Retinoic acid (RA) is an important morphogen that regulates many biological processes, including the development of the central nervous system (CNS). Its synthesis from vitamin A (retinol) occurs in two steps, with the second reaction - catalyzed by retinal dehydrogenases (RALDHs) - long considered to be crucial for tissue-specific RA production in the embryo. We have recently identified the Xenop

Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e., the Kronecker model and the Weichselberger model, and a cluster-based m

In ADB Safegate's airfield lighting product portfolio, two sizes of LED inset luminaires consist of similar internal components with different design. This project has investigated the possibilities to find generic design solutions for the internal components to fit both product sizes. By using modularized components the company will decrease the indirect costs of the product, for instance cos

Seminar date: 2nd June 2014 Purpose: The study's purpose is to investigate accountability in social enterprises. This is to answer the main thesis question of whether social enterprises and their accountability could provide the world with an alternative form of capitalism where humanitarian crises are better addressed. Methodology: The study applies a qualitative approach based on inductive

This thesis presents results from a study of socioeconomic and climate effects connected to a sugarcane ethanol expansion scenario in the Pontal do Paranapanema region, Sao Paulo state, Brazil. Sugarcane ethanol prodcution is expected to grow in the Sao Paulo state. Pontal do Paranapanema is the only region in the state where a large scale sugarcane expansion can take placré and this expansion wil

In recent years, Swedish municipalities have introduced programs that combine Swedish language education with vocational training. However, due to the novelty and lack of an established framework, data and research on their effectiveness in improving immigrant labour market performance is limited. This essay addresses this gap by estimating the causal effect of vocational training combined with Sw

Bakgrund: Meningsfulla aktiviteter är viktigt för att uppleva hälsa och välbefinnande. Idag finns en brist på meningsfulla aktiviteter för personer med demens som bor på särskilt boende för äldre. Personer med demens kan ha svårt att självständigt engagera sig i aktiviteter. Arbetsterapeuter har möjlighet att stötta människor att engagera sig i meningsfulla aktiviteter. Syfte: Att identifiera hur Background: Meaningful activities are important for experiencing health and well-being. Today there is a lack of meaningful occupations among people with dementia living in residential aged care facilities. People with dementia may have difficulty engaging in activities independently. Occupational therapists have the opportunity to support people to engage in meaningful activities. Aim: To identif

Framväxten av ”Big Data” har ställt EU:s lagstiftare inför nya utmaningar avseende skyddet för EU-medborgarnas grundläggande rätt till privatliv och personuppgifter. Detta då internet har medfört att enorma mängder av personuppgifter numera utan svårigheter kan överföras över landsgränser. Mot bakgrund av de utmaningar som följer av det gränslösa internet är ny EU-lagstiftning är på väg. Denna syfThe emergence of Big Data presents the EU legislator with new challenges of how to protect EU citizens’ fundamental right to privacy as the Internet allows for massive amounts of personal data to easily cross borders. To meet the new challenges created by the borderless Internet, new privacy legislation is on its way in order to provide EU citizens with an adequate and sufficient protection for th

The purpose of the thesis is to explore and understand the meaning, sources, and role of brands’ perceived innovativeness to talents due to the proposed importance of the attribute within the so-called war for talents as well as contemporary theoretical and practical discourse. In accordance with the relativistic and interpretivist stance taken, a qualitative methodology is adapted through the uti

According to estimates advanced by the United Nations, the annual SDG funding gap amounts to $2.5 trillion. The covid-19 pandemic further exacerbated the underlying issues as the global recession led to an unprecedented rise in public debts and economic distress triggered by defaults, capital flights and fiscal austerity. In light of these challenges, the Global Investors for Sustainable Developme

Title: “With Great Freedom Comes Great Responsibility” - A Qualitative Study of Managers’ and Their Respective Employees’ Experiences of Mandatory Remote Work and Relationships in this Work Setting Authors: Anna Rebeka Dinnyes & Siri McGarvey Supervisor: Monika Müller, Lund University, Sweden Examiner: Stefan Sveningsson, Lund University, Sweden Course: BUSN49, Degree Project in Master’s P

Environmental Education [EE] was created in the pursuit of providing specific targets to promote environmental, knowledge, attitudes, skills, participation and creating the societal shift. India was perhaps one of the first nations to have internalized EE in primary school curriculums, however, its application is still far from flawless. Teachers have often been observed as they take a central rol

A lattice model for fibril formation on the basis of general peptide interactions is presented. Fibrils are well-structured protein aggregates and a key phenomenon in many diseases, among them Alzheimer. We study the model’s equilibrium and kinetic properties using Wang-Landau sampling and a Metropolis Monte Carlo algorithm with cluster moves. The peptides are shown to form ordered fibrilar aggreg

The purpose of the study is to examine how companies are applying employer branding in social media and how these activities affect potential employees’ engagement. Engagement on social media has been analyzed according to the cognitive, emotional and behavioral dimensions using a mixed method content analysis.

The Baltic salmon has during the latter part of the 20th century been subjected to several threats. Most notable have been the high levels of contaminant release and a disease that causes early life mortality of the young. Ever since utilization of water power from the Swedish rivers began in the 1940ies, thus deminishing the natural breeding areas for the salmons, an extensive hatchery program ha
