The relationship between sustainability and business has become one of the central debates at the national and international level in both industrialized and emerging countries. A series of existing business models lack some critical aspects. The automotive industry strongly affects economic development, requiring rethinking business models in order to reduce their impact on the environment. An evaluation of the websites of the major automotive industry companies shows they have reported sustainability (through different methods) and present various practices in implementing organizational sustainability (OS). This paper aims to present a new business model for the automotive industry that takes into account the three dimensions of sustainability and emphasizes the importance of involving stakeholders in the OS approach. This model is developed based upon the literature review of three focus groups with a participation of 33 automotive industry members, of which three are highly-skilled experts of the industry. The proposed sustainable development model is scientifically relevant as it considers that all dimensions of sustainability exist and aims to increase organizational capacity for sustainable organizational development. It is also relevant from a practical point of view because it has been developed and validated by industry experts with automotive industry companies, taking into account the industrial, technical, and technological requirements for organizational sustainability assessment. The findings of this research will guide shareholders and managers in planning and developing organizational strategies.
This paper aims to study the behavior of air-gas explosion systems, in terms of propagation speed of pressure wave and flame front, based on experimental measurements in a shock tube, in order to prevent accidental pollution with the combustion gases. The characteristic parameters of the explosion process determined using the shock tube, the velocity of propagation of the flame front, the speed of propagation of the wave of pressure, explosion pressure at various distances from the source of initiation, can be used in the preparation of explosion risk assessment studies for technological processes carried out in potentially explosive atmospheres. Taking the developed technical measures would make possible ensure both the explosion protection and the prevention of accidental pollution with combustion gases.
Analysis of main environmental components must be appropriate and useful for establishing decision-making elements regarding environment quality, the need for intervention and remediation in major cases, or improvements and development forecasting for local specific situations or subsequent climatic behaviour and composition transformation processes. In this respect, the usefulness of the information gathered from environmental analysis largely depends on how monitoring actions and environmental analysis (inspection and measurement) are planned. Pollutants discharged from use of various technological gases must be measured and analysed to avoid potential hazards and protect vital space and man against direct and indirect effects of noxae. To this end, the current paper aims to analyze certain internationally recommended methods for measuring and monitoring main gases which have negative impact upon the environment and human health, such as physicochemical analysis/evaluation/radiography of gases and dusts from the Jiu Valley urban area's atmosphere, trying to asses the state of the environment in this area.
The manner in which individuals deal with stressful situations depends on several variables. Personality characteristics, event circumstances, preparedness of individual, personal appraisal of events, pre-existing organizational and personal stressors are all key factors. Psychological resistance to stress can be the result of spontaneous evolution, or can be developed through special training, through programs that increase the threshold beyond which functional alterations may occur, resulting from dealing with stressful events. Psychological training can be improved by acquiring specific psychological knowledge and strategies and by indirect experiences with emergency situations and scenarios. Procedures such as stress inoculation, emotional management and stress reduction management, cognitive restructuring, relaxation techniques, problem solving and optimization of interpersonal relationships can be learned and used by individuals. Along with training in conditions as close as possible to future reality of interventions, psychological training can contribute both to the success of intervention and rescue operations and to appropriate management of emotions generated by emergency response. The current paper details issues regarding the implementation of a psychological training program for intervention and rescue personnel in toxic/ flammable/ explosive environments, in order to test it and to identify adjustments needed to be made for optimizing it, as well as a series of theoretical fundaments for each of the five modules of the program.
Intervention and rescue activities require knowledge of the real situation in the affected area as accurately as possible. Therefore, the physical exploration of this area is at the same time necessary and risky. The use of drones from a safe distance can protect the intervention team from exposure to unknown hazards. Endowment of the drone with a suite of sensors such as high resolution cameras, thermal imaging, infrared, and gas detection equipment permits vital data to be transmitted to the base of intervention. Hazardous areas can be studied from different angles, from an altitude that provides a panoramic view, and make available rescuers information about dangers encountered, state of access routes, number of people caught by the event, and control or protective measures that need to be taken. The current paper presents the methods for use and control of drones in support of rescue actions, resulting from tests performed by the research team, trained and certified to use drones, within the National Institute for Research and Development in Mine Safety and Protection to Explosion-NIRD INSEMEX. It was demonstrated that a drone which carries a multigas detector and a high definition video camera can help rescuers which intervene in an area with fire/toxic/flammable hazard. For such a mission, a drone must be capable to flight a long time, to carry the multigas detector and to flight secure without visual contact and without autonomous flight support in case of GPS signal lack. Flights in such conditions impose high power engines with 6-8 propellers for fine adjustments.
