Two global optimization methods based on Genetic Algorithms (GA) and Shuffled Complex Evolution (SCE-UA) method were examined to evaluate reaction terms in a reactive solute transport model involving cation exchange reactions. Although the both algorithms can minimize the objective function after succession of generations, SCE-UA method appears superior to GA in that its performance depends less o
In a costal aquifer, saltwater intrusion is frequently observed due to an excess exploitation. There are many researches focused on the saltwater intrusion. However, there are few researches, which take into consideration the mixing processes in a stratified heterogeneous aquifer. In the present study, a laboratory experiment and numerical simulation are made in order to understand the phenomena i
In general, a natural aquifer has a hydrogeologically non-uniform structure. The movement of pollutants in groundwater is affected by such structural properties during transport by local advection and microscopic dispersion. The macroscopic dispersion coefficient increases linearly with travel distance or travel time at the initial stage after the pollutant is released, and then converges asymptot
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
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
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
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
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
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
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.
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
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 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
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
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
[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
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
