W artykule zwrócono uwagę na zależność między prospołeczną i proekologiczną działalnością przedsiębiorstwa a jego konkurencyjnością. Zauważono, że idea społecznej odpowiedzialności i zrównoważonego rozwoju przedsiębiorstwa poprawia rozpoznawalność firmy, przyciąga najlepszych pracowników, zwiększa siłę przetargową wobec dostawców oraz sprzyja wzrostowi lojalności klientów, co przekłada się na powtarzalność decyzji zakupowych, a tym samym do wzrostu przychodów przedsiębiorstwa.

The article deals With the relationship between prosocial and proecological activity of an enterprise and its competitiveness. It has been noted that the idea of social responsibility and sustainable enterprise development increases the company recognition, attracts the best employees, enhances the bargaining power with suppliers and fosters customer loyalty, which translates into repeatability of purchasing decisions and thus into the growth of the company revenue.

The aim of this work was to obtain Ni-Re binary alloy by a simple method of electrodeposition. Nickel - rhenium alloys have been deposited from nickel sulfamate and ammonium perrhenate electrolyte with citrate-anion additives. The effect of magnetic field superimposed during electrodeposition was studied. The impacts of that parameter on hydrogen evolution process for obtained Ni-Re alloys were examined. The deposited layers were determined by optical and scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray fluorescence (XRF).

Celem pracy było uzyskanie stopów Ni-Re metoda osadzania elektrolitycznego. Stop niklowo renowy osadzano z elektrolitu zawierającego sulfaminian niklu oraz nadrenian amonu. Stosowano bufor cytrynianowy. Badano wpływ przyłożonego zewnętrznego pola magnetycznego podczas osadzania stopu na wydzielanie wodoru na tak uzyskanym stopie. Badano osadzone warstewki stopowe za pomocą mikroskopu optycznego oraz mikroskopu skaningowego i metodami XRD oraz XRF.

The expression of genes encoding opioid precursors: proopiomelanocortin (POMC), proenkephalin (PENK) and prodynorphin (PDYN) was studied in the porcine endometrial explants in the presence or absence of selected cytokines (interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor α (TNFα)) on days 10–11, 12–13, 15–16 of the oestrous cycle and pregnancy. In pregnant pigs, these days among others are important for 1. migration of the embryos, 2. maternal recognition of pregnancy and 3. the onset of implantation, respectively. During the oestrous cycle, the basal (in the absence of cytokines) mRNA expression of PDYN, but not POMC or PENK was increased on days 15–16 compared to days 10–11. During pregnancy, the gene expression of POMC increased on days 10–11 and 15–16 (vs days 12–13), but PENK – on days 12–13 and 15-16 (vs days 10–11) as well as PDYN – on days 15-16 (vs days 12–13) decreased. The endometrial expression of studied genes was influenced by cytokines. The expression of PENK was stimulated by IL-6 in all studied days of the cycle as well as on days 10–11 and 12–13 of pregnancy. In turn, the PENK mRNA expression was increased by TNFα on days 10–11 and decreased by IL-1β on days 15–16 of pregnancy. The POMC expression was decreased by IL-1β on days 12–13, but increased by both IL-6 and TNFα on days 15–16 of the cycle. The PDYN mRNA expression in endometrial explants was increased by IL-1β on days 10–11 of the cycle. These results indicate that the opioid system is involved in the local regulation of uterine functions during the oestrous cycle end early pregnancy in pigs.
