title: Place identity in socialist-modernist building

description: The data include 96 individual response of falowiec's residents on the following  scales (1) social identification, (2) falowiec’s place identity (3) interest in history of place. Each line represents responses obtained from one participant and his or her demographic characteristics. like gender, age, and education level. 
Ident1-12 – identification with residents of Gdańsk. Polish version of a 3-factor group identification scale proposed by Cameron (2004; see Bilewicz & Wójcik, 2010, for its previous use in Poland). It contained 12 items (e.g., ‘I have a lot in common with other people living in Gdańsk’ and ‘I often regret that I am a Gdańsk inhabitant’). Participants responded on a 7-point scale ranging from (1) strongly disagree to (7) strongly agree.
PI_fal 1-3 -   Falowiec’s place identity. To determine how identity is shaped by being a resident of the falowiec, participants were asked to indicate, on a 3-item scale, how being a resident of the falowiec is important to who they are and how they feel. Respondents answered in a 7-point response format.
IHF 1-5  - Interest in history of  falowiec . The scale developed by Lewicka (2012) was adapted to take into account the context of the building instead of the city of residence (e.g., ‘I'm interested in the history of the falowiec; I have books at home on the history of the falowiec; I like to visit websites or fan pages devoted to the history of the falowiec.’). Respondents answered in a 7-point response format.
lor_fal = length of residence in falowiec (in years)
lor_gdn= length of residence in Gdańsk (in years)
ident_agg = aggregated data on identification scale (ident1-12)
IHF_agg = aggregated data on interest in history of falowiec scale (IHF1-5)
PI_fal_agg = aggregated data on falowiec’s place identity scale (PI_fal 1-3)

title: Evaluation of antimicrobial activity of porous composites based on chitosan/poly (vinyl alcohol)

description: The dataset contains the results of microbiological tests of composite porous materials whose activity was assessed for their ability to reduce the number of Escherichia coli and Staphylococcus aureus strain, representing the Gram (-) and Gram (+) bacteria, respectively.
The evaluation of antimicrobial properties of filaments was made according to the quantitative ASTM E2149 method with slight modification. Colonies of bacteria were first subcultured on triptic soya broth agar plates and incubated for 24 h at 37 °C. Microbial suspensions were prepared in test medium by adjusting the number of bacterial cells between 1.5 x 107 ÷ 5.0 x 107 CFU/mL with spectrophotometer by measuring the absorbance at 600 nm wavelengths (optical density 0.1). Squares with a side of 4 cm were cut from the composites and sterilized with UV radiation (30 minutes on each side). Composites were exposed to test organisms on separate dishes by spreading 0.4 mL of prepared inoculum across the surface of the sample. Immediately after inoculation (time 0) and after 24 h incubation (37 °C), samples were placed in 10 mL of PBS and vortexed intensively for 25 s. Next ten-fold serial dilutions were plated on TSA plates and incubated for 24 h at 37 °C. After the incubation, only plates where 30 CFU to 300 CFU were counted. When no colonies were recovered the number was recorded as “10” and the number of viable counts was established (CFU/mL). The concentration of bacteria was obtained by following formula:
Vc = N x D,
where Vc is the bacteria concentration, in colony forming units per mL (CFU/mL), N is the average value, in colony forming units (CFU) from Petri dishes, and D is the dilution factor from the plates counted. Antimicrobial activity on a logarithmic scale was calculated according to the formula:
R = log (B/A)
where A is the average of the number of viable cells on the test sample after 24 h incubation at 37 °C (CFU/mL) and B is the average of the number of viable cells on the control sample after 24 h incubation at 37 °C (CFU/mL).
The obtained results of chitosan/poly (vinyl alcohol) composites with a mass proportion of 1: 1 indicated the antimicrobial effect of materials and a reduction in the number of microorganisms by more than 2 logarithmic orders of magnitude of both tested strains (figures- the pictures of filament fragments were taken with a Nikon D7200 camera).

