The Delft Sand, Clay & Rock Cutting Model
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, atmospheric rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the blade, are discussed. For each case considered, the equations/model for the cutting forces, power and specific energy are given. The models are verified with laboratory research, mainly at the Delft University of Technology, but also with data from literature.

Rating
0.0 stars

In this enlightening lecture, Dr. Ayana Omilade Flewellen, a distinguished professor at Stanford University, explores the intersections of black feminism, archaeology, and storytelling. She advocates for the centrality of black women's experiences in historical narratives and discusses the multifaceted role of archaeology in public history and cultural preservation. The talk features her work with the Society of Black Archaeologists and Diving With a Purpose, emphasizing the need for diversity in the field and the significance of underwater archaeology in heritage conservation. Dr. Flewellen also presents the Estate Little Princess project in St. Croix, a groundbreaking initiative combining terrestrial and underwater archaeology to uncover and preserve Afro-Crucian history. The lecture is a compelling call to recognize and engage with the rich, often untold, histories that shape our world, making it a valuable resource for students, educators, and anyone interested in the dynamic fields of archaeology and cultural heritage.

Dredging Engineering: Special Topics
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

In dredging, production estimating is carried out mainly with analytical physical models of the different dredging processes.
Slurry transport of settling slurries and cutting processes in sand, clay and rock are already covered in two other books by the author.
Other processes like hopper sedimentation and erosion, water jet fluidization, cutter head spillage, pump/pipeline dynamics and clamshell dredging are covered in this Special Topics Edition.
New topics may be added in the near future.

A Historical Ecology of Slavery in the Danish West Indies
Unrestricted Use
Public Domain
Rating
0.0 stars

A Historical Ecology of Slavery in the Danish WThis lecture by Justin Dunnavant at UC Santa Cruz focuses on the intersection of historical ecology and slavery in the Danish West Indies. He delves into various aspects, including the impact of the slave trade globally, archaeological methods for studying slave shipwrecks, and the ongoing relevance of archaeology in contemporary communities.

The key takeaway from this lecture is a deeper understanding of how the slave trade influenced global ecosystems and societies, particularly through the lens of historical ecology. Dunnavant emphasizes the critical role of archaeology in uncovering the material histories of enslaved peoples and how these insights can guide contemporary cultural and environmental preservation.

Pre-Watch Preparation
Contextual Background: Provide students with a background on the Danish West Indies, the transatlantic slave trade, and basic principles of archaeology and ecology. This could be in the form of a short reading assignment or a classroom lecture.
Key Vocabulary: Introduce key terms and concepts that will appear in the video, such as "historical ecology," "maritime archaeology," and "sustainable archaeology," to ensure students are not bogged down by unfamiliar terminology.

Justin Dunnavant begins the lecture by outlining his research focus on the historical ecology of slavery in the Danish West Indies, emphasizing the integration of archaeological methods with ecological awareness.

He introduces the significance of the transatlantic slave trade in shaping the economic and cultural landscapes of the Virgin Islands, with particular attention to the archaeological evidence from shipwrecks.

Dunnavant discusses his work at the Estate Little Princess, a former Danish plantation on St. Croix, describing the artifacts found and their cultural implications.

The lecture highlights the environmental impacts of slavery, such as deforestation and landscape modification, which were integral to the plantation economy.

The role of community involvement in archaeological practice is underscored, promoting an inclusive approach to studying and preserving history.

Dunnavant presents a case for sustainable archaeology that respects both cultural heritage and the natural environment, aiming to mitigate the impacts of archaeological activities.

The talk concludes with a discussion on the importance of continued research and education to further explore the complex legacies of slavery in the Caribbean.
