“…The reactions of microorganisms to light may include the release of various substances, including plant growth regulators. It is known that light can have a great influence on the development of both beneficial and neutral and pathogenic microflora [41,97,102,103]. On the one hand, light can have a direct effect on the microflora [104][105][106][107][108][109][110].…”

“…Despite all their advantages, such phosphors have a significant drawback: they lose their effectiveness very quickly due to light burnout [37]. Another type of phosphor that is gaining more popularity is nanosized metal-containing phosphors [33,38,39], among which luminescent nanoparticles based on rare earth metals occupy a special place [34,[40][41][42][43][44][45]. A relatively widely used rare earth metal in the production of phosphors is europium (Eu).…”

Two Types of Europium-Based Photoconversion Covers for Greenhouse Farming with Different Effects on Plants

et al. 2023

In the present work, we investigated the effect of light conversion using europium (Eu(III))-based photoconversion covers on the cultivation of agricultural plants and their resistance to stress conditions. Two types of europium nanoparticles were used. The first one was obtained from europium oxide (Eu2O3) by laser fragmentation. The second one was Eu3+:LaF3 nanocrystals obtained by hydrothermal-microwave treatment, the content of europium ions in which was 50% of the total amount of cations. Tomatoes (Solanum lycopersicum) and cucumbers (Cucumis sativus) were used as model plants. It was shown that plants grown under cover with Eu2O3 (PCC-Eu2O3) were 30–40% larger, gave a higher yield, and the activation of gas exchange processes and the light phase of photosynthesis in the leaves in response to the lighting was faster. On the contrary, plants grown under cover with Eu3+:LaF3 (PCC-Eu3+:LaF3) tended to slow down the rate of biomass accumulation and decrease the rate of gas exchange activation. It was shown that photoconversion covers change the resistance of plants to stress conditions: if plants grown under PCC-Eu2O3 became more sensitive to heat (+40 °C) and cold (+4 °C) treatment, then plants grown under PCC-Eu3+:LaF3 became more resistant to high and low temperatures. It was found that PCC-Eu2O3 inhibited the development of the phytopathogen Phytophthora infestans on tomato plants. It was assumed that changes in the illumination spectrum by the photoconversion covers cause both the activation of plant growth in the case of Eu2O3 and an increase in plant resistance in the case of Eu3+:LaF3 applications.

“…The third approach is to convert a light of a certain part of the spectrum into either electrical [65][66][67][68] or thermal [69] energy, which can be used for the needs of the greenhouse itself. A decrease in the sunlight intensity and conversion of light can be achieved using photoselective and photoconversion covers, respectively [23,43,44,46,[48][49][50][51][52]70,71]. Photoselective covers contain dyes that reduce the intensity of a certain part of the solar spectrum.…”

“…Photoselective covers completely or partially absorb photons of a certain wavelength [43][44][45][46][47], while photoconversion covers convert photons of one wavelength into photons of another wavelength using luminophores. In agriculture, luminophores, which convert high-energy photons into low-energy photons, are most widely used [48][49][50][51][52]. In addition, up-conversion covers containing luminophores are capable of emitting photons with higher energy than those used for excitation, and are currently being developed [53].…”

Current Approaches to Light Conversion for Controlled Environment Agricultural Applications: A Review

2022

Modern agriculture cannot be imagined without the introduction of smart and efficient technologies. These, undoubtedly, include technologies for directed regulation of the illumination of agricultural plants. Depending on the climatic conditions of cultivation, farmers shade or additionally illuminate the plants, and also change the spectrum of the light reaching the plants. The aim of this review is to provide an overview of solar light conversion methods and approaches for agricultural applications and discuss their advantages and limitations.

“…One final distinction to mention are several related fields of study that I have not had space here to probe, namely, "Christian Philosophy" (see work through The Davenant Institute, e.g., Minich 2018), "Jewish Philosophical Theology" (Frank, Leaman, and Manekin 2000), "philosophical hermeneutics" (Pokorny and Roskovec 2002), and a large portion of Christian "philosophical theology" that may not employ scripture at all or do so ad hoc. The history of philosophical engagement with the Bible may also begin to attract more attention as these works continue to emerge and receive scrutiny (see del Prete,…”

Philosophical Engagement With the Hebrew Bible/Old Testament: Some Methodological Reflections

Currents in Biblical Research

A raft of recent “philosophical” interpretations have emerged within biblical studies. They have in common the expectation that ideas from the discipline of philosophy will be helpful for understanding the biblical texts. However, the way in which they engage the two varies, and it is their methods that are teased out in this article. I offer a simple trajectory of approaches for works in this area, marked by two ends of characteristic disciplinary habits: using the Hebrew Bible/Old Testament for philosophical reflection and using philosophy for biblical interpretation. In this, the article sketches a much-needed research profile for a lively subdiscipline.
