Experiments Regarding Thermal and Mechanical Deformations of Continuous Cast Steel Wire

During the casting process, the crust of the steel wire is permanently subjected to thermo mechanical stresses (temperature variations, pulling, bending and straightening forces, ferrostatic pressure), which, when exceeding the deformation capacity of the crust, can lead to cracks. Therefore, it is necessary to know what kind of stresses act on the crust and how the steel behaves at high temperatures at certain process parameters (extraction speed, cooling intensity, etc.)

Experiments Regarding the Fabrication of the Higher Strength Steels Plates

The normalizing of ferritic-pearlitic steels is a heat treatment, which consist of reheating into the austenite and subsequent air-cooling. For greater thickness, e.g. 100 mm, variations in the requirements may be permitted or required for particular applications but a reduction of the required impact energy is not allowed. The most important cote of the cost can be eliminated if the process normalizing rolling is applied

Contributions to Increasing the Quality of Urban Life Through the Use of an Intelligent Road Traffic Management System

Traffic congestion is a phenomenon which occurs when road traffic is disturbed. In Galati city, traffic congestion increases rapidly due to an increase in the number of vehicles on the road. This work is an attempt to analyze the effects of traffic congestion by applying the waiting theory. Traffic congestion is frequent during the day, and the locals accept it as a daily routine. Urbanization in developing countries indicates that more people live in cities than before. The trend of urbanization, the population growth and the increasing number of registered vehicles put pressure on traffic and make life in the urban area more difficult. General data congestion and congestion management are the mitigation measures proposed but they are labor intensive and a heavy investment would be needed. Therefore, in order to find feasible measures, latest technologies such as GIS and GPS help analyze the live traffic situation and suggest cost effective measures to alleviate congestion. A previous attempt was effective in data collection, data analysis and display of results [1, 2]. A Geographic Information System (GIS) is a computer-based mapping tool that geographically analyses events and phenomena occurring on Earth. GIS technology integrates common database operations such as query and statistical analysis with unique viewing and the benefits of geographic analysis provided by maps [2]. In Galati, the GIS system is still not applicable because it has not been purchased by the competent authorities. In Romania, the GIS system is partially implemented. The traffic congestion has begun to be solved globally through GPS positioning technology with vehicle data collection, transport and operation. Using GPS Vehicle will provide direct and objective data on the behavior and status of the trip and the transport system that influences this behavior [3]

Uterine Artery Embolization for Uncontrollable Hemorrhage after Vaginal Hysterectomy

Hysterectomy is the most common gynecologic procedure performed all over the world and various complications may appear depending on the surgical route. Delayed postoperative hemorrhage is a rare, life threatening complication. It requires timely management and recently the surgical reinterventions tend to be replaced by minimally invasive techniques. Transcatheter arterial embolization shows good results as a treatment strategy for massive vaginal bleeding post hysterectomy, when vaginal vault suturing fails to achieve hemostasis. We report a case of right uterine artery bleeding occurring 30 days after vaginal hysterectomy that was successfully treated by transcatheter arterial embolization
