The acquisition of multispectral x-ray images and the treatment of such data are essential for understanding many devices that we encounter in everyday life. Examples include computerized tomography in hospitals and scanners at airports. X-ray devices remain impractical for undergraduate laboratories because of their considerable cost and the risk of exposure to ionizing radiation. One way to acqu
Background Leaf-cutting ants live in symbiosis with a fungus that they rear for food by providing it with live plant material. Until recently the fungus' main inferred function was to make otherwise inaccessible cell wall degradation products available to the ants, but new studies have shed doubt on this idea. To provide evidence for the cell wall degrading capacity of the attine ant symbiont, we
Methods: aEuro,Patients with cataract (n == 493) and controls (n == 142) were analyzed for the UCHL1 p.S18Y polymorphism using dynamic allele-specific hybridization. Results: aEuro,Significant differences were observed in allele and genotype frequencies of the p.S18Y polymorphism between controls and cataract patients, where a positive UCHL1 allele A carrier status was associated with the cataract
The Nordic countries have a quite different urban structure and social systems than the USA. Denmark, Finland, Norway and Sweden may then constitute a critical test of the empirical reach of Richard Florida's much cited creative class thesis beyond its empirical basis in the USA. This paper employs comparative statistics to examine the importance of the quality of place in attracting members of th
The ruptured anterior cruciate ligament (ACL) leads to immediate symptoms that severely affect the individual and receives great attention among the scientific community, yet there is still no consensus on the optional form of treatment. An ACL injury is also a well known high risk factor for the development of knee osteoarthritis (OA) some decades later. Knee OA development after an ACL injury is
Purpose – The purpose is to describe the advantages, challenges and uncertainties of collecting and analyzing data using participant observation in logistics research. Design/methodology/approach – Experiences from a participant observation study of an interorganizational RFID implementation in an international environment are presented and reflected on. The RFID implementation included complex in
Insertion of metals into various tetrapyrroles is catalysed by a group of enzymes called chelatases, e.g. nickel, cobalt, magnesium and ferrochelatase. It has been proposed that catalytic metallation includes distorting the porphyrin substrate by the enzyme towards a transition state-like geometry in which at least one of the pyrrole rings will be available for metal chelation. Here, we present a
Popular Abstract in Swedish Sammanväxningar i buken är en normal reaktion efter skador i bukhinnan och utvecklas efter ett inflammatoriskt svar och det efterföljande läkningsförloppet. Många sammanväxningar bildas inom 24-48 timmar efter skadan och tillbakabildas normalt efter 5-7 dagar. Många av de sammanväxningar som kvarstår kan ses som en obalans i de system som bildar ärr (fibros) och löser dIntraabdominal adhesions are formed after most operations and a limited number of studies have to examine the long-term spectrum of adhesion-related disorders and the cost associated with this. Only a few numbers of antiadhesive agents are available which, however, do not decrease the actual morbidity that follows intraabdominal adhesions, such as small bowel obstruction, infertility and pain. Fut
Clinically, hemodilution to a hematocrit of 9% has been studied, but the effects of hypovolemia during this degree of hemodilution have not been elucidated. We studied the response to blood loss during extreme hemodilution and evaluated indicators of hypovolemia. Systemic and myocardial hemodynamics, oxygen transport, and blood lactate concentrations were measured in 12 anesthetized pigs exposed t
1 The endocannabinoid anandamide is an emerging potential signalling molecule in the cardiovascular system. Anandamide causes vasodilatation, bradycardia and hypotension in animals and has been implicated in the pathophysiology of endotoxic, haemorrhagic and cardiogenic shock, but its vascular effects have not been studied in man. 2 Human forearm blood flow and skin microcirculatory flow were reco
Moving towards an ecologically sound society requires strong support from higher educational institutions. During the past decade, the Journal of Cleaner Production has published more than 150 articles that have highlighted advances in academic efforts on sustainability in higher education, that were focused upon education, research, outreach and greening of campus operations in universities from
This text deals with the phenomenon of today’s rune carvers in the Nordic area. By using symbols of antiquity in their craftsmanship, the rune carvers revive an act that is historically significant and bears aspects of identity in the past as well as today. Why do people carve and erect runes stones today? When and where is it done? What are the explicit or implicit purposes? The text tries to ans
Nasopharyngeal carcinoma (NPC) is common among southern Chinese including the ethnic Cantonese population living in Hong Kong. Epstein-Barr virus (EBV) infection is detected in all undifferentiated type of NPC in this endemic region. Establishment of stable and latent EBV infection in premalignant nasopharyngeal epithelial cells is an early event in NPC development and may contribute to its pathog
A number of measures have been taken by the society to ensure gender equality in higher education. Nevertheless, women still face great difficulties when pursuing an academic career. Our aim is to increase the understanding of how the society, conceptualised as the organisational field, interacts with organisational factors and personal actions as women try to establish themselves within academia.
Around 70,000 osteoporosis-related fractures occur in Sweden annually and approximately half of the women in western world will sustain a fragility fracture after the age of 50 years. Fracture preventive efforts require the identification of individuals who are at high risk. Biochemical markers of bone turnover (BTMs) have shown some degree of fracture predictability. There is also a correlation b
A systematic review of radiation therapy trials in several turnout types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for rectal cancer is based on data from 42 randomized trials and 3 meta-a
Popular Abstract in Swedish Anglo-amerikanska relationer efter andra världskriget bestod både av samarbete och konflikt. Ett exempel på det första var Pentagondiskussionerna 1947 då ett amerikanskt uttalande betonade det generella målet att upprätthålla säkerheten i Mellanöstern genom att stödja de brittiska politiska, ekonomiska och strategiska positionerna i området. Ett exempel på det senare va
The relative contribution of transcytosis vs. large pore transport to the passage of macromolecules across microvascular endothelia has been a controversial issue for nearly half a century. To separate transcytosis from 'porous' transport, the transcytosis inhibitors N-ethylmaleimide (NEM) and filipin have been tested in in situ or ex vivo perfused organs with highly conflicting results. In contin
Texture of potatoes with different shapes (slices and strips) were evaluated after frying and in some cases after baking. Blanched and unblanched potato slices (Bintje variety) were fried at four oil temperatures: 160, 170, 180 and 190C until reaching a moisture content of similar to1.7%. A puncture test with three point support for the slices was applied to measure the texture of potato chips usi
