Glacial isostatic contributions to present day sea level change around Greenland
Creators: name: Fleming, Kevin
Publisher: name: GFZ, Helmholtz-Zentrum
Year: 2005

description: Present-day sea-level change around Greenland is examined by assessing the roleplayed by glacial-isostatic adjustment (GIA). We consider the contributions from: (1) the ongoing GIA due to changes in the extent and thickness of the Greenland Ice Sheet (GIS) following the Last Glacial Maximum (LGM), (2) the equivalent signal associated with the continental ice masses located outside of Greenland, and (3) present-day changes in the GIS. Changes in the GIS arising from the last glacial-interglacial transition generally result in falling sea level today. The contribution from ice-load changes outside of Greenland causes rising sea level, owing to Greenland's location on the collapsing forebulge that surrounds the former North American ice sheets. Combining predictions of these contributions gives results showing rising sea level in the southwest and falling sea level in the north and east. However, this is strongly dependent upon the neoglacial part of the GIS's history. The present-day behaviour of the GIS is predicted to cause falling sea level with rates of several mm yr?1 around areas experiencing the larger ice-load changes. The available tide-gauge data are considered unusable by the standards of many workers. Nevertheless, we compare rates of local sea-level change inferred from this type of data with our predictions. In Southern Greenland, where the tide-gauge stations are located, sea level is predicted to be rising at a rate of 4 to 5 mm yr?1. Our predictions match most of the rates obtained from the tide-gauge time series, with the exception of Qaqortoq where the inferred rates may also reect additional oceanic and meteorological effects. Similarly, our predictions are consistent with GPS observations, with again the exception of Qaqortoq.

description: A two-dimensional lattice model with bond disorder is used to investigate the fracture behaviour under stress-controlled conditions. Although the cumulative energy of precursors does not diverge at the critical point, its derivative with respect to the control parameter (reduced stress) exhibits a singular behaviour. Our results are nevertheless compatible with previous experimental findings, if one restricts the comparison to the (limited) range accessible in the experiment. A power-law avalanche distribution is also found with an exponent close to the experimental values.

description: The Hubble tension may introduce a new course of action to revise the standard $Λ$CDM model to unravel dark energy and dark matter physics. The Hubble parameter can be reconstructed by late-time observations of the background evolution model independently. We relate the reconstructed Hubble parameter to the structure formation and large scale structure observables in this work. We use the excursion set theory to calculate the number density of dark matter halos and the mass function of progenitors. We obtain the results for both the Markov and non-Markov extension of the excursion set theory in the context of spherical and ellipsoidal collapse. We show that the number density of dark matter halos in the reconstructed model has approximately $\sim2σ$ difference in comparison to the Planck-2018 $Λ$CDM in the mass range of $M\gtrsim10^{12}M_{\odot}$. We also compare the dark matter halo progenitor mass function with the pair-galaxy statistics and their mass assembly history from observational data of the HST, CANDEL survey. Due to complications to distinguish the ratio of accretion and merger in mass assembly, our result on pair fraction is for illustration only. However, a $\sim5$ times more accurate observations will be promising to distinguish the reconstructed model and the Planck-2018 $Λ$CDM.

description: The spin axes of the mantle, fluid core and solid inner core of the Moon precess at frequency $\Omega_p=2\pi/18.6$ yr$^{-1}$ though with different orientations, leading to viscous friction at the core-mantle boundary (CMB) and inner core boundary (ICB). Here, we use a rotational model of the Moon with a range of inner core and outer core radii to investigate the relative importance of viscous dissipation at the CMB and ICB, and to show how this dissipation is connected to the phase lead angle ($\phi_p$) of the mantle ahead of its Cassini state. We show that when the inner core radius is $>80$ km and the free inner core nutation frequency $\Omega_{ficn}$ approaches $\Omega_p$, viscous dissipation at the ICB can be comparable to that at the CMB, and in the most extreme cases exceed it by as much as a factor 10. If so, the viscous dissipation in the lunar core projected back in time depends on how $\Omega_{ficn}$ has evolved relative to $\Omega_p$. We further show that constraints on the CMB and ICB radii of the lunar core can in principle be extracted by matching the observed phase lead of $\phi_p=0.27$ arcsec; this requires an improved estimate of tidal dissipation and an accurate model of the turbulent viscous torque. Lastly, when our rotational model is constrained to match $\phi_p=0.27$ arcsec, our results suggest that the viscous dissipation at the ICB is likely insufficient to have ever been above the threshold to power a thermally driven dynamo.

