Molten-salt-based nanofluids and ionic-liquid-based nanofluids are developed for thermal storage and heat transfer at relatively high temperatures, in the past few years. Preparation and stabilization techniques are briefly introduced firstly, and then, thermal properties, e.g., specific heat, thermal conductivity and viscosity, are summarized and discussed in detail. The properties are not only a
A reduction in the number of postoperative bed days for patients who underwent appendectomy led to a study of changes in hospital costs of appendectomies for the years 1955, and 1965, and 1975. No significant changes were found in the total hospital costs. However, the postoperative costs decreased by 36 percent from 1955 to 1975 due to a decrease in the mean duration of hospital stay. During the
To remain competitive in the field of manufacturing today, companies must constantly improve the automation loops within their production plants. This can be done by augmenting the automation applications with "smart services" such as supervisory-control applications or machine-learning inference algorithms. The downside is that these smart services are often hosted in a cloud infrastructure and t
There is currently a lack of representative, systematic and harmonised greenhouse gas (GHG) observations covering the variety of natural and human-altered biomes that occur in Africa. This impedes the long-term assessment of the drivers of climate change, in addition to their impacts and feedback loops at the continental scale, but also limits our understanding of the contribution of the African c
Although organizations increasingly acknowledge the communicative importance of employees, and increasingly frame communication as an employee responsibility, communication responsibility remains an unexplored topic in strategic communication research. To address this gap, this study introduces the concept employee communication responsibility and offers insight into factors influencing employees’
R&D related foreign direct investments represent a powerful mechanism for cross-border knowledge sharing that can stimulate the process of technological catch-up. However, low-income countries and smaller middle-income countries remain largely excluded from this kind of global flows of knowledge. In this chapter, we discuss the motivations and implications of this type of FDI for low and middl
Rice, as one of the most important crops in the world, is facing an ever-accelerating challenge from climate change. Epigenetic modification with its substantially high epimutation rate and the possibility for some epigenetic variation to act as a heritable contributor to crop environmental adaptability may hold great potentials for rapid crop breeding. Epigenetic modification is controlled by epi
The orbit and physical parameters of the previously unsolved double-lined eclipsing binary Tyc 5227-1023-1, discovered during the search for RR Lyr variable candidate members of the Aquarius stream, are derived using high-resolution chelle spectroscopy and V, i' photometry. A synthetic spectral analysis of both components has been performed, yielding metallicity [M/H] =-0.63± 0.11 for both stars a
The asymmetric formal hydroamination of enamines using a CuH catalyst is reported. The method provides a straightforward and efficient approach to the synthesis of chiral 1,2-dialkyl amines in good yields with high levels of enantioselectivities for a broad range of substrates, and should have significant value for the preparation of molecules bearing a 1,2-diamine motif.
The value of a statistical life (VSL) is a widely used measure for the value of mortality risk reduction. As VSL should reflect preferences and attitudes to risk, there are reasons to believe that it varies depending on the type of risk involved. It has been argued that cancer should be considered a "dread disease," which supports the use of a "cancer premium." The objective of this study is to in
#104_loga, a nonlinear scale of time, for tpt, tbn. “loga, a nonlinear scale of time” refers to the illusion of nonlinear time perception. This idea suggests that our estimation of time intervals whether on a small (milliseconds) or large (decades) scale should be logarithmic, giving us a subjective experience very different from clock or calendar. Of course, our perception of time is influenced b
