description: A numerical method ADER-DG with a local DG predictor for solving a DAE system has been developed, which was based on the formulation of ADER-DG methods using a local DG predictor for solving ODE and PDE systems. The basis functions were chosen in the form of Lagrange interpolation polynomials with nodal points at the roots of the Radau polynomials, which differs from the classical formulations of the ADER-DG method, where it is customary to use the roots of Legendre polynomials. It was shown that the use of this basis leads to A-stability and L1-stability in the case of using the DAE solver as ODE solver. The numerical method ADER-DG allows one to obtain a highly accurate numerical solution even on very coarse grids, with a step greater than the main characteristic scale of solution variation. The local discrete time solution can be used as a numerical solution of the DAE system between grid nodes, thereby providing subgrid resolution even in the case of very coarse grids. The classical test examples were solved by developed numerical method ADER-DG. With increasing index of the DAE system, a decrease in the empirical convergence orders p is observed. An unexpected result was obtained in the numerical solution of the stiff DAE system -- the empirical convergence orders of the numerical solution obtained using the developed method turned out to be significantly higher than the values expected for this method in the case of stiff problems. It turns out that the use of Lagrange interpolation polynomials with nodal points at the roots of the Radau polynomials is much better suited for solving stiff problems. Estimates showed that the computational costs of the ADER-DG method are approximately comparable to the computational costs of implicit Runge-Kutta methods used to solve DAE systems. Methods were proposed to reduce the computational costs of the ADER-DG method.

description: Ship hydrodynamics in a constant waterway have been well studied. With a coordinate system fixed on the moving ship, the boundary value problem (BVP) is usually treated as a steady one. However, the hydrodynamics of a ship moving in confined waterways with abrupt changes in width or depth are complex due to their unsteady nature. The studies on such unsteady problems are insufficient. In the engineering practise, the hydrodynamic unsteadiness can be fully reflected by a scenario when a ship enters a lock. Prior studies have predominantly focused on predicting the ships’ hydrodynamic forces without considering the unsteady terms on the free-surface boundary conditions. Obviously, such steady or quasi-steady methods overlooked the crucial unsteady phenomenons on free water surface. To address this gap, the present study introduces a novel three-level difference scheme to discretize the free surface condition, preserving unsteady terms while maintaining temporal continuity of cells on the free surface. With the implementation of such fully unsteady BVP, we observed some interesting unsteady free surface motions which were not well documented in the existing literature. To verify our new observations, as well as to validate the numerical method proposed in this study, two physical model tests were designed and conducted in a towing tank: a submerged ellipsoid enters into a deep lock at relatively high speeds, and a box enters into a shallow and narrow lock at very low speeds. The discussions are highlighted on the unsteady waves in front of the moving bodies, as well as the unsteady resistance induced by such waves.

description: Many oil hydrocarbons are thought to be a source of toxicity in the marine environment. The Baltic Sea, one of the largest bodies of brackish water in the world, has numerous point sources for oil pollution. In particular, growing maritime traffic, including oil transportation, and several oil harbours have increased the risk of oil-spills. Between 1992 and 2003, the total hydrocarbon concentrations (THCs) of Baltic subsurface water were determined by fluorescence spectroscopy (UVF). Concentrations ranged from 0.13 to 1.8 ug l–1 as Ekofisk crude oil equivalents. To assure comparability of the results, the values were converted to chrysene equivalents (0.010–0.14 ug l–1). Seasonal dependence of the THCs was evident — the lowest concentration was found during summer in the Bothnian Sea and Bothnian Bay and the highest during winter in the northern Baltic Proper. THCs differed geographically following the amounts of oil discharges, with highest values in the Gulf of Finland, the northern Baltic Proper and the eastern Gotland Basin.

