Abstract The aim of this study was to assess the effect of the introduction of food waste sunflower husk (SH) into the diet on the change in the chemical composition of biological media (blood and saliva) against the background of control (C). The studies were carried out on young 8-month cattle; ration of C - 70% roughage, 25% - concentrated feed, 5% - premix; SH - ration C + 10% sunflower husk (shredded, 0.5–2 mm), instead of the coarse part of the ration. The selection of biosubstrates (saliva, blood) was carried out in the morning before feeding: saliva was obtained by the method of local pharmacological stimulation of salivation (2% sodium citrate solution), blood from the jugular vein into vacuum tubes with a coagulation activator. The chemical composition of biological media was carried out on an automatic biochemical analyzer CS-T240 (Dirui Industrial Co., Ltd., China) using commercial biochemical kits for veterinary medicine (DIAKON-DS, Russia; Randox Laboratories Ltd, Great Britain). The inclusion of SH in the diet contributed to an increase in serum urea by 82.4% (P ≤ 0.05), lipase enzyme by 81.5% (P ≤ 0.05), uric acid by 62.7% (P ≤ 0.05), Ca and P by 73% and 21.8% (P ≤ 0.05), while a decrease in p-Amylase by 63.6% (P ≤ 0.05) and Fe by 86.8% (P ≤ 0.05) relative to C. After SH administration an increase in urea by 73% (P ≤ 0.05), digestive enzymes - lipase by 76.4% (P ≤ 0.05), p-amylase by 61 % (P ≤ 0.05), calcium by 69.3% and iron by 45% (P ≤ 0.05) and superoxide dismutase enzyme in comparison with C was registered in saliva. The obtained data show an increase in the level of digestive enzymes and elements in blood and saliva of ruminants, which favorably contributes to the use of sunflower husk in feeding cattle. This research was performed with financial support from the RSF (# 20-16-00088).

Due to low density and good mechanical properties, aluminium alloys are widely applied in transportation industry. Moreover, they are characterized by the specific physical properties, such as high electrical conductivity. This led to application of the hypoeutectic Al-Si-Mg alloys in the power generation industry. Proper selection of the alloys chemical composition is an important stage in achievement of the demanded properties. The following paper presents results of the research on the influence of alloys chemical composition on their properties. It has been revealed that Si and Ti addition decreases electrical conductivity of the Al-Si-Mg alloys, while Na addition increases it. The mechanical properties of the investigated alloys are decreased by both silicon and iron presence. Sodium addition increases ductility of the Al-Si-Mg alloys.

The influence of post-processing conditions on the magnetic properties of amorphous and nanocrystalline microwires has been thoroughly analyzed, paying attention to the influence of magnetoelastic, induced and magnetocrystalline anisotropies on the hysteresis loops of Fe-, Ni-, and Co-rich microwires. We showed that magnetic properties of glass-coated microwires can be tuned by the selection of appropriate chemical composition and geometry in as-prepared state or further considerably modified by appropriate post-processing, which consists of either annealing or glass-coated removal. Furthermore, stress-annealing or Joule heating can further effectively modify the magnetic properties of amorphous magnetic microwires owing to induced magnetic anisotropy. Devitrification of microwires can be useful for either magnetic softening or magnetic hardening of the microwires. Depending on the chemical composition of the metallic nucleus and on structural features (grain size, precipitating phases), nanocrystalline microwires can exhibit either soft magnetic properties or semi-hard magnetic properties. We demonstrated that the microwires with coercivities from 1 A/m to 40 kA/m can be prepared.

The structural and strength analysis of the material used to construct such an important engine element as the turbine is of great significance, both at the design stage as well as during tests and expertises related to emergency situations. Bearing in mind the conditions above mentioned, the paper presents the results of research on the chemical composition, morphology and phased structure of the metallic construction material used to produce the blades of the high and low pressure turbine of the RD-33 jet engine, which is the propulsion unit of the MiG-29 aircraft. The data obtained as a result of the material tests of the blades allowed, on the basis of the analysis of chemical composition and phased structure, to determine the grade of the alloy used to construct the tested elements of the jet engine turbine. The structural stability of the material was found to be lower in comparison with engine operating conditions, which manifested itself as a clear decrease in the resistance properties of the blade material. The results obtained can be used as a basis for analyzing the life span of an object or a selection of material replacements, which enable to produce the analyzed engine element.

