Abstract:

In Kazakhstan, the basis of the country's food security is livestock products. Increasing the production of livestock products is impossible without creating a strong feed base, high-quality preparation of feed, rational use and reduction of feed losses. Preparation of coarse stem feed for feeding requires grinding with feed grinding and mixing machines to obtain balanced feed mixtures. The grinding process is complicated by the fact that, along with coarse stem feed, foreign solid impurities enter, which damage the cutting organs of machines and cause a long shutdown of the entire feed prepar

Abstract:

Seaweed foreign object detection has become crucial for food consumption and industrial use. This process not only can prevent potential health issues, but also maintain the overall marketability of seaweed production in the food industry. Traditional methods of inspecting seaweed foreign objects heavily rely on human judgment, which deals with large volumes with diverse impurities and can be inconsistent and inefficient. An automation system for real-time seaweed foreign object detection in the inspection process should be adopted. However, automated seaweed foreign object detection has sever

Abstract:

With increasing population levels and rapidly growing industries worldwide, the purification of water contaminated with different impurities is one of the biggest challenges we face in recent times. Photocatalysis holds great potential as an efficient mineralization process to remove the foreign matter present in wastewater. Rapid advancement in innovative materials development has made photocatalysis the frontrunner among different water treatment methods. Our main priority lies in different strategic approaches to improve photocatalytic performance. This review discusses the recent breakthro

Abstract:

One of the debatable problems of modem combat injury surgery is surgical tactics against foreign bodies of firearms genesis. Most often it is metal foreign bodies with a significant content of iron. To develop a sound treatment tactic, a more in-depth study of the interaction of foreign bodies with soft tissues at the tissue, cellular, subcellular level is needed. One such method may be X-ray diffraction analysis. The aim of the work is to modernize the X-ray diffraction method to enable structural analysis of nano impurities in biological tissues, to obtain and generalize data on the degree o

Freekeh is produced from roasted, immature wheat grains. It is very popular in Middle Eastern and North African nations. This study aimed to evaluate the occurrence of different types of mycotoxins, physical impurities, and microbiological contamination in local freekeh products. Lateral flow competitive immunochromatographic assay was used to evaluate the occurrence of mycotoxins. It was found that physical impurities for some tested products exceeded the permitted limit (>2% of straw and foreign grains). Moreover, our findings showed that total aerobic bacterial and fungal counts in Freek

Stoichiometric mercury-telluride (HgTe) nanocrystals, free from any foreign impurities, have been prepared by an electrochemical technique. Transmission electron microscopy and selected area diffraction studies confirm that the size of HgTe nanocrystals with cubic phase range from 4 – 7 nm and are preferentially oriented. Optical absorption studies indicate that the band gap of HgTe nanocrystals is 2.14 eV. Room temperature photoluminescence measurements show band edge and trap dominated luminescence in the visible regime. Micro-Raman scattering analysis of the HgTe nanocrystals sample reveals

Abstract:

A comprehensive model for the metastable defects in amorphous Si:H is developed by adapting a recent theory for several kinds of defects in crystalline semiconductors, particularly the DX center in AlGaAs. This new model accounts in a unified way for all of the major observations of defects induced by light, quenching, doping, or compensation; as well as for their anneal. The stretched-exponential time dependence of defect densities with light exposure or annealing, and saturation of the density are also explained. This model is based on foreign atoms rather than on breaking of Si-Si bonds, an

Recycling materials back to supply chain not only mitigates the shortage of critical materials such as the metals of Li, Ni, Co, etc, but also protects global environment. Direct recycling of lithium nickel manganese cobalt oxides (NMC) mainly relies on a relithiation process based on purified spent NMC cathode materials. How to efficiently get rid of chemically bonded surface impurities on spent NMC and obtain a clean surface is critical for relithiation. One of the unavoidable impurities is fluorine, which exists in the form of either carbon fluoride (CFx) or metal fluoride (M-F) and can be

VO 2+ and Mn 2+ show characteristic hyperfine structure but no hyperfine splitting was observed in the spectra of Cu 2+ ions. It appears that VO 2+ and Mn 2+ are situated in one kind of void situated in an ordered way. The Cu 2+ ions may be occupying both kinds of voids, distributed in an irregular fashion.

To address these challenges, researchers have explored alternative methods for cotton drying. One such approach involves the use of ceramics as a basis for effective cotton drying, which not only saves electric energy but also ensures high-quality drying. However, this method does not fully address the issue of cleaning the cotton from small impurities during the drying process. The aim is to impro
