During the vase life of cut stems obstruction of xylem vessels occurs due to microbial growth, formation of tyloses, deposition of materials in the lumen of xylem vessels and the presence of air emboli in the vascular system. Such obstructions may restrict water uptake and its transport towards upwards thus lowering their ornamental value and longevity of cut flowers. Clematis is a very attract...

It is rigorously shown that the fluctuation formula, which is used in simulations to calculate the dielectric constant of interaction site models, corresponds to the reaction field with an individual site cut-off rather than with the usual molecular center of mass truncation. Within the molecular cut-off scheme, a modified reaction field is proposed. An influence of the truncation effects is di...

We hypothesized that residents of Woburn, Massachusetts, had been exposed to as much as 70 microg/l of arsenic (As) and 240 microg/l of chromium (Cr) in drinking water from municipal supply wells G and H. To test this hypothesis, we measured the concentrations of As and Cr in 82 hair samples donated by 56 Woburn residents. Thirty-six samples were cut between 1964 and 1979, the period during whi...

This study was carried out to investigate the effect of differentpreservative solutions to improve the keeping quality of tuberose (Polianthes tuberosa cv. Single). These preservative solutions (treatments) were: T1= 2% sucrose + 200 mg/l AgNO3, T2= 2% sucrose + 200 mg/l AgNO3 + 25 mg/l citric acid, T3= 2% sucrose + 300 mg/l HQS, T4 = 2% sucrose + 300 mg/l HQS+ 25 mg/l citric acid, T5= 2% sucro...