description: Analyses of Lunar Laser Ranging data show that the spin-symmetry axis of the Moon is ahead of its expected Cassini state by an angle of $\phi_p$ = 0.27 arcsec. This indicates the presence of one or more dissipation mechanisms acting on the lunar rotation. A combination of solid-body tides and viscous core-mantle coupling have been proposed in previous studies. Here, we investigate whether viscoelastic deformation within a solid inner core at the centre of the Moon can also account for a part of the observed phase lead angle $\phi_p$. We build a rotational dynamic model of the Cassini state of the Moon that comprises an inner core, a fluid core and a mantle, and where solid regions are allowed to deform viscoelastically in response to an applied forcing. We show that the presence of an inner core does not change the global monthly Q of the Moon and hence, that the contribution from solid-body tides to $\phi_p$ is largely unaffected by an inner core. However, we also show that viscoelastic deformation within the inner core, acting to realign its figure axis with that of the mantle, can contribute significantly to $\phi_p$ through inner core-mantle gravitational coupling. We show that the contribution to $\phi_p$ is largest when the inner core viscosity is in the range of $10^{13}$ to $10^{14}$ Pa s, when the inner core radius is large and when the free inner core nutation frequency approaches a resonance with the precession frequency of $2\pi/18.6$ yr$^{-1}$.

description: We report the Chandra detection of resolved X-ray emission of luminosity 3.5 \times 10^{40} ergs s^{-1} (0.4--4.5 keV) and power-law energy spectral index alpha = 1.5 \pm 0.7 from a roughly 10 arcsec length of the north-west radio jet in NGC 315. The X-ray emission is brightest at the base of the radio-bright region about 3 arcsec from the nucleus, and is consistent with a synchrotron origin. At a projected distance of 10 arcsec from the core, the jet is in approximate pressure balance with an external medium which is also detected through its X-ray emission and which has kT \approx 0.6 \pm 0.1 keV, consistent with earlier ROSAT results. The high spatial resolution and sensitivity of Chandra separates nuclear unresolved emission from the extended thermal emission of the galaxy atmosphere with higher precision than possible with previous telescopes. We measure an X-ray luminosity of 5.3 \times 10^{41} ergs s^{-1} (0.4--4.5 keV) and a power-law energy index of alpha = 0.4 \pm 0.4 for the nuclear component.

description: In autonomous driving systems, object detection plays a pivotal role by facilitating their ability to perceive the surrounding road environment effectively. Object detection’s foremost challenge pertains to its real-time operational capabilities. Achieving this necessitates reducing the detectors’ computational complexity while preserving their accuracy. Nevertheless, most of the approach in object detection involves dividing image processing over multiple heads, each tasked with detecting objects at particular scales. Even though this approach improves detection accuracy, it adds an extra computational burden. In this study, our objective is to assess the feasibility of employing a single head within the originally multi-headed architecture of the FCOS detector. In response to the challenges posed by this significant modification, we propose a set of straightforward solutions, resulting in the development of a novel Fully Convolutional One-Stage with a Single Head (FCOSH) detector. Through experiments on the BDD100K benchmark, our FCOSH detector exhibits substantial improvements in computational efficiency relative to the original FCOS while concurrently achieving a superior detection 0.5% accuracy. Specifically, FCOSH achieves an 18% reduction in inference time, a 24% reduction in required FLOPs, and a 10% decrease in the number of model parameters compared to FCOS.

description: Partition functions of two different matrix models for QCD with chemical potential are computed for an arbitrary number of quark and complex conjugate anti-quark flavors. In the large-N limit of weak nonhermiticity complete agreement is found between the two models. This supports the universality of such fermionic partition functions, that is of products of characteristic polynomials in the complex plane. In the strong nonhermiticity limit agreement is found for an equal number of quark and conjugate flavours. For a general flavor content the equality of partition functions holds only for small chemical potential. The chiral phase transition is analyzed for an arbitrary number of quarks, where the free energy presents a discontinuity of first order at a critical chemical potential. In the case of nondegenerate flavors there is first order phase transition for each separate mass scale.

