  • Owing to the diffusion ofmaterial fromone foil to another, no borderline limitations between single foils in terms of heat transfer exist any more. Thus, the thermal behavior of diffusion-bonded devices is superior in comparison to that of the devices manufactured by other bonding techniques. In Figure 1.13, the diffusion bonding process chain is shown clockwise, starting with the single foils stack of a cross-flow stainless steel device. Figure 1.14 shows a cut through a diffusion-bonded stainless steel device.

  • Among these taxa, bacteria are very important because they play a crucial role in most biogeochemical cycles in marine ecosystems (Fenchel, 1988), taking part in the decomposition of organic matter and the cycling of nutrients. Bacteria are also an important source of food for a variety of marine organisms (Das et al., 2006), and their activity has a major impact on ecosystem metabolism and function.

  • A key reason is that agricultural production has few technical (dis) economies of scale, implying that a range of production forms can coexist. A look at the 300 or so publicly listed companies in table 4 illustrates this point. Even though farming accounts for 22 percent of the global agricultural value chain, it makes up a mere 0.2 percent of equity market capitalization. As of October 2009, there were only seven publicly listed farming companies worldwide, three in Brazil and Argentina and four in Ukraine and Russia.

  • Because larger firms are much more likely to be covered by collective bargaining contracts and works councils, a closely related issue concerns the independent role of firm size in providing wage insurance. As firm size is typically viewed as a good proxy for capital market access (e.g., Gertler and Gilchrist 1994), insurance contracts should be particularly apparent for individuals working at larger employers.

  • The success with organic foods depends on consumer acceptance and use. Potential consumers may not even be aware of organic foods or may have the wrong perception even when aware. More knowledge could lead to increased use of organics due to the link between awareness and purchases. Briz and Ward (2009) argue that while awareness is based on consciousness, consumption requires an explicit buying commitment that should be influenced by price and appropriate measure(s) of the organic quality. These may be important attributes to consider increasing organic food consumption. ...

  • Beginning with Titman and Wessels (1988), then Rajan and Zingales (1995) and more recently Frank and Goyal (2004), the empirical corporate finance literature has converged to a limited set of variables that are reliably related to the leverage of non-financial firms. Leverage is positively correlated with size and collateral, and is negatively correlated with profits, market-to-book ratio and dividends.

  • We use data from the Expenditure and Food Survey (EFS), which is administered every year in the UK. The annual sample includes between six and seven thousand households. For each household, an initial interview collects detailed demographic information. Immediately after the interview, each household member starts a expenditure diary, in which they record everything they buy during the next fourteen days. Diary expenditures are aggregated to “diary weeks” in the data, for reasons of confidentiality, resulting in two seven-day aggregates of expenditure for each individual.

  • Today’s student population is technology driven and there is an ongoing need for learning spaces and furniture to meet these rapidly developing demands. Students no longer rely on printed materials as their primary resource for learning. Instead they make frequent and steady use of digital information in support of their studies and research. IT has fundamentally transformed the educational environment and its integration into the curriculum is redefining the perception of a quality school. The selection and planning of furniture has responded to this evolution.

  • Important player for the regulation of gingival connective tissue homeostasis is the fibroblast, cell able to synthesize and breakdown the collagen fibers and other proteins from the ground substance. In vitro studies have shown that fibroblasts from human normal gingiva produce collagens type I and type III, while cells derived from gingiva of patients with chronic periodontitis failed to produce detectable amounts of type III collagen (Hammouda et al., 1980; Chavier et al., 1984, as cited in Bartold & Narayanan, 2006)....

  • They use geological and distribution data on the island’s 1,284 plant genera and more than 2,000 endemic plant taxa to identify 19 biomes there, and they describe complex conservation challenges. The next chapter by Benny Chan and Pei-Fen Lee explores the biogeography of the barnacles of Taiwan, relating taxon distributions to coastal geomorphology and the complex array of oceanic currents around the island. Global climate changes in ocean water temperature may permit southerly, warmwater taxa to expand northward, invading habitat presently occupied by coldwater taxa....

  • Until recent years, cultivars’ identification was based only on morphological and agronomic traits. However, recognition of olive cultivars based on phenotypic characters revealed to be problematic, especially in early stages of tree development. Traditionally diversity within and between olive tree cultivars was determined by assessing differences in olive tree, namely leaf shape and color, and olive fruits morphology.

  • At the Kabupaten level, the average relative cash flow per worker is 74 million Rp (with 95% confidence limits of 70 to 78 million Rp), but the dispersion is high and the spatial heterogeneity among villages is considerable (Figure 18). In some villages, the added value per worker is less than 1 million Rp/year, while others produce more than 600 million Rp/year/worker. There is no clear explanation for the differences, as they are not obviously linked to either the industrial or spatial concentrations.

  • The international consequences of zero-interest-rate policies are also negative. With interbank markets in the U.S. and Europe congested, forward foreign exchange markets become more difficult to organize. Without forward cover, exporters and importers find it more difficult to secure normal letters of credit. In the financial panic of 2008, foreign trade imploded much more than domestic trade. In addition, the Fed’s zero interest rate strategy inevitably weakens the dollar in the foreign exchanges.