description: In a democracy, a constitutional separation of powers between the executive and the assembly may be desirable, but the constitutional concentration of executive power in a single human being is not. The book defends this thesis and explores ‘semi-parliamentary government’ as an alternative to presidential government. Semi-parliamentarism avoids power concentration in one person by shifting the separation of powers into the democratic assembly. The executive becomes fused with only one part of the assembly, even though the other part has at least equal democratic legitimacy and robust veto power on ordinary legislation. The book identifies the Australian Commonwealth and Japan, as well as the Australian states of New South Wales, South Australia, Tasmania, Victoria, and Western Australia, as semi-parliamentary systems. Using data from 23 countries and 6 Australian states, it maps how parliamentary and semi-parliamentary systems balance competing visions of democracy; it analyzes patterns of electoral and party systems, cabinet formation, legislative coalition-building, and constitutional reforms; it systematically compares the semi-parliamentary and presidential separation of powers; and it develops new and innovative semi-parliamentary designs, some of which do not require two separate chambers.

description: Climate changes and the potential related warming can change runoff, nutrient transport, mean wind velocities and water temperatures. These changes will further affect algal growth in a way that can be modelled. The changes to the nutrient load, temperature regime and algal biomass were simulated by three separate models. The simulations were made for the years 2020, 2050 and 2090. The simulated temperature variations and nutrient loading dynamics were used by algal model to predict changes of the algal biomass under the three different climate scenarios. According to the different scenarios, the maximum temperature of the surface water increased by 0.3–6.2 °C, but in the deeper waters (> 40 m) by less than 0.1 °C. The major part of the nutrient loads is anthropogenic and this part did not change in the scenarios. Thus, the changes in the algal biomass were also relatively small. However, the timing and quantity of spring bloom did change noticeably, at most in 2090, two weeks earlier and 20% higher than nowadays.
Self-consistent electrostatic formalism of bulk electrolytes based on the asymmetric treatment of the short- and long-range ion interactions

Year: 2024
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We predict the thermodynamic behavior of bulk electrolytes from an ionic Hard-Core (HC) size-augmented self-consistent formalism incorporating asymmetrically the short- and long-range ion interactions via their virial and cumulant treatment, respectively. The characteristic splitting length separating these two ranges is obtained from a variational equation solved together with the Schwinger-Dyson (SD) equations. Via comparison with simulation results from the literature, we show that the asymmetric treatment of the distinct interaction ranges significantly extends the validity regime of our previously developed purely cumulant-level Debye-Hückel (DH) theory. Namely, for monovalent solutions with typical ion sizes, the present formalism can accurately predict up to molar concentrations the liquid pressure dominated by HC interactions, the internal energies driven by charge correlations, and the local ion distributions governed by the competition between HC and electrostatic interactions. We evaluate as well the screening length of the liquid and investigate the deviations of the macromolecular interaction range from the DH length. In fair agreement with simulations and experiments, our theory is shown to reproduce the overscreening and underscreening effects occurring respectively in submolar mono- and multivalent electrolytes.

description: We present a novel bounding volume hierarchy for GPU-accelerated direct volume rendering (DVR) as well as volumetric mesh slicing and inside-outside intersection testing. Our novel octree-based data structure is laid out linearly in memory using space filling Morton curves. As our new data structure results in tightly fitting bounding volumes, boundary markers can be associated with nodes in the hierarchy. These markers can be used to speed up all three use cases that we examine. In addition, our data structure is memory-efficient, reducing memory consumption by up to 75%. Tree depth and memory consumption can be controlled using a parameterized heuristic during construction. This allows for significantly shorter construction times compared to the state of the art. For GPU-accelerated DVR, we achieve performance gain of 8.4×–13×. For 3D printing, we present an efficient conservative slicing method that results in a 3×–25× speedup when using our data structure. Furthermore, we improve volumetric mesh intersection testing speed by 5×–52×.

