Investigation of the resin infusion process and mechanical performance of carbon fiber reinforced plastic composites from recycled carbon fiber (2023)

The disposal of Fiber Reinforced Composites (FRCs) waste is becoming a very critical aspect, from both a technical and an economic point of view, due to the continuous increase of the production of such a class of materials. Thus, the possibility to produce new composites by employing recycled materials is a crucial aspect both to guarantee the circularity of the manufacturing processes and the reduction of costs. In this work, the manufacturing process, together with the performance of a carbon

From “Green” to “Sustainable” Sample Preparation in Omics Studies in the Natural Product Field: Case Studies Dealing with Cannabis sativa L. (2023)

Plant metabolomics requires that as many metabolites as possible are extracted to obtain a reliable picture of the sample under study. Therefore, sample preparation plays a crucial role. In recent years, several efforts have been made to improve the environmental friendliness of sample preparation, including in the plant sector. However, the environmental friendliness of a method cannot be evaluated without also considering its productivity and, more importantly, its analytical performance to en

“Can I Dive with You?” Generally, No (2025)

Citizen science initiatives have demonstrated usefulness for public agencies responsible for the stewardship of commonly held resources. NOAA, NPS, USDA, USGS and others advertise multiple opportunities at Citizenscience.gov. Maritime archaeology has joined these citizen initiatives as acceptance of the field in academia and government has increased. NOAA’s Office of National Marine Sanctuaries supports several place-based efforts advancing heritage management and preservation across the sanctua

Maritime Archaeology of the Ancient Mediterranean (2019)

Maritime archaeology of the classical world explores the traders, travelers, pirates, fishermen, and warriors who sailed the ancient Mediterranean and its adjacent waters. Within the Greco-Roman Mediterranean, the sea and the distinctive opportunities it afforded for communication and interaction feature centrally to narratives of human development. Evidence for the socioeconomic world of seafaring comes not only from archaeological analysis of coastal and submerged sites, but also from literary

Spatial Evolution Mechanism of Vortex Structure in the Highly-loaded Helium Compressor Cascade (2023)

The highly-loaded design method of helium compressors can effectively solve the difficulty in compressing helium in High Temperature Gas-cooled Reactors (HTGR). But it also causes obviously different attack angle characteristics of blade surface loads in a highly-loaded helium compressor compared to air compressors. This difference inevitably affects separation characteristics and flow loss within the compressor. In the current study, the effects of highly-loaded design methods and changes in at

Artefacts from the Sea (2023)

Abstract Chapter 4 introduces the wrecked slave ships uncovered by maritime archaeologists. Few such vessels have been located, and fewer still have been explored in any detail; so all known examples, whatever their port of origin, are discussed in this analysis. Two ships stand out here: the British Henrietta Marie (lost in 1700) and the Danish Fredensborg (lost in 1768). They remain the only active transatlantic slavers to have been subject to both extensive excavation and detai

Citizen Science, Training, and Returns on Investment in Marine Archaeology (2025)

This chapter will focus on the participation of these "citizen volunteers" in archaeology, particularly maritime archaeology, the advantages and disadvantages of this participation, and the kinds of work in which volunteers may be most productively employed. It will draw on the more than 30 years of experience of the Maritime Archaeological & Historical Society (MAHS) in delivering high-caliber course content to avocational divers, its training programs and field schools, and the work of MAH

Exploring the Impact of a Sleep App on Sleep Quality in a General Population Sample: Pilot Randomized Controlled Trial (Preprint) (2022)

BACKGROUND A third of adults in Western countries have impaired sleep quality. A possible solution involves distributing sleep aids through smartphone apps, but most empirical studies are limited to small pilot trials in distinct populations (eg, soldiers) or individuals with clinical sleep disorders; therefore, general population data are required. Furthermore, recent research shows that sleep app users desire a personalized approach, offering an ind

Effectiveness of Magnesium Supplementation on Sleep Quality and Mood for Adults with Poor Sleep Quality: A Randomized Double-Blind Placebo-Controlled Crossover Pilot Trial (2024)

Objectives: Conduct a randomized double-blind placebo-controlled crossover pilot trial on adults with nonclinical insomnia symptoms to examine the effectiveness of magnesium supplementation on sleep quality and mood. Methods: Participants (N = 31 adults, M age = 46.01) were randomized to either the Magnesium Condition (1 g/d of Upgraded MagnesiumTM) or Placebo Condition for 2 weeks. Following a two-week washout, participants engaged in the alternative condition. Standardized self-reports (i.e.,

Effectiveness of Magnesium Supplementation on Sleep Quality and Related Health Outcomes for Adults with Poor Sleep Quality: A Randomized Double-Blind Placebo-Controlled Crossover Trial (2024)

Abstract Objectives: Conduct a randomized double-blind placebo-controlled crossover trial on adults with nonclinical insomnia symptoms to examine the effectiveness of magnesium supplementation on sleep quality and mood. Methods: Participants (N = 31 adults, M age = 45.49) were randomized to either the Magnesium (1 g/d) or Placebo Condition for 2 weeks. Following a two-week washout, participants engaged in the alternative condition. Standardized self-reports (i.e., Insomnia Severity Index
