Långdistansflyttande fåglar uppvisar ett flertal gemensamma egenskaper som ger dem goda förutsättningar att regelbundet förflytta sig över kontinentala avstånd. De har exempelvis en effektiv flygmotor som gör att de kan hålla sig flygande, och en god förmåga att både lägga på sig, och bränna fett som flygbränsle. Fåglar uppvisar i regel också goda orienterings- och navigationsegenskaper, vilket ärMany birds are predisposed to annually undertake movements over large temporal and spatial scales. They have an efficient flight machinery, demonstrate impressive capacities in storing and burning fuel, and they exhibit necessary orientation and navigational skills. Avian migrants are still limited in the amount of time and energy they can allocate towards their movements and need to balance migra

The measurement of potential enzymatic activities has been proposed as an efficient method to infer nutrient limitations for microorganisms in environmental samples. To validate this use, confirmation with direct methods of microbial growth responses to resource additions are required. We experimentally manipulated nutrient-poor soils from the afromontane subtropics with relatively low (grassland

Objective To evaluate the psychometric properties of the Fatigue Severity Scale (FSS), the Fatigue Impact Scale (FIS), and the Multidimensional Fatigue Inventory (MFI-20) in persons with late effects of polio (LEoP). More specifically, we explored the data completeness, scaling assumptions, targeting, reliability, and convergent validity. Methods A postal survey including FSS, FIS, and MFI-20 was

The very young Wabar craters formed by impact of an iron meteorite and are known to the scientific community since 1933. We describe field observations made during a visit to the Wabar impact site, provide analytical data on the material collected, and combine these data with poorly known information discovered during the recovery of the largest meteorites. During our visit in March 2008, only two

In the study of the distant human past, certain events and periods have come to represent decisive passages from one human state to another. From a global perspective, the characteristic feature of the last ten t

The aim of this thesis is to critically examine how ethical principles are conceptualized and applied in educational contexts, focusing on the intersection of early childhood education and education for sustainable development. Its contribution to educational research in general, and to philosophy of education in particular, is to; first, discuss the presumed relation between ethical principles an

Popular Abstract in Swedish Barn ar ofta bärare av luftvägsbakterien pneumokocker i de övre luftvägarna och det är barnen som anses vara den största reservoaren för bakterien i vårt samhälle. Vanliga pneumokockinfektioner såsom öron-, bihåle- eller lunginflammation föregås av att man bär på bakterien. De flesta barn som är bärare blir dock inte sjuka. Vuxna är mer sällan bärare av bakterien. PneuThe paediatric nasopharyngeal flora is regarded as the largest reservoir for Streptococcus pneumoniae, and the carrier state is always antecedent to infection and a prerequisite for dispersion of these bacteria. Pneumococci are the predominant aetiology of bacterial respiratory tract infections and a major cause of morbidity and mortality, in the most severe cases due to invasive pneumococcal dise

Objective To assess the accuracy and reproducibility of ultrasound 'pattern recognition' for the diagnosis of borderline ovarian tumors by asking experienced ultrasound operators to evaluate representative images of different types of adnexal tumor. Methods Digitally stored static two-dimensional B-mode images of representative cases of benign, borderline and invasive malignant ovarian tumors were

Abstract This research focuses on the lives of three Icelandic women born early in the 20th century. The aim of this study was to try to understand how these women viewed their life and how they experienced the changes that Icelandic society has undergone in the 20th century. The women are viewed as active agents that shaped their own lives but also had to live within material and social constrai

Trots att en domstolsförhandling är av stor vikt för många barn som har utsatts för sexuella övergrepp visar undersökningar att endast tio procent av anmälningarna om sexualbrott mot barn leder till åtal. Syftet med denna uppsats är dels att presentera de åtgärder som företas i förhållande till målsäganden under förundersökningen, dels att fastställa om det finns faktorer som är avgörande för huruA trial is very important for children who have been sexually abused, however studies show that only ten percent of police reports lead to a prosecution. The purpose of this essay is to discuss the current procedure for investigating reports of sexual abuses against children. The paper will determine whether there are factors that are relevant if a case is prosecuted or not and thus can contribute

