  • A major challenge in clinical periodontics is to find a reliable molecular marker of periodontal support loss with high sensitivity, specificity and utility (Buduneli & Kinane 2011). Molecules derived from inflamed host tissue and pathogenic bacteria have the potential of being used as markers of periodontitis; however, molecular markers of bone resorption have advantages as they relate to specificity for bone, easy detection, pre-analytic stability and availability of sensitive and specific assays for detection (Forde et al. 2006).

  • For the earthquake motion level 1, the elastic limit the value of a structure is usually adopted seismic activity. For Level 2 earthquake motion, on the other hand, the limit value that a structure does not collapse or repair through the seismic activity depends on the importance of intended structure. Level 2 earthquake motions are used for verification is based on the records of strong motion seismograms obtained from the Hyogoken Nanbu earthquake and the other, and seismic waveform types are assigned according to the ground....

  • In order to evaluate the status of damage caused by the stresses on the plants growing process before visible damage is noticed, we have followed the evolution of the Chl content in the plant leaves using the Fr/FFr chlorophyll fluorescence ratio. The absolute emission signal of leaves can vary from sample to sample due to small differences such as excitation and sensing angles of the fluorescence, and the roughness and scattering properties of the leaf surface. Thus, the absolute fluorescence usually varies to a large extent than the fluorescence ratio.

  • Laboratory tables function as student workstations. School classrooms and science laboratories must provide each student with a workstation. Laboratory tables can accommodate 2–4 student workstations per table. The purchase of laboratory tables is a major expense for a school districts; therefore, tables should be well-constructed and maintained to support optimal student performance in the laboratory. The Scientific Equipment and Furniture Association (SEFA) has developed a list of performance properties for laboratory tables work surfaces. These properties are shown in Table 3.

  • This desk study was financed by the EUROPEAN COMMISSION, Joint Research Centre, Ispra. It gives an overview of the occurrence of these organic compounds in sewage sludge, basic toxicological data, a review on persistence of organic contaminants in soils and risk assessments for the various pathways. The attempt was made to identifiy additional substances or substance groups which might cause hazards and should be regulated. Thus it is recommendended that the benzo(a)pyrene concentration in soil is regulated.

  • It may seem strange to lump what is supposed to be a way to save the planet Earth with mindsets that prevent environmental progress. Obviously, not all goals of sustainable development act as barriers, but some ideas of this concept simply miss the mark. The Brundtland report, the basis of the Rio Earth Summit in 1992, called on governments to redefine economic activity to become sustainable. The report defines this as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

  • Mercury that exists in a stable state in the Earth’s crust is referred to as “geologic” mercury. The active mercury cycle begins when mercury is released from this stable form to the environment through natural processes or human intervention. There are four principal pathways releasing mercury to the environment. First is through natural processes; for example, mercury that was once in the Earth’s crust could be released through a volcanic eruption or other geological activity.

  • Today it is Moscow that sets the pace for EU-Russia relations. The soaring prices of gas and oil have made energy-rich Russia more powerful, less cooperative and more intransigent. Oil money has boosted the state budget and has dramatically decreased the Russian state’s dependence on foreign funding. Russia’s hard currency reserves are the third largest in the world today; the country is running a huge current account surplus and paying off the last of the debts accumulated in the early 1990s.