description: Many African countries especially those within the Sahel region are faced with myriad of security challenges. In Nigeria problem of insecurity continues to pose very big challenge to the government; they include banditry, farmer/herders’ conflict, terrorism, kidnapping, armed robbery, and cultism. The insecurity challenges facing Nigeria has overwhelmed the police force, and compelled the federal government to deploy the military to assist the police in fighting crimes. Despite the efforts of the government to strengthen the formal institutions of government to fight crimes and restore peace and safety in the country, insecurity and violent crimes persist. The study, therefore, examines the problem of insecurity, vigilantism and policing in Nigeria. The study relied on secondary sources of data, while the content analysis technique was used to analyse the secondary data. The study found that the prevalence of criminal violence in Nigeria is responsible for the formation of vigilante groups in various parts of the country. The study recommended that the government should tackle some of the socio-economic challenges that breed criminal violence and other social vices such as poverty, unemployment, inequality etc. The study also recommended licensing and training of vigilante groups so as to make them carry out their functions of apprehending criminal deviants without violating their rights
Modeling wind-driven circulation in Lake Ladoga
Creators: name: Beletsky, D.
Publisher: name: Boreal Environment Research Publishing Board
Year: 2001

description: The goal of this paper is to present circulation patterns in Lake Ladoga occurring during episodes of strong wind. Hydrodynamics of episodic events are studied with a three-dimensional barotropic numerical model. Model results are presented for a variety of wind directions and, therefore, can be used for analysis of various biogeochemical data. As an illustration, an analysis of sediment distribution in Lake Ladoga is presented. It is suggested that location of maximum sediment deposition in southeastern Lake Ladoga is due to sediment transport during episodes of strong northwesterly winds. These events generate significant waves in southern Lake Ladoga, causing sediment resuspension and subsequent offshore advection and deposition.

We describe the intrinsic geometry of nondegenerate hypersurfaces in terms of a PDE satisfied by a pair of induced spinors, akin to the generalized Killing spinor equation. Conversely, we prove an embedding result for real analytic pseudo-Riemannian manifolds carrying a pair of spinors satisfying this condition.

description: The energy- and flux budget (EFB) turbulence closure theory for the atmospheric surface layers in convective and stably stratified turbulence has been developed using budget equations for turbulent energies and fluxes in the Boussinesq approximation. In the lower part of the surface layer in the atmospheric convective boundary layer (CBL), the rate of turbulence production of the turbulent kinetic energy (TKE) caused by the mean-flow surface shear and the shear of self-organised coherent structures is much larger than that caused by the buoyancy, which results in three-dimensional turbulence of very complex nature. In the upper part of the surface layer, the rate of turbulence production of TKE due to the shear is much smaller than that caused by the buoyancy, which causes unusual strongly anisotropic buoyancy-driven turbulence. Considering the applications of the obtained results to the atmospheric convective and stably stratified boundary-layer turbulence, the theoretical relationships potentially useful in modelling applications have been derived. In particular, the developed theory for the surface layers in turbulent convection and stably stratified turbulence allows us to determine the vertical profiles for all turbulent characteristics, including TKE, the intensity of turbulent potential temperature fluctuations, the vertical turbulent fluxes of momentum and buoyancy (proportional to potential temperature), the integral turbulence scale, the turbulence anisotropy, the turbulent Prandtl number and the flux Richardson number.

The distribution of heavy metals and arsenic in recent sediments in the Gulf of Finland

Publisher: name: Boreal Environment Research Publishing Board
Year: 1999

description: A large number of sediment samples representing most of the active mud accumulation areas of the Gulf of Finland were studied for total cadmium, chromium, lead, mercury, arsenic, copper and zinc. The highest concentrations of metals were found in sediment surfaces in the easternmost part of the Gulf, which is influenced by the inflow of the Neva river and the loads of the city of St. Petersburg. Vyborg Bay and the Kymi River also clearly affect the off-shore sea bottom. The vertical distributions determined in four sediment cores show for all metals overall decreasing concentrations towards the surface of the sediment cores, which in part indicates decreased load of metals. Evidently levels of copper, lead and mercury are still decreasing, while cadmium and arsenic levels are slowly increasing in the eastern Gulf of Finland. From the mean sedimentation rate of wet suspended particulate matter (SPM) and dry weight of the surficial sediment, an annual accumulation of 8.7 × 106 t a–1 of SPM was estimated for the Gulf. With that estimate the annual total accumulation of elements into the sediments was calculated. The annual accumulations of cadmium and lead are clearly higher in the Gulf of Finland than in the Gulf of Bothnia. Accumulation of the other metals is somewhat higher in the Gulf of Finland, while the accumulation of arsenic is clearly lower, only one fifth of that in the Gulf of Bothnia.

