Opis:: Cathodic electrolytic plasma hardening is a novel thermochemical surface modification and hardening process, used to increase wear resistance and surface hardness of metallic components in a local area of interest. The heating efficiency is related with the plasma nozzle design, applied current and electrolyte. The nozzle design is also a critical factor for the hardening of complex shapes, such as gears and camshafts. In this work, lobes of camshafts, fabricated from several cast iron and steel grades were hardened by cathodic electrolytic plasma hardening in aqueous carbonate electrolyte, using a specific plasma nozzle. The camshafts were attached to CNC lathe for turning them in the horizontal axis. In order to optimise heating and to achieve the ideal flowing and wetting by the electrolyte of the lobe case, the ceramic ellipse-shaped nozzle outlet was designed. As a result of preliminary studies, external surface of lobes was heated and subsequently quenched by electrolyte. The hardness of processed surface was in the range of 50-60 HRc for the different camshafts. No distortion was observed on the surface of lobes. Hardness depth was measured to be from 0.1 mm to 5 mm for several lobes.

Opis:: High carbonate content in soil negatively affect plant growth, because the availability of nutrients is restricted due to high pH. The present investigations were carried out to reveal possible alleviating effects of the exogenous root inoculation PGPRs on development and physiology of soilless-grown grapevines cultivated under alkaline stress in controlled glass house. pH of growth medium was increased from 7.5 to the values ranging from 7.9 (control) to 8.1 (A18) according to the bacterial inoculations by NaHCO3 supplementations. Bacteria inoculations did not result in statistically significant differences in pH values of growth media. The bacterial population density found in the rhizosphere of grapevines ranged from 6 × 108 CFU mL−1 (M-3) to 9 × 108 CFU mL−1 (Ca-637). The highest value of shoot thickness was obtained from Ca-637 (5.3 mm), followed by A18 (5.2 mm), while M3 did not significantly affected the shoot thickness. The greatest pruning residue per vine was obtained from A18 treatment (81.5 g), followed by Ca-637 (80.8 g) while the lowest value was determined in control. Vine yield was the greatest with A18 (1128 g) treatment and was followed by Ca 637 (1059 g). Considering the general observations, root inoculation of PGPRs A18 and Ca-637 may be recommended in enhancing bioremediation of alkali growth media.

Opis:: Consumption of high-fructose corn syrup (HFCS) in the diet is a causal factor in the development of abdominal obesity; however, the molecular mechanism behind this association is still up for debate. This study evaluated the metabolic disturbances that are caused by HFCS on adipose tissue as well as the possibility of kefir as a therapy to prevent these metabolic disturbances. Male Wistar rats were divided into four groups: control, kefir, HFCS, and HFCS+kefir. HFCS (20%, w/v) was given in drinking water and kefir (1 mL/100 g body weight) by gastric gavage daily for 8 weeks. Levels of insulin signaling, inflammation, and apoptosis-associated proteins of adipose tissues were determined with Western blot and immunohistochemical techniques. Gene expressions were evaluated with semi-quantitative real-time polymerase chain reaction (qRT-PCR). The indirect terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) method was used to assess changes in apoptotic cells, and hematoxylin/eosin staining to determine adipocyte number and diameter. Accordingly, HFCS boosted protein kinase B (Akt) and p-Akt while reducing nuclear factor κB (NF-κB), and tumor necrosis factor alpha (TNFα) levels and kefir treatment restored Akt induction in HFCS-treated rats despite raising NF-κB, and TNFα. Increased expression of Akt and B-cell lymphoma-2 gene (Bcl2) was contrasted with decreased expression of Nfkb, Tnfa, tumor protein 53 gene (p53), and caspase-8 gene (Casp8). Furthermore, while there was a marked reduction in TUNEL-positive cells in the HFCS group, the number of such cells was greater in the HFCS+kefir group. These results show that HFCS intake suppresses apoptosis in adipose tissues, which may be responsible for tissue development and abdominal obesity and may be reversed with kefir administration due to the activation of apoptosis-associated genes and proteins.
