In this paper, we discuss the exclusive photoproduction of ground and excited states of ψ(1S,2S) and ϒ(1S,2S) in ultraperipheral collisions (UPCs). Using the potential model in order to obtain the vector meson wave function, we find a good agreement of our calculations with data from the LHC and HERA colliders for J/ψ(1S,2S) and ϒ(1S) in γp collisions. We extend the calculations to the nuclear tar
Klimatrelaterad migration är en betydande och oundviklig konsekvens av klimatförändringarna, och något som kommer att ske alltmer i takt med att klimatrelaterade händelser och katastrofer sker med ökad frekvens och magnitud. Olika stater har bidragit olika mycket till de antropogena klimatförändringarna, med vilka riskerna är ojämnt fördelade mellan stater och områden världen över. Vidare är vissaMigration is a considerable, as well as an inevitable, consequence of climate change. As the frequency and dimension of climate change events increase, climate induced migration will increase as well. Not all states have contributed equally to the anthropogenic climate change, nor do they face the same risks connected with it. Furthermore, climate change does not affect everyone within a state in
Vi lever i en tid av snabb teknisk utveckling. På bara några decennier har den sociala miljön förändrats drastiskt. Vi har gått från en värld där social interaktion bestod i direkt kontakt mellan två individer till en värld där en stor del av det sociala utbytet inte sker ansikte mot ansikte utan skärm mot skärm. Denna nya verklighet har medfört en intensifierad konflikt mellan två av våra mest beWe are living in a world of rapid progress. In just a few decades our social environment has developed drastically. We have progressed from a world where social interaction consisted in direct contact between individuals to a world where a significant part of the social exchange no longer happens face to face but screen to screen. This new reality has resulted in an intense conflict between two of
Uppsatsen syftar till att utreda reklamationspliktens innehåll vid felaktig och vårdslös kommersiell rådgivning, t.ex. rådgivning från advokater, revisorer eller skattejurister till kommersiella uppdragsgivare. Uppsatsen utreder när reklamationsfristen startar, hur lång reklamationsfristen är och vilken rättsverkan som följer av en sen eller försummad reklamation vid felaktig och vårdslös kommersiThe purpose of this essay is to investigate the content of the legal principles regarding notice of claim related to wrongful and negligent commercial advice, for example advice from lawyers, accountants or tax lawyers to commercial clients. The essay investigates the starting point for the notice period, the length of the notice period and the legal effect of a late or neglected notice of claim r
TOYS & MEMORIES What makes some toys great? This was the question that started this entire project. When remembering toys from ones childhood there are always some toys that are more commonly referenced. Were these toys “the best toys” and more importantly: what traits made them better, and can they be replicated? A toy is something created with the main purpose of being a catalyst for ones i
Nanoscience is an emerging field of technology where the bottom-up fabrication techniques are utilized instead of the traditional top-down approaches for enhancing the performance of di erent optoelectronic devices. One such material is a semicon- ductor nanowire (NW) which holds immense potential in nanophotonic applications, such as solar cells, LEDs, lasers, sensors and photodetectors. In parti
Personer med HIV utsätts för stigmatisering och diskriminering inom hälso- och sjukvård. Syftet med denna litteraturstudie var att belysa sjuksköterskors attityder vid bemötande av personer med HIV både från sjuksköterskors samt HIV-positiva personens perspektiv. tio vetenskapliga artiklar som behandlade problemområdet lästes och analyserades, varav fem berörde sjuksköterskors perspektiv och fem p
Bakgrund: tidigare studier visar att kvinnor upplever att föräldragrupper inte förbereder dem för amning. Det är viktigt att studera hur kvinnor upplever amningsinformation under graviditeten då detta kan öka amningsfrekvensen. Syfte: Att undersöka kvinnors upplevelse av amningsinformation under graviditeten. Metod: en kvalitativ studie gjordes och elva kvinnor intervjuades. Kvalitativ innehålls
I och med införandet av den tillfälliga lagen har en asylsökandes skyddsstatus fått ökad betydelse. Exempelvis har flyktingar rätt till familjeåterförening medan alternativt skyddsbehövande som regel inte har det. Sverige har bland annat kritiserats av UNHCR för att få personer, vid en internationell jämförelse, beviljas flyktingstatus i landet. Detta arbete undersöker domar från migrationsdomstoAsylum seekers’ protection status has become more important since the implementation of the temporary migration law in Sweden, inter alia as people with refugee status have a right to family reunification while people with subsidiary protection do not. Sweden has several times been criticised, including by the UNHCR, as few people, in an international comparison, are granted refugee status in the
Functionalization of a TB analogue through a six step synthesis has been performed, collecting valuable material for further synthesis towards a heptakis TB analogue and characterization of intermediates. Previous work in the Wärnmark group has produced this heptakis TB analogue and this project focused on following the worked out procedure and improving it where possible. The synthesis started fr
Increasing water demand and water security risks are global concerns for societal prosperity and business continuity as clean water is a critical input in several industrial processes. Understanding water risks is a complex field and few studies exists on the effects of water supply disruptions on industries. Economic impact assessment of water shortages is therefore important for insurance and ri
A high informality incidence, measured as the share of informal employment out of total employment, is a common characteristic of most developing countries’ economies. In Mexico, where informal employment accounts for the majority of labour activity, this is argued to be a consequence of its unique social policy. The introduction of the social protection program for health in 2002, Seguro Popular,
We propose a distributed optimization algorithm for mixed L_1/L_2-norm optimization based on accelerated gradient methods using dual decomposition. The algorithm achieves convergence rate O(1/k^2), where k is the iteration number, which significantly improves the convergence rates of existing duality-based distributed optimization algorithms that achieve O(1/k). The performance of the developed al
En person som stammar får ofta lära sig att tala långsamt, för att på så sätt minska sin stamning. Betyder det att hög talhastighet alltid försvårar stamningen? Och ökar i så fall stamningsgraden linjärt med talhastigheten?
Discussion concerning the concept of cultural identity in connection with education and media pedagogy
Objective: To review research articles in psychiatry and psychology involving Latin American populations and/or produced by Latin American scholars to investigate the differential diagnosis between spiritual/anomalous experiences and mental disorders in order to contribute to the validity of the International Classification of Diseases towards its 11(th) edition in this area. Method: We searched e
Studies from the public health and epidemiologic fields consider self-assessment of health as a solid measure of general health due to its predictive ability in relation to mortality. Empirical evidence in this direction have justified the generalized use of this measure in health surveys as well as its application to the general population. However, it is important to evaluate whether these findi