description: The first part of this article studies the collapses of point-vortices for the Euler equation in the plane and for surface quasi-geostrophic equations in the general setting of $α$ models. In these models the kernel of the Biot-Savart law is a power function of exponent $-α$. It is proved that, under a standard non-degeneracy hypothesis, the trajectories of the point-vortices have a Hölder regularity up to, and including, the time of collapse. The Hölder exponent obtained is $1/(α+1)$ and this exponent is proved to be optimal for all $α$ by exhibiting an example of a $3$-vortex collapse.
 The same question is then addressed for the Euler point-vortex system in smooth bounded connected domains. It is proved that if a given point-vortex has an accumulation point in the interior of the domain as $t\to T$, then it converges towards this point and displays the same Hölder continuity property. A partial result for point-vortices that collapse with the boundary is also established : we prove that their distance to the boundary is Hölder regular.

Water quality and fish populations of acid sensitive waters in the Vätsäri area, north-eastern Finland: responses to reduced sulphur emissions from the Kola Peninsula, Russia, in the 1990s

description: Changes in fish population and water quality in response to the decline in sulphur deposition in small waterbodies in north-eastern Finland were studied by using data from two consecutive surveys of fish and water chemistry at 20 sampling sites in 1993 and in 2000. The study area consisted of three separate catchment basins near the Norwegian–Russian border area, 40–50 km west of the nearest large source of SO2, the Nikel industrial complex in the Kola Peninsula. The most common fish species caught were minnow (Phoxinus phoxinus), burbot (Lota lota) and brown trout (Salmo trutta). Special attention was focused on minnow because of its sensitivity to acidification and its frequent occurrence in the study area. At all sampling sites, the alkalinity values of the sampled brooks and lakes were significantly higher and the sulphate concentrations significantly lower in 2000 than in 1993. The increased densities of minnow and changes in the length distribution of the sampled fish indicated that reproduction of the species was successful at most of the sampling sites in the late 1990s. The results suggest that the decrease in acid emissions from the Kola industrial centres has resulted in noticeable chemical and biological recovery of the most acid-sensitive surface waters in north-eastern Finnish Lapland.

description: External surges are a key component of extreme water levels in the North Sea. Caused by low-pressure cells over the North Atlantic and amplified at the continental shelf, they can drive water-level changes of more than 1m at the British, Dutch and German coasts. This work describes an improved and semi-automated method to detect external surges in sea surface time histories. The method is used to analyse tide gauge and meteorological records from 1995 to 2020 and to supplement an existing dataset of external surges, which is used in the determination of design heights of coastal protection facilities. Furthermore, external surges are analysed with regard to their annual and decadal variability, corresponding weather conditions, and their interaction with storm surges in the North Sea. A total of 33% of the 101 external surges occur within close succession of each other, leading to the definition of serial external surges, in which one or more external surges follow less than 72h after the previous external surge. These serial events tend to occur more often during wind-induced storm surges. Moreover, the co-occurrence with a storm surge increases the height of an external surge by 15% on average, highlighting the importance of the consideration of combined events in coastal protection strategies. The improved dataset and knowledge about serial external surges extend the available basis for coastal protection in the North Sea region.

