In this work, we employ density functional theory to assign vibrational signatures of [FeFe]-hydrogenase intermediates to molecular structures. For this purpose, we perform an exhaustive analysis of structures and harmonic vibrations of a series of CN and CO containing model clusters of the [FeFe]-hydrogenase enzyme active site considering also different charges, counterions, and solvents. The pur

Energy security is one of the main drivers of energy policies. Understanding energy security implications of long-term scenarios is crucial for informed policy making, especially with respect to transformations of energy systems required to stabilize climate change. This paper evaluates energy security under several global energy scenarios, modeled in the REMIND and WITCH integrated assessment mod

This article reflects on issues of globalisation and representation in contemporary visual culture.

The article begins from critical accounts addressing the crisis of politics and citizenship today, to study the civic potential that several media and social scholars view in informal practices that include the usage of new media and information and communication technologies. On one hand, new media and ICT are noted to empower individual users and groups, to provide spaces of voice and debate and

We present some results on the existence of bounded positive solutions to a class of nonlinear second order ordinary diferential equations by using the Schauder-Ekhonov fixed point theorem. An application to the existence of bounded positive solutions to certain quasilinear elliptic equations in two-dimensional exterior domains is also given.

Three novel tetracyclic terpenoids, of which two possess potent cytotoxic activities towards various mammalian cell lines, were isolated front extracts of the fermentation broth of the ascomycete Dasayscyphus niveus. The structures of the compounds, named dasyscyphins A-C, were determined with spectroscopic techniques. (c) 2005 Elsevier Ltd. All rights reserved.

Objective. In systemic sclerosis (SSc; scleroderma), T cells infiltrate organs undergoing fibrotic changes and may participate in dysregulated production of collagen by fibroblasts. The objective of this study was to functionally characterize T cells infiltrating skin lesions in early SSc and investigate their capacity to affect production of type I collagen and interstitial collagenase (matrix me

In addition to fermentable sugars, dilute-acid hydrolysates of lignocellulose contain compounds that inhibit fermenting microorganisms, such as Saccharomyces cerevisiae. Previous results show that phenolic compounds and furan aldehydes, and to some extent aliphatic acids, act as inhibitors during fermentation of dilute-acid hydrolysates of spruce. Treatment of lignocellulose hydrolysates with alka

Denna studie syftar till att studera ordaccenter hos barn i förskoleålder med skånsk dialekt och språkstörning. I studien undersöks huruvida barnen har problem med ordaccenterna och i vilken utsträckning. Barnens yttranden bedöms perceptuellt av två lyssnargrupper och akustiskt som spektrogram, där jag tittat på grundtonskurvan. Svar söks också kring huruvida vissa ord är svårare att bedöma eller

Allmänhetens förtroende är en grundläggande förutsättning för värdepappersmarknadens funktion. Investerarnas förtroende för allmänheten är tänkt att åstadkommas genom att minska företagens informationsövertag. Därför är de bolag som vänder sig till marknaden i syfte att anskaffa kapital skyldiga att tillhandahålla information i en erbjudandehandling, ett prospekt. Om informationen i ett sådant proThe public confidence is a fundamental prerequisite for the function of the securities market. The investors’ confidence is intended to be achieved by reducing the companies information advantage over the market. Hence, the companies which turn to the share market in order to raise capital are obliged to provide information in terms of a prospectus. Erroneous or insufficient information in such a

En central del av många internetföretags verksamhet är insamlingen, lagringen och användningen av personuppgifter som överlämnats till bolagen genom registrering. Med personuppgifter avses all information som kan hänföras till en specifik person och i takt med samhällets globalisering har denna information kommit att få ett betydande kommersiellt värde. Överföringen av personuppgifter från EU tillTo various internet companies the collection, storage and use of personal data that has been transmitted through registration is an essential part of the companies business. Personal data refers to all information relating to a specific person and as a consequence of society’s globalization this information has a considerable commercial value. The transfer of personal data from the EU to the US is

The large number of orphanages in Jinja, Uganda has promoted the widespread institutionalisation of children from poor families. Parents are left disempowered and have very few options but to sign over the rights of their children because NGOs in the region have largely prioritised orphanage care over other services. This paper critically analyses the failure of non-state actors in addressing the

This thesis analyses the impact of social networks on technology adoption among smallholder farmers in Ethiopia. The effects of four types of social networks on adoption of fertilizer and soil conservation practices were estimated using a sample of households from the Ethiopian Rural Household Surveys (ERHS). Trusted kinship links were found to have a small but positive effect on fertilizer adopti

This study aims to contribute towards the existing literature of volunteer tourism by evaluating the impacts that volunteering has on career progression. There exists a plethora of research on volunteer tourism, focusing on the various motivations to volunteer and the diverse positive and negative impacts that volunteering has on host communities. However, there is less research on the impact it h

Abstrakt Bakgrund: Distriktssköterskan har en nyckelroll i arbetet på vårdcentral och ett framstående ansvar och uppdrag. I ansvaret ingår att arbetat hälsofrämjande, personcentrerat och även att ha en ledande roll att utveckla omvårdnaden utifrån folkhälsoperspektiv. Den berörda problematiken som belyses av aktuell forskning och hälsomyndigheter är att ohälsosamma levnadsvanor medför stor sjukdo

This thesis investigates 1) How Chinese culture is represented and exported through the video game Genshin Impact, and 2) How the gaming experience of Genshin Impact influences Swedish players’ perception of China. Soft power has increased in importance in recent decades in China and video games are a new strategy. Five Swedish Genshin Impact players were interviewed about their experience and per

This thesis investigates the restitution of cultural artefacts looted during the colonial-era, through the comparison between two United Nations Educational, Scientific and Cultural Organization (UNESCO) Conventions and the newly proposed French guideline, Shared Heritage: Universality, Restitution and Circulation of Works of Art (SHURCWA). Through a qualitative case study employing Carol Bacchi’s

This thesis explores how entrepreneurs experience and regulate fluctuations in passion, and how these affect their decision-making in high-stakes contexts. While entrepreneurial passion has been widely recognised as a motivating force, little is known about how its intensity fluctuates over time and how such shifts influence strategic behaviour and decisions. Drawing on emotion regulation theory,
