Reduced real lifetime of PV panels – Economic consequences

The maintenance and analyzing failures of PV systems and plants are becoming more and more important issues. Our data from the long-term operation of 85 photovoltaic power plants in central Europe show that their actual lifetime is about half that of the originally planned lifetime. After about 10 years, serious failures of 1st tier (bankable) PV panels occur at an increasing rate. This article presents selected typical data and describes the most serious failures. Furthermore, economic calculations of returns on investment are carried out in relation to the price of electricity, which is currently changing at a rapid pace. It shows that the PV panel lifetime reduction from 20 to 30 years, declared at commercial leaflets, to real lifetime about 10–12 years can reduce PV power plant profit substantially, but the investment is still worth it. The reason is that after 10–12 years ser vice/maintenance expenses to replace damaged PV panels and inverters are growing very quickly. The new information could be helpful for owners of PV power plants to get a more realistic estimation of profits

Geopolitical risks for Egypt wheat supply and trade

IntroductionSince 2005, Russia has established a stable position in Egypt's wheat imports, and after 2016, it became the largest global wheat exporter. The shift in Russian grain production has visibly affected wheat export destinations in favor of developing countries. This paper identifies the main determinants of wheat trade in Egypt concerning the primary risks associated with the war in Ukraine.MethodsThe paper utilizes time series analysis, index analysis, and an econometric model to define the statistical relationship between the quantity of wheat imported into Egypt and population development, wheat price, and wheat production.ResultsDespite increasing wheat production growth rates (1.9% p.a. over 2000–2020) and a growing population (2.01% p.a.), Egypt is unable to reduce its import dependence below 50% of total consumption. Undernourishment in Egypt remains at 5.2%–5.4% of the population. The econometric model shows that variables describing the evolution of production, population, and prices are statistically significant in relation to wheat imports. Egypt's wheat imports continue to increase even with rising prices, which is typical for developing countries. The war in Ukraine and associated commodity price increases have far-reaching implications for Africa's food security and supply systems.DiscussionEgypt's vulnerability to external influences, such as climate change, migration, rising commodity prices, and population growth, exacerbates the situation. Most African countries, including Egypt, struggle with the economic and social impacts of the COVID-19 pandemic. They also face rising food and energy prices, conflicts between the world's largest food producers, and increasing poverty rates. The research findings confirm that Egypt is among the highly vulnerable countries due to the war in Ukraine and the disruption of agricultural supply chains

Sect in a modern society and their influence on pupils (schools options in the field of protecting pupils from the influence of sects)

This doctoral thesis deals with the topic "Sects in a modern society and their influence on pupils" (school's options in the field of protecting pupils from the influence of sects). The main aim of the dissertation thesis is to map the sect issue and first of all the options of protection from their negative influences. To reach this aim, partial goals were set, which form the content structure of the thesis. The thesis is divided into five chapters. The first two should theoretically support the experimental part of the thesis, in which a pedagogical research in form of questionnaires at elementary and grammar schools was done. The questionnaires were focused on the knowledge of pupils and students about sects, their awareness and on finding out the real range of education about sects. Contribution of the thesis itself, elaborated in the remaining chapters, lies in the evaluation of mutual relation and intersection of official and practical educational materials, assessment of the research on pupils' knowledge of the sect issue, assessment of the approach to protection of pupils and in a proposal of a new educational model for protecting pupils from the influences of sects, applicable in educational practices