[translated title] Supervisor: Torbjörn Hjort The main purpose of this study was to examine the social interaction on blogs, written by someone that unexpected lost a beloved one. The main focus was therefore on how both the blogger and

Svensk sammanfattning I och med inträdandet av en avkriminalisering beträffande homosexualiteten i juli 1944 kom homosexuella handlingar att inte längre ses som något brottsligt. Kampen mot jämställdhet slutade inte där, det skulle dröja fram till 1979 innan homosexualiteten ströks ur Socialstyrelsens listor över sjukdomsbegrepp. Idag har homosexuella bland annat rätt att ingå äktenskap och adoptEngelsk sammanfattning Due to the entry into force for a decriminalization regarding homosexuality in July 1944, homosexual activities were not considered as something criminal anymore. The struggle towards a more equal society did not end there. It took until 1979 before homosexuality was removed from the National Board of Health and Welfare (Socialstyrelsens) register of illnesses. Today, homos

Den statligt tillsatta Vanvårdsutredningen konstaterade år 2010 att det under en stor del av 1900-talet förekommit många fall av allvarliga försummelser och övergrepp vid institutioner och familjehem inom den sociala barnavården. Med anledning av vad hade som presenterats tillsatte regeringen därefter Upprättelseutredningen med uppdrag att närmare utreda möjligheterna till upprättelse för de barn In 2010, a commission, appointed by the Swedish government, found that serious neglect and abuse had been occurring within the public childcare system during the 20th century. As a result of these findings, a second commission was mandated to inquire the possibilities for restitution for all children who had experienced neglect or abuse between 1920 and 1980. The commission suggested that an econo

Kvarts är ett av de vanligaste mineralen i jordskorpan, både i sediment och i bergarter. Halten kvarts i sediment är intressant vid bedömning av bl.a. mognadsgraden. Ett sediments mognadsgrad kan användas vid tolkning av dess historia, vilket är till nytta vid t.ex. rekonstruktion av paleomiljöer. Geologiska institutionen vid Lunds universitet, har efterfrågat metoder för bedömning av kvartshaltenQuartz is one of the most common minerals on Earth and is found in both lose sediment, sedimentary rock and bedrock. The maturity grade of sediments can be determined by the amount of quartz it contains. This is used when interpreting the sediments’ geological history and reconstructing paleoenvironments. The purpose of this thesis is to analyze and develop methods for determining the quartz conte

Popular Abstract in Swedish Cancer är ett samlingsnamn för en grupp av sjukdomar som karakteriseras av att cellerna delar sig okontrollerat, till skillnad mot kroppens friska celler. Det leder till att en tumör kan bildas och cellerna kan därifrån sprida sig till andra delar av kroppen och ge upphov till dottertumörer, även kallade metastaser. I Sverige uppskattar man att cirka var tredje person k

Background: Attention deficit/hyperactivity disorder (AD/HD) and autism spectrum disorders (ASDs) are early-onset, but often life-time impairing, neurodevelopmental disorders. They are highly overlapping and seem to carry considerable risks of negative outcomes, psychiatrically and psychosocially. Childhood hyperactivity is a known risk factor for early-onset conduct disorder (CD), but details con

Multi-electrode geoelectrical imaging has become very popular and is used for many different purposes. For some of these, the inclusion of IP data would be desirable as it would allow the interpreter to distinguish between, e.g. sand formations with saltwater infiltration and clay formations or help delineate landfills. However, present-day IP measuring techniques require the use of nonpolarisable

Popular Abstract in Swedish En industrirobot är en flexibel programmerbar maskin som bör användas för sådant arbete som inte lämpar sig för människan att utföra. Olika tekniska begränsningar i dagens styrsystem begränsar dock robotars tillämpbarhet. Avhandlingen föreslår ett nytt sätt att bygga upp robotstyrsystem så att roboten på bästa sätt skall kunna tjäna människan.Industrial robots play a key role in manufacturing systems. Robots are distinguished from other types of machinery mainly on the basis of their programmability and ability to be adaptable to different tasks. The use of computer control to achieve desired flexibility implies that software issues for embedded control systems are central for the applicability and utilization of the equipment. The str
