The ideal soil pH is slightly acidic, between 6.0 and 7.0. When the soil pH drops below 6.0 (becomes more acidic), certain nutrients needed for proper grass growth, such as nitrogen, phosphorus, potassium, and calcium, become unavailable to certain nutrients for proper growth and other plants. | eng_Latn | 3,784 |
what is in dolomite lime | Dolomitic limestone is a type of rock that includes up to 50% dolomite. Normal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions â this process is called dolomitization.ormal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions â this process is called dolomitization. | Dolomite, also known as dolostone and dolomite rock, is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater.olomite is a word that is used by geologists in two different ways: 1) as the name of the mineral dolomite; and, 2) as the name of a rock known as dolomite, dolostone or dolomite rock. This page is about dolomite rock. | eng_Latn | 3,785 |
minerals are comprised of one or more | Rocks-Mixtures of Minerals. Mixtures or aggregates of minerals are called rocks. There are three basic kinds of rocks, each type is determined by the process by which the rock forms. Igneous Rocks-form by solidification and crystallization from liquid rock, called magma. | Each rock is made up of one or more different minerals. For example, granite. might be composed of the minerals quartz, orthoclase feldspar, mica, and hornblende. Limestone is an example of a rock that consists of only one kind of mineral: calcite. Although there are 2000 or more kinds of minerals in the earth, only about a dozen. | eng_Latn | 3,786 |
what is active lime | Agricultural lime, also called aglime, Biolime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate.he primary reason to apply agricultural lime is to correct the high levels of acidity in the soil. Acid soils reduce plant growth by inhibiting the intake of major plant nutrients (nitrogen, phosphorus and potassium). Some plants, particularly legumes, will not grow in highly acidic soils. | Lime sulfur. In horticulture, lime sulfur (British spelling lime sulphur) is a mixture of calcium polysulfides formed by reacting calcium hydroxide with sulfur, used in pest control. It can be prepared by boiling calcium hydroxide and sulfur together with a small amount of surfactant. | eng_Latn | 3,787 |
what are some physical and chemical properties of magnesium and calcium | Chemical and Physical Properties of Magnesium.

Fibronectin and C1q frequently co-precipitated in cryoglobulins from patients with SLE. As a portion of the C1q molecule is similar to collagen to which fibronectin has a high affinity, we studied whether fibronectin specifically bound to C1q. Fibronectin was found to bind to both native and heat-inactivated C1q. The binding was enhanced by Ca++ and low ionic strength. We have also demonstrated that fibronectin is capable of binding to C1q fixed to immune complexes. The interaction between fibronectin and C1q may play a role in cryoglobulin formation and in clearance of immune complexes by reticuloendothelial system. | Plasma fibronectin (FN) was measured in 17 patients with essential mixed cryoglobulinaemia (EMC) and in 17 normal subjects by single radial immunodiffusion (RID) and enzyme-linked immunosorbent assay (ELISA). In 9 patients the presence of FN in the cryoprecipitates was also assessed by immunoblotting. In the EMC group, plasma FN levels were significantly lower than in control subjects, using both methods, and FN was constantly demonstrated in EMC cryoprecipitates. Capillaroscopic observation of the capillary bed in skin and bulbar conjunctiva, performed in all cases, showed severe alterations of microcirculation in EMC patients. A negative correlation between plasma FN and capillaroscopic abnormalities of skin capillaries was observed. These data support the hypothesis that plasma fibronectin plays a role in the pathogenesis of systemic vasculitis in EMC. | Perfect Quantum Cloning Machines (QCM) would allow to use quantum nonlocality for arbitrary fast signaling. However perfect QCM cannot exist. We derive a bound on the fidelity of QCM compatible with the no-signaling constraint. This bound equals the fidelity of the Bu\v{z}ek-Hillery QCM. | eng_Latn | 3,792 |
Effect of cascaded arrayed-waveguide grating devices with 100GHz and 50GHz channel spacings in a 10Gb/s NRZ loop system | Measured and simulated power penalties were compared for 10Gbit/s NRZ loop experiments for cascaded AWG filters with 50GHz and 100GHz channel spacings. The results show that spectral flatness of cascaded filters can strongly influence the performance of high-speed systems with small channel spacing. | We consider an approach to fault tolerant quantum computing based on a simple error detecting code operating as the substrate for a conventional surface code. We develop a customised decoder to process the information about the likely location of errors, obtained from the error detect stage, with an advanced variant of the minimum weight perfect matching algorithm. A threshold gate-level error rate of 1.42% is found for the concatenated code given highly asymmetric noise. This is superior to the standard surface code and remains so as we introduce a significant component of depolarising noise; specifically, until the latter is 70% the strength of the former. Moreover, given the asymmetric noise case, the threshold rises to 6.24% if we additionally assume that local operations have 20 times higher fidelity than long range gates. Thus for systems that are both modular and prone to asymmetric noise our code structure can be very advantageous. | eng_Latn | 3,793 |

Photonic crystal waveguides support chiral-point polarisation singularities which give rise to local chirality even in the absence of a global chiral symmetry. Placing a quantum dot at such a C-point gives rise to a uni-directional emission dependent on the electron spin - ideal for applications in quantum information as it entangles the spin direction of electrons on the quantum dot (static qubits) to the path in the waveguide (flying qubits). Here we discuss the optimisation of this chiral light-matter interaction using slow-light waveguides, and show designs with 8.6 times enhancement of the local density of optical states at a C-point. | Dynamic processes allow controlling light through a fast modification of the optical properties of the confining structure while the light is present in it. Here, we demonstrate the on-chip dynamic frequency conversion of a light signal by performing this modification through a short optical switching pulse co-propagating on-chip with the signal. A frequency-dependent propagation velocity allows the switching pulse to overtake a co-propagating signal pulse running ahead while on its way driving the dynamic process. We show a dynamic frequency shift of up to 70 GHz with a conversion efficiency of up to 25%. | Perfect Quantum Cloning Machines (QCM) would allow to use quantum nonlocality for arbitrary fast signaling. However perfect QCM cannot exist. We derive a bound on the fidelity of QCM compatible with the no-signaling constraint. This bound equals the fidelity of the Bu\v{z}ek-Hillery QCM. | eng_Latn | 3,795 |
Universal feedback control of two-qubit entanglement | We consider two-qubit undergoing local dissipation and subject to local driving. We then determine the optimal Markovian feedback action to preserve initial entanglement as well as to create stationary entanglement with the help of an XY interaction Hamiltonian. Such feedback actions are worked out in a way not depending on the initial two-qubit state, whence called universal. | Abstract This paper is concerned with the problem of distributed event-triggered H ∞ filtering over sensor networks for a class of discrete-time nonlinear system modeled by a set of linear Takagi–Sugeno(T–S) fuzzy models. In the filtering network, every individual filter receives the measurement information from the nonlinear plant, meanwhile, each filter can exchange the information with the other filters. Event-triggered communication scheme is applied to determine whether or not the current instant information should be transmitted to the quantizer. Distributed fuzzy filters are designed to guarantee the H ∞ disturbance attenuation level for the error estimation of the filtering network. Finally, a simulation example is provided to illustrate the effectiveness of the proposed filter design approach. | eng_Latn | 3,796 |
