  • The biologic phenotype underlying chronic periodontitis, including the biofilm and the host response, tend to vary among individuals despite a similar clinical diagnostic category (Offenbacher et al. 2007). Consequently, disease screening should ideally be based on clinical determinations and the biologic phenotype (Page and Kornman 1997). Other associated factors include environmental exposures, as well as differences in genetic and possibly epigenetic composition (Page and Kornman 1997).

  • The objective of waste water treatment is to prevent large quantities of substances to reach and impact the environment in high doses and concentrations. Areas of high population densitiy naturally are areas were production of sewage sludge is high (see Figure 1-1). Presently about 8 million t of sewage sludges (MAGOAROU 2000) are produced each year in the EU member states (Table 1-1). Its high content of organic materials, of nitrogen and phosphorous suggest their use as soil conditioner and fertilizer in agriculture.

  • Calculation of disposal costs may involve a set of tasks. It may be necessary to calculate material flows (an engineering exercise) from the plant's production process so that wastes can be desegregated and tracked. These material flows will then have to be translated into disposal costs. This calculation can be complex. Consider the issues that arise if the waste is destined for landfill disposal. First, there will be marginal disposal costs associated with transport of the waste. Second, the waste's contribution to landfill costs must be calculated.

  • Two other papers focus specifically on building sovereign debt datasets. Jeanne and Guscina (2006) collected data on emerging economy public debt, with details on the jurisdiction of issuance, maturity, currency, and indexation. The data cover 19 emerging economies during 1980–2002 and were compiled mainly from official publications, supplemented by information from questionnaires to country authorities and IMF data.

  • Really, they don’t. No one is going to ask for your transcript when hiring you for a position at a university or research institution. They are going to carefully check your ideas, your research, and your teaching experience. That’s all there is to it. But one cannot do frontier research if one doesn’t know what the frontier is! And for that, the material you learn in the first year is important. Take your time to learn it properly. You’ll see that it more than makes up in the...

  • Many of the Earth’s elements travel or cycle through the natural environment. This means that they are transported from the soil into nearby lakes and rivers, and then evaporate from the water into the air, to be transported by wind and eventually re-deposited to the surface where the cycle starts over again. Mercury cycles through the environment in this way (see Figure 5). An atom of mercury may begin its journey by being eroded from rocks on the shore of a lake or by being vented into the atmosphere as mercury vapour from a volcanic eruption. These are natural emissions.

  • Today, nano composite material is being studied and widely used for defence security and economic development. Keeping researching on the mechanic of three-phases nano composite in which two-phases is grains of pad and the structure of one-phase in reinforced two-phases is a nano structure, basing on consideration for interaction of the polyme matrix and grains of padding, we have defined engineering constants of the three-phases polyme composite nano material.

  • Defining the various tasks required of GDHit was essential before any visual brainstorming was approached. These tasks, once defined, helped clarify perceptions of layout and functionality. The main function of the timeline is to search content chronologically (span a set number of years), filter content (through the classification of various categories), read content (the most important single function of the timeline) and filter contextually rather than linearly (by filtering content through the Tags).

  • Composites are engineered or naturally occurring materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct within the finished structure. Basically, they can be categorized into two major types, i.e., structural composites with outstanding mechanical properties and functional composites with various outstanding physical, chemical or electrochemical properties. They have been widely used in a wide variety of products, e.g.

  • Teaching language as an activity is important especially where learners lack the expected writing proficiency. In Andhra Pradesh, it has been observed that many ESL learners at class IX level, especially those from regional medium schools do not have the required writing proficiency. This could be because of several factors such as inadequate writing practice in the classroom, poor vocabulary, examination oriented writing, teacher- dictated writing, lack of exposure to English, lack of a homogenous English speaking community, limited reading habits and so on.
