During the slag refining process, in the real systems, the complex processes of mass exchange appear. Some relations between the stimulators in the environment - slag - metal system allow to initiate mass exchange reactions in the process of slag refining. Due to this kind of influences there is a possibility of direction and control of melting copper and it’s alloys.
The development of electromobility is a challenge for the power system in both technical and economic-market terms. As of today, there are no analyses to determine the power necessary to supply the planned infrastructure and to estimate the incentives and economic benefits resulting from the modification of the settlement method. The document determining the legal regulations and the obligation to build vehicle charging stations for specific municipalities is the Act on Electromobility and Alternative Fuels. This act estimates that the development of electromobility, due to the specifics including not only individual vehicles, will take place in certain areas. The places which in the first stage will be dedicated to the potential implementation of the concept of electromobility will be municipalities covering large agglomerations. In addition, due to the local aspect, the development of electromobility may take place in the areas of energy clusters’ initiatives, which, using the policy of increasing energy awareness, are aimed at energy production from local renewable energy resources. The planned development of electromobility assumes a systematic increase in the number of electric cars caused by the introduction of support systems. The dynamization of this sector will cause an increase in the demand for electricity. Due to power system reasons, an important factor determining the level of energy consumption depending on the time of day may be an appropriate shape of the pricing for the charging service. Appropriate price list stimulation can affect the behavior of recipients, causing the charging of cars in the off-peak of electricity demand. The aim of the article is to characterize the scale of the phenomenon of electromobility in the context of the emergence of a charging points infrastructure along with the possibility of price-setting stimulation affecting the profile of energy demand. It is also important to consider the challenges and responsibilities of municipalities and energy clusters from the perspective of introducing electromobility.
The purpose of the study was to study the activity of the phytoestrogen genistein (GEN) act- ing on FSHR and LHR in rat ovaries with polycystic ovary syndrome (PCOS). Sixty rats were di- vided into six groups. Rats in the dose group received genistein at a concentration of either 5 (low genistein dose group, L-gen), 10 (middle genistein dose group, M-Gen) or 20 (high genistein dose group, H-Gen) mg per kg of body weight per day. Estrogen group (EG, received 0.5 mg/kg Dieth- ylstilbestrol). Concentration of sex hormones in serum was quantified by enzyme-linked immuno- sorbent assay (ELISA). Expressions of follicle-stimulating hormone receptor (FSHR) and lutein- izing hormone receptor (LHR) protein were determined by immunohistochemistry. Treatment with genistein resulted in a strong stimulation of the concentration of sex hormone in serum. The concentration of progesterone and FSH was signiﬁcantly higher in H-Gen when compared to the PCOS model control group (MG) (P < 0.01). In contrast, the concentration of testosterone, LH and the ratio of LH/FSH decreased in GEN treatment groups compared to MG, the effect was statistically significant, tested by the ANOVA test (p<0.01). For hormone receptor activity, treat- ment with genistein resulted in an improvement of ovarian function with LHR protein expression being enhanced and FSHR protein expression being suppressed. Our results demonstrate that Genistein played a significant role in regulating FSH and LH receptor expression to improve perimenopausal ovarian and uterine function.
The aim of the study was to investigate the relationships between emotional intelligence (EI) and temperament. It was assumed that the two main components of EI – experiential and strategic – have different temperament correlates. One hundred and four Polish university students aged 19 to 26 completed self-descriptive questionnaires of temperament and emotional intelligence. The results confirmed that the relationship with temperament depends on the examined component of EI. Acceptance of emotions (which is a subcomponent of experiential EI) only correlated with two temperamental traits – activity and briskness. Many more dependencies were found in relation to strategic EI. Endurance, strength of inhibition, sensory sensitivity and perseveration turned out to be significant predictors of emotional control, which jointly explained 44% of the variance in results, while perseveration and sensory sensitivity explained 28% of the variance in results on the understanding emotions scale. Based on the results obtained, it can be assumed that the configuration of temperament traits that determines a high capacity for processing stimulation is most conductive to strategic EI. Other propitious traits include those that determine the speed of neural processes, flexibility and ease of adaptation to changing conditions as well as a low sensitivity threshold to sensory stimulus.
