title: Database of the convergence analysis results of the nonstandard approximation of the generalized Burgers–Huxley equation for the solution bounded within [0, γ^(1/p)].

description: Presented dataset is a result of the convergence analysis of the Mickens-type, nonlinear, finite-difference discretization of a generalized Burgers–Huxley partial differential equation. The generalized Burgers–Huxley equation is a diffusive partial differential equation with nonlinear advection and diffusion. The boundary problem for this equation possesses travelling-wave solutions that are positive and bounded. Only a few travelling-wave solutions of such model are known in exact form, therefore, the construction of the numerical methods that preserve properties of the mathematical model are highly desirable.
The complete convergence analysis of the constructed nonstandard difference scheme is available in the paper: On the convergence of a finite-difference discretization a la Mickens of the generalized Burgers–Huxley equation (2014) Vol. 20, No. 10, 1444–1451, http://dx.doi.org/10.1080/10236198.2014.936319.
We provide nonstandard approximation of the travelling wave solution bounded within [0, γ^(1/p)]. The dataset consists of text files (.txt) with simulation results which contain the maximum-norm errors. Results are obtained for couple of sets of model parameters:  α, γ, p and the space interval [-20,20]. Time interval is set to be [0,20]. Each file contains six results for different combination of time and space steps which satisfy the convergence conditions derived in the above paper.

title: The assessment of microbiological antimicrobial properties of PE film loaded with nanozinc filler

description: The dataset contains the results of a single series of determinations of the antimicrobial properties against E. coli and S. aureus of polyethylene films containing the nanozinc filler.
Squares with a side of 4 cm were cut from the tested material. and sterillized sterilized under UV light (30 minutes on each side). Then 0.2 mL of inoculum was applied to each of the squares. Immediately after inoculation, materials marked "0 hr contact time" transferred to 10 mL of PBS solution and shaken 5 x 5 seconds using a vortex. Serial ten-fold dilutions and deep streaks were made on TSA. The plates were incubated in an incubator for 24 hours at 37 ° C. Other materials marked as "contact time 24 hours" incubated with the inoculum in an incubator for 24 h. at 37 ° C, and then the procedure for an exposure time of 0 hours was carried out for them. The test results show that the filler used in the production of polyethylene films does not have antimicrobial activity.

title: Mechanical properties of VL E27 steel for shipbuilding – fracture toughness test in 0°C

description: One of the basic divisions of steels used for ship hulls and ocean engineering structures is the division into: normal strength steels, high strength steels and extra high strength steels. The belonging to the group is determined by the mechanical properties of the steel, such as: yield point, ultimate strength and plastic elongation after fracture. The steels in each group are divided into categories, differing in the minimum required breaking energy at a specific temperature, determined in the Charpy test. For applications on a more responsible hull structure or offshore structure, additional steel tests may be required - determination of fracture toughness. In the shipbuilding industry, it is most often CTOD (Crack Tip Opening Displacement) test.
The published data concern testing the fracture toughness of VL E27 steel for shipbuilding, with  nominal thickness of 35 mm. It is the first steel from the group of high strength steels. It is characterized by an early low carbon content, as for hull steels, which is one of the reasons for its high ductility. The average carbon content in the tested material was 0.16%. The scope of the tests carried out so far is: tensile test at + 20 ° C, 0 ° C, -20 ° C, impact test at temperatures: 20 ° C, 0 ° C, -20 ° C, -40 ° C, - 60 ° C and a fracture toughness test at temperatures of 20 ° C, 0 ° C, -20 ° C.
Dataset contains results of fracture toughness test (CMOD - force record, elastic compliance method) for 3 point bedn specimen. Test performed in accordance to ASTM E1820-18a standard.

title: The orthogonalization of simplified objects representing groups of buildings in Gdańsk district using the Simplify Building tool - scale 1:10000

description: The process of automatic generalization is one of the elements of spatial data preparation for the purpose of creating digital cartographic studies. The presented data include a part of the process of generalization of building groups obtained from the national geodesy and cartography resource from BDOT10k (10k topographic database) [1].
Data obtained from the Simplify Building tool activity (GDA_SimplificationArcGIS.geojason) are subjected to the next stage of the sequential generalization process - orthogonalization. This is a two-stage process:
- the segments with a similar azimuth are averaged (similarity within the epsilon in the angular extent) and the direction of the azimuth of each segment is compared and rotated according to the azimuth of the longest segment,
- from the longest part of the object's boundary, subsequent sections are rotated in relation to their own center so that a right angle is created.

title: Straightening of ship hull structure made of 316L stainless steel - microstructure of water cooled material

description: The AISI 316L type steel belongs to the group of chromium-nickel stainless steels. They are determined according to European standards as X2CrNiMo17-12-2 and belong to the group of austenitic stainless steels. Steels of this group are used for elements working in seawater environments, for installations in the chemical, paper, and food, industries, for architectural elements, and many others. The chemical composition of corrosion-resistant austenitic steels provides them with an austenite structure that is stable in a wide temperature range, under appropriate conditions for heating, soaking, and cooling. 316L steel plate was subjected to a technological treatment of hot straightening with an oxy-acetylene torch, which is not commonly used for this type of steel, mainly due to the lack of objective assessment of whether the austenitizing temperature has been achieved and the stability of the heat treatment process is ensured. The single-phase structure of austenite with high corrosion resistance, without precipitation of carbides, steel is obtained by supersaturation in water from 1100 °C. The purpose of the performed research was to determine the usefulness of the flame straightening process for a ship structure made of 316L steel. 
Eight test plates were provided for testing: two reference ones made of material not subjected to flame straightening (reference material), three straightened and naturally cooled ones), and three straightened and water-cooled ones. All panels had dimensions of 300×450 mm and a thickness of 10 mm. Straightening was carried out using triple flame burners. The straightening direction was perpendicular to the rolling direction.
This dataset contains photographic documentation of microstructure for water cooled material.
