tomato is one of the sensitive fruits to mechanical impacts and physical tensions. the mostmechanical damages arise from handling which results in reducing tomato quality. in this study,impact energy effect has been studied in 3 different levels 0, 0.14 and 0.25 j by a pendulum impactapparatus, on changes of physicochemical properties of tomato, hybrid variety shiva f1, includingripening factor...

[1] Although shelf seas account for only 7% of the oceanic surface area, recent observations demonstrate that they host significant ocean-atmosphere CO2 fluxes. A mechanism implicated in driving a significant CO2 sink in the temperate shelf seas is the Continental Shelf Pump. Here we present an analysis of the impact of sea-level rise, and the consequent flooding of continental shelves, on the ...

Potential energy released from the capsize of ice-shelf fragments (icebergs) is the immediate driver of the brief explosive phase of ice-shelf disintegration along the Antarctic Peninsula (e.g. the Larsen A, Larsen B and Wilkins ice shelves). The majority of this energy powers the rapidly expanding plume of ice-shelf fragments that expands outward into the open ocean; a smaller fraction of this...

The shelf-life of a drug product is the time that the average drug characteristic (e.g., potency) remains within an approved specification after manufacture. The United States Food and Drug Administration (FDA) requires indication for every drug product of a shelf-life on the immediate container label. Since the true shelf-life of a drug product is typically unknown, it has to be estimated base...

Fetuses were obtained from CD-1 mice at a time estimated to be 12 h prior to vivo secondary palate closure. One of the palatal shelves of each partially dissected fetal head was lesioned in one of five ways, the other left intact to serve as control. Single transverse cuts extending the width of the shelf were made at one of three positions along the longitudinal axis of the shelf: one-third, o...

A jet flowing in the Kelvin wave propagation direction along the seaward side of a continental slope is found to decrease in strength as it leaks mass onto the continental shelf. As a result, a shelf break jet flowing in the opposite direction is induced on the shelf. The combination of these two flows creates a decaying, high-pressure tongue centered about the shelf break. An idealized, reduce...

Melt water from the floating ice shelves at the margins of the southeastern Weddell Sea makes a significant contribution to the fresh water budget of the region. In February 2005 a multi-institution team conducted an oceanographic campaign at Fimbul Ice Shelf on the Greenwich Meridian as part of the Autosub Under Ice programme. This included a mission of the autonomous submarine Autosub 25 km i...

On the continental shelf near Cape Hatteras, cool fresh Mid-Atlantic Bight and warm salty South Atlantic Bight shelf waters converge alongshelf 90% of the time, causing strong alongshelf gradients in temperature, salinity, and density known as the ‘Hatteras Front’. Mechanisms of shoreward transport in this region have long been a topic of interest, since many commercially important species spaw...

Cellular and subcellular events during reorientation of the palatal shelf in hamster fetuses are described. An alteration in the morphology of the epithelial and the mesenchymal cells is observed during shelf realignment from a vertical to a horizontal plane. The mesenchymal cells elongate and subsequently appear to protrude in the medially bulging palatal shelf. Microtubules, microfilaments an...
