Weak subdivision or fragmentation ability of deformed {100} (<100> // ND, normal direction) grains by traditional unidirectional (symmetric) rolling results in uneven deformation during tantalum (Ta) processing. Thus, a recently developed asymmetric cross rolling (ACR) is adopted in this work to enhance the subdivision of {100} grain in Ta sheets. Electron backscatter diffraction (EBSD), transmiss
Fine needle aspiration cytology (FNAC) is a widely accepted safe, simple and rapid diagnostic procedure used in the examination of neoplastic and non-neoplastic lesions of various locations. Since its introduction, FNAC has developed into an effective diagnostic tool practiced in a large majority of medical centres evaluating and treating oncological patients. The role of FNAC has been limited in
In high-income countries, parental age at first birth has increased and this postponement increases the risk of involuntary childlessness or having fewer children than desired. This interview study was conducted in Denmark and Sweden among childless men (n = 29) in their last year of an education. The aim was to explore the role of individual and societal factors on fertility decision-making and m
A simple method of widespread applicability in determining double bond positions in C12, C14, and C16 straight-chain monounsaturated acetates is presented. The analysis is made with a capillary gas chromatograph coupled to a low-resolution mass spectrometer which is operated in the electron impact mode. No chemical derlvatlzation of the unknowns is needed. Five pairs of selected mass spectral frag
Lithium-rich stars in globular clusters are rare. Only 14 have been found so far, in different evolutionary phases from dwarfs to giants. Different mechanisms have been proposed to explain this enhancement, but it is still an open problem. Using spectra collected within the Gaia-ESO Survey, obtained with the GIRAFFE spectrograph at the ESO Very Large Telescope, we present the discovery of the firs
Based on measurements of mould in 17 attics in the north of Sweden, 3 were chosen as a tentative validation of the MRD-model (Mould Resistance Design) for long periods of time (1961-2012). Comparing the measurements and the results from the simulations showed great differences regarding the mould growth depending on the simplifications used in the model. How the leakage was simulated and where the
Calcareous nannofossils are considered to be the most productive calcifying organisms, but the impact of their emergence on the chemistry of the ocean in the Late Triassic is not understood yet. Evolutionary details of this bio-event are missing due to the scarcity of well-preserved outcrops worldwide. The current study focuses on the calcareous nannofossil assemblage of the middle Norian to lower
Bringing together a group of outstanding judges, scholars and experts with first-hand experience in the field of transitional justice in Latin America and Spain, this book offers an insider’s perspective on the enhanced role of courts in prosecuting serious human rights violations and grave crimes, such as genocide and war crimes, committed in the context of a prior repressive regime or current co
Governments across anti-communist Asia, with US backing or tacit consent, devised institutions and practices for marginalising popular forces. Such internalisation of the Cold War involved measures ranging from violence and ideological mobilisation to disciplinary modes of control. With democratisation, Cold War devices for domestic control could remain entrenched or be rolled back. Examining the
BACKGROUND: Non-gonococcal urethritis (NGU) is a common syndrome in men. NGU may have several causes, but many cases are caused by sexually transmitted infections that may also cause complications in their female partners. Chlamydia trachomatis and Mycoplasma genitalium are the most common causes of NGU, but in up to 35% of the cases, none of the known viral or bacterial causes are found. Traditio
Conflict in organizations takes many forms. However, most existing literature on organizational conflict focuses on overt forms of conflict expression and handling. While covert conflict exists and shapes the collective organizing of conflict in organizations, the relationship between overt and covert forms of conflict has not yet been well explicated. This article offers a novel perspective on th
High diagnostic efficiency as well as the optimization of patient and staff doses in positron emission tomography (PET) can be achieved by implementing quality assurance program. This study was focused on the requirements and basic aspects of quality assurance (QA) in PET combined with computed tomography (CT), that include equipment quality control (QC). QA systems include methods of image QC, ex
Plasticity can put evolution on repeat if development causes species to generate similar morphologies in similar environments. Anolis lizards offer the opportunity to put this role of developmental plasticity to the test. Following colonization of the four Greater Antillean islands, Anolis lizards independently and repeatedly evolved six ecomorphs adapted to manoeuvring different microhabitats. By
The prevalence of Artificial Intelligence (AI) in the business landscape is indisputable. However, there are considerable gaps between the visionary ideas businesses communicate and their operational use of AI. The goal of this market survey is to identify companies currently working with AI in the Øresund Region - referred to as AI companies. The survey, conducted between June and September 2020,
Opinion mining on social media posts has become more and more popular. Users often express their opinion on a topic not only with words but they also use image symbols such as emoticons and emoji. In this paper, we investigate the effect of emoji-based features in opinion classification of Uzbek texts, and more specifically movie review comments from YouTube. Several classification algorithms are
Interesting optical properties are obtained if highly ordered interfaces and thin films of large organic molecules are prepared on an atomically flat and clean substrate. Then the optical spectra are very different from those of conventional films and reveal a variety of finestructures. On the basis of one example, quaterthiophene on Ag(111), it is demonstrated that long-range ordered monolayers w
In many bird species, floaters are present on the breeding grounds in one or more years before they breed. There is increasing evidence that they have specific home ranges in which they search for information about current and future breeding opportunities. We investigated the role of prospecting in a migratory European starling (Sturnus vulgaris) population. Radio-tracking showed that male starli
