Abstract

Karst aquifers provide drinking water for 10% of the world's population, support agriculture, groundwater-dependent activities, and ecosystems. These aquifers are characterised by complex groundwater-flow systems, hence, they are extremely vulnerable and protecting them requires an in-depth understanding of the systems. Poor data accessibility has limited advances in karst research and realistic representation of karst processes in large-scale hydrological studies. In this study, we present World Karst Spring hydrograph (WoKaS) database, a community-wide effort to improve data accessibility. WoKaS is the first global karst springs discharge database with over 400 spring observations collected from articles, hydrological databases and researchers. The dataset's coverage compares to the global distribution of carbonate rocks with some bias towards the latitudes of more developed countries. WoKaS database will ensure easy access to a large-sample of good quality datasets suitable for a wide range of applications: comparative studies, trend analysis and model evaluation. This database will largely contribute to research advancement in karst hydrology, supports karst groundwater management, and promotes international and interdisciplinary collaborations.

Abstract

Declining foliar phosphorus (P) levels call increasing attention to the cycling of this element in temperate forests. We explored the fluxes of P in a temperate mixed deciduous forest ecosystem in six distinct hydrological compartments: Bulk precipitation and throughfall, soil water draining laterally from three different soil depths (0–15, 15–150, 150–320 cm below soil surface), groundwater, creek and spring discharge, which were sampled at daily to bi-weekly resolution from March 2015 to February 2016. Atmospheric P fluxes into the ecosystem were equally partitioned between wet and dry deposition. Approximately 10% of the foliar P stock was lost annually by foliar leaching during late summer. The concentrations of dissolved P in soil water from the forest floor and upper mineral topsoil followed a pronounced seasonal cycle with higher concentrations during the vegetation period. The concentrations of P dissolved in soil water decreased with increasing soil depth. Using an end member mixing analysis (EMMA) we found that P sources feeding the spring water were both soil water from greater depths or groundwater with season specific contributions. Atmospheric P fluxes into the ecosystem determined in this study and P-release from weathering reported for the research site were large enough to compensate P losses with runoff. This suggests that declining foliar P levels of forests are unlikely the result of a dwindling total P supply, but rather caused by tree nutrition imbalances or alternative stressors.

However, in most of the aforementioned approaches, such optimization is focused on specific compounds, or compound classes, known to be present and/or abundant in the corresponding matrices [3,4]. Detection and chemical identification of organic biomarkers require the use of high-sensitivity techniques to overcome the complexity limitations of the samples in terms of composition and low concentrations of constituent compounds. The analysis of autumn heather honey revealed that phenolic compounds are the most abundant and p-anisaldehyde, 1-methoxy-4-propyl-benzene, and p-anisic acid could serve as potent marker compounds. These compounds were distributed in five major categories, namely, hydroxycinnamic acid derivatives (10 compounds), hydroxybenzoic acid derivatives (6 compounds), flavonoids (25 compounds), phenolic terpenes (carnasol and carnosic acid), and chalcones (arbutin).

Abstract

3D printing has been integrated in various applications in biomedical and medical imaging. A prominent new field is that of radiation protection and shielding, where the introduction of infused filaments makes it possible to manufacture customized 3D printed shielding. In this study we examine the use of a Polylactic Acid (PLA) infused with tungsten to shield a Positron Emission Tomography / Computer Tomography (PET/CT) scanner. The goal is to reduce the effects of the radiation emitted from outside the field-of-view (FOV) on the PET image and to protect the PET electronics against the X-rays from the CT. The shielding properties were examined using the radioactive sources Ba-133, Na-22, and Cs-137, as well as two X-ray sources with energy ranging from 20 to 125 kV. For X-rays below 40 kV, less than 1 cm of the tungsten infused shielding was sufficient to block more than 95% of the X-ray beam intensity. However, only around 30% of the 511-keV rays from Na-22 was attenuated by 3.5 cm of the 3D printed material. Our results support the application of tungsten infused PLA materials to shield the PET electronics. However, further studies are required to determine if shielding the PET crystals with tungsten infused PLA can improve image quality by reducing the contribution of scattered rays from outside the FOV. Additionally, our results show new possibilities for the use of infused filament in the field of Xray imaging. For example, where lead coverings or skirts are excessively bulky or rigid, it could be employed to optimize shielding for radiation-sensitive organs.
