title: Experimental studies of the load bearing capacity and stiffness of joint of aluminum temporary structures

description: The aim of the research activity was to analyze the behavior of an aluminum joint under the influence of various forms of loading. The joint was loaded separately with: normal force (Nx), shear force in the horizontal (Vy) and vertical plane (Vz), torsion moment (Mx) and bending moment in the horizontal (Mz) and vertical plane (My). For each form of load, the tests were performed on 5 samples. The connection in the analyzed temporary structure is achieved by driving a wedge into the hole of the rosette welded to the vertical pipe. In the study of each form of load, 3 levels of driving the wedge into the rosette hole were taken into account. In order to carry out the tests, a grip handle was designed and made to load the joint in a standard testing machine. Additional station was designed and built to obtain a repeatable level of driving the wedge. As a results of the tests, force-displacement relationships were obtained, taking into account the parameter of the wedge insertion depth. On the basis of the results permissible load values and the stiffness of the joint were determined. The forms of failure obtained as a result of individual actions allowed the identification of the critical areas of the joint. Additionally, as part of the scientific activity, tests of the strength properties of the materials of individual components of joint: pipes, wedges, rosettes and ledger end were carried out. Each of the listed elements has different strength properties. Material samples of individual elements were cut directly from the joints. Experimental tests were carried out on a standard testing machine with the use of strain gauge measurement.The data deposited in the repository were compressed into 10 folders in *.zip format. In 6 folders (Mx, My, Mz, Nx, Vy, Vz, ) there are files saved in *.csv, *.xlsx, *.jpeg formats relate to the obtained force-displacement or moment-rotation curves as well as photos from the performed tests of the joint. In 4 folders (Glowica_Ledger_end, Klin_Wedge, Rura_Pipe, Talerzyk_Rosette) there are files saved in *.csv, *.xlsx, *.jpeg formats regarding the results of material tests along with photos of samples.

title: Research data for the publication 'Nematic-to-isotropic phase transition in poly(L-Lactide) with addition of cyclodextrin during abiotic degradation study'

description: Research data for publication funded by the GREEN-MAP project. Includes macro images, GPC, DSC, X-ray, POM and AFM analyzes. The paper presents research on the liquid crystal (LC) properties of plain poly(L-lactide) (PLLA) and a physical mixture – composite – PLA with monodisperse sequence of methylated β-cyclodextrin (RM-β-CD) which was prepared with the use of a press, in order to develop a comprehensive characterization of (bio)degradable polyesters obtained under pressure. By introducing RM-β-CD into the polymer matrix, it is possible to obtain a chiral nematic mesophase during pressing, regardless of temperature and time. The obtained PLLA films exhibiting LC properties were subjected to degradation tests and the influence of degradation on these properties was determined. The degradation process demonstrated that colored planar texture of the chiral nematic mesophase, which was not observed prior to degradation in films without the addition of RM-β-CD, appeared after incubation in water as a result of the entrapment of degradation products in the polymer matrix. These unusual tailor-made properties, obtained in (bio)degradable polymers with LC properties using a simple method, demonstrate the potential for photonic applications.

title: Research data for the publication 'Cyclodextrin-oligocaprolactone derivatives – Synthesis and advanced structural characterization by MALDI mass spectrometry'

description: β-Cyclodextrin's involvement in the synthesis and characterization of new β-cyclodextrin-oligocaprolactone (βCDεCL) products obtained via the organo-catalyzed ring-opening of ε-caprolactone has been investigated. The approach consisted of solution polymerization (dimethyl sulfoxide and dimethylformamide) to obtain homogeneous βCDεCL derivatives. Oligomerization kinetics, performed by a MALDI MS optimized method in tandem with 1H NMR, revealed that monomer conversion occurs in two stages: first, the monomer is rapidly attached to the secondary OH groups of β-cyclodextrin and, secondly, the monomer conversion is slower with attachment to the primary OH groups. Further studies of MALDI MS was employed for the measurement of the ring-opening kinetics to establish the influence of the solvents as well as the effect of organocatalysts (4-dimethylaminopyridine and (-)-sparteine). Additionally, the mass spectrometry structural evaluation was further enhanced by fragmentation studies which confirmed the attachment of oligoesters to the cyclodextrin and the cleavage of dimethylformamide amide bonds during the ring-opening process.

