This study assesses the environmental performance in end-of-life (EoL) of double walls made carbon-reinforced concrete (CRC) and steel-reinforced (SRC). The most feasible CRC EoL scenarios are evaluated using life cycle assessment their performances then compared to those SRC. results showed that mechanical recycling is best scenario, with a global warming potential (GWP) 7.0 kg CO2 eq., while ...

Efficacy of combined acid-heat treatments to protect crude protein (CP) against ruminal degradation has not been extensively researched. Four in vitro trials (Daisy technology) with orthophosphoric and malic acids were performed to examine effects on protection of sunflower meal protein. In Trial 1, effects of the solution volume for adding two doses of orthophosphoric acid (0.4 and 1.2 eq/kg s...

Introduction: Greenhouse gas (GHG) emissions have caused environmental effects. Food production is one of the sources of GHGs. This study aimed to suggest dietary scenarios for decreasing GHG emissions. Materials and Methods: GHG emissions in the target population of Urmia city, Northwest Iran, were investigated using a modeling approach. Three dietary scenarios were modeled and analyzed to ev...

Diverse opportunities and environmental impacts could occur from a potential move towards waste-to-energy (WtE) systems for electricity generation municipal solid waste (MSW) in Lagos Abuja, Nigeria. Given this, the purpose of this study is to use life cycle assessment (LCA) as primary analytical approach order undertake comparative analysis an impact perspective different WtE scenarios, along ...

to determine effects of phenyl-phethalamate acid on yield and yield components of tomato, cucumber, eggplant and cabbage, this experiment was investigated in a randomized complete block design with three replications in the spring and summer of 2010. treatments included the time and number of foliar spraying with phenyl-phethalamate acid (1000 ppm). control plants were not sprayed. the first st...

carotenoids are the main pigments of tomato, of which 93% is lycopene. lycopene has desirable physiological effects in human sush as cancer prevention. recent years, because of harmful side effects of synthetic colouring agents used in food products, employing of natural food colouring agents has become very important. in this research firstly, solvent extraction method was used for tomato caro...

Background: Aflatoxin B1 is a secondary toxic metabolite produced by several aspergillus species. This study was conducted to determine the presence of aflatoxin in tomato paste samples. Methods: A total of 30 tomato pastes were analyzed for Aflatoxin B1 contamination via HPLC-FLD. Analyte extraction was done by dispersive liquid-liquid microextraction. Results: The limit of detection (LOD) and...

introduction: mycorrhizal symbiosis is one of the most popular and highest symbiotic relationship in plant kingdom. most plants (about 80% of vascular plant species) have at least one type of mycorrhiza. arbuscular mycorrhizal fungies are the most important endomycorhiza fungi that play an important role in agriculture. materials and methods: in order to evaluate the effect of arbuscular mycorr...