description: Networks can describe the structure of a wide variety of complex systems by specifying which pairs of entities in the system are connected. While such pairwise representations are flexible, they are not necessarily appropriate when the fundamental interactions involve more than two entities at the same time. Pairwise representations nonetheless remain ubiquitous, because higher-order interactions are often not recorded explicitly in network data. Here, we introduce a Bayesian approach to reconstruct latent higher-order interactions from ordinary pairwise network data. Our method is based on the principle of parsimony and only includes higher-order structures when there is sufficient statistical evidence for them. We demonstrate its applicability to a wide range of datasets, both synthetic and empirical.

description: This letter presents an improved discussion of the data provided in a recent article on EDTA removal from aqueous solutions using elemental iron (Fe(0)) by O. Gyliene and his co-workers. It is shown that the authors have furnished a brilliant validation of the concept that dissolved contaminants are primary removed in Fe(0)/H(2)O systems by adsorption onto iron corrosion products and co-precipitation with iron corrosion products. It is reiterated that "contaminant removal" and "contaminant reduction" should not be interchanged randomly.

description: In the previous paper arXiv:2003.06470 we introduced the notion of ${\mathbb Z}_2\times{\mathbb Z}_2$-graded classical mechanics and presented a general framework to construct, in the Lagrangian setting, the worldline sigma models invariant under a ${\mathbb Z}_2\times{\mathbb Z}_2$-graded superalgebra. In this work we discuss at first the classical Hamiltonian formulation of some of these models and later present their canonical quantization. As the simplest application of the construction we recover the ${\mathbb Z}_2\times{\mathbb Z}_2$-graded quantum Hamiltonian introduced by Bruce and Duplij in arXiv:1904.06975. We prove that this is the first example of a large class of ${\mathbb Z}_2\times{\mathbb Z}_2$-graded quantum models. We derive in particular interacting multiparticle quantum Hamiltonians given by Hermitian, matrix, differential operators. The interacting terms appear as non-diagonal entries in the matrices. The construction of the Noether charges, both classical and quantum, is presented. A comprehensive discussion of the different ${\mathbb Z}_2\times{\mathbb Z}_2$-graded symmetries possessed by the quantum Hamiltonians is given.

description: The Cassini state equilibrium associated with the precession of the Moon predicts that the mantle, fluid core and solid inner core precess at different angles. We present estimates of the dissipation from viscous friction associated with the differential precession at the core-mantle boundary (CMB), $Q_{cmb}$, and at the inner core boundary (ICB), $Q_{icb}$, as a function of the evolving lunar orbit. We focus on the latter and show that, provided the inner core was larger than 100 km, $Q_{icb}$ may have been as high as $10^{10}-10^{11}$ W for most of the lunar history for a broad range of core density models. This is larger than the power required to maintain the fluid core in an adiabatic state, therefore the heat released by the differential precession at the ICB can drive a past lunar dynamo by thermal convection. This dynamo can outlive the dynamo from precession at the CMB and may have shutoff only relatively recently. Estimates of the magnetic field strength at the lunar surface are of the order of a few $\mu$T, compatible with the lunar paleomagnetic intensities recorded after 3 Ga. We further show that it is possible that a transition of the Cassini state associated with the inner core may have occurred as a result of the evolution of the lunar orbit. The heat flux associated with $Q_{icb}$ can be of the order of a few mW m$^{-2}$, which should slow down inner core growth and be included in thermal evolution models of the lunar core.

description: Accurate predictions of interatomic energies and forces are essential for high quality molecular dynamic simulations (MD). Machine learning algorithms can be used to overcome limitations of classical MD by predicting ab initio quality energies and forces. SE(3)-equivariant neural network allow reasoning over spatial relationships and exploiting the rotational and translational symmetries. One such algorithm is the SE(3)-Transformer, which we adapt for the ANI-1x dataset. Our early experimental results indicate through ablation studies that deeper networks - with additional SE(3)-Transformer layers - could reach necessary accuracies to allow effective integration with MD. However, faster implementations of the SE(3)-Transformer will be required, such as the recently published accelerated version by Milesi.

