Background and Objective: Glioblastoma multiforme is a highly malignant primary brain tumor. It has no border but at best a marginal zone, however, invisible to the surgeon. An optical touch pointer (OTP) enabling differentiation of healthy and tumor tissue by means of fiber-optic fluorescence spectroscopy has been developed. In combination with an ultrasonic navigation system, the OTP may be used
OBJECTIVES: The aim of the study was to evaluate glucose levels and insulin secretion early in pregnancy and at a time when gestational diabetes mellitus frequently occurs in order to define reference values for glucose tolerance during pregnancy. The results were also related to maternal factors that might identify subjects at risk of developing gestational diabetes mellitus as well as foetal fac
Oleaginous microorganisms provide an opportunity to produce oils without the use of arable land for cultivation of oil-containing plants. Oleaginous microorganisms are also capable of storing products of pharmaceutical interest alongside storing polymers, which could open new opportunities in the bioplastic industry. Oily yeasts have several advantages in comparison to alternatives; their doubling
Fund companies and banks argue that letting them manage one’s money is a wise decision. They argue that they are able to create substantial growth in value for the investor without requiring any other input than a small fee and an amount to be invested. This essay tests this claim in a two folded analysis. Time series data with historical value developments of 24 out of the 30 largest Swedish equ
The purpose of this study is to compare the different short-term interest rate models, and to identify the better model within multiple countries. We selected three different types of data from the United States, the United Kingdom, and New Zealand. We compare the models with the historical data within these three countries, and figure out whether different countries could have their own best mode
Idag byggs det oerhört mycket. Nyproducerade bostäder konstrueras samt att äldre byggnader renoveras. Då är det viktigt att inte den större fokusen ligger på den ekonomiska- och ekologiska hållbarheten, utan även på den sociala hållbarheten. Detta för att förebygga ett segregerat samhälle som vi idag ser resultat av och drivs emot. Genom gemensamma bostadsgårdsytor skapar vi nya samlingsplatser. DToday, a lot is being built. New constructed homes are being constructed and older buildings renovated. It is important that the greater focus is not only on economic and ecological sustainability, but also on social sustainability. This is to prevent a segregated society that we today see results from and are driven by. Through joint housing estates we create new collection sites. This increases
Ammoniak (NH3) avgår från grisars gödsel och bidrar till övergödning och försurning. I Sverige avgår ca 47 % av grisproducenternas totala ammoniakutsläpp från verksamheternas stallbyggnader. Ny miljölagstiftning under industriutsläppsdirektivet kommer att ställa krav på att grisproducenterna använder tekniker som anses vara Bästa Tillgängliga Teknik (BAT). I BAT 30 anges de tekniker som anses varaAmmonia (NH3) is produced and emitted from pigs’ feces and urine. Atmospheric ammonia can cause eutrophication and acidification of ecosystems. New environmental legislations under the Industrial Emission Directive, passed by the European Commission, will demand pig producers to use techniques that are considered Best Available Techniques (BAT) to reduce ammonia emissions from pig houses. The new
Kraftringens geotermianläggning i Lund har varit i drift sen 1984. Det är den enda stora geoter-miska anläggningen i Sverige. Efter mer än 30 års drift är det dags att utvärdera hur det har fungerat. Arbetet be-skriver de geologiska förutsättningarna som stratigrafi (formation), formationstemperatur, typ av akvifer, porositet, permeabilitet och vattenkemi, samt driftdata, systemuppbyggnad, funktioThe geothermal heat plant in Lund has been running since 1984. It is the only one of its kind in Sweden. After running for more than 30 years it’s now time to evaluate the experiences from the long operational period of the heat plant. This report describes the geological conditions like the formation, temperature of the geothermal water, aquifer, porosity, permeability, and chemistry of the forma
Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale
