Al-Ga-based alloys are promising carriers of renewable energy, which can provide hydrogen by hydrolysis in challenging working environments. Manipulating their performance by different process conditions and comprehending the mechanisms are important for achieving directional design synthesis of alloys and enhancing their practicality. This study presents a novel approach to optimizing the hydroge
A high-resolution integrated bio-chemostratigraphic framework is established for the upper Tremadocian to lower Floian (Lower Ordovician) succession of the North China Block, based on new conodont and carbon isotope (δ13Ccarb) data from the Jiguanshan and Wudingshan sections in Liaoning Province, northeastern China. Thirty conodont species of 19 genera were identified from the two sections. Based
A quantitative understanding of the hydro-environmental factors that influence the occurrence of agricultural drought events would enable more strategic climate change adaptation and drought management plans. Practical drought hazard mapping remains challenging due to possible exclusion of the most pertinent drought drivers, and to the use of inadequate predictive models that cannot describe droug
Considering the ever increasing financial damages of floods and the need to manage the surface water, the use of new and more sufficient methods seems to be necessary. Therefore, the present study aims to investigate capability of the Gamma, Beta, Chi-square, and Weibull probability distribution functions (PDFs) for flood hydrograph derivation. The present study was conducted in the Bar watershed,
PurposeThis study aims to investigate how stakeholder cocreation in 3D city mapping initiatives can extend the role of digital urban platforms beyond administrative efficiency toward the negotiation and enhancement of place attractiveness. Drawing on a participatory case study of Trollhättan, Sweden, the paper explores the needs, expectations and aspirations articulated by diverse stakeholder grou
IntroductionAnal squamous cell carcinoma (ASCC) is an HPV-related tumor primarily treated with concurrent chemoradiotherapy (CRT). Salvage surgery is reserved for patients with residual or recurrent disease following CRT, representing a highly selected, high-risk subgroup. Population-based data on outcomes and prognostic factors after salvage surgery are limited. This study aimed to assess overall
Evaluating the repellency of essential oils against Tetranychus urticae requires robust methodologies to detect time-dependent changes in their efficacy, due to differential efficacy, volatility, and sustained effectiveness. This study introduces the Pole-dance bioassay, a novel no-choice method optimized for high-throughput screening of time-dependent repellency, demonstrated through tests on twe
Recognizing the challenges in using botanicals as sustainable pest control agents due to compositional variation, this study addresses the limitations of traditional component-based approaches such as Hewlett and Plackett or Wadley’s models. Based on the assumption of noninteractivity among constituents, these models often fail to predict outcomes accurately due to dynamic intermolecular interacti
Along with the gradually accelerated urbanization process, simulating and predicting the future pattern of the city is of great importance to the prediction and prevention of some environmental, economic and urban issues. Previous studies have generally integrated traditional machine learning with cellular automaton (CA) models to simulate urban development. Nevertheless, difficulties still exist
OBJECTIVES: Early identification of treatment response in brain metastases remains clinically challenging. This study explores tensor-valued diffusion MRI (dMRI), specifically q-space trajectory imaging (QTI), as a novel source of early imaging biomarkers during stereotactic radiotherapy (SRT).METHODS: Twenty-six patients with brain metastases were enrolled; thirteen met quality and completeness c
En betydande del av Sveriges nationella ungdomspolitik syftar till att ge ungdomar större inflytande över samhällsutvecklingen. De målformuleringar som staten skapat genom bland annat regeringens liggande ungdomspolitiska proposition, har intresserat oss. Denna uppsats behandlar de normer som staten, genom olika dokument och skrifter, konstruerar för hur ungdomars politiska engagemang bör organise
Konflikten i Tjetjenien har blivit ett ihärdigt problem för såväl ryssar som tjetjener. Konflikten kan delas in i två faser, det första och det andra kriget. Våra studier av det empiriska materialet ledde till en misstanke om att det fanns luckor i den befintliga forskningen, i synnerhet gällande det andra kriget. Resultatet blev en teoriutvecklande studie om det andra Tjetjenienkrigets uppkomst o
Only 40% of the total CO2 emitted by human activities and natural sources remain in the atmosphere, since the rest is taken up by plants and oceans. In particular temperate and boreal forests are usually significant sinks of carbon, even if they are very susceptible ecosystems and they might turn into sources in consequence of the predicted temperature increase. That is one of the reasons why a ne
The purpose of this essay was to further develop the discussion around the street-level bureaucrats and the dilemmas that they meet in their work environment. The paper will try to accomplish this by putting the spotlight on the professional role, the organizational control of the street-level bureaucrat and the effect of society on the work environment. Something that also will be discussed is th
William G. Lycan undersöker i sin bok Philosophy of Language: a Contemporary Introduction möjligheten att förklara lingvistisk mening utifrån verifikationismen. Han lägger fram en mängd invändningar som tillsammans skall omkullkasta projektet. Då jag läst Lycans argument några gånger slås jag av det attraktiva med verifikationismens idé och av att jag vill syna kritiken lite närmre. Sammanfattning
Vi har i vårt uppsatsarbete valt att studera de fackligt engagerade arbetsplatsombudens vardag ur ett pedagogiskt perspektiv. Då vår frågeställning är av explorativ art ansåg vi att en kvalitativ ansats var att föredra. Vi har genomfört ett antal semistrukturerade intervjuer med dels utbildningsansvariga vid två regionalavdelningar samt ett antal arbetsplatsombud. Vid genomförandet av intervjuerna
There are reasons to believe that recent changes in the Swedish academic library environment create new images of identity. New information technology, changed educational methods and increasing numbers of students in higher education heavily influence the professional basis for librarians. The purpose of this essay is to examine and describe how the images of identity are conceived and expressed
Deliberative politics offers a new and exiting way of overcoming the problems that the western democracy of today is facing. A lot of research in the most recent years have had the goal to replace the representative democracy with a decision-making frame built on decentralization and deliberation. The goal for this essay is to create a framework for local decision-making, based on deliberativ norm
In this essay I discuss different normative foundations - theories of political ethics, for proposed cures to market failures. In addition to empirically match what cure fit what type of market failure, I posit the notion that the normative position of an economist, or policy maker, or of a group, concerned with these problems, delimits the options available for recommending, or analysing, what co
