In September 1969, the Florida barge spilled 700,000 L of No. 2 fuel oil into the salt marsh sediments of Wild Harbor, MA. Today a substantial amount, approximately 100 kg, of moderately degraded petroleum remains within the sediment and along eroding creek banks. The ribbed mussels, Geukensia demissa, which inhabit the salt marsh creek bank, are exposed to the spilled oil. Examination of short...

Objective We present an approach for detecting mitochondria in electron microscopy images of brain tissue and demonstrate it on the rat neuropil. This would enable the study of statistics of mitochondria and their location relative to other structures such as cell boundaries, vesicles and synapses. Neural tissue from the Lateral part of the rat's brain was cut into 50nm slices and photographed ...

introduction: we have recently reported the presence of two potassium currents with 598 and 368 ps conductance in the rough endoplasmic reticulum (rer) membrane. the 598 ps channel was voltage dependent and atp sensitive. however, the 368 ps channel was rarely observed and its identity remained obscure. since cationic channels in intracellular organelles such as mitochondria and rer play import...

Reinforced concrete-framed buildings are commonly preferred to other types of in Turkey. In these buildings, a two-way slab with beams, flat, waffle, and ribbed widely used. building design, determining the best type that will perform well under gravity lateral loads, least cost, is required. However, proper selection has generally been overlooked by designers due emphasis on structural members...

Abstract The main indicator of the quality cotton harvesting machine is completeness collecting grown crop into bin, which usually 3-4% lower than spindles. This because remover vertical-spindle machines does not fully remove bobbins from Part wound on spindle carried away working zone without being removed. phenomenon called “cotton carry-over”. According to previous authors, “Carry-over” reac...

To explore the nonlinear bond behaviour between ribbed bar and concrete, combined with characteristics of concrete meso-structure surface considering frictional resistance mechanical interlocking rebar a meso-scale model is established. Based on good agreement simulation results experimental results, failure mechanism discussed, distribution stress steel are analysed. Furthermore, based meso nu...
