Ergonomics: Requirements for Adjusting the Height of Laparoscopic Operating Tables
BACKGROUND AND OBJECTIVES In the last few years many new instruments and devices have been developed and introduced into the operating room (OR). A debate has been ongoing about the optimal ergonomic posture for the operating staff. From practical experience, we have learned that the operating tables cannot be adjusted adequately to allow surgeons of different stature to maintain a comfortable ...
متن کاملThe Assessment of Bandwidth Requirements for Meteorological Code VARSHA on a Parallel Computing System
Complex scientific problems like weather forecasting, computational fluid and combustion dynamics, computational drug design etc. essentially require large scale computational resources in order to obtain solution to the equations governing them. These solutions are obtained by developing large legacy codes and then executing them using parallel processing systems as they require large scale co...
متن کاملMeteorological input data requirements to predict cross-pollination of GMO maize with Lagrangian approaches.
Modeling pollen dispersal to predict cross-pollination is of great importance for the ongoing discussion of adventitious presence of genetically modified material in food and feed. Two different modeling approaches for pollen dispersal were used to simulate two years of data for the rate of cross-pollination of non-GM maize (Zea mays (L.)) fields by pollen from a central 1 ha transgenic field. ...
متن کاملThe effect of meteorological drought on vegetation dynamics in Iran
Drought as a complex ecosystem crisis can affect vegetation density and health. Iran with an arid and semi-arid climate is exposed to this phenomenon. Therefore, it is necessary to evaluate the effect of drought on vegetation. The purpose of this study is to evaluate the effect of meteorological drought on vegetation dynamics in Iran. In this regard, using MATLAB software, SPEI index with time ...
