Nigella damascena seeds were extracted by cold press, in a Soxhlet apparatus and with CO2 The yield obtained with liquid CO2 was only 10.57%. EtOH (1%) increased the yield by 50%. CO2-extracts were separated into the 2 fractions. The yield in the first fraction increased 2 times by increasing the pressure from 150 to 350 bar. EtOH (1%) increased the yield 2 times at 150 bar. Linoleic acid was the

Problem: Vilka är de drivande faktorerna till köbildning på klinikens avdelningar samt hur kan ökad kunskap om dessa faktorer på sikt skapa möjligheter för en effektivare kapacitetsplanering och en förbättrad servicenivå mot klinikens kunder?

Preeclampsia (PE), is a pregnancy related condition afflicting 3-8% of all pregnancies and a main cause of maternal and infant morbidity and mortality. It is thought to originate from a malfunctioning placental that eventually leads to damage to the maternal endothelium, which in turn gives rise to hypertension and organ dysfunction. Oxidative stress holds a central role in the development, progre

ConclusionsPaper I: Complications in Extracorporeal Shock Wave Lithotripsy (ESWL): A cohort study, conclusion: We conclude that there are few complications to modern ESWL treatment. 1 Hz should be used to reduce complications (p=0.025). As there is no indication that 1Hz is less effective than 1.5 Hz, this strongly implies that 1 Hz should normally be the frequency used.Success rate with ESWL alon

ElectricityDo not connect too many multiway sockets to a single electrical socket. Make sure that all multiway sockets are securely fastened. Never leave contacts or multiway sockets on the floor. Additionally, avoid placing them inside, in front of, or under a fume hood, as this poses a fire risk.Do not wind too many cables on the same coil. Overloading the cable can lead to overheating and incre

SummaryLight is indisputably at the origin of life on earth, driving all photo-chemical reactions in atmosphere, biological systems, and “man-made" energy related materials. On the atomic scale level, we can describe these photo-chemical reactions, through a multitude of elementary processes occurring on the ultrafast time scale (from sub femtosecond to picosecond) where the initial energy/light h

Popular Abstract in Swedish När vi drabbas av infektioner är det immunförsvaret som ser till att de invaderande organismerna oskadliggörs. För att immunförvaret skall veta vilka organismer och celler som skall attackeras måste det kunna skilja på kroppseget och främmande. En del främmande organismer lever antingen i symbios med den egna kroppen eller så utgör de inget hot. Teoretiskt sett är mat kThe immune response is designed to protect the body from harmful microbial invasions. However, when the immune system attacks itself instead, an autoimmune reaction starts that damage our own cells, tissues and organs. Despite decades of research concerning the etiology of autoimmune diseases the molecular mechanisms of these disorders are poorly understood as they are complex and influenced by bo

How do we reach zero climate impact? Stefan Nyström, the Administrative Director of the All Party Committee on Environmental Objectives (Miljömålsberedningen*) and researchers from Lund University will discuss how to turn words into action in the Swedish climate policy on the road towards zero emissions.

Agenda 2030 Graduate School monthly newsletter #6 2025-06-09 Ylva van Meeningen Hi! I do not know about you, but I am SO ready for summer and to not check my e-mails for weeks on end. It was pointed out to me recently that working within in academia is hard. Of course most of us know that, I know that. But this person compared it to their line of work and how the insane tempo that we have would no

IDENTIFYING DRIVERS AND MECHANISMS OF CLIMATE-RELATED TREE MORTALITY Tree mortality is of high concern globally, and may be exacerbated by an increasing frequency and intensity of meteorological extremes such as droughts and heat waves. Although tree dieback events have been studied in many parts of the world, and are increasingly detectable through high- resolution remote sensing as well as surve

Lead-based perovskite nanocrystals (NCs) have outstanding optical properties and cheap synthesis conferring them a tremendous potential in the field of optoelectronic devices. However, two critical problems are still unresolved and hindering their commercial applications: one is the fact of being lead-based and the other is the poor stability. Lead-free all-inorganic perovskite Cs3Bi2X9 (X=Cl, Br,

This paper deals with the role of a journal's publisher country in determining the expected citation rates of the articles published in it. We analyze whether a paper has a higher citation rate when it is published in one of the large publisher nations, the U.S., U.K., or the Netherlands, compared to a hypothetical situation when the same paper is published in journals of different origin. This wo

Solar cells based on conjugated polymer and fullerene blends have been developed as a low-cost alternative to silicon. For efficient solar cells, electron-hole pairs must separate into free mobile charges that can be extracted in high yield. We still lack good understanding of how, why and when carriers separate against the Coulomb attraction. Here we visualize the charge separation process in bul
