Opis:
In this work the state of archeological and experimental research into slag-pit fournace in the Świętokrzyskie Mountains region was valued. The new archeological concept of "the surface of free solidification" and results of its metallurgical verification were presented. Obtained results constituted piece of evidence supporting the theses connected with the concept of the surface of free solidification of the slag blocks.
W pracy dokonano oceny stanu badań archeologicznych i eksperymentalnych nad piecem dymarskim typu zagłębionego z regionu świętokrzyskiego. Zaprezentowano nową koncepcję archeologiczną "powierzchni swobodnego krzepnięcia" kloców żużlowych i wyniki jej weryfikacji metalurgicznej. Uzyskane wyniki stanowią dowód potwierdzający słuszność tez, wynikających z koncepcji powierzchni swobodnego krzepnięcia.

Opis:
The aim of this study was to determine the impact of slag composition on phosphorus removal from ferrous solutions containing carbon, chromium and nickel. Additions of cryolite, Na3AlF6, were applied for better fluxing and higher phosphate capacity of the slag. An X-ray analysis of final slags formed during dephosphorization of ferrous solutions containing chromium and nickel with CaO-CaF2 or CaO-CaF2-Na3AlF6 mixtures of different chemical compositions was carried out. The equilibrium composition of the liquid and the solid phase while cooling the slags from 1673K to 298K was computed using FactSage 6.2 software. The performed equilibrium computations indicated that the slags were not entirely liquid at those temperatures. The addition of cryolite causes a substantial increase of the liquid phase of the slag. It also has a favourable effect on the dephosphorization grade of hot metal. The obtained results were statistically processed and presented in the form of regression equations.

Opis:
The state of the dislocation substructure of meteorite in which the history of phenomena accompanying the meteorite during its passage through the Earth’s atmosphere is recorded remains unused. The main goal of the presented work is a comprehensive analysis of the dislocation structure of the iron meteorite from the Morasko reserve (Poland, Wielkopolska Voivodeship) by TEM methods to determine the conditions and mechanism of its formation. The work is cognitive in the field of phenomena related to the destruction and deformation of the material in extreme conditions: space and terrestrial space. It can also be useful in the research on the creation of the material with specific mechanical properties, as well as a unique reference material for earth experiments with low-temperature deformation, high-speed deformation, recrystallization processes with short thermal pulses and structure relaxation in conditions of very long time periods.

Opis:
The aim of the study was to verify if the accuracy of weight perception among young women depends on their socioeconomic status and BMI–based weight status. In addition, the survey contained questions whether women were satisfied with their weight and tested if the desire to change weight is affected by real body weight and weight perception. The sample consisted of 1,129 female university students, aged 20–24. BMI was calculated from measured weight and height. The questionnaire contained questions about socio-economic status, weight perception and desired body weight. 71.9% of the surveyed students correctly estimated, 24.2% overestimated and 3.9% underestimated their body weight. Underweight women tended to incorrectly assess their body weight more often than normal weight women or overweight women (43.2% vs. 75.4% vs. 77.2%). Students from families of high socio-economic status slightly more often estimated their weight status correctly than students with average and low status, but the difference was statistically significant only in the case of the factor “mother’s education”. Most of surveyed women expressed the desire to weigh less or/and to have thinner waist, hips or thighs. The desire to be thinner was associated with body weight status and body weight perception.

Opis:
Objective. The aim of the study was to define whether in a group of young women the place of residence in their childhood and adolescence, as well as moving from a rural to an urban area, have affected their biological condition. Materials and method. The data were obtained from 1,305 unmarried and childless women aged 18–25. The respondents were university students. Each person’s height, weight and waist circumference were measured, and the BMI, WHR, and WHtR indices were calculated. A survey was used to collect data on the females’ socio-economic status, their health condition and course of menstruation cycle. Results. In the whole sample, apart from WHR, there was no significant difference in anthropometric characteristics depending on the urbanization degree of the place of residence before commencing studies. In comparing the two groups of women, changing place of residence from a village to a city and from a city to another city, more differences were visible. Women of rural origin presented significantly higher values of BMI, waist circumference and WHtR than those from the city. They were also more frequently characterized by overweight and abdominal obesity. The women from other cities were characterized by underweight and too low amount of abdominal adipose tissue. Health problems were found in both groups. Students of rural origin more rarely declared changes in body weight and health condition after beginning studies. Students of urban origin were more often affected by sleeping problems and spine pains. Conclusions. The results of the study do not indicate that a change of place of residence has a stronger effect on the biological condition of rural women than their urban peers.
