QUASIANALYTICAL ESTIMATES OF INDUCTANCE USING SUBCONDUCTOR METHODS
Subconductor methods or partial wire methods yield reliable results for conductor parameters such as inductance, capacitance, conductance and resistance and can be used to estimate these parameters for conductor configurations involving complex geometries which cannot be handled using analytical methods. The values of inductances obtained using partial wire method are critically compared with values obtained using analytical methods
POWER2GAS IN THE AUTOMOTIVE INDUSTRY
Because of the climate change and new laws to reduce the carbon dioxide emission, the automotive industry has a major potential. With alternative actuations and new ways to make fuels accessible, like Power2Gas, it is possible to drive nearly CO2 neutral. This examination considers especial passenger cars and lorries in Germany in terms of costs, different fuels and emission exhaust
POWER2GAS IN GERMANY – TECHNOLOGY AND OPPORTUNITIES
For the future, Germany banks on renewable energy. That bears a challenge, because this energy generation heavily depends on climate conditions. Therefore, a proper storage technology is needed to ensure the energy supply all over the year. Furthermore, the expansion of renewable power plants and the power grid expansion advance in different pace. The power grid operators have to react with feed-in management actions to safe the grid against overloading. As a consequence, operators have to switch off some of their windmills if the wind blows to strong. Suitable storage technologies will help to avoid shutting down renewable power plants to generate the full energy potential. A promising technology is Power2Gas. These facilities transform electrical energy into gas, which could be stored in the huge German gas network

Journal of Clinical Education in Physical Therapy – the first year in review
One year ago, we launched the Journal of Clinical Education in Physical Therapy (JCEPT) with the twin aims of facilitating communication among all involved in physical therapy clinical education and developing educational scholarship related to clinical training. Since then we have leaned on our distinguished JCEPT editorial board, that represent a variety of clinical specialties and roles in physical therapy education, to continue to develop our website and the growing number of submitted manuscripts. In keeping with the mission, three papers have now been published: one perspective addresses the communication network among the many stakeholders in physical therapy clinical education; and two studies examine the integration of simulation into physical therapy curricula
Mechanical and electrical properties of the solid sapropel
In this paper are explored the mechanical (ultimate compression strength, ultimate strain, Young’s modulus, hardness) and the electrical (relative permittivity, specific electrical resistance, quality factor, their dependence on the electric field frequency in the range till 1MHz) properties of the solid sapropel. For the researches are used samples from the solid, monolith sapropel (obtained in the drying process) and samples from the sapropel powder that are pressed with a different force; before the measurements, a part of these samples were heated. There is explored the dependence of the relative permittivity on temperature. Are explored the methods for the forming of the products from the solid sapropel powder

Clinical education across the physical therapy professional continuum
The Journal of Clinical Education in Physical Therapy (JCEPT) is a peer-reviewed open-access journal that aims to develop and disseminate quality evidence related to clinical education in physical therapy. Over the first 3 years of publishing, the number of article downloads has increased quickly with 2021 downloads more than tripling the previous year. Two articles were downloaded over 200 times in just the last year. This year, JCEPT has been indexed by the Directory of Open Access Journals, and we are on track to meet our goal of PubMed Central indexing within our first 5 years.
COVID-19 continues to affect society and education. In this volume, two papers explore the impact of changes imposed on physical therapy education by the ongoing COVID-19 pandemic. Many programs had to make changes to their clinical education routines due to COVID-19 restrictions and sudden limitations in clinical placements. One article explored the effect of fewer preparatory integrated clinical experiences on interpersonal communication skills and confidence in the acute care setting. Another explored the financial impact of COVID-19 on doctor of physical therapy students.
JCEPT publishes scholarly work related to physical therapy education affecting any aspect of clinical practice at all levels of the professional continuum.1 The 2022 JCEPT volume, for instance, includes a model of physical therapist assistant learning in an intra-professional pro bono clinical environment with entry-level physical therapy students. For physical therapist education, articles address readiness for telehealth, the effect of integrated clinical experiences on interpersonal communication, decision making, and clinical reasoning. Post-professional topics include developing residents’ clinical reasoning and clinical instructors’ mentoring skills.
Physical therapy as a profession requires a commitment to lifelong learning to ensure the profession evolves to best serve the public purpose.2Â Lifelong learning is sometimes thought of as simply individual clinicians continually gaining additional knowledge and skill. Moving the profession forward, however, demands more structure.2Â A more detailed formulation of lifelong learning includes activities that demonstrate the voluntary participation in professional activities that expand learning and the pursuit of opportunities to develop professionally.3Â Examples within this volume include the pro bono clinics, residency training, and clinical instructors participating in simulated learning experiences within the didactic portion of physical therapy training. Advanced degrees and continuing education are also parts of the continuum for future volumes to explore.4
As the journal continues to grow, we expect to publish more papers on topics important to physical therapy clinical education in various forms. JCEPT accepts manuscript types such as original research, narrative and systematic reviews, innovative teaching methods or educational models, clinical education or clinical case reports, and critically appraised topics.

EFFECT OF HEAT TREATMENT ON ELECTRICAL AND MECHANICAL PROPERTIES OF THE SOLID SAPROPEL
In this work changes of electrical and mechanical properties (hardness) of the solid sapropel after its heat treatment were researched. Changes of real and imaginary parts of dielectric permittivity, dielectric losses and specific electrical resistance depending on electrical field frequency in the range 0.01Hz- 1MHz were observed. Temperature dependences of AC (at 1 kHz) and DC electrical conductivity were studied. Chemical sample composition, IR spectra and structure of the solid sapropel were investigated. Heat treatment has a noticeable effect on the electrical characteristics of solid sapropel due to the strong influence of water on the charge transfer in this complex material. Charge transfer occurs predominantly due to ion migration and demonstrates strong dependence upon hydration - dehydration processes. After the heat treatment of the solid sapropel at the temperature of 1000C its hardness doesn’t change. If the sample of the solid sapropel is subjected to 20 min heat treatment at the temperature of 1500C, its hardness decreases by 5.4%, the number of C=C bonds decreases by 6.3±0.1%, the number of C=N bonds decreases by 2.2±0.1%, the number of C-C bonds decreases by 1,7±0.1%, the number of C-H bonds increases by 18.5±0.3%. It shows that in the temperature range 100-1500C destructive processes of the solid sapropel start, although visually (with optical microscope and with SEM) changes of structure are impossible to observe yet
