerosis (MS), which may involve increased health care visits for pain-related issues in the years preceding MS onset. Over 50% of MS patients experience neuropathic pain, with gabapentinoids and/or other anticonvulsants among the first-line treatments for neuropathic pain. This study’s objective was to estimate the number of MS cases vs matched controls who filled at prescriptions gabapentinoids with and without other anticonvulsants (as use of both may suggest epilepsy treatment). Methods: This population-based matched cohort study used health administrative data from British Columbia, from 1996 to 2013. MS cases were defined based on a previously validated criteria and their first demyelinating-disease claim was defined as the index date. Up to 5 controls were matched to cases by sex, age, calendar-year, and geographical location at index date. In the five years before the index date, we compared cases and controls regarding use of anticonvulsants and gabapentinoids not combined with anticonvulsants Age-and-sex adjusted odds ratios (aOR) and 95% confidence intervals (CIs) were estimated using logistic regression. Results: The cohort comprised 4,862 MS cases and 22,669 controls; 72% were female. In the 5 years before the index date, 992 (20%) cases and 1,600 (7.1%) controls filled at least one prescription for any anticonvulsant, while 371 (7.6%) cases and 473 (2.1%) controls filled at least one prescription for gabapentinoids not combined with any other anticonvulsants. The odds of a filled prescription were higher for cases than controls for any anticonvulsants (aOR = 3.40, 95% CI: 3.12, 3.71), and for gabapentinoids without other anticonvulsants (aOR = 4.05, 95% CI: 3.52, 4.66). Conclusion: Neuropathic pain-related medication use was more common for MS patients in the five years before MS onset versus matched controls, suggesting that neuropathic pain may be part of the MS prodrome.

description:
High-temperature aquifer thermal energy storage (HT-ATES) in the geological subsurface can help bridge the temporal mismatch between production and demand of energy from renewable sources. Despite great importance for energy system transformation in the heat supply sector, HT-ATES faces some challenges and risks such as regulatory challenges. The heat input experiments at the TestUM –Aquifer test site provide a basis for characterization and verification of hydraulic, thermal, geophysical, microbiological, and geochemical process understanding. A HT-ATES system was experimentally simulated at the field site, representing three phases with varying loading and unloading cycles at injection temperatures of 80°C. More than 500 thermocouples were used to record temperature data over a 579-day period between July 2021 and February 2023. A total of eleven operating cycles divided into three phases were performed, representing a total heat input of 155 MWh. The temperature records are highly resolved spatially, especially in the vicinity of the injection well, with intervals as low as 0.5 m in the vertical and horizontal directions, and a temporal resolution of 10 min. Thus, the temperature distribution in the subsurface and the position of the heat plume is well characterized at any time. Results show, that the temperature distribution is affected by density driven convection, caused by the temperature differences, as well as heat loss to the confining unit. The storage efficiency was determined by measuring return flow rates and temperatures, showing that storage efficiency decreases with cycle length and with downtimes between charging and discharging.

description:
Sphalerite (ZnS) is the main ore mineral in clastic-dominant (CD-type) massive sulfide deposits. However, the precise physicochemical conditions of ore formation are often poorly constrained. This study uses sphalerite mineral chemistry and fluid inclusion microthermometry to constrain conditions of Zn mineralization at the Boundary Zone prospect of Macmillan Pass district, Canada.

The sulfide mineralization comprises pyrite, sphalerite, galena, and minor chalcopyrite. Sphalerite with contrasting trace element compositions is hosted in Late Ordovician-Early Silurian (Duo Lake Formation) and Late Devonian (Portrait Lake Formation) black mudstones. Different paragenetic stages of sphalerite formation preserve distinct trace element patterns within and between host rock intervals, and overall, Ge, Ga, Cu, and Cd, are relatively enriched compared to In. Trace element incorporation mechanisms vary, with both direct and coupled substitution (e.g., 3Zn2+ ↔ (Ge)4+ + 2Cu+) pathways suggestive of compositional and fluid temperature differences during sphalerite precipitation.