description: Monitoring of clinical trials is a fundamental process required by regulatory agencies. It assures the compliance of a center to the required regulations and the trial protocol. Traditionally, monitoring teams relied on extensive on-site visits and source data verification. However, this is costly, and the outcome is limited. Thus, central statistical monitoring (CSM) is an additional approach recently embraced by the International Council for Harmonisation (ICH) to detect problematic or erroneous data by using visualizations and statistical control measures. Existing implementations have been primarily focused on detecting inlier and outlier data. Other approaches include principal component analysis and distribution of the data. Here we focus on the utilization of comparisons of centers to the Grand mean for different model types and assumptions for common data types, such as binomial, ordinal, and continuous response variables. We implement the usage of multiple comparisons of single centers to the Grand mean of all centers. This approach is also available for various non-normal data types that are abundant in clinical trials. Further, using confidence intervals, an assessment of equivalence to the Grand mean can be applied. In a Monte Carlo simulation study, the applied statistical approaches have been investigated for their ability to control type I error and the assessment of their respective power for balanced and unbalanced designs which are common in registry data and clinical trials. Data from the German Multiple Sclerosis Registry (GMSR) including proportions of missing data, adverse events and disease severity scores were used to verify the results on Real-World-Data (RWD).

title: Investigating the moisture transport associated with extratropical cyclones and the mechanisms that lead to precipitation over the UK
Creators: name: Cuckow, Sophie
Publisher: name: University of Reading
Year: 2024

description: Both atmospheric rivers and the warm conveyor belts of extratropical cyclones have
been linked to heavy precipitation and flooding in the UK. A low-level cyclone-relative moist airflow called the feeder airstream has been shown to transport moisture from the environment ahead of an intense cyclone to the base of the warm
conveyor belt where it rises to form precipitation and enhances the poleward transport of moisture in an atmospheric river.
In this study, the presence of a feeder airstream is investigated using a case study
and a climatology of 1000 storms. The likelihood of a feeder airstream occurring,
and the strength of the feeder airstream in relation to cyclone intensity, propagation
velocity and life-cycle stage is determined. In the case study, a feeder-airstream is
identified during the developing stage of the storm. The feeder airstream is also
identified in the majority of the cyclones in the climatology. However, the strength
of the moisture flux associated with the feeder airstream decreases with a decrease
in maximum intensity, propagation velocity and, in the latter stages of the cyclone
life-cycle.
To quantify the contribution of synoptic scale and micro-scale processes leading to the precipitation associated with the case study, the proportion of rainfall
attributed to cyclone ascent, orographic ascent and the seeder-feeder mechanism
is calculated when the extratropical cyclone with a feeder airstream and an atmospheric river passes over the UK. Modifications to the height of the orography and
the accretion and riming micro-physical processes are made in the Met Office Unified Model. It is found that the majority of the precipitation is produced by cyclone
ascent and the accretion and riming related to the seeder-feeder mechanism. This
suggests that heavy precipitation is formed by a combination of cyclone precipitation
and low-level cloud formation associated with the feeder airstream.

description: The GRACE – Follow On (GRACE-FO) satellite mission (2018-now) hosts the novel Laser Ranging Interferometer (LRI), a technology demonstrator for proving the feasibility of laser interferometry for inter-satellite ranging measurements. The GRACE-FO mission extends the valuable climate data record of changing mass distribution in the system Earth, which was started by the original GRACE mission (2002–2017). The mass distribution can be deduced from observing changes in the distance of two low-earth orbiters employing interferometry of electromagnetic waves in the K-Band for the conventional K-Band Ranging (KBR) and in near-infrared for the novel LRI. This paper identifies possible radiation-induced Single Event Upset (SEU) events in the LRI phase measurement. We simulate the phase data processing within the Laser Ranging Processor (LRP) and use a template-based fitting approach to determine the parameters of the SEU and subtract the events from the ranging data. Over four years of LRI data, 31 of such events were identified and characterized.

