Rowieńscy alias Wojuccy herbu Gąska
No full textThe Gąska coat of arms first appeared in written sources in 1402. On April 3 of that year, witnesses appeared at the land court in Sieradz to testify to the family affiliation of Przybek of Kościanki. In the second pair, the accused summoned Janusz of Lichawa and Jan of Wodzierady, both bearing the Gąska coat of arms. In 1403 and 1405, Stanisław same coat of arms, along with the aforementioned Janusz of Lichawa. Bartosz Paprocki traced the origin of the coat of arms to the legend of the Capitoline geese, which saved Rome from a barbarian invasion. He also gave it alternative names: Paparona (1578) and Budzisz (1584). The circle of ancestors known to him was small. Aside from the Chodowski family of Łęczyca, he listed only a few families from Sieradz: the Kamionomojski, Parzniewski, Pstrokoński, and Wojucki families. In the Middle Ages, in the Sieradz region, the name Równa was used twice in reference to the Gąska coat of arms, deriving from the village of Równa on the Swędrnia River, along the route from Błaszki to Sieradz.
The Rowieński family, also known as Wojucki, who lived on the border of the Kalisz and Sieradz regions, represents a typical noble family from this area. Despite two advantageous marriages, income from municipal courts, and the ecclesiastical career of one of its members, the family did not accumulate significant wealth.

Declaration regarding the use of GAI tools: not used Herb Gąska pojawił się w źródłach pisanych w 1402 r. Na rokach ziemskich w Sieradzu 3 kwietnia stanęli świadkowie Przybka z Kościanek celem zeznania jego przynależności rodowej. W drugiej parze naganiony powołał Janusza z Lichawy i Jana z Wodzierad z klejnotu Gąski. W 1403 i 1405 r. z tego klejnotu Stanisławowi z Chrzanowic – obok wspomnianego już Janusza z Lichawy – świadczył także Paweł z Rzechty i Drużbina. Bartosz Paprocki powiązał genezę herbu z legendą o gęsiach kapitolińskich, które uratowały Rzym przed najazdem barbarzyńców. Nadał mu też kolejne nazwy: Paparona (1578) i Budzisz (1584). Znany mu krąg rodowców był nieliczny. Poza Chodowskimi z Łęczyckiego, autor zaliczył do nich tylko kilka rodzin sieradzkich: Kamionomojskich, Parzniewskich, Pstrokońskich i Wojuckich. W ziemi sieradzkiej w średniowieczu obok nazwy herbu Gąska użyto dwukrotnie nazwy Równa, pochodzącej od wsi nad rzeczką Swędrnią, przy szlaku z Błaszek do Sieradza.
Rodzina Rowieńskich alias Wojuckich, siedząca na pograniczu Kaliskiego i Sieradzkiego, prezentuje przeciętną rodzinę szlachecką z tego terenu. Nie dorobiła się większego majątku, mimo dwóch korzystnych małżeństw, dochodów z sądownictwa grodzkiego i kościelnej kariery jednego z jej przedstawicieli.

Determination of the influence of calibration sphere parameters on the results of articulating probe head qualification
No full textThe qualification of probe heads before the measurements performed with their usage is now a standard procedure. It is used for correction of probe head’s and measuring tip systematic errors. The calibration sphere, which is used for this process, should have adequately small form errors. However, it is not always possible to use a highly accurate spheres and it is a common practice to use a sphere that was provided by the manufacturer of the CMM for a long time. This is why, the authors have tried to answer the question about the impact of the calibration sphere inaccuracies on the results of probe head qualification process
Identification of the Influence of IPA Rinsing Times on Surface Roughness of SLA-Printed Parts Made of Different Materials
No full textThis study investigates the influence of isopropyl alcohol (IPA) washing time on the surface roughness of stereolithography (SLA)-printed parts fabricated using the Formlabs Form 3B+ printer. Three photopolymer resins provided by the manufacturer were evaluated: Gray, Tough 2000, and Rigid 10K. Samples were printed in standardized geometries and post-processed under controlled conditions, with IPA washing times ranging from 6 to 30 min, followed by UV post-curing. The surface roughness parameters (Ra, Rz, Rt, and RSm) were measured using a Taylor Hobson Form Talysurf i-Series profilometer under metrologically controlled conditions. The results revealed a clear correlation between increased IPA exposure time and improved surface finish, though the magnitude and monotonicity of this effect were material dependent. Rigid 10K exhibited the most consistent reduction in roughness with longer washing, while Tough 2000 showed substantial improvement with extended durations but also demonstrated temporary surface degradation at intermediate wash times. Gray resin achieved near-optimal roughness after moderate rinsing, with orientation-dependent differences observed. The findings indicate that the careful optimization of washing duration can significantly enhance the surface quality in SLA prints, potentially eliminating the need for secondary finishing processes. The implications are relevant to both industrial and medical applications where dimensional fidelity and surface smoothness are critical. Recommendations for optimal washing durations are proposed for each material, and directions for further research are outlined

No full textThe modelling of the measuring point reproduction error for optical coordinate measuring machines
No full textCoordinate measuring machines (CMMs) are the most common measuring systems used for assessing the compliance of manufactured components with their geometrical specifications. Optical CMMs are currently gaining popularity as they enable fast and contactless measurement with accuracy almost as high as in case of tactile measurement. During the performing of measurement, the points at which the measurement is conducted are usually not exactly at the intended location, but due to different impacts (error sources), they are in the area surrounding this location. This paper presents a method for modelling the reproduction of point coordinates as probability ellipses geometrically limiting the area in which the actual measurement points may lie. Different mathematical algorithms for the description of these ellipses were examined and a discussion on the selection of the best method is presented in this paper

Numerical analysis of construction of drainage system for precipitation waters
No full textProgressive implements which make possible advanced geotechnical analysis, induced the author to verify previously accepted engineering solutions of construction of rain waters drainage system with the use of reinforced concrete walls and horizontal geogrids. The quantitative analysis of stress distribution in ground medium around the drainage system was performed in numerical model with the use of finite element method . This analysis confirmed previous – intuitive and qualitative - assumptions of the technical design. The application of reinforced concrete walls, transmission of ground lateral pressure to the soil below and the above drainage system, result in twofold reduction of horizontal components of ground stresses in area between reinforced walls and the drainage. The usage of two layers of geogrid over the drainage system made possible strain relief of this system (in the middle, the most sensitive zone) in vertical direction of about 75%
The Importance of Differences in Results Obtained from Measurements with Various Measuring Systems and Measuring Modes in Industrial Practice
No full textThis paper presents the results of preliminary tests carried out in an organization producing products for the automotive industry. From the many available systems used in this research, different values of results were obtained; these differences cause doubts among people deciding about the process approval and start of production. The main aim of the research presented in the article is to determine the influence of various factors on the measurement results, especially to compare the results of measurements obtained with the optical sensor, which is used during measurements with the use of a multisensor measuring machine. The results obtained with the use of the height gauge, which is used alternatively in the organization, raise further doubts. Experience has shown that the methodology and definition of the alignment during the measurement, which is different for each of the systems, have a great influence
