The impact of Pseudomonas koreensis IB-4, Pseudomonas sp. UOM 10, Enterobacter ludwigii BLK, synthesizing indolylacetic acid on the growth and biochemical parameters of the forage plant mogar (Setaria italica (L.) P. Beauv.) when modeling water scarcity in laboratory conditions was evaluated. All the strains used had a positive effect on the photosynthetic apparatus, increasing the total content of chlorophylls a and b and preventing the development of oxidative stress caused by drought by reducing the level of malondialdehyde (MDA),, which, ultimately, was expressed in the accumulation of raw shoot mass in plants.

The present study’s objective was to evaluate the impact of Bunium incrassatum roots’ powder (Talghouda) as a dietary supplement on the evolution of biological, biochemical, and histological parameters in female Wistar rats. The animals were divided into two groups and given an orally standard diet supplemented with 15% of Bunium incrassatum roots powder, daily for 15 days. The obtained results showed that the roots of Bunium incrassatum induced an increase in the body and organs weight of Diet rats compared to the control, as well as effects on the biochemical parameters, characterized mainly by a significant increase in the glycaemia (+44.44%), triglyceride (+56.81%), cholesterol (+11.90%), LDL (+4.08%) and HDL (+11.53%)and a decrease in creatinine (-3.65%), TGO (-6.92%) and TGP (-58.73%). In the histological study of organs, the thyroid of diet rats revealed large thyroid follicles, the colloid of the follicles was more or less developed compared to the control rats. Through the obtained results, it can be concluded that a standard diet supplemented with 15% of Bunium incrassatum roots powder may have a positive effect on biological, biochemical, and histological parameters

Aim. A complex study of the impact of the consortium of humus-forming microorganisms in the composition of the biological preparation Extrakon, introduced into the rhizosphere, on the intact plants and plants, infected with phytopathogenic microorganisms Pseudomonas syringae pv. atrofaciens st. 9771 and Acholeplasma laid- lawii var. granulum st.118. Methods. Microbiological, physiological and biochemical, biophysical, statistical. The impact of the multifunctional biological preparation Extrakon, introduced into the soil, was studied using physiological and biochemical indices, in particular, catalase and peroxidase activity of tissues and the content of chlorophylls a and b, the photochemical activity of the photosynthetic apparatus and the grain performance of the intact spring wheat plants, Pechernianka cultivar, and plants, infected with phytopathogenic microorgan- isms P. syringae pv. atrofaciens st. 9771 and A. laidlawii var. granulum st. 118. Results. The application of the consortium of humus-forming microorganisms in the composition of the biological preparation Extrakon resulted in registered stabilizing protective impact on the pigment composition of the leaves of spring wheat plants and their photochemical activity, especially when infected with phytopathogenic bacteria. If the wheat plants were in- fected on the background of the introduction of preparation Extrakon into the soil, the losses in grain performance were reduced. Conclusions. The biological preparation Extrakon neutralizes the destructive effect, conditioned by the phytopathogens of species P. syringae pv. atrofaciens st. 9771 and A. laidlawii var. granulum st. 118, on the photosynthetic apparatus of the host plant. This impact leads to the increase in the content of pigments in the leaves and induces the development of the resistance to damage in the conditions of the oxidative stress with the increase in the level of antioxidant enzymes activity, especially catalase, in the tissues. This is accompanied with the increase in the photosynthetic activity of leaves and the grain performance of plants.

The content and dynamics of chlorophylls a and b of the photosynthetic organ (leaf) of representatives of the genus Canna L. were studied at different phases of plant growth and development: at the beginning of the growing season, in the generative phase, at the end of the growing season under conditions of Kryvyi Rih. A high content of chlorophylls in the leaves of most of the studied canna varieties was noted, compared with the species (with the exception of C. indica). A common trend for canna plants was an increase in the total number of chlorophylls in generative phase. Varieties of canna Capter, Vesolyye notki, Richard Wallis, which have litle leaf parameters, were characterized by a low total content of photopigments during the growing season and chlorophyll b in the generative phase, which indicates a significant sensitivity of plants to arid conditions in the region. Plants of the Fauervogel, Rosenkranzen and Krymskiye Zori varieties (with large leaf blades) were characterized by a high concentration of green pigments during the growing season, and chlorophyll b in the generative phase, this feature in the functioning of the photosynthetic apparatus is consistent with a high assessment of the level of adaptation of these plants in drought conditions. Therefore, indicators of the state of the assimilation apparatus of plants of the genus Canna L. can be used to determine their level of fitness for moisture deficiency during introduction studies.

Special Case

Digitalization is a megatrend, but there is relatively little knowledge about its consequences for service work in general and specifically in knowledge-intensive business services (KIBS). We studied the impact of digitalization on psychological consequences for employees in tax consultancies as a special case of KIBS. We compare two tax consulting jobs with very different job demands, those of tax consultants (TCs) and assistant tax consultants (ATCs). The results show that the extent of digitalization at the workplace level for ATCs correlates significantly positively with their job satisfaction. For TCs, the same variable correlates positively with their work engagement. These positive effects of digitalization are mediated in the case of ATCs by the impact on important job characteristics. In the case of TCs, which already have very good working conditions, the impact is mediated by the positive effect on self-efficacy. Theoretical and practical consequences of these results are discussed.

