Practicing Professional Ethics in Engineering: How This Field is Developed and Its Importance

Many associations of engineers around the world have worked to develop rules in an effort to regulate the ethical practice of the engineer’s profession. These rules are usually referred as Code of Ethics for Engineers and tries to explain how an engineer must practice his work with professional ethics. The purpose of this paper is to show, in informative form, how this field has developed around the world and to emphasize the importance of implementing these rules during the practice of the profession of engineer

Formation of the Geometry of the Side Slopes from the Geotechnical Aspect for the Recultivation of the Degraded Area from Coal Mining

The impact of coal exploitation on the geological layers of the earth is closely related to mining activities and this activity has been quite pronounced considering the topographical changes of the green space together with the vegetation that would directly affect the degradation of agricultural lands. The soil is the environmental medium with irreparable damages from the activity of coal exploitation for the location where the Sibovc mine is located, which is characterized by the physical disappearance of the pedological profile of the soil such as the ecosystem, etc. and that represents the most serious form of damage to her. The purpose and importance of this paper is the biological recultivation of the area degraded by coal exploitation, based on the height of the scale H and the angle α° of the slope of the clay layers with the safety factor allowed for determining the humus layer for the cover of the degraded area, physical and chemical analyzes were performed based on the samples that were taken in the open profiles in the field, it was planned to plant saplings (trees) that will have a positive effect on the prevention of soil erosion, the enrichment of the air with O2, the reduction of the amount of CO2 in the air, the prevention of the distribution of dust in the environment, the size of the passage and from the geotechnical point of view, the prevention of humus soil landslides. The planned recultivation of the plot will start from the level of quota 570, 580 and 590 m, covering an area of about 17 hectares
