Plastic waste is a serious problem for the survival of all creatures on Earth. Recycling one solution to reduce negative impact environmental pollution caused by plastic waste. A lot that pollutes Earth comes from bottle (PET). There had been many studies discussed use (PET); however, this research used (PET) as geocell subgrade reinforcement. To date, still rare. The main purpose study was det...

the main problem of solid waste management system in tehran is to handle a large amount of waste (7.641 ton/day in 2008). therefore, source reduction can be introduced as one of the first priority for solid waste management in tehran. this research represents the first attempt to quantify the source reduction potential in the city, and subsequently, outlines the principle guidelines, legislatio...

The Plastic Waste phenomenon, which is the result of increasing poly (ethylene terephthalate) production and the wide range PET consumption in different industries, caused one of the major environmental concerns. Therefore,many different ways have been studied and applied for chemical recycling of PET. One of the most important ways to depolymerize poly (ethylene terephthalate) is the aminolysi...

This study has investigated the creep properties of asphaltic concrete modified with different dosages of waste polyethylene terephthalate (PET) in two different ranges of size. Uniaxial dynamic creep test at 40°C was conducted on the cylindrical specimens of the mixtures. The load was applied in two different frequencies of 0.5 and 5Hz. Creep test results showed that the accumulated strain und...

Surface modified electrospun polyester (PET) nanofibers with cyclodextrin polymer (CDP) were produced (PET/CDP). CDP formation onto electrospun PET nanofibers was achieved by polymerization between citric acid (CTR, crosslinking agent) and cyclodextrin (CD). Three different types of native CD (α-CD, β-CD and γ-CD) were used to form CDP. Water-insoluble crosslinked CDP coating was permanently ad...

Petroleum-based plastics have replaced many natural materials in their former applications. With their excellent properties, they have found widespread uses in almost every area of human life. However, the high recalcitrance of many synthetic plastics results in their long persistence in the environment, and the growing amount of plastic waste ending up in landfills and in the oceans has become...

A cyclotron named ARRONAX is being built in Nantes (France). It is mainly devoted to radiochemistry and nuclear medicine research and will be operational the last quarter of 2008. This machine will accelerate both protons and α-particles at high energy (up to 70MeV) and high intensity (2 simultaneous proton beams with intensity up to 350 μA). In nuclear medicine, these characteristics will allo...

Landfill sites are becoming over crowded and expensive for waste disposal, efforts are made to minimize the quantities of materials that are delivered to landfills. The threat due to leaching of non-biodegradable materials like waste plastics, scrap tyres. e-waste may contaminate the soil and ground water. If the production of waste cannot be prevented, then it is attractive to create an altern...

A 49-year-old male patient with a prior history of poor compliance with medical appointments was referred for an 18F-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) for the staging of a rectal squamous cell carcinoma. The PET/CT showed unilateral diffuse skeletal muscle 18F-FDG uptake as well as bilateral salivary gland uptake artifacts, suggestive o...
