We used speckle visibility spectroscopy to measure the time-resolved dynamcis of avalanching down the inclined surface of a granular material in a half-full rotating drum operating in the slumping regime. The distribution of the avalanche period, t(d), rest time between them, t(r), and peak particle velocity fluctuation, δv(p)(2), are all normally distributed. While the distributions of the two...

While Prior Subspace Analysis (PSA) has proved an effective tool for transcribing mixtures of snare, kick drum and hi-hat both in the “drums-only” case and in the presence of pitched instruments attempts to extend it to deal with increased numbers of drum types have met with mixed results. To overcome this an automatic modeling and grouping procedure has been developed which groups drum events ...

OBJECTIVE To identify the allergen(s) responsible for mid April-mid May nasobronchial allergy seen in North India. DESIGN Case control study. SETTING Children living in and around Chandigarh (urban, rural). SUBJECTS 39 children suffering from wheat harvest period (mid April-mid May) respiratory allergy along with randomly selected controls. METHODS Aerobiological surveys were done from ...

For the early Iron Age Elymian town on Monte Polizzo, inland western Sicily, hulled barley was the dominant cereal, followed by emmer and free-threshing wheat. The dominant legume was Vicia faba. In the contemporary Greek harbour town of Selinunte on the southern coast of western Sicily, free-threshing wheat was dominant, while hulled barley and the legume V. ervilia were subdominant. For Selin...

We examined the patterns of habitat-specific mortality for newly settled red drum (Sciaenops ocellatus) using an experimental mesocosm approach. Experiments were designed to analyze prey vulnerability and fish rearing-type (wild-caught or hatchery-reared) in estuarine habitats of varying structural complexity including marsh (Spartina alterniflora Loisel), oyster reef (Crassostrea virginica Gme...

A soft-sphere discrete particle model was used to simulate mixing behavior of solid substrate particles in a slow rotating drum for solid-state fermentation. In this approach, forces acting on and subsequent motion of individual particles can be predicted. The (2D) simulations are qualitatively and quantitatively validated by mixing experiments using video and image analysis techniques. It was ...
