Badanie zostało przeprowadzone na Uniwersytecie w Tikrit / College of Science / Wydział Biologii / Laboratorium Środowiskowe, od września 2013 do czerwca 2014. Badanie koncentruje się na rurach ze stali węglowej. Próbki gleby zostały pobrane z trzech różnych regionów: gleba 1: piasek gliniasty, gleba 2: glina piaszczysta i gleba 3: piasek, te trzy próbki zostały pobrane z głębokości 0-50 cm. Korozja podziemnych rur staje się poważnym problemem zarówno w zakładach chemicznych, jak i użyteczności publicznej, dlatego w celu wyeliminowania korozji zastosowano ochronę katodową, tekstura gleby ma znaczący wpływ na szybkość korozji, najwyższa wartość korozji wynosiła (13,637%) w glebie 2, podczas gdy najniższa wartość wynosiła (9,383%) w glebie 3. Ochrona katodowa ma znaczący wpływ na zmniejszenie szybkości korozji, podczas gdy korozja rury chronionej wynosiła (1,462%), podczas gdy korozja rury zakopanej w tych samych warunkach, ale bez ochrony wynosiła (11,267%). Pseudomonas aeruginosa, Enterobacter cloacae i Staphylococcus aureus, te trzy rodzaje bakterii utleniają żelazo, co oznacza, że jest ono korozyjne. Odkrycia te mogą silnie sugerować, że bakterie utleniające żelazo są rzeczywiście bardzo korozyjne.

    Ana Isabel Pereira Cardoso / Teresinha M. Gonçalves
    Life in cities has distanced human beings from nature and made it difficult to understand the ecology of life dependent on the environment. Urban water collection and distribution processes contribute significantly to the fragmentation of knowledge and the vital recognition of the water cycle. Without the effective participation of the subject in environmental actions, it is no...

    Bret C. Harvey / Steven F. Railsback
    Ecologists now recognize that the dynamics of populations, communities, and ecosystems are strongly affected by adaptive individual behaviors. Yet until now, we have lacked effective and flexible methods for modeling such dynamics. Traditional ecological models become impractical with the inclusion of behavior, and the optimization approaches of behavioral ecology cannot be use...

    Carlos Martínez del Rio / William H. Karasov
    Unlocking the puzzle of how animals behave and how they interact with their environments is impossible without understanding the physiological processes that determine their use of food resources. But long overdue is a user-friendly introduction to the subject that systematically bridges the gap between physiology and ecology. Ecologists--for whom such knowledge can help clarif...