description: This paper examines the development of Cambodia’s education regarding the impact of historical global transformation and international influences on its national education policy. It also studies the inclusiveness and generosity of social groups in Cambodia. The paper argues that Cambodia’s education system today is built upon the modern education model established by the French during the colonial period and is developed to combine with its cultural and religious traditions. The socialist regime caused heavy losses to the state and eliminated most of the education facilities. In the past three decades, with support and funds from the international community, Cambodia’s education was reconstructed along with the international standards on education inclusion and generosity.
The role of scientific environmental knowledge in decision-making in the City of Helsinki, Finland
Creators: name: Kansanen, P. H.
Publisher: name: Boreal Environment Research Publishing Board
Year: 2004

description: The effect ecological information has on the decision-making process, largely in connection with traffic planning and land use in the City of Helsinki and its metropolitan area, is evaluated on the basis of some examples of projects. In Finland, significant changes in the environmental legislation have had a positive effect on the decision-making process from the environmental point of view. Planning of the new housing area in Viikki was a positive example in this respect. Even though real alternative assessments in the spirit of EIA principles were not possible to realise, the planners were able to offer alternatives that were based on ecological and other sectors of environmental research that resulted in partly preserving the most valued parts of the landscape and nature for the future. On the other hand, in the Helsinki Metropolitan Area traffic plan the ecological facts played a minor role in decision-making despite a significant amount of various kinds of research, reports and carefully applied EIA principles in the evaluation process of various alternatives. To control the process of building density and to minimise the loss of diversity of the surrounding nature is, from an ecological viewpoint, the greatest challenge to the city planners. This will demand from the researchers up-to-date and reliable information on the current state of the city's natural areas and an effective system to convey the data to the city planners.

description: Dual-type qubits have become a promising way to suppress the crosstalk error of auxiliary operations in large-scale ion trap quantum computation. Here we demonstrate a direct entangling gate between dual-type qubits encoded in the $S_{1/2}$ and $D_{5/2}$ hyperfine manifolds of $^{137}\mathrm{Ba}^{+}$ ions. Our scheme is economic in the hardware, requiring only a single $532\,$nm laser system to entangle both qubit types by driving their Raman transitions. We achieve a Bell state fidelity of $96.3(4)\%$ for the dual-type Molmer-Sorensen gate between an $S$-$D$ ion pair, comparable to that for the same-type $S$-$S$ or $D$-$D$ gates. This technique can reduce the overhead for back-and-forth conversions between dual-type qubits in the quantum circuit with wide applications in quantum error correction and ion-photon quantum networks.

description: A wire-driven parallel robot is a type of robotic system where multiple wires are used to control the movement of a end-effector. The wires are attached to the end-effector and anchored to fixed points on external structures. This configuration allows for the separation of actuators and end-effectors, enabling lightweight and simplified movable parts in the robot. However, its range of motion remains confined within the space formed by the wires, limiting the wire-driven capability to only within the pre-designed operational range. Here, in this study, we develop a wire-driven robot, CubiX, capable of connecting to and utilizing the environment. CubiX connects itself to the environment using up to 8 wires and drives itself by winding these wires. By integrating actuators for winding the wires into CubiX, a portable wire-driven parallel robot is realized without limitations on its workspace. Consequently, the robot can form parallel wire-driven structures by connecting wires to the environment at any operational location.

Gypsum treatment in managing the internal phosphorus load from sapropelic sediments; experiments on Lake Laikkalammi, Finland

description: The sediment of the hypertrophic Lake Laikkalammi, (area 8000 m2, max. depth 13 m) in southern Finland was treated with the industrial by-product Fe-gypsum (CaSO4 x 2H2O) in summer 1998. A 90% reduction of the hypolimnic total phosphorus content was achieved and Secchi disk transparency increased from 50 cm to 270 cm during one year long observation period. Gypsum is hypothesized to limit the internal load through three interacting mechanisms: as a mechanical cover limiting the resuspension and gas ebullition, as a chemical offering binding sites for phosphorus (Ca, Fe) and finally by changing the microbiological composition of sediment by creating more favorable conditions for sulphur bacteria instead of methane bacteria. Fe-gypsum treatment can be seen as a complementary lake restoration method that is suitable for relatively deep, small lakes in which the water quality problems are a consequence of internal loading caused by oxygen deficiency in the hypolimnion.

