On a Common Mistake in the Description of the Photoelectric Effect
(AIP, 2019-11-01)
The photoelectric effect is one of the key experiments taught during first- or second-year university and high school modern physics courses. It is usually the first experiment to introduce light quantization and the concept ...
Systemic Tumors Can Cause Molecular Changes in the Hippocampus That May Have an Impact on Behavior after Chronic Social Stress
(MDPI, 2024-06-06)
Evidence indicates that chronic social stress plays a significant role in the development of
cancer and depression. Although their association is recognized, the precise physiological mechanism
remains unknown. In our ...

(UNED, 2020-12-16)
El reconocimiento de la tutela judicial efectiva que realiza el Derecho de la Unión Europea incide sobre la regulación nacional de la Administración de Justicia. No cabe duda de que la competencia para regular y actuar en ...
Dependence of Magnetic Properties of As-Prepared Nanocrystalline Ni2MnGa Glass-Coated Microwires on the Geometrical Aspect Ratio
(MDPI, 2024-06-06)
We have prepared NiMnGa glass-coated microwires with different geometrical aspect ratios, ρ = dmetal/Dtotal (dmetal—diameter of metallic nucleus, and Dtotal—total diameter). The structure and magnetic properties are ...
Hair cortisol determinants in 11-year-old children: Environmental, social and individual factors
(Elsevier, 2024-08)
Introduction
Children's exposure to chronic stress is associated with several health problems. Measuring hair cortisol concentration is particularly useful for studying chronic stress but much is unknown about hair ...
Non-destructive optical indices to estimate isoprenoids with nutritional value in packed rocket and spinach
(Elsevier, 2024-06)
The quantification of phytochemicals with nutritional benefits relies on accuracy yet time-consuming, expensive and destructive methodologies. In contrast, optical indices widely employed in disciplines such as ecology can ...
Ni supported on bioapatite for WGS: Improving catalyst stability and H2 selectivity by Pt-doping and thermochemical activation of the support
(Elsevier, 2024-05)
Catalytic properties of Ni and NiPt catalysts supported onto naturally derived hydroxyapatite (HAp) were investigated for the Water-Gas Shift (WGS) reaction in the 200–450 °C range. HAp was obtained by thermochemical ...
Genes involved in the adhesion and invasion of Arcobacter butzleri
(Elsevier, 2024-08)
Arcobacter butzleri is a foodborne pathogen that mainly causes enteritis in humans, but the number of cases of bacteraemia has increased in recent years. However, there is still limited knowledge on the pathogenic mechanisms ...
Parametric simulation tool for the enviro-economic evaluation of energy renovation strategies in residential buildings with life cycle thinking: PARARENOVATE-LCT
(Elsevier, 2024-06)
The EU regulations require long-term renovation strategies (LTRS) for the energy transition of the existing building stock, emphasising the importance of the whole-life carbon evaluation and the cost-effectiveness of the ...