description: Einleitend werden die geographischen Bedingungen der Gebirgsmoore beschrieben (Höhenlage, Topographie, Klima, Wasserhaushalt). Es wird nachgewiesen, daß die Gefällsverhältnisse die Bodenwasserbewegung beeinflussen und damit die jeweiligen Vegetationskomplexe (Tab. 2). Ökotechnische Maßnahmen müssen bei Schonung der Vegetation nach dem Gefälle der Mooroberfläche ausgerichtet werden (Tab. 3). Für Hochmoor-Reste (-Blöcke), deren Fläche meist klein und deren Gefälle oft beträchtlich ist, ist eine Wiedervernässung zur Renaturierung nicht erfolgversprechend. Bei (industriell abgetorftem) Leegmoor kann dagegen die Mooroberfläche mittels Moor-Bagger oder Planiergerät auf Moorraupe horizontal umgestaltet oder unter Beachtung des Gefälles planiert werden.
description: Firstly the geographical conditions of raised bogs in the mountains are described (altitude, topography, climate, hydrological conditions). It is proved, that the gradient of the mire surface influences the soil water movement and thus the mire vegetation complex (tab. 2). Ecotechnical projects for mire rewetting and renaturalization must be geared to the mire surface slope (tab. 3). For a remaining block of raised bog peat in a cutting area, which has a small surface and a relatively great slope, a rewetting for renaturalization unsuccessful. In cut—over areas (Leegmoor) the surface can, with a mire excavator or mire bulldozer, be transformed horizontally or, depending on the gradient, levelled.

Here $n$ is the degree of the associated number field, $N(\mathfrak{m})$ is the norm of integral ideal $\mathfrak{m}$ and $Q_{f}$ is the analytic conductor of $f$. In the case of arbitrary weights, we show that there is an integral ideal $\mathfrak{m}$ with $N(\mathfrak{m}) \ll_ε Q_{f}^{1/2 + ε}$ such that $C_{f}(\mathfrak{m}) <0$. We also prove that when $k=(k_1,k_2,...,k_n) \in (2 \mathbb{Z})^n$, asymptotically half of the Fourier coefficients are positive while half are negative.

The Cassini State of the Moon's inner core

description: We present a model of the precession dynamics of the Moon that comprises a fluid outer core and a solid inner core. We show that three Cassini states associated with the inner core exist. The tilt angle of the inner core in each of these states is determined by the ratio between the free inner core nutation frequency ($\omega_{ficn}$) and the precession frequency $\Omega_p = 2\pi/18.6$ yr $^{-1}$. All three Cassini states are possible if $|\omega_{ficn}| > 2\pi/16.4$ yr $^{-1}$, but only one is possible otherwise. Assuming that the lowest energy state is favoured, this transition marks a discontinuity in the tilt angle of the inner core, transiting from $-33^\circ$ to $17^\circ$ as measured with respect to the mantle figure axis, where negative angles indicate a tilt towards the orbit normal. Possible Lunar interior density structures cover a range of $\omega_{ficn}$, from approximately half to twice as large as $\Omega_p$, so the precise tilt angle of the inner core remains unknown, though it is likely large because $\Omega_p$ is within the resonant band of $\omega_{ficn}$. Adopting one specific density model, we suggest an inner core tilt of approximately $-17^\circ$. Viscoelastic deformations within the inner core and melt and growth at the surface of a tilted inner core, both neglected in our model, should reduce this amplitude. If the inner core is larger than approximately 200 km, it may contribute by as much as a few thousandths of a degree on the observed mantle precession angle of $1.543^\circ$.

