  2. 1. Fluoride concentration in plaque and saliva and its effects on oral ecology after intake of fluoridated milk

    Author : Kristina Engström; Svante Twetman; Lars G Petersson; Göran Dahllöf; Umeå universitet; []
    Keywords : children; enamel; demineralisation; fluoride; lactic acid; laser fluoroscense; milk; plaque; saliva; salivary bacteria; odontologi; Odontology;

    Abstract : According to WHO, the addition of fluoride to milk could be considered as an alternative to water fluoridation for community-based caries prevention in childhood. School-based schemes in developing as well as industrial countries have demonstrated substantial benefits on oral health, but there are limited data available on the local events in the oral cavity after consumption of fluoridated milk.

  4. 2. Towards sustainable solid waste management in Jordan

    Author : Mohammad Aljaradin; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Solid Waste Management; Public Participation; Recycling; Landfilling; Jordan;

    Abstract : Jordan is a country with a growing population that is undergoing rapid modernization. The increased volume of solid waste and associated logistical difficulties, the steady growth in the cost of waste management and the risk to human health are sources of concern. READ MORE

  5. 3. Structure, interactions and functionality in novel electrolyte materials for fuel cell applications

    Author : Anna Martinelli; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; proton conductivity; ionic liquids; Polymer electrolyte membrane PEM ; fuel cell; vibrational spectroscopy;

    Abstract : It is today well known that fossil fuels will sooner or later be depleted, and the need to find alternative energy sources is now accepted. Among the diverse technologies developed to produce energy, considerable interest is currently directed to the hydrogen fuel cell, a device that converts chemical into electrical energy, is versatile and has a low environmental impact.