Quantum annealing provides a promising avenue for obtaining good approximate solutions to difficult optimization problems. Protein folding represents one such problem. For testing novel algorithms and technologies, simplified lattice models are well suited, as they represent considerable computational challenges despite their simplicity. One such model is the HP model, where the protein is represe
The aim of this paper is to study the extent to which non-Annex I countries are implementing or exploring select actions that support both climate change mitigation and sustainable development objectives in the energy sector. The research is based on a survey of the national communications of 100 non-Annex I Parties to the UNFCCC. Although national communications are intended to provide informatio
Hedersrelaterat våld och förtryck blev känt i Sverige under 1990-talet, då de första uppmärksammade hedersmorden begicks i landet. Morden på Sara, Pela och Fadime väckte stor debatt i Sverige och man försökte hitta förklaringar till hur detta kunde inträffa och framförallt varför. Hedersrelaterat våld skiljer sig från andra våldsformer mot kvinnor på ett flertal sätt. Det som är viktigt att framHonour-related violence and oppression became known in Sweden during the 1990s, when the first high-profile honour murders were committed in the country. The murders of Sara, Pela and Fadime raised an intensive debate in Sweden and we tried to find explanations for how this could have happened, and above all why. Honour-related violence differs from other forms of violence against women in severa
Sverige och Danmark anses i komparativa sammanhang tillhöra samma rättsfamilj. I arbetsrättsligt avseende skiljer sig Danmark från övriga nordiska länder på så sätt att man undvikit lagstiftning i mesta möjliga mån och t.o.m. överlåtit implementering av vissa EU-direktiv åt arbetsmarknadens parter genom kollektivavtal. Den lagstiftning som finns är spretig och i stor utsträckning införd p.g.a. EU-In a comparative context Sweden and Denmark are often considered part of the same families of law. In respect of labour law, Denmark differs from the other Nordic countries by avoiding legislation as much as possible and have even left implementation of some EU directives to be performed through collective agreements. The legislation is uneven and to a great extent introduced after demands from th
Lignin, the world's most abundant biopolymer with high aromaticity, has huge potential as a renewable feedstock replacing petroleum for the production of chemicals, fuels and functional materials. The enhanced utilization of lignin would improve the economic viability of existing pulp and paper mills, as well as lignocellulosic biorefineries, where lignin is highly available, but mostly incinerate
Background and purpose — First-line treatment (education, exercise) for patients with hip and knee osteoarthritis (OA) aims to reduce pain and improve function. We aimed to compare progression to joint replacement within 5 years between responders and non-responders to first-line treatment for hip and knee OA, respectively. Methods — This observational study included data for 30,524 knee OA and 13
AIM: We aim to compare machine learning with neural network performance in predicting R0 resection (R0), length of stay > 14 days (LOS), major complication rates at 30 days postoperatively (COMP) and survival greater than 1 year (SURV) for patients having pelvic exenteration for locally advanced and recurrent rectal cancer.METHOD: A deep learning computer was built and the programming environment
Valgus slipped capital femoral epiphysis (SCFE), is rare. This study describes the diagnosis, treatment and outcome of valgus SCFE in Uruguay. The medical records and radiographs were reviewed in eight consecutive children [mean age 11.9 years (range 9-13; six female)] with valgus SCFE between 1997-2017. In 2018-2019, all patients were reexamined clinically, new radiographs obtained, and patient-r
The common pathogen Group A Streptococcus (GAS, Streptococcus pyogenes) is an extracellular bacterium that is associated with a multitude of infectious syndromes spanning a wide range of severity. The surface-exposed M protein is a major GAS virulence factor that is also target for protective antibody responses. In this study, we use a murine immunization model to investigate aspects of the cellul
Shunting yards are one of the main areas impacting the reliability of rail freight networks, and delayed departures from shunting yards can further also affect the punctuality of mixed-traffic networks. Methods for automatic detection of departures, which are likely to be delayed, can therefore contribute towards increasing the reliability and punctuality of both freight and passenger services. In
