Numerical study of non-reactive tracer transport in a heterogeneous field, with random microscopic dispersivity

One of the most important processes for the groundwater environment is macroscopic dispersion in geological media. In this study, laboratory experiments and numerical simulations are carried out in order to understand the transport of a non-reactive tracer in a heterogeneous porous medium. The method of characteristics and the implicit finite difference method are employed for numerical solutions

Domkyrkoentreprenaden : förspel, genomförande och avslutning

En berättelse om entreprenaden bakom byggandet av Lunds domkyrka. Den lokala aristokratins erfarenhet av entreprenader, anskaffandet av arbetskraft och Harald Blåtands första etablering i Lund inleder redogörelsen. Den första byggnaden på kyrkoplatsen, troligen ett kloster, får byggnadsmaterialet fråm Helsingborg- och Ystadstrakten. Den stående domkyrkans sten kommer från Hallaröd/Munkarp. En fyll

Lilla Harrie och stora Örtofta : Dynamik och divergens. Två byar i Harjager

De två byarna har samma geologiska och näringstekniska förutsättningar. Lilla Harrie var en "normal" by med ett bofast frälse och ett antal gårdar fram till 1300-talet medan Örtofta uppstod på direktiv av kyrka/kung omkring 1100 då en kyrklig aristokrati etableras, sannolikt som vägförvaltare för den väg och bro där stenen till Lunds domkyrka transporteras. Det kyrkliga frälset övergår i ett värld

Frosta : Mittens härad och Saxes röjning

Under 1100-talet började allmänningsskogarna i skåne att koloniseras. Östra Sallerup- Saxildrup Ruma- är en kolonisationstrakt. Någon av Hvide familjen vid namn Saxo eller liknande fick domänen och engagerade nio stormän som medkolonisatörer. En kyrka byggdes då kolonisterna var många nog. I kyrkan gjordes bland annat en kalkmålning vars enda kända samtida motsvarighet finns som en mosaik i klostr

Follow-up on: optimizing lesion detection in small bowel capsule endoscopy and beyond: from present problems to future solutions

Introduction: This review presents noteworthy advances in clinical and experimental Capsule Endoscopy (CE), focusing on the progress that has been reported over the last 5 years since our previous review on the subject. Areas covered: This study presents the commercially available CE platforms, as well as the advances made in optimizing the diagnostic capabilities of CE. The latter includes recent

Overcoming the fear of making a crappy sketch

This paper discusses which freehand drawing skills a designer needs in the 21st century and why not more people are using sketching as a creative tool. Are design schools teaching the adequate skills needed today? In the past 5-10 years focus has shifted from product design to experience design and the skills needed to make high end drawings might not be needed to the same extent. 3D computational

Genetic characterization of amyloid-β and tau network spread

Protein-specific and shared genetic pathways influence the spread of amyloid-β and tau pathology. Hence, distinct gene expression profiles may induce regional vulnerability of the human cortex to the specific proteinopathies of Alzheimer’s disease.

Gravkistor från domkyrkoområdet till tiden omkring 970 visar att Harald Blåtand var stadens grundare. Med georadar har en fyrsidig anöäggning, troligen ett kloster från 1040-talet, påvisats under den nuvarande domkyrkan. Stenen till byggnaden kom från Helsingborgs- och Ystadstrakten.

Using microworlds to study critical infrastructure protection—the effect of incentives on risk management

A computer simulated microworld was used to study risk management in a critical infrastructure context. 36 students assumed the role of an electric distribution company Chief Executive Officer (CEO) making decision on how to spend resources between investments in risk reduction and other investments. We studied the effect of differences in terms of the incentives to invest in risk reduction and th

Αν και η αρχαία ελληνική αποτελούσε βασικό μάθημα στο Πανεπιστήμιο Lund από την αρχή της λειτουργίας του, η διδασκαλία της Νέας Ελληνικής ξεκίνησε το 1957 υπό την επίδραση του αυξανόμενου ενδιαφέροντος για τη νεοελληνική λογοτεχνία και της ανάγκης εκπαίδευσης των Σουηδών αρχαιολόγων με αντικείμενο έρευνας την Ελλάδα. Το Τμήμα Νεοελληνικών Σπουδών του Πανεπιστημίου Lund, έχοντας πλέον αυτονομηθεί α