title: Research data for the publication 'Susceptibility to degradation in soil of branched polyesterurethane blends with polylactide and starch'

description: Research data for publication funded by the GREEN-MAP project. A new branched polyesterurethane (PUR) based on poly([R,S]-3-hydroxybutyrate) (R,S-PHB) modified with poly([D,L]-lactide) (PLA) and starch was ynthesized and tested for the susceptibility to degradation in anthropological soil. Mass loss of samples and changes in surface morphology (SEM, optical microscope, and contact angle system) with simultaneously only slight changes in molecular weight (GPC), chemical structure (FTIR and 1HNMR) and thermal properties (DSC) indicate that these materials are subject of enzymatic degradation caused by the presence of microorganisms in anthropological soil. Chemical modification of branched polyesterurethanes with R,S-PHB and their physical blending with small amounts of PLA and starch resulted in a slow but progressive degradation of the samples. The study of susceptibility to degradation was carried out by burying the samples in the anthropological soil in conditions simulating the average moisture and temperature in Poland in the months from April to October. This experiment allows to predict the behavior of the investigated polymer samples after their disposal, outside the landfill, in the environment.

title: Irregular oscillations and symmetry breaking in a ring of coupled cells with yeast extract

description: Manuscript and open dataset for the manuscript.Abstract:Our work is focused on finding discrete non-uniform stationary states applicable for chemical computing and oscillations in a ring of coupled cells with glycolytic oscillatory reaction and equal transport rates for all chemical species. The cells (cuvettes) are fed by the Select Yeast Extract Y1625 and D-glucose solution, both enhanced by NaHCO3. The ring of coupled cells is formed by the two cuvettes and two capillaries. The mutual mass exchange is realized via reciprocal peristaltic pumping. The dynamic states of both cuvettes are measured by UV-Vis spectrophotometers at absorbance level of NADH (340 nm). We report an observation of in-phase, anti-phase, and phase-shifted glycolytic oscillations and transitions between uniform oscillations and chimera-like states occurring from an in-phase oscillatory system.We also performed an analysis of stability and bifurcations of stationary states in a model of twenty coupled cells in a cyclic array using the core model of glycolysis. Cells 1 and 11 represent main flow reactors (CSTRs) in the model with a much higher volume than cells 2-10 and 12-20, which approximate the capillaries mediating mass exchange between cells 1 and 11 as a cascade of small CSTRs. A bifurcation diagram in a plane of an inhibition rate coefficient (sigma_inh) and a transport rate coefficient (kd) is used to show the parameter region of occurrence of discrete non-uniform stationary states. We describe and mathematically simulate the mechanism of switching between them, establishing a chemical computing technique (working as AND/NOR logic gate). The ring of twenty coupled cells offers the same logic functions as two coupled cells.

title: Research data for the publication 'Bioactive (co)oligoesters as potential delivery systems of p-anisic acid for cosmetic purposes'

description: Research data for publication funded by the GREEN-MAP project. In preliminary studies, the activity of biodegradable polyester matrices containing conjugated bioactive compounds was verified. Bbioactive synthetic oligo(3-hydroxy-3-(4-methoxybenzoyloxymethyl)propionate) and oligo[(3-hydroxy-3-(4-methoxybenzoyloxymethyl)-propionate)-co-(3-hydroxybutyrate)] were obtained via anionic ring-opening oligomerization. Molecular weight of the bioactive PHBV films before and after use, measured by GPC. In vitro cytotoxicity studies showed that the synthesized bioactive polyesters were non-toxic and well tolerated by the tested cells. The application of ESI-MS spectrometry to characterize aqua-soluble hydrolytic degradation products of bioactive polyesters allowed to determine their molecular level chemical structure and helped to confirm that the system developed release bioactive compound.

title: Research data for the publication 'Surface modification of PHBV fibrous scaffold via lithium borohydride reduction'

description: Lithium borohydride (LiBH4) reduction was used to modify the surface chemistry of PHBV fibers obtained by electrospinning. The use of LiBH4 allowed the formation of surface hydroxyl groups under very mild conditions, which was crucial for maintaining the fibers’ integrity. The presence of these groups resulted in a noticeable improvement in the surface hydrophilicity of PHBV, as revealed by contact angle measurements. After the treatment with a LiBH4 solution, the electrospun PHBV fibrous mat had a significantly greater number of viable osteoblast-like cells (SaOS-2 cell line) than the untreated mat. Moreover, the results of the cell proliferation measurements correlated well with the observed cell morphology. The most flattened SaOS-2 cells were found on the surface that supported the best cell attachment. Most importantly, the results of the study indicated that the degree of surface modification could be controlled by changing the degradation time and concentration of the borohydride solution.

