In the cases of water and water rich mixtures including biological systems, a GHz frequency relaxation process appearing at around 20GHz with the relaxation time of 8.2ps is generally observed at 25°C. The GHz frequency process can be explained as a rate process of exchanges in HB and the rate becomes higher with increasing HB density. In the present work, we analyzed the GHz frequency process and clarified physical meanings of the fractal nature of water structures in various aqueous systems. Dynamic behaviors of HBN were characterized by a combination of the average relaxation time and the distribution of the relaxation time. The fractal analysis offered an available approach to both solution and dispersion systems with characterization of the aggregation or dispersion state of water molecules. In the case of polymer-water mixtures, the HBN and polymer networks well penetrate each other. However, the HBN were segmented and isolated more by dispersed and aggregated particles in the case of dispersion systems. These HBN fragments were dominantly evaluated by smaller values of the fractal dimension obtained from the fractal analysis, but it is also related with other two parameters. The fractal analysis is now one of the most effective tools to understand molecular mechanism of HBN in aqueous complex materials including biological systems.","PeriodicalId":207294,"journal":{"name":"2018 12th International Conference on Electromagnetic Wave Interaction with Water and Moist Substances (ISEMA)","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133480852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The measurements were conducted using a vector network analyzer and an open-ended coaxial-line probe in the frequency range from 200 MHz to 20 GHz at 9±0.5ºC. The results showed that the real part of dielectric permittivity of the tested products decreased with an increase of frequency, while the imaginary part of dielectric permittivity increased below 14.3 GHz for yoghurt and 13.6 GHz for milks and decreased above those frequencies. During storage the real part of dielectric permittivity of yoghurt and milks slightly decreased. The value of the imaginary part of dielectric permittivity varied much more for milks during time storage. The changes of the imaginary part of dielectric permittivity of the tested products were associated with the changes of pH value. Finally, complex dielectric permittivity spectra of the measured products were modeled with the two-pole and three-pole Debye model. Three-pole Debye function was better fitting to the results.","PeriodicalId":207294,"journal":{"name":"2018 12th International Conference on Electromagnetic Wave Interaction with Water and Moist Substances (ISEMA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127306823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An innovative method of irrigation is analysed, consisting in high pressure injection of water to soil. Thanks to this, water can be supplied within a short time (1–3 seconds) at doses required for a single plant, e.g. from 300 to 700 ml. Water injection is performed by means of a mobile platform. Sensors of LP/ms (Labolatory Probe / moisture salinity) type were used for empirical determination of the initial condition in a mathematical model based on the Richards equation. That equation is usually used for the simulation of water flow in porous media. As it is a differential equation, its solution requires that an initial condition is given. In the case under consideration, that condition was the description of water state in the vicinity of the point of water injection. The state of soil water was determined with the help of sensors that allow continuous and basically non-invasive measurement of volumetric moisture. That value was converted, using a function type relation (pF curve), into the matric potential. This allowed the calculation of the total potential which is the value modelled in the predictive equation. It was demonstrated that the use of sensors of LP/ms type allows correct determination of the initial condition in the mathematical model describing water movement in soil irrigated with the injection method.","PeriodicalId":207294,"journal":{"name":"2018 12th International Conference on Electromagnetic Wave Interaction with Water and Moist Substances (ISEMA)","volume":"58 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116356218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
