District heating is well expanded in the residential areas in Sweden, although not in detached house areas. Increased environmental concerns as well as steadily increasing electricity and oil prices make the detached houses sector a potential market for the district heating companies. District heating in low heat density areas is economically challenging for mainly two reasons: Firstly, constructi
We have recently observed that DDT and a DDT metabolite, DDOH, conjugated to a fatty acid, palmitic acid, DDOH-PA, affects muscarinic cholinergic receptors (MAChR) in the neonatal mouse brain when given to suckling mice during rapid brain growth. This early exposure of the neonatal mouse also affects the behaviour of the animals as adults. When DDT and DDOH-PA was given as a single low oral dose o
Popular Abstract in Swedish Växter påverkar marken rent mekaniskt genom att jordstrukturen ändras när en rot växer, men också kemiskt genom att rötterna utsöndrar organiska molekyler. De organiska molekylerna ökar näringstillgången för mikroorganismerna i marken och därmed ändras tillväxthastigheten och biomassan hos mikroorganismerna. I området runt rötter, rhizosfären, råder det därför en hög miMicrobial activity in soil is generally assumed to be limited by carbon availability. The soil closest to roots, the rhizosphere, is therefore a zone of high microbial activity due to carbon containing substances released by the root. In this work short-term effects in the rhizosphere have been the subject of investigation. I have shown that the thymidine and leucine incorporation techniques are w
Popular Abstract in Swedish Slemhinnorna i näsan, bihålorna, nasofarynx (nässvalgrummet), örontrumpeten och främre delen av mellanörat, är beklädda med celler på vars yta det finns flimmerhår (cilier). De ciliebeklädda slemhinnorna är täckta av ett tunt slemskikt som transporteras av ciliernas rörelser. I slemskiktet fastnar inandade partiklar, bakterier och döda celler, och transporteras av cilieThe aim with this thesis was to investigate effects of vasoactive mediators on mucociliary activity and blood flow in rabbit and human experimental models. Mucociliary activity in vivo and ciliary beat frequency (CBF) in vitro were measured with photoelectric techniques. Blood flow was measured with laser Doppler flowmetry. Substance P (SP) and methacholine increased human nasal blood flow. Pretre
Popular Abstract in Swedish Därför får man sockersjuka (Felix Mulder, 6 år): ”Det är inte bra att äta för mycket socker. Socker är vasst och skär sönder blodkropparna. Då kan man inte göra insulin och man blir sjuk.” Islet amyloid polypeptide (förkortat: IAPP) är ett medelstort äggviteämne - peptid - som upptäcktes 1986 av Per Westermark i Uppsala. Denna upptäckt har en intressant bakgrund. Det hIslet amyloid polypeptide (IAPP; also named ”amylin”) is a member of the calcitonin superfamily of peptides, displaying the closest structural relationship to the neuropeptide calcitonin gene-related peptide (CGRP). It is expressed in islet beta-cells and forms islet amyloid in type 2 diabetic patients. IAPP may restrain release and peripheral actions of insulin. Thus, IAPP has been implicated in
Information technology is a vital driver in today’s business environment. Recent developments of IT have facilitated for the relatively easy creation of markets on the Internet, so called B2B-marketplaces. However, judging from the survival rate of B2B-marketplaces (5 to 10 per cent), it seems like B2B-marketplaces are doing something wrong. This paper scrutinises several theoretical frameworks re
Two new African species of Teloschistes are described: T. arabicus Frödén sp. nov. and T. inflatus Frödén sp. nov. T. arabicus is a montane species, occurring in the southern parts of the Arabian peninsula and the adjacent parts of eastern Africa. T. inflatus is only known from South Africa, and was previously included in T. perrugosus Müll.Arg. Useful characters for distinguishing the misundersto
Popular Abstract in Swedish Kost, livsstil, antioxidanter och riskfaktorer för cancer De flesta forskare är överens om att våra matvanor spelar en betydande roll för risken att insjukna i cancer. Däremot är forskarna inte överens om vad och hur man bör äta för att förebygga cancer. En populär teori under det senaste decenniet har varit den så kallade antioxidantiahypotesen. Man har förstått att This thesis examines associations between a number of epidemiological or biological markers of cancer risk and oxidative stress, in order to achieve a better understanding of how diet, lifestyle, and genetic factors contribute to the occurrence of oxidative stress. Data from the Malmö Diet and Cancer (MDC) cohort was used. The MDC study is a population-based cohort study which uses a detailed modi

Housing is a basic human need throughout the world. Most people the world over have problems getting a place to sleep. In spite of the importance and necessity of housing a number of governments barely work to support the rental housing sector in many national housing policies. Housing which is a social service is now considered more as economic good which is being traded in as a commodity. The ho
We aim to measure the effect of relationship building between target-firm and financial advisor in the Mergers and Acquisitions industry. We also aim to investigate what affects the target-firm’s decision to stay loyal or switch financial advisor. Our main findings show that relationship building does not have a significant effect on the advisor fee and speed of transaction. Instead of earlier c
Objectives: Old-generation drug-eluting coronary stents (o-DES) have despite being safe and effective been associated with an increased propensity of late stent thrombosis (ST). We evaluated ST rates in o-DES, new-generation DES (n-DES) and bare metal stents (BMS) the first year (< 1 year) and beyond 1 year (> 1 year). Methods: We evaluated all implantations with BMS, o-DES (Cordis Cypher, Boston
This paper aims to study what influence different meteorological parameters have on the radial tree growth of Scots pine (Pinus sylvestris L.) in peat and mineral soils, as well as to make predictions of radial tree growth responses to changing climate based on various future climate projections. Four Lithuanian peatland complexes representing different geographical settings and hydrological condi
The variables of snow cover extent (SCE), snow cover duration (SCD), and snow albedo (SAL) are primary factors determining the surface energy balance and hydrological response of the cryosphere, influencing snow pack and glacier mass-balance, melt, and runoff conditions. This study examines spatiotemporal patterns and trends in SCE, SCD, and SAL (2000–2016; 16 years) for central Chilean and Argent
Purpose: We examined if data-driven food-patterns associate with weight change, incidence of type 2 diabetes (T2D), coronary events (CE) and stroke. Methods: The study included 20,487 individuals (61% women) from the Malmö Diet and Cancer cohort, 45–74 years, without diabetes and CVD at baseline (1991–1996) and who did not report dietary changes. Diet was measured with a modified diet history meth
Based on extensive ethnographic fieldwork in Uzbekistan, this article looks at the way official state narratives are challenged by silent, unorganised, often unaware gestures of resistance at the bottom of a society. Footing on a framework suggested by Scott’s definition of infrapolitics (2012), we propose to incorporate informal practices in a definition of informality that is more inclusive and