Homogenization temperatures (Th) of CO2-N2-bearing, 2-phase primary aqueous fluid inclusions in Portrait Lake sphalerite range between 154 – 249°C (median= 179°C). The Th values of quartz-hosted CO2-N2-H2S-CH4-bearing aqueous inclusions from late veins are in the range of 207 – 236°C (median= 223°C). These temperatures are consistent with sphalerite trace element geothermometry (GGIMFis; 163 – 279°C) and are comparable to nearby Tom and Jason CD-type deposits in the Macmillan Pass district.

description:
The study area, Erbil Central Sub-Basin, is located within the foothill zone in the stable shelf tectonic unit of Iraq (northern Iraq) on the Arabian plate. Recently, groundwater demand has increased significantly due to insufficient surface water resources for agricultural, industrial, and domestic water uses depending on ever-increasing socio-economic development and population in the study area. Sampling studies were carried out in two different periods, May 2020 (wet season) and September 2020 (dry season), to determine the water quality in water resources located throughout the sub-basin. For this purpose, a total of 30 samples, including 27 groundwater wells, and 3 wastewater samples from channels, were collected and analyzed. The general hydrochemical analysis indicates that overall well water quality is suitable for drinking purposes except where elevated NO3, COD, and BOD5 concentrations are found. Most trace metal analysis results (except for Fe) in wells and wastewater channels show that they are below the permissible limits (0.3 mg/L) from IQWS (2010) and WHO guidelines (2011). The results of the factor analysis for the wet and dry season hydrogeochemical indicate that the first five and six-component extracted have eigenvalues>1 and correspond to approximately 94.844 and 96.26 % of the total variance, respectively. The factor analysis indicated that groundwater quality in the wet and dry season are significantly associated with anthropogenic pollution sources such as leaching from soil layers, cesspools wastes, industrial wastes, and agriculture activities rather than natural, geogenic processes such as reverse ion exchange, the weathering of carbonate minerals from geologic formations outcropping throughout the Erbil Central Sub-Basin.

description:
The Koralm Complex in eastern Austria comprises various gneisses and eclogite lenses which record high-pressure metamorphism of Late Cretaceous age, acquired in an intracontinental subduction zone. The mechanism of exhumation of the Koralm Complex is either slab extraction or wedge extrusion. The present study aims at adding structural evidence to this problem. We studied an WSW-ESE-striking shear zone with SSE-dipping foliation and subhorizontal stretching lineation in the central part of the Koralm Complex. Based on quartz crystallographic preferred orientations (CPO) in gneiss, Krohe (1987) demonstrated sinistral shearing in this shear zone. We investigate microstructure and CPO of samples from the same shear zone using electron backscatter diffraction and photometry. Microstructures indicate grain-boundary migration, subgrain rotation, and static annealing. We find sinistral as well as dextral shear sense. This may either reflect flattening in the shear zone or two phases of deformation with contrasting kinematics. These two possibilities are discussed based on the textural data.

description:
The sequence stratigraphic and facies analyses of the Lower Cenomanian to Upper Turonian core section HG 7025 provide a new standard section of the regional facies development and stratigraphic architecture in the so-called “Faziesübergangszone” (facies transition zone) of the Saxonian Cretaceous Basin. The section covers eight depositional sequences, divided by nine sequence-bounding sedimentary unconformities (SBs). The Lower Cenomanian depositional sequences DS Ce 1+2 and DS Ce 3 comprise the lower and upper fluvial Niederschöna Formation, separated by sequence boundary SB Ce 2. Above SB Ce 3, the Middle Cenomanian Wurmsandstein (DS Ce 4) displays the first marine influence in the succession. Intensifying this trend, the marine onlap continues during the early Late Cenomanian DS Ce 5, almost completely levelling the pre-existing paleo-topography. DS Ce 5 ends at SB Ce 5, representing a subaerial unconformity. Cenomanian marine onlap is completed by the plenus transgression during DS Ce-Tu 1, culminating in the lowermost Turonian Lohmgrund Horizon. The transition from Lower to Middle Turonian is marked by the regionally correlatable Bielatal Horizon of the Schmilka Formation (SB Tu 1). Both early Middle Turonian DS Tu 2 and Middle to early Late Turonian DS Tu 3 are defined by rapid sea-level rises and subsequent pronounced progradation phases. Separated by a subaerial unconformity (SB Tu 3), DS Tu 4 comprises a trans-/regressive cycle capped by SB Tu 4, marked by a sharp grain-size increase at the base of Sandstein c3. The Late Turonian DS Tu 5 is only represented by lowstand and early transgressive deposits.

