Gender, media, and mixed martial arts in Poland: the case of Joanna Jędrzejczyk

Recent growth in the media visibility of female combat sport athletes has offered a compelling site for research on gender and sport media, as women in deeply masculinized sports have been increasingly placed in the public spotlight. While scholars in the Anglophone West have offered analyses of the media framing of this phenomenon, little work has been done outside these cultural contexts. Thus, in this paper we offer a qualitative exploration of how Joanna Jędrzejczyk, a Polish champion of the Ultimate Fighting Championship, has been represented in Polish media. Our findings reveal a relatively de-gendered, widely celebratory account, primarily framed by nationalistic discourse–findings we ascribe to both the particularities of the sport of mixed martial arts as well as the historic nature of Jędrzejczyk’s success

Impact of initiation method of bulk emulsion explosive on the velocity of detonation based on Emulinit 8L

W artykule przedstawiono wyniki badań wpływu zastosowanego środka inicjującego na prędkość detonacji materiału wybuchowego. Przedmiotem badań był materiał wybuchowy emulsyjny luzem Emulinit 8L produkowany przez firmę Nitroerg S.A. z Bierunia. W ramach badań przeanalizowano przebiegi detonacji na całej długości ładunków MW dla wszystkich analizowanych przypadków oraz charakterystykę rozbiegu materiału do prędkości maksymalnej.This paper presents the results of analysis of the impact of initiation method on the detonation velocity of explosives. The subject of research was Emulinit 8L emulsion explosive manufactured by Nitroerg S.A. from Bieruń. Within the framework of the presented research, detonation characteristics on the entire length of explosive’s samples as well as characteristics of detonation run-up to maximum velocity were analyzed

Is water in dental units microbiologically safe?

Background: Water supplied to the dental units must be of sufficient quality. The article presents the results of the microbiological analysis of cold municipal water which flows into a patient’s disposable mouthwash cup, and demineralized water which flows through a waterline into the tool panel of a dental unit from the tank placed in the water group. Material and Methods: In order to assess the degree of purity (impurities) of water used in dental units, 2 series of microbiological tests were carried out in 6 dental surgeries from April to June, 2013. The water samples for microbiological testing were collected into sterile microbiological bottles in accordance with the current methodology. The water for the tests was collected from a sterile cup-filling tap (municipal water) and from an air/water syringe (demineralized water). The bacteria were cultured according to the Polish Standards – PN-EN ISO 6222, PN-EN ISO 9308-1, and PN-EN ISO 16266. Results: In the tested samples of water numerous psychrophilic bacteria (max 29 100 CFU/ml) and mesophilic bacteria (max 24 700 CFU/ml), including single coliforms, were found. Conclusions: The results show that water delivered to a dental unit should be periodically tested bacteriologically and in terms of physical and chemical properties. Water systems of dental units should also be periodically disinfected to eliminate bacteria and biofilm. Med Pr 2015;66(6):763–77

Kinetics and Adsorption Isotherms of Amine-Functionalized Magnesium Ferrite Produced Using Sol-Gel Method for Treatment of Heavy Metals in Wastewater

This study is focused on the kinetics and adsorption isotherms of amine-functionalized magnesium ferrite (MgFe2O4) for treating the heavy metals in wastewater. A sol-gel route was adopted to produce MgFe2O4 nanoparticles. The surfaces of the MgFe2O4 nanoparticles were functionalized using primary amine (ethanolamine). The surface morphology, phase formation, and functionality of the MgFe2O4 nano-adsorbents were studied using the SEM, UV-visible, FTIR, and TGA techniques. The characterized nanoparticles were tested on their ability to adsorb the Pb2+, Cu2+, and Zn2+ ions from the wastewater. The kinetic parameters and adsorption isotherms for the adsorption of the metal ions by the amine-functionalized MgFe2O4 were obtained using the pseudo-first-order, pseudo-second-order, Langmuir, and Freundlich models. The pseudo-second order and Langmuir models best described the adsorption kinetics and isotherms, implying strong chemisorption via the formation of coordinative bonds between the amine groups and metal ions. The Langmuir equation revealed the highest adsorption capacity of 0.7 mmol/g for the amine-functionalized MgFe2O4 nano-adsorbents. The adsorption capacity of the nanoadsorbent also changed with the calcination temperature. The MgFe2O4 sample, calcined at 500 °C, removed the most of the Pb2+ (73%), Cu2+ (59%), and Zn2+ (62%) ions from the water
