Aim: To characterize postnatal changes in serum IGF-I in relation to development of bronchopulmonary dysplasia (BPD) in very preterm infants. Methods: Longitudinal study of 108 infants with mean (SD) gestational age 27.2 (2.2) weeks. Weekly serum samples of IGF-I were analyzed from birth until postmenstrual age 36 weeks. Multivariate models were developed to identify independent predictors of
Organic solar cells made of polymers are an attractive alternative to the conventional solar cells which are commercially used today. The polymer solar cell is cheap to produce, due to the high absorption coefficients which limits the needed thickness of the material and due to the simple manufacturing process, which doesn’t demand high temperatures. However, the efficiencies of polymer solar cell
BACKGROUND: Toluene di-isocyanate (TDI) is widely used in the production of polyurethane foams and paints. As TDI causes respiratory disease in only a fraction of exposed workers, genetic factors may play a key role in disease susceptibility. Polymorphisms in TDI metabolising genes may affect elimination kinetics, resulting in differences in body retention, and in its turn differences in adverse e
The current institutional framework for sustainable development is by far not strong enough to bring about the swift transformative progress that is needed. This article contends that incrementalism-the main approach since the 1972 Stockholm Conference-will not suffice to bring about societal change at the level and speed needed to mitigate and adapt to earth system transformation. Instead, the ar
Detta examensarbete behandlar främst de sakrättsliga verkningarna av en aktieöverlåtelse, samt den centrala värdepappersförvararens ansvar för skada. De två sakrättsliga exempel som behandlas i denna uppsats är konsekvenserna av att aktiebrev inte är utgivet i kupongbolag, samt förkommet aktiebrev. Sedan behandlas även den centrala värdepappersförvararens ansvar för skada enligt 7 kap LKF. UppsatsThis thesis deals primarily with the impact on right in rem of stock transfer, and the CSD:s liability for damage. The two substantive examples treated in this thesis are first the consequences of a situation when no shares certificates are issued, and secondly a loss of share certificates. Additionally the CSD:s liability for damage according to chapter 7 in LKF will be treated. The thesis sums u
Company description: The Company is situated any ten kilometres outside Helsingborg and manufactures waffle cones, both for consumer and for industry. The company is private own and have 2 employees, the company’s turnover is 1.3 million SKr. Problem formulation: Below give a short brief problem formulation by Technique bridge foundation in Lund. Problem description: A packaging equipment that can
In order to overcome the shortcomings of crash data a number of surrogate measures of safety have been developed and proposed by various researchers. One of the most widely used temporal indicators is time-to-collision (TTC) which requires the road users to be on a collision course. Road users that are strictly speaking not on a collision course actually might behave and take evasive actions as if
Extending the lifetime of products is seen as a key objective for realising the vision of a Circular Economy. One way to increase the lifespan of products is to enable more repair activities. However, consumers encounter a variety of barriers for repairs, prompting public authorities in Europe and the US to adopt or propose policies in support of consumer repairs. Sweden has recently adopted a cir
Varje år ökar världens energiförbrukning på grund av befolkningstillväxt och ökande levnadsstandard. Vi står inför många stora problem, till exempel klimatförändringar, uttömning av fossila energikällor (t. ex. petroleum, kol och naturgas) och miljöföroreningar. Därför är det brådskande att söka efter förnyelsebar energi och hur människor kan använda energi så effektivt och ändamålsenligt som möjlThe demand and consumption of energy is increasing dramatically all around the world. Broad adoption of fossil fuels has triggered an enormous threat to the environment. To ensure sustainability of our species and habitat, new solutions to fulfill the energy demand have to be found. Innovative materials offer the possibility to generate scalable renewable energy, which is efficient and environment
We investigated interactions within chimera states in a phase oscillator network with two coupled subpopulations. To quantify interactions within and between these subpopulations, we estimated the corresponding (delayed) mutual information that—in general—quantifies the capacity or the maximum rate at which information can be transferred to recover a sender's information at the receiver with a van
Rwanda’s Nyabarongo catchment frequently experiences floods, highlighting the need for effective flood susceptibility analysis and management. This study mapped flood susceptibility in the catchment using the random forest (RF), support vector machine (SVM), eXtreme Gradient Boosting (XGBoost), SHapley Additive exPlanations (SHAP) models, as well as various conditioning factors including elevation
BackgroundIt remains unclear as to why some individuals at low risk of cardiovascular disease (CVD) develop severe coronary atherosclerosis, while those at high CVD risk may remain free from coronary atherosclerosis.PurposeUsing Coronary Computed Tomography Angiography (CCTA), we aimed to identify factors associated with absence and severe coronary atherosclerosis in subjects from the general popu
The Millennium Development Goals (MDGs) were an important precursor to the Sustainable Development Goals (SDGs). Hence, identifying the conditions that made the MDGs successful enhances our understanding of global goal-setting and informs the global endeavour to achieve the SDGs. Drawing on a comprehensive review of 316 articles published between 2009 and 2018, we identify six factors that have en
Robot skills systems are meant to reduce robot setup time for new manufacturing tasks. Yet, for dexterous, contact-rich tasks, it is often difficult to find the right skill parameters. One strategy is to learn these parameters by allowing the robot system to learn directly on the task. For a learning problem, a robot operator can typically specify the type and range of values of the parameters. Ne
Agriculture plays a central role in the economy of Nepal, serving as a major source of income and employment for much of the population. This study was conducted as part of the Solar Food: Reducing Post-harvest Losses project, a collaboration between Lund University, Kathmandu University, and The Royal Institute of Bhutan. The project aims to design solar dryers to reduce post-harvest losses in ru
