Shear banding in sand is an emergent fine-scale mechanism whose characteristic length scale is only a few particles. X-ray scanning a sand specimen under loading allows the analysis of the kinematics of individual grains and grain contacts during deformation. This paper summarises results from one such test performed on Hostun sand, and discusses some key issues that must be addressed in order to

The new NERICA upland rice varieties were developed in Africa for Africa so as to address the continental-wide rice cereal challenge, poverty and food insecurity. To date, the ‘success’ of the dissemination of NERICA amongst smallholder farmers has mainly been established econometrically by measuring production growth or household income gain. This type of analysis allows for capturing shifts in i

Benchmarking is a powerful strategic tool used to assist decision makers to improve the quality and effectiveness of organisational processes. Even in Higher Education nowadays, benchmarking is used as a tool for quality enhancement. This paper explores the results from a study on international benchmarking on elearning in higher education. The study explicitly showed the value and impact of the m

Abstrakt Bakgrund: Allt flera människor flyr från sitt hemland pga. krig, hot eller förföljelse, de söker skydd hos mottagande land. Papperslösa personer tillhör dessa grupp av människor, de är en extremt utsatt grupp bland Europas befolkning både inom vården och bland allmänheten. De får oftast ojämlikt vård och riskerar därför att få sämre hälsoutfall jämfört med resten av befolkning. MajoriteteAbstract Background: An increasing number of people are fleeing their home countries due to war, threats, or persecution, seeking refuge in host countries. Undocumented individuals are part of this group, constituting an extremely vulnerable population in Europe, both in healthcare settings and among the public. They often receive unequal treatment and are at risk of poorer health outcomes compare

Vidhäftning är ett fenomen som naturligt uppstår i livsmedelsindustrin. Fenomenet uppstår främst då livsmedelsprodukter klibbar sig fast och fäster till ytor i processutrustning. I flera fall kan vidhäftning vara till god nytta till exempel som en sensorisk aspekt, men i livsmedelsindustrin kan fenomenet utgöra en nackdel. Tetra Pak har i ett projekt tillsammans med Lunds Tekniska Högskola utveckStickiness of different food products on surfaces can occur naturally during food filling in Tetra Recart form- and seal machines. The aim of this thesis was to develop a model and an adhesion test method for determining and understanding this stickiness. More specifically for the food products whole peeled tomatoes, sliced mushrooms, mandarin chops and peach halves on stainless-steel. Additionall

Cancer överkommer kroppens immunförsvar och andra tumör-bekämpande system, bland annat genom att öka eller minska uttrycket av vissa gener. Gener som är viktiga för cell-cykelprogressionen är ofta påverkade. Till exempel är genen wee1 ofta överuttryckt i cancer. wee1s funktion är att koda för ett protein som förhindrar att cellen fortsätter i cellcykeln om den har trasigt DNA. Ett förslag på canceIn this study the yeast S. pombe is used to try to find genes which can (potentially in the future) be targeted in cancer cells to stop the cells from growing. WEE1 is a kinase important for proper cell-cycle progression, as it inhibits cyclin-dependent kinases activity. It is overexpressed in many cancers and many studies are being done researching how WEE1 inhibitors can be used as a cancer trea

PUS7 role in cellular adaptation to metabolic stress When we hear the word metabolism, our minds often jump to calories and diets. Cellular metabolism however refers to all essential mechanisms that keep our body up and running. Unsurprisingly, complex networks navigate this sensitive system, with many pathways that allow adaptation to changing and stressful environments. If this delicate balance

The EU ETS was the first international policy instrument to introduce regulation of CO2 emissions of pulp and paper companies with installations in Europe. Out of 11, 500 installations introduced to the system about 900 were pulp and paper mills. In terms of allocated emission allowances (EUAs) the pulp and paper industry (hereafter PPI) represents two per cent of the EU ETS (Hyvärinen 2005: 40).

Background: Urosepsis is a life-threatening condition that needs to be addressed without delay. Two critical issues in its management are: (1) Appropriate empirical antibiotic therapy, considering the patients general condition, comorbidity, and the pathogen expected; and (2) Timing of imaging to identify obstruction requiring decompression. Objectives: To identify risk factors associated with 30-

Evaluating soil strength by geophysical methods using P-waves was undertaken in this study to assess the effects of changed binder ratios on stabilization and compression characteristics. The materials included dredged sediments collected in the seabed of Timrå region, north Sweden. The Portland cement (Basement CEM II/A-V, SS EN 197-1) and ground granulated blast furnace slag (GGBFS) were used as

Background and purpose - Hip surveillance in children with cerebral palsy (CP) includes repeated radiographic hip examinations and measurements of the hip migration percentage (MP) to identify hips in need of surgery early, to prevent dislocation with the fewest number of radiographic examinations possible. We analyzed the early development of the MP in hips operated on to prevent hip dislocation

Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory joint disease that affects all aspects of life. Rheumatology care strives to achieve optimal health based on person-centred care (PCC). Effective treatment is available, but patients still experience unmet needs.Aims: The overall aim of this thesis was to explore patients' perspectives of PCC and preferred outcomes in early RA. Specifi

The burden of depression and anxiety disorders is greater in women, and female sex hormones have been shown to affect mood. Psychological side effects of hormonal contraception (HC) are also a common complaint in the clinic, but few previous studies have investigated this subject. We therefore wanted to investigate whether use of HC was associated with adverse psychological health outcomes, and wh

Naturliga fiender för bladlöss i äppelodlingar Det finns en stor mångfald av insekter i vår omgivning. De insekter som man främst kanske tänker på är de olika skadeinsekter som finns i jordbrukslandskapet. Det här är kanske främst påtagligt för olika jordbrukare som får handskas med flera olika skadeinsekter innan de kan bärga sin skörd, men alla som har odlat något har troligen haft något proble

BACKGROUND Marked changes have occurred in in vitro fertilization (IVF) methodology during the past 25 years but also in characteristics of couples undergoing treatment. METHODS This study was based on 27 386 women undergoing IVF treatment from 1982 to 2006 and giving birth to 31 850 infants. Outcomes of deliveries were studied using Swedish health registers. Comparisons were made with all deliver