description:
The amount of digital subsurface and geoscience data has grown exponentially over the past few decades with many companies, researchers and government organizations dealing with rapidly growing Petabyte-scales of data. On the other hand, hardware, storage solutions, technical applications and data management utilities have not kept up with these developments. This has resulted in a big gap and hampers the use of AI and data-driven workflows in complex subsurface projects, be it in hydrocarbon exploration and development, geothermal energy projects, CCS, H2-exploration & storage and the search for nuclear waste sites, but also integrated scientific research programs.

The Open Subsurface Data Universe (OSDUTM) project aims to address these critical challenges and has already resulted in fundamental changes to the way data is managed. OSDUTM is a consortium of over 230 companies and organizations that pool their expertise in geoscience, software development, data center management and associated services to address the challenges via an open-source and cloud-agnostic data platform. Government organizations, geological surveys and universities are also participating in the project. The main drivers behind geoscience data standardization and separating data from applications are the expected benefits for integration, simplification and automation of complex subsurface modelling and project workflows as well as the facilitation of AI/ML opportunities enabled via the data platform.

This talk will demonstrate why subsurface data and the OSDUTM data platform will play a critical role in the energy transition towards net zero emissions with the subsurface as a key component - even after the era of hydrocarbons.

description:
For successful and safe underground CO2 storage, a profound knowledge of the subsurface and its geological structures characterizing the selected reservoir is essential. Besides robust geological models and storage capacity estimations, seal integrity analysis and the identification of potential seal-bypass systems is crucial to ensure save long-term storage of CO2 in the deep subsurface. Within the framework of the GEOSTOR project, we assess potential Triassic and Jurassic CO2 reservoirs by analysing the integrity of overlying barrier formations below the German North Sea. For this purpose, we use recently acquired high-resolution 3D seismic data covering an area of 94 km² within the northwestern German North Sea (“Entenschnabel”) and high-resolution 2D seismic data from the central German North Sea (“West Schleswig Block”) covering a total length of about 1500 km. Seismic amplitude anomalies indicate the presence of fluids allowing the investigation of former fluid migration pathways and their connection to faults and salt structures. First results from the “Entenschnabel” show a highly resolved 3D image from the seafloor to the Zechstein covering the salt diapir Belinda. Bright spots indicate fluid migration along the crestal fault system. Direct fluid migration indicators are scarce within the West Schleswig Block. Locally, bright spots indicate fluid migration along crestal faults of salt structures. We compare and discuss the characteristics of identified fluid migration pathways near the salt diapir Belinda with fluid migration and its correlation with faults and salt structures from the central German North Sea in the context of barrier integrity for subsurface CO2 storage.
The peer comic book project : illustrating peer workers’ experiences working throughout the overdose crisis in the suburban Lower Mainland

