A major goal of the ONR Mine Burial Prediction (MBP) Program is to provide the operational Navy simple models for predicting subsequent mine burial by scour which work with a known and useful degree of accuracy in regions of strategic interest, defined initially as sandy inner shelves dominated by waves. In order to be useful under real world conditions, such models must be reasonably accurate ...

The paper presents results of 21 deployments of an instrumented, mine-like cylinder over soft cohesive sediment seafloor at two sites. The focus of this work is the sediment penetration phase. The paper gives a statistical description of the sediment penetration dynamics and compares the observed behavior with predictions from an impact burial software package. It is shown that, due to simplifi...

The aim of this paper is to give a bioarchaeological overview of the graves with multiple simultaneous burials in the South-East Estonian Siksälä cemetery (12th– 15th cc). Six inhumation graves with a total of 16 individuals were analysed. The studied multiple burials represent various age and gender combinations. Any relations between skeletal pathologies and grave goods could not be observed....

The efficiency of gas transport to the free and upper troposphere in convective clouds is investigated in an axisymmetric dynamic cloud model with detailed microphysics. In particular, we examine the sensitivity of gas transport to the treatment of gas uptake by different ice hydrometeors. Two parameters are used to describe this uptake. The 5 gas retention coefficient defines the fraction of d...

This study, conducted at the University of Tennessee's Anthropological Research Facility (ARF), lists and ranks the primary chemical constituents which define the odor of decomposition of human remains as detected at the soil surface of shallow burial sites. Triple sorbent traps were used to collect air samples in the field and revealed eight major classes of chemicals which now contain 478 spe...

1 Atract-Falling of mine through air, water, and sediment is investigated experimentally and theoretically. Two experiments were conducted to drop cylindrical mine with the density ratio around 1.8 into shallow water (around 13 m deep) in the Monterey Bay (Exp-1) and into the Naval Postgraduate School’s swimming pool (Exp-2). During the experiments, we carefully observe mine track and burial de...

AIM Asphyxia is the primary cause of death among avalanche victims. Avalanche airbags can lower mortality by directly reducing grade of burial, the single most important factor for survival. This study aims to provide an updated perspective on the effectiveness of this safety device. METHODS A retrospective analysis of avalanche accidents involving at least one airbag user between 1994 and 20...

To mitigate global climate change, a portfolio of strategies will be needed to keep the atmospheric CO2 concentration below a dangerous level. Here a carbon sequestration strategy is proposed in which certain dead or live trees are harvested via collection or selective cutting, then buried in trenches or stowed away in above-ground shelters. The largely anaerobic condition under a sufficiently ...
