To seek for the best at the combination of variety and the nitrogen level of correspond chemical components of tobacco leaf and improve quality.We studied on influence of chemical components and derivatives in different variety under different fertilization rates.The results indicated the amounts of ...
Physical chemistrystudies the rates of chemical reactions, how molecules interact with radiation like in nuclear chemistry, and calculations involving structures and properties. Spectroscopy is a subcategory of physical chemistry that focuses on how matter absorbs and scatters electromagnetic energy. ...
Manganese-oxides are one of the most important minerals in soil due to their widespread distribution and high reactivity. Despite their invaluable role in ... MHH Fischel,JS Fischel,BJ Lafferty,... - 《Geochemical Transactions》 被引量: 8发表: 2015年 Heterogeneous Reaction of SO2 on Manganese...
Additionally, Mg-based corrosion products maintain pH of local electrolyte at approximately 10.2, preventing the transformation of basic Zn salts (simonkolleite and hydrozincite) into more porous Zn oxides and carbonates [18,19]. However, corrosion products of Zn-Al-Mg and their respective ...
koraiensis trees often have relatively slow growth and seed production rates. As an attempt to provide abundant and punctual supplies, technical innovation has been applied to develop their performance. Mutke et al. (2012) reported that the practical grafting from selected highly productive trees ...
Zr-2 and SiC have the characteristics that cracks do not spread through the cladding during a power ramp, their irradiation stability, the stress level low10,11,12, the ability to maintain their mechanical properties and chemical inactivity at high temperatures13, and exceptional resistance to ...
Element addition also brings to a wide range of measured corrosion rates, spanning from 0.188 ± 0.017 mm/year for Zn-3Ag-0.5Mg [34] to 0.044 ± 0.008 mm/year for Zn-5Cu [33]. These alloys, tested in commonly used physiological media, showed intergranular and micro-galvanic corrosion ...
Plants constantly monitor chemical cues in order to distinguish between essential ones predicting competitive neighbors and those cues that are not important for their own fitness [13,14]. In response to essential chemical cues, a single plant can exhibit a multitude of adaptation responses, ...
Each drag model was validated for different data sets and their validity is only confirmed for the corresponding conditions. Table 3 shows a summary of the conditions where the different drag models can be used. Table 3. Information about the drag models available in Barracuda® 17.1. 3.4. ...
However, this fixation is largely reversible over time, as plant roots can take up P accumulated in soil through the application of fertilizers and organic sources over many years [1]. By differentiating between fertilizer application rates, one can determine their suitability for crop uptake. The...