GDNF-mediated rescue of the nigrostriatal system depends on the degree of degeneration

Glial cell-line derived neurotrophic factor (GDNF) is a promising therapeutic molecule to treat Parkinson’s disease. Despite an excellent profile in experimental settings, clinical trials testing GDNF have failed. One of the theories to explain these negative outcomes is that the clinical trials were done in late-stage patients that have advanced nigrostriatal degeneration and may therefore not re

Omkring 1080 påbörjades den ännu stående kyrkan. Arbetet utfördes sannolikt till stor den av slavarbetskraft, stenen kom från Hallaröd/Munkarpområdet och kördes längs en väg, vars spår ännu syns i landskapet. En stor del av artikeln behandlar slavar, slavhandel och slavsamhälets upphörande den därmed sammanhängande kolonisationen av Skånes allmänningsskogar

Allelopathy in bryophytes - a review

Allelopathy in bryophytes shapes ecosystems by influencing the species composition of both vascular plants and other bryophytes. Several allelopathically active chemicals in bryophytes have been discovered since the latter half of the 20th century and laboratory studies have showed their inhibiting impact on germination, growth and establishment of surrounding plants. However, other studies failed

Heart filling exceeds emptying during late ventricular systole in patients with systolic heart failure and healthy subjects – a cardiac MRI study

Background: Total heart volume (THV) within the pericardium is not constant throughout the cardiac cycle and THV would intuitively be lowest at end systole. We have, however, observed a phase shift between ventricular outflow and atrial inflow which causes the minimum THV to occur before end systole. The aims were to explain the mechanism of the late-systolic net inflow to the heart and determine

Can routine outpatient follow-up of patients with bladder cancer be improved? A multicenter prospective observational assessment of blue light flexible cystoscopy and fulguration

Background: The aim of this prospective cohort study was to determine the feasibility of incorporating blue light flexible cystoscopy (BLFC) and biopsy/fulguration into routine outpatient follow-up of non-muscle invasive bladder cancer patients. Methods: The study included patients with non-muscle-invasive bladder cancer (NMIBC) who were scheduled for routine follow-up. Hexaminolevulinate was inst

Preliminära resultat från registrering av sporkapslar i inventeringen av Skånes mossor

[Preliminary results from bryophyte spore capsule records in the county of Skåne, southernmost Sweden] Occurrences of sporophytes are recorded by inventorers within the bryophyte flora project for Skåne. Here we present commented distribution maps with sporophyte presence/absence indicated for Calliergonella cuspidata, Dicranum scoparium, Encalypta streptocarpa, Homalothecium sericeum, Hylocomium

Removal of UHT dairy fouling — An efficient cleaning process by optimizing the rate controlling alkaline cleaning step

A rigid mineral-based deposit, termed ultra-high temperature (UHT) fouling, is formed on heat exchanger surfaces during milk processing at 140 °C. The removal of this type of fouling is for the first time assessed using a laser triangulation sensor and a camera, to measure changes in the thickness and to visualize structural changes in the fouling in situ. The process was monitored during both the

High-density and targeted glycoproteomic profiling of serum proteins in pancreatic cancer and intraductal papillary mucinous neoplasm

Objective: Glycoproteomics is an emerging subfield of proteomics. Tumor-specific variations in protein glycosylation might be potential targets for the development of new cancer diagnostics. Here, we performed high-throughput screening and targeted verification of glycome alterations in serum samples from patients with pancreatic cancer and the precancerous lesion intraductal papillary mucinous ne

Intestinal metaplasia at the gastroesophageal junction is associated with gastroesophageal reflux but not with Helicobacter pylori infection

Objective: Studies of the etiology of intestinal metaplasia (IM) at a normal appearing gastroesophageal junction (GEJ) are conflicting as associations with both H. Pylori (HP) infection and gastroesophageal reflux has been reported. The aim of this study was to investigate whether IM at the GEJ is associated with gastroesophageal reflux or HP infection. Material and methods: Fifty asymptomatic vol

A framework for aggregating risk information across organisational levels—the case of Swedish municipalities

Performing risk assessments for hierarchical, multi-functional systems, such as a municipality, is an activity that requires input from a multitude of actors. In such systems risk assessments can be performed at many system levels and support different types of decisions. For issues that are constrained to a specific sub-system, such as a municipal department, decisions can be preferably taken at