The relationships between the parameters of the structure of heat‑treated steels and their abrasive wear resistance are established. At all temperatures of the final tempering of hardened steel, there is a direct relationship between its structure parameters (the number of elements in a solid solution, the density of dislocations, the size of cementite particles and the intercementite distance) and wear resistance when sliding friction against loose abrasive particles. A computer program has been developed to select the chemical composition of the steel grade and methods of thermal hardening in order to ensure the required wear resistance.

The selection of native Lavandula species and their economic exploitation have increased in the last few years. Micropropagation techniques have been used as an alternative for vegetative propagation allowing the multiplication of selected genotypes and chemotypes. Our previous studies showed that the essential oils of Lavandula pedunculata have an important antifungal activity against dermatophyte strains. Therefore, a new line of investigation concerning the in vitro culture of this species is justified. In the present study we compare the morphology of the leaf trichomes and the chemical composition of their essential oils in both field-growing and in vitro propagated plants.

Rosmarinus officinalis L. presents a high genetic variability, which is reflected in the chemical composition of the different individuals, and consequently in its biological activity, including antioxidant capacity. The aim of the present research was to correlate the chemical composition of methanolic extracts of the dried leaves of eight rosemary accessions with their antioxidant activity for the selection of plants to optimize the use of rosemary. The eight samples examined, starting from a collection of more than 160 individuals selected by BOTANE Ltd, were cultivated at Illapel, north central Chile, using the same cultivation techniques. The free radical-scavenging capacity was tested by the ability of extracts to bleach the stable 1,1-diphenyl-2-picryl-hydrazyl radical (DPPH) and to inhibit superoxide anion (O2-) and hydroxyl radical (.OH) production. The metal chelating activity was estimated by the ferrozine assay. All extracts (1–8) contained high concentrations of carnosic acid, and to a minor extent rosmarinic acid, and exhibited antioxidant activity. However, extracts 7 and 8, containing 31.7 and 26.1% of carnosic acid, respectively, have shown a higher biological effect, confirming that the antioxidant activity of R. officinalis leaves is primarily related to this phenolic diterpene and suggesting that the measure of antioxidant activity could be considered a good method in the selection of this plant for its optimization. Interestingly, our experimental evidence also suggests that air pollution negatively influences the carnosic acid content. In fact, samples 3 and 4, with a low carnosic acid content, originated from a highly polluted metropolitan area of Santiago city.

Alpacas, like other camelids, are induced ovulators. A study was designed to determine the effect of the ovulation-inducing stimulus on the biochemical composition of follicular fluid. Adult female alpacas (n = 18) were examined daily for 3 days by transrectal ultrasonography using a 5-MHz linear-array transducer (Aloka SSD-500, Tokyo, Japan). When the largest growing ovarian follicle was ≥7 mm, alpacas were given 1.0 mL of seminal plasma intramuscularly (SP, n = 9) or 40 µg of busereline acetate intramuscularly (GnRH, n = 9). A transvaginal transducer with an attached needle guide (Aloka UST-945BP-5) was used for collection of follicular fluid 22 h post-induction. Follicular contents were then centrifuged at 800 × g for 20 min to separate the fluid from the cells. The follicular fluid was collected and stored at –20°C until analysis with a semi-automatic biochemical analyzer (SINOWA, China). The results were glucose 49.17 and 47.95 (mg/dL; P > 0.05), total protein 1.85 and 1.15 (g/dL; P < 0.05), albumin 1.11 and 1.13 (g/dL; P > 0.05), triglycerides 3.94 and 3.16 (mg/dL; P > 0.05), cholesterol 39.01 and 42.5 (mg/dL; P > 0.05), phosphatase 32.68 and 21.36 (IU/L; P < 0.05), alanine aminotransferase 3.66 and 5.07 (IU/L; P > 0.05), and lactate dehydrogenase 42.17 and 27.27 (IU/L; P > 0.05) for SP or GnRH treatments, respectively. Results suggest the need to continue research to explain the effect of possible differences in total protein, cholesterol, and phosphatase on oocyte-expressed genes and follicular development.
