Boken är en översiktlig syntes av det egyptiska pyramidbyggandet, från de första mastaborna till pyramidkonstruktionerna i Nubien.

High latitude mires are key ecosystems in the context of climate change since they store large amounts of carbon while constituting an important natural source of methane (CH4). However, while a growing number of studies have investigated methane fluxes (FCH4) at the plot- (~1 m2) and ecosystem-scale (~0.1–0.5 km2) across the boreal biome, variations of FCH4 magnitudes and drivers at the mesoscale

In a potato starch factory, potato proteins can also be obtained alongside the main product starch. After the denatured proteins have been withdrawn, the remaining potato fruit juice (PFJ) can be further concentrated through evaporation and used as a fertilizer. However, evaporators are highly energy-intensive. Instead, membrane filtration presents a more energy-efficient alternative for this proc

On-site hydrogen gas production from hydrogen-rich liquids offers a clean alternative to fossil fuels for combustion that is readily implemented in existing energy infrastructure. A heterogenized (POCOP)-Ir pincer catalyst can be operated at higher temperatures for higher turnover frequency, but the reaction pathway of the reported complex has not been well understood. Here, we report intermediary

Nutrients are the lifeblood of aquatic ecosystems, but not all nutrients are equally accessible to the organisms that depend on them. While traditional monitoring often tracks total or inorganic concentrations of carbon, nitrogen, and phosphorus, these measures do not reflect what microbial communities can actually use. This thesis explores that disconnect by investigating the bioavailability of k

The aim of this chapter is to analyse and describe how teachers’ use of theoretical conjectures in instruction during a Learning Study (LeaS) process affected high-functioning autism spectrum disorder (HFASD) students’ learning outcomes when following the national curriculum. Participants were students in grades 7 to 9 (n = 11) and their teachers (n = 5). The 11 adolescents (4 females and 7 males)

Serving Aristocracy is the history of social negotiation and mobility in an early modern knowledge community, centred on the aristocratic De la Gardie family and their sphere of manors and estates in seventeenth-century Sweden. Focusing on underprivileged women and men and the knowledge community that shaped their interactions, social negotiations, and mobility, this book documents ordinary people

I denna bok återpublicerar jag sex artiklar om den moderna skönlitterära svenska prosan. Två av artiklarna ger fördjupade analyser av Kerstin Ekmans romaninledningar i Urminnes tecken (2000) respektive Skraplotter (2003). En handlar om kvantitativ metod som redskap vid stilanalys. Övriga artiklar behandlar den skönlitterära prosan som språkligt material och tar upp tempusbruk, interpunktion och or

BackgroundCerebral small vessel disease (CSVD) is one of the most important causes of cognitive decline. Only a few previous studies have evaluated lung function measures in relation to brain neuropathological changes, and even less studies on specific lesions and areas that could shed light on mechanisms of CSVD.ObjectiveThe aim was to study the association between lung function and CSVD in the g

AimsAdipose tissue distribution, metabolism, and expansion capacity exhibit notable sex- and depot-specific differences. Herein, we monitored adipocyte traits related to insulin responsiveness and glucose transport during adipose expansion in visceral and subcutaneous fat from male and female mice.Material and methodsAdipocytes were isolated from perigonadal and inguinal adipose tissue of chow-fed

ABSTRACT Intact insulin signaling and glucose transport in adipocytes are crucial to maintaining whole-body energy metabolism. Focal adhesion kinase stands as a central intracellular protein facilitating signaling between the extracellular matrix and the cytoplasm, thereby regulating cellular metabolism. Here, we have investigated the role of focal adhesion kinase in adipocyte glucose transport us

I study the economic returns to migration among Swedish immigrants in the United States in 1900 and 1910, by social class. Using linked data from full-count Swedish and US censuses via the Swedish Emigrant Register, I first estimate the rates of return to migration using two identification strategies, with the returns exceeding 60 percent, notably higher for migrants from lower social classes. Fur

Testning och materialmodellering av gummipackningar i värmeväxlare För att en plattvärmeväxlare ska kunna fungera på ett effektivt sätt är det viktigt att ha packningar som klarar den höga belastningen. Detta examensarbete har inneburit att testa och anpassa nya materialmodeller för ett antal packningsmaterial för att förbättra utvecklingen i framtiden. Examensarbetet är gjort i samarbete med AlThe aim of this master's thesis is to establish material models for three rubber materials using macroscopic data collected using Digital Image Correlation, DIC. DIC is a non-contact optical technique for measuring strain and displacement in a material by tracking points on a material during the deformation process.\\ The rubber materials are tested in both uniaxial tension and compression, fr
