Study of Water Safety Plan
The use of Microfiltered Water Dispensers (MWDs) is increasing in offices, companies, or commercial facilities, as a response to plastic pollution. Despite their widespread use, poor data are available about the water quality and pathogens developed. Starting from a high contamination found in MWDs, a Water Safety Plan (WSP) was implemented on 57 MWDs to improve the water quality. To assess the effectiveness of WSP during the period 2017–2021, the environmental monitoring of heterotrophic plate counts (HPCs) at 36 °C and 22 °C, Enterococcus spp., Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and Clostridium perfringens, as prescribed by Italian regulation for drinking water, was conducted.

Studies on Traditional Ecological Knowledge
Traditional ecological knowledge (TEK) dominated by traditional populations, especially fishermen and women, has been the object of scientific research from different perspectives, disseminating information on fauna and flora in different environments. Such interest refers to the importance that the set of information that these populations have on the dynamics of the local environment and the relationship with the environment in which they live. Generally, the transmission of this knowledge happens from generation to generation; however, it is still little valued by studies related to natural sciences. The study of this type of traditional ecological knowledge can support scientific studies and, therefore, help to fill the gaps in the understanding between the relationship between human activities and different ecosystems.

Struthiosaurinae
Struthiosaurinae is a subfamily of ankylosaurian dinosaurs from the Cretaceous of Europe. It is defined as "the most inclusive clade containing Europelta but not the North American Cedarpelta, Peloroplites, Sauropelta or Edmontonia" while being reinstated for a newly recognized clade of basal nodosaurids. Struthiosaurinae appeared at about exactly the same time as the North American subfamily Nodosaurinae. Struthiosaurines range all across the Cretaceous, the oldest genus being Europelta at an age of 112 Ma and the youngest being Struthiosaurus at about 85–66 Ma. It was originally mentioned by Franz Nopcsa in 1923 as a subfamily of Acanthopholidae, along with the previously defined Acanthopholinae. The family has gone through many taxonomic revisions since it was defined by Nopcsa in 1902. It is now recognized as a junior synonym of the family Nodosauridae. The subfamily now includes the genera Anoplosaurus, Europelta, Hungarosaurus, and Struthiosaurus, designated as the type genus. Because of the instability of Acanthopholis, the generic namesake of Acanthopholinae, and its current identification as a nomen dubium, Struthiosaurinae, the next named group, was decidedly used over the older one. A review of ankylosaur osteoderms was published in 2000, and reviewed the armour of Struthiosaurinae. The group was represented by the single genus Struthiosaurus, known from head, cervical, dorsal, sacral, and caudal scutes. Only a few head osteoderms were identified, so it is unknown how much of the skull was armoured. Many cervical and dorsal scutes have been preserved alongside species of Struthiosaurus. They include cervical bands, which are groups of osteoderms fused together and attached to the vertebrae, and large spines found on the shoulders of nodosaurids like Sauropelta and Edmontonia, although it is not known if the spines were fused like the later of separate like the former. It is quite possible that small ovoid scutes found on Struthiosaurus could have formed a pelvic shield like polacanthids. The caudal scutes of struthiosaurines are small and rough. Even though osteoderms are well-known, it is not certain where they were positioned on the body.

Structure-Borne Noise in Offshore Piling
The growing demand for renewable energy supply stimulates a drastic increase in the deployment rate of offshore wind energy. Offshore wind power generators are usually supported by large foundation piles that are driven into the seabed with hydraulic impact hammers or vibratory devices. The pile installation process, which is key to the construction of every new wind farm, is hindered by a serious by-product: the underwater noise pollution.

Structure of the Earth
The internal structure of the Earth is layered in spherical shells: an outer silicate solid crust, a highly viscous asthenosphere and mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core. Scientific understanding of the internal structure of the Earth is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanoes or volcanic activity, analysis of the seismic waves that pass through the Earth, measurements of the gravitational and magnetic fields of the Earth, and experiments with crystalline solids at pressures and temperatures characteristic of the Earth's deep interior.

Strengthening Collaborative Food Waste Prevention in Peru
Inefficient management and handling of organic waste generated by the food service sector is a big global challenge. In addition to the negative environmental impacts of food waste, the effect of the amount of food that is wasted when it is not handled properly is even more alarming.

Streamflow Duration
Streamflow Duration: The length of time a stream has surface flow or conversely, has no surface flow. It is one of several dimensions that characterize flow regimes of streams[1]. Streamflow duration is used to differentiate reaches into discrete classes (e.g., perennial, intermittent, and ephemeral) for water resource management.

Stream Ecological Integrity
Streams and rivers provide important services to humans, and therefore, their ecological integrity should be a societal goal. Although ecological integrity encompasses structural and functional integrity, stream bioassessment rarely considers ecosystem functioning. Organic matter decomposition and ecosystem metabolism are prime candidate indicators of stream functional integrity.

Strategies of Selenium Biofortification
Selenium (Se) is an essential trace element for humans and animals. Biofortification is a quick, efficient, and sustainable way to lower micronutrient deficiencies. The strategies of biofortification are the approaches employed to achieve biofortification. Plants and animal produce are classified as biofortified when there is an increase in the Se content in the edible portions of plants and food animals.

Strasburg, Virginia
Strasburg /ˈstrɑːzbɜːrɡ/ is a town in Shenandoah County, Virginia, United States , which was founded in 1761 by Peter Stover. It is the largest town by population in the county and is known for its grassroots art culture, pottery, antiques, and American Civil War history. Strasburg has blended the nostalgia of the past with the inspiration of the future. The population was 6,398 at the 2010 census.
