Behavioral and electroencephalography (EEG) data were analyzed from 30 participants performing a demanding, attention-capturing task in which they had to detect an occasional decrement of luminance of small discs. Crucially, numerous white segments in the background were presented either in random orientations or configuring a contour shape of a square or a diamond. The participants' awareness of

Abstract Dark and light adaptation of pineal photoreceptors was studied in the isolated pineal organ of the rainbow trout, Salmo gairdneri. After intracellular recording, the photoreceptors were iontophoretically injected with Lucifer yellow CH or with horseradish peroxidase for morphological characterization. Pineal photoreceptor cells responded to light with a hyperpolarization whose amplitude w

Night,dawn,and dusk have abiotic features that differ from the day. Illumination,wind speeds,turbulence,and temperatures are lower while humidity may be higher at night. Nocturnal pollination occurred in 30% of angiosperm families across 68% of orders,97% of families with C3,two-thirds of fam-ilies with crassulacean acid metabolism (CAM),and 71% dicot families with C4 photosynthesis. Despite its w

Formation of Maillard products and the influencing factors, which are of crucial importance for both manufacturers and consumers, are still not fully understood. Thus in this study available lysine was used as a marker to monitor the extent of Maillard reactions in freeze-dried, spray-dried and drum-dried skim milk powders during 200 days of storage at highly controlled atmospheres. Storage variab

Research shows that a significant portion of the environmental impact from products is determined already in the design phase. Implementation of principles of Circular Economy (CE) in design practice has the potential to reduce waste and to encourage reuse of resources. Since designers are responsible for the design process, it is therefore relevant to investigate whether designers are properly eq

Railway traffic usually adheres to a timetable, but in Sweden, around two-thirds of the freight trains depart before they are scheduled, often by hours. Even though they occur in real operations, early departures have rarely been included in simulation studies and the effects on punctuality are not fully investigated. With a macroscopic simulation tool such as PROTON, large networks can be simulat

The strength of Sen’s concept of poverty lies in the fact that it goes beyond the traditional concepts of poverty and is able to grasp the complexity of poverty. At the same time, the strength of Sen’s concept of poverty is also its weakness. It is very abstract indeed. Income does not tell us much about poverty according to the capability deprivation approach since poverty is more than being shor

This research aims to question and uncover the social sustainability paradox arising from the inconsistent practice of third sector organisations’ values, for both their external stakeholders and internal workforce. To achieve so, this thesis discusses how the values are created, delivered and affected through the topology of the third sector, the organisational theories, sustainability theory and

Dagligen möts vi av bilder på barn som vårdnadshavare har publicerat på sociala medier. Ett exempel på detta är Calle Schulmans Instagramkonto där videoklipp på hans femåriga dotter läggs upp regelbundet. Frågan uppkommer om, och i vilken utsträckning, en vårdnadshavare får publicera personlig information om sitt barn. Vilka rättsliga medel och möjligheter finns att tillgå för barn om de känner siDaily we encounter pictures of children on social media, published by their custodians. One example of this is the Instagram account of Calle Schulman, where video sequences of his five-year-old daughter are frequently published. This raises the question whether custodians are allowed to publish personal information in this manner. What legal measures and opportunities are available to children wh

Precis som en viss färg kan beskrivas som en specifik blandning av grundfärgerna, så kan också en elektron också beskrivas som en slags blandning. Den här blandningen kan påverkas av ljus så att "mängden" av de olika komponenterna förändras. Det här är intressant att undersöka, för om vi vet vilka förutsättningar som gör att elektronen hamnar i en viss blandning, så kan man återskapa de

Användandet av digitala kommunikationskanaler blir allt vanligare. Traditionella arbetsplatser går mot mer moderna sådana då face-to-face kommunikation byts ut eller kompletteras av kommunikation i virtuella miljöer. Medarbetare kan idag genom diverse digitala verktyg arbeta ”när som helst, var som helst” och den virtuella miljön möjliggör för en rums- och tidsmässig frihet. Föreliggande uppsats äThe use of digital communication channels is getting more and more common. Traditional workplaces are moving towards of becoming more modern, since face-to-face communication is being replaced or supplemented with communication in virtual environments. By using various digital communication tools, co-workers can now work “whenever, wherever” and the virtual environment enables a spatial and tempor

