Light sensing by photoreceptors controls phototropism, chloroplast movement, stomatal opening, and leaf expansion in plants. Understanding the molecular mechanism by which these processes are regulated requires a quantitative description of photoreceptor dynamics. We focus on a light-driven signal transduction mechanism in the LOV2 domain (LOV, light, oxygen, voltage) of the blue light photorec...

A simple and sensitive solid phase spectrophotometric method for the determination of cobalt is proposed based on the reaction between cobalt and xylenol orange (XO). The reaction product is fixed on the anionic exchanger resin sephadex QAE A-25 at pH= 5. The optical absorbance of the anionic gel like resin, packed in a 1.00 mm cell is directly measured at 588.0 nm. The linear range of calibrat...

Microcosms, each consisting of 2L natural surface seawater maintained in 2.3-L glass bottles, were immersed at a depth of 6m. The renewal of 10% of microcosm volumes was carried out every other day. Phytoplankton-containing seawater was used for renewal (previously filtered through 25-, 50- or 200-μm cut-off). Phytoplankton community pigment analysis (by HPLC) and flow cytometry analysis were p...

Section 404(c) regulation sets forth the conditions that plan fiduciaries must meet to be relieved of liability for the consequences of employees' control over their accounts. After reviewing applicable laws and regulations, the author concludes that employers desiring to provide employees with education and/or advice services through a third party should be able to do so while still obtaining ...

We make hundreds of decisions every day, many of them extremely quickly and without much explicit deliberation. This motivates two important open questions: What is the minimum time required to make choices with above chance accuracy? What is the impact of additional decision-making time on choice accuracy? We investigated these questions in four experiments in which subjects made binary food c...

We consider the use of data reduction techniques for the problem of approximate query answering. We focus on applications for which accurate answers selective queries are required, and for which the data is very high dimensional (having hundreds or perhaps thousands of dimensions). We carefully examine the assumptions underlying many existing reduction techniques. To ensure both speed and accur...

Claude Bernard [1] was the first to point out clearly that the internal medium of living organisms is not merely a vehicle for carrying nourishment to cells but that "it is the fixity of the 'milieu interieur' which is the condition of free and independent life" (vol. 1, p. 404). W. B. Cannon [2] suggested the designation "homeostasis" for "the coordinated physiological processes which maintain...
