Silene taxonomy, traditionally based on morphological characteristics, is now driven by DNA sequence analysis. While the usefulness of both and molecular methods remains undisputed, there an interest in identification characteristics useful taxonomy. A quantitative analysis seeds belonging to species presented here seed image samples for 95 populations 52 (49 3 related species). According silho...

The main energy source powering the brain is glucose. Strong energy needs of our nervous system are fulfilled by conveying this essential metabolite through blood via an extensive vascular network. Glucose then reaches brain tissues by cell uptake, diffusion and metabolization, processes primarily undertaken by astrocytes. Deprivation of glucose can however occur in various circumstances. In pa...

The TM series of preneoplastic mammary outgrowth lines was derived from the transplantation of the FSK mammary cell lines into the cleared mammary fat pads of syngeneic female BALB/c mice. The tumor-producing capabilities of the 6 TM outgrowth lines varied from high (TM2, -4, -6) to low (TM9, -10) to nil (TM3). Outgrowth lines 2, 4, and 6 each segregated into sublines of high and low tumor pote...

The possibility of using cellulose from the cell walls of kenaf, an annual herbaceous crop, for the production of bicomposites was investigated in this study. The composites were prepared using LDPE, as a matrix, the extracted cellulose, as filler and PEG as a plasticizer. The characterization of biocomposites was then performed with optimized thermo-mechanical properties and propensity to envi...

Toward adaptive underwater locomotion, this paper presents the experimental results of a fish-like swimming robot that we have newly developed. By using motor control with only one degree of freedom, this robot exhibits surprisingly rich behavioral diversity in three dimensional underwater environment. This paper focuses on some of the behavior variations this robot exhibits, i.e. forward, turn...
