In the age of high-resolution spectroscopic stellar surveys of the Milky Way, the number of stars with detailed abundances of multiple elements is rapidly increasing. These elemental abundances are directly influenced by the evolutionary history of the Galaxy, but this can be difficult to interpret without an absolute timeline of the abundance enrichment. We present age-abundance trends for [M/H],
New military technologies are animated by fantasies of perfect knowledge, lawfulness, and vision that contrast sharply with the very real limits of human understanding, law, and vision. 'War and Algorithm' look at the increasing power of algorithms in these emerging forms of warfare from the perspectives of critical theory, philosophy, legal studies, and visual studies. Together, the contributions
The effect of histamine on progesterone synthesis and cyclic adenosine 3',5'-monophosphate (cAMP) accumulation was studied in superfused and incubated follicles dissected free from immature rats treated with pregnant mare serum gonadotrophin (PMSG). Histamine, like LH, increased the progesterone synthesis, but to a smaller extent. The H2-antagonist, cimetidine, inhibited completely the histamine-i
Ett landskapsperspektiv krävs för att effektivt bevara biologisk mångfald och gynna ekosystemtjänster, eftersom de bakomliggande ekologiska processerna sker på rumsliga skalor som är större än enskilda fält och gårdar. Genom att förstå dessa processer bidrar forskningsmiljön SAPES och associerade forskningsprojekt till att visa värdet av att lantbrukare samarbetar för att gemensamt gynna ekosystem
Klimatförändringarna gör att de skånska landekosystemen står inför stora förändringar, på grund av direkta klimateffekter samt som en följd av förändringar i skötsel och markanvändning som ett resultat av samhällets klimatanpassnings- och utsläppsminskningsåtgärder. Förlust av biologisk mångfald riskerar att öka ekosystemens sårbarhet gentemot klimatförändringarnas effekter. Förebyggande arbete
Experimental studies are carried out to investigate the heat transfer characteristics involving an impinging jet with a shallow-angle in a crossflow. A rib is applied to control the jet impingement heat transfer Liquid crystal technique is employed to measure the wall temperature and obtain the heat transfer coefficients. In the study, the Reynolds number for the crossflow is 80,000 and the Reynol
In this thesis I have studied factors that regulate submerged macrophyte abundance, morphology and distribution in shallow eutrophic lakes, and how submerged macrophytes may affect the ecosystem. Light attenuation through the water column (turbidity and water depth) is probably not the most important factor regulating the distribution of submerged vegetation in macrophyte dominated shallow eutroph
Computerized systems to localize specific patterns appearing in ECG signal, such as the QRS complex and T wave usually utilize predefined templates. Where the signal is not clean, such as during atrial fibrillation (AF), analysis based on self-similarities of the ECG signal appears to be more stable. The authors describe a software package which uses self-similarity techniques to allow the subtrac
Abstract The objective of this investigation was to characterise the immunomodulatory or immunosuppressive effects of single drug treatment and the potential synergistic or additive effects of combined treatment with the focus on ciprofloxacin, thalidomide, mycophenolate mofetil, azathioprine, cyclophosphamide or leflunomide added to cyclosporin A (CyA). A rat cardiac transplant model was used to
In this paper, we explore the significant challenges relating to investment in IT in business. Information technology does not in itself deliver business value. We highlight the complexities that are often ignored in management of IT projects. If the management system in an organization is ineffective, then installing information technologies does not constitute a ‘magic wand’ that will generate p
Eight laboratories participated in a concerted research project on the assessment of hot working conditions. The objectives were, among others, to co-ordinate the work of the main European research teams in the field of thermal factors and to improve the methods available to assess the risks of heat disorders at the workplace, and in particular the “Required Sweat Rate” model as presented in Inter
The serine protease tissue-type plasminogen activator (t-PA) is involved in both vital physiological brain processes, such as synaptic plasticity, and pathophysiological conditions, such as neurodegeneration and ischemic stroke. Recent data suggest that epigenetic mechanisms play an important role in the regulation of t-PA in human endothelial cells. However, there are limited data on epigenetic r
Cerebral malaria (CM) is a life-threatening complication of Plasmodium falciparum infection. The pathogenesis of CM is complex. Cerebral metabolic dysfunction is implicated in CM, which may be caused by both an impaired cerebral microcirculation and a dysregulated inflammatory response affecting cellular respiration of mitochondria. Recombinant human erythropoietin (rhEPO) is a promising new thera
We wanted to test whether living environment, occupation and social position are risk factors for asthma and chronic bronchitis/emphysema (CBE). The prevalence of bronchial asthma, CBE, respiratory symptoms and smoking habits in a random sample of 12,071 adults aged 20-59 years was assessed in a postal survey with a slightly modified questionnaire previously used in central and northern Sweden (Th
This paper deals with optimal load balancing in telecommunication networks based on multiple spanning tree routing. This is the case in switched Ethernet networks where the operator configures different routing spanning trees and assigns each demand VLAN to one of the spanning trees. We consider modeling and solving three load balancing objectives: (i) minimization of the average link load with a
Context: Weight-based growth hormone (GH) dosing results in a wide variation in growth response in children with GH deficiency (GHD) or idiopathic short stature (ISS). Objective: The hypothesis tested was whether individualized GH doses, based on variation in GH responsiveness estimated by a prediction model, reduced variability in growth response around a set height target compared with a standar
