Summary: Roughness, pigment impurities, and neoformed minerals are important factors affecting the reflectance of painted surfaces. Other factors such as the total thickness of the paint layer and the amount of binder should also be considered. The distribution of pigments and binder in the paint system, as well as their interaction, are key to understanding reflectance values.

Summary: This study explored the impact of pesticide exposure on the gut microbiome and the role of probiotics in mitigating its effects. The research found that frequent exposure to pesticides did not alter the composition of the intestinal microbiota but increased the abundance of Lipopolysaccharide, potentially leading to chronic inflammation. Supplementation with the probiotic P9 helped maintain gut microbiome homeostasis and reduce the abundance of pathogens. Additionally, P9 intake significantly increased the concentrations of uridine and 5-oxoproline, while also alleviating immune factor disorder and promoting pesticide residue excretion.

Summary: Aromatics in petroleum mixtures are important in various aspects including exploration, refining, and environmental emissions. This study presents a simple and fast method called aromatic-selective size exclusion chromatography (ASSEC) for quantifying aromatics in petroleum samples. ASSEC can provide a comprehensive analysis of aromatics content across the whole boiling range of petroleum samples and can be used for industrial applications such as optimizing conversions of petroleum to petrochemicals. Further optimization can reduce differences between ASSEC and other analytical techniques for determining aromatic content.

Summary: This study presents a mid-infrared spectroscopy-based method for predicting concentrations of individual fatty acids and relevant sum parameters in human milk. The method showed good results in external validation and can accurately predict important fatty acid sum parameters and individual fatty acids. The study also investigated the effect of different clinical parameters on the fatty acid profile in human milk and found changes in certain sum parameters over the course of lactation. Additionally, the method was found to have clear advantages in terms of environmental friendliness compared to traditional gas chromatography-mass spectrometry methods. Overall, this method represents a high-throughput, green alternative to established techniques.

Summary: A versatile method is developed to enhance the protective efficacy of silane-based materials against rainwater and organic pollutants by tuning their wetting properties. This is achieved through blending a commercially available silane product with a fluoropolymer and silica nanoparticles to modify the surface morphologies of the coatings. The synergistic effect of surface structure and chemistry leads to the production of superamphiphobic coatings.

Summary: The study aimed to characterize the limestone used in the ancient city of Pella in Macedonia, Greece, revealing variability in stone nature and deterioration within monuments due to factors like water absorption and biological colonization. Through microanalysis and testing, the mineralogical, chemical, mechanical, and thermal properties of the stones were fully characterized. Results showed the dominance of calcite as the main mineral phase, with traces of quartz and clay minerals detected. Thermographical measurements indicated limited decay due to ambient temperature variation, while high porosity and low compressive strength suggest vulnerability of the stone and necessity for conservation measures.

Summary: Chemical treatment of skeletal remains can reduce overall DNA quality and quantity but has no significant impact on stable isotope ratio analysis. Examination of treated and untreated human remains through histological and stable isotope analysis reveals that treated remains exhibit better preservation compared to untreated remains. Stable isotope ratio analysis is viable for both treated and untreated remains, regardless of their origin.

Summary: This paper presents the outcomes of a microcontextual geoarchaeological study conducted on earthen dwellings from the Early Iron Age village of Cerro de San Vicente. The study employed soil micromorphology, lipid biomarker analysis, XRD, and XRF analyses to investigate various aspects of the dwellings, including construction materials, site formation processes, and daily life practices. The results have shed light on the construction layers, floor use, maintenance, repaving, periods of abandonment and decay, and the presence of lipid biomarkers associated with dwelling functionality. The study significantly contributes to our understanding of ancient construction practices and the utilization of domestic spaces during the Early Iron Age.
