. In connection with renewable energy sources, the courtyards of the buildings provide space for the installation of agrivoltaics for sustainable development. This paper proposes the use of courtyards of low-rise buildings for agrivoltaics. This will increase the area for installing photovoltaic systems, which have so far only been installed on roofs or facades or on open fields. The advanced design of the photovoltaic systems will enable the dual use of the area both for the cultivation of crops and for the production of electricity at the same time. The increased amount of electricity produced in photovoltaic systems also contributes to reducing the carbon footprint. On the courtyard as well as on the open fields, it is possible to grow agricultural crops between rows of photovoltaic panels. The partial shading of seedlings during summer sunny days reduces their heat stress and slows down soil drying. Solar eclipses are rare, but their impact on electricity generation is significant. We evaluated the measured data and we assessed the electricity production and the influence of a solar eclipse on the electricity production in photovoltaic power plants in the Czech Republic. The daily loss in production depends on the size of the eclipse. A comparison of the annual electricity production in two selected PV power plants with the expected values according to PVGIS testifies to the quality of the construction and the PV panels used in both power plants.

. The aim of this research is to determine how phenolic acids affect the individual structure of gluten proteins: gliadins and glutenins, by understanding the underlying molecular interactions. Fourier transform infrared spectroscopy was used to determine changes in the secondary structure of the individual gluten network proteins: gliadins and glutenins, after addition of selected phenolic acids to the model dough. Phenolic acids were added to the model dough at the following concentrations: 0.05, 0.1 and 0.2% (w/w). The phenolic acids induce changes in the secondary structure of the gliadins and glutenins. The degree of interaction depends on the structure and concentration of the added phenolic acid. In most cases, these interactions lead to the formation of disordered structures in both gliadins and glutenins. From the results obtained, it can be concluded that the inclusion of certain phenolic acids in the dough affects the hydrogen bonding in gliadins and glutenin, and that phenolic acids interact non-covalently with these gluten proteins. The findings could potentially be applied to food chemistry and may have an impact on the allergenic properties of gluten, particularly in relation to the reduction of the β-turn content within glutenins.

.This review is intended to contribute to the evidence of the effects of static magnetic field on cells and tissue, as well as to present research results that will elucidate the com - plex matters involved in the formation and remodeling of cells. The cell characteristics studied in the papers that are reviewed include cell viability and proliferation, aggregation and their dif - ferentiation, structure and membrane potential. A moderate static magnetic field in the most commonly used range of 2-80 mT has potential application in the formation and remodeling of plant and human cells. However, in the case of cancer cells, the range of fields commonly used was 0.2-9 T. Magnetism promotes changes in plant cell growth, which prompts the cell to proliferate, thereby ensuring an increased rate of biomass production. Some researches presented the enhancement of the differentiation of plant cells and skeletal muscle tissue by over 30% at 80 mT static magnetic field. Changes in the cell cycle and growth reflect directly on the cell number and viability and provide useful information to detect modifications in the cell machinery. Static magnetic field, depending on its intensity, enhances cell proliferation and thus may improve, among other processes, tissue regeneration, wound healing and the inhibition of cancer cell proliferation. Researchers showed, among other things, that cells under the influence of static magnetic field changed their shape, had a larger chloroplast, stiffer cell wall, density of the cytoskeleton and cytoplasm contained several mitochondria. Numerous studies also discussed the behavior of the cell membrane of plant and animal organisms, includ - ing humans, under the influence of an static magnetic field. The effects of static magnetic field on the cell membrane of plant and human cells were similar. The research results indicate that static magnetic fields can significantly change membrane depolarization and its potential that regulates ion movement and thus can have a significant impact on the properties and biological functionality of the cell. Studies have shown that continuous application of static magnetic field caused deformation and damage of cell membrane. Based on the theoretical analyses presented also in this review, it can be concluded that static magnetic field affects cells and tissue, giving them changes in properties and behaviors and modulates, e.g . in the activity of ion channels. Thus it may produce effects leading to changes in the functioning of the cell. It is possible to formulate directions for further research aimed at using static magnetic fields for the non-invasive remodeling and formation of plant and human cells.

. Soil moisture is a key parameter in determining crop growth and yield. Modern agriculture does not only take into account soil moisture measurements obtained once at selected points in the field, but also focuses on moisture monitoring. Knowledge of the variability over time and analysis of the variation in readings caused by heavy rainfall or strong sunshine and high soil temperature changes is very important for future modelling, prediction and automated irrigation. The aim of this paper is to present a developed soil moisture monitoring system for a soil profile up to 34 cm depth incorporating Internet of Things technologies. The system was built based on an eight-channel time domain reflectometer to measure soil moisture based on dielectric properties. The developed system integrates both dielectric moisture measurement and innovative web-based server and visualisation services. The autonomous station was equipped with a long-range wireless communication and a solar-charged battery. Analysis of the results enabled us to observe the subtle deviations of moisture content of the upper soil layer during diurnal cycles. The designed station can be used in the future to integrate a high accuracy automatic field irrigation system and acquire data for precision agriculture.

. In order to design a tomato stem crushing and bagging machine and also optimize its operational parameters, knowledge concerning the mechanical properties of harvest-ready tomato stems is required. The mechanical shear properties of the stems were studied by conducting a single-factor experiment, taking the blade angle, moisture content and sampling range as the experimental factors and the peak shear force as the evaluation indexes. The results showed that the blade angle had no significant effect on the mechanical shear properties of tomato stems, while the leaf water content and sampling location had significant effects on the mechanical shear properties of tomato stems. The largest peak force for cutting the tomato stem was observed in the middle of the sampling range, therefore a shear force greater than 411 N should be provided when designing the crushing device. At the same time, the machine should be used to harvest the tomato stalks as early as possible. The study will provide the necessary experimental data and theoretical basis for the development of an optimized tomato stem crushing and bagging machine.
