Resumen

The processing of materials by cutting with abrasive tool is carried out by means of thousands of grains bonded together as a single whole. The quality of abrasive tool is defined by cutting properties of abrasive grains and depends on features of spreading of temperature field in time and in abrasive grain volume. Grains are exposed to heating and cooling during work. It leads to undesired effects such as decrease of durability of grain retention in the binder, hardness, intensification of diffusion and oxidation processes between the binder and grain, the occurrence of considerable temperatu

Resumen

Thousand-grain weight is a key indicator of crop yield and an important parameter for evaluating cultivation measures. Existing methods based on image analysis are convenient but lack a counting algorithm that is suitable for multiple types of grains. This research develops an application program based on an Android device to quickly calculate the number of grains. We explore the short axis measurement method of the grains with morphological thought, and determine the relationship between the general corrosion threshold and the short axis. To solve the problem of calculating the number of grai

Resumen

The microstructures and mechanical properties of cold upsetting magnesium alloys were investigated upon anneal under different conditions. The results show that a large amount of twins were observed in the original grains of cold upsetting AZ31 magnesium alloys. The twins disappeared gradually and recrystal grains formed after anneal. The volume fraction of the recrystal grains increases as the strain of samples rises. Recrystal grain size grows large with the elevated annealing temperature. Recrystal grain size reduces at first and then grows as the annealing time is prolonged. In addition, c

Resumen

Favorable weather and climate conditions for growing grain are also favorable for the livelihoods and reproduction of pests of grain stocks, and especially for wheat bug (Eurygaster integriceps Put.). Grain damaged by this pest loses its genetically incorporated properties, negative changes occur in the quantity and quality of gluten. Due to the ingestion of bug’s saliva with its special enzymes into the grain, the baking properties of the flour from such grain deteriorate – the dough becomes liquid, sticky, it loses elasticity. Thus, the issue of further effective use of grain damaged by the

Efficiency of the polishing process is determined by the properties of abrasive grains, including its form parameter and orientation in the body of the grinding tool. It is possible to improve the operational characterizations of the grinding instruments, in particular – cutting discs, by ordering of the grain geometry, selection of the rational form and orientation of abrasive grains for specific processing conditions and parameters of the power load.

Commonly used as a finishing operation, lapping has been used for achieving ultra-high finishes and close tolerances between mating pieces. Its carried out by applying loose abrasive grains between work and lap surfaces, and causing a relative motion between them resulting in a finish of multi-directional lay. The grains activity (sliding and rolling) in the working gap causes not only the material removal but also the temperature rise of lap plate.

The epidemiological data that directly examine whole grain v. refined grain intake in relation to weight gain are sparse.

In both clinical trials and observational studies the intake of whole-grain foods was inversely associated with plasma biomarkers of obesity, including insulin, C-peptide and leptin concentrations.

Resumen

As a common solid waste in geotechnical engineering, rock granular material should be properly treated and recycled. Rock granular material often coexists with water when it is used as the filling material in geotechnical engineering. Water flowing in rock granular materials is a complex progress with the mechanical–hydrological–chemical (MHC) coupling effect, i.e. the water scours in the gaps and spaces in the rock granular material structure, produces chemical reactions with rock grains, rock grains squeeze each other under the water pressure and compression leading to re-breakage and produc

Resumen

The precipitates and precipitation kinetics of super austenitic stainless steel with high Mo and N (HHSASS) were investigated by optical microscope (OM), scanning electron microscope (SEM) and quantitative metallography method. The results show that the TTP curves are C-shaped, the “nose” temperatures of precipitation are found to be 1000°C with the incubation periods of 120s and 600s, respectively. At 1000°C, some precipitates form as ellipsoidal-shaped and connect along the grain boundaries first. Then a few precipitates start forming as needle-shaped within austenite grains. Until aging for

Resumen

Purpose The health benefits of whole grains are well established, yet intake remains below recommendations. Knowledge and familiarity with whole grains may increase short-term intake, but sensory properties can limit consumption. These factors usually are researched separately, thus, this study aims to explore the relationships among sensory liking, knowledge, attitudes and intake. Design/methodology/approach This cross-sectional study had 69 college students participate in four tasks: sensory liking of whole vs refined grain bread, rice, pasta and tortillas; bitter taster status; knowledge an

The selection of pairs for hybridization requires knowledge about the correlation of the most important quantitative traits that affect grain yield of maize hybrids. The current study was carried out in the Agricultural Research Center “Donskoy” located in the south of the Rostov region with unstable moisture. The years of study (2018–2020) were arid (HThC 0.32–0.89). The purpose of the current study was to evaluate the correlation between quantitative traits and their influence on grain yield of maize hybrids under arid conditions.

Resumen

Rock is an aggregate of mineral grains, and the grain shape has an obvious influence on rock mechanical behaviors. Current research on grain shape mostly focuses on loose granular materials and lacks standardized quantitative methods. Based on the CLUMP method in the two-dimensional particle flow code (PFC2D), three different grain groups were generated: strip, triangle, and square. Flatness and roughness were adopted to describe the overall contour and the surface morphology of the mineral grains, respectively. Simulated results showed that the grain shape significantly affected rock porosity

Resumen

To understand and manipulate the interactions between plants and microorganisms, sterile seeds are a necessity. The seed microbiome (inside and surface microorganisms) is unknown for most plant species and seed-borne microorganisms can persist and transfer to the seedling and rhizosphere, thereby obscuring the effects that purposely introduced microorganisms have on plants. This necessitates that these unidentified, seed-borne microorganisms are removed before seeds are used for studies on plant–microbiome interactions. Unfortunately, there is no single, standardized protocol for seed steriliz

The form of grinding grains is an important parameter which as show researches, has a great impact on efficiency of use of grinding tools. Generally the methods used for an assessment of a form of grinding grains can be divided into two groups – qualitative and quantitative. The principle of an assessment of a form of grain on qualitative methods is based on grain reference on some signs in the relevant group of forms. All existing ways of a quantitative assessment of a form of grain are based on research of a horizontal projection of grain. However application of horizontal projection results

Coloured (black, purple, blue, red, etc.) cereal grains, rich in anthocyanins, have recently gained a lot of attention in the food industry. Anthocyanins are water-soluble flavonoids, and are responsible for red, violet, and blue colours in fruits, vegetables, and grains. Anthocyanins have demonstrated antioxidant potential in both in vitro and in vivo studies, and the consumption of foods high in anthocyanins has been linked to lower risks of chronic diseases. As such, whole grain functional foods made with coloured grains are promising new products. This paper will review the characteristics