title: Age- and lifespan-dependent differences in GO caused DNA damage in Acheta domesticus

description: Article title: Age- and lifespan-dependent differences in GO caused DNA damage in Acheta domesticus.Abstract: The rising applicability of graphene oxide (GO) should be preceded by detailed tests confirming its safety and no toxicity. Sensitivity to GO of immature or with different survival strategies individuals has not been studied so far. Therefore, in the present research, we focused on the GO genotoxic effects, examining selected parameters of DNA damage (Total DNA damage, double-strand breaks - DSB, 8-hydroxy-2 '-deoxyguanosine - 8-OHdG, abasic site - AP sites), DNA damage response parameters, and global methylation in the model organism Acheta domesticus. Special attention was paid to various life stages and lifespans, using wild (H) and selected for longevity (D) strains. DNA damage was significantly affected by stage and/or strain and GO exposure. Larvae and young imago were generally more sensitive than adults, revealing more severe DNA damage. Especially in the earlier life stages, the D strain reacted more intensely/inversely than the H strain. In contrast, DNA damage response parameters were not significantly related to stage and/or strain and GO exposure. Stage-dependent DNA damage, especially DSB and 8-OHdG, with the simultaneous lack or subtle activation of DNA damage response parameters, may result from the general life strategy of insects. Predominantly fast-living and fast-breeding organisms can minimize energy-demanding repair mechanisms. The article is written within the project "Modern nanoparticle and model organism - a toxic relation? Physiological and cellular causes of developmental disorders in Acheta domesticus after oral exposure to graphene oxide"The main goal of this project is elucidation and description of mechanisms of decreased survival and decreased DNA stability after constant (five subsequent generations) exposure of cricket cohorts (Acheta domesticus -model organism) to sublethal amounts of GO in their food, and also evaluation of physiological and biochemical symptoms of adjustment to such stressful condition.The partgoals of this project are to check and describe:1. connections between exposure of A. domesticus to GO and composition of gut microbiota and, in turn, their physiology (growth, reproduction and general fitness);2. microbiomes composition in GO-exposed crickets in relation to strain and generation;3. microbiome metabolic profiles in GO-exposed crick -dependent scheme;4. energy budget indices in both strains of GO-exposed crickets in relation to exposure time; digestive enzymes activity;5. general cell state in GO-exposed crickets in relation to strain and exposure time;6. effects of GO on telomere length, telomerase activity, DNA methylation and DNA damage and repair level in successive generations of two house cricket strains

title: Effectiveness of friction force reduction under the influence of longitudinal tangential vibrations depending on the contact load in the normal direction

description: The dataset contains the results of experimental studies and numerical analyzes of the influence of normal pressures on the level of friction force reduction in the presence of longitudinal tangential vibrations, which were presented in the article entitled „The Influence of Normal Pressure on the Friction Force Reduction Effect Caused by Longitudinal Tangential Vibrations” published in Advances in Science and Technology Research Journal.The deposited data include, among others, the experimentally determined characteristics of the compliance of the steel-steel contact as a function of normal pressures for the contact with specified roughness. Based on these characteristics, the values of the tangent stiffness coefficient were determined, which are necessary to carry out numerical analyzes of influence of longitudinal tangential vibrations on the friction force using dynamic friction models, such as the Dahl model and elasto-plastic model.In experimental studies, the change of the drive force under the influence of longitudinal tangential vibrations was measured at certain values of normal pressures and the fixed amplitude and frequency of these vibrations. To assess the effectiveness of friction force reduction, a dimensionless value of coefficient calculated as the ratio of the drive force measured in the presence of longitudinal tangential vibrations, corresponding to the average friction force in one vibrations period, to the Coulomb friction force corresponding to the friction force without vibrations, was adopted.Data deposited in the repository was saved in *.mat, *.xlsx, *.jpg and *. pdf format.

title: Muscle-derived exophers promote reproductive fitness

description: Using Caenorhabditis elegans, we discovered that large extracellular vesicles (known as exophers) previously found to remove damaged subcellular elements in neurons and cardiomyocytes are released by body wall muscles (BWM) to support embryonic growth. Exopher formation (exopheresis) by BWM is sex-specific and a non-cell autonomous process regulated by developing embryos in the uterus. Embryo-derived factors induce the production of exophers that transport yolk proteins produced in the BWM and ultimately deliver them to newly formed oocytes. Consequently, the offspring of mothers with a high number of muscle-derived exophers grew faster. The deposited data were used to generate all the figures in the publication, including microscopic images, measurements of the amount of exopher in response to genetic modifications or measurements of animal motility.
