  • The optimum conditions obtained from response surface analysis was 4.99 g/100 g moisture, 1.05 mm particle size and 9.2 h extraction time. Under these optimum conditions, the maximum fat yield was 37.35 g/100 g. The extracted fat was a white solid at room temperature. The physical and chemical characteristics of the extracted fat compared well with those of conventional fats,...Invite you to consult the documentation.

  • With the advent of the atomic force microscope (AFM) came an extremely valuable analytical resource and technique, useful for the qualitative and quantitative surface analysis with sub-nanometer resolution. In addition, samples studied with an AFM do not require any special pretreatments that may alter or damage the sample, and permit a three dimensional investigation of the surface.

  • The same amount of water has been present on our planet for about 4 billion years, since shortly after the Earth was formed. Since then it has cycled through evaporation, condensation, precipitation and surface runoff multiple times. Water scarcity as an abiotic factor ranging from moderate to severe stress levels, accompanied by loss of moisture in the soil, is extremely hard for most organisms to cope with, particularly terrestrial plants and their food-chain dependents.

  • Moreover, one's labour market status may be expected to have a (reverse) causal effect on current and future health. In this paper we analyse the relative importance of these endogeneity and measurement issues in the context of a model of early retirement decisions. We state assumptions under which we can use relatively simple methods to assess the relative importance of state dependent reporting errors in individual responses to health questions. The estimation results indicate that among respondents...

  • My examples satisfy some aspects of this requirement, but not others. In each of the examples, there clearly are relations, however simple, between doing and undergoing. I undergo an experience, such as feeling that my hands are cold, and take action in response, warming my hands by caressing the sides of my mug. I adjust what I am doing in response to sensations that indicate the mug is too hot to grasp for any extended period; and I put the mug down once my sensations suggest that my hands have been sufficiently warmed. This...

  • South-east Asian components of our population are increasing rapidly. The ethnic mix in each organisation is likely to be quite different, so the best approach may be to develop anthropometric distributions for each organisation from different data sets, using the proportions of each ethnic group. Some applications of anthropometric data are discussed below. The arrangement of equipment on a working surface should be based on placing the most frequently used items within the easiest reach.

  • The basic physics of sound propagation are simple, but the interaction of sound pressure waves with complex shapes and multi-layer constructions with openings, as you find in buildings, is more challenging. Controlling noise, both from the internal and external environment and from the internal mechanical and electrical services in buildings, is essential to create environments that promote aural communication and comfortable working conditions.
