Abstract: It is shown that the most important electrical design criteria for long (i.e., stability limited) high voltage overhead transmission lines operating at a given voltage are all related to the …
Spatial distribution characteristics of soil chromium content Horizontal distribution characteristics of Cr and Cr(VI) in each vertical layer A spatial distribution map was created using the interpolation approach based on the depth data of soil core samples per meter to show the distribution rules of Cr and Cr(VI) in each depth horizontal direction.
As regional studies of the spatial distribution of grazing intensity do not exist, we compared our results to the global product by Fetzel et al., cut to the area of Kazakhstan . While the resolution of the maps is not comparable, the suitability algorithm employed by Fetzel et al. [ 68 ] resulted in a similar relative distribution of grazing intensity.
Den elektrokemiska spänningsserien är den skala som visar i vilken ordning metallerna kommer när det gäller ädla och oädla metaller.Man kan kalla den en "oxidationsskala" eftersom man med hjälp av den elektrokemiska spänningsserien kan avläsa vilken av två metaller som kommer att oxidera/reducera i händelse av en redoxreaktion som är oädla bildar gärna joner och de …
Alla elektrokemiska celler består av två elektroder som sänkts ner i en elektrolyt, till exempel en jonlösning. Detta är ett slutet system där elektroner överförs i kemiska reaktioner. Det finns två typer av elektrokemiska celler, galvaniska celler som alstrar elektrisk ström och elektrolysceller som förbrukar elektrisk ström. Ett vanligt AA-batteri är ett exempel på en galvanisk ...
Here, we develop an approach to visualize the nucleation centres controlling polarization switching processes with nanometre resolution, determine their spatial and energy …
The spatial distributions of antibonding π * and σ * states in epitaxial graphene multilayers are mapped using electron energy-loss spectroscopy in a scanning transmission electron microscope. Inelastic channeling simulations validate the interpretation of the spatially …
This paper deals with the spatial distribution of the energy dissipated within the cascades at the end of the slowing-down process This distribution is of central interest in the theory o

7. Vilket av följande grundämnen är det starkaste reduktionsmedlet; H, Al, Cu, Zn? Svar: Al eftersom Al är längst till vänster i den elektrokemiska spänningsserien. Al oxideras alltså lättast av dessa ämnen och kan därmed också lättast reducera andra ämnen (eftersom Al avger elektroner till andra ämnen så att dom reduceras). 8.
To better understand the effects of spatially non-uniform Sc concentrations, the electronic and ferroelectric (FE) properties of AlScN as a function of Sc distribution are studied using density functional theory (DFT).
New energy vehicles (NEVs) have been recognized as a sustainable eco-innovation to address China''s energy and environment problems. As a strategically emerging industry, China''s NEV manufacturing industry has been prioritized by governments and manufacturers, significantly impacting its spatial distribution pattern and stimulating the goals of …
Oosterho I counterparts. The analysis of their spatial distribution shows a systematic di erence between foreground, central and background regions in the occurrence of the Oosterho II group. The di erence between the OoI and II groups is also seen in their distance distributions with respect to the Galactic bar, but neither group is associated
An important explanation of the spatial distribution of the MSMEs are localization economies that arise from a spatial clustering of economic activities in either the same sector or related industries. As shown by [6,7], localization economies, including agglomeration and urbanization effects, may be decisive in explaining the emerging spatial ...
Traditional villages carry the essence of traditional culture, which is necessary for rural revitalisation. However, continuous urban expansion has resulted in the rapid decline and even disappearance of these villages in recent decades. It is necessary to analyse the spatial pattern and influencing factors for the protection and development of traditional villages. …
The spatial distribution and content of eight heavy metals in topsoil (0–20 cm) and subsoil (150–200 cm) was analyzed utilizing grid survey data. The ecological risks of heavy metals in the topsoil were assessed using the subsoil content as reference background values. The sources of heavy metals in the topsoil were further analyzed.
The spatial distribution of potential forestation land with a resolution of 30 m obtained in this study can provide an important reference for the nationwide forest planting plan for carbon sequestration. Based on 30 m resolution remote-sensing classified land use/land cover data from GLC_FCS30 and GlobeLand30 in 2020, and combined with ...
Soil organic matter (SOM) in cultivated land is vital for land quality and food security. This study examines SOM distribution and influencing factors in northeastern China, providing insights for sustainable agriculture. Utilizing 10 m resolution SOM data, the analysis covers regions including the Greater and Lesser Khingan Mountains, Liaohe Plain, Sanjiang …
The recent emergence of distributed generation, smart meters, and electric vehicles means that much attention is now being given to network modelling and analysis at the distribution, rather than transmission, level. Many optimisation studies, both regarding technical and economic questions, aim to satisfy the constraints posed by grid infrastructure. We explore …
The spatial distribution of the urban agglomeration population has changed increasingly in rapid urbanization. It affects the urban economy, environment, transportation, and so on. Therefore, it ...
In fluids, the distributions of particles are correlated due to their interactions. That is, the spatial probability distributions of particles depend on where other particles prefer …
Electrolytic plasma-assisted chemical etching (EPACE) based on electrochemical anodic oxidation and high-activity electrolytic plasma etching is an ideal …
Oxidations-reduktion eller redoxreaktioner äger rum i elektrokemiska celler. Det finns två typer av elektrokemiska celler. Spontana reaktioner inträffar i galvaniska (voltaiska) celler; icke-spontana reaktioner inträffar i elektrolytiska celler. Båda typerna av celler innehåller elektroder där oxidations- och reduktionsreaktionerna sker.
By combining state-of-the-art DPC-STEM experiments with advanced electron scattering simulations we are able to map the spatial distribution of the electron cloud within individual atomic...
The spatial distribution of ecological risks (Fig. S1) indicated that higher risks were located in the area surrounding the MMR, the northern channel of the YRE and the area to the south of the YRE region.