The masters thesis The particular politics of the home - domestication and parental practices of digital games in everyday life aims at providing a closer look at how games played on phones, consoles or computers are regulated within the everyday of family life. Through semi-structured interviews with nine parents, the author creates understanding for how digital games are not only tied to the mor

The multidisciplinary Green Extraction approach has recently advanced by integrating the principles of Green Chemistry and the Circular Economy. In this framework, waste products are redefined as negative-cost raw materials for the recovery of high-value compounds with cross-sectoral applications, contributing to both economic and environmental sustainability. This study focuses on the valorizatio

Cyklometallering är en reaktion som används i alltifrån tillverkning av nya material till katalys av industriella kemiska processer, så att de sker snabbare och energisnålare. I denna reaktion reagerar en metall med en organisk molekyl (en ligand) och bildar en cykel och en ny metall-kolbindning. En typ av komplex som bildas genom cyklometallering är pincer-komplex, och dessa komplex kan bland annCyclometallation reactions and pincer complexes are both essential in organometallic synthesis and catalysis. The C-H bond activation is a key step in cyclometallation and metallacycles such aspincer complexes can thus be used to study this bond activation event. Much research has been conducted on the PCsp2P pincer complexes and their cyclopalladations, but not as much on their analogous sp3-hybr

När man färdas genom Sverige går det enkelt att notera att en stor del täcks av skog, närmre bestämt ungefär 70%. Flera av våra viktiga ekosystem med höga naturvärden finns bland denna grönska. Mycket skog innebär även många skogsägare som har olika behov. Därför behövs även olika typer av naturskydd för att hitta något som passar alla. Människan är del av ekosystemen, och vi skulle inte klara osThe European union and the Convention on biological diversity require 30% of all land to be protected by 2030, stressing the necessity for increased nature conservation. To meet the requirements different forms of protection are needed. Thus, nature conservation agreements (NCA) relevant for further exploration, as they are not used in as large of an extent as other nature conservation types. Thi

I Sverige idag uppskattas det att 16 procent konsumerar alkohol på ett sätt som bedöms som riskbruk. Detta är något som kan ge upphov till en rad olika konsekvenser, såsom sjukdomar, skador och missbruk. Vidare visar studier att fyra procent av individer mellan 16-24 år lider av någon form av spelproblem. Precis som med alkohol kan det vid konsumtion av spel utvecklas ett missbruk. Det är konstateIn Sweden today it is estimated that 16 percent consume alcohol in a way that is considered risky. This is something that can give rise to a range of consequences, such as illness, injury and addiction. Furthermore, studies show that 4 percent of individuals aged 16-24, suffer from some form of gambling problem. As with alcohol, the consumption of gambling can lead to addiction. It is recognized t

De utmaningar som dagens och kommande generationer står inför, till följd av klimatförändringarnas konsekvenser, har inga motsvarigheter i historien. Därför utmanas vårt tänkande och agerande från grunden. Som en följd av detta finns en rörelse som försöker påverka politiken och samhället i en mer hållbar riktning: klimataktivisterna. I oktober 2024 friades en klimataktivist av Stockholms tingsrätThe challenges faced by current and future generations as a result of the impacts of climate change are unprecedented. Therefore, our modes of thinking and acting are being fundamentally challenged. As a result, a new climate movement has emerged, calling on politicians to ensure sustainable policies and societies. In October 2024, a climate activist was acquitted by the Stockholm District Court o

Bakgrund: Personer med psykisk ohälsa upplever ofta svårigheter med sensorisk bearbetning, vilket kan påverka aktivitetsförmåga och livskvalitet negativt. Sensorisk modulering har nyligen introducerats som en positiv metod inom vuxenpsykiatrisk verksamhet i Sverige, men arbetsterapeuters kunskap och användning av metoden inom primärvården är ännu outforskad. Syfte: Att undersöka arbetsterapeutersBackground: Individuals with mental health problems often experience difficulties with sensory processing, which can negatively affect their ability to engage in activities and reduce quality of life. Sensory modulation has been introduced as a promising approach in adult psychiatric care in Sweden, but occupational therapists' knowledge and application of this method in primary health care re
