A Study on Long-Term Operation and Performance Loss Rates of Various PV Technologies in Eastern Poland
No full textDespite Poland’s rapid PV deployment, long-term system performance studies are virtually nonexistent. This paper analyzes the four-year performance of four small PV systems in Bordziłówka, eastern Poland, each using a different technology: polycrystalline silicon (pc-Si), amorphous silicon (a-Si), cadmium telluride (CdTe), and copper indium gallium selenide (CIGS). The analysis focuses on energy yields, yield losses, performance metrics and performance loss rates (PLR, in %·y⁻¹), the latter calculated via Classical Series Decomposition and Year-on-Year methods. Pc-Si outperformed the others, with an average annual yield 2% higher than CIGS and 25–60% higher than a-Si and CdTe. Performance ratio (PR) values ranged from 0.88–0.85 for pc-Si and 0.87–0.82 for CIGS, while a-Si and CdTe showed lower PR (0.66–0.63 and 0.46–0.26, respectively). CdTe exhibited the highest degradation with PLR of −15.2 ± 4.45%·y⁻¹ (YoY), contrasting with pc-Si’s PLR −0.67 ± 0.89%·y⁻¹ (YoY), which aligns with warranty standards and global literature. Although based on a limited sample, the results offer valuable insights for PV deployment not only for Poland, but for cold-temperate climates, with relevance to Eastern Europe, Central Asia, and northern North America. The study highlights the importance of long-term, region-specific monitoring to guide technology selection and energy policy
Antimicrobial Properties of Analogs of Dimeric A-Type Proanthocyanidins in Food Matrices.
Full text linkPolyphenols with antimicrobial and antibiofilm properties are gaining popularity due to their natural origins and relatively safe nature, and they have met the interest of the food industry because of their possible applicability as food preservatives. We have investigated the effect of different analogs of dimeric A-type proanthocyanidins (PACs) on four food matrix models, including unprocessed meat, fish, vegetables and dairy products previously contaminated with susceptible food pathogens. The best effects were achieved when cherry tomato was used as the food matrix for all the target bacteria (Staphylococcus aureus CECT 828, Listeria innocua CECT 910 and Bacillus cereus UJA27q) and for both temperatures tested (6 and 25 °C). Moreover, several combinations of these analogs also showed synergistic effects, mainly on S. aureus CECT 828, which may allow these antimicrobials to be used at lower levels in food matrices, which would promote their sensory acceptability. However, further studies should be conducted next to understand the mechanisms of these synergistic activities between the phenolic compounds against foodborne pathogens, as well as to ensure the absence of toxic effects when used as food preservatives.This research was funded by the Andalusian Consejería de Economía y Conocimiento (FEDER program 2014–2020: grant number 1380669), Spain.

No full textReliability of Two Microhistological Analyses for Quantifying the Botanical Composition of Mediterranean Deer Diets
No full textMicrohistology analyses are well-supported techniques useful for studying herbivore diet composition, but they involve the correct identification and validated relative quantification of the plant species consumed, as well as the knowledge of possible biases inherent to methods. We analyzed two methods for quantifying the relative frequency of plant cuticles using an experimental procedure from laboratory-prepared samples. The factors affecting the precision of quantification were analyzed, the minimum sampling effort to detect all plants in the experimental mixture was estimated and the practical application on a complex real sample discussed, in order to describe a simple, standardized, and reliable procedure for studies of herbivore diet composition in Mediterranean ecosystems. Ten random mixtures were prepared with combinations of 40 known plant species, in different number and dry weight percentages. A total of 100 microscopic fields, distributed across 5 slides per sample, were analyzed using both quantification methods. Statistical analysis concluded that the two methods differed significantly. Higher precision was achieved with the method based on annotating the presence/absence of each species in each microscopic field, instead of the total number of times each plant was detected in each field. The important predictors of accuracy were the complexity of the sample and the proportion of plant material in the mixtures. The number of slides and microscopic fields did not significantly impact the quantification results, and no additional species were identified beyond 25 fields in the most complex samples. Due to its greater reliability, shorter analysis time, and reduced visual effort, the first method proved to be more efficient. This method is validated and useful in diet studies of overabundant populations of deer and extensive and transhumant livestock to evaluate the impacts of herbivores on ecosystems and generate sustainable management criteria in the use of pastures toward environmental and economic sustainability.Project P07-RNM-03087 (Junta de Andalucía, Spain), with the financial support of the Fondo Europeo de Desarrollo Regional (FEDER).

Redescubriendo la Historia de las Mujeres: espacios de resistencia económica, educativa y legal (ss. XVI-XXI)
Full text link-Catálogo de la exposición "Redescubriendo la Historia de las Mujeres: espacios de resistencia económica, educativa y legal (ss. XVI-XXI)", realizadas y organizadas bajo el marco del Proyecto Transversalizando la Historia: Formación, trabajo y derechos de las mujeres en la Edad Moderna y Contemporánea. Proyectos en materia de Igualdad de Género en la Universidad de Jaén, y en colaboración el Vicerrectorado de Igualdad, Diversidad y Responsabilidad Social y el Vicerrectorado de Cultura de la Universidad de Jaén.
-Comisariada y coordinada por Elizabeth García Gil.
-Lugar y periodo de exposición: Sala de Exposiciones Zabaleta. Edificio D1, Campus Las Lagunillas, Universidad de Jaén. Desde el 4 de septiembre hasta el 4 de noviembre de 2025.Aunque las mujeres representan el 50 % de la población mundial, su Historia aún está por escribir. Son muchos los tópicos que concitan al género femenino: que siempre dependían de un varón legalmente, que no trabajaban, que no ejercían puestos de responsabilidad… Por ello, se hace necesario realizar acciones que visibilicen su papel como agentes activas dentro de los entramados sociales, redescubriendo lo que historiográficamente se conoce como la Nueva Historia de las Mujeres.
La exposición explora su papel desde el siglo XVI hasta el XXI. A lo largo de 10 paneles se presentan cuáles han sido sus roles –activos y pasivos– dentro de las economías domésticas y laborales. Asimismo, se muestra cuál ha sido su capacidad jurídica a lo largo de la Historia. Los dos últimos paneles se han dedicado a las mujeres que rompieron el techo de cristal en las universidades andaluzas y que lograron llegar a la cima de la carrera científica: la cátedra universitaria. Se presentan sus logros más significativos y cómo la educación es el medio básico para alcanzar la independencia y el empoderamiento.
Esta acción de divulgación tiene como finalidad crear un conocimiento más inclusivo para la sociedad. No se trata de priorizar al género femenino, sino de sumar a los estudios ya existentes, que son mayoritariamente masculinos. De ahí la necesidad de introducirlas en entornos históricos pasados, identificándolas como agentes de cambios socioeconómicos. Una historia que aún está por escribir, descubrir y divulgar
