Mouse livers were perfused in situ through the portal vein with the disaccharides sucrose, lactose, maltose, and cellobiose in hypertonic concentrations (0.5 M). This treatment resulted in plasmolysis of the hepatocytes and splitting of the gap junctions and zonulae occludentes. The junctions split symmetrically, leaving a half-junction on each of the two separated cells. The process of junctio...

M-tree is a dynamic access method suitable to index generic “metric spaces”, where the function used to compute the distance between any two objects satisfies the positivity, symmetry, and triangle inequality postulates. The M-tree design fulfills typical requirements of multimedia applications, where objects are indexed using complex features, and similarity queries can require application of ...

The relationship between the induction of DNA damage as reflected by sister chromatid exchange (SCE) formation and morphological transformation in exponentially growing Syrian hamster embryo cells was determined quantitatively after split doses of chemical or physical carcinogens. With split doses of carcinogen separated by 2 to 24 hr, only N-acetoxy-2-fluorenyl-acetamide (0.50 microgram/ml) en...

to evaluate the effects of biological phosphorous, chemical fertilizers and limited irrigation regime on quantitative and qualitative characteristics of two different grain sorghum cultivars (kimiya and speedeh), this experiment was conducted in research farm of college of agriculture, university of tehran during 2009 growing season. the experimental treatments were arranged as split split plot...

It is shown that Witten's star product in string field theory, defined as the overlap of half strings, is equivalent to the Moyal star product involving the relativistic phase space of even string modes. The string field ψ A (x µ [σ]) can be rewritten as a phase space field of the even modes A (x µ 2n , x 0 , p µ 2n) , where x µ 2n are the positions of the even string modes, and p µ 2n are rela...

An efficient numerical algorithm is presented for massively parallel simulations of dispersion-managed wavelength-division-multiplexed optical fiber systems. The algorithm is based on a weak nonlinearity approximation and independent parallel calculations of fast Fourier transforms on multiple central processor units (CPUs). The algorithm allows one to implement numerical simulations M/2 times ...

Taro [Colocasia esculenta (L.) Schott] is a member of the Araceace family that is a staple food for many people in developing countries in Africa, Asia and the Pacific Islands. It is widely grown in Uganda but the extent of its production and consumption is not known, partly because it has been ignored as legitimate crop for research and development (R&D), and it is managed outside the conventi...

OBJECTIVES Bowel cleansing is necessary before colonoscopy, but is a burden to patients because of the long cleansing time and large dose volume. A low-volume (2 L) hypertonic polyethylene glycol-ascorbic acid solution (PEG-Asc) has been introduced, but its possible dehydration effects have not been quantitatively studied. We compared the efficacy and safety including the dehydration risk betwe...
