title: Tropospheric delays derived from GNSS observations during the derecho event in Poland of 11th August 2017

description: Propagation of global navigation satellite systems (GNSS) radio signals is disturbed by the current state of the Earth's atmosphere. For this reason, advances processing of GNSS signals can be used for investigation of the atmospheric condition. In case of troposphere, the GNSS signals allow for obtain information of tropospheric delay, which is mainly expressed in zenith direction (zenith tropospheric delay, ZTD). ZTD parameter reflects the temporary state of the troposphere, while its variability reflects weather changes. For this reason, we can refer to GNSS meteorology. 
This dataset contains ZTDs estimated during the severe weather event of derecho in Poland on 11th August 2017. Calculations were conducted based on 30-seconds GPS/GLONASS observations derived from the 278 GNSS stations located in Poland. They belong to the three reference networks - national ASG-EUPOS and two commercial: TPI NETpro and VRSNet.pl. All calculations were performed using Bernese GNSS Software version 5.2 and precise point positioning (PPP) method. The a priori zenith hydrostatic delays model were taken from Vienna Mapping Function 1 (VMF1), whereas the wet delays were estimated every 5 min using the VMF1 wet mapping function. The tropospheric gradients were estimated with a 15-minute interval based on the Chen & Herring gradient mapping function. The a priori relative constraints equal to 2 mm for tropospheric delays and 0.2 mm for gradients were applied. The ionospheric free linear combination was used for elimination of first order delay of the ionosphere. The second and third order were also modelled. All observations below the 5-degree elevation angle were excluded. The IGS14 type mean antenna models were used. Estimated ZTDs and tropospheric gradients with a 5 and 15-minute intervals, respectively, are stored in separate TRP (native Bernese GNSS Software format) files for each station.

title: Nutrients, oxygen and suspended matter - Gdansk Deep (2001-2005)

description: The results show short-term changes in the concentration of nutrients (nitrates, nitrites, ammonium ions, phosphates and total forms of nitrogen and phosphorus), dissolved oxygen and suspended particulate matter - SPM and its main components (organic carbon - POC, nitrogen - PON, phosphorus - TPP) in the water column of the Gdańsk Deep (Gdańsk Bay).
The research was carried out in spring (2001, 2003, 2005) and in autumn (2004).
The water samples were collected from the water column with a rosette sampler (Ocean Test Equipment Inc.) and measurements of temperature, conductivity and depth were made with a CTD profiler (Falmouth Scientific Inc.).
Total and dissolved forms of nutrients were analysed using standard colorimetric methods. Oxygen dissolved in seawater was determined by the Winkler titration. SPM was determined by weighing filters dried to constant weight after filtration. The POC and PON analyses were performed on a CHNS/O 2400 Perkin Elmer analyser.
Changes of the concentrations of dissolved nutrients and their total forms in the water column of the Gdańsk Deep had a typical pattern. Surface layer (0-30m) was characterised by low concentrations of analysed compounds, where the average values for individual research periods did not exceed 0.45 µmol NO3- dm-3, 0.17 µmol NO2- dm-3, 1.27 µmol NH4+ dm-3, 38.62 µmol Ntot dm-3, 0.45 µmol PO43- dm-3 and 1.35  µmol Ptot dm-3. Below 30 m depth there was a gradual increase in the value and variability of concentrations of these substances. The maximum concentrations concerned the bottom layer (from 90 m in depth) where it was recorded 16.28 µmol NO3- dm-3, 0.98 µmol NO2- dm-3, 21.76 µmol NH4+ dm-3, 104.51 µmol Ntot dm-3, 9.59 µmol PO43- dm-3 and  15.10 µmol Ptot dm-3. Maximum concentrations in bottom waters were recorded in autumn (2004).
In the analysed period, the concentration of dissolved oxygen in the waters of the Gdańsk Deep ranged from 11.12 cm3 dm-3 in the euphotic layer to 0.00 cm3 dm-3 in the water above the bottom. The high dissolved oxygen concentration typically observed to a depth of 50 m. Below there was a sharp drop to the minimum concentrations. The lowest average oxygen concentration 0.50 cm3 dm-3 was recorded at the turn of September and October 2004.
In the case of POC, PON and TPP, the highest values were recorded in the 15 m surface layer (0.69, 0.09 mg dm-3 and 8.95 µg dm-3 respectively). Below there was a gradual decrease in the concentration of POC, PON and TPP, and the lowest results (mean 0.37 mg POC dm-3, 0.04 mg PON dm-3 and 4.30 µg TPP dm-3) concerned the 50-90m layer. A further increase in the concentration of suspended carbon, nitrogen and phosphorus was noted in the bottom layer (up to 0.52, 0.07 mg dm-3 and 8.44 µg dm-3 on average, respectively).

