Leaf senescence is a natural age-dependent process that is induced prematurely by various environmental stresses. Typical alterations during leaf senescence include breakdown of chlorophyll, a shift to catabolism of energy reserves, and induction of senescence-associated genes, all of which can occur during submergence, drought, and constant darkness. Here, we evaluated the influence of the sub...

Three systems for "unscrambling" helium speech produced at simulated depths of 800 and 1000 feet were evaluated. Recordings of the Modified Rhyme test read by an experienced male diver in a pressurized helium atmosphere were processed through three commerical frequency-shifting devices. The intelligibility of words passed through these systems was compared to scores obtained when the same heliu...

Saline water intrusion into freshwater aquifers is a major geohydraulic problem relevant to coastal environment. Apart from contaminating the fresh groundwater resources, saltwater alters geotechnical properties of aquifer materials, affecting resource planning and management. The present study focuses on an in-depth laboratory investigation influence submergence sand. fine sand sample was subm...

This paper develops a new class of functional depths. A generic member this is coined $J$th order $k$th moment integrated depth. It based on the distribution cross-sectional halfspace depth function in marginal evaluations (in time) random process. Asymptotic properties proposed depths are provided: we show that they uniformly consistent and satisfy an inequality related to law iterated logarit...
