Iron deficiency in early development has been associated with irreversible alterations in brain myelination, but whether these neural changes are mirrored in altered behaviors in rats is not known. The goals were to determine if dietary induced gestational and lactational iron deficiency alters brain myelination and behaviors dependent on that system.(More)
In cyberspace, the emergence and increasing importance of search engine prompts numerous evaluation studies in regard to its effectiveness. Based on a user-oriented perspective, the paper is aimed to derive functional requirements of search engines rooted in Herzberg's Two Factor Theory. A survey, with 758 valid participants, was conducted to investigate(More)
