Optical investigations on particles evolution and flame properties during pulverized coal combustion in O 2 /N 2 and O 2 /CO 2 conditions

The evolution of soot and coal/char as well as the flame properties, during pulverized coal combustion in O 2 /N 2 and O 2 /CO 2 conditions, were experimentally studied using optical diagnostics. The jet flames of pulverized coal particles were produced by using an entrained-flow reactor with optical access, and the oxygen concentrations of the gas carrying pulverized coal particles were vari

I den offentlege debatten om høgare utdanning er undervisarane påfallande fråverande. Dei sterkaste stemmene tilhøyrar politikarane, studentane, institusjonsleiarane og pedagogane. Når undervisarane melder seg på er det oftast i ein klagesong over høgt arbeidspress, krevjande studentar og mangel på tid og ressursar til forsking. Kvifor oppfattar brorparten av undervisarar i høgare utdanning undervI den offentlege debatten om høgare utdanning er undervisarane påfallande fråverande.

Reliability of the point-of care analyzer “StatStrip® Xpress™” for measurement of fetal blood lactate

Objectives: Measurement of lactate in fetal blood is used to assess the degree of anaerobic metabolism. The technical difficulties in obtaining enough scalp blood for analysis by a bloodgas-analyzer advocates for the use of a point-of-care device. StatStrip®Xpress™ (SSX) has shown promising properties but needs further evaluation before implementation into fetal surveillance. Methods: Arterial/ve

Physiological characterization and sequence analysis of a syringate-consuming Actinobacterium

Hardwood lignin is made of up to 75% syringyl-units and the bioconversion of syringate and syringaldehyde is therefore of considerable interest for biological valorization of lignin. In the current study, we have isolated a syringate-consuming bacterium identified as Microbacterium sp. RG1 and characterized its growth on several lignin model compounds. Growth was observed on syringate, 3-O-methyl

Regulating European Standardisation through Law : The Interplay between Harmonised European Standards and EU Law

Standardisation is one of the oldest human activities. Industrial revolution and electro-technical advancements have further increased the importance of standardisation. Nowadays standards regulate our daily life not only through the products and services we use, but also directly as laws. In the EU, Harmonised European Standards (HESs) are used in legislation—occupying the law’s domain—but at the

Characterisation of non-coagulating milk and effects of milk composition and physical properties on rennet-induced coagulation in Swedish Red Dairy Cattle

Non-coagulating milk is a serious problem in the cheese industry, since it decreases cheese yield, resulting in decreased economic output. This study evaluated rennet-induced coagulation properties and composition of milk from individual Swedish Red Dairy Cattle. Milk samples from 679 individual cows were rheologically evaluated, of which 18.1% of the cows produced non-coagulating milk and 18.9%

Trade-offs with longer lifetimes? The case of LED lamps considering product development and energy contexts

Longer product lifetimes are promoted by the EU's Circular Economy Action Plan, but incentivising longer lifetimes could also result in trade-offs between different environmental impacts for some product categories. LED lamps are still experiencing improvements in efficacy and material design, which raises questions about whether longer lifetimes are desirable from an overall environmental perspec

Bacteria constrain the fungal growth response to drying-rewetting

Bacteria and fungi are the two principal decomposer groups in soils, determining rates of biogeochemical cycling. Rewetting of dry soils induces enormous dynamics in biogeochemistry. Bacteria have been shown to exhibit large variation in growth over time upon drying-rewetting (D/RW), however, in studies to date, fungal growth has shown limited responsiveness. Here we investigated whether fungal gr

Läkaren som patient : En beskriven rollkonflikt

Flera studier har på senare år visat att den läkare som själv blir sjuk upplever sig försatt i en särskilt problematisk situation. Ett sätt att öka förståelsen för den sjukdomsdrabbade läkarens upplevda dilemma kan vara att närstudera läkares sjukdomsnarrativ. I denna artikel uttolkas tre skriftliga vittnesmål av läkare med morfinmissbruk, med särskild tonvikt på Michail Bulgakovs semifiktiva nove

Medicinhistoria i Lund : En kort översikt

Lunds historia innehåller många medicinhistoriska händelser. Medicinhistoria som akademisk disciplin är dock inte endast deskriptiv utan även analyserande. Flera institutioner vid Lunds universitet bedriver medicinhistorisk forskning från olika utgångspunkter. Medicinhistoria är ett viktigt ämne för förståelsen av dagens medicin och denna översikt vill visa varför och hur ämnet behandlas vid Lunds

The contact angle of nanofluids as thermophysical property

Droplet volume and temperature affect contact angle significantly. Phase change heat transfer processes of nanofluids – suspensions containing nanometre-sized particles – can only be modelled properly by understanding these effects. The approach proposed here considers the limiting contact angle of a droplet asymptotically approaching zero-volume as a thermophysical property to characterise nanofl

Patientens röst - den patografiska genren i historisk belysning

’Patografi’ är beteckningen på en relativt ung och snabbt växande litterär genre. Syftet med denna artikel är att introducera den patografiska genren och att lämna ett bidrag till förståelsen av dess historiska uppkomst. Tre omvälvningar i skolmedicinen vid 1800-talets slut och 1900-talets början lyfts fram som betydelsefulla för den patografiska genrens framväxt: sanatoriernas tillkomst, stigmati
