“…The building materials and the construction industry is trying to accomplish the durable development criterions byproducts using, in order to reduce to minim the impact on the environment [1,2]. The concrete is a widely utilized in construction, presenting a great durability potential, taking into account that it can be combined with different types of byproducts, such as fly ash, silica or furnace slag.…”

The study was conducted in the Laboratories of the Faculty of Civil engineering and Building Services, department of Concrete, Materials, Technology and Management, Technical University “Gheorghe Asachi” from Iassy. The main objective of the experimental research from this paper is the analysis of some types of concretes prepared with polystyrene granules and fly ash, aiming to obtain a material which is corresponding to the structural requirements, to be energetically efficient and to be ecological. Using these components, the durability characteristics (frost - thaw and corrosion), the influence of the polystyrene granules on the environment and the mode in which the materials properties are maintained in time under environmental factors, were experimentally determined. The concretes were prepared with polystyrene granules and fly ash from CET Holboca Iassy, Romania. The fly ash was utilized in proportion of 10% and 20% from the cement amount and the polystyrene granules replaced some sorts of the natural aggregate. The types of concretes are CPOL1, CPOL2, CPOL3 and CPOL4.

“…In order to use the wastes in polymeric patching and grouting materials, and especially in coatings to improve the environmental aspects of its production, natural river and crushed fine aggregate, sand, and quartz flour can be replaced in different percentages by natural waste or sub-products, such as silica fume, milled recycle glass, fly ash, polystyrene granules, saw dust, polyethylene terephthalate (PET) particle, etc. [14][15][16][17][18][19][20].…”

Impact of Aggressive Media on the Properties of Polymeric Coatings with Solidification Products as Fillers

Dealing with waste materials, particularly hazardous waste, is a serious problem. Disposal areas keep growing, and the costs incurred are high. Disposing of such waste reduces negative environmental impacts and offers considerable financial savings. This paper focuses on the possibilities of incorporating pollutants found in hazardous wastes as fillers in coatings based on polymers (epoxide and polyurethane). These coatings are intended mainly for concrete and metal bases and offer secondary protection against adverse weather conditions. Important physical and mechanical properties of the newly developed materials were determined; they include surface hardness, impact resistance, tensile properties, and chemical resistance. These properties were also compared to those of the reference filler. At the same time, the influence of aggressive media on the properties of these materials was observed, in particular on flexural characteristics. The microstructures of the developed coatings were tested using a high-resolution optical microscope, before and after exposure to the chemicals. The positive effect of using progressive fillers, such as solidified hazardous waste (a solidification product (SF)), was witnessed by their constructive contribution to the materials’ physical and mechanical properties. The use of solidification products is unambiguously advantageous from technical, ecological, and economical stand points (utilization of hazardous waste as a progressive filler instead of landfilling, improvement of tensile properties, reduction in the price of coating system, and incorporation of the pollutants into the polymer matrix).

“…As far as surgical techniques are concerned, videoassisted thoracoscopy comes with lot of improved results compared to classical surgical technique [5]. This technique seems to reduce the parameters reflecting the period of hospitalization, exposure to analgesics, patient's recovery rate, and the level of pain felt [6,7].…”

As far as surgical techniques are concerned, video-assisted thoracoscopy comes with lot of improved results compared to classical surgical techniques. This technique seems to reduce the parameters reflecting the period of hospitalization, exposure to analgesics, patient�s recovery rate, and the level of pain felt. Studies have been conducted that have demonstrated that, hypnosis can significantly improve the duration of pain exposure as well as the intensity perceived by the patient. In domain literature report cases in which hypnosis has been proven effective is in the preoperative preparation of surgical patients. furthermore, by applying hypnosis, positive results are found during the postoperative care of patients. This study aims at the results of video-assisted surgical techniques, and at the opportunity of integrating complementary therapeutic elements such as hypnosis to improve the parameters interested in perioperative care of the surgical patient.
