När datorn blir kemistens bästa verktyg Datorbaserade verktyg blir mer och mer vanliga i de flesta verksamheter - och kemisk syntes är inget undantag. Genom att förutspå hur kemiska reaktioner sker redan innan de testas i labbet är det möjligt att spara tid, resurser och minska miljöpåverkan. Tekniken har därmed förändrat hur kemisk syntes planeras och genomförs. I många vitt skilda branscher spThe synthesis of small organic molecules in the pharmaceutical industry necessitates efficiency and selectivity. For obtaining selectivity in C(sp2)-H functionalization, thianthrenation has emerged as a promising method for furnishing electrophilic substrates, with thianthrene acting as a linchpin that facilitates selective functionalization through subsequent displacement reactions. This thesis u

Med anledning av den negativa bilden av SiS-hem som skildras i massmedier väcktes ett intresse för att undersöka ungdomarnas egna perspektiv närmare. Denna uppsats vill nyansera denna bild och ge en röst åt de ungdomar som vistats på SiS-hem. Syftet med uppsatsen är att undersöka hur ungdomar i videor på YouTube uttrycker sig om vistelse på SiS-hem. Uppsatsen bygger på en kvalitativ tematisk analy

Varje sekund blir du bombarderad av över 100 biljoner partiklar utan att märka någonting. Detta är för att partiklarna i fråga är neutriner, mycket mycket små partiklar, som nästan aldrig interagerar med någonting. De skapas i solen och färdas nästan helt obemärkta genom jorden. Men bara nästan obemärkta - om man har en tillräckligt stor detektor kan man se dem. Däremot kan det finnas en ny, hittiThe aim of this bachelor’s thesis is to investigate the potential for discovering sterile neutrinos or non-unitarity of the leptonic mixing matrix (LMM) at the European Spallation Source (ESS). Both sterile neutrinos and a non-unitary LMM have been suggested as origins of the LSND and MiniBooNE anomalies and in this work it is discussed to what extent these two models can be ruled out or confirmed

Video cameras are widely used for gait-based surveillance systems. However, they raise privacy concerns in sensitive environments such as private homes or restricted areas. As a result, radar-based methods are being explored as a privacy-preserving alternative. These methods are particularly promising with the emergence of high-resolution radar sensors capable of operating effectively in indoor co

Problem: Tidigare forskning har till stor del fokuserat på principerna som tillåter en organisation att nå en hög nivå av säkerhet, mindre fokus har lagts på hur personalen upplever och tillämpar dessa rekommendationer. Denna uppsats undersöker hur frontlinjepersonalen upplever att deras organisationer arbetar med säkerhet inom högriskfyllda miljöer då personalen är en central del i att organisati

This thesis investigates how human rights-based approaches (HRBAs) to disaster risk reduction mediate the relationship between international human rights law and local practice in the Philippines. It explores the processes of “vernacularization” and bottom-up influence. The former relates to adapting international human rights norms to local settings. The latter refers to local experiences and pra

In this paper, we investigate the prediction performance of several models across different forecasts horizons for the CNY/SEK and USD/SEK exchange rates, with a focus on incorporating macroeconomic inputs. Over the course of time, the Kalman filter method has been widely applied in the exchange rate forecasting literature, while the predictive ability of the Box-Jenkins Transfer Function (BJ) mod

Palm recognition is a biometric authentication method that uses the unique patterns of the palm for identification. The system requires users to position their hands accurately for biometric data to be captured. This thesis aimed to design an interface that supports accurate hand placement. The design process was conducted in three iterations, each including needs assessment, idea generation, prot

In a highly volatile and interconnected global environment, companies are increasingly exposed to disruptions such as pandemics, geopolitical conflicts, and natural disasters. These events can severely impact supply chains, especially for companies that rely heavily on external suppliers. The case company, a video surveillance technology provider, faces significant risks due to its limited bargain

This study is written for the purpose to analyze how automation in today’s modern flight deck is affecting pilots basic flying skills. It is focused on the pilot’s ability to control thrust. The main thesis transpires that pilots may had a better physical understanding around aerodynamics and speed control during basic flying training, operating aircraft with minimal or no automation (energy manag

Denna studie syftade till att undersöka ålders- och könsskillnader i moral, samt hur skillnader i moral påverkar bedömningar av brott. Brottsbeskattning användes som en praktisk applikation av moral. Moral Foundations Theory användes som ett teoretiskt ramverk. Det förväntas att äldre generationer skulle värdesätta bindande moralfundament, och att kvinnor skulle värdera individualiserande moralfunThis study aimed to investigate age and gender differences in morality, as well as, how differences in morality affects judgments of crime. Crime judgments were used as a practical application of morality. Moral Foundations Theory served as a theoretical framework for this study. It was hypothesised that older generations would value binding moral foundations, while women would value individualisi

This thesis investigates the economic effects of recreational cannabis legalization in Oregon, using Idaho as a control group through a Difference-in-Differences framework. It focuses on three key areas: unemployment, sectoral labor shifts in agriculture, and state tax revenue. The findings show a slight increase in unemployment and no meaningful shift into agricultural employment, suggesting that

The master’s thesis focuses on Gamified Green Information Systems (IS). It explores how gamified green IS influence employee behaviour and the motivational factors encouraging environmentally sustainable practices. For this, qualitative research was conducted, and data were collected through semi-structured interviews from seven employees. The data were analysed thematically to conclude to five th

This paper investigates whether political alignment between local mayors and departmental governors influences public investment decisions, specifically within the Colombian context. Using a regression discontinuity design based on close electoral outcomes, the study examines the allocation and efficiency of educational investments and related public expenditures across municipalities. Findings in

Abstract: This bachelor thesis explores the concept of just culture within aviation, with a specific focus on European airline captains’ knowledge, understanding, and perception of their reporting obligations. Grounded in the theoretical just culture framework of safety culture, developed by James Reason (1997), the study examines whether the principles of just culture - now nearly 30 years ol

Geologiska resurser är essentiella för den gröna omställningen, men även för Sveriges infrastruktur. Bland dessa resurser återfinns flera kritiska material, ämnen som EU-kommissionen identifierat som särskilt viktiga att unionen har tillgång till, så som magnesium, vanadin och fosfor. Det finns kända förekomster av kritiska material i Sverige och andra nordiska länder som kan komma att bidra till

The present study examined the relationship between identity leadership and employee well-being. Given the limited empirical evidence on the relationship between the specific identity leadership dimensions (prototypicality, advancement, entrepreneurship and impresarioship) and employee well-being, the current study aimed to explore these relationships. The study was conducted with a digital questi

Industrial policy regains interest in politics and academia to drive economic growth and solve challenges. However successful implementation remains challenging, and it lacks consensus on a common framework. Hence, firstly the study synthesises existing principles and frameworks into a comprehensive framework of principles for industrial policy for the 21st century. Secondly, it examines the align