title: The electromagnetic field intensity in industrial buildings

description: The dataset contains the results of measurements of electromagnetic fields, separately electric and magnetic, carried out at selected places in the building of an operating industrial enterprise.
Due to the measurements, sources of the strong magnetic fields were located in the low-frequency range. Based on the analysis of the measurement results, a few recommendations were made to reduce the level of magnetic intensity in some particular places.
Electromagnetic field measurements were carried out in the laboratory rooms of the production building, adapted for installation of measuring and control instrumentations (rooms from 1 to 11). These rooms are situated on the ground floor of the building – under electric hardening furnaces. In the place near the hardening furnaces there are complex wiring systems of great power emitting the intensive electromagnetic field.
The measurements were performed during the production shift with the use of the ESM-100 H/E field meter of Maschek. This isotropic meter of the electromagnetic field enables measurements of both the electric field component and the magnetic component within the range from 5 Hz to 400 kHz in four successive measurement subranges: from 5 Hz to 400 kHz (-3dB limit), at frequency 50 Hz (for 12 dB of the band-pass filter), in the band from 5 Hz to 2 kHz and from 2 kHz to 400 kHz. In each measurement subrange, the meter provides the measurements of the field intensity in the range: from 1 nT to 20 mT for the magnetic field and from 0.1 V/m to 100 kV/m for the electric field. The values of H (magnetic) and E (electric) fields are displayed simultaneously in three-dimensional values. All measurements were carried out on the height of 0.8 ±0.1 m from the surface floor. The location of individual measuring points is shown in Figure.  Sketch of the ground floor of the building together with the numbering of the rooms and measurement points

title: Cyanobacterial occurence in the Kociewskie lakes (2004)

description: This dataset includes information about the cyanobacterial occurrence in 3 lakes in the region Kociewie (northern Poland), in 2004. Presented data concern basic physicochemical and biological parameters of sampled waters (temperature, pH, Chl a), the occurence of potentially toxic cyanobacterial species, and the type and concentration of toxins (microcystin) detected in the collected water samples. The obtained results sho that in Kociewskie lakes cyanobacterial blooms are most formed by species belonging to Microcystis and Dolichospermum genera. In each lake microcystin-RR and -Lr were found. The highest concentrations of microcystin-RR were recorded in Kałębie Lake. Additionally, there is no clear correlation between the abundance of potentially toxic or toxic cyanobacteria and the concentration of toxins in phytoplankton samples.

title: Ocean mixed layer dynamics: high-resolution simulations of wind, wave and convective effects

description: This dataset contains results of high-resolution numerical simulations of the ocean mixed layer (OML) forced by wind, waves and cooling from the atmosphere, i.e., under strongly turbulent, convective conditions. The goal is to provide detailed, three-dimensional information about OML circulation, turbulent kinetic energy, and temperature and salinity variations under conditions that are typical e.g. for Arctic and Antarctic polynyas. Understanding those water bodies is crucial for both regional and global ocean and climate models, and the description of OML dynamics there is a prerequisite for developing models of sea ice formation and ocean convection under strongly turbulent conditions.
The simulations were performed with a state-of-the-art, open-source hydrodynamic model CROCO (http://www.croco-ocean.org/), modified and configured to make it suitable for the present study. The model domain covers surface area of 1200m*1200m (with horizontal resolution of 3m and periodic lateral boundaries) and is 150m thick (with 60 vertical levels of variable thickness, ranging from 9m at the bottom to 0.5m at the top. A nonhydrostatic, non-Boussinesq version of the model is used (permitting high vertical velocities related to convective plumes), with wave-induced currents (Stokes drift), forced by heat and momentum fluxes from the atmosphere. The model correctly reproduces the Ekman circulation in the OML
The model is run for a range of wind speeds (from 5 to 30 m/s) and air-water temperature differences (from -20 to 0degrC). Deep water wind waves are assumed (i.e., no presence of swell), with parameters (significant wave height, peak period) computed from the wind speed. The mixed layer depth equals 100m, a value which is representative for many polar polynyas. Each individual simulation is initialized with a horizontally uniform, analytical Ekman-Stokes solution corresponding to a given wind/waves forcing, and continued for 18 hours. The results are saved every 1 hour in the form of:
 
Area-averaged values of surface heat and momentum fluxes
Area-averaged vertical profiles of the current velocity components, turbulent kinetic energy, water temperature, salinity and density (and their standard deviation)
Three-dimensional fields of the variables listed above at two selected time instances, 12 and 18 hours after initialization.
