Abstract: Forests provide plenty of fundamental tangible and intangible goods to our planet, from vital chemical substances (O2 ) to more economic issues (wood for economic activity and heating etc.). Hence, besides the ecological role of forest fires at our ecosystems, an efficient prevention strategy for confronting recurrent and destructive fires is considered of crucial importance. Primary objective of the paper is the estimation of fire hazard in Thasos island taken into consideration all the factors which are conducive to forest fires ignition and spreading. The pillar of the methodology lies in the fact that a unique fire risk map will be created based on the local characteristics, namely, topography (aspect and slope); fuels characteristics and the proximity from the road and urban network. Taking into account the individual contribution to the overall fire hazard of all these factors, we developed a model for estimating the fire hazard of any given area, overlapping all the essential thematic maps. We identified some critical areas which are characterized very susceptible and they situated in the interior and the western part of the study area, where mixed and very flammable fuels take place along with steep ground and south aspect. This project may be quite applicable to any territory, adjusted to the local differences and peculiarities. The importance of such a project is prominent, while it constitutes a project with great added value, least cost and if it may be combined with other supporting activities to maximize the forest fires prevention and safeguarding the cultural and ecological wealth.
Keywords: Chemical synthesis, PEG, TEM, BMP model.

Abstract: Pristine and Co doped SnO₂ nanoparticles were synthesized in aqueous solution by facile chemical co-precipitation method with polyethylene glycol (PEG) as a capping agent. The as prepared samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), Fourier transform infrared (FTIR) spectra and vibrating sample magnetometer (VSM). XRD patterns revealed that particles of all samples were crystallized in single phase rutile type tetragonal crystal structure (P4₂/mnm) of SnO₂ . TEM images indicated spherical shape of nanoparticles with a size ranging from 25-35 nm. FTIR spectra suggested that the PEG simply coexisted with the SnO₂ surface nanoparticles and inhibited the agglomeration of the nanoparticles. Magnetization measurements revealed that all the Co doped SnO₂ nanoparticles exhibited ferromagnetic signal which became stronger with increasing Co content. Variation of ferromagnetic order with Co content from vibration sample magnetometer is endorsed to the anti-ferromagnetic (AFM) interactions among the magnetic ions as anticipated by the bound magnetic polarons (BMP) theory.
Keywords: Chemical synthesis, PEG, TEM, BMP model.

Abstract: Nano-materials such as nanosilica (NS), nano-calcium hydroxide {Ca(OH)₂}, and nano-aluminum hydroxide {Al(OH)₃} have been synthesized using a suitable method. In addition, gypsum has been prepared by precipitation method. The as prepared nano materials are characterized using x-ray diffraction (XRD), transmission electron microscopy. The average particle sizes are 15 nm, 49 nm and 25 for NS, Ca(OH)₂ and Al(OH)₃ , respectively. These nano-materials are mixed with gypsum in a stoichiometric ratio to form ettringite as well as monosulphate mixes. NS was added to these mixes and hydrated at room temperature up to 28 days. All hydrated samples were characterized by performing chemical methods, XRD, differential thermal analysis, and thermal gravimetric analysis techniques. It was found that, the disappearance of Ca(OH)₂ due to its consumption during the reaction with NS stabilizes ettringite formation.
Keywords: Etrringite, ettringite+NS, hydration time, characterization techniques.

Abstract: Many transportation agencies in North America and Egypt have reported that stripping can be a significant issue in most pavement distresses such as rutting, fatigue cracking, ravelling, potholes, and flushing. In addition, Canadian airfield asphalt concrete pavements, especially in the Atlantic, Central, and Pacific regions, show evidence of stripping due to moisture susceptibility. It is recognized that density and in-place air-void content (AVC) are important parameters of a properly constructed asphalt pavement. The first objective of this research was to investigate different factors that may affect stripping evaluation. During the development stage samples representing four Canadian airfield mixes were prepared and tested to investigate the effect of soaking duration, air voids content, and soaking temperature. The results of the air-void investigation, which were compatible with the concept of Pessimum theory, showed that samples should be prepared with an air-void content of more than 8.5%, with a soaking duration of 6 to 8 hours and soaking temperature of 70 °C. The second objective of this research is to validate the developed criteria of stripping prediction on Egyptian mixes. The validation was carried out using Egyptian mixes with five different anti-stripping agents and it showed that the developed stripping evaluation guidelines has the ability to predict the effect of anti-stripping agents on the retained tensile strength of the examined mixes.
Keywords: Asphalt Mixtures, Evaluation, Field, Laboratory, Stripping, Testing Procedures.

Abstract: Recycling asphalt pavement creates a cycle of reusing materials that optimizes the use of natural resources. Reclaimed asphalt pavement (RAP) is a useful alternative to virgin materials because it reduces the need to use virgin aggregate.[1] In this investigation, it has been studied the effect of nano material such as nano silica and nano carbon on the mechanical properties of marshall specimen. Tests were carried out on cold RAP with slow setting emulsion. Optimum percent of emulsion was obtained from previous research. After determination the optimum percent of nano silica and nano carbon tubes , these percent used with optimum percent of latex to studding the improvement in mechanical properties. The results showed that, there is improvement in stability about 150% by used nano materials.
