BACKGROUND: Current diagnostic criteria for postural orthostatic tachycardia syndrome (POTS) require history of orthostatic intolerance and heart rate elevation of ≥30 bpm in adults or ≥40 bpm in adolescents during a 10-minute standing or a tilt table test. Many patients with orthostatic intolerance experience autonomic dysfunction and functional impairment despite not meeting the required heart r
Despite the prevalence of slavery in world history, our understanding of its persistence remains limited. Most previous studies focus primarily on slavery as a labour contract, indistinguishable from other coercive arrangements such as serfdom. More recent literature on slavery in the United States shows that enslaved people also played an important role as financial instruments. In this article,
The economic history of British colonialism in Southern Africa is defined by three interrelated dynamics: the initial expansion driven by chartered companies, a substantial influx of European settlers, and the establishment of racially segregated, unequal Neo-European societies. In this chapter, we show how the discovery of minerals in the nineteenth century radically reshaped the economic and soc
Understanding the determinants that influence parents’ decisions to participate with their infants in primary prevention trials is essential for achieving representative study samples and ensuring the generalizability of outcomes. We analyzed quantitative and qualitative data collected from infants eligible for the Primary Oral Insulin Trial (N= 2,750) or the Supplementation with B. INfantis for M
The Sloan Digital Sky Survey-V (SDSS-V) Magellanic Genesis Survey is a spectroscopic program designed to map the kinematic and chemical structure of the Magellanic Clouds (MCs) using APOGEE and BOSS spectroscopy. This overview describes the survey’s design, target selection, and science goals and highlights some first results using these data. In the inner regions of the Large and Small Magellanic
Protest and activism are endemic and potent features of many nations’ political life and critical potential counters to democratic backsliding and authoritarianism. In this review article, we meta-analytically examine six decades of research findings on what explains participation, focusing particularly on two well-studied protest forms: marches and demonstrations. Focusing on these iconic and com
Surface-enhanced Raman scattering (SERS) has emerged as a powerful technique for the rapid and sensitive detection of pesticide residues, particularly targeted pesticides of concern in food safety. However, hotspot intensification strategies in hydrogel-based SERS substrates that rely on solvent-exchange-induced shrinkage often suffer from concomitant analyte loss, thereby limiting detection relia
Wild edible fruits are underexplored sources of nutrients and bioactives. This study assessed the bioactive profileand in vitro functional properties of four Mozambican wild fruits: Adansonia digitata (AD), Dialium schlechteri (DS),Garcinia livingstonei (GL), and Syzygium cordatum (SC). Phenolic compounds (PCs), dietary fibers (DF), minerals,and sugars were analyzed along with phenolic bioaccessibWild edible fruits are underexplored sources of nutrients and bioactives.

This thesis comprises three papers in the field of proof complexity, in which the objects of study are certificates of unsatisfiability. In algebraic proof complexity, the aim is to prove lower bounds on the complexity of certifying that there is no common root of a given set of polynomials. We will be especially concerned with the polynomial calculus proof system, where this is accomplished by it
The starting point of this dissertation is the increasing number of Swedish consumers who use the Internet for shopping. Convenience is said to be an important ground for this choice. However, there are few studies that attempt to understand the true meaning of convenience. This study sets out to understand what convenience entails for Internet shoppers, what characterizes a convenient Internet sh
In order to provide a functional foodscape in the grocery store, chilled products need to be stored in cabinets according to the regulations. Doors on display cabinets are energy-efficient but can also be perceived as a barrier by consumers. The purpose of this paper is to contribute to an understanding of how consumers behave and what they perceive when shopping chilled groceries from cabinets wi
This chapter contributes to the understanding of the impulsive fashion consumer online in a digitalized retail and consumer world. It also questions the notions of impulsive consumption in general. The description of the impulsive fashion consumer as guided by emotional irrationality is questioned and disputed, as the digitalization transforms the retailing concept, alters consumer's way of thinki
