  • The terms “cosmetic tattooing” or “permanent makeup” (e.g. micropigmentation) refer to mechanical application of pigmented materials to the area of the eye, lips and face for the purpose of changing the color or appearance of that facial feature. This is a rapidly growing business in the United States becoming mainstream in many sociological circles.

  • To elucidate the chemical interactions underlying the role of metallothioneins (MTs) in reducing the cytotoxicity caused by MeHg(II), we monitored in parallel by electronic absorption and CDspectroscopies the stepwise addition of MeHgCl stock solution to mammalian Zn7-MT1 and the isolated Zn4 -aMT1 and Zn3 -bMT1 fragments. The incor-poration of MeHg + into Zn7-MT and Zn3-bMT entails total displacement of Zn(II) and unfolding of the protein. However, both features are only partial for Zn4 -aMT.

  • With a shared server architecture, a small pool of server processes can serve a large number of clients. This reduces the server’s memory requirements. Connection pooling and session multiplexing features are enabled through shared server. Connection Pooling Connection pooling enables the database server to time out protocol connections and to use those connections to service an active session. Session Multiplexing Session multiplexing, available with Oracle Connection Manager, enables multiple client sessions to funnel through a single protocol connection. ...

  • In the recharge area, oxidising conditions occur and dissolution of calcium and bicarbonate dominates. As the water continues to move down dip, further modifications are at first limited. By observing the redox potential (Eh) of abstracted groundwater, a sharp redox barrier was detected beyond the edge of the confining layer, corresponding to the complete exhaustion of dissolved oxygen. Bicarbonate increases and the pH rises until buffering occurs at about 8.3.

  • The EU Water Framework Directive (2000/60/EC) is probably the most significant legislative instrument in the water field that was introduced on an international basis for many years. It moves towards integrated environmental management with key objectives to prevent any further deterioration of water bodies, and protect and enhance the status of aquatic ecosystems and associated wetlands. It aims to promote sustainable water consumption and will contribute to mitigating the effects of floods and droughts.

  • In the last two decades, the discovery of signaling roles of ROS demonstrated their universal use in biological systems. The third section of this book, entitled “Reactive Species as Signaling Molecules” contains the chapters covering clear ROS-based signaling in yeasts and plants. It is not strange that many authors provide readers with the information gained from yeasts. This is a very popular classic eukaryotic model system to disclose molecular mechanisms of cellular responses to oxidative stress (Lushchak, 2010). In the first chapter of this book section, M. A.

  • Jonathan Demme’s film is one of the most important films of the 1990s winning Oscars for best film, director, actor, actress and adapted screenplay. This was groundbreaking because a film with such lurid subject matter (it is the tale of two serial killers) had never achieved this status before. The film could be described as a hybrid genre film mixing the police procedural/detective thriller genre with the horror movie.

  • The following sections provide an overview of the technical and qualitative characteristics of a wide range of alternative fuels that can replace coal in cement kilns. These fuels include agricultural and non-agricultural biomass, chemical and hazardous wastes, petroleum-based wastes, and miscellaneous waste fuels. Each of these alternatives are described in detail, including a discussion of average substitution rates, energy and water content of the fuels, carbon dioxide emissions factors, and change in carbon emissions per ton1 of coal replacement.

  • Balanced and coordinated advances within these research areas will pave the way to meeting the 2020 vision target of a fivefold increase in renewable resource use. Figures 11A to 11D detail goals for these priority research areas. Cost of materials surfaced many times as a major issue during the steering group’s investigations. Lowering unit costs is critical for sustainable economic growth.

  • In this study, structural features of Tricholoma matsutake polysaccharide (TMP-A) were investigated by a combination of infrared (IR) spectra, gas chromatography–mass spectrometry (GC–MS), nuclear magnetic resonance (NMR) spectroscopy. The results indicated that TMP-A had a backbone of 1,4-- d-glucopyranose residue which branches at O-6 based on the experimental results. The branches were mainly composed of an (1→3)--d-galactopyranose residue, and terminated with -d-xylopyranose residue.

  • Social determinants of health have a strong influence on a wide diversity of health endpoints. The same is valid for the field of environmental health, as the exposure to environmental risk factors is also unequally distributed, and this unequal distribution is often related to social characteristics such as income, social status, employment and education, but also non-economic aspects such as gender, age or ethnicity. However, depending on the environmental risk and the “risk group” considered, the magnitude of inequality varies largely.

  • Romans held Greek civilization in high regard and, like us, considered fifth-century-BC Greece to be the region’s golden age, a time characterized by refined artistic and cultural production, scholarship, and military strength. During his reign five hundred years later, Augustus sought to align his rule with this era and promote a rebirth of the golden age of Greece in Rome. Augustus’s interest in Greek art and culture strengthened Roman reverence for classical Greek art, philosophy, and intellectual life.

  • The diversity of coverage experiences seems to indicate that there is no type of service that is per se more or better “insurable” by public or private coverage. There are nonetheless some trends towards greater reliance on public or subsidised private coverage for individuals facing higher health care cost, such as the elderly and those with chronic conditions, even where PHI plays a significant or primary role.

  • Most research on physical activity and colon cancer has focused on occupational physical activity in men. Clearly, men with sedentary jobs have increased risk of colon cancer (Sternfeld, 1992). One of the most comprehensive studies that included women was a case- control study of Utah residents that took into account differences in dietary patterns and body weight, confounding factors not usually controlled (Slattery et al., 1988).

  • We used t-tests with robust standard errors (to account for clustering caused by multiple nutrient comparisons within studies) to test the null hypothesis of no evidence of a difference between organically and conventionally produced food in content of nutrients and other substances. P-values were calculated to determine the significance of observed differences; p-values of less than 0.05 were used as a basis for evidence of significant differences between organically and conventionally produced foodstuffs.

  • There are, actually, no formal Swedish regulations for organic contaminants in sludge. There is an informal agreement between the Swedish EPA, the Farmers Union and the Water and Wastewater Association which includes the recommendations in table 3.1-1. These agreements are based more on practical experience than on scientific data. Sweden also used to have a recommended limit value for toluene, but this has been omitted (WALLGREN 2001).

  • In addition, Kaiser CDSMP participants had 0.2 fewer visits to the emergency room and 0.97 fewer hospital days compared to the year prior to completing the CDSMP. As a result, they reduced their health care costs. For example, if the average cost per day of hospitalization were $1,000 and the average cost of an emergency room visit were $100, the potential savings would be $990 per participant for the first year following completion of the program (0.97 days of hospitalization multiplied by $1,000 plus 0.2 emergency visits multiplied by $100).
