The occurrence of within-population variation in germination behavior and associated traits such as seed size has long fascinated evolutionary ecologists. In annuals, unpredictable environments are known to select for bet-hedging strategies causing variation in dormancy duration and germination strategies. Variation in germination timing and associated traits is also commonly observed in perennial

Lignin constitutes an impressive resource of high-value low molecular weight compounds. However, robust methods for isolation of the extractable fraction from lignocellulose are yet to be established. In this study, supercritical fluid extraction (SFE) and CO2-expanded liquid extraction (CXLE) were employed to extract lignin from softwood and hardwood chips. Ethanol, acetone, and ethyl lactate wer

This short article introduces a novel framework for conceiving of the substantive representation of marginalized groups – in this case, racially minoritized women in the UK House of Commons. I outline a rubric of eight facets of substantive representation. These evaluate the degree to which claims that constitute a group are also substantively representative of that group. In doing so, I contribut

Critical StagesUnstable Grounds: Reconfigurations of Performance and PoliticsSpecial Issue, June 2021Gigi Argyropoulou and Stefanie SachsenmaierThis issue explores operations of performance during unstable conditions marked by socio-political, environmental, economic and further challenges. It is particularly interested in histories, reconfigurations and mutations of performance practice as it see

Nationalism has trumped solidarity, resulting in unnecessary loss of life and inequitable access to vaccines and therapeutics. Existing intellectual property (IP) regimens, trade secrets and data rights, under which pharmaceutical firms operate, have also posed obstacles to increasing manufacturing capacity, and ensuring adequate supply, affordable pricing, and equitable access to COVID-19 vaccine

Using a data set of 1.1 million speeches drawn from UK House of Commons debates during 1997–2017 and a combination of automated and manual content analysis, this study addresses three interrelated questions. First, to what extent are minoritised women constitutively represented in parliamentary debates? Second, which MPs do so? Third, how do MPs’ race and gender affect how they represent minoritis

The Bi-based superconductors of approximate compositions Bi2Sr2CuO6 and Bi2Sr2CaCu2O8, and the closely related Aurivillius phases, Bi2BaNb2O9 and Bi4Ti3O12, are discussed from a group theoretical point of view. The structural complexities associated with these phases are treated in terms of successive modulation of an appropriately chosen parent structure. The space-group symmetries of the two Aur

Aluminium doped Si layers grown either by solid phase epitaxy (SPE) or molecular beam epitaxy (MBE) have been investigated over wide ranges of Al fluxes (J(Al) = 1 x 10(10)-3 x 10(13) cm-2s-1) and growth temperatures (T(s) = 500-900-degrees-C), using RHEED, LEED and AES during growth and cross section TEM of the as-deposited layers. For MBE growth, defect free films could be grown almost in the wh

Dual target magnetron sputtering has been used to grow single-crysal MoV superlattice structures (SLS) with modulation wavelengths λ ranging from 0.6 to 17.7 nm on (001) oriented MgO substrates held at temperatures Ts between 600 and 900°C. High resolution cross-sectional transmission electron microscopy (HRXTEM) images and comparisions between experimental and calculated X-ray diffraction (XRD)

In many civil engineering problems, soil is stabilized by a combination of binders and water. The success of stabilization is evaluated using seismic tests with measured P-wave velocities. Optimization of process, laboratory testing and data modelling are essential to reduce the costs of the industrial projects. This paper reports the optimized workflow of soil stabilization through evaluated effe

About the book:"The Routledge Companion to Theatre and Politics is a volume of critical essays, provocations, and interventions on the most important questions faced by today's writers, critics, audiences, theatre and performance makers. Featuring texts written by scholars and artists who are diversely situated (geographically, culturally, politically, and institutionally), its multiple perspectiv

Background Among individuals with alcohol use disorder (AUD) and drug use disorder (DUD), is their genetic liability and its specificity moderated by substance availability? Methods Offspring (born 1960-1995) and their biological parents from three family types [not-lived-with (NLW) biological father, mother and adoptive] and their AUD and DUD diagnoses were ascertained from Swedish national regis

This paper argues that cost-effectiveness analysis in the healthcare sector introduces a discrimination risk that has thus far been underappreciated and outlines some approaches one can take toward this. It is argued that appropriate standards used in cost-effectiveness analysis in the healthcare sector fail to always fully determine an optimal option, which entails that cost-effectiveness analysi

The European Congenital Heart Surgeons Association (ECHSA) Congenital Database (CD) is the second largest clinical pediatric and congenital cardiac surgical database in the world and the largest in Europe, where various smaller national or regional databases exist. Despite the dramatic increase in interventional cardiology procedures over recent years, only scattered national or regional databases

Bygg- och anläggningsbranschen har störst påverkan på klimatet som bransch. Sverige har som mål att nå noll nettoutsläpp av växthusgaser innan 2045 och masshanteringen är en stor bidragande faktor till den stora klimatpåverkan. Stora mängder massor hanteras och transporteras, där en liten procent återanvänds. Det föreslås därför i branschen att cirkuläritet ska införas för att skapa en mer hållbarThe infrastructure industry, the soil management in particular, has a significant impact on the climate. The great mass movement that occurs in an infrastructure project needs management and transport and in addition there is only a small percentage that is reused. A more circular approach has been suggested to be applied in the industry. A case study was performed of three infrastructure projects
