Abundant cytoplasmic proteins pulse-labeled with [35S]methionine at specific times throughout the HeLa cell cycle were analyzed with two-dimensional gel electrophoresis. More than 300 proteins could be resolved in this way. The frequency of appearance of label in the most abundant 90 proteins, ranging from 4% to less than 0.1% of the total methionine incorporated, was determined at six time poi...

Variations in total heart volume (atria plus ventricles) during a cardiac cycle affect efficiency of cardiac pumping. The goals of this study were to confirm the presence, extent, and contributors of total heart volume variation during the cardiac cycle in healthy volunteers with the use of MRI. Eight healthy volunteers were examined by MRI at rest. Changes in total cardiac volume throughout th...

For the 27-year period 1933-1959 inclusive, highly significant negative correlation is found between the relative sunspot number and the worldwide average of total atmospheric ozone. Peak correlation with respect to the present-day 10-year sunspot cycle is found at a lag of 1•/• to 2 years of the sunspots relative to ozone. The peak correlation of total atmospheric ozone with the mean latitudin...

abstractaccidents and natural disasters and crises coming out of them indicate the importance of an integrated planning to reduce their effected. therefore, disaster relief logistics is one of the main activities in disaster management. in this paper, we study the response phase of the disaster management cycle and a bi-objective model has been developed for relief chain logistic in uncertainty...

We deal with the Hoist Scheduling Problem, where a hoist carrying products along a production line must be scheduled. Products are taken from a bath once finished an operation and moved to the following one. There are time windows (a minimum and a maximum values) for the time spend at each treatment. The objective is to minimise the total production time. Our contribution is the use of bounds o...