Resistance To Penetration

The effects of mechanical perforation densities by extracting soil cores through an aerator Vertidrain with a working width of 1.6 m and equipped with hollow tines spaced of 65 mm, were studied on a sandy soil of a grassy sward in the Golf Course El Kantaoui in Sousse (Tunisia). The mechanical aeration was performed at two densities: 250 and 350 holes/m2. The cone penetration resistance and soil water infiltration were measured. These parameters were performed at initial state before aeration (E0) and then on the 10th, 20th and 30th day after aeration. These results showed that perforation density of 350 holes/m2 had a positive effect on the soil by reducing its cone resistance to penetration compared to the initial state (Rp = 14.8 daN/cm2). At 5 cm depth the decrease in resistance to penetration was 34% and 43% on the 10th and 20th day after aeration, respectively. However, on the 30th day after aeration the soil resistance to penetration tended to grow and its value compared to the initial state decreased only by 21 and 26%, respectively, at 5 and 15 cm of depth only by 10% and 9% with 250 holes/m2 density. The soil water infiltration made a good improvement after aeration compared to the initial state. This parameter increased from 4.8 cm/h to 8.3, 10.9 and 13.1 cm/h with 250 holes/m2 density and to 10, 12.9 and 14.8 cm/h with 350 holes/m2 density on the 10th, 20th and 30th day following the aeration.

Efficiency Indicators

One of efficiency indicators of grain grinders is grain granulometric composition. The basis of mixed fodder is crushed grain, the particles of which must have a leveled granulometric composition for subsequent mixing and obtaining a high-quality feed mixture. In agricultural production, hammer crushers are widely used, in which the destruction of grain occurs due to the impact of a hinged hammer. The main disadvantage of these crushers is that not the entire surface of the hammers is involved in grinding, thus reduces grinding process efficiency. A slightly different principle of material destruction is laid down in the basis of the proposed design of the shock-centrifugal grinder. Main work is performed by flat impact elements located on the rotor, which serve to accelerate crushed particles with subsequent impact of them on the bump elements. An important step in the design of new constructions of shock-centrifugal grinders is to determine size and location of the impact elements on the rotor, without which the grinding process is not possible. In the calculation method presented, the dependencies for determining the velocities and angles of a single particle flight from the surface of a flat impact element for its specified dimensions are proposed. Two variants of an impact element location on the rotor are considered and analyzed: radial and at an angle in the direction of rotor rotation. As a result of research carried out, it is noted that in the case of inclined position of an impact element on the rotor an increase in flight speed and flight angles change in crushed particles, which gives the opportunity to have a positive effect on grinding process.

This work involves an analysis of high-chromium high-temperature deformable wieldable nickel alloys for use in GTE repair assemblies. It is shown that the alloys EP868 (VZh98) and Haynes 230 can be used in welded assemblies with an operating temperature of 800-1100 °C. The alloys Nimonic 81, Nimonic 91, IN 935, IN 939, and Nicrotan 2100 GT also have a high potential for use in welded assemblies. They are characterized by a combination of good weldability, high-temperature strength, and resistance to scaling. There have been conducted studies on high-temperature salt corrosion of model nickel alloys. They allowed establishing the patterns of the impact of base metal alloying with chromium, aluminum, titanium, cobalt, tungsten, molybdenum, niobium, tantalum and rare earth metals on the critical temperature of the start of salt corrosion Tcor and the alloy mass loss. It has been established that alloys with a moderate concentration (13-16%) of chromium can possess satisfactory hightemperature corrosion resistance (HTC resistance) under the operating conditions of ship GTE. The HTC resistance of CrAl-Ti alloys improves upon reaching the ratio Ti/Al ˃ 1. Meanwhile, the ratio Ti/Al ˂ 1 promotes the formation of corrosion products with low protective properties. The positive effect of tantalum on the HTC resistance of alloys is manifested at higher test temperatures than that of titanium, and the total content of molybdenum and tungsten in alloys is limited by the condition 8Mo2 – 2W2 = 89. The presence of refractory elements stabilizes the strengthening phase and prevents formation of the ɳ-phase. However, their excess promotes formation of the embrittling topologically close packed (TCP) phases and boundary carbides of an unfavorable morphology. Based on the studies of the HTC resistance, there has been identified a class of model high-temperature corrosionresistant nickel alloys with a moderate or high chromium content (30%), Ti/Al ˃ 1, and a balanced content of refractory and rare-earth elements.

BACKGROUND It is necessary to cope with situations in daily life to prevent stress-related health consequences. However, coping strategies might differ in their impact on dealing with stressful situations in daily life. Moreover, the effect of coping strategies on situational coping might differ between women and men. OBJECTIVE The aim of this study was to investigate the impact of coping strategies on situational coping in everyday life situations and to investigate gender differences. METHODS An ecological momentary assessment study with the mobile health app TrackYourStress (TYS) was conducted with 113 participants. Coping strategies were measured at baseline with the coping scales Positive Thinking, Active Stress Coping, Social Support, Support in Faith, and Alcohol and Cigarette Consumption of the Stress and Coping Inventory (SCI). Situational coping was assessed by the question “How well can you cope with your momentary stress-level” (slider 0-100) in daily life over four weeks. Multilevel models were conducted to test the effects of the coping strategies on situational coping. Additionally, gender differences were evaluated. RESULTS Positive Thinking (P=.03) and Active Stress Coping (P=.04) had significant positive impacts on situational coping in the total sample. For women, only Social Support had a significant positive effect on situational coping (P=.046). For men, only Active Stress Coping had a significant positive effect on situational coping (P=.001). Women had higher scores on the SCI scale Social Support than men (P=.007). CONCLUSIONS These results suggest that different coping strategies could be more effective in daily life for women than for men, which should be considered in the development of interventions aimed at reducing stress consequences through coping. Interventions taking gender into consideration might lead to better coping-outcomes than generalized interventions.
