Examensarbetet presenteras som en nulägesanalys av hur verksamheter inom bygg- och rivningsbranschen lever upp till de lagar och bestämmelser som reglerar byggsektorn och hur sektorn arbetar med miljöfrågor i hela kedjan, med fokus på avfallshantering. Studien är tänkt att fungera som ett hjälpmedel för Miljökontoret i Helsingborgs Stad vid deras framtida tillsynsarbete. Nulägesanalysen bygger på
Problemställning: Idag utgör byggnader 40 % av den Europeiska unionens sammanlagda energianvändning. Europaparlamentets och rådets direktiv 2010/31/EU antogs den 19 maj 2010, vilket verkar för att öka användningen av förnybara energikällor och samtidigt minska energianvändningen. Direktivet beskriver att medlems-staterna ska ta ansvar för att alla nya byggnader är nära-nollenergibyggnader senast Question: Today, buildings are responsible for 40 % of the total energy consumption in the Union. Directive 2010/31/EU of the European Parliament and Council was adopted May 19th of 2010 whose purpose is to increase the usage of energy from renewable sources and to reduce energy consumption. Article 9 states that by December 31st of 2020, all new buildings are supposed to be nearly zero-energy bu
Linear pi-conjugated oligomers have been widely investigated, but the behavior of the corresponding cyclic oligomers is poorly understood, despite the recent synthesis of pi-conjugated macrocycles such as [n]cycloparaphenylenes and cyclo[n]thiophenes. Here we present an efficient template-directed synthesis of a pi-conjugated butadiyne-linked cyclic porphyrin hexamer directly from the monomer. Sma
Popular Abstract in Swedish Prostatacancer är den vanligaste formen av cancer hos män i Sverige och ungefär 10 000 män diagnosticeras årligen. Prostatacancer tros orsakas av en kombination av ärftliga faktorer och miljö-/livsstilsfaktorer. De enda väletablerade riskfaktorerna för prostatacancer är ålder, etnicitet och ärftlighet inom familjer. För att kunna arbeta med förebyggande av denna sjukdomProstate cancer (PCa) is a heterogenous disease including very aggressive lethal tumors to incidentally discovered clinically insignificant tumors. Age, ethnicity, and family history are the only established risk factors. Type 2 diabetes mellitus (T2D) has been found to associate with increased overall cancer risk but with lower risk of specifically PCa. T2D is initially associated with increased
Using a combination of experimental and theoretical techniques, we show that a thin RhO2 surface oxide film forms prior to the bulk Rh2O3 corundum oxide on all close-packed single crystal Rh surfaces. Based on previous reports, we argue that the RhO2 surface oxide also forms on vicinal Rh surfaces as well as on Rh nanoparticles. The detailed structure of this film was previously determined using U

OBJECTIVES: This is a protocol for a Cochrane Review (prototype). The objectives are as follows: Primary objective To determine the prognostic value of birth weight (BW) and prematurity in predicting the incidence of type 2 diabetes mellitus (T2DM) later in life (among adults, adolescents, and children) compared to normal BW and full-term birth. Secondary objectives To determine the prognostic val
In the paper, we consider the problem of routing and bandwidth allocation in networks that support elastic traffic. We assume that the bandwidth demand between each source-destination (S-D) pair is specified in terms of a minimum and maximum value, and a set of flows between each S-D pair is allowed to realize these demands. (We say that a set of flows realizes the demand associated with an S-D pa
Background: Psychological resilience refers to a person's positive adaptation when faced with adversities, such as a breast cancer (BC) diagnosis. Highly resilient patients are more likely to regain stability and be protected from health conditions such as depression, anxiety, and posttraumatic stress disorder. We aimed to identify epigenetic markers that distinguish high- and low-resilient patien
Introduction: Postnatal pesticide exposure and its association with child and adolescent behavioural outcomes remain underexplored in rural agricultural settings, particularly in Africa. This study examined behavioural outcomes in relation to urinary pesticide biomarkers and contextual exposure proxies in participants from the Child health Agricultural Pesticide (CapSA) cohort, South Africa. Metho
BACKGROUND AND AIM[|]The incidence of skin cancer has risen sharply over the past 30 years - coinciding with the rapidly increasing tattoo trend. In Sweden, 20% of the population is tattooed. The link between tattoos and skin cancer needs to be investigated, due to the presence of carcinogenic chemicals in tattoo ink, and the lack of epidemiological studies of the association. We aimed to investig
BACKGROUND: Sexual violence against older adults in humanitarian settings is poorly documented, leading to gaps in prevention and delivery of support services. This study aimed to document differences in assault characteristics between younger and older adults, by sex and displacement and disability status and region. METHODS: This retrospective, descriptive observational, multi-country study incl
Introduction: Cell-free DNA is an emerging marker of allograft injury, yet its role in the immediate phase of ischemia–reperfusion injury remains incompletely understood.Methods: In this prospective cohort of 127 kidney transplant recipients (86 deceased donors, 41 living donors), intraoperative plasma samples were collected systemically pre-implantation and from the allograft vein postreperfusion
Spindle cell lipomas (SCL) and pleomorphic lipomas (PL) are today considered a single tumor entity (SCLPL). Atypical SCLPL, in contrast, represents a recently recognized related but distinct entity. Here we explored the correlation between genomic features and morphological aspects of SCLPL and atypical SCLPL and the role of the RB1 gene in tumor development. Seventy-one samples from 68 patients w
In most industrial product development projects, computer-based design analysis, or simply design analysis, is frequently utilized. Several design analysis process models exist in the literature for the planning, execution and follow-up of such design analysis tasks. Most of these process models deal explicitly with design analysis tasks within two specific contexts: the context of design evaluati
Our everyday experiences show that the lack of needed information in various human affairs may give rise to consequences that we would like to avoid – e.g. the 2004 Tsunami in Southeast Asia. However, we still do not have a coherent theoretical body that addresses such experiences of information inadequacy as this changes everything in respect to the current conception of the information society,
Antibodies against P. falciparum merozoites fix complement to inhibit blood-stage replication in naturally-acquired and vaccine-induced immunity; however, specific targets of these functional antibodies and their importance in protective immunity are unknown. Among malaria-exposed individuals, we show that complement-fixing antibodies to merozoites are more strongly correlated with protective immu
Although the projected changes in the climate include considerable uncertainties, especially with downscaling, there is irrefutable evidence that the climate is changing at an unprecedented and alarming rate. In recent studies, some of the potential climate-change risks on bridges have been identified. The sheer number of these potential risks provokes two questions. Firstly, for a certain risk of
Recombinant antibody libraries can provide a source of renewable and high-performing binders tailored for use in affinity proteomics. In this context, the process of generating site-specific 1:1 tagging/functionalization and/or orientated surface immobilization of antibodies has, however, proved to be challenging. Hence, novel ways of generating such engineered antibodies for use in affinity prote
Många beteenden hos djur kan vara oflexibla och mer eller mindre ”hard-wired” i hjärnan. Sådana beteenden kan vara ändamålsenliga för regelbundna och rytmiska förändringar i naturen, såsom dag och natt, årstider, etc. Men många faktorer är naturligtvis oförutsägbara i naturen. För sådana oförutsägbara förändringar är det bättre för djur att vara flexibla i sitt beteende. Kognition är en process soThe Paridae (tits, titmice and chickadees) is a bird family consisting of both food hoarding and non-hoarding species. Many studies have been conducted on birds that are considered to be cognitively advanced, such as parrots and corvids, whereas much less is known about these small passerines. In this thesis, I have investigated the cognitive abilities of two members of the Paridae family; marsh t