description: Seit den 1980er Jahren werden in Nordwestdeutschland industriell abgetorfte Hochmoorflächen als Folgenutzung für die Renaturierung hergerichtet und wiedervernässt. Bei der Mehrzahl dieser Renaturierungsflächen wurde das Ziel einer Hochmoorregeneration jedoch noch nicht erreicht. Gründe dafür sind neben instabilen hydrologischen Bedingungen und teilweise unpassendem Nährstoffniveau vor allem der Mangel an hochmoortypischen Pflanzenarten, insbesondere an Bulte bildenden Torfmoosen, deren spezifische Eigenschaften essentiell für die Regeneration von Hochmooren und deren Ökosystemfunktionen sind. Hauptursache hierfür ist das heute meist vollständige Fehlen von Spenderpopulationen im Umfeld der Abbaufläche. Ein 2015 gestartetes Forschungsprojekt der Stiftung Lebensraum Moor, des Substratherstellers Gramoflor und des Institutes für Landschaftsökologie der WWU Münster zielt darauf ab, die Ausbreitungslimitierung von Bulttorfmoosen durch aktive Ausbringung auf Renaturierungsflächen zu überwinden. Erste Ergebnisse des von der Deutschen Bundesumweltstiftung DBU geforderten Vorhabens werden Ende 2018 in Form einer Handlungsempfehlung für die Vermehrung von seltenen regionalen Bulttorfmoosen publiziert.
description: In northwestem Germany rewetting measures have been carried out since the 19805 to restore raised bogs which were strongly altered by cultivation and peat harvesting. Successful establishment of hummock peat mosses, which form the essential part of peat-forming vegetation, has rarely been observed, but is a prerequisite for the regeneration of bog-typical ecosystem functions. Most relevant constraints are unfavorable abiotic site conditions, but also dispersal limitation because of lacking viable source populations in the immediate surroundings must be considered as an important factor limiting the success of a restoration project. Here, we report on first results of a research project of Stiftung Lebensraum Moor in cooperation with the company Gramoflor and the University of Münster which aims to develop techniques for the establishment of hummock peat mosses in rewetted cut-over bogs. General recommendations on the propagation of diaspores for providing of donor material in bog restoration will be published by the end of 2018.

description: Similarly as in the whole economy, the modernization of agrarian sector influences on growing importance of logistics. Modern agricultural enterprises must transport and store not only huge amounts of inputs (e.g. feed, fertilizers, pesticides, energy, seeds, etc.) but also the final animal products (forage, live animals, meat etc.). This paper presents the scale of the production and transport of pig production in Poland against the background of non-agrarian products (coal, liquid fuels). Moreover, author presents the classification of the products that are part of internal and external trade and storage process in a classic pig farm.

description: Ferromagnetic properties of In1-xMnxAs thin films were investigated. Room temperature ferromagnetic order was observed in nominally single-phase films with x = 0.01-0.10. Magnetization measurements indicated that these In1-xMnxAs samples had a Curie temperature of 333 K. The Curie temperature was independent of Mn concentration. The temperature dependent magnetization along with the magnitude of the saturation magnetization and microstructural data indicate that the source of the high-temperature ferromagnetism in single-phase films is not attributable to MnAs nanoprecipitates. The high transition temperature is attributed to the presence of near neighbor Mn pairs.

description: The level of crop insurance is very low in Poland, in 2013 it was only 3.4 million hectares. The influence of the characteristics of the farm and of the farmer on decision of crop insuring, with particular emphasis on the history of crop insurance in the farm was investigated. For that purpose the multiple logistic regression model with a binary dependent variable indicating purchasing crop insurance by a farmer in 2014 was applied. The analysis confirmed the dominant influence of farmer’s experience in the insurance of crops in previous years.
From Simulation to Real World Maneuver Execution using Deep Reinforcement Learning

description: Deep Reinforcement Learning has proved to be able to solve many control tasks in different fields, but the behavior of these systems is not always as expected when deployed in real-world scenarios. This is mainly due to the lack of domain adaptation between simulated and real-world data together with the absence of distinction between train and test datasets. In this work, we investigate these problems in the autonomous driving field, especially for a maneuver planning module for roundabout insertions. In particular, we present a system based on multiple environments in which agents are trained simultaneously, evaluating the behavior of the model in different scenarios. Finally, we analyze techniques aimed at reducing the gap between simulated and real-world data showing that this increased the generalization capabilities of the system both on unseen and real-world scenarios.

description: We study the annealed complexity of the m-vector spin glasses in the Sherrington-Kirkpatrick limit. The eigenvalue spectrum of the Hessian matrix of the Thouless-Anderson-Palmer (TAP) free energy is found to consist of a continuous band of positive eigenvalues in addition to an isolated eigenvalue and (m-1) null eigenvalues due to rotational invariance. Rather surprisingly, the band does not extend to zero at any finite temperature. The isolated eigenvalue becomes zero in the thermodynamic limit, as in the Ising case (m=1), indicating that the same supersymmetry breaking recently found in Ising spin glasses occurs in vector spin glasses.

