Remove an element from the specified index

Previous scholars have executed adequate researches on material removal mechanism of SiC and Al during FAP [ 6, 7, 8 ]. Therefore, this article aims to investigate the removal patterns of SiC particles during the polishing process using molecular dynamics simulations and FAP experiments.

Rain removal from a video is a challenging problem and has been recently investigated extensively. Nevertheless, the problem of rain removal from a single image was rarely studied in the literature, where no temporal information among successive images can be exploited, making the problem very challenging. In this paper, we …

Complete and effective sulfur removal from liquid fuels is essential to meet the sulfur standard requirements. The oxidative desulfurization (ODS) process has been extensively used for the …

Water is the most necessary and significant element for all life on earth. Unfortunately, the quality of the water resources is constantly declining as a result of population development, industry, and civilization progress. Due to their extreme toxicity, heavy metals removal from water has drawn re …

Cancellation of Removal: A form of pardon that allows an immigration judge to "cancel" a finding of removability and permit a person to remain in the United States as a lawful permanent resident. There are two forms of cancellation of removal. One is available to certain lawful permanent residents who have been in the United States for at ...

The process involves separating the feedstock by fractional distillation into a lower boiling fraction which contains the more volatile sulfur-containing aromatic impurities and at least one higher boiling fraction which contains the less volatile sulfur-containing aromatic impurities. Each fraction is then separately subjected to reaction ...

Summary Ghost reflections are the main limiting factor of the resolution of marine seismic data. Several acquisition and processing techniques have been proposed to address this problem. Some of the recently introduced acquisition methods are over/under streamer, slanted streamer, geostreamer (hydrophone/geophone streamer). These methods …

Therefore, a fundamental understanding and quantitative numerical modelling of the wet removal process are critical for evaluating aerosol's climate forcing, which is the major scientific ...

One recent area of innovation to remove sulfur from upgraded crude is oxidative desulfurization, a process that can operate under mild conditions and without …

Removing sulfur (S) from natural gas and from refined petroleum products (such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils) is widely done by HSD …

Removal of nitrogen from anaerobically digested swine manure centrate was investigated in a photo-sequencing batch reactor (PSBR) with alternating light and dark periods. Microalgal photosynthesis was shown to provide enough oxygen for complete nitritation during the light period. With addition of a …

In such a process, it is proposed to selectively oxidize and remove the aromatic sulfur- and nitrogen-containing from oil using oxidizing agent and highly …

AOPs technologies are essentially a process intensification through the use of hybrid methods for wastewater treatment, which generate large amounts of hydroxyl (•OH) and sulfate (SO4·−) radicals, the ultimate oxidants for …

The current industrial method for removal of sulfur from fuels is hydrodesulfurization (HDS), which is a high temperature, high pressure catalytic process. This makes HDS a …

In a first instance to demonstrate the feasibility of using hybrid Al-Fe electrodes in the removal of As and F −, a single well was identified with concentrations of these contaminants above the current regulations, in addition to …

One of these applications makes use of the sulfate originating from seawater toilet flushing to serve as an electron carrier to realize a new sulfur-based biological nitrogen removal process for saline wastewater, namely the S ulfate reduction A utotrophic denitrification N itrification I ntegrated (SANI ®) process ( Lau et al., 2006; Wang et ...

In this study, we discuss the removal of fluoride from water through column adsorption methods using Al(OH)3@AC as a functional granular activated carbon. The height of the bed, fluoride concentration, and flow rate are the experimental factors used to obtain the breakthrough curves. As the flow rate increased, the

Thiosulfate, as an intermediate of biological sulfate/sulfite reduction, can significantly improve nitrogen removal potential in a biological sulfur cycle-based process, namely the Sulfate reduction-Autotrophic denitrification-Nitrification Integrated (SANI(®)) process. However, the related thiosulf …

The study was based on the removal of nitrate and sulfide, and aimed to nitrite accumulation. The process of autotrophic denitrification driven by sulfide as an electron donor was investigated in a sequencing batch reactor. The research showed that autotrophic denitrification successfully started on …

Some simple commands that remove post-processing when executed.

A small addition of Hf (<1025 parts per million atoms, ppma) significantly improved the B removal. It was confirmed that the use of an increased Hf addition, slower cooling rate, and Al-rich Al–Si melt as the refining solvent removed B more efficiently. B in Si could be removed as much as 98.2% with 410 ppma Hf addition when the liquidus ...

Learn the answers to all of your laser hair removal questions, including the risks and side effects, pain, how long it takes, and whether it's permanent.

Here are a number of blogs and other articles to help you better understand tattoo removal in general, the process of laser tattoo removal, expected results from Removery's tattoo removal process, and many other educational topics.

Iron, the predominant impurity in quartz ores, can be substantially removed via aqueous chemical processes using organic and inorganic acids. Quartz was highly purified by leaching with sulfuric acid (H 2 SO 4) in the presence of reducing agents (oxalic acid, citric acid, and glucose). The effects of the parameters in the leaching tests were ...
