Opis:
Germination can be used to enhance nutritional value and health functions of edible seeds. Sprouts are considered healthier than non-germinated seeds because they are richer in the basic nutritional components (protein, amino acid, carbohydrates, and minerals) and also contain more bioactive components. The present study is the first to dynamically analyze the germination properties regarding morphological characteristics, nutrient compounds, bioactive components and antioxidant activities of Firmiana platanifolia (F. platanifolia) seeds. The results showed that the appearance, color and morphology of F. platanifolia seeds and sprouts at different germination times showed considerable differences. With the increasing germination time, the moisture content, sucrose, fructose, total flavonoid content and DPPH significantly increased, and reached the peak at 8 d of germination, almost 2.38, 5.76, 4.02, 7.97 and 8.91 times higher than those of at 0 d, respectively. The soluble protein, total phenolic, ABTS and ferric reducing antioxidant power (FRAP) increased first and then decreased as the germination time increased, and were overall higher than those of at the initial concentration. However, total starch content and mineral elements decreased as germination progressed. Additionally, the total flavonoid content showed a strongly positive correlation with DPPH (p<0.01), whereas the total phenolic and total flavonoid content showed a similar, significant and positive correlation with ABTS and ferrous ion chelating activity (FICA, p<0.05). Therefore, seed germination significantly increased phytochemical contents and antioxidant activity. The current research results will help to reveal the dynamic changes in nutrient content and antioxidant activity of F. platanifolia seeds during the germination process, and provide reference data for further studying the development and utilization of germinated seeds.

Opis:
The study assessed children’s ability to develop narratives and express ideas. It comprised 120 children (5-10 years), and differences in relation to age, sex, and economic area were measured. To this end, we compared four schools in 2 economic areas (poor and average). We used 2 picture and 2 story re-telling tasks designed to elicit narrations reflecting the generation of ideas in response to visual and auditory stimuli. Significant differences for age and sex but not economic areas were found. Suggestions are made for balancing brain activity and developing more creative approaches in teaching and assessment.

Opis:
Marine accidents are caused by complex and diverse causes. Therefore, it is necessary to analyse accidents from the perspective of the whole system rather than the existing analysis models that focus on cause-effect. The STAMP analysis is a constraint-based model that focuses on improper management or enforcement of safety-related constraints in system operation. Thus, as a case study of the application of the STAMP technique in marine accident analysis, the Milano Bridge pier contact accident that occurred on April 6, 2020 in Busan New Port of South Korea was analysed by the STAMP technique in this study. Through this study, it was proposed to break away from the domestic accident investigation, which focused only on the punishment of the ship operator, and to suggest improvements that enable organizations related to the marine accidents to take initiative to take efforts for safety.

Opis:
Seminal plasma (SP) proteins are responsible for sperm functional quality. Developing a reliable method to determine the degree of oxidative damage of these proteins is important for establishing semen fertilizing ability. The main aim of the study was to verify the applicability of protein carbonyl derivatives measurement in the SP of canine and stallion, using a method with 2,4-dinitrophenylhydrazine (DNPH). The research material consisted of ejaculates obtained from eight English Springer Spaniels, and from seven half-blood stallions during the breeding and non-breeding season. The content of carbonyl groups in the SP was measured on the basis of the reactions with DNPH. The following reagent variants were used to dissolve protein precipitates: Variant 1 (V1) – 6M Guanidine solution and Variant 2 (V2) – 0.1M NaOH solution. It has been shown that to obtain reliable results for the measurement of protein carbonylated groups in the dog and horse SP, both 6M Guanidine and 0.1M NaOH may be used. A correlation was also found between the number of carbonyl groups and the total protein content in the canine (V1: r = -0.724; V2: r = -0.847) and stallion (V1: r = -0.336; V2: r = -0.334) SP. Additionally, the study showed a higher content (p≤0.05) of protein carbonyl groups in the stallion SP in the non-breeding season compared to the breeding season. The method based on the reaction with DNPH, due to its simplicity and cost effectiveness, appears to be suitable for large-scale application in the determination of the SP proteins oxidative damage in dog and horse semen.

Opis:
The paper presents the results of research aimed at developing assumptions for the preparation of a charge in the form of fine scrap copper alloys (chips/shells) guaranteeing effective removal of impurities and obtaining a metal bath of the required metallurgical quality. The tests were conducted for tin-zinc-lead bronze of the CC499K grade. As part of the work, the characteristics of this type of waste available on the market were made in terms of quality and the possibility of their use for the production of both alloys and finished products, taking into account the elimination of harmful impurities that may ultimately affect the production process adversely. The subject of the work was the selection of appropriate waste cleaning methods in the form of an oily shell in the CC499K (CuZn5Sn5Pb2) grade and its drying in terms of increasing the use of impure waste from machining as scrap for direct melting. The waste was assessed in relation to individual parameters. The research was carried out on 3 groups of waste, with varying degrees of moisture.

Opis:
The article presents tests on a new lead-free bronze CuSn4Zn2PS, intended for fittings for contact with drinking water, in which the addition of lead was replaced with sulphur. The subject of the experimental work was the production of semi-finished products from this alloy based on the charge coming entirely from waste generated after machining. A specialized pilot line was used for the tests, and after cleaning, the waste was melted and then were continuously cast in the form of rods and hollow rods. The cleaning efficiency was assessed, and the manufactured semi-finished products were subjected to tests, including the assessment of the chemical and mechanical homogeneity and the structure of the test batch of the semi-finished casting products in terms of the possibility of manufacturing products meeting the requirements of technical specifications. The obtained results, both in terms of a stable chemical composition, homogeneous and reproducible mechanical properties, fully compliant with the specifications for fittings bronzes (CC499K), as well as the lack of faults of the obtained semi-finished products, despite a very large share of waste material, indicate the possibility of using the tested recycling method for the production of semi-products of sulphur bronze, which is an alloy that is relatively difficult to manufacture.

Opis:
Experiments using in vitro embryo germination and culture have been designed to investigate the effects of cobalt levels of 0, 100, 200, 400 and 800 μM on some growth parameters and chemical changes in Jatropha curcas seedlings. The results showed that excess cobalt levels in MS media produced visual symptoms of toxicity in J. curcas seedlings after 7 d with increasing levels of cobalt ion. The fresh weights of cotyledons and radicles were significantly affected except for hypocotyls at the cobalt concentration of 100 μM. The activity of superoxide dismutase (SOD) significantly increased in the radicles when compared to the control, but decreases in the activity of the hypocotyls were found at the tested cobalt levels. Increase of guaiacol peroxidase (GPX) activity in the cotyledons and hypocotyls was observed at the tested cobalt levels, but a decrease of the activity in the radicles except for at cobalt concentration of 100 μM. Increase in the activity of catalase (CAT) of radicles with increasing cobalt concentrations, and a significant decrease in activity in the hypocotyls was also observed. Increase in phenylalanine ammonia-lyase (PAL) activity of cotyledons and radicles with increasing cobalt concentrations in the range 100-800 μM, but a decline in the activity of hypocotyls was also observed when hypocotyls at the cobalt concentrations of 400 and 800 μM. The present results indicated that SOD, GPX, CAT, and PAL may play an important role in the defensive mechanisms of Jatropha curcas seedlings exposed to excessive cobalt. These findings will help to provide useful bioassays to help in assessment of cobalt contamination in agricultural environments.
