  • In the early 1980’s, the Japanese were the first to recognize dairy components as having significant contributions to “physiologically functional foods.” Since then there has been an increasing number of investigations that have supported this view.Current evidence for the health benefits of most dairy foods and dairy components is based primarily on in vitro and in vivo animal studies. Human clinical studies are still needed in many areas.

  • For half a billion women in developing regions worldwide, anemia is a life-long burden, one which affects most of their infants and young children as well. Controlling anemia in these vulnerable groups could significantly reduce maternal and infant morbidity. It would also enhance intellectual and work capacity, thereby improving family, community and national socioeconomic development. In May 2002, the General Assembly of the United Nations reemphasized that control of nutritional anemia should be one of the global Development Goals to be achieved in the early years of this new millennium.

  • Digital objects have characteristics, or unique features, based on their creator and function. For example, the characteristics of a hard disk sector will be different when it is used to store the contents of an ASCII text document versus a JPEG image. We can use the characteristics to identify the data. The state of an object is the value of its characteristics. If a letter were changed in an ASCII text document, then the object corresponding to the file would have a new state. Similarly, the state of a running computer process changes every time data is written to its memory....

  • We present an LFG-DOP parser which uses fragments from LFG-annotated sentences to parse new sentences. Experiments with the Verbmobil and Homecentre corpora show that (1) Viterbi n best search performs about 100 times faster than Monte Carlo search while both achieve the same accuracy; (2) the DOP hypothesis which states that parse accuracy increases with increasing fragment size is confirmed for LFG-DOP; (3) LFGDOP's relative frequency estimator performs worse than a discounted frequency estimator; and (4) LFG-DOP significantly outperforms TreeDOP if evaluated on tree structures only.

  • Whereas most membrane receptors are oligomeric entities, G-protein-coupled receptors have long been thought to function as monomers. Within the last 15 years, accumulating data have indicated that G-protein-coupled receptors can form dimers or even higher ordered oligomers, but the gen-eral functional significance of this phenomena is not yet clear.

  • Programming a computer to operate to a significant degree as an author is a challenging research task. The creation of fluent multiparagraph text is a complex process because knowledge must be expressed in linguistic forms at several levels of organization, including paragraphs, sentences and words, each of which involves its own kinds of complexity. Accommodating this natural complexity is a difficult design problem. To solve it we must separate the various relevant kinds of knowledge into nearly independent collections, factoring the problem. ...

  • In another recent study by our group (Gürlek et al. 2009) similar salivary ICTP levels were detected in smoker, non-smoker and ex-smoker patient groups with similar clinical periodontal findings. Smoking status was confirmed by salivary cotinine analysis but there was no clinically healthy control group in that study and the number of teeth present, average probing depths and attachment levels were all similar in the three study groups. There were no significant differences in saliva ICTP concentrations between the smoker and non-smoker patient groups.

  • For much of history, few things have mattered more to humans than their relations with soil. This is evidenced by a rich historical literature on aspects of soil management and soil fertility, dating back to texts of ancient civilizations of the Middle East, the Mediterranean, China, and India (see McNeill and Winiwarter 2004).

  • The three stages shown in Figure 1 are intended to demarcate three macro-stages of writing development. Writing skill is shown as continuously improving as a function of practice, as is typical for perceptual-motor and cognitive skills in general. The micro- changes underlying the gradual improvement that drive the transition to the next macro-stage fall beyond the scope of the present article.

  • In recent years, great focus has been placed upon polymer thin films. These polymer thin films are important in many technological applications, ranging from coatings and adhesives to organic electronic devices, including sensors and detectors. Polymers can be prepared using chemical and/or electrochemical methods of polymerization. There are a few advantages of electrosynthesis over chemical methods.

  • Does this mean that differences in genetic diversity levels will have predictable ecological consequences? The answer is no, because only one portion of genetic diversity is connected to ecological factors, i.e. adaptation. Ecological adaptation is a significant factor for example, in range expansion of plant species. Plants with different genotypes conferring the highest levels of fitness are expected to survive and reproduce better, shifting the gene pool over time towards higher frequencies of the alleles making up the more successful genotypes (Ward et al., 2008).

  • Bacteria are non-chlorophyllated unicellular organisms that reproduce by fission and do not present nuclear envelope. Gram´s stain is a staining technique used to classify bacteria based on the different characteristic of their cell walls. Gram-positive or Gram-negative bacteria are determined by the amount and location of peptidoglycan in the cell wall, exhibiting different chemical compositions and structures, cell-wall permeabilities, physiologies, metabolisms, and pathogenicities.

  • Writing an extended text at an advanced level involves not just the language system. It poses significant challenges to our cognitive systems for memory and thinking as well. Indeed, writers can put to use virtually everything they have learned and stored away in long-term memory. But they can only do so if their knowledge is accessible, either by rapidly retrieving it from long-term memory or by actively maintaining it in short-term working memory. Thinking is so closely linked to writing, at least in mature adults, that the two are practically twins.
