Rhizophora mangle L., one of the most common mangrove species, has an aerial structure system that gives it stability in permanently swampy soils. In fact, these structures, known as "aerial roots" or "stilt roots", have proven to be peculiar branches with positive geotropism, which form a large number of roots when in contact with swampy soils. These organs have a sympodial branching system, w...

Background:Melanogenesis begins with the oxidation of L-tyrosine to L-Dopa by tyrosinase. Inhibition of tyrosinase could be effective in treatment of complications such as skin lesions, eczema and melasma. Inhibition of tyrosinase could be effective in treatment of those complications. The aim of this study was to determine inhibitory activity on tyrosinase and antioxidant activity of Ast...

The regulation of floral organ number is closely associated with floral meristem size. Mutations in the gene FLORAL ORGAN NUMBER1 (FON1) cause enlargement of the floral meristem in Oryza sativa (rice), resulting in an increase in the number of all floral organs. Ectopic floral organs develop in the whorl of each organ and/or in the additional whorls that form. Inner floral organs are more sever...

A willing seller and buyer voluntarily agree upon the price for exchange of X dollars one Y widget. The trade satisfies some their human wants. Both parties are better off having made profitable or they would not have transacted. Once widget becomes a life-saving organ, like kidney, all bets according to present prohibition on trades between two seeking themselves through an exchange. We conten...

Lycium depressum L. is the only native tree-like life-form species inhabited in saline and alkaline regions of Turkmen Sahra located at Golestan province in Northern Iran. During past years, efforts have been made to increase vegetation cover of the area by cultivation of L. depressum L. to reduce water and wind erosions and dust storm challenges; however, the cultivation of t...

The genetic analysis of development has revealed the importance of small sets of interacting genes in most morphogenetic processes. The results of gene interactions have so far been examined intuitively. This approach is largely sufficient when one deals with simple interactions, a feedback circuit for example. As more components become involved, however, it is difficult to make sure that the i...

-We evaluated aerial photography (full coverage, using fixed-wing aircraft) and aerial video (transects, using helicopter) surveys to estimate the population of Laughing Gull (Larus ahicilla) nests in Jamaica Bay, NewYork, during June 1992-1995. We counted 4,920 nests in the colony using aerial photography and estimated 5,367 nests using aerial video in 1992. In 1993-1995, we respectively count...

Because of the mechanical situation, aerial carrier condition, environment condition and usage maintenance of the aerial camera, faults always occur. So it is necessary to check and maintain the aerial camera on the ground, and the interior structure of the aerial camera is very complex, and the aerial camera is composed by many circuit boards, and the checking must be performed from the whole ...