description: This paper identifies and examines the labor resources potential of chosen branches’ enterprises in Poland regarding voivodeships. An author made an attempt to point the areas where there is an opportunity to cooperate among voivodeships basing upon chosen bio-economy branches and moreover implementing the institutional support forms in this kind of activity (clusters, technological parks). An analysis concerned (according to Polish Activity Classification 2007): section A, section C – parts; 10, 13, 16 and 17 and also section E – part 38. The survey showed that Wielkopolska region(Great Poland) was characterized by above the average potential of staff employed in the greatest number of branches connected with bio-economy in relation to national average and also regions: Lubuskie, Łódzkie, Podlaskie. In the paper one pointed the groups of regions characterizing with above the average labor resources potential thus making possible to stimulate institutional cooperation among voivodeships of one and many-sectors character.

description: Abstract: The effects of different grassland management on vegetation pattern and yield potential were investigated in a long-term study on a low peat site typical for the county of Mecklenburg (Northeast-Germany). For this purpose we varied nutrient supply and the utilisation regime (cutting and grazing). Recordings of weathering data and soil water table were additional used to explain water-supply effects on grassland yields. Utilisation and K-supply were identified as the strongest predictors of vegetation patterns, whereas above ground biomass depends mainly from water supply during mid and late summer despite of significant management effects. We concluded that distinguishing between combined effects of vegetation utilisation and site condition water supply had necessarily to taken into account to got reliable information about grassland yield on drained low peat soils.
description: Zusammenfassung: In einer langjährigen Studie auf einem für Mecklenburg typischen Niedermoorstandort sind die Auswirkungen verschiedener Bewirtschaftungen auf den Pflanzenbestand und dessen Ertragsfähigkeit untersucht worden. Variiert wurden die Nährstoffversorgung und die Nutzung. Die Aufzeichnung von Witterung und Grundwasserflurabständen dienten der Abschätzung der Einflüsse des Wasserdargebotes auf den Ertrag. Der markanteste Einfluss auf die botanische Zusammensetzung des Grünlandes ging von der Nutzungsart und der Kalium-Düngung aus. Der Ertrag (bei Schnitt ohne Düngung 69 dt TM ha-1, mit NPK-Düngung 100 dt TM ha-1 und bei Weide ohne Düngung 59 dt TM ha-1, mit NPK-Düngung 74 dt TM ha-1) wurde hingegen ungeachtet signifikanter Bewirtschaftungseffekte am stärksten vom Wasserdargebot während der Sommermonate beeinflusst. Es wird gefolgert, dass für die Beurteilung der Ertragsfähigkeit von dränierten Niedermoorstandorten sowohl Nutzung als auch Witterung zu berücksichtigen sind, um zu realitätsnahen Richtwerten zu gelangen.

description: We present L'and M' photometry, obtained at UKIRT using the Mauna Kea Observatories Near-IR filter set, for 46 and 31 standard stars, respectively. The L' standards include 25 from the UKIRT in-house "Bright Standards" with magnitudes deriving from Elias et al. (1982) and observations at the IRTF in the early 1980s, and 21 fainter stars. The M' magnitudes derive from the results of Sinton & Tittemore (1984). We estimate the average external error to be 0.015 mag for the bright L' standards and 0.025 mag for the fainter L' standards, and 0.026 mag for the M' standards. The new results provide a network of homogeneously observed standards, and establish reference stars for the MKO system, in these bands. They also extend the available standards to magnitudes which should be faint enough to be accessible for observations with modern detectors on large and very large telescopes.

description: We show that the number of $t$-ary trees with path length equal to $p$ is $\exp(h(t^{-1})t\log t \frac{p}{\log p}(1+o(1)))$, where $\entropy(x){=}{-}x\log x {-}(1{-}x)\log (1{-}x)$ is the binary entropy function. Besides its intrinsic combinatorial interest, the question recently arose in the context of information theory, where the number of $t$-ary trees with path length $p$ estimates the number of universal types, or, equivalently, the number of different possible Lempel-Ziv'78 dictionaries for sequences of length $p$ over an alphabet of size $t$.

description: Food subjected to heat treatment requires a rational selection of the type of treatment and the time and manner of its conduct. The aim of the study was to compare ways of cooking in terms of palatability, productivity, mineral content and the electricity consumption for example buckwheat groats cooked in a measured amount of water and in perforated bag in excess of water. It was found that more rational way of preparing buckwheat groats not affecting on the palatability is cooking in a measured amount of water in a ratio of 2/1 due to the greater of 25% of the behavior of minerals, increased by almost 10% content of dry matter, and more than twice as less energy consumption.