title: A novel method for drop in drop edible oils encapsulation with chitosan using a coaxial technique

description: The dataset present a novel one step method for oil encapsulation. In this coaxial system the oil constitutes the core of the capsule, while the chitosan solution is the polymer shell surrounding the core to provide separation of the core from the external environment. In comparison to other encapsulation methods, the presented technique is much simpler and can be performed under mild conditions. Moreover, the use of natural polymers as a coating matrix enables the use of the described technique in many branches of industry. The results were shown in the film.

title: The Chow Ring of flag manifolds

description: Schubert calculus is the intersection theory of 19th century. Justifying this calculus is the content of the 15th problem of Hilbert. In the course to establish the foundation of algebraic geometry, Van der Vaerden and A. Weil attributed the problem to the determination of the chow ring of flag manifolds G/P, where G is a compact Lie group and P is a parabolic subgroup. This problem has been solved by Borel for the classical Lie groups, and by Duan and Zhao for all compact Lie groups see [H. Duan, Xuezhi Zhao, On Schubert's Problem of Characteristics, to appear in Springer proceedings in Mathematics & Statistics, arXiv:1912.10745].
This databset is created to record the preliminary data to formulate the Chow rings of the flag manifolds associated to the exceptional Lie groups G=G2, F4, E6, E7, which are generated by a general algorithm (i.e. applicable to all flag manifolds) illustrated in the paper of Duan and Zhao mentioned above.
Each filename begins with the name an exceptional Lie group G, followed by an integer k, indicating that P is the parabolic subgroup of G corresponding to the k-th root. Each file has two part: two lists in the format of Mathematica. In the first part of each file we present the Schubert cells on G/P in term of its minimal word representation in the set W(P;G) of left cosets of the Weyl group of G by the Weyl group of P, where s(i,j) denotes the j-th Schubert cell of dimension 2i, and all of them form an additive basis of the Chow ring of G/P. In the second part of each file, we list all the L-R coefficients, a(i,j,k), required to express the product s(1,1) s(i,j) as a linear combination in the Schubert basis, that is s(1,1) s(i,j) = a(i,j,1) s(i+1,1) + a(i,j,2) s(i+1,2)+.... .

title: Data obtained by computation for X-ray focusing using oriented Gaussian beams

description: The propagation of X-ray waves through an optical system consisting of several X-ray refractive lenses is considered. Gaussian beams are exact solutions of the paraxial equation. The Helmholtz equation describes the propagation of a monochromatic electromagnetic wave. Since the widths of the beams are much larger than the wavelength of X-rays, Gaussian beams can also be regarded as nearly exact solutions to the Helmholtz equation. In this approach, the propagating wave is represented as a superposition of the oriented Gaussian beams. The direction of wave propagation in each Gaussian beam is consistent with the local propagation direction of the X-ray wavefront.
 The data show the result of computation of the X-ray intensity obtained near the focal point, while X-rays are focused by 4 parabolic lenses made of beryllium. In total, the data consists of 39403 points. Each point consists of 3 numbers, which are separated by commas. The first and second numbers are responsible for the position (in millimeters) of the point on the plane, the third number - for the intensity values. Points are separated by brackets and enters.
 The  algorithm for computing the dataset is available in the paper: P. Wojda, S. Kshevetskii,  Oriented Gaussian beams for high-accuracy computation with accuracy control of X-ray propagation through a multi-lens system, J. Synchrotron Rad. (2019). 26,  363-372, https://doi.org/10.1107/S1600577518017368.