description: Several regions of North America and Europe are experiencing a devastating drug overdose epidemic. In Canada, the province of British Columbia (BC) has the highest death rates due to drug toxicity. Peer workers, people with lived and living experience with substance use who use that lived experience in their professional work, are at the frontlines of responding to the overdose crisis through roles such as peer-witnessing of substance use, outreach services, mobile overdose response, delivery and collection of harm reduction supplies, and advocacy. Whilst peer workers have been the subject of interdisciplinary scholarship which examines their utility to harm reduction initiatives and their workplace conditions, they have not yet been involved in arts-based collaborative projects. This thesis examines an arts-based collaboration rooted in tenets of Participatory Action Research (PAR) and Values-Based Cartooning in which I worked with three peer workers from the suburban Lower Mainland to create a series of graphic vignettes. The comic strips reflect peers’ experiences working throughout the overdose crisis within contexts of escalating street violence, deepening socioeconomic inequities, and pervasive instances of drug poisoning. I describe the intricacies of collaboration between an academic researcher and people who use(d) substances, including the effects of deeply entrenched power dynamics, processes of analysis and reflection, and the capacity of art-based projects to elicit nuanced manifestations of agency and power. This thesis describes both the strengths and downfalls of an arts-based collaboration and offers practical insights for future projects.

description: Irregular control-flow structures like deeply nested conditional branches are common in real-world software applications. Improving the performance and efficiency of such programs is often challenging because it is difficult to analyze and optimize programs with irregular control flow. We observe that real-world programs contain similar or identical computations within different code paths of the conditional branches. Compilers can merge similar code to improve performance or code size. However, existing compiler optimizations like code hoisting/sinking, and tail merging do not fully exploit this opportunity. We propose a new technique called Control-Flow Melding (CFM) that can merge similar code sequences at the control-flow region level. We evaluate CFM in two applications. First, we show that CFM reduces the control divergence in GPU programs and improves the performance. Second, we apply CFM to CPU programs and show its effectiveness in reducing code size without sacrificing performance. In the next part of this dissertation, we investigate how CFM can be extended to improve dynamic test generation techniques like Dynamic Symbolic Execution (DSE). DSE suffers from path explosion problem when many conditional branches are present in the program. We propose a non-semantics-preserving branch elimination transformation called CFM-SE that reduces the number of symbolic branches in a program. We also provide a framework for detecting and reasoning about false positive bugs that might be added to the program by non-semantics-preserving transformations like CFM-SE. Furthermore, we evaluate CFM-SE on real-world applications and show its effectiveness in improving DSE performance and code coverage.

description:
The examination of more than 500 samples of worldwide carbonatites on the basis of Sr-Nd isotope systematics allows dividing them into three groups which do not follow conventional grouping. Carbonatites with a mantle signature and variable amounts of incorporated sedimentary material form the first two groups. The carbonatites in the third group have resolvedly lower 143Nd/144Nd signatures at a given eSr(i) value that cannot easily be explained by crustal contamination but rather by derivation of carbonatite parental melts from the mantle source metasomatized by 2-6% of slab-derived melts with low Sm/Nd during the late Archean (~2.7 Ga).

                As a consequence of high concentrations of Sr and Nd, this system is more resilient to overprint compared to Re-Os elemental and isotope systematics. Overall, 44 carbonatite samples were investigated for Re–Os compositions; of these, 15 samples were excluded due to modification by late-stage hydrothermal alteration. The remaining carbonatites still yield a wide range of gOs from ~4 to 4000. Whether this wide range is a result of the presence of recycled crust or originates from previous carbonatite metasomatism remains unclear.

                Extremely low concentrations of highly siderophile elements (HSE) in carbonatites and common nugget effects observed are the result of the behavior of sulfur-bearing phases as the main HSE carrier and oxygen fugacity. Carbonated silicate melts are capable to host significant amounts of PGE but during ascent, S-rich magma will separate from carbonatite melts leading to the sequestration of PGE due to higher distribution coefficients, leaving carbonatite melt depleted in PGE.

