Larry Temkin has forcefully argued for the possibility that the value comparative “better than” is not transitive and that the betterness relation can be cyclical. Temkin uses so-called spectrum arguments to argue that the belief that “better than” is transitive is incompatible with other beliefs that are more intuitive, so we should conclude that “better than” is not transitive. I will argue that
In this contribution, a model for the thermomechanically coupled behaviour of case hardening steel is introduced with application to 16MnCr5 (1.7131). The model is based on a decomposition of the free energy into a thermo-elastic and a plastic part. Associated viscoplasticity, in terms of a temperature-depenent Perzyna-type power law, in combination with an isotropic von Mises yield function takes
Values, such as liberty and equality, are sometimes said to be incommensurable in the sense that their value cannot be reduced to a common measure. And options, such as studying to become a lawyer or studying to become a philosopher, are sometimes said to be incomparable in the sense that neither option seems to be at least as good as the other. These possibilities are thought to raise deep questi
BACKGROUND: Spending time in natural environments is beneficial for mental health and cognitive function. Unfortunately, many elderly citizens, who would potentially gain from these beneficial effects, have limited or no access to natural environments. Virtual reality may provide the experience of being present in a natural environment without the need of transportation. OBJECTIVE: The purpose of
In this chapter, the authors highlight that the challenges related to managing modern projects are that the management problems have changed since traditional project management methods were developed. This calls for new project management methods, adapted to situations of rapid technological change and flexibility. The authors identify and highlight the limitations of both traditional and agile m
Cryptosystems based on the learning with errors (LWE) problem are assigned a security level that relates to the cost of generic algorithms for solving the LWE problem. This includes at least the so-called primal and dual lattice attacks. In this paper, we present an improvement of the dual lattice attack using an idea that can be traced back to work by Bleichenbacher. We present an improved distin
Objectives: Vitamin D (25(OH)D) deficiency and metabolic syndrome (MetS) may both contribute to increased cardiovascular risk in SLE. We aimed to examine the association of demographic factors, SLE phenotype, therapy and vitamin D levels with MetS and insulin resistance. Methods: The Systemic Lupus International Collaborating Clinics (SLICC) enrolled patients recently diagnosed with SLE (<15 month
The comprehensive prehistoric settlement Uppåkra, lasting over a millennium,raises questions on how food supplies and local communities were agriculturally organized. Recent investigations of archaeobotanical remains from theregional center Uppåkra and several surrounding settlements have contributed to new aspects of their agricultural relations. New patterns in consumption show that through i
Background: Burns are a global public health concern, with the majority of the disease burden affecting low- and middle-income countries. Yet, as suggested by previous publications, there is a widespread belief that literature about burns in low- and middle-income countries is lacking. Therefore, we aimed to assess with a scoping review, the extent of the literature output on burns in East Africa,
“Wet” eldercare facilities for people who age with long-term substance use problems and complex needs exist in several countries. Residents are accepted as active users of alcohol and drugs, and while the media has presented the permissive policies of the facilities in a positive light, others have described these policies as harmful. The aim of this article is to analyze residents' and staff memb
The roughly 600 km long Central Cordillera of Colombia shows a varied tectonic, magmatic, and exhumation history, despite the reasonably homogenous appearance concerning topography, outcropping lithologies, and strike. Here we show with new geo-thermochronological data the thermal evolution of the southern Central Cordillera since the Early Jurassic. Extensive Jurassic magmatism is recorded by U–P
The general outline of the long-term history of cereal cultivation in southern Sweden is relatively well known from published compilations of archaeobotanical data (Hjelmqvist 1955; Engelmark 1992; Gustafsson 1998; Viklund 1998; Grabowski 2011). These compilations show emmer (Triticum dicoccum) and naked barley (Hordeum vulgare var. nudum) as the principal crops of the Neolithic and the Early Bron
Drug use disorders (DUD) are associated with psychiatric illness and increased risks of suicide. We examined health care utilization prior to suicide in adults with DUD, which may reveal opportunities to prevent suicide in this high-risk population. A national cohort study was conducted of all 6,947,191 adults in Sweden, including 166,682 (2.4%) with DUD, who were followed up for suicide during 20
Functional data analysis is typically performed in two steps: first, functionally representing discrete observations, and then applying functional methods, such as the functional principal component analysis, to the so-represented data. While the initial choice of a functional representation may have a significant impact on the second phase of the analysis, this issue has not gained much attention
Magnetic fields can alter the growth of nanomaterials and, in some cases, ultimately lead to room temperature ferromagnetism (RTF). One promising approach for the growth of nanomaterials is thermal oxidation with both academic and industrial relevance. In this study, we evaluate the growth of copper oxide (CuO) nanowires by thermal oxidation method in a furnace adapted with a static magnetic field
Although virus-negative Merkel cell carcinoma (MCC) is characterized by a high frequency of UV-induced mutations, the expression of two viral oncoproteins is regarded as a key mechanism driving Merkel cell polyomavirus‒positive MCC. The cells in which these molecular events initiate MCC oncogenesis have yet not been identified for both MCC subsets. A considerable proportion of virus-negative MCC i
The new cis-dioxomolybdenum (VI) complexes [MoO2(L2)(H2O)] (2) and [MoO2(L3)(H2O)] (3) containing the tridentate hydrazone-based ligands (H2L2 = N'-(3,5-di-tert-butyl-2-hydroxybenzylidene)-4-methylbenzohydrazide and H2L3 = N'-(2-hydroxybenzylidene)-2-(hydroxyimino)propanehydrazide) have been synthesized and characterized via IR, 1H and 13C NMR spectroscopy, mass spectrometry, and single crystal X-
Electrochemical removal of nitrogen oxides (NOx) by solid electrolyte cells (SECs) is a promising technology due to no required reductant. Herein, a series of La0.8Sr0.2Mn1−xNixO3 (0 ≤ x ≤ 0.5) perovskites were first synthesized and utilized as the electrode materials of SECs. The role of Ni substitution in electrode performance and NOx reduction mechanism were revealed by various experimental cha
We have performed extensive investigations of laser-induced fluorescence in animal and human tissue aimed at instant tissue characterization. Autofluorescence, as well as specific fluorescence from HPD/DHE and other photosensitizers, has been utilized. The studies have been focused on the demarcation of malignant tumours and atheroscleortic plaques. A nitrogen laser or an excimer-pumped dye laser
Caused by SARS-CoV-2, COVID-19 has become a severe threaten to society and human health, its epidemic control emerges as long-term issue. A sustainable epidemic and environmental transmission risk control (SEERC) in urban area is urgently needed. This work aims to conduct a new investigation on the transmission risk of SARS-COV-2 as virus/hazardous material through various environmental medias, ro
