Background. Airborne SARS-CoV-2 plays a prominent role in COVID-19 transmission. Numerous studies have sampled air from patient rooms, but airborne spread to other hospital areas such as corridors is less investigated. Methods. Size-fractionated aerosol particles were collected weekly, with 12 hours of sampling time daily, in corridors at two infectious disease wards in southern Sweden between Mar
Title: Lessons from the financial crisis – the importance of communication in a world where business is king. Authors: Peter Houli and Robert Sarvik Mentor: Asta Cepaite Nilsson Problem statement: Currently, seemingly few studies have been conducted with focus on how organisations have used issues and crisis management during the financial crisis. Furthermore, issues and crisis management as field
A model for mate competition in moths sexually signalling with pheromones is presented. The model has four variables. N is the number of individuals of each sex per area unit. r is the length of the female odour plume as detected by a responding male. ε is a parameter increasing with male ability to discriminate between concentrations. r-ε becomes the competitive part of the female pheromone plume
Within strategic communication crisis communication is a relevant part of public relations in which practitioners developed guidelines for effective crisis communication (Seeger et al., 1998). Furthermore crisis communication is also relevant in political frames and political leaders need to know how to communicate during a crisis situation such as the Covid-19 pandemic. The Covid-19 pandemic is a
This paper deals with the disputable issue of the existence of Malthus’ Preventive Check in Chinese population. With the help of a newly established historical database (Demographic Database of Colonial Taiwan, DDCT), which currently including the individual level data regarding to the socio-demographic backgrounds of the registered population in fifteen townships in North and Western Taiwan, we t
Group B Streptococcus (GBS) is a leading cause of invasive bacterial infections in human newborns. A key GBS virulence factor is its capsular polysaccharide (CPS), displaying terminal sialic acid (Sia) residues which block deposition and activation of complement on the bacterial surface. We recently demonstrated that GBS Sia can bind human CD33-related Sia-recognizing immunoglobulin (Ig) superfami
This thesis concerns itself with the possibility that parental descriptions of psychological abuse by an intimate partner are viewed as less severe than claims of physical abuse by social workers involved in custody disputes. Swedish parents (N = 32) with experience of custody disputes were asked to write narratives describing incidents of psychological and physical abuse - abuse by their partner
In the Western world advice given by breastfeeding consultants about the use of one or two breasts at each feed has resulted in apparently arbitrary changes over time. This study compared 1-month-old breastfed infants' reactions to single- and two-breast feeds in terms of restlessness, crying, sleeping, and frequency of feeds, wet diapers, and loose stools. Eighty mothers were randomly assigned at
The Nordic Grid facility (NorduGrid [1]) came into operation during summer 2002 when the Scandinavian ATLAS HEP group started to use the Grid for the ATLAS Data Challenges (DC) and was thus the first Grid ever contributing to an ATLAS production. Since then, the Grid facility has been in continuous 24/7 operation. NorduGrid is being used by a growing set of active users from various scientific are
The assumption underlying this thesis is that both technological development and institutional and structural change are required to achieve a more sustainable building sector in China. Earlier literature has taken an approach based on the technological innovation system (TIS) to evaluate and understand the dynamics of technology development and change processes. However, fewer studies have examin
The complete amino acid sequence of the single polypeptide chain of human complex-forming glycoprotein heterogeneous in charge (protein HC) isolated from a single individual is reported with the supporting data. The primary structure was determined by automatic degradation of the intact chain and of fragments obtained by chemical and enzymatic degradations of the native or reduced and S-carboxymet
We have characterized 2 distinct mechanisms through which infectious agents may promote platelet adhesion and thrombus formation in flowing blood, thus contributing to the progression of disease. In one case, the process initiates when the integrin alpha(IIb)beta(3) mediates platelet arrest onto immobilized bacterial constituents that have bound plasma fibrinogen. If blood contains antibodies agai

This thesis investigates the role of trust in the context of decentralised finance (DeFi). Representing a new paradigm shift in finance, DeFi emerge from the technological developments that we have witnessing in the last decades, particularly decentralised ledger technologies (DLTs) of which Blockchain is perhaps the most popular. DeFi is changing the way that firms raise financial capital and a c
