Object detection in camera images, using deep learning has been proven successfully recent years. Rising rates and computationally efficient network structures are pushing this technique towards application production vehicles. Nevertheless, the sensor quality of is limited severe weather conditions through increased noise sparsely lit areas at night. Our approach enhances current 2D object networks by fusing data projected sparse radar layers. The proposed CameraRadarFusion Net (CRF-Net)...
Abstract. In alpine terrain, snow sublimation represents an important component of the winter moisture budget, representing a proportion precipitation which does not contribute to melt. To quantify its amount we analyze spatial pattern at ground, from canopy and turbulent suspension during wind-induced transport for high area in Berchtesgaden National Park (Germany), discuss efficiency these processes with respect seasonal snowfall. Therefore, utilized interpolated meteorological recordings...
Abstract The water balance of Alpine regions is strongly determined by the storage in form snow and ice On basis long time series daily precipitation, air temperature discharge, conceptual runoff model HBV3–ETH9 was applied to various basins eastern Alps showing a glacierization 0–80%. Using results regional climate modelling under assumption doubling C0 2 , meteorological input data files were altered taking into account more frequent hot days additional connective precipitation events...
Abstract. Water supply of most lowland cultures heavily depends on rain and melt water from the upstream mountains. Especially melt-water release alpine mountain ranges is usually attributed a pivotal role for large downstream regions. scarcity assumed as consequence glacier shrinkage possible disappearance due to global climate change (GCC), in particular parts Central Southeast Asia. In this paper, application validation coupled modeling approach with regional model (RCM) outputs...
Climate change has a large impact on water resources and thus hydropower. Hydroelectric power generation is closely linked to the regional hydrological situation of watershed reacts sensitively changes in quantity seasonality. The development hydroelectric Upper Danube basin was modelled for two future decades, namely 2021–2030 2051–2060, using special hydropower module coupled with physically-based model PROMET. To cover possible range uncertainties, 16 climate scenarios were taken as...
A conceptual precipitation–runoff model was applied in five glacierized catchments Central Asia. The model, which first developed and the Alps, works on a daily time step yields good results more continental climate of Tien Shan mountains for present-day conditions. Runoff scenarios different climates (doubling CO2) glacierization conditions predict an increased flood risk as stage complex picture after complete glacier loss: higher discharge during spring due to earlier intense snowmelt is...
Abstract. A comprehensive hydrometeorological and glaciological data set is presented, originating from a multitude of glaciological, meteorological, hydrological laser scanning recordings at research sites in the Rofental (1891–3772 m a.s.l., Ötztal Alps, Austria). The sets span period 150 years hence represent unique time series rich high-altitude mountain observations. Their collection was originally initiated to support scientific investigation glaciers Hintereisferner, Kesselwandferner...
Cold plasma-based ionization techniques allow for soft of a wide variety chemical compounds. In this mechanism, the atmosphere plays crucial role in ionization. Knowing its influence is critical optimization analysis conditions and interpretation resulting spectra. This study uses by reaction transfer (SICRIT), variant dielectric barrier discharge (DBDI), that allows controlled to investigate dopant effects. The eight makeup gas compositions (dry nitrogen, room air, nitrogen-enriched with...
Abstract In this study, long-term series of winter mass balances from two neighbouring glaciers in the southern Oetztal Alps, Austria, i.e. Hintereisferner and Vernagtferner, are analyzed with respect to methods used their determination. For purpose, (1) some basic data field surveys presented, (2) influence different temporal systems is discussed, (3) profile, contour a ‘model’ method based on energy-balance ablation modelling measured net balance discussed reliability resulting series.

The use of liquid chromatography coupled with high-resolution mass spectrometry (LC–HRMS) has steadily increased in many application fields ranging from metabolomics to environmental science. HRMS data are frequently used for nontarget screening (NTS), i.e., the search compounds that not previously known and where no reference substances available. However, large quantity produced by NTS analytical workflows makes interpretation time-dependent monitoring samples very sophisticated...
A novel biomaterial consisting of the biodegradable compounds hydroxyapatite, chitosan and starch was developed. Hydroxyapatite particles were modified in a layer-to-layer reaction with oxidised deacetylated chitosan. In this manner, two kinds different surfaces generated, one featuring chitosan, other exhibiting at outermost layer. Mixed together, these form homogeneous powder, which can be transformed into paste by adding water. contact water amino groups aldehyde Schiff's base bonding...
Glacier mass-budget monitoring documents climate fluctuations, provides context for observed glacier-geometry changes, and can provide information on the glaciers' states. We examine series available geometries of three well-documented glaciers located in same catchment area less than 10 kilometers from one another Austrian Ötztal Alps. The altitudinal profiles 1981–2010 average specific mass budgets each glacier serve as climatic reference. apply these reference all geometries, thereby...

Cannabinoids exert neuroprotective and symptomatic effects in amyotrophic lateral sclerosis (ALS). We assessed the pharmacokinetics (PK) tolerability of delta-9-tetrahydrocannabinol (THC) ALS patients.Nine patients received THC single oral doses 5mg 10mg, separated by a wash-out period two weeks. Blood samples for determination THC, 11-nor-9-carboxy-THC (THC-COOH) hydroxy-THC (THC-OH) were taken up to 8 hours after intake. Adverse events visual analogue scales (VAS). Plasma concentrations...
Current legislations typically characterize systems of aerosols, such as from vehicle exhaust, primarily by number concentration and size distributions. While potential health threats have a dependence on the particle size, chemical composition particles, including volatile semi-volatile components adsorbed onto nonvolatile cores present at roadside urban settings, is important in understanding impact exhaust particles health. To date, only tools suitable for an online in-depth aerosol...
