We prove that unary Sherali-Adams requires proofs of size nΩ(d) to rule out the existence of an nΘ(1)-clique in Erdős-Rényi random graphs whose maximum clique is of size d ≤ 2 log n. This lower bound is tight up to the multiplicative constant in the exponent. We obtain this result by introducing a technique inspired by pseudo-calibration which may be of independent interest. The technique involves

Transformation projects still tend to focus on buildings that once had life. This thesis aims to work with those that were never brought to it. In today’s world, there are an increasing amount of projects that garner a lot of attention and investment quite quickly. Some of these are taken through to the design stage and into development, only for them to suddenly not be viable. Development quickl
MreB forms a cytoskeleton in many rod-shaped bacteria which is involved in cell shape determination and chromosome segregation. PCR-based and Southern analysis of various actinomycetes, supported by analysis of genome sequences, revealed mreB homologues only in genera that form an aerial mycelium and sporulate. We analysed MreB in one such organism, Streptomyces coelicolor. Ectopic overexpression
In cities, land-use decisions made during planning processes determine the availability of ecosystem services fundamental to the wellbeing of urban population. Hence, the inclusion of ecosystem services in planning is essential to promote sustainable urban development. This article investigates to what extent ecosystem services are currently included in urban plans. The ultimate objective is to un
The location of embryonic lymph node development is determined by the initial clustering of lymphoid tissue-inducer (LTi) cells. Here we demonstrate that both the chemokine CXCL13 and the chemokine CCL21 attracted LTi cells at embryonic days 12.5-14.5 and that initial clustering depended exclusively on CXCL13. Retinoic acid (RA) induced early CXCL13 expression in stromal organizer cells independen

This thesis sets out to examine the relationship between integration of the Common Market of the EU and European competition legislation. More specifically, it aims to answer three questions. Firstly, whether competition law has succeeded in what it was set out to do, namely further integration of the markets of the Member States. Secondly, to what extent the aim of integration has helped shape th
The addition of environmentally friendly items to conventional items sometimes leads people to believe that the carbon footprint of the entire set decreases rather than increases. This negative footprint illusion is supposedly underpinned by an averaging bias: people base environmental impact estimates not on the total impact of items but on their average. Here, we found that the illusion’s magnit
This thesis was conducted to assess how the broadening of trade, through Internet-enabled businesses and commerce, was affecting economic, social, and environmental sustainability. It identifies the threats and opportunities associated with the expansion of trade online, in addition to evaluating some of the implications a changing trade and commerce landscape could have on trade rules and policy.
Hudcancer, inklusive malignt melanom, keratinocytcancer (tidigare icke-melanomhudcancer) och också mer sällsynta hudcancerdiagnoser ökar snabbt i de flesta ljushyade populationer. En hudcancerdiagnos ger inte bara inverkan på hälsoekonomiska mätvärden utan också främst på individens livskvalitet. I vår forskargrupp fokuserar vi på kliniskt baserad och registerbaserad hudcancerforskning men även tiSkin cancers, including malignant melanoma, keratinocyte cancer (formerly non- melanoma skin cancer) and also more rare skin cancers are increasing rapidly in most fair-skinned populations. A skin cancer diagnosis has impact not only on health economics but also on the quality of life of the individual. In our research group we focus on clinical skin cancer research as well as on translational ski
A new influenza virus that was first detected in people in April 2009, was initially referred to colloquially as "swine flu", since it contained genes from swine, avian and human influenza viruses. It can, however, not be transmitted by eating pork or dealing with pigs. In Egypt, several hundred thousand pigs were killed in May, in spite of advice from global health authorities that such an action
