In the above paper, Nembhard and Osothsilp (2001) empirically compared several forgetting models against empirical data on production breaks. Among the models compared was the learn–forget curve model (LFCM) developed by Jaber and Bonney(1996). In previous research, several studies have shown that the LFCM is advantageous to some of the models being investigated, however, Nembhard and Osothsilp (2
It has been known for nearly 30 years that the theoretical and experimental values for the energy of the 2s3s S-1 level in singly ionized boron, B it, differ strongly. Since there is much better agreement for other B II levels, it has been concluded that the experimental value for 2s3s S-1 must be revised. Despite a number of recordings over the years of sliding-spark, hollow cathode and beam-foil
The development of cartilage pathology in osteoarthritis involves excessive damage to the collagen fibrillar network, which appears to be mediated primarily by the chondrocyte-generated cytokines interleukin-1 and tumour necrosis factor alpha and the collagenases matrix metalloproteinase-1 (MMP-1) and MMP-13. The damage to matrix caused by these and other MMPs can result in the production of suffi
Malaria parasites are a major cause of human mortality in tropical countries and a potential threat for wildlife, as witnessed by the malaria-induced extinction of naive Hawaiian avifauna. Identifying resistance mechanisms is therefore crucial both for human health and wildlife conservation. Patterns of malaria resistance are known to be highly polygenic in both humans and mice, with marked contri
We present results of ideal epitaxial nucleation and growth of III-V semiconductor nanowires on silicon substrates. This addresses the long-time challenge of integrating high performance III-V semiconductors with mainstream Si technology. Efficient room-temperature generation of light on silicon is demonstrated by the incorporation of double heterostructure segments in such nanowires. We expect th
The purposes of this thesis are to provide a credible picture of the institutional transformation that I allege is taking place in the field of management education in Poland and to widen the field of application of institutional theory by applying it to the field of management education in Poland. In the study I conceptualise management education as an organisation field. The theoretical framewor
Popular Abstract in Swedish Internationellt satsas det inom bioteknologin för närvarande miljardbelopp på utveckling av mikrosystem för avancerad genom- och proteomikforskning. Genomet avser den uppsättning arvsanlag som varje individ har i varje enskild cell och proteomet är den mängd proteiner som finns i varje organism (cell). Den mängd information som döljer sig i genomet och proteomet förThe aim of this thesis project has been to create miniaturized analytical tools that improve sample preparation for the very rapidly growing field of proteomics research. The presented miniaturized analytical tools provide novel and generic analytical solutions, which are highly adaptable for analysis of various low abundant biomolecules. The adaptability and generality of the analytical technolog
The formation of cyclohexene in the hydrogenation of benzene on a ruthenium catalyst has been studied in a slurry reactor. The reaction was performed in an alkaline aqueous phase in a stirred autoclave of stainless steel. The influence of reaction parameters, e.g. hydrogen pressure, alkali concentration, amount of catalyst and temperature was determined. The influence of poisoning of the catalyst
The type material of Physcia magara Kremp., which is the type species of Seirophora Poelt (Teloschistaceae), is shown to be heterogeneous. It is a mixture of Teloschistes villosus (Ach.) Norman and Ramalina maciformis (Delile) Bory. Physcia magara Kremp. is typified on the T. villosus-part. Teloschistes species with multiseriate hairs, spores with short septa, thick and strongly conglutinated cort
The superoxide anion radical is known to be the first product of photosynthetic reduction of oxygen mediated by a variety of electron carriers. The effectiveness of many of these electron carriers as herbicides, and the toxicity of the superoxide they produce, have been suggested to rule out oxygen reduction as a physiological component of normal photosynthesis. Here results with isolated spinach
Kerr rotation and superconducting quantum interference device magnetometry measurements were performed on ultrathin (Ga0.95Mn0.05)As layers. The thinner layers (below 250 A) exhibit magnetic properties different than those of thicker ones, associated with different microstructure, and some degree of inhomogeneity. The temperature dependence of the field-cooled magnetization of the layers is record
Let ζ(t), η(t) be continuously differentiable Gaussian processes with mean zero, unit variance, and common covariance function r(t), and such that ζ(t) and η(t) are independent for all t, and consider the movements of a particle with time-varying coordinates (ζ(t), η(t)). The time and location of the exists of the particle across a circle with radius u defines a point process in R3 with its points
We demonstrate storage of electrons in semiconductor nanowires epitaxially grown from Au nanoparticles. The nanowires contain multiple tunnel junctions (MTJs) of InP barriers and InAs quantum dots designed such that the metal seed particles act as storage nodes. By positioning a second nanowire close to the seed particle it is possible to detect tunneling of individual electrons through the MTJ at
Objective The aim of this study was to quantify the global burden of osteoporotic fracture worldwide. Methods The incidence of hip fractures was identified by systematic review and the incidence of osteoporotic fractures was imputed from the incidence of hip fractures in different regions of the world. Excess mortality and disability weights used age- and sex-specific data from Sweden to calculate
