Abstract

A two-parameter continuation method was developed and shown in the form of an example, allowing determination of Hopf bifurcation sets in a chemical reactor model. Exemplary calculations were made for the continuous stirred tank reactor model (CSTR). The set of HB points limiting the range of oscillation in the reactor was determined. The results were confirmed on the bifurcation diagram of steady states and on time charts. The method is universal and can be used for various models of chemical reactors.

Abstract

The article presents the results of the questionnaire research carried out after the first and repeated after the second semester of crisis remote education, conducted at The Maria Grzegorzewska University. Students participating in the study indicate a significant increase in their IT competences and the level of remote education. They declare a similar, high level of commitment and independence during classes. They indicate that commitment, activity, contact with the lecturers, regularity and quality of work, as well as the adequacy of the grades given are better during traditional education, although their timeliness is higher during distance education. The computer equipment of students and the way of accessing the Internet have not changed significantly. 20% of respondents admitted to using unauthorized assistance during exams. In the statements of students, on the one hand, there is a desire to return to social contacts and traditional classes, and on the other hand, a desire to maintain remote education, associated with the comfort of home-based learning and independence.

Abstract

The aim of this study was to determine if reticulorumen ph, temperature and cow activity registered before calving can serve as indicators of diseases after calving.

The cows were selected according to those fitting the profile of having had two or more lactations (on average 2.9±0.13 lactations), from 60 to 0 days before and the first 30 days after calving, and being clinically healthy. The clinical examination (identification of diseases after calving) was performed from 60 days before calving to 60 days after calving. Diseases after calving were diagnosed based on clinical symptoms specific to these diseases. The pH and temperature of the contents of the cow reticulorumens and cow activity were measured using specific smaX-tec boluses manufactured for animal care.

We found that the highest pH and temperature before calving can serve as biomarkers of healthy cows after calving. The lowest reticulum temperature before calving can serve as an indicator of MF after calving. A positive correlation of reticulum pH and temperature before calving can serve as biomarkers of PR. Decreasing cow activity before calving can serve as an indicator of diseases after calving. For calving prognosis, temperature of the reticulorumen can be used; it decreased 6–7 days before calving.

Abstract

The aim of this study was to evaluate the efficacy of thermography in assessing the impact of regular physical effort on changes in the body surface temperature of the upper body parts of young racehorses. The study involved monitoring 33 racehorses aged 3 years in 3 imaging sessions over a period of 3 months. Temperature measurements of the neck and upper part of the forelimbs and hindlimbs from both sides were taken just before and after training. Three regions of interest (ROIs) located at the base of the neck, elbow and quarter on both sides of the body were analysed. Before physical effort, the average temperatures in all ROIs did not differ significantly between the right and left side of the body. After physical effort average surface temperatures of the left side of the elbow and quarter were significantly higher compared to the opposite side and the temperature at the base of the neck was higher on the right side in comparison to the left side (p<0.001). Body surface temperatures of all ROIs after physical effort significantly (p≤0.001) increased, with the greatest increase observed in the elbow (4.7°C) and the lowest in the base of the neck (3ºC). All regions demonstrated a positive correlation between average surface temperatures on the left and right side of the body, before and after training. There was a strong positive correlation between the average temperatures in the analyzed ROIs after physical effort with the strongest correlation between the elbow and quarter (r=0.773) and the weakest between the quarter and base of the neck (r=0.474). In conclusion, our study revealed that thermography remains a feasible diagnostic modality for identifying changes in upper parts of the body in response to physical effort and can therefore provide valuable insights into the assimilation of training regimes by the equine physiology.

Abstract

Studies on Ichneumonidae were carried out in the years 1999-2001 in the fruit-growing environment and in shrubs growing in its closest surroundings. The occurrence of 45 Pimplinae species was recorded (32.8% of the Polish fauna of this subfamily) and one species each ofDiacritinae and Poemeniinae subfamilies. Qualitative and quantitative analyses of the Ichneumonidae groups occurring on fruit trees and shrubs were carried out.