description:
Climate projections indicate that extreme weather events have increased in frequency and intensity in the past and will affect sensitive Germany in the near future. Our study site, the catchment of the lower Spree, is located in Brandenburg. The region is affected by water stress showing a water deficit of 80 Mio. m3 on an area of 3500 km2 with many competing water users. Our goal is to investigate the impact of shifts in climate, land use and vegetation on recharge and available groundwater resources. In four different catchments with different characteristics we monitor groundwater und lake levels, stream discharge, and depth dependent soil moisture. Isotopic composition of precipitation, groundwater, and surface water is investigated to calculate water fluxes between different compartments. Electrical conductivity down to a depth of 200m below surface is recorded. Measured NaCl concentrations reach up to 10 – 15 g/kg. Employing the hydrological model SWAT evapotranspiration, discharge and soil moisture are calibrated to calculate long-term groundwater ranges pattern, which ranges in average at 77 mm/a. The M-K test shows decreasing recharge from May to August, an increase from December to February, and almost no change from September to November leading to an overall decreasing trend over the last 20 years. We are planning to derive concepts for areas with highest economic or ecological value derived from socio-economic analyses for the implementation of artificial recharge using greywater, treated waste water or storm water to replenish the groundwater deficit and to retain uplift of the saline groundwater water.

Percutaneous nephrostomy versus retrograde ureteral stent in adult patients with malignant ureteral obstruction : comparing changes in the renal function and clinical outcomes
Creators: name: Eshumani, Walid

description: Background: Urinary diversion (UD) in malignant ureteral obstruction (MUO) is required to relieve symptoms, initiate systemic therapies, and save lives, especially in bilateral ureteral obstruction. Percutaneous nephrostomy (PCN) and retrograde ureteral stent (RUS) are the most common interventional methods. However, these interventional methods' success, efficacy, and complication rates vary. Methods: Clinical outcomes and changes in renal function following UD in patients with MUO treated at Vancouver General Hospital (VGH) from January 2015 to October 2021 were analyzed retrospectively. A total of 159 patients were identified, of whom 81 underwent PCN (38 males (46%) and 43 females (53%), mean age ± SD 65.7± 12.9 years, range 35 to 95 years) and 78 underwent RUS insertion (27 males (35%) and 51 females (65%), mean age 66.4 ± 13.1 years, range 24 to 90 years). Renal function changes were compared between the two groups using serum creatinine and estimated glomerular filtration rate (eGFR) data at baseline, at intervention, and at different time points after intervention (1 week and 1,3,6, and 12 months). Clinical endpoints assessed included the success rate of UD, procedural complications, and the need for another UD method. Results: The renal function was comparable between the two study arms except at the time of the intervention, in which the PCN median creatinine was 290 vs 127 in the RUS (p <0.001) and median eGFR 17 vs 44 (p<0.001). The success rate of intervention was high in both groups and there was no statistically significant difference (97.9% in the PCN group and 93.5% in RUS group (p=0.104)). Compared to the PCN group, the RUS group had a higher rate of residual hydronephrosis following intervention (55% vs 17%, p <0.001), however, residual hydronephrosis was not associated with serum creatinine levels (correlation coefficient 0.075, p=0.419). Complications in the two groups were comparable (PCN 50.6% vs RUS 50%, p=0.367). The median overall survival for all MUO patients was 12.1 months. It was 11.4 months in the PCN group and 13.3 months in the RUS group (p=0.480). Conclusion: PCN and RUS are safe and effective UD methods for decompressing kidneys affected by MUO.

description: Tussen 1500 en 1900 verschilden de maaltijden danig van deze die we op heden kennen. Wat men zoal verorberde op de site Vrouwenhove en later op Sabbe’s Hof wordt door Hendrik Demiddele uiteen gezet uitgaande van de gevonden plantaardige en dierlijke resten. Spijzen en dranken kwamen op tafel in vormen van eet- en drinkgerei. Oorspronkelijk bestonden de tafels uit smalle losse planken op schragen. Men at doorgaans op houten of tinnen snijplankjes of op borden. Ook brood kon als onderlegger dienen. Naar gelang een armer of rijker milieu dronk men uit aarden potten, glazen of metalen bekers en drinknappen.
