Colourless needle-shaped crystals of the title compound, (C(26)H(21)BrOP)(2)[Hg(2)Br(6)], have been prepared by addition of a solution of HgBr(2) in methanol to a solution of (4-bromo-benzoyl-meth-yl)triphenyl-phospho-rane in dry methanol. The compound features Hg(2)Br(6) (2-) dianions, whose site symmetry is .

A detailed study using the cyclic voltammogram was done on the live cells of Aspergillus terreus. The peak current values were obtained for different days of growth and plotted against time. The response of cyclic voltammogram showed the phases of the growth of the fungus. The growth curve obtained matched well with the conventional methodology, which assesses the increase of dry weight of the ...

We are all far more concerned with our appearance than we’d probably like to admit. It’s not vanity. Vanity implies pride. No, we’re concerned. Concerned we’re too thin or overweight. Concerned our hair is too fizzy, too greasy, or that it never sits right. We’re concerned about pimples, blackheads, dry or oily skin. Our clothes aren’t flattering. There’s always someone who looks better than we...

We designed an artificial one-dimensional DNA nanotrack that contains two T-motifs. It can be fabricated in a free solution and with a mica-assisted growth process. Also, we introduced a dry and wet method for the restoration of DNA nanostructures in order for them to be used in multiple applications.

Solid carbon dioxide exhibits a rich phase diagram at high pressures. Metastable phase III is formed by compressing dry ice above ∼10-12 GPa. Phase VII occurs at similar pressures but higher temperatures, and its stability region is disconnected from III on the phase diagram. Comparison of large-basis-set quasi-harmonic second-order Møller-Plesset perturbation theory calculations and experiment...

Introduction Conclusions References

PURPOSE To investigate whether exposure to occupational levels of organic solvents in the dry cleaning industry is associated with neurotoxic symptoms and visual deficits in the perception of basic visual features such as luminance contrast and colour, higher level processing of global motion and form (Experiment 1), and cognitive function as measured in a visual search task (Experiment 2). M...

In Armenia, Nymphaea alba only occurs in a small area NW of Stepanavan. It is restricted to small lakes with a minimum depth of c. 2–3 m because in shallower lakes it may be out-competed by Typha or Schoenoplectus species.

D ry eye is very common among patients presenting for cataract or laser vision correction surgery. If the dry eye is not treated preoperatively, it can reduce the quality of preoperative data and can have a negative impact on surgical outcomes. Just prior to ASCRS, we surveyed cataract and refractive surgeons about the incidence of dry eye in their surgical patients, their awareness of current ...

BACKGROUND There is an increasing body of evidence strongly suggesting that glaucoma medications may contribute to ocular surface disease and development of dry eye. OBJECTIVE To identify glaucoma patients with dry eye, using a nationally representative sample, and to compare clinical and treatment characteristics with controls without dry eye. METHODS Patients taking intraocular pressure-l...
