Molecular caving
How is the ring assembled? A set of conserved contractile ring proteins have been identified and characterized using genetic, biochemical and proteomic approaches in model organisms ranging from yeasts, plants, worms, and flies to sea urchin eggs and mammalian cells. These proteins, many of which organize actin in some manner Actin filaments in the ring may be derived both from pre-formed filam...
متن کاملEnergy expenditure in caving
The aim of this study was to determine the energy expenditure of a group of cavers of both genders and different ages and experience during a 10 hour subterranean exploration, using portable metabolimeters. The impact of caving activity on body composition and hydration were also assessed through bioelectrical impedance, and nutritional habits of cavers surveyed. During cave activity, measured ...
متن کاملCharacteristics of Strata Behavior during Thick Seam Mining by Fully-Mechanized Top Coal Caving in a Loess-Covered Gullied Region
This study systematically investigates the overburden movement and strata behavior at a fully-mechanized top coal caving (FMTCC) face in a thick coal seam in a loess-covered gullied region by field measurement and theoretical analysis. A comparative analysis was performed to examine how the attitude of surface gullies and the structure of overburden affect face support resistance. The character...
متن کاملAnalysis of Overlying Strata Movement and Behaviors in Caving and Solid Backfilling Mixed Coal Mining
Based on techniques of close upper protective coal-rock layer mining, relieved gas extraction, and underground gangue washing-discharging-backfilling, this paper initiates the concept of mixed fully-mechanized coal mining, which combines a solid backfilling method and a caving method (hereinafter referred to as “backfill and caving mixed mining”). After the principle and key techniques are intr...
متن کاملCaving for “Pink Puffers” and “Blue Bloaters”
The terms “Pink Puffers” and “Blue Bloaters” have been around for many years. They are used in a colloquial sense by speleologists to describe how cavers react to an elevated concentration of carbon dioxide (CO2) and reduced oxygen (O2) in a cave’s “foul air” atmosphere. Foul air is only found in a small number of Australian caves and is defined as having a noticeable abnormal physiological eff...
