Like their diurnal relatives, Megalopta genalis use visual information to control flight. Unlike their diurnal relatives, however, they do this at extremely low light intensities. Although Megalopta has developed optical specializations to increase visual sensitivity, theoretical studies suggest that this enhanced sensitivity does not enable them to capture enough light to use visual information t
Background: Inflammation acting in synergy with brain ischemia aggravates perinatal ischemic brain damage. The sensitizing effect of pro-inflammatory exposure prior to hypoxia is dependent on signaling by TNF-alpha through TNF receptor (TNFR) 1. Adrenoceptor (AR) activation is known to modulate the immune response and synaptic transmission. The possible protective effect of (alpha) over tilde and
Standard-setting is undoubtedly beneficial to society. Its foremost advantage is that it ensures interoperability between products and thereby increases consumer welfare. Standardization covers a wide range of activities, but for the purpose of this thesis it can be defined as activities that set technical specifications that seek to provide a common design for a product or process. Standards thus
I dagens samhälle kämpar företag för att höras och synas i det överflöd av information som finns tillgänglig. Ett särskiljande kännetecken har därmed blivit ett mycket viktigt kommunikationsmedel för företag. I detta kännetecken ligger ofta ett betydande värde i form av goodwill och image och attityd hos förbrukarna. Inte sällan är det hela koncept som förmedlas i ett komplicerat byggande av relat
By using the method of framing analysis this bachelor’s thesis investigates how the debate of Scottish independence is framed by leaders representing the four largest political parties in Scotland. The material consists of speeches the politicians have held in the year of 2013, all speeches addressing the 2014 referendum and the issue of Scottish independence. By deconstructing the arguments commu
Neonicotinoids, e.g. clothiandin, imidacloprid and thiamethoxam, is the most used class of insecticides worldwide. However, lately, this group of insecticides has been subject to controversy. Due to the systemic traits of neonicotinoids, the active compound is translocated throughout the whole plant, which provides effective and long-lasting protection against herbivorous pests. On the other hand,
This essay analyses conceptual metaphors in the Beatles’ song lyrics and observes how Lennon and McCartney’s use of metaphorical concepts evolved in the 1960’s. The study has an empirical and qualitative approach with quantitative elements, and employs the framework of Conceptual Metaphor Theory (CMT). Three specific RQs are studied in this thesis: (a) how the metaphors in Lennon and McCartney’s l
This thesis explores the positioning of internal crisis communication in relation to external communication, specifically within the context of governmental crisis response. Guided by the case of the Lebanon crisis in 2024, this study investigates how crisis experts from a European Ministry of Foreign Affairs interpret internal communication across the three phases of crises, drawing on the Rhetor
Using data from 159 participants (Mage = 27.11 years; SD = 6.47; 55% men), we investigate the relationships between personality traits, acculturation towards heritage and mainstream culture, and sociocultural adaptation among non-Western immigrants in Sweden. A series of regression analyses have shown conscientiousness and agreeableness significantly related to heritage culture identification, whi
Coiled-coil domains of intermediate filaments (IF) and prokaryotic IF-like proteins enable oligomerisation and filamentation, and no additional function is ascribed to these coiled-coil domains. However, an IF-like protein from Streptomyces reticuli was reported to display cellulose affinity. We demonstrate that cellulose affinity is an intrinsic property of the IF-like proteins FilP and Scy and t
BACKGROUND: Recent studies have found that particulate matter (PM) attached radioactivity was associated with certain adverse health effects including increased blood pressure and lung dysfunction. However, there has been no investigation on the direct effect of PM radioactivity on mortality.METHODS: Exposures to ambient PM gamma activities were determined using U.S. EPA RadNet data. Data on daily
Urban wildness refers to natural ecosystems within built-up areas that are subject to minimal human interference. It can provide huge social benefits and contribute to more liveable towns and cities. It can provide places for active recreation, aesthetic enjoyment, and interactions with nature that are otherwise unavailable in urban environments. It can improve health and wellbeing by encouraging
The study of clines, or geographical variations of a given trait, can help understand how the interactions of genetics and local environments determine phenotypic diversity. The marine snail Littorina saxatilis (Olivi, 1792) exhibits a gradual change in the relative frequencies of shell color morphs across populations in the estuary system of the Rias Baixas (Galicia, NW Iberian Peninsula). A cons
Plastic’s unique properties are vital for a sustainable future, but its excessive global use signifies consumer society’s wastefulness, often found in short-lived products. Plastic development has overlooked recycling needs, resulting in low material recycling due to a wide array of plastic types with varying additives, leading to recycling challenges. Research focused on thermoplastics aims to re
Disease progression is slower in HIV-2, as compared with HIV-1 infection, in accordance with low or undetectable plasma viremia at viral setpoint. However, it is unclear why most HIV-2 infected individuals are still at risk of developing AIDS. To explore if specific host responses are linked to HIV disease severity, we have compared blood gene expression profiles between HIV seronegative and HIV-1
