Kärn- och elektrondynamik i atomer och molekyler är grunden för många fysiska processer och kemiska reaktioner. Ofta händer denna dynamik på tidsskalor som är så korta att de kallas ultrasnabba.För att studera ultrasnabba fenomen behövs tekniker som pump-prob-experiment med ultrasnabba ljuspulser. För att dessa experiment ska lyckas måste ljuspulsernas egenskaper noga studeras och styras för att d
Purpose: The purpose of this paper is to explore the current trends, implications and challenges of information systems (IS) related to omni-channel logistics. Design/methodology/approach: An exploratory survey study is conducted with 23 Swedish retail companies transforming to omni-channel logistics. The study investigates the retailers’ current situations regarding logistics IS as well as their
Internal positivity offers a computationally cheap certificate for external (inputoutput) positivity of a linear time-invariant system. However, the drawback with this certificate lies in its realization dependency. First, computing such a realization requires finding a polyhedral cone with a potentially high number of extremal generators that lifts the dimension of the state-space representation,
This book is about Erving Goffman’s frame analysis as it, on the one hand, was presented in his 1974 book Frame Analysis and, on the other, was actually conducted in a number of preceding substantial analyses of different aspects of social interaction such as face-work, impression management, fun in games, behavior in public places and stigmatization. There was, in other words, a frame analytic co
It is well known that during the suckling period pancreatic secretion is low. The aim of the study was to investigate the effects of dietary supplementation with pancreatic-like enzymes of microbial origin (PLEM) and SiO2, as an antibacterial factor, on the performance of piglets fed creep feed during weaning and thereafter. The experiment was performed on piglets from 30 litters. The piglets were
CONTEXT: The well-known side-effect profile of androgen-deprivation therapy (ADT) has significant quality-of-life (QoL) implications. Intermittent androgen deprivation (IAD) alternates androgen blockade with treatment cessation to allow hormonal recovery between treatment cycles, thus potentially improving tolerability and QoL. OBJECTIVE: To evaluate available evidence regarding the efficacy and t
Governance issues surrounding technologies are profound. This is best illustrated in the context of climate change that does not only exert severe, pervasive and multifaceted impacts on the environment and on the everyday lives of people around the world, but also further aggravates the tension between law, technology and the public in a broader societal context. As a response to feckless global a
A hot-carrier solar cell aims to generate power from energetic, photoexcited, charge carriers, so called hot carriers, in order to reach higher conversion efficiencies than current solar cell technology.Creating a hot-carrier solar cell has proven challenging for two main reasons: hot carriers lose their energy very quickly, and they need to be extracted over distances of a few hundrednanometers v
The Arctic has undergone extreme changes during the last decades and is warming over twice the global average. There has been increasing interest in understanding how warming and changes in snow and rainfall will affect high-latitude ecosystems. Although observational studies highlight the importance of cold-season carbon fluxes on the annual carbon balance, models, in general, cannot realisticallThe Arctic has undergone extreme changes during the last decades and is warming over twice the global average.

Title: A framework for how logistics service providers should handle returns as a warehouse operation for pure e-commerce companies Authors: Louise Meurling and Matilda Sturesson Supervisor: Joakim Kembro, Division of Engineering Logistics at LTH Problem description: Managing the reverse logistics process in a warehouse is a central part of the activities for companies operating in e-commerce.
This paper discusses the relationship between the Mouridiyya order and the Jamatou Ibadou Rahmane Association- two significant and quite different Muslim organizations in Senegal. This case is illuminated in order to help explain why supposedly opposed groups entertain peaceful relationships. The data analyzed derives from nine interviews conducted between January 2014 and March 2014, in Dakar, Se
Problem background: In the beginning of 2011 the working capital levels rose drastically for companies operating in the polymer industry, as a result of macroeconomic factors and changes of supply market conditions. Suppliers were allocating capacity and uncertainty spread among buyers, which resulted in that large volumes were purchased in order to secure supply. Moreover, the suppliers were dict
Ett antal flodskärningar undersöktes längs Logatafloden och dess omkringliggande områden för att ge en ökad förståelse om de senaste istiderna för denna del av världen. De påträffade sedimenten vittnade om en marin miljö efter en isframstöt och därefter en landhöjning som ledde till dagens flod- och tundralandskap. Det finns många teorier angående hur utbredd inlandsisen var över arktiska SibirieA number of sites were investigated in river sections along the Logata River on the Taymyr Peninsula, Russia, and its adjacent areas to shed more light on the glaciation history over the last glacial cycles. The sediments exposed at the investigated sites are correlated and put into a local stratigraphic scheme divided into five main units. Unit 1 is positioned lowest in the stratigraphy and con
Background: FTV Capital is a private equity company specializing in growth equity. Even though the company has been very successful, the private equity industry is highly competitive and more and more companies are turning their strategy towards growth equity. To stand out and keep the competitive advantage, having a strong brand and communicating efficiently is particularly important for a privat
Denna uppsats syftar till att belysa hur social acceleration kan förstås påverka lagstiftningsprocessen och lagstiftningsprodukten. Med utgångspunkt i 36 § AvtL, undersöks hur social acceleration speglas i lagstiftningsarbetet. Detta görs särskilt i förhållande till den problembild lagstiftaren beskriver, lagens syfte och slutligen hur detta tar sig uttryck i dess utformning. För att uppnå detta sThis paper aims to shed light on the impact of social acceleration on the legislative process and the legislative product. § 36 of the Swedish Contracts Act (henceforth referred to as the Contracts Act) forms the basis for an examination of how social acceleration is reflected in the legislative process. This is in relation to the problem described by the legislator, the purpose of the law and fin
The efficiency in an internal combustion engine ranges from 25% to 45%. About 50% - 85% of the overall energy losses in a combustion engine is heat which is either cooled away by the vehicle's radiator or blown out with the exhaust gases. The heat has to be cooled off by the vehicle's cooler and this energy is never put into use again and is therefore called 'waste heat'. Even if a
The following thesis engages critically with the incorporation of a parallel digital platform alongside REKO Åland, a self-organized alternative food network operating primarily through Facebook, and how such addition of digital infrastructure reconfigures the network’s organizational boundaries. REKO’s grassroot coordination is constituted through direct producer–consumer exchange of local food,
Female researchers remain visibly under-represented among deep-tech founders in Germany. Although women are present in Science, technology, engineering, and mathematics (STEM) education and early academic research, the founder gap is larger than the pipeline alone would predict, signalling leakage at later, commercialisation-oriented stages of the academic career. This study examines how female re
