When ultrashort pulses propagate through common optical elements, such as gratings and thick lenses, they inevitably acquire spatiotemporal couplings (STCs), which are nonseparable chromatic aberrations. This phenomenon fundamentally stems from the broad spectral bandwidth inherent to ultrashort pulses. STCs can significantly reduce peak intensity, enlarge the focal spot, and thus limit the optima
Denna studie granskar det urbana hållbarhetsarbetet i Köpenhamn, nämligen deras ”Smart city”- strategi, med fokus på ett specifikt spårningsprojekt som staden startat. Några aspekter som tas upp är integritet, medborgardeltagande och transparens. Som en konsekvens av en ökande urbanisering står städer världen över inför flera urbana utmaningar som kräver att de förändrar hur de planerar och arbeCities around the world are facing a multitude of urban challenges that demand that they change the way they plan and think about their city, with one of the ways of approaching sustainability being the Smart city. A core feature of the Smart city is the idea of collecting large quantities of data on the city, big data, which is then used in various city solutions. In the wake of this, several que
Ju mer effektiv MIFO-ärenden hanteras, desto bättre är tillsynen av förorenade områden vid pågående verksamheter Miljöfarliga verksamheter i drift kan ge upphov till förekomst av föroreningar i mark, vilket vid förhöga halter kan orsaka skadliga effekter på människors hälsa och miljön. I Sverige, har inventering av pågående verksamheter enligt MIFO metodiken genomförts för att förbättra hanteringThe management of contaminated sites is an important issue since exposure to soils with high concentrations of pollutants causes serious damage to human health and the environment. To cope with this issue, Swedish local environmental protection authorities started an inventory of the operational activities that are potential point sources of pollution. MIFO phase 1 methodology is used by the local

To improve functional properties, 2 different types of egg albumen powder (high gel instant and ordinary) were hydrolyzed with four proteases (FPC, NPU, BAP and PSP) using different protease concentration (low, medium and high) at 50C for 1 h and subsequently polymerized by transglutaminase at 40C for 24 h. The enzymatic modified egg albumen was analyzed for foaming properties: foamability as %ove
This thesis discusses a rather contentious issue of how copyright law possesses musical works nowadays. It is essentially argued in the thesis that current copyright law appears to be too restrictive, leaving not enough space for creativity in the musical world. In this regard, the issue related to musical works are mainly analysed through the prism of the idea-expression dichotomy. One of the gen
Jordbruk är avgörande för människans överlevnad och idag står det inför många problem relaterade till både klimatförändringar och en ökande befolkning. Medan ökande totalskördar under 1900-talet har skapat förutsättningar både för global ekonomisk tillväxt och för befolkningstillväxt, har de jordbruksmetoder som används ofta fört med sig negativa konsekvenser både för ekosystem och människor. JordAgriculture is essential for human survival and today it faces many problems related to both climate change and an increasing population. While increased total yields during the 20th century have created the conditions for both global economic and population growth, the agricultural practices utilized have often had detrimental consequences both for ecosystems and people. The agricultural sector i
The essay's investigation of postmodern storytelling and transformative screenwriting, in relation to how Robert McKee's Story is reflected in Charlie Kaufman's Adaptation – in text and subtext, form and content – shows that the film's form is that of the classical archplot. It is only Adaptation's content, reflecting the dream of an art film/antiplot that is critical – while t
Barnets bästa ska vara avgörande vid alla beslut som rör vårdnad, boende och umgänge. Vid bedömningen av barnets bästa skall hänsyn tas till barnets vilja med beaktande av barnets ålder och mognad. Det framgår tydligt av såväl FN:s konvention om barnets rättigheter (barnkonventionen) och av svensk lag. Lagtexten ger endast vägledande riktlinjer när det gäller bedömningen av barnets bästa för att uThe best interest of the child should always be decisive in all decisions concerning custody, accommodation, and relations of the child. When assessing what is best for the child the will of the child should be considered. Moreover, the will of the child should be evaluated according to two affecting factors; age and maturity. This clearly appears in the Convention on the Rights of the Child prese
Heart rate variability as an indicator of increased morbidity has been established in previous studies. It is defined by different frequency bands, corresponding to different biological mechanisms. This thesis aims to study heart rate variability indices in the time-frequency domain through extraction from the UK Biobank dataset. Time-frequency indices for different time intervals during exercis
Offentliga upphandlingar i Sverige omsätter uppskattningsvis 634 miljarder kronor per år och har således en stor påverkan på samhällsekonomin. Genom lagen (2016:1145) om offentlig upphandling (LOU) infördes det för första gången en skyldighet för den upphandlande myndigheten att överväga och besluta om kontrakt ska tilldelas i separata delar eller genom ett samlat kontrakt. Beslutet är inte överprThe turnover of public procurement is approximately 634 billion SEK a year and thus has a large impact on the national economy. The Swedish enactment of public procurement (lagen (2016:1145) om offentlig upphandling, LOU) introduced a new obligation for the contracting authorities. They have now a duty to consider the appropriateness of dividing contracts into lots. According to LOU the contractin
Människans fysiska behov av sömn är uppenbara, men vilken funktion fyller egentligen sömnen och drömmarna för psyket? Det är något av ett mysterium trots att både sömn och drömmar är föremål för mycket debatt, teorier och studier. I den här studien undersöks kopplingen mellan sömn, mardrömmar och försvarsstrukturer. Kan en kort sovstund dagtid påverka våra försvarsstrategier, gör den vårt psyke meThe purpose of this study was to investigate whether sleep leads to more flexible use of defense mechanisms, and linkages between defense structure, anxiety and nightmares, the two conditions, sleep and rest. 69 participants were recruited for the study and they were divided into a sleep group (n = 48) who received a period of sleep during the daytime while the other partcipants (n = 16) rested du
