A miniaturized method for fast, simple, and sensitive pesticide analysis in soils
; ; ; ; ; (Journal of Soils and Sediments, 2021-10-18)
Purpose: Organochlorine pesticides (OCPs) like lindane and DDT have been used extensively after World War II until the 1990s. Still, residues of these pesticides can be found in agricultural soils all over the ... -
A model ensemble approach to determine the humus building efficiency of organic amendments in incubation experiments
; Diel, Julius; Nielsen, Kerstin; Mewes, Paul; Engels, Christof; Franko, Uwe (Soil Use and Management, 2021-02-02)
Organic amendments are important to sustain soil organic matter (SOM) and soil functions in agricultural soils. Information about the contribution of organic amendments to SOM can be derived from incubation experiments. ... -
A model ensemble generator to explore structural uncertainty in karst systems with unmapped conduits
; ; ; ; (Hydrogeology Journal, 2020-10-02)
Karst aquifers are characterized by high-conductivity conduits embedded in a low-conductivity fractured matrix, resulting in extreme heterogeneity and variable groundwater flow behavior. The conduit network controls ... -
A modified Mask region‐based convolutional neural network approach for the automated detection of archaeological sites on high‐resolution light detection and ranging‐derived digital elevation models in the North German Lowland
; Eltaher, Mahmoud; ; Breuß, Michael; Raab, Alexandra; Schneider, Anna (Archaeological Prospection, 2021-02-02)
Due to complicated backgrounds and unclear target orientation, automated object detection is difficult in the field of archaeology. Most of the current convolutional neural network (CNN) object‐oriented detection techniques ... -
A modular graph transformation rule set for IFC‐to‐CityGML conversion
; Lim, Joie; (Transactions in GIS, 2021-01-20)
Conversion of Industry Foundation Classes (IFC) building models into CityGML city models is one of the operational scenarios for BIM–GIS integration, with a variety of applications producing and consuming data on either ... -
A multi‐criteria decision‐making approach for assembling optimal powertrain technology portfolios in low GHG emission environments
; ; (Journal of Industrial Ecology, 2021-05-13)
Environmental regulations force car manufacturers to renew the powertrain technology portfolio offered to the customer to comply with greenhouse gas (GHG) emission targets. In turn, automotive companies face the task of ... -
A multi‐parameter approach to quantify riverbed clogging and vertical hyporheic connectivity
; ; ; ; ; ; (River Research and Applications, 2023-04-26)
Abstract Riverbed clogging is key to assessing vertical connectivity in the hyporheic zone and ...

A myricaceous male inflorescence with pollen in situ from the middle Eocene of Europe
(Palaeobiodiversity and Palaeoenvironments, 2021-04-28)The late middle Eocene lacustrine filling of a maar lake at Eckfeld (Eifel Hills, Rhineland-Palatinate, western Germany) has provided four specimens of male inflorescences (catkins) in different stages of anthesis, each ... -
A new "deep-water" Chaetetopsis Species (Chaetetopsis favositiformis n. sp., Demospongiae) from the Plattenwald Bed (Mid-Cretaceous Garschella Formation, Vorarlberg, Austria)
; Föllmi, Karl B. (Eclogae geologicae Helvetiae, 1991)

A new algorithm to retrieve the sea ice concentration using weather-corrected 85 GHz SSM/I measurements
(Univ. Bremen, 2001)Sea ice is a very important component of the climate system. While the Arctic sea ice extent has retreated during the past 20 years, it has remained constant in the Antarctic. In order to better understand the role of sea ... -
A new analysis approach for long-term variations of forest loss, fragmentation, and degradation resulting from road-network expansion using Landsat time-series and object-based image analysis
; ; (Land Degradation & Development, 2020)
Despite facilitating transport by low-volume roads for multiple purposes, these roads also open corridors to the remote pristine forests and accelerate forest dynamics with deleterious consequences to the forest functionalities ... -
A new approach to classification of 40 years of Antarctic sea ice concentration data
; ; Friedl, Peter; Jacobeit, Jucundus (International Journal of Climatology, 2020-10-21)
In this paper, we present a characterization of Antarctic sea ice based on the classification of annual sea ice concentration (SIC) data from 1979 to 2018. A clustering algorithm was applied to provide a climatological ... -
A new calcitic Sphinctozoan sponge belonging to the demospongiae from the Cassian formation (Lower Carnian; Dolomites, northern Italy) and its phylogenetic relationship
(Geobios, 1987)
A new species of a coralline sponge, Cassianothalamia zardinii n. gen. n.sp., from the Lower Carnian Cassian Beds (northern Italy) is described. The new species possesses a secondary thalamid basal skeleton with a ... -
A New Chronostratigraphy of the Late Weichselian Loess Units in Middle Europe based on Thermoluminescence Dating

A new concept for estimating the influence of vegetation on throughfall kinetic energy using aerial laser scanning
; ; ; ; Schmidtlein, Sebastian (Earth Surface Processes and Landforms, 2020-02-17)
Soil loss caused by erosion has enormous economic and social impacts. Splash effects of rainfall are an important driver of erosion processes; however, effects of vegetation on splash erosion are still not fully understood. ... -
A new concept for temporal gating of synchrotron X‐ray pulses
(Journal of Synchrotron Radiation, 2021-02-05)A new concept for temporal gating of synchrotron X‐ray pulses based on laser‐induced thermal transient gratings is presented. First experimental tests of the concept yield a diffraction efficiency of 0.18%; however, the ... -
