  • 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.

  • Basic blue 41 is a very stable dye using in wool weaving industry. Fenton reaction is often used to decompose stable substances in wastewater. In this study planed experiments method was used to investigate the effect of three factors, that are pH, H2O2 and Fe2+ concentration on COD reduction. The response surface was determined by program Modde 5.0, the optimal reaction conditions was: Fe2+ concentration is 120 mg/L, H2O2 concentration is 10 mM, pH is 4.

  • The business view focuses on things that impact the profit and loss (P&L) accounting of an organization. This includes sales, profit, expenses, competition, and costs. Everyone should understand their P&L: it’s what pays their salaries or their contracts. When engineering teams are unaware of how their business works, many decisions made by management will appear illogical or stupid. Thus, it’s in the interest of whoever’s responsible for business planning to help others understand their reasoning.