description: Computer simulation platforms offer an alternative solution by emulating complex systems in a controlled manner. However, existing Edge Computing (EC) simulators, as well as general-purpose vehicular network simulators, are not tailored for VEC and lack dedicated support for modeling the distinct access pattern, entity mobility trajectory and other unique characteristics of VEC networks. To fill this gap, this paper proposes VEC-Sim, a versatile simulation platform for in-depth evaluation and analysis of various service caching and computation offloading policies in VEC networks. VEC-Sim incorporates realistic mechanisms to replicate real-world access patterns, including service feature vector, vehicle mobility modeling, evolving service popularity, new service upload and user preference shifts, etc. Moreover, its modular architecture and extensive Application Programming Interfaces (APIs) allow seamless integration of customized scheduling policies and user-defined metrics. A comprehensive evaluation of VEC-Sim's capabilities is undertaken in comparison to real-world ground truths. Results prove it to be accurate in reproducing classical scheduling algorithms and extremely effective in conducting case studies.
Comprehensive approach to the rehabilitation and management of Vesijärvi, a lake in southern Finland

description: The rehabilitation programme of Vesijärvi, a lake in southern Finland, was commenced in 1987. It has been carried out in three stages: (1) reduction of the external nutrient loading to the lowest possible level, (2) management of the foodweb structure to reduce internal nutrient loading, and (3) measures to maintain the rehabilitated state of the lake. The recovery of Vesijärvi has proven biomanipulation to be an applicable rehabilitation method for large lakes, too. The mechanism behind the recovery was linked to migrations of the dense roach (Rutilus rutilus L.) population that transferred nutrients from the littoral to pelagic zone. Biomanipulation decreased the migrating fish stock and diminished both input and availability of nutrients in pelagic water. Consequently, the productivity of planktonic algae and especially cyanobacteria decreased. To maintain the achieved state, local people have been encouraged to participate in lake and drainage area management. Participation of the key groups (fishermen and farmers) has been enhanced with computer simulation models, which have been used to demonstrate the effects of fisheries and farming practices on the lake. The yield-recruit model and the multispecies value-per-recruit model have helped fishermen in optimising the fisheries to a sustainable level. With the help of the GLEAMS model, farmers have been able to compare the nutrient-loading effects of different field-farming techniques and to choose the less-loading alternatives. The increased participation and cooperation of local people and authorities has been considered to keep the comprehensive management process on a sustainable basis.

description: We prove an elliptic Harnack's inequality for a general form of a parabolic equation that generalizes both the standard parabolic $p$-Laplace equation and the normalized version that has been proposed in stochastic game theory. This version of the inequality doesn't require the intrinsic waiting time and we get the estimate with the same time level on both sides of the inequality.
Comparison and development of ditch structures (bed pipe barriers) in reducing suspended solids concentration in waters flowing from peat mining sites
Creators: name: Kløve, B.

description: Ditch structures are used to reduce the transportation of eroded peat from peat mines during high runoff events. In this article, new types of control structures were compared with traditional ones. Two different experiments were performed under laboratory conditions. First, hydraulics were studied by determining the discharge at different water levels. Second, the effectiveness of the constructed barriers in reducing the transport of peat was measured. The results of the study show that attenuating the runoff peak by storing water in the ditch network is the most effective way of reducing the concentration of suspended solids of waters flowing from peat mining sites. The water intake location also has a small effect on the transport. The new type of control barrier retains the runoff peaks. Its outlet is situated close to the water surface where the concentration of suspended peat is less than at greater depths.

description: The structure of the SARS-CoV-2 spike RBD and human ACE2 as well as changes in the structure due to binding activities were analysed using surface enhanced Raman spectroscopy. The inhibitor cohaerin C was applied to inhibit the binding between spike RBD and ACE2. Differences and changes in the Raman spectra were determined using deconvolution of the amide bands and principal component analysis. We thus demonstrate a fast and label-free analysis of the protein structures and the differentiation between bound and unbound states. The approach is suitable for sensing and screening and might be relevant to investigate other protein systems as well.
