A density functional theory of the spatial distribution and biaxial nematic order of polymers of arbitrary length and rigidity inside a spherical cavity is proposed. The local order of different chain segments is considered as an alignment to a spatially varying director field of cylindrical symmetry. The steric interactions are taken into account in the second virial approximation. Polymer densit
Using an experimental model of non-alcoholic (alimentary-induced) steatohepatitis in rats, we found that this pathological condition created by consumption of a special diet for 16 weeks results in a drop in the brain mass (by 22%, on average) and also in decreases in the size and morphological modifications of astrocytes and the level of a calcium-binding protein, S-100b. The latter shifts were g
Egyptology in the 19th and early 20th centuries developed simultaneously with increased imperial presence in Egypt by the European imperial powers, which would have influence on how the discipline was practised. The history of Egyptology has for this reason primarily focused on the big four – Great Britain, France, Germany and USA – and on Egypt itself. The aim of this study is to examine how Egyp
Enligt regelverken tillämpliga i icke-internationella väpnade konflikter, gemensamma artikeln 3 i Genèvekonventionerna samt tilläggsprotokoll 2, erbjuds skydd till civila som inte direkt deltar i strid. En gemensam definition av vad som anses vara direkt deltagande i strid existerar inte i tillämpliga traktat i den internationella humanitära rätten och inte heller förser nationell eller internatioThe regulations applicable in non-international armed conflicts, Common Article 3 to the Geneva Conventions I-IV and Additional Protocol II, offer protection to civilians who do not directly participate in the hostilities. There is no commonly accepted definition of direct participation in hostilities in treaty-based international humanitarian law, State practice or international jurisprudence.
Values are a crucial aspect of human–nature relationships, and they play important roles in policies on land use and environmental management. However, our current decision-making systems tend to take inadequate account of the diversity of values associated with human relationships with nature. Instrumental, monetary values dominate the political systems following the Western neoliberal hegemony.
When conflict is protracted, there can be a perception of impossibility regarding change of the situation towards peace or transformation as the conflict has defied this and persisted despite time and efforts. This study aims to investigate if and how imagination can be used in conflict transformation, despite this perceived impossibility, by applying a qualitative method and conducting a textual
This master thesis explores the mechanisms and optimization strategies of a pneumatic conveying system. By investigating the impact of process parameters on power consumption and erosion rate, the aim was to provide valuable insights for system design and operation. The research combines theoretical considerations, CFD simulations, and numerical calculations to analyse the behaviour of the system
This paper will examine if U.S. foreign aid to Colombia had any effect on unemployment rates in the country from 2000-2008. The anti-drug policy Plan Colombia’s success will be assessed and how the policy, which consisted of military and social aid, was able to reduce unemployment numbers. The analysis will be a case study using a qualitative method of interpreting trends from longitudinal and cro
In recent years, several men in Sweden have been acquitted of different sexual offences because the courts deemed that it could have occurred in their sleep. According to a leading expert, several of the Swedish acquitting cases are based on incorrect or irrelevant arguments and reasoning regarding sexsomnia. Therefore, it is important to gain a deeper understanding of how sexsomnia manifests with

De nationella avtalen med vetenskapliga förlag är under förändring. Det påverkar både tillgången till vetenskapliga artiklar och villkoren för publicering. Här får du en översikt över bakgrunden, vad som förändras och vad det kan innebära i praktiken. Avtal med vetenskapliga förlag – lästillgång och publiceringAnställda vid Lunds universitet har tillgång till vetenskapliga tidskrifter och möjlighe

This study quantitatively diagnose the linkage between Total Solar Irradiance (TSI) and Earth's near-surface air temperature (TAS) of past 1000-year as simulated by Paleoclimate Modeling Intercomparison Project 3 (PMIP3) models. The results demonstrate that there is causal feedback of TAS from TSI variations, especially in the tropical and subtropical regions. The consistency between models in sim
The angular distribution of photoelectrons ejected during the ionization of Ne atoms by extreme ultraviolet (XUV) free-electron laser radiation in the presence of an intense near infrared (NIR) dressing field was investigated experimentally and theoretically. A highly nonlinear process with absorption and emission of more than ten NIR photons results in the formation of numerous sidebands. The amp
Background. This study aimed to evaluate Pediatric Appendicitis Score (PAS), diagnostic delay, and factors responsible for possible late diagnosis in children <4 years compared with older children who were operated on for suspected appendicitis. Method. 122 children, between 1 and 14 years, operated on with appendectomy for suspected appendicitis, were retrospectively analyzed. The cohort was divi
The mevalonate pathway synthetizes cholesterol, steroid hormones, and non-steriod isoprenoids necessary for cell survival. 3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) is the rate-limiting enzyme of the mevalonate pathway and the target for statin treatment. HMGCR expression in breast tumors has recently been proposed to hold prognostic and treatment-predictive information. This study a
Popular Abstract in Swedish Cancer är ett samlingsnamn för flera hundra sjukdomar som har gemensamt att de har fått en okontrollerad celldelning till följd av genetiska förändringar. Celldelning sker ständigt i vår kropp när gamla celler måste bytas ut och nya kopior bildas. Vid dessa processer sker det ofta mutationer i vårt DNA så att informationen förändras, vilket resulterar i att skadan kopieNormal tissue is tightly controlled to keep a balance between reproduction and elimination of cells. In cancer, these regulated processes are disrupted, resulting in uncontrolled cell growth. Regulation of RNA stability and turnover is important to maintain cellular homeostasis and can be controlled by various mechanisms. During stress, the cell can form cytoplasmic complexes of proteins and RNAs,
Neuronal function depends on the properties of the synaptic inputs the neuron receive and on its intrinsic responsive properties. However, the conditions for synaptic integration and activation of intrinsic responses may to a large extent depend on the level of background synaptic input. In this respect, the deep cerebellar nuclear (DCN) neurons are of particular interest: they feature a massive b
The challenge of understanding how localized deformation modifies fluid flow in porous rock is addressed. New approaches are presented, based on neutron radiography and digital image analyses, to track fluid flow in rock specimens and to calculate flow velocity fields providing local flow measurements. The results show that neutron radiography, backed up by appropriate image analysis, is a very po
