Penetration of Stomata by Liquids

Spontaneous Penetration of Liquids into Capillaries and Porous Membranes Revisited.

A critical review of the problem of spontaneous penetration of a wetting liquid into pore channels shows that no theory exists to quantitatively predict the initial stage of imbibition. Since C. H. Bosanquet (1923, Phil. Mag. 45, 525), the theory operates with an universal velocity U(Bosanquet)=(2gammacosstraight thetarhor(1/2), with gamma being the surface tension, straight theta the contact a...

Internalization of Salmonella enterica in leaves is induced by light and involves chemotaxis and penetration through open stomata.

Outbreaks of salmonellosis related to consumption of fresh produce have raised interest in Salmonella-plant interactions leading to plant colonization. Incubation of gfp-tagged Salmonella enterica with iceberg lettuce leaves in the light resulted in aggregation of bacteria near open stomata and invasion into the inner leaf tissue. In contrast, incubation in the dark resulted in a scattered atta...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
