rotundata spreads when spores contaminate the body of nesting females, which in turn deposit the spores in the pollen they collect to feed their young (James, 2008). When adult bees emerge from managed nesting systems, they become contaminated with spores from the larvae that died in the ...
different flammability parameters, minimum ignition temperature (MIT) both in layer and in cloud, provides information regarding two different processes that might lead to fires and explosions: the ignition of dust dispersed in air as a dust/air mixture and the ignition of a dust layer deposit. ...
Sexual forms are produced in the autumn, they mate, and the females deposit eggs on the asparagus plant. Duration of a complete generation is about 15–19 days at 25°C. Egg. The eggs initially are green, but turn shiny black within 1–2 days. Females produce, on average, 10.5 ...
Most species deposit their eggs vertically in groups near their prey. On hatching, larvae remain clustered together on their eggshells for up to 1 day and often attack the un-hatched eggs. This sibling cannibalism is often beneficial for the one egg eaten (which may not have hatched), nearly...
Median Pb model ages are older for VHMS ore samples (Youanmi Terrane: 2993 Ma; EGST: 2714 Ma) than for the other process groups (Table 2). Komatiite-hosted Ni sulfide ores from the Youanmi Terrane have the youngest median Pb model ages (2265 Ma), while komatiite-hosted Ni sulfide ...
The deposit comprises a system of veins, in which the principal vein contains the biggst ore quantities, along with minor, but important, veins like Santa Rosa and Consuelo, which are subterranean and have sporadic outcrops (Nelson and Ganoza, 1999). The mine was mainly operated on a ...
Beavers fell trees, alter hydrologic regimes with their dams, and destroy existing vegetation in digging for mud to strengthen the dam. The flooding created by beaver ponds destroys flood-intolerant vegetation. Tides and storm surges deposit patches of debris that bury vegetation in coastal wetlands....
Collagen was chosen as a marker protein for ECM deposit for AOP 414, and the expression of collagen protein was determined after 24 h of BaP exposure at different concentrations. As shown in Fig. 4A, a pronounced increase of collagen secretion by HBE-1A1 cells was observed upon BaP ...
The predominant route of human exposure to PM is through the inhalation that enables them to enter and deposit in the airways and centriacinar regions of the lungs (Leikauf et al., 2020). Fine and ultrafine particulates can escape into the blood stream and affect the cardiovascular system. ...
