  1. 1. Experimental studies on effects of orthodontic forces in generation of immune responses : Possible roles for immunoregulating molecules in the control of alveolar bone remodeling

    Author : Najat AL-Sayed AL-Hashimi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Orthodontic forces; inflammation; immune responses; cytokines; chemokines.;

    Abstract : The transformation of orthodontic forces to periodontal tissues involves several biological mechanisms, which ultimately result in bone remodelling. It has been suggested that the immune system plays a role in the regulation of bone remodelling through production of immune mediators by inflammatory cells that have migrated from dilated periodontal ligament capillaries after the application of orthodontic force.

    Abstract : Artificial intelligence (AI) is one of the fields in science and engineering and encompasses a wide variety of subfields, ranging from general areas (learning and perception) to specific topics, such as mathematical theorems. AI and, specifically, multi-objective genetic algorithms (MOGAs) for risk-based life cycle cost (LCC) analysis should be performed to estimate the optimal replacement time of tunnel fan systems, with a view towards reducing the ownership cost and the risk cost and increasing company profitability from an economic point of view.

  3. 3. Potential Use of Aquifer Thermal Energy Storage System in Arid Regions

    Author : Qais Al-Madhlom; Jan Laue; Nadhir Al-Ansari; Sabbar Abdullah Saleh; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer thermal energy storage system; ATES; site selection; seepage velocity; aquifer vulnerability; DRASTIC; arid regions; ArcMap GIS.; Geoteknik; Soil Mechanics;

    Abstract : After the Oil Crises in 1973, which meant higher energy costs, the world started to look for other sources of energy. This led to the development of renewable energy techniques. Because of the intermittent nature of renewable energy, storage systems were also developed. READ MORE

  4. 4. Team-based approach in the management of diabetes at primary health care level in Muscat, Oman : challenges and opportunities

    Author : Kamila Al-Alawi; Helene Johansson; Ahmed Al Mandhari; Lars Lindholm; Charli Eriksson; Umeå universitet; []

    Abstract : Introduction: The growth of type 2 diabetes is considered an alarming epidemic in Oman. The efficient team-based approach to diabetes management in primary health care is an essential component for providing ideal diabetic care. READ MORE

  5. 5. Soil Modification by adding small amounts of binders : A laboratory study

    Author : Wathiq Jasim Al-Jabban; Jan Laue; Sven Knutsson; Nadhir Al-Ansari; Paolo Simonini; Luleå tekniska universitet; []

    Abstract : Soil stabilization through addition of a hydraulic binder is a method frequently used to modify and improve engineering properties of soft soils. Additives like cement and lime are typically used as stabilizers. More recently, industrial by-products, such as fly ashes, cement kiln dust, blast furnace slags and other slags have been used.
